Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a bone transport device. Background Art

[0002] Chronic, refractory wounds are wounds that show no signs of healing after at least one month of treatment. Currently, a comprehensive approach is often used to treat chronic, refractory wounds, particularly diabetic foot. Conventional treatments include debridement, vacuum aspiration, flap therapy, and anti-infective therapy, but these still result in high amputation rates and unsatisfactory healing rates.

[0003] Transverse tibial bone transfer (TTBMT) is a surgical treatment for diabetic foot disease based on the Ilizanov technique and the principle of tension-stress law. Through slow and continuous tibial bone distraction, it stimulates cell proliferation and biosynthesis, mobilizes the body's self-repair capabilities, improves blood flow to the foot, and promotes the healing of calf and foot ulcers. However, existing TTBMT tools are relatively large, requiring the insertion of numerous bone pins, resulting in extensive wounds and a slower recovery. Summary of the Invention

[0004] The utility model provides a bone transport device, aiming to solve the above problems.

[0005] The utility model is implemented by adopting the following technical solution: a bone transport device, characterized in that it includes a fixed plate, a lifting rod, a support plate, and a knob, the fixed plate is provided with a knob mouth, a bone pin hole, a fixing device, and a first limiting hole; the lifting rod is arranged in a flat shape, and the lifting rod is provided with an external thread; the support plate is also provided with a bone pin hole, a fixing device, and a second limiting hole; the knob is provided with a threaded hole; the knob is placed in the knob mouth; the lifting rod connects the fixed plate, the support plate and the knob through the first limiting hole, the second limiting hole and the threaded hole.

[0006] Furthermore, the fixing plate has at least two bone pin holes.

[0007] Furthermore, the fixing device includes a screw and a fixing hole; the fixing hole is arranged on the fixing plate, and the fixing hole is connected to the bone pin hole, and the two are in a vertical relationship.

[0008] Furthermore, the fixing device includes screws, fixing holes, and clamps.

[0009] Furthermore, the lifting rod is flat in the middle and has external threads on both sides.

[0010] Furthermore, the knob is provided in a disc shape, a threaded hole is provided in the middle of the knob, and stripes are provided on the outside of the knob.

[0011] Furthermore, one end of the screw is provided with a hexagon socket head.

[0012] Furthermore, the second limiting hole does not penetrate the supporting sheet.

[0013] The beneficial effects of the utility model are:

[0014] This device minimizes surgical incisions, allowing two bone needles to be inserted into a single wound, significantly reducing the number of wounds caused by the insertion of bone needles. It also boasts high bone transfer speeds, requiring only the rotation of a knob to achieve bone transfer, reducing the time required by conventional bone transfer devices by at least half. It also boasts high stability and ease of operation. Compared to conventional bone transfer devices, this device utilizes fewer parts, is more convenient to assemble, and reduces surgical time. Its ease of operation makes it easier for junior physicians to learn and easier for lower-level hospitals to implement, thus enabling more effective promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following examples further illustrate the present invention, but are not intended to limit the present invention. Specific experimental conditions and methods not specified in the following examples are conventional methods well known to those skilled in the art.

[0023] Example 1;

[0024] like Figure 1-5A bone transport device, characterized in that it includes a fixed plate 1, a lifting rod 2, a support plate 3, and a knob 4. The fixed plate is provided with a knob opening 11, a bone pin hole 12, a fixing device, and a first limiting hole 14; the knob opening 11 is provided in the middle position of the fixed plate 1, mainly for placing the knob 4; there are at least two bone pin holes 12, which can be provided according to actual needs; the main function of the bone pin hole 12 is to allow the bone pin 6 (i.e., Kirschner wire) to pass through for surgical operations. The fixing device includes a fixing hole 13 and a screw 5; the number of the fixing holes 13 is the same as the number of the bone pin holes 12; the fixing holes 13 and the bone pin holes 12 are connected and in a vertical relationship. The fixing hole 13 is provided with an internal thread, and the screw 5 is screwed into the fixing hole 13 through the thread, thereby fixing the bone pin 6 in the fixing hole and the fixed plate 1. The support plate 3 is also provided with a bone pin hole, a fixing hole, and a second limiting hole 31. The second limiting hole 31 does not penetrate the support plate 3. When the lifting rod 2 rotates to the bottom of the second limiting hole, the lifting rod 2 and the support plate 3 are fixed. The screw 5 can be fixed to the support plate 3 through the fixing hole 13.

[0025] The first limiting hole 14 is square in the middle and has arc-shaped ends, which are engaged with the lifting rod 2; the lifting rod 2 is flat in shape and is provided with an external thread; a threaded hole 41 is provided in the middle of the knob 4; the lifting rod 2 connects the fixed plate 1, the support plate 3 and the knob 4 through the first limiting hole 14, the second limiting hole 31 and the threaded hole 41, and the fixed plate 1 is limited and cannot rotate around the lifting rod as the axis; the lifting rod 2 is rotated to the bottom of the second limiting hole to fix the support plate, and can no longer rotate around the lifting rod as the axis; the knob 4 can be rotated around the lifting rod as the axis, and the lifting and lowering movement of the lifting rod 2 is achieved by rotating the knob 4.

[0026] In order to better fix the bone needle, the fixing plate and the supporting plate, one end of the screw is set in an inner hexagonal shape, which is quick to operate and will not slip.

[0027] In order to facilitate operation when turning the knob, the knob is circular with a threaded hole in the middle. In order to increase the friction on the outside of the knob, stripes are also provided on the outside of the knob.

[0028] Working principle:

[0029] When performing a bone transfer operation, the bone transfer device structure is first assembled, and then a point is determined on the external bone part where the surgery needs to be transferred, and a bone needle is inserted. The bone transfer device is put on the bone needle, and the bone transfer device is fixed to the bone needle with a screw. It is reinforced with an Allen wrench tool, and the knob is rotated to raise the lifting rod, driving the support plate to rise. The bone needle on the support plate drives the cut bone to realize the bone transfer activity.

[0030] Example 2:

[0031] The difference between Example 2 and Example 1 lies in the difference in the fixing device; the fixing plate and the support plate of Example 2 do not need to be provided with bone needle holes. The fixing device of Example 2 includes a screw 5, a fixing hole 13, and a splint 7; the fixing hole 13 and the bone needle hole are not connected, and the splint has a hole for the screw to pass through; when the bone needle 6 is fixed, the bone needle is placed between the splint 7 and the fixing plate 1, and then the splint 7 is fastened to the fixing plate 1 using the screw 5, and the bone needle clamped between the fixing plate 1 and the splint 7 is thereby fixed. In order to prevent the bone needle from swinging due to external force during operation, a limiting groove is provided on the splint, which effectively limits the space in which the bone needle can move.

[0032] The above is only one specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, and any changes or simple replacements that are not conceived through creative work should be included in the scope of protection of the present invention.
