Structural features of stapler
The adjusting knob of the digestive tract stapler comprises a knob body, the knob body is rotatably connected with the stapler body, and the knob body is threaded with a screw; The knob body is provided with a radially enlarged radial convex part, and the radial convex part has at least two. The radial convex part makes the knob butterfly shaped. When using it, the finger can push the radial convex part to directly obtain the torque to make the knob rotate, which can easily compress the human tissue to the predetermined thickness. There is almost no friction between the finger and the radial convex part, which effectively prevents the damage of the latex gloves worn by the operator.
The stapling nail of the digestive tract stapler consists of a nail crown and a nail leg in a roughly U shape. The nail leg has a bending part, the upper part of the bending part is the upper part of the nail leg, the lower part of the bending part is the lower part of the nail leg, the lower part of the nail leg bends inward at the bending part relative to the upper part of the nail leg, and the length of the nail leg of the nail leg is 4.84mm -4.92mm. The height of the legs of the staples can be formed normally. After forming, the legs are bent at the bending part, which improves the probability of standard forming.
The linear cutting stapler comprises a handle body, a push knife, a nail bin seat and a nail butting seat. The handle body isprovided with a push button for controlling the push knife. The handle body is rotationally connected with a cam, and the cam is provided with a hook part. The side part of the cam is provided with a safety mechanism. When the safety mechanism is locked, the hook part is hooked on the push button, and the cam is fixed relative to the handle body; When the safety mechanism is in the unlocked state, the hook part releases the push button. When the safety mechanism is locked, the cam is fixed relative to the handle body, and the push button cannot move forward, so that the push knife can not be pushed too early when the position of the instrument is not adjusted properly.
The circular cutting stapler comprises a nail seat sleeve and a nail butting seat, wherein a sliding rod sleeve is arranged in the nail seat sleeve, the nail butting seat is connected with a sliding rod, and the sliding rod is inserted in the sliding rod sleeve. The sliding rod is provided with a first rotation stopping plane, the inner wall of the sliding rod sleeve is provided with a second rotation stopping plane, and the two rotation stopping planes are fitted. One part of the sliding rod and the sliding rod sleeve is provided with a guide rib along the axial direction of the sliding rod, and the other part is provided with a guide groove along the axial direction of the sliding rod, and the guide rib is inserted in the guide groove. Through the coordination of the guide rib and the guide groove, the positioning between the sliding rod and the nail seat sleeve is accurate, that is, the positioning between the nail seat sleeve and the nail seat is accurate, so as to ensure the correct forming of the sewing nail.
