Abstract

The invention discloses a traction type annular cutting anastomat, and relates to the technical field of medical treatment. The anastomat comprises a clock seat and a movable tube, wherein the right side of the clock seat is provided with a cannula; the movable tube is installed on the right side of the cannula; the lower part of a movable wheel is connected with a handle; the upper part of a first pin shaft is connected with a connecting rod; a sliding groove is formed in the upper part of a second pin shaft; a locking ring is arranged on the outer wall of the movable tube; a movable pin is arranged on the right side of a through hole; a pull rod is arranged on the right side of a rotary knob; a screw tube is arranged in the clock seat; clamping blocks are arranged on the left side and the right side of the cannula; and a spring is connected to the left side of the movable pin. According to the invention, by arranging the screw tube and a screw rod, the clock seat and the pull rod canbe disassembled; by arranging a sheath, the clamping blocks and a groove, the antiskid effect is achieved and eccentricity is not caused; and meanwhile, by arranging the movable pin, the spring and the through hole, the self-locking function is achieved, so that the safety is greatly improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a pull-type circular cutting stapler. Background technique [0002] Stapler is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of manufacturing technology, the clinically used stapler is reliable in quality, easy to use, tight and suitable for tightness, especially its fast suturing and easy operation. And there are few side effects and surgical complications, etc., but some parts are more specialized and need to use a ring-shaped stapler to work. [0003] Existing pull-type circular cutting staplers exist during work and use. Most of the device’s clock base and pull rod are fixed integrated structures, which is inconvenient to disassemble and disinfect, and the device does not have a good anti-slip function, which is inconvenient to use. At the same time, the safety of the device is not good, and...
