Posterior vascular nerve protector of tibia

Abstract

The invention discloses a posterior vascular nerve protector of a tibia, and belongs to the technical field of orthopedic medical instruments. The protector is applied to the fracture of a tibial plateau and used for protecting posterior vascular nerves of the tibia. The protector is characterized in that a protecting plate is a rectangular plate, the rear end of the protective plate is connectedwith the lower end of a sleeve tube through a rotary shaft, a thread is arranged in an inner hole of the sleeve tube, a thread matching with the inner hole thread of the sleeve tube is arranged on a screw rod, the lower portion of the screw rod is screwed in the sleeve tube, the rear portion of the protective plate is provided with a connecting plate shaft which is connected with the lower end ofa connecting plate, the connecting plate is parallel to the sleeve tube, the upper end of the connecting plate is perpendicularly connected with the front end of a handle, the handle is horizontally placed, a circular hole is formed in the front portion of the handle, and the screw rod perpendicularly penetrates through the circular hole of the handle and is connected with the handle. By means ofthe protector, the difficult problem of how to prevent from the posterior vascular nerves of the tibia from damaging during a tibial plateau resetting operation is solved, the popliteal artery and nervi tibialis at the rear side of the tibia can be effectively protected to provide effective technical support for the smooth implementation of the tibial plateau resetting operation, and the protectorhas an extreme practical clinical meaning.

Description

Technical field [0001] The invention relates to a surgical instrument used for protecting tibial plateau fractures and vascular nerves on the posterior side of the tibia during surgery, and belongs to the technical field of orthopedic medical instruments. Background technique [0002] Tibial plateau fractures are common intra-articular fractures in clinical practice, and are more common in middle-aged and young people suffering from high-energy injuries. Due to the complex and changeable fracture shapes, clinical treatment is more difficult. The purpose of the treatment of tibial plateau fractures is to restore the articular surface and lower limb lines of force, firmly fix the fracture, and avoid postoperative traumatic arthritis, joint stiffness and other long-term complications. The key step in the surgical treatment of tibial plateau fractures is to reset the displaced fragments. In order to obtain a good surgical field of vision during the reduction process, it is often nec...

Problems solved by technology

Due to the concealed position of the nerves and blood vessels on the posterior side of the tibia, how to prevent injury during the operation has become a difficult problem for the surgeon. So far there is no good solution, and it needs to be solved urgently.
