Further, cutter head and the cutter head sheath is fixedly connected by an at least spline connection structure.
Further, a switch module is further included.
Further, the switch module includes switch button, the conducting slip ring and one being arranged on the cutter head sheath
Connect a connection cables of the switch button and conducting slip ring.
Further, the switch module includes the switch button being arranged on the cutter head sheath and wireless signal is sent
Device, the radio signal senders receive the switching signal of switch button, and the switching signal is transferred to a host, the host
According to switching signal driving or stop ultrasound-driven handle.
Further, the anti-recycling component includes：
It is sheathed on a cover body of the cutter head sheath front portion, fixing groove before the inside of its front end has one；
One be formed on the cutter head sheath outer wall is raised, fixing groove after which has one；
The spring being sheathed on outside the cutter head sheath, the both ends of the spring are individually fixed in preceding fixing groove and rear fixing groove；
The rear end of the cover body has a hook-like assembly unit, and for the cutter head sheath outer wall formed with a spacing annular protrusion, this is hook-shaped
Component convexes to form a destructive limit assembly with the spacing annular；
The side wall of the cover body formed with an at least guide groove, the cutter head sheath outer wall formed with an at least guide groove pair
At least guide rod answered.
Further, the spring is a compression spring, and when the destructiveness limit assembly is in buckling state, which is in
Compressive state.
Further, when the destructiveness limit assembly, which is destroyed, releases spacing, under the elastic force effect of the spring, the cover
Body slides to cutter head front end and covers cutter head front end, until guide rod stops contacting with the rear end in contact of guide groove.
By taking above-mentioned technical proposal, cutter head sheath, cutter head are connected with manual switch component and be integral, is being used
When, it is connected by the screw thread of cutter head afterbody with ultrasound-driven handle, you can disposable in operation, connection mode facilitates fast
Victory, due to using disposable design, without disinfection is repeated, reduces in terms of hospital for disinfection means and sterile environment
It is required that and save man power and material.In addition, by being related to anti-retracting device, after a single use, by cover body by before cutter head
End shield is lived, and is made ultrasonic surgery cutter head be difficult to directly recycle, is avoided criminal's Reusability.
Brief description of the drawings
Fig. 1 is the structure diagram of the ultrasonic surgical blades with disposable cutter head in one embodiment of the invention.
