Description

Technical Field

[0001] This invention belongs to the field of nephrology puncture technology, specifically relating to nephrology puncture auxiliary devices. Background Technology

[0002] Nephrology biopsy is mainly used to determine the pathological type and cause of kidney diseases, such as nephrotic syndrome, acute and chronic nephritis, and unexplained kidney function impairment. By obtaining a kidney tissue sample, combined with pathological, immunological, or genetic testing, it helps to develop a precise treatment plan. During the sampling, the patient is usually in a prone position with a pillow about 10 cm high placed under the abdomen to push the kidney towards the back to facilitate the puncture.

[0003] However, in actual use, due to the different sizes of patients, the required height of the pillow also varies. A single height pillow cannot meet the needs of different people, making it less suitable for actual use. Although multiple pillows of different heights can be placed in the operating room, this requires a special cabinet for storage, which undoubtedly affects the overall spatial layout of the operating room.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0034] Reference Figure 1 - Figure 8 This is the first embodiment of the present invention, which provides a nephrology puncture assistance device that elevates the patient's abdomen, protruding the kidney for easier puncture. It includes a lifting mechanism and a bed 10 with an installation port 11. A support plate 12 for elevating the patient's abdomen is located within the installation port 11. A support seat 13 is located on the outer side of the support plate 12. A gap is provided between the lower end of the support plate 12 and the support seat 13 to prevent jamming when the support plate 12 rotates. A mounting box 14 is fixedly connected to the lower end of the bed 10. The mounting box 14 is equipped with a lifting assembly 15 and a stabilizing assembly 16 for lifting the support plate 12; a switching mechanism, which includes a mounting cavity 20 located at the left end of the bearing seat 13, with round openings on the inner wall of the mounting cavity 20, and a rotating shaft 21 fixedly connected to both ends of the support plate 12 and rotatably connected to the bearing seat 13, with a sinking groove 22 at the lower end of the support plate 12, the rotating shaft 21 rotating to drive the support plate 12 to flip, and a transmission assembly 23 providing power for the rotation of the support plate 12 on the rotating shaft 21, and a pushing assembly 24 providing power for the rotation of the support plate 12 inside the mounting box 14;

[0035] The changing mechanism includes a stop plate 30 disposed in the mounting box 14, a lifting plate 31 that cooperates with the stop plate 30 is slidably connected in the mounting box 14, a deformation component 32 that switches the shape of the support plate 12 is provided on the lifting plate 31, a T-shaped groove 33 is provided in the lifting plate 31, a T-shaped plate 34 is slidably connected in the T-shaped groove 33, the T-shaped plate 34 is elastically connected to the inner wall of the T-shaped groove 33 by a first spring 35, a pumping component 36 that provides an air source for the deformation component 32 is provided in the T-shaped groove 33, and an anti-reset component 37 is provided in both the T-shaped groove 33 and the mounting cavity 20.

[0036] The mounting box 14 has ventilation holes on its outer side to facilitate heat dissipation of the electrical components inside. The mounting box 14 has a door on its back to allow for maintenance of the electrical components and replacement of parts. The pivot 21 is located in the middle of the support plate 12, so that the upper position of the support plate 12 will not change in the vertical direction after the support plate 12 is rotated. The length or width of the support plate 12 can be adjusted as needed, depending on different requirements, and is not limited here.

[0037] Furthermore, the lifting assembly 15 includes a bracket 151 fixedly connected to the mounting box 14, a motor 152 fixedly connected to the bracket 151, a threaded rod 153 fixedly connected to the output shaft of the motor 152, a bearing port on the lifting plate 31, and a threaded sleeve 154 that mates with the threaded rod 153 fixedly connected inside the bearing port; the stabilizing assembly 16 includes a pair of symmetrically arranged inclined plates 161 fixedly connected to the lifting plate 31, the upper ends of the two inclined plates 161 fixedly connected to the bearing seat 13, the two inclined plates 161 and the lifting plate 31 forming a triangular structure, the two inclined plates 161 having a strip-shaped opening 162, and a reinforcing strip 163 inside the strip-shaped opening 162.

[0038] It should be noted that the motor 152 here can be wirelessly controlled by an external remote control. When in use, simply press the raise and lower buttons on the remote control to raise and lower the lifting plate 31. The support plate 12 is raised and lowered through transmission. The wireless control here is existing technology and will not be described in detail here. The threads can be set to be denser, so that the raising and lowering adjustment of the threaded sleeve 154 is more precise with each rotation of the motor 152. At the same time, the speed of the motor 152 is low, so the overall adjustment is more stable. The low speed of the motor 152 here is existing technology and will not be described in detail here.

[0039] In use, initially, the upper surface of the support plate 12 is flush with the upper surface of the bed 10. When a puncture is required, the patient lies face down on the bed 10 with their abdomen resting on the support plate 12. The upper and lower side walls of the support plate 12 are also padded to prevent discomfort for the patient. When a puncture is needed, the motor 152 is rotated, and the output shaft of the motor 152 rotates, causing the lifting plate 31 to move upward, which in turn causes the inclined plate 161 to move upward, thereby causing the support seat 13 to move upward, which in turn causes the rotating shaft 21 to move upward, which in turn causes the support plate 12 to move upward, lifting the patient's abdomen and making the back protrude, facilitating the puncture for kidney sampling. It is worth noting that the two inclined plates 161 and the lifting plate 31 form a triangular structure, making the support seat 13 more stable. At the same time, the reinforcing strip 163 acts as a reinforcing rib, further increasing the overall stability. The way the threaded rod 153 lifts the support seat 13 and drives the support plate 12 allows for a wider range of adjustment and eliminates the need for multiple pillows.

[0040] In summary, by setting up a lifting mechanism, when it is necessary to lift the patient's abdomen, simply start the motor 152 to drive the support plate 12 to rise through the transmission, thus lifting the patient's abdomen. The lifting distance can be controlled, and there is no need to use a special pillow. This saves time and also solves the problem of needing multiple pillows when lifting to different heights. Example 2

[0041] Reference Figure 1 - Figure 9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a switching mechanism for a nephrology puncture assist device, solving the problem of adapting it to different obese patients. It includes a transmission assembly 23, comprising a T-shaped opening 231 disposed on a support base 13. A left-end rotating shaft 21 extends through the round opening into the mounting cavity 20 and is fixedly connected to a gear 232. A T-shaped toothed plate 233, meshing with the gear 232, is slidably connected within the T-shaped opening 231. The lower end of 33 is provided with a cut edge 234, and the toothed plate 233 is elastically connected to the inner wall of the T-shaped opening 231 through the second spring 235; the pushing component 24 includes a vertical groove 241 provided in the mounting box 14, an inclined groove 242 is provided on the vertical groove 241, a cylinder 243 slides in the vertical groove 241, a wedge block 244 that cooperates with the cut edge 234 is fixedly connected to the reinforcing strip 163, the left end of the reinforcing strip 163 extends to the front side of the vertical groove 241, and the cylinder 243 is fixedly connected to the reinforcing strip 163.

[0042] Specifically, the setting of the tangent 234 here avoids the phenomenon of jamming between the wedge block 244 and the toothed plate 233. The horizontal projection length of the inclined groove 242 is sufficient to ensure that the toothed plate 233 can be pushed upward. It is worth noting that the upward distance of the toothed plate 233 drives the gear 232 to rotate 180°, thereby causing the rotating shaft 21 to rotate 180°, ensuring that the support plate 12 can be completely changed.

[0043] Before puncture, determine which side of the support plate 12 needs to be supported based on the patient's body shape. The side with the recessed groove 22 is suitable for obese patients. It should be explained that, since obese patients have protruding abdomens, if the support plate 12 is still set as a flat surface, it will only compress the protruding abdomen of the patient at first and will not be able to lift the patient. As a result, the patient's abdomen will be compressed, which will affect the patient's breathing and cause the patient's discomfort. However, after setting the recessed groove 22, it can leave space for the protruding abdomen when the patient's abdomen is lifted, so as not to hinder the patient's breathing.

[0044] When it is necessary to change the shape of the upper surface of the support plate 12, the lifting plate 31 moves upward, thereby driving the inclined plate 161 upward, the reinforcing plate upward, and the cylinder 243 upward. At this time, the cylinder 243 slides within the vertical groove 241. It is worth noting that when the cylinder 243 slides within the vertical groove 241, the distance the support plate 12 rises is the maximum height it can support. When the cylinder 243 slides within the inclined groove 242, the support plate 12 does not support the patient. The vertical groove 241 can be set to different lengths as needed to ensure that the support plate 12 rises to a sufficient height. Before the patient is on the bed, the cylinder 243 moves to the connection point between the vertical groove 241 and the inclined groove 242, and then the lifting plate 31 continues to move upward. At this time, the cylinder 243 continues to move upward through the transmission, and moves into the inclined groove 242. When it moves into the inclined groove 242, the cylinder 243 moves upward and towards the threaded rod 153. During this process, it will drive the wedge block 244 to move towards the toothed plate 233. When the inclined edge of the wedge block 244 abuts against the tangent edge 234 of the toothed plate 233, the wedge block 244 continues to move and pushes the toothed plate 233 upward. When the toothed plate 233 moves upward, since the toothed plate 233 is T-shaped, the transverse edge of the toothed plate 233 slides in the T-shaped opening 231 for guidance. The movement of the toothed plate 233 drives the gear 232 to rotate, which in turn causes the rotating shaft 21 to rotate, causing the support plate 12 to flip, so as to be suitable for people with different obesity.

[0045] In summary, by setting up a switching mechanism, after the lifting plate 31 rises and drives the cylinder 243 to move into the inclined groove 242, it can also drive the support plate 12 to flip, thereby making the sinking groove 22 rise, so as to be suitable for people of different body types. Example 3

[0046] Reference Figure 1 - Figure 9 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a changing mechanism for the puncture assistance device for nephrology, solving the problem of how to further change the shape of the support plate 12 to suit more people. It includes a deformation component 32, which includes an air storage chamber 321 disposed in the support plate 12. The support plate 12 is provided with a support groove 322, and an arc-shaped airbag 323 is fixedly connected in the support groove 322. The arc-shaped airbag 323 is sealed and connected to the air storage chamber 321 through a connecting pipe 324. The air pumping component 36 includes a telescopic airbag 361 fixedly connected to the T-shaped plate 34. The lifting plate 31 and the support seat 13 are both provided with receiving ports. The telescopic airbag 361 is provided with a guide pipe 362, which passes through the receiving port and extends into the air storage chamber 321. The center of the rotating shaft 21 and the gear 232 is provided with a horizontal opening extending into the air storage chamber 321. A sealed bearing 363 is rotatably connected in the horizontal opening. The inner ring of the sealed bearing 363 is fixedly connected to the guide pipe 362.

[0047] Specifically, the amount of gas in the telescopic airbag 361 is sufficient to inflate the arc-shaped airbag 323. At the same time, lines can be set on the arc-shaped airbag 323 so that it can automatically retract after deflation. The air guide tube 362 enters from the center of the rotating shaft 21, which can prevent the air guide tube 362 from getting stuck or tangled with the rotating shaft 21 during the rotation of the rotating shaft 21.

[0048] The anti-reset assembly 37 includes a first guide groove 371, a second guide groove 372, a third guide groove 373, a fourth guide groove 374, and a fifth guide groove 375, which are connected end-to-end within the T-shaped groove 33 and the mounting cavity 20. Both the toothed plate 233 and the T-shaped plate 34 are provided with inner grooves 376. A movable block 377 is slidably connected within the inner groove 376. The movable block 377 is elastically connected to the inner wall of the inner groove 376 via a third spring. A lever 378 is fixedly connected to the movable block 377. The lever 378 is connected to the first guide groove 371, the second guide groove 372, the third guide groove 373, the fourth guide groove 374, and the fifth guide groove 375. The groove 372, the third guide groove 373, the fourth guide groove 374, and the fifth guide groove 375 cooperate; the first guide groove 371, the second guide groove 372, the third guide groove 373, the fourth guide groove 374, and the fifth guide groove 375 are all inclined grooves 242. A concave point is formed between the third guide groove 373 and the fourth guide groove 374. The slope of the third guide groove 373 is greater than the slope of the fourth guide groove 374. A guide block 379 is provided on the upper side of the concave point. The guide block 379 is inclined, and the right sidewall of the guide block 379 is located on the upper left side of the concave point.

[0049] It should be noted that a concave point is formed between the third guide groove 373 and the fourth guide groove 374. When the lever 378 is at the concave point, it can prevent the lever 378 from automatically resetting, thereby preventing the automatic resetting of the toothed plate 233 or the T-shaped plate 34, ensuring the stability of the support plate 12 or maintaining the stability of the arc-shaped airbag 323 during deployment. Here, the guide block 379 is set at an angle, and the right side wall of the guide block 379 is located on the upper left side of the concave point. Thus, when the lever 378 moves upward at the concave point, it moves from the concave point into the fourth guide groove 374, instead of returning to the third guide groove 373. It is worth noting that when the patient's abdomen is lifted or lowered, there is a gap between the lifting plate 31 and the stop plate 30. At this time, the T-shaped plate 34 will not squeeze the telescopic airbag 361 at the beginning.

[0050] In use, when the lifting plate 31 moves upward, the gear plate 233 moves upward, driving the moving block 377 to move upward, which in turn drives the lever 378 to move upward. This causes the lever 378 to move from the connection point between the first guide groove 371 and the fifth guide groove 375 into the first guide groove 371, then guided by the second guide groove 372 to the connection point between the second guide groove 372 and the third guide groove 373. At this point, the lifting plate 31 reaches its highest point. Then, the motor 152 reverses, causing the threaded rod 153 to reverse as well. Through the threaded sleeve 154, the lifting plate 31 descends. At this point, the lever 378 moves from the connection point between the second guide groove 372 and the third guide groove 373 into the third guide groove 373, and finally to the concave point formed by the third guide groove 373 and the fourth guide groove 374. The gear plate 233 continuously rotates, driving the gear 232. As the lever 378 moves... When the lever 232 moves to the connection between the second guide groove 372 and the third guide groove 373, the gear 232 rotates more than 180°. When the lever 378 returns to the concave point, the gear 232 rotates 180°. At this time, since the lever 378 is against the concave point, it cannot continue to move downward. Even if the wedge block 244 separates from the toothed plate 233, the toothed plate 233 will not descend, ensuring that the gear 232 rotates 180°, thereby ensuring the stability of the rotation of the support plate 12. When the support plate 12 needs to be changed again, the lever 378 is pushed upward again. Under the action of the guide block 379, the lever 378 moves into the fourth guide groove 374 and finally resets through the fifth guide groove 375. The movement of the T-shaped plate 34 is the same. When pressed for the first time, it can ensure the compressed state of the telescopic airbag 361. When the T-shaped plate 34 is pressed for the second time, it can reset the telescopic airbag 361.

[0051] When the non-sunken surface of the support plate 12 is facing upwards (i.e., the surface opposite to the sinker surface is facing upwards), and the middle of the support plate 12 needs to bulge slightly, it is suitable for people with a thinner build and a concave abdomen. For individuals with concave abdomens, when the abdomen is lifted, only the two ends of the abdomen are initially subjected to force, resulting in a small force-bearing area and causing discomfort to the patient. Therefore, it is necessary to increase the force-bearing area. At this time, the motor 152 simply reverses, causing the lifting plate 31 to move downwards, which in turn moves the T-shaped plate 34 downwards. During this process, because the stop plate 30 is fixed, the downward movement of the T-shaped plate 34 reduces the distance between the top of the T-shaped groove 33 and the upper surface of the T-shaped plate 34, thereby compressing the telescopic airbag 361. This causes the gas in the telescopic airbag 361 to be pumped into the air storage chamber 321, and then pumped into the arc-shaped airbag 323 after being guided through the connecting pipe 324, causing the arc-shaped airbag 323 to inflate, thus adapting to individuals with concave abdomens. When the lifting plate 31 rises, the same applies to the upper toothed plate 233. At this time, the T-shaped plate 34 will not return to its original position until it is pressed again, ensuring the stability of the arc-shaped airbag 323's inflation.

[0052] In summary, by setting up a change mechanism, the shape of the support plate 12 can be further changed to accommodate patients with different degrees of obesity. Furthermore, by setting up an anti-reset component 37, the automatic resetting of the toothed plate 233 and the T-shaped plate 34 can be prevented, thus ensuring the stability of the support plate 12 or the stability of the arc-shaped airbag 323.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
