Abstract

An efficient microwave scalpel includes a handle and a waveguide tube; an outer conductor is arranged at a transmitting terminal at the front end of the waveguide tube; arc cuts are formed on two sides of the outer conductor, form the upper part and the lower part of a U-shaped groove, and are respectively taken as an upper external pole and a lower external pole; an insulating medium and an innerconductor are sequentially arranged in the outer conductor; the end surface of the inner conductor is fixedly connected with an output tool bit; and the output tool bit is higher than and parallel tothe tip connecting line of the upper external pole and the lower external pole. The efficient microwave scalpel is characterized in that the upper external pole, the lower external pole and the output tool bit at the middle are all increased to 5-10 mm, and an output tool bit blade and a lower external blade are respectively arranged on the output tool bit and the lower external pole and form anarc sliding cutter. The strength of the microwave emission field thereof is increased by 70%, the cutting speed and the vessel solidifying and closing speed are increased by 70%, and the operation time can be shortened by more than 50%. At the same time, the scalpel for cutting has the functions of solidifying and killing incisal edge cancer cells, reducing the tumorous incisal edge transfer, andimproving the therapeutic effect of the operation.

The technical solution of the utility model is achieved in that a kind of efficient microwave scalpel, comprise: handle, waveguide, the transmitting terminal of waveguide front end is provided with outer conductor, the outer conductor both sides be provided with curved incision form U-lag on, under be respectively the outer utmost point, the following outer utmost point, set gradually dielectric in the outer conductor, inner wire, the affixed output cutter head of inner wire end face, its output cutter head is higher than and is parallel to, following outer pole tip end line, the described outer utmost point, the outer utmost point and intermediary output cutter head rise to the 5-10 millimeter down, and the utmost point is provided with output cutter head blade respectively outside the output cutter head reaches down, following outer utmost point knife-edge camber sliding cutting cutter.

Describedly go up the outer utmost point, descend the outer utmost point and intermediary output cutter head all with the centrage of the waveguide angle α that is tilted to the left, angle α is 5-25 °.

The described outer utmost point, down outer extremely concordant being on the waveguide vertical line.Described output cutter head blade is symmetrical arc, described outer utmost point setting and the following outer polar-symmetric outer utmost point blade of.

The affixed quick union in the rear end of described handle.

This utility model is compared with present micro-wave scalpel, and the intensity with microwave launching site has improved 70%, improved cutting speed and solidify, closed blood vessel speed 70%, shorten operating time, reduce operating difficulty greatly, reduce functions such as intraoperative hemorrhage.Convenience freely during operation.And can reduce vascular inflow occlusion, and reduced the liver function infringement, help the recovery of postoperative liver function.Simultaneously, being both of surgical cut the effect of solidifying and killing the incisxal edge cancerous cell is arranged really, the incisxal edge that has reduced tumor shifts, and has improved surgical result.

Elaborate with accompanying drawing in conjunction with the embodiments:
