Description

Technical Field

[0001] The invention belongs to the technical field of operating tables, and more specifically is a special operating table for medical DPF pig xenotransplantation. Background Art

[0002] The medical DPF pig operating table is a platform device specially used for performing surgical operations on medical donor pigs (Donor Pig for Medicine, DPF pigs). It plays a key role in related operations involving pig organs and tissues for medical research, transplantation, etc. This operating table is mainly made of high-strength materials, which can withstand the weight of the pig and various external forces during the operation, ensuring that the operating table will not shake or shift during the operation, and providing a reliable support basis for the operation. It has a height adjustment function, which is convenient for surgical personnel of different heights to operate and improve the success rate and convenience of the operation. It is also equipped with an anesthesia and monitoring equipment integration module and a special anesthesia gas delivery device, which can accurately control the dosage and delivery speed of anesthetic drugs, ensure that the pig is in a suitable anesthesia state during the operation, reduce pain and ensure the smooth progress of the operation. At the same time, it integrates a variety of physiological parameter monitoring equipment, such as electrocardiogram monitoring, blood pressure monitoring, blood oxygen saturation monitoring, etc., to obtain the vital signs data of the pig in real time, so that the surgical team can grasp the physical condition of the pig in time and respond to possible emergencies.

[0003] Since the pig's body temperature may fluctuate due to various factors during the operation, the operating table is equipped with a temperature control device to keep the pig's body temperature relatively stable, avoiding adverse effects on the pig's physiological functions due to abnormal body temperature, and helping to improve the safety and success rate of the operation.

[0004] In addition, there is also a protective barrier setting. Some operating tables will be equipped with protective barriers, such as transparent covers, etc., which can prevent blood and body fluids from splashing during the operation and protect the operating personnel; on the other hand, it also helps to maintain a relatively sterile environment in the operating area and reduce the interference of external factors on the operation. However, although the setting of protective barriers such as covers can prevent blood stains from splashing outside the operating table, the blood stains are left on the wall of the operating room (protective barrier), which may affect the line of sight of the operating personnel, and when they gather to a certain extent, they may drip on the DPF pigs, causing inconvenience to the operation. Secondly, during the operation, DPF pigs often bleed heavily or spray body fluids. These blood stains flow down through the pigs and are easily accumulated in the operating room, which in turn affects the normal operation and seriously affects the pigs' postoperative maintenance monitoring. In addition, the existing operating tables mostly use scissor-type lifting brackets for height lifting, but the driving force of the lifting structure generally comes from the driving component at the bottom. Once the driving component at the bottom loses control, the entire lifting mechanism will directly fail, which will cause the operating table to tip over, causing irreparable losses to the surgical experiment.

DETAILED DESCRIPTION

[0020] Based on the several drawings in the embodiments of the present invention and referring to the following text description, a relatively clear and complete introduction of the technical scheme in the embodiments of the present invention can be made. However, it should be understood that the embodiments mentioned in this article are only one or several specific methods of the present invention, and not all implementation structures or method steps.

[0021] like Figure 1 As shown, in one embodiment of the present invention, a medical DPF pig xenotransplantation special operating table is introduced in detail, the operating table specifically includes a lifting bracket and an operating chamber 2 installed on the top of the lifting bracket, and the operating chamber 2 is made of transparent material for easy observation. More specifically, a bottom plate 3 for placing the DPF pig is specifically arranged horizontally at the bottom of the operating chamber 2, as shown in FIG. Figure 1-3 , on this bottom plate 3 there are a number of through holes 301 for blood to flow down, so that during surgery, if there is blood flowing out, it will not gather on the bottom plate 3, avoiding the accumulation of blood stains and affecting the surgery. In addition, a number of blood troughs 302 connected to the through holes 301 are also provided in the bottom plate 3, and the blood in the through holes 301 can flow into the blood troughs 302 and be discharged to the outside of the operating chamber 2 through the blood troughs 302. Specifically, the blood troughs 302 can be connected to the bottom ends of these through holes 301 respectively, and the blood troughs 302 are connected to the corresponding through holes 301 through a number of branch grooves. In addition, the lifting bracket in this embodiment includes a number of pairs of connecting rods 1 arranged crosswise with each other, and each pair of connecting rods 1 cross each other in the center to form an X shape and are hinged to each other, and the ends of the two opposite pairs of connecting rods 1 are hinged to each other, forming a shape as shown in the figure. Figure 1 When specifically manufactured, the free ends of the two pairs of connecting rods 1 at the top and the bottom are respectively connected to the top driving component and the bottom driving component, and when the bottom driving component drives the free ends of the corresponding two connecting rods 1 to move toward / away from each other, the top driving component drives the free ends of the corresponding two connecting rods 1 to move toward / away from each other at the same speed, thus forming a dual driving and locking function, and more stably maintaining the height of the surgical chamber 2 after lifting.

[0022] Continue reading Figure 1-3 The present surgical chamber 2 is also provided with a rectangular fence 4, which is fixedly arranged on the upper surface of the bottom plate 3, and at the two diagonal corners of the surgical chamber 2, air inlet ducts and air outlet ducts 7 are specially arranged, wherein the air inlet duct is connected to the air filter device to continuously provide sterile fresh air. Storage boxes 8 are also provided on the left and right sides of the fence 4, respectively, and the storage boxes 8 are used to store surgical instruments and drugs, as well as pipelines of anesthesia monitoring equipment, so that they can be easily taken during surgery. Hooks are also fixed on the fence 4, and these hooks are used to hang hanging bottles, so that infusion and other operations can be performed during surgery.

[0023] During the operation, some tissues and organs, or corpses after the operation, will be produced, so there is a corpse recovery port at the bottom of one side of the operating chamber 2, and the corpse recovery port is used to connect to the corpse storage container to store tissues and organs or corpses. In specific practice, a circle of steel pipes (not shown in the figure) can be provided around the edge of the bottom plate 3, and at least four binding belts and four limb restraints can be freely moved and fixed on the steel pipes through steel pipe buckles to bind and fix the DPF pigs. Among the blood troughs 302 mentioned above, at least one of the blood troughs 302 is arranged along the central axis of the bottom plate 3, serving as the main blood trough 302 to discharge blood and dirt, and its cross-section is V-shaped, which is conducive to thorough drainage.

[0024] During the operation, blood stains may splash onto the inner wall of the operating chamber 2, thereby blocking the line of sight, or accumulated blood stains may drip during the operation, affecting the operation. Therefore, in this embodiment, it is recommended that Figure 1-2 As shown, a scraper 5 is provided in the operating room 2 in a horizontally sliding manner. The cross section of the scraper 5 is Π-shaped. The outer cleaning surface of the scraper 5 is respectively slidably attached to the inner top wall and the front and rear side walls of the operating room 2. Figure 4 As shown, a first magnet is fixed in the scraper 5, and a second magnet 6 is closely attached to the outside of the operating chamber 2. The two magnets attract each other, so that when the second magnet 6 is moved horizontally, the first magnet and the scraper 5 can slide horizontally together in the operating chamber 2 to wipe the blood stains on the inner wall of the operating chamber 2. Only then can magnetic drive be achieved, and no additional parts will be added in the operating chamber 2. Therefore, the space occupied in the operating chamber 2 can be minimized and pollution of the environment in the chamber can be avoided as much as possible.

[0025] like Figure 4-5As shown, the scraper 5 in this embodiment includes a cleaning cotton cover 501 in a Π shape, and a lining frame 502 in a Π shape, the cleaning cotton cover 501 is fixedly sleeved on the outer side of the lining frame 502, and a connecting block 503 is vertically and integrally provided in the center of the inner side of the lining frame 502, and the connecting block 503 is axially slidably passed through by a horizontally arranged guide rod 504, so that the connecting block 503 can slide axially along the guide rod 504, and the cross section of the guide rod 504 is rectangular, so that the entire scraper 5 can be stably and reliably moved in a straight line to wipe the area of ​​the inner wall of the operating chamber 2 that may affect the surgical operation. In a specific implementation, a handle 9 for hand holding is fixed on the surface of the second magnet 6 mentioned above for holding, and a limit groove (not shown in the figure) can be provided on the outer wall of the operating chamber 2 when necessary, so that the second magnet 6 can move in a straight line, and in order to move smoothly, a cotton pad (not shown in the figure) can be adaptively fixed at the bottom of the second magnet 6 to slide without wearing the outer wall of the operating chamber 2. In the above structural design, a connecting ring 506 can be fixedly installed on the left and right sides of the connecting block 503 by bolts for assembly and disassembly. Specifically, the connecting ring 506 is coaxially sleeved on the outside of the guide rod 504, and the end face of the connecting ring 506 is connected to the elastic telescopic sleeve 505 tube. The elastic telescopic sleeve 505 tube can be axially telescopic, that is, it can be freely stretched or shortened. Its structure can be made of elastic material, or it can be as Figure 7 As shown, an elastically retractable bellows structure is adopted, and the elastically retractable sleeve 505 is coaxially sleeved on the outside of the guide rod 504, so that when the operator holds the handle 9 outside the operating chamber 2 to move the second magnet 6, the connecting block 503 can slide linearly along the axial direction of the guide rod 504 to wipe off the blood stains on the inner wall of the operating chamber 2, and the guide rod 504 is always protected by the elastically retractable sleeve 505 to prevent the guide rod 504 from being contaminated and affecting the guiding performance, and to prevent friction debris that may fall due to axial sliding cooperation from entering the bottom plate 3 in the operating chamber 2.

[0026] As one of the specific implementation structures, in this embodiment, the top driving component and the bottom driving component each include a table 17, a screw rod 10 and a threaded block 11. The top driving component can be referred to in Figure 3 , bottom drive components can be found in Figure 6 In the above structure, a mounting groove is horizontally provided in the table 17, and the mounting groove is used for the screw rod 10 to be installed horizontally and can rotate freely. One end of the screw rod 10 is connected to a driving device for transmission to realize in-situ rotation; the threaded block 11 is horizontally slidably connected to the mounting groove and cannot rotate, so as to realize the transmission of the screw rod 10, and the threaded block 11 is hinged with the free end of the corresponding connecting rod 1 to move with the connecting rod 1, thereby realizing the lifting function of the lifting bracket and adjusting the height of the operating chamber 2. When making it specifically, you can refer to the following structure: Figure 3 or Figure 6As shown, the installation groove mentioned above includes a first strip groove body 1401, a connecting seam 1402, and a second strip groove body 1403, which are all horizontally extended. The connecting seam 1402 is located between the two groove bodies and directly connects the two. The width of the connecting seam 1402 is smaller than the width of the two strip groove bodies. The threaded block 11 specifically includes a main body, a connecting neck 13 and a driving block 12, wherein the main body is fixed as a whole through the connecting neck 13 and the driving block 12, the main body is horizontally slidably installed in the first strip groove body 1401 and is threadedly sleeved with the screw rod 10, the connecting neck 13 passes through the connecting seam 1402, and the driving block 12 contacts the free end of the corresponding connecting rod 1 to push it to move horizontally.

[0027] like Figure 3 A more optimal design structure is that there are two connecting necks 13 in the top driving component of this embodiment, which are used to fix two driving blocks 12 respectively, that is, Figure 3 The first driving block 1201 and the second driving block 1202 are respectively located at the front and rear sides of the free end of the connecting rod 1. This is to ensure that when the connecting column moves horizontally with the threaded block 11, the two driving blocks 12 can move the free end of the connecting rod in a front-to-back clamping manner, which can not only prevent the ends of the connecting rod 1 from moving away from each other, but also prevent them from getting close to each other, thereby completely fixing the lifting bracket.

[0028] In specific practice, the driving block 12 of the bottom driving component is a Π-shaped handle structure, such as Figure 6 The middle section of the handle is coaxially installed in a roller 21. The outer surface of the roller 21 is covered with a wear-resistant rubber sleeve 20. The wear-resistant rubber sleeve 20 can frictionally contact with the table 17 of the bottom driving component. One side of the roller 21 is fixedly connected to the free end of the connecting rod 1. After the height is adjusted to the right position, the above-mentioned wear-resistant rubber sleeve 20 frictionally contacts with the surface of the table 17, which plays a certain auxiliary role in fixing the bottom end of the lifting bracket.

[0029] Finally, in the above embodiments, regarding the transmission design of the screw rod 10, specifically, the above drive device can be designed according to the following structures: First, if Figure 1 The driving device of this embodiment includes a first motor 18 and a second motor 19. The main shafts of the two motors are respectively connected to the ends of the two screw rods 10, and each is driven separately to keep the threaded holes moving synchronously. This is the simplest way, but it requires two synchronous motors.

[0030] Second, if Figure 1 ,as well as Figure 3 and Figure 6The driving device in this embodiment includes two transmission wheels 15 respectively fixed on two screw rods 10 driven by a motor 22, and the two transmission wheels 15 are synchronously driven by a transmission belt 16, and one end of the transmission belt 16 is wound around a receiving wheel 23 fixed on the main shaft of the motor 22, and then wound around the two transmission wheels 15 in sequence, and finally wound around a wheel disc. In a specific implementation, the other end of the transmission belt 16 is wound around a wheel disc (not shown in the figure), and it is wound around the wheel disc for multiple turns to sufficiently release or store the transmission belt 16. During use, when the motor 22 is started to rotate, as an operation scenario, it is equivalent to releasing the transmission belt 16 from the wheel disc to the receiving wheel 23, thereby ensuring that the transmission belt 16 and the two transmission wheels 15 continue to be synchronously driven, and the movement of the transmission belt 16 will not be affected by the two transmission wheels 15 moving away from or approaching each other as their respective screw rods 10, which is very clever; in implementation, it is best that the motor 22 and the driving device speed of the wheel disc match to ensure that the transmission belt 16 is always reliably tensioned. In addition, as a more optimal design, the driving block 12 of the bottom driving component may include a first block and a second block, the two blocks are elastically connected by a pressure spring (not shown in the figure, the specific structure can be adaptively designed), and the second block is in contact with the free end of the connecting rod to make the driving of the free end of the connecting rod 1 more sufficient and to play a pre-tightening role at the same time.

[0031] As a third embodiment, the driving device includes a vertically telescopic hydraulic rod (not shown in the figure), the hydraulic rod is connected to a rack (not shown in the figure), the rack is meshed with two gears (not shown in the figure) at the same time, the two gears are respectively fixed at the ends of two screw rods 10, and the transmission is realized by a rack and pinion mechanism. The rack of this structure is relatively long, and as a rigid component, it occupies a very limited space when installed.

[0032] The present invention is not limited to the field involved in this implementation case, and some well-known structures or principles are not further described. However, ordinary technicians in the relevant field can theoretically know all the well-known technologies in this technical field before the application date or priority date, can fully master all the existing technologies in this technical field, and have the means and ability to apply these existing technologies for actual design and application. Under the technical enlightenment given by this application, technicians can improve and implement the present invention more comprehensively in combination with their own abilities. In addition, it should be pointed out that although the text and graphics of the above embodiments have shown the specific implementation occasions of the present invention, for ordinary technicians in this field, it is entirely possible to carry out a variety of obvious expansions and extensions on these embodiments without departing from the design concept of the present invention to form different embodiments, but this does not affect the scope of protection of the present invention, which is covered and embodied by the technical features of the claims and equivalent technical features.
