Multifunctional suction device for nasal endoscopic surgery

Abstract

The invention discloses a multifunctional aspirator for nasal endoscope surgeries. According to the structure of the multifunctional aspirator, a built-in suction tube is led out of the appropriate height position of a suction tube of an existing suction device in a branched mode, the branched position of the suction tube is provided with a three-way ball valve, the three-way ball valve is respectively connected with a total suction tube, a conventional suction tube and the built-in suction tube and controls a conventional suction tube and the built-in suction tube to be opened, closed and switched, and the front end of the built-in suction tube is expanded to be a spherical suction head. During the surgeries, the built-in suction tube remains in the nasal cavity, continuous suction is formed to a surgery cavity, and the problem that surgeons frequently alternately replace and use the aspirator and other devices is solved.

Description

technical field [0001] The invention relates to a medical device, in particular to an aspirator used in nasal endoscopic surgery. Background technique [0002] In contemporary otolaryngology medical practice, nasal endoscopy is widely used in nasal surgery. Aspirator is an essential instrument in nasal endoscopic surgery. In medical institutions with modern buildings, the suction device is centrally supplied and controlled, and only terminal equipment is installed in operating rooms and other application places. At present, the suction device for nasal endoscopic surgery routinely used clinically is to set the suction tube after passing through a suction bottle (equivalent to figure 1 4 in), the end is connected with a metal tip (equivalent to figure 1 In 5), the relevant surgical operation is completed by manipulating the metal suction head. The use of nasal endoscopic surgery aspirator is not only to suck blood and fluid in the nasal cavity, but also for dissection, se...

Another example is the U.S. Patent No. US6312441 "Powered handpiece for performing endoscopic surgical procedures" has been used clinically. It integrates the functions of attracting and cutting tissues, but it cannot be used for anatomical separation. In addition, it is equipped with a suction device, which also has the above-mentioned defects when it is used as a conventional suction device

In addition, the Chinese patent CN102125720 "built-in suction device for laparoscopic surgery" has similarities between "laparoscopic surgery" and "nasal endoscopic surgery", but its suction head has a complex structure and no anatomical separation function. Structurally and functionally, it cannot meet the requirements of nasal endoscopic surgery
