Description

Biobattery-Based Intestinal Robot

technical field

The invention relates to an intestinal robot based on a biological battery, in particular to an intestinal robot driven by electric energy generated by biological and organic substances in the intestinal tract.

Background technique

As a part of minimally invasive treatment, endoscopy has been used in many fields such as disease inspection, and has attracted extensive attention from researchers due to its non-invasiveness and effectiveness. Endoscopes currently used for intestinal inspection are still rigid or semi-rigid, and the distal movement is controlled by a rope and an external knob. Because of the folds, depressions, and curvature of the intestinal wall, it is difficult to insert an endoscope deep into the intestine without damaging the intestinal tissue. For this reason, people have proposed and developed a variety of tiny intestinal robotic endoscope systems. However, these traditional intestinal robots all adopt external batteries, and the working hours of these external batteries are short, and the chemical substances of some batteries are harmful to the human body.

Contents of the invention

The purpose of the present invention is to provide a bio-battery-based intestinal robot that can generate electricity by using its own substances in the human intestinal tract and drive itself along the intestinal tract.

The intestinal robot based on the bio-battery of the present invention includes a front disc, a rear disc, and a middle disc. The disk is divided into three connecting rods at 120°. Each connecting rod is composed of two sections of rods hinged. The two ends of the connecting rod are respectively hinged with the disk. A shape-memory alloy spring, a second shape-memory alloy spring is fastened at the center of the middle disc and the center of the back-end disc, a sealed control circuit is fixed on the end face of the front disc, and a micro camera is fixed on the end face of the control circuit , the first and second shape memory alloy springs and the micro-camera are respectively connected to the output end of the control circuit, a bio-battery is fixed on the end face of the rear disc, and the bio-battery is connected to the input end of the control circuit.

The above-mentioned biobattery is a battery that uses bacteria in the intestine to generate electricity. Said control circuit can adopt the DC voltage pulse circuit which converts the voltage generated by the bio-battery into 2V-5.5V, and provides the corresponding pulse current according to the voltage requirements of the shape memory alloy spring and the micro-camera.

When working, the bio-battery uses the bacteria and organic matter in the intestinal tract to generate electric energy to heat the shape memory alloy spring. Under the control of the pulse current of the control circuit, the current first passes through the first shape memory alloy spring, and the first shape memory alloy spring is heated. Shorten, and the disks at the ends of this spring move closer together, causing the connecting rod to arch outward against the gut, while the second shape memory alloy spring remains in place since no current is passing through it. Then the current passes through the second shape memory alloy spring, the second shape memory alloy spring is heated and shortened, and the connecting rod arches outward to withstand the intestinal tract. Changing back to the original horizontal position made the distance between the two discs longer, making the intestinal robot one step forward. Such a cyclical movement makes the intestinal robot move forward continuously.

The beneficial effects of the invention are: changing the power supply mode of the traditional intestinal robot, using the self-material in the intestinal tract to generate electricity to realize the work of the intestinal robot, which has the advantages of energy saving, safety and the like. The robot has good movement ability, can carry a miniature camera to record the situation in the intestine, and can be used as a medical intestinal inspection endoscope.
