[0003] In the prior art, before hospital medical staff perform orthopedic surgery on a patient's arm or leg, an assistant is required to lift the patient's arm or leg and then wipe the skin of the arm or leg with iodine to complete the disinfection. However, lifting the patient's arm or leg for a long time requires the assistant to expend a lot of physical strength, and it is impossible to ensure that the assistant can assist the surgeon in subsequent operations. Therefore, a tool for assisting the disinfection of limbs in orthopedic surgery is proposed to solve the above problem. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a tool for assisting in the disinfection of limbs in orthopedic surgery, which has the advantages of not requiring the assistant to expend a lot of physical strength to lift the patient's arm or leg for a long time, and then allowing the assistant to maintain sufficient physical strength to assist the surgeon in subsequent operations. This solves the problem in the prior art that before hospital medical staff perform orthopedic surgery on the patient's arm or leg, the assistant is required to lift the patient's arm or leg and then wipe the skin of the arm or leg with iodine to complete the disinfection, but lifting the patient's arm or leg for a long time requires the assistant to expend a lot of physical strength, and it is impossible to ensure that the assistant can assist the surgeon in subsequent operations.

[0006] (II) Technical solution

[0007] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a tool for assisting limb disinfection in orthopedic surgery comprises an operating bed, the operating bed comprises a pillar and a bed board, the left side of the pillar is fixedly connected with a rotating seat, the interior of the rotating seat is rotatably connected with a rotating tube extending to its front side, the front side of the rotating tube is rotatably connected with a first threaded rod extending to its rear side, the outer side of the first threaded rod is provided with a locking assembly which is threadedly connected with it and fixedly connected with the rear side of the rotating tube and tightly fitted with the inner wall of the rotating seat, the left side of the rotating tube is provided with a telescopic assembly, the left side of the telescopic assembly is provided with an axis core, the outer side of the axis core is rotatably connected with a rotating sleeve, the left side of the rotating sleeve is fixedly connected with a first rubber ring, the left side of the axis core is provided with a limit assembly adapted to the first rubber ring, the rear side of the rotating sleeve is fixedly connected with a mounting shaft, and the outer side of the mounting shaft is provided with a bracket assembly.

[0008] The beneficial effect of the utility model is as follows: when it is necessary to disinfect the patient's arm or leg, first, the first threaded rod is rotated to drive the locking assembly to separate from the inner wall of the rotating seat, and then the lock of the rotating tube and the rotating seat is unlocked. After the rotating tube is rotated to a position suitable for the patient, the first threaded rod is rotated again to make the locking assembly fit tightly with the inner wall of the rotating seat, and the rotating tube rotated to a suitable position is locked, and then the telescopic assembly is unfolded, and the telescopic assembly drives the installation shaft to move until the telescopic assembly drives the installation shaft to extend to a length suitable for the patient, so that the installation shaft rotates around the axis core until the patient can place the arm or leg on the top of the installation shaft, and then the limiting assembly is rotated to make it fit tightly with the first rubber ring, so that the installation shaft is limited relative to the position of the telescopic assembly, the bracket assembly is moved to an appropriate position, and the patient's arm or leg is placed on the top of the bracket assembly to disinfect the patient's arm or leg.

[0009] This tool for assisting in the disinfection of limbs during orthopedic surgery has the advantage of not requiring the assistant to expend a great deal of physical strength to lift the patient's arms or legs for a long time, thereby enabling the assistant to maintain sufficient physical strength to assist the surgeon in subsequent operations.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the locking assembly includes an internal threaded ring, a fixed ring, a connecting rod and a contact block, the outer side of the first threaded rod is threadedly connected to the internal threaded ring, the rear side of the rotating tube is fixedly connected to the fixed ring, the outer sides of the internal threaded ring and the fixed ring are hinged with connecting rods distributed in a circular array and adapted to each other, the opposite side of the connecting rod is hinged with the same contact block, the contact blocks are tightly fitted with the inner wall of the rotating seat, and the opposite side of the contact block is roughened.

[0012] The beneficial effect of adopting the above further scheme is that when the first threaded rod is rotated, the force generated by the rotation of the thread drives the internal threaded ring to move forward or backward. When the internal threaded ring moves forward, that is, the internal threaded ring moves toward the fixed ring, then the connecting rod presses the contact block against the inner wall of the rotating seat and fits tightly. The rough treatment on the opposite side of the contact block can provide sufficient friction between it and the inner wall of the rotating seat, so that the rotating tube can be locked. When the internal threaded ring moves backward, that is, the internal threaded ring gradually moves away from the fixed ring, and then the contact block is separated from the inner wall of the rotating seat, the rotating tube can be released.

[0013] Furthermore, the telescopic assembly includes a sliding shaft, a sliding sleeve and a first limit screw. The sliding shaft is fixedly connected to the left side of the rotating tube, the sliding sleeve is slidably connected to the outer side of the sliding shaft, the front side of the sliding sleeve is threadedly connected to the first limit screw that fits tightly with the outer side of the sliding shaft, and the left side of the sliding sleeve is fixedly connected to the shaft core.

[0014] The beneficial effect of adopting the above further scheme is that the first limit screw is rotated to separate the first limit screw from the sliding shaft, and then the sliding sleeve is pulled, and the sliding sleeve drives the installation shaft to move until the sliding sleeve drives the installation shaft to extend to a length suitable for the patient, thereby rotating the first limit screw to make the first limit screw close to the sliding shaft.

[0015] Furthermore, the limiting assembly includes a second threaded rod, a spring, a pressing plate, an internally threaded cylinder and a second rubber ring. The left side of the shaft core is fixedly connected to the second threaded rod, the left side of the shaft core is fixedly connected to the spring located on the outside of the second threaded rod, the outside of the second threaded rod is slidably connected to a pressing plate fixedly connected to the left side of the spring, the outside of the second threaded rod is threadedly connected to an internally threaded cylinder in contact with the left side of the pressing plate, and the right side of the pressing plate is fixedly connected to a second rubber ring adapted to the first rubber ring.

[0016] The beneficial effect of adopting the above further scheme is that the installation shaft is rotated around the axis core until the patient can place his arm or leg on the top of the installation shaft, and then the internal threaded cylinder is rotated. The force generated by the rotation of the thread causes the internal threaded cylinder to push the pressing piece to slide toward the first rubber ring until the second rubber ring is tightly fitted with the first rubber ring and the internal threaded cylinder is stopped from rotating, so that the position of the installation shaft relative to the sliding sleeve can be limited.

[0017] Furthermore, the bracket assembly includes a movable sleeve, a second limit screw and a V-shaped leather frame. The outer side of the mounting shaft is movably connected to the movable sleeve, the left side of the movable sleeve is threadedly connected to the second limit screw that fits tightly with the outer side of the mounting shaft, and the top of the movable sleeve is fixedly connected to the V-shaped leather frame.

[0018] The beneficial effect of adopting the above further scheme is that the second limit screw is rotated to separate the second limit screw from the outer side of the mounting shaft, and then the movable sleeve is rotated and slid until the patient's arm or leg can be placed on the top of the V-shaped cortical frame, and the second limit screw is rotated to make it close to the outer side of the mounting shaft, so as to limit the V-shaped cortical frame to adapt to patients of different body shapes.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the embodiment, Figure 1-7 Provided is a tool for assisting limb disinfection in orthopedic surgery. The utility model comprises an operating bed 1, the operating bed 1 comprises a pillar 2 and a bed board 3, a rotating seat 4 is fixedly connected to the left side of the pillar 2, a rotating tube 5 extending to the front side of the rotating seat 4 is rotatably connected inside the rotating seat 4, a first threaded rod 6 extending to the rear side of the rotating tube 5 is rotatably connected to the front side of the rotating tube 5, a locking assembly 7 is provided on the outer side of the first threaded rod 6, which is threadedly connected to the rotating tube 5 and fixedly connected to the rear side of the rotating tube 5 and tightly fitted to the inner wall of the rotating seat 4, a telescopic assembly 8 is provided on the left side of the rotating tube 5, an axis core 9 is provided on the left side of the telescopic assembly 8, a rotating sleeve 10 is rotatably connected to the outer side of the axis core 9, a first rubber ring 11 is fixedly connected to the left side of the rotating sleeve 10, a limiting assembly 12 adapted to the first rubber ring 11 is provided on the left side of the axis core 9, a mounting shaft 13 is fixedly connected to the rear side of the rotating sleeve 10, a bracket assembly 14 is provided on the outer side of the mounting shaft 13;

[0029] The locking assembly 7 includes an internal threaded ring 701, a fixing ring 702, a connecting rod 703 and a contact block 704. The outer side of the first threaded rod 6 is threadedly connected with the internal threaded ring 701. The rear side of the rotating tube 5 is fixedly connected with the fixing ring 702. The outer sides of the internal threaded ring 701 and the fixing ring 702 are both hinged with connecting rods 703 distributed in an annular array and adapted to each other. The opposite side of the connecting rod 703 is hinged with the same contact block 704. The contact blocks 704 are tightly fitted with the inner wall of the rotating seat 4. The opposite side of the contact blocks 704 is roughened.

[0030] The first threaded rod 6 is rotated, and the force generated by the rotation of the thread drives the internal thread ring 701 to move forward or backward. When the internal thread ring 701 moves forward, that is, the internal thread ring 701 moves toward the fixed ring 702, then the connecting rod 703 pushes the contact block 704 against the inner wall of the rotating seat 4 and fits tightly. The rough treatment on the opposite side of the contact block 704 can provide sufficient friction between it and the inner wall of the rotating seat 4, so that the rotating tube 5 can be locked. When the internal thread ring 701 moves backward, that is, the internal thread ring 701 gradually moves away from the fixed ring 702, then the contact block 704 is separated from the inner wall of the rotating seat 4, and the locking of the rotating tube 5 can be released;

[0031] The telescopic assembly 8 includes a sliding shaft 801, a sliding sleeve 802 and a first stop screw 803. The left side of the rotating tube 5 is fixedly connected with the sliding shaft 801, the outer side of the sliding shaft 801 is slidably connected with the sliding sleeve 802, the front side of the sliding sleeve 802 is threadedly connected with the first stop screw 803 that is tightly fitted with the outer side of the sliding shaft 801, and the left side of the sliding sleeve 802 is fixedly connected with the shaft core 9;

[0032] The first limiting screw 803 is rotated to separate the first limiting screw 803 from the sliding shaft 801, and then the sliding sleeve 802 is pulled, and the sliding sleeve 802 drives the installation shaft 13 to move until the sliding sleeve 802 drives the installation shaft 13 to extend to a length suitable for the patient, thereby rotating the first limiting screw 803 to make the first limiting screw 803 and the sliding shaft 801 close to each other;

[0033] The limiting assembly 12 includes a second threaded rod 121, a spring 122, a pressing piece 123, an internal threaded barrel 124 and a second rubber ring 125. The left side of the shaft core 9 is fixedly connected with the second threaded rod 121, the left side of the shaft core 9 is fixedly connected with the spring 122 located outside the second threaded rod 121, the outer side of the second threaded rod 121 is slidably connected with the pressing piece 123 fixedly connected to the left side of the spring 122, the outer side of the second threaded rod 121 is threadedly connected with the internal threaded barrel 124 in contact with the left side of the pressing piece 123, and the right side of the pressing piece 123 is fixedly connected with the second rubber ring 125 adapted to the first rubber ring 11;

[0034] The installation shaft 13 is rotated around the shaft core 9 until the patient can place his arm or leg on the top of the installation shaft 13, and then the internal threaded cylinder 124 is rotated. The force generated by the rotation of the thread causes the internal threaded cylinder 124 to push the pressing piece 123 to slide toward the first rubber ring 11 until the second rubber ring 125 is tightly fitted with the first rubber ring 11. Then, the rotation of the internal threaded cylinder 124 is stopped, and the position of the installation shaft 13 relative to the sliding sleeve 802 is limited.

[0035] The bracket assembly 14 includes a movable sleeve 141, a second limit screw 142 and a V-shaped cortical frame 143. The outer side of the installation shaft 13 is movably connected with the movable sleeve 141. The left side of the movable sleeve 141 is threadedly connected with the second limit screw 142 that fits tightly with the outer side of the installation shaft 13. The top of the movable sleeve 141 is fixedly connected with the V-shaped cortical frame 143.

[0036] The second limit screw 142 is rotated to separate the second limit screw 142 from the outer side of the installation shaft 13, and then the movable sleeve 141 is rotated and slid until the patient's arm or leg can be placed on the top of the V-shaped cortical frame 143, so that the second limit screw 142 is rotated to make it close to the outer side of the installation shaft 13, and the V-shaped cortical frame 143 is limited to adapt to patients of different body shapes.

[0037] Working principle:

[0038] Step 1: When the patient's arm or leg needs to be disinfected, first, rotate the first threaded rod 6. The force generated by the rotation of the thread drives the internal threaded ring 701 to move backward, that is, the internal threaded ring 701 gradually moves away from the fixed ring 702, and then the contact block 704 is separated from the inner wall of the rotating seat 4, so that the rotation tube 5 can be unlocked. After the rotating tube 5 is rotated to a position suitable for the patient, the first threaded rod 6 is rotated again. The force generated by the rotation of the thread drives the internal threaded ring 701 to move forward, that is, the internal threaded ring 701 moves toward the fixed ring 702. Then, the connecting rod 703 pushes the contact block 704 against the inner wall of the rotating seat 4 and fits tightly. The rough treatment on the opposite side of the contact block 704 can provide sufficient friction between it and the inner wall of the rotating seat 4, so that the rotating tube 5 can be locked;

[0039] Step 2: Rotate the first limiting screw 803 to separate the first limiting screw 803 from the sliding shaft 801, and then pull the sliding sleeve 802, so that the sliding sleeve 802 drives the installation shaft 13 to move until the sliding sleeve 802 drives the installation shaft 13 to extend to a length suitable for the patient, thereby rotating the first limiting screw 803 to make the first limiting screw 803 and the sliding shaft 801 close to each other;

[0040] The third step: rotate the installation shaft 13 around the axis core 9 until the patient can place his arm or leg on the top of the installation shaft 13, and then rotate the internal threaded tube 124. The force generated by the rotation of the thread causes the internal threaded tube 124 to push the pressing piece 123 to slide toward the first rubber ring 11 until the second rubber ring 125 is tightly fitted with the first rubber ring 11, and then stop rotating the internal threaded tube 124. This can limit the position of the installation shaft 13 relative to the sliding sleeve 802, and then rotate the second limit screw 142 to separate the second limit screw 142 from the outside of the installation shaft 13, and then rotate and slide the movable sleeve 141 until the patient's arm or leg can be placed on the top of the V-shaped cortical frame 143, thereby rotating the second limit screw 142 to make it close to the outside of the installation shaft 13, limiting the V-shaped cortical frame 143, placing the patient's arm or leg on the top of the V-shaped cortical frame 143, and disinfecting the patient's arm or leg.
