Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

At present, from the development of market situation, the medical ultrasonic scalpel is also gradually applied to surgical operation, and due to the characteristics of ultrasound, when the medical ultrasonic scalpel is in contact with bone tissue with higher hardness, the bone tissue is not easy to deform, so that cutting or crushing can be generated at the contact position, and when the medical ultrasonic scalpel is in contact with soft tissue, the soft tissue can be bounced or deformed under the elastic action of the soft tissue, and micro-vibration is performed along with the vibration of the medical ultrasonic scalpel, so that the energy at the position of a scalpel head is offset, and the cutting or crushing is avoided. Therefore, the bone cutting advantages of the medical ultrasonic scalpel are obvious especially for the surgical operation of which the operation position is near the interface of the bone and the soft tissue.

The applicant has noticed that, in the related art, when the medical ultrasonic scalpel is used for cutting or crushing the bone tissue, the bone tissue is drilled mainly through the cutter head of the medical ultrasonic scalpel, and the bone tissue to be cut or crushed is ground or cut into bone blocks with small volume to realize the treatment of the bone tissue. However, the hardness of the bone tissue is high, the cutting or crushing speed of the bone tissue is slow, and the working efficiency is low.

In order to improve the work efficiency of medical supersound sword, this application embodiment provides a medical supersound sword, and medical supersound sword includes the tool bit, and the tool bit has first terminal surface and cutting groove, and cutting groove passes first terminal surface, and cutting groove makes first terminal surface form at least one annular cutting plane. When cutting or broken bone tissue, the bone tissue that the position of cutting groove place corresponds can not contact with the cutting plane, also need not be cut or broken, thereby the bone tissue that the periphery of cutting groove (also annular cutting plane) corresponds can be cut or broken with the cutting plane contact, the cutting plane of cutting face to bone tissue is less like this, but still can cut or break out great bone piece, simultaneously because the cutting face is little to the cutting or broken face of bone tissue, cut or broken equally big bone piece, the medical ultrasonic knife that this application embodiment provided is used the time shorter, and is fast, and work efficiency is higher.
