Problems solved by technology

The lighting optical fiber of the existing endoscope is fixed on the endoscope, and the cost of the general optical fiber is relatively expensive, and the damage of other low-cost parts of the endoscope will cause the optical fiber to lose its use value, which leads to higher operation costs , not conducive to the operation

Embodiment 1

[0038] figure 1 Shown is a schematic structural view of the flexible endoscope 1 provided in Embodiment 1 of the present invention, figure 2 shown along figure 1 The cross-sectional view of the line A-A in the middle. The flexible endoscope 1 can be a ureteroscope, a pyeloscope, a cystoscope, a gastroscope, a colonoscope, a bronchoscope, a choledochoscope or a hysteroscope, etc.

[0039] combine figure 1 and figure 2 As shown, the flexible endoscope 1 includes: a tube body 10 having an instrument channel tube 11 , an illumination channel tube 12 , a water inlet channel tube 13 and a drawing wire channel 14 .

[0040] The instrument channel tube 11 is used for entering various surgical instruments, such as scalpels, forceps, etc., and can also be an optical fiber channel for surgical operations by laser. The lighting channel pipe 12 is adapted to accommodate lighting optical fibers, and the lighting source is an existing light source, such as a Xenon lamp. The illuminat...

Embodiment 2

[0047] Different from the flexible endoscope 1 in the first embodiment, the second embodiment provides an endoscope 2 with adjustable softness and hardness, such as Figure 4 shown. Figure 5 shown along Figure 4 Sectional view of the line B-B in the center.

[0048] combine Figure 4 and Figure 5 As shown, the flexible and hard adjustable endoscope 2 includes: a tube body 20 having an instrument channel tube 11 , an illumination channel tube 12 , a water inlet channel tube 13 , a drawing wire channel 14 and a water return channel tube 17 .

[0049] The return water channel pipe 17 is used for the discharge of waste water, and it includes two ends, one of which is flush with or slightly shorter than the lens of the flexible and hard adjustable endoscope 2 (that is, to ensure that the field of view of the lens is not affected), and this end is used for entering The human body is also called the inner end, and the other end opposite to the inner end is the outer end, which...

Abstract

The invention provides a detachable endoscope. The detachable endoscope comprises a tube body which at least comprises an instrument passage tube, a water inlet passage tube and an illumination passage tube, wherein the illumination passage tube is suitable for accommodating an illuminating optic fiber which is in detachable connection with the tube body. By detachably connecting the illuminating optic fiber with the tube body, after other low-cost parts of the endoscope are damaged, the optic fiber can be taken out to match with other parts in a new endoscope, so that operation cost is reduced, and many operations are facilitated.

Description

technical field [0001] The invention relates to the field of surgical operation auxiliary instruments, in particular to a detachable endoscope. Background technique [0002] Endoscopes, such as ureteroscopes, are widely used in surgery and are suitable for insertion into the human body for some auxiliary treatments. Existing ureteroscopes include hard endoscopes and soft endoscopes, and hard endoscopes can only perform operations with relatively definite locations of lesions because the lens cannot be rotated. For some operations where the location of the lesion is not clear, for example, after the lens enters the renal pelvis, the ureteroscope needs to be constantly adjusted to enter different renal calyces to find the lesion for surgery. However, due to the soft material of this kind of soft endoscope, when entering the human body, it is necessary to use a hard material (usually a sheath) to establish a channel in the human body, and then send the soft endoscope into the ...
