Torque performance testing device for real-time visualization of torque of surgical instrument

Abstract

The invention relates to a torque performance testing device for real-time visualization of the torque of a surgical instrument. The device comprises a universal quick-change handle, a handle connector, a mechanical performance tester, a signal processor, a front adapter, a locking device, a protection sleeve and a signal display screen, wherein the universal quick-change handle, the handle connector, the mechanical property tester, the front adapter and the protective sleeve are connected in sequence, one end of the protective sleeve sleeves the front adapter, the signal processor is arranged on the mechanical property tester, the mechanical property tester, the signal processor and the signal display screen are electrically connected in sequence, the front adapter is hollow, the locking device is arranged on an inner wall of the protective sleeve and penetrates through the front adapter inwards, and the surgical instrument is inserted into the front adapter through the protective sleeve and fixed by the locking device. Compared with the prior art, real-time visualization of the torque performance of the surgical instrument in the clinical use process is achieved, a doctor can conveniently and accurately operate, control and implement an operation, and secondary injury of the operation is reduced and avoided.

Description

technical field [0001] The invention belongs to a torque performance testing device, in particular to a torque performance testing device for real-time visualization of surgical instrument torque. Background technique [0002] Orthopedic surgical instruments are widely used in clinical operations, and there are certain risks in the implementation and operation of the instruments. Doctors rely on their experience and proficiency to judge and adjust the force generated by the instrument during use, but they cannot quantify the magnitude of the force. Therefore, it is easy to cause secondary injury to the patient during the use of surgical instruments, especially when the instrument needs to be used. When the joints are rotated to achieve joint expansion, etc. In this case, even experienced doctors can easily cause damage to cortical bone and other tissues, and may even cause damage to the rest of the patient's bone except the diseased bone, which increases the chance of posto...
