Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment: Please refer to Figures 1-5 , an orthopedic wire guide, including a guiding tube 1, a second guiding tube 2 is arranged at one end of the guiding tube 1, a handle 3 is arranged at the bottom of the guiding tube 1, notches 5 are penetrated through both ends of the handle 3, the guiding tube 1 and the second guiding tube 2 are relatively arranged in the inner cavity of the notch 5 by using a rotating shaft 4, openings 6 are arranged on one side of the guiding tube 1 and the second guiding tube 2, a guiding cylinder 7 is arranged inside the guiding tube 1, a moving groove 15 is arranged on the right side of the guiding tube 1 and the second guiding tube 2, a moving column 8 is arranged in the inner cavity of the moving groove 15, a fastening column 9 is arranged inside the moving column 8, a screw rod 10 is threadedly connected in the inner cavity of the fastening column 9, a knob 11 is arranged on one side of the moving column 8, a clamping mechanism 12 is arranged inside the handle 3, and a limiting mechanism 13 is arranged at the bottom of the clamping mechanism 12.

[0023] Furthermore, there is a small friction force between the guiding cylinder 7 and the guiding tube 1, and the moving column 8 is fixedly connected with the guiding cylinder 7.

[0024] Further, the fastening post 9 penetrates through the moving post 8 into the inner cavity of the guiding cylinder 7. The screw rod 10 penetrates through the moving post 8 and a bearing is fixed at the junction for limiting. The screw rod 10 is fixed to the inner ring of the bearing, and the knob 11 is fixedly connected to the screw rod 10. After the guiding tube 1 and the second guiding tube 2 are combined, the wire opening 6 is inserted into the guiding cylinder 7. By rotating the knob 11 and cooperating with the screw rod 10 and the fastening post 9, the wire is fixed in the guiding cylinder 7. In cooperation with the moving post 8 in the moving groove 15, the guiding cylinder 7 is rotated to the opening 6 of the second guiding tube 2, realizing rapid guiding and surrounding of the wire.

[0025] Further, the clamping mechanism 12 includes a second notch 124 opened at the top of the handle 3. A tapered block 121 is arranged in the inner cavity of the second notch 124. The bottom of the tapered block 121 is fixedly connected to a connecting rod 123. The bottom end face of the guiding tube 1 is provided with an inclined surface which fits with the inclined surface of the tapered block 121.

[0026] Further, a lifting block 122 is arranged in the inner cavity of the handle 3. Both ends of the lifting block 122 are located in the inner cavity of the notch 5. The lifting block 122 is fixedly connected to the connecting rod 123. After the guiding tube 1 and the second guiding tube 2 are placed in the patient's body from both sides of the bone surface, the thumb can press the lifting block 122 downward. Under the action of the notch 5 and the connecting rod 123, the tapered block 121 in the second notch 124 is driven to move downward. During the process, the inclined surface of the tapered block 121 contacts the bottom end faces of the guiding tube 1 and the second guiding tube 2, causing the guiding tube 1 and the second guiding tube 2 to gradually merge. In cooperation with the limiting mechanism 13, the guiding tube 1 and the second guiding tube 2 are merged and fixed, which can be operated with one hand and is convenient for subsequent guiding and surrounding of the wire.

[0027] Further, the limiting mechanism 13 includes two limiting buckles 131 fixed to one side of the handle 3. A guiding slope 132 is arranged on one side of the top of the limiting buckle 131.

The top and bottom of the spring 134 are respectively connected to the lifting block 122 and the bottom of the notch 5. When the lifting block 122 moves downward to merge the guiding tube 1 and the second guiding tube 2, under the action of the guiding slope 132, the limiting block 131 is offset by a certain angle and then clamps the lifting block 122. When releasing this guide, the limiting block 131 is toggled to one side. In cooperation with the spring 134 on the outer ring of the telescopic rod 133, the lifting block 122 automatically resets and the guiding tube 1 and the second guiding tube 2 separate by themselves.

[0028] Further, anti-slip strips 14 are arranged at the four corners of the handle 3, using the anti-slip strips 14 to increase the friction between the doctor and the handle 3 and improve the stability of this orthopedic wire guide during use.

[0029] Working principle: When using this orthopedic wire guide, hold the handle 3 and place the guide tube 1 and the second guide tube 2 into the patient's body from both sides of the bone surface. Combine the guide tube 1 and the second guide tube 2 with the clamping mechanism 12 and the limiting mechanism 13. Insert the wire opening 6 into the guide cylinder 7. Rotate the knob 11 and cooperate with the screw rod 10 and the fastening column 9 to fix the wire in the guide cylinder 7. Then, under the action of the moving column 8 in the moving groove 15, turn the guide cylinder 7 to the opening 6 of the second guide tube 2 to quickly guide and surround the wire, solving the problem that the existing orthopedic wire guide is difficult to quickly pass through the guide tube to complete the wire surrounding.
