Technical Field

The invention belongs to the technical field of medical appliances, and particularly relates to an aspirator.

Background

In recent years, the incidence of thyroid surgery related diseases has been continuously rising, with most patients requiring surgical treatment. The thyroid surgery mainly comprises open surgery, endoscopic surgery and the like. Although the endoscopic surgery technique has the advantages of minimally invasive and the like, the operation is complex, the learning curve is short and the like, and the open surgery has the characteristics of full exposure, simple operation, short learning curve, high surgery efficiency, high safety and the like, and is still widely used by thyroid surgeons in hospitals of all levels, and is still the most main surgery mode of thyroid surgery at present. Especially complex and difficult operations that cannot be handled by the endoscope, open surgery is more irreplaceable. Open thyroid operation incision is most common with neck arc incision, because the special operation position and incision size are closely related with postoperative scar, great operation scar causes adverse effect to patient's neck aesthetic degree, patient's psychology etc..

With the increasing demands of surgical patients on trauma reduction and post-operation aesthetic appearance, open thyroid surgery is also continuously improved, wherein small incision minimally invasive surgery is accepted by most surgeons and patients, however, the small incision surgery has a narrower operation field, insufficient exposure and various auxiliary instruments are needed to realize field optimization. Wherein the aspirator is used for removing blood and effusion and other objects near the operation area so as to avoid burying and shielding the operation area. The retractor is adapted to pull surrounding tissue adjacent the procedure to expose a wider field of view.

In the prior art, on the one hand, the aspirator and the drag hook are separately and independently used, so when a small incision minimally invasive surgery is performed, the aspirator and the drag hook auxiliary instrument are required to be frequently replaced due to the influence of small factors of an incision area during the surgery, the risks of damage and major bleeding of related tissues and organs in the surgery are greatly increased, if related complications occur, great pain and potential safety hazard are brought to a patient, and meanwhile, extremely poor experience is brought to medical staff in the surgery operation. On the other hand, when the conventional aspirator is used in a minimally invasive operation with a small incision, the aspirator is pressed by tissues around an operation area, so that a suction port of the aspirator is extremely easy to be blocked.
