Description

The disposable lock locking structure of endoscope's sheath

Technical field

This utility model relates to a kind of medical apparatus and instruments, especially relates to the locking mechanism of a kind of endoscope sheath.

Background technology

In conventional cystoscope operating theater instruments and hysteroscope operation apparatus, be all to take the rustless steel operating theater instruments of non-once as main.And simultaneously stainless metal operating theater instruments due to cost and higher while of the cost also disposable apparatus of right and wrong, and in order to guard against cross infection, more clean disposible arises at the historic moment.Its feature is can be in order to avoid sterilization, not only health but also saved time, save the process of sterilization.Yet the greateset risk of disposable medical instrument is to be reused to cause infection, how to prevent and to avoid these disposable endoscope adnexaes to be reused by intentional or unintentional, be the new problem that current disposable new product faces.

Applicant has disclosed a kind of type self-destroyed lock lens device in patent 102293628A, but this version more complicated, inconvenient doctor's operation.

Summary of the invention

Problem to be solved in the utility model is to provide the disposable lock locking structure of endoscope's sheath, guarantees to be connected with endoscope and uses disposable endoscope adnexa to be reused problem.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

The disposable lock locking structure of endoscope of the present utility model sheath is that the principle by two compound ratchet wheels realizes, and two ratchets each other in the other direction.By control, lock the stroke of direction, when the rotation use that rotation cannot repeat cannot be continued in the stroke use back of locking.Product rotation signal step is referring to accompanying drawing 1, and product cannot rotate after unclamping locking, or only to rotate on a small quantity but can return.

Concrete structure is as follows:

The disposable lock locking structure of endoscope's sheath, comprises that the interface of mirror sheath, middle level cover, lock sleeve ,Jing Qiaoyu endoscope, middle level cover and lock mirror are enclosed within seam and are enclosed within Jing Qiaoshangjiang endoscope and lock; The interface of described Jing Qiaoyu endoscope is wide, the upper and lower narrow shape in two ends, left and right, has locating slot on interface; One end of mirror sheath is provided with location round pin; Middle level puts and is provided with discharge cock; There are two ribs one end of lock sleeve on circle, and the lock sleeve other end has alignment pin.

After locking, rotate normally 70-110 ° of interval, but be not limited to this number of degrees.

This patent is mainly that endoscope interface is locked, and is applicable to the endoscope of the different brands of same-interface.Above-mentioned interface shape is that endoscope and operating theater instruments are leading in the industry, as German Ka Ershituosi (storz) company designs employing the earliest.Other company follows storz company always all the time, and great majority all adopt the interface of this form, is used for matching with various operating theater instruments.Sight glass type does not generally adopt except larger peritoneoscope, laryngoscope, other be all suitable for as cystoscope, hysteroscope, nasal sinuses mirror, otoscope, knee arthroscope.

Concrete occupation mode refers to the description of embodiment.

Advantage and the good effect that the utlity model has are: the disposable lock locking structure of endoscope's sheath of this utility model design adapts to the feature of disposable products, can effectively prevent and avoid these disposable endoscope adnexaes to be reused by intentional or unintentional; Simultaneously simple in structure, be easy to produce in enormous quantities.

The specific embodiment

The disposable lock locking structure of endoscope's sheath, comprises that the interface A of mirror sheath 1, middle level cover 2, lock sleeve 3 ,Jing Qiaoyu endoscopies, middle level cover and lock mirror are enclosed within seam and are enclosed within Jing Qiaoshangjiang endoscope and lock; The interface 4 of described Jing Qiaoyu endoscope is wide, the upper and lower narrow shape in two ends, left and right, has locating slot 4A on interface; One end of mirror sheath is provided with location round pin; Middle level puts and is provided with discharge cock 2A; There are two rib 3A one end of lock sleeve 3 on circle, and the lock sleeve other end has alignment pin 1A.

Concrete use procedure is as follows:

First product interface section is put in the middle of lock sleeve, it is wide, narrow up and down that interface is two ends, left and right.Simultaneously there are two rib 3A one end of lock sleeve on circle, the shape of the lock sleeve insertion that conforms to Interface Shape during insertion.Inserting on rear port has locating slot 4A to have alignment pin 1A, alignment pin by locating slot, the product that will lock to be positioned at the mirror bridge portion of lock sleeve.After rotation, overlaps with interface, so the time coincidence of spiral rotating coincidence rotation 90 left and right, the interface that presses sight glass complete locking.

Before use, need discharge cock 2A to push over.Because discharge cock limits lock sleeve, before discharge cock is pulled to, product cannot be not in rotary moving.After discharge cock is opened.Now sight glass is locked into product and is put into, or is about to put into, and discharge cock is pushed into root.On discharge cock, have rotary locking cover, the helicla flute of now following on lock sleeve cooperatively interacts with location round pin 1A.Make lock sleeve by helicla flute, limit its displaced position when rotated, when rotation to two ribs cross, during 90 ° of left and right of displacement.Complete the rotation use angle of locking locking according to the size difference of product or variation to some extent.After product is once locked, rotate normally 70-110 ° of interval, but be not limited to this number of degrees.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to this utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
