Patent number: 10792038Abstract: A surgical stapler is provided that includes a spring loaded lift that automatically adjusts a staple cartridge and/or staple formation between a range of sizes. The lift is automatically released as the staple firing mechanism begins its forward translation of the firing sequence. The automatic one-way adjustment also adjusts the staple cartridge while maintaining the cartridge parallel to the anvil to provide consistent staple formations.Type: GrantFiled: September 13, 2016Date of Patent: October 6, 2020Assignee: Applied Medical Resources CorporationInventors: Matthew M. Becerra, Steven E. Decker, Timothy M. Hopkins, Atal C. Patel, Babak D. Jasemian

Publication number: 20200214704Abstract: A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler. The powered handle can include a manual return mechanism.Type: ApplicationFiled: March 17, 2020Publication date: July 9, 2020Inventors: Christina N. Reed, Matthew M. Becerra, Andrew J.

Publication number: 20200178961Abstract: A handle assembly for a surgical stapler can comprise a rotatable actuation shaft. The actuation shaft can have a first rotational orientation in which it can actuate a jaw assembly in a repeatable open and close mode, a second rotational orientation in which it can actuate a jaw assembly in a staple firing mode, and a third rotational orientation in which it can actuate a jaw assembly in a reversing mode. The handle assembly can include a rotational mechanism arranged to discretely position the rotatable actuation shaft in one of the rotational orientations. The rotational mechanism can be arranged for single handed operation such as by including a slidable switch or selector to rotate the actuation shaft.Type: ApplicationFiled: February 12, 2020Publication date: June 11, 2020Inventors: Atal C.

Publication number: 20190175177Abstract: A surgical stapler is provided. The stapler employs circumferential channels through which staples are deployed along an arc pathway against an anvil surface. The curved channels allow staples with relatively longer legs to be used in the stapler having a smaller diameter at the jaws. Also, by utilizing a curved path, a much larger staple can be placed in the same diameter device. Specialized curved staples for use with the stapler of the present invention are also provided. To further enable the benefits of the stapler with circumferential channels and method of staple deployment, novel jaw reinforcement structures are provided in the present invention. The jaw reinforcement structures are located towards the center or bladeline of the device instead of around the circumference as in conventional staplers, thereby clearing the outer area near the circumference of the device to provide room for longer staples and staple firing components.Type: ApplicationFiled: February 14, 2019Publication date: June 13, 2019Inventors: Timothy M. Hopkins, Atal C. Patel, Donald L. Gadberry, Matthew M. Becerra

Patent number: 9955992Abstract: The invention relates to a tissue morcellator for minimally invasive surgery. The morcellator has a metallic cutting ring mounted on a visually transparent hollow cylinder, which in combination with a visually transparent outer morcellator tube enables a surgeon to visualize the inside of the morcellator shaft for detection of loose tissue fragments in the device. A tenaculum used with the morcellation device has a spacer for preventing contact with the blade. The cutting tube can oscillate, rather than rotate, along the longitudinal axis of the cutting tube. The morcellator utilizes an extendable tissue guide on the outer tube of the morcellator shaft for preventing the tissue from rotating along the longitudinal axis of the morcellator tube. This allows the tissue to be continuously rotated into the morcellator device for continuous peel. The tissue guide can also be fully retracted to allow for coring of the bulk tissue.Type: GrantFiled: October 24, 2012Date of Patent: May 1, 2018Assignee: Applied Medical Resources CorporationInventors: Boun Pravong, Kennii Pravongviengkham, Matthew M.

Publication number: 20180103951Abstract: A surgical stapler includes a jaw assembly at a distal end connected to a handle assembly that is configured to control the stapler and actuate the deployment of staples. The surgical stapler successfully eliminates intermediate caming portions commonly known as pushers that are located between the staples and a translating slider. The staples are located in pockets at an angle such that the base of the staple is parallel to an angled caming surface of the slider. The translating slider comes into direct contact with staples during deployment as the slider moves through each staple pocket where staples are partially supported by recesses along the slider pathway. The staples are deployed at an angle against the anvil surface. Because there are no pushers, a great deal of space is saved resulting in a much smaller diameter surgical stapler that is particularly suitable for laparoscopic stapling applications.Type: ApplicationFiled: December 19, 2017Publication date: April 19, 2018Inventors: Timothy M. Hopkins, Donald L. Gadberry, Matthew M. Becerra, Babak Jasemian, Gary M. Johnson, Steven E. Decker

Publication number: 20180036005Abstract: Jaw assemblies for a surgical stapler are provided. The jaw assemblies comprise a first jaw having a first clamping surface and a plurality of staples disposed therein and second jaw assembly having a second clamping surface. The jaw assemblies can be actuated from a closed configuration in which the first clamping surface contacts or is adjacent to the second clamping surface to an open configuration in which the second jaw is pivoted away from the first jaw to a stapling position in which the second clamping surface is parallel to the first clamping surface and spaced apart from the first clamping surface. A pivoting link or sliding pivot joint can couple the second jaw to the first jaw to facilitate motion between the closed position, the open position, and the stapling position.Type: ApplicationFiled: October 19, 2017Publication date: February 8, 2018Inventors: Jonathan Covach, Matthew M. Becerra, Gary M. Johnson
