Tibial tuberosity traction device for osteoporosis patient

Abstract

The invention relates to a tibial tuberosity traction device for an osteoporosis patient. The tibial tuberosity traction device comprises a traction bow, a first traction needle and a second tractionneedle. The second traction needle is arranged below the first traction needle and is crossed with the first traction needle in the horizontal direction to form a preset horizontal included angle a. The traction bow is connected with the first traction needle, and two adjusting rods with the adjustable length are arranged between the first traction needle and the second traction needle. Universalballs are arranged on the adjusting rods, and the adjusting rods are rotatably connected with the first traction needle and / or the second traction needle through the universal balls. The tibial tuberosity traction device is simple in structure, reasonable in design, convenient to use, suitable for osteoporosis patients and capable of preventing the traction needle from loosening, relieving pain ofthe patients and enhancing 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 prevalent 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 doubled or tripled in Asian countries over the past 30 years. As a treatment method for hip fractures, tibial tuberosity traction can reduce the pain caused by the displacement of the fractured end and maintain the reduction of the fracture. It is an important means to reduce tibial fractures and restore the length of the lower limbs. During traction, first stretch the skin back and up, determine the two needle penetration points on the outside of the tibial tubercle, and then drill the traction needle (usually a Steiner wire) from outside to insi...

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
