  • Patent number: 11103244
    Abstract: A surgical instrument includes a body, a shaft, and an end effector that is operable to compress, staple, and cut tissue. The end effector includes a pair of jaws. One of the jaws has a greater thickness than the other. On the thicker jaw is a placement tip that is elastically deformable from a biased curved position when the tip is subject to a force, such as the force exerted when tissue is clamped between the jaws. The placement tip extends distally from the distal end of the jaw to which it is attached. The placement tip can have a variety of shapes. The placement tip is made of a material having a lower stiffness than the material of the jaw from which the placement tip extends.

    Abstract: A surgical clip applier includes a counter assembly including a counting wheel with a plurality of actuation features, a locking spring assembly, a driver, and a pin assembly. The counting wheel includes indicia visible through the handle assembly. The locking spring assembly is positioned within the counting wheel and is configured to prohibit multidirectional rotation of the counting wheel. The driver includes a grasping protrusion and a positioning protrusion. The driver translates between a proximal position and a distal position, wherein the grasping protrusion engages the plurality of actuation features to rotate the counting wheel to change the indicia. The pin assembly is configured to engage with the positioning protrusion of the driver, wherein during transitioning of the driver from the proximal position to the distal position, the positioning protrusion engages the stationary pin to pivot the driver, whereby the driver disengages from the plurality of actuation features.

  • Patent number: 10660725
    Abstract: A counter assembly is supported in a handle assembly of a clip applier. The counter assembly includes a counting mechanism, a ratchet mechanism, and an actuator. The counting mechanism is positioned to rotate within the handle assembly and includes indicia visible through the handle assembly. The ratchet mechanism is rotationally coupled to the counting mechanism and prohibits multidirectional rotation of the counting mechanism. The actuator includes a protrusion projecting therefrom. The actuator is positioned to translate between a proximal position and a distal position, wherein the protrusion of the actuator engages the counting mechanism to rotate the counting mechanism, in a first direction, to adjust the indicia of the counting mechanism, which is visible through the handle assembly. In the proximal position, the protrusion of the actuator is disposed proximal of the counting mechanism. In the distal position, the protrusion of the actuator is disposed distal of the counting mechanism.

  • Patent number: 10646230
    Abstract: Release mechanism for medical device includes a bushing having a proximal end, a distal end and a channel extending therethrough. Plurality of extend proximally from the distal end are biased toward a release configuration in which engagement surfaces at distal ends thereof retract radially into the channel. A core pin insertable through the channel applies a radially expansive pressure to move the arms radially outward to a locking configuration. Engagement surfaces of the first and second arms connect to a retaining surface of a tissue treatment device containing capsule, which extends at an angle relative to the engagement surfaces selected so that a first portion of a force transmitted along an axis of the bushing moves the arms radially inward toward the release configuration before a second portion of the force exceeds a threshold level associated with the removal of a tissue treatment device from gripped tissue.
