Ultrasonic scalpel handle with suction apparatus and for laparoscopic rectal surgery

Abstract

The invention discloses an ultrasonic scalpel handle with a suction apparatus adjustable in flow rate and for a laparoscopic surgery, and relates to the field of surgical instruments, apparatuses or methods. The ultrasonic scalpel handle mainly comprises a multifunctional suction gun head tube, an ultrasonic scalpel gun head knob, a suction tube, an ultrasonic scalpel handle body, an ultrasonic scalpel head telescopic switch, a vent valve, a piston-type ultrasonic scalpel clamp-closing trigger, an ultrasonic scalpel firing trigger and a flow meter; the multifunctional suction gun head tube isintegrally connected with the ultrasonic scalpel handle body, and the suction tube is arranged inside and connected with the vent valve. The tail end of the suction tube is connected with a suction system. The ultrasonic scalpel handle has the advantages that through the combined functions of the piston-type ultrasonic scalpel clamp-closing trigger and the vent valve, the ultrasonic scalpel firingtrigger is triggered simultaneously, the suction system is started while an ultrasonic scalpel starts to work, accidents caused when the visual field gets lost due to the surgical smoke are avoided,and the ultrasonic scalpel draws back to the suction gun head tube to efficiently suck liquid in the abdominal cavity. The ultrasonic scalpel handle is simple in structure, convenient to process and use and suitable for clinical application and popularization.

Description

technical field [0001] The invention relates to the field of surgical instruments, devices or methods, in particular to an ultrasonic knife handle with a suction device with adjustable flow for laparoscopic surgery. Background technique [0002] We learned from a large number of clinical operations that laparoscopic surgery is generally accepted by patients due to its minimally invasive features, especially when dealing with the lower rectum, because the ultrasonic scalpel and instruments can pass through the narrow pelvic cavity, it has advantages over traditional open abdominal surgery huge. Of course, when the retrorectal space is treated with laparoscopic instruments, due to the narrow space, the surgical smoke generated by ordinary ultrasonic knife cutting tissue will inevitably contaminate the laparoscopic lens and cause complete or partial loss of the surgical field of view. The traditional method is: when the laparoscope is contaminated by surgical smoke, the laparo...
