Title:
ULTRASONIC SCALPEL
Document Type and Number:
WIPO Patent Application WO/2024/077838
Kind Code:
A1
Abstract:
An ultrasonic scalpel, which comprises: a handle (1) and a blade (2); a first transition step (11) and a second transition step (12) are respectively connected to a proximal end and a distal end of a handle body (10), and each have a gradually decreasing cross-sectional diameter in a direction from the proximal end to the distal end; the distance between the second transition step (12) and a distal-end node (101) is in the range of λ/8±5mm, the distal-end node (101) being the position of the handle (1) having the smallest longitudinal amplitude. The ultrasonic scalpel blade further comprises a first cutting part (21) and a second cutting part (22) which are arranged on two opposite sides of a blade body (20) and which have lengths of λ/8 to λ/4. The first transition step (11), the second transition step (12), and the handle body (10) create a slimmer handle while simultaneously ensuring that the handle maintains longitudinal vibration, so as to alleviate the problem of the ultrasonic scalpel having unstable vibration modes. And providing the first cutting part (21) and the second cutting part (22) gives the blade of the ultrasonic scalpel a cutting function while simultaneously stabilizing the vibration state of the handle.
