SURGICAL STAPLER HAVING HAPTIC FEEDBACK
First Claim
1. A surgical tool system comprising:
- a surgical tool operable to staple tissue, the tool including a distal portion including a tissue stapling mechanism connected to a handle via a shaft;
a sensor coupled to the surgical tool, wherein the sensor is configured to monitor a tissue property;
a control system electrically connected to sensor, wherein the control system calculates sensor information from signals received from the sensor and processes the sensor information into signal commands; and
a feedback system including one or more haptic actuators coupled to the handle and electrically connected to the control system, wherein the control system communicates the signal commands to the feedback system and the feedback system uses the signal commands to generate haptic feedback relating to the sensor information to the handle.

Abstract
A surgical tool system includes a surgical tool for cutting and stapling tissue and a tactile feedback system integrated onto a handle of the tool that generates relevant feedback in at least the form of haptic effects to the user. The tactile feedback alerts the user of tissue properties, i.e., the type of tissue or other structures located within the jaws of the stapler, whether the quantity or thickness of tissue located within the jaws of the stapler is appropriate for the selected stapler cartridge, whether the proper length of staples has been fired based on the length of tissue located in the jaws, whether a blood vessel is located within the jaws of the stapler, whether the stapling process has successfully sealed the tissue located within the jaws of the stapler, the position of the cutting element, and/or when the stapling procedure or firing cycle is completed.

12. A method of providing feedback to a user during a tissue stapling surgical procedure, the method comprising the steps of:
-
monitoring a tissue property during the tissue stapling surgical procedure via at least one sensor mounted on a distal portion of a surgical tool; processing the sensor information; and communicating haptic feedback to a handle of the surgical tool, wherein the haptic feedback relates to the sensor information. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
