An apparatus is provided for stapling tissue. The apparatus includes an anvil and a trocar selectively coupled with the anvil. The anvil may have an inner opening and a plurality of staple pockets aligned around a surface of the anvil. The anvil may be inserted trans-orally through an esophagus prior to being coupled with the trocar. The trocar may include a shaft and a locking assembly. The locking assembly may secure the anvil in position relative to the trocar when the locking assembly is in the expanded position. The apparatus may also include an alignment assembly to align the staple pockets of the anvil relative to the apparatus. The apparatus may also include an introduction assembly to guide the anvil through the esophagus.

Various surgical systems are disclosed. A surgical system can include a surgical robot and a surgical hub. The surgical robot can include a control unit in signal communication with a control console and a robotic tool. The surgical hub can include a display. The surgical hub can be in signal communication with the control unit. A facility can include a plurality of surgical hubs that communicate data from the surgical robots to a primary server. To alleviate bandwidth competition among the surgical hubs, the surgical hubs can include prioritization protocols for collecting, storing, and/or communicating data to the primary server.

An apparatus and method is provided for accessing an abdominal cavity of a patient via the anus for any number of surgical operations, e.g., colon cancer, appendectomy, lymph node biopsy, etc. The apparatus includes a tubular body that extends to an open end having a plurality of holes. The tubular body is inserted into the intestine of the patient, and a clamp is inserted through the tubular body of the apparatus and into the intestine. The clamp and the attached intestine is then pulled into the tubular body, so that the intestine can then be cut. The clamp and the adjacent intestine are then moved out of the tubular body so that the surgery may be performed through the intestine. The cut ends of the intestine can then be reattached (e.g., stapled, sutured, etc.) following completion of the surgery.

A device for use in bariatric surgery includes a flexible hollow tube extending from a proximal end to a distal end and defines a channel therebetween. A series of openings is defined in a distal portion of the tube allowing for fixation of tissue using suction. A flexible member has an initial position disposed alongside the tube and is deployable to a subsequent position in which the flexible member engages a greater curvature of a stomach. The flexible member is configured to be deployable to automatically assume a shape of a greater curvature of a stomach. The flexible member includes a bulging region and a tapering region when deployed. The flexible member is releasably attached to the distal end of the tube.

A double-balloon catheter device for gastrointestinal anastomosis. The double-balloon catheter device for gastrointestinal anastomosis includes a liquid injection assembly, a double-balloon assembly, and a supporting device (15) connecting the liquid injection assembly and the double-balloon assembly. The liquid injection assembly includes a first balloon liquid injection connection port (2), a guide wire connection port (3), and a second balloon liquid injection connection port (4). The double-balloon assembly includes a double-balloon catheter device (5), and includes a first balloon (6) and a second balloon (7) that can expand-and that are respectively disposed on the two ends of the double-balloon catheter device (5). The double-balloon catheter device (5) is provided with a first balloon liquid injection channel (51), a guide wire channel (52), and a second balloon liquid injection channel (53).

A wound protector includes a tubular body that is configured to protect a cut site of an anastomosis. The wound protector can be secured to the anastomotic site after formation of the anastomosis or, alternatively, secured to the anastomotic site during formation of the anastomosis. The tubular body of the wound protector is positioned and configured to shield the anastomosis from waste material passing through a digestive tract of a patient.

A system for controlling a robotic end-effector is disclosed. The system includes a robotic arm, a surgical tool including an end-effector with articulatable arm and a clamp jaw. A tool driver is coupled to the surgical tool and a motor is coupled to the tool driver and is configured to drive the surgical tool. A sensor is configured to sense external forces applied to the end-effector. A central control circuit is configured to control the tool driver. The central control circuit is configured to receive a sensed parameter from the sensor, receive a sensed motor current (I) from the motor, and control the tool driver based on the sensed parameter and the motor current (I).

A circular stapler apparatus for stapling tissue has a circular stapling head operable to drive staples toward an anvil to form the staples in a circular array. The anvil includes an anvil head, a proximal shaft extending proximally from the anvil head and having a proximal end disposed in a first plane, and a first pivot connecting the anvil head to the proximal shaft. The first pivot is operable to be disposed in a second plane that is laterally offset from the first plane. The anvil is configured to rotate via movement through multiple pivot points. The anvil may be configured to rotate to a position in which a portion of the anvil head is disposed below the first pivot and between the first pivot and the proximal shaft such that the anvil head is acutely angled with respect to a longitudinal axis of the proximal shaft.

A mesh element having a mesh gauge selected to control flow of materials therethrough. The mesh element is implantable into an anatomical structure upstream of a body passage or within a body passage to control flow of materials through the body passage. The mesh element may be coupled to a support structure to facilitate anchoring of the mesh element in place relative to the body passage. The support structure may have a lumen defined therethrough to allow flow of materials through the body passage, with the mesh element regulating the flow of materials into the lumen. The mesh element alternatively may be directly coupled to an anatomical structure upstream of a body passage to regulate or determine flow of materials through the body passage.

An apparatus for delivery of a device into a hollow organ and a method of delivery are provided. The apparatus includes an elongated tube having proximal and distal openings and being configured for carrying the device on a distal portion thereof. The apparatus further includes a tubular cover for covering at least a portion of the device when mounted on the elongated tube, the tubular cover being radially elastic and axially non-elastic. The tubular cover is retrievable into the elongated tube through the distal opening, such that when the device is mounted on the elongated tube and covered by the tubular cover, retrieval of the tubular cover into the elongated tube uncovers the device for delivery into the hollow organ.
