Injection sensor with feedback mechanism
First Claim
Patent Images
1. A surgical instrument, comprising:
- a pressure sensor; and
a support body enclosing the pressure sensor,wherein the support body includes an opening for receiving a proximal end portion of an injection instrument to secure the pressure sensor to the injection instrument such that the pressure sensor can provide a measurement indicative of a pressure exerted on a material contained within a cavity of the injection instrument during use; and
one or more electrical controllers configured to periodically sense an output from the pressure sensor disposed within the support body,wherein the support body includes a closure mechanism to close the opening in the support body such that the support body and the closure mechanism completely surround the proximal end portion of the injection instrument, andwherein the support body comprises a compressible outer wall such that application of pressure to the outer wall causes compression of the wall and transmission of force to the pressure sensor.

Abstract
The present disclosure provides devices for implanting tissue or other substances within the body. The devices can include a feedback mechanism, which can assist a surgeon in implanting the tissue or other substances by preventing excess shear force or pressure on the tissue or substance to be implanted.

10. A surgical instrument comprising:
-
a pressure sensor; and a support body enclosing the pressure sensor, wherein the support body includes a means for securing the pressure sensor to a proximal end portion of an injection instrument such that the pressure sensor can provide a measurement indicative of a pressure exerted on a material contained within a cavity of the injection instrument during use, and wherein the pressure sensor is not in fluid communication with the material contained within the cavity of the injection instrument; and one or more electrical controllers configured to periodically sense an output from the pressure sensor disposed within the support body, wherein the means for securing the pressure sensor to the proximal end portion of the injection instrument completely surrounds the proximal end portion of the injection instrument, and wherein the support body comprises a compressible outer wall such that application of pressure to the outer wall causes compression of the wall and transmission of force to the pressure sensor. - View Dependent Claims (11, 12, 14, 15, 16)
