Positioning Mechanism And Manufacturing Method Of Surgical Robot

1. The present utility model relates to the technical field of medical instruments, in particular to a positioning mechanism and a surgical robot.

Background technique:

2. With the development of minimally invasive medical technology, cryoablation has been widely used in the treatment of tumor diseases in the liver, kidney, prostate, soft tissue and other parts. Cryoablation is a surgical technique that uses cryoablation to eliminate target tissue. Compared with previous radiofrequency ablation, patients do not have to tolerate high temperature during cryoablation, which can reduce pain. The principle of cryoablation is to deliver liquid refrigerant to the target ablation site through a cryoablation needle, and the liquid refrigerant absorbs heat and evaporates to take away the tissue heat, lowering the temperature of the target ablation site and destroying abnormal cells and tissues.

3. Specifically, the process of cryoablation is generally as follows: the doctor first uses a biopsy gun to manually puncture the sample, and then uses an ablation needle to perform manual cryoablation after the sampling is completed. When performing puncture sampling and ablation treatment on the same lesion, it is necessary to rely on the doctor's experience to locate them separately, and the surgical accuracy cannot be guaranteed.
