Description
Technical field
The invention belongs to field of medical products, specifically a kind of novel single channel controllable type dripping bipolar coagulation.
Background technology
Bipolar coagulation is the most common hemostatic device of neurosurgery, is made of tweezer body and electrode tip holder, tweezer body tail end and electrode
Seat is connected, and the external table of tweezer has insulation rubber.Bipolar coagulation can carry out finer electric coagulation hemostasis to thin vessels and other structures,
Principle is to make protein coagulation, vessel sealing by heating, simultaneously because the blade insulation of bipolar coagulation, conducts electricity only between tweezer point
Stream, when coagulation, electric current is sharp from a tweezer point to an other tweezer, two tweezers point tissue by the fuel factor effect of electric current, play office
Portion stops blooding purpose, and the outer tissue of tweezer point it is few by or it is unaffected, and have protective effect to brain tissue.Bipolar coagulation, which also has, to be divided
The effects that from clamping.
Bipolar coagulation provides immeasurable effect to Cerebral surgery hemostasis, but in hemostasis there are still some not
The place of people's will to the greatest extent, for example in electric coagulation hemostasis, adhesion between brain tissue and tweezer point keeps hemostasis more difficult, or since adhesion adds
Reppear blood, have dripping bipolar in clinical application in recent years, but there is also drawback, such as speed of dropping water is difficult to control, when speed is slow from
Less than the effect of preventing adhesion, haemostatic effect is not good enough when speed is fast；Secondly, dripping device inputs water pipe on bipolar forceps top by one
It is divided into two and leads to tweezer point along tweezer body direction inside tweezer body respectively, has water outlet outflow in insulating layer and tweezer point inside, the water
The front end water outlet in channel is located at conductive active tip, there are adhesion plugging situation is more, in art frequent siphunculus, waste hand
The art time；Additional two water inlet pipes in bipolar coagulation upper end again increase the resistance and tweezer body weight of both sides tweezer tablet, when for operation
Between long patient, increase the gripping burden of patient, hand shaking can be caused for a long time, increase operation risk.
Invention content
To solve defect in the prior art, the object of the present invention is to provide a kind of novel single channel controllable type drip it is double
Pole coagulation controls speed of dropping water, prevents adhesion in art to mitigate tweezer body weight.
For achieving the above object, the present invention uses following technical scheme：
A kind of novel single channel controllable type dripping bipolar coagulation, including tweezer body I, tweezer body II, tweezer handle, weeper, single channel drop
Water pipe, water-supply-pipe, accurate flow velocity adjust water delivery device, limiter, electric wire；The upper front end of tweezer body I is provided with weeper, drips
Hole is connected by the single channel weep pipe that I inner wall of tweezer body is arranged with one end of water-supply-pipe, the water-supply-pipe other end and accurate flow velocity
Water delivery device is adjusted to be connected；Limiter is fixed on II middle part inner wall of tweezer body I and tweezer body, and single channel weep pipe passes through limitation
Device, limiter make single channel weep pipe folded closed when tweezer body I, tweezer body II open, and make list when tweezer body I, tweezer body II are closed
Channel weep pipe stretching, extension circulation.
Further, the tweezer body I is fixedly connected with tweezer body II by tweezer handle.
Further, the tweezer body I and II outer wall of tweezer body are equipped with antiskid thread.
Further, it is separately connected live wire on the tail portion of tweezer body I and tweezer body II.
Further, it is precision infusion set that the accurate flow velocity, which adjusts water delivery device,.
Compared with prior art, beneficial effects of the present invention are：1. bipolar coagulation of the present invention can accuracy controlling it is per minute go out
Water speed；2. bipolar coagulation of the present invention is supplied water using side tweezer body single channel, mitigate tweezer body weight, is convenient for surgical procedure；3.
The tweezer body front end weeper of bipolar coagulation of the present invention is located at the side tops Nie Jian, and two tweezer point adhesions in art is effectively prevent to block water outlet
Channel.

Specific implementation mode
Below in conjunction with specific implementation mode, the present invention will be further described.
A kind of novel single channel controllable type dripping bipolar coagulation, including tweezer body I 1, tweezer body II 2, tweezer handle 3, weeper 4,
Single channel weep pipe 5, water-supply-pipe 6, accurate flow velocity adjust water delivery device 7, limiter 8, electric wire 9；The upper front end of tweezer body I 1 is set
It is equipped with weeper 4, weeper 4 is connected by the single channel weep pipe 5 that I 1 inner wall of tweezer body is arranged with one end of water-supply-pipe 6, defeated
6 other end of water pipe adjusts water delivery device 7 with accurate flow velocity and is connected；Limiter 8 is fixed on II 2 middle part inner wall of tweezer body I 1 and tweezer body
On, single channel weep pipe 5 passes through limiter 8, and limiter 8 used is identical as the existing structural principle of bipolar coagulation limiter, limit
Device 8 processed is made of pipe clamp I 11 and pipe clamp II 12, and pipe clamp I 11 is fixed on I 1 middle part inner wall of tweezer body, and pipe clamp II 12 is fixed on and manages
Block on I 11 corresponding tweezer body, II 2 middle part inner wall, single channel weep pipe 5 sequentially passes through pipe clamp I 11 and pipe clamp II 12, limiter 8
Make single channel weep pipe folded closed when tweezer body I 1, tweezer body II 2 open, so that single channel is dripped when tweezer body I 1, tweezer body II 2 are closed
Water pipe stretching, extension circulation；Tweezer body I 1 is fixedly connected with tweezer body II 2 by tweezer handle 3, and tweezer body I and II outer wall of tweezer body are equipped with antiskid thread
10, live wire 9 is separately connected on the tail portion of tweezer body I and tweezer body II, accurate flow velocity adjusts water delivery device 7 and uses precision infusion set,
Such as Exadrop precision infusion sets.
When surgical procedure, by precision infusion set can accuracy controlling it is per minute go out water speed, go out according in operative site, art
The needs such as blood situation accurately adjust weeper speed of dropping water, and the weeper through I front end of tweezer body is discharged is imitated with reaching good hemostasis
Fruit, only I side tweezer body single channel of tweezer body supply water, mitigate tweezer body weight, be convenient for surgical procedure, are carrying out operating process for a long time
Operation when, the gripping resistance of patient's thumb and index finger can be saved, keep operation more accurate；The weeper of I front end of tweezer body is located at tweezer
Sharp upper end solves the problems, such as that existing bipolar coagulation weeper is discharged on the inside of tweezer point and easily leads to adhesion blocking weep pipe, effectively
Prevent two tweezer point adhesion in art.
