Tibial tuberosity traction nail embedding guider

Abstract

The invention discloses a tibial tuberosity traction nail embedding guider, comprising a tibial tuberosity base, a tibial distal base and a connecting rod, wherein the tibial tuberosity base and the tibial distal base are fixed on the tibial crest separately, and form a force line support by the connecting rod. The force line support is parallel to the tibial crest; the tibial distal base is a fixing device; the tibial tuberosity base comprises a visual level, a horizontal hole, a horizontal connecting rod and a hollow connecting rod; the visual level is installed on the top of the tibial tuberosity base and used for checking the precise position of a nail during nail embedding; the horizontal hole is a horizontal through hole of the tibial tuberosity base; the horizontal connecting rod can freely slide in the horizontal hole and keeps perpendicular to the force line support; and when fixation is needed, the horizontal connecting rod is fixed at the horizontal position of the tibial tuberosity base by a fixing bolt in the horizontal hole. Finally, an optimal and perfect nail path that the traction nail is perpendicular to the tibia in the longitudinal direction and parallel to the tibia in the horizontal direction can be obtained.

Description

technical field [0001] The invention belongs to the technical field of medical equipment. Background technique [0002] Severely displaced femoral shaft and proximal femoral fractures often require emergency tibial tuberosity traction for reduction and fixation. [0003] Because orthopedic surgeons can only rely on personal experience and are affected by operating conditions, the nails are often not accurately perpendicular to the tibia when placing the nails, which directly affects the traction effect. Sometimes even larger deviations occur, leading to traction failure or avulsion fracture of the tibial tuberosity. [0004] In the prior art, the Chinese utility model patent CN 204931819 U disclosed on 2016.01.06 is a tibial tubercle traction operation locator, which includes a fixed frame and a sliding side plate, and the sliding side plate is arranged in the fixed frame; the fixed frame consists of a square Composed of groove and side wall, the side wall is set at one en...
