Description

[0002] In actual neurosurgical clinical diagnosis and treatment work, in order to ensure accurate judgment of tumor nature, specimen sampling and detection work need to be carried out. When sampling deep tumors, endoscopic assisted sampling is a common sampling method. For tumors in the ventricular system or adjacent to the ventricle, doctors usually use endoscopic biopsy to accurately sample under the assistance of a visual probe, reducing damage to surrounding brain tissue. Neurosurgery involves the diagnosis and treatment of the nervous system of the brain, and the safety of sampling needs to be ensured. The current neurosurgical clinical tumor specimen taking device is mainly operated by the doctor holding the endoscope.

[0038] The working principle of the embodiment is as follows: first, the positioning inflatable tube 303 is placed between the left and right brain sutures, a small amount of air is filled through the external air pump, and the stability of the positioning film sleeve 302 is maintained. The positioning inflatable tube 303 can also be sleeved on the skull opening of the patient for positioning. The actual sampling depth and tumor position can be adjusted. When the working inflatable ball 4011 approaches sensitive positions such as the brain stem, fine adjustment work is performed. The air pump connected to the air duct 204 is started, and the telescopic bellows 202 is inflated.

Subsequently, the probe of the endoscope main body 101 itself can be used to observe the tumor position, and the sampling forceps in the working channel 1012 can be used to perform sampling work by using the existing mature endoscopic technology.

[0039] The supporting air connection pipe 604 is opened, and the air pump connected to the supporting air connection pipe 604 is started.

At this time, the three-way valve 602 is rotated to connect the detection pipe 603. The air pressure in the working inflatable ball 4011 is connected to the air pressure pipe 605. Once the working inflatable ball 4011 is excessively squeezed by the brain stem or the working inflatable ball 4011 is excessively inflated and squeezed by the left and right brain, the air pressure will push the air pressure piston 606 to compress the anti-misoperation spring 6061, and then press the alarm switch 607, control the warning light 608 to light, and realize detection.
