[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] Embodiment 1:

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A ureteroscope guide sheath kit includes: a sheath tube 1, a dilating tube 101, and a sheath seat 102, wherein the dilating tube 101 and the sheath seat 102 are respectively fixedly connected to the two ends of the sheath tube 1 and are communicated with the sheath tube 1; a connecting tube 103 is arranged on the sheath seat 102 and is communicated with the sheath tube 1 through the sheath seat 102; two hand-held rings 3 are symmetrically fixedly connected to the sheath tube 1, wherein an annular groove 302 is opened on the inner wall of the hand-held ring 3, and a wrapped airbag 301 is arranged around the annular groove 302.

[0025] The expansion tube 101 is arranged in a conical shape.

[0026] Both the sheath tube 1 and the dilation tube 101 are hard tubes.

[0027] In urological surgery, when it is necessary to establish a channel for an endoscope and other instruments to enter the urinary tract, the medical staff can hold the sheath seat 102 and then extend the sheath 1 into the patient's urethra through the dilation tube 101. (It should be noted that since the urethra is in a closed state when not urinating, the patient's urethra can be stretched open by the conical dilation tube 101 to facilitate the sheath 1 to smoothly extend into the patient's urethra). After the guide sheath is inserted into place, the medical staff can insert the endoscope and other instruments through the guide sheath into the urethra for surgical operations.

[0028] In order to facilitate the medical staff to smoothly insert the guide sheath into the patient's urethra, the medical staff can also insert their fingers into the hand-held ring 3, and by holding the hand-held ring 3, smoothly insert the guide sheath into the patient's urethra. At this time, the medical staff's fingers are wrapped by the wrapping air bag 301 in the hand-held ring 3, thereby increasing the stability of the medical staff holding the sheath seat 102, making it easier for the medical staff to smoothly insert the guide sheath into the patient's urethra. Therefore, it not only reduces the risk of damage to the endoscope and stone removal instruments due to the unstable hand-holding of the guide sheath during the operation, but also reduces the probability of accidental injury to the patient's organs. At the same time, because the wrapping air bag 301 is elastic, the comfort of the medical staff when holding the hand-held ring 3 can be increased.

[0029] Embodiment 2:

[0030] Reference Figure 1 , Figure 2 A ureteroscope guide sheath kit is basically the same as Example 1, and further, the outer wall of the sheath tube 1 is fixedly connected with a protective sleeve 104; the protective sleeve 104 is a latex sleeve.

[0031] When the sheath tube 1 is inserted into the patient's urethra, since the protective sleeve 104 on the outer wall of the sheath tube 1 is made of a latex sleeve with good softness, the protective sleeve 104 will be deformed under the compression of the urethra, thereby increasing the softness of the guide sheath and improving the patient's comfort.

[0032] Embodiment 3:

[0033] Reference Figure 2 , a ureteroscope guide sheath kit, which is basically the same as Example 1, and further, the end of the dilation tube 101 away from the sheath tube 1 is arranged in an arc shape.

[0034] When the medical staff holds the sheath seat 102 and inserts the sheath 1 into the patient's urethra through the conically arranged expansion tube 101, the expansion tube 101 is arranged in an arc shape at one end away from the sheath 1, so that the expansion tube 101 can be prevented from scratching the inner wall of the patient's urethra when it is inserted into the patient's urethra.

[0035] Embodiment 4:

[0036] Reference Figure 1 , Figure 2 A ureteroscope guide sheath kit is basically the same as Example 1. Furthermore, a protective sleeve 2 is sleeved on the dilation tube 101, and a non-slip layer is provided on the side of the protective sleeve 2 that fits the protective sleeve 104.

[0037] By sleeved the protective sleeve 2 on the outer wall of the expansion tube 101, the expansion tube 101 can be protected to prevent the expansion tube 101 from being squeezed or bumped during transportation and being damaged, which would affect the subsequent use. At the same time, the anti-slip layer can increase the friction between the inner wall of the protective sleeve 2 and the outer wall of the protective sleeve 104, thereby improving the stability of the protective sleeve 2 on the outer wall of the expansion tube 101 and preventing it from falling off.

[0038] Embodiment 5:

[0039] Reference Figure 1 , Figure 2 , a ureteroscope guide sheath kit is basically the same as Example 1, and further, the surface of the sheath seat 102 is set in an inwardly concave arc shape; when the medical staff holds the sheath seat 102 and extends the sheath tube 1 into the patient's urethra through the conical expansion tube 101, since the surface of the sheath seat 102 is set in an inwardly concave arc shape, it is convenient for the medical staff to better hold the sheath seat 102, providing convenience for the medical staff's work.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
