Embodiment Construction

[0018] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0019] Such as Figure 1~6 Shown, a kind of mucosa dissector, it comprises:

[0020] Outerwear components;

[0021] An electric coil 2, an insulating layer 1 is arranged on a part of the electric coil 2, and the remaining part of the electric coil 2 is exposed so as to be used for peeling off the mucous membrane; certainly, there are many kinds of positions for setting the insulating layer 1 on the electric coil 2, such as figure 1 , 2 shown as one such as image 3 , 4 For the other, the specific structures of these two types are: the upper side of the electric coil 2 is mostly exposed, and the rest of the electric coil 2 except the exposed part has an insulating layer 1; Figure 5 , 6 The other is shown, and its specific structure is as foll...

Abstract

The invention discloses a mucous membrane detacher. The mucous membrane detacher comprises an external sleeve assembly, an electric coil, a sliding ring and a pulling rope; part of the electric coil is equipped with an insulation layer, and the rest parts are exposed for detaching a mucous membrane; the sliding ring is arranged on the external sleeve assembly and can axially move relative to the external sleeve assembly; an electrode plug is arranged on the sliding ring; the pulling rope is axially moved to be inserted into the external sleeve assembly; one end of the pulling rope is connected with the electric ring and while the other end of the pulling rope is electrically connected with the electrode plug on the sliding ring. With the adoption of the mucous membrane detacher, tissue can be closed conveniently when detaching the tissue below the mucous membrane; the positioning is accurate; therefore, the operation is convenient and fast; the difficulty of doctors at operation is greatly reduced, and thus the time can be saved; the phenomenon of burning out other good tissues can be avoided.

Description

technical field [0001] The invention relates to a mucosa peeler, which belongs to the technical field of medical instruments. Background technique [0002] At present, in the field of medical endoscopy, endoscopic submucosal dissection is used for the treatment of gastrointestinal lesions, and the purpose of treatment is achieved by peeling off the mucosa where the lesions are located. Mucosal dissectors are often used to remove diseased submucosal tissue or polyps, and are commonly used clinically. Conventional mucosal peelers are complicated to operate, take a long time, have high risks, and have high technical requirements for clinicians, which makes this technology unable to be widely used. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a mucosal stripper, which is convenient to fit the tissue when cutting and stripping the submucosal tissue lesions under the endosc...
