Laparoscopic access port for surgical instruments or the hand
A flexible, fluid-tight envelope provides access for a hand and surgical instruments through a body tissue incision while maintaining insufflation pressure or a pneumoperitoneum within the body. The envelope is transparent and has an interior volume with opposite proximal and distal ends. A first opening in the envelope at the proximal end adjoins the incision in the body tissue and is secured and sealed to the body tissue. The second opening at the envelope distal end is provided with a closure member that seals closed the second opening on itself or around the forearm of a surgeon or a surgical instrument inserted into the interior volume of the envelope.
1. A surgical apparatus for providing access to a body cavity of a patient through an incision, the apparatus comprising:
a first member having a portion configured for attachment to the patient and a first coupling disposed proximate the portion, the first member defining a passageway for accessing the body cavity through the incision, wherein the passageway has a diameter sufficient to pass a surgeon's hand;
a second member including a second coupling configured for releasable attachment to the first coupling and a flexible portion configured to extend into the passageway and surround a surgeon's arm passing through the passageway, said flexible portion comprises a sealable opening configured to receive and seal around the surgeon's arm wherein the sealable opening is configured to be seal closed in the absence of the surgeon's arm; and
wherein the portion of the first member configured for attachment to the patient is dimensioned to be inserted into the incision, and wherein the first member has axially opposite proximal and distal ends, wherein the first coupling is at the distal end and the portion for attachment to the patient is at the proximal end and comprises an annular rim that is insertable through the incision to underlie the tissue with the first member projecting through the incision to secure and seal the first member to body tissue surrounding the incision.
