Description

A kind of bone traction steel needle with rubber stopper

technical field

The utility model relates to the technical field of bone traction steel needles, in particular to a bone traction steel needle with a rubber plug.

Background technique

Bone traction steel needle is a commonly used internal fixation material in orthopaedics. It is used to fix short fractures or avulsion fractures and other fractures with little stress. It is also often used in the fixation of temporary fracture fragments in orthopaedic surgery. Most of the bone traction steel needles have a simple structure. After the steel needle passes through the affected limb, the two ends of the steel needle are sharp. In clinical practice, the used injection glass bottle is sheathed at both ends of the steel needle to avoid stabbing the patient and family members. On the one hand, the glass bottle for injection is easy to break, and on the other hand, there are drug residues that can easily lead to the risk of infection. Second, after the steel needle penetrates the affected limb, the wound is exposed and easily exposed to the outside world. The wound covers the function of preventing infection. In addition, the steel needle passes through the affected limb. Because the surface of the steel needle is smooth, once it is pulled out, it is easy to slip off once it is not clamped, causing pain to the patient.
