Example Embodiment

[0034] The invention will be further described in detail below with reference to the accompanying drawings.

[0035] The present invention provides a wire drive electric wound stapler, such as figure 1 As shown, including the outer casing 1, the servo motor 2, the roller shaft 3, the bearing housing 4, the anastomosis module 5, anastomotive wire 6, the guide rod 7, and the ribbon wheel 8.

[0036] The front end of the outer casing 1 has a tapered structural end cover 101, and an end cover 101 is opened. The guide rod 7 is inserted into the central hole fixed to the end cap 101, and the front end is fixedly mounted with anastomotic module 5. The guide rod 7 is a hollow lever, and the interior is used as a passage connected to the anastomosis module 5.

[0037] The servo motor 2 is mounted inside the outer casing 1, and the body end is fixed to the bottom surface of the outer casing 1, and the output shaft axis is designed perpendicular to the guide bar 7 axis. The servo motor 2 out...

Abstract

The invention discloses a wire-driven electric wound anastomat. The wire-driven electric wound anastomat is characterized in that the traction of a transmission wire is realized under the control of a motor, a nail pushing plate in an anastomosis module is further driven by the transmission wire to move forwards, and nails are pushed by the nail pushing plate. In the nail pushing process, the nail pushing plate is designed to be matched with an anastomosis baffle, the anastomosis baffle limits forward movement of anastomosis nails, the nail pushing plate is continuously controlled to move forwards, force is applied to the two sides of the anastomosis nails through the two ends of the front side of the nail pushing plate, and nail feet on the two sides of the anastomosis nails deform to achieve wound gathering. A nail storage bin is further designed in the anastomosis module, the anastomosis nails are placed in the nail storage bin, and when no anastomosis nail exists at a nail outlet, automatic nail feeding is achieved. The wire-driven electric wound anastomat can adapt to a surgical scene of a medical robot, and the safety distance between the robot and a patient is increased.

Description

technical field [0001] The invention belongs to medical robot equipment, and designs a wound stapler, specifically a wire-driven electric wound stapler. Background technique [0002] The principle of the stapler is similar to that of a stapler. The working principle is to fire staples into the human tissue, and the staples penetrate both sides of the tissue wound and seal it to achieve wound recovery. [0003] Staplers are mainly divided into linear staplers, circular staplers, linear cutting staplers, skin staplers, etc., and special staplers are used in different surgical situations. At present, it is widely used in gastrointestinal surgery, liver surgery, urology, etc., and is often used in intestinal resection, gastrointestinal closure, anal surgery, etc. [0004] Staplers currently available on the market are capable of stapling wounds of different types. Specific function and method of use: Manually gather the surface of the wound, and closely fit the nail opening. B...
