Abstract

A wound protector and retractor device comprising a longitudinal axis, a distal member, a proximal member, and a sleeve extending at least between the distal member and the proximal member. The sleeve has a proximal gripping portion for pulling the sleeve upwardly to shorten an axial extent located between the distal member and the proximal member.

Claims

1. A wound protector and retractor device comprising:

a longitudinal axis;

a distal member;

a proximal member; and

a sleeve extending at least between the distal member and the proximal member,

the sleeve having a proximal gripping portion for pulling the sleeve upwardly to shorten an axial extent located between the distal member and the proximal member.

2. A wound protector and retractor device as claimed in claim 1 wherein, on release of the gripping portion the shortened axial extent between the distal member and the proximal member is substantially maintained without a requirement for an additional locking device.

43. A wound protector and retractor device as claimed in claim 1 wherein the device comprises a first proximal mounting member and a second proximal mounting member between which at least portion of a sleeve extends.

44. A wound protector and retractor device as claimed in claim 43 wherein the first and second mounting members are movable relative to one another.

45. A wound protector and retractor device as claimed in claim 44 wherein the mounting members are movable axially relative to one another.

61. A wound protector and retractor device as claimed in claim 1 further including a valve.

62. A wound protector and retractor device as claimed in claim 61 wherein the valve is attached to the device.

63. A wound protector and retractor device as claimed in claim 62 wherein the valve is attached to the proximal portion of the sleeve.

64. A wound protector and retractor device as claimed in claim 62 wherein a connector is provided between the device and the valve.

65. A wound protector and retractor device as claimed in claim 64 wherein the connector comprises a connector sleeve.

66. A wound protector and retractor device as claimed in claim 65 wherein the connector sleeve is of substantially fixed length.

67. A wound protector and retractor device as claimed in claim 62 wherein a flexible joint is provided between the valve and the device.

68. A wound protector and retractor device as claimed in claim 62 wherein a malleable joint is provided between the valve and the device.

69. A wound protector and retractor device as claimed in claim 68 wherein the valve is offset with respect to the longitudinal axis of the wound retractor.

81. A wound protector and retractor device comprising:

a longitudinal axis;

a distal member;

a proximal member; and

a sleeve extending at least between the distal member and the proximal member,

the sleeve, on retraction of an incision, defining an excess sleeve portion extending proximally from the proximal member.

82. A wound protector and retractor device as claimed in claim 81 wherein the excess sleeve portion is configured to form a seal.

83. A wound protector and retractor device as claimed in claim 82 wherein the seal is a forearm seal.

84. A wound protector and retractor as claimed in claim 82 wherein the seal is an instrument seal.

85. (canceled)

86. A wound protector and retractor device comprising:

a longitudinal axis;

a distal member;

a proximal member; and

a sleeve extending at least between the distal member and the proximal member,

the device further comprising a first proximal mounting member and a second proximal mounting member between which at least portion of a sleeve extends.

87. A wound protector and retractor device as claimed in claim 86 wherein the first and second mounting members are movable relative to one another.
