Description

Miniature multi-function is grabbed the shape dislodger

Technical field

This utility model belongs to a kind of medical device of removing calculus, is specifically related to a kind of miniature multi-function and grabs the shape dislodger.

Background technology

At present, the Therapeutic Method of domestic ureteral calculus is mostly taked surgical calculus removing or rubble therapy, the operation of these Therapeutic Method is complicated, not only damage normal when injected organism tissue, increased patient's misery, and easy infection, side effect is big, medical expense is high, and the patient is difficult to bear sensual misery and burden economically.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and make simple, easy to operate, patient's no pain, do not have infects, have no side effect, production cost and medical expense is low, safe and reliable, collect angiographic diagnosis, Drug therapy and get the new micro multi-functional shape dislodger of grabbing that stone is one.

This utility model has taked following technical scheme to realize: be provided with the stone taking device that two ends are stretched out outside the conduit and can be moved in conduit in a surface has the conduit of scale sign, described stone taking device is to be provided with the elastic wire that little hook and merogenesis be fixed together by three one ends to constitute, described three elastic wires are provided with an end of little hook and stretch out to three different directions, the top inwardly is the gripper shape, three steel wires are provided with transportable sleeve pipe, and the direction opposite with little hook is provided with positioning screw cap; Described stone taking device is matching used with it to be to be provided with the no steel wire ureter guiding flexible pipe that two ends are stretched out conduit and can be moved in conduit, and described no steel wire ureter guiding flexible pipe rear end is provided with gim peg;

Described three gripper length are respectively 15mm, 16mm and 17mm, and grapple is long to be 1mm;

It is 6mm that described no steel wire ureter guiding flexible pipe front end stretches out conduit.

Owing to adopted technique scheme, get stone and rubble calculus technology is compared with existing operating on, have following beneficial effect: the one, make simple, easy to operate; The 2nd, adopt miniature multi-function to grab the shape dislodger and get that stone is not operated on, rubble not, patient's no pain, do not have and infect, have no side effect; The 3rd, medical expense is low; The 4th, safe and reliable; The 5th, adopt existing medical ureter guide wire to make source material, to draw materials easily, production cost is low; The 6th, when stone taking device is placed in the conduit supporting use, can get stone, the ureter guide wire places in the conduit, can angiographic diagnosis, can the treatment of perfusion liquid, have angiographic diagnosis, Drug therapy and get multiple function such as stone.

In the drawings: 1, conduit 2, stone taking device 3, little hook 4, elastic wire 5, gripper 6, sleeve pipe 7, positioning screw cap 8, no steel wire ureter guiding flexible pipe 9, gim peg 10, calculus

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments:

As shown in Figure 1, in having the conduit (1) of scale sign, a surface is provided with the stone taking device (2) that two ends are stretched out outside the conduit (1) and can be moved in conduit (1), described stone taking device (2) is to be provided with the little hook (3) of 1mm length and elastic wire (4) formation that merogenesis is fixed together by three one ends, described three elastic wires (4) are provided with an end of little hook (3) and stretch out to three different directions, the top inwardly is gripper (5) shape, the length of three grippers (5) is respectively 15mm, 16mm and 17mm, three elastic wires (4) are provided with transportable sleeve pipe (6), and the direction opposite with little hook (3) is provided with positioning screw cap (7); As shown in Figure 2, described stone taking device (2) is matching used with it to be to be provided with the ureter guide wire (8) that two ends are stretched out conduit (1) and can be moved in conduit (1), and described ureter guide wire (8) rear end is provided with gim peg (9); Described ureter guide wire (8) front end stretches out the long 6mm of conduit (1).

Work process of the present utility model is as follows:

Carry out ureteral calculus when getting stone at needs, spy on down cystoscopic, 8 insertions of ureter guide wire are had in the conduit 1 of scale sign, ureter guide wire 8 two ends are stretched out outside the conduit 1, gim peg 9 insertion conduits 1 rear end of ureter guide wire 8 is fixed, ureter guide wire 8 can not be free to slide in conduit 1, the length that the front end of ureter guide wire 8 stretches out conduit 1 is 6mm, front end and conduit 1 intersection with a little wax seal ureter guide wire 8, be convenient to the smooth intubate of ureter, after the intubate success, ureter guide wire 8 is extracted out from conduit 1, the sleeve pipe on the stone taking device 26 being pushed to gripper 5 one ends draws gripper 5 in again, then sleeve pipe 6 is aimed at the rear end of conduit 1, the gripper 5 of elastic wire 4 and gathering is sent in the conduit 1 together, with positioning screw cap 7 stone taking device 2 is fixed according to the location positioning of calculus, when conduit 1 and stone taking device 2 are delivered to calculus 10 places, the gripper 5 that stone taking device 2 front ends close up is sent conduit 1, as shown in Figure 3, because the elastic reaction of elastic wire 4, gripper 5 opens.As shown in Figure 4, then from the afterbody of stone taking device 2 with stone taking device 2 suitably pumpback from conduit 1, move after driving gripper 5 because the squeezing action of conduit 1 wall, gripper 5 is closed up calculus 10 caught and hauls out external together with conduit 1.

When no steel wire ureter guiding hose 8 flexible pipes in placing conduit 1 and conduit 1 inserts in the Ipsilateral ureter in addition, will not have the extraction of steel wire ureter guiding hose 8 flexible pipes after, can carry out pyelography and diagnose, also can utilize conduit 1 to carry out treatment of drug perfusion.
