SURGICAL INSTRUMENT INCLUDING ELECTRICAL AND FLUID ISOLATION FEATURES

Abstract: a medical device includes an instrument shaft, a tension element guide, a tension element, and a semisolid sealing substance. the instrument shaft includes a proximal end portion, a distal end portion, and a channel between the proximal end portion and the distal end portion. the tension element guide is at the distal end of the instrument shaft, and includes a proximal seal, a distal seal, and a middle seal between the proximal seal and the distal seal. a sealing substance volume is defined between the proximal seal and the middle seal and holds the sealing substance. the tension element extends from the channel of the instrument shaft, past the proximal seal, through the sealing substance in the sealing substance volume, past the middle seal, past the distal seal, and beyond the tension element guide.
