Description

Technical Field

[0001] The utility model relates to the technical field of bone implants, in particular to a bone implant placement limiting tooling structure. Background Technique

[0002] A bone implant is to implant an artificial synthetic bone into the necrotic area, thereby providing a bone support effect for the patient. During a bone implant operation, a limiting tooling is first required to perform limb limiting work on the surgical part to avoid displacement problems during or after the operation.

[0003] The limiting toolings used for various parts of the body involved in bone implants are different. After a bone implant operation on the leg (cutting off the necrotic leg bone and replacing it with an implant, only the necrotic part is removed, not the entire leg is truncated), existing large-scale limiting toolings generally use several metal rods to penetrate the patient's leg for limiting work, and small-scale limiting devices generally use cloth straps to tie wooden boards for limiting work. This form of limiting will damage the patient's leg on the one hand and cannot be adjusted by itself, so the patient will feel uncomfortable during the postoperative recovery stage. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bone implant placement limiting tooling structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A bone implant placement limiting tooling structure includes a support plate, an adjustment component, and a limiting component. A connecting plate is installed in the middle of the two support plates. A number of limiting belts are arranged above the support plate. The limiting component is arranged inside the support plate and is used to limit or disassemble the limiting belts. A twisting block is installed at the front end of the support plate. A toothed belt is fixedly connected below the limiting belt. A disassembly block is installed on the outer wall of the support plate;

[0007] The adjustment component includes a support bottom plate, a lead screw, a moving block, and a connecting rod. A lead screw is installed in the middle of the support bottom plate. The moving block is threadedly connected to the outer wall of the lead screw. The moving block is rotatably connected to the connecting rod above. The other end of the connecting rod is rotatably connected to the bottom end of the support plate.

[0008] Further, the limiting component includes a limiting block, a return spring, a sliding groove, and a pulling rope. For the limiting block, a return spring is arranged at the rear of the limiting block. The rear end of the return spring abuts against the inner wall of the support plate. Sliding grooves are arranged on both sides of the limiting block. A pulling rope is connected to the outer wall of the limiting block.

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figures 1-4As shown in the figure, the present utility model provides a bone implant placement limiting tooling structure, which specifically includes a support plate 1, an adjustment component 3 and a limiting component 7. A connecting plate 6 is installed in the middle of the two support plates 1. The connecting plate 6 can be used to connect the two support plates 1. A plurality of limiting belts 2 are arranged above the support plate 1. The limiting component 7 is installed inside the support plate 1 and is used to limit or disassemble the limiting belt 2. A twisting block 4 is installed at the front end of the support plate 1. A toothed belt 8 is fixedly connected below the limiting belt 2. A disassembly block 5 is installed on the outer wall of the support plate 1. The present utility model is more suitable for the limiting work of bone implants in the leg. It uses the limiting belt 2 and the support plate 1 to limit the surgical part of the patient. The limiting belt 2 is not only very convenient to use, but also will not cause damage to the leg. Secondly, the adjustment component 3 can assist in adjusting the leg after the operation, so that the patient does not need to maintain a single position for a long time, which helps blood circulation and reduces the recovery time;

[0023] As Figures 2-3 shown in the figure, the adjustment component 3 includes a support bottom plate 301, a lead screw 302, a moving block 303 and a connecting rod 304. The lead screw 302 is installed in the middle of the support bottom plate 301. The moving block 303 is threadedly connected to the outer wall of the lead screw 302. The connecting rod 304 is rotatably connected above the moving block 303. The other end of the connecting rod 304 is rotatably connected to the bottom end of the support plate 1;

[0024] The specific implementation is as follows:

[0025] If it is necessary to adjust the use angle of the support plate 1, the twisting block 4 can be manually rotated. The twisting block 4 drives the lead screw 302 to rotate. The moving block 303 on the outer wall of the lead screw 302 will change the position of the bottom end of the connecting rod 304, and then change the angle between the support bottom plate 301 and the support plate 1, making the leg more comfortable.

[0026] As Figure 4 shown in the figure, the limiting component 7 includes a limiting block 701, a return spring 702, a sliding groove 703 and a pulling rope 704. The limiting block 701 is provided with a return spring 702 at the rear side. The rear end of the return spring 702 abuts against the inner wall of the support plate 1. Sliding grooves 703 are provided on both sides of the limiting block 701. A pulling rope 704 is connected to the outer wall of the limiting block 701;

[0027] The specific implementation is as follows:

[0028] Insert the limiting belt 2 into the groove body of the support plate 1. At this time, the limiting block 701 can limit the toothed belt 8 of the limiting belt 2 due to the return spring 702 on one side. If it is necessary to disassemble the toothed belt 8, the disassembly block 5 can be manually pushed upward. The disassembly block 5 makes the limiting block 701 move to one side in the middle of the sliding groove 703 through the pulling rope 704, squeezing the return spring 702, and then the limiting belt 2 can be detached.

[0029] As an implementation manner, the twisting block 4 is fixedly connected to the lead screw 302, and the rotation of the twisting block 4 can drive the rotation of the lead screw 302.

[0030] As an implementation manner, the disassembly block 5 is rotatably connected to the support plate 1, the bottom end of the pulling rope 704 is fixedly connected to the disassembly block 5, and after the disassembly block 5 is toggled, the pulling rope 704 can pull the limiting block 701 at the top end, so that the limiting block 701 is disengaged from the engaging teeth portion of the toothed belt 8.

[0031] As an implementation manner, four limiting belts 2 are provided, and the limiting belts 2 are all disassembled through the disassembly block 5.

[0032] As an implementation manner, the support plate 1 is rotatably connected to the support bottom plate 301, and the support plate 1 can change the angle with the support bottom plate 301, thereby increasing comfort.

[0033] Working principle:

[0034] When the bone implant placement limiting tooling structure is in use, first, after the patient's leg has completed bone implantation surgery, the entire support plate 1 is placed at the designated position under the leg, and then the limiting belt 2 is inserted into the groove body of the support plate 1. At this time, due to the reset spring 702 on one side, the limiting block 701 can limit the toothed belt 8 of the limiting belt 2. If it is necessary to disassemble the toothed belt 8, the disassembly block 5 can be manually toggled upward. The disassembly block 5 moves the limiting block 701 to one side in the middle of the sliding groove 703 through the pulling rope 704, compressing the reset spring 702, and then the limiting belt 2 can be disengaged. If it is necessary to adjust the use angle of the support plate 1, the twisting block 4 can be manually rotated. The twisting block 4 drives the lead screw 302 to rotate, and the moving block 303 on the outer wall of the lead screw 302 will change the position of the bottom end of the connecting rod 304, thereby changing the angle between the support bottom plate 301 and the support plate 1, making the leg more comfortable.
