Description

Technical Field

[0001] The invention relates to the field of operating tables, and in particular to an auxiliary adjustment table used for high-precision surgery in limb areas. Background Art

[0002] The highly refined surgical assisted adjustment bed used for upper limb axillary surgery has the characteristics of multi-dimensional adjustment, comfortable support, stable structure and safety assurance. It can provide good support and protection for surgery, improve the accuracy, efficiency and safety of surgery, and the bed surface material usually has good air permeability and softness to reduce the risk of pressure sores during prolonged surgery.

[0003] The auxiliary adjustment beds currently available on the market for high-precision limb area surgeries have many drawbacks in terms of arm fixation. In terms of fixation accuracy, traditional auxiliary adjustment beds usually lack effective fixation devices specifically for the patient's arms, which makes it easy for the patient's arms to move unconsciously during the operation, especially in some delicate surgical operations. This movement will cause serious interference to the accuracy of the operation. In terms of fit, the fixation method of traditional auxiliary adjustment beds is often relatively simple, and it is impossible to achieve multi-angle rotation to better fit the patient's arms, which will result in loose fixation or excessive pressure on the patient's arms, causing discomfort to the patient. For example, for patients with special arm shapes or swollen arms due to certain diseases, traditional fixation methods cannot provide comfortable fixation effects, affecting the patient's surgical experience and recovery process. In addition, traditional assisted adjustable beds are also insufficient in versatility. Due to the lack of flexible arm fixation devices, they cannot adapt to the needs of patients with different body shapes and different conditions, which not only increases the difficulty of surgical preparation, but also affects the smooth progress of the operation. For example, for children or smaller patients, the fixing devices of traditional assisted adjustable beds are too large to effectively fix the patient's arms, posing a safety hazard to the operation.

[0004] Patients often choose to lie on a fixed side of the bed. Over time, one side of the bed is subjected to different pressures, causing the bed to shift. Traditional assisted adjustable beds also have some disadvantages in horizontal monitoring. In terms of accuracy, traditional assisted adjustable beds often lack accurate horizontal monitoring devices, which makes it difficult to accurately grasp the horizontal state of the bed during surgery. Even if the bed is slightly offset, it cannot be discovered in time, thus affecting the accuracy of the surgery. For example, when performing minimally invasive surgery on the limb area, the surgical instruments have extremely high requirements for position accuracy. A slight tilt of the bed will cause deviations in the positioning of the surgical instruments, increasing the risk of the surgery. In terms of response speed, traditional assisted adjustable beds usually cannot respond quickly to changes in the horizontal state of the bed. When the bed is horizontally offset, it takes a period of observation or manual inspection to discover the problem, which will undoubtedly delay the operation. In an emergency, this delay will threaten the patient's life safety.

[0005] Therefore, there is a need to provide an auxiliary adjustment bed for use in high-precision surgery in the limb area, aiming to solve the above problems. Summary of the invention

[0006] In view of the deficiencies in the prior art, the object of the present invention is to provide an auxiliary adjustment bed for use in high-precision surgery in limb areas.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an auxiliary adjustment bed used for high-precision surgery in the limb area, comprising a support block and a bed board, wherein the bed board is arranged on the top of the support block, and fixing components for fixing the patient's arms are arranged on both sides of the bed board, and a level monitoring component for detecting the horizontality of the bed board is arranged on the top of the support block.

[0008] Preferably, the fixing assembly includes an arm placement plate, which is fixedly connected to the outer wall of the bed board, and the top of the inner cavity of the arm placement plate is fixedly connected with two groups of square groove block groups by screws, the interiors of the two groups of square groove block groups are slidably connected with rectangular slide groups, and the bottoms of the two rectangular slide groups are fixedly connected with positioning rods.

[0009] Preferably, the fixing assembly also includes a connecting rod group, the connecting rod group is rotatably connected to the bottom of the positioning rod, the end of the connecting rod group away from the positioning rod is rotatably connected to a double-layer sleeve rod, the inside of the arm placement plate is fixedly connected to an air pump, the output end of the air pump is connected to an air collecting pipe, and the end of the double-layer sleeve rod away from the connecting rod group is slidably connected to the inside of the air collecting pipe.

[0010] Preferably, the fixing assembly also includes a fan-shaped positioning block group, which is fixedly connected to the top of the rectangular slide group, and the interior of the fan-shaped positioning block group is symmetrically rotationally connected to a first clamping block, and the interiors of the two first clamping blocks are symmetrically rotationally connected to a second clamping block.

[0011] Preferably, the horizontal monitoring component includes a square groove, which is opened at the top of the supporting block, a square block is arranged inside the square groove, the top of the square block is slidably connected with four monitoring columns in a rectangular shape, the bottom of the inner cavity of the square block is fixedly connected with a limiting block, a quadrangular prism is arranged inside the limiting block, and four interference balls are arranged on the quadrangular prism and the top of the limiting block.

[0012] Preferably, the horizontal monitoring assembly also includes a first conductive sheet, which is fixedly connected to the bottom of the tetrahedron, a second conductive sheet is fixedly connected to the bottom of the inner cavity of the square block, and a warning light is arranged at the bottom of the support block.

[0013] Preferably, the tops of the two rectangular slide plates are fixedly connected with fan-shaped positioning block groups, and the two fan-shaped positioning block groups are symmetrically arranged, and the fixing assembly has two groups symmetrically arranged with the bed board as the center.

[0014] Preferably, the quadrangular pyramid is slidably connected to the bottom of the inner cavity of the square block, and the four interference balls are arranged below four monitoring columns.

[0015] Preferably, the first conductive sheet is electrically connected to the indicator light, and the second conductive sheet is electrically connected to a power source used by the device.

[0016] The invention provides an auxiliary adjustment bed for high-precision surgery in the limb area. Compared with the prior art, the invention has the following beneficial effects: 1. Through the setting of the fixing assembly, when it is necessary to fix the patient's arms, the double-layer sleeve rod is moved so that the double-layer sleeve rod drives the two rectangular slide groups to move through the connecting rod group and the positioning rod, so that the fan-shaped positioning block group, the first clamping block and the second clamping block fix the patient's arms, and the multi-angle rotation of the first clamping block and the second clamping block can better fit and fix the patient's arms. Compared with the traditional auxiliary adjustment bed for high-precision surgery in the limb area, the traditional auxiliary adjustment bed lacks a fitting double-arm fixing device, or the fixing method is relatively simple and cannot achieve precise positioning, while the multi-angle rotation of the first clamping block and the second clamping block can ensure the firm fixation of the patient's arms, thereby maintaining stability during the operation, providing a guarantee for the precise operation of the operation. At the same time, the traditional fixing method cannot adapt to the arm shapes of different patients, which is easy to cause loose fixation or oppression discomfort, while the clamping block with multi-angle rotation can be adjusted according to the actual situation of the patient, thereby improving the fixation effect and the comfort of the patient.

[0017] 2. By setting up the horizontal monitoring component, when the bed board is offset horizontally, the bed board will generate different pressures on the four monitoring columns. The monitoring columns under excessive pressure will push the four-sided platform to move through the friction ball, so that the first conductive sheet at the bottom of the four-sided platform cannot conflict with the second conductive sheet, and finally the prompt light will go out, thereby reminding the staff that the bed board is offset horizontally. Compared with the traditional auxiliary adjustment bed for high-precision surgery in the limb area, the traditional auxiliary adjustment bed lacks an accurate monitoring mechanism for the horizontal state of the bed board. This design can detect the slight horizontal deviation of the bed board in real time and accurately, providing a more stable operating platform for surgery.

[0018] Secondly, traditional equipment has a delay when detecting horizontal deviation, which makes it impossible for staff to take timely measures. This quick response design allows staff to know the changes in the bed board status in the shortest time possible, make timely adjustments, and reduce surgical risks. The bed board horizontal deviation monitoring design realized by monitoring columns, resistance balls, four-sided tables, first conductive sheets, second conductive sheets and prompt lights has significant advantages in accurate monitoring, quick response and intuitive prompts.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] In the description of the present invention, the terms "center", "lateral", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0036] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0037] Implementation example Figures 1 to 12 As shown, an auxiliary adjustment bed for high-precision surgery in the limb area provided by an embodiment of the present invention includes a support block 11 and a bed board 12. The bed board 12 is arranged on the top of the support block 11. Fixing components for fixing the patient's arms are arranged on both sides of the bed board 12. A level monitoring component for detecting the levelness of the bed board 12 is arranged on the top of the support block 11.

[0038] The fixing component includes an arm placement plate 21, which is fixedly connected to the outer wall of the bed board 12. Two groups of square groove block groups 22 are fixedly connected to the top of the inner cavity of the arm placement plate 21 by screws. The insides of the two groups of square groove block groups 22 are slidably connected with rectangular slide groups 23, and the bottoms of the two rectangular slide groups 23 are fixedly connected with positioning rods 24.

[0039] The fixing assembly also includes a connecting rod group 25, which is rotatably connected to the bottom of the positioning rod 24. The end of the connecting rod group 25 away from the positioning rod 24 is rotatably connected to a double-layer sleeve rod 26. The inside of the arm placement plate 21 is fixedly connected to an air pump 28. The output end of the air pump 28 is connected to an air collecting pipe 27. The end of the double-layer sleeve rod 26 away from the connecting rod group 25 is slidably connected to the inside of the air collecting pipe 27.

[0040] The fixing assembly also includes a fan-shaped positioning block group 29, which is fixedly connected to the top of the rectangular slide group 23. The fan-shaped positioning block group 29 is internally symmetrically rotationally connected to the first clamping block 210, and the two first clamping blocks 210 are internally symmetrically rotationally connected to the second clamping blocks 211.

[0041] The two fan-shaped positioning block groups 29 and their corresponding first clamping blocks 210 and second clamping blocks 211 have different sizes. The fan-shaped positioning block group 29, the first clamping block 210, and the second clamping block 211 on the side away from the support block 11 are larger. Because people's upper arms are thicker than their forearms, the larger fan-shaped positioning block group 29, the first clamping block 210, and the second clamping block 211 can better fit the patient's forearm.

[0042] The tops of the two rectangular slide plates 23 are fixedly connected with fan-shaped positioning block groups 29, and the two fan-shaped positioning block groups 29 are symmetrically arranged so that the two fan-shaped positioning block groups 29 can fit and fix the patient's upper and lower arms at the same time, and two groups of fixing components are symmetrically arranged with the bed board 12 as the center, so that the fixing components can fix the patient's arms.

[0043] The horizontal monitoring component includes a square groove 31, which is opened at the top of the support block 11. A square block 32 is arranged inside the square groove 31. The top of the square block 32 is slidably connected with four monitoring columns 33 in a rectangular shape. The bottom of the inner cavity of the square block 32 is fixedly connected with a limit block 34. A quadrangular platform 35 is arranged inside the limit block 34. Four contact balls 36 are arranged on the top of the quadrangular platform 35 and the limit block 34.

[0044] The level monitoring assembly also includes a first conductive sheet 37 , which is fixedly connected to the bottom of the quadrangular platform 35 , a second conductive sheet 38 is fixedly connected to the bottom of the inner cavity of the square block 32 , and a warning light 39 is provided at the bottom of the support block 11 .

[0045] The quadrangular platform 35 is slidably connected to the bottom of the inner cavity of the square block 32 , and the four abutment balls 36 are arranged below the four monitoring columns 33 , so that the four monitoring columns 33 can push the four abutment balls 36 to move.

[0046] The first conductive sheet 37 is electrically connected to the indicator light 39 , and the second conductive sheet 38 is electrically connected to the power supply of the device, so that when the first conductive sheet 37 and the second conductive sheet 38 collide with each other, the indicator light 39 lights up, otherwise, the indicator light 39 goes out.

[0047] Working principle: In the initial state, the two rectangular slide groups 23 are located on both sides of the square groove block group 22, the four-sided pyramid 35 is located at the center of the limit block 34, the four contact balls 36 are all at the same horizontal height, the four monitoring columns 33 are all at the same horizontal height, and the first conductive sheet 37 is in contact with the second conductive sheet 38.

[0048] During work, before the doctor performs surgery on the patient, the patient often chooses to lie on the fixed side of the bed board 12. Over time, the pressure on one side of the bed board 12 is different, which causes the bed board 12 to shift. During this process, if the bed board 12 shifts horizontally, the bed board 12 will produce different pressures on the four monitoring columns 33 inside the support block 11, and the limit block 34 is fixed to the bottom of the inner cavity of the square block 32, and the four resistance balls 36 are all arranged under the four monitoring columns 33, so that the monitoring column 33 subjected to greater pressure will be transmitted to the four-sided platform 35 through the resistance balls 36, and the resistance balls 36 corresponding to the monitoring column 33 subjected to greater pressure will push the four-sided platform 35 to move.

[0049] When the tetrahedron 35 moves, the first conductive sheet 37 at the bottom will be driven to move, and then the first conductive sheet 37 cannot conflict with the second conductive sheet 38, because there is an electrical connection between the first conductive sheet 37 and the prompt light 39, and there is an electrical connection between the second conductive sheet 38 and the power supply used by the equipment, so when the first conductive sheet 37 conflicts with the second conductive sheet 38, the prompt light 39 lights up, otherwise, the prompt light 39 goes out.

[0050] This can alert the staff of any horizontal deviation of the bed board 12. Compared with traditional auxiliary adjustable beds for high-precision surgery in the limb area, traditional auxiliary adjustable beds lack an accurate monitoring mechanism for the horizontal state of the bed board 12. This design can detect tiny horizontal deviations of the bed board 12 in real time and accurately, providing a more stable operating platform for surgery.

[0051] After the patient lies on the bed board 12, when the doctor needs to perform surgery on the patient's armpit, the patient's arm needs to be fixed to facilitate the doctor's surgical operation. At this time, the staff starts the air pump 28 to inject air into the air collecting pipe 27. Then the air pushes the double-layer rod 26 to slide inside the air collecting pipe 27, and the sliding process of the double-layer rod 26 will push the two connecting rod groups 25 to slide synchronously.

[0052] During the sliding process of the connecting rod group 25, the positioning rod 24 at the bottom of the two rectangular slide groups 23 will be pulled to move, so that the positioning rod 24 will pull the two groups of rectangular slide groups 23 to slide toward the adjacent side along the inside of the square groove block group 22, and the tops of the two rectangular slide groups 23 are fixedly connected with the fan-shaped positioning block group 29, so that the two groups of rectangular slide groups 23 drive the two fan-shaped positioning block groups 29 on the top to resist the patient's upper arms, and then the second clamping block 211 will first resist the patient's upper arms, and the second clamping block 211 will fit according to the shape of the patient's upper arms, and then the second clamping block 211 will rotate along the inside of the first clamping block 210, and the second clamping block 211 will rotate along the inside of the fan-shaped positioning block group 29, so as to better fit and fix the patient's arms.

[0053] At the same time, the two fan-shaped positioning block groups 29 and their corresponding first clamping blocks 210 and second clamping blocks 211 have different sizes. The fan-shaped positioning block group 29, the first clamping block 210, and the second clamping block 211 on the side away from the support block 11 are larger. Because people's upper arms are thicker than their forearms, the larger fan-shaped positioning block group 29, the first clamping block 210, and the second clamping block 211 can better fit the patient's forearms, so that the two fan-shaped positioning block groups 29 can fit and fix the patient's upper and lower arms at the same time.

[0054] In addition, two groups of fixing components are symmetrically arranged with the bed board 12 as the center, so that the fixing components can fix the patient's arms, and the multi-angle rotation of the first clamping block 210 and the second clamping block 211 can better fit and fix the patient's arms. Compared with the traditional auxiliary adjustment bed for high-precision surgery in the limb area, the traditional auxiliary adjustment bed lacks a fitting arm fixing device, or the fixing method is relatively simple and cannot achieve precise positioning. The multi-angle rotation of the first clamping block 210 and the second clamping block 211 can ensure the firm fixation of the patient's arms, and then maintain stability during the operation, providing a guarantee for the precise operation of the operation. At the same time, the traditional fixing method cannot adapt to the arm shape of different patients, which is easy to cause loose fixation or compression discomfort, and the multi-angle rotating clamping block can be adjusted according to the actual situation of the patient, thereby improving the fixation effect and the patient's comfort.

[0055] Finally, when the staff needs to fix the patient's arms, they can use the air pump 28 to extract the air inside the air collecting pipe 27, and then the air drives the double-layer sleeve rod 26 to slide in the opposite direction inside the air collecting pipe 27. During the reverse sliding process of the double-layer sleeve rod 26, the two connecting rod groups 25 will be pushed to reset synchronously. Finally, the two connecting rod groups 25 push the two rectangular slide groups 23 to slide toward the two ends of the square groove block group 22 through the positioning rod 24, so that the two rectangular slide groups 23 drive the fan-shaped positioning block group 29, the first clamping block 210, and the second clamping block 211 to reset, thereby achieving the fixation effect on the patient's arms.
