An endoscope positioning device for digestive tract lesions

Abstract

The invention discloses an endoscope positioning device for digestive tract lesions, comprising a digestive tract lens, a moving catheter fixedly connected to the end of the digestive tract lens, and a control unit for controlling the movement of the digestive tract lens. The digestive tract lens is fixedly connected on the digestive tract There is a connecting pipe, and the connecting pipe is fixedly sleeved on the moving guide pipe, and three groups of opposite-radiation photoelectric transmitters are fixedly installed on the outer wall of the connecting pipe. The invention can effectively detect and locate the detected tumor lesions on the inner wall of the digestive tract through the detection cooperation of three sets of photoelectric emitters, the detection ring and the micro switch, and avoid the phenomenon of deviation in detection and positioning. The precise positioning of the detected tumor lesions is realized, the accuracy of the detection data is ensured, the detection success rate is improved, the probability that the patient needs to perform secondary detection and surgery is effectively reduced, and the work efficiency of the doctor is improved.

Description

technical field [0001] The invention relates to the technical field of medical examination and diagnosis, in particular to an endoscope positioning device for digestive tract lesions. Background technique [0002] As we all know, the opposite photoelectric transmitter is also called a reflective photoelectric switch, which belongs to the infrared invisible light product and is a small photoelectric component, which can detect the change of 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 transmitter has a calibration lens to focus the light towards The receiver, the receiver out cable connects the set to a vacuum tube amplifier. It uses objects to shield or reflect infrared beams, and is gated by a synchronous circuit to detect the presence or absence of objects. The objects are not limited to met...

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
