Description

Soft endoscopic tissue reducing mechanism
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of soft endoscopic tissue reducing mechanism.
Background technology
Because of the development of endoscopic technic and tunneling technique, resectable disease is more and more under making scope, and resectable disease Stove is increasing, but often because focus greatly cannot be by limited cavity, such as at esophagus and cardia, pars oralis pharyngis, pyloric ostium, anus Mouth, tunnel face or the otch for actively opening a window so that the focus of excision cannot take out, then row operative treatment etc. again.So that interior When in face of larger focus, (particularly mesenchymoma, liomyoma) can cut off but because that cannot take out the various Minimally Invasive Surgeries of mirror, so that Suggestion patient directly carries out surgical operation.Surgical operation has the shortcomings that wound is big, risk is high, increase is painful.It is contemplated that Solving big focus makes it become small focus, so as to small focus can be taken out from limited pipeline.The present invention can also Cutting for other foreign matters in stomach huge gallstone, stomach is taken out.
The content of the invention
The technical problems to be solved by the invention are:A kind of soft endoscopic tissue reducing mechanism is provided, by big focus powder It is broken to become small focus, so that small focus can take out from limited pipeline, expand the indication of therapeutic endoscopy, it is to avoid portion Divide patient's surgical operation, patient is benefited.In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is:
A kind of soft endoscopic tissue reducing mechanism, including a steel wire and metal hose, the steel wire doubling and end to end simultaneously Together, the cross-section center of the metal hose is provided with groove, and the end of the metal hose is provided with two blades being placed in parallel, Steel wire after doubling is worn in the groove of the metal hose, and the doubling end of the steel wire is located at the end of the metal hose, The steel wire is also worn between two blades, and the distance between two described blades are adapted with the gauge of wire, Two blades of the blade are towards the outside of the metal hose.
The beneficial effects of the present invention are:The steel wire of doubling is slided in the groove of metal hose, and groove provides doubling The track that slides of steel wire, the slip to steel wire plays guide effect, and the steel wire of doubling is also located at two blades be arrangeding in parallel Between, two blades also limit the space of steel wire, make the movement locus of steel wire controllable;When gold is stretched out at the doubling end of steel wire Category flexible pipe, under steel wire in itself elastic reaction, steel wire deformation flare up is similar to oval wire loop, convenient by the disease in stomach and intestine Stove is placed in wire loop, when by steel wire to metal hose in pull, wire loop is slowly tightened up and entangles focus, when focal contact is arrived Blade, forms dissection positioned at two upper and lower blades of wire loop to focus respectively, realizes cutting off focus and crushes;Two The distance between described blade is adapted with the gauge of wire, then steel wire through two blades when be not susceptible to twisted phenomena, And blade is effectively exerted a force when cutting focus.
