Embodiment 1

[0078] figure 2 and image 3 Shown is an anorectal stapler for resecting hemorrhoidal tissue in the anorectum of a patient. Similar to some traditional anorectal staplers, this anorectal stapler also has a head that partially or completely extends into the patient's anorectum during use. The head has a length extending in the first direction d1, or in other words, the head protrudes forward from the stapler body along the first direction d1. The head is provided with: a clamping assembly for clamping the hemorrhoid tissue in the second direction d2 during use, an anastomotic staple 1 that moves in the third direction d3 to staple the hemorrhoid tissue, and moves in the fourth direction d4 to remove the hemorrhoid tissue Cutter 2. When in use, the head of the stapler extends into the patient's anorectum roughly along the aforementioned first direction d1, combined with external operations, the hemorrhoid tissue is processed through the aforementioned related components arra...

Embodiment 2

[0132] It is not difficult to understand that for other types of staplers that perform other surgical operations, such as digestive tract staplers and nasal cavity staplers, as long as this stapler needs to process the lesion tissue multiple times in sequence, for example, the stapler first treats the lesion The tissue is subjected to the first treatment (such as the treatment of clamping and fixing the lesion component in Example 1), and then the second treatment is performed on the lesion tissue (such as the treatment of stapling and cutting the lesion component in Example 1), and the anastomosis If the internal space occupied by relevant components changes before and after the first treatment of the lesion tissue by the stapler, the structure of the stapler can be designed using a concept similar to that of Embodiment 1. For example, the stapler is designed as Figure 24 , Figure 25 and Figure 26 shown in the structure, Figure 24-Figure 26 The structure of the stapler...

Abstract

The invention relates to an anorectal stapler for hemorrhoidectomy. The anorectal stapler is provided with a head portion extending forwards in the first direction, wherein the head portion is provided with a clamping assembly clamping haemorrhoids tissue in the second direction, an anastomosis nail moving in the third direction to nail the haemorrhoids tissue and a cutter moving in the fourth direction to cut off the haemorrhoids tissue. The fourth direction is roughly perpendicular to the first direction, and the cutter comprises a first cutter section roughly extending in the first direction and a second cutter section extending out of the front end of the first cutter section in a bent mode. By means of the anorectal stapler, the haemorrhoids tissue can be conveniently cut in a segmented mode, and the pain of a patient cannot be greatly increased.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to an anorectal stapler for hemorrhoidectomy. Background technique [0002] Hemorrhoids (hemorrhoids) are the most common anal disease. like figure 1 As shown, the hemorrhoid tissue 100 is generally elongated at the anorectum 200 of the patient, and its length extends approximately along the length direction of the anorectum. The length of the hemorrhoid tissue 100 is usually several times the width. [0003] The anorectal stapler is a medical device used to remove hemorrhoids, and it has a head that needs to be inserted into the anorectum of the patient in order to perform relevant treatment on the surgical site. The head of the stapler has a length extending in a first direction, and in use, the head extends (partially or fully) into the patient's anorum substantially along the aforementioned first direction. [0004] In order to achieve the above-mentioned "related tre...
