Description

High-frequency treatment device

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a high-frequency treatment instrument.

Background

Endoscopic Submucosal Dissection (ESD) refers to an Endoscopic minimally invasive technique that utilizes high frequency instruments to perform submucosal dissection of lesions larger than 2 cm. ESD indications are primarily early stage digestive cancers or precancerous lesions with very low lymph node metastasis rates, comprising the steps of: marking, submucosal injection, circumcision, mucosa stripping, wound surface treatment and specimen treatment.

In the traditional technology, marking, circumcision and mucosa stripping can be realized through a high-frequency electrotome; the submucosal injection can be realized through the injection needle; the treatment of the wound surface can be realized through the electric coagulation forceps. In the mucous membrane stripping process, the submucosal injection can lift the focus and separate the focus from the muscular layer, which is beneficial to finishing the focus excision without damaging the inherent muscular layer and reducing the occurrence of complications such as perforation, bleeding and the like.

Currently, a side hole is usually formed on a tail end insulating part at the far end of the outer tube for submucosal fluid infusion. Because the side hole is a large-diameter end face hole, the side hole cannot be pricked into the submucosal layer like an injection needle, and therefore, liquid leakage is caused during fluid infusion, and the mucosa bulging effect is poor. Meanwhile, in the prior art, an original injection hole (or an injection hole) can be integrated on the electrode, the outer tube is used as an injection channel, and a side hole is formed at the near end of the electrode.

However, in the conventional technology of the electrode integrated liquid injection hole, the electrode has the functions of treating mucosal tissues and injecting liquid to submucosal layers, and tissue adhesion is inevitably generated when the electrode is used for treating the mucosal tissues, so that the liquid injection hole of the electrode is blocked and liquid injection cannot be performed.

In order to solve the problem of blockage of an electrode injection hole, the electrode is usually taken out of a body, scabs on the surface of the electrode are removed, and then a rod-shaped object smaller than the inner diameter of the electrode is inserted into the electrode for dredging, but the inner diameter of the electrode is usually smaller, the rod-shaped object for dredging needs to be very thin and sharp, so that the dredging can be completed, an operator is easily accidentally injured in the using process, the electrode is easily lost, the pollution is easily caused, and the electrode is inconvenient to use.
