Abstract
Abstract A seal for use in a surgical instrument to provide a gas-tight seal with an instrument passed through the seal. The seal can form a gas-tight seal with an instrument having a diameter within a wide range of diameters. The seal comprises a seal body, an instrument seal, and a laterally-compliant seal mounting device. The seal body includes a bore through which the instrument is passed. The instrument seal is made of an elastic material and is disposed substantially perpendicular to the axis defined by the bore in the seal body. The instrument seal includes an instrument port through which the instrument is passed. The laterally-compliant seal mounting device mounts the instrument seal to the seal body, forms a gas-tight seal between the instrument seal and the seal body, and allows the instrument seal to move freely laterally in response to lateral movement of the instrument.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
201 words
A seal for use in a surgical instrument to provide a gas-tight seal with an instrument passed through the seal, the instrument having a diameter in a wide range of diameters, the seal comprising: a seal body including a bore wherethrough the instrument is passed, the bore defining an axis; an instrument seal of an elastic material, the instrument seal being substantially perpendicular to the axis and including an instrument port wherethrough the instrument is passed; a laterally-compliant seal mounting means for mounting the instrument seal to the seal body, for forming a gas-tight seal between the instrument seal and the seal body, and for allowing the instrument seal to move freely laterally in response to lateral movement of the instrument, wherein the laterally-compliant seal mounting means includes a rigid annulus and a laterally-compliant annulus disposed between the rigid annulus and the seal body, and wherein the instrument seal is attached to the rigid annulus with the instrument port inside the annulus; and a lateral force transmitting means for transmitting a lateral force from the instrument directly to the laterally-compliant seal mounting means to move the instrument seal laterally with a reduced lateral force between the instrument and the instrument port.
Claim 2
Dependent Claim
201 words
A seal for use in a surgical instrument to provide a gas-tight seal with an instrument passed through the seal, the instrument having a diameter in a wide range of diameters, the seal comprising: a seal body including a bore wherethrough the instrument is passed, the bore defining an axis; an instrument seal of an elastic material, the instrument seal being substantially perpendicular to the axis and including an instrument port wherethrough the instrument is passed; a laterally-compliant seal mounting means for mounting the instrument seal to the seal body, for forming a gas-tight seal between the instrument seal and the seal body, and for allowing the instrument seal to move freely laterally in response to lateral movement of the instrument, wherein the laterally-compliant seal mounting means includes a rigid annulus and a laterally-compliant annulus disposed between the rigid annulus and the seal body, and wherein the instrument seal is attached to the rigid annulus with the instrument port inside the annulus; and a lateral force transmitting means for transmitting a lateral force from the instrument directly to the laterally-compliant seal mounting means to move the instrument seal laterally with a reduced lateral force between the instrument and the instrument port.
Claim 3
Dependent Claim
160 words
A seal for use in a surgical instrument to provide a gas-tight seal with an instrument passed through the seal, the instrument having a diameter in a wide range of diameters, the seal comprising: a seal body including a bore wherethrough the instrument is passed, the bore defining an axis; an instrument seal of an elastic material, the instrument seal being substantially perpendicular to the axis and including an instrument port wherethrough the instrument is passed; a laterally-compliant seal mounting means for mounting the instrument seal to the seal body, for forming a gas-tight seal between the instrument seal and the seal body, and for allowing the instrument seal to move freely laterally in response to lateral movement of the instrument; and a lateral force transmitting means for transmitting a lateral force from the instrument directly to the laterally-compliant seal mounting means to move the instrument seal laterally with a reduced lateral force between the instrument and the instrument port.
Claim 4
Dependent Claim
160 words
A seal for use in a surgical instrument to provide a gas-tight seal with an instrument passed through the seal, the instrument having a diameter in a wide range of diameters, the seal comprising: a seal body including a bore wherethrough the instrument is passed, the bore defining an axis; an instrument seal of an elastic material, the instrument seal being substantially perpendicular to the axis and including an instrument port wherethrough the instrument is passed; a laterally-compliant seal mounting means for mounting the instrument seal to the seal body, for forming a gas-tight seal between the instrument seal and the seal body, and for allowing the instrument seal to move freely laterally in response to lateral movement of the instrument; and a lateral force transmitting means for transmitting a lateral force from the instrument directly to the laterally-compliant seal mounting means to move the instrument seal laterally with a reduced lateral force between the instrument and the instrument port.
Claim 5
Dependent Claim
148 words
A seal for use in a surgical instrument to provide a gas-tight seal with an instrument passed through the seal, the instrument having a diameter in a wide range of diameters, the seal comprising: a seal body including a bore wherethrough the instrument is passed, the bore defining an axis; a rigid mounting having a bore; an instrument seal of an elastic material, the instrument seal including an instrument port wherethrough the instrument is passed, being substantially perpendicular to the axis, and being attached to the rigid mounting with the instrument port over the bore of the rigid mounting; a compliant mounting disposed between the rigid mounting and the seal body; and a lateral force transmitting means for transmitting a lateral force from the instrument directly to the rigid mounting to move the instrument seal laterally with a reduced lateral force between the instrument and the instrument port.
Claim 6
Dependent Claim
148 words
A seal for use in a surgical instrument to provide a gas-tight seal with an instrument passed through the seal, the instrument having a diameter in a wide range of diameters, the seal comprising: a seal body including a bore wherethrough the instrument is passed, the bore defining an axis; a rigid mounting having a bore; an instrument seal of an elastic material, the instrument seal including an instrument port wherethrough the instrument is passed, being substantially perpendicular to the axis, and being attached to the rigid mounting with the instrument port over the bore of the rigid mounting; a compliant mounting disposed between the rigid mounting and the seal body; and a lateral force transmitting means for transmitting a lateral force from the instrument directly to the rigid mounting to move the instrument seal laterally with a reduced lateral force between the instrument and the instrument port.
Claim 7
Dependent Claim
54 words
The seal of claim 3, wherein: the lateral force transmitting means is mounted on the rigid mounting; and the lateral force transmitting means comprises plural radially-acting means, disposed about the instrument port and biassed towards the instrument port, for contacting the instrument to transmit the lateral force from the instrument to the rigid mounting.
