Description

Endoscope with automatic resilience function

Technical Field

The utility model belongs to the field of endoscopes, and particularly relates to an endoscope with an automatic rebounding function.

Background

The electronic endoscope is a medical electronic optical instrument which can be inserted into the body cavity and internal organ cavity of human body to make direct observation, diagnosis and treatment by integrating high-precision techniques of light collection, machine and electricity, etc. The electronic endoscope has the working principle that picture information obtained from an objective lens is converted into electronic information, and the electronic information is converted through a circuit and finally displayed on a display screen. The electronic endoscope mainly comprises a tip bending part, an insertion part, an operation part and an electric joint part. The tip bending part is the foremost end of the endoscope and is composed of a water/air feeding nozzle, a light guide beam, an objective lens, a forceps pipeline outlet, a bending rubber and the like. The outside of the inserting part is a scale sheath, and the inside of the inserting part is wrapped with a light guide bundle, an image guide bundle, a water/air supply pipe, a clamp pipeline and a drum wheel steel wire. The operation part is a part which is operated by a doctor in a hand-held way during examination and treatment, and mainly comprises an angle control rotor, a lock, a function button, a suction piston, a water/air feeding piston, a forceps pipeline inlet and the like. The electric joint part is a part of the electronic endoscope for connecting the cold light source and the image processing system and consists of an electric joint, a light guide joint, a water/air supply joint and a suction joint. The most frequently operated parts in the diagnosis and treatment activities are the operation parts, which comprise an air supply/water supply button, a suction button, a movable picking channel, an angle button and the like. The second is a lens body which is a flexible insertion tube made of a steel wire mesh tube and a snake-shaped steel tube, and a guide beam, a light guide beam, a biopsy/suction channel, a gas injection/water injection pipeline, a steel wire for controlling the angle and the like are accommodated in the tube diameter smaller than 1 cm. A polyurethane plastic tube is wrapped, which has sealing and corrosion protection functions to prevent water and gastric juices from entering and corroding. When the two frequently-working parts are damaged, a professional must be required to repair the two frequently-working parts by using special tools and special accessories, and the cost is high and the time is long. Therefore, the correct operation and the careful maintenance are of great significance to prevent and reduce the occurrence of the faults of the electronic endoscope and prolong the service life of the electronic endoscope. When the bending device is used, the motion state of the bending part is usually adjusted by controlling the operation part, and the bending part cannot be automatically reset during adjustment, so that the operation and adjustment of the operation part are needed, and the complexity of a doctor during operation is increased.
