A positioning aid device for femoral neck fracture and its application method

Abstract

The invention discloses a positioning aid for femoral neck fracture, which comprises a base, a frame, an aiming block, a fixing column A and a fixing column B, wherein the frame is vertically set up on the base and can be placed on the The base plane rotates around the longitudinal axis of the frame; the fixed column A is fixed on the top of the frame; the aiming block is mounted on the frame through a rotating shaft, and the aiming block can be arranged It can move freely in the chute on the side and can be fixed at any position. At the same time, the aiming box can rotate around the rotating shaft. Several positioning holes are opened on the surface of the aiming box. The fixing column B is detachably fixed on the The center of the surface on which the positioning hole is set. The invention can reduce operation time, reduce operation trauma, reduce blood loss, reduce damage to femoral neck bone, reduce X-ray perspective times, and reduce radiation to patients and medical staff.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a positioning auxiliary device for femoral neck fractures. Background technique [0002] Femoral neck fractures are frequent fractures in adults. In recent years, with the increase of average human life expectancy, the incidence of femoral neck fractures has shown an obvious upward trend. This type of fracture has a high disability rate and mortality rate. Once a patient fractures, if no operation Treatment requires long-term bed rest, which greatly increases the chance of related complications, such as hypostatic pneumonia, bedsores, deep vein thrombosis, muscle atrophy, osteoporosis, urinary system infection, osteoporosis, and increases the chance of femoral head necrosis . [0003] The purpose of internal fixation for femoral neck fractures is to anatomically reduce the fracture as much as possible, reduce the incidence of femoral head necrosis, obtain firm fixation of the ...

AI Technical Summary

Problems solved by technology

[0005] In the current medical situation, when the doctor inserts the guide pin into the predetermined position of the femoral neck, he usually inserts the guide pin based on experience, and often cannot place the guide pin into the predetermined position at one time, and needs to be inserted and pulled out repeatedly. Repeat the operation until the position is satisfactory. This series of processes increases the operation time, surgical trauma, and blood loss, and requires repeated use of the C-arm X-ray machine for fluoroscopy operations, which makes patients and medical staff absorb too much X-rays, which is extremely difficult. Great harm to the health of patients and medical staff
