Abstract

A system for controlling a plurality of ophthalmic microsurgical instruments is disclosed. Particularly, the present invention includes a handpiece for activating a surgical instrument (i.e., such as scissors) connected to the handpiece. The handpiece includes a housing and a linear activator operatively retained within the housing. A nosepiece is mounted to one end of the housing and is adapted for correction of a linearly actuated surgical instrument. The nosepiece is fixed to the linear activator in a preselected calibrated position relative to the longitudinal axis of the linear actuator.

Claims

1. A handpiece for actuating a linearly actuated surgical instrument connected to the handpiece comprising:

a linear actuator operatively retained within the housing having a longitudinal, distal tip;

a nosepiece mounted to the first end of the housing and adapted for connection of a surgical instrument, the nosepiece being fixed to the linear actuator in a preselected calibrated position relative to the longitudinal tip of the linear actuator; and

the second end of the housing being enclosed and liquid-tight, wherein the nosepiece is provided at least in part with a slick coating.

2. A handpiece for actuating a linearly actuated surgical instrument connected to the handpiece comprising:

a linear actuator operatively retained within the housing having a longitudinal, distal tip;

a nosepiece mounted to the first end of the housing and adapted for connection of a surgical instrument, the nosepiece being fixed to the linear actuator in a preselected calibrated position relative to the longitudinal tip of the linear actuator; and

the second end of the housing being enclosed and liquid-tight, wherein the nosepiece has an elastomeric soft-grip coating.
