Technical Field
The invention relates to a surgical medical auxiliary instrument, in particular to an automatic cooling system for a medical neurosurgery region.
Background
The bipolar coagulator is the most common hemostatic tool in neurosurgery, has been widely applied to all parts of the central nervous system along with the development of neurosurgery, and becomes an important hemostatic means essential for neurosurgery. However, the use of the bipolar electrocoagulator may produce certain thermal effects on peripheral nerve cells and nerve tissues, which may cause a wide range of damage, known as thermal damage, which may result in loss of nerve function, particularly in some critical blood vessels, functional areas, brain stem, spinal cord, etc., which may sometimes be fatal.
Clinically, in order to reduce the thermal damage caused by the use of the bipolar electrocoagulator, two treatment schemes are mainly adopted:
1. the operating physician is used to lower the temperature of the operating area by flushing normal temperature normal saline solution to the operating area (the operating area on the patient body) at random.
2. Some bipolar electrocoagulators are provided with a continuous water dropping system, and a certain amount of physiological saline can be dropped to a region to be stopped bleeding when the bipolar electrocoagulator is used.
The first scheme depends on the attention of a doctor, the randomness is too large, the time for flushing and cooling and the physiological saline amount for flushing are difficult to accurately control, the flushing time interval is too long, the flushing amount is insufficient, the cooling purpose cannot be achieved, and the nerve thermal injury is easily caused; too frequent flushing and too much flushing amount easily affect the visual field of the doctor of the main knife.
The second proposal adopts continuous dripping, avoids human factors, but is difficult to balance the relation between the dripping water quantity and the nerve protection, if the dripping water quantity is too large, the possibility of nerve thermal injury is reduced, the hemostasis efficiency is affected, and the operation time is prolonged; when the water volume is too small, the possibility of nerve thermal injury is high, eschar adhesion can occur on the bipolar tip, and the hemostatic efficiency is also influenced.
Therefore, the two processing schemes in the prior art have the problems of inaccuracy and intelligence.

Detailed Description
The invention aims to provide an automatic cooling system for a medical neurosurgery operation area, which realizes temperature monitoring and automatic flushing and cooling of the operation area, thereby solving the problems of inaccuracy and intelligence in the treatment scheme for reducing thermal injury caused by use of a bipolar electric condenser in the prior art. The core idea is as follows: the temperature sensor module is used for acquiring the temperature value of the operation area in real time, transmitting the temperature value to the control module, comparing the actual temperature value of the operation area with a set temperature threshold value by the control module, automatically triggering and controlling the lavage device to wash the operation area to reduce the temperature of the operation area when a trigger condition is met, and automatically controlling to stop washing when the temperature of the operation area is reduced to be lower than the set temperature threshold value.
In a specific implementation, as shown in fig. 1, the automatic cooling system for a neurosurgical operation area in the invention comprises a control module, a temperature sensor module and an irrigation module, wherein the temperature sensor module and the irrigation module are both electrically connected with the control module.
