A method for anastomosing an alimentary tract according to a first aspect of the invention includes a first step of inserting an endoscope into an alimentary tract through a natural opening in a state where a distal end part of a tube body is coupled to an outer periphery of a distal end part of the endoscope; a second step of making a hole in a tract wall of the alimentary tract; a third step of inserting the tube body through the hole; a fourth step of grasping the distal end part of the tube body disposed through the hole; a fifth step of separating the tube body from an outer periphery of the distal end part of the endoscope; and a sixth step of delivering the treatment part up to the hole after the fifth step.

A lever latching system comprising: a housing; a lever having a latch pin fixedly mounted to the lever, the lever being movably mounted to the housing so that the latch pin moves in an arc; and a latch plate movably mounted to the housing for linear movement with respect to the housing, the latch plate comprising a labyrinth for receiving the latch pin.

Disclosed is a reusable surgical instrument (1) with an articulated end-effector (3), such as a dissector, scissor or grasper, to enhance a surgeon's performance during various surgical procedures. The longitudinal axis of the instrument is defined by a shaft (2), comprising an internal structural element (2″) covered by an external tube (2′), which may be inserted through a surgical incision into the body of a patient, optionally through a trocar. The articulated end-effector (3) is mounted on the distal extremity of the shaft's internal structural element and comprises a plurality of links interconnected by a plurality of joints, whose movements are remotely actuated by the surgeon's hands. This remote actuation is accomplished via mechanical transmission (5, 6, 7), mainly composed of flexible elements, which are able to deliver motion from a set of actuation elements, placed at a proximal extremity of the shaft (2), to the instrument's articulated end-effector (3). The external tube (2′) can be easily and individually detached from the shaft (2) after each procedure, so that the instrument (1) can be more effectively cleaned and sterilized.

Provided is an endoscope system including an elongated tube with one or more channels extending in a longitudinal direction along the elongated tube. The channels allow inserting of a viewing device for obtaining images from the distal end, inserting of surgical instruments to operate at the distal end, or passing of materials such as air or water. The channel for inserting the viewing device is enclosed or has a cover at the distal end of the elongated tube, such that the viewing device has no direct contact of body tissues, thereby eliminating the need for sterilization. Also provided is a safe and economical method for conducting endoscopy involving one-time use of a tube to keep the viewing device from directly contacting the body tissues.

A method for adjusting the operation of a surgical suturing instrument using machine learning in a surgical suite is disclosed. The method comprises gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical suturing instrument comprising a suturing needle configured to be mechanically advanced through a suturing stroke, analyzing the gathered data to determine an appropriate operational adjustment of the surgical suturing instrument, and adjusting the operation of the surgical suturing instrument to improve the operation of the surgical suturing instrument.

Provided is a locking apparatus, and more particularly, to a locking apparatus with improved locking performance as a locking unit is stuck between different members capable of moving relative to each other and in which locking is released as an unlocking unit pushes the locking unit.

Three-arm clamp includes: clamping assembly and releasing member connected to each other, clamping assembly includes fixed arm, and two movable arms respectively rotatably connected to fixed arm by hinge pin; the proximal end of each movable arm is provided with first sliding slot, and sliding pin is slidably arranged in first sliding slot; the proximal end of fixed arm is provided with inner cavity, and releasing member is inserted into inner cavity and connected to sliding pin; the proximal end of each movable arm is provided with elastic sheet; movable arms and fixed arm are closed by clamping, and elastic sheets are folded in inner cavity, in radial direction of fixed arm, from connecting end to free end and abut against releasing member; and releasing member is separated from movable arms, and the free end of each elastic sheet elastically abuts against inner wall of inner cavity.
