Title:
経肛門的吻合リング挿入装置
Document Type and Number:
Japanese Patent JP4550946
Kind Code:
B2
Abstract:
The invention relates to a device for transanally inserting through the lower bowel one of two unitary members of a Biofragmentable Anastomosis Ring (BAR). The device comprises a curved shaft with a handle and an actuating knob at the proximal end, a nest formed at the distal end of the shaft adapted to mount a BAR carrier assembly, and a second passageway formed through the shaft that terminates at a distal open end formed through the nest. The BAR carrier assembly includes unitary male and female members that collectively comprise the BAR, male and female carriers for mounting the respective unitary member, and a collet for locking in and releasing the BAR from the BAR carrier assembly once both unitary members are secured to respective open ends of the upper and lower bowel section. The BAR Carrier Assembly is actuatable in one of three positions: open, closed, and released. Once secured to the upper bowel section, the surgeon attaches the male carrier with its attached male member to the BAR Carrier Assembly, thus placing the Assembly in the open position. The surgeon then places the BAR Carrier Assembly in the closed position by mating the male member to the female member seated in the nest. Once in the closed position, the surgeon places the BAR Carrier Assembly in the released position by actuating the insertion device and releasing the mated unitary members of the BAR from the BAR Carrier Assembly and withdrawing the insertion device from the lower bowel.
