However, the embodiments described are not intended to limit the present invention.
[0026] Example
[0027] This embodiment provides a universal operating table for rodents, comprising: an adjustment assembly 100, which includes a lifting platform 110; and a working assembly 200, which includes an opening and closing mechanism 220 mounted on the lifting platform 110. The opening and closing mechanism 220 includes at least two hooks 223, a transmission mechanism 222, and an opening and closing handwheel 221. The opening and closing handwheel 221 is connected to at least one hook 223 through the transmission mechanism 222 to adjust the opening and closing degree between the hooks 223, and the opening and closing handwheel 221 is provided with a scale.
[0028] The universal rodent operating table of this embodiment, through the setting of the working component 200, specifically displays the degree of expansion of the thoracic and abdominal cavities of rodents through the scale of the graduated handwheel, enabling the intuitive acquisition of data during surgical experiments. This provides accurate data reference for subsequent teaching, research and recording. In addition, this operating table is compatible with rodents of different sizes, making it sufficient to accommodate the surgery of commonly used large-sized laboratory mice, thus solving the need for conventional operating tables to be replaced for laboratory mice of different sizes.
[0029] See Figure 1 As shown, in this embodiment, the adjustment component 100 is supported below the working component 200. The adjustment component 100 is used to adjust the specific operating height and angle of the actual surgical experiment. The working component 200 is used to carry the experimental mouse and open the incision. Specifically, during the operation, the experimental mouse is located inside the opening and closing mechanism 220 and the degree of opening of its incision is adjusted by the opening and closing mechanism 220 to facilitate the operator to make specific observation operations.
[0030] See Figure 1 and Figure 2 As shown, the working assembly 200 also includes a tilting mechanism 210. The tilting mechanism 210 has a tilting platform 212 connected to the lifting platform 110 and rotating around its connection with the lifting platform 110. An opening and closing mechanism 220 is disposed on the tilting platform 212 and moves synchronously with the tilting mechanism 210. In this embodiment, the opening and closing mechanism 220 is disposed at the center of the tilting platform 212 and is used to support the experimental mouse. Figure 1 The general-purpose rodent operating table shown is used as a reference. One end of the tilting platform 212 is connected to the lifting platform 110. An inclined hinge 213 is provided between the two to limit the tilting angle of the tilting platform 212. The included angle between the tilting platform 212 and the lifting platform 110 is 0° to 60°, which increases the flexibility of this general-purpose rodent operating table and facilitates surgical experiments and results display. Specifically, in this embodiment, the tilting mechanism 210 also includes a support frame 211. On the one hand, the tilting platform 212 in this embodiment can be angle-positioned by the support frame 211 after adjusting the tilting angle, thereby improving the stability of the operating table and preventing the tilting platform 212 from changing angle. Specifically, one end of the support frame 211 supports the lower surface of the tilting platform 212, and the other end supports the upper surface of the lifting platform 110. In other embodiments, two or more support frames 211 may be set according to the actual use process and weight of the tilting table 212, or an angle limiting mechanism 111 may be set on the tilting table 212 to achieve the same effect of stable tilting angle. The present invention does not impose specific limitations on this.
[0031] In this embodiment, a cooling component 2121 is also provided on the tilting table 212. During general surgical procedures, high ambient temperatures often lead to rapid tissue inactivation, which significantly impacts the success rate of the surgery and the effectiveness of the research. According to industry experience, in mice that have just died, the heart cells are almost completely dead after about 15 minutes at room temperature, and the liver cells are almost completely dead after about 30 minutes. However, at low temperatures, the rate of cellular metabolism in organisms slows down significantly, thus prolonging the time it takes for organ cells to die and increasing the success rate of surgical experiments. Temperature control is particularly important in major surgeries, organ transplants, and heart-related surgeries. Current procedures typically use ice blankets, ice towels, or ice packs. Low-temperature instruments such as blocks are placed in the axilla, neck, groin, and femoral arteries of laboratory mice. However, these instruments have poor temperature control and need to be frequently changed during surgery, increasing contamination of the operating table and placing a significant burden on the operators. In this embodiment, the cooling component 2121 can slow down the inactivation rate of biological tissue without causing contamination, increasing the success rate of surgical experiments. Specifically, the cooling component 2121 consists of a semiconductor cooling chip and a heat dissipation component. During use, it cools through the Peltier effect, with a specific cooling temperature range of approximately 3°C to 5°C below the body temperature of the active laboratory mouse. Furthermore, the body temperature of a typical laboratory mouse is approximately 37°C, so under normal use, the cooling component 2121 can maintain a constant temperature of 32°C to 34°C. Specifically, in this embodiment, the cooling component 2121 is preferably a bendable cold light source, thereby further reducing the impact of ambient temperature on biological tissue.
[0032] In this embodiment, the tilting table 212 is also provided with a plurality of guide channels 2122. The plurality of guide channels 2122 are arranged at intervals on the tilting table 212. The arrangement of the guide channels 2122 can discharge the liquid waste generated during the operation at any time to reduce its interference with the operation process.
[0033] See Figures 2 to 4As shown, the center of the working surface of the tilting table 212 is the surgical space. In this embodiment, two hook frames 223 are provided in the surgical space. The two hook frames 223 are arranged at intervals along the width direction of the operating table and are symmetrically arranged around the surgical space. Any hook frame 223 can move along the width direction of the operating table to realize the relative opening and closing between the two hook frames 223. In this embodiment, the working component 200 also includes multiple hook lines 224 connected to the hook frames 223 and whose length is adjustable. Specifically, each hook frame 223 is provided with multiple grooves arranged at intervals along its length extension direction for connecting the hook lines 224. The hook lines 224 can... The hooks can be connected to any groove to adjust the actual installation position. Furthermore, this embodiment has four hook lines 224, with two hook lines 224 connected to each hook frame 223. The connection length of any hook line 224 can be adjusted to suit experimental mice of different sizes. Furthermore, in this embodiment, before the experiment, the length of the hook line 224 in the groove can be adjusted by estimating the size of the experimental mouse to preliminarily adjust the size of the incision. If further adjustment of the incision opening degree is needed during the operation, the hook frame can be moved using the opening and closing handwheel 221 to achieve fine-tuning of the opening degree. In this embodiment, the shortest vertical distance between two hook frames 223 is 52mm, as detailed in [link to details]. Figure 3 As shown, the maximum is 182mm; see details below. Figure 4 As shown, the movable opening distance of the two hook frames 223 is 0-130mm.
[0034] See Figures 1 to 4 As shown, in this embodiment, the opening / closing handwheel 221 is located on one side of the tilting table 212. The transmission mechanism 222 includes a transverse connecting rod and a longitudinal connecting rod, wherein the longitudinal connecting rod and the transverse connecting rod are located in the same plane and are perpendicular to each other. The longitudinal connecting rod rotates synchronously with the opening / closing handwheel 221. One end of the longitudinal connecting rod is connected to the opening / closing handwheel 221, and the other end is connected to the center of the transverse connecting rod. A gear set that can mesh with each other is provided at the junction of the transverse connecting rod and the longitudinal connecting rod. This structure can change the direction of the force when the longitudinal connecting rod rotates, thereby realizing the purpose of the transverse connecting rod rotating around its axis. Furthermore, the two ends of the transverse connecting rod are respectively converted from rotational driving force to translational driving force through the gear set, thereby realizing the opening and closing movement of the two hook frames 223. During this process, the opening / closing handwheel 221 can intuitively provide feedback on the actual movement distance of the hook frame 223 through the scale marked on it, thereby realizing the function of intuitively obtaining data in surgical experiments. See Figure 2 As shown, the opening and closing mechanism 220 also includes at least two limb fixing members 225. In this embodiment, the four fixing members 1113 are all disposed on the surface of the lifting platform 110 and are respectively disposed at the four corners around the guide groove 2122 to connect the four limbs of the experimental mouse.
[0035] See Figure 5 and Figure 6 As shown, the adjustment assembly 100 also includes a support platform 120, and a lifting platform 110 is connected to the support platform 120 and moves up and down above the support platform 120. In this embodiment, a limiting mechanism 111 is provided between the lifting platform 110 and the support platform 120, and the movement distance of the limiting mechanism 111 along the height direction of the lifting platform 110 varies from 0mm to 150mm. Further, in this embodiment, the support platform 120 is placed on the ground, and the support platform 120 and the lifting platform 110 are set as cubes with matching shapes. This structural setting of the lifting platform 110 can adjust the working height of the tilting table 212 during actual use, thereby further increasing the flexibility of the use of this operating table. In this embodiment, two limiting mechanisms 111 are spaced apart along the length of the lifting platform 110. Each limiting mechanism 111 includes two limiting pulleys 1111 respectively disposed on the lifting platform 110 and the support platform 120 along the height direction of the operating table. A limiting chain 1112 is connected between the two limiting pulleys 1111. The limiting chain 1112 can limit the maximum distance between the lifting platform 110 and the support platform 120 to avoid affecting the overall stability of the operating table during use after the lifting platform 110 rises excessively. In this embodiment, a fixing member 1113 is also provided between the lifting platform 110 and the tilting platform 212. The fixing member 1113 is used to ensure that the two are always stably connected when they are in contact. In other embodiments, the installation position and number of components in the limiting mechanism 111 can be adjusted according to the actual use. This invention does not specifically limit this. Specifically, when the support platform 120 is in contact with the lifting platform 110, that is, when the lifting platform 110 is in the lowest position, see [reference needed]. Figure 5 As shown, the structure when the lifting platform 110 rises to its maximum height along the support platform 120 is described in [reference needed]. Figure 6 As shown.
[0036] Furthermore, in this embodiment, the lifting platform 110 is also provided with a sewage discharge section 112 and a lighting mechanism 113. Further, the sewage discharge section 112 includes a sewage discharge trough 1121 located at one end of the lifting platform 110, which has at least one sewage discharge port 1122. During the operation, blood and sewage flow into the sewage discharge trough 1121. The sewage discharge trough 1121 can temporarily store surgical waste. The sewage discharge port 1122 is connected to an external air extraction unit 1123. When surgical waste clogs the sewage discharge port 1122, the air extraction unit 1123 can form a micro-negative pressure zone. The exhaust gas and other polluting gases near the sewage discharge port 1122 will flow into the micro-negative pressure zone under its action, and then be extracted and discharged by the air extraction unit 1123 and recycled. This process is repeated to ensure that the air is clean and odorless during the surgical experiment, and that the surface of the operating table is always clean and tidy without blood accumulation. Furthermore, in this embodiment, components such as the air extraction unit 1123, the refrigeration component 2121, and the lighting mechanism 113 are all fixed by screws or quick-release structures. Therefore, all of the above components can be disassembled independently. When a component fails, only the faulty part needs to be replaced, without the need for a complete replacement. This further improves the flexibility of the invention and reduces maintenance costs.
[0037] The support platform 120 is internally equipped with a lifting handwheel 121, a lifting rod 122, and a buffer 123. The lifting handwheel 121 is connected to the lifting rod 122, the lifting platform 110 is located at one end of the lifting rod 122, and the buffer 123 is sleeved around the lifting rod 122. In this embodiment, the lifting handwheel 121 can drive the lifting rod 122 to move along the height direction of the operating table. The buffer 123 is used to prevent excessive collision or impact damage between the lifting platform 110 and the support platform 120 when the lifting platform 110 descends. Correspondingly, in other embodiments, the buffer 123 can also be made of elastic rubber, cushioning sponge, or other structures with elastic cushioning function.
[0038] The following describes the specific usage process and principle of the universal rodent operating table in this embodiment:
[0039] First, the operator needs to fix the experimental mouse on the tilting table 212, then adjust the surgical space to the required height by adjusting the component 100, and then flip the tilting table 212 to the required angle by the tilting mechanism 210. In this embodiment, it is preferably 45°, and then the surgical experiment can begin.
[0040] During the operation, the operator can use the opening and closing mechanism 220 to open the surgical incision of the experimental mouse to expose the internal condition. At this time, the operator can adjust the specific degree of opening of the incision according to the experimental requirements and record the specific data of opening through the scale on the handwheel for subsequent experiments. During the above experiment, the sewage discharge section 112 and the guide channel 2122 can ensure that the air is clean and odorless during the surgical experiment, and that the surface of the operating table is always clean and tidy, with no blood accumulation.
[0041] In summary, the universal rodent operating table of the present invention, through the setting of the working component 200, can specifically display the degree of expansion of the thoracic and abdominal cavities of rodents on the scale of the graduated handwheel, thus realizing the function of intuitively obtaining data in surgical experiments. This provides accurate data reference for subsequent teaching, research and recording. In addition, this operating table is compatible with rodents of different sizes, making it sufficient to accommodate the surgery of commonly used large-sized laboratory mice, thus solving the need for changing operating tables for laboratory mice of different sizes.
[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
