Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, a kind of retracting type anti-acupuncture low temperature cutting ablating electrode, is tungsten alloy including joystick 3, instrumentation tubes 1 and tungsten pin 2(tungsten pin 2 material, and the superelevation fusing point (more than 3400 DEG C) by tungsten makes tip height heat-resisting.null)，Joystick 3 afterbody connects attraction corrugated tube 8，Corrugated tube 8 is attracted to be connected with taking out negative pressure device，Joystick 3 is internal is provided with PC plate，Joystick 3 surface is provided with TURP button 4、Coagulation button 5 and slide switch 6，TURP button 4 and coagulation button 5 are connected with PC plate respectively，PC plate is connected with external power source by wire 7，Instrumentation tubes 1 runs through whole joystick 3 and joystick 3 is stretched out in front end、Rear end connects with attracting corrugated tube 8，Instrumentation tubes 1 two ends are canned paragraph (9 and 10)、Centre is glissile segment 11，Glissile segment 11 canned paragraph (9 and 10) with two ends respectively is nested together，In tungsten pin 2 is located at instrumentation tubes 1 and be fixed on glissile segment 11，Glissile segment 11 is provided with push button 13，Push button 13 is connected with slide switch 6，Slide switch 6 slide anteroposterior can drive tungsten pin 2 syringe needle fully extended or retraction instrumentation tubes 1 front end.Tungsten pin 2 shank afterbody is reserved with a segment distance from joystick 3 afterbody, is available for tungsten pin 2 shank and slidably reciprocates, the length (tungsten pin 2 syringe needle is positioned near instrumentation tubes 1 front end when being fully retracted) exposed when this distance length is more than or equal to tungsten pin 2 fully extended instrumentation tubes 1.
During operation, take out negative pressure device pass sequentially through attraction corrugated tube 8 and instrumentation tubes 1 take operation smoke in real time away, it is therefore prevented that infect, beneficially operation is smoothed out；When pushing away before slide switch 6, tungsten pin 2 protracts therewith, and during slide switch 6 post-tensioning, tungsten pin 2 bounces back therewith and can be completely retracting in instrumentation tubes 1, it is therefore prevented that needle pricks surgical staff, and ensure needle point not with other article contacts, keep needle point sanitation and hygiene；Joystick 3 is stretched out in instrumentation tubes 1 front end, increases the length of tungsten pin 2, expands the opereating specification of tungsten pin 2, and suitable small space operates.
In the present embodiment, tungsten pin 2 needle point is polished, and tungsten pin 2 shank is provided with one layer of insulant.Tungsten pin 2 needle surface high polish, decreases operation smoke and produces, and does not sticks, not charred tissue, burn tissue when insulant can prevent needle point from going deep into, and protective tissue is injury-free, has more invasive, little to tissue stimulation damage.
In the present embodiment, insulant is heat-resistant polymer.Heat-resistant polymer is tough and tensile solid and has high dielectric strength, makes tungsten pin 2 shank SI semi-insulation highly effective.
As shown in Figures 1 to 4, TURP button 4 and coagulation button 5 are located at joystick 3 end face, and slide switch 6 is located in the straight line draw-in groove of joystick 3 side.
As shown in Figures 1 to 4, tungsten pin 2 is divided into elongated tungsten pin 2 and short tungsten pin 2, a length of 60-350mm of shank of elongated tungsten pin 2, and the shank corresponding instrumentation tubes of a length of 30-60mm(1 of short tungsten pin is also classified into elongated and short).It is respectively completed superficial part by the tungsten pin 2 of assembling different model to perform the operation and deep operation.
The instrumentation tubes 1 front end mouth of pipe has two types, and one is reducing (as shown in Figures 1 to 4), and another kind is diagonal cut joint (as shown in Figure 5).When smog drawn by needs, the instrumentation tubes 1 front end mouth of pipe uses diagonal cut joint, expands absorption scope, improves and draws effect, and when need not draw smog, the instrumentation tubes 1 front end mouth of pipe uses reducing, outside preventing tungsten pin 2 to be exposed to.
In the present embodiment, the long 3mm of tungsten pin 2 needle point, diameter 5 microns (can also be thinner).Needle point is elongated can keep sharp.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted, and all these modifications and variations all should be belonged to the protection domain of this utility model claims.
