Problems solved by technology

The incision protection retractor in the prior art is composed of an inner snap ring, an outer snap ring and a pipeline, and the inner snap ring is an elastic solid or hollow ring, and the outer snap ring is an elastic solid or hollow elliptical ring or a double ring, and the middle connection The flexible elastic film sleeve design, when in use, the outer snap ring flips and rolls around the sleeve to complete the incision fit, expansion protection, and retraction functions, and does not provide the functions of moisturizing the organs and preventing the return of waste liquid; the existing incision layer protector is provided by the card Composed of ring and polymer film, the clasp is an elastic solid or hollow ring, and the polymer film is a square surgical drapery. When in use, the clasp is placed in the abdominal cavity, and the polymer film is only used to cover the incision and provide moisture for the removed organs. Function, no incision expansion, fitting and retraction function

Embodiment 1

[0028] Embodiment one: if figure 1 a. figure 2 , image 3 , Figure 5 a. Figure 5 As shown in b, a skirt-type incision protection retractor is composed of an outer clasp 1, an inner clasp 2, a thin film tube 3, a skirt 4 and a skirt transition section 4-1. The outer snap ring 1 and the inner snap ring 2 are connected by thermal welding, the outer snap ring is hollow peanut-shaped, the inner snap ring is hollow oval, and the inner and outer snap rings are built with stainless steel alloy reinforcing wires 1-1, 1-2 to increase The snap ring is rigid. The thin film pipe 3 adopts a cylindrical design, and the skirt 4 is thermally connected to the outer snap ring through the skirt transition section 4-1.

[0029] During the operation, the inner clasp is deformed and placed into the incision, the outer clasp is turned over to expand and protect the incision, and the skirt is spread flat on the periphery of the incision.

Embodiment 2

[0030] Embodiment two: if figure 1 d. figure 2 , image 3 , Figure 5 g. Figure 5As shown in h, a skirt type incision protection retractor is composed of an outer snap ring 1, an inner snap ring 2, a film pipe 3, a skirt 4 and a skirt fixing ring 4-2. The ring connection method of outer snap ring 1 and inner snap ring 2 is heat sealing welding, outer snap ring 1 adopts hollow S shape, inner snap ring 2 and skirt fixing ring 4-2 adopt hollow oval shape, inner snap ring, outer snap ring and The built-in stainless steel alloy reinforcing wires 1-1, 1-2, and 1-3 in the skirt fixing ring increase the rigidity of the snap ring. The film pipe 3 adopts a cylindrical design, and the skirt scarf 4 is heat-sealed and connected to the skirt scarf fixing ring 4-2.

[0031] During the operation, the inner snap ring 2 is deformed and put into the incision, the skirt fixing ring 4-2 is placed outside the incision, the outer snap ring 1 is turned over to expand and protect the incision ...

Abstract

The invention innovatively provides a novel skirt-type incision protecting retractor overcoming the defects in the prior art. The design of a skirt-type thin film operation towel is added to an existing incision protecting retractor, and the functions of moisturizing and protecting taken-out visceral organ tissue and preventing blood and waste liquid from flowing back in an operation are achieved. The skirt-type incision protecting retractor is composed of an outer clasp, an inner clasp, a flexible and elastic middle connection thin film pipe and the skirt-type thin film operation towel.

Description

Technical field: [0001] The invention belongs to medical operation supplies, in particular to the protection and retraction of surgical incisions, which are used to expand the surgical field of view, protect the incision tissue from damage, reduce incision tissue planting and infection, moisturize the organs and tissues taken out during the operation, and prevent Blood and waste fluid flow back into the cavity causing infection. Background technique: [0002] Surgical techniques have developed rapidly in recent years, and the protection of surgical incisions and retraction to prevent infection have attracted increasing attention. The entry, operation, and removal of surgical instruments through the incision (or the incision below the hole) will further damage the incision tissue, and the exposed incision is more prone to planting and infection; the irregular shrinkage of the incision or free tissue will hinder the surgical field of view and affect the surgical operation; Th...
