Description

Measure and analyze the track of health cavity organ and the device of angle

Technical field

This utility model for example relates to, for measuring track and real-time angle device, the body internal organs cavity organ in biology or non-biological structures.For the application of field of biology, by from the outside adaptable opening of health by the catheter introducer official.This conduit comprises sensor, such as gyroscope and accelerometer.At it, by the process of cavity organ, sensor can be independent, or combine with other sensor or stimulating technology, and catheter trajectory and crooked data are provided.

Background technology

The human viscera organ has different functions.The geometry of some organs is tubulose, and one of its function is for transmitting the content of tube chamber, as the blood in blood vessel and heart, and the urine in urinary tract and the liquid in gastrointestinal tract and semisolid content.This utility model is applicable to all tube chamber internal organs, the hollow structure of inorganic matter even, but preferred application is at gastrointestinal (GI) road and urinary tract.

Gastrointestinal tract is comprised of different tube chamber shape organs, as pharynx, and esophagus, stomach, small intestinal and large intestine comprise rectum.The tube wall muscle specialization that connects different piece becomes so-called sphincter, and generally sphincter is that different chamber portion by these of closing is separated.Sphincteral function is regulate organ content flow and prevent adverse current (backflowing).A lot of diseases are relevant with caused symptom with the internal organs dysfunction, as gastrointestinal tract, and urinary tract and cardiovascular system.Symptom is usually that source is not clear.The gastrointestinal example has gastroesophageal reflux disease (GERD), Non-erosive reflux disease (NERD), functional dyspepsia, irritable bowel syndrome and fecal incontinence.At urinary tract, urinary incontinence or partial blockage may occur.Yet, in clinical practice, often be difficult to confirm specificity and its real origin of symptom.The task of top priority is a kind of equipment of exploitation and method, and it can provide the data of internal organs normal function and geometrical property, and can be analyzed dysfunction and the symptom of internal organs.Such equipment and method, also can be used for treatment assessment, in the interventional therapy process, gives P&S instructing (as the endoscopic procedure of anti-stream is rebuild and prevented to surgical operation).

Developed up to now the function of a lot of method research internal organs.Certain methods comprises pressure record, and pH value is measured, chemical measurement, and medical image, etc.Other technology comprises the bladder to the placement in the internal organs pipe, for test function, excites symptom or treatment various disease.

As everyone knows, the function of hollow organ's angle of bend and organ is relevant with symptom.For example, once had theory to think, it is extremely important that the angle that esophagus enters stomach enters backflowing of esophagus to acid from stomach, and the anorectal angle is extremely important to defecation.As if for example to enter esophagus relevant for the moment of lower oesophageal sphincter lax (TLESPR) and acid reflux, and this is correlated with and depends on sphincteral compliance under esophagus, enter the angle of stomach and diaphragm foot (be esophagus while passing through diaphram and the angle between diaphram).

Except the data to obtaining by medical image are carried out loaded down with trivial details analysis, in above-described method, neither one can provide the angle information of organ specific part.At present, about the analysis at anal orifice and rectal intestine angle, can estimate by the defecation video, because when defecation, anus and rectum junction move down, so the anal orifice and rectal intestine angle can be in the defecation pre-test.Yet such research is because radiation and the tediously long analysis of radiation seem very inconvenient.Therefore, we need new technology to take measurement of an angle and geometry or the mechanical measurement relevant to organ dysfunction.At present existing many sensors, comprise gyroscope, and their size makes places these sensors at inside of human body and become possibility.

Endoscope is widely used by modern medicine.They are mainly used in watching gastrointestinal inside, and with tissue biopsy, but they are not used to the measurement of other type usually.In order to see more clearly, the doctor generally can rotate or bendable endoscope.Describe a kind of device in CN102711587A, can enter human body, thereby assisted a physician better clearer bat CT sheet.Perhaps, this device can be arranged on the endoscope for some organ temporarily.It contributes to locate various body structures, but depends on imaging technique, as CT.In addition, do not comprise the mensuration of orientation in this class technology, do not comprise for example advanced person's gyroscope equipment in this utility model.

A kind of device has been described in CN101632572A, be a multiarticulate endoscope, can be crooked and with a lot of sensors.Its main purpose is movable more convenient in intestinal, and reduces pain to patient.This utility model main distinction with it is, comprises one or more gyroscopes, is provided at details and the orientation of one or more locational mobile devices.In addition, this utility model does not need the doctor to carry out specially bending apparatus, because this utility model device is very soft, thereby can pasting the flexural measurement of intestinal tendency and change angle.

US 6,216, in 028B1, are described to, and determine position and the direction of medical treatment device in vivo by a kind of method.This technology mainly Magnet based on equipment can be sent to a plurality of Magnetic Sensors that are arranged on the outer equipment of human body.The shortcoming of this patent is not measure the position with phase magnet.The shortcoming that another one is very large is, it can only comprise a Magnet, and the utlity model has the azimuthal measurement of degree of precision and one, can and provide the mobile device of detailed data along the organ linear measure longimetry, and this mobile device comprises a plurality of gyroscopes.Another one advantage of the present utility model, thus be to carry out concrete mathematical calculation according to a plurality of gyrostatic data.

CN101048100A is a kind of device that can obtain the body internal information, and it comprises the electrical stimulation device to surrounding tissue.The main aspect that this utility model is different from it, be that this utility model does not contain the electricity irritation setting, and CN101048100A do not contain core element of the present utility model yet, and one contains gyrostatic capsule, and concrete data and definite orientation can be provided.
