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) is 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. |
