Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a transnasal skull base endoscope aspirator. Background Art
[0002] Due to the complexity and diversity of the brain's nervous system, cranial surgery has always been a high-risk area of surgical surgery. With the continuous advancement of medical technology, from the initial craniotomy to now, it has developed to various skull base surgeries performed through endoscopic observation via the nasal cavity. Compared with traditional craniotomy, transnasal skull base surgery can minimize the harm to patients. At the same time, since the entire operation is performed under endoscopic monitoring, the lesions are clearer than when the doctor sees directly, so transnasal skull base surgery is becoming more and more popular among doctors and patients.
[0003] With the gradual promotion of neuroendoscopic technology, thanks to its advantages of small surgical trauma, clear surgical field of view, and fast postoperative recovery, transnasal endoscopic skull base surgery represented by neuroendoscopic transsphenoidal pituitary tumor resection has developed rapidly, and its indications have gradually expanded. The technical requirements for the surgeon and assistants are getting higher and higher. Keeping the surgical field and lens clear is the basic requirement of transnasal endoscopic surgery and one of the main tasks of assistants. At present, during the operation, the assistant mainly injects saline from the nasal cavity on the same side of the surgery with a flushing ball to keep the lens clear, and inserts a metal suction tube from the nasal cavity on the same side or the opposite side of the surgery to keep the surgical field clear. However, due to the small space of the nasal cavity, mutual interference between instruments will affect the efficiency of the operation. In addition, repeated flushing from the outside of the nose to the inside of the nasal cavity has the risk of bringing bacteria into the nasal cavity. Another suction scheme is to use a suction tube placed at a low position in the surgical field, which can keep the surgical field clear at all times. The disadvantage is that it is easy to block the tube and needs to be repeatedly in and out of the nasal cavity, affecting the operation process.
[0004] Therefore, there is a need for a transnasal skull base endoscopic aspirator that can avoid frequent flushing or suction of the patient's nasal cavity, avoid introducing bacteria into the patient's nasal cavity, or excessive flushing and suction that may damage the patient's nasal tissue.

[0011] As a preferred technical solution of a transnasal skull base endoscopic aspirator of the utility model, a row of teeth is fixedly provided on the upper side wall of the traction plate, and one end of the limit plate is engaged with the row of teeth.
[0012] As a preferred technical solution of a transnasal skull base endoscopic aspirator of the utility model, a connecting hole is provided in the middle of the top surface of the threaded cover, and the suction tube passes through the connecting hole.
[0013] As a preferred technical solution of the transnasal skull base endoscope aspirator of the utility model, a cotton brush head is provided on the bottom surface of the moisture-absorbing cotton ring, and a plurality of the cotton brush heads are provided.
[0014] As a preferred technical solution of a transnasal skull base endoscopic aspirator of the utility model, there are multiple liquid guide grooves, multiple liquid guide holes, and multiple filter holes.
[0015] Compared with the existing technology, the utility model has the following beneficial effects:
[0016] The utility model uses the provided moisture absorption component to absorb and process foreign matter such as mucus in the patient's nasal cavity, ensuring the smooth progress of the operation. The bottom surface of the nasal tube is provided with a liquid guide hole, the lower end of the outer wall of the nasal tube is provided with a liquid guide groove, and the bottom of the moisture absorption cotton ring is provided with a cotton brush head. The mucus in the patient's nasal cavity can be conveniently absorbed by the moisture absorption cotton ring through the liquid guide groove and the liquid guide hole, and the cotton brush head can absorb other foreign matter in the patient's nasal cavity, ensuring the smooth progress of the operation. When the moisture absorption cotton ring needs to be replaced, the medical staff holds the holding plate with one hand and pinches the fixing ring with the other hand, and pulls it to one side to drive the traction plate to move. The hygroscopic cotton ring can be pulled out of the nasal tube and separated from the threaded cover by twisting the hygroscopic cotton ring, so that the hygroscopic cotton ring can be quickly replaced. When the traction plate is pulled out of the nasal tube, the row of teeth at one end of the traction plate collides with the two inclined surfaces at one end of the limiting plate. The collision of the inclined surface at one end of the limiting plate will drive the limiting plate to move into the plug-in slot, which will not affect the pulling out of the hygroscopic cotton ring from the nasal tube. The scheme can avoid frequent flushing or suction of the patient's nasal cavity and avoid bringing bacteria into the patient's nasal cavity, or excessive flushing and suction causing damage to the patient's nasal tissue through the effect of the hygroscopic component.
[0017] The utility model is connected with an external suction pump body or flushing pipeline through the suction tube provided. When there are too many foreign bodies in the patient's nasal cavity and it is impossible to deal with them only through the moisture absorption component, the patient's nasal cavity can be suctioned or flushed through the suction tube. The filter hole provided at one end of the suction tube can filter the foreign bodies and prevent the foreign bodies from entering the patient's nasal cavity. Before suction or flushing, the medical staff can hold the holding plate with one hand and pinch the fixing ring with the other hand, and drive the moisture absorption cotton ring to move to the side of the liquid guide groove and the filter hole by pulling the traction plate to ensure that the moisture absorption cotton ring does not affect suction or flushing. When the traction plate slides into the nasal tube, the limit plate The row of teeth at one end and the traction plate at one end are two planes colliding with each other, and the limit plate can play a limiting role to ensure that the moisture-absorbing cotton ring will not slide into the nasal tube. When the suction or flushing is completed, you can press the adjustment arc plate with your fingers, and then slide the adjustment arc plate to the side away from the nasal tube, driving one end of the limit plate to separate from the row of teeth, and then the moisture-absorbing cotton ring can be replaced at the bottom of the nasal tube to absorb foreign matter. This solution can take into account both nasal suction or flushing operations and the moisture-absorbing cotton ring's adsorption of foreign matter, which is sufficient to meet the needs of most transnasal skull base surgeries, and the operation is simple and convenient, which helps to improve efficiency.
