Locating assisting device for femoral neck fractures and use method of locating assisting device

Abstract

The invention discloses a locating assisting device for femoral neck fractures. The locating assisting device comprises a base, a frame, a square aiming block, a fixing column A and a fixing column B, wherein the frame is perpendicularly arranged on the base and can rotate around a longitudinal axis of the frame in the plane of the base; the fixing column A is fixed at the top end of the frame; the square aiming block is erected on the frame through a rotating shaft, can move freely in sliding grooves formed in two sides of the frame, can be fixed to any position and can also rotate around the rotating shaft; a plurality of locating holes are formed in the surface of the square aiming block, and the fixing column B is detachably fixed in the center of the surface with the locating holes. The locating assisting device can shorten operation time, reduce operation wounds, reduce bleeding amount, reduce damage to femoral neck bones, reduce radioscopy times and reduce radiation to patients and medical workers.

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 ...

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
