Description

Active wireless digestive tract capsular endoscope probe

Technical field

The present invention is about a kind of design of medical treatment device, particularly about a kind of active wireless digestive tract capsular endoscope probe.

Background technology

Endoscope apparatus is existing historical for many years in the application of digestive tract disease diagnosis and treatment, wherein the digestive tract endoscopy can be divided into upper digestive tract endoscopy, small intestinal endoscopy, endoscope antidromicity gallbladder pancreatic ductography and low gastrointestinal endoscopy etc., when implement checking, the control that need turn to the digestive tract endoscope.And the at present normal known endoscope system that uses has to cost an arm and a leg, reuse and may cause cross infection, detects the position and be subject to shortcomings such as esophagus, stomach and large intestine, wherein the conduit diameter of endoscope is thicker, easily cause patient frightened and uncomfortable, for example: patient is too strong as if the reflection of patient's throat when gastroscopy, have cough or vomiting situation always, then have later the situation generation of laryngalgia in gastroscopy.

Therefore, in the industry cycle constantly research and develop and renewal technology, and consider that under the optimized detection mode of person under inspection develop a kind of capsular endoscope, it is a capsular kenel, be provided with image capture unit and image output in inside so that the application in the treatment to be provided.

Summary of the invention

The technical problem that institute of the present invention desire solves:

Human body intestinal canal is made up of many gauffers, and the image capture unit of capsular endoscope is fixing usually at one end, make that capsular endoscope can only the capture at random along with enterogastric peristalsis in human body intestinal canal, therefore the endoscope of capsule kenel is subject to the orientation of capture in human body intestinal canal, makes that the effect that detects is desirable not to the utmost.

Moreover to so far, capsular endoscope on the market is all non-ACTIVE CONTROL, that is capsular endoscope advances in digestive system aimlessly, and can only advance and can not retreat, so can't be in detail and examine the place that condition of illness may be arranged effectively closely.Because human small intestine's internal diameter is very little, about 2.5 centimeters of average diameter, capsular endoscope advances along with small intestinal peristalsis, can be to the tube chamber photography of whole small intestinal, but before entering small intestinal, capsular endoscope rolls along with the wriggling of stomach everywhere in the human stomach the inside, and, along with stomach size in vivo changes, have 300ml capacity (also expansible to the 1500ml capacity) at least, capsular endoscope can't be fixed a point under one's belt or be watched same position back and forth, causes some position of human stomach can't obtain image data, cause the doctor to check in detail, and then have influence on the result of diagnosis diseased region.

Edge this, purpose of the present invention promptly provides a kind of active wireless digestive tract capsular endoscope probe, in digestive tract, advance, retreat and be positioned at diseased region detailed inspection in addition by the magnetic force ACTIVE CONTROL capsular endoscope that it produced, to improve the problem that the conventional capsules endoscope is suffered from.

The technological means that the present invention deals with problems:

The present invention includes a probe grip part, at least one magnetic generation module and a magnetic and produces control circuit for the technological means that problem adopted that solves known technology is a kind of active wireless digestive tract capsular endoscope probe.Magnetic generation module and magnetic produce control circuit and are arranged in the probe grip part, the probe grip part has a magnet unit accommodation space and setting at least one magnetic field intensity operated key thereon, and the magnetic field intensity operated key includes a magnetic field amplification key and a magnetic field range of decrease key.

The magnetic generation module includes a magnetic conductive component and the winding coil at the magnetic conductive component outer ring surface, and magnetic conductive component and coil configuration are in the magnet unit accommodation space of probe grip part.

When a capsular endoscope carries out image capture in digestive tract, the magnetic of active wireless digestive tract capsular endoscope probe of the present invention produces control circuit and produces the coil of an excited signal to the magnetic generation module, make coil produce an electromagnetic field and make magnetic conductive component magnetization, promptly so-called electric magnet because of electromagnetic induction.Described electromagnetic field is formed with a combination field in conjunction with the Distribution of Magnetic Field front end of magnetic conductive component in the probe grip part, and passes through the magnetic field intensity of magnetic field amplification key and the described combination field of magnetic field range of decrease key modulation, with the magnetic chucking power between control capsular endoscope and probe.

In a preferred embodiment, the magnetic generation module can be a permanent magnet, and in an other embodiment, and the magnetic generation module includes a permanent magnet and the winding coil at the permanent magnet outer ring surface.The magnetic field that the magnetic generation module produces can influence the action of capsular endoscope, makes capsular endoscope be subjected to the control of active wireless digestive tract capsular endoscope probe and navigates in the digestive tract.

The present invention contrasts the effect of known technology:

Via the technology used in the present invention means, utilize the magnetomechanical effects of magnetic generation module to originate as magnetic force, and the magnetic force size by magnetic field intensity operated key modulation magnetic generation module is with the magnetic chucking power between control capsular endoscope and probe, because every examined person's fat or thin size and fat thickness differ, this technological means can be with optimal magnetic adsorbability control capsular endoscope in different examined persons, and then ACTIVE CONTROL capsular endoscope advancing in digestive tract, retreat and be positioned at exactly the diseased region of required detailed inspection, and make the image capture direction of capsular endoscope can keep an orientation, make that the result of human body intestinal is more accurate, improving the known capsules endoscope advances in digestive system aimlessly, can only advance and can not retreat, and the shortcoming that in the human stomach, can't fix a point or watch same position back and forth.

Moreover, various advantages such as the present invention has that simple structure, weight are slim and graceful, easy operating and high-reliability, and can improve traditional endoscope patient's that causes when medical treatment detects misery, and effectively improve doctor's diagnosis capability and improve the method for the treatment of, the further raising ease of use medically and the effect of enhancement industry utilization.
