Description

The subject of the invention is a support system for positioning patient in lateral position during surgery procedures using an improved socket connector assembly.
Conventional support systems are widely used during specific surgery procedures, like hip arthroplasty or hip fracture, which require stabilization of a patient in one lateral position for many hours. In order to provide an access to the surgical site, it is often necessary to place patient in an unnatural position, simultaneously maintaining patient safety and comfort.
Document US6820621B2 discloses system for positioning a patient in lateral position during hip replacement or hip surgery, which consists of a sacral support unit arranged for attachment to an operating table and a pelvic support unit. The pelvic support unit comprises an extension arm enabling height adjustment, a horizontal arm enabling width adjustment and rotary arm ended with a pelvic support plate. In system according to US6820621B2 , the support plate is rigidly attached to the rotary arm without possibility of changing its angular position. As a consequence the solution itself does not solve the problem of abrasions occurring during surgery procedures, being result of contact between support elements and the skin of the patient.
Document US6298507B1 describes support system configured as an adjustable table attachment apparatus adapted for attachment to an operating table and supporting patient in lateral position during surgery procedures. Said adjustable table attachment apparatus comprise a generally U-shaped tubular frame having vertical legs adapted at their lower ends to be removable received and secured on opposed sides of an operating table and rectangular top platform having one end adapted to be removable attached to horizontally-extending rail of U-shaped frame. The U-shaped frame comprises also two pelvic positioners connected with the padded plates made of the rigid material by means of rigid connection to an end a pelvic positioner. Consequently, movement of the padded plates is limited as the padded plate is oriented in a transverse plane spinning around the connection on the end of an arm the pelvic positioner is possible before orienting adjacent the patient in the chosen immobile position. The rigid construction of the padded plates in the transverse plane provides no possibility of combined angular and rotational movement. The rigid padded plate of these adjustable table attachment apparatus is uncomfortable, has lower adaptation of the apparatus to the anatomical construction of the patient, and may result in a high risk of skin abrasions and/or trauma.
Document US7426930B1 discloses a surgical support device comprising a rigid support plate arranged for attaching to a hospital bed with upstanding front and rear support. The front support apparatus further comprises a top and bottom arm terminating in top and bottom patient support pads, wherein a top patient support pad is made of compression foam material and removably attached to the top plate by using of a top plastic clip on one side thereon. This solution provides greater patient comfort during contact with a support device, but due to the lack of angular and rotational movement of the support pad, the surgical support does not solve the problem of slipping of the obese or otherwise oversized patients as the support plate is in a fixed position.
The prior art solutions are not sufficiently adapted for stabilizing position of wide range of physical sizes of patients. It would be desirable therefore to provide a support system allowing wide dimensional adjustment range, preventing slipping off the obese patients, which does not result in unnecessary pressure on the surface of the patient's skin, at the same time.
The disadvantages of the prior art solutions are solved by a support system according to the invention.
The gist of the invention is a support system for a side rail on lateral edge of an operating table, for positioning patient in lateral position during surgery procedures, comprising a first support unit which further comprises a first high adjustable arm and a second length adjustable arm and the first support unit configured for supporting a lumbar area of the patient and comprising a second support unit, which further comprises an arm for positioning a pad plate connected to a support plate, with a support pad adjacent to the patient, the second support unit being connected to the second length adjustable arm to extent over the patient and the arm being configured to position the support pad adjacent an iliac crest of the patient.

Another vertical plate 119 includes a radial slot 115 for rotatable adjustment of the first high adjustable arm 130 and secured by the associated knob 132 in the construction of first high adjustable arm 130. The first high adjustable arm 130 comprises the knob 132, an adjustment knob 138, an arm segment 136 and an arm segment 136, whereby the arm segment 134 is configured to be received in arm segment 136. The arm segment 134 is adapted to receive the fastener of the knob 132 for establishing and holding an angular position of the first high adjustable arm 130. The arm segment 136 is configured of a larger dimension than the arm segment 134 so as receive arm segment 134 therein. The arm segment 136 is adapted with an opening located on arm segment 136 to receive a securing fastener associated with the adjustment knob 138 for adjustment of height of the adjustable arm 136. The adjustment knob 138 is configured to secure the arm segments 134, 136 in a desired position, for example, allowing regulation of height of the first high adjustable arm 130 and for securing in a desired position relative to the patient 101.
As shown in FIG. 1 the first high adjustable arm 130 and the second length adjustable arm 140 are connected by the using of knob 142 and for securing in a desired position. According to this embodiment of the invention a knob 142 connects the second length adjustable arm 140 with the second support unit 160 and knob 162 operably connects the connector 168 to receive the arm 170 in the opening 167 formed in the body of the connector 168 allows manipulating of position of a rotatable curved arm 170 relative to the length adjustable arm 140. The rotatable curved arm 170 is connected movably through degrees of movement being disposed in the opening 167 of the connector 168 and tightened or loosened by the knob 162. A pad plate 202 is configured to be operably connected for angular movement relative to the arm 170, as shown in FIG. 1.
Referring to FIGS. 1-5, the pad plate 202 is configured to operably connect with a support plate 220 and a support pad 230 affixed thereto by the segmented protrusions 244 of a biasing connector 240. The biasing connector 240 may be formed of plastic as a part of support plate 220 configured to connect to the pad plate 202. The support pad 220 in this embodiment of the invention is formed in an oval - shape and made of compressive foam material and is in contact with the body part of the patient 101. The support pad 230 may further have a construction of a support pad 230 of a density of gel, foam, closed cell memory foam, or other suitable compressive material, e.g. firm, and second support pad 232 of another density of compressive foam material, e.g. soft so as to provide better adaptation to the anatomical construction of the patient 101 and eliminates the risk of the skin abrasions. The support plate 220 is angularly rotationally movable as connected to the pad plate 202 under the influence of an external force F1, exceeding the threshold value being the friction force F2 between segmented protrusions 244 of a biasing connector 240 and the pad plate 202 so as force or press against the patient 101 to support and hold the patient 101 in a desired position for a surgical procedure.
FIG. 2 shows in details the construction of the support plate 220 comprising a biasing connector 240 with segmented protrusions 244 according to the first embodiment of the support system 100. The biasing connector 240 may be configured on a portion of the upper surface 222 with intervals 270, for example, centrally located to project on an upper surface 222 of the surface of the support plate 220 for positioning adjacent a circle plane of the pad plate 202 in a channel 241. On a lower surface 224 of the support plate 220 is configured to secure and affix the support pad 220 thereto so as to be positioned adjacent the patient 101, which securing may be accomplished by adhesives. In this embodiment of the invention the support plate 220 is configured in four segmented protrusions 244 of the biasing connector 240, identical in design, and four intervals 270. The segmented protrusions 244 may be configured approximately T-shaped in cross-section and have an elongated base plate support segments 242, e.g. a protruding part of the T-shaped cross section. The segmented protrusions 244 may be configured with a protrusion 246 with a lip 248 (e.g. tooth-like) inclined at an angle to the upper surface 222 of the support plate 220. The segmented protrusions 244 may be configured with a channel 241 for holding lateral edge 207 of the pad plate 202 so as to secure the pad plate 202 to the support plate 220. The base plate support segment 242 is configured to support the pad plate 202 in spaced relation a distance apart from the support plate 220 parallel to the surface of the support pad 230. The base plate support segments 242 and protrusions 246 may be configured with the diameter smaller than diameter of the lateral edge 207 of the pad plate 202 which are arranged in a plane above the surface of the support plate 220, permitting maintenance of the pad plate 202 on the base plate support segments 242. An opening 250 may be formed extending through the upper surface 222 and lower surface 224 of the support plate 220 to allow passage of air and/or fluids that may accumulate in the support pad 230 whereby such fluids can flow through openings 226 and emanate from the support plate opening 250.
As shown in FIG. 3 the rotatable curved arm 170 is connected with pad plate 202 by the using of connection 180, which in this embodiment of the invention comprise a pin 260 disposed through openings 206, 262 to join a post 204 in the slot 172 formed in the arm 170 in a rotatable connection. According to this embodiment of the invention the slot 172 is configured on the end of rotatable curved arm 170 of a dimension enabling degrees of freedom movement of the post 204, pad plate 202, and any attached support plate 220 and support pad 230. In operation, the arm 170 can force the support pad 230 and/or second support pad 232 against the upper iliac crest 179, with angular displacement of the pad plate 202 attached to arm 170 resulting in the support pad 230 and/or 232 adjusting to the anatomy of the patient 101 to support and hold in the desired position as illustrated in FIGS 1-4. Similarly, a ball and socket connector 164 assembly between the arm 170 and pad plate 220 can force the support pad 230 and/or 232 against the upper iliac crest 179 resulting in the support pad 230 and/or 232 adjusting to the anatomy of the patient 101 to support and hold in the desired position as illustrated in FIGS. 4 and 5.
FIG. 4 shows second embodiment of the support system 100 with a third support element 190 mounted to the opposite side rail 103 on a lateral edge 107 of the operating table 102 relative to the first support unit 110. The third support element 190 comprises the bottom plate 192, horizontal arm 196, crossbar 196a, and tabular support pad 198 operably connected to the crossbar 196a mounted to the third support element 190 for supporting the pelvic area and/or lower anterior iliac crest 199 to maintain the patient 101 in the desired stationary position. In this embodiment of the invention the bottom plate 192 of the third support element 190 comprises moreover an adjustment knob 194 allowing adjusting of the third support element 190 along side rail 103 of the operating table 102. In operation, the third support element 190 can force the tabular support pad 198 against the pelvic region and/or iliac crest 199 of the patient 101 to support and hold in the desired position as illustrated in FIG. 4.
Referring to FIG. 2, Fig.3 and Fig.5, the support system 100 according to the invention is characterized by the support plate 220 being angularly rotationally thereby making movable around the pad plate 202 under the influence of an external force F1, exceeding the threshold value. It is therefore possible to eliminate the risk of undesirable displacement of the support plate 220 from the adjusted position. Referring to FIGS. 2 and 5, the support system 100 comprises a biasing connector 240 consisting of base plate support segments 242 with one or more protrusions 244 extending to support a lower surface 205 of the base plate 202 and elongated protrusion 246 having a lips 248 or tooth end extending beyond a forward face or upper surface 203 surrounding the lateral edge 207 of a portion of the support plate 220 so as to secure the pad plate 202 to the support pad 230. The biasing connector 240 comprises intervals 270 forming the elastic segmented protrusions 244 allowing for the support pad 230 to be operably connected to the pad plate 202 of the pad assembly 200. The biasing connector 240 may be formed from suitable materials having elastomeric properties, resistant to bending and abrasions, including of metals, metal alloys, polymers and elastic materials. The use of these types of materials allows for the clamping the pad plate 202 easily to the support plate 220 and simultaneously prevents surface damages in the point of contact between the base plate support segments 242 and protrusion 244 along with the protrusion 246 and lip 248 securing the lateral edge 207 of the pad plate 202 therein.
Referring to FIGS. 2-3 and 5, the support system 100 according to the invention is characterized in that the segmented protrusions 244 of the biasing connector 240 are arranged on the upper surface 222 of the support plate 220 that can be formed to allow for the clamping the pad plate 202 easily to the support plate 220, for example, in a circle with intervals 270 on the support plate 220 structure. This type of construction simplifies the rotational movement of the support plate 220 in relation to the pad plate 202 by reduction of numbers of points of contact between support plate 220 and pad plate 202 and therefore the friction force between them. Moreover, increases the possible range of angular moves of the rotatable curved arm 170 as shown in FIG. 1, for example, to 180° degrees, thereby allowing the rotatable curved arm 170 to engage the anatomy of the patient 101 to force and/or press the support pad 230 against the patient 101 using to the lower surface 205 of the pad plate 202.
Referring to FIGS. 2-3 and 5, the support system 100 is characterized in that the segmented protrusions 244 are configured for securing a lateral edge 207 of the pad plate 202 within a channel 241 formed by the protrusion 244 and the lip 248 of the protrusion 246 in the biasing connector 240 as shown in FIGS. 2 and 5. The segmented protrusions 244 of a biasing connector 240 may be formed approximately T-shaped in cross-section having the protruding part of the T -shaped cross-section being the segmented protrusion 244 for supporting the base plate 202 by baseplate support segments 242. Similarly, the upper surface 203 of the base plate 202 engages protrusions 246 for securing lateral edge 207 in the channel 241 by the lip 248 of the protrusion 246 as shown in FIGS. 2 and 5. The protrusion 246 and lip 248 may be formed inclined at an angle to upper surface 203 of the base plate 202 for securing lateral edge 207 in the channel 241 and for seating the lower surface 205 against the protrusion 244 thereby suspending the pad plate 202 above the upper surface 222 of the support plate 220 with openings 226 forming a flow channel for air, fluids and the like emanating from the opening 250, for example, air and/or fluids can seep into the support pad 230 and second support pad 232 and be released through the opening 250 and out the intervals 270. The flow of air through the opening 250 has advantages in removing trapped air from the support pad 230 and/or second support pad 232 for improved securing of the patient 101 in the support system 100 and also providing increased comfort to the patient 101 by allowing any trapped air to escape thereby decreasing abrasions, hot spots and/or damage to tissue. Consequently, the support system 100 of the invention improves the function of maintaining the patient 101 in the fixed position using arm 170 engaging the pad assembly 200 against the anatomy of the patient 101, e.g. with the support pad 230 connected to the support plate 220 angularly engaging the patient 101 to the support arm 170 as being rotatable connected to the pad plate 202 by the connection 180 of, for example, the pin 260 engaging the slot 172 in the arm 170 and opening 206 in the post 204 and/or using the ball and socket connector assembly 180. A rotatable connection 180 is configured to operably connect the pad plate 202 in the channel 241 formed by the baseplate support segments 242 and lip 248 and the other parts of construction of the segmented protrusions 244 of a biasing connector 240, as illustrated in FIGS. 3 and 5. At the same time the pad plate 202 is easily removable from the channel 241 as the protrusion 246 of the biasing connector 240 releases from the segmented protrusions 244. The pad plate 202 can engage the channel 241 of the support plate 220 by pressing the oval plate into the biasing connector 240. This type of construction of the invention advantageously provides removal of the pad plate 202 from the support plate 220 so that the support pad 230 and/or support pad 232 can be removed after the surgical procedure for reuse of the support system 100 after sterilization.
Referring to FIG. 2, the support system 100 according to the invention is characterized in that pad plate 202 is elevated above the support plate 220 by the lower surface 205 being supported support segments 242 so as to form flow through intervals 270. Moreover, the support plate 220 comprises a support plate opening 250 extending between the surfaces 222 and 224 thereof with the flow of air and/or fluids out of opening 250 for release of any fluids trapped in the second support pad 232 any trapped air that leads to elimination of the friction force against the patient 101.
Referring to FIGS. 2 and 5, the support system 100 according to the invention is characterized in that lateral edge 207 of the pad plate 202 has diameter lower than the diameter of circle of biasing connector 240 for operably connecting thereby and forming an operably biasing connection on the plane of which the segmented protrusions 244 are arranged of biasing connector 240. This construction of the pad assembly 200 allows rotation of the pad plate 202, support plate 220, and the support pad 230 and or second support pad 232 relative to the arm 170 that lead improved positioning, greater patient comfort, flow of air and or fluids from the pads 230 and/or second support pad 232, and elimination of the friction force against the patient 101. Diversification of mentioned diameters enables maintaining the pad plate 202 in the channel 241 elevated above the upper surface 222 and simultaneously reduces the friction between the pad plate 202 and the support plate 220. Furthermore the support system 100 according to the invention is characterized in that the support plate 220 utilizes an oval structure with a round arrangement of biasing connector 240 for connecting to the round pad plate 202. The application of movability of the pad plate 202 and support plate 220 respective of the arm 170 and anatomy of the patient 101 leads to elimination of the friction force between the pad plate 202 and the oval structure of the support plate 220 and thus the abrasion of materials of which these constructional elements are made to the patient 101.
Referring to FIGS. 2 and 5, the support system 100 according to the invention is characterized in that the support pad 230 is oval - shaped and made of compressive foam material. The support system 100 using the support pad 230 on the adjustable pad plate 202 provides better adaptation to the anatomical construction of the patient 101 and eliminates the risk of the skin abrasions. Moreover, the support pad 230 can be combined with second support pad 232 comprised of a different density to provide improved adaptation to the anatomical construction of the patient 101 and eliminates the risk of the skin abrasions
Referring to FIGS. 1-5, the support system 100 according to an embodiment of the invention is characterized by an operable connection between the support arm 170 and the pad plate 202 consisting of pin 260, opening 262 in the arm 170, and the opening 206 in the post 204. A slot 172 arranged on the end of the rotatable curved arm 170 is adapted to receive the post 204 extending from the upper surface 203 of the pad plate 202 and the pin 260 operably connects these structures, as shown by path 209 through the openings 206 and 262, by passing the pin 260 through openings 206, 262 positioned adjacent each other thereby allowing the pad plate 202 to rotate angularly in the slot 172 as shown in FIG. 2. This connection enables performing multiple degrees of movement of the pad plate 202 relative to the arm 170. The advantage of this solution is the ability to angular rotational movement of the pad plate 202 and/or the support plate 220 enables finding the best possible support for the patient 101, independently from the weight and physical size of the patient 101. At the same time, support system 100 maintains the patient 101 in the immobile, chosen position reducing the risk of the undesirable rolling off the patient 101 on the one side and eliminates the problem of skin abrasions occurring during surgery procedures from the first support unit 110 to the patient 101.
According to another embodiment of the invention illustrated in FIG. 5, a connection 180 may be formed in a ball and socket configuration to form the movable connection between the pad plates 202 relative to the arm 170 having a full range of degrees of movement. The connection 180 comprises a body 182 having a connection portion 184 slidably received in the arm 170 stopping at a flange 185, and a plate connection portion 186 on a opposite side of flange 185 configured with a socket portion 188. The pad plate 202 can be configured with a ball post 208 configured to be received in the plate connection portion 186 with the connection 180 enabling full degrees of movement of the pad plate 202 relative to the arm 170. Consequently, each of these embodiments of the invention enables improved range of freedom degrees move pad plate 202 and support pad 220 relative to the patient 101 to enable the support system 100 to find the optimal support for the patient 101 on the operating table 102 for a surgical procedure.
Referring to FIG. 5, the support system 100 according to the invention is characterized in that the support system 100 comprises a third supporting element 190 mounted to the opposite lateral edge side rail 103 of an operating table 102 relative to the first support unit 110. The provision of third supporting element 190 results in increased patient's stability by supporting the lower anterior iliac crest and/or pelvic area 199 of the patient 101. The third supporting support system 100 comprises a rail clamp with a knob 194 for securing to the side rail 103, a bottom plate 192, and a horizontal arm 196 with a crossbar 196a configured to receive the tabular support pad 198 on an end of the horizontal arm 196 located apart from the side rail 103 for positioning and supporting the lower anterior iliac crest and/or pelvic area 199 of the patient 101. Consequently, the horizontal arm 196 may be fixed to the side rail 103 by the mounting claim and supported in a horizontal position by the bottom plate 192 to enable the support assembly 100 to find the optimal support the lower anterior iliac crest and/or pelvic area 199 of the patient 101 on the operating table 102 for a surgical procedure.
