Further, a handle is sleeved at the lower end of the movable arm.
Furthermore, the U-shaped arm, the connecting rod and the movable arm are made of medical stainless steel.
Since the technical scheme is used, the utility model discloses an advantage has below: the utility model discloses can make art person guide steel wire or titanium cable under the non-direct-view in small incision to walk around fracture piece and diaphysis and draw forth extracorporeally, can effectively shorten the hand time after using this apparatus, reduce the blood loss volume promptly, reduce the operation incision and to the damage of soft tissue around the fracture, be favorable to union. Therefore, the utility model discloses simple structure, low cost, simple to operate can improve staff's work efficiency greatly, make things convenient for medical staff's operation, and convenient cleaning and disinfection has apparent social.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The embodiment of the utility model provides a: referring to fig. 1 to 4, a minimally invasive steel wire or titanium cable guider for orthopedic surgery comprises a U-shaped arm 1.1, a connecting rod 1.2, a movable arm 2 and a steel wire or titanium cable 3, wherein the U-shaped arm 1.1 connected with the connecting rod 1.2 into a whole is arranged at the upper end of the connecting rod 1.2, U-shaped grooves 1.4 are symmetrically formed at the upper ends of the left arm and the right arm of the U-shaped arm 1.1, the movable arm 2 is erected between the U-shaped grooves 1.4 of the left arm and the right arm, a left pin 2.1 and a right pin 2.4 are respectively and fixedly connected to the left end and the right end of the movable arm 2, a vertically arranged screw hole and a fixed hole 2.2 are respectively formed at the end part of the right end of the movable arm 2, the screw hole is communicated with the fixed hole 2.2, a locking screw 2.3 is connected to an internal thread, the steel wire or titanium cable 3 is inserted into the fixed hole 2.2, a chute 1.12 is formed at the inner side of the upper end of the left arm, the chute 1.12 is, the top of the right arm is provided with a limit groove 1.13, and the left pin 2.1 and the right pin 2.4 are respectively clamped in the chute 1.12 and the limit groove 1.13.
