Problems solved by technology

[0004] It only has a water inlet channel. As the operation continues to flush the tissues within the field of vision, more and more water enters the human body. If the water cannot be effectively eliminated, there will be certain risks. For example, the human kidney can only withstand a certain range of water. Renal pressure difference, exceeding this range will cause danger to human life
Although some existing soft endoscopes also drain through the gap between the sheath tube and the soft endoscope, however, there is no special channel for the drainage, which is easy to cause pollution at the doctor's operating end, which is not conducive to the operation

Embodiment 1

[0037] figure 1 Shown is a schematic structural view of a soft endoscope 1 with a water return channel 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.

[0038] to combine figure 1 and figure 2 As shown, the flexible endoscope 1 includes: a tube body 10 with an inner end and an outer end, the inner end is suitable for entering the human body, the outer end is suitable for being placed outside the human body, and the tube body 10 is provided with an instrument channel tube 11. Optical fiber channel tube 12, water inlet channel tube 13, return water channel tube 14 and drawing wire channel tube 15.

[0039] The instrument channel tube 11 is used for entering various surgical instruments, such as scalpels, forceps, etc., and ...

Embodiment 2

[0048] Different from the flexible endoscope 1 with a water return channel in the first embodiment, the second embodiment provides an endoscope with adjustable hardness and softness with a water return channel.

[0049] Such as Figure 4 As shown, the adjustable softness and hardness are realized by a pulling wire 17, and one end of the pulling wire 17 is fixed to the inner end of the tube body 10, that is, relatively fixed to the position of the lens. The opposite end is a free end; specifically, the pulling wire 17 includes at least two metal wires 171 , 172 and a plurality of balls 173 nested on the wire 172 .

[0050] The principle of the endoscope to realize the adjustable soft and hard is:

[0051] Such as Figure 4 As shown, in a normal state, a plurality of spheres 173 are scattered and nested on the wire 172 . In other words, the plurality of spheres 173 are not fixedly connected to the wire 172 , and can slide along the wire 172 to change the distance between adja...

Embodiment 3

[0060] The endoscope with the water return channel provided by this embodiment three is also an endoscope with adjustable hardness and softness, and its structure is roughly the same as that of embodiment two, the difference is that: Figure 7 As shown, there are three wires in the pulling wire 17', that is, a wire 174 is added, and the wire 174 is located on a different side of the sphere 173 from the original wire 171; when the wire 174 is pulled from the free end, the lens can be Rotate in the opposite direction to the pulling wire 171.

[0061] Based on the above principles, the above-mentioned pulling wire may have multiple metal wires to realize the rotation of the lens in multiple directions.

Abstract

The invention provides an endoscope with a return water channel. The endoscope comprises a tube provided with an instrument channel tube, a fiber optic channel tube, an inlet channel tube and a return water channel tube. The return water channel tube for the endoscope allows incoming water to be drained during surgery, excess interior and exterior pressure difference caused by excess water entering human organs can be avoided, and surgical risks can be lowered. In addition, the special return water channel tube allows waste water generated during surgery to be collected, so that pollution of an operating end is prevented. Therefore, the endoscope is easy to operate.

Description

technical field [0001] The invention relates to the field of surgical operation auxiliary instruments, in particular to an endoscope with a water return channel. 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 e...
