Description

An experimental animal operation dissection table with adjustable head frame angle

technical field

The utility model relates to the technical field of experimental animal surgical instruments, in particular to an experimental animal surgical dissection table which can adjust the angle of a head frame.

Background technique

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.

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. Cervical spine surgery has very high requirements for body position. It is required to adopt a posture with a raised neck and an excessively tilted head. Unsuitable exposure of the surgical site will greatly increase the amount of bleeding during the operation, the operation time, and reduce the quality of the operation and the survival of experimental animals. Rate (Min Yue. Design and use of a new type of cervical spine fixation pillow [J]. China Health Standard Management, 2015, 13:24-25.). 2. The existing operating table for experimental animals cannot fix the animal's head well. Most of the operating tables have only one column at the head end, and the single-direction fixation makes the animal break free from the fixed line when it is stimulated by surgery and moves its head after anesthesia. Some operating tables have a fixed head frame, which also cannot be tied and fixed for 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. Cervical spine surgery often requires assistants to help pass instruments, rinse, etc.

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. The intraoperative fixation of various parts cannot solve the problem that animals of different sizes and shapes need to place their heads at different angles. 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.

The purpose of this utility model is to provide a kind of experimental animal operation dissection table which can adjust the angle of the head frame in view of the problems existing in the prior art described above.

In order to achieve the above object, the technical solution adopted by the utility model is: an experimental animal surgical dissection table with adjustable head frame angle, including a workbench main body, a head frame and a tripod, and a loose-leaf shaft is passed between the head frame and the work table main body. connected, the head frame is provided with a semi-cylindrical pillow, and a screw is set under the pillow, which is embedded in the pillow chute, and is used to adjust and fix the position of the pillow. Limb straps used to fix the limbs of experimental animals. The limb straps are adjusted or fixed by screws on four oblique strap chutes.

The angle between the main body of the workbench and the head frame can be adjusted or fixed by a loose-leaf shaft, and the adjustable range of the angle is between -30° and 30°.

Both sides of the head frame are respectively provided with neck skin retractor columns along the axial direction of the pillow, which are used for pulling the pulling wires for pulling the neck skin of experimental animals during the fixation operation.

The top edge of the head frame is provided with three hanging wire fixing devices, and the hanging wires are respectively connected to the hanging wire fixing devices during the operation.

The utility model has the advantages that:

1. When used for animal dissection, the dissection table of the present invention can effectively place the head of the experimental animal, fully expose the cervical spine of the experimental animal, and facilitate operation.
