Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a multi-angle fixation bracket device for orthopedic surgery. Background Technology

[0002] Orthopedic surgery is a surgical treatment for diseases of the musculoskeletal system, including bones, joints, muscles, and ligaments. It is primarily used to repair injuries, correct deformities, treat diseases, and restore function. Its applications are wide-ranging, including fracture and dislocation reduction and fixation, joint replacement, spinal surgery, bone tumor resection, and soft tissue surgeries such as ligament repair and tenosynovitis release. Surgical methods are divided into traditional open surgery and minimally invasive surgery. The former offers a clear surgical field but is more invasive, while the latter (such as arthroscopy and spinal endoscopy) is increasingly used due to its advantages of small incisions, less bleeding, and faster recovery.

[0003] During orthopedic leg surgery, the leg needs to be supported and elevated. Currently, fixation braces are mainly fixed on the operating table, and their fixed position makes it inconvenient to adjust the support angle according to the surgical incision location and the surgeon's operating habits, which increases the difficulty and time of the surgery. In view of this, we propose a multi-angle fixation brace device for orthopedic surgery. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a multi-angle fixation bracket device for orthopedic surgery to solve the current technical problem of inconvenience in adjusting the angle.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-angle fixation bracket device for orthopedic surgery, comprising: a fixation mechanism including a mounting plate, a first adjusting limiting plate being provided at the end of the mounting plate, a connecting rod being provided at the end of the first adjusting limiting plate, and a second adjusting limiting plate being provided at the end of the connecting rod, the first adjusting limiting plate and the second adjusting limiting plate being concentric arc-shaped plates, and the connecting rod being bent into an S-shape along its long axis; a support mechanism including a first sliding plate and a second sliding plate respectively slidably mounted on the first adjusting limiting plate and the second adjusting limiting plate, a connecting plate being provided between the first sliding plate and the second sliding plate, support plates being equidistantly provided at the top of the connecting plate, and a first positioning plate and a second positioning plate being symmetrically provided at the bottom of the connecting plate.

[0006] Preferably, the first adjusting limit plate and the second adjusting limit plate are respectively provided with a first sliding groove and a second sliding groove, and the first sliding plate and the second sliding plate are respectively slidably disposed in the first sliding groove and the second sliding groove.

[0007] Preferably, the height of the second sliding plate is higher than the height of the first sliding plate.

[0008] Preferably, all of the plurality of support plates are arranged in an arc shape, and the arc of the plurality of support plates gradually decreases from front to back.

[0009] Preferably, the first positioning plate and the second positioning plate are both bent several times along the long axis direction, and both the first positioning plate and the second positioning plate are bent into an m shape. The ends of the first positioning plate and the second positioning plate are respectively provided with a first ball and a second ball.

[0010] Preferably, the back of the first adjusting limiting plate is provided with a first limiting groove adapted to the size of the first ball, and the front of the second adjusting limiting plate is provided with a second limiting groove adapted to the size of the second ball.

[0011] Preferably, the mounting plate has a U-shaped portion at its beginning, and a fixing groove is formed between the mounting plate and the U-shaped portion. Threaded holes are symmetrically opened on the U-shaped portion.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of a first adjusting limiting plate and a second adjusting limiting structure, and by designing the first adjusting limiting plate and the second adjusting limiting plate as a "concentric arc structure", combined with the movement space reserved by the S-shaped connecting rod, allows the support mechanism to slide along an arc trajectory with a unified arc center as the axis. This design conforms to the rotation law of the human leg with the hip as the axis, and can flexibly adjust the leg support angle according to the surgical incision position and the doctor's operating habits, avoiding the problem of limited surgical field of vision caused by the "single position and rigid angle" of traditional fixed brackets, reducing the difficulty of surgical operation, and, together with the positioning plate and ball structure, can quickly complete the fixation of the bracket, solving the current problem of inconvenience in adjusting the angle.

[0013] 2. This utility model also designs a first positioning plate and a second positioning plate structure, with limiting grooves for matching balls respectively opened on the back of the first adjusting limiting plate and the front of the second adjusting limiting plate. Together with the ball structure at the end of the M-shaped elastic positioning plate, it realizes the automatic connection of "adjustment-limiting-fixing". During adjustment, external force pushes the support mechanism to make the ball disengage from the limiting groove. After the angle is determined, the elastic restoring force of the M-shaped positioning plate will drive the ball to automatically lock into the corresponding limiting groove, and fixation can be completed without additional tools. This design not only makes angle adjustment more labor-saving, but also achieves "graded fixation" through the spacing of the limiting grooves, ensuring accurate and stable support angle and avoiding the risk of leg displacement caused by the slippage of the support during surgery.

[0014] 3. This utility model also designs a connecting plate and a support plate structure. The top of the connecting plate of the support mechanism is equidistantly provided with an arc-shaped support plate that gradually decreases in size from front to back. The arc-shaped structure can fit closely with the contour of the leg, disperse the pressure on the leg, and avoid poor blood circulation caused by local compression. The gradually decreasing size design is adapted to the difference in thickness from the thigh to the calf, further improving the stability and comfort of the support and reducing the restlessness of the patient during surgery due to leg discomfort.

[0015] 4. The height of the second sliding plate of this utility model is higher than that of the first sliding plate, so that the connecting plate is designed with a fixed angle of "incline from front to back". This structure can keep the leg naturally raised and reduce the flow of blood to the surgical site (such as the calf and ankle) by using gravity, thereby helping to reduce the amount of bleeding from the surgical incision, providing doctors with a clearer surgical field of vision, and reducing the time cost of intraoperative hemostasis.

Detailed Implementation

[0018] like Figures 1 to 5As shown, this utility model relates to a multi-angle fixation bracket device for orthopedic surgery, including a fixation mechanism 100 and a support mechanism 200 slidably disposed on the fixation mechanism 100. The fixation mechanism 100 includes a mounting plate 101, a first adjusting limit plate 102 is disposed at the end of the mounting plate 101, a connecting rod 103 is disposed at the end of the first adjusting limit plate 102, and a second adjusting limit plate 104 is disposed at the end of the connecting rod 103. The support mechanism 200 includes a first sliding plate 202 and a second sliding plate 201 respectively slidably mounted on the first adjusting limit plate 102 and the second adjusting limit plate 104. A connecting plate 203 is disposed between the first sliding plate 202 and the second sliding plate 201. The connecting plate 203 is inclined upward from front to back. Support plates 204 are equidistantly disposed at the top of the connecting plate 203. The support plates 204 are arc-shaped and gradually decrease in size from front to back. A first positioning plate 205 and a second positioning plate 206 are symmetrically disposed at the bottom of the connecting plate 203. This utility model allows for flexible adjustment of the support angle according to the surgical incision location and the doctor's operating habits, reducing the difficulty of surgery and shortening the time. The arc-shaped support plate of 204 conforms to the leg to distribute pressure, and the gradually changing size adapts to the leg shape, improving support stability and comfort. The M-shaped positioning plate is equipped with ball bearings and limiting grooves, which can automatically fix the position in stages without tools, avoiding displacement during surgery.

[0019] Specifically, the mounting plate 101 has a U-shaped portion 1011 at its beginning, and a fixing groove is formed between the mounting plate 101 and the U-shaped portion 1011. Threaded holes are symmetrically provided on the U-shaped portion 1011. The fixing groove allows for easy connection of the mounting plate 101 to the side of the operating table, while the threaded holes facilitate the use of bolts or other fasteners to securely fix the device to the operating table, preventing the device from shaking during surgery and ensuring the smooth progress of the operation.

[0020] Furthermore, both the first adjusting limit plate 102 and the second adjusting limit plate 104 are arc-shaped along their long axis, with the arc centers of the first adjusting limit plate 102 and the second adjusting limit plate 104 coinciding. The connecting rod 103 is bent into an S-shape along its long axis. The arc-shaped limit plates provide an arc trajectory for the sliding adjustment of the support mechanism 200. The consistent arc centers ensure the stability and accuracy of the support mechanism 200 when adjusting its sliding angle. The arc-shaped motion trajectory can also adapt to the rotation of the human leg around the hip axis. The S-shaped connecting rod 103, while connecting the two limit plates, provides space for the first positioning plate 205 and the second positioning plate 206 to move, preventing component collisions.

[0021] It is worth noting that the first adjusting limiting plate 102 and the second adjusting limiting plate 104 are respectively provided with a first sliding groove 1021 and a second sliding groove 1041, and the first sliding plate 202 and the second sliding plate 201 are respectively slidably disposed in the first sliding groove 1021 and the second sliding groove 1041. The cooperation structure of the sliding groove and the sliding plate provides guidance for the sliding of the support mechanism 200 on the fixed mechanism 100, ensuring that the sliding process is smooth and will not deviate, thereby accurately adjusting the angle of the support mechanism 200 to suit the surgeon's surgical needs.

[0022] It is worth mentioning that the first positioning plate 205 and the second positioning plate 206 are both bent several times along their long axis, forming an "m" shape. The ends of the first positioning plate 205 and the second positioning plate 206 are respectively equipped with a first ball bearing 207 and a second ball bearing 208. The "m"-shaped bending structure gives the positioning plates a certain degree of elasticity, allowing them to better fit with the limiting plate. The ball bearings convert the sliding friction between the positioning plate and the limiting plate into rolling friction. When the ball bearings are within the limiting groove, they can limit the support mechanism 200. When an external force is applied, the first positioning plate 205 and the second positioning plate 206 will bend and deform again, causing the ball bearings to disengage from the limiting groove. Each adjustment of a certain angle can automatically fix the position, making the angle adjustment operation of the support mechanism 200 more effortless.

[0023] It is worth noting that the back of the first adjusting limiting plate 102 is provided with a first limiting groove 1022 that matches the size of the first ball bearing 207, and the front of the second adjusting limiting plate 104 is provided with a second limiting groove 1042 that matches the size of the second ball bearing 208. This matching ball bearing and limiting groove structure can limit and fix the support mechanism 200 after it has been adjusted to a suitable angle, preventing the support mechanism 200 from sliding due to external forces during surgery and ensuring the stability of the leg support position.

[0024] Working Principle: This embodiment provides a multi-angle fixation bracket device for orthopedic surgery. In use, the device is first fixed to the operating table using the mounting plate 101 in the fixation mechanism 100. Specifically, the U-shaped portion 1011 at the beginning of the mounting plate 101 and the fixing groove formed by the mounting plate 101 are engaged with the side of the operating table. Then, the device is firmly fixed to the operating table using bolts or other fasteners through the symmetrically opened threaded holes on the U-shaped portion 1011, preventing the device from shaking during surgery and providing a stable foundation for subsequent operations. Subsequently, the patient's leg is placed on the support plates 204 equidistantly positioned at the top of the connecting plate 203. Because the support plates 204 are arc-shaped and gradually decrease in size from front to back, they better conform to the curve of the leg, providing stability and... The support mechanism provides comfortable support, and the upward tilt of the connecting plate 203 from front to back allows for upward tilting of the leg, reducing blood flow to the leg during surgery and minimizing bleeding. Furthermore, the angle of the support mechanism 200 can be adjusted according to the surgical incision location and the surgeon's operating habits to meet the leg support requirements. The first sliding plate 202 and the second sliding plate 201 of the support mechanism 200 are respectively slidably positioned within the first groove 1021 of the first adjusting limit plate 102 and the second groove 1041 of the second adjusting limit plate 104 in the fixing mechanism 100. Both the first adjusting limit plate 102 and the second adjusting limit plate 104 are arc-shaped along their long axis with the same arc center. Simultaneously, the connecting rod 103 has an S-shaped bend to allow for component movement. The space is limited, so during adjustment, medical staff can apply external force to push the support mechanism 200. At this time, the support mechanism 200 will be centered on the common arc center of the first adjustment limiting plate 102 and the second adjustment limiting plate 104, driving the first sliding plate 202 and the second sliding plate 201 to slide along the arc trajectory in the first sliding groove 1021 and the second sliding groove 1041 respectively. During the sliding process, the first positioning plate 205 and the second positioning plate 206 symmetrically arranged at the bottom of the connecting plate 203 will move accordingly. Since both are M-shaped and elastic, the first ball 207 and the second ball 208 at their ends are initially engaged in the first limiting groove 1022 on the back of the first adjustment limiting plate 102 and the second limiting groove 1042 on the front of the second adjustment limiting plate 104 respectively. When an external force is applied, the first positioning plate 205 and the second positioning plate 206 will bend and deform, causing the first ball 207 to disengage from the first limiting groove 1022 and the second ball 208 to disengage from the second limiting groove 1042. This allows the support mechanism 200 to continue sliding and adjusting its angle. When the support mechanism 200 is adjusted to the angle required for the surgery, the external force is stopped. At this time, the elastic deformation of the first positioning plate 205 and the second positioning plate 206 is restored, and the first ball 207 and the second ball 208 will re-engage into the corresponding positions of the first limiting groove 1022 and the second limiting groove 1042, thereby limiting and fixing the support mechanism 200 to prevent it from sliding during subsequent surgeries. This facilitates the surgeon's operation, reduces the difficulty of the surgery, and saves surgical time.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
