Title:
ULTRASONIC SCALPEL
Document Type and Number:
WIPO Patent Application WO/2023/061384
Kind Code:
A1
Abstract:
An ultrasonic scalpel, comprising a drive handle (8), a scalpel head assembly (1), and a hollow electric motor (4), wherein the scalpel head assembly (1) comprises a scalpel bar (101) and a scalpel head (102), which is arranged at one end of the scalpel bar (101), a cavity being provided at the other end of the scalpel bar (101), external threads being provided at the end of the drive handle (8) close to the scalpel bar (101), and the cavity being internally provided with internal threads adapted to the external threads; and the hollow electric motor (4) is internally provided with a channel allowing the scalpel bar (101) to pass through, and under the condition where the scalpel bar (101) can pass through the hollow electric motor (4), the hollow motor (4) can drive the scalpel bar (101) to rotate. Thus, the end of the scalpel bar (101) having the cavity passes through the hollow electric motor (4), such that the external threads of the drive handle (8) make contact with the internal threads in the cavity, and then, the hollow electric motor (4) is started to drive the scalpel bar (101) to rotate. The scalpel bar (101) is in threaded connection with the drive handle (8), such that it is unnecessary for an operator to manually rotate the scalpel bar (101), saving on time and energy.
