Technical Field

[0001] The present invention relates to the field of medical instruments, and more particularly to a tibia and fibula screw inserter. Background Art

[0002] A tibiofibular screw inserter is a surgical tool specifically designed to place screws between the tibia and fibula (the two main bones of the lower leg) to stabilize a fractured or unstable joint.

[0003] A Chinese patent with authorization announcement number CN 109875673 B describes a device for fixing an ankle joint. In a simulated operation, the resin chassis in the device cannot solve the imaging effect of blood stains during X-ray scanning, limiting the imaging effect of X-rays during surgery.

[0023] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present disclosure will be more comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0024] In addition, the described features, structures or characteristics may be combined in one or more example embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0025] Example 1

[0026] like Figure 1-5 A tibia and fibula screw inserter includes a bracket 1, a flushing member 2, and an X-ray transmitter 3. The bracket 1 is used to prop up the calf and ankle on a basis higher than the bed surface, the flushing member 2 is used to clean blood stains, and the X-ray transmitter 3 is used to take images of the patient's tibia, fibula, screws, etc. when necessary.

[0027] The support 1 is a plate body with four support columns fixed below the plate body. The support columns are arranged on the surface of the bed body to make the plate body higher than the bed surface on which the patient lies. During the operation, the patient's calves are placed on the support 1.

[0028] An opening is provided in the bracket 1, and a flushing member 2 is provided below the opening.

[0029] The flushing member 2 comprises a transparent plate 21, a flushing head 22, a water collecting head 23, a guide soft leather 24 and a wire mesh 25. The wire mesh 25 is fixed in the opening and used to support the patient's calf posterior muscles. One end of the transparent plate 21 is hinged to the inner side of the opening. A guide groove is provided on the inner side of the transparent plate 21. The flushing head 22 is detachably connected to the high end of the transparent plate 21 through a snap-on structure. One end of the flushing head 22 is connected to an external pump, and the other end is located outside the guide groove after passing through the transparent plate 21. The pump is used to introduce clean distilled water into the guide groove so that the distilled water continuously flushes the blood stains falling into the guide groove. The water collecting head 23 is fixed to the lower end of the transparent plate 21. A discharge port is provided on the water collecting head 23. The discharge port is used to discharge the distilled water and blood stain mixture flushed from the upstream to the recovery tank below. A guide soft leather 24 is fixed at the lower edge of the discharge port. The guide soft leather 24 is used to guide the water flow to fall into the recovery tank stably to reduce the probability of water splashing.

[0030] Preferably, the height of the water collecting head 23 is higher than the height of the guide groove, which can effectively prevent the mixture coming down from the upstream from passing over the water collecting head 23 and contaminating the entire operating space.

[0031] Preferably, the material of the wire mesh 25 is a soft tissue equivalent material or a low atomic number material.

[0032] An X-ray emitter 3 is arranged directly below the transparent plate 21 . The rays emitted by the ray emitting end of the X-ray emitter 3 can pass through the transparent plate 21 and the wire mesh 25 to photograph the inside of the patient's calf located above the bracket 1 .

[0033] Through the above design, when necessary, the doctor can turn on the X-ray emitter 3 to allow the rays emitted by the X-ray emitter 3 to pass through the patient's calf on the bracket 1 to photograph the positions of metal parts such as screws inside the calf. During the shooting process, the rays pass through the transparent plate 21 of the same material and then flow water. The transparent plate 21, the flow water and the wire mesh 25 that cannot be effectively captured by the X-rays can reduce the impact on the internal structure of the calf during imaging. Therefore, the above design allows the doctor to effectively identify the specific positions of metal parts such as screws inside the calf, thereby increasing the probability of successful surgery.

[0034] When using X-rays, use the lowest possible radiation dose to obtain clear images; or use automatic exposure control technology to ensure that each exposure uses the lowest necessary dose.

[0035] Example 2

[0036] like Figure 3 , based on Example 1, the overall structure of the bracket 1 is optimized.

[0037] The bracket 1 includes a stretcher 11, a vertical rod 12 and a bottom plate 13. The stretcher 11 and the bottom plate 13 are connected by the vertical rod 12 for damping rotation. Damping plates are fixed on the contact surfaces of the two ends of the vertical rod 12 with the stretcher 11 and the bottom plate 13 respectively. When the user applies a certain force to the stretcher 11, the vertical rod 12 and the bottom plate 13, the vertical rod 12 can be used as a support to lift the stretcher 11 from the bottom plate 13 to form a support surface higher than the bottom plate 13, so that the patient can place the calf part on the stretcher 11.

[0038] Preferably, if it is believed that the damping plate cannot provide stable limiting, a locking bolt can be added to the rotational connection between the support plate 11, the vertical pole 12, and the vertical pole 12 and the bottom plate 13. The locking bolt passes through the vertical pole 12 and is threadedly connected to the corresponding support plate 11 or bottom plate 13 respectively. Tightening the locking bolt can greatly improve the limiting stability between the support plate 11, the vertical pole 12 and the bottom plate 13.

[0039] Preferably, a placement groove is opened on the bottom plate 13, and the vertical rod 12 is rotatably connected to the inner wall of the placement groove. When the bracket 1 is not in use, the vertical rod 12 can be rotated and placed in the placement groove to reduce the space occupied by the bracket 1.

[0040] Preferably, a plurality of anti-skid grooves are provided on the bottom surface of the bottom plate 13 , and the bottom surface of the bottom plate 13 is placed in contact with the surface of the bed on which the patient lies. The anti-skid grooves can reduce the probability of accidental movement of the bracket 1 .

[0041] Preferably, a foot support 4 is arranged at the end of the support 1, where the patient's ankle is protected.

[0042] The foot support 4 includes a tenon 41, a mortise 42, a side bar 43 and a cross bar 44. The tenon 41 is fixed to the end surface of the bracket 1. A circular groove is provided in the mortise 42 for engaging with the tenon 41 or magnetically engaging with the tenon 41. Two side bars 43 are fixed to the mortise 42, and the ends of the two side bars 43 are closed by the cross bar 44. The patient places the heel between the two side bars 43 and places the back of the sole on the cross bar 44. The foot support 4 is a stable structure for supporting the foot.

[0043] Preferably, the tenon 41 is a smooth curved surface, and the circular groove adapted therewith is also a smooth curved surface, so as to reduce the residue of bacteria and microorganisms in sanitary dead corners that are difficult to clean.
