[0026] 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.

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, a multifunctional operating table for small animals includes a hollow tabletop 1, a solid collection base 2, a rotating shaft 3, an angle adjustment and locking mechanism, multiple limb fixation components 8, a heating device, and a heating control panel 7.

[0029] The hollowed-out table surface 1 has an array of positioning holes 101, with a spacing of 5 mm between these positioning holes 101. This evenly distributed positioning hole 101 design allows the surgeon to flexibly adjust the fixed position according to the size and type of small animal, improving surgical precision.

[0030] A solid collection tray 2 is positioned below the perforated tabletop 1 to collect fluids and tissue fragments generated during surgery, preventing contamination of the surgical area and facilitating cleaning. The solid collection tray 2 is a square tray with a projected area larger than that of the perforated tabletop 1, ensuring complete collection of fluids dripping from the perforated tabletop 1 and preventing contamination of the surgical environment.

[0031] A pivot 3 connects one end of the hollow platform 1 to the solid collection base 2, allowing the hollow platform 1 to rotate relative to the solid collection base 2. The design of the pivot 3 allows the hollow platform 1 to rotate 180° around the pivot 3 and be stored inside the solid collection base 2, significantly saving storage space and facilitating carrying and storage. The pivot 3 is made of high-strength material to ensure stability and durability during rotation.

[0032] The angle adjustment and locking mechanism includes a support rod 4, a slider, a slot mechanism 5 located on the side of the hollowed-out table surface 1, and a linear drive assembly 6 mounted on the solid collection base 2. The slot mechanism 5 has multiple angle settings, including 0°, 15°, 30°, 45°, 60°, 75°, and 90°, allowing the operator to precisely adjust the table surface tilt angle according to surgical needs. The linear drive assembly 6 consists of a gear and rack, with the gear integrating a manual knob. By rotating the manual knob, the gear drives the rack, which in turn moves the slider, thereby changing the position of the support rod 4 and adjusting the tilt angle of the hollowed-out table surface 1. The tilt angle adjustment range of the hollowed-out table surface 1 is from 0° to 90°, meeting the needs of different surgical postures.

[0033] Specifically, the linear drive assembly 6 is preferably a gear-rack mechanism, but other mechanisms with the same linear drive function, such as a lead screw and nut mechanism, can also be used.

[0034] Multiple limb fixation pieces 8 are detachably installed in the positioning holes 101 of the hollowed-out tabletop 1. The limb fixation pieces 8 are magnetic quick-release screws with elastic pads at their ends. The magnetic design allows the fixation pieces to be firmly attached to the metal tabletop, while the quick-release structure facilitates position adjustment; the elastic pads at the ends gently fix the limbs of small animals, avoiding additional injury, while providing appropriate pressure to ensure a secure fixation effect.

[0035] The heating device is embedded in the perforated table surface 1 to maintain the body temperature of the small animal during surgery and prevent low temperature from adversely affecting the operation. The heating device adopts a uniformly distributed heating wire design to ensure uniform temperature distribution on the table surface and avoid local overheating or insufficient temperature.

[0036] The heating control panel 7 is electrically connected to the embedded heating device via a cable, which is embedded in the rotating shaft 3 structure. The control panel can be placed in a convenient location next to the operating table. The control panel is equipped with a temperature adjustment knob and a digital display screen. The operator can precisely adjust the table surface temperature according to the size of different small animals and the needs of the surgery. The temperature control range is from room temperature to 40℃, with a control accuracy of ±0.5℃.

[0037] During operation, the operator first adjusts the tilt angle of the perforated tabletop 1 according to the animal's size. By turning the manual knob to drive the gear and rack mechanism, the support rod 4 is fixed at the appropriate angle position in the slot mechanism 5. Then, the limb fixation piece 8 is inserted into the corresponding positioning hole 101, and the animal's limb is gently fixed using magnetic quick-release screws and elastic pads. At the same time, the appropriate tabletop temperature is set through the heating control panel 7 to ensure that the animal maintains a normal body temperature during the surgery. After the surgery, the perforated tabletop 1 can be rotated 180° and stored in the solid collection tray 2 for easy cleaning and storage.

[0038] In a preferred embodiment, the perforated tabletop 1 is made of medical-grade stainless steel, which has excellent corrosion resistance and easy-to-clean properties; the solid collection base 2 is made of high-strength engineering plastic, which is lightweight and durable; the heating device has a maximum power of 60W and can raise the tabletop temperature from room temperature to the set temperature within 5 minutes.

[0039] This multifunctional operating table for small animals meets the needs of different types of small animal surgeries through its hollow design and multi-angle adjustment function; detachable limb fixation devices allow for flexible fixation of animals of different sizes; a built-in heating system ensures stable animal body temperature during surgery; and a foldable storage design improves the portability and storage efficiency of the equipment. The overall design fully considers the special needs of small animal surgery, significantly improving the convenience and precision of surgical operations.

[0040] Example 2

[0041] like Figure 1 and Figure 2As shown, the small animal multifunctional operating table in Example 1 is used as follows: Taking mouse liver vein ligation surgery as an example. Step 1: Before starting, thoroughly disinfect the perforated operating table with alcohol and preheat the operating table to 37°C; Step 2: Determine the position of the limb fixation screws according to the size of the mouse, and anesthetize and fix the mouse on the perforated operating table; Step 3: Adjust the angle of the operating table to 30° or 45° through the rotating shaft 3, and lock the support rod 4 through the knob to ensure the best surgical field of vision; Step 4: Perform the surgery, and waste fluid and blood will automatically flow into the lower chassis; Step 5: After the surgery, turn off the heating device, clean and disinfect the chassis and operating table with alcohol, check the status of the locking mechanism, and air dry in a ventilated place.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
