Description

External magnetic control pharmacy thing release capsule system based on digital picture navigation
Technical field
What the present invention relates to is a kind of device of technical field of medical instruments, specifically is a kind of external magnetic control pharmacy thing release capsule system based on digital picture navigation.
Background technology
The modern is owing to work rhythm quickening, diet inequality, cause the sickness rate of digestive tract disease to raise day by day, digestive tract disease becomes the common a kind of disease that influences modern's health, analyze to find that according to statistics digestive tract disease is to becoming younger and hiddenization direction develops.The visual detection of digestive tract disease has important effect for the prevention and the diagnosis and treatment of digestive tract disease, and 9 meters of human body all-digestive tract length overalls, because the digestive tract shape belongs to slender pipeline, be distributed between each organ of trunk, the irregular closure of all-digestive tract structure is to the detection and the treatment of digestive tract disease bring very big challenge clinically.
The visual detection of the digestive tract disease of Shi Shiing mainly contains two kinds clinically: gastrointestinal, intestinal mirror and capsule endoscope two big classes.Gastroscope, intestinal microscopy are surveyed and are belonged to active detecting, can realize all-digestive tract disease " fixed point " diagnosis, but may have the risk that causes stomach wound, intestinal wound in the gastroscope, intestinal microscopy survey process, understand in the testing process and bring huge misery to patient.Capsule endoscope detects and belongs to the noinvasive detection method, can implement the detection of digestive tract disease after patient's oral capsule endoscope, can not bring discomfort or painful sensation to the patient, but capsule endoscope can only be followed gastral wriggling and be carried out diagnosis in patient's digestive tract, the motion of capsule endoscope belongs to passive movement mode fully, capsule endoscope also belongs to " locality " and " randomness " diagnosis for the diagnosis of digestive tract disease, can not implement initiatively " fixed point " diagnosis to digestive tract disease, there is very big blind area in the capsule endoscopy diagnosis overall process, has greatly limited the clinical practice of capsule endoscope in the visual diagnosis of all-digestive tract disease.
On the other hand, when making a definite diagnosis digestive tract and find disease such as disease, the therapeutic scheme that can adopt clinically: can under the video image navigation of gastroscope and intestinal mirror, carry out treatment with upper digestive tract and colon with lower digestive tract for stomach, but still have the risk that causes stomach wound, intestinal wound in therapeutic process, needs of patients bears huge misery in the therapeutic process; And, can't adopt traditional gastroscope and intestinal mirror to treat for the disease that the digestive tract at small intestinal place exists, and must carry out treatment by operation method for the disease that small intestinal exists, this misery that causes for the patient is well imagined.And have the only shoot function of concrete digestive tract image of capsule endoscope now, do not possess and find that digestive tract produces the function that treatment is carried out to digestive tract disease in the back, so can't carry out treatment digestive tract disease.
Find through retrieval prior art, be published in the scientific paper " design and research of drug release microcapsule control circuit " on " modern Manufacturing Engineering " 2009 the 8th phases, announced a kind of microcapsule structure that is used for the digestive tract drug release, be compressed spring and discharge by controlling medicine in the miniature magnetic control system switch messenger drug storehouse.
But there are following two shortcomings at least in the microcapsule that this technology forms: at first, do not have the digestive tract image-guidance to help, can not determine the position of drug release; Secondly operator lacks the ability of manipulation in vitro control microcapsule attitude and position, can not ACTIVE CONTROL microcapsule attitude and position, more than the restriction of two shortcomings, make this patent of invention can't be applied to clinical practice.
