detailed description

Below in conjunction with specific embodiment and accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, the utility model is a fixing frame for fixing small experimental animals for eye experiments. Its main structure mainly includes three parts: the lower part is a fixing clip, the upper part is a fixing table, the middle part is a universally rotatable and large Angled swivel device.

The fixed table 1 is a flat plate whose front end is in the shape of an isosceles triangle. Two semicircular card supports 2 are arranged symmetrically on the waist of the isosceles triangle on the upper surface of the fixed table. It is made of telescopic material, and adhesive sheets 4 are arranged at both ends.

The rotating device comprises a rotating ball 5 and a ball seat 6 tightly half-wrapping its outside. The rotating ball can rotate freely in the ball seat, and the ball seat can be fixed on the rotating ball without sliding simultaneously. The lower surface of the front end of the fixed table is connected to the ball seat of the rotating device through the first connecting rod 7, and the rotating ball of the rotating device is connected to the fixing clip through the second connecting rod 8.

The fixing clip includes two clamping handles 9 and a strong elastic clip 10 connecting the clamping handles. The clamping handles can be opened at a large angle. The inner side of the clamping handle is provided with a non-slip rubber pad 11 whose surface is in the shape of fine teeth.

According to the different sizes of the experimental animals, the fixed table has different corresponding dimensions.

Before using ophthalmic clinical instruments to observe and operate the eyes of small experimental animals, open the clamp handle of the fixing clip, and clamp the fixing frame vertically on the jaw rest of the ophthalmic instrument through the elastic force of the elastic clip. The tooth-shaped non-slip rubber pad on the inner side of the distal end of the clamping handle can make the fixing frame stably fixed on the chin rest of the ophthalmic instrument. The experimenter can adjust the front and rear positions of the fixed platform by slightly adjusting the front and rear tilt angles of the clips as needed. Place the anesthetized experimental animal belly down on the fixed platform, the neck of the experimental animal is located between the brackets on the fixed platform, the nose of the experimental animal is located at the tip of the isosceles triangle at the front of the fixed platform, and the restraint belt is looped around Experimental animal body to immobilize the experimental animal. When observing and operating the eyes of experimental animals, the horizontal rotation of the fixed table to the left or right can make the experimental animals in a lateral position, so that the left or right eyes of the experimental animals are exposed in front of the ophthalmic instruments. When the fixed table is in the side position, the ball seat and the ball head cooperate to rotate in multiple directions at a large angle, so as to observe and operate the eyes in multiple directions. The body of the experimental animal is fixed by a restraint belt adhesive sheet, and the head is fixed by a neck collar. The movement of experimental animals between different ophthalmic clinical instruments only needs to move the fixed frame as a whole, and the experimental animals can be taken out of the fixed frame by loosening the Velcro after the experiment. The fixing frame is made of plastic material, which can be cleaned and disinfected conveniently.

The specific implementation above is just an example, and it is for those skilled in the art to better understand this patent, and it cannot be understood as a limitation on the scope of this patent; as long as it is any equivalent change made according to the spirit disclosed by this patent or modifications, all fall within the scope of this patent.
