Description

Application method of digestive tract endoscope closing clamp

Technical Field

The invention relates to a method for using a closing clamp of an digestive tract endoscope.

Background

The existing OTSC closing clamp is an alloy harrow-shaped clamp which is arranged in a release sleeve at the front end of an endoscope in advance, and a special grasping forceps is used for pulling tissues around a lesion into a cap or sucking the tissues around the lesion and the mucous membrane into the cap by negative pressure suction, and then a matched rotary trigger system is used for occluding the tissues together by the harrow-shaped clamp, so that the functions of stopping bleeding and sealing perforation are achieved. OTSC can bite more tissue than conventional titanium clips, effectively closing a larger incision. However, OTSC closure clips suffer from the following drawbacks: if the OTSC closing clamp bites tissues, the taking-out needs to take out a large amount of force, namely the taking-out is inconvenient, especially when the occlusion is unsatisfactory, the defect of inconvenient taking-out of the OTSC closing clamp is particularly remarkable, and a certain trouble is brought to the operation.

Disclosure of Invention

The invention provides a method for using a closing clamp of an digestive tract endoscope, which overcomes the defects of the prior art in the background technology.

The technical scheme adopted for solving the technical problems is as follows:

the utility model provides a closed clamp of alimentary canal scope, it includes an elasticity closure anchor clamps and an elastic ring that can cut, and this elasticity closure anchor clamps includes a fixed ring and the fixed ring interval arrangement of ring and the many elastic tooth piece of one end and this fixed ring rigid coupling, and the other end of these elastic tooth pieces forms the closed throat that is used for closed alimentary canal wound, and this closed throat can outwards energy storage prop up or inwards release can tighten up, and this elastic ring detachably elasticity beam dress is in the lateral wall outside of these elastic tooth pieces and forms inwards concentrated constraint power to this elastic tooth piece.

In one embodiment: the elastic tooth plates are enclosed to form a hollow revolving body with upper and lower openings, and the revolving body is small in two ports and large in middle belly.

In one embodiment: the elastic tooth piece is in a shape of' >.

In one embodiment: the elastic ring is an elastic band.

The application method of the digestive tract endoscope closing clamp comprises the steps of assembling the closing clamp with a transparent cap at the front end of an endoscope: inserting a transparent cap at the front end of the endoscope from the upper end of a fixed circular ring of the closing clamp to enable the closing clamp to elastically encircle the transparent cap, and binding the elastic ring on the outer side wall of an elastic tooth piece of the closing clamp;

in one embodiment: further comprising releasing the closure clip: after the transparent cap sucks the tissue around the wound into the transparent cap, the closing clamp is pushed forward and separated from the support of the transparent cap through the OTSC release system, and simultaneously the closing shrinkage mouth of the closing clamp closes the wound under the action of the energy release tightening force and the tightening force of the elastic ring.

In one embodiment: including removal of the closure clip: the elastic ring is sheared off, and the closing clamp is taken out from the wound.

Compared with the background technology, the technical proposal has the following advantages:

1. the closing shrinkage mouth formed by the plurality of elastic tooth sheets is used for outwards accumulating energy to prop up or inwards releasing energy to tighten the closing wound, and the elastic tooth sheets are subjected to further nailing by the inwards concentrated binding force formed by the elastic ring, so that the closing clamp forms good anastomosis and effective closing on the wound.

2. After the closure clip is clamped on the occlusal tissue, the closure clip can be easily taken out by cutting off the elastic ring, and the operation is simple and convenient.

3. The closing clamp provided by the invention has the advantages of simple, ingenious and novel structure and low manufacturing cost.

Detailed Description

Referring to fig. 1, an enteroscope closing clamp 100 includes an elastic closing clamp 10 and a shearable elastic ring 20, the elastic closing clamp 10 includes a fixed ring 11 and a plurality of elastic teeth 12 disposed around the fixed ring 11 at intervals, one end of the elastic teeth 12 is fixedly connected with the fixed ring 11, the other end of the elastic teeth 12 forms a closing constriction 121 for closing an enteron wound, the closing constriction 121 is specifically an annular rake tooth formed by the other end of the elastic teeth 12, the closing constriction 12 can be outwardly stored for expanding or inwardly releasing for tightening, and the elastic ring 20 is detachably and elastically bound on the outer side wall of the elastic teeth 12 and forms an inwardly concentrated binding force for the elastic teeth 12.

The elastic tooth plates 12 are enclosed to form a hollow revolving body with upper and lower openings, and the revolving body is small in two ports and large in middle belly. In this embodiment, the elastic tooth sheet is ">".

Preferably, the elastic ring 20 is a rubber band, and is easily sheared with a sufficient elastic binding force.

The application method of the digestive tract endoscope closing clamp comprises the following steps:

assembly of the closure clip 100 with the endoscope front transparent cap 200: referring to fig. 2, a transparent cap 200 at the front end of the endoscope is inserted from the upper end of a fixed ring 11 of the closing clip 100 to enable the closing clip 100 to elastically encircle the transparent cap 200, and an elastic ring 20 is bundled on the outer side wall of an elastic tooth sheet 12 of the closing clip 100;

release of the closure clip: referring to fig. 3, after the transparent cap sucks the tissue around the wound into the transparent cap, the closure clip 100 is pushed forward and separated from the support of the transparent cap by the OTSC release system, and the closure constriction 121 of the closure clip closes the wound under the action of the release tightening force and the tightening force of the elastic ring 20.

Removal of the closure clip: the elastic ring 20 is sheared and the closure clip is removed from the wound. The cutting process can be performed under the endoscope, through the biopsy channel, the elastic ring is cut by using special scissors, and then the closing clamp is in a loose state, so that the needle can be taken out.

The invention uses the closing shrinkage mouth 121 formed by a plurality of elastic tooth sheets 12 to store energy outwards and spread or release energy inwards to tighten the closing wound, and uses the elastic ring 20 to form the binding force concentrated inwards to the elastic tooth sheets 12 to further staple the wound, so that the closing clip 100 forms good anastomosis and effective closing to the wound. After the closing clip 100 is meshed with tissues, the closing clip 100 can be easily taken out by shearing the elastic ring 20, so that the operation is simple and convenient, and the operation difficulty of a surgeon is reduced. The closing clamp provided by the invention has the advantages of simple and novel structure and low manufacturing cost.

The foregoing description is only illustrative of the preferred embodiments of the present invention, and therefore should not be taken as limiting the scope of the invention, for all changes and modifications that come within the meaning and range of equivalency of the claims and specification are therefore intended to be embraced therein.
