Intra-cavity straight-line cutting anastomat

Abstract

The invention discloses an intra-cavity straight-line cutting anastomat which comprises an instrument body, an extension pipe and an execution component, wherein the extension pipe is arranged on the instrument body, and the execution component is arranged at the far end of the extension pipe. The execution component comprises a nail cabin and a nail anvil sleeve matched with the nail cabin, the nail anvil sleeve comprises a first nail anvil and a second nail anvil, the first nail anvil is provided with a first height, the second nail anvil is provided with a second height, the nail cabin is matched with the first nail anvil or the second nail anvil, and outer diameter of the execution component is invariant. According to the intra-cavity straight-line cutting anastomat, by the aid of nail cabins of uniform sizes, the height of the nail anvils is changed or fixing position of a nail cabin body in a nail cabin frame is changed, different sewing heights can be achieved when the outer diameter of the execution component is not changed, mold opening cost is reduced, development period is shortened, the intra-cavity straight-line cutting anastomat has different forming heights and can use puncture outfits of uniform sizes, the puncture outfits are conveniently replaced and used by medical staff, the wound size of a patient can be decreased, and operation risks are reduced.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to an intracavity linear cutting stapler. Background technique [0002] The medical endoluminal linear cutting stapler is a medical device that is often used in surgical operations on physiological tissues such as the intestinal tract. It is a medical device that replaces traditional manual suturing. Due to the development of modern technology and the improvement of manufacturing technology, At present, the clinically used medical staplers are reliable in quality, easy to use, tight, and suitable for tightness, especially their fast suturing, easy operation, and few side effects and surgical complications. Resection is favored and respected by clinical surgeons at home and abroad. The difference in the performance of this instrument plays a crucial role in the overall surgical effect. [0003] The nail magazine and the nail anvil of the medical stapler are connected to form a cl...

Problems solved by technology

However, due to the different thickness of physiological tissue in different patients and different parts, the staple size of the currently selected endoluminal linear cutting stapler is not suitable for the physiological tissue

[0005] Correspondingly, in the prior art, corresponding to the intracavity linear cutting stapler, a set of medical intracavity linear cutting staplers are usually configured corresponding to each forming height, and the intracavity linear cutting staplers with different forming heights differ in configuration There are different sizes of staple cartridges, and the staple cartridges with different sizes are usually distinguished by color; in order to complete the suturing of physiological tissues of different thicknesses; however, there is another problem in this kind of endoluminal linear cutting stapler, which is configured with different sizes of staple cartridges Finally, the outer diameters of the executive components at the distal end of the intracavity linear cutting stapler are different. Correspondingly, corresponding to each color of the staple cartridge, it needs to be matched with trocars with different opening apertures; thus, if during the operation, it is found that When the suture height of the current endoluminal linear cutting stapler does not meet the demand and the endoluminal linear cutting stapler needs to be replaced, the trocar needs to be replaced at the same time; it increases the difficulty of suturing and increases the risk factor
