In the embodiment of the invention, the elastic ring 19 has the characteristic of stress deformation, the elastic ring 19 can enter the outer sleeve 1 after shrinkage deformation, and when the elastic ring 19 is outside the outer sleeve 1, the shape similar to the fan shape is obtained. The cleaning net film 18 is fully covered with the elastic ring 19, and when the elastic ring 19 contracts and deforms, the cleaning net film 18 can follow the shape change of the elastic ring 19. When the blood clot is required to be cracked and cleaned, the elastic ring 19 is required to be positioned outside the outer sleeve 1, and when the elastic ring 19 is driven to rotate, the blood clot can be cracked by utilizing the contact between the rotating elastic ring 19 and the blood clot, and the cracked blood clot can be cleaned by utilizing the cleaning net film 18 so as to expose the position area covered by the blood clot before.
In fig. 8 to 10, it is also shown that the hemostatic head 7 and the electrocoagulation connector adopt a bipolar electrocoagulation fit mode, specifically, the electrocoagulation connector is a bipolar electrocoagulation connector 15, and a bipolar electrocoagulation power supply connection line 16 is arranged on the bipolar electrocoagulation connector 15; the broken cleaning link is a bipolar broken cleaning link 17, and the link rotation driving mechanism is a bipolar link rotation driving mechanism 20.
In specific implementation, the bipolar conducting body 22 is arranged in the bipolar fragmentation cleaning connecting rod 17, the bipolar electric coagulation connecting head 15 is electrically connected with the hemostatic head 7 through the bipolar conducting body 22, and the bipolar electric coagulation connecting head 15 is connected with an external bipolar electric coagulation power supply through the bipolar electric coagulation power supply connecting wire 16. The hemostatic head 7 is located at the end of the elastic ring 19, the hemostatic head 7 can be electrically connected with the bipolar lead 22 and the bipolar electrocoagulation connector 15 through the elastic ring 19, and the bipolar electrocoagulation hemostatic process performed by matching the bipolar electrocoagulation connector 15 with the hemostatic head 7 can be described with reference to the hemostatic process of the monopolar electrocoagulation, which is not described herein.
The bipolar connecting rod rotation driving mechanism 20, the bipolar coagulation connector 15 and the bipolar fragmentation sweeping connecting rod 17 are detachably connected, when the bipolar connecting rod rotation driving mechanism 20 is connected and matched with the bipolar fragmentation sweeping connecting rod 17, the bipolar connecting rod rotation driving mechanism 20 and the bipolar fragmentation sweeping connecting rod 17 can be mutually locked through the bipolar connecting rod rotation driving locking pin 21, and after the bipolar connecting rod rotation driving locking pin 21 is loosened, the bipolar connecting rod rotation driving mechanism 20 and the bipolar fragmentation sweeping connecting rod 17 can be conveniently separated.
The bipolar connecting rod rotation driving mechanism 20 can adopt a conventional driving mode, such as motor driving, and the like, and can be specifically selected according to requirements. Generally, when hemostasis is needed, the elastic ring 19 needs to be accommodated into the outer sleeve 1, and only the hemostasis head 7 is left outside the outer sleeve 1, so that a good hemostasis operation visual field is obtained.
Of course, in the specific implementation, when the hemostatic head 7 is matched with the bipolar electrocoagulation connector 15, the hemostatic head 7 and the bipolar electrocoagulation connector can also adopt the brush hemostatic head 6, namely, the connection and matching mode of the hemostatic head 7 and the electrocoagulation connector can not influence the specific implementation structure of the hemostatic head, and the hemostatic head can be specifically selected according to the needs, so long as the effects of chipping, cleaning and hemostasis on the blood clot can be realized.
