Problems solved by technology

But there are some deficiencies in the existing calcaneal traction treatment of lower extremity fractures. Because the traditional Stud nails are smooth throughout, for patients who are older, osteoporosis or have a longer traction time, the traditional Stud nails are easy to Loosening, even slipping out, leading to changes in the traction line, affecting the healing of fractures, leading to the formation of skin pressure sores and nail tract infection, etc., which brings a lot of inconvenience to clinical work

Embodiment

[0016] Embodiment: An anti-slip bone traction needle, comprising a needle body 1 with anti-slip lines 2 on the surface of the needle body.

[0017] The anti-slip lines are located on the surface of the middle section of the needle body.

[0018] The anti-slip pattern is engraved on the smooth surface of the needle body and does not exceed the smooth surface of the needle body. The engraved anti-slip pattern saves material and is convenient for processing.

[0019] The anti-slip pattern is several rhombuses. Tests have proved that the anti-slip effect of the diamond pattern is the best, and can effectively resist the force from various irregular directions to loosen the needle body.

[0020] The needle body has a self-tapping tip 3 .

[0021] The cross-section of the needle body is circular, and its diameter is 4 mm.

[0022] The length of the needle body is 20 cm.

[0023] The length of the anti-skid lines is 5 cm.

Abstract

The invention discloses a skid-resistance bone traction needle, comprising a needle body, wherein skid-resistant grains are formed on the surface of the needle body. In the skid-resistance bone traction needle, one section of skid-resistant grains are engraved on the original smooth needle body, so that the skid-resistance bone traction needle can be better fixed, thus the needle body can be effectively prevented from loosening and sliding out, the traction strength and direction can be kept unchanged, the fracture healing is accelerated and the pressure ulcer and the pin track infection of skin can be effectively prevented.

Description

technical field [0001] The invention relates to a structural improvement of a medical device, in particular to a structural improvement of a Stud nail for bone traction treatment. Background technique [0002] Stud nail is a commonly used medical device in orthopedic surgery, and is often used in calcaneal traction surgery. In clinical practice, calcaneal traction has become the most commonly used preoperative treatment method for calf fractures. It can maintain the fracture line, relieve pain, and facilitate swelling. But there are some deficiencies in the existing calcaneal traction treatment of lower extremity fractures. Because the traditional Stud nails are smooth throughout, for patients who are older, osteoporosis or have a longer traction time, the traditional Stud nails are easy to Loosening, or even slipping out, leads to changes in the traction line, affects the healing of fractures, leads to the formation of skin pressure sores and nail tract infection, etc., wh...
