Description

A kind of scope mucous membrane traction tongs

Technical field

The utility model relates to medical equipment field, specifically a kind of scope mucous membrane traction tongs.

Background technique

In recent years, with the gradually development of therapeutic endoscopy instrument continually developed with new technology, the major part of endoscopic detection Endoscopic excision may be implemented in early cancer and resection of submucosal tumor, and reaches the curative effect of surgical operation.Decollement under endoscopic mucosal (Endoscopic submucosal dissection, ESD) is the new treatment means occurred in recent years, and More early stage digestive system cancers disposable on scope can be cut off completely, eliminates for the good technology of potential applicability in clinical practice The pain of abdominal and the excision of organ.Compared with surgical operation, ESD wound is small, and patient is easy-tolerated, can be according to lesion Position, size, shape and organization type formulate reasonable individualized treatment scheme, not only can guarantee the thorough excision of tumour, but also energy Retain normal tissue and its function to the maximum extent, same patient is subjected to multiple ESD treatment, while can also once carry out more Site treatment.Decollement method is to utilize several special electric knives will on the basis of scope submucosal injections under endoscopic mucosal Mucous membrane removing where lesion and reach operating technology under the scopes of therapeutic purposes.In the prior art, it is enclosed with pincers road in interior mirror tube, Electric knife passes through pincers road with one piece of arrival lesion of shank, and lesion need to carry out submucosal injections in advance, to having carried out The pathological tissues of submucosal injections carry out incision processing, and pathological tissues are usually the softwares groups such as early cancer, polyp, liomyoma Knit, because it easily droops adhesion after lancing, on removing under subsequent mucous membrane have it is certain block influence, because of traction tongs in the prior art Locking device be the biggish lock handle of volume, lock handle device can not integrally from scope shank pincers road end be pierced by, lead Doctor has been caused not carry out the operation removed in traction using traction tongs and electric knife simultaneously, operative doctor need to be replaced frequently The tissue of incision is started and is then removed by surgical instrument；The prior art is tired without what is effectively drawn there are removing under scope mucous membrane It is difficult.

Utility model content

Against the above technical problems, the utility model technical effect to be achieved, which is to provide to have, facilitates operation, structure Simply, a kind of scope mucous membrane traction tongs that traction tongs can be detached from shank end under mucous membrane decollement.

In order to solve the above technical problems, a kind of scope mucous membrane traction tongs described in the utility model, including binding clip, protection Lid, motion bar, conduit, connecting line, the binding clip are fixedly connected on the inside of the protection cap by connecting shaft A, and the binding clip is logical It crosses connecting shaft B to connect with the motion bar, the motion bar is connect by connecting shaft C with described connecting line one end, and the company Wiring is placed in the conduit, and the tube at one end is fixedly connected with the protection cap, and the conduit other end is fixedly connected with Locking device, the locking device include that locking pedestal and lock nut, the locking pedestal are integrally connected by the fillet of screw and latch circle Composition is connect, the lock nut is made of nut and frustum of a cone integrally connected, the nut thread and the fillet of screw phase Match, the latch circle can be lock on the connecting line by the frustum of a cone.

Further, the locking device maximum outside diameter is less than 2.6mm.

Further, the other end of the connecting line is fixedly connected with pull ring.

Further, the latch circle is at least made of two panels latch.

Further, the latch at least there are two.

Further, the conduit is smooth material.

Compared with the prior art, the utility model has the following advantages:

1, the utility model is equipped with latch locking device in the conduit other end, which sticks case in binding clip When film pinches, lock nut can be rotated, as lock nut is toward the rotation of locking pedestal, latch gradually blocks connecting line, so After stop operating lock nut, for connecting line still in tension, i.e., binding clip, which is constantly in closure and pinches, takes state.

2, the utility model is less than 2.6mm, shank because changing original handle locking device, locking device maximum outside diameter Pincers road can be detached from pincers road end by traction tongs is whole, and traction tongs, which is then pinched always, to be taken pathological anatomy to set to stay in the body, mirror Electric knife can be placed in the road Shen Qian to be again introduced into vivo, worked at the same time with traction tongs and removed case group selvedge traction side, with This completes to remove operation under mucous membrane.

3, the utility model simple structure, it is easy to operate, the efficiency for removing operation under mucous membrane is improved, is also reduced simultaneously The operation difficulty of operative doctor.
