Embodiment Construction

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

[0035] The invention provides a wire-driven electric wound stapler, such as figure 1 As shown, it includes a casing 1, a servo motor 2, a winding shaft 3, a bearing seat 4, an anastomosis module 5, an anastomosis transmission wire 6, a guide rod 7 and a winding wheel 8.

[0036] The front end of the housing 1 is equipped with a tapered structure end cover 101, and the end cover 101 has a central hole. The end of the guide rod 7 is plugged and fixed in the central hole of the end cover 101, and the anastomosis module 5 is fixedly installed at the front end. The above-mentioned guide rod 7 is a hollow rod, and the inside serves as a channel for connecting the anastomosis transmission wire 6 to the anastomosis module 5 .

[0037] The servo motor 2 is installed inside the casing 1, the body end is fixed on the bottom surface of the casing 1, and the axis of the...

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...
