Abstract
Abstract A clamp for clamping instrumentation uses a resilient tube (507) and a compression housing (600) operatively associated with the tube for providing a compressive force on the tube. The compressive force is distributed generally equally over the length of the tube so that instrumentation disposed through the tube is substantially secured within the housing with minimal deformation. The clamp is especially adaptable to fragile instrumentation, such as optical fibers, which typically are clamped for manipulation. In one embodiment, the clamp is permanently attached to one instrument, while clamping another instrument for simultaneous manipulation. In another embodiment, the instrumentation clamp can couple to one instrument temporarily, while clamping another instrument. This embodiment is designed to be self contained and readily adaptable for multiple uses.

Claim 5
Dependent Claim
38 words
A device as claimed in claim 4 wherein the housing has receiving means for receiving the protrusion means when the clamp is inserted, the receiving means and the protrusion means cooperating to apply force to the resilient tube.
Claim 6
Dependent Claim
37 words
A device as claimed in claim 5 wherein rotation of the housing with respect to the clamp in a first direction causes the cooperation between the receiving means and the protrusion means to secure such an instrument.
Claim 7
Dependent Claim
39 words
A device as claimed in claim 5 wherein the rotation of the housing in a first direction causes the plurality of compression legs to move toward the resilient tube to compress the resilient tube to secure such an instrument.
Claim 8
Dependent Claim
31 words
A device as claimed in claim 8 wherein receiving means comprises a retention slot and a curved recess on an inside radius of the housing for each of the compression legs.
Claim 9
Dependent Claim
55 words
A device as claimed in claim 8 wherein the protrusion means comprises a substantially cylindrical boss and an engagement projection near the movable end of each of the compression legs, wherein the engagement projection and the cylindrical boss extend radially toward the housing, and wherein the engagement projection extends further than the cylindrical boss extends.
Claim 10
Dependent Claim
44 words
A device as claimed in claim 9 wherein the curved recess receives both the cylindrical boss and the engagement projection while the clamp is being inserted into the housing, and the retention slot receives the engagement projection to retain the clamp in the housing.
Claim 11
Independent Claim
40 words
A device as claimed in any one of claims 6-10 wherein rotation of the housing with respect to the clamp in a second direction causes the cooperation between the receiving means and the protrusion means to release such an instrument.
Claim 12
Dependent Claim
72 words
A clamping device for clamping an instrument comprising a first part permanently associated with an elongate tube for inserting such an instrument percutaneously, the first part having a first bore therethrough, and a second part for receiving such an instrument, the second part having a second bore therethrough, the second part being permanently affixed and adjacent to the first part, so that the first bore is generally aligned with the second bore.
Claim 13
Dependent Claim
24 words
A device as claimed in claim 12 wherein the first part is made from a material which can be readily sterilized with minimal distortion.
Claim 14
Dependent Claim
58 words
A clamping device as claimed in claim 12 wherein the second part comprises: a resilient tube for grasping such an instrument; a clamp surrounding the resilient tube for compressing the resilient tube; and a housing operatively associated with the clamp, the housing being rotatable with respect to the clamp to force the clamp to compress the resilient tube.
