Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a surgical lower limb support brace. Background Technology

[0002] In clinical practice, surgery in the lithotomy position requires the use of a support to elevate the patient's lower limbs, facilitating full exposure of the anus, perineum, and other surgical sites, thus aiding in the procedure. Currently, the lower limb support braces used clinically consist of a small, arc-shaped plate brace placed against the popliteal fossa behind the knee joint, supporting part of the lower leg. To facilitate adjustment of the brace position to accommodate patients of different body types, existing lower limb braces generally consist of a support rod and a fixed base. The fixed base is movably connected to the operating table via a sliding rail, while the support rod can be adjusted by sliding or rotating relative to the fixed base. However, existing support rods are typically bare rods to facilitate sliding relative to the fixed base. Therefore, even after the nursing staff has adjusted the brace position and locked the fixed base and support rod together using the locking device on the fixed base, the support rod may still slide down relative to the fixed base during surgery due to the actions of the medical staff, thus changing the patient's position and affecting the surgery. Therefore, we propose a surgical lower limb support brace. Summary of the Invention

[0003] One of the technical problems this application aims to solve is: how to design a lower limb support brace to prevent slippage.

[0004] To address the aforementioned technical problems, this application provides a surgical lower limb support bracket, including a fixation base, a slide rail, a supporting arc plate, and a support rod connected to the supporting arc plate, and further comprising:

[0005] A rotating cylinder is connected to a fixed base and rotates relative to the fixed base;

[0006] A through hole is provided on the rotating cylinder, and the support rod slides through the through hole;

[0007] Annular grooves, wherein multiple annular grooves are provided and are evenly spaced on the support rod;

[0008] An arc-shaped clamping plate is provided in a fixed base, with one end of the arc-shaped clamping plate passing through the fixed base and located in a through hole. One end of the arc-shaped clamping plate is located in an annular groove. A movable support rod pushes the arc-shaped clamping plate to move and disengage from the annular groove.

[0009] An extrusion plate, wherein the extrusion plate is disposed inside a rotating cylinder;

[0010] Auxiliary components are used to move the extrusion plate so that the extrusion plate contacts and presses against the support rod.

[0011] The linkage component is used to connect the extrusion plate and the arc-shaped clamping plate. Moving the extrusion plate causes the arc-shaped clamping plate to move and embed into the annular groove to limit and lock the support rod.

[0012] In some embodiments, a round rod is provided on one side of the arc-shaped plate, and a sliding plate is provided at one end of the round rod. The sliding plate is connected to a rotating cylinder, and one end of the round rod slides through the sliding plate. A spring is sleeved on the round rod, and the contact surface between the arc-shaped plate and the annular groove is chamfered. The moving support rod pushes the arc-shaped plate to move, while compressing the spring.

[0013] In some embodiments, the auxiliary component includes a cylinder disposed on one side of the extrusion plate, a screw disposed on the cylinder, one end of the screw passing through the rotating cylinder and disposed on a turntable, rotating the turntable causing the extrusion plate to move and press the support rod.

[0014] In some embodiments, the linkage component includes an L-shaped rod disposed on one side of the extrusion plate, and a connecting rod is provided between the L-shaped rod and the sliding plate. The two ends of the connecting rod rotate relative to the sliding plate and the L-shaped rod, respectively. Moving the extrusion plate causes the sliding plate to move, and a spring pushes the arc-shaped clamping plate to move.

[0015] In some embodiments, an annular protrusion is provided on one side of the fixed base, one end of the annular protrusion is located inside the rotating cylinder, and an annular limiting plate is provided at one end of the annular protrusion.

[0016] A force-bearing plate is provided inside the rotating cylinder. One end of the force-bearing plate passes through the through hole and contacts the support rod. A locking element is provided on one side of the force-bearing plate. The pressing plate is moved to press the support rod so that the force-bearing plate moves. The locking element locks the rotating cylinder and the fixed seat at the same time.

[0017] The fixed base is equipped with a second locking element. By moving the force plate, the second locking element locks the fixed base and the slide rail.

[0018] In some embodiments, one side of the extrusion plate is designed with an arc shape, and one side of the force-bearing plate is also designed with an arc shape;

[0019] The contact surface between the extrusion plate and the support rod is made of rubber, and the contact surface between the force-bearing plate and the support rod is also made of rubber.

[0020] In some embodiments, the locking element one includes a cylindrical rod disposed on one side of the force plate, and a spring two is sleeved on the cylindrical rod, the spring two contacting and abutting against the inner wall of the rotating cylinder;

[0021] The fixed base is provided with a ring body one, and a ring body two is provided at one end of the cylindrical rod. The ring body one has multiple slots evenly spaced, and the ring body two has multiple protrusions evenly spaced. In the initial state of the spring two, the multiple protrusions are away from the multiple slots. Moving the support rod and pressing the force plate causes the ring body two to move, so that the multiple protrusions are inserted into the multiple slots to lock the rotating cylinder and the fixed base. At the same time, the spring two is compressed and contracts to provide self-restoring energy.

[0022] In some embodiments, the second locking member includes a top rod disposed on one side of the force-bearing plate. One end of the top rod passes through a rotating cylinder and a fixed seat in sequence. A friction plate is disposed on one end of the top rod. Moving the force-bearing plate causes the friction plate to move and press against the slide rail.

[0023] In some embodiments, a limiting arc plate is provided inside the rotating cylinder, a trapezoidal protrusion is provided inside the fixed seat, and a synchronization component is provided between the trapezoidal protrusion and the limiting arc plate. The fixed seat is removed relative to the slide rail so that the trapezoidal protrusion pops out of the fixed seat, and the limiting arc plate is moved by the synchronization component so that the limiting arc plate is inserted into the annular groove.

[0024] In some embodiments, the synchronization component includes a guide rod disposed at one end of the limiting arc plate, a spring three sleeved on the guide rod, a connecting plate disposed on the guide rod, and a push rod disposed on the connecting plate. The push rod is pushed to drive the limiting arc plate to disengage from the annular groove, while the spring three is compressed under force to provide it with self-recovery capability.

[0025] A sliding ring is provided on the fixed seat. One end of the sliding ring contacts the end of the push rod, and a connecting post is provided on one side of the sliding ring. The connecting post passes through the fixed seat and is fixed to the trapezoidal protrusion. The fixed seat is installed on the slide rail, which pushes the trapezoidal protrusion to move, thereby driving the push rod to move.

[0026] This invention has at least the following beneficial effects:

[0027] The support rod can be temporarily locked by the combination of the arc-shaped locking plate and the spring, making it convenient for medical staff to adjust the height of the support rod;

[0028] While the auxiliary component drives the compression plate to press and fix the support frame, the linkage component drives the arc-shaped clamping plate to be further inserted into the annular groove, thereby completely locking the support rod, preventing it from sliding down relative to the fixed seat, avoiding changes in the patient's position, and ensuring the normal operation of the surgery.

[0029] At the same time, with a locking action by medical staff, the adjustable position of the stent can be locked using locking device one and locking device two, which is convenient and quick.

[0030] At the same time, the trapezoidal protrusion and the limiting arc plate are used to prevent the fixation seat from accidentally detaching from the support rod when medical staff move the main body of the stent, thus avoiding the problem of the fixation seat being lost. It also prevents the fixation seat from accidentally falling to the ground and causing damage to the fixation seat, which is quite practical. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] Please see Figures 1-7 The present invention provides a technical solution: a surgical lower limb support bracket, comprising a fixing base 1, a slide rail 11, a supporting arc plate 12, and a support rod 13 connected to the supporting arc plate 12, and further comprising:

[0044] Rotate cylinder 2, which is connected to fixed base 1. Rotate cylinder 2 and rotates relative to fixed base 1, thereby realizing the function of adjusting the angle of support rod 13 relative to fixed base 1. An annular protrusion 24 is fixedly connected to one side of fixed base 1. One end of an annular protrusion 24 is located inside the rotating cylinder 2 and is slidably connected to its inner wall. An annular limiting plate 25 is fixedly connected to one end of an annular protrusion 24. The annular limiting plate 25 is also located inside the rotating cylinder 2 and is slidably connected to its inner wall. Thus, the rotating cylinder 2 is connected to fixed base 1 through the annular limiting plate 25, and the rotating cylinder 2 can rotate relative to fixed base 1.

[0045] Through hole 3 is formed on the rotating cylinder 2, and the support rod 13 slides through through hole 3;

[0046] Annular grooves 4 are provided in multiples and are evenly spaced on the support rod 13. The design of the annular grooves 4 allows the support rod 13 to rotate 360 ​​degrees relative to the rotating cylinder 2, thereby improving the flexibility of the device. At the same time, the rotating cylinder 2 can also rotate 360 ​​degrees relative to the fixed seat 1, thereby driving the support arc plate 12 to adjust the angle, thereby further improving the flexibility of the device.

[0047] An arc-shaped clamping plate 5 is disposed within a fixed base 1, with one end of the arc-shaped clamping plate 5 passing through the fixed base 1 and located within a through hole 3. Another end of the arc-shaped clamping plate 5 is located within an annular groove 4. A movable support rod 13 pushes the arc-shaped clamping plate 5 to move and disengage from the annular groove 4. Specifically, a round rod 14 is fixedly connected to one side of the arc-shaped clamping plate 5, and a sliding plate 15 is provided at one end of the round rod 14. The sliding plate 15 is connected to a rotating cylinder 2, and one end of the round rod 14 slides through the sliding plate 15. A spring 1 is sleeved on the round rod 14. 6. One end of spring 16 is fixedly connected to sliding plate 15, and the other end is fixedly connected to arc-shaped clamping plate 5. The contact surface between arc-shaped clamping plate 5 and annular groove 4 is chamfered. Thus, in the initial state of spring 16, one end of arc-shaped clamping plate 5 is already located in annular groove 4, thereby using arc-shaped clamping plate 5 to temporarily support support rod 13. At this time, medical staff can rotate cylinder 2 to move support rod 13 and use arc-shaped clamping plate 5 and spring 16 to temporarily lock support rod 13.

[0048] The extrusion plate 6 is disposed inside the rotating cylinder 2 and is slidably connected to the inner wall of the rotating cylinder 2. One end of the extrusion plate 6 passes through the rotating cylinder 2 and is located inside the through hole 3.

[0049] The auxiliary component 7 is used to move the extrusion plate 6 so that the extrusion plate 6 contacts and presses the support rod 13. Specifically, the auxiliary component 7 includes a cylinder 17 fixedly connected to one side of the extrusion plate 6. A screw 18 is rotatably connected to the cylinder 17 via a rotating shaft. One end of the screw 18 passes through the rotating cylinder 2 and is threadedly connected to it. A turntable 19 is fixedly connected to one end of the screw 18. After the medical staff adjusts the height of the support rod 13, they can rotate the turntable 19 to drive the screw 18 to rotate, thereby driving the extrusion plate 6 to move, thus driving the extrusion plate 6 to press the support rod 13, thereby limiting and fixing the support rod 13 and preventing it from rotating or sliding relative to the rotating cylinder 2.

[0050] Linkage component 8 connects the compression plate 6 and the arc-shaped clamping plate 5. Moving the compression plate 6 causes the arc-shaped clamping plate 5 to move and embed into the annular groove 4, thereby limiting and locking the support rod 13. Specifically, the linkage component 8 includes an L-shaped rod 21 fixedly connected to one side of the compression plate 6. The L-shaped rod 21 is located inside the rotating cylinder 2 and slidably connected to its inner wall. A connecting rod 23 is provided between the L-shaped rod 21 and the sliding plate 15. The two ends of the connecting rod 23 are rotatably connected to the L-shaped rod 21 and the sliding plate 15 respectively through a rotating shaft. The two ends of the connecting rod 23 rotate relative to the sliding plate 15 and the L-shaped rod 21 respectively. When the medical staff moves the compression plate 6 to press and fix the support rod 13, it drives the L-shaped rod 21 to move, thereby driving the connecting rod 23 to move, and then driving the sliding plate 15 to move. This uses the spring 16 to push the arc-shaped clamping plate 5 to move, so that the arc-shaped clamping plate 5 is further inserted into the annular groove 4, thereby completely locking the support rod 13, preventing it from sliding down relative to the fixed seat 1, avoiding changes in the patient's position, and ensuring the normal operation of the surgery.

[0051] A force plate 26 is slidably connected inside the rotating cylinder 2. One end of the force plate 26 passes through the through hole 3 and contacts the support rod 13. A locking element 27 is provided on one side of the force plate 26. The moving pressing plate 6 presses the support rod 13, and the support rod 13 presses the force plate 26 to move. The locking element 27 locks the rotating cylinder 2 and the fixed seat 1 at the same time.

[0052] The fixed base 1 is equipped with a second locking element 28 and a movable force plate 26. The second locking element 28 is used to lock the fixed base 1 and the slide rail 11. Then, with a locking action by medical staff, all adjustable positions of the bracket can be locked, which is convenient and quick.

[0053] The extrusion plate 6 has an arc-shaped design on one side, and the force plate 26 also has an arc-shaped design on one side, so that the extrusion plate 6 and the force plate 26 fit the support rod 13 more closely, thereby improving the fixing effect of the extrusion plate 6 and the force plate 26 on the support rod 13.

[0054] The contact surfaces of the extrusion plate 6 and the support rod 13 are made of rubber, and the contact surfaces of the force plate 26 and the support rod 13 are also made of rubber, thereby further improving the fixing effect of the extrusion plate 6 and the force plate 26 on the support rod 13.

[0055] Locking component 27 includes a cylindrical rod 29 fixedly connected to one side of the force plate 26, and a spring 31 is sleeved on the cylindrical rod 29. The spring 31 contacts and abuts against the inner wall of the rotating cylinder 2.

[0056] A ring body 32 is fixedly connected inside the fixed base 1. A ring body 33 is fixedly connected to one end of the cylindrical rod 29. Multiple slots 34 are evenly spaced on the ring body 32. Multiple protrusions 35 are evenly spaced on one end of the ring body 33. In the initial state of the spring 31, the multiple protrusions 35 are far away from the multiple slots 34. When medical staff fix the support rod 13 by moving the compression plate 6, the support rod 13 moves and compresses the force plate 26, so that the ring body 33 moves, so that the multiple protrusions 35 are inserted into the multiple slots 34 to lock the rotating cylinder 2 and the fixed base 1, thereby preventing the rotating cylinder 2 from rotating relative to the fixed base 1. At the same time, the spring 31 is compressed and contracted to provide self-restoring ability.

[0057] Locking component 28 includes a top rod 36 fixedly connected to one side of the force plate 26. One end of the top rod 36 slides through the rotating cylinder 2 and the fixed seat 1 in sequence. A friction disc 37 is fixedly connected to one end of the top rod 36. In specific operation, when the medical staff rotates the rotating disk to move the compression plate 6, they simultaneously push the support rod 13 to move, thereby pushing the force plate 26 to move, and then pushing the annular body 2 to move, so that multiple locking protrusions 35 are inserted into multiple locking slots 34, and at the same time, the top rod 36 is moved, thereby driving the friction disc 37 to move and press against the slide rail 11, thereby locking the fixed seat 1 and the slide rail 11 synchronously.

[0058] Example 2

[0059] Please see Figures 1-9 The present invention provides a technical solution: a surgical lower limb support bracket, wherein embodiment 2 is an optimization based on embodiment 1;

[0060] A limiting arc plate 38 is slidably connected inside the rotating cylinder 2, and a trapezoidal protrusion 39 is slidably connected inside the fixed seat 1. A synchronization component 41 is provided between the trapezoidal protrusion 39 and the limiting arc plate 38. The fixed seat 1 is removed relative to the slide rail 11 so that the trapezoidal protrusion 39 pops out of the fixed seat 1. The synchronization component 41 drives the limiting arc plate 38 to move so that the limiting arc plate 38 is inserted into the annular groove 4. Specifically, the synchronization component 41 includes a guide rod 42 fixedly connected to one end of the limiting arc plate 38. A spring 43 is sleeved on the guide rod 42. The two ends of the spring 43 are in contact with the rotating cylinder 2 and the limiting arc plate 38 respectively. A connecting plate 44 is fixedly connected to the guide rod 42. A push rod 45 is fixedly connected to one end of the connecting plate 44. Pushing the push rod 45 drives the limiting arc plate 38 to disengage from the annular groove 4. At the same time, the spring 43 is compressed by force to provide self-recovery capability.

[0061] A sliding ring 46 is slidably connected to the fixed base 1. One end of the sliding ring 46 contacts and abuts against the end of the push rod 45. A connecting post 47 is fixedly connected to one side of the sliding ring 46. The connecting post 47 slides through the fixed base 1 and is fixedly connected to the trapezoidal protrusion 39. When medical staff connect the fixed base 1 to the slide rail 11, that is, when the bracket is installed and connected to the operating table, the slide rail 11 pushes the trapezoidal protrusion 39 to move, thereby driving the connecting post 47 to move, which in turn drives the sliding ring 46 to protrude out of the fixed base 1. The sliding ring 46 pushes the push rod 45 to move, thereby causing the limiting arc movement to retract into the inner wall of the rotating cylinder 2. At this time, medical staff can... The position of the support is adjusted by the free sliding of the support rod 13 relative to the rotating cylinder 2. Conversely, when medical staff remove the fixed seat 1 along with the support rod 13 from the slide rail 11, the trapezoidal protrusion 39 disengages from the slide rail 11. Then, the spring 33 resets and drives the limiting arc plate 38 to pop out, so that the limiting guard plate is inserted into the annular groove 4, thereby temporarily locking the fixed seat 1 and the support rod 13. Thus, when medical staff move the main body of the support, the fixed seat 1 will not be accidentally disengaged from the support rod 13, thereby avoiding the problem of the fixed seat 1 being lost. At the same time, it also avoids the problem of the fixed seat 1 accidentally falling to the ground and causing damage to the fixed seat 1, which is quite practical.
