[0002] Neurosurgery is a branch of surgery. It is a high-level, sophisticated and cutting-edge discipline that uses unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, and its related ancillary structures, such as the skull, scalp, cerebral blood vessels and meninges, as well as injuries, inflammation, tumors, malformations and certain genetic metabolic disorders or functional disorders, such as the causes and pathogenesis of epilepsy, Parkinson's disease, neuralgia, etc., and explores new diagnosis, treatment and prevention technologies. Neurosurgery is mainly responsible for diseases of the brain, spinal cord and other nervous systems caused by trauma, such as life-threatening cerebral hemorrhage, brain trauma caused by car accidents, or brain tumor compression requiring surgical treatment.

[0003] Neurosurgery is mainly responsible for diseases of the brain, spinal cord and other nervous systems caused by trauma, such as life-threatening cerebral hemorrhage, brain trauma caused by car accidents, or brain tumor compression requiring surgical treatment. In neurosurgery, suction tubes are the most basic and extremely important surgical instruments, which can remove bleeding, exudates, pus, and contents of chest organs during surgery to make the surgery clear and reduce the chance of contamination. However, existing suction tube devices are cumbersome to operate, and cannot manually and accurately control the suction force to absorb dirty blood.

[0013] Working principle: When in use, if the external threaded tank body is filled with cleaning liquid, first open the solenoid valve through the magnetic valve switch, and then move the buckle rod to the left. The movement of the buckle rod to the left drives the lower fixed bar to move to the left. The movement of the lower fixed bar can make the upper fixed bar move to the right through the gear and rack, so that the push rod pushes the piston. When the force is stopped, the buckle rod will return to its original position due to the spring. In the process of returning to its original position, the cleaning liquid inside the external threaded tank body will enter the sealing tube due to the siphon principle. In this process, blocking the pipe head will have a better effect. Then close the solenoid valve and operate the buckle rod again to spray out the cleaning liquid. Similarly, if the external threaded tank body is used to store waste liquid, you only need to remove the extension tube to attract the waste liquid. The operation is simple and controllable.

It has multiple functions, simple operation, and is convenient for practical use.

[0015] 2. The present invention provides a neurosurgical aspirator with an electrocoagulation function. When in use, the device can install or replace the front structure by rotating the internal threaded tube. The operation is simple and the cleaning and maintenance are more convenient.

[0016] 3. The present invention provides a neurosurgical aspirator with an electrocoagulation function. When the device is in use, the suction force of the device and the flow rate of the spraying cleaning fluid can be accurately adjusted by moving the buckle rod left and right, thereby increasing safety and saving resources.

[0017] 4. The present invention provides a neurosurgical aspirator with an electrocoagulation function. When in use, the device can slide in a limiting slide groove through a limiting slider, thereby making the upper fixing bar more stable when moving. BRIEF DESCRIPTION OF THE DRAWINGS
