Abstract
Abstract This invention provides an improved endoscope having control wires for articulating a set of rings and directing a probe which further provides an overload protection device interconnecting the control wires to an operating member. The overload protection device provides a controlled resiliency to inhibit the application of excess tension to the control wires but provides sufficient force to manipulate the probe.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
An endoscope comprising a set of articulated rings, a probe mounted to one end of said rings, means for articulating said rings to direct or redirect said probe including a rotatable operating member and a wire connected to said articulated rings; wherein an overload protection means interconnects said wire to said operating member, said overload protection means providing controlled resiliency to inhibit the application of excess tension to said wire and comprising a cylinder connected to said operating member, a piston connected to said wire and slidably received within said cylinder, a spring engaged with said piston and resiliently biasing said piston into said cylinder, and a spring retainer for capturing said spring within said cylinder and applying a preset biasing force upon said piston.
Claim 2
Dependent Claim
125 words
An endoscope comprising a set of articulated rings, a probe mounted to one end of said rings, means for articulating said rings to direct or redirect said probe including a rotatable operating member and a wire connected to said articulated rings; wherein an overload protection means interconnects said wire to said operating member, said overload protection means providing controlled resiliency to inhibit the application of excess tension to said wire and comprising a cylinder connected to said operating member, a piston connected to said wire and slidably received within said cylinder, a spring engaged with said piston and resiliently biasing said piston into said cylinder, and a spring retainer for capturing said spring within said cylinder and applying a preset biasing force upon said piston.
Claim 3
Dependent Claim
29 words
The endoscope of claim 1, said overload protection means further including an adjustable means intermediate said piston and wire for setting the slack or operating tension in said wire.
Claim 4
Dependent Claim
53 words
The endoscope of claim 2, said piston being internally threaded, said adjustable means intermediate said piston and wire comprising an externally threaded sleeve threadably engaged with said piston, and means connecting said wire to said sleeve for setting the slack or tension in said wire upon threaded adjustments between said piston and sleeve.
Claim 5
Dependent Claim
114 words
An overload protection device for use in an endoscope having a probe and means for articulating the probe, including a pair of wires connected to a rotatable operating member, and means for interconnecting a wire to the operating member to provide controlled resiliency that inhibits the application of excess tension in said wire, said overload protection device comprising: a cylinder adapted for connection to the operating member, a piston adapted for connection to the wire and slidably received within said cylinder, a spring engaged with said piston and resiliently biasing said piston into said cylinder, and a spring retainer capturing said spring within said cylinder and applying a preset biasing force to said piston.
Claim 6
Dependent Claim
114 words
An overload protection device for use in an endoscope having a probe and means for articulating the probe, including a pair of wires connected to a rotatable operating member, and means for interconnecting a wire to the operating member to provide controlled resiliency that inhibits the application of excess tension in said wire, said overload protection device comprising: a cylinder adapted for connection to the operating member, a piston adapted for connection to the wire and slidably received within said cylinder, a spring engaged with said piston and resiliently biasing said piston into said cylinder, and a spring retainer capturing said spring within said cylinder and applying a preset biasing force to said piston.
Claim 7
Dependent Claim
29 words
The overload protection device of claim 4, and further including an adjustable means intermediate said piston and wire for setting the slack or operating tension applied to the wire.
Claim 8
Dependent Claim
56 words
The overload protection device of claim 5, said piston being internally threaded, said adjustable means intermediate said piston and wire comprising an externally threaded sleeve threadably engaged with said piston, and means for connecting the wire to said sleeve to set the slack or tension in the wire upon threaded adjustments between said piston and sleeve.
