Problems solved by technology

[0006] 1. First of all, it is difficult to locate the entry point of the screw guide pin. Over-adjustment may occur when the screw guide pin is adjusted, resulting in repeated fluoroscopy and repeated positioning, which increases the amount of fluoroscopy, prolongs the operation time, and increases the local pain. Bleeding, increasing patient trauma

Embodiment Construction

[0023] figure 1 It is a perspective view of a preferred embodiment of the locator according to the present invention, figure 2 for figure 1 3D exploded view of the locator. refer to figure 1 , 2 As shown, the femoral neck fracture hollow screw internal fixation guide pin locator provided by the present invention includes: a fixing rod 10, a three-point positioning frame 20, a first pivotal part 30, a second pivotal part 40 and a The third pivot portion 50 .

[0024] Wherein, one end of the fixing rod 10 is tapered, and an electric drill is used for fixing and positioning on the femoral shaft during the operation. The first pivotal portion 30 is connected to the middle of the fixed rod 10 , and then in turn, the second pivotal portion 40 is connected to the third pivotal portion 50 , and the third pivotal portion 50 is connected to the three-point positioning frame 20 .

[0025] The three-point positioning frame 20 includes a trident-shaped frame body, and the three bran...

Abstract

The invention provides a hollow screw internal fixation guide pin positioner for femoral neck fracture, comprising a fixing lever for supporting and positioning the positioner on a femur; a three-point positioning rack including a rack body, three positioning levers and a connection lever; a first pivoting section pivoted on the fixing lever; a second pivoting section pivoted on the first pivoting section; a third pivoting section pivoted on the second pivoting section and pivoted on the connection lever of the fixing rack. According to the technical scheme above, the fracture positioner can adjust positioning position and angle direction, can overcome defects of being difficult to fix and unable to be observed under flouroscopy of the conventional fixing device, also can conveniently and quickly position femoral neck fracture accurately, and once successful positioning can be obtained. By driving the screw guide pin into the femoral neck through a center hole of the positioning lever, repeated positioning is avoided, shortened surgery time, reduced partial hemorrhage, reduced sclerotin quality reduction, and increased fixing strength for the femoral neck are obtained.

Description

technical field [0001] The invention relates to a fracture locator, in particular to a locator used for locating a hollow screw internal fixation guide pin for a femoral neck fracture during a femoral neck fracture treatment operation. Background technique [0002] Femoral neck fractures have become a relatively common orthopedic disease, and a lot of manpower, material and financial resources are spent on related treatments every year. At present, bed rest and other conservative treatment methods can usually be used for incomplete femoral neck fractures, and surgical treatment should be considered for non-displaced complete fractures and displaced fractures, unless the patient has obvious surgical contraindications. For fully displaced femoral neck fractures, total hip replacement or hemiarthroplasty is considered to be an ideal method due to the high probability of malunion of femoral neck fractures and avascular necrosis of the femoral head. However, open reduction and i...
