Description
Technical field
This utility model relates to a kind of high frequency electric knife for thecal cyst operation, belongs to technical field of medical instruments.
Background technology
In unit of medical institutions, treatment thecal cyst adopts the operation method of tradition (mechanical operation cutter) mostly, the weak point of traditional surgical approaches is that operating time is long, hemorrhage wound, for addressing this problem, mostly adopt the operation method treatment thecal cyst of high frequency electric knife at present in medical institutions.High frequency electric knife (high frequency electro surgical unit) be a kind of replace mechanical operation cutter carry out tissue cutting electrosurgical unit.When it contact with human body by the high-frequency high-voltage current that active electrode tip produces, tissue is heated, realize the separation of when injected organism tissue and solidify, thus playing the object of cutting and stopping blooding.The advantage of high frequency electric knife is that cutting speed is fast, haemostatic effect good, simple to operate, safe ready.Compared with adopting mechanical operation cutter with tradition, greatly can shorten operating time, reduce patient's blood loss and transfusion volume, thus reduce complication and surgery cost.But due to the handle of a knife of existing high frequency electric knife and the reasons in structure of cutter head, bother very much once handle of a knife or cutter head arbitrary appearance damage replacing are got up, simultaneously because the shape of existing cutter head is single, different operations can not be adapted to completely and use.
Summary of the invention
The purpose of this utility model is: provide a kind of structure simple once handle of a knife or the arbitrary appearance damage of cutter head can be changed it fast, and needs the high frequency electric knife for thecal cyst operation that can carry out bending to tip shapes conversion according to operation.
The technical solution of the utility model is:
For a high frequency electric knife for thecal cyst operation, comprise high frequency generator and cutter hub, cutter hub is connected with high frequency generator by connecting wire; It is characterized in that: described cutter hub is made up of handle of a knife, cutter head, stationary pipes, cutter head fixture and union joint, stationary pipes is provided with projection, stationary pipes is arranged in the centre bore of handle of a knife by raised thread, one end activity of stationary pipes is fitted with cutter head fixture, cutter head fixture is provided with union joint, union joint is threaded with handle of a knife, and described cutter head fixture is movably installed with cutter head, and cutter head fixture is connected with high frequency generator by connecting wire.
Lining is provided with between described union joint and cutter head fixture.
Described handle of a knife is tube.
On described handle of a knife, fixed cover is equipped with anti-skidding sleeve pipe, and the surface of anti-skidding sleeve pipe is provided with anti-slip veins.
Described cutter head is 7 shape, is bent into by steel wire, and the front end of cutter head is provided with cutting edge, and the end tail of cutter head is provided with installing ring.
Described cutter head fixture is made up of conical head and extension, conical head is provided with centre bore, the tail end of conical head is fixed with extension, extension is communicated with centre bore, extension is symmetrically arranged with installing hole, be movably set with connection bolt in installing hole, the conical surface of described conical head is provided with multiple expansion joint.
The utility model has the advantage of:
This high frequency electric knife being used for thecal cyst operation is because cutter head is by cutter head fixture, stationary pipes and union joint are arranged on handle of a knife, once handle of a knife or the arbitrary appearance damage of cutter head can be changed it fast, simultaneously because cutter head is bent into by steel wire, simple change can be carried out to it as required during operation, solve existing handle of a knife or the arbitrary appearance of cutter head to damage replacing and get up and bother very much, simultaneously because the shape of cutter head is single, the problem that different operations uses can not be adapted to completely, this high frequency electric knife structure being used for thecal cyst operation is simple, practicality is good, be specially adapted to thecal cyst operation use.

Detailed description of the invention
This high frequency electric knife being used for thecal cyst operation comprises high frequency generator (not shown) and cutter hub, and cutter hub is made up of handle of a knife 1, cutter head 2, stationary pipes 3, cutter head fixture 4 and union joint 5.Handle of a knife 1 is tube; On handle of a knife 1, fixed cover is equipped with anti-skidding sleeve pipe 12, and the surface of anti-skidding sleeve pipe 12 is provided with anti-slip veins.Skid to avoid gripping in operation process.
Stationary pipes 3 is provided with protruding 6, stationary pipes 3 is arranged in the centre bore of handle of a knife 1 by protruding 6 screw threads.One end activity of stationary pipes 3 is fitted with cutter head fixture 4.Cutter head fixture 4 is made up of conical head 7 and extension 8, and conical head 7 is provided with centre bore, the conical surface of conical head 7 is provided with multiple expansion joint 10.The tail end of conical head 7 is fixed with extension 8, and extension 8 is communicated with centre bore, and extension 8 is symmetrically arranged with installing hole, is movably set with connection bolt 9 in installing hole.
The periphery of cutter head fixture 4 is provided with union joint 5, and union joint 5 is threaded with handle of a knife 1.Union joint 5 pairs of cutter head fixtures 4 form parcel shape.Lining 11 is provided with between union joint 5 and cutter head fixture 4.
Cutter head fixture 4 is movably installed with cutter head 2.Cutter head 2 is in 7 shape, and be bent into by steel wire, the front end of cutter head 2 is provided with cutting edge, and the end tail of cutter head 2 is provided with installing ring 13.Cutter head 2 is inserted into extension 8 by the centre bore of conical head 7, is connected with connection bolt 9 by installing ring 13.Connection bolt 9 is provided with and connects wire 14, the other end connecting wire 14 is passed by the other end of stationary pipes 3 and is connected with high frequency generator.
It has been a position-limiting action that the end face of the conical head 7 of this high frequency electric knife cutter head fixture 4 is inserted in stationary pipes 3 at cutter head fixture 4, simultaneously owing to conical head 7 being provided with multiple expansion joint 10, and is provided with lining 11 between union joint 5 and cutter head fixture 4.Therefore, when cutter head 2 is installed, after union joint 5 is threaded with handle of a knife 1 and puts in place, under the cooperation of stationary pipes 3, lining 11 pairs of cutter head fixtures 4 form extruding, expansion joint 10 is shunk, thus cutter head 2 can be formed firm grip.
This high frequency electric knife structure is simple, practicality is good, because cutter head 2 is bent into by steel wire, can carry out simple shape change as required during operation to it, simultaneously by the cutting edge that cutter head 2 front end is arranged, under the state can interrupted at operation process high-frequency current, auxiliary cutting can be carried out to lesion tissue; Facilitate the operation of medical worker, solve existing handle of a knife or the arbitrary appearance of cutter head and damage replacing and get up and bother very much, simultaneously because the shape of cutter head 2 is single, the problem that different operations uses can not be adapted to completely, be specially adapted to thecal cyst operation and use.
