Patent number: 12137903Abstract: Locking assemblies for surgical clamping and cutting instruments include a locking member and a switch. A drive member may be configured to releasably engage a knife and/or a shuttle of the surgical instrument for translating the knife and/or shuttle in a distal direction through a firing stroke. The locking member is movable from a first position permitting distal translation of the drive member through the firing stroke, and a second position inhibiting distal translation of the drive member through the firing stroke. A switch, when proximally positioned, releasably engages the locking member to maintain the locking member in the first position. The switch disengages from the locking member when the switch is moved to a distal position.Type: GrantFiled: August 18, 2022Date of Patent: November 12, 2024Assignee: Intuitive Surgical Operations, Inc.Inventors: Atal C Patel, Matthew Aaron Wixey

Patent number: 12137907Abstract: 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: GrantFiled: October 25, 2023Date of Patent: November 12, 2024Assignee: Applied Medical Resources CorporationInventors: Atal C.

Publication number: 20240285277Abstract: 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: ApplicationFiled: May 9, 2024Publication date: August 29, 2024Inventors: Matthew M. Becerra, Steven E. Decker, Timothy M. Hopkins, Atal C. Patel, Babak D. Jasemian

Patent number: 11986184Abstract: Surgical clamping and cutting instruments are disclosed. In one aspect, a surgical instrument comprises an elongate shaft with an end effector having first and second jaws, a release member movably coupled to the end effector and a drive member configured to translate relative to the end effector. The instrument further includes a locking member movable from a first position permitting distal translation of the drive member, to a second position preventing distal translation of the drive member. The locking member moves into the second position after the drive member has been driven distally. This inhibits or prevents hazardous actuation of a knife or drive beam when, for example, there is a spent or previously fired cartridge in place.Type: GrantFiled: October 26, 2022Date of Patent: May 21, 2024Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Atal C.

Publication number: 20230338025Abstract: A surgical stapling system can include a reload shaft. The shaft can include an elongate tubular member with have a jaw assembly at the distal end thereof and a coupling collar at the proximal end thereof. The shaft assembly also includes an articulation joint coupling the jaw assembly to the distal end. A drive member and an articulation member extend within the tubular body of the shaft from the proximal end to the distal end. A firing member is connected to the distal end of the drive member such that advancement of the drive beam advances the firing member to close the jaw assemblies and fire staples from a reload positioned in the jaw assembly. The shaft assembly can also include a lockout mechanism to prevent a firing operation on a previously-fired reload or no reload.Type: ApplicationFiled: June 16, 2023Publication date: October 26, 2023Inventors: Babak Jasemian, Steve E.

Publication number: 20230263526Abstract: 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: April 25, 2023Publication date: August 24, 2023Inventors: Timothy M. Hopkins, Atal C. Patel, Donald L. Gadberry, Matthew M. Becerra
