Embodiment Construction

[0013] When in use, put the stapler head plate (1) into the position of 2-4 cm on the hemorrhoidal mucosa under the adapted anoscope according to the pathological conditions, and use a negative pressure device (electric or manual suction device) to connect the negative pressure of the stapler head plate and rod The outer outlet (13); when the quantitative negative pressure draws the mucosal tissue on the hemorrhoid into the gap between the stapler head plate (1) and the stapler needle (4) ring knife (5) (the size can be set in advance according to the condition) ; Tighten the adjusting nut (12) to make the stapler (4) ring knife (5) close to the stapler head plate (1). The handle (12) is activated by hand, so that the connecting slide bar (7) and the connecting pad (6) are pushed forward so that the anastomotic needle (4) and the circular knife (5) complete the cutting and stapling tasks synchronously. After the treatment is completed, the negative pressure is subtracted, and ...

Abstract

The invention relates to an anastomat for mucous membranes on haemorrhoids, and the anastomat can treat the haemorrhoids and rectum mucous membrane prolapsed. The anastomat is formed by combining an anastomat head plate, a hollow connecting rod (with negative pressure holes), a girdling knife, a nailing needle, an anastomat body, an adjusting nut and a hand shank, and mucous membranes tissues on the haemorrhoids are sucked among the anastomat head plate, the girdling knife and the nailing needle by the utilization of negative pressure to replace an existing method of manual purse-string suture. The distance among the anastomat head plate, the girdling knife and the nailing needle is reduced through the adjusting nut, and then a nailing and girdling synchronous operation is performed.

Description

Technical field [0001] The utility model relates to a hemorrhoidal mucous membrane stapler for negative pressure suction for treating hemorrhoids and rectal mucous membrane prolapse in clinical medicine. technical background [0002] In 1975, Thomson proposed the "anal cushion" theory, which promoted people's re-understanding of hemorrhoids, and also led to changes in the treatment of hemorrhoids. A consensus has been formed to protect the function of the anal cushion as much as possible. Among the many methods of treating hemorrhoids, PPH surgery is the most revolutionary. [0003] At present, there are defects in the widely used PPH stapler in clinical practice: 1. The anoroscope fixed during the operation needs to be sutured with needles and threads, which is traumatic to the human body; Time-consuming, different doctors operate differently during suturing, the error is larger, and the method cannot be standardized and unified. Contents of the invention [0004] Aimin...
