Abstract
The utility model provides a disposable endoscope mirror sheath provided with a telescopic mirror bridge. The disposable endoscope mirror sheath provided with the telescopic mirror bridge comprises an endoscope cavity in a mirror sheath, a mirror sheath body and the telescopic mirror bridge, wherein the rear end of the endoscope cavity is connected with the telescopic mirror bridge through the mirror sheath body. The disposable endoscope mirror sheath provided with the telescopic mirror bridge is characterized in that the telescopic mirror bridge is provided with a groove and a sealing ring, a limiting inserting piece is arranged inside the groove, and a clamping hole clamping the limiting inserting piece is embedded in the mirror sheath body. The disposable endoscope mirror sheath provided with the telescopic mirror bridge has the advantages that only the mirror sheath body, the telescopic mirror bridge and a silicon seal are needed, other parts are not needed, and the purposes that the telescopic mirror bridge can not be pulled out after inserted, the length can be regulated, and rotation is limited are achieved.
Description
Technical field
This utility model relates to medical instruments field, especially relates to a kind of disposable endoscope mirror sheath with telescopic mirror bridge.
Background technology
At medical field, such as urology department, related parts of human body inside is checked or during Minimally Invasive Surgery, the mirror sheath is the most frequently used endoscope's adnexa.For protection endoscope check and operation in not contaminated, avoid cross infection, for reducing the adverse effect that causes because of repeated multiple times sterilization, endoscope performance, clinical middle disposable endoscope sheath is used more and more extensive simultaneously.Endoscope's tract of this eka-ytterbium sheath is often made and other purposes channel separation; endoscope's tract road front end is with visual transparency protected or macromolecular material sealing; so just limited the active length of endoscope distal end; endoscope packs into behind the mirror sheath; the endoscope rear end must be connected locking with mirror bridge tip lock lens device; form endoscope's tract of sealing isolation, so limited the lock mirror position of endoscope rear end.Because different brands endoscope working portion length there are differences; if endoscope's tract length can not be adjusted; when endoscope's attaching mirror sheath; occur most probably that endoscope puts into that endoscope's tract front end puts in place and the rear end can not be locked lens device with Jing Qiao and is connected and puts in place; perhaps endoscope rear end and Jing Qiao lock lens device is connected and locks and situation that endoscope's tract front end object lens can not be pressed close to endoscope's tract front-end protection sheet; if and long visual transparency protected of the front end that probably pushes away of endoscope's active length; then can impact by the normal observing effect of endoscope, also may cause unexpected injury to the patient.
Granted publication number has disclosed a kind of disposal vesica urinaria examination mirror sheath for the Chinese patent of CN100569175C, this scheme provides can hold endoscope and operating theater instruments enters the dual pathways mirror sheath structure that inside of human body carries out diagnosis and treatment simultaneously, but this mirror sheath structure also has problems simultaneously, one of them is that minibridge (being Jing Qiao) is solid shape, non-telescoping adjustment, like this inconvenience of the endoscope of different operating length is connected with the mirror sheath in operation, then can impact by the normal observing effect of endoscope; In addition, the mirror bridge construction can not tighten with mirror sheath main body connecting portion location, rotates easily.
Summary of the invention
Problem to be solved in the utility model provides a kind of disposable endoscope mirror sheath with telescopic mirror bridge, can make the endoscope of different operating length be convenient to be connected with the mirror sheath, can solve simultaneously the mirror bridge construction can not tighten with mirror sheath main body connecting portion location, prevents that overall structure from rotating.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of disposable endoscope mirror sheath with telescopic mirror bridge, comprise endoscope's tract, mirror sheath main body and extension type Jing Qiao in the mirror sheath, endoscope tract rear end links to each other with extension type Jing Qiao by mirror sheath main body, and it is characterized in that: described extension type Jing Qiao is provided with groove and sealing ring; Be provided with spacing inserted sheet in the described groove; Be embedded with the hole clipping of blocking described spacing inserted sheet on the described mirror sheath main body.
Further, described hole clipping is square hole.
Further, described sealing ring is cushion rubber.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, extension type Jing Qiao inserts after the mirror sheath main body so that the distortion of spacing inserted sheet enters into embedded hole clipping.The realization product can not be extracted and return, and utilizes simultaneously the width of spacing inserted sheet that the axial location of extension type Jing Qiao and mirror sheath main body is fixed.Rotation that can not be random after the extension type Jing Qiao insertion.On extension type Jing Qiao, also has simultaneously cushion rubber.It is a certain amount of flexible to reach scalable with cushion rubber formation sealing after inserting.Extension type Jing Qiao is in case insert and can not return simultaneously.Product disposable also there is very large benefit.Such structure only needs mirror sheath main body and extension type Jing Qiao, adds O-ring seal, without other part, can realize can not extracting after extension type Jing Qiao inserts length adjustable, the purpose that restriction is rotated.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure:
1, extension type mirror bridge 2, groove 3, spacing inserted sheet
4, mirror sheath main body 5, hole clipping 6, sealing ring
The specific embodiment
As shown in Figure 1, this utility model provides a kind of disposable endoscope mirror sheath with telescopic mirror bridge, comprise endoscope's tract, mirror sheath main body 4 and extension type mirror bridge 1 in the mirror sheath, endoscope tract rear end links to each other with extension type mirror bridge 1 by mirror sheath main body 4, and it is characterized in that: described extension type mirror bridge 1 is provided with groove 2 and sealing ring 6; Be provided with spacing inserted sheet 3 in the described groove 2; Be embedded with the hole clipping 5 of blocking described spacing inserted sheet 3 on the described mirror sheath main body 4.Described hole clipping 5 is square hole.Described sealing ring 6 is cushion rubbers.
The work process of this example: during use, extension type mirror bridge 1 inserts after the mirror sheath main body 4 so that 3 distortion of spacing inserted sheet enter into embedded hole clipping 5.The realization product can not be extracted and return, and utilizes simultaneously the width of spacing inserted sheet 3 that extension type mirror bridge 1 and the axial location of mirror sheath main body 4 are fixed.Rotation that can not be random after extension type mirror bridge 1 inserts.On extension type mirror bridge 1, also has simultaneously cushion rubber.It is a certain amount of flexible to reach scalable with cushion rubber formation sealing after inserting.Realize extension type mirror bridge 1 in case insert and can not return, length adjustable, restriction is rotated.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to this utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
