Problems solved by technology

When using this kind of intramedullary nail, it is necessary to connect and fix the distal and proximal ends with locking nails. When installing the intramedullary nail, place the intramedullary nail into the medullary cavity and then drill the hole. The position of the locking nail hole on the inner nail increases the burden of the doctor's operation

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as Figure 1-4 As shown, the magnetic intramedullary nail of the present invention includes a nail body 1. The nail body 1 is a long-axis tube with a through hole inside. When the magnetic intramedullary nail is used, a wound is opened at one end of the bone. The nail body 1 is inserted into the medullary cavity from the wound, the end of the nail body 1 close to the wound is the proximal end, and the end of the nail body 1 far away from the wound is the distal end.

[0020] The proximal and distal ends of the nail body 1 are provided with a plurality of locking nail holes 2 arranged radially along the nail body 1, and the locking nail holes 2 are through holes. In this embodiment, the locking nails at the proximal and distal ends The number of holes 2 is two. The nail body 1 includes an integrally formed body 11 and a c...

Abstract

The invention relates to the field of medical apparatuses and instruments, in particular to a magnetic intramedullary nail. The magnetic intramedullary nail comprises a nail body, wherein the nail body is a long axis tube provided with through holes inside, multiple nail locking holes formed in the radial direction of the nail body are formed in the near end and the far end of the nail body, and a magnetic piece for positioning the nail locking holes in the far end is embedded in the far end of the nail body. According to the magnetic intramedullary nail, the magnetic piece is arranged at the far end of the intramedullary nail, the distance between the magnetic piece and each nail locking hole in the far end is fixed, so that the nail locking holes in the far end can be accurately positioned according to the position of the magnetic piece, and great convenience is brought to a doctor.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a magnetic intramedullary nail. Background technique [0002] Currently, intramedullary nails, steel plates, external fixators, etc. are usually used in the surgical treatment of long tubular bone shaft fractures. The locking nail can pass through the long tube cortex and the distal and proximal locking nail holes on the intramedullary nail to achieve the locking effect. It has the functions of aligning the fracture fragments, fixing them, and supporting a certain gravity to facilitate the growth of the callus. Fractures healed. To use this type of intramedullary nail, it is necessary to connect and fix the distal and proximal ends with locking nails. When installing the intramedullary nail, place the intramedullary nail into the medullary cavity and then drill the hole. It is impossible to find the corresponding marrow at the distal end of the long cortical bone. The positio...
