[0002] Animal experiments refer to scientific research conducted in a laboratory using animals to gain new knowledge or solve specific problems in fields such as biology and medicine. Animal experiments must be conducted by trained personnel with research degrees or professional technical skills, or under their guidance. In animal experiments using mice as subjects, surgery is often required to obtain more effective data. Biomedical experiments often require platforms for constructing intracranial in situ tumor models with anesthesia and temperature control capabilities.

This invention can uniformly apply force to fix the entire body of the mouse, ensuring that no local part of the mouse is subjected to force during surgery, thus reducing the risk of injury and improving the success rate of the surgery. It is equipped with an ultrasound stimulation module, a physiological signal acquisition module, and an electron microscope magnification imaging module, meeting the needs of transcranial ultrasound stimulation experiments in mice.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 5An operational platform for constructing an intracranial in situ tumor model with thermal insulation function includes an operational platform body 1, a tumor model display mechanism 2 fixed to the operational platform body 1, and a vacuum device 3. A thermal insulation cover 4 is hinged to one side of the operational platform body 1, and the thermal insulation cover 4 has an internal mounting groove 41. A vacuum hole for use with the vacuum device 3 is also provided inside the operational platform body 1. Closing the thermal insulation cover 4 utilizes the thermal insulation material inside the cover 4 to maintain the model in a suitable temperature environment. Activating the vacuum device: The vacuum hole inside the operational platform body 1 is connected to the vacuum device 3. Activating the vacuum device 3 further stabilizes the model and prevents movement or deformation during operation. The operational platform body 1, the tumor model display mechanism 2, and the vacuum device 3 are all conventional technologies known to the public in the prior art; therefore, their specific structural composition and working principle will not be described in detail here.

[0020] To improve the experimental environment, a disinfection device 5 is installed inside the insulation cover 4. The disinfection device 5 includes a frame 501, an infusion structure, a swing structure, and a drive structure 508. The infusion structure consists of a storage tank 502, an infusion tube 503, and a nozzle 504. The nozzle 504 is mounted on the swing structure, and the angle of the nozzle 504 is adjusted by driving the swing structure through the drive structure 508. The two ends of the infusion tube 503 are connected to the storage tank 502 and the nozzle 504, respectively. The infusion tube 503 is a flexible tube, and a small submersible pump is installed inside the storage tank 502.

[0021] Specifically, the swing structure includes a mounting shaft 506 and a swing frame 507. The swing frame 507 is fixed to the outer surface of the mounting shaft 506, and both the upper and lower ends of the mounting shaft 506 are connected to bearings inside the frame 501. Both the swing frame 507 and the frame 501 are U-shaped, with their concave surfaces facing each other. There are two frames 501, and a connecting plate 505 is welded between them. The liquid storage tank 502 is fixed to the back of the two frames 501. Through the cooperation of the swing structure and the drive structure 508, the nozzle 504 can be adjusted at multiple angles, ensuring that the disinfectant can evenly and comprehensively cover all corners of the operating platform body 1. This design greatly improves the efficiency and effectiveness of disinfection and avoids blind spots.

[0022] To improve the driving range, in this embodiment, the driving structure 508 includes a dual-axis motor 5081 fixed to the back of the connecting plate 505, a turntable 5082 and a stirring rod 5086 fixed to the two output shafts of the dual-axis motor 5081, a connecting shaft 5083 fixed to the front of the turntable 5082, a swing arm 5084 fixed to the other end of the connecting shaft 5083, and a connecting seat 5085 rotatably mounted on the bottom side of the swing arm 5084. Connecting rods 509 are hinged to both sides of the connecting seat 5085. The driving structure 508 uses a dual-axis motor 5081. One output shaft drives the turntable 5082 and the connecting shaft 5083, which in turn drives the swing frame 507 to swing via the swing arm 5084 and the connecting rods 509. The other output shaft drives the stirring rod 5086 to stir the disinfectant in the storage tank 502, preventing sedimentation. This design not only improves driving efficiency but also ensures the uniformity of the disinfectant.

[0023] Specifically, there are two swing frames 507. Each swing frame 507 has a connecting rod 5091 fixed to its inner side, hinged to two connecting rods 509. To improve the spraying effect of the nozzle 504, a sliding seat 510 for fixing the nozzle 504 is detachably installed on the swing frame 507. A groove 511 is provided inside the swing frame 507, and the sliding seat 510 is slidably installed within the groove 511. Both the swing frame 507 and the sliding seat 510 have adjustment holes 512 inside, and a positioning rod 513 is inserted into each adjustment hole 512. There are multiple adjustment holes 512 on the swing frame 507. The adjustment holes 512 on the swing frame 507 communicate with the groove 511. The detachable sliding seat 510, the groove 511, and the adjustment holes 512 on the swing frame 507 allow for convenient adjustment of the nozzle 504's position. Researchers can precisely set the spray position of the nozzles as needed to meet the disinfection requirements under different experimental conditions.

[0024] The working principle of the above embodiments is as follows: When disinfection is required, the disinfection equipment 5 is activated. A small submersible pump delivers the disinfectant solution in the storage tank 502 to the nozzle 504 through the infusion pipe 503. The dual-axis motor 5081 is activated, and one output shaft drives the turntable 5082 and the connecting shaft 5083 to rotate. This, in turn, pushes the swing frame 507 to swing around the mounting shaft 506 through the swing arm 5084 and the connecting rod 509, thereby adjusting the angle of the nozzle 504. The stirring rod 5086 on the other output shaft can be used to stir the disinfectant solution in the storage tank 502 to prevent sedimentation. The nozzle 504 is then turned on to spray disinfectant, which evenly covers the tumor model and its surrounding area, achieving the purpose of disinfection.

[0025] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections. Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
