Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, and particularly to a front-soft-and-rear-hard renaloscope insertion part for an endoscope. Background Art

[0002] An endoscope is a medical device used for examination and treatment inside the human body. It enters the body through the body's natural cavity or small incision, enabling doctors to observe and treat internal organs without performing major surgeries. The development of endoscope technology has greatly improved the accuracy and safety of medical diagnosis and treatment. The working principle of an endoscope is mainly based on optical and electronic technologies. Traditional optical endoscopes transmit internal images to an external eyepiece or camera through a series of high-precision optical lenses. Doctors can directly observe through the eyepiece or see the magnified image on a display screen. Modern electronic endoscopes are equipped with a miniature camera and a lighting system at the end inserted into the human body. The image captured by the camera is transmitted through a cable to an external image processing system and finally displayed on a monitor. This design not only improves the clarity of the image but also makes the operation more flexible and convenient.

[0003] Existing endoscope technologies mainly include two types: rigid endoscopes and flexible endoscopes. Rigid endoscopes have high rigidity and are suitable for operations under direct vision, but their ability to enter complex structures is limited. Flexible endoscopes have better flexibility and can bend into narrow or curved channels, but their operation complexity is high and they require an additional guide wire for guidance. Currently, due to their rigid structure, rigid endoscopes cannot enter complex parts such as the renal pelvis, which limits their application scope. Although flexible endoscopes have a certain degree of flexibility, when in use, a guide wire needs to be inserted through a rigid endoscope first, and then subsequent operations can be carried out. This not only increases the complexity of the surgery but also increases the types and costs of instruments, bringing inconvenience to clinical use. Summary of the Invention

[0004] In view of the above problems of the existing technology that due to their rigid structure, rigid endoscopes cannot enter complex parts such as the renal pelvis, which limits their application scope, and although flexible endoscopes have a certain degree of flexibility, when in use, a guide wire needs to be inserted through a rigid endoscope first, and then subsequent operations can be carried out. This not only increases the complexity of the surgery but also increases the types and costs of instruments, bringing inconvenience to clinical use, the present invention is proposed.

[0005] Therefore, the object of the present invention is to provide a front-soft-and-rear-hard renaloscope insertion part for an endoscope, and its purpose is to: design the insertion part into a front-soft-and-rear-hard structure, which not only retains the rigidity of the rigid endoscope but also has the flexibility of the flexible endoscope, enabling the insertion part to enter the bladder ureter like a rigid endoscope without a lens, and also enter the renal pelvis like a flexible endoscope, greatly improving the applicability of the insertion part.

Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Refer to Figures 1-7, which is an embodiment of the present invention, provides a front-soft and rear-hard renaloscope insertion part for an endoscope. This front-soft and rear-hard renaloscope insertion part for an endoscope includes an endoscope insertion part 1, and also includes a rigid part 2 provided at one end of the surface of the endoscope insertion part 1, an active bending section 3 provided at the other end of the surface of the endoscope insertion part 1, a passive bending section 4 provided at one end of the surface of the endoscope insertion part 1 close to the active bending section 3, and a front end cap 5 provided at one end of the endoscope insertion part 1 close to the active bending section 3.

The middle end of the limiting plate 15 is lower than the two end parts, and the two end parts are arc-shaped and bulged. The limiting plate 15 is used to assist in restricting the wires 7 and the instrument pipelines 6 in the inner cavity of the endoscope insertion part 1, avoiding the winding of the wires 7 and the instrument pipelines 6 in the endoscope insertion part 1.

[0034] On one end of the surface of the endoscope insertion part 1 far from the front end cap 5, two groups of mounting slots 18 are provided, and the mounting slots 18 are symmetrically arranged at one end of the surface of the endoscope insertion part 1, facilitating the installation operation.

[0035] During use, by the mutual cooperation of the rigid part 2, the active bending section 3 and the passive bending section 4, the endoscope insertion part is designed to be soft at the front and hard at the back.

At the same time, this design reduces the types of instruments required during the operation, reduces the cost, simplifies the operation steps, reduces the pain of the patient and the operation time. Furthermore, it not only improves the accuracy and success rate of the operation, but also reduces the complexity and cost of the operation, which is a great progress for both patients and doctors.
