Description

Technical Field

[0001] This utility model relates to the field of orthopedic positioning and guidance technology, specifically to a positioning and guidance device for bone and joint surgery. Background Technology

[0002] In orthopedic clinical practice, doctors use a variety of treatment methods, including drugs, surgery, and physical therapy, to maintain and develop the normal shape and function of the musculoskeletal system, while effectively dealing with various injuries and diseases. For many orthopedic patients, the treatment and recovery process often requires precise drilling into the affected bone. These drilling operations are either to precisely deliver medication into the bone to promote tissue repair and regeneration, or to drain pus to effectively control infection and prevent the condition from worsening. However, to achieve these drilling operations with accuracy, the assistance of advanced and reliable positioning and guiding devices is indispensable.

[0003] Traditional orthopedic positioning and guidance devices meet the basic needs of surgery to a certain extent, but their limitations are becoming increasingly apparent. Most of these devices rely on mechanical components to achieve positioning functions. Although they can provide guidance to a certain extent, they still have many shortcomings in terms of adjustment range and accuracy. In particular, when faced with complex and ever-changing surgical sites and angle requirements, traditional devices often lack flexibility and cannot ensure the smooth progress of surgery and the safe recovery of patients. Therefore, we propose a positioning and guidance device for bone and joint surgery. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1 to 10 This utility model provides a technical solution: a positioning and guiding device for bone and joint surgery, comprising: an operating table 1, with a guardrail 11 fixedly connected to one side of the operating table 1.

[0031] It also includes: drive component 2, which is located on one side of the operating table 1 and is used to drive the device to move;

[0032] The lifting component 3 is located in the middle of the drive component 2. The lifting component 3 is used to adjust the position and height of the device. A rotating component 4 is provided on the upper side of the lifting component 3. The rotating component 4 is used to adjust the rotation angle of the device. A telescopic component 5 is provided at the lower part of the rotating component 4. The telescopic component 5 is used to extend the length of the device. A clamping component 6 is provided on the side of the telescopic component 5 away from the rotating component 4. The clamping component 6 is used to fix surgical instruments of different sizes.

[0033] When using the device, the drive assembly 2 can be fixedly connected to the operating table 1, so that the operating table 1 and the drive assembly 2 can temporarily form a whole. Then, by running the drive assembly 2, the entire device can be moved, which makes it easy to adjust the position of the device. Then, by running the lifting assembly 3, the position and height of the device can be adjusted according to the different patients, thereby improving the practicality of the device. By setting the rotating assembly 4, the telescopic assembly 5 can be rotated and adjusted according to the patient's condition, which can drive the clamping assembly 6 to rotate and adjust, so that the surgical instruments held by the clamping assembly 6 can be positioned for the patient's disease location. The telescopic assembly 5 can extend the length of the device, thereby improving the flexibility of the device.

[0034] The drive assembly 2 includes two clamping assemblies 21. Each clamping assembly 21 includes a base block 211. A connecting plate 22 is fixedly connected to the opposing surfaces of the two base blocks 211. A threaded rod 23 is rotatably connected to the opposing surfaces of the two base blocks 211. A motor 24 is fixedly connected to the side of one base block 211 away from the other base block 211. The output shaft of the motor 24 passes through the side of the base block 211 near the motor 24 and extends to the side of the base block 211 away from the motor 24. The output shaft of the motor 24 is fixedly connected to the threaded rod 23. A support platform 25 is threadedly connected to the threaded rod 23. The support platform 25 is slidably connected to the connecting plate 22.

[0035] The bottom block 211 is symmetrically fixedly connected with sliding rods 212 at the bottom, and a double-acting screw 213 is rotatably connected to the middle of the bottom block 211. Clamping plates 214 are provided on both sides of the guardrail 11. The two sliding rods 212 are slidably connected to the clamping plates 214. The guardrail 11 is located between two adjacent clamping plates 214. The two clamping plates 214 are threadedly connected to the double-acting screw 213.

[0036] When using the device, firstly, it needs to be connected to the operating table 1. The operator rotates the bidirectional lead screw 213, which then drives the two clamping plates 214 to move towards the guardrail 11. Through the cooperation of several clamping plates 214, the clamping assembly 21 is connected to the guardrail 11, thus supporting and connecting the entire drive assembly 2. Next, the position of the device needs to be adjusted according to the patient's condition. By running the motor 24, the threaded rod 23 is rotated. Since the threaded rod 23 is threadedly connected to the support platform 25, the rotation of the threaded rod 23 can drive the support platform 25 to move, and then drive the entire device to move. Since the support platform 25 is slidably connected to the connecting plate 22, the stability of the support platform 25 is enhanced when the support platform 25 moves.

[0037] The lifting assembly 3 includes a support rod 31, the lower end of which is fixedly connected to the upper end of the support platform 25. A first connecting block 32 is fixedly connected to the lower part of the support rod 31, and a second connecting block 34 is slidably connected to the upper part of the support rod 31. An electric push rod 33 is fixedly connected to the upper end of the first connecting block 32, and the piston rod output end of the electric push rod 33 is fixedly connected to the lower end of the second connecting block 34.

[0038] The rotating component 4 includes a docking block 41 and a connecting block 43. The connecting block 43 is fixedly connected to the connecting block 34. A rotating block 44 is fixedly connected to the side of the docking block 41 near the connecting block 343. The rotating block 44 is rotatably connected to the connecting block 343. A handle 42 is fixedly connected to the side of the docking block 41 away from the connecting block 343. A locking component 45 is provided on the upper part of the connecting block 343. The locking component 45 is used to limit the position of the rotating block 44. The locking component 45 includes a rubber block 451. A rotating block 452 is rotatably connected to the upper part of the rubber block 451. A threaded bolt 453 is fixedly connected to the upper end of the rotating block 452. The threaded bolt 453 is threadedly connected to the connecting block 343.

[0039] The telescopic assembly 5 includes a second docking block 51, the upper end of which is fixedly connected to the lower part of the first docking block 41. A slider 53 is slidably connected to the inner cavity of the second docking block 51. A threaded rod 52 is rotatably connected to the middle part of the second docking block 51. The threaded rod 52 is threadedly connected to the slider 53. A main rod 54 is fixedly connected to the lower end of the slider 53. The main rod 54 is slidably connected to the lower part of the second docking block 51. A secondary rod 55 is slidably connected to the inner cavity of the main rod 54.

[0040] A locking component 56 is provided on the side of the auxiliary rod 55 near the slider 53. The locking component 56 is used to limit the position of the auxiliary rod 55 on the main rod 54. The locking component 56 includes a housing 561 and a spring 563. A locking block 562 is slidably connected to the inner cavity of the housing 561. The side of the spring 563 near the locking block 562 is fixedly connected to the locking block 562, and the side of the spring 563 away from the locking block 562 is fixedly connected to the inner wall of the housing 561. Several slots 57 that cooperate with the locking block 562 are opened on one side of the main rod 54.

[0041] After adjusting the position of the device, its height needs to be adjusted. By operating the electric push rod 33, the piston rod of the electric push rod 33 can push the connecting block 34 upward, thereby driving the rotating component 4 and the telescopic component 5 upward together. Then, the position and height of the device are determined according to the patient's condition. Next, the rotation angle of the telescopic component 5 needs to be adjusted, thereby driving the clamping component 6 to rotate at the same angle. This allows the surgical instruments held by the clamping component 6 to be positioned relative to the patient's affected area. By rotating the handle 42, the docking block is moved. The first 41 rotates, and then the first 44 rotates through the first 41 docking block. During the rotation, medical staff can judge the rotation angle of the first 41 docking block by the indicator arrow set on the first 44, thereby improving the accuracy of the device rotation process. After the device angle is adjusted, the medical staff rotates the threaded bolt 453 to drive the second 452 rotating towards the first 44 rotating block, and then pushes the first 451 rubber block to contact the surface of the first 44 rotating block, and then limits and fixes the first 44 rotating block by the first 451.

[0042] Then, medical staff need to adjust the length of the device according to the patient's condition so that the medical device held by the clamping component 6 can more easily locate the patient's lesion. First, the medical staff applies force to the clamping block 562, pushing it from the adjacent slot 57 into the outer shell 561, causing the spring 563 to retract. Then, a force is applied to the auxiliary rod 55, causing it to slide within the main rod 54. When the clamping block 562 contacts the new adjacent slot 57, the spring 563 releases its elastic force. This will cause the spring 563 to extend, and then push the locking block 562 into the inner cavity of the adjacent locking slot 57, thereby limiting the position of the auxiliary rod 55 in the inner cavity of the main rod 54. Then, medical staff can rotate the threaded rod 52. Since the threaded rod 52 is threadedly connected to the slider 53, when the threaded rod 52 rotates, it will cause the slider 53 to slide in the inner cavity of the docking block 51, and then drive the main rod 54 and the auxiliary rod 55 to move together. This allows the length of the device to be adjusted according to the patient's condition, thereby improving the flexibility of the device.

[0043] Example 2

[0044] The clamping assembly 6 includes a connecting block 4 61 and a docking block 3 62. The connecting block 4 61 is fixedly connected to the auxiliary rod 55. The connecting block 4 61 and the docking block 3 62 are connected by bolts. A bidirectional lead screw 2 63 is rotatably connected to the middle of the docking block 3 62. Clamping blocks 64 are symmetrically and slidably connected to the inner cavity of the docking block 3 62. The two clamping blocks 64 are threadedly connected to the bidirectional lead screw 2 63. Rubber blocks 2 65 are fixedly connected to the opposite surfaces of the two clamping blocks 64.

[0045] When medical staff need to replace the medical device held by the clamping assembly 6 according to the patient's condition, they place the medical device to be replaced between the two rubber blocks 65, and then rotate the two-way lead screw 63 to drive the two clamping blocks 64 to move towards the opposite side, thereby driving the two rubber blocks 65 to clamp the medical device. Since the rubber blocks 65 are made of rubber, damage to the medical device can be reduced during the clamping process. Since the connecting block 61 and the docking block 62 are connected by bolts, when it is necessary to rotate the docking block 62, the bolts and nuts are released to fix the position of the docking block 62, thereby allowing the docking block 62 to be rotated and adjusted, which further improves the flexibility of the device during use.
