Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a postoperative fixation device for intertrochanteric fractures of the femur. Background Technology

[0002] Intertrochanteric fracture of the femur, also known as an intertrochanteric fracture, is an extra-capsular fracture and a common type of fracture in the elderly. Surgery is required after a fracture to fix the fracture ends, allowing the patient to recover as soon as possible and reducing the occurrence of complications.

[0003] For a period of time after surgery, patients need to rest in bed for extended periods, and their thighs need to be immobilized to prevent displacement of the fracture site, which would hinder recovery. Current immobilization methods use slings, but this method is ineffective, and the position and angle cannot be easily adjusted.

[0004] In conclusion, it is necessary to design a fixation device for intertrochanteric fractures of the femur to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing fixation slings used after intertrochanteric fracture of the femur have poor fixation effect and are inconvenient to adjust the angle and position. A new fixation device for intertrochanteric fracture of the femur is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides a fixation device for postoperative fixation of intertrochanteric fracture of the femur, including: a fixation strap and a leg fixator. The leg fixator includes a thigh fixation arm and a lower leg fixation arm connected by a hinge. The fixation strap is fixedly connected to the end of the thigh fixation arm away from the lower leg fixation arm. A sponge pad is attached to the inner side of both the thigh fixation arm and the lower leg fixation arm. Velcro straps are provided on both the thigh fixation arm and the lower leg fixation arm. A rotating head is connected to the outer side of both the thigh fixation arm and the lower leg fixation arm, and a collar is fixedly provided on the rotating head.

[0007] In a preferred embodiment of this solution, one end of the fixing strap is fixed to the thigh fixing arm, and a hook and loop fastener is provided on it, while the other end is provided with a hook and loop fastener.

[0008] In a preferred embodiment of this solution, the thigh fixation arm and the calf fixation arm are arc-shaped plate structures, with a sponge pad attached to the inner wall of the arc-shaped plate, and multiple ventilation holes are provided thereon.

[0009] Furthermore, the rotating head includes a fixed head fixed to the arc-shaped plate, and a rotating block is provided inside the fixed head. The top of the rotating block protrudes out of the fixed head and is connected to a collar.

[0010] Furthermore, the two collars are fixed together by an interlaced straight rod.

[0011] In a preferred embodiment of this solution, the hinge includes a fixing bolt, a pad, an upper connector, and a lower connector fitted on the fixing bolt. Both ends of the fixing bolt are tightened with bolt heads. The upper connector is connected to the thigh fixing arm, and the lower connector is connected to the calf fixing arm.

[0012] Implementing this utility model has the following beneficial effects:

[0013] This fixation device for intertrochanteric fractures of the femur can be used not only to prevent movement of the fracture site during bed rest after fracture surgery, but also to assist patients in walking after the recovery period, providing stable support. The thigh fixation arm is close to the outside of the thigh and is secured with Velcro straps to prevent displacement of the fracture site. The position of the thigh fixation arm and the lower leg fixation arm, connected by a hinge, can be adjusted to accommodate the patient's lower leg position. Attached Figure Description
