Appendix primary-secondary endoscope

Abstract

The invention discloses an appendix primary-secondary endoscope. The appendix primary-secondary endoscope integrates the functions of examination and treatment, and comprises a primary endoscope and a secondary endoscope, wherein the primary endoscope is a colonoscope used clinically; the secondary endoscope is a flexible endoscope of which the outer diameter is 9-10F and the length is 140-180 centimeters; a primary endoscope instrument pipeline is formed on the primary endoscope; the secondary endoscope is arranged in the primary endoscope instrument pipeline, and can advance and retreat freely in the primary endoscope instrument pipeline; during examination and treatment, the secondary endoscope passes through the primary endoscope instrument pipeline on the primary endoscope after the primary endoscope reaches cecum, and enters an appendix cavity for examination and treatment. Furthermore, the secondary endoscope consists of a secondary endoscope light source, a secondary endoscope electronic camera and a secondary endoscope instrument pipeline, wherein the diameter of the secondary endoscope instrument pipeline is 1.2 millimeters; the secondary endoscope can be used for injecting water for flushing the appendix cavity through a guide wire, performing biopsy on appendical lesions through secondary endoscope biopsy forceps, and extracting appendiceal fecalith through a secondary endoscope stone extraction instrument (such as a stone extraction basket or balloon).

Description

Technical field: [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a mother-in-law appendix mirror. Background technique: [0002] The appendix is ​​a tubular organ that opens in the cecum, located 2-3 cm below the ileocecal valve, about 5-10 cm long, 0.5-0.7 cm in diameter, and has an earthworm-like shape. At present, there is no endoscope that directly enters the appendix cavity for inspection and treatment in clinical practice. The diagnosis of appendix diseases currently mainly relies on methods such as B-ultrasound, barium meal fluoroscopy, and CT. Since the appendix cavity is relatively thin, the outer diameter of the endoscope that can enter the appendix cavity must be less than 0.5 cm. The appendix is ​​located in the cecum of the human body, which is far away from the anus. An appendix endoscope with a diameter of less than 0.5 cm cannot pass through the nearly 1-meter-long curved colon without the support and ...

AI Technical Summary

Problems solved by technology

The colonoscope currently used clinically has a length of 130 cm and an outer diameter of 1.4 cm, which can pass through the colon to reach the opening of the appendix in the cecum, but cannot enter the appendix cavity because the outer diameter is too thick
