Embodiment 1

[0041] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a PPH auxiliary device close to the anal canal of the present invention. A PPH auxiliary device that is close to the anal canal, the PPH auxiliary device that is close to the anal canal includes an anal canal dilator body 1, and a mucosal protection plate 2 on hemorrhoids; the anal canal dilator body 1 is matched with a hemorrhoid Upper mucosal protection plate 2.

[0042] Please refer to figure 2 , figure 2 It is a structural schematic diagram of the anal canal dilator body 1 . The anal canal dilator body 1 includes an anus expansion part 11 and a limiting part 12; the limiting part 12 is provided with a hollow hole 13.

[0043] Please refer to image 3 , image 3 It is a structural schematic diagram of the mucosal protective plate 2 on hemorrhoids. The hemorrhoid mucosa protection plate 2 includes a main body plate 21 and an outer side plate 22; the main body plate 21 and the outer s...

Embodiment 2

[0051] Please refer to Figure 4 , Figure 4 It is the structural representation of embodiment 2. This embodiment is basically the same as Embodiment 1, the difference is that the main body 1 of the anal canal dilator in this embodiment is provided with a fitting wire groove 3, and the main body plate 21 on the corresponding hemorrhoid mucosa protection plate 2 Fitting line rails are provided; said fitting line rails are matched with the fitting wire slots 3 . In this embodiment, the upper hemorrhoidal mucosa protection plate 2 and the anal canal dilator body 1 are matched by the fitting line groove 3 and the fitting line rail. The direction is determined, which can accurately reach the area to be protected by the mucosa. On the other hand, the mucosal protection plate 2 on the hemorrhoids can be closely attached to the anal canal dilator body 1 without falling off and shifting, ensuring that the hemorrhoids can be protected during the entire operation. Both can protect the...

Embodiment 3

[0054] Please refer to Figure 5 , Figure 5 It is the structural representation of embodiment 3. This embodiment is basically the same as Embodiment 1, the difference is that a locking buckle 4 is provided on the outer plate 22 of the hemorrhoidal mucosa protection plate 2 in this embodiment; one end of the locking buckle 4 is hinged on the outer plate 22 The outer surface, the other end is the free end. In this embodiment, by setting the locking buckle 4, and the locking buckle 4 is fixed on the outer side plate 22 through a hinged manner, and has a degree of freedom of rotation. edge, thereby realizing the locking effect on the rectal mucosa protection plate, so as to realize the tight fit of the hemorrhoids mucosa protection plate 2 on the anal canal dilator body 1.

[0055] A PPH auxiliary device of the present invention that is close to the anal canal can be close to the anal canal dilator, and has a good protective effect on the rectal mucosa; the anal canal dilator ...

Abstract

The invention relates to a PPH auxiliary instrument closely attached to the anal canal. The PPH auxiliary instrument closely attached to the anal canal comprises an anal canal dilator body and an upper hemorrhoid mucosa protective plate. The PPH auxiliary instrument comprises an anal canal dilator body and a hemorrhoid mucosa protective plate. The anal canal expander is matched with an upper hemorrhoid mucosa protection plate on the body. The anal canal expander body comprises an enlarged anus part and a limiting part. The inner surface of the main body plate is an inner concave arc surface. The radian of the concave arc surface is consistent with the radian of the anal expansion part. The outer surface of the outer side plate is an outer convex arc surface. The radian of the convex arc surface coincides with the radian of the limiting portion. The PPH auxiliary instrument of the invention has the advantages that the PPH auxiliary instrument is closely attached to the anal canal, the upper mucosa plate of the hemorrhoids is adopted with an arc design, the PPH auxiliary instrument can be closely attached to the anal canal dilator, and the rectal mucosa has good protective effect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a PPH auxiliary instrument close to the anal canal. Background technique [0002] TST (Tissue-selecting Therapy stapler) minimally invasive technique, also known as selective hemorrhoidal mucosal anastomosis, is praised as the safest minimally invasive technique so far by the anorectal diagnosis and treatment circle. new technology. TST minimally invasive surgery uses a special anorectoscope to form different open-loop windows, uses an anastomotic probe to lock the hemorrhoids, and adjusts the resection range of the hemorrhoidal mucosa according to the size and number of hemorrhoids, maximizing the protection of the normal function of the anus. [0003] Minimally invasive surgery, also known as selective suprahemorrhoidal mucosal anastomosis, has been praised as the safest minimally invasive technique so far by the anorectal diagnosis and treatment circle. It is a ne...
