Embodiment 1

[0023] Example 1 Anorectal PPH operation guide stapler

[0024] like Figures 1 to 3 As shown, the guide stapler for anorectal PPH operation in this embodiment includes an open ring 1 made of elastic material that can be inserted into the anal canal, and two ends of the opening of the open ring 1 are respectively provided with a The rod body 2a held by a person can adjust the diameter of the split ring 1 by adjusting the distance between the two rod bodies 2a. During the operation, after the anorectal dilator is inserted into the anal canal, the distance between the two rods can be adjusted to reduce the diameter of the split ring. Put it in the back of the anorectal dilator, release the two rods, and make the split ring in the crimped state rely on its own elasticity Expand and enlarge, so that the opening ring can contact the mucosal tissue in the anal canal, and pulling the rod outward can make part of the mucosal tissue be squeezed between the end face of the opening ring...

Embodiment 2

[0026] Example 2 Anorectal PPH operation guide stapler

[0027] like Figure 4 As shown, the guide stapler for anorectal PPH operation in this embodiment includes an open ring 1 made of elastic material that can be inserted into the anal canal, and two ends of the opening of the open ring 1 are respectively provided with a The rod body 2a held by a person, adjusting the distance between the two rod bodies 2a can adjust the diameter of the split ring 1, and the split ring 1 is evenly provided with a plurality of baffles 3 extending axially along the split ring 1. The blocking plate can make the mucosal tissue exposed between the opening ring 1 and the distal end surface of the anorectal dilator appear segmented, which solves the problem that it is difficult to grasp the depth of needle insertion when inserting the needle on the continuously raised mucosa. Preferably, the free end of the blocking piece is bent toward the axis of the split ring, so that when the rod body 2a is p...

Embodiment 3

[0028] Example 3 Anorectal PPH operation guide stapler

[0029] like Figure 5 As shown, the guide stapler for anorectal PPH operation in this embodiment includes an open ring 1 made of elastic material that can be inserted into the anal canal, and two ends of the opening of the open ring 1 are respectively provided with a The rod body 2a held by the person, adjusting the distance between the two rod bodies 2a can adjust the aperture size of the split ring 1, the split ring 1 is bent from a sheet elastic material, and the outer peripheral surface of the split ring 1 Three elongated through-hole grooves 4 are evenly opened on the top, and the length direction of the through-hole grooves 4 is perpendicular to the axial direction of the split ring 1. Specifically, for the convenience of the smooth removal of the split ring 1 after suturing, each adjacent two A slit allowing the suture to pass should be provided between the through hole grooves 4 . When the anorectal seam guide ...

Abstract

The invention discloses a guide suture instrument for an anorectal PPH operation. The guide suture instrument comprises an open ring which is made of elastic materials and can stretch into the anal tube, rods capable of being held by human hands are arranged at the two ends of the open position of the open ring respectively, and the caliber of the open ring can be adjusted by adjusting the distance between the two rods. According to the guide suture instrument for the anorectal PPH operation, a doctor can be assisted in guaranteeing the purse string suture position and depth and the purse string completeness precision in the PPH operation process, and the situation that the operation effect is poor, and the subsidiary injury occurs due to the fact that the purse string suture position and depth are controlled improperly in the former PPH operation is effectively avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to a guiding stapler for anorectal PPH operation. Background technique [0002] Minimally invasive hemorrhoid surgery (PPH), also known as stapler hemorrhoidal circumcision, is a new technique using stapler to treat circular prolapsed hemorrhoids. In recent years, it has been widely used in various types of hemorrhoids, especially in patients with severe internal hemorrhoids and partial rectal mucosal prolapse. The principle of PPH surgery is: to retain the anal cushion, and perform an instantaneous anastomosis while circularly resecting and anastomating some internal hemorrhoids, the mucosa on the hemorrhoids, and submucosal tissues. It not only blocks the blood supply of the hemorrhoid, but also suspends and fixes the slipped tissue, and restores the pathological anorectum to its normal anatomical state. In the past, in the PPH operation, in addition to the most basic PPH stapler, an anorecta...
