Description

Technical Field

[0001] The utility model relates to the technical field of experimental pigs, in particular to an abdominal expansion device used for experimental pig dissection. Background Art

[0002] Experimental pigs refer to pigs that are artificially bred, have controlled pathogenic microorganisms and parasites they carry, have a clear genetic background or source, and are used for scientific research, teaching, production, inspection and other scientific experiments. With the continuous development of research on the biological characteristics of pigs, it has been found that pigs are very similar to humans in many biological indicators such as anatomy, tissue, physiology and biochemistry. They are considered to be the most suitable experimental animal model for studying diseases. They are economical and practical and overcome the shortage of the same organs. When dissecting experimental pigs, an abdominal expander is needed to expand the abdomen of the experimental pig so that its internal organs can be dissected.

[0003] However, most of the existing abdominal expansion devices are manually operated with tools such as clamps to pull the abdomen of the experimental pig with a slit to both sides. It is impossible to quickly expand the abdomen of the experimental pig to both sides independently according to the anatomical needs. The manual expansion method is very laborious and requires the cooperation of multiple people to complete, which will directly affect the normal anatomical work of the experimental personnel on the experimental pig. Utility Model Content

[0007] Preferably, the auxiliary component includes a movable frame inserted laterally on both sides of the bar frame, an auxiliary rod is rotatably installed at one end of the movable frame that is close to each other, and the auxiliary rod is rotatably installed on the toggle frame at one end away from the movable frame, and a bar tooth plate is fixedly connected to one end of the movable frame away from the auxiliary rod, and a fixed frame is fixedly connected to the front side of the bar frame, and a motor is fixedly connected to the fixed frame, and the output shaft of the motor is fixedly connected to a gear used in conjunction with the bar tooth plate.

[0008] Preferably, the bottoms of the shifting frames that are away from each other are fixedly connected with a transverse plate, and the sides of the transverse plates that are close to each other are fixedly connected with a blocking rod.

[0009] Preferably, the front sides of the top and bottom of the bar frame are fixedly connected with mounting frames, the sides of the bar-shaped tooth plates away from each other are fixedly connected with slide plates, and the mounting frames are provided with slideways for use with the slide plates.

[0010] Preferably, the bottoms of the shifting frames that are away from each other are in an inclined structure.

[0011] Preferably, two sets of triangular support plates are symmetrically fixedly connected to the lifting frame along the left-right direction.

[0012] Preferably, the bottoms of the shifting frames are close to each other and fit together.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The abdominal expansion device for experimental pig dissection can drive two groups of movable frames to move synchronously in opposite directions by setting auxiliary components, using a motor to provide a driving source, and utilizing the meshing of gears and bar-shaped toothed plates.

By setting the auxiliary component, the toggle frame 3 whose bottom extends outward autonomously can quickly expand the abdomen of the experimental pig that has been cut open to both sides, so that the user can dissect the internal organs of the experimental pig according to the experimental needs, which is more labor-saving and convenient than the manual expansion method.

[0022] Embodiment 2

[0023] Improved on the basis of Example 1: An abdominal expansion device for experimental pig dissection, comprising a bar frame 1, a lifting frame 2 is fixedly connected to the back of the bar frame 1, two sets of triangular support plates are symmetrically fixedly connected to the lifting frame 2 along the left and right directions, the design of the triangular support plates can reinforce the lifting frame 2 and improve its overall strength, a control switch 15 is arranged on the back of the lifting frame 2, both sides of the front and back sides of the inner cavity of the bar frame 1 are rotatably equipped with docking shafts 16, the ends of the front and rear sets of docking shafts 16 close to each other are fixedly connected to the toggle frame 3, and the toggle frame 3 is moved away from each other. The bottom is fixedly connected with a transverse plate 12, and a blocking rod 13 is fixedly connected to one side of the transverse plates 12 close to each other. By setting the transverse plate 12 and the blocking rod 13, the exploration depth of the toggle frame 3 can be controlled to ensure that the toggle frame 3 will not get stuck due to excessive exploration and affect the normal operation of the device. The bottoms of the toggle frames 3 that are far away from each other are inclined. The toggle frames 3 with an inclined structure are convenient for inserting the toggle frames 3 into the pre-cut gaps. The bottoms of the toggle frames 3 that are close to each other fit together. The fitting design can ensure that the toggle frames 3 are stably inserted. The bar frame 1 is provided with a toggle frame 1 that fits the toggle frame 3. The auxiliary components used in conjunction with the moving frame 3 include a moving frame 4 inserted laterally on both sides of the bar frame 1, an auxiliary rod 5 is rotatably installed at one end of the moving frame 4 close to each other, and the auxiliary rod 5 is rotatably installed on the toggle frame 3 at one end of the moving frame 4 away from the auxiliary rod 5, and a strip tooth plate 6 is fixedly connected to the end of the moving frame 4 away from the auxiliary rod 5. The front sides of the top and bottom of the bar frame 1 are fixedly connected to a mounting frame 9, and a slide plate 10 is fixedly connected to the side of the strip tooth plate 6 away from each other. A slideway 11 used in conjunction with the slide plate 10 is provided on the mounting frame 9, and the mounting frame 9, the slide plate 10 and The design of the slide 11 can limit the sliding of the bar tooth plate 6, thereby improving its stability during movement. A fixing frame 14 is fixedly connected to the front of the bar frame 1, and a motor 7 is fixedly connected to the fixing frame 14. The output shaft of the motor 7 is fixedly connected to a gear 8 used in conjunction with the bar tooth plate 6.

Compared with the manual opening method, it is more labor-saving and convenient.

[0024] In the utility model, the user cuts a slit in the abdomen of the experimental pig in advance, and then directly inserts the bottom end of the toggle frame 3 into the slit. At this time, the cross plate 12 and the blocking rod 13 can control the downward depth of the toggle frame 3. Then the user turns on the motor 7 by controlling the switch 15. At this time, the motor 7 drives the gear 8 to rotate. At this time, the engagement of the gear 8 and the bar gear plate 6 drives the two groups of bar gear plates 6 to move synchronously in the opposite direction, and then the two groups of moving frames 4 can be driven to move synchronously in the opposite direction, so that the position of the auxiliary rod 5 is changed synchronously. Since the toggle frame 3 is rotatable with the assistance of the docking shaft 16, the auxiliary rod 5 will push the toggle frame 3 to swing synchronously in the opposite direction, so that the user can use the toggle frame 3 whose bottom expands outward autonomously to quickly open the opened abdomen of the experimental pig to both sides, so that the user can dissect the internal organs of the experimental pig according to the experimental needs. Compared with the manual opening method, it is more labor-saving and convenient.
