Hand access port device

Abstract

An access port device is provided which enables hand access to a patient's body cavity while retaining pneumoperitoneum by minimizing gas leakage through the access port device. The access port device comprises a sleeve of flexible material including a proximal end and a distal end, and forming an access opening positionable in an incision in a patient's body, an outer annular sealing device attached to the proximal end of the sleeve to secure the access port device externally to a patient, an inner annular sealing device attached to the distal end of the sleeve to secure the access port device internally to the patient, and an access component removably connected to the outer annular sealing device, the access component including a flexible ring removably engaging the outer annular sealing device. The access component may include a sleeved glove, an access sleeve of flexible material, the access sleeve including an integral glove for receiving a surgeon's hand, and the access sleeve and glove having a length sufficient to extend from the flexible ring through the access opening. In another aspect, the outer annular sealing device includes an annular groove for receiving the flexible ring. The annular groove may be formed in an outer peripheral surface of the outer annular sealing device. The access component may further include an access sleeve of flexible material positioned adjacent to the sleeve, the device further including an inflatable chamber formed between the sleeve and the access sleeve.
