Description
Technical Field
The invention relates to the field of medical instruments, in particular to a multi-point observation endoscope probe.
Background
Endoscopes generally refer to medical instruments that enter the body through natural orifices or small surgical incisions in the body to observe the internal conditions of the body. The lesion that cannot be visualized by X-rays can be seen with an endoscope, so its help to the physician is obvious. For example, an endoscopist can observe ulcers or canceration in the stomach, and an optimal treatment plan is made according to the ulcers or canceration. Some endoscopes have therapeutic functions, such as laparoscopes, colonoscopes, gastroscopes, bronchoscopes, cystoscopes, and the like.
Endoscopes have two important performance criteria, namely imaging quality and field of view. With the rapid progress of medical imaging, the development of high-definition endoscope imaging technology is greatly promoted, the in-vivo high-resolution imaging is realized, and the imaging quality basically meets the requirements of the existing medicine. However, there is a limitation in the observation field of the endoscope.
The medical endoscope is a common medical apparatus and consists of a host machine, an insertion tube and a probe, wherein the insertion tube can be a hard tube or a soft tube, the tail end of the insertion tube is a cylindrical probe, and an electronic lens or an optical lens is arranged in the insertion tube. The host computer is observed with the cooperation of camera lens. When in use, the probe is guided into a cavity-shaped duct of a pre-examined organ, such as an esophagus, a trachea, an anus and the like, through the insertion tube so as to observe the condition of the inner cavity. Because the probe and the insertion tube are both tubular objects with small diameters and are inserted into the cavity-shaped organ, the inserted probe is often covered by the surrounding organ mucosa, so that the probe can only observe the condition of the front organ mucosa, only one point is used for observation, the observation angle cannot be adjusted, the organ mucosa in other directions around the probe is observed, and the observation field of view is extremely narrow.
Moreover, the angle of the probe of the existing medical endoscope can not be changed after the endoscope is inserted into a patient body, so that the endoscope is single in shooting angle, only one site of a focus can be observed, the practical degree of the endoscope is greatly reduced, the endoscope can be repeatedly pulled out and inserted for use if the observation site is required to be adjusted, and the mode can cause certain damage to the patient. Meanwhile, the existing medical endoscope can only carry out single-point small-range visual field observation on a focus area, the endoscope examination time required by a patient is long, and the patient suffers from pain during examination.
Therefore, designing a multi-point observation endoscopic probe is a problem that we need to solve at present.
