Technical Field
[0001] This utility model relates to the field of orthopedic nursing technology, and in particular to an orthopedic clinical displacement stent. Background Technology
[0002] In the field of orthopedic nursing, especially in the treatment and rehabilitation of fracture patients, displacement braces play a crucial role. However, traditional orthopedic displacement braces face a series of problems that urgently need to be addressed.
[0003] When dealing with complex fractures, such as those requiring fixation at specific angles or maintaining leg stability in different patient positions, traditional displacement braces often fall short. Most lack multi-angle, omnidirectional adjustment capabilities, making it difficult to provide precise, personalized support based on individual patient needs. This severely restricts patient freedom of movement and negatively impacts rehabilitation outcomes.
[0004] Meanwhile, traditional stents are cumbersome and complicated to install and remove, which undoubtedly increases the workload of medical staff, consumes a lot of time, and reduces the overall efficiency of nursing work.
[0005] In addition, bone pins are required for fixation in some fracture treatments, but existing displacement braces cannot effectively adjust the position of the bone pins.
[0006] Therefore, in response to the above problems, we propose an orthopedic clinical displacement stent. Utility Model Content
[0007] To address the problem of inconvenient adjustment of the angle of the connecting rods used for installing bone pins in traditional orthopedic displacement stents, the purpose of this utility model is to provide a clinical orthopedic displacement stent.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: an orthopedic clinical displacement bracket, comprising two symmetrically arranged annular guide rails, several detachable position adjustment mechanisms installed on the two annular guide rails, clamping components installed on the position adjustment mechanisms, and several telescopic mechanisms installed between the two annular guide rails for adjusting the distance between the two annular guide rails.
[0009] A toothed ring is fixedly sleeved on the outer wall of the annular guide rail;
[0010] The position adjustment mechanism includes a rectangular block, with a stepped block hinged to the bottom of the rectangular block and lockable thereto. Both the bottom of the rectangular block and the top of the stepped block are provided with arc-shaped grooves that are slidably connected to the outer wall of the annular guide rail. A rotatable adjusting gear that meshes with the gear ring is installed on the rectangular block.
[0011] The telescopic mechanism includes two spheres arranged vertically and rotatably embedded in the bottom of the step block, which are used to realize the omnidirectional rotation of the spheres; a guide rod is fixedly connected to one of the spheres, and a sleeve that is slidably sleeved on the outer wall of the guide rod is fixedly connected to the other sphere.
[0012] Preferably, a first bolt is vertically and downwardly inserted through the top surface of the rectangular block, and the bottom of the first bolt is threadedly connected to the top surface of the stepped block to lock the rectangular block and the stepped block together.
[0013] Preferably, the bottom of the rectangular block and the top surface of the stepped block are respectively fixedly connected with limiting protrusions that slide with the upper and lower surfaces of the toothed ring.
[0014] Preferably, the top surface of the rectangular block is vertically downward and connected to a rotating shaft, the top of the rotating shaft is fixedly connected to a cylindrical head, and the outer wall of the rotating shaft located below the rectangular block is fixedly connected to the inner wall of the adjusting gear.
[0015] Preferably, the clamping assembly includes a lead screw threaded through the side wall of the stepped block, and one end of the lead screw located inside the annular guide rail is rotatably connected to an arc-shaped clamping block, the arc-shaped surface of which is used to clamp the patient's leg.
[0016] Preferably, a tee tube is fixedly connected to the end of the sleeve and slidably sleeved on the outer wall of the guide rod. A second bolt is threaded onto the inner wall of the side opening of the tee tube. The end of the second bolt is pressed against the outer wall of the guide rod to fix the guide rod.
[0017] Preferably, the sidewall of the stepped block is threaded with a third bolt, the end of which is pressed against the outer wall of the sphere to position the sphere.
[0018] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:
[0019] 1. The position adjustment mechanism of this orthopedic displacement bracket can move along the ring guide rail. By rotating the cylindrical head, the adjustment gear is driven to roll on the toothed ring, which can accurately adjust the position of the position adjustment mechanism on the ring guide rail. Combined with the clamping component, it can adapt to different leg sizes and fracture locations of patients, ensuring appropriate clamping force and position, effectively avoiding the impact on blood circulation due to improper fixation, and providing patients with a more comfortable and safe fixation experience.
[0020] 2. The guide rod and sleeve structure in the telescopic mechanism of this utility model can flexibly adjust the distance between the two annular guide rails to meet the differences in leg length of different patients, realize personalized support length adjustment, and further enhance the adaptability of the stent.
[0021] 3. The universal rotation design of the ball in the telescopic mechanism of this utility model allows the angle and relative position of the two annular guide rails to be freely adjusted within a certain range. It can easily cope with different patient positions or special angle fixation required for fracture sites, greatly improving the patient's freedom of movement during rehabilitation and ensuring the stability of fracture fixation, which is conducive to improving rehabilitation results.
[0022] 4. The guide rod and sleeve of this utility model can be fitted with bone pins, and the position of the bone pins can be flexibly adjusted with the help of the position adjustment mechanism. This can meet the precise requirements of bone pin position for different fracture sites and treatment stages, providing a more precise auxiliary fixation method for fracture treatment and helping to improve the effectiveness and pertinence of treatment.
[0023] 5. In the position adjustment mechanism of this utility model, the rectangular block and the stepped block are locked together by the first bolt, and each of them is provided with a limiting protrusion that cooperates with the toothed ring, which effectively prevents shaking and displacement during use, and is easy to disassemble and assemble.
[0024] 6. The telescopic mechanism of this utility model uses a second bolt to fix the guide rod and a third bolt to position the ball, ensuring the stability of the entire support during use and guaranteeing the safety of the patient during the rehabilitation process. Attached Figure Description

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0031] Please see Figures 1 to 3 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance.

[0032] This utility model provides a technical solution: an orthopedic clinical displacement stent, comprising two symmetrically arranged annular guide rails 1, which are the basic support structure of the entire device. A toothed ring 101 is fixedly sleeved on the outer wall of the annular guide rail 1, playing a key role in the operation of the position adjustment mechanism 2.
[0033] The position adjustment mechanism 2 includes a rectangular block 201, a stepped block 202, and an adjusting gear 203. The bottom of the rectangular block 201 is hinged to the stepped block 202, which can be locked to it. Both the bottom of the rectangular block 201 and the top of the stepped block 202 have arc-shaped grooves, which are slidably connected to the outer wall of the annular guide rail 1, allowing the position adjustment mechanism 2 to move along the annular guide rail 1. A rotatable adjusting gear 203 is mounted on the rectangular block 201, which meshes with the gear ring 101.
[0034] A first bolt 204 is vertically and downwardly connected to the top surface of the rectangular block 201, and the bottom of the first bolt 204 is threadedly connected to the top surface of the stepped block 202. When it is necessary to fix the relative position of the rectangular block 201 and the stepped block 202, tighten the first bolt 204 to lock them tightly, ensuring the stability of the position adjustment mechanism 2 during use.
[0035] The bottom of the rectangular block 201 and the top surface of the stepped block 202 are respectively fixedly connected with limiting protrusions 209 that slide with the upper and lower surfaces of the toothed ring 101. These limiting protrusions 209 can prevent the position adjustment mechanism 2 from unnecessary shaking or deviation during movement along the annular guide rail 1 or during use, further improving its operational stability and accuracy.
[0036] A rotating shaft 205 is vertically rotatably connected to the top surface of the rectangular block 201. A cylindrical head 206 is fixedly connected to the top of the rotating shaft 205, facilitating rotation by the operator. The outer wall of the rotating shaft 205, located below the rectangular block 201, is fixedly sleeved with the inner wall of the adjusting gear 203. When the position of the position adjustment mechanism 2 on the annular guide rail 1 needs to be adjusted, the operator rotates the cylindrical head 206 to drive the rotating shaft 205 to rotate, thereby causing the adjusting gear 203 to roll along the gear ring 101, thus moving the entire position adjustment mechanism 2 to the appropriate position along the annular guide rail 1.
[0037] The clamping assembly 3 includes a lead screw 207 threaded through the side wall of the stepped block 202. One end of the lead screw 207, located inside the annular guide rail 1, is rotatably connected to an arc-shaped clamping block 208. When it is necessary to fix the patient's leg, rotating the lead screw 207 moves the arc-shaped clamping block 208 toward the patient's leg, clamping the patient's leg using the arc-shaped surface of the clamping block 208. The degree of rotation of the lead screw 207 can be adjusted appropriately according to the thickness of the patient's leg and the required fixation force.
[0038] The telescopic mechanism 4 includes two spheres 401 arranged vertically and rotatably embedded in the bottom of the step block 202, which are used to achieve omnidirectional rotation of the spheres 401. This omnidirectional rotation structure allows the angle and relative position of the two annular guide rails 1 to be freely adjusted within a certain range to adapt to the special needs of different patients' body postures and fracture sites.
[0039] One of the spheres 401 is fixedly connected to a guide rod 402, and the other sphere 401 is fixedly connected to a sleeve 403 that slides onto the outer wall of the guide rod 402. This structure allows for adjustment of the distance between the two annular guide rails 1. A three-way pipe 404 that slides onto the outer wall of the guide rod 402 is fixedly connected to the end of the sleeve 403. A second bolt 405 is threaded onto the inner wall of the side opening of the three-way pipe 404, and the end of the second bolt 405 is pressed against the outer wall of the guide rod 402. After adjusting the distance between the two annular guide rails 1, tightening the second bolt 405 fixes the guide rod 402, ensuring the telescopic mechanism 4 maintains a stable length, thereby fixing the distance between the two annular guide rails 1.
[0040] The side wall of the step block 202 is threaded with a third bolt 406, the end of which is pressed against the outer wall of the ball 401. After adjusting the angle of the ball 401, tightening the third bolt 406 can position the ball 401, preventing unnecessary rotation during use and ensuring the stability of the entire telescopic mechanism 4.
[0041] Bone pins can also be installed on the outer walls of the guide rod 402 and the sleeve 403, and the position of the bone pins can be adjusted by adjusting the position adjustment mechanism 2.
[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
