Abstract
A device and method in accordance with the invention for generating a signal indicative of a property of a subject tissue in contact with the working surface of a surgical instrument. The invention describes a sensing adjunct to surgical staplers. The adjunct can take the form of an optionally coupled accessory to a surgical stapler, or a stand-alone substitutive component acting to serve as a replacement for a component of the surgical stapler such as an anvil, housing or cartridge. Embodiments include a sensing anvil serving to act in place of a non-sensing surgical stapler anvil to monitor tissue properties of an anastomosis for the purpose of avoiding anastomotic failure.
Claims42
A self contained adjunct sensing system configured to be detachably coupled to a surgical stapler, the adjunct sensing system comprising:
- an adjunct housing configured to be detachably coupled to the surgical stapler;
- wherein the adjunct housing maintains
- at least one sensor configured to sense at least one property of tissue and an interaction with tissue;
- a processor configured to receive and process signals from said at least one sensor;
- and
- a communications interface configured to transfer information at least one of to and from the processor.
An adjunct configured to be detachably coupled with a surgical stapler, the adjunct comprising:
- an adjunct housing configured to be detachably coupled to the surgical stapler;
- a self contained sensing system, the sensing system including
- at least one sensor;
- a processor configured to receive and process signals from said at least one sensor;
- and
- a communications interface configured to transfer information at least one of to and from the processor;
- and
- wherein the self contained sensing system is maintained by the adjunct housing.
A surgical assembly comprising:
- a device for creating an anastomosis;
- and
- an adjunct maintained by an adjunct housing, the adjunct housing configured to be removably coupled with the device, the adjunct comprising a self contained sensing system configured to sense at least one of a physiologic property of tissue and a mechanical property of tissue using a sensor, process signals related to said sensed tissue properties using a processor, and transfer information related to at least one of said sensed tissue properties and said processed signals using a communications interface.
