Abstract

The utility model provides a flexible double-ball-bag dilitating stone-sucker, belonging to the medical appliance for treating the calculus of ureter, which collects the functions of dilatation, attracting and stone sheathing into an integration. The stone-sucker of the utility model is composed of a pair of lithotomy forceps, two three ways, catheters with double chambers, two switches and the operation handles of the catheters, wherein, the catheters with double chambers which are provided with saccules are arranged on the two three ways, and the switches are arranged on the two three way. The chelae of the lithotomy forceps can extend and open from the operation chamber of the catheter with two chambers, and the chelae can also retract in to the operation chamber.

Description

Flexible double-cavity saccule dilating and aspirating lithotomy device

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of ureteral calculus for the treatment of, medical apparatus and instruments.

Ureteral calculus is to secrete outer commonly encountered diseases, frequently-occurring disease.The present employed apparatus expensive of shock wave lithotripsy therapy that adopts, the medical expense height, and effect is not good enough; Adopt ureteroscopic treatment also to have apparatus expensive, specification requirement height, problems such as easy damaged mucosa; Adopt cover stone indigo plant to get stone, also have following point: 1, there is not extension fixture, often coarse because of calculus, ureter is narrow and small, and entangle after the calculus and draw, and the easy damaged mucosa, 2, easily be obstructed because of intubate, it is just difficult to get stone, and existing dilatation of ureter pipe does not have the stone of getting function again.

The purpose of this utility model provide a kind ofly collect expansion, attraction, cover stone three function is the medical apparatus and instruments of the treatment ureteral calculus of one.

Technical solution of the present utility model is such, it is by the lithotomy forceps that has chela, and a right-angle tee and skew T, the double channel catheter that is contained in the not pass through x-ray in two threeways that has sacculus, two switch and conduit levers that are contained on right-angle tee and the skew T are formed.Two chambeies of double channel catheter are divided into sacculus fluid injection chamber and operating cavity.Sacculus fluid injection chamber only communicates with sacculus and skew T, and operating cavity only communicates with handle hole on right-angle tee and the conduit lever.Chela on the lithotomy forceps inserts from the conduit handle hole, by the clear opening of right-angle tee and the operating cavity in the double channel catheter, stretches out from the other end of operating cavity.Chela on the lithotomy forceps stretches out from operating cavity and can open, also can the retraction operation chamber in.

Accompanying drawing 1 is a shape assumption diagram of the present utility model,

Accompanying drawing 2 is the lithotomy forceps structure chart,

Accompanying drawing 3 is a conduit lever structure chart,

Accompanying drawing 4 is the right-angle tee structure chart,

Accompanying drawing 5 is the skew T structure chart,

Below in conjunction with accompanying drawing this utility model is made detailed description:

Lithotomy forceps 1 is made up of lever 10, pitman 11, steel wire 15, connection tube 14, chela 13.Lever 1 adopts the time of its injection molding, also the available metal material is made, one end of pitman 11 is fixed on the lever 10, the other end is drilled with an aperture, one end of steel wire 15 is fixed in the aperture of pitman 11, fixing in the hole of other end insertion connection tube 14, chela 13 is housed in the hole of the other end of connection tube 14, chela 13 is three elastic wires, one end of three steel wires all is fixedly mounted in the hole of connection tube 14, the other end is evenly distributed opens shape, silver soldering 12 has all been put on the top of every steel wire, makes the top light circle of chela 13 level and smooth, but chela 13 is clamped the one side of calculus and is the coarse shape in plane, so that when operation chela 13 do not damage mucosa, easily clamp calculus again.The conduit lever adopts the time of its injection molding, and also the available metal material is made, and a handle hole is arranged on it.The straight pipe of right-angle tee 3 is installed on the conduit lever 2 by being threaded, be provided with a rubber seal with holes between two contact end faces of right-angle tee 3 and conduit lever 2, the aperture is less than the external diameter of pitman 11, the other end of right-angle tee 3 is connected to the not double channel catheter 6 of pass through x-ray, and double channel catheter 6 usefulness adhesive securement are in the clear opening of right-angle tee 3.Two chambeies of double channel catheter 6 are divided into sacculus fluid injection chamber and operating cavity, and 3 of right-angle tees communicate with operating cavity: the 3rd passage of right-angle tee 3 is connected to switch 9 by connection tube 8.Double channel catheter 6 passes the clear opening of skew T 5 after installing on the right-angle tee 3, adopt adhesive securement, and it is 5～10mm that two threeways are spaced.Sacculus fluid injection chamber only communicates with the oblique through hole of skew T 5, tiltedly on the through hole switch 4 is housed also.Be provided with sacculus 7 from double channel catheter 6 vertical 2mm places, sacculus 7 adopts nonpoisonous emulsion to make, and sacculus 7 length are 12～15mm, wall thickness 0.15mm, and two ends are closed.7 of sacculus communicate with sacculus fluid injection chamber, and the whole passage in sacculus fluid injection chamber is that oblique siphunculus from skew T 5 is to the balloon cavity of sacculus 7.The top ends of double channel catheter 6 is taper, and port light circle is level and smooth.Chela 13 on the lithotomy forceps 1 inserts from the handle hole of conduit lever 2, and the clear opening by right-angle tee 3 is inserted in the operating cavity of double channel catheter 6, can open automatically after the other end of operating cavity stretches out.Chela 13 also can be withdrawn in the operating cavity.

The dislodger that this utility model provides also has a blue operator of cover stone, and its structure is the same with lithotomy forceps 1, and just the chela 13 usefulness cover stone blue 16 on the lithotomy forceps 1 replaces, and the structure of cover stone indigo plant 16 is with of the prior art the same.Like this, have pincers stone and cover stone function with regard to the dislodger that this utility model is provided.

Double channel catheter 6 used in this utility model can also substitute with three cavities conduit pipe, at an intracavity that increases optical fibers is set, and this chamber just claims the optical fibers chamber.The optical fibers chamber is provided with a bright finish, other end eyeglass by an end of chela 13.

When the dislodger that uses this utility model to provide is treated urinary stone, dislodger is entered ureter through cystoscope insertion hole or biopsy handle hole, after arriving at calculus, retreat 30mm, from switch 9, inject an amount of petrolatum, chela 13 is pushed ahead gently clamp calculus then, conduit is pushed ahead tighten up chela 13 through operating cavity, clamp dilating sacculus after the tight calculus, the calculus of leaving behind gently.

The stone dislodger treatment ureteral calculi that uses the utility model to provide has easy economy, safe and effective characteristics.
