Description

Reduction fixing and binding belt for fracture of lesser trochanter of femur

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, concretely relates to femoral lesser trochanter fracture reduction fixation binding belt.

Background

Intertrochanteric femoral fracture is one of the most common fractures, and is common to the elderly and is accompanied by lesser trochanter fracture of the femur. In recent years, with the wide development of various internal fixation operations and the improvement of the diagnosis and treatment level of concurrent diseases in the perioperative period, the mortality rate is greatly reduced, but complications such as hip varus, nail plate fracture, femoral head and neck cutting, lower limb shortening and the like still exist. To prevent or reduce the above complications, importance of reduction and fixation of the lesser trochanter of femur has been increasingly emphasized.

Fracture of lesser trochanter of femur, because of local ligament attachment, reduction is difficult, and fixation is not firm, bring very big vexation to the operating doctor. In the past, the reduction under direct vision causes the detachment of the attached ligament, large trauma and partial function loss.

In the existing operation, most of the simple poking tools restore the fracture-displaced femoral lesser trochanters, and then fix the femoral lesser trochanters by screws after drilling, or transversely drill holes and then tie the fracture parts of the lesser trochanters by metal wires through the drill holes for fixing, or directly tie the holes on the femurs by the metal wires. Because the lesser trochanter is located at the back side of the femur and is the dead point of the iliocostalis, more muscles are covered around the lesser trochanter. The operation method needs to cut a large area of muscle, increases the wound and bleeding amount of a patient, has higher difficulty in resetting the fracture-displaced lesser trochanter of the femur, is easy to loosen the lesser trochanter and displace again, is difficult to maintain the integrity of the proximal medial column of the femur, and is easy to lose efficacy in the internal fixation of the fracture between the lesser trochanters of the femur; meanwhile, the fixation with the screw is not firm and has large wound due to osteoporosis; secondary damage is easily caused by bundling the drilling metal wires, and the small rotor is cut off by the metal wires; when the metal wire is directly bound on the outer surface of the small rotor, the operation of penetrating the metal wire into the periphery of the small rotor is difficult, and the metal wire is easy to slide off from the outer surface of the small rotor and cannot play a role in fixing; meanwhile, after the two metal wires are bundled, the blood circulation on the femoral shaft femoral membrane is not smooth, the healing of the wound is affected, and the tissue necrosis at the position is possibly caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a fixed binding area that resets is fractured to femur lesser trochanter is provided, a structure is simple, when being used for the fixed operation that resets of fracture of femur lesser trochanter, can reduce muscle incision face, alleviate patient's wound, use its convenient operation, only need to lead in through the hollow metal wire director of wicresoft, both ends tighten up fixedly can, effectively guarantee after the operation that the lesser trochanter can not cause displacement once more because of becoming flexible, improve the success rate of operation, and is with low costs, reduce patient's operation expense.

Realize the utility model discloses the technical solution of purpose does: the utility model provides a reduction of little trochanter fracture fixes and ties area which characterized in that: the metal wire fixing sleeve comprises a plurality of metal wires, wherein the front end and the rear end of each metal wire are woven to form a binding band, and the middle of each metal wire is woven to form a fixing sleeve ring.

Further, the binding band is formed by twisting all the metal wires into one strand, and the fixing ring is formed by twisting the metal wires in the middle into two strands.

The metal wire is made of a peptide alloy material.

The diameter of each metal wire is 0.1-0.4 mm.

The diameter of the binding band is 1.2-1.5 mm.

The binding belt is provided with a locking buckle, the locking buckle comprises a main body, the main body is provided with two axial through holes, the inner side of the main body is provided with four claws, and the binding belt is matched with the two through holes in a one-to-one mode at two ends.

The cross section of the main body is arc-shaped.

The utility model relates to a thighbone lesser trochanter fracture reduction fixation binding area has following beneficial effect: the minimally invasive hollow metal wire guiding device is simple in structure and convenient to use and operate, and only needs to be guided in through the minimally invasive hollow metal wire guiding device, and two ends of the minimally invasive hollow metal wire guiding device are tightened and fixed; when the reduction fixing device is used for reduction fixing operation of femoral lesser trochanter fracture, the muscle incision surface is greatly reduced, the influence on ligaments attached to the lesser trochanter is small, and the wound of a patient is relieved; the small rotor is surrounded by the fixed lantern ring up and down and is contacted with cortex, so that the small rotor is effectively prevented from displacing again due to looseness after the operation, the small rotor is prevented from being cut, and the success rate of the operation is improved; the contact part of the bandage and the femoral shaft is in a thread shape, namely point contact, the contact surface is limited, and the influence on the blood running of the femoral shaft is small; the locking buckle is adopted to fix the binding band, so that the operation is convenient, the fixation is reliable, and the fracture of the binding band is effectively avoided; the production cost is low, and the operation cost of the patient is effectively reduced.
