A medical wedge stapler

Abstract

The invention provides a medical wedge-shaped suturing device, which includes an upper clamping seat and a lower clamping seat. The upper clamping seat includes nail pressing blocks on the left and right sides, a first arc-shaped rubber block and a downward-pressing arc-shaped bar. The nail compartment There are suturing nails installed inside, and the nail anvil is movably inserted in the nail cabin, and the lower clamping seat includes the nail forming blocks on the left and right sides, the second arc-shaped rubber block and the fixed arc-shaped bar, and the trigger lever The movable arm far away from the end of the vertical plate is fixedly connected with the hinge seat installed on the downward pressing arc bar. The upper clip seat and the lower clip seat of the present invention can be adjusted at a certain angle, which ensures that the tumor can be removed to the maximum extent when the tumor is completely resected. Reduce the damage to the normal tissue of the lung, and at the same time, after the incision is sutured, the tumor is resected by the expansion and contraction of the blade, which ensures the sequence of suture and cutting. pain and risk.

Description

technical field [0001] The invention relates to the technical field of medical staplers, in particular to a medical wedge stapler. Background technique [0002] Existing cutting and staplers are not suitable for all surgical operations. For example, when performing tumor resection at the edge of the lung, two large straight forceps are usually used to clamp the lung lesions on the edge in a wedge shape. The tips of the two forceps are close together, and the vascular forceps 1 to 2 cm from the lesion, the wedge-shaped lung tissue is excised with a razor blade and sent for examination, and then multiple parallel mattress sutures are made with thin silk threads. Wedge-shaped incision, but the above-mentioned cutting and suture methods are cumbersome and increase the risk of surgery; [0003] A wedge-shaped stapler with an application number of "CN200910259071.2" in the prior art includes upper and lower clamping bases, and a nail anvil is fixed on the upper clamping base, and...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned wedge-shaped suturing device overcomes the above problems, there are still relatively obvious defects in the use process: 1. Although the above-mentioned device can quickly complete wedge-shaped cutting and suturing, the cutting angle of the above-mentioned device cannot be changed. The principle is to preserve as much normal lung tissue as possible while ensuring complete resection of the tumor. Due to the limitation of the size of the tumor and the distance from the edge of the lung, the above-mentioned device can only complete wedge-shaped cutting at a fixed angle, and there is a large cutting limitation; 2. The above-mentioned device is equipped with a wedge-shaped cutter on the surface of the lower clamping seat to complete the cutting of the tumor tissue during the pressing process, but the above-mentioned device cannot guarantee the order of cutting and suturing. If the cutting is performed first, the cutting surface may be displaced. Suturing in this state may lead to the formation of fistula, and the safety of suturing cannot be guaranteed
