Problems solved by technology
[0002] Kirschner wires are widely used in orthopedic surgery, especially in the replantation of severed fingers (toes) in hand and foot surgery, and are the preferred internal fixation materials. However, the disadvantage of the current clinically used Kirschner wires is that only one tip can Penetrate into the bone. In the replantation of the severed finger (toe), the broken end of the bone is often trimmed for alignment. Internal fixation is possible, but due to the large resistance, the Kirschner wire is easy to float, which often causes alignment deviation, finger (toe) rotation, etc. during fixation; The tail end of the needle is cut obliquely to penetrate into the distal bone in a reverse direction, and then penetrate into the proximal bone after alignment, but it often takes more time and effort

Embodiment Construction
[0009] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0010] see figure 1 , the embodiment of the present invention includes:
[0011] A double-ended Kirschner wire, comprising: a needle bar 1; a needle head 2 is provided at both ends of the needle bar 1; a scale 3 is arranged on the outer surface of the needle bar 1; and the needle head 2 is in the shape of a triangular pyramid.
[0012] When in use, step 1, reversely penetrate the needle 2 at one end of the Kirschner wire from the fracture into the distal bone; step 2, perform alignment at the fracture; step 3, insert the needle at the other end of the Kirschner wire 2 Penetrate into the proximal bone to complete the internal fixation of the brok...

The invention discloses a double-head kirschner wire which comprises a wire rod. Wire heads are arranged at the two ends of the wire rod respectively. Scales are arranged on the outer side face of the wire rod. By means of the mode, the length, punctured into the fracture, of the kirschner wire can be controlled, and the point of the kirschner wire is prevented from puncturing skin; internal fracture fixation is carried out efficiently and fast, and operation time is effectively shortened.
Description
technical field [0001] The invention relates to a medical device, in particular to a double-sided device capable of controlling the length of the Kirschner wire piercing into the fracture, preventing the needle tip of the Kirschner wire from piercing the skin, efficiently and quickly performing internal fixation of the fracture, and effectively shortening the operation time. Head Kirschner wire. Background technique [0002] Kirschner wires are widely used in orthopedic surgery, especially in the replantation of severed fingers (toes) in hand and foot surgery, and are the preferred internal fixation materials. However, the disadvantage of the current clinically used Kirschner wires is that only one tip can Penetrate into the bone. In the replantation of the severed finger (toe), the broken end of the bone is often trimmed for alignment. Internal fixation is possible, but due to the large resistance, the Kirschner wire is easy to float, which often causes alignment deviation...
