Abstract

The utility model discloses an endoscope external-arranged type powerful stone breaking device which comprises an endoscope body. A fixing sleeve which is tightly connected with the endoscope body in a sleeved and matched mode is arranged at the end of the endoscope body. A stone breaking tube sleeve is arranged on one side of the fixing sleeve and internally provided with a stone breaking tube tightly connected with the stone breaking tube sleeve in a clamped and matched mode. A cutting steel wire rope is arranged in the stone breaking tube. Teeth are arranged on the inner side of a working part of the cutting steel wire rope. The endoscope external-arranged type powerful stone breaking device is simple in structure and convenient to operate, and the thickness of the stone breaking device is free of strict limitation of a biopsy channel on the premise that the original use functions are not influenced; in addition, due to the design that the teeth are arranged on the working part at the front end of the cutting steel wire rope, the stone breaking force of a thick steel wire is enlarged; meanwhile, the endoscope external-arranged type powerful stone breaking device is not prone to deformation and not prone to slipping after stomach stone is sleeved, and the stability is improved; the stone breaking efficiency is improved, and the effective stone breaking effect can be achieved on the large and hard stomach stone.

Description

The powerful calculi breaking device of a kind of endoscope external

Technical field

This utility model relates to medical apparatus and instruments processing and manufacturing field, is specifically related to the powerful calculi breaking device of a kind of endoscope external.

Background technology

At present, still inserting the cutting gastrolith such as snare taking transendoscopic biopsy duct for the treatment of gastric calculus (gastrolithiasis) treats as main, but owing to being subject to the restriction in scope duct, the calculi breaking device of inserting is conventionally thinner, in cutting gastrolith process, cutting device is very easily out of shape, to such an extent as to the apparatus of distortion operates very difficult in continual cure process, in addition, the internal mirror front end of rubble apparatus that transendoscopic biopsy duct is inserted easily causes breakage.

Utility model content

This utility model object is to provide the powerful calculi breaking device of a kind of endoscope external, and it can solve existing problem in background technology effectively.

In order to solve existing problem in background technology, it comprises endoscopic main body, the end of this endoscopic main body is provided with and its fixed cover that closely socket coordinates, one side of this fixed cover is provided with rubble pipe box, in this rubble pipe box, be provided with the broken stone pipe coordinating with its tight clamping, in described broken stone pipe, be provided with cutting wire rope, the inner side of described cutting wire rope operate portions is provided with tooth.

Described tooth is the left and right setting of staggering.

In described rubble pipe box, be fixed with metal canula, the edge outward radial that this metal canula is positioned at cutting wire rope one end extends a circle and stops limit, the seam corresponding with limit only that concave out on the end face of described rubble pipe box, is provided with the broken stone pipe coordinating with its tight clamping in described metal canula.

Owing to having adopted above technical scheme, the utlity model has following beneficial effect: simple in structure, easy to operate, under the prerequisite that does not affect its original use function, make lithotrite thickness not be subject to the strict restriction in biopsy duct, and the front end operate portions of cutting steel wire have the design of tooth, making it thicker steel wire has increased the dynamics of rubble, meanwhile, not yielding, and entangle after gastrolith, be difficult for slippage, increase tool stability.Improve the efficiency of rubble, can to more greatly and harder gastrolith given play to effective rubble effect.

Brief description of the drawings

In order to be illustrated more clearly in this utility model, below in conjunction with accompanying drawing, embodiment is briefly described.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the partial structurtes schematic diagram of Fig. 1;

Fig. 3 is the decomposing schematic representation of this utility model medium stone pipe box.

Detailed description of the invention

For technological means, creation characteristic that this utility model is realized, reach object and effect is easy to understand, below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.

Referring to Fig. 1-2, this detailed description of the invention is to be achieved by the following technical solutions, it comprises endoscopic main body 1, the end of this endoscopic main body 1 is provided with and its fixed cover 2 that closely socket coordinates, one side of this fixed cover 2 is provided with rubble pipe box 3, in this rubble pipe box 3, be provided with the broken stone pipe 4 coordinating with its tight clamping, under the prerequisite that does not affect its original use function, make rubble pipe box 3 thicknesses not be subject to the strict restriction in biopsy duct, in described broken stone pipe 4, be provided with cutting wire rope 5, the inner side of described cutting wire rope 5 operate portions is provided with tooth 6, making it thicker steel wire has increased the dynamics of rubble, simultaneously, not yielding, and entangle after gastrolith, be difficult for slippage, increase its stability, improve the efficiency of rubble, can to more greatly and harder gastrolith given play to effective rubble effect.

Described tooth 6, for the left and right setting of staggering, is convenient to gastric gastrolith quick crashing.

Referring to Fig. 3, in described rubble pipe box 3, be fixed with metal canula 7, the edge outward radial that this metal canula 7 is positioned at cutting wire rope 5 one end extends a circle and stops limit 71, the seam 31 corresponding with stopping limit 71 concaves out on the end face of described rubble pipe box 3, in described metal canula 7, be fixed with broken stone pipe 4, can effectively prevent from bursting rubble pipe box 3 at operating process medium stone pipe 4.

Using method and principle thereof below in conjunction with accompanying drawing to technical scheme in this detailed description of the invention are further elaborated.

When use, first calculi breaking device is entered into patient's stomach according to conventional steps, after finding gastrolith, be enclosed within gastrolith by cutting wire rope 5, because common gastrolith surface is the calcareous duricrust of one deck, and kernel mostly is pledge decorating film matter, therefore can realize the object of broken gastrolith by slow twitch the cutting wire rope 5 of further tying tight, so larger if the gastrolith volume after fragmentation is appointed, can repeat previous step and proceed fragmentation, until be able to the external size of complete Self-discharged.

Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although this utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of the each embodiment technical scheme of this utility model.
