Problems solved by technology

In the current application of ultrasonic scalpels, cutting and coagulation are a pair of contradictions, which need to be balanced: sharp blades cut fast but have poor coagulation effects, blunt blades pressurize blood coagulation well but cut speed is slow fever

Embodiment Construction

[0029] The present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0030] Such as figure 1 An ultrasonic scalpel is shown, which includes a fastening bolt 500, a rear end block 400, a piezoelectric ceramic body 300, a horn 100, and a cutter head 200 connected in sequence from far to near. An oblique groove 101 is arranged on the top, and a transverse split 201 is formed at the front section of the cutter head, which divides the cutter head into two blades 202,203. And at least one side edge of the front end of the cutter head is provided with a cutting edge 204 . In the technical solution of the present invention, the front section of the proximal end of the horn is provided with an oblique cut groove 101, and is fastened together with the piezoelectric ceramic body 300 by threads, so that the longitudinal vibration of the piezoelectric ceramic body 300 is transferred to the front end of the horn. Composite v...

Abstract

The invention discloses an ultrasonic scalpel capable of improving cutting and hemostatic effects simultaneously. The ultrasonic scalpel comprises a piezoelectric ceramic body, an amplitude-change pole and a scalpel head which are connected sequentially from far to near, inclined cutting grooves are formed in the front segment of the near end of the amplitude-change pole, a transverse splitting slot is formed in the front end of the scalpel head and divides the scalpel head into two pieces, and the scalpel head and the amplitude-change pole convert longitudinal vibration of a transducer into compound vibration formed by producing transverse vibration at the front end of the scalpel head. The ultrasonic scalpel capable of improving the cutting and hemostatic effects simultaneously has the advantages that blood is coagulated more effectively through ultrasonic vibration perpendicular to cutting surfaces, and the shape cutting edge can cut rapidly, so that the defect that a traditional ultrasonic longitudinal-vibration scalpel is bound to be used for either cutting or hemostasis is made up; the transverse vibration at the front end of the scalpel head with the splitting slot is amplified locally, so that efficiency of an integral ultrasonic vibration system is also improved.

Description

technical field [0001] The invention relates to a medical device and a method thereof, in particular to an ultrasonic scalpel. Background technique [0002] Ultrasonic scalpel has been used on a large scale for more than 20 years. Compared with other surgical methods, its advantages are: less smoke, clear surgical field of view, less thermal damage, and the functions of tissue cutting, coagulation and separation, and can Precisely control the range of cutting and coagulation, there is no possibility of electrical damage, fast oscillation has a self-cleaning effect, and there will be no adhesion between the knife and the tissue. [0003] At present, there are two basic styles of ultrasonic scalpels commonly used for cutting coagulation: one is a slice knife with a sharp, flat, blunt edge, and the other is a scissor knife with a clamping function. The sharp side is used for quick cutting, while the flat or blunt side is used for hemostasis; scissor knives are usually blunt, h...
