DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large-animal operating table suitable for performing surgery (especially brain surgery) on large animals such as cows and horses under general anesthesia.

[0002]

2. Description of the Related Art Conventionally, when operating large livestock such as cows and horses under general anesthesia, large animal operating table equipment for keeping them in a lying position or a supine position has been used. When performing general anesthesia treatment on an adult cattle weighing about 600 kg using this large animal operating table equipment, at least 5
More people are required, and there is a high risk of injury to the politician when the cow is rampaged.

Further, when an adult cow is subjected to general anesthesia in a lying position for a long time, the weight of the cow itself may cause nerve compression on the hind limb in the lying position, making the cow unable to stand up after the operation. In addition, general anesthesia has the effect of suppressing ruminal movement in cattle, causing ruminal bloating and increasing the possibility of aspiration of ruminal fluid. As described above, it is difficult to perform general anesthesia for a long time with the currently used recumbent large animal operating table equipment. In addition, at present, the method of cattle brain surgery is not well established, and no dedicated operating table equipment has been developed.

[0004] When performing brain surgery, monitoring that is particularly important is management of cerebral pressure (intracranial pressure). A sudden increase in brain pressure associated with brain surgery can be fatal, and control of brain pressure has a significant effect on the prognosis of surgery. However, for cattle, a useful brain pressure measurement method has not yet been developed, and there has been little information on brain surgery. In view of this point, the inventor of the present application has conducted intensive research and developed an epidural pressure measurement method as a method for measuring brain pressure in cows, and using this method, compared changes in brain pressure in cattle standing and lying down. Then, FIG. 4 (A),
As shown in (B), when the cow was kept in the lying position, it was found that the brain pressure rapidly increased.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to operate a large animal such as a cow under general anesthesia (particularly brain surgery). Surgery) can be performed by a relatively small number of people with a relatively small number of people, making it easy to take a position suitable for surgery on large animals such as cows, and keeping the head reasonably and reliably, and thus under general anesthesia. It is an object of the present invention to provide a large animal operating table equipment capable of performing surgery safely for a long time.
