Embodiment 1

[0024] Such as figure 1 and figure 2 As shown, the overall assembly diagram of the coil tool is given. First, the upper non-magnetic cylinder 1 is matched with the lower non-magnetic cylinder 2, and then tightened with screws 4. Finally, 12 screws are inserted into the upper and lower non-magnetic cylinders respectively. Root guide post 3 and label number are No. 1-1, ..., 1-12, 2-1, ..., No. 2-12 with this.

[0025] Such as Figure 3a As shown, the upper non-magnetic cylinder is a non-magnetic cylinder with 12 guide post holes made of engineering materials, and the circular hole in the middle is used to pass screws; Figure 3b As shown, the lower non-magnetic cylinder is a non-magnetic cylinder with 12 guide post holes made of engineering materials, and the middle is a threaded hole for tightening the upper and lower non-magnetic cylinders.

[0026] Such as figure 2 As shown, this embodiment uses an odd number of wires for winding, and the most classic three wires are u...

Abstract

The invention discloses a manufacturing method of an oval wire wrapping coil used for a capsule endoscope. According to the manufacturing method of the oval wire wrapping coil used for the capsule endoscope, a non-magnetic round barrel is adopted for winding of the oval coil, two sets of radial fixing columns are arranged outside the non-magnetic round barrel, an annular magnetic core is adopted, and the coil is wound on the magnetic core in an oval mode. The coil manufactured with the method is high in excitation area uniformity and the error due to the fact that no effective tool is available for manufacturing a coil is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a preparation method for an elliptical wound coil used in a capsule endoscope. Background technique [0002] In recent years, with the rapid development of electronic technology, the size and energy consumption of various integrated circuits have been greatly reduced, making the emergence of miniature wireless endoscopes possible. But limited to the volume of the capsule, the battery must be very small, resulting in insufficient battery capacity, so the microcapsule endoscope can only work for 6-8 hours at most, and can only shoot a few frames of images per second. Wireless energy supply is the research hotspot of energy supply at the present stage. Using wireless energy transmission to power capsule endoscopes solves the problem of short working hours of capsule endoscopes, and enables capsule endoscopes to conduct a comprehensive inspection of the human digestive tract....
