Description

Technical Field

[0001] The utility model relates to the technical field of osteotomy tools, in particular to an osteotomy positioner special for tibial transverse bone transport. Background Art

[0002] In modern medical surgery, transverse tibial transfer (TTT) is an important treatment for severe diabetic foot. However, this type of surgery faces many challenges in its implementation. Traditional surgical methods mainly rely on the doctor's experience and skills, using a common three-hole osteotomy with an inner diameter of 0.25 cm. This method is not only complicated to operate, but also takes a long time to operate, and requires extremely high technical skills from the doctor.

[0003] Specifically, the traditional osteotomy method requires the doctor to repeatedly rotate and adjust the osteotome during the operation, and at the same time remember how many holes have been drilled, which is extremely cumbersome and prone to errors during the operation. In addition, since the osteotome needs to be fixed to the tibia with a Kirschner wire every time the osteotome is rotated, this not only increases the complexity of the operation, but also prolongs the anesthesia and operation time, and increases the anesthesia and operation risks for the patient.

[0004] More importantly, during the traditional osteotomy method, if the assistant and the surgeon do not cooperate well, or if the surgeon makes a deviation when rotating the osteotomy device, it may lead to uneven sizes of osteotomy bones. In severe cases, it may even increase the risk of tibial fractures during and after the operation due to excessive deviation in the rotation angle. Utility Model Content

[0005] The purpose of the utility model is to provide a special osteotomy positioner for tibial transverse bone transport to solve the problem that the traditional osteotomy method proposed in the above-mentioned background technology requires the doctor to repeatedly rotate and adjust the osteotomy during the operation, and at the same time remember how many holes have been drilled, which is extremely cumbersome and prone to errors during the operation.

[0006] To achieve the above-mentioned purpose, the utility model provides a special osteotomy locator for lateral tibial bone transport, including a rectangular plate, the surface of which is provided with at least one first incision guide line and a second incision guide line, and a direction marking circle, the rectangular plate is provided with at least two screw holes for guiding the insertion of traction screws, the rectangular plate is also provided with at least 71 osteotomy holes, and the four corners of the rectangular plate serve as positioning rod sockets.

[0007] Preferably, the rectangular plate is made of steel and has a thickness of 1-2 mm.

[0008] Preferably, the length of the first incision guide line is 16 mm, and the length of the second incision guide line is 18 mm.

[0009] Preferably, the inner diameter of the direction marking circle is 0.25 cm.

[0010] Preferably, the screw holes are located 1 cm from the inner edges of the two osteotomy holes along the first incision guiding line and the second incision guiding line, and the inner diameter of the screw holes is 5 mm.

[0011] Preferably, the inner diameter of the osteotomy hole is 0.25 cm.

[0012] Preferably, the diameter of the jacking hole is 0.25 cm for the osteotomy hole. The positioning rod is a bent rod-shaped structure, and its diameter is adapted to the diameter of the jacking hole. The rectangular area formed by the osteotomy holes is 50 mm in length and 15 mm in width.

[0013] Preferably, the osteotomy holes are located 0.5 cm from the edge of the rectangular plate and form a rectangular structure in a circle.

[0014] Preferably, a row of inner holes with an inner diameter of 0.25 cm is provided at the inner side position of the rectangular plate close to the osteotomy holes.

[0015] Preferably, the widths of the first incision guiding line and the second incision guiding line are 3 mm, and the spacing between adjacent osteotomy holes is 0.12 mm.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] In this special osteotomy locator for tibial transverse bone transport, through the incision guiding lines on the locator, doctors can accurately mark the surgical scope and incision lines, which greatly improves the accuracy and efficiency of the surgery. Secondly, the design of the screw holes on the locator makes the placement of traction screws more accurate and convenient, further simplifying the surgical steps.

[0018] More importantly, the design of the osteotomy holes on the locator enables doctors to perform pre-osteotomy operations quickly and accurately. This not only greatly reduces the surgical operation time but also lowers the surgical difficulty, making the surgical process smoother.

[0019] In addition, this locator also takes into account the bone conditions of different patients. For patients with thinner tibias, doctors can drill holes according to the inner holes below the locator to cut out bone blocks of appropriate sizes. This design reflects the flexibility and practicality of the locator.

[0020] Generally speaking, this special osteotomy locator for tibial transverse bone transport significantly improves the efficiency and success rate of tibial transverse bone transport surgery through its precise design and practical functions, bringing better treatment effects to patients.

[0026] 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a special osteotomy locator for tibial transverse bone transport, as Figures 1 - 3 shown, including a rectangular plate 1. The surface of the rectangular plate 1 is provided with at least one first incision guiding line 11 and one second incision guiding line 12 for marking the surgical scope and incision line, and a direction marking circle 17 for correctly placing the direction of the rectangular plate. The inner diameter of the direction marking circle 17 is 0.25 cm. The rectangular plate 1 is provided with at least two screw holes 13 for guiding the insertion of the traction screw 2. The rectangular plate 1 is further provided with at least 71 osteotomy holes 14 for guiding the electric drill to perform pre-osteotomy operations. The four corners of the rectangular plate 1 serve as positioning rod insertion holes 15, and the locator can be fixed on the tibia by inserting the positioning rod 3. The rectangular plate 1 serves as the basic structure of the entire locator, providing a stable and reliable support platform. The first incision guiding line 11 and the second incision guiding line 12 provided on its surface enable doctors to clearly mark the surgical scope and incision line before the operation, which greatly improves the accuracy and predictability of the operation.

[0028] Secondly, the screw holes 13 provided on the rectangular plate 1 provide guidance for the accurate insertion of the traction screw 2. This not only simplifies the surgical steps but also ensures that the traction screw can be accurately placed in the predetermined position, thereby improving the surgical effect and safety.

[0029] Furthermore, by providing at least 71 osteotomy holes 14 on the rectangular plate 1, doctors can quickly guide the electric drill for pre-osteotomy operations based on these hole positions. This design not only improves the accuracy and efficiency of osteotomy but also reduces the errors and risks that may occur during the operation.

[0030] Finally, the jacks 15 provided at the four corners of the rectangular plate 1 allow the positioner to be firmly fixed to the tibia by inserting the positioning rod 3. This design ensures the stability and reliability of the positioner during the operation, thus further enhancing the success rate of the operation and the safety of the patient.

[0031] In this embodiment, the rectangular plate 1 is made of steel material with a thickness of 1 - 2 mm, ensuring a certain strength and not being easily bent.

[0032] Specifically, the length of the first incision guide line 11 is 16 mm, and the length of the second incision guide line 12 is 18 mm. These two incision guide lines with specific lengths provide doctors with clear references for surgical incisions. The length settings of 16 mm and 18 mm are carefully calculated, and they can ensure the accuracy and appropriateness of the surgical incision, thus meeting the specific requirements of the tibial transverse bone transport operation.

[0033] Secondly, with the clear incision line lengths, doctors can more precisely plan the surgical steps and incision positions, avoiding blindness and randomness during the operation. This not only helps improve the surgical efficiency but also reduces unnecessary tissue damage, thereby reducing the patient's postoperative recovery time and the risk of complications.

[0034] Finally, this precise design also reflects the humanization and professionalism of medical devices, enhancing the convenience and safety of surgical operations. When using this positioner, doctors can perform the operation with more confidence, bringing better treatment effects to patients.

[0035] Furthermore, the screw holes 13 are located 1 cm from the inner edges of the two-sided osteotomy holes along the first incision guide line 11 and the second incision guide line 12, and the inner diameter of the screw holes 13 is 5 mm.

[0036] Furthermore, the inner diameter of the osteotomy holes 14 is 0.25 cm.

[0037] Furthermore, the inner diameter of the jack 15 is 0.25 cm for the osteotomy hole. The positioning rod 3 is a bent rod-shaped structure, and its diameter is adapted to the inner diameter of the jack 15 to ensure accurate insertion and positioning.

[0038] Furthermore, the osteotomy holes 14 are located 0.5 cm from the edge of the rectangular plate 1 and form a rectangular structure in a circle.

[0039] Further, a row of inner holes 16 is provided at a position on the surface of the rectangular plate 1 close to the inner side of the osteotomy hole 14. When the tibia is relatively thin and not sufficient to intercept a bone block of 5 cm × 1.5 cm, it can be adjusted: drill holes according to the inner holes 16 of the special osteotomy locator for tibial transverse transport (TTT) to intercept a bone block of 5 cm × 1.25 cm.

[0040] Further, the widths of the first incision guiding line 11 and the second incision guiding line 12 are 3 mm, and the spacing between adjacent osteotomy holes 14 is 0.12 mm.

[0041] Further, the length of the rectangular area formed by the osteotomy holes 14 is 50 mm and the width is 15 mm, ensuring that a tibial transverse transport bone block with a length of 50 mm and a width of 15 mm can be intercepted.

[0042] When the special osteotomy locator for tibial transverse transport of the present utility model is in use, first, the rectangular plate 1 serves as the basis of the entire locator, providing stable and reliable support. The rectangular plate 1 is made of steel material with a thickness of 1 - 2 mm, ensuring that it has a certain strength and will not be easily bent.

[0043] Surgical scope and incision line marking: The two guiding lines, the first incision guiding line 11 (with a length of 16 mm) and the second incision guiding line 12 (with a length of 18 mm), are used to clearly mark the surgical scope and incision line before the operation. Doctors can accurately plan the surgical steps and incision positions according to these two lines. Insertion of traction screws: The screw holes 13 are located 1 cm from the inner edges of the two sides of the osteotomy holes along the first incision guiding line 11 and the second incision guiding line 12, with an inner diameter of 5 mm. These holes are used to guide the accurate insertion of the traction screws 2, simplifying the surgical steps and ensuring that the traction screws can be placed at the predetermined positions. Pre-osteotomy operation: The inner diameter of the osteotomy holes 14 is 0.25 cm, and they are located 0.5 cm from the edge of the rectangular plate 1, forming a rectangular structure in a circle. These holes are used to guide the electric drill for pre-osteotomy operation, improving the accuracy and efficiency of osteotomy. Fixing of the locator: The diameter of the jack 15 is 0.25 cm, which is used in conjunction with the positioning rod 3 (a bent rod-shaped structure with a diameter adapted to the jack 15). By inserting the positioning rod 3, the locator can be firmly fixed on the tibia, ensuring stability and reliability during the operation. Adapt to different bone conditions: When the tibia is relatively thin and not sufficient to intercept a bone block of 5 cm × 1.5 cm, holes can be drilled according to these inner holes to intercept a bone block of 5 cm × 1.25 cm.

[0044] Specific usage process:

[0045] Before the operation, the doctor places the locator on the patient's skin surface, with the directional marking circle 17 placed at the proximal end, and uses a marker pen to mark the operation range according to the rectangular structure formed by enclosing a circle along the osteotomy holes 14, and marks the operation incision line according to the first incision guide line 11 and the second incision guide line 12. At the beginning of the operation, the doctor incises the skin along the incision marking line, then separates the subcutaneous tissue to expose the periosteum layer. Place the locator above the periosteum and adjust its position so that the long side is 4-5 mm away from the tibial crest. After drilling a hole with a 2.5 mm drill bit, insert the positioning rod 3 through the insertion hole 15 to fix the locator on the tibia. Use an electric drill to perform a pre-osteotomy operation according to the guidance of the osteotomy holes 14. After the pre-osteotomy is completed, use a high-frequency electrocautery to mark according to the screw holes 13, remove the locator, and drill into the traction screw with an electric drill. Finally, complete the osteotomy operation.
