Abstract
Abstract An improved surgical microscope particularly useful in ophthalmic surgery of the type comprising a base member, an adjustable support column extending upwardly therefrom and means projecting from the support column to suspend the optical components of a microscope and related auxiliary equipment above the operating area. The improvement resides in a novel arrangement of structural elements providing an adjustable support column which is advantageously integrated with other structural components of the microscope.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
286 words
A microscope for surgical use having optical components adjustably mounted above the operating area, said microscope comprising: a base member; means remote from said base member for suspending the optical components of said microscope above the operating area; and support means connecting said suspending means to said base member, said support means being capable of adjusting the distance between said base member and said suspending means between predetermined limits, said support means comprising: a first column member secured to said base member; a second column member secured to said suspending means, said second column member being arranged in telescopic coaxial relationship with said first column member; motive means secured to said first column member; and means coupled at one end to said motive means and secured at the other end to said second column member for extending and retracting said second column member with respect to said first column member; wherein said motive means comprises: a motor secured to said first column member; a threaded spindle coupled to said motor for rotation therewith, said spindle extending into said first column member; an end plate mounted in said second column member; a plurality of parallel elongated rods, each secured at one end to said end plate and extending into said first column member; an actuator plate secured to the other end of each of said elongated rods, said actuator plate being provided with internal threads for engaging said spindle in threaded relationship; whereby upon rotation of said motor in one direction said second column member is extended with respect to said first column member and whereby upon rotation of said motor in the opposite direction said second column member is retracted with respect to said first member.
Claim 2
Dependent Claim
286 words
A microscope for surgical use having optical components adjustably mounted above the operating area, said microscope comprising: a base member; means remote from said base member for suspending the optical components of said microscope above the operating area; and support means connecting said suspending means to said base member, said support means being capable of adjusting the distance between said base member and said suspending means between predetermined limits, said support means comprising: a first column member secured to said base member; a second column member secured to said suspending means, said second column member being arranged in telescopic coaxial relationship with said first column member; motive means secured to said first column member; and means coupled at one end to said motive means and secured at the other end to said second column member for extending and retracting said second column member with respect to said first column member; wherein said motive means comprises: a motor secured to said first column member; a threaded spindle coupled to said motor for rotation therewith, said spindle extending into said first column member; an end plate mounted in said second column member; a plurality of parallel elongated rods, each secured at one end to said end plate and extending into said first column member; an actuator plate secured to the other end of each of said elongated rods, said actuator plate being provided with internal threads for engaging said spindle in threaded relationship; whereby upon rotation of said motor in one direction said second column member is extended with respect to said first column member and whereby upon rotation of said motor in the opposite direction said second column member is retracted with respect to said first member.
Claim 3
Dependent Claim
84 words
The microscope recited in claim 1, wherein: said support means further comprises: a stabilization member secured to said elongated rods intermediate their ends; and a plurality of bearing members secured to said first column member intermediate the ends of said elongated rods, said bearing members being provided with a plurality of openings through which said elongated rods slide, a first bearing member residing on one side of said stabilization member and a second bearing member residing on the other side of said stabilization member.
Claim 4
Dependent Claim
57 words
The microscope recited in claim 2, and further comprising: a mounting plate secured within said first column member, said motor being secured to said mounting plate; a spindle bearing mounted in said mounting plate; and a guide bushing mounted in said first bearing member; said spindle being rotatably mounted between said spindle bearing and said guide bushing.
Claim 5
Dependent Claim
70 words
The microscope recited in claim 3, wherein: said first bearing member is located between and spaced a predetermined distance from said mounting plate and said second bearing member; said stabilization member is located between and spaced said predetermined distance from said actuator plate and said end plate; the distance between said base member and said suspending means being adjustable through a range which is substantially equal to said predetermined distance.
Claim 6
Dependent Claim
58 words
The microscope recited in claim 3, wherein: said end plate, second bearing member and stabilization member are each provided with an axial opening; and said first bearing member, actuator plate and mounting plate are each provided with an off-axis opening; said openings being adapted for guidance of electrical cables extending between said base member and said optical components.
Claim 7
Dependent Claim
256 words
For use in a surgical microscope having optical components, a base member and means remote from said base member for suspending said optical components above the operating area, an adjustable support column comprising: a first column member secured to said base member; a second column member secured to said suspending means and arranged in adjustable telescopic coaxial relationship with said first column member; a mounting plate secured within said first column member; a reversible motor secured to said mounting plate; a threaded spindle axially located within said first column member and coupled to said motor for rotation therewith; an end plate secured to said second column member; three parallel elongated rods, each secured at one end to said end plate, said elongated rods being equiangularly arranged about the axis of said support column; an actuator plate secured to the other end of each of said elongated rods; an actuator nut mounted in said actuator plate and engaging said spindle in threaded relationship; a first bearing member secured within said first column member at a predetermined distance from said mounting plate; a second bearing member secured within said first column member at said predetermined distance from said first bearing member; a stabilization member secured to said elongated rods intermediate their ends and spaced at said predetermined distance from said actuator plate and from said end plate; a spindle bearing mounted in said mounting plate; and a guide bushing mounted in said first bearing member; said spindle being rotatably mounted between said spindle bearing and said guide bushing.
