Abstract

Abstract An adjustable position fixing apparatus for fixing instruments such as an endoscope and an illuminator in a desired spatial position is provided. The adjustable position fixing apparatus for an instrument and the like comprises a cylinder communicating with a pressure fluid supplying machine, such as a compressor, through a switching device, a mount member for mounting an instrument and the like thereon, and an adjustable bending arm portion through which a linear element such as a wire extends. The arm portion is disposed between the cylinder and the mount member over an entire area or a part thereof. One end of the linear element is attached to a reciprocating rod of the cylinder and the other end is attached to the mount member.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 159 words
An adjustable position fixing apparatus for an instrument, comprising: a housing defining a volume: a bendable arm extending from said housing; means for mounting an instrument on said bendable arm; a rod reciprocally movable within said housing; a tensionable element extending through said rod and through said bendable arm to said mounting means; means for reciprocating said rod within said housing, said reciprocating means including at least one chamber within said housing, at least one piston displaceable within said at least one chamber, and pressure means for supplying a fluid under pressure to said at least one chamber via a flow channel that extends through said rod, said rod being connected to said at least one piston for joint reciprocal movement in response to pressure changes in said at least one chamber; and means responsive to said reciprocal movement of said rod in one direction for tensioning said tensionable element and in the other direction for loosening the tension.
Claim 2
Dependent Claim 159 words
An adjustable position fixing apparatus for an instrument, comprising: a housing defining a volume: a bendable arm extending from said housing; means for mounting an instrument on said bendable arm; a rod reciprocally movable within said housing; a tensionable element extending through said rod and through said bendable arm to said mounting means; means for reciprocating said rod within said housing, said reciprocating means including at least one chamber within said housing, at least one piston displaceable within said at least one chamber, and pressure means for supplying a fluid under pressure to said at least one chamber via a flow channel that extends through said rod, said rod being connected to said at least one piston for joint reciprocal movement in response to pressure changes in said at least one chamber; and means responsive to said reciprocal movement of said rod in one direction for tensioning said tensionable element and in the other direction for loosening the tension.
Claim 3
Dependent Claim 41 words
An apparatus as in claim 1, wherein said bendable arm is comprised of a plurality of arm components connected together in succession in a ball and socket manner, said arm components each having through-going holes through which extends said tensionable element.
Claim 4
Dependent Claim 34 words
An apparatus as in claim 1, further comprising a tubular member extending from said housing to said bendable arm, said tensionable element extending through said tubular element as well as through said bendable arm.
Claim 5
Dependent Claim 38 words
An apparatus as in claim 1, further comprising an adjustment handle adjustably secured to said rod for displacement relative thereto, said tensionable element having an end secured to said adjustment handle and movable together with said adjustment handle.
Claim 6
Dependent Claim 45 words
An apparatus as in claim 1, wherein said bendable arm includes a plurality of elements that come into pressure contact with each other in response to said tensionable element being tensioned for fixing an instrument mounted by said mounting means into a desired spatial position.
Claim 7
Dependent Claim 148 words
An adjustable position fixing apparatus for an instrument, comprising: a housing defining a volume: a bendable arm extending from said housing; means for mounting an instrument on said bendable arm; a rod reciprocally movable within said housing; a tensionable element extending through said rod and through said bendable arm to said mounting means; and means for reciprocating said rod within said housing, said reciprocating means including a plurality of axially spaced chambers within said housing, a plurality of axially spaced pistons displaceable within respective ones of said chambers, and pressure means for supplying a fluid under pressure to each of said chambers, said rod being connected to said pistons for joint reciprocal movement in response to presssure changes in said chambers; and means responsive to said reciprocal movement of said rod in one direction for tensioning said tensionable element and in the other direction for loosening the tension.
Claim 8
Dependent Claim 148 words
An adjustable position fixing apparatus for an instrument, comprising: a housing defining a volume: a bendable arm extending from said housing; means for mounting an instrument on said bendable arm; a rod reciprocally movable within said housing; a tensionable element extending through said rod and through said bendable arm to said mounting means; and means for reciprocating said rod within said housing, said reciprocating means including a plurality of axially spaced chambers within said housing, a plurality of axially spaced pistons displaceable within respective ones of said chambers, and pressure means for supplying a fluid under pressure to each of said chambers, said rod being connected to said pistons for joint reciprocal movement in response to presssure changes in said chambers; and means responsive to said reciprocal movement of said rod in one direction for tensioning said tensionable element and in the other direction for loosening the tension.
Claim 9
Dependent Claim 61 words
An apparatus as in claim 6, wherein said channels are spaced axially from each other in succession by respective partitions, neighboring ones of said partitions and said pistons being separated from each other in succession by spaces in said channels, said supplying pressure means including a flow channel extending through said rod and being in communication with each of said spaces.
Claim 10
Dependent Claim 45 words
An apparatus as in claim 5, wherein said bendable arm includes a plurality of elements that come into pressure contact with each other in response to said tensionable element being tensioned for fixing an instrument mounted by said mounting means into a desired spatial position.
