Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1 and 2, the present embodiment provides an orthopedic minimally invasive steel wire guide, which aims to solve the technical problem that the existing steel wire guide cannot meet the requirements of guiding some conditions, and therefore, the orthopedic minimally invasive steel wire guide provided by the present embodiment includes a handle 1 and a hollow tube 2 having one end fixedly mounted on the handle 1, and an arc guide 3 is disposed at one end of the hollow tube 2 away from the handle 1, where the above structure is a conventional structure, so that in the present embodiment, detailed description is not given, the present embodiment focuses on an improvement of the present embodiment on the arc guide 3, in the present embodiment, a conventional integral arc guide 3 is divided into two parts, so that the arc guide can be further extended, and further, the end of the arc guide 3 can be exposed, and for this purpose, the arc guide 3 provided by the present embodiment includes a guide body 31 having a semicircular cross section and a sliding part disposed on the guide body 31, and therefore, in order to achieve the above purpose 32, wherein the cross section of the sliding member 32 is also semicircular, so that the guide body 31 and the sliding member 32 constitute the existing arc-shaped tubular structure, of course, one end of the guide body 31 is fixedly connected with the hollow tube 2. In the present embodiment, the sliding of the sliding member 32 relative to the guide body 31 is mainly provided with a sliding groove on the surface of the guide body 31 opposite to the sliding member 32, and the sliding member 32 is provided with a sliding protrusion matching with the sliding groove. Here, when necessary, the sliding groove extends from one end of the guide body 31 to the other end and penetrates through the end of the other end, so as to separate the sliding member 32 from the guide body 31, it is known that after the steel wire is guided by the conventional steel wire guide, the steel wire needs to be cut first, and then the steel wire guide can be taken down.

Considering that the slider 32 needs to slide, it is not appropriate to provide the wire inlet 21 at the arc guide 3, and for this reason, in the present embodiment, the wire inlet 21 is provided at the end of the hollow tube 2 near the arc guide 3, so that the movement of the slider 32 does not have any influence on the wire.

Considering that the slider 32 is pressed against the periosteum when sliding, the guide body 31, for which reason the slider 32 may be inserted into the muscle and not be slid against the bone, in the present embodiment, a guide tube 33 is provided at an end of the slider 32 remote from the hollow tube 2.
