Problems solved by technology

However, in the actual operation of this traction device, because the tunnel mouth cannot be viewed directly under the microscope, the lead wire catheter is difficult to insert into the tibial tunnel catheter, and the medical steel wire is inconvenient to pass through the tibial tunnel smoothly, so it cannot be used very reasonably and conveniently. Cannot be operated flexibly, there are great limitations in use

Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described below with reference to the accompanying drawings.

[0027] Such as Figure 1 to Figure 6 As shown, a tibial tunnel over-the-line traction push-pull device dedicated for orthopedic surgery includes an extending tube 2 adapted to pass through the tibial tunnel 1, and the extending tube 2 is a hollow tube-like structure. A notch 21 for hanging and locking the wire is provided on the pipe wall extending into the front end of the pipe body 2 , and the pulling wire 6 is hung or locked by using the notch 21 . A movable push-pull rod 3 is installed in the tube, and the movable push-pull rod 3 includes a straight rod body 31. The front end of the straight rod body 31 is connected with an elastic action block 32 for pulling or pushing the tibial tunnel through the line. The elastic action block 32 is an arc-shaped block structure, and the bending arc of the elastic action block 32 can be defo...

Abstract

The invention discloses a tibial tunnel pass thread dragging, pushing and pulling device special for orthopedic surgery. The device comprises a stretching-in pipe capable of penetrating through a tibial tunnel in adaptive mode. A movable push-pull rod is arranged in the pipe in a matched mode. The bending radian of the front working end of the movable push-pull rod can deform after force is borne and be automatically and elastically restored. When the device penetrates through the tunnel, the front end of the device can be sent to a position of which the height is 1-2 cm higher than the tunnel plane, a dragged thread is convenient to grasp or push out, the front end of the movable push-pull rod can be customized according to different thread pushing and dragging functions, and the bending radian of the movable push-pull rod can be customized to meet different strength requirements. Medical staff can more conveniently drag, push and eject the pass thread passing through the tibial tunnel, the push-pull rod can be rapidly replaced according to different surgical requirements, a doctor can conveniently perform surgical operation, pain of a patient is relieved, and the success rate of the surgery is increased.

Description

technical field [0001] The invention relates to the field of medical instruments and equipment, more specifically to a tibial tunnel thread-passing traction push-pull device dedicated to orthopedic surgery. Background technique [0002] The rupture of the posterior cruciate ligament of the knee joint or the fracture of the insertion point of the posterior cruciate ligament of the knee joint is a common type of knee joint injury. For these two kinds of knee joint injuries, the current domestic and foreign routine surgical methods are to perform arthroscopic posterior cruciate One of the operational difficulties in ligament reconstruction or posterior cruciate ligament fracture reduction and internal fixation lies in the step of sending the ligament traction line from the front of the tibial tunnel to the back of the tibial tunnel, and then back to the front of the knee joint. Because the standard anatomical position of the insertion point of the posterior cruciate ligament is...
