Abstract: Surgical device (1) is for use in minimally invasive surgery using an inflated body cavity (2) accessible to a surgeon through an access port defined by a sleeve (4) passing through an incision in a patient's abdominal wall (3). The device is held in position by a distal ring (5) and a proximal ring (6). An incision engaging bladder (10) provides a first seal for engaging and retracting the incision when inflated. A second seal is provided by a self engaging bladder (12) for sealing the sleeve (4).

Abstract: Surgical device (1) is used fir in minimally invasive surgery using an inflated body cavity (2) accessible to a surgeon through an access port defined by a sleeve (4) passing through an incision in a patient's abdominal wall (3). The device is held in position by a distal ring (5) and a proximal ring (6). The device (1) is sealed by cuff valve (8), self sealing valve (18), spring valve (28) or snap open/snap shut valve (38).

Abstract: The hand access port 10 comprises a sleeve 12, having a proximal end 13 and a distal end 14. A flange 15 is located towards the distal end and is used to secure the device to a patient's body. Above the flange 15 is an inflatable chamber 16 having an entry opening 17 through which a surgeon's hand can enter. An insufflation valve 20 in provided on the outer sleeve of the chamber 16 so that the chamber can be inflated prior to the insertion of the surgeon's hand into the device. Beneath the flange 15 is the tensioning device 30 which comprises a pair of identical arcuate bands 32 which are engaged together through two orifices at each side of the edges of the inner sleeve 11 which protrudes into the patient's body. Each band is formed with a bend 40 formed in the middle with two male studs 42 at one end and two orifices 43 at the other end. The tensioning device 30 is formed by reversing two bands 42 so that the male studs 42 engage in the orifice 43 of the other band.

Abstract: An access port device (40) for use in surgery is provided which comprises a sleeve (41,42) having an exit opening located at a distal end thereof for insertion into an incision made in a patient's body, the exit opening allowing access to the patient's body cavity. The device (40) also includes exit opening sealing means for insertion into the incision. There is an entry opening located at a proximal end of the sleeve (41,42) and entry sealing means for sealing the device in the region of the entry opening, so that when the patient's body cavity is inflated by gas, the exit sealing means and the entry sealing means prevent substantial leakage of gas from the patient's body cavity while the entry sealing means also provides access for a surgeon's hand or surgical instrument and sealing about the arm remaining outside the access port device.
