Problems solved by technology

The difficulty of this technique is that when the tunnel walls on both sides are finally resected, the tunnel walls collapse due to resection; at the same time, the superficial mucosa on the top of the tunnel shri

Embodiment Construction

[0028] Referring now to the accompanying drawings, the present invention will be further described.

[0029] Such as Figure 1-6 As shown, an endoscopic submucosal tunnel supporter consists of a head 1, a skeleton 2, an insulating layer 3, a tail 4, a recovery line 5, a push rod 6, an outer sheath 7, an outer sheath handle 8, a pipe jacking handle 9, etc. Partial composition. Among them, the head 1, the skeleton 2, the insulating layer 3, and the tail 4 constitute the supporter body 10, and the shape of the supporter body 10 is a three-dimensional geometric body with an internal hollow shape such as a spherical shape, a cylindrical shape, or a diamond shape. Several filiform skeletons 2 start from the head 1 and end at the tail 4, and are arranged at a certain angle in the radial direction. The insulating layer 3 covers the skeleton 2 . The recovery line 5 is a thread, which passes through the gap between the skeleton 2 near the tail 4, and forms a closed-loop structure by ...

Abstract

The invention discloses an endoscopic submucosal tunnel support which is characterized by comprising a head, a framework, an insulating layer, a tail, a recycling wire, an ejector rod, a sheath, a sheath handle and an ejector rod handle. A support body comprises the head, the framework, the insulating layer and the tail; the recycling wire penetrates thread gaps, which are close to the tail, of the framework; a conveyor comprises the ejector rod, the sheath, the sheath handle and the ejector rod handle; the ejector rod is positioned in the sheath and can axially move; the support body is preliminarily compressed and gripped in the sheath and can be completely pulled away from the sheath after being released, and the original spatial stereoscopic geometric shape of the support body can be restored; the recycling wire can be hooked, dragged and pulled, so that the support body can be withdrawn. The endoscopic submucosal tunnel support has the advantages that tunnels can be effectively supported by the endoscopic submucosal tunnel support when tunnel walls are excised during endoscopic submucosal dissection, accordingly, complications such as perforation and inherent muscular layer injury can be reduced, and the excision efficiency can be improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a tunnel supporter for endoscopic submucosal dissection. Background technique [0002] Endoscopic submucosal dissection is an important technique for complete resection of early gastrointestinal and esophageal cancer through gastroscopy and colonoscopy. The basic principle of the technique is to inject liquid into the submucosa through an injection needle under the guidance of a gastroenteroscope to separate the mucosa from the muscular layer, and then gradually separate the submucosa through a variety of electric scalpels to completely peel off the surface mucosa from the muscular layer. . The tunneling technique is a commonly used technique in dissection. The method is to establish tunnel openings on the anal side and oral side of the lesion, and then gradually separate the submucosa with an electric knife from the oral side to the anal side, and finally connect with the anal opening to fo...
