Benefits of technology

[0014]The method may also include the step of providing an indication of a status of a tissue gap range. The tissue property may be detected by measuring the current draw on the motor or measuring a dwell effect at the end effector.

Problems solved by technology

If the clamping structures of the instrument are exposed to excessive force, maintaining a uniform target tissue gap across the length of tissue to be stapled may be difficult or even impossible.
This high level of pressure may result in excess tissue trauma.

Abstract

A surgical instrument is provided including an end effector configured to clamp, staple or cut tissue tissue, a motor configured to drive the end effector and a control system. The control system is configured to receive information about at least one tissue property and select a tissue management mode based on the at least one tissue property. The control system controls the motor based on the selected tissue management mode.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims the benefit of and priority to U.S. Provisional Application Ser. No. 61 / 445,700, filed on Feb. 23, 2011, the entire contents of which are incorporated herein by reference.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates generally to medical devices. More specifically, the present disclosure relates generally to systems and methods for controlled tissue compression.[0004]2. Background of the Related Art[0005]Some surgical procedures require the compression, e.g., clamping, of a patient's tissue. Such procedures may include, e.g., anastomosing, stapling, and resecting of tissue. For example, where cancerous tissue is identified in a patient's gastrointestinal tract, the cancerous tissue may need to be surgically removed. Where, for example, the cancerous tissue is located on the colon and is accessible by surgical instrumentation, the surgeon may make an incision in the patient's abdomen t...
