Description

Technical Field

[0001] This invention relates to the field of surgical supports, and more particularly to a surgical limb support. Background Technology

[0002] A surgical limb support is a medical device used to support and immobilize a patient's limb during surgery. These supports are typically used in surgeries requiring precise manipulation of the limb, such as hip replacements, thigh or knee surgeries.

[0003] Patent No. 202311143552.3 describes "a limb support for the operating room and its method of use." The base can be moved horizontally by the rolling of the casters, allowing the operator to quickly adjust the working position of the base in the operating room. The operator then activates a cylinder on top of the base, and the cylinder's extension and retraction movement raises and lowers the support and adjustment discs. After the height of the support body on the top of the adjustment disc is adjusted, the operator grasps the first handle and pulls down the insertion rod. As the rod moves downward, it compresses the return spring, and after the rod is completely disengaged from the positioning hole, the fixed state between the support and adjustment discs is released. The operator then grasps the adjustment handle and the anti-slip protrusion and quickly rotates the adjustment disc. The horizontal position of the support body changes according to the rotation of the adjustment disc. Once the horizontal position of the support body is confirmed, the operator releases the first handle, and the insertion rod... Under the action of the return spring, the support body passes through the limiting hole and positioning hole again and is inserted into the adjusting disc. The operator then adjusts the support angle of the support body according to the actual situation of the operating room. After the hydraulic jack is started, it can drive the support body away from the support block to move up and down. The support block at the bottom of the support body is driven to rotate the shaft, so the support angle of the support body can be slowly adjusted. Then the patient can put the limb into the support body. The operator then starts the micro air pump. The micro air pump can first draw in outside air through the air inlet pipe and start the solenoid valve inside the air delivery pipe. The micro air pump then inflates the elastic airbags in one direction through the air delivery pipe. After the two elastic airbags inside the support body are inflated, they can tightly clamp the patient's limb. When the patient's limb needs to be released, the operator starts the solenoid valve inside the exhaust pipe and squeezes the elastic airbag. Then the gas inside the elastic airbag can be discharged outward in one direction through the exhaust pipe.

[0004] However, the following defects and shortcomings still exist in the application implementation process:

[0005] This device needs to be used in conjunction with a bottom movable support structure. In the relatively limited environment of the operating room, it will occupy a certain amount of space and have a certain impact on the movement of medical staff.

[0006] Therefore, it is necessary to provide a new surgical limb support to solve the above-mentioned technical problems. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0046] Please see Figures 1 to 8 The present invention provides a surgical limb support, which includes a support structure, an auxiliary fixation component 3, a rotating arm 4, and a bracket 5.

[0047] For the supporting structure;

[0048] Please see Figure 1 and Figure 2 The support structure includes a base 1, with multiple casters 11 installed at the lower end of the base 1, and a support rod 12 fixed at the upper end. The support rod 12 has a sliding cavity that extends through the upper end, and an axially telescopic extension rod 2 is installed inside the sliding cavity. A tightening bolt 13 that can abut against the extension rod 2 is also threaded onto the support rod 12.

[0049] It should be noted that in this device, a support rod 12 and an extension rod 2 are provided on the base 1. Together, they form a support structure. The extension rod 2 can move axially relative to the support rod 12, thereby adjusting the support height of the entire device to be adjusted according to the patient's limb elevation height, thus improving the comfort of use. At the same time, the extension rod 2 can be directly removed from the support rod 12. After removal, the extension rod 2 can be used as the support structure alone. At this time, it can be fixed to the operating table using the auxiliary fixing component 3. Therefore, it has more usage options, and the specific choice can be made according to the type of surgery and the operating room environment.

[0050] A caster wheel 11 is provided at the lower end of the base 1 to assist in the movement of the device. That is, when the support rod 12 is used in conjunction with the extension rod 2, it is convenient to adjust the placement position of the device.

[0051] For auxiliary fixing component 3;

[0052] Please see Figure 3 and Figure 4 The auxiliary fixing component 3 is fixed on the extension rod 2, including a positioning plate 31. A first clamping seat 32 and a second clamping seat 34 are respectively provided on both sides of the positioning plate 31. A clamping plate 35 is rotatably connected to both the first clamping seat 32 and the second clamping seat 34, and forms a clamping head with the clamping seat.

[0053] A connecting seat 33 is welded and fixed to one side of the first clamping seat 32, and the connecting seat 33 is fixed to the positioning plate 31 by bolts;

[0054] A threaded rod 36 is vertically welded to one side of the second clamping seat 34. The threaded rod 36 passes through the positioning plate 31 and is fixed by a dovetail nut, so that the second clamping seat 34 can rotate circumferentially relative to the positioning plate 31 with the threaded rod 36 as the axis.

[0055] It should be noted that: for the auxiliary fixing component 3, both the first clamping seat 32 and the second clamping seat 34 have clamping plates 35 to form two clamping heads. One of the clamping heads is fixed to the positioning plate 31 by bolts. The clamping head can be fixed to the extension rod 2 to ensure its stability. At the same time, the position of the clamping head on the extension rod 2 can be adjusted.

[0056] The other clamp is used to fix it to the bed. It has a threaded rod 36, which is fixed to the positioning plate 31 by a dovetail nut. This ensures its stability and allows the clamp to be rotated and adjusted according to the angle and position of the carrier on the bed, so that the extension rod 2 can remain vertical.

[0057] Please see Figure 3 and Figure 4 An engaging component 37 is also provided between the positioning plate 31 and the second clamping seat 34;

[0058] The engaging component 37 includes a first mating plate 371 and a second mating plate 372. The first mating plate 371 is welded and fixed to the positioning plate 31, while the second mating plate 372 is welded to the second clamping seat 34. Both are concentrically arranged with the threaded rod 36. The first mating plate 371 and the second mating plate 372 have teeth 373 on opposite sides, and the teeth 373 can engage and fix each other. The first mating plate 371 and the second mating plate 372 have grooves on opposite sides. A first spring 374 is also sleeved on the threaded rod 36, located inside the grooves, and abuts against the first mating plate 371 and the second mating plate 372.

[0059] It should be noted that the biting component 37 is used to reinforce the connection between the positioning plate 31 and the second clamping seat 34. That is, when the teeth 373 in the first mating plate 371 and the second mating plate 372 are engaged, it can further restrict the second clamping seat 34, making it more stable and preventing it from rotating.

[0060] When the second clamping seat 34 needs to be rotated and adjusted, it first contacts the dovetail nut to restrict the threaded rod 36. Under the elastic force of the first spring 374, it can push open the first mating plate 371 and the second mating plate 372. When the two are in a non-engaged state, the second clamping seat 34 can be rotated and adjusted.

[0061] For the self-locking rotating component 41;

[0062] Please see Figures 5 to 8 The self-locking rotating component 41 includes a first positioning cylinder 411, and the inner circumference of the first positioning cylinder 411 is also provided with a plurality of annularly distributed grooves 412. The connecting rod 42 is welded and fixed to the outer circumference of the first positioning cylinder 411.

[0063] A second positioning cylinder 414 is rotatably connected inside the first positioning cylinder 411. The second positioning cylinder 414 has multiple annularly distributed through holes 415 on its circumferential sidewall, which can correspond to the groove 412.

[0064] Both ends of the second positioning cylinder 414 are detachably connected to end seats 417. A smooth rod 4110, concentrically arranged with the second positioning cylinder 414, is fixed between the two end seats 417. Two symmetrically arranged slides 4111 are slidably connected to the smooth rod 4110. A second spring 4116 is also sleeved between the slides 4111 and the end seats 417. Multiple annularly distributed first hinge seats 4112 are welded and fixed on the slides 4111. A support plate 4113 is rotatably connected to the first hinge seat 4112. A second hinge seat 4115 is rotatably connected to the other end of the support plate 4113. An insert 4114 is welded and fixed to one side of the second hinge seat 4115.

[0065] The insert 4114 is slidably connected to the inside of the through-hole 415 and can be inserted into the through-hole 415 and embedded in the inside of the groove 412.

[0066] One of the self-locking rotating parts 41 has its end seat 417 screwed to one end of the extension rod 2, while the other self-locking rotating part 41 has its end seat 417 screwed to the bracket 5.

[0067] It should be noted that: in the self-locking rotating component 41, the first positioning cylinder 411 and the second positioning cylinder 414 can rotate relative to each other. There are two sets of self-locking rotating components 41. One set of self-locking rotating components 41 is fixed to the extension rod 2 with the second positioning cylinder 414 as the fixed base, so that the first positioning cylinder 411 can rotate; while in the other set of self-locking rotating components 41, the first positioning cylinder 411 is fixed to the connecting rod 42 with the first positioning cylinder 411 as the fixed base, and the bracket 5 can be fixed to its second positioning cylinder 414, so that the bracket 5 can rotate. Therefore, the bracket 5 can be rotated and adjusted so that it can better cooperate with the patient's limb.

[0068] The first positioning cylinder 411 has a groove 412 inside. Under normal conditions, the insert 4114 is embedded in the groove 412, which can restrict the first positioning cylinder 411 and the second positioning cylinder 414 and keep them stable.

[0069] Under the action of external force, the first positioning cylinder 411 and the second positioning cylinder 414 rotate relative to each other. At this time, the insert 4114 is squeezed due to being disengaged from the groove 412, and moves radially until it corresponds to the groove 412 again. Then, the elastic force of the second spring 4116 causes the insert 4114 to be re-embedded into the groove 412. Therefore, the rotation between the two can be guaranteed. At the same time, it has a self-locking function. After locking, the bracket 5 can have sufficient stability and avoid rotation when supporting the limb.

[0070] Please see Figures 5 to 7 The inner circumferential wall of the first positioning cylinder 411, away from the center, is integrally connected with an insert ring 413, while the outer circumferential wall of the second positioning cylinder 414 is provided with a corresponding annular groove 416, and the insert ring 413 is embedded in the annular groove 416.

[0071] It should be noted that the embedded ring 413 on the first positioning cylinder 411 is embedded in the annular groove 416 on the outside of the second positioning cylinder 414, which can enhance the connection between the two and make it more stable.

[0072] Please see Figure 7 and Figure 8 One end of the end seat 417 is welded and fixed with a connecting frame 418. The connecting frame 418 is threaded to the end of the second positioning cylinder 414. The connecting frame 418 has a positioning hole 419, and the end of the smooth rod 4110 is inserted into the positioning hole 419.

[0073] It should be noted that the end seat 417 and the second positioning cylinder 414 are detachably connected. After disassembling them, the internal structures of the second positioning cylinder 414 can be disassembled for easy maintenance.

[0074] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
