Embodiment

[0018] like figure 1 , figure 2 As shown, the femoral neck fracture fixation and positioning device includes a positioning rod 10, two steel needles 2 and an adjuster. 1, the rod hole of the positioning rod 10 is arranged in the fixed block 7, and the positioning rod 10 can slide and fix up and down in the rod hole, and its fixing is realized by tightening the fixing knob 8; one side of the fixed block 7 adopts a shaft / The corresponding way of the hole is connected with a fixed plate 6 that can be rotated and fixed relative to the fixed block back and forth, and its fixing is realized by tightening the fixed knob 9; the fixed plate 6 is connected with the sliding plate 4 through the groove plate structure (see figure 2 ), the sliding plate 4 can be slid and fixed in the fixed plate 6, and its fixing is realized by tightening the fixing knob 5; A steel needle 2 can be placed in the pinhole. The steel needle 2 finally drives into the head of the femur 1 .

Abstract

The invention discloses a femoral neck fracture fixing and positioning device, and relates to an outer support for treating femoral neck fractures. The femoral neck fracture fixing and positioning device comprises a positioning rod, two steel needles and a regulator. The regulator is composed of a fixed block and a sliding and rotating block, wherein the sliding and rotating block can slide relative to the fixed block and / or rotate around the fixed block to be fixed. Two needle penetrating holes for the steel needles to penetrate in are formed in the sliding and rotating block. According to one structure of the sliding and rotating block, one end of a rotating block is movably connected with the fixed block and can rotate relative to the fixed block, a sliding block capable of sliding relative to the fixed block in the plane is arranged in the rotating block, and the two needle penetrating holes for the steel needles to penetrate in are formed in the sliding block; according to another structure of the sliding and rotating block, the sliding block is movably connected with the fixed block and can move relative to the fixed block in the plane, the rotating block is arranged in the sliding block, and the two needle penetrating holes for the steel needles to penetrate in are formed in the rotating block. The femoral neck fracture fixing and positioning device has the advantages of being easy and convenient to operate and capable of less adopting X-ray fluoroscopy and being accurately fixed at the optimal position.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and further relates to an aimer for treating fractures, especially an aiming fixation device for treating femoral neck bone fractures. Background technique [0002] In the process of fracture treatment, the treatment of femoral neck fracture is a difficult point. It is not easy to heal, and the requirements for screw fixation are high, especially for the elderly due to osteoporosis. If the position of the needle is not good, the nail is not firm, the screw fixation is difficult, and the fixation failure is easy to cause bone nonunion. Secondary joint replacement is often required, which increases physical pain and economic burden for patients. Therefore, in fact, for many patients with femoral neck fractures, it is required to drive two steel needles into the middle part of the femoral head and neck so as not to fail, which puts forward higher requirements for accuracy. In order to ...
