Description

Dysmorphism stereoplasm bronchoscope

Technical Field

The utility model relates to the field of medical equipment, concretely relates to dysmorphism stereoplasm bronchoscope.

Background

The hard bronchoscope (the hard visual bronchoscope) is used as an examination and treatment tool, a safe and effective method is provided for clinical observation of glottis and trachea, and an experienced operator can complete examination operation in a natural body position of a patient by using the fiber bronchoscope and the hard bronchoscope;

the current hard bronchoscope used clinically takes visual Ni as a representative, has consistent structural characteristics and has the main defects that:

1. the lens axis of the lens at the objective lens end is coaxial with the tangent extension line of the lens body cavity, and the lens and the tail end of the lens body are in the same plane and are easily covered and shielded by soft tissues;

2. the curvature of the lens bodies at the eyepiece end and the objective end is too small, and the internal included angle between the lens bodies at the eyepiece end and the objective end is more than 90 degrees, so that the tracheal catheter of the coat is difficult to fix;

regarding the 1 st defect, because the lens is located at the end of the lens body and is in the same plane with the lens body, and the diameter of the lens body is thin, the lens body is easily shielded by the soft tongue body and the tissues in the oral cavity in a close contact manner when being placed in the oral cavity, the lens is shielded, the gap is lost, and no enough gap exists, the imaging focal length does not exist, so that the lens cannot be imaged clearly;

regarding the 2 nd defect, because the angle between the eyepiece end and the objective end of the endoscope body is an obtuse angle, the fitting with the actual anatomical radian is poor, the adjustment of the objective end to the glottis of the throat part is difficult to a certain extent when the endoscope is placed in the throat part, and then when the visual guide tracheal intubation is made by visual aid, the tracheal catheter needs to be sleeved outside the bronchoscope; however, because the internal included angle of the endoscope body is larger than 90 degrees and forms an obtuse angle, the radian is too large, the friction force between the tracheal catheter sleeved outside the endoscope body and the endoscope body is sometimes insufficient to fix the catheter, when the endoscope body sleeved with the tracheal catheter is placed in an oral cavity or a nasal cavity, the friction resistance of tissues in the oral cavity and the nasal cavity to the tracheal catheter sleeved outside is often larger than the friction resistance between the tracheal catheter and the endoscope body in the tracheal catheter, so that the lens end in the endoscope body is easy to slip off the tail end of the tracheal catheter, the lens end loses the brim-like support protection of the tail end of the tracheal catheter, and the lens is easy to be shielded by tissues and difficult to clearly image, thereby the examination operation becomes difficult;

in the current new coronary pneumonia epidemic situation, many critical patients need to use a hard bronchoscope to check, but the existing hard bronchoscope is poorer in conformity with the actual anatomical radian, the lens is easy to be shielded by tissue contact, the operation can be influenced, the operation time is prolonged, meanwhile, repeated long-time operation stimulation of the throat can cause discomfort of the patient and cause the patient to choke, the respiratory tract endocrine of the patient can be sprayed to the outside due to the choke, and the secretion of the new coronary pneumonia patient is extremely infectious, so that the risk of pollution to an operator and the surrounding environment is extremely easy to cause. Therefore, the hard bronchoscope is made to be matched with the actual anatomical radian, more importantly, the lens is not easy to be shielded to influence observation, the continuous and clear visual field is kept, the whole operation process is simple and effective, the operation can be completed quickly, and the design of the technical scheme is original.

when the trachea cannula is guided by the aid of the hard bronchoscope, the trachea catheter is firstly sleeved outside the hard bronchoscope body 101, the tail end of the trachea catheter slightly protrudes out of the tail end of the lens 103, due to the fact that the scope body 101 has enough bending degree, enough friction force exists between the sleeved trachea catheter and the scope body 101, the relative position of the tracheal catheter and the scope body is fixed and is not prone to falling off in the process of placement, the placement and observation method is as above, after glottis is clearly displayed, the trachea catheter is then sent into the trachea along the glottis crack for more than 10mm, the handle 109 is held by hand to be fixed, the trachea catheter is pushed into the trachea slightly with force, the trachea cannula guided by the hard bronchoscope is fixed and sent to an appropriate depth, and the trachea.

To sum up, the special-shaped hard bronchoscope of the utility model can make the electronic imaging system with the light source into the video device matched with the video device placing channel tube, and comprises the electronic camera lens and the display, the electronic camera lens and the scope body are made into a whole, and the special-shaped hard bronchoscope can be sterilized and reused;

the shape of the object lens end is increased to be more fit with the anatomical radian of the upper respiratory tract, so that the object lens end can be more easily placed and adjusted to the supraglottic area of the throat part, and the sleeved tracheal catheter can be well fixed and is not easy to slip; after the objective end of the endoscope body is placed in the oral cavity and the nasal cavity, the inner included angle formed by the placing part of the endoscope body in the upper respiratory tract and the upper respiratory tract is less than or equal to 90 degrees, the anatomical angles of the oral pharynx axis and the tracheal acoustic portal axis can be better fitted, the head position does not need to be specially adjusted, the shape is more in line with the natural anatomical radian, and the endoscope body is convenient to place to reach a target position;

the shape of the natural anatomical radian of the actual oropharynx and larynx is approached to the maximum extent, and most importantly, the thin lens body is guaranteed to the maximum extent, and when the lens is placed into the upper respiratory tract, a sufficiently fixed spacing distance can be guaranteed between the lens and encountered soft tissues in the oral cavity in the placing process by means of the special brim-shaped design protruding from the front end of the objective lens, the distance is the depth of field which guarantees that the lens can clearly image, and the lens cannot be easily directly contacted and shielded by the tongue body and soft tissues in the oral cavity to cause imaging failure;

when the endoscope is used for guiding the tracheal cannula, because the internal included angle is less than or equal to 90 degrees, the endoscope body and the tracheal catheter of the outer sleeve have enough frictional resistance, so that the endoscope body can not slip off the tracheal catheter in the process of placement;

the operator does not need to face the oral cavity of the patient in a close distance, and the tracheal intubation is simply, effectively and quickly completed, which plays an important role in reducing direct contact contamination of the operator by the patient, especially an infectious patient.

The above description has been made of specific embodiments of the present invention. It is to be understood that the invention is not limited to the particular embodiments described above, and that devices and structures not described in detail are understood to be implemented in a manner common in the art; various changes or modifications may be made by those skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
