Abstract
A clip applier is provided for applying a surgical clip to tissue. The clip applier may include a first jaw member that engages a first distal portion of the surgical clip, and a second jaw member that engages a second distal portion of the surgical clip. The first and second jaw members move relative to each other between an open configuration and a closed configuration. A first longitudinal channel extends through a first inner portion of the first jaw member and separates the first jaw member into a pair of first extensions. A first stabilizing member has a first distal end portion fixedly secured to the first jaw member inside of the first longitudinal channel, and a first proximal end portion that engages a first proximal portion the surgical clip to reduce movement of the surgical clip.
Core Innovation
A clip applier is configured to apply a surgical clip to tissue using first and second jaw members that move relative to each other between an open configuration and a closed configuration. Each jaw member engages a distal portion of the surgical clip, and each jaw member includes a longitudinal channel extending through an inner portion and separating the jaw member into extensions.
A first stabilizing member has a first distal end portion secured to the first jaw member inside of the first longitudinal channel and a first proximal end portion configured to engage a proximal portion of the surgical clip to reduce movement. A second stabilizing member has a second distal end portion secured to the second jaw member inside of the second longitudinal channel and a second proximal end portion configured to engage the proximal portion of the surgical clip to reduce movement.
The stabilizing members are configured to compress and/or pivot proximally as the jaw members move from the open configuration to the closed configuration to close the surgical clip. In the open configuration, the first proximal end portion is spaced apart from the second proximal end portion, and in the closed configuration the first proximal end portion contacts the second proximal end portion.
The disclosed arrangements include embodiments where the stabilizing members flex and stabilize the clip during endoscopic/open ligation, including flexible stabilizing members that provide additional vertical and lateral stability.
Claims Coverage
The only independent claim identified is clm-00001. It requires a clip applier structure with first and second longitudinal channels containing first and second stabilizing members, where the stabilizing members reduce clip movement and compress and/or pivot proximally during closure, with spaced proximal portions in the open configuration and contact in the closed configuration.
Clip applier with paired jaw members and longitudinal channels for clip stabilization
A first jaw member and a second jaw member move between an open configuration and a closed configuration to engage distal portions of the surgical clip, with a first longitudinal channel through an inner portion of the first jaw member and a second longitudinal channel through an inner portion of the second jaw member, each longitudinal channel separating the jaw member into extensions.
Distal-secured flexible stabilizing members in longitudinal channels
A first stabilizing member with a first distal end portion secured inside the first longitudinal channel and a first proximal end portion configured to engage a proximal portion of the surgical clip to reduce movement, and a second stabilizing member with a second distal end portion secured inside the second longitudinal channel and a second proximal end portion configured to engage the proximal portion to reduce movement.
Compressing and/or pivoting proximal stabilizing action during clip closure
The first and second stabilizing members are configured to compress and/or pivot proximally as the first and second jaw members move from the open configuration to the closed configuration to close the surgical clip.
Separated proximal stabilizer ends in open state and contact in closed state
The first proximal end portion of the first stabilizing member is spaced apart from the second proximal end portion of the second stabilizing member when the jaw members are in the open configuration; the first proximal end portion contacts the second proximal end portion when the jaw members are in the closed configuration.
Independent claim clm-00001 centers on a clip applier that uses first/second jaw longitudinal channels holding first/second stabilizing members. The proximal portions of the stabilizing members engage a proximal portion of the surgical clip to reduce movement, then compress and/or pivot proximally as the jaw members close, with separated proximal portions in the open configuration and contact between the proximal portions in the closed configuration.
Stated Advantages
Reduces movement of the surgical clip.
Supports controlling clip closure by providing contact between proximal end portions in the closed configuration.
Documented Applications
Applying a surgical clip to tissue using endoscopic/open ligation, with improved clip stability during endoscopic/open ligation.
