Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an isolated kidney fascia suspension fixation device and a use method thereof. Background Art

[0002] With the continuous deepening of medical research and the continuous development of clinical technology, the research and treatment of isolated kidneys have become crucial in many fields. In the optimization of kidney transplantation technology, the pathological research of kidney diseases and the exploration of new treatment methods, precise operation and observation of isolated kidneys are required. At present, although the existing isolated kidney fascia suspension device can fix and support the isolated kidney to a certain extent, it has obvious deficiencies in simulating the pressure exerted on the kidney in the human body.

[0003] The human kidney is in a complex physiological environment in the body and is surrounded by a variety of tissues, such as fascia, fat, muscle, etc. These tissues work together to exert a specific pressure on the kidney. This pressure plays a key role in maintaining the normal shape, position, internal blood circulation and metabolic function of the kidney. Under normal physiological conditions, the pressure on the kidney is dynamically balanced and can adapt to different physiological activities and external changes. However, existing isolated kidney fascia suspension devices often only focus on mechanical fixation of the kidney, but ignore the simulation of pressure. These devices usually use simple clamps or hooks to suspend the kidney, which cannot provide a pressure environment similar to that inside the human body. This leads to the pressure conditions of the kidney being far from the actual situation in the human body when using these devices for experiments or research. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an ex vivo kidney fascia suspension fixation device and a method of using the same, which solves the problem that the device usually uses a simple clamp or hook to suspend the kidney and cannot provide a pressure environment similar to that inside the human body.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an isolated kidney fascia suspension and fixation device, comprising a cold storage box, both sides of the inner wall of the cold storage box are provided with support belts, the inner part of the support belts is slidably connected with a plurality of sliding shafts, the plurality of sliding shafts are connected by support ropes, the plurality of support ropes form a support net, and one side of the outer wall of the sliding shaft is fixedly connected with a sliding mechanism;

[0006] A tightening belt is arranged on one side of the inner wall of the cold storage box, and the tightening belt is connected to the airbag through a connecting rod. The two airbags are connected through a transverse tube, and a circulation mechanism is arranged inside the transverse tube. A condensation component is connected to one side of the outer wall of the airbag.

[0007] Preferably, the circulation mechanism includes a rotating rod, which is rotatably connected to the inside of the transverse tube, one end of the rotating rod is fixedly connected to a wind plate and a mainspring in sequence, the outer wall of the mainspring is fixedly connected to a fixing ring, the fixing ring is connected to the inner wall of the transverse tube through a positioning rod, the inside of the transverse tube is slidably connected to a choke tube, the rotating rod passes through the choke tube, a ventilation duct is opened inside the choke tube, both ends of the ventilation duct are respectively connected to a slide, one end of a spring is fixedly connected to the inner wall of the slide, the other end of the spring is fixedly connected to one end of a choke rod, the other end of the choke rod is connected to the ventilation plate through an extension rod, the choke rod is slidably connected to the inside of the slide, and the ventilation plate is slidably connected to the inside of the transverse tube.

[0008] Preferably, the sliding mechanism includes a half ring, which is fixedly connected to one side of the outer wall of the sliding shaft, and the other end of the tightening belt passes through multiple half rings in sequence and is fixedly connected to the outermost sliding shaft. One end of a coil spring is provided on one side of the inner wall of the cold storage box, and the other end of the coil spring is fixedly connected to the innermost sliding shaft, and the tightening belt passes through the coil spring.

[0009] Preferably, the condensation assembly includes an air pump, which is fixedly connected to one side of the outer wall of the cold storage box, the input end of the air pump is connected to the condensation box fixed to the outer wall of the cold storage box, and the output end of the air pump is connected to the air bag through a hose.

[0010] Preferably, an outer wall of the support rope is fixedly connected with an oblique strip.

[0011] Preferably, a swivel one is rotatably connected to one side of the inner wall of the cold storage box, one end of the tightening belt is fixedly connected to the swivel one, a swivel two is rotatably connected to the inner wall of the cold storage box, and both ends of the support belt are fixedly connected to the swivel two.

[0012] Preferably, the outer wall of the sliding shaft is rotatably connected with a slip ring, and the slip ring is slidably connected to the inside of the supporting belt.

[0013] Preferably, a baffle is fixedly connected to the interior of the transverse tube, and the rotating rod passes through the baffle.

[0014] Preferably, a sealing cover is threadedly connected to the top of the cold storage box, and handles are fixedly connected to both ends of the top of the cold storage box.

[0015] In addition, the present invention also provides a method for using an isolated kidney fascia suspension fixation device, comprising the following steps:

[0016] S1. Rotating the sealing cover can change the closed state of the cold storage box. When the sealing cover is unscrewed, the cold storage box is in an open state, and the isolated kidney can be placed or taken out;

[0017] S2. Place the ex vivo kidney on the top of the support belt. The gravity of the kidney causes the support belt to fall. Under the limit of the tightening belt, the innermost sliding axis slides outward from the support belt to increase the distance between the support nets on both sides.

[0018] S3, the air pump input end is connected to the condenser box on the outer wall of the cold storage box, the condenser box cools the gas to a low temperature, and when the air pump is working, the low-temperature gas is extracted from the condenser box;

[0019] S4. The air pump delivers low-temperature gas to one side of the airbag, causing the airbag to expand and become larger. The outer wall of the airbag squeezes the kidney to produce simulated pressure, helping the kidney maintain its normal shape and structure. At the same time, part of the gas flows to the transverse tube;

[0020] S5. The gas flowing from the ventilation plate to one side of the choke tube generates wind pressure on the choke tube, pushing the choke tube to slide toward the airbag on the other side. After being blocked by the baffle, the wind pressure is concentrated to the center of the slideway, pushing the choke rod to slide so that the slideway is connected to the ventilation duct. The low-temperature gas enters the airbag on the other side, causing the airbag on that side to expand and become larger, generating simulated pressure on the kidneys.

[0021] S6. The wind-blocking rod slides to contract the spring, and the low-temperature gas flows and pushes the wind plate to rotate, driving the spring to twist. When the initial gas in one side of the airbag is not enough to push the spring to contract, the spring returns to its original state and pushes the wind-blocking rod to block the ventilation duct and the slideway. The spring also returns to its original state and rotates in the opposite direction, causing the wind plate to rotate in the opposite direction.

[0022] S7. The wind plate rotates in the opposite direction to fan the gas inside the airbag on the other side to circulate in the opposite direction. Similarly, the gas in the airbag on the other side flows back into the initial airbag. The airbags on both sides expand and contract in turn, simulating pressure on the kidneys and forming a dynamic pressure balance, ensuring that the kidneys are always subjected to uniform pressure and maintaining their normal morphological structure.

[0023] The present invention provides an isolated kidney fascia suspension fixation device and a method of using the same.

[0024] Beneficial effects:

[0025] 1. The present invention forms a dynamic pressure balance for the kidneys by using the special gas circulation mechanism to expand and contract the air bags on both sides in sequence. No matter how the shape and size of the kidneys change, the pressure can be automatically adjusted according to the actual situation to ensure that the kidneys are always under uniform pressure. Dynamic pressure balance is essential to maintain the normal morphological structure of the kidneys, avoiding deformation, damage or dysfunction of the kidneys due to excessive or insufficient local pressure, and providing a stable pressure environment for the study and treatment of the kidneys.

[0026] 2. The present invention can adapt to different sizes of ex vivo kidneys through the design of the support belt and the sliding shaft. The support belt falls under the gravity of the kidney, and the sliding shaft slides to adjust the spacing of the support net to avoid blocking the renal vein and renal artery. At the same time, the oblique strips increase the contact area between the support net and the kidney to prevent damage to the kidney surface due to too thin support.

[0027] 3. The air pump of the present invention cooperates with the condensation box to provide low-temperature gas for the air bag. The low-temperature environment helps to reduce the metabolic rate of the kidneys and reduce energy consumption, thereby extending the storage time of the kidneys and maintaining their activity.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example:

[0039] Please refer to the attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides an in vitro kidney fascia suspension and fixation device, comprising a cold storage box 1, support belts 2 are arranged on both sides of the inner wall of the cold storage box 1, a plurality of sliding shafts 3 are slidably connected inside the support belts 2, the plurality of sliding shafts 3 are connected by support ropes 4, the plurality of support ropes 4 form a support net, and a sliding mechanism 5 is fixedly connected to one side of the outer wall of the sliding shaft 3;

[0040] A tightening belt 6 is provided on one side of the inner wall of the cold storage box 1, and the tightening belt 6 is connected to the airbag 8 through a connecting rod 7. The two airbags 8 are connected through a transverse tube 9, and a circulation mechanism is provided inside the transverse tube 9. A condensation component is connected to one side of the outer wall of the airbag 8;

[0041] Specifically, the ex vivo kidney is stored in the cold storage box 1, the support belt 2 supports the ex vivo kidney as a whole, the support net formed by multiple support ropes 4 supports the bottom and side fascia of the ex vivo kidney, and the air pump 27 transmits gas to the inside of the air bag 8 to expand it, and simulates pressure on the surface of the ex vivo kidney. The transmitted gas is repeatedly transmitted in the transverse tube 9 through the circulation mechanism, so that the air bags 8 on both sides form a dynamic pressure balance on the ex vivo kidney, helping the kidney to maintain its normal morphological structure.

[0042] The circulation mechanism includes a rotating rod 12, which is rotatably connected to the inside of the transverse tube 9, one end of the rotating rod 12 is fixedly connected to a wind plate 13 and a spring 14 in sequence, the outer wall of the spring 14 is fixedly connected to a fixing ring 15, the fixing ring 15 is connected to the inner wall of the transverse tube 9 through a positioning rod 16, the inside of the transverse tube 9 is slidably connected to a choke tube 17, the rotating rod 12 passes through the choke tube 17, a ventilation duct 18 is provided inside the choke tube 17, both ends of the ventilation duct 18 are respectively connected to slideways 19, one end of a spring 20 is fixedly connected to one side of the inner wall of the slideway 19, the other end of the spring 20 is fixedly connected to one end of a choke rod 21, the other end of the choke rod 21 is connected to a ventilation plate 23 through an extension rod 22, the choke rod 21 is slidably connected to the inside of the slideway 19, and the ventilation plate 23 is slidably connected to the inside of the transverse tube 9;

[0043] A baffle 33 is fixedly connected inside the transverse tube 9, and the rotating rod 12 passes through the baffle 33;

[0044] Specifically, the air pump 27 draws low-temperature initial gas from the inside of the condensation box 28 into the inside of the airbag 8 on one side, so that the airbag 8 on one side expands and becomes larger. The outer wall of the airbag 8 squeezes the isolated kidney to generate simulated pressure, helping the kidney to maintain its normal morphological structure. While this part of the initial low-temperature gas slowly fills the airbag 8 on one side, part of the gas flows to the cross tube 9, and flows from the inside of the ventilation plate 23 to one side of the choke tube 17, generating wind pressure on the choke tube 17, pushing the choke tube 17 to slide toward the direction of the airbag 8 on the other side until the choke tube 17 is blocked by the baffle 33 on one side. At this time, the choke tube 17 cannot continue to move, and the wind pressure generated by the gas is concentrated to the center of the slide 19. Driven by the wind pressure, the choke rod 21 slides toward the inside of the slide 19, connecting the slide 19 with the ventilation duct 18, and the low-temperature gas enters the airbag 8 on the other side. The sac 8 expands and becomes larger, squeezing the isolated kidney to produce simulated pressure, and the choke rod 21 slides while the spring 20 contracts. When the low-temperature gas flows from the airbag 8 on one side to the airbag 8 on the other side, it pushes the wind plate 13 to rotate and drives the spring 14 to twist. When the initial gas inside the airbag 8 on one side is no longer sufficient to push the spring 20 to contract, the spring 20 returns to its original state, pushing the choke rod 21 to block the ventilation duct 18 and the slide 19 again. At the same time, the spring 14 also returns to its original state and starts to rotate in the opposite direction. The wind plate 13 rotates in the opposite direction, fanning the gas inside the airbag 8 on the other side to circulate in the opposite direction. Similarly, the gas in the airbag 8 on the other side flows back into the initial airbag 8. In this reciprocating cycle, the airbags 8 on both sides expand and contract in turn, completing the simulated pressure on the isolated kidney inside the cold storage box 1, so that the airbags 8 on both sides can form a dynamic pressure balance for the isolated kidney. No matter how the shape and size of the kidneys change, the air bags 8 on both sides can automatically adjust the pressure according to the actual situation to ensure that the kidneys are always subjected to uniform pressure. This dynamic pressure balance is essential for maintaining the normal morphological structure of the kidneys. It can prevent the kidneys from being deformed, damaged or having dysfunction due to excessive or insufficient local pressure.

[0045] The sliding mechanism 5 includes a half ring 24, which is fixedly connected to one side of the outer wall of the sliding shaft 3. The other end of the tightening belt 6 passes through a plurality of half rings 24 in sequence and is fixedly connected to the outermost sliding shaft 3. One end of a coil spring 26 is provided on one side of the inner wall of the cold storage box 1. The other end of the coil spring 26 is fixedly connected to the innermost sliding shaft 3. The tightening belt 6 passes through the coil spring 26.

[0046] The outer wall of the sliding shaft 3 is rotatably connected with a slip ring 32, and the slip ring 32 is slidably connected to the inside of the supporting belt 2;

[0047] The outer wall of the support rope 4 is fixedly connected with an oblique strip 30;

[0048] Specifically, the ex vivo kidney is placed on the top of the support belt 2, and the support belt 2 falls due to gravity. The more the support belt 2 falls, the more the innermost sliding shaft 3 slides toward the outside of the support belt 2 under the limitation of the tightening belt 6, so that the distance between the two innermost sliding shafts 3 of the support belt 2 increases, and the distance between the support nets on both sides also increases, so that the support belt 2 can adapt to supporting ex vivo kidneys of different sizes and avoid the innermost sliding shafts 3 on both sides from blocking the renal vein and renal artery of the ex vivo kidney. While the sliding shaft 3 slides, the slip ring 32 converts its sliding motion into its own rolling motion, which reduces the generation of friction and makes the sliding of the sliding shaft 3 smoother. The oblique bar 30 increases the contact area between the support net and the ex vivo kidney to avoid damage to the kidney surface caused by the support net being too thin.

[0049] The condensation assembly includes an air pump 27, which is fixedly connected to one side of the outer wall of the cold storage box 1, the input end of the air pump 27 is connected to a condensation box 28 fixed to the outer wall of the cold storage box 1, and the output end of the air pump 27 is connected to the air bag 8 through a hose 29;

[0050] Specifically, the input end of the air pump 27 is connected to the condensation box 28 fixed on the outer wall of the cold storage box 1. The condensation box 28 is usually made of a material with good thermal insulation and sealing properties, and can effectively maintain the internal low temperature state. Inside the condensation box 28, the gas is cooled to the required low temperature through the refrigerant circulation technology. When the air pump 27 is working, the gas extracted from the condensation box 28 is already at a lower temperature. The output end of the air pump 27 is connected to the air bag 8 through the hose 29. The hose 29 has certain flexibility and elasticity and can adapt to different installation positions and angles to ensure that the gas can be smoothly transmitted from the air pump 27 to the air bag 8. When the low-temperature gas enters the air bag 8 through the hose 29, the air bag 8 can not only simulate pressure on the surface of the isolated kidney, but also provide a relatively cool environment for the kidney through the action of the low-temperature gas. This low-temperature environment helps to reduce the metabolic rate of the kidney and reduce energy consumption, thereby prolonging the storage time of the kidney and maintaining its activity. At the same time, low temperature can also inhibit the growth and reproduction of bacteria and reduce the risk of kidney contamination.

[0051] One side of the inner wall of the cold storage box 1 is rotatably connected with a swivel 1 25, one end of the tightening belt 6 is fixedly connected to the swivel 1 25, the inner wall of the cold storage box 1 is rotatably connected with a swivel 2 31, and both ends of the support belt 2 are fixedly connected to the swivel 2 31;

[0052] A sealing cover 10 is threadedly connected to the top of the cold storage box 1, and handles 11 are fixedly connected to both ends of the top of the cold storage box 1;

[0053] Specifically, rotating the sealing cover 10 can change the closed state of the cold storage box 1, so that the isolated kidney can be placed in or taken out of the cold storage box 1, and rotating the handle 11 can drive the rotating ring 25 to rotate, so that the isolated kidney suspended and fixed inside the cold storage box 1 can rotate at the same time, so that the isolated kidney inside the cold storage box 1 can be observed from all directions.

[0054] In addition, the present invention also provides a method for using an isolated kidney fascia suspension fixation device, comprising the following steps:

[0055] S1. Rotating the sealing cover 10 can change the closed state of the cold storage box 1. When the sealing cover 10 is unscrewed, the cold storage box 1 is in an open state, and the isolated kidney can be placed or taken out;

[0056] S2, placing the ex vivo kidney on the top of the support belt 2, the gravity of the kidney causes the support belt 2 to fall, and under the limit of the tightening belt 6, the innermost sliding shaft 3 slides toward the outside of the support belt 2 to increase the distance between the support nets on both sides;

[0057] S3, the input end of the air pump 27 is connected to the condenser box 28 on the outer wall of the cold storage box 1, and the condenser box 28 cools the gas to a low temperature. When the air pump 27 is working, the low-temperature gas is extracted from the condenser box 28;

[0058] S4, the air pump 27 delivers low-temperature gas to one side of the airbag 8, so that the airbag 8 expands and becomes larger. The outer wall of the airbag 8 squeezes the kidney to produce simulated pressure, helping the kidney to maintain a normal shape and structure. At the same time, part of the gas flows to the transverse tube 9;

[0059] S5. The gas flowing from the ventilation plate 23 to one side of the choke tube 17 generates wind pressure on the choke tube 17, pushing the choke tube 17 to slide toward the airbag 8 on the other side. After being blocked by the baffle 33, the wind pressure is concentrated to the center of the slideway 19, pushing the choke rod 21 to slide so that the slideway 19 is connected with the ventilation duct 18. The low-temperature gas enters the airbag 8 on the other side, causing the airbag 8 on that side to expand and become larger, generating simulated pressure on the kidneys.

[0060] S6, the wind blocking rod 21 slides to make the spring 20 contract, and the low-temperature gas flows and pushes the wind plate 13 to rotate and drive the spring 14 to twist. When the initial gas in the airbag 8 on one side is not enough to push the spring 20 to contract, the spring 20 returns to its original state and pushes the wind blocking rod 21 to block the ventilation duct 18 and the slideway 19. The spring 14 also returns to its original state and rotates in the reverse direction to make the wind plate 13 rotate in the reverse direction.

[0061] S7, the wind plate 13 rotates in the opposite direction to fan the gas inside the airbag 8 on the other side to circulate in the opposite direction. Similarly, the gas in the airbag 8 on the other side flows back into the initial airbag 8. The airbags 8 on both sides expand and contract in turn, completing the simulated pressure on the kidneys and forming a dynamic pressure balance, ensuring that the kidneys are always subjected to uniform pressure and maintaining the normal morphological structure of the kidneys.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

When the initial gas in the air bag (8) on one side is insufficient to drive the spring (20) to contract, the spring (20) returns to its original state and drives the wind blocking rod (21) to block the ventilation duct (18) and the slideway (19), and the spring (14) also returns to its original state and rotates in the reverse direction to cause the wind plate (13) to rotate in the reverse direction. S7, the wind plate (13) rotates in the opposite direction to fan the gas inside the airbag (8) on the other side to circulate in the opposite direction. Similarly, the gas in the airbag (8) on the other side flows back into the initial airbag (8). The airbags (8) on both sides expand and contract in turn, simulating pressure on the kidney and forming a dynamic pressure balance, ensuring that the kidney is always subjected to uniform pressure and maintaining the normal morphological structure of the kidney.
