Dissecting table for cervical vertebra surgeries of medium and small sized animals

Abstract

The invention relates to a dissecting table for cervical vertebra surgeries of medium and small sized animals. The dissecting table comprises a worktable body, a head rack and a foot rack, wherein the head rack is connected with the worktable body through a hinge shaft, a semi-cylindrical bolster is arranged on the head rack, a screw is arranged under the bolster and is embedded into a bolster sliding groove and used for adjusting and fixing the position of the bolster, a limb binding band for fixing the corresponding limb of an experimental animal is installed at the four corners of the worktable body respectively, and the four limb binding bands are adjusted or fixed to four diagonal binding band sliding grooves through screws. The dissecting table has the advantages that when the dissecting table is used for animal dissection, the head of the experimental animal can be effectively placed to enable the cervical vertebra of the experimental animal to be fully exposed; the placement angle of the head of the experimental animal can be adjusted according to the size and shape of the experimental animal; the head of the experimental animal can be firmly fixed, automatic retraction of the neck skin of the experimental animal can be achieved, labors can be saved, and the surgical efficiency can be improved.

Description

【Technical field】 [0001] The invention relates to the technical field of experimental animal surgical tools, in particular to a dissection table for cervical spine surgery of small and medium-sized animals. 【Background technique】 [0002] A large number of animal experiments on cervical spine surgery have been carried out. When performing cervical spine surgery on small and medium-sized experimental animals such as rabbits, rats, and small dogs, it is necessary to adjust the position of the animal's head and cervical spine with individualized angles and fix them, so as to facilitate the operator's operation, reduce the pressure on the assistant, and improve the operation efficiency. An operating table that does not meet the requirements will increase the operation time, the number of turnovers and the probability of contamination. [0003] At present, the following problems exist in the existing operating consoles: 1. The existing experimental animal operating consoles are ...

AI Technical Summary

Problems solved by technology

An unqualified operating table will increase the operation time, the number of turnovers and the probability of contamination

[0003] At present, the following problems exist in the existing operating consoles: 1. The existing experimental animal operating consoles are relatively general models, and most of them are used for chest, abdomen and limb operations of animals in the supine position, and there is no special operation for cervical spine surgery. tower

2. The existing experimental animal operating table cannot fix the head of the animal well

Most operating tables only have one column at the head end, and the single-directional fixation makes the animal break free from the fixed line when it is stimulated by surgery after anesthesia.

Some consoles have a fixed head frame, and it is also impossible to bind and fix different animals

3. The existing operating table is not equipped with a device to help fix the incision hook. The skin of the neck of the experimental animal is soft. After the incision, an assistant needs to pull the skin hook continuously, which cannot free up hands to help the operator.

[0004] The utility model patent document "an animal operating table" with the application number CN201520157195 and the announcement number CN204521040U shows a new type of operating table that irradiates the light source to the position required in the operation. The cervical spine cannot be effectively exposed and fixed, and the self-contained power supply is easily contaminated by blood and flushing fluid produced during the experiment, causing electric shock hazards; the utility model patent document "Animal Operating Table" with the application number CN201520085754 and the announcement number CN204484394U Although the appliance solves the problem of fixing animal limbs, it is not a special appliance for cervical spine surgery; the utility model patent document "An Experimental Animal Operating Table" with the application number CN201220704397 and the announcement number CN203138739U tries to solve the problem of animal limbs, heads, etc. Intraoperative fixation of various parts, but it cannot solve the problem that animals of different sizes and shapes need to place their heads at different angles

[0005] In summary, there is currently a lack of a method that can effectively place the head of experimental animals, fully expose the cervical spine, adjust the angle of head placement according to different sizes and types of animals, and can firmly fix the head, while achieving neck skin. An operating table that automatically retracts, eases the workload of assistants and improves surgical efficiency
