Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a fixing and traction device for lower limb fractures. Background Art

[0002] Calf plaster fixation and calcaneal traction are commonly used techniques in orthopedics, mainly suitable for calf fractures, unstable tibial fractures, fibula fractures, tibial plateau fractures, ankle comminuted fractures, and pilon fractures. This technology is of great significance for preoperative fracture reduction, reducing the difficulty of reduction during surgery, and reducing sequelae such as poor healing of surgical fractures, malformation of healing, and poor surgical reduction, and is prepared for surgery. Although the fixation and traction technology has been widely used in orthopedics, the existing calcaneal traction device has a traditional structure, inconvenient use, large space occupation, and makes the patient's calf uncomfortable to place, which adds additional wound surface and medical expenses to the patient. However, simple preoperative calf plaster fixation will have the disadvantage of improper external placement, such as the affected limb is in an external rotation position, resulting in dislocation of the fracture ends, increased pain in the patient, and passive long-term external rotation of the lower limbs, which can damage the common peroneal nerve.

[0003] Currently, early clinical treatment is to protect the surrounding soft tissue by stabilizing the fracture, such as calcaneal traction, brace fixation and external fixator fixation. Therefore, in response to the above technical problems, the utility model proposes a new micro reduction and traction fixation device, which provides a small, light and simple design direction for the traction and fixation device for patients' lower limb surgical rehabilitation and preoperative reduction and fixation of patients. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a fixing and traction device for lower limb fractures.

[0006] Through the above technical solution, the fixing grooves opened on the surface of the splint can enable medical staff to cooperate with the traction rope to fix the entire device at one end of the bed, thereby increasing the stability of the device when it is fixed.

[0007] As a further improvement of the above solution, the leg fixing ropes are symmetrically distributed with the calf fixing frame as the center, the fixing plates are symmetrically distributed with the foot placement plate as the center, and the fixing grooves are symmetrically distributed with the splint as the center.

[0008] As a further improvement of the above solution, the connecting rod is located at the top of the supporting base plate, the foot cover body is located at the top end of the supporting base plate, and the foot cover body is located at the front side of the calf fixing frame.

[0009] As a further improvement of the above solution, the foot cover body is located in front of the leg fixing rope, the heating plate is located at the rear end of the foot cover body, and the heating plate is located on the rear side of the foot sole placement plate.

[0010] Through the above technical solution, the heating plate heats the object by converting electrical energy into thermal energy, which is a form of electrical energy utilization.

[0011] As a further improvement of the above solution, the extension rods are symmetrically distributed with the foot placement plate as the center, the connecting rods are symmetrically distributed with the foot placement plate as the center, the extension rods are located on the front side of the foot cover body, and the extension rods are located at the top end of the rotating shaft.
