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.
Claims17
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, 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.

- 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.
