Abstract
Abstract A device which stabilizes the sheath of an endoscope or arthroscope during surgery. The device is a relatively thin, flat, flexible plate of plastic material and is adapted to be placed against a patient's body at the area where penetration is made by the scope sheath. The plate is formed with a predetermined sized central hole and the sheath is slidably inserted through the hole and has an interference fit with the surrounding plate material. The plate provides a stable base for the scope to be slidably moved with respect to the plate to adjust the depth of penetration. The plate preferably has a bow or generally figure-eight configuration which provides sufficient surface area at both ends of the plate to provide a stable base for the scope while permitting other surgical instruments to be inserted into the patient's body closely adjacent the scope due to the concavity of the plate sides. Various mechanisms can be mounted in the central plate hole to accommodate various sizes of scope sheaths.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
88 words
A device for stabilizing a sheath of an endoscope or arthroscope during surgery including a plate formed of a flexible plastic material adapted to be placed against the patient's body at an area where the sheath penetrates the body; a camming stud rotatably mounted on the plate; and a tapered hole formed in the plate adjacent the camming stud for receiving the sheath extending therethrough during surgery with the camming stud being rotatable into engagement with the sheath to retain and hold said sheath within said tapered hole.
Claim 2
Independent Claim
88 words
A device for stabilizing a sheath of an endoscope or arthroscope during surgery including a plate formed of a flexible plastic material adapted to be placed against the patient's body at an area where the sheath penetrates the body; a camming stud rotatably mounted on the plate; and a tapered hole formed in the plate adjacent the camming stud for receiving the sheath extending therethrough during surgery with the camming stud being rotatable into engagement with the sheath to retain and hold said sheath within said tapered hole.
Claim 3
Independent Claim
126 words
A device for stabilizing a sheath of an endoscope or arthroscope during surgery including a plate formed of a flexible plastic material adapted to be placed against the patient's body at an area where the sheath penetrates the body; opening means formed in the plate for receiving and holding the sheath extending therethrough during surgery; said opening means including an adjustable opening forming member mounted on the plate having an externally threaded projection, an end cap threadably engaged with said projection, and a soft deformable member located between the projection and end cap and having a central opening adapted to receive the sheath therein whereby axially movement of the end cap on the projection compresses the deformable member expanding it into clamping engagement with the sheath.
Claim 4
Independent Claim
126 words
A device for stabilizing a sheath of an endoscope or arthroscope during surgery including a plate formed of a flexible plastic material adapted to be placed against the patient's body at an area where the sheath penetrates the body; opening means formed in the plate for receiving and holding the sheath extending therethrough during surgery; said opening means including an adjustable opening forming member mounted on the plate having an externally threaded projection, an end cap threadably engaged with said projection, and a soft deformable member located between the projection and end cap and having a central opening adapted to receive the sheath therein whereby axially movement of the end cap on the projection compresses the deformable member expanding it into clamping engagement with the sheath.
Claim 5
Dependent Claim
32 words
The stabilizing device defined in claim 2 in which the plate is generally flat and sufficiently thin to provide some flexibility thereto; and in which said plate has a generally figure-eight configuration.
Claim 6
Dependent Claim
21 words
The stabilizing device defined in claim 3 in which the longitudinal length of the plate is approximately twice its maximum width.
Claim 7
Dependent Claim
27 words
The stabilizing device defined in claim 4 in which the plate has a longitudinal length of approximately 41/2 inches and a maximum width of approximately 21/4 inches.
Claim 8
Dependent Claim
30 words
The stabilizing device defined in claim 3 in which the plate is formed of a low density polyurethane with a thickness within a range of between 0.05 and 0.10 inches.
Claim 9
Dependent Claim
32 words
The stabilizing device defined in claim 2 in which a pressure sensitive adhesive is applied to a surface of the plate for removably attaching the plate to the body of a patient.
