Problems solved by technology
[0002] In the reduction treatment of proximal femur and femoral shaft fractures, it is often necessary to keep the affected limb at a certain angle or to tilt outward or tilt inward. Traditional tractors cannot achieve angular traction and tilt due to their relatively large elasticity. Traction, currently clinically still uses the traditional traction frame combined with bundled support rods to achieve the therapeutic effect, the operation is very inconvenient, the accuracy is poor, and more importantly, the reliability is not good, which increases the risk of surgery and prolongs the operation time

Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing.
[0030] Loosen the tightening handle before the traction operation, put the T-shaped slot of the connecting clip on the T-shaped handle of the traction bed, tighten the tightening handle to complete the connection between the traction frame and the traction bed, and loosen the outer sleeve so that the front end of the traction frame It can be adjusted universally. The patient is on the traction bed. In order to achieve a good traction effect, the traction needle should be as perpendicular to the traction axis as possible. Hook the collet to the traction needle and lock it with a tight wire, adjust the traction angle, tighten the coat by hand to confirm the traction state, and then tighten the coat with the matching wrench to perform the traction operation.

The invention relates to a multifunctional traction repositor, belonging to the field of medical apparatuses and instruments. The multifunctional traction repositor consists of stopper screws (1), chucks (2), dowels (3), traction rods (4), stabilizing sleeves (5), locking pins (6), a fixed block (7), a ball head rack assembly (8) and connecting clamp assemblies (9). The multifunctional traction repositor is characterized in that knurling is formed on the tail part of each stopper screw (1); each chuck (2) is slotted in an L shape, wherein a screw hole is formed in the left end while a screw hole and a through hole are formed in the right end of each chuck; a step and a thread are arranged on the end part of each traction rod (4); the end part of each stabilizing sleeve (5) is in a conical surface structure with a through hole, wherein a thread is arranged in an inner hole in the right end of each stabilizing sleeve; the fixed block (7) is a step shaft, wherein an inner hole in the left end of the fixed block is spherical. The multifunctional traction repositor is connected with a traction table, and the diseased limb is connected with the multifunctional traction repositor for implementing a traction operation.
Description
technical field [0001] The invention relates to a multifunctional traction resetter, which belongs to the field of medical instruments. Background technique [0002] In the reduction treatment of proximal femur and femoral shaft fractures, it is often necessary to keep the affected limb at a certain angle or to tilt outward or tilt inward. Traditional tractors have relatively large elasticity and cannot achieve angle traction and tilt. For traction, traditional traction frames combined with bundled support rods are still used clinically to achieve the therapeutic effect. The operation is very inconvenient, the accuracy is poor, and more importantly, the reliability is not good, which increases the risk of surgery and prolongs the operation time. Contents of the invention [0003] The invention provides a multifunctional traction resetter with simple structure and convenient operation. [0004] Technical scheme of the present invention is as follows: [0005] The multifun...
