Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable-angle elbow joint surgical positioning support. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators that are used directly or indirectly on the human body. In elbow surgery, the fixation of the patient's elbow position and the adjustment of the angle are crucial for the smooth progress of the operation. Therefore, an adjustable elbow joint surgical positioning support is required.

[0003] Traditional positioning supports have a fixed shape, making it impossible to fit the patient's elbow shape properly, resulting in low patient comfort and affecting the exposure of the surgical site. The support columns are generally of a fixed height, making it difficult to adapt to different operating table heights and the surgeon's operational needs. The adjustment method of the fixation straps is also relatively simple and crude, with unstable fixation effect. With the continuous development of medical technology, existing elbow joint surgical positioning supports have been structurally improved. They are usually composed of a base, a height-adjustable support column, a rotatable support plate connection structure, and a fixation device mechanism. However, during surgery, surgeons need to frequently adjust the angle of the patient's elbow to obtain the best surgical field of vision and operating space. But existing positioning supports often require multiple steps, such as loosening multiple fixing screws, manually adjusting the angle, and then retightening the screws. This not only wastes valuable surgical time but may also increase surgical risks and patient pain. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable-angle elbow joint surgical positioning support, which aims to improve the existing positioning support in the prior art, which often requires multiple steps, such as loosening multiple fixing screws, manually adjusting the angle, and then tightening the screws again. This not only wastes valuable surgical time, but may also increase surgical risks and patient suffering.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable-angle elbow joint surgical positioning support, comprising a support plate one, a support plate two rotatably connected to the left side of the outer wall of the support plate one, a toothed disc fixedly connected to the inner wall of the support plate two, the top of the toothed disc rotatably connected to the support plate one, a fixing plate fixedly connected to the bottom left side of the support plate one, multiple springs fixedly connected to the top of the outer wall of the fixing plate, internal toothed rings fixedly connected to the top of the multiple springs, the internal toothed rings engaging with the toothed disc, and support rings rotatably connected to the top left and right sides of both the support plate one and the support plate two, and multiple support rings...

Detailed Implementation

[0017] 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.

[0018] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an adjustable elbow joint surgical positioning support, comprising a support plate 1, a support plate 3 rotatably connected to the left side of the outer wall of the support plate 1, the support plate 3 cooperating with the support plate 1 to achieve angle adjustment, a toothed disc 4 fixedly connected to the inner wall of the support plate 3, the toothed disc 4 cooperating with an inner toothed ring 7 to achieve angle fixation and adjustment, the top of the toothed disc 4 rotatably connected to the support plate 1, and a fixing plate 5 fixedly connected to the bottom left side of the support plate 1, the fixing plate 5 supporting and fixing a spring 6, and multiple... Multiple springs 6 provide elastic force to engage the internal toothed ring 7 with the toothed disc 4. The top of each spring 6 is fixedly connected to the internal toothed ring 7, which engages with the toothed disc 4 to fix the angle of the second support plate 3. Support rings 8 are rotatably connected to the top left and right sides of both the first support plate 1 and the second support plate 3. These support rings 8 support the patient's elbow. Adjustable straps 9 are fixedly connected to the front and rear sides of the outer walls of the multiple support rings 8. A locking head 10 is fixedly connected to the bottom end of the front adjustable straps 9, and a buckle 11 is fixedly connected to the bottom end of the rear adjustable straps 9. Each locking head 10 is connected to a corresponding... The buckles 11 engage with each other to secure the elbow according to its thickness. Each of the multiple support rings 8 has a protective pad 12 at its top, which engages with the corresponding support ring 8. The protective pads 12 increase the comfort of the patient's elbow. An adjusting rod 13 is fixedly connected to the bottom right side of the support plate 1. The adjusting rod 13 is used to adjust the height. A hollow sleeve 14 is slidably connected to the bottom of the outer wall of the adjusting rod 13, providing a sliding track for the adjusting rod 13. A base 15 is fixedly connected to the bottom of the hollow sleeve 14, used for lifting. For stable support, the inner wall of the hollow sleeve 14 is provided with an adjustment mechanism 2, which is used to adjust the height of the adjustment rod 13. A rotating ring 16 is connected to the middle of the outer wall of the hollow sleeve 14. The rotating ring 16 is used to drive the storage box 17 to rotate. The storage box 17 is fixedly connected to the left side of the outer wall of the rotating ring 16. The storage box 17 is used to place surgical related items. A storage slot 18 is opened on the front side of the outer wall of the storage box 17. The storage slot 18 is used to accommodate the storage box 19. The storage box 19 is slidably connected to the inner wall of the storage slot 18. The storage box 19 is used to store surgical supplies. Specifically, during angle adjustment, the operator presses down on the internal gear ring 7, compressing the spring 6 to disengage the internal gear ring 7 from the gear disc 4. At this point, the second support plate 3 is no longer restricted and can rotate freely relative to the first support plate 1, thus achieving angle adjustment. Once the appropriate angle is reached, the pressure on the internal gear ring 7 is released, the spring 6 rebounds, and pushes the internal gear ring 7 back into engagement with the gear disc 4, thereby fixing the angle of the second support plate 3. During surgery, the patient's elbow is placed on the first support plate 1 and the second support plate 3. The support ring 8 is used to support the elbow. By engaging the latch 10 at the bottom of the front adjusting belt 9 with the buckle 11 at the bottom of the rear adjusting belt 9, the adjustment and fixation can be made according to the thickness of the patient's elbow. The protective pad 12 on the top of the support ring 8 can improve the patient's comfort. When the height of the positioning support needs to be adjusted, the adjusting mechanism 2 on the inner wall of the hollow sleeve 14 is used to operate the adjusting rod 13, so that the adjusting rod 13 slides up and down inside the hollow sleeve 14, thereby changing the height of the entire positioning support. When the desired height is reached, the rotating ring 16 can rotate around the hollow sleeve 14. When the rotating ring 16 rotates, the storage box 17 fixedly connected to it also rotates, making it convenient to use the storage box 17 from different angles. The storage slot 18 opened on the front side of the outer wall of the storage box 17 is used to accommodate the storage box 19. The storage box 19 can slide in the storage slot 18, making it easy to pull out or push back the storage box 19. During the operation, some commonly used small surgical instruments or items can be placed in the storage box 19 for easy access by medical staff.

[0019] Reference Figure 1 and Figure 4 The adjusting mechanism 2 includes multiple arc-shaped plates 201, which cooperate with the limiting plate 204 to achieve different height adjustments. The multiple arc-shaped plates 201 are equidistantly fixedly connected to the left side of the outer wall of the adjusting rod 13. A reserved groove 202 is provided on the left side of the inner wall of the hollow sleeve 14. The shape of the reserved groove 202 is the same as that of the arc-shaped plates 201. All the arc-shaped plates 201 are slidably connected to the reserved groove 202. A rotating groove 203 is provided on the right side of the outer wall of the hollow sleeve 14 to provide rotation space for other components. The inner wall of the rotating groove 203 is rotatably connected to the limiting plate 204. Under normal conditions, the limiting plate 204 does not contact the arc plate 201. After the angle of the adjusting rod 13 is adjusted, the limiting plate 204 is rotated so that the limiting plate 204 is locked between the two arc plates 201, locking the adjusting rod 13 and preventing the adjusting rod 13 from moving up and down. A notch 205 is provided on the left side of the outer wall of the limiting plate 204. Under normal conditions, the notch 205 corresponds to the arc plate 201, so that the arc plate 201 on the adjusting rod 13 can slide up and down smoothly. A lever 206 is fixedly connected to the right side of the outer wall of the limiting plate 204. The lever 206 facilitates the rotation of the limiting plate 204. Specifically, in the initial state, the notch 205 of the limiting plate 204 corresponds to the arc plate 201. At this time, the adjusting rod 13 can slide freely up and down in the hollow sleeve 14. When it is necessary to adjust the height of the body position support, the adjusting rod 13 is moved up and down, and the arc plate 201 on the adjusting rod 13 slides along the reserved groove 202. When the adjusting rod 13 moves to the required height, the limiting plate 204 is driven to rotate in the rotating groove 203 by moving the lever 206. After the limiting plate 204 rotates, the notch 205 no longer corresponds to the arc plate 201, but its plate body is stuck between the two arc plates 201, thereby preventing the adjusting rod 13 from continuing to move up and down, realizing the locking and fixing of the adjusting rod 13, and ensuring that the body position support is maintained at the adjusted height.

[0020] Reference Figure 1 , Figure 2 and Figure 5 A handle 20 is fixedly connected to the front side of the outer wall of the storage box 19. The handle 20 is used to facilitate medical staff to pull out or push the storage box 19. The surface of the handle 20 is treated with anti-slip treatment to increase friction and prevent the hand from slipping during operation. A plastic tube 21 is fixedly connected to the right side of the front end of the outer wall of the tray 1. The plastic tube 21 is used to support and fix the shadowless lamp 22, and the position and angle of the shadowless lamp 22 can be adjusted as needed. The top of the plastic tube 21 is fixedly connected to the shadowless lamp 22, which is used to provide sufficient and uniform lighting for the surgical site. Specifically, the handle 20 is treated with an anti-slip coating to make it easier for medical staff to grip and apply force, thus making it easier to pull the storage box 19 out of the storage slot 18 to store or retrieve items. The plastic tube 21 has the characteristic of being flexible and shapeable. The shadowless lamp 22 is connected through the plastic tube 21. Medical staff can flexibly bend the plastic tube 21 to adjust the illumination angle and position of the shadowless lamp 22 according to the needs of surgical lighting, so as to provide better lighting conditions for surgery.

[0021] Reference Figure 1 , Figure 2 and Figure 4 An information plate 23 is provided on the bottom front side of the hollow sleeve 14. The information plate 23 is used to record relevant information of the surgical positioning support. Multiple screws 24 are threaded around the outer wall of the information plate 23. The screws 24 are used to firmly fix the information plate 23 to the hollow sleeve 14. The information plate 23 is threaded to the hollow sleeve 14 through the screws 24. A shock-absorbing pad 25 is fixedly connected to the bottom of the base 15. The shock-absorbing pad 25 is used to reduce the vibration generated by the surgical positioning support during use. The surface of the shock-absorbing pad 25 is treated with anti-slip treatment to increase the friction with the contact surface and prevent the surgical positioning support from sliding. Specifically, the information plate 23 is threadedly connected to the hollow sleeve 14 by multiple screws 24. The information plate 23 can be used to record relevant information of the surgical positioning support. The connection method of the screws 24 ensures that the information plate 23 is firmly installed and not easy to fall off, making it convenient for users to view relevant information at any time. The shock-absorbing pad 25 can play a shock-absorbing role during use, reducing the impact of vibration caused by equipment operation or external factors on the stability of the surgical positioning support. The surface of the shock-absorbing pad 25, which has been treated with anti-slip treatment, can increase the friction between the pad and the placement surface, preventing the surgical positioning support from sliding during use and improving its overall stability and safety.

[0022] Working principle: Before using the device, the operator applies downward pressure to the internal gear ring 7 located between tray 1 and tray 3. This pressure compresses the spring 6 connected to it, thereby changing the position of the internal gear ring 7 and disengaging it from the gear plate 4. At this time, tray 3 is no longer restricted by the internal gear ring 7 and can rotate freely relative to tray 1. After the operator rotates tray 3 to a suitable angle according to actual needs, they release the pressure on the internal gear ring 7. The compressed spring 6 rebounds, and the resulting elastic force pushes the internal gear ring 7 upward, re-engaging it with the gear plate 4. This fixes tray 2 3 in place. After adjustment, when the patient is undergoing surgery, the elbow is placed on support plate 1 and support plate 3. The support rings 8 located on the top left and right sides support the elbow. The adjustment bands 9 on the front and back sides of the outer wall of the support ring 8 are fixed by engaging the front buckle 10 and the rear buckle 11. During the fixation process, the engagement position can be flexibly adjusted according to the thickness of the patient's elbow, so that the elbow is stably fixed. In addition, the protective pad 12 set on the top of the support ring 8 is soft in texture, which can reduce the pressure of the support ring 8 on the elbow, increase the comfort of contact, reduce the patient's discomfort during the operation, and make it more conducive to the smooth progress of the operation. Furthermore, the notch 205 of the limiting plate 204 corresponds to the arc plate 201. At this time, the adjusting rod 13 can slide freely up and down within the hollow sleeve 14. When it is necessary to adjust the height of the body position support, the adjusting rod 13 is moved up and down, and the arc plate 201 on the adjusting rod 13 slides along the reserved groove 202. When the adjusting rod 13 moves to the required height, the limiting plate 204 is rotated in the rotating groove 203 by moving the lever 206. After the limiting plate 204 rotates, the notch 205 no longer corresponds to the arc plate 201, but its plate body is stuck between the two arc plates 201, thereby preventing the adjusting rod 13 from continuing to move up and down, realizing the locking and fixing of the adjusting rod 13, and ensuring that the body position support is maintained at the adjusted height.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
