The frequency and size of the vibration wave of device.
Control device and ultrasonic generator set and are integrated, control device can also be separately provided outside with ultrasonic wave
Generating means connects.High-frequency ultrasonic vibration enables cutter head is effortless to bore mill bone, and effective burr is organized to rigidity,
Soft tissue is reduced and damaged.This is due to that rigidity is organized due to its rigidity characteris, can largely absorb the vibrational energy of ultrasonic wave,
During with cutter head, rigidity tissue will not deform, and contact point is by vibration-extrusion rapid stock-removal.When insert contacts are to soft tissue, due to
Soft tissue has good compliance, with that can occur upper movement when insert contacts, deformation and resonance, so as to transmit eliminate it is super
The vibrational energy of sound wave, remaining energy are not enough to that soft tissue is caused to damage, therefore can at utmost reduce the wound to soft tissue
Evil.Mill femur is bored using ultrasonic activation and expands marrow, it is not necessary to which the Myelocavity file impacted with bone hammer, it is excessively right in the process of beaing to prevent
Injury caused by femur.
Further, the file head surface distribution edge of a knife, a kind of is that distributed intensive circular knife edge, circular knife edge periphery
There is small sawtooth；Another kind is that horizontal serrated edge is distributed with.By ultrasonic activation, marrow is expanded to femur burr.
Further, the supersonic generator is piezoelectric-type ultrasonic wave producer, the piezoelectric-type ultrasonic wave producer
The piezoelectric element of bag control longitudinal ultrasonic ripple vibration.
Further, the supersonic generator includes handle, there is control button on handle, the control button with it is described
Control device connects.Ultrasonic generator is arranged to T-shaped shape or handgun shape, with handle, holds more convenient, handle
There is control button above, can be may be provided in ultrasonic generator with control button, control device when hand handle is held, also may be used
It is external.
Compared with prior art, ultrasonic femoral myelocavity file grinding rigidity tissue, high-frequency vibrations can be reduced to femur
Tapping influences, and reduces tissue damage and amount of bleeding, reduces fracture to greatest extent and causes secondary damage.The utility model makes operation
Damage reduce, improve the operability, accuracy and security of operation.
