Description
Technical Field
The utility model relates to an endoscope technical field, concretely relates to sensor and endoscope for endoscope.
Background
Endoscopes have gained widespread acceptance in the medical community because they provide a means for performing surgery with minimal trauma to the patient while allowing the physician to view the internal anatomy of the patient. Over the years, many endoscopes have been developed and classified according to specific applications, such as cystoscopes, colonoscopes, laparoscopes, upper gastrointestinal endoscopes, and the like. The endoscope may be inserted into a natural opening in the body, or through an incision in the skin.
Endoscopes are typically elongated tubular shafts, rigid or flexible, having a camera or fiber optic lens assembly at their distal end. The shaft is connected to a handle, which sometimes includes an eyepiece for direct viewing. Viewing via an external screen is also generally possible. Various surgical tools may be inserted through the working channel in the endoscope for performing different surgical procedures.
Various endoscopes are known which employ an optical head in a front end insertion portion thereof for observing the inside of a body cavity or a lumen (lumen) such as the lower digestive tract. Typically, such an optical head comprises at least an illumination device for illuminating the object, an objective system and a sensor array. How the sensor for an endoscope is designed is a key to accurately detect the bending and curved path of the insertion tube in the body.
SUMMERY OF THE UTILITY MODEL
The utility model provides a sensor for endoscope, it can detect the crookedness and the crooked route of insert tube in vivo more accurately, sensitively, is provided with:
a light source;
a light-conducting device;
two groups of phosphors, wherein one group of phosphors and the other group of phosphors are arranged in the light conduction device in a mode of axial displacement and circumferential orthogonality, the number of each group of phosphors is two, and the two groups of phosphors are arranged at intervals along the same axial direction;
a light reflection means for reflecting the transmitted light to the light detection means;
and a light calculation device in which four detection portions are arranged corresponding to the fluorescent bodies, and which independently detects the received detection light and calculates the bending degree and the bending path of the endoscope insertion tube by calculation.
Further, the four phosphors absorb light of the same wavelength and emit light of different wavelengths.
Further, the light-conducting device comprises, from inside to outside, a core through which light passes, a cladding preventing light from leaking out, and a protective sheath.
Further, a light branching portion is provided before the light conduction device.
