Title:
TORQUE WRENCH FOR ULTRASONIC SCALPEL AND CAPABLE OF PREVENTING OVERTIGHTENING
Document Type and Number:
WIPO Patent Application WO/2024/051142
Kind Code:
A1
Abstract:
The present utility model relates to the technical field of ultrasonic-scalpel assembly and disassembly wrenches, and in particular to a torque wrench for an ultrasonic scalpel and capable of preventing overtightening. The torque wrench comprises a wrench main body, wherein a recess body is formed in the center of an edge on one side of the wrench main body, and a wrench seat is provided on an inner wall of the recess body. The advantages of the present utility model lie in that a rotating head of an ultrasonic scalpel is sleeved by means of a wrench hole, so that the scalpel can be fixed; the wrench main body is rotated, and then one sliding engagement block can abut against a fixed engagement block and the wrench seat is driven to rotate, so that the scalpel can be driven to rotate so as to realize tightening; after tightening is performed in place, a tightening force continues to be applied and then the sliding engagement block is guided by means of a bevel to come back to an inner wall of a corresponding guide slot, so that the wrench main body is rotated, and the tightening of the wrench seat is stopped to prevent a connecting portion of the scalpel from being damaged due to overtightening; and when the ultrasonic scalpel is disassembled, the wrench main body only needs to be rotated reversely to enable the sliding engagement block and the fixed snap-fit block to abut against each other, so that the wrench seat can be driven to rotate reversely, thereby realizing the disassembly of the scalpel.
