A drive mechanism for an endoscopic surgical instrument which has a rotatable drive shaft and a mechanism for translating the rotational force of the shaft for applying fasteners to tissue during endoscopic surgery.
An instrument for applying fasteners to tissue during endoscopic surgery, said instrument comprising a handle portion for manipulation outside a body of a mammal, means comprising a business head for applying a fastener to tissue within the body of said mammal; and a housing portion connecting said
An instrument for applying fasteners to tissue during endoscopic surgery, said instrument comprising a handle portion for manipulation outside a body of a mammal, means comprising a business head for applying a fastener to tissue within the body of said mammal; and a housing portion connecting said handle portion to said business head, said housing portion and said business head insertable into said mammal endoscopically through a trocar cannula, said housing portion having a rotatable drive shaft disposed therein and extending from said handle portion to said business head, said drive shaft being torsionally stiff to generate sufficient force to drive a fastener through tissue and apply said fastener to the tissue, and means disposed in said business head for translating the rotational forces of the drive shaft into non-rotational forces for applying said fastener and wherein the means disposed in said business head for translating the rotational forces of the drive shaft into non-rotational forces translates said rotational forces into reciprocating forces for applying said fastener.
