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 patient's stomach may be secured to the patient's diaphragm. A method to accomplish this includes visualizing a wall of a patient's stomach adjacent the patient's diaphragm from within the patient's stomach, inserting a fastener deployment apparatus down the patient's esophagus and into the mammalian's stomach, and fastening the patient's stomach to the patient's diaphragm with the fastener deployment apparatus and from within the stomach. The procedure may be employed to advantage to treat a hiatal hernia, for example, either alone or in conjunction with the restoration of the patient's gastroesophageal flap valve.

A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor, a control circuit, and a position sensor. The displacement member is configured to translate. The motor is coupled to the displacement member to translate the displacement member. The control circuit is coupled to the motor. A position sensor is coupled to the control circuit. The position sensor is configured to measure the position of the displacement member and to measure an articulation angle of an end effector relative to a longitudinally extending shaft. The control circuit is configured to determine the articulation angle between the end effector and the longitudinally extending shaft and set motor velocity based on the articulation angle.

A system and a method are disclosed for forming an anastomosis between a first layer of tissue and a second layer of tissue of a patient's body. The system includes a first anastomosis device component and a second anastomosis device component configured to interact with the first anastomosis device component. The first anastomosis device component is configured to be delivered to a first lumen inside the patient's body. The second anastomosis device component is configured to be delivered to a second lumen inside the patient's body. The second anastomosis device includes one or more sensors configured to capture sensor data for determining an alignment of the second anastomosis device component relative to the first anastomosis device component, or for characterizing the position or orientation of the second anastomosis device component in three-dimensional space.

A method is provided for operating a powered surgical stapler having a motor unit, a controller, and a stapling assembly having a plurality of movable members that are actuatable longitudinally by the motor unit to clamp, staple, and cut tissue. The controller determines that a movable member of the stapling assembly is in a first predetermined position, and then executes an actuation algorithm to activate the motor unit to actuate the movable member longitudinally from the first predetermined position toward a second predetermined position. The controller observes an actual longitudinal displacement of the movable member between the first and second predetermined positions. The controller compares the actual longitudinal displacement to an expected longitudinal displacement and determines that the actual longitudinal displacement differs from the expected longitudinal displacement by a difference value. The controller then adjusts the actuation algorithm based on the difference value.

A handle assembly and a stapler including the same are provided. The handle assembly includes a first handle and a second handle having an un-linked state and a linked state. When the first handle and the second handle are in the un-linked state, and the first handle is rotated in a first direction, the second handle is not rotated, thereby to fire the stapler. When the first handle is in the linked state, and the first handle is rotated in the first direction, the second handle is actuated to rotate in the first direction to fire the stapler. During operation, no matter the stapler is ready to be fired or not, the first handle can be pressed to move by the doctor. However, when the stapler is not ready to be fired, the second handle is not actuated by the first handle, thereby will not fire the stapler.

A surgical suturing tracking system is disclosed. The surgical suturing tracking system is configured to detect and guide a suturing needle during a surgical suturing procedure. The surgical suturing track system comprises a control circuit configured to predict a path of a needle suturing stroke after receiving an input from a clinician, detect an embedded tissue structure, and assess proximity of the predicted path and the detected embedded tissue structure.

Systems and methods for forming an anastomosis between two adjacent walls of a digestive tract are provided. The system can include first and second magnetic implants configured to magnetically couple through two adjacent walls of the digestive tract to compress a portion of the two adjacent walls therebetween and form a necrotic area that becomes surrounded by a scarred edge following a healing time period. The magnetic implant can include a magnetic member and a non-magnetic member. The system can include a retention member extending outwardly from a corresponding one of the first and second magnetic implants, the retention member being configured to retain the magnetic implants in position and prevent passage thereof through the necrotic area during the healing time period, and to maintain an engagement between the magnetic member and the non-magnetic member during the healing time period and enable disengagement thereof following the healing time period.

A method for resetting a stapling apparatus includes providing an apparatus with a cam member in a fired position. A circuit of the apparatus is then changed from a first polarity state to a second polarity state. A motor of the apparatus is then activated to rotate the cam member from a fired position back to a home position while the circuit is in the second polarity state.
