A tibial tubercle traction device for patients with osteoporosis

Abstract

The present invention relates to a tibial tuberosity traction device for patients with osteoporosis, which comprises a traction arch, a first traction pin and a second traction pin; the second traction pin is arranged below the first traction pin, and A traction needle is arranged crosswise in the horizontal direction to form a preset horizontal angle a; the traction bow is connected to the first traction needle, and an adjustable length is provided between the first traction needle and the second traction needle. There are two adjustment rods; the adjustment rod is provided with a universal ball, and the adjustment rod is rotatably connected with the first traction needle and / or the second traction needle through the universal ball. The invention has the advantages of simple structure, reasonable design and convenient use, is suitable for patients with osteoporosis, can prevent the loosening of traction needles, relieve pain of patients, and enhance the traction effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tibial tubercle traction device for patients with osteoporosis. Background technique [0002] Osteoporosis is a widespread disease characterized by decreased bone density and increased bone fragility, leading to an increased risk of fractures. Hip fracture is the most serious complication of osteoporosis, and its incidence has tripled in Asian countries over the past 30 years. Tibial tubercle traction as a treatment for hip fractures can relieve pain caused by displacement of fracture ends and maintain fracture reduction. It is an important means to reduce tibial fractures and restore the length of lower limbs. During traction, first tighten the skin backward and upward to determine the two needle penetration points on the lateral side of the tibial tubercle, and then drill the traction needle (usually a Steiner's needle) from the outside to the inside perpendicular to...

Problems solved by technology

[0003] However, because the patient has osteoporosis and the hardness of the traction pin is higher than that of bone, continuous traction is likely to cause the enlargement of the traction pin hole and the loosening of the traction pin. The traction pin slides at the tibial traction, which increases the pain of the patient and reduces the increased the traction effect, and significantly increased the risk of infection

Medical care usually prevents the traction needle from slipping by adding barriers to the skin and the traction bow, such as bandages, adhesive tape, etc., but the effect is not good
