Embodiment Construction

[0021] Such as Figure 1-3 As shown, a composite suction and irrigation device for sinus endoscopic surgery in this embodiment includes a flat tube 4 and a flushing mechanism and a suction mechanism arranged on the flat tube 4 .

[0022] The flat tube 4 is made of hard hollow plastic material, and its cross section is roughly oval. The outer periphery of the flat tube 4 is provided with inflatable bags 8 distributed along its circumferential direction, and the number of the inflatable bags 8 is two, which are respectively sleeved and fixed on both ends of the flat tube 4 in the longitudinal direction. Two inflatable bags 8 are respectively connected to inflatable equipment (conventional technical means in the art, not shown in the figure) through flexible inflatable tubes. 8 Position the flat tube 4 on the nasopharynx 15 of the patient, so that the sinus endoscope and the operation cavity can be flushed and sucked through the flushing mechanism and suction mechanism arranged ...

Abstract

A suction and flushing combined device for paranasal sinus endoscopic surgery comprises a flat tube, a flushing mechanism and a suction mechanism, the flushing mechanism and the suction mechanism are arranged on the flat tube, an inflation bag distributed in the circumferential direction of the flat tube is arranged on the periphery of the flat tube, and a partition plate dividing an inner cavity of the flat tube into two longitudinal cavities is arranged in the flat tube; the suction mechanism comprises a hole cover which is arranged at the front end of the longitudinal cavity and is provided with a suction hole and a suction pipe which is arranged at the rear end of the longitudinal cavity, and the suction pipe is connected with negative pressure suction equipment; the flushing mechanism comprises a liquid spraying nozzle arranged on the hole cover and a flushing pipe connected to the liquid spraying nozzle, and the flushing pipes in the two longitudinal cavities extend out of the flat pipe and then are connected to flushing liquid positive pressure supply equipment through a three-way valve. The nasal cavity and paranasal sinus endoscope flushing device facilitates flushing of nasal cavity and paranasal sinus endoscopes in an operation, shortens operation time, improves operation safety and avoids discomfort caused by the fact that flushing fluid flows into intestines and stomach.

Description

technical field [0001] The invention relates to the field of medical equipment for nasal surgery, in particular to a composite suction and flushing device for sinus endoscopic surgery. Background technique [0002] The current nasal cavity surgery mostly uses a sinus endoscope to operate in the nasal cavity, which has the characteristics of small and deep holes. In nasal cavity surgery, the requirements for vision are very high, and only in a clear vision can efficient and safe operations be performed. The main factors affecting the progress of the operation are the accumulation of blood and fluid in the operation cavity and the degree of cooperation of the assistant or / patient. The clarity of the lens and the cleanliness of the surgical cavity are the key factors for whether local anesthesia can be tolerated, shorten the operation time, improve the safety of the operation and improve the quality of the operation. It is an urgent problem to be solved in sinus endoscopic su...
