INSTRUMENT HANDLE AND REPLACEABLE TIP

摘要

An instrument handle and replaceable tip may include a reusable instrument handle and a single-use instrument tip. The instrument tip may include an outer base, a nosecone, a pressure mechanism, a hypodermic tube, a blank, and a fixation mechanism. The instrument handle may include an actuation structure, a fixation mechanism receptacle, and an instrument tip housing. The fixation mechanism and the fixation mechanism receptacle may be configured to temporarily fix the instrument tip in the instrument tip housing. A compression of the actuation structure may be configured to actuate the hypodermic tube relative to the blank. The instrument tip may be removed from the instrument tip housing after use by removing the fixation mechanism from the fixation mechanism receptacle.

1. An instrument comprising:
a handle having a handle distal end and a handle proximal end; an actuation structure of the handle having an actuation structure distal end and an actuation structure proximal end; a plurality of actuation arms of the actuation structure; a fixation mechanism proximal receptacle having a fixation mechanism proximal receptacle distal end, a fixation mechanism proximal receptacle proximal end, and a fixation mechanism proximal housing, the fixation mechanism proximal receptacle disposed in the actuation structure; an instrument tip housing of the actuation structure; an instrument tip having an instrument tip distal end and an instrument tip proximal end; a transitory element of the instrument tip having a transitory element distal end and a transitory element proximal end; is a hypodermic tube of the instrument tip having a hypodermic tube distal end and a hypodermic tube proximal end wherein the hypodermic tube proximal end is disposed in the transitory element; a blank of the instrument tip having a blank distal end and a blank proximal end wherein the blank is disposed in the hypodermic tube and the transitory element; and a fixation mechanism disposed in the transitory element and the fixation mechanism proximal housing wherein the fixation mechanism and the fixation mechanism proximal receptacle are configured to temporarily fix the instrument tip in the instrument tip housing.
