Abstract

The invention discloses a linear cutting suturing device, which comprises an upper tong clamp and a lower tong clamp, wherein the upper tong clamp and the lower tong clamp can realize the mutual closing or opening, the remote end of the lower tong clamp is provided with a nail cabin, a cutter feeding groove is arranged on the nail cabin in the axial direction, the lower tong clamp is in a U shape, a nail pushing rod and a cutter pushing rod are glidingly arranged inside the lower tong clamp, the remote end of the cutter pushing rod is provided with a cutter, the near end of the nail cabin is provided with a safety mechanism, the safety mechanism comprises a first press block, a triggering mechanism and at least one elastic element, the first press block is arranged in the nail cabin, the bottom end of the cutter is provided with a first notch, and the first notch can realize the longitudinal movement in the nail cabin under the effect of the elastic element and the triggering mechanism, so the first press block and the first notch can be selectively clamped and connected or separated. The linear cutting suturing device has the major beneficial effects that the structure is simple, the processing is convenient, safety and reliability are realized, and good popularization values are realized.

Description

technical field [0001] The invention relates to a linear cutting and suturing device, which belongs to the technical field of medical instruments. Background technique [0002] Linear cutting staplers are widely used in surgical operations for wound suturing, internal tissue suturing and cutting. A typical linear cutting stapler, as disclosed in U.S. Patent No. 5,129,570, has two functions of suturing and cutting. At the same time, excess tissue is removed. This type of linear cutting stapler generally includes upper and lower jaws, and a closing handle for closing the upper and lower jaws. The firing piece and the cutter can be moved relative to the staple cartridge at the same time, and the push button for driving the movement of the firing piece and the cutter. Staples are arranged in the staple cartridge, the firing piece sequentially pushes the staple pusher and pushes the staples to the anvil, and the cutter cuts off the tissue between the staple cartridge and the an...
