Abstract
Abstract Apparatus for fixing retractors in an adjustable, predetermined position relative to a patient on an operating table. The apparatus comprises an anchor frame including a base member having at least one extension member projecting substantially perpendicular to the base member. A plurality of spaced apart, inwardly projecting anchor rings are serially arranged along the anchor frame, and a support frame, including upstanding post members is connected for supporting the base member of the anchor frame. Legs are adjustably clamped to the post members, the legs in turn being adjustably connected to the operating table. The adjustable connection of the legs to the post members is such as to clamp the post members and thus the anchor frame at a preselected and predetermined height relative to a patient on the operating table. Resilient bands are connected to preselected ones of the anchor rings, which bands include retractors thereon for separating an incision under a predetermined tension and with a predetermined opening desired by the surgeon. The purpose of this abstract is to enable the Public and the Patent Office to determine the subject matter of the technical disclosure of the application. This abstract is neither intended to define the invention of the application nor is it intended to be limiting as to the scope thereof.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
143 words
Apparatus for fixing retractors in an adjustably predetermined position relative to an operating table, said apparatus comprising: an anchor frame including a base member having at least one extension member projecting substantially perpendicular to said base member, a plurality of spaced apart, inwardly projecting anchor rings serially arranged along said anchor frame; a support frame comprising upstanding post members connected to and supporting said base member of said anchor frame; leg means, an adjustment means for adjustably connecting said leg means to said post members, and means for adjustably connecting said leg means to an operating table; said adjustment means operable to clamp said post members and thus said anchor frame at a preselected height; at least one resilient band adapted for connection of a retractor thereto; and, means for connecting said at least one resilient band to one of said anchor rings.
Claim 2
Dependent Claim
143 words
Apparatus for fixing retractors in an adjustably predetermined position relative to an operating table, said apparatus comprising: an anchor frame including a base member having at least one extension member projecting substantially perpendicular to said base member, a plurality of spaced apart, inwardly projecting anchor rings serially arranged along said anchor frame; a support frame comprising upstanding post members connected to and supporting said base member of said anchor frame; leg means, an adjustment means for adjustably connecting said leg means to said post members, and means for adjustably connecting said leg means to an operating table; said adjustment means operable to clamp said post members and thus said anchor frame at a preselected height; at least one resilient band adapted for connection of a retractor thereto; and, means for connecting said at least one resilient band to one of said anchor rings.
Claim 3
Dependent Claim
18 words
Apparatus in accordance with claim 1 including adjustable clamping means connecting said extension member to said base member.
Claim 4
Dependent Claim
23 words
Apparatus in accordance with claim 1 including a second extension member connected to said base member and spaced from said first extension member.
Claim 5
Dependent Claim
39 words
Apparatus in accordance with claim 3 including adjustable clamping means connecting said second extension member to said base member, said adjustable clamping means including means for permitting arcuate movement of said extension about the axis of said base member.
Claim 6
Dependent Claim
21 words
Apparatus in accordance with claim 1 including means for grasping said resilient bands to anchor said bands to said anchor rings.
Claim 7
Dependent Claim
11 words
Apparatus in accordance with claim 5 wherein said means comprises hemostats.
Claim 8
Dependent Claim
171 words
A surgical instrument for anchoring retractors for separating an incision and maintaining said incision in a predetermined open position, said instrument comprising: a retractor anchor frame comprising a first rigid member having a plurality of spaced apart, projecting, serially arranged anchor rings thereon; a pair of extension members having spaced apart projecting anchor rings serially arranged therealong; first and second adjustable clamping means connecting respectively said extension members in spaced apart relation to said first rigid member so as to project substantially perpendicular thereto; said clamping means including means for permitting rotation of said extension about said first rigid member and for clamping said extension in a predetermined position about said member; a support frame for said anchor frame, said support frame comprising at least one vertically oriented post connected to said first rigid member of said anchor frame, and a horizontally extending leg member adapted for connection to an operating table; and, means adjustably coupling said post to said leg and for adjusting the position of said retractor anchor frame.
Claim 9
Dependent Claim
171 words
A surgical instrument for anchoring retractors for separating an incision and maintaining said incision in a predetermined open position, said instrument comprising: a retractor anchor frame comprising a first rigid member having a plurality of spaced apart, projecting, serially arranged anchor rings thereon; a pair of extension members having spaced apart projecting anchor rings serially arranged therealong; first and second adjustable clamping means connecting respectively said extension members in spaced apart relation to said first rigid member so as to project substantially perpendicular thereto; said clamping means including means for permitting rotation of said extension about said first rigid member and for clamping said extension in a predetermined position about said member; a support frame for said anchor frame, said support frame comprising at least one vertically oriented post connected to said first rigid member of said anchor frame, and a horizontally extending leg member adapted for connection to an operating table; and, means adjustably coupling said post to said leg and for adjusting the position of said retractor anchor frame.
