Embodiment 1
[0036]As shown in the figure: a multifunctional head, including an annular body 8-1, the front face of the annular body 8-1 has 6 grooves evenly distributed along its circumferential direction, and 3 sound sources are arranged at intervals in the 6 grooves Part 8-2 and the first suction head 8-3, the sound frequency of the sound source part 8-2 is 2-3kHz, and the suction head 8-3 is connected with the negative pressure suction source through a pipeline.
[0037] The multifunctional head 8 is an auxiliary accessory for increasing the function of the hemostat, and has the functions of sound wave emission and smoke suction. While the electrocoagulation operation is in progress, the sound source on the multifunctional head emits sound waves with a frequency of 2-3kHz. Through the agglomeration mechanism of the sound waves, the smoke generated during the electrocoagulation operation is reunited at the beginning of appearance, reducing the The formation scale of the smoke avoids the...
Embodiment 2
[0039] As shown in the figure: an electrocoagulation hemostat for hepatobiliary surgery, including an insulating outer sleeve 5, a conductive rod 6, a scraping electrocoagulation head and the multifunctional head in Example 1, through which the scraping electrocoagulation head is screwed The upper part is arranged on the head end of the insulating outer casing 5, and the conductive rod 6 is penetrated in the insulating outer casing 5. The head end of the conductive rod 6 is connected with the electrocoagulation rod 1 of the electrocoagulation head, and the tail end of the conductive rod 6 is connected with the power supply. Connected, the conductive rod 6 can move along the axis in the insulating outer sleeve 5, and then drive the electrocoagulation rod 1 to extend or retract inside the reducing head 2, and the multifunctional head 8 is sleeved on the head end of the insulating outer sleeve 5.
[0040] Scab scraping electrocoagulation head, including electrocoagulation rod 1 an...
