Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a polyp extraction device of an endoscope.
Background
Endoscopes are a commonly used medical instrument, and most of currently used electronic endoscopes generally include: the endoscope comprises a front end part, a bending part, an insertion tube, an operation part, a joint part and a light guide optical cable connected with the external light source, which are sequentially connected. The front end part is a hard part of the endoscope and is provided with a plurality of small holes and windows, namely an air supply and water supply outlet hole, a biopsy channel outlet hole, an objective lens and a light guide window. The bending part is positioned between the front end part and the insertion tube, and can bend in different directions so as to realize multi-angle observation of the front end part. The insertion tube accommodates therein an air/water feeding valve passage communicating with the air/water feeding outlet hole, a biopsy passage communicating with the biopsy passage outlet hole, a light guide beam connected to the light guide window, and an image guide beam connected to the objective lens. When in use, the front end part, the bending part and the insertion tube of the endoscope enter the human body through the natural duct of the human body or through a small incision made by operation, and can directly peep for the change of the related parts. The biopsy channel openings of the current endoscope are all positioned below the operation part and are biopsy forceps and various therapeutic instrument insertion openings, and the biopsy forceps and various therapeutic instruments are inserted and then extend out from the biopsy channel outlet hole at the front end part through the biopsy channel.
Polyps, which are unwanted swelling that grows on the surface of human tissue, are commonly referred to as polyps in modern medicine as neoplasms that grow on the surface of human mucosa. Patients with polyps, typically after resection by high frequency electrical trepanning under an endoscope (e.g., a gastroscope), need whole tumor removal for pathological biopsy. The aperture of a biopsy channel of a common electronic endoscope is generally 2.8mm-3.5mm, and only polyps with diameters smaller than 5mm can be taken out; for polyps with the diameter of more than 5mm, when the polyps are removed under an endoscope, the polyps need to enter a human body through a special object grabbing clamp to be taken out or the objective lens surface at the front end part of the endoscope needs to be sucked through negative pressure to exit along with the front end part of the endoscope; the polyp which is partially resected slides into the intestinal cavity, is difficult to grasp, and a doctor gives up grasping, so that the patient is required to pay attention to discharge the polyp out of the body along with the stool, and then the biopsy is carried out; for multiple polyps, after the polyps are required to be grasped and exit the endoscope, the endoscope is advanced again, a second polyp is searched, the polyps are excised again, the operation is repeated, the pain of a patient is increased, and meanwhile, the operation is delayed, so that a lot of inconvenience is caused.
