CN203328756U - Closing instrument with continuously-applied metal clips for endoscope - Google Patents

Abstract

The utility model discloses a closing instrument with continuously-applied metal clips for an endoscope. The closing instrument comprises a handle, a sheathing tube and a working portion, wherein the working portion comprises a protective sleeve, a push base arranged in the cavity of the protective cover, a plurality of metal clips arranged in the cavity of the protective cover, and a nipper. According to the closing instrument with the continuously-applied metal clips for the endoscope, the nipper is used for grabbing an objective tissue, and then the metal clips are pushed out of the nipper to conduct closing. Due to the fact that the metal clips are connected end to end in a sleeved mode, continuous application of the metal clips can be achieved, and precise position can be achieved. The metal clips conduct closing after puncturing the tissue, and are not prone to falling off and reliable in effect.

Description

The closed apparatus of endoscope-use band running fire metal clip

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of closed apparatus of endoscope-use band running fire metal clip.

Background technology

The digestive tract hemorrhage sickness rate is high, and change of illness state is fast, and amount of bleeding the greater can be because of the peripheral circulatory failure threat to life.Digestive endoscopy is a kind of diagnosis and treatment mode grown up gradually mid-term in 20th century, and wherein utilizing metal clip hemostasis and closed perforation is the technology comparatively widely of using at present.Under endoscope's direct-view, use the metal clip folder to close bleeding part, greatly improved safety and the cure rate of digestive tract hemorrhage.When closure is bored a hole, determine to use the quantity of metal clip according to the size of perforation, usually for little perforation, use several metal clips closed to bore a hole.Relate to large perforation, need a plurality of metal clips closed gradually.

Current endoscope adopts the mode of extrusion tissue's vascular compression to reach the hemostasis purpose with closing device in body, the usually slippage because patient's coat of the stomach is wriggled of metal clip in clinical practice, and once can only discharge one piece of metal clip, need after having discharged to take out and recharge, increase the difficulty relocated, extended operating time.

The specific embodiment

Referring to Fig. 1, coordinate referring to Fig. 2, Fig. 3, Fig. 4, the closed apparatus of endoscope-use band running fire metal clip of the present utility model, comprise handle 3,sheath pipe 2 and operate portions 1 that order is connected, operate portions 1 wherein comprises:

Onesheath 11, be provided with the cavity of axial perforation in it;

One is arranged on and pushes awayseat 12 in the sheath cavity, and this pushes awayseat 12 rear ends and pushes away silk 4 by one and be connected with handle 3, and operating grip pushes away silk and can promote to move forward.

A plurality ofmetal clips 13 that are arranged in the sheath cavity, a plurality of metal clips are socketed connected from beginning to end, its last metal clip with push awayseat 12 sockets and be connected.

Onenipper 14, this nipper rotatably is connected with the front end of sheath, and is connected with handle by twowire drawings 5, and operating grip pulls wire drawing can make the nipper closure;

Cooperation is referring to Fig. 6, andmetal clip 13 integral body in this utility model are the U-shaped structure of both sides symmetry, comprises U-shapedbottom 131, and theflap 132 sequentially extended along both sides, U-shaped bottom,thick arm 133 andmicrobrachia 134; The U-shaped bottom of previous metal clip may be stuck between two microbrachias of a rear metal clip, and is pressed on two microbrachias of a rear metal clip by two flaps of previous metal clip.Cooperation is referring to Fig. 7, and theseat 12 that pushes away in this utility model is provided with aU-shaped socket 121, and the U-shaped bottom of described metal clip can be inserted in this U-shaped socket, and by two flap stop bits.Twomicrobrachias 134 ofmetal clip 13 are respectively crooked to the inside arc, and can be crooked in opposite directions under external force, after two microbrachias bending simultaneously, 90 degree, realize closed.

Cooperation is referring to Fig. 5, and thenipper 14 in this utility model consists of symmetrically arranged twocalipers 141 and twoclamp handles 142, and clamp handle is fixedly connected on the rear end of caliper.The front portion ofsheath 11 is provided withminor axis 111, andclamp handle 142 rotatably is connected withminor axis 111 byaxis hole 1421;Clamp handle 142 rear ends are connected with an end ofwire drawing 5, and the other end ofwire drawing 5 is connected with handle, and operating grip pulls wire drawing to make the minor axis rotation of clamp handle along sheath, thereby realize the closure ofnipper.Caliper 141 is provided with left and right two row'spincers teeth 1411,1412, and centre is provided withgroove 1413, and front end is provided with choppingblock 1414, and this chopping block is provided with aduncate arcwall face, andgroove 1413 forms the passage of metal clip, and choppingblock 1414 forms the guide function body that makes the metal clip closure.

But operating process principle accompanying drawings of the present utility model is as follows:

During use, at first utilizenipper 14 to capture destination organization, now twowire drawings 5 synchronously pull back, and drive nipper 14 closures.

Then, from the interiorrelease metal clip 13 ofnipper 14, and complete closure.Concrete transmittance process is, pushes away silk 4 and drives and push awayseat 12, pushes awayseat 12 and drives last metal clip, then drive to the current metal clip discharged successively.Metal clip is by from the interior release ofsheath 11, nipper 14 gripping destination organization now,metal clip 13 enters in thegroove 1413 of nipper and thrusts destination organization, finally prop up choppingblock 1414, continue to push hard and push away silk 4, make after the crooked closures ofmicrobrachia 1411,1412 arcwall faces along choppingblock 1414 of frontend metal clip 13 to complete to discharge.If when nipper captures destination organization, effect is undesirable, again capture after can making it open, again by joystick 3 locking nippers, guaranteed to capture the accuracy of destination organization after confirmation.

This utility model adopts the principle of similar stapler, therefore can reach the purpose of discharging continuously many all-metal folders, and closure effect is reliable.In addition, nipper possesses repeatedly the function opened and closed, and has made up current endoscope and only can discharge one piece of metal clip, weak point that grasping force is little with metal clip.
