Wherein, when handle 1, working head 2 and pole body subassembly 3 can be dismantled and connect, modes such as solid, screw-thread fit, grafting of accessible card realize dismantling the connection, for example: the working head 2 is connected with the handle 1 in a clamping mode, and the working head 2 is connected with the rod body device 3 in a plugging mode.
The working head 2 includes a housing 21, and a rotary head 22 mounted on the housing 21. The rotation of the rotator head 22 may rotate the shaft member 3. Optionally, the housing 21 is provided with an opening for connecting the swivel head 22 with the shaft assembly 3, the opening being located within the swivel head 22.
The rotary head 22 is provided with a first rotary part which rotates relative to the working head 2, correspondingly, the part of the working head 2 butted with the rotary head 22 is provided with a second rotary part, and the first rotary part and the second rotary part are mutually matched to realize that the rotary head 22 rotates relative to the working head 2. In one example, the first rotating portion is a protrusion, and the second rotating portion is a groove matched with the protrusion.
Of course, the rotator head 22 may also include other components, such as: a connector connected to the shaft member 3, and the like.
In this application, in order to avoid the problem that the medical staff manually twists the rotating head 22, which results in lower operating efficiency of the medical instrument, the working head 2 further includes a rotating head driving assembly 23 for driving the rotating head 22 to rotate around the central axis. The medical device further comprises: a control circuit 4 for controlling the movement of the rotary head driving assembly, and a rotary start-stop switch 5 for controlling the connection or disconnection of the control circuit 4 and the rotary head driving assembly 12.
In one example, when the rotation start-stop switch 5 receives a pressing operation, the control circuit 4 communicates with the rotary head driving assembly 23, so that the rotary head driving assembly 23 drives the rotary head 22 to rotate; when the rotation start/stop switch 5 does not receive the pressing operation, the control circuit 4 is disconnected from the spin head driving assembly 23, so that the spin head driving assembly 23 stops driving the spin head 22 to rotate.
