Fluid removal in a surgical access device
First Claim
1. A surgical access device, comprising:
- a housing and a cannula extending distally from the housing, the housing and the cannula defining a working channel extending therethrough that is sized and configured to receive a surgical instrument;
a distal-most seal disposed within the housing and configured to seal the working channel when no surgical instrument is disposed therethrough; and
a scraper disposed within the housing and positioned distal of the distal-most seal and configured to remove fluid from a surgical instrument passed through the distal-most seal, sorbent positioned adjacent to the scraper, and a wicking element configured to transfer fluid from the scraper to the sorbent.

Abstract
The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. In one embodiment, a seal assembly is provided and can include a seal having an opening configured to receive a surgical instrument therethrough and a fluid remover in the form of an absorbent element, a scraper element, a wicking element, or any combination thereof can be associated with the seal and configured to remove fluid from the opening and/or a surgical instrument.

14. A surgical access device, comprising:
-
a housing having a cannula extending distally therefrom; a distal-most seal disposed within the housing and being selectively movable between an open position when an instrument is disposed therethrough and a sealed closed position when no instrument is disposed therethrough; and a fluid remover disposed within the housing proximal to the cannula and distal to the distal-most seal, the fluid remover being configured to remove fluid from a surgical instrument and to transfer the fluid to sorbent element, wherein the absorbent element includes an opening formed therethrough having a radius greater than a radius of an opening in the fluid remover such that the absorbent element does not contact a surgical instrument inserted therethrough. - View Dependent Claims (15, 16, 17)
