Endoscopic electrocoagulation aspirator and application thereof

Abstract

The invention relates to an endoscopic electrocoagulation aspirator comprising an aspirator bar, a handle, a connecting line and a plastic hose. The aspirator bar, the handle and the plastic hose are all hollow and are communicated with one another. The handle is provided with a switch. The aspirator bar and the handle are not collinear. The aspirator bar is composed of an electrocoagulation tube, a metal layer and a plastic protective layer sequentially from inside to outside. The electrocoagulation tube is greater than 2mm in inner diameter; the plastic protective layer is less than 4mm in outer diameter. The section of each of the left ends of the electrocoagulation tube, the metal layer and the plastic protective layer is 20 degrees to 40 degrees angled to a plumb line. The left end of the electrocoagulation tube is provided with an electrocoagulation head extending out; the electrocoagulation head is L shaped; two perpendicular parts of the electrocoagulation head are smoothly connected. The invention further provides an application of the endoscopic electrocoagulation aspirator. The endoscopic electrocoagulation aspirator has the advantages that the aspirator allows aspiration and electrocoagulation to be performed in the same time, the body structure of a patient and operating habits of a surgeon are satisfied, and the aspirator is convenient to use, simple in structure and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscopic electrocoagulation aspirator and its application. Background technique [0002] Endoscopic electrocoagulation aspirator is a commonly used medical device in surgery. It is mainly used for intracavitary surgery. Because the space in the cavity is relatively narrow, the aspirator is directly used as an electrocoagulator to reduce the mutual influence between surgical instruments, which is more beneficial Surgical operation. [0003] At present, the common electrocoagulation suction device has the following problems: 1. During the operation, the doctor's hand is easy to block the line of sight; 2. The straight-line electrocoagulation head is not conducive to the doctor's operation and needs to be bent; 3. The size of the electrocoagulation suction device is not enough Reasonable; 4. The metal layer of the head is exposed too much. [0004] Chinese patent ...

Problems solved by technology

[0003] At present, the common electrocoagulation suction device has the following problems: 1. During the operation, the doctor's hand is easy to block the line of sight; 2. The straight-line electrocoagulation head is not conducive to the doctor's operation and needs to be bent; 3. The size of the electrocoagulation suction device is not enough Reasonable; 4. The metal layer of the head is exposed too much

[0005] But there is no report about a kind of endoscopic electrocoagulation aspirator and application that can overcome the above problems
