Abstract

The invention provides a dial device and a rotary knife for adjusting the rotation of a knife bar. The device comprises a dial body with a first through hole, a dial base and a locking structure. Theknife bar is pierced in the first through hole, and the knife bar and the dial body can synchronously rotate around the axial direction of the knife bar. The dial plate body is arranged on the dial plate base, and the dial plate base does not rotate with the dial plate body; the locking structure is arranged on the dial body and / or the dial base. The locking structure is used for locking the rotational position of the dial body when the dial body rotates to any preset position. Through the invention, the worker can directly and conveniently adjust the rotation of the knife rod.

Description

technical field [0001] The invention relates to the medical field, in particular to a dial device and a rotary cutter for adjusting the rotation of a knife rod. Background technique [0002] The rotary cutter can be understood as a tool for breast tumor biopsy and rotary cutting surgery. The cutter bar of the rotary cutter has a slot, which can also be understood as opening, cutting, etc. During the operation, the knife bar The rotation needs to be controlled so that the position of the slot can be rotated to match the position of the tumor, so that it is suitable for the implementation of the operation. [0003] In the existing related technologies, electronic equipment is usually used to drive the rotation of the knife rod, such as the rotary cutter designed by Bard Company, which uses the main control terminal to control the operation of the motor, and then uses the motor to drive the rotation of the knife rod. [0004] However, this method is not convenient for releva...
