Abstract

The invention provides a nasal cavity-lacrimal sac fistulation instrument with easy surgical operation and convenient use, and belongs to medical appliances. The nasal cavity-lacrimal sac fistulation instrument comprises a puncturing lever; the rear end of the puncturing lever is connected with a hand-held machine, while the front end is connected with a security ring; and the security ring is connected with a triangular puncture outfit which has a taper structure. The nasal cavity-lacrimal sac fistulation instrument is used for chronic dacryocystitis intranasal endoscopic nasal cavity-lacrimal sac re-dredging operations, can be operated in small nasal cavities and does not influence the use of a nasal endoscope so as to have clear visual field and ensure the smooth completion of the operations.

Description

technical field [0001] The invention relates to a medical device, in particular to a nasal cavity dacryocystostomy device. Background technique [0002] At present, during the recanalization of the nasal cavity and lacrimal duct in chronic dacryocystitis, the lacrimal bone window is generally opened with a chisel, and the expansion of the bone window through the chisel is a key part of the operation. During transnasal endoscopic surgery, because the nostrils are too small, the field of view cannot be guaranteed when performing lacrimal fenestration with an osteotome, and the operation is difficult to perform, making it very difficult to complete the operation. Contents of the invention [0003] The object of the present invention is to provide a nasal cavity dacryocystostomy device which can make operation operation easy and convenient to use. [0004] To achieve the above object, the technical solution adopted in the present invention is: [0005] A nasal dacryocystosto...
