Gliding and swinging type orthopaedics positioning guide needle guider

Abstract

The invention discloses a gliding and swinging type orthopaedics positioning guide needle guider. The gliding and swinging type orthopaedics positioning guide needle guider comprises a fixing board, a sliding board, a first connection rod, a first rotation rod, a second rotation rod, a second connection rod, a height adjusting board, an aiming needle, a guide sleeve and multiple fastening members, wherein the sliding board is mounted on the fixing board, the first connection rod is fixedly connected with the sliding board, the first connection rod, the first rotation rod, the second rotation rod and the second connection rod are in movable connection sequentially through the fastening members, the second connection rod is provided with a sliding groove, the height adjusting board is mounted in the sliding groove, and the aiming needle and the guide sleeve are respectively mounted at two ends of the height adjusting board vertically. Through the gliding and swinging type orthopaedics positioning guide needle guider in matching with the image technology, accuracy of positioning needles can be effectively improved during enforcement of a femur head neck operation, wound-less verification can be realized, and a problem of instability caused by manual operation can be solved.

Description

technical field [0001] The invention belongs to orthopedic medical equipment, which is an auxiliary positioning equipment. Background technique [0002] At present, in proximal femoral surgery, such as femoral neck fracture internal fixation and femoral head necrosis modified decompression and fibula transplantation, the positioning guide pin is placed by the doctor's bare hands under the guidance of a C-arm X-ray machine, which is accurate. The safety, safety and effectiveness are low, and it is difficult to obtain the ideal biomechanical configuration in the narrow geometric space of the femoral neck; repeated needle puncture will further damage the remaining normal bone structure of the femoral head and neck, resulting in unnecessary medical treatment. In addition, repeated fluoroscopy requires patients and doctors to receive a considerable dose of ionizing radiation, which is also quite harmful. Contents of the invention [0003] The purpose of the present invention i...
