Handle is provided with labelling；The labelling is open in the same plane with described, or may be contained within the same side of the body of rod, or
It is respectively arranged at the corresponding both sides of the body of rod；Relative to the body of rod, the overall distribution arrangement of the handle, with the body of rod
Bearing of trend it is in the same direction；Relative to the body of rod, the overall distribution arrangement of the hook head, the bearing of trend with the body of rod
It is mutually perpendicular to.
Used as further optimizing, above-mentioned handle can integrally be set to the polygonal profile shape crotch containing a fracture, or
It is the circular contour shape crotch containing a fracture.Fracture between by arranging on the handle, you can will around here fracture as labelling,
The real-time azimuthal for understanding the opening between hook head and the body of rod is grasped to corresponding, and then is easy to aim at and hook as early as possible in operation
Take.The above-mentioned polygonal profile shape crotch containing a fracture, specifically can be curved using the triangular-shaped profile shape containing a fracture
The routine polygonal profile shape crotch such as hook, square profiles shape crotch.
Used as further optimizing, the maximum transversal length between above-mentioned bottom curved arc section and the above-mentioned body of rod is than above-mentioned top curved arc
Maximum transversal length between section and the above-mentioned body of rod will be grown.The top of its hook head can more carefully smoothly enter urethra, bottom compared with
Width can smoothly tick Ureteral stent tube.
Used as further optimizing, the tangent line of above-mentioned hook head end points to above-mentioned top curved arc section and above-mentioned bottom curved arc
The side of section connection.
To be further ensured that above-mentioned hook head, the above-mentioned body of rod are with above-mentioned handle in approximately the same plane using safety.
Used as further optimizing, above-mentioned top curved arc section is connected with the above-mentioned body of rod；Above-mentioned bottom curved arc section is distributed in above-mentioned
Inner side between the body of rod and the top curved arc section.By the setting, bottom curved arc section has been bent towards between the body of rod and top curved arc section
Inner side, that is, define secondary later hook, reduce the least significant end of bottom curved arc section --- i.e. the end of hook head, it is straight with human body
The probability of contact, and then avoid damage human body mucosa in use.
Used as further preferred, above-mentioned Ureteral stent tube removes hook integrally using the steel wire of a diameter of 1.35mm, head
Portion's bending is obtained in round, and its overall length is 30cm, and its steel wire upper end is involved in encloses interior, forms the opening of wide about 2～5mm.
This utility model has the advantages that：
This utility model removes hook there is provided a kind of Ureteral stent tube, and which is reasonable in design, and its hook head is secondary
Later hook, reduces the least significant end of bottom curved arc section --- i.e. the end of hook head, the probability with direct body contact, and then
Avoid damage human body mucosa in use；The top of hook head can more carefully smoothly enter urethra, and the wider energy in bottom is smooth
Tick Ureteral stent tube；In structure, the overall distribution arrangement of the handle distribution arrangement overall with hook head mutually hangs down
Directly, easily hold during operation, be sure of, being difficult to skid, conveniently hooking up, realizing more steady, more accurate manipulation；By on handle
If a labelling, the real-time azimuthal for understanding the opening between hook head and the body of rod is grasped to correspondence, and then is conveniently taken aim in operation
Accurate and hook up as early as possible, it is higher which hooks up success rate, Clinical practice this when removing hook, it is simple to operate which removes art, without the need for anesthesia, peace
Entirely, it is painless, without complication, its average success rate is up to 90.7%；Which is simple for production, draw materials easily, greatly reduces patient doctor
Treatment expense and medical treatment cost.The Ureteral stent tube removes hook, it is adaptable to female outpatient patient's indwelling Ureteral stent tube
Remove.
