The present disclosure provides a surgical staple cartridge and a surgical end effector assembly with bumps. The bumps are provided on the surgical staple cartridge and / or a staple anvil portion, the bumps are positioned and sized to limit rotation of the surgical staple cartridge and the staple anvil portion relative to each other in a closed configuration, and to define a gap between the surgical staple cartridge and the staple anvil, the gap limits a maximum pressure applied to tissue by the surgical staple cartridge and the staple anvil, and prevents the tissue from being excessively squeezed to flow to area with no staple line coverage or being unevenly squeezed within the area with staple line coverage and thus affecting a tissue sealing quality. The present disclosure also provides a surgical instrument comprising the surgical staple cartridge or the surgical end effector assembly.

A surgical instrument for treating a tubular organ includes a shaft assembly, a stapling assembly, a trocar, and one or more light sources. The stapling assembly is disposed at the distal end portion of the shaft assembly and includes a circumferential sidewall having a distal edge to define a stapling line. The trocar is operably movable relative to the stapling assembly along an axis of the stapling assembly between an extended position and a retracted position. The one or more light sources are used to emit light transmissible through the wall of the tubular organ. Thus, by detecting light transmitted through the wall of the tubular organ, a user of the surgical instrument can position the trocar, the distal edge of the stapling assembly, or both in the tubular organ.

This invention provides a surgical instrument for stapling and a method for using it. [Solution] The stapling surgical instrument includes a handle assembly, a shaft assembly, and a plurality of loading units having different staple line lengths. The handle assembly includes a control circuit having mounting sensing switches and a slider. The shaft assembly includes a sensing mechanism. Any loading unit is detachably mounted to the shaft assembly. The number of mounting sensing switches is less than the number of staple line lengths of the loading units. Mounting a loading unit drives the sensing mechanism to push the slider, which either activates any mounting sensing switch to generate a first signal or does not activate it to generate a second signal. The control circuit identifies whether a loading unit is unmounted or has a staple line length based on all combinations of all first or second signals.

Systems, devices and methods are provided for introducing and removing collapsible anvils to and from a target site in a patient, such as a proximal bowel during a colon resection procedure. A circular stapler instrument comprises a staple assembly comprising a plurality of staples and a cutting element and an anvil movably coupled to the stapling assembly. The anvil comprises a head and a shaft. The head comprises a tissue contacting surface defining staple forming pockets.

The present invention relates to a prostate stapler device, comprising an implantation mechanism and an operating mechanism. The implantation mechanism includes a puncture needle assembly and a staple line assembly. The operating mechanism includes: a first drive assembly, which includes a first motor, a first gear and a first rack that mesh with each other; an actuator assembly, which includes a puncture needle actuator, a staple line actuator, and a first elastic member. When performing a puncture, the first rack provides a linear driving force to trigger the actuator assembly to move from an initial position along a first direction to a puncture completion position to perform the puncture. When retracting the puncture, the first rack drives the puncture needle actuator to move the puncture needle assembly along a second direction to complete the puncture. Then, the staple line actuator moves along the second direction under the elastic force of the first elastic member to tighten the staple line assembly to achieve retraction. The stapler device of the present invention is simpler to operate, can improve stapler efficiency, reduce vibration and noise generated during the puncture process, and has a long service life.

Multi-articulated cartridge for endoscopic surgical stapler (mechanically or electrically actuated) with integrated tissue cutting system using an electric field. It allows video or robotic surgery with the creation of stapling lines with a sharp curve (not possible with currently available devices) and automatic cauterisation of the transected tissue, preventing bleeding. Ideal for parenchyma-sparing lung surgeries and for patients at high risk of bleeding. The device features a completely new constructive concept inspired by nature, by means of observation of centipedes and millipedes. The device is very promising for use in uniportal surgeries and natural orifice surgery (NOTES).
