The operating principle of the present invention will now be described as follows: during the operation, the pre-sterilized and cleaned electrocoagulation hook is placed in a specified position. The coagulation hook is held. According to the surgical requirements, the doctor can adjust the working length of the coagulation hook by pulling or compressing the catheter 4. The specific adjustment process: pull the catheter 4 to make the catheter 4 and the handle 1 slide. When the catheter 4 passes through the limit groove 41 and the limit block 321 of the positioning sleeve 32, the catheter 4 performs damping sliding, thereby changing the working length of the electrocoagulation hook, so that the electrocoagulation hook can meet the operation requirements in different surgical environments. During the use of the electrocoagulation hook, the power supply of the electric hook head 7 is connected, so that the hook head 711 of the metal hook 71 conducts electrocoagulation and hemostasis at the lesion through the conductive ceramic coating 712, and the doctor separates and cuts the tissue through the inner side of the hook head 711. During the operation, a certain amount of blood isotonic fluid will be generated at the location of the lesion. At this time, the exudate will enter the cavity 42 through the water absorption hole 721 of the connecting tube 72, and will perform a certain absorption work through the water-absorbing silica gel 6. The water-absorbing silica gel 6 is constantly absorbing the exudate. During the process, the volume will expand and gradually fill the cavity 42 of the catheter 4, so as to avoid the influence of the seepage on the doctor's observation field, reduce the operation difficulty of the doctor during the operation, and improve the operation effect. During the operation, when the doctor needs to perform multi-angle separation and resection of the lesion tissue, the working direction of the hook head 711 of the electrocoagulation hook can be adjusted by the adjustment wheel 2, so as to avoid the operation of frequently changing and rotating the electrocoagulation hook, which increases the hidden danger of surgery. Adjustment method: friction and rotation of the adjustment wheel 2 makes the adjustment wheel 2 and the opening 11 of the handle 1 rotate, the adjustment wheel 2 drives the meshed gear ring 31 to rotate through the tooth slot 22, and the gear ring 31 drives the positioning sleeve 32 to rotate, positioning The sleeve 32 drives the catheter 4 to rotate through the limiting block 321 , and the catheter 4 drives the metal hook 71 to rotate and adjust, which is convenient for the doctor to perform multi-angle separation and resection of the tissue. After the operation, the medical staff removes the metal hook 71 from the catheter 4 by rotating the connecting tube 72, and connects the power supply of the heating device 5 through the cable 52, so that the heating block 51 of the heating device 5 can absorb water through the thermal conductive layer 43. The silica gel 6 is heated and evaporated. After the water-absorbing silica gel 6 is heated, water is precipitated from the silica gel, and then the volume of the water-absorbing silica gel 6 is changed, so that the water-absorbing silica gel 6 can be detached from the cavity 42 smoothly, which is convenient for medical staff to enter the catheter 4 and the metal hook 71 for disinfection and cleaning, and medical staff selectively fill in new water-absorbing silica gel 6 according to the use requirements of the coagulation hook, which is convenient for subsequent surgical work and improves the safety and hygiene factor during the use of the coagulation hook.
