Abstract
Abstract A device is provided which is adapted for use in surface cleaning a soiled portion of a surgical instrument. The device includes a hollow casing having an elongated slot formed in an exterior surface of the casing. The slot permits the soiled portion of the surgical instrument to be inserted into the casing interior and be moved longitudinally of the slot. A friction medium is disposed within the hollow casing and has a segment thereof aligned with the slot. The aligned segment is adapted to exert frictional force on the inserted surgical instrument portion and effect surface cleaning thereof when the instrument is moved longitudinally of the slot. The device also includes an elongated directing element which is adapted to selectively assume a first or second mode. When in the first mode, the element is exposed and aligned with the slot and is engaged by the inserted instrument portion. The engaged element controls the lateral motion of the inserted instrument portion as the latter moves longitudinally of the slot. When in the second mode, the directing element is concealed within the casing and is not accessible for engagement by the inserted instrument portion.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
147 words
A device for surface cleaning a soiled portion of a surgical instrument, comprising a hollow casing having an exposed surface provided with an elongated slot sized to accommodate and guide the soiled instrument portion when the latter is inserted through the slot and moved longitudinally thereof; directing means adapted to be exposed within said slot and extending longitudinally thereof for engagement by the inserted instrument portion and controlling lateral motion thereof as the inserted portion is moved longitudinally of the slot; friction means disposed within said casing and having a portion thereof aligned with said slot and in close proximity to said directing means, said aligned friction means adapted to be engaged by the inserted soiled instrument portion and effect surface cleaning thereof as the portion is moved longitudinally thereof; and means for retaining said directing means and friction means in predetermined relative positions within said casing.
Claim 2
Independent Claim
147 words
A device for surface cleaning a soiled portion of a surgical instrument, comprising a hollow casing having an exposed surface provided with an elongated slot sized to accommodate and guide the soiled instrument portion when the latter is inserted through the slot and moved longitudinally thereof; directing means adapted to be exposed within said slot and extending longitudinally thereof for engagement by the inserted instrument portion and controlling lateral motion thereof as the inserted portion is moved longitudinally of the slot; friction means disposed within said casing and having a portion thereof aligned with said slot and in close proximity to said directing means, said aligned friction means adapted to be engaged by the inserted soiled instrument portion and effect surface cleaning thereof as the portion is moved longitudinally thereof; and means for retaining said directing means and friction means in predetermined relative positions within said casing.
Claim 3
Dependent Claim
41 words
The device of claim 1 wherein the portion of the directing means engaged by the inserted instrument portion has a configuration whereby a swerving motion is imparted to the inserted instrument portion as the latter is moved longitudinally of the slot.
Claim 4
Dependent Claim
19 words
The device of claim 2 wherein the directing means is adapted to be straddled by the inserted instrument portion.
Claim 5
Dependent Claim
26 words
The device of claim 2 wherein the exposed surface of the casing is provided with upwardly extending guide means defining elongated peripheral segments of the slot.
Claim 6
Dependent Claim
36 words
The device of claim 1 wherein the directing means includes an elongated bail member having a segment of said bail member adapted to be slidably engaged by the inserted instrument portion and having an undulating configuration.
Claim 7
Dependent Claim
30 words
The device of claim 1 wherein the frictional means includes an elongated setose member with a central core having elongated resilient setae substantially fixed thereto and extending substantially radially therefrom.
Claim 8
Dependent Claim
28 words
The device of claim 6 wherein the directing means includes a bail member having depending support segments engaging opposite ends of the central core of the setose member.
Claim 9
Dependent Claim
89 words
The device of claim 1 wherein the frictional means and the directing means are removable as unit from the hollow casing through an access opening formed in said casing; upon reassembling the frictional means and the directing means as a unit within the casing through the access opening, the directing means may assume either a first or second mode; when in the first mode, said directing means is aligned with the casing slot, and when in the second mode, said directing means is in nonregistered relation with said slot.
Claim 10
Dependent Claim
35 words
The device of claim 1 wherein the means for retaining said directing means and friction means in predetermined relative positions within the casing includes protuberances frictionally engaging a concealed perimetric segment of the friction means.
Claim 11
Independent Claim
152 words
A device for use in surface cleaning portions of surgical instruments, such as cautery forceps, soiled with adherent liquid and non-liquid matter, comprising a hollow casing having an exposed surface provided with an elongated narrow slot sized to accommodate and guide the soiled instrument portions when the latter are inserted through the slot and moved longitudinally thereof; directing means extending longitudinally of said slot for controlling lateral motion of the inserted portions when the latter are moved longitudinally thereof; and friction means disposed within said casing and having an elongated portion thereof aligned with said slot and being accessible to the instrument portions through said slot, said friction means being in resilient engagement with segments of the casing circumjacent the slot and being adapted to exert a compressive frictional force on the inserted soiled instrument portions to effect surface cleaning thereof when the soiled instrument portions are moved longitudinally of said slot.
Claim 12
Independent Claim
152 words
A device for use in surface cleaning portions of surgical instruments, such as cautery forceps, soiled with adherent liquid and non-liquid matter, comprising a hollow casing having an exposed surface provided with an elongated narrow slot sized to accommodate and guide the soiled instrument portions when the latter are inserted through the slot and moved longitudinally thereof; directing means extending longitudinally of said slot for controlling lateral motion of the inserted portions when the latter are moved longitudinally thereof; and friction means disposed within said casing and having an elongated portion thereof aligned with said slot and being accessible to the instrument portions through said slot, said friction means being in resilient engagement with segments of the casing circumjacent the slot and being adapted to exert a compressive frictional force on the inserted soiled instrument portions to effect surface cleaning thereof when the soiled instrument portions are moved longitudinally of said slot.
Claim 13
Dependent Claim
37 words
The device of claim 10 wherein the hollow casing has an interior of a generally cylindrical cross-sectional configuration, and the exterior of said casing is provided with upwardly extending guide means defining elongated sides of the slot.
Claim 14
Dependent Claim
31 words
The device of claim 10 wherein the directing means includes a bail member having elongated surfaces adapted to be engaged by the inserted instrument portions, said surfaces having an undulating configuration.
Claim 15
Dependent Claim
87 words
The device of claim 12 wherein the bail member and friction means are removable as a unit from the hollow casing through an access opening formed therein; the bail member and friction means are reassembled as a unit with the casing through the access opening whereby the bail member may assume either a first or second mode; when in the first mode the bail member is exposed and aligned with said slot and when in the second mode is concealed and in non-registered relation with said slot.
Claim 16
Dependent Claim
19 words
The device of claim 10 wherein the friction means is formed of a synthetic or natural, resilient coarse material.
Claim 17
Dependent Claim
