  • Patent number: 11660109
    Abstract: A surgical end effector assembly includes first and second jaw members configured to grasp tissue. At least one of the jaw members defines a channel. A cutting element reciprocates through the channel to cut grasped tissue. The cutting element may include a first bevel defined along a first portion of a distal edge on a first side surface of the cutting element and a second bevel defined along a second portion of the distal edge on a second side surface of the cutting element. The first and second portions of the distal edge are sharpened to facilitate cutting tissue upon distal advancement of the cutting element. Alternatively or additionally, the cutting element may include a proximal body and a distal fin defining a height greater than a height of the proximal body and including a thinned portion defining a depression within a first side surface thereof.

  • Publication number: 20230053807
    Abstract: A surgical instrument includes a housing including an actuator disposed thereon and an elongated shaft extending therefrom. The elongated shaft includes an end effector assembly including a pair of opposing jaw members including a knife channel defined therein. An articulation section is disposed between the housing and the end effector assembly and is configured to articulate the end effector assembly upon actuation of the actuator, the articulating section and a proximal end of the knife channel defining a first distance therebetween. A knife assembly includes a knife having a length, the proximal end including an engagement feature disposed thereon. A knife drive rod is configured to engage the engagement feature to secure the knife drive rod to the knife such that the distal end of the knife extends beyond the engagement feature and wherein the knife length is less than the length of the first distance.

  • Patent number: 9293162
    Abstract: A head stack assembly (HSA) having an actuator comb with a stepped inner bore may have an upper portion of the inner bore with a first diameter that is greater than the diameter of a lower portion of the inner bore. Therefore, little friction and resistance is encountered when force fitting a pivot-bearing assembly into the upper portion of the stepped inner bore, thereby avoiding surface damage and the generation of unwanted debris particles. The HSA may further comprise a plurality of tolerance rings to couple the actuator comb with the pivot-bearing assembly, such as one tolerance ring positioned below the step feature and one tolerance ring positioned above and seated on the step feature of the comb inner bore.

  • Patent number: 7821735
    Abstract: A disk drive housing, base assembly for use as part of the housing and associated method are disclosed. The base assembly is configured for receiving a cover. In one feature, a base housing serves to define a housing interior in cooperation with the cover for receiving a plurality of components therein as part of the disk drive and the base housing includes a peripheral edge configuration. A molding surrounds and sealingly engages the base housing such that the molding defines a peripheral sealing surface for use in sealing the cover to the base assembly. In another feature, accommodating one or more given components within a given base housing outline, which would not otherwise be accommodated, is described by outsetting a peripheral sidewall of the base housing, adjacent to the given component.
