An ultrasonic cutter head with the function of rapid coagulation and cutting of soft tissue

Abstract

The invention discloses an ultrasonic cutter head with the function of rapid coagulation and cutting of soft tissue, which includes a clamp head and a cutter bar part, and is characterized in that the clamp head includes a movable clamp head part located at the upper end and a fixed clamp head part located at the lower end. The movable pincer part includes a movable metal pincer, and the tail of the movable metal pincer is connected to the tail end of the fixed pincer part through a rotating shaft; the inner side of the movable metal pincer is provided with a first semiconductor insulated heating pole, and the The inside of the first semiconductor insulating heating pole is provided with a conductive Teflon pad; the fixed clamp head part includes a second semiconductor insulating heating pole, and the positions of the first semiconductor insulating heating pole and the second semiconductor insulating heating pole correspond up and down; The cutter bar part includes an ultrasonic cutter bar and an outer tube, the other end of the ultrasonic tool bar is connected to the controller, and the outer tube wraps the ultrasonic tool bar. The invention ensures the depth and effect of coagulation, accelerates the coagulation speed and reduces operation time.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic knives, and in particular relates to an ultrasonic knife head with the function of fast coagulation and cutting of soft tissue. Background technique [0002] In traditional soft tissue ultrasonic surgery, due to the maximum power limit of high-frequency electrocautery (less than 300W), thicker tissues and blood vessels coagulate slowly. In order to reduce bleeding, bipolar electrocautery is usually used to first coagulate and then replace the soft tissue ultrasonic knife. The cutting method is cumbersome and has poor consistency, which will greatly prolong the operation time and increase the cost; some manufacturers integrate the monopolar or bipolar coagulation function on the ultrasonic cutter head, which can shorten the operation time, but the use of ordinary The coagulation time of bipolar coagulation is still long, so it cannot match the cutting speed of the ultrasonic knife. Only coagulat...

Problems solved by technology

[0002] In traditional soft tissue ultrasonic scalpel surgery, due to the maximum power limit of the high-frequency electric scalpel (less than 300W), the coagulation process of thicker tissues and blood vessels is slower. In order to reduce bleeding, bipolar electric scalpels are usually used to coagulate first and then replace the soft tissue ultrasonic scalpel Cutting method, this method is cumbersome and poor in consistency, which will greatly prolong the operation time and increase the cost; some manufacturers integrate the monopolar or bipolar coagulation function on the ultrasonic knife head, which can shorten the operation time, but using ordinary The coagulation time of bipolar electrocoagulation is still relatively long, so it cannot match the cutting speed of the ultrasonic knife, and electrocoagulation or ultrasound can only be started separately. Judging the coagulation depth based on experience often causes bleeding due to insufficient tissue coagulation, which affects the surgical effect and prolongs the operation time
