20210298813 | SYSTEMS AND METHODS OF COMMUNICATING THERMAL INFORMATION FOR SURGICAL ROBOTIC DEVICES - A medical system includes a thermal instrument, one or more processors, and memory. The medical system receives first information indicating a temperature of the thermal instrument, and receives second information indicating a distance between the thermal instrument and a secondary object. The medical system determines whether the temperature indicated by the first information satisfies a first criterion, and determines whether the distance indicated by the second information satisfies a second criterion. The medical system sends one or more signals for providing a feedback signal to a user. | 2021-09-30 |
20210298814 | JAW ASSEMBLIES FOR ELECTROSURGICAL INSTRUMENTS AND METHODS OF MANUFACTURING JAW ASSEMBLIES - A jaw assembly includes an electrically-conductive tissue-engaging structure, a jaw member including a support base, and a non-electrically conductive member including a first portion configured to engage the electrically-conductive tissue-engaging structure and a second portion configured to engage the support base of the jaw member. The non-electrically conductive member adapted to electrically isolate the electrically-conductive tissue-engaging structure from the jaw member. The electrically-conductive tissue-engaging structure and the non-electrically conductive member cooperatively define a longitudinally-oriented knife channel therethrough. | 2021-09-30 |
