Abstract
Official abstract text for this publication.
A surgical device is provided that includes a tool assembly having an anvil assembly and a cartridge assembly configured to grasp tissue therebetween, the cartridge assembly including a plurality of surgical fasteners. A motor is configured to fire one or more surgical fasteners. A sensor determines a first parameter of the tool assembly and a control system adjusts a second parameter of the motor used to fire the one or more surgical fasteners based on the first parameter detected by the sensor.
First claim
Opening claim text (preview).
What is claimed is: 1. A surgical device, comprising: a tool assembly having an anvil assembly and a cartridge assembly configured to grasp tissue therebetween, the cartridge assembly including a plurality of surgical fasteners; a motor configured to fire one or more surgical fasteners; a sensor configured to determine a first parameter of the tool assembly; and a control system configured to predict a speed at which the one or more surgical fasteners are to be fired based on the first parameter detected by the sensor. 2. The surgical device of claim 1 , wherein the first parameter is a clamp force between the anvil assembly and the cartridge assembly. 3. The surgical device of claim 2 , wherein the control system is configured to control the motor to fire the one or more staples at the predicted speed based on the clamp force. 4. The surgical device of claim 2 , wherein the control system is configured to adjust a wait time between a clamping state of the surgical device and a staple firing state of the surgical device based on the clamp force. 5. The surgical device of claim 1 , wherein the sensor is a strain gauge. 6. The surgical device of claim 1 , further comprising a display configured to display the predicted speed at which the one or more surgical fasteners are to be fired. 7. A method of stapling tissue with a surgical device having a tool assembly with a cartridge assembly and an anvil assembly and a motor configured to actuate the tool assembly, the method comprising: determining a clamp force between the cartridge assembly and the anvil assembly; predicting a speed at which one or more surgical fasteners are to be fired by the motor of the surgical device based on the clamp force. 8. The method of claim 7 , further comprising displaying the predicted speed at which the one or more surgical fasteners are to be fired by the motor of the surgical device.
