Description

Technical Field

[0001] The invention relates to the technical field of medical experimental equipment, in particular to a mouse aorta stripping and dissecting table. Background Art

[0002] Atherosclerosis is a disease that seriously endangers human health and is the main cause of coronary heart disease, cerebral infarction, and peripheral vascular disease. Lipid metabolism disorders are the pathological basis of atherosclerosis. Its characteristic is that the lesions of the affected arteries start from the intima. Generally, there is accumulation of lipids and complex carbohydrates, bleeding and thrombosis, followed by fibrosis and calcification, and gradual degeneration and calcification of the middle layer of the artery, resulting in thickening and hardening of the arterial wall and narrowing of the blood vessel lumen. The lesions often involve large and medium muscular arteries. Once they develop to the point of blocking the arterial lumen, the tissues or organs supplied by the artery will be ischemic or necrotic. Because the lipids accumulated in the intima of the artery appear yellow and porridge-like, it is called atherosclerosis.

[0003] Using animal models to study the occurrence and development of diseases is a simple, effective, convenient and reliable technical means. In particular, mice, which are small in size, reproduce quickly and have small individual differences, have always been the most widely used animals in clinical trials. In mouse experiments to study atherosclerosis, the experimenters need to dissect the mice, clean most of their internal organs, and then completely remove the mouse's aorta and its branches for subsequent in vitro experiments.

[0004] However, these animals have strong struggling and attacking abilities and are small in size. When the experimenters use the existing experimental tables to dissect or inject drugs on them, it is not only difficult to fix them, but also often difficult to control or even be scratched by the animals, which increases the difficulty of the experiment and affects the progress and accuracy of the experiment. In addition, the structure of most existing animal dissection tables is very simple and the function is single, which only meets the requirements of binding and positioning small animals during dissection. Since the experimenters need to use a large number of tools such as scissors, scalpels, blunt tools, tweezers and needles during mouse dissection, it is troublesome for the operators to take and put the tools during the dissection. The dissection table is not equipped with a device for storing tools, which brings certain troubles to the experimenters; and due to the characteristics of the aortic dissection experiment, the mice will bleed a lot of blood during the dissection experiment, and the operators also need to handle many organs, which will make the dissection table dirty and cannot be cleaned; and the existing dissection table is fixed in height and cannot be adjusted and tilted, which is not suitable for all on-site experimental situations, causing certain difficulties in the experimental process.

[0005] How to solve the above technical problems is the subject faced by the present invention. Summary of the invention

[0006] In order to solve the deficiencies of the prior art, the present invention provides a mouse aorta dissection dissection table with reasonable design, simple structure, safety and reliability, convenient access to dissection tools, the ability to lift and tilt the dissection table, and a cleaning function.

[0008] One end of the top surface of the movable plate is hinged to one end of the workbench, and the other end of the top surface of the movable plate is movably connected to the other end of the movable plate through a telescopic rod;

[0009] The top surface of the workbench is provided with a guide groove, the guide groove is connected to a drainage pipe, and the top of the workbench is provided with a faucet;

[0010] Tool racks are arranged on both sides of the movable plate.

[0011] The workbench is in the shape of a rectangular plate, and the guide groove and the fixing button are arranged on the top surface;

[0012] The guide groove includes three parts, all of which are arranged at the edge of the top surface of the workbench, and are respectively arranged on both sides of the workbench and on one side of the movable plate hinged to the workbench. The drainage pipe is provided with a plurality of guide grooves connected to the side of the movable plate hinged to the workbench;

[0013] The faucet is arranged on one end of the telescopic rod arranged on the workbench, and the faucet is connected to the water tank through a water inlet pipe and a water pump.

[0014] At least four first hinge seats are arranged on the top surface of the fixing plate, and the first hinge seats are arranged on both sides of the top surface of the fixing plate, at least two first hinge seats are arranged on each side, and the first hinge seats on both sides are symmetrically arranged, and each of the first hinge seats is rotatably connected to a first connecting rod;

[0015] The movable plate is located above the fixed plate and is arranged horizontally with the fixed plate. A second hinge seat is fixedly arranged on the bottom surface of the movable plate corresponding to the first hinge seat, and each of the second hinge seats is rotatably connected to a second connecting rod.

[0016] Each of the first connecting rods is rotatably connected to the corresponding second connecting rod, and when the number of the first articulated seats is greater than four, the connection points between two adjacent groups of the first connecting rods and the second connecting rods are connected via a third connecting rod;

[0017] The inner side of the first hinge seat is rotatably connected with a gear.

[0018] The sliding member comprises two symmetrically arranged Z-shaped sliding rods, each of which is divided into three sections, and the two sections located at both ends of the sliding rod are provided with racks, and the two sections of the racks on each sliding rod are meshed with the upper and lower parts of the two gears on the same side;

[0019] The two sliding rods are fixedly connected via a connecting rod, and the middle portion of the connecting rod is threadedly connected to the threaded rod.

[0025] When the present invention is actually used: the device is placed on a table or the ground, and the movable plate can be adjusted to be raised or lowered by turning the handle. The specific process is: after the handle is turned, the threaded rod rotates with the handle. Since the threaded rod is rotationally connected to the connecting rod of the sliding member, and the sliding member is limited by the sliding channel, the sliding member performs a translational motion as a whole. When the sliding rods on both sides of the sliding member move, the two racks on each sliding rod drive the gear to rotate. When the gear rotates, the first connecting rod fixedly connected to the gear starts to rotate. At this time, due to the action of the third connecting rod, all the first connecting rods start to rotate upward or downward. Since the first connecting rod is rotationally connected to the second connecting rod, all the second connecting rods The connecting rod rotates with the first connecting rod to achieve the raising or lowering of the movable plate; when the height of the device is adjusted, the handle can be stopped, and then the experimenter can control the extension and retraction of the telescopic rod through the switch. The inclination of the workbench can be adjusted through this structure. During the experiment, the required anatomical tools can be placed on the tool racks on both sides of the movable plate. When the tools are not in use, the tool racks on both sides can be pushed back into the rectangular grooves on both sides of the movable plate to avoid infection of the tools to a certain extent; when the experiment is over and the workbench needs to be cleaned, the telescopic rod is adjusted to a certain inclination of the workbench, and then the faucet is turned on to clean the workbench, and the dirty water will be discharged through the diversion groove and the drain pipe.
