Multiple free air spaces 5, one end of inner tube 2 are connected with an expander joint 6, and one end of expander joint 6 is provided with a fixed part 61,
And a plug 62 is provided with expander joint 6.One end of corresponding outer tube 1 is connected with a sheath pipe joint 7, and the one of sheath pipe joint 7
End is provided with an auxiliary section 71, and by interfixing for fixed part 61 and auxiliary section 71, expander joint 6 is mutually consolidated with sheath pipe joint 7
It is fixed, and sheath pipe joint 7 mutually turns on free air space 5 and the three of gap 3.
Fig. 1 and Fig. 2 are referred to, outer tube 1 has one first wall 11, and inner tube 2 has one second wall 21, the first wall 11 and second
Gap 3 is formed between wall 21, support member 4 abuts the first wall 11 and the second wall 21, fully ensures that the size in gap 3, avoid the occurrence of
The problem of gap 3 closes, multiple support members 4 are from 21 integral elongation moulding of the second wall, and are connected to the first wall 11, such to set
Meter mode, multiple opposite second walls 21 of support member 4 can be caused to fix, be not in the situation of displacement.Certainly, in other realities
It can also be (not shown) to apply in example, and support member 4 and inner tube 2 and outer tube 1 are separately formed, and multiple support members 4 are integral type, such as
This can be convenient for changing after multiple support members 4 have used long；Or multiple support members 4 are integrally extended into from the first wall 11
Type, and it is connected to the second wall 21；Or portion supports 4 are from 11 integral elongation moulding of the first wall, and the second wall 21 is connected to, separately
A part of support member 4 is connected to the first wall 11 from 21 integral elongation moulding of the second wall, and integrally extends from the first wall 11 more
Individual support member 4 and the 4 mutual stagger setting of multiple support members integrally extended from the second wall 21, the design method so to stagger are interior
During practice, BENDING PROCESS ratio is smoothly, overall soft, and the body of patient will not be caused for pipe 2 and outer tube 1
Any injury, and the thickness of inner tube 2 and outer tube 1 is all thinner, can preferably bend, convenient use.
Fig. 2 and Fig. 3 are referred to, multiple support members 4 are mutually staggered, and multiple support members 4 are along inner tube 2 and outer tube 1
Bearing of trend helically extends, and during practice, facilitates the circulation of water 8, one is formed between adjacent four support members 4
Free air space 5, the free air space 5 growth bar shaped is set, along between inner tube 2 and two support members 4 of the bearing of trend of outer tube 1
Size is more than the size between two other support member 4, and water 8 is circulated more smoothly, and one is formed between adjacent four support members 4
Individual free air space 5, formed with a guiding angle (not shown, similarly hereinafter), the guiding angle prolongs the free air space 5 along inner tube 2 and outer tube 1
Direction setting is stretched, and the angle of the guiding angle is less than angle adjacent in free air space 5, can so play what water 8 was circulated
Guide effect, water 8 is allowed faster to enter the body of patient.
Fig. 1 and Fig. 3 are referred to, a water inlet 10 provides outer tube 1, and the water inlet 10 is connected with free air space 5 and gap 3
Logical, 8 mode of intaking is improved, and can import multiple free air spaces 5 and gap 3, a water outlet from the outside of outer tube 1 by water 8
Mouth 12 is provided in inner tube 2, and extends through out outer tube 1, in addition, being further provided with a passage 72 in sheath pipe joint 7, the passage 72 passes through
If sheath pipe joint 7, and to be coordinated with a pressure adsorption part (not shown, similarly hereinafter), can when inner tube 2 has little obstruction
To carry out attraction effect to inner tube 2 using pressure adsorption part so that stone 9 is more smooth quickly to flow out from inner tube 2, and one is close
Sealing cap is (not shown, similarly hereinafter) located at one end of sheath pipe joint 7, due to the setting of seal cap so that the sealing effectiveness of sheath pipe joint 7
It is good.
Fig. 1 is referred to, the above-mentioned clear stone sheath of ureter low pressure soft lens, when it is in practice, water 8 is in inner tube 2 and outside
Gap 3 between pipe 1 is circulated, then goes to impact stone 9 so that and stone 9 is flowed into inner tube 2 along water 8 to be flowed out from inner tube 2 again,
Due to being provided with multiple support members 4 in gap 3, and multiple free air spaces 5 are formed between multiple support members 4, and sheath pipe joint 7
Mutually turned on multiple free air spaces 5 and the three of gap 3, so, even if inner tube 2 and outer tube 1 can not be kept away in the course of the work
When exempting to occur buckling phenomenon, due to being provided with multiple support members 4 in gap 3, the closing phenomenon in gap 3, water 8 will not be also caused
It can stablize and normally circulate, so that the clear stone sheath of ureter low pressure soft lens can reach the purpose of stability and high efficiency.
Detailed description above is only the explanation of the preferred embodiment of the utility model, and non-therefore limitation is of the present utility model specially
Sharp scope, so, all equivalence techniqueses with carried out by this creation specification and diagramatic content change, and are both contained in the utility model
The scope of the claims in.
