Abstract
Abstract A percutaneous surgical system includes a plurality of tissue retractors configured to maintain a working space within soft tissue. The tissue retractors include a prong on their inner surfaces for engaging a ring member. The ring member maintains the position of the tissue retractors while also defining a number of channels inside the ring member. In one embodiment, the ring member includes concentric inner and outer walls connected by support walls. The inner wall defines an inner bore for supporting a working channel sleeve for the introduction of working instruments. A plurality of outer channels are defined between the inner, outer and support walls for the introduction of ancillary instruments to the surgical site. A manipulation tool is also provided that engages each tissue retractor for positioning the retractor within the patient.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
79 words
A tissue retractor comprising: an elongated blade having a proximal end, a distal end, and a length therebetween, said distal end configured for atraumatic contact with body tissue, said blade defining a channel along said length, said channel configured to receive an elongated pin therethrough; and a prong attached to said blade between said proximal and distal ends, said prong defining a slot between said blade and said prong, said slot opening toward said proximal end of said blade.
Claim 2
Dependent Claim
79 words
A tissue retractor comprising: an elongated blade having a proximal end, a distal end, and a length therebetween, said distal end configured for atraumatic contact with body tissue, said blade defining a channel along said length, said channel configured to receive an elongated pin therethrough; and a prong attached to said blade between said proximal and distal ends, said prong defining a slot between said blade and said prong, said slot opening toward said proximal end of said blade.
Claim 3
Dependent Claim
40 words
The tissue retractor according to claim 1 , wherein said elongated blade includes a first portion extending from said proximal end and a second portion extending from said distal end, said second portion being angled relative to said first portion.
Claim 4
Dependent Claim
31 words
The tissue retractor according to claim 2 , wherein said elongated blade includes a first side and opposite second side, and said second portion being angled away from said first side.
Claim 5
Dependent Claim
17 words
The tissue retractor according to claim 3 , wherein said prong is attached to said first side.
Claim 6
Dependent Claim
40 words
The tissue retractor of claim 3 , wherein said channel is defined by a tube attached to said second side and extending along substantially the entire length of said first portion and intersecting said second side of said second portion.
Claim 7
Dependent Claim
22 words
The tissue retractor of claim 1 , wherein said channel extends between said proximal end and said distal end of said blade.
Claim 8
Dependent Claim
31 words
The tissue retractor of claim 6 , further comprising a fixation pin having a length greater than the length of said elongated blade and sized to be received within said channel.
Claim 9
Dependent Claim
25 words
The tissue retractor assembly according to claim 7 , wherein said fixation pin has a tip configured for penetrating bone to anchor said fixation pin.
Claim 10
Dependent Claim
116 words
A tissue retractor comprising: an elongated blade having a proximal end, a distal end, and a length therebetween, said distal end configured for atraumatic contact with body tissue, said blade having a channel for receiving a fixation pin therethrough; a plate portion attached to said blade and projecting outwardly from said proximal end; a boss projecting from said plate portion and defining a groove around at least a portion of said boss, wherein said boss includes: a base attached to said plate portion; and a disc attached to said base, wherein said groove is defined at an intersection of said base and said disc, said disc including a plurality of notches for engaging a manipulation tool.
Claim 11
Dependent Claim
116 words
A tissue retractor comprising: an elongated blade having a proximal end, a distal end, and a length therebetween, said distal end configured for atraumatic contact with body tissue, said blade having a channel for receiving a fixation pin therethrough; a plate portion attached to said blade and projecting outwardly from said proximal end; a boss projecting from said plate portion and defining a groove around at least a portion of said boss, wherein said boss includes: a base attached to said plate portion; and a disc attached to said base, wherein said groove is defined at an intersection of said base and said disc, said disc including a plurality of notches for engaging a manipulation tool.
Claim 12
Dependent Claim
67 words
The tissue retractor according to claim 9 , wherein said elongated blade includes a first portion extending from said proximal end and a second portion extending from said distal end, said second portion being angled relative to said first portion, and further wherein said channel extends substantially the entire length of said first portion and intersects said second portion to define an opening through said second portion.
Claim 13
Dependent Claim
65 words
The tissue retractor according to claim 10 , wherein said elongated blade includes a first side and opposite second side, said second portion being angled away from said first side, and further wherein said channel is defined by a tube attached to said second side and extending along substantially the entire length of said first portion and intersecting said second side of said second portion.
Claim 14
Dependent Claim
43 words
The tissue retractor according to claim 9 , further comprising a prong attached to said blade between said proximal and distal ends, said prong defining a slot between said blade and said prong, said slot opening toward said proximal end of said blade.
Claim 15
Dependent Claim
22 words
The tissue retractor of claim 9 , wherein said channel extends between said proximal end and said distal end of said blade.
Claim 16
Dependent Claim
31 words
The tissue retractor of claim 13 , further comprising a fixation pin having a length greater than the length of said elongated blade and sized to be received within said channel.
Claim 17
Dependent Claim
25 words
The tissue retractor assembly according to claim 14 , wherein said fixation pin has a tip configured for penetrating bone to anchor said fixation pin.
