Abstract

Abstract A device for the remote control of motions and operations, especially on microsurgical equipment, comprises a multiple switch assembly in which the operation of the selected switches is controlled by movement of a control member. Operation of the switches closes or opens electrical circuits which include servo-mechanisms for moving the equipment. The switches are mounted in a housing and the control member comprises a plate having a stud extending through an aperture in the cover of the housing. Selective operation of the switches is brought about by transverse movement of the plate and stud in various directions.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 167 words
In an operating chair for surgical operations under a microscope, having a control panel on which the chair is mounted, a plurality of switch assemblies mounted in the upper surface of said panel and arranged for operation by a surgeon's foot for the remote control of motions and operations of surgical and microscopical equipment, each of said switch assemblies comprising a housing, a cover plate for said housing, said cover plate having an aperture extending therethrough, a control member mounted above said cover plate and being laterally slidable thereon, said control member having a stud secured thereto which extends downwardly through said aperture, the diameter of said stud being less than the diameter of said aperture, a plurality of switches mounted within said housing and arranged around said stud, and means carried by said stud for actuating any selected one of said switches on lateral movement of said control member and stud in a direction transverse to the axis of said stud and toward said selected switch.
Claim 2
Dependent Claim 167 words
In an operating chair for surgical operations under a microscope, having a control panel on which the chair is mounted, a plurality of switch assemblies mounted in the upper surface of said panel and arranged for operation by a surgeon's foot for the remote control of motions and operations of surgical and microscopical equipment, each of said switch assemblies comprising a housing, a cover plate for said housing, said cover plate having an aperture extending therethrough, a control member mounted above said cover plate and being laterally slidable thereon, said control member having a stud secured thereto which extends downwardly through said aperture, the diameter of said stud being less than the diameter of said aperture, a plurality of switches mounted within said housing and arranged around said stud, and means carried by said stud for actuating any selected one of said switches on lateral movement of said control member and stud in a direction transverse to the axis of said stud and toward said selected switch.
Claim 3
Dependent Claim 31 words
Apparatus as claimed in claim 1 in which said aperture is provided with a plurality of symmetrically arranged radial flutes, and in which said stud is dimensioned to enter said flutes.
Claim 4
Dependent Claim 32 words
Apparatus as claimed in claim 2 in which the number of switches in said housing corresponds to the number of said flutes, and in which said switches are aligned with said flutes.
