Specific implementation mode
To keep the purpose of this utility model, technical solution and advantage clearer, with reference to specific embodiment to practicality
It is novel to carry out clear, complete description.
A kind of ureter guide sheath as shown in Fig. 1, including sheath tube assembly, dilator tube component and holding part 3, it is described
Sheath tube assembly includes sheath 11 and the sheath pipe fitting 12 that is connect with 11 tail end of the sheath, and the dilator tube component 2 includes
Dilator tube 21 and it is connect expander connector 22 with 21 tail end of the dilator tube, the dilator tube 21 is inserted in the sheath
In pipe 11, the front end of the dilator tube 21 stretches out in outside the front end of the sheath 11, when being inserted into ureter, expander and sheath
Pipe is inserted into together, is expanded to ureter.
As shown in Fig. 3, the holding part 3 include two handles 31, positioned at two 31 front ends of handle grab 32 and
Lantern ring 33 between two handles 31 is axially provided with multiple card ribs 34 on 33 inner wall of the lantern ring, the card rib 34
Section is reverse V-shaped structure, is advisable with being uniformly distributed, and axially position and fixed can be played the role of.
As shown in Fig. 2, the outer wall of the expander connector 22 is provided with for determining positioning before and after the lantern ring 33
Position bulge loop 23, offers multiple card slots compatible with the card rib 34 24 on the expander connector 22；Card slot and card rib phase
Adaptation, plays the role of axially position.
As shown in Fig. 4, be provided with chuck 13 compatible with the grab 32 on the sheath pipe fitting 12, when need by
When sheath tube assembly and dilator tube component are fixed, clamping piece 3 is sleeved on expander, is fixed with grab and chuck, realizes card
Connect fixation.
The dilator tube component, sheath tube assembly and clamping piece of the utility model can be separated from each other and be combined with each other, in group
When conjunction, the expander connector 22 is inserted in the lantern ring 33, and the card rib 34 is in the card slot 24, the lantern ring
33 is inconsistent with positioning convex ring 23, and the grab 32 fastens with the chuck 13 so that dilator tube component, sheath tube assembly and
Clamping piece is fixed, and avoids loosening and detaching in operation.
When progress ureterectasia is used alone in the dilator tube component of the utility model, can not only it have to plus with clamping
Part is conveniently operated.After the completion of being expanded, dilator tube can be inserted into sheath, then by clamping piece from far from expander
One end of pipe is placed on dilator tube connector, and clamping piece does not have to contact dilator tube and sheath, and expander connector 22 is justified for reducing
Mesa-shaped structure, including preceding linkage section 22a, convex ring segment 22b, card slot section 22c and rear linkage section 22e, the convex ring segment
The outer diameter of 22b is more than the outer diameter of preceding linkage section 22a and card slot section 22c, and the outer diameter of the card slot section 22c is more than the rear linkage section
The outer diameter of 22e is provided with the changeover portion 22d of outer diameter gradual change, the card between the card slot section 22c and the rear linkage section 22e
The cross section of slot 24 is V-groove, it is thus only necessary to move the card rib of lantern ring 33 along card slot smooth, during which be not necessarily to use
Power.
When dilator tube is taken out, while two handles are pressed, handle generates extruding to lantern ring, makes the card rib of symmetry direction
It is closely contradicted with card slot, forms chucking power, dilator tube is taken out of, realize the mesh that its firm clamping dilator tube connector is detached from
, under the premise of need not be destroyed to clamping piece, you can detach clamping piece and dilator tube, can recycle, and is full
It needs to dismantle the demand that clamping piece is operated during foot is clinical.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It can still modify to the technical solution recorded in previous embodiment, or be equal to which part technical characteristic
It replaces；And these modifications or replacements, the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
