Japanese Patent Application No. 2004-266278 (P2004-266278)

There is a great difference between the installation of a tubular organ using a conventional endoscope operation training apparatus and the environment of an actual tubular organ. Since an actual tubular organ is bent not only in a straight line but also vertically and horizontally, there is a drawback that it cannot be accurately reproduced with conventional endoscope operation training apparatuses. In the esophageal canal, when examining or treating the diseased area, the surgeon sees the heart beat on the left side of the esophagus to compress the esophagus and deform the inner wall of the esophageal canal, so the actual technique is difficult, Because the environment cannot be reproduced, endoscopic surgery and inspection training in the state of an actual tubular organ cannot be performed. In addition, as shown in FIG. 2, in the large intestine, after rotating from the rectum to the upper resin net while turning into an S shape, it sinks to the back side while proceeding to the head, and returns to the abdomen side to form a left colonic curve. To do. Later, after the formation of the transverse colon, it has a complicated form that sinks to the back side again, forms a right colon curve, sinks into the lower resin network, and reaches the cecum, so it is supported at both ends with a conventional endoscopic operation training device It cannot be reproduced by the method.

The present invention has the disadvantage that it cannot be practiced in a precise situation because it could not be reproduced with a conventional endoscopic operation training device, and the organ placement system for endoscopic surgery / examination training and esophageal endoscopy It is solved by providing a pulsation device that can correct the difference with the environment.

The present invention can be realized by using an endoscopic surgical training organ placement system when it is desired to accurately reproduce the shape of an actual tubular organ. If you want to reproduce the surgical environment in which the heart beats the esophageal canal and deforms the inner wall of the esophageal canal, you can use the pulsating device.

When installing a tubular organ that moves up and down, the resin mesh is made up of two layers, the upper resin mesh is stretched in parallel, and the lower resin mesh is loosely stretched in a U shape to create a space between the upper and lower resin meshes. Partially cut the upper resin mesh, insert the tubular organ from the upper resin mesh into the lower resin mesh, and place the tubular organ in the space created between the upper resin mesh and the lower resin mesh, so that the tubular organ that goes up and down is reproduced and installed it can.

A curved tubular organ environment can be installed by suturing the tubular organ with a needle-attached suture and tying it to a resin net with a suture. Skill training is possible.

It is a tubular organ reproduction overview using the endoscopic surgery / inspection training organ placement system according to the present invention. FIG. 3 is an overview view of a large intestine reproduction using the endoscopic surgery / test training organ placement system according to the present invention. FIG. 4 is a left side view of an overview view of a large intestine using a two-layer resin network of an endoscopic operation / test training organ setting system according to the present invention. It is a general-view figure of the pulsation device concerning the present invention.

As shown in FIG. 1, the endoscopic surgery / inspection training organ placement system main body of the present invention is provided with an overtube holder, an organ ligation hook, and a netting hook for stopping a resin net.

As shown in FIGS. 2 and 3, the resin net can be used in two layers.

As shown in FIG. 4, the pulsation device of the present invention conducts the back-and-forth motion by transmitting the rotation of the drive unit to the extension device extension receiving unit.

The organ placement system for endoscopic surgery / inspection training of the present invention is shown in FIG. 1 by connecting both ends of a tubular organ to an overtube fixed to an overtube holder and an organ ligation hook, and pulling a net. Fine adjustment of the height, etc., can be stopped by a mesh hook and set to an actual tubular organ state.

The organ placement system for endoscopic surgery / inspection training according to the present invention can partially cut and insert (19, 22, 24, 26) a resin net as shown in FIG.

The organ installation system for endoscopic surgery / inspection training of the present invention can be installed in the lower part of the overtube by passing the magic tape of the overtube holder through the top plate to the bottom as shown in Fig. 2. It became possible to set to a different angle.

The endoscopic surgery / inspection training organ placement system according to the present invention can place a tubular organ, such as a large intestine that is excised from a living body and that bends vertically and horizontally, in an actual state. As shown in FIG. 2 and FIG. 3, the top plate bottom surface (1) is stretched in two layers on the top and bottom of the overtube (15) fixed with the elastic magic tape (29) of the overtube holder (4). The rectum (18) installed in the lower layer resin net (17) stretched in a U-shape is ligated among the formed resin nets. The tubular organ is inserted and penetrated into a hole in which the upper resin mesh is partially cut (19), and is formed on the upper resin mesh while forming the sigmoid colon (20). The tubular organ is sewn with a suture needle with thread, and the suture is meshed. Tie to (21). From there, partly cut the resin net again while facing the head (22) After insertion through the lower resin net (back side) (23), it came out again on the upper resin net to form the left colonic curve (24) It can be placed in the actual state of the large intestine reaching the cecum (27) by forming the right colon curve (26) through the formation of the transverse colon (25) and entering the lower resin network. Each shape forming portion is sewn with a suture needle with a thread, and the suture is tied to a mesh and fixed and installed, but the binding may be omitted depending on the installation situation.

The organ placement system for endoscopic surgery / inspection training of the present invention uses an elastic velcro tape on the overtube holder as shown in FIG. Easy to install, no over-tube to be used is specified, and installation with a higher degree of fixation is easier.

The main body of the organ placement system for endoscopic surgery / inspection training of the present invention is made of hard polystyrene, making it lighter and easier to handle than acrylic and easy to clean after use. There was no damage.

The pulsating device of the present invention can cause the same movement as the pulsation in the tubular organ (esophagus) by changing the rotational force of the round-cornered triangular rotating cam to the vertical movement with the extension rod.

By making the tip of the rounded triangular rotating cam of the pulsating device of the present invention into a large round shape, it is possible to smooth the exercise force to the extension part and create the same movement as the pulsation of the heart.

The organ stopper of the pulsating device of the present invention prevents the movement of the esophageal canal caused by the pushing force of the extension part.

The extension depth of the organ stopper can be adjusted and fixed by the fixing thumbscrew of the pulsating device of the present invention.

In the pulsating device of the present invention, since the number of pulsations of the patient varies depending on the physical condition, the number of pulsations is increased from 75 to 40 times with a rotary transmission dial in order to train the patient to cope with various patients. Can be changed.
