Ultrasonic orthopedic exquisite operation system

Abstract

The invention discloses an ultrasonic orthopedic exquisite operation system, including ultrasonic cutter used to transmit supersonic vibration. The ultrasonic cutter comprises an outer cutter body, an inner cutter body, and a support. The inner cutter body is connected with the outer cutter body through the support. The far end of the inner cutter body is provided with an end. The inner cutter body of a sacculus is in a cylindrical shape whose diameter uniformly gradually increases from the far end of the inner cutter body to the near end of the inner cutter body. In each 10 mm length, uniform gradual increment of the diameter of the inner cutter body is 0.1 mm to 0.15 mm. The outer cutter body is in a cylindrical shape whose diameter uniformly gradually increases from the far end of the outer cutter body to the near end of the outer cutter body. The system also comprises an upper support and a lower support. One end of the upper support is connected with an upper handle. One end of the lower support is connected with an electric telescopic rod. In a whole operation process, the system can adjust size of a cutter as needed, and monitor pressure applied on the cutter in real time, so as to reduce operation difficulty, and the system can preferably prevent injuries of soft tissues of a patient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an ultrasonic orthopedic fine surgery system. Background technique [0002] With the rapid development of modern medicine, ultrasonic surgery system has been widely used in clinical surgical treatment. It uses ultrasonic energy to perform surgical operations. Its outstanding features are fine cutting, safety, tissue selectivity and low temperature hemostasis. The use of ultrasonic orthopedic precision surgery system has greatly enriched the means of surgery, improved the quality of surgery, and reduced the pain of patients to a certain extent. Conventional ultrasonic bone surgery system, the system is mainly composed of a host, an ultrasonic handle, an ultrasonic cutter and a foot switch. The host mainly includes an ultrasonic signal generator, a power amplifier and an embedded computer. The low-power ultrasonic electrical signal generated by the ultrasonic signal generator c...

Problems solved by technology

[0008] In addition, in the existing ultrasonic bone surgery system, the ultrasonic knife may cut the bone and soft tissue at the same time when cutting the bone, which will not only affect the operation process, but also cause great harm to the patient

In the existing ultrasonic bone surgery system, there is no function to prevent the ultrasonic cutter from harming the bone and soft tissue

[0009] At the same time, the size of the knives is fixed and cannot be adjusted, and the pressure during the operation cannot be monitored. This undoubtedly tests the doctor's work experience and makes the operation more difficult.
