Description
Technical field
The utility model relates to a kind of urological department medical instruments, and in particular to a kind of calculus plugging device.
Background technique
In recent years, the operation of rubble is more and more under ureteroscope, in ureteroscope lithotrity, with rubble energy
Increase, calculus drift rate also gradually increases.The calculus of drift usually needs further surgery to handle because fragment is excessive, such as defeated
Urinary catheter soft lens lithotrity, Flexible ureteroscope are trapped stone art or ESW work, and patient suffering is not only increased, and are extended operating time, are more increased
The risk and medical treatment cost of postoperative infection fever.More importantly residual stone fragment will become new at the lithophysa heart, it is secondary on
Urinary tract infections and renal colic bring more pains to patient.Therefore, calculus drift in art is reduced, it is defeated for increasing calculus clearance rate
The major issue of urinary catheter mirror lithotrity.
CN203591285U discloses a kind of calculus plugging device, including outer sheath, inner core and propeller, and inner core is arranged outside
In sheath, propeller is mounted on the proximal end of outer sheath, and one section of the inner core far-end is set as retractility memory alloy spring.
Although the utility model reduces calculus in art to a certain extent and drifts about, calculus clearance rate is improved, the utility model is reliable
Property it is not high because the utility model is to realize sealed condition and flexible by the expansion and contraction of retractility memory alloy spring
Property memory alloy spring be inserted and removed from, and be usually to need high temperature stimulation just to occur for retractility memory alloy spring
Memory phenomenon, and hot environment can not be created in human body, and can retractility memory alloy spring shrink and shrink
Degree cannot all control, and reliability is lower.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of calculus plugging device, it
Calculus can not only be reduced in art to a certain extent to drift about, improve calculus clearance rate, also have and facilitate manual control, reliability compared with
High feature.
In order to solve the above technical problems, the utility model proposes technical solution are as follows: a kind of calculus plugging device, including promote
Device, outer sheath and inner core, the inner core are equipped with the utricule of energy folding and unfolding, and the utricule is connected to by perfusion tube with propeller, institute
The inside that outer sheath and inner core is arranged in perfusion tube is stated, sealing is equipped with physiological saline in the propeller, and the inner core is equipped with
The through-hole being connected to utricule.
As a further improvement of the above technical scheme: the utricule is spherical structure when being full of expansion by physiological saline,
Not only there is preferable plugging effect, but also corner angle are not present, safety in utilization is higher.
Further, the inner core is passed through from the center of utricule, is coated on utricule in it inner core when being unfolded, and guarantees envelope
Stifled effect is preferable.
Further, the inner core and outer sheath are hollow structure, and the utricule can be received into when shrinking by through-hole
In inner core.
Further, the outer sheath and inner core are vacuum structure.
Further, the outer surface is smooth structure, guarantees that the presence of utricule will not damage human body, capsule
Body can be used nontoxic, elastomeric processing of high molecular material and be made, and the wall thickness of utricule is 0.05-0.1mm, both can guarantee its expansion
When structural stability it is higher, and can guarantee its convenient for storage.
Further, the diameter of the inner core is less than the diameter of outer sheath, and the outer diameter of the outer sheath is 0.6-0.8mm,
Ureter is passed in and out convenient for outer sheath and inner core.
Further, the propeller is injector for medical purpose, and material is easy to get, and structure is simple, and cost is relatively low.
Compared with the prior art, the advantages of the utility model are:
1, the utility model is provided with perfusion tube and utricule, and physiological saline is provided in propeller, is pushed away by control
It into device and perfusion tube, can control whether physiological saline is full of utricule, as physiological saline fills utricule, utricule can be made to expand,
And then the effect of closure is played, when not needing to block, physiological saline is extracted out by propeller, shrinks utricule, and is final
It is collected in inner core, guarantees that the presence of utricule will not influence in inner core disengaging ureter, utricule is driven by outer sheath and inner core
Ureter is passed in and out, and guarantees that utricule forms sealed condition around calculus;
2, the utility model forms sealed condition using utricule, and reliability is higher, passes through propeller control physiological saline
The expansion and contraction of control utricule can be realized in flow direction, uses the phenomenon that physiological saline is without utricule leakage is worried,
Safety is also higher;
3, the utility model structure is simple, and cost is relatively low, easy to operate, facilitates carry out manual control, convenient for according to patient
Actual conditions, select the practical charging quantity of utricule, using flexible is also higher, weakens the pain of operation and conducive to the complete of calculus
Portion's discharge.
