Abstract

The invention discloses a pair of dacryocyst and nasal cavity anastomosis scissors comprising a first scissor body and a second scissor body which are crossly hinged together, wherein a handle part of the first scissor body is provided with a first finger ring; a handle part of the second scissor body is provided with a second finger ring; a head part of the first scissor body is provided with a first knifepoint bending towards a direction close to a head part of the second scissor body; the head part of the second scissor body is provided with a second knifepoint; and the bending direction of the second knifepoint is the same as that of the first knifepoint. The pair of dacryocyst and nasal cavity anastomosis scissors disclosed by the invention has the advantages of being simple in structure, convenient in use, capable of smoothly entering an operation position to accurately perform shearing, and the like.

Description

technical field [0001] The invention relates to medical auxiliary equipment, in particular to a dacryocystorhinostomy scissors, which are mainly used for making regular lacrimal sac flaps and nasal mucosa flaps during the dacryocystorhinostomy operation for easy anastomosis. Background technique [0002] In the dacryocystorhinostomy for chronic dacryocystitis, the lacrimal fossa is separated to expose the lacrimal sac, and a bone window is opened at the lacrimal fossa to expose the nasal mucosa. The operator needs to cut the side wall of the lacrimal sac and the nasal mucosa. Connect the lacrimal sac cavity with the nasal cavity, thereby opening up a new lacrimal drainage channel. Due to the very narrow space of the surgical site, resulting in a small visual range and a small range of movement of the scissors, it is very difficult for conventional surgical scissors to enter the surgical site and perform cutting at the surgical site. Contents of the invention [0003] The ...
