Abstract
A cutting instrument configured as scissors has a housing formed as a handle with a functional unit disposed therein; supported in the functional unit is a probe configured as a hollow needle which co-axially supports a rod projecting from the probe in axial direction and which comprises at its distal end a cutting device and wherein the cutting device has two cutting members provided with cutting blades that can be configured in an arc-shape or a straight shape, wherein from an open position the cutting blades correspond to each other at an acute angle, they are brought into engagement with each other to a closed position for a cutting action by means of a sliding movement of the probe relative to the scissors tip.
Claims22
A micro surgical cutting instrument configured as scissors comprising:
- a housing configured as a handle and a sliding device disposed therein;
- a probe configured as a hollow needle with a rod co-axially disposed therein;
- a cutting device disposed at a distal end of the rod and configured as scissors having two cutting members, each cutting member having one of an arcuate and straight configuration, each cutting member provided with a cutting blade and a cutting edge which, in an open position and extending from the distal end of the cutting blades towards the distal end of the probe, oppose each other at an acute angle such that when the probe is moved in the direction towards a tip of the cutting members the cutting edges engage each other to establish a cutting action.
