Medical fiberscope protection equipment, medical fiberscope protection system and fiberscope system

Technical Field

The utility model relates to a medical fiberoptic scope protection instrument especially relates to a medical fiberoptic scope protection equipment, medical fiberoptic scope protection system and fiberoptic scope system.

Background

In many invasive medical operations, a tube-like instrument needs to be placed in a patient body to establish an operation channel, so that the medical instrument can perform operation at a position corresponding to a focus and the operation safety can be improved. The position of the head end of the tube instrument is determined according to the position of a focus and the type of an operation, and the accuracy of the position directly influences the quality of the operation. During some interventional medical procedures, doctors also need to obtain real-time image information of the surgical site to successfully complete the procedure and improve the safety of the procedure.

The endoscope has an imaging function, and currently, the visualization technology of the endoscope is generally used for positioning the tubular instruments and acquiring real-time image information of a surgical site. The fiber mirror is used as one of endoscopes, has better flexibility and convenience, and is a better choice for positioning tube instruments and acquiring real-time image information of a surgical site. The fiber mirror comprises a flexible insertion part, the head end of the insertion part is provided with a lens for imaging, and the head end of the insertion part can be inserted into the body of a patient.

The insertion part of the fiber mirror has the characteristics of slender, soft and easy bending, when a tube instrument is implanted in a clinical operation, the instrument is usually required to be swung in real time according to the operation body position to adjust the operation intervention angle so as to reach the expected focus position, and the slender, soft and long fiber mirror inevitably moves or bends to a certain extent in the process, so that the insertion part of the fiber mirror cannot be effectively fixed, the lens at the head end part is easy to axially retract or protrude from the head end of a catheter, the imaging visual field is influenced, the visual field angle is deviated, and the acquired image information is inaccurate; in order to solve the problems, the insertion part is fixed with the tube instruments by using the fiberscope protection device, but the tube instruments on the market are various in types and different in length, and the existing fiberscope protection device can only be matched with the tube instruments with the specific length specifications, so that the fiberscope protection device cannot be compatible with the tube instruments different in length on the market.

The length of the inserting part of the optical fiber scope is larger than that of the pipe instrument used in a matched mode, so that the optical fiber scope is provided with a section of inserting part exposed at the tail end of the pipe instrument when the optical fiber scope is used in a combined mode, the slender inserting part of the optical fiber scope is easily broken or damaged under the condition, and the imaging effect is further influenced.

Taking urinary calculus surgery as an example, two important means for treating kidney stones with diameters larger than 2cm are percutaneous nephrolithotomy and ureteroscope lithotripsy, and the safety of the two operations can be improved by means of a fiber optic scope. Among them in the percutaneous nephroscope lithotripsy, accurate, establish percutaneous nephroscope operation passageway safely is the key link, and superfine fiber mirror can establish the operation passageway more safely, accurately, fast, realizes visual puncture, reduces the probability of bleeding, damage. Ureteroscope access sheaths are generally used as tube instruments in ureteroscope lithotripsy to avoid operation complications, such as damages, stenosis, perforation and the like of the urethra and the ureter, caused by frequently entering and exiting medical instruments to patients during operation; the key step of ureteroscope lithotripsy is to put the ureteroscope channel sheath into place, and the whole monitoring sheath placing process can be realized by using the ultra-fine fiber mirror to be matched with the ureteroscope channel sheath in the step, so that the ureteroscope channel sheath can smoothly pass through the urethra and safely reach the upper section of the ureter, and a ureteroscope lithotripsy operation channel is effectively established. However, in percutaneous nephrolithotomy and ureteroscope lithotomy, the defects that the fiberscope protection device cannot be compatible with the tube instruments with different length specifications exist, and the part of the insertion part externally arranged on the tube instrument is easy to break or damage exist.

The fiberscope comprises an insertion part 400 and an eyepiece part 500, wherein the insertion part 400 is used for acquiring image information and transmitting the image information to the eyepiece part 500; the head end of the medical fiberscope protection system 600 is connected with the pipe-like instrument 100 and the insertion part 400, and the tail end of the medical fiberscope protection system 600 is connected with the eyepiece part 500.

Fig. 6 and 7 illustrate an application scenario when the medical fiberscope protection system 600 is matched with different tube instruments 100, where the tube instrument 100 in fig. 6 is longer, the insertion portion 400 exposed outside the tube instrument 100 is shorter, the tube instrument 100 in fig. 7 is shorter, and the insertion portion 400 exposed outside the tube instrument 100 is longer, and it can be seen visually from a comparison between fig. 6 and 7 that the medical fiberscope protection device 300 is in different length states, of course, the length of the fiberscope protection device 200 in fig. 6 and 7 is different, only that the length is not visually shown in the figures.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
