Abstract

An anoscope kit includes an anoscope having a plurality of spaced apart fingers having free ends and a dilator removably positionable within the anoscope to aid insertion of the anoscope. The dilator has a proximal region, an intermediate region and a distal region. The distal region includes an enlarged distal head. A ramped surface extends from the enlarged distal head toward the intermediate region. The intermediate region has an outer surface to contact the fingers of the dilator.

Claims (25)

1. An anoscope defining a central longitudinal axis and comprising:

a flange having a cannulated, disc-shaped configuration, the flange being configured to prevent full insertion of the anoscope into an anal canal; and

a plurality of spaced apart fingers extending distally from the flange, each finger of the plurality of spaced apart fingers including:

an inner surface;

an outer surface; and

a distal tip having an angled surface extending from the inner surface to the outer surface that tapers away from the central longitudinal axis in a distal direction, wherein the angled surface of the distal tip of each finger is planar.

2. The anoscope of claim 1 , wherein the flange is configured to receive a dilator.

3. The anoscope of claim 1 , wherein each finger of the plurality of spaced apart fingers further includes a proximal portion extending in parallel relation to the central longitudinal axis.

4. The anoscope of claim 1 , wherein adjacent fingers of the plurality of spaced apart fingers define gaps, each gap extending longitudinally from the flange to the distal tip of each respective finger of the plurality of spaced apart fingers.

5. The anoscope of claim 1 , wherein the plurality of spaced apart fingers is configured to flex outwardly relative to the central longitudinal axis upon receipt of a dilator within the anoscope.

6. A surgical system, comprising:

an anoscope defining a central longitudinal axis and including:

a flange having a cannulated, disc-shaped configuration, the flange being configured to prevent full insertion of the anoscope into an anal canal; and

a plurality of spaced apart fingers extending distally from the flange, each finger of the plurality of spaced apart fingers including:

an inner surface;

an outer surface; and

a distal tip having an angled surface extending from the inner surface to the outer surface that tapers away from the central longitudinal axis in a distal direction, wherein the angled surface of the distal tip of each finger is planar; and

a dilator configured to be received through the flange, the dilator having a surface positioned to be in abutment with the angled surface of each finger of the plurality of spaced apart fingers of the anoscope upon receipt of the dilator in the anoscope.

7. The surgical system of claim 6 , wherein the surface of the dilator tapers toward a central longitudinal axis of the dilator in a proximal direction.

8. The surgical system of claim 7 , wherein the dilator further includes:

an intermediate portion; and

an enlarged distal head disposed distally of the intermediate portion, wherein the surface of the dilator is a transition surface interposed between the intermediate portion and the enlarged distal head.

9. The surgical system of claim 6 , wherein each finger of the plurality of spaced apart fingers further includes a proximal portion extending in parallel relation to the central longitudinal axis.

10. The surgical system of claim 6 , wherein adjacent fingers of the plurality of spaced apart fingers define gaps, each gap extending longitudinally from the flange to the distal tip of each respective finger of the plurality of spaced apart fingers.

11. The surgical system of claim 6 , wherein the plurality of spaced apart fingers is configured to flex outwardly relative to the central longitudinal axis upon receipt of the dilator within the anoscope.
