Ultrasonic scalpel head with soft tissue rapid coagulation cutting function

Abstract

The invention discloses an ultrasonic scalpel head with a soft tissue rapid coagulation cutting function, which comprises a forceps head and a scalpel rod part, and is characterized in that the forceps head comprises a movable forceps head part positioned at the upper end and a fixed forceps head part positioned at the lower end, the movable forceps head part comprises a movable metal forceps head, and the fixed forceps head part comprises a fixed metal forceps head. The tail part of the movable metal plier head is connected to the tail end of the fixed plier head part through a rotating shaft; a first semiconductor insulation heating electrode is arranged on the inner side of the movable metal clamp head, and a conductive Teflon pad is arranged in the first semiconductor insulation heating electrode. The fixed tong head part comprises a second semiconductor insulation heating electrode, and the first semiconductor insulation heating electrode and the second semiconductor insulation heating electrode correspond to each other up and down in position; the cutter bar part comprises an ultrasonic cutter bar and an outer tube, the other end of the ultrasonic cutter bar is connected with the controller, and the outer tube wraps the ultrasonic cutter bar. The coagulation depth and effect are guaranteed, the coagulation speed is increased, and the operation time is shortened.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic knife, and in particular relates to an ultrasonic knife head with the function of rapid coagulation and cutting of soft tissue. Background technique [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 long, so it cannot match the cutt...

[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
