Magnetic traction tool for focal mucosa resectionTechnical Field
The invention relates to a magnetic traction tool for focal mucosa resection, and belongs to the technical field of focal mucosa resection operations.
Background
Focal mucosal resection is a common medical means, is mainly used for resecting diseased mucosal tissues so as to achieve the aim of treatment, and is a complete resection process of diseased mucosal tissues through a specific surgical instrument under the observation of an endoscope. The principle is that the amplifying and lighting functions of the endoscope are utilized to accurately observe the lesion part, then the lesion mucous membrane is accurately resected by a surgical instrument, the main methods of the lesion mucous membrane resection include endoscopic submucosectomy (EMR) and Endoscopic Submucosal Dissection (ESD),
When the ESD operation is utilized, after the focus is cleaned, a specific technology is used for observing and defining the edge according to the pathological type of the focus, an electrotome is used for marking the pathological range at the periphery of 5-10 mm of the edge, physiological saline, epinephrine saline or sodium hyaluronate injection is used for injection, the condition of lifting is observed, the electrotome is used for carrying out peripheral incision, and the focus is peeled off layer by layer under the mucous membrane, so that the focus is completely resected.
In actual focus mucous membrane excision operation, because the operation area scope is narrow and small, after carrying out the peripheral mucous membrane of focus and drawing out, peel off operation difficulty, extremely test doctor's operation experience, and the mucous membrane is drawn out and is influenced by the focus position, is difficult to realize peeling off in different directions, is difficult to get rid of fast after making mucous membrane excision, influences the smoothness of operation, increases the degree of difficulty for operation, also leads to other positions mucous membrane impaired problem because of the operation difficulty easily.
