Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical treatment, in particular to a laparotomy experiment workbench. Background Art
[0002] Mouse laparotomy experiment is a common animal experimental method used to study the behavior, physiology and pathology of mice. In this experiment, researchers usually open the mouse's chest cavity to observe and record the conditions of the mouse's heart, lungs and other organs.
[0003] During the experiment, the laboratory mice need to be anesthetized, and their limbs need to be fixed with fishtail clamps or rubber bands before an open abdominal experiment is performed. Due to the small size of the laboratory mice, it is difficult to quickly fix the limbs with rubber bands, which prolongs the time required for the experiment. The fishtail clamps and rubber bands cause varying degrees of damage to the limbs of the laboratory mice, resulting in blood circulation problems and local ischemia, and at the same time increase the risk of infection for the laboratory mice, thereby affecting the results of the experiment and the survival rate of the laboratory mice. At the same time, the fishtail clamps are placed on the surface of the operating platform, causing the operating platform to become larger and inconvenient to store. If they are removed, they need to be stored separately, which may cause them to fall off, which is not conducive to the subsequent cleaning and disinfection process.
[0004] Therefore, the utility model provides a laparotomy experiment workbench to meet the needs. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a laparotomy experimental workbench to solve the problem that the traditional fixing structure is cumbersome, thereby causing damage to the limbs of experimental mice and making it inconvenient to clean the experimental table later.
[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0007] A laparotomy experiment workbench includes an experimental platform, a fixing ring is inserted into the top of the experimental platform, four sets of sliding grooves are opened on the top of the experimental platform, and T-shaped grooves are provided at the ends of the sliding grooves; a fixing component is provided on the sliding groove, and the fixing component is used to fix the limbs of the experimental mouse; a limiting component is provided in the T-shaped groove, and the limiting component is used to fix the fixing component after being stored.
[0008] Optionally, the limiting assembly includes a clamping arc plate symmetrically installed above the T-slot, and two groups of arc-shaped contact plates are symmetrically installed on the inner side wall of the T-slot.
[0009] Optionally, the fixing assembly includes a fixing base, and two groups of elastic sheets are symmetrically mounted on the top of the fixing base, and one end of the two groups of elastic sheets is fixedly connected to a limb fixing plate.
[0010] Optionally, a connecting seat is provided at the bottom of the fixed base, and a limiting round rod is provided at the bottom of the connecting seat, and the connecting seat is fixedly connected to the outer wall of the limiting round rod; a corrugated spring piece is provided inside the sliding groove, and the limiting round rod is inserted inside the corrugated spring piece, and the limiting round rod can slide along the inner side wall of the corrugated spring piece.
[0011] Optionally, a fixing rod is fixedly connected to the inner wall of the sliding groove, a limiting ring is sleeved on the outer wall of the fixing rod, two groups of corrugated springs are symmetrically installed on the outer wall of the limiting ring, and the corrugated springs are a corrugated elastic structure.
[0012] Optionally, one end of the corrugated spring piece away from the limiting ring is fixedly connected to the limiting piece, and one end of the corrugated spring piece close to the limiting piece is fixedly connected to the fixing piece.
[0013] Optionally, the limiting piece conflicts with the fixing piece.
[0014] Optionally, the limb fixing plate is a corrugated structure.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects:
[0016] In the above scheme, by setting up a fixing component, not only can the limbs of the experimental mouse be fixed, but it can also be adjusted according to the body size of different experimental mice. The fixing method is more comfortable and efficient, thereby shortening the time required for the experiment.
[0017] By arranging limb fixing plates in the fixing assembly, there are four groups of limb fixing plates. The two groups of limb fixing plates close to the above-mentioned fixing ring are used to fix the upper limbs of the experimental mouse, and the two groups of limb fixing plates away from the fixing ring are used to fix the lower limbs of the experimental mouse. The structure of each group of limb fixing plates is the same, so that the experimental mouse can lie on its back in a spread-eagle position above the experimental platform, so that the chest cavity is facing the medical staff. At the same time, the surface of the limb fixing plate is smooth and made of rubber. The curvature of the surface adapts to the contour of the limbs of the experimental mouse, which can quickly fix the limbs while solving the problem of blood circulation problems caused by excessively tight fixation of the limbs.
[0018] By setting a limit component, the position of the fixed component after storage can be fixed, thereby avoiding the overall space occupied by the device being too large, and at the same time avoiding the problem of the limb fixation plate being damaged or dropped when placed on the surface of the experimental platform.
[0019] By cooperating with each other, the fixing components and the limiting components can be adjusted accordingly according to the body sizes of different experimental mice during the experiment. The fixing method is more convenient and can protect the limbs of the experimental mice from damage to the greatest extent, ensuring that the experimental results and the survival rate of the experimental mice are not affected. After the experiment is completed, it can also be fixed in the experimental platform, which improves the utilization rate of space and avoids the phenomenon of being left behind.

[0035] like Figures 1 to 6As shown, an embodiment of the present invention provides an open abdominal experimental workbench, including an experimental platform 1, a fixing ring 2 is inserted into the top of the experimental platform 1, and four groups of sliding grooves 3 and four groups of T-slots 4 are symmetrically opened on the top of the experimental platform 1, the T-slots 4 correspond to the sliding grooves 3 one by one, and the T-slots 4 are located at the ends of the sliding grooves 3; a fixing component, the fixing component is used to fix the limbs of the experimental mouse, and the fixing component is connected to the experimental platform 1; a limiting component, the limiting component is used to fix the fixing component after storage, and the limiting component is connected to the T-slot 4, specifically, the sliding groove 3 and the T-slot 4 are an integrated structure, and the connection between the sliding groove 3 and the T-slot 4 is a smooth rounded corner.
[0036] like Figure 2 、 Figure 4 and Figure 6 As shown, the fixing assembly includes a fixing rod 14 fixedly connected to the inner wall of the sliding groove 3, the outer wall of the fixing rod 14 is sleeved with a limiting ring 13, and two groups of corrugated springs 12 are symmetrically installed on the outer wall of the limiting ring 13. The corrugated spring 12 is a corrugated elastic structure. The end of the corrugated spring 12 away from the limiting ring 13 is fixedly connected to the limiting piece 15, and the end of the corrugated spring 12 close to the limiting piece 15 is fixedly connected to the fixing piece 16. The limiting piece 15 conflicts with the fixing piece 16. The inner wall of the corrugated spring 12 is plugged with a limiting round rod 11, and the limiting round rod 11 can slide on the inner wall of the corrugated spring 12, and the limiting ring 13 is C-shaped. The type open structure has an opening connected to two corrugated spring pieces 12, one end of a corrugated spring piece 12 is connected to the limiting piece 15, and one end of the other corrugated spring piece 12 is connected to the fixing piece 16. Therefore, the corrugated spring piece 12, the limiting ring 13, the limiting piece 15 and the fixing piece 16 are an integrated structure, and the outer wall of the limiting piece 15 conflicts with the inner wall of the fixing piece 16, wherein the limiting ring 13 is connected to the fixing rod 14. When cleaning and disinfection is required, the corrugated spring piece 12 is rotated with the fixing rod 14 as the center axis so that the corrugated spring piece 12 is perpendicular to the sliding groove 3, which is convenient for cleaning the corrugated spring piece 12 and the inner wall of the sliding groove 3.
[0037] Specifically, the corrugated spring piece 12 is an elastic structure, which is composed of a plurality of arc-shaped pieces to form a corrugated shape, and the limiting rod 11 is cylindrical, which is adapted to the contour of the arc-shaped piece, and the connection point of each arc-shaped piece tends to bend downward. When the position of the above-mentioned fixing component needs to be adjusted, the limiting rod 11 can move on the inner side wall of the corrugated spring piece 12. At this time, the opposing arc-shaped pieces can clamp the limiting rod 11 from both sides, and at the same time, the downward bending part of the arc-shaped piece can limit the limiting rod 11 to fix the position. When the limiting rod 11 moves to the end of the corrugated spring piece 12 away from the limiting ring 13, since the curvature of the curved surface formed by the limiting piece 15 and the fixing piece 16 is greater than the diameter of the limiting rod 11, the limiting rod 11 can be rotated therein, which is convenient for subsequent storage. At the same time, the limiting rod 11 can also be manually removed from the gap between the limiting piece 15 and the fixing piece 16, which is more convenient for subsequent cleaning.
[0038] like Figure 2 、 Figure 4 and Figure 5 As shown, the outer wall of the limiting circular rod 11 is fixedly connected to the connecting seat 10, and the upper end of the connecting seat 10 is fixedly connected to the fixed base 7. Two groups of elastic sheets 8 are symmetrically installed on the top of the fixed base 7. The elastic sheets 8 are elastic structures, and one end of the two groups of elastic sheets 8 is fixedly connected to the limb fixing plates 9. There are four groups of limb fixing plates 9, and the limb fixing plates 9 are corrugated structures. Specifically, there are four groups of fixed bases 7, which are respectively located on the surfaces of the above-mentioned four groups of sliding grooves 3. The surface of the fixed base 7 is provided with an empty groove. The limb fixing plate 9 at its middle position is composed of two symmetrical corrugated splints, which are connected to the fixed base 7 through the elastic sheets 8. Since the elastic sheets 8 are elastic structures, the two limb fixing plates 9 can move to both ends at the middle position of the fixed base 7, thereby fixing the limbs of the experimental mouse.
[0039] Furthermore, there are four groups of limb fixing plates 9. The two groups of limb fixing plates 9 close to the above-mentioned fixing ring 2 are used to fix the upper limbs of the experimental mouse, and the two groups of limb fixing plates 9 away from the fixing ring 2 are used to fix the lower limbs of the experimental mouse. The structure of each group of limb fixing plates 9 is the same, so that the experimental mouse lies on its back in a big letter shape above the experimental platform 1, so that the chest cavity is facing the medical staff, which is convenient for the laparotomy experiment. It should be noted that the top of the limb fixing plate 9 is an outward-turned rounded corner, and its connection is an inward-turned rounded corner. The medical staff can turn the outward-turned rounded corner to adjust the position. Under the action of the elastic sheet 8, the limb fixing plate 9 is ordered to move to both ends. At this time, the limbs of the experimental mouse are placed from top to bottom on the inner side of the two limb fixing plates 9 for fixation. The inward-turned rounded corners can be used to fix the position of the experimental mouse's limbs for a second time, avoiding the unstable fixation of the limbs affecting the progress of the experiment, thereby increasing the portability of the limb fixation of the experimental mouse. At the same time, the surface of the limb fixing plate 9 is smooth and made of rubber. The curvature of its curved surface adapts to the contour of the limbs of the experimental mouse, which can quickly fix the limbs while solving the problem of blood circulation caused by excessively tight fixation of the limbs.
[0040] like Figures 1 to 3 As shown, the limiting assembly includes a clamping arc plate 6 symmetrically installed above the T-slot 4, and two groups of arc-shaped contact plates 5 are symmetrically installed on the inner wall of the T-slot 4. The above-mentioned limb fixing plate 9 can be stored in the T-slot 4, and the clamping arc plate 6, the arc-shaped contact plate 5 and the T-slot 4 are an integrated structure. There is an inward-turned fillet on the top of the clamping arc plate 6, which can clamp the inward-turned fillet of the above-mentioned limb fixing plate 9, and the surface of the arc-shaped contact plate 5 is smooth and can interfere with both sides of the limb fixing plate 9. With the cooperation of the arc-shaped contact plate 5 and the clamping arc plate 6, the limb fixing plate 9 is locked in the T-slot 4, so that the overall space occupied is small, which is convenient for storage and avoids the phenomenon of being left behind.
[0041] The working principle of this utility model is:
[0042] First, move the clamping arc plate 6 to both sides, take out the four sets of limb fixing plates 9 from the T-slot 4, and make them perpendicular to the surface of the experimental platform 1. Move the fixed base 7 according to the size of the experimental mouse. At this time, the limiting round rod 11 moves in the corrugated spring piece 12. Since the corrugated spring piece 12 is an elastic structure, it can not only make the limiting round rod 11 move, but also rely on its corrugated structure to fix the position of the limiting round rod 11. Place the limbs of the experimental mouse from top to bottom on the inner side of the two limb fixing plates 9, and fix the limbs under the action of the two elastic plates 8. Make the experimental mouse lie on its back on the surface of the experimental platform 1 in a big shape, and place the fixing ring 2 in the mouth of the experimental mouse to facilitate the intubation operation of the experimental mouse. The surface of the limb fixing plate 9 is smooth and made of rubber, which can reduce the discomfort of the experimental mouse and avoid the limbs being fixed too tightly, resulting in blood circulation problems that affect the experimental results and the survival rate of the experimental mouse.
[0043] After the experiment is over, since the connecting seat 10, the limiting round rod 11, the fixed base 7, the elastic sheet 8 and the limb fixing plate 9 are an integrated structure, the limiting round rod 11 can be taken out at the gap between the limiting sheet 15 and the fixing sheet 16, which is convenient for cleaning and disinfecting the whole. At the same time, the limiting ring 13 can also rotate on the outer wall of the fixing rod 14, and can be perpendicular to the sliding groove 3, thereby realizing the cleaning of the corrugated spring sheet 12. Finally, the cleaned limiting round rod 11 can be inserted into the corrugated spring sheet 12 from the gap between the limiting sheet 15 and the fixing sheet 16. The limiting round rod 11 can rotate in the cavity formed by the limiting sheet 15 and the fixing sheet 16, so that the fixed base 7 and the limb fixing plate 9 can be placed in the T-slot 4 as a whole, and the limb fixing plate 9 can be locked under the action of the clamping arc plate 6 and the arc contact plate 5, so that the space occupied by the overall device is small, and at the same time, the limb fixing plate 9 can be prevented from being damaged or lost on the surface of the experimental platform 1.
[0044] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the preferred embodiments of this invention, but those skilled in the art can fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion about the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
