Abstract

An embodiment of the invention discloses an ultrasonic scalpel for hepatectomy and a use method of the ultrasonic scalpel, and particularly relates to the field of ultrasonic scalpels. The ultrasonicscalpel comprises a main machine, wherein a chassis is fixedly mounted at the bottom end of the main machine, a foot switch is arranged on one side of the main machine, the main machine is connected with the foot switch through a wire, a handle is arranged on one side of the main machine, a transducer is fixedly mounted at the top end of the handle, and a connecting pipe is arranged on one side ofthe transducer. By arrangement of a base, a mounting plate, a positioning block and second limiting rods, when a scalpel head is mounted, the base at one end of the scalpel head needs to be embeddedinto the mounting plate, and a positioning groove in the bottom end of the base is matched with the positioning block, then, the second limiting rods in inner grooves are attracted by second magneticblocks on an outer ring and move towards one side of the second magnetic blocks, the second limiting rods are inserted into clamping grooves in the two sides of the mounting plate to fix the base, andthe scalpel head thus can be mounted and dismantled by people conveniently.

Description

technical field [0001] Embodiments of the present invention relate to the field of ultrasonic scalpel, in particular to an ultrasonic scalpel for liver resection and a method for using the same. Background technique [0002] At present, the existing ultrasonic scalpel system consists of a host, a foot switch, an ultrasonic transducer, a connecting cable and an ultrasonic scalpel. Among them, the host is used to generate high-frequency current, the foot switch excites the output of ultrasonic energy, the transducer and the connecting cable convert the current into ultrasonic vibration, and the vibration transmits the ultrasonic energy to the tip of the knife through the blade of the ultrasonic scalpel. Contact friction produces mechanical cutting and blood coagulation. [0003] The prior art has the following deficiencies: the existing cutter head and the through groove of the main body are fixed by threads or bolts. The use is prone to wear and tear. Contents of the inve...
