本发明在使用时，可以先通过内窥镜和微型摄像头确定病人患处范围，然后根据情况转动端面凸轮11调节弧形板7伸出的数量，实现对微波探头2辐射范围的调节，当需要对弧形板7进行复位即使得限位块8伸入到限位孔内，以及限位块8和弧形板7进入到套筒5内时，转动复位盘，使得复位块对着需要收回的弧形板7，然后通过摁压操纵杆19带动导向杆6向上运动，进而带动复位块16向上运动，复位块16的倾斜面推动限位块8缩回限位孔内，然后驱动压簧10带动弧形板7缩回套筒5内。When the present invention is in use, the scope of the patient's affected area can be determined first through the endoscope and the miniature camera, and then theend face cam 11 can be rotated according to the situation to adjust the amount of the arc-shapedplate 7 protruding, so as to realize the adjustment of the radiation range of themicrowave probe 2. When thearc plate 7 is reset, thestop block 8 is stretched into the limit hole, and when thestop block 8 and thearc plate 7 enter thesleeve 5, the reset disk is rotated so that the reset block faces the position that needs to be recovered. The arc-shapedplate 7 then drives theguide rod 6 to move upward by pressing thejoystick 19, and then drives thereset block 16 to move upward. Drive thecurved plate 7 to retract in thesleeve 5 .

本发明的有益效果是：通过伸出套管的弧形板的数量，来控制微波探头2的辐射范围，实现对病人病处进行精确的控制治疗，减少对患者非病处的创伤，较少患者痛处，有利于术后的快速回复；利用端面凸轮的转动能够很好的控制弧形板伸出套筒，操作简单，同时，控制弧形板复位的机构简单，操纵方便。The beneficial effects of the present invention are: the radiation range of themicrowave probe 2 is controlled by the number of arc-shaped plates protruding from the sleeve, so that precise control and treatment of the diseased part of the patient can be achieved, and trauma to the non-diseased part of the patient can be reduced, and less Patient's sore spot is conducive to rapid postoperative recovery; the rotation of the end face cam can well control the extension of the arc-shaped plate from the sleeve, and the operation is simple. At the same time, the mechanism for controlling the reset of the arc-shaped plate is simple and easy to operate.

以上所述的实施例并非对本发明的范围进行限定，在不脱离本发明设计构思的前提下，本领域所属技术人员对本发明的技术方案作出的各种变形和改进，均应纳入本发明的权利要求书确定的保护范围内。The above-described embodiments do not limit the scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by those skilled in the art to the technical solution of the present invention shall be included in the rights of the present invention. within the scope of protection specified in the requirements.
