Abstract
Abstract An inexpensive, lightweight apparatus and method is provided for removing coagulum and other debris from the tip of cautery blades and needles during use and for holding cautery blades and needles when not in use. The cleaner comprises a pad having a lower compressible portion and an upper fibrous abrasive portion which is mounted to a hard, non-compressible base. The apparatus can be attached to a surgical drape or other accessible surface to permit cleaning using only one hand to manipulate the cauterizing instrument. Cautery tips and other sharp surgical instruments are cleaned by plunging them into, and then withdrawing them from, the abrasive pad. The pad also provides a convenient structure for holding cautery tips and other sharp surgical instrument in a point down, base up configuration when the instruments are not in use.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
156 words
A method for cleaning surgical cautery tips using a cautery tip cleaner comprising a relatively thick sterilizable, compressible pad mounted on a substantially non-compressible, puncture resistant base having a means for attaching the cautery tip cleaner to a surface within easy reach of a user, said compressible pad including a upper fibrous abrasive portion having a top surface, said upper fibrous abrasive portion being sufficiently thick so that if a cautery tip is pushed into said abrasive portion and withdrawn, any coagulum or debris attached to said tip will be substantially removed by the fibrous abrasive material, said method comprising: attaching the cautery tip cleaner to a surface within easy reach of a user; pushing the point of the cautery tip through the top surface of the upper fibrous abrasive portion and well into the compressible pad of the cautery tip cleaner; and, withdrawing the cautery tip from the compressible pad of the cautery tip cleaner.
Claim 2
Independent Claim
156 words
A method for cleaning surgical cautery tips using a cautery tip cleaner comprising a relatively thick sterilizable, compressible pad mounted on a substantially non-compressible, puncture resistant base having a means for attaching the cautery tip cleaner to a surface within easy reach of a user, said compressible pad including a upper fibrous abrasive portion having a top surface, said upper fibrous abrasive portion being sufficiently thick so that if a cautery tip is pushed into said abrasive portion and withdrawn, any coagulum or debris attached to said tip will be substantially removed by the fibrous abrasive material, said method comprising: attaching the cautery tip cleaner to a surface within easy reach of a user; pushing the point of the cautery tip through the top surface of the upper fibrous abrasive portion and well into the compressible pad of the cautery tip cleaner; and, withdrawing the cautery tip from the compressible pad of the cautery tip cleaner.
Claim 3
Dependent Claim
161 words
A surgical cautery tip cleaner and holder for cleaning surgical cautery tips and other sharp surgical instruments and for holding cautery tips and other surgical instruments in a point down, base up configuration comprising: a hard base having a bottom surface and a top surface, said base being resistant to penetration by needles or other sharp objects; a relatively thick compressible pad mounted on the top surface of the hard base and having an upper fibrous abrasive portion and a lower compressible portion, said upper abrasive portion having a top surface and sufficient thickness to clean a cautery tip when the point of the cautery tip is plunged from the top surface well into the pad and withdrawn, said compressible pad having sufficient thickness to support a plurality of cautery tips in a point down, base up configuration when such tips are plunged into the pad and released; said base and said compressible pad being constructed from materials suitable for sterilizing.
Claim 4
Dependent Claim
161 words
A surgical cautery tip cleaner and holder for cleaning surgical cautery tips and other sharp surgical instruments and for holding cautery tips and other surgical instruments in a point down, base up configuration comprising: a hard base having a bottom surface and a top surface, said base being resistant to penetration by needles or other sharp objects; a relatively thick compressible pad mounted on the top surface of the hard base and having an upper fibrous abrasive portion and a lower compressible portion, said upper abrasive portion having a top surface and sufficient thickness to clean a cautery tip when the point of the cautery tip is plunged from the top surface well into the pad and withdrawn, said compressible pad having sufficient thickness to support a plurality of cautery tips in a point down, base up configuration when such tips are plunged into the pad and released; said base and said compressible pad being constructed from materials suitable for sterilizing.
Claim 5
Dependent Claim
26 words
The cautery tip cleaner and holder of claim 2 additionally comprising a means for attaching the base to a surface within easy reach of a user.
Claim 6
Dependent Claim
31 words
The cautery tip cleaner and holder of claim 3 in which said means for attaching the base to a surface comprises adhesive attached to the bottom surface of the hard base.
Claim 7
Dependent Claim
31 words
The cautery tip cleaner and holder of claim 2 in which said compressible pad also contains a depression for holding surgical instruments in a generally horizontal orientation when not in use.
Claim 8
Dependent Claim
31 words
The cautery tip cleaner and holder of claim 2 in which the upper fibrous abrasive portion and lower compressible portion of the compressible pad are both comprised of fibrous, abrasive material.
Claim 9
Dependent Claim
118 words
The cautery tip cleaner and holder of claim 2 in which said upper fibrous abrasive portion additionally contains one or more elongated slits which penetrate the surface of the upper fibrous abrasive portion and which have a first end, a second end, opposing abrasive walls and an abrasive floor for cleaning a cautery blade having two sides and an edge by pressing the edge of the blade down between any two opposing abrasive walls at the first end deforming the floor and compressing the lower compressible portion to bring the opposing abrasive walls together against the sides of the cautery blade and then drawing the blade through the slit towards the second end to clean the cautery blade.
Claim 10
Independent Claim
