Capsule gastroscope and power supply screw mechanism thereof

Abstract

The invention belongs to the technical field of medical instruments, and particularly discloses a capsule gastroscope and a power supply screw mechanism thereof. The capsule gastroscope comprises an observation cabin which is arranged in the middle of a capsule shell, a transmission screw and an observation mechanism, wherein the side wall of the observation cabin is made of a transparent material; the transmission screw is arranged in the observation cabin and comprises a rod body and a threaded protrusion arranged outside the rod body; and the observation mechanism is arranged on the transmission screw in a transmission manner. A power supply screw mechanism comprises a rod body and a threaded protrusion arranged outside the rod body, wherein spiral grooves cooperating with the threaded protrusion are formed in the inner side wall of the transmission mechanism, each second electrode brush is arranged at the bottom of the corresponding spiral groove, and first electrode brushes are arranged on the inner side wall of the transmission mechanism. The transmission screw drives the observation mechanism to move, the gravity center of the capsule gastroscope is adjusted, a shooting angle is adjusted by rotating the observation mechanism, and a better observation view angle is achieved. Excessive power supply wires do not need to be arranged, the transmission screw can rotate by any number of turns, and the influence of the wires is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a capsule gastroscope and a power supply screw mechanism thereof. Background technique [0002] Capsule gastroscopy is a system that uses software to precisely control the external magnetic field in real time to control the movement of the capsule robot in the stomach, change the posture of the capsule, and take photos of the focus of the lesion according to the required angle, so as to achieve a comprehensive observation of the gastric mucosa and make a diagnosis. The size of the capsule gastroscope itself is relatively small, with a diameter of about 1 cm and a length of about 3 cm. . [0003] Chinese patent CN203107088U discloses a capsule-type gastroscope. This patented technology can fully utilize the functions of smart phones widely used in daily life to realize digestive tract inspection. Patients can swallow the capsule probe by themselves. The multi-...
