Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] A broken intramedullary nail removal component, such as Figure 1-Figure 3 As shown, it includes: a guide tube 3 inserted into the medullary cavity along the fracture, a pull tube 4 that can pull the distal broken nail 2; the pull tube 4 is sleeved in the guide tube 3; the guide tube 3 includes :
[0031] Two fixed sections 302 and two curved sections 301, one fixed section 302 connected to one curved section 301 form a group, and there is an intermediate section 303 connected to two curved sections 301 at both ends;
[0032] The two ends of the guide tube 3 are divided into a first end close to the broken nail in the medullary cavity and a second end far away from the broken nail in the medullary cavity. The curved section 301 is an expansion sleeve made of elastic material. The first end of the two curved sections 301 Each end is c...

The invention discloses a broken intramedullary nail taking-out assembly and a using method thereof. The broken intramedullary nail taking-out assembly comprises a guide tube entering a medullary cavity along fracture treatment and a traction tube capable of pulling a broken nail at the far end. The traction tube is sleeved in the guide tube; the guide pipe comprises two fixed sections and two bent sections, one fixed section is connected with one bent section to form a group, and the guide pipe is provided with a middle section, and two ends of the middle section are respectively connected with the two bent sections; the two ends of the guide tube are divided into a first end close to a broken medullary cavity nail and a second end far away from the broken medullary cavity nail, the bending sections are elastic tube bodies, and the first ends of the two bending sections are connected with direction control line groups respectively; the direction control line group consists of a plurality of rope bodies and is used for controlling the bending angle of the bending section; the front end of the traction tube is provided with a connecting assembly detachably connected with a far-end broken nail. The problem that an existing intramedullary far-end broken nail is not easy to take out is solved.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a broken intramedullary nail removal assembly. Background technique [0002] Fracture is a common surgical injury. Reduction, fixation, and healing are the trilogy of fracture treatment, and fixation is the connecting link between reduction and healing. Good fixation not only consolidates the reduction effect, but also promotes the speed and quality of healing. Strong fracture fixation can reduce the pain of the wounded, prevent the aggravation of the injury, prevent shock, protect the inner soft tissue, prevent further damage to blood vessels and nerves, facilitate clinical care, and minimize the disability rate. [0003] The intramedullary nail is an orthopedic internal fixation medical device commonly used in the treatment of extremity fractures. The locking screw hole is provided with a longitudinal groove on the surface of the intramedullary nail rod. ...
