摘要:
In one embodiment, a force sensing robotic surgical instrument includes a proximal housing linkable with a surgical robot arm, a shaft having a proximal portion and a distal portion, the proximal portion operably coupled to the housing, and a force transducer operably coupled to the distal portion of the shaft, the force transducer having a proximal portion, a distal portion, a plurality of radial ribs, and a strain gauge positioned over each of the plurality of radial ribs, the radial ribs forming a plurality of through passages. The instrument further includes a wrist mechanism coupled to the distal portion of the force transducer, an end effector coupled to the wrist mechanism, and a flush manifold that receives a liquid from the proximal portion of the shaft and directs the liquid along a first subset of through passages of the force transducer toward the distal portion of the force transducer. A plenum at the distal portion of the force transducer collects the liquid from the first subset of through passages and redirects the liquid back toward the proximal portion of the shaft along a second subset of through passages different from the first subset of through passages.
