Description

Flexible electronic nephroscope with bendable tail end

Technical Field

The invention relates to the technical field of electronic nephroscopes, in particular to a flexible electronic nephroscope with a bendable tail end.

Background

With the development of scientific technology, instruments used in surgical operations have changed day by day. The improvement of the surgical instrument can lead a doctor to better complete the operation, lead the operation time to be shorter and lead the trauma to the patient to be smaller. Urolithiasis is one of the common conditions of urology surgery and often requires treatment by surgery. At present, percutaneous nephrolithotomy is a standard treatment mode for kidney stones with the diameter of more than 2 cm, and almost all kidney stones with the diameter of more than 2 cm can be treated. However, antler stones (parallel calyx stones) are still a difficulty in percutaneous nephrolithotomy, and are limited by the anatomical morphology of a kidney assembly system, when antler stones (parallel calyx stones) are treated, a plurality of percutaneous renal puncture channels are often required to be established under the existing mainstream instruments, so that a large wound is brought to a patient, and the difficulty and the risk of the operation are increased. In addition, with the continuous progress of the technology, the puncture channel of the percutaneous nephrolithotomy becomes smaller and smaller, and the higher requirement is put on the design of the instrument while the trauma is reduced. Chinese patents are disclosed in the prior art documents: the 'electronic pyeloscope (CN 203369935U) with a bendable head end' comprises an operating handle, a scope tube and a light guide structure. The endoscope tube comprises an endoscope tube, a bending part and a tip part which are connected in sequence, and the bending part is controlled by a bending handle positioned on the operating handle. An instrument channel, a light guide channel and an imaging channel which are parallel to each other are arranged in the endoscope tube, and the instrument channel is larger than the light guide channel and the imaging channel. Another Chinese patent: "a percutaneous nephroscope (CN 207220791U) with bendable distal end" includes a hard distal end portion on the endoscope main body side and a bendable soft distal end portion. However, the joint of the hard part and the bent part of the combined bendable nephroscope structure at the tail (head) end is easy to be damaged, so that the combined bendable nephroscope structure cannot be completely suitable for complex anatomical structures of renal pelvis and calyx, particularly, the observation and lithotripsy effects on stones in parallel calyx beside a channel are poor, the tearing bleeding of a puncture calyx is caused by an overlarge swinging angle of the hard part of an endoscope main body, and the combined bendable nephroscope structure is not suitable for micro-channel percutaneous nephrolithotripsy lithotomy.
