摘要
A trocar includes an incision blade/safety shield cartridge assembly, a sleeve body having a distal end and an opposite proximal end, and a handle. The incision blade/safety shield cartridge assembly includes a nose cone; a stationary incision blade adapted to produce a clean incision with a flap, such as a v-shaped incision; and a retractable safety shield that conforms to the shape of the incision blade, a spring, and a safety shield spring retainer housing. The safety shield retracts to a retracted position exposing the incision blade during piercing of a body cavity and rapidly extends to an extended position beyond the tip of the incision blade upon penetration of a body cavity, thereby guarding against unintended incision and/or puncture wounds.
