Description

Technical Field

[0001] The invention relates to the technical field of medical research and medical equipment, and in particular to an adjustable operating table suitable for a brain stereotaxic instrument for mice and rats. Background Art

[0002] Stereotaxic apparatus, also known as brain fixation device, uses a three-dimensional coordinate system defined by signs on the outside of the skull or other reference points to determine the location of certain subcortical neural structures, so as to conduct targeted stimulation, destruction, drug injection, and potential guidance research under non-direct exposure. Animal brain stereotaxic apparatus is an important research device in the fields of neuroanatomy, neurophysiology, neuropharmacology, and neurosurgery. It is used for targeted injection, stimulation, destruction, and potential guidance of neural structures. It can be used to establish animal models of cerebral hemorrhage, Parkinson's disease, epilepsy, brain tumors, learning and memory, brain neural stem cell transplantation, cerebral ischemia, and other studies.

[0003] At present, commonly used stereotaxic instruments for rats and mice generally have incisor hooks and ear bars on both sides. The incisors of rats and mice are fixed on the incisor hooks, and the ear bars on both sides are aligned with the ear canals of rats and mice. The heads of rats and mice are fixed using the three-point positioning principle to facilitate subsequent research. However, there are the following shortcomings when using stereotaxic instruments to position rats and mice:

[0004] (1) When fixing rats or mice, two people are required to work together, one person holds the rat or mouse to adjust the height and position, and the other person adjusts the ear bar to align it with the ear canal of the rat or mouse. This operation is cumbersome and consumes unnecessary manpower.

[0005] (2) The current fixation method only fixes the ears and mouth, and the whole body is not fixed or the body is suspended in the air, which may cause the fixation to loosen during the experiment and affect the experimental process;

During the experiment, the trunk of the anesthetized rat or mouse is placed on the first operating table 10 and the head is placed on the second operating table 20, the first lifting mechanism 40 is used to adjust the height of the first operating table 10, and the second lifting mechanism 50 is used to adjust the height of the second operating table 20, and only one person is needed to complete the positioning operation, saving manpower; the height of the first operating table 10 and the second operating table 20 can be adjusted independently, that is, the position of the trunk or head of the rat or mouse can be independently adjusted within the allowed range, and the adjustment flexibility is strong.

[0038] Please refer to Figure 1 , Figure 3 and Figure 5 The first lifting mechanism 40 includes a first active rod 41, a first driven rod 42 and a first adjusting knob 43. The middle part of the first active rod 41 is hinged to the middle part of the first driven rod 42. The first active rod 41 and the first driven rod 42 are in an X shape. The upper end of the first active rod 41 is hinged to the side of the first operating table 10, and the lower end of the first active rod 41 is hinged to the side of the bottom plate 30. The first adjusting knob 43 is fixed to the outer side of the lower end of the first active rod 41; a first slide groove 11 is provided on the side of the first operating table 10, and a second slide groove 31 is correspondingly provided on the side of the bottom plate 30. The upper end of the first driven rod 42 is embedded in the first slide groove 11, and the lower end of the first driven rod 42 is embedded in the second slide groove 31. The upper end of the first driven rod 42 can slide in the first slide groove 11, and the lower end of the first driven rod 42 can slide in the second slide groove 31. The height adjustment process of the first operating platform 10 is as follows: when the first adjusting knob 43 is rotated, the first active rod 41 rotates, and the angle between the first active rod 41 and the base plate 30 changes. Since the first driven rod 42 is hinged to the first active rod 41, the upper end of the first driven rod 42 can slide in the first slide groove 11, and the lower end of the first driven rod 42 can slide in the second slide groove 31, so the first driven rod 42 also rotates at the same time, and the angle between the first driven rod 42 and the base plate 30 changes, thereby changing the height between the first operating platform 10 and the base plate 30 to achieve the purpose of height adjustment; in Example 1 of the present invention, rotating the first adjusting knob 43 clockwise can lower the height of the first operating platform 10, and rotating the first adjusting knob 43 counterclockwise can increase the height of the first operating platform 10.

The upper end of the second driven rod 52 can slide in the third slide groove 21, and the lower end of the second driven rod 52 can slide in the fourth slide groove 32. The height adjustment process of the second operating platform 20 is similar to the height adjustment process of the first operating platform 10: when the second adjusting knob 53 is rotated, the second active rod 51 rotates, and the angle between the second active rod 51 and the base plate 30 changes. Since the second driven rod 52 is hinged to the second active rod 51, the upper end of the second driven rod 52 can slide in the third slide groove 21, and the lower end of the second driven rod 52 can slide in the fourth slide groove 32, so the second driven rod 52 also rotates accordingly, and the angle between the second driven rod 52 and the base plate 30 changes, thereby changing the height between the second operating platform 20 and the base plate 30 to achieve the purpose of height adjustment; in Example 1 of the present invention, rotating the second adjusting knob 53 clockwise can lower the height of the second operating platform 20, and rotating the second adjusting knob 53 counterclockwise can increase the height of the second operating platform 20.
