Description
Technical field
This utility model relates to a kind of mucosa incision knife, belongs to technical field of medical instruments.
Background technology
At present, in medical scope field, for Alimentary tract disease tissue, adopt Endoscopic submucosal dissection for rectal, by incision knife, pathological tissues place mucosa is peeled off the object reaching treatment.Mucosa detacher is usually used in purposes such as cutting pathological changes sub-mucosal tissues or polyp etc., is clinical conventional apparatus.Conventional mucosa incision knife complicated operation, operating time is long, and risk is high, higher to the technical requirement of clinician, causes this technology to use by popularity.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, a kind of mucosa incision knife is provided, when it not only cuts and peels off sub-mucosal tissues focus under scope, and advance convenient direct during cutting, make operation more convenient, greatly reduce the operation easier of doctor, save the time.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of mucosa incision knife, and it comprises:
Outer jacket member;
Electricity circle, the head of described electricity circle is class triangular structure, for peeling off mucosa and being arranged on the cutting electricity silk of electricity circle head front end and being engaged on the supporting wire cutting electric silk both sides and surrounding, and described supporting wire is arranged with insulating barrier;
Slip ring, described slip ring is arranged on outer jacket member, and described slip ring can move axially relative to outer jacket member, and slip ring is provided with electrode plug;
Drag-line, drag-line can axially movably be inserted in outer jacket member, and one end of described drag-line is enclosed with electricity and is connected, and the electrode plug on the other end of drag-line and slip ring is electrically connected.
Further, described outer jacket member comprises pipe sheath, protecting pipe, turncap and core bar, and pipe sheath is connected with one end of protecting pipe, and the other end of protecting pipe is connected with core bar by turncap.
Convenient in order to cut further, cutting is led more accurate, the cutting electricity silk of electricity circle is the arcuate structure to drag-line lateral bend.
After have employed technique scheme; under the direct-view of endoscope; electricity circle protruded tube sheath front end under the manipulation of slip ring; electricity circle is designed with exposed cutting electricity silk; cut electric silk and press close to pathological tissues; cut electric silk and connect high frequency electric source by electrode plug; promote the electric silk of cutting to cut and organize; progressively pathological tissues is peeled off, supporting wire has and has insulating barrier, normal structure can be protected not to be damaged; after adopting this utility model; make operation more convenient, greatly reduce the operation easier of doctor, save the time.
