Description

Laryngoscope capable of adjusting peeping angle Technical Field The invention relates to the technical field of laryngoscopes, in particular to a laryngoscope capable of adjusting a peeping angle. Background The principle of laryngoscopes is to use optical reflection or electronic imaging techniques, using optical magnification systems or video imaging techniques, to enable a physician to directly observe and assess the laryngeal condition of a patient, thereby helping to diagnose and treat laryngeal disorders. Laryngoscopy can be classified into indirect laryngoscopy, direct laryngoscopy, fibrous laryngoscopy, electronic laryngoscopy, etc., depending on the particular method, with indirect laryngoscopy generally being most commonly used. The electronic laryngoscope combines the electronic technology and the optical principle, and has the advantages of clear image, flexible operation and the like. The electronic laryngoscope is generally composed of a lens, a camera, a display and the like, wherein the camera at the front end of the lens can transmit the image of the throat to the display in real time, and a doctor can clearly observe the pathological change condition of the throat through the display. Compared with the traditional indirect laryngoscope, the electronic laryngoscope has higher resolution and larger visual field range, and can find some tiny lesions. Moreover, the electronic laryngoscope can take pictures, record videos and other operations, so that doctors can record and analyze the illness state conveniently. Most of the existing laryngoscopes are fixed in peeping angle, all parts of the throat are difficult to comprehensively and clearly observe, so that medical staff can not accurately adjust the peeping angle of the detection camera when the throat is inspected if the medical staff wants to adjust the angle to implement comprehensive and accurate inspection operation, a hose extending into the throat of a patient is required to be manually adjusted to adjust the inspection angle of the laryngoscope, but in the manual adjustment process, the soft rod of the laryngoscope is easily affected by the operation environment, the problems of clamping and deviation and the like are easy to occur in the adjustment process, and the peeping angle of the detection camera cannot be accurately adjusted, so that the smoothness and accuracy of operation are affected. Disclosure of Invention In view of the above problems, the present application provides a laryngoscope with adjustable peeping angle. In order to achieve the purpose, the laryngoscope with the adjustable peeping angle comprises a hollow hose, a traction soft rod for traction of movement of the hose, a detection camera extending into the throat of a patient and a butt joint rod positioned outside the oral cavity of the patient, wherein two ends of the hose are respectively provided with a first sleeving part and a second sleeving part, and the detection camera and the butt joint rod are respectively connected with the first sleeving part and the second sleeving part in a socket joint manner. The utility model discloses a hose, including hose, soft rod, sleeve, guide roller, spacing roller, guide roller, locating sleeve, soft rod end branch forms two spacing turn-ups portions after being close to first portion one end that cup joints of hose is fixed with two symmetry distributions, and two spacing turn-ups portions are fixed mutually through the hoop with soft rod that pulls after bypassing two locating sleeves respectively, the butt joint pole outside is equipped with guide roller and spacing roller, and soft rod that pulls is kept away from the one end that the locating sleeve wears out from hose and is close to second portion one end that cup joints the back, passes in the relative space of guide roller and spacing roller, runs through it along the radial route of butt joint pole again. Furthermore, the hoop frame is installed at the guide roller center axis position through the pivot, the hoop frame both sides all extend towards guide roller edge and form the oblique frame that stretches, spacing gyro wheel is installed in the oblique frame inboard through the pivot, and guide roller and spacing gyro wheel's clearance forms the space that can hold the soft pole of traction. Furthermore, the hoop frame is sleeved on the butt joint rod and is fixed with the butt joint rod through a detachable positioning bolt. Further, the soft traction rod is located one end of the outer side of the butt joint rod and is sleeved with a lifting handle, two channels are formed in the lifting handle and are distributed in a diagonally staggered mode, movable locking rods are arranged in the two channels, two through holes which are distributed from top to bottom are formed in the inner side of the soft traction rod, and the two locking rods penetrate through the through holes. Further, the one end that the locking lever is located the promotion handle outside
