Title:
ULTRASONIC SCALPEL, ENERGY INSTRUMENT FOR SURGERY, AND POWER ADJUSTMENT METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/066077
Kind Code:
A1
Abstract:
An ultrasonic scalpel, an energy instrument for surgery, and a power adjustment method therefor. The ultrasonic scalpel comprises a hand-held part, a control module (16), an ultrasonic generator (122), and an ultrasonic cutter head, and further comprises the following modules: a load detection module, which is configured to detect the load conditions of the ultrasonic cutter head, the load detection module being electrically connected to an input end of the control module (16); a power conversion module, an input side thereof being electrically connected to an output end of the control module (16), and an output side thereof being electrically connected to the ultrasonic generator (122); the control module (16) is configured to receive a detection signal from the load detection module, and when an activation button is pressed, the control module (16) controls the power conversion module to adjust the output power of the ultrasonic generator (122). The ultrasonic scalpel, according to its own load conditions, automatically adjusts the output power of the ultrasonic generator (122); without affecting the operation effect, unnecessary amplitude of the cutter head is reduced in a no-load state, the service life of the scalpel is extended, and the single use cost of the ultrasonic scalpel is reduced.
