Novel endoscopic positioning device for gastrointestinal lesions

Abstract

The invention discloses a novel endoscopic positioning device for gastrointestinal lesions. The device includes a gastrointestinal endoscope head, a moving guide tube fixedly connected to the end partof the gastrointestinal endoscope head and a control unit for controlling the movement of the gastrointestinal endoscope head; and a connecting tube is fixedly connected to the gastrointestinal endoscope head, the connecting tube fixedly sleeves the moving catheter, and three sets of opposite-type photoemitters are fixedly installed on the outer wall of the connecting tube. According to the device, through the detection cooperation of the three sets of opposite-type photoemitters, a detection ring and a micro switch, the detected tumor lesions on the inner wall of a digestive intestine can beeffectively detected and positioned to avoid the phenomenon of deviation in detection positioning, so that the accurate positioning of the detected tumor lesions is realized, the accuracy of detection data is ensured, the detection success rate is improved, the probability of secondary detection and surgery of a patient is effectively reduced, and the work efficiency of a doctor is improved.

Description

technical field [0001] The invention relates to the technical field of medical examination and diagnosis, in particular to a novel endoscopic positioning device for gastrointestinal lesions. Background technique [0002] As we all know, the through-beam photoelectric transmitter is also called a reflective photoelectric switch. It belongs to infrared invisible light products and is a small photoelectric component that can detect changes in the light intensity it receives. In the early stage, it is used to detect whether the object is sensed or not. It is composed of an infrared emitting tube and an infrared receiving tube. Its emission wavelength is 780nm-1mm. The emitter has a calibration lens to focus the light on the Receiver, the receiver out cable connects this unit to a vacuum tube amplifier. It uses objects to block or reflect infrared beams, and detects the presence or absence of objects by synchronous loop gating. The objects are not limited to metals, and can dete...

Problems solved by technology

However, laparoscopic technology, especially non-hands-assisted laparoscopic surgery, has a major defect-the lack of tactile sensation; the operator cannot touch and inspect with his hands like open surgery to determine the location, extent, and relationship with surrounding tissues of the lesion.

[0004] However, the gastrointestinal endoscope in the prior art also lacks effective and accurate monitoring and positioning of lesions, and its endoscopic imaging system also lacks an effective detection device for lesions during the movement in the digestive tract, which easily leads to deviations in detection and positioning.

Inaccurate positioning of the lesion before surgery may mislead the surgeon, increase the chances of tumor spread, implantation metastasis, bleeding, anastomotic leakage and infection, and even lead to miscutting of the lesion in severe cases
