End-effector force measurement drive circuit

摘要

END-EFFECTOR FORCE MEASUREMENT DRIVE CIRCUIT A surgical instrument (1110) for applying fasteners includes a drive motor (1150), a replaceable loading unit (1114) having an end-effector assembly (1111), and an adapter (1120) configured to releaseably couple a replaceable loading unit (1114) to the drive motor (1150). The adapter (1120) includes a strain gauge (1122) having a drive circuit (29) coupled thereto. The strain gauge (1122) and the drive circuit (29) are configured to directly measure a driving force in the adapter (1120). 43 40 4 b 30 40b 40a 37a 38 37b 39 40b
