Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of tear-away tissue holder and method of work thereof.
Background technology
Digestive endoscopy is a kind of diagnosis and treatment mode grown up gradually mid-term in 20th century, and wherein utilizing metal clip to stop blooding and closing perforation is use technology comparatively widely at present.Under endoscope's direct-view, use metal clip to press from both sides close bleeding part, substantially increase safety and the cure rate of digestive tract hemorrhage.When closed perforation, determine according to the size of perforation the quantity using metal clip, usually for little perforation, use several metal clip to close perforation.Relate to large perforation, then need multiple metal clip to close gradually.
In current endoscope body, closing device adopts the mode of extrusion tissue's vascular compression to reach hemostasis object, the metal clip usually slippage because patient's coat of the stomach is wriggled in clinical practice, and once can only discharge one piece of metal clip, taking-up is needed to recharge after having discharged, add the difficulty relocated, extend operating time.
But traditional absorbable tissue clamp has following shortcoming:
1) what absorbable tissue clamp clamp end extended to form locks tooth in tube chamber closedown difficulty, need good means skill, fully could be separated and need to press from both sides the tissue closed, if block in a organized way and lock tooth in, then be difficult to closedown and lock tooth in, also easily cause clamp to damage, affect the recovery of human body;
2) due to absorbable tissue clamp with need press from both sides the contact position closing tissue and be smooth surface, therefore, when folder is closed and folder close after through often tissue holder being caused to close the phenomenon of tissue landing from folder.
Disclosed patent name: chamber mirror absorbable tissue clamp, application number is: 200520051725.X, only comprises clamp and latch hook portion, and latch hook portion is located on the lateral surface of clamp opening, latch hook portion comprises and penetrates hook and hook, penetrates hook and the hook corresponding upper/lower terminal being arranged at clamp respectively.This utility model only increase make use of can penetrate tissue penetrate hook, thus can be used for pressing from both sides closing and need to press from both sides the tissue site that closes, operate easier.
Disclosed patent name: based on closing device in the body of the band running fire metal clip of endoscope, application number: 201310227491.9, comprise handle, sheath pipe and operate portions that order is connected, operate portions wherein comprises a sheath, and is arranged on pushing away seat, be multiplely arranged on metal clip in sheath cavity and a nipper in sheath cavity.The present invention uses nipper to capture destination organization, then closes from nipper inside release metal clip.Because metal clip is provided with multiple, the socket of multiple metal clip head and the tail is connected, and can realize the running fire of metal clip, and can realize accurate location; Close again after metal clip puncturing tissue, difficult drop-off, reliable for effect.
Summary of the invention
In order to solve the problems referred to above that prior art exists, the invention provides a kind of tear-away tissue holder and method of work thereof, in the treatment of intestinal endoscopy, closed hemostasis and tissue ablation.
The technical solution adopted in the present invention is: a kind of tear-away tissue holder, comprises clamp and release; Described clamp is formed primarily of intermediate plate, closed release ring and chuck, and described intermediate plate is fixedly mounted on the front end of chuck, and described closed release ring set is connected on chuck, and the rear end band of described chuck is fluted; Described release comprises elastic hose and flexible axle, and described flexible axle is positioned at elastic hose, and the concrete structure of described flexible axle is: be the conehead of bullet foremost, ining succession after conehead has elastic steel wire, is fixedly connected with push rod after steel wire; Can be connected between the described groove of chuck rear end and the conehead of the bullet of flexible axle.
As optimization: also comprise holder, described clamp is normally placed in holder, and described holder is that plastics are made.
As optimization: described intermediate plate is band tooth elastic clip.
As optimization: described intermediate plate is rustless steel intermediate plate.
As optimization: the length of described intermediate plate is 2.6-3.4mm.
As optimization: the diameter of described elastic hose is 2.2-3.8mm.
The method of work of described tear-away tissue holder, comprises the steps:
1) upper folder: the flexible pipe of release is pushed in holder by push rod, when the conehead of flexible axle inserts the groove of chuck, conehead by back-off, thus makes flexible axle and clamp fixedly be connected;
2) get folder: then back pull flexible axle, the intermediate plate originally opened is closed in flexible pipe gradually, clamp is separated with holder;
3) capture: clamp is entered intracavity by the admittance of intestinal mirror, when arriving intestinal inner disease foci position, promote flexible axle gently, the resilience due to intermediate plate makes intermediate plate eject in closed release ring to open, when jaws aims at lesion tissue, tension flexible shaft steel wire is until intermediate plate clamping lesion tissue closes;
4) closedly to come off: after intermediate plate is closed and put in place, then continue back to pull at, after pulling force acquires a certain degree, the conehead of flexible axle is separated with the groove of chuck, makes clamp stay in intestinal, extracts release out.
Beneficial effect of the present invention is: in the treatment of intestinal endoscopy, for closed hemostasis and tissue ablation.Can directly be used for pressing from both sides closing needs to press from both sides the tissue site closed, and does not need too much chorista, can tackle acute hemorrhage, easy and simple to handle, and can effectively prevent from pressing from both sides the phenomenon organizing disengaging in closed procedure.Concrete advantage is as follows:
1, intermediate plate and the closed elastic hose discharged in ring and release cooperatively interact, and have the function automatically discharging and open and locate, can press from both sides quick and precisely, easily and close tissue, without the need to too much operation.
Between the conehead of 2, the groove of chuck rear end and the bullet of flexible axle, only need when the conehead of flexible axle insert the groove of chuck, conehead, automatically by back-off, makes flexible axle and clamp fixedly be connected; And both needing when being separated, only needing to apply certain pulling force can separate, this easily to break the separate design come off be rarely found in existing tissue holder, belongs to the quantum jump in this field, have considerable prospect of the application.
3, the flexible axle in release is connected with elastic steel wire, can carry out telescopic moving as required at any time, increases controllability and the harmony of flexible axle, is the unexistent another spotlight of existing tissue holder.
