Patent number: 11944503Abstract: A surgical instrument including a system for stopping a beam of the surgical instrument from impacting a distal pin when reversing a knife is disclosed. A knife assembly of the surgical instrument comprises the knife, the beam, and a firing nut. A firing lead screw can drive the firing nut distally and proximally. A firing screw compression spring extends along the firing lead screw and applies a load proximally on the firing nut when the firing nut is driven toward a distal end of the firing lead screw.Type: GrantFiled: December 21, 2022Date of Patent: April 2, 2024Assignee: Standard Bariatrics, Inc.Inventors: Adam R.

Patent number: 11931210Abstract: A system for preventing unwanted tissue migration in surgical staplers includes a surgical stapler having an end effector including an upper jaw and a lower jaw. A distal end of the upper jaw is connected to a distal end of the lower jaw, and a proximal end of the upper jaw is connected to a proximal end of the lower jaw. First and second tissue stops are formed on the distal and proximal ends of the lower jaw, respectively.
