Description
Technical Field
The invention relates to an empty nail bin safety device of a disposable arc-shaped cutting anastomat, which is matched with the disposable arc-shaped cutting anastomat for use, and is particularly suitable for anorectal hemorrhoid cutting operation and rectal polypectomy.
Background
Anal fistula is commonly known as hemorrhoids, which are common diseases and frequently occurring diseases of human beings. According to the general investigation data, the incidence rate of anorectal diseases is 59.1%, hemorrhoids account for 87.25% of all anorectal diseases, and internal hemorrhoids account for 52.19% of all anorectal diseases most frequently. The male and female can get ill, the incidence rate of female is 67%, the incidence rate of male is 53.9%, and the male can get ill at any age, and the male is gradually aggravated with the increase of age, so that the theory of 'ten people and nine hemorrhoids' is provided.
Cutting staplers are devices used medically to replace traditional manual cutting sutures. The arc-shaped cutting anastomat has various use advantages as a disposable cutting anastomat, for example, the arc-shaped design at the front end of the arc-shaped cutting anastomat is convenient to penetrate into a narrow space in the deep part of anorectal, the cutting and the sewing are finished synchronously, and the operation steps are simplified. When the arc-shaped cutting anastomat is used, a sectional closing mode is adopted, so that the tissue can be conveniently adjusted and positioned, the positioning needle is used for positioning and locking, and then cutting and suturing are carried out. The traditional arc cutting anastomat adopts the positioning button to push back and forth to control the positioning needle, so that unstable factors exist in control, human tissues are easy to displace, the continuous repositioning is required, the operation time is prolonged, the inaccurate cutting and suturing positions are seriously caused, and more serious consequences are generated. In addition, the traditional arc-shaped cutting anastomat can not be used for replacing components, multiple instruments can be used in the same operation, so that the operation cost is high, and a larger economic burden is brought to a patient.
At present, an arc-shaped cutting anastomat is free of an empty staple cartridge safety device, a certain risk exists in an operation, and after a doctor finishes firing, if the already fired assembly is used again to cut anastomosis, the risk of only cutting and not suturing is caused, so that an operation accident is caused.
