Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to the bipolar coagulation forceps for blood coagulation in surgical operation.
Background technology
Bipolar coagulation was just brought into use as far back as 1940, and within 1966, bipolar coagulation is applied to microsurgery by yasargil, for the Blood clotting that discharges to blood capillary.Its operation principle is for be connected to electrocoagulator main frame by tweezer wire, forceps tips clamps blood outlet, and electrocoagulator discharges electric current, between two tweezer points, form loop, there is provided high-frequency electrical energy to lesion tissue tissue, make the dehydration degeneration of the blood vessel between bipolar forceps two ends and solidify.Because its electric current only flows through between two tweezer points, burn so can not cause other positions, be suitable for very much all kinds of microsurgery.There being normal saline blood and cerebro spinal fluid to deposit in case, still anastalsis can be played.
Owing to carrying out coagulation at the most advanced and sophisticated position of electric coagulation forceps, so the conduction of tweezer point and radiating effect are very crucial, existing electric coagulation forceps is in order to ensure most advanced and sophisticated heat-conductivity conducting, take into account again supportive and the aeroelastic requirements of holding end, therefore tweezer body is all with metal forming, mainly adopts rustless steel, pyrite or titanium alloy to make.Fix spray insulation resin after the tweezer tablet molding of left and right, traditional manufacturing technique is outmoded, and flow process is complicated, manual production, and volume production difficulty, the production cycle is long and quality is uncontrollable.
In current neurosurgery coagulation process, when using traditional electric coagulation forceps, the tissue after blood coagulation can be bonded on tweezer point in coagulation process, when removing tweezers, the tissue just having completed blood coagulation can be again impaired, and whether adhesion is directly connected to the quality of surgical effect.Bipolar coagulation forceps in the market, comprises disposable bipolar coagulation forceps, reusable bipolar coagulation forceps, all there is the adhesion problems of tweezers and tissue in operation process.Have the method for technology silver coating at present to reduce adhesion, but the time is long, silver layer can come off and produce adhesion eschar, therefore, develops a kind of truly feasible adhesion, the electric coagulation forceps that can solve the problem, and is the important topic of advanced operating theater instruments development.
Summary of the invention
The object of the invention is the deficiency that risk and processing technology in order to overcome existing electric coagulation forceps adhesion is complicated, a kind of adhesion bipolar coagulation forceps is provided, this electric coagulation forceps can not only have good preventing adhesiving effect, and conveniently manufactures, thus well solves the problem of adhesion and complex process.
To achieve these goals, technical solution of the present invention is as follows:
