Description

Appendix intubator

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to an appendix intubator.

Background

Appendicitis, an inflammatory change of the appendix due to various factors, is an abdominal surgical disease. It is a common disease whose prognosis depends on whether a timely diagnosis and treatment is given. Early diagnosis and treatment, patients can recover within a short period, and the death rate is 0.1-0.2%; if delayed diagnosis and treatment can cause serious complications and even death. Clinically, it is often manifested by pain in the lower right abdomen, increased body temperature, vomiting and neutrophilic granulocytosis. Appendicitis is currently classified into acute appendicitis and chronic appendicitis.

The typical clinical manifestations of acute appendicitis are a gradual apparent or aggravating dull pain in or around the upper abdomen, with the abdominal pain shifting to the lower right after hours. Often accompanied by inappetence, nausea or vomiting, and no obvious general symptoms except low fever and hypodynamia at the early stage of onset. Chronic appendicitis refers to chronic inflammatory lesions of the appendix, such as fibrous connective tissue hyperplasia of the vessel wall, stenosis or occlusion of the lumen, distortion of the appendix, adhesion to surrounding tissues, etc., which remain after acute inflammation of the appendix subsides. Chronic appendicitis can be acutely caused by various complex reasons such as improper treatment, environmental factors and the condition of patients.

Appendectomy is generally advocated for appendicitis at present. However, the research results of the emerging modern science, especially the progress of modern immunology, suggest that: the appendix has abundant lymphoid tissues and is involved in the immunologic function of the matrix. According to the research, the human appendix has B lymphocytes and T lymphocytes, which are equivalent to the structure of the bursa of birds, are attributed to central immune organs, and are responsible for the specific functions of the body such as cellular immunity and humoral immunity. The latest research results also prove that the appendix still has secretory cells, can secrete a plurality of substances and digestive enzymes, and promotes the hormone with the intestinal tract peristalsis promotion, the hormone related to growth and the like. In addition, the development of transplant surgery has also suggested to the clinician: the appendix has complete inner circumflex and outer longitudinal muscle, has certain length and pipe diameter, and with the development of microsurgery, the operation of replacing the defect and the stenosis of some pipelines such as ureter and urethra by autologous appendix transplantation is increasingly widespread, so the indication and the crowd of appendectomy should be strictly controlled, and the appendectomy needs to be carried out with great care. Therefore, treatment for appendicitis without excision is of great interest. In recent years, colonoscopy has achieved excellent clinical effects by performing irrigation and drainage on inflamed appendices, and this Endoscopic retrograde appendiceal treatment technology (ERAT) has been widely developed in hospitals at all levels in our country. However, the insertion is difficult due to the structural characteristics of the appendix cavity, and no special appendix introducer exists, so how to enter the appendix cavity to implement treatment needs to be solved.
