Problems solved by technology

[0004] However, the current fracture surgery method has a large incision wound and a lot of soft tissue damage, so the infection rate is high, the postoperative wound pain is obvious, and the operation process takes a long time. Rehabilitation, resulting in longer hospital stays and higher medical costs

Embodiment 1

[0035] The bone fixation device 100 of the present invention includes a positioning mechanism 1 , two threading mechanisms 2 and a needle threading mechanism 3 .

[0036] The positioning mechanism 1 includes a body 11 and two engaging portions 12 , the engaging portions 12 are disposed in the body 11 , and each engaging portion 12 has an orienting member 121 . In this embodiment, a plurality of anti-slip portions 111 are formed on the surface of the main body 11 . The joint portion 12 is an insertion slot, and the orientation member 121 is a concave body disposed on the inner wall of the insertion slot.

[0037] Each threading mechanism 2 includes a hollow tube 21 for threading a thread body and a corresponding orientation member 22 . In this embodiment, the hollow tube 21 has two openings 211 , 212 . The corresponding orientation piece 22 is a protrusion disposed on the outer surface of the hollow tube 21 , and the corresponding orientation piece 22 is correspondingly engag...

Embodiment 2

[0045] like Figure 7 It is a perspective view of Embodiment 2 of the bone fixation device of the present invention. The bone fixation device 100a of this embodiment is substantially the same as the bone fixation device 100 of Embodiment 1, so these parts will not be described in detail, and the same components are represented by the same symbols. The mechanism 3a is integrally formed with the body 1a. And the hollow tubes 21a of the two threading mechanisms 2a are not docked, as long as the openings 211a at one ends of the hollow tubes 21a of the two threading mechanisms 2a correspond to each other directionally. The perforation 31a of the needle threading mechanism 3a is designed to be wider than the perforation 31 of the bone fixation device 100 so that multiple needles P2 can pass through, and the direction in which the needles P2 pass through is in a different direction from the extending path of the perforation 31a, such as Figure 8 shown.

Abstract

The invention provides a skeleton fixing device. The skeleton fixing device comprises a positioning mechanism, two threading mechanisms and a needle threading mechanism; the positioning mechanism comprises a body and two connection portions which are arranged inside the body; every connection portion is provided with a positioning part; every threading mechanism comprises a hollow pipe which is for a thread to penetrate and a corresponding orienting part; the corresponding orienting part and an orienting part are in corresponding snap-fit; the needle threading mechanism which is arranged on the surface of the body in a snap-fit mode is provided with a penetration hole; the extension path of the penetration hole and the extension paths of the hollow pipes are in different height surfaces. The skeleton fixing device has the advantages of being simple in operation and reliable indeed, reducing the size of the wound and improving the operation efficiency.

Description

technical field [0001] The invention relates to an operation device, in particular to a bone fixation device. Background technique [0002] The incidence of fractures is quite high, which is usually due to accidents, sports injuries, repeated pressure accumulation, bone lesions and other conditions that cause bones to break or rupture. Fractures can be divided into closed fractures and open fractures. Closed fractures refer to the fracture site not in contact with the outside of the human body, and open fractures refer to the fracture site in contact with the outside of the human body. In the treatment of fractures, the broken bones are usually connected and fixed to help the natural healing between the broken bones. Among them, using bone nails to connect broken bones through surgical operations is a common fixing method. [0003] The fracture fixation method of traditional orthopedic surgery requires cutting the soft tissue around the bone for further implantation of bon...
