Problems solved by technology

[0003] 1. It is impossible to artificially control the position of the capsule endoscope in the digestive system, so it is necessary to use the peristalsis of the digestive tract to make it move in the digestive tract and take images, that is, it can only be used to diagnose diseases of the digestive tract, while the diagnosis of the esophagus and stomach can only be performed. The use of electronic gastroscope or fiber optic gastroscope (thickness: 0.9~1.2cm) not only brings great pain to the examinee, but also requires a lot of disinfection because of the large size and heavy weight of the electronic gastroscope or fiber optic gastroscope ;
[0004] 2. It is impossible to artificially control the residence time of the capsule endoscope in the digestive system, and it can only collect pictures automatically according to the designed shooting speed (such as 1-3 frames per second). affect the doctor's diagnosis of the disease;
[0005] 3. It is impossible to artificially control the shooting direction of the capsule endoscope in the digestive system, and it is impossible to collect more comprehensive images according to the required angle at will;
[0006] 4. It can only be excreted from the body after passing through the small intestine once, and cannot be used repeatedly, resulting in high inspection costs (5000~8000 yuan / time), which limits the scope of application and is difficult to popularize in the market

Embodiment 1

[0020] Such as figure 1 Shown: there is the same capsule endoscopic body 1 as the prior art, and what is different from the prior art is that the tail end of the capsule endoscopic body 1 is connected with a tail line 2 marked with a scale, and the diameter of the tail line 2 is smaller than 3mm. The tail wire 2 can be fixed on the tail end of the capsule endoscope body 1 by bonding or pouring. Since the tail wire 2 is only responsible for connection, the thinner the diameter, the better if the connection strength is satisfied.

[0021] Embodiment 1 is suitable for the inspection of the esophagus and stomach, and can adjust the tail line 2 left outside the body to control the position and time of the capsule endoscope.

Embodiment 2

[0023] Such as figure 2 Shown: there is the same capsule endoscopic body 1 as the prior art, the difference from the prior art is that the tail end of the capsule endoscopic body 1 is connected with a tail line 2 marked with a scale, and the capsule endoscopic body The head end of 1 is connected with a head wire 3, and the diameters of the head wire 3 and the tail wire 2 are less than 3 mm. The tail wire 2 and the head wire 3 can be fixed on the tail end and the head end of the capsule endoscopic body 1 by methods such as bonding or pouring. Since the head wire 3 and the tail wire 2 only undertake the connection function, they meet the conditions of connection strength. Next, the smaller the diameter, the better.

[0024] Embodiment 2 is suitable for the inspection of the esophagus and stomach, and can control the stay position, time and shooting angle by adjusting the head line 3 and tail line 2 left outside the body at the same time.

Embodiment 3

[0026] Such as image 3 Shown: there is the same capsule endoscopic body 1 as the prior art, the difference from the prior art is that the tail end of the capsule endoscopic body 1 is connected with a tail line 2 marked with a scale, and the capsule endoscopic body The head end of 1 is connected with a head line 3 (the scale can also be marked on the head line), and the diameters of the head line 3 and the tail line 2 are less than 3mm. Wire lugs 4 can be processed at both ends of the head and tail of the capsule endoscope body 1 respectively, and the tail wire 2 and the head wire 3 pass through the wire nose 4 and feed back into double wires. Since the head wire 3 and the tail wire 2 only undertake the connection function, the thinner the diameter, the better under the condition of satisfying the connection strength.

[0027] Embodiment 2 is suitable for the inspection of the esophagus, stomach and intestinal tract, and can control the stay position, time and shooting angle ...

Abstract

The invention discloses a controllable capsule endoscopy which can be used for taking pictures of any parts of the digestive system (such as esophagus, stomach, small intestine and the like) from any angle by manual control, increasing the utilization rate and reducing the diagnosing cost. The controllable capsule endoscopy (1) comprises a capsule endoscopy body, a tail line (2) marked with scales is connected to the tail end of the controllable capsule endoscopy (1), and the diameter of the tail line (2) is smaller than 3 millimeters.

Description

technical field [0001] The invention relates to a capsule endoscope, in particular to a steerable capsule endoscope that can artificially control any position and angle of the digestive system (esophagus, stomach, small intestine, etc.) and can improve utilization and reduce diagnostic costs. Background technique [0002] Capsule endoscopy is a smart capsule with a built-in camera and signal transmission device. After oral administration, the subject moves in the digestive tract with the help of digestive tract peristalsis and takes images. Doctors use the external image recorder and video workstation to understand the entire digestive tract of the subject and make a diagnosis of the condition. It has the advantages of convenient inspection, no trauma, no pain, no cross-infection, and does not affect the normal work of patients. Defects such as the elderly, infirm and critically ill patients. However, the existing capsule endoscopy also has the following disadvantages: ...
