Endoscopic surgical trocar capable of maintaining the cleanliness of the endoscopic lens through the vortex supply of the cleaning agent

摘要

The present invention relates to an endoscopic surgical trocar, which comprises: a housing supplied with a cleaning agent from the outside; a bushing portion which extends to one side of the housing to a predetermined length, and in which the endoscope is slidably inserted therein, and which has a moving path through which the cleaning agent flowing from the housing flows; and a vortex generating portion having one end connected to a front end of the bushing portion and having an inclined path formed in an obliquely inclined shape on the inner side to form a vortex in the cleaning agent introduced from the moving path and to discharge the same to the other end. The cleaning agent flowing along the moving path is discharged in a vortex form inward through the inclined path.
