Disclosed is an electrosurgical instrument including an end effector with a cartridge having an asymmetric cartridge body.

A surgical instrument assembly is disclosed. The surgical instrument assembly comprises a shaft, an articulation region, and an end effector attached to the shaft by way of the articulation region, wherein the end effector is configured to be articulated relative to the shaft. The shaft comprises an outer housing, an inner spine positioned with the outer housing, and a core member positioned within the inner spine. The core member comprises a distal end attached to a component the end effector and a proximal end attached to the proximal housing, wherein the core member comprises a material different than a material of the inner spine, and wherein the core member defines a maximum system stretch of the inner spine.

A surgical instrument comprising a translatable closing bar and a translatable firing bar is disclosed.

A staple cartridge comprising a cartridge body including staple formation features is disclosed.

An integrated ablation needle (100), comprising a cannula (10) and an electrode needle (20) that is movably and penetratingly installed within the cannula (10); the electrode needle (20) comprises a needle tip (21) located at the far end and a needle rod (23) connected to the near end of the needle tip (21); at least a portion that is near to the needle tip (21) of the needle rod (23) is provided with a sampling groove (231); and the far end of the cannula (10) is provided with a cutting edge (11). The cannula (10) moves along the axial direction relative to the needle rod (23) so as to expose or cover the sampling groove; when the sampling groove (231) is exposed, a tissue portion around the needle rod (23) enters the sampling groove (231); and when the sampling groove (231) is covered, the cutting edge (11) cuts off tissue inside and outside of the sampling groove (231), such that the tissue within the sampling groove (231) is acquired as a biopsy sample. Further provided is an ablation system (1000) comprising an integrated ablation needle (100). The integrated ablation needle (100) and the ablation system (1000) integrate ablation and biopsy functions on the same ablation needle (100), without needing to independently execute a biopsy step, thus avoiding repeated puncturing, reducing damage to the human body, and reducing operation time.

The present invention is directed to a multi-probe ablation simulation and guidance system and method for use in tissue ablation procedures. In use, the relative locations of a plurality of ablation probes capable of providing ablation energy are determined, and the effect of energy provided by the probes based on the determined locations is predicted to identify a simulated ablation volume. This simulated ablation volume is compared with a target tissue volume. The relative locations of the probes can be adjusted based on the comparison between the simulated ablation volume and the target tissue volume, and the predicted effect rerun until the simulated ablation volume encompasses the target tissue volume to be ablated and necrotized.

The present invention relates to comprehensive systems, devices and methods for delivering energy to tissue for a wide variety of applications, including medical procedures (e.g., tissue ablation, resection, cautery, vascular thrombosis, treatment of cardiac arrhythmias and dysrhythmias, electrosurgery, tissue harvest, etc.). In certain embodiments, systems, devices, and methods are provided for treating a tissue region (e.g., a tumor) through application of energy.

A system for recording or recalling ablation information includes a workstation, and control circuitry. The workstation may include a display, a user input device, and a memory. The workstation may be configured to be in electrical communication with an ablation device. The control circuitry may be in electrical communication with the ablation device and the memory. The control circuitry may be configured to receive input associated with an ablation procedure performed by the ablation device, and associate the input with an anatomical structure of the patient.

Systems, devices, and methods for providing an endoluminal transhepatic access to a patient pancreaticobiliary system in an endoscopic procedure are disclosed. An example of a transhepatic access procedure comprises navigating a steerable elongate instrument through a body cavity or channel and exiting to a access site of liver, puncturing the liver from the access site, extending the steerable elongate instrument through the liver and into the pancreaticobiliary system and performing an operation therein. Following the operation, the steerable elongate instrument can be retreated, and the access site of liver can be closed with a closure means. Apparatus and methods of training a machine-learning model and using said model to identify patient candidacy for retrograde access based on images of patient anatomy are also disclosed.

A system to treat a patient comprises a user interface that allows a physician to view an image of tissue to be treated in order to develop a treatment plan to resect tissue with a predefined removal profile. The image may comprise a plurality of images, and the planned treatment is shown on the images. The treatment probe may comprise an anchor, and the image shown on the screen may have a reference image marker shown on the screen corresponding to the anchor. The planned tissue removal profile can be displayed and scaled to the image of the target tissue of an organ such as the prostate, and the physician can adjust the treatment profile based on the scaled images to provide a treatment profile in three dimensions. The images shown on the display may comprise segmented images of the patient with treatment plan overlaid on the images.
