Description
Technical Field
The application relates to the technical field of medical instruments, in particular to an electrically-actuated safety disintegration capsule gastroscope.
Background
Gastroscopy is one of the most common methods used in gastroenterology to examine pharyngeal, esophageal and gastric conditions. The existing gastroscope mainly comprises a lens and a guide core, and when a patient is subjected to gastroscopy, the gastroscope needs to be inserted from the mouth to the stomach, so that the patient is very painful and inconvenient to operate.
In order to change the situation, a capsule gastroscope is designed, namely, a communication device and an image sensor are integrally arranged in a corrosion-resistant capsule, after a patient swallows the capsule gastroscope, the capsule gastroscope starts to photograph digestive tract organs such as the stomach through which the capsule gastroscope passes according to a preset time interval, and the obtained photograph is wirelessly transmitted to an external computer for display for a doctor to check.
In addition, the in-vivo motion of the capsule gastroscope can be positioned and guided by using an in-vitro magnetic control technology. The magnetic component is arranged on the capsule gastroscope, a magnetic field is applied to the human body outside in the capsule gastroscope examination process, and the magnetic force of the magnetic field on the capsule gastroscope magnetic component is used for guiding and controlling the movement direction and the shooting direction of the capsule gastroscope and can also play a role in positioning the position of the capsule gastroscope in the human body. As disclosed in chinese patent 201410141477.1, a capsule gastroscope system with a magnetic field positioning function and a capsule gastroscope thereof are disclosed, wherein the capsule gastroscope is provided with a magnetic field measurement module, when the magnetic field measurement module senses a magnetic field of a magnet arranged around a patient, the magnetic field intensity can be measured and a field intensity signal is generated, then the field intensity signal is sent out through a radio frequency unit, the field intensity characteristics of the magnet can be measured and positioned in advance and a field intensity model is generated, and the field intensity signal and the field intensity model are compared to obtain the position information of the capsule gastroscope.
When the capsule gastroscope is used for photographing the inside of the pharynx, the esophagus and the stomach, the capsule gastroscope is discharged through the lower digestive tracts such as the small intestine, the large intestine and the like of the human body. However, since the capsule gastroscope in the prior art still has the defect of overlarge volume (the total length is 1.5cm-2 cm), and the posture of the capsule gastroscope is not completely controllable in the movement process in the body, when the capsule gastroscope finishes shooting the interior of the stomach and enters a narrow and distorted lower digestive tract, a certain probability exists that the capsule gastroscope is blocked in the lower digestive tract, and the probability is about thousandth according to statistics, so that the probability is not negligible for large-scale clinical application. In particular, once the capsule gastroscope is clamped in the lower digestive tract, the capsule gastroscope is difficult to treat, in-vitro magnetic control guidance is basically ineffective, and if the capsule gastroscope is still difficult to urge out by a medicine means, the capsule gastroscope needs to be taken out by an operation, which not only causes waste of medical resources and economy, but also is a psychological and economic burden for patients, and is unfavorable for the common application of the capsule gastroscope.
