Abstract
The invention provides a foreign matter taking-out device for a digestive system department, which effectively solves the problem that foreign matters entering an esophagus mostly comprise fishbone, fruit stone, bone spur and the like, and the foreign matters have sharp parts, so that the esophagus is easily damaged if the foreign matters are not taken out as soon as possible.
Description
Technical Field
The invention relates to a medical instrument, in particular to a foreign body taking-out device for a digestive system department.
Background
The etiology of the foreign body of the esophagus is simple, 98% of the foreign body is formed by the mis-pharynx according to statistics, and the common reason for the mis-pharynx is that the foreign body of the esophagus is a child: A. children are reluctant to have sex, like to put coins, badges or other small articles into the mouth, and can be swallowed into the esophagus occasionally by carelessness; B. the swallowing function is not perfect, and the patient can swallow the food carelessly by eating the food with bones, thorns or kernels; C. cry or play is eaten, and the foreign matter is easy to swallow the food in the mouth or swallow wrongly; D. teeth are not fully ground, and food is swallowed without being chewed well, causing esophageal foreign bodies.
Common causes of esophageal foreign bodies in adults: A. when people eat the food urgently or the people do not concentrate the spirit, the fishbone, the chicken bone and the meat bone are mistakenly swallowed into the esophagus; B. the false teeth are too loose, the food viscosity is too high or the oral mucosa feels hypo, so that the false teeth fall off and enter the esophagus along with the food; C. the awakening degree is low during sleeping, the false teeth fall off, and the false pharynx enters the esophagus by mistake; D. the tiny nucleus and bony spur mixed in the food are mistakenly swallowed into the esophagus; E. the esophagus has the diseases of lumen stenosis, spasm and the like; F. swallowing dysfunction and pharyngeal sensory deterioration to cause pharynx error; G. bad working habits, such as carpenters, shoemakers or finishers holding nails, screws, etc. in the mouth and carelessly swallowing them; H. patients who are anesthetized but not conscious, coma or psychosis may have a mistaking throat when they are unconscious; I. to kill the disease without causing the disease.
The types of foreign matters include various foods, fruit stones, coins, toys, etc., and any substance that can enter the mouth may become foreign matters. Esophageal foreign bodies are generally classified into four major groups, animal type, plant type, metal type and chemical type. Most people report animal-type foreign bodies, and Nandi et al report that animal-type foreign bodies are 84%. Because the types of food and drink are different in different countries and different regions, the difference of cultural life habits is large, and the types and the proportion of the foreign matters in the esophagus are also different. Jujube pits and bones are common in the north of China, and fishbones, shrimps, shells and the like are mainly used in the coastal areas along the rivers in the south. Foreign reports are most common with bones, needles, coins, and dentures.
Therefore, foreign matters entering the esophagus are mostly formed by fish bones, fruit pits, bone bones and the like, but the foreign matters have sharp parts, so that the esophagus is easily damaged if the foreign matters are not taken out as soon as possible, and the foreign matters cannot be directly taken out by using a tool such as a foreign matter forceps and the like because the foreign matters have the sharp parts, so that the esophagus is easily damaged if the foreign matters are directly taken out.
