Surgical instrument having force feedback capabilities
View Patent ↗A surgical instrument system is disclosed. The surgical instrument system comprises an end effector configured to be articulated between a first position and a second position, a motor configured to provide a vibratory force to a user of the surgical instrument system when the end effector moves into the first position and when the end effector moves into the second position, and a sensor. The sensor is configured to sense a first condition of the end effector when the end effector moves into the first position, sense a second condition of the end effector when the end effector moves into the second position, and send a signal to the motor indicative of the first condition and the second condition when one of the first condition and the second condition is sensed. The signal comprises one of the group consisting of a square wave signal and a sine wave signal.
1. A surgical instrument system, comprising:
a handle assembly;
a shaft extending from said handle assembly and defining a shaft axis;
an articulation joint;
an end effector attached to said shaft by way of said articulation joint, wherein said end effector is configured to be articulated relative to said shaft axis between a first position and a second position, said end effector comprising:
a first jaw;
a second jaw movable relative to said first jaw;
a staple cartridge comprising a plurality of staples removably stored within said staple cartridge, wherein said staples are configured to be ejected from said staple cartridge; and
an anvil configured to deform said staples;
a motor configured to provide a vibratory force to a user of said surgical instrument system through said handle assembly to signal the user when said end effector moves into said first position and when said end effector moves into said second position; and
a sensor configured to:
sense a first condition of said end effector when said end effector moves into said first position;
sense a second condition of said end effector when said end effector moves into said second position; and
send a signal to said motor indicative of said first condition and said second condition when one of said first condition and said second condition is sensed, wherein said signal comprises one of the group consisting of a square wave signal and a sine wave signal.
2. The surgical instrument system of claim 1 , wherein said first position is indicative of an articulation limit of said end effector.
3. The surgical instrument system of claim 1 , wherein said vibratory force comprises a variable force.
4. The surgical instrument system of claim 1 , wherein articulation of said end effector is actuated by said motor.
5. The surgical instrument system of claim 1 , wherein said second jaw comprises said anvil.
6. A surgical instrument system, comprising:
a handle assembly;
a shaft extending from said handle assembly and defining a shaft axis;
an articulation joint, wherein said articulation joint defines an articulation axis which is transverse to said shaft axis;
an end effector attached to said shaft by way of said articulation joint, wherein said end effector is configured to be articulated relative to said shaft axis between a first position and a second position, said end effector comprising:
a first jaw;
a second jaw movable relative to said first jaw;
a staple cartridge comprising a plurality of staples removably stored within said staple cartridge, wherein said staples are configured to be ejected from said staple cartridge; and
an anvil configured to deform said staples;
a tactile feedback system configured to provide tactile feedback to a user of said surgical instrument system through said handle assembly when said end effector assumes said first position and when said end effector assumes said second position; and
a sensor configured to:
sense a first state of said end effector when said end effector moves into said first position;
sense a second state of said end effector when said end effector moves into said second position; and
send a signal to said tactile feedback system indicative of said first state and said second state when one of said first state and said second state is sensed, wherein said signal comprises one of the group consisting of a square wave signal and a sine wave signal.
7. The surgical instrument system of claim 6 , wherein said first position is indicative of an articulation limit of said end effector.
8. The surgical instrument system of claim 6 , wherein said tactile feedback comprises a vibratory force.
9. The surgical instrument system of claim 8 , wherein said vibratory force comprises a variable force.
10. The surgical instrument system of claim 6 , wherein said tactile feedback system comprises a motor, and wherein articulation of said end effector is actuated by said motor.
11. The surgical instrument system of claim 6 , wherein said second jaw comprises said anvil.
