US 11,540,829 B2 · Surgical instrument system including replaceable end effectors

Abstract

A surgical instrument system that includes a housing and a rotatable drive shaft, a motor operably coupled to the drive shaft, and a plurality of replaceable end effectors that can be connected to the housing. Each replaceable end effector includes a drive screw that is turned a fixed number of revolutions by the motor-driven rotatable drive shaft when the end effector is connected to the housing. Each end effector further comprises a firing member operably coupled with the drive screw of the end effector. The drive screw is configured to displace the firing member over a firing length as a result of the fixed number of revolutions. In certain embodiments, each replaceable end effector can include a drive screw with a thread pitch set to the firing length divided by the fixed number of revolutions.

A system, comprising:

a hand-held surgical system, comprising:
a first distal shaft portion;
a first distal shaft connector;
a first motorized drive system;
and
a first articulation drive system;
a robotic surgical system, comprising:
a second distal shaft portion;
a second distal shaft connector;
a second motorized drive system;
and
a second articulation drive system;
and
a modular surgical instrument removably coupleable to the hand-held surgical system or the robotic surgical system, the modular surgical instrument comprising:
an end effector, comprising:
a first jaw;
a second jaw, wherein the first jaw is rotatable relative to the second jaw between an open position and a closed position;
a staple cartridge comprising staples removably stored therein;
and
a firing system, comprising:
a drive screw rotatable by the first motorized drive system of the hand-held surgical system and the second motorized drive system of the robotic surgical system;
and
a firing assembly threadably coupled to the drive screw, wherein the firing assembly is configured to be pushed distally based on rotation of the drive screw by the first motorized drive system and the second motorized drive system, and wherein the firing assembly is movable through:
a first stroke portion, wherein the firing assembly is configured to move the first jaw from the open position toward the closed position;
and
a second stroke portion, wherein the firing assembly is configured to deploy the staples from the staple cartridge and maintain the first jaw in the closed position;
an elongate shaft extending proximally from the end effector, wherein the elongate shaft comprises:
a proximal shaft portion interfaceable with the first distal shaft portion of the hand-held surgical system and the second distal shaft portion of the robotic surgical system;
a proximal shaft connector interfaceable with the first distal shaft connector of the hand-held surgical system and the second distal shaft connector of the robotic surgical system, wherein the proximal shaft connector and the first distal shaft connector are configured to couple the proximal shaft portion and the first distal shaft portion, and wherein the proximal shaft connector and the second distal shaft connector are configured to couple the proximal shaft portion and the second distal shaft portion;
and
an articulation joint;
and
an articulation system configured to rotate the end effector about the articulation joint based on articulation motions provided by the first articulation drive system of the hand-held surgical system and the second articulation drive system of the robotic surgical system;
wherein the proximal shaft connector and the first distal shaft connector are configured to:
couple the firing system to the first motorized drive system;
and
couple the articulation system to the first articulation drive system;
and
wherein the proximal shaft connector and the second distal shaft connector are configured to:
couple the firing system to the second motorized drive system;
and
couple the articulation system to the second articulation drive system.
