SURGICAL INSTRUMENT FOR DISPENSING A FLUID

摘要

A surgical instrument (10) for dispensing a fluid (12). The instrument includes a housing (20). The instrument also includes a dispensing shaft (30) which is elongate and which has a proximal end (31) and a distal end (32). The proximal end of the dispensing shaft is received in the housing and the distal end defines a dispensing opening for dispensing the fluid. The dispensing shaft includes a through bore (37) which extends along the dispensing shaft from the proximal end to the dispensing opening at the distal end. The instrument further includes a dispensing assembly (80). The instrument also includes a priming assembly (60) connected to the housing which is operable to move an amount of the fluid into the through bore of the dispensing shaft to prime the through bore with the fluid before the dispensing assembly is operated.
