This embodiment is through adding the supplementary scale mark of getting stone basket body front end with the colour is clear, it can help the art person to judge preliminary calculus size immediately to put into the urinary tract intracavity under basket closed state, improve the success rate of getting stone at every turn of art person, reduce the invalid stone action of getting of unnecessary, especially to the higher patient of calculus load, can produce a large amount of little calculus fragments behind the rubble, probably need get stone many times, improve the success rate of getting stone at every turn of art person, the total stone number of times of getting of the art person that will significantly reduce, reduce overall operation time, increase stone basket durability. The embodiment is realized as follows:

referring to fig. 1-3, the present embodiment provides a medical stone-taking basket 3, which includes a basket 3, a tube 2 and a handle 1 connected in sequence; the basket 3 is provided in an ellipsoidal shape, and includes a traction guide wire 31 and a sampling guide wire 32 provided inside the traction guide wire 31, both of which are made of memory iron wire. The pipe body 2 is made of a hose with the size of 1.7Fr, the length can be 115cm or other specifications according to actual needs, and a knob device is arranged on the pipe body and the handheld part 1 and used for controlling the opening and closing state of the net basket 3; the outer surface of the pipe body 2 at one side close to the net basket 3 is also provided with scale marks 5. In a specific use, if the embodiment is required, the diameter of the stone is generally between 1 mm and 10mm, and for this reason, the precision of the scale mark 5 in the embodiment is 2mm as a scale, and the precision can be set according to the actual use condition of a department. The color is arranged in the subareas, so that the diameter of the calculus can be conveniently observed by an operator. The situation that the calculus cannot be pulled out or dragged due to the fact that the size of the residual calculus is estimated by mistake is reduced, and discomfort of a patient in the operation is reduced.

In the present embodiment, in order to adjust the opening and closing degree of the basket 3, the knob device includes a first knob 41 and a second knob 42; the first knob 41 is arranged at the joint of the handheld part 1 and the tube body 2, the second knob 42 is arranged at the joint of the tube body 2 and the net basket 3, and the traction guide wire 31 and the sampling guide wire 32 are respectively fixed on the second knob 42. The traction guide wire 31 is used as an integral external frame of the basket 3, the traction guide wire can be opened and closed by rotating the second knob 42, the sampling guide wire 32 is arranged inside the traction guide wire 31 in geometry, the distribution density of the sampling guide wire 32 in space is greater than that of the sampling guide wire 32, the specific density and winding mode are not limited in the embodiment, and the calculus can be taken out in practical use.

In order to achieve a good lithotomy effect, the fixing points of the traction guide wire 31 on the second knob 42 are distributed on the periphery of the sampling guide wire 32, so that the traction guide wire 31 and the sampling guide wire 32 form a pattern of inner and outer inclusion. The basket 3 comprises a connecting end 81 and a converging end 82, and the end point of the converging end 82 is a connecting point of the traction guide wire 31 and the sampling guide wire 32. The connecting end 81 is the part of the basket 3 connected with the second knob 42, and the far end of the converging end 82 is a connecting point, so that the calculus can enter the space of the basket 3 through the gap of the traction guide wire 31 and is supported by the sampling guide wire 32. The opening and closing size of the converging end 82 is adjusted, so that the calculus can be safely taken out. For the convenience of taking out, the knob device further comprises a locking knob 43, and the locking knob 43 is arranged at one end of the handheld part 1 far away from the tube body 2. The utility model aims to fix the opening and closing size of the basket 3 and avoid the falling of the calculus caused by the rotation of a knob in the moving process. Meanwhile, the first knob 41, the second knob 42 and the locking knob 43 are made of a light stainless material in consideration of the environment of the lumen of the human body.

In use, the safety indicator 6 is provided on the outer surface of the hand-held portion 1 in this embodiment for safety reasons, and the safety indicator 6 is made of a light elastic material such as rubber, silicone or sponge, and the outer surface thereof is provided with a color mark. The patient discomfort is caused by the fact that the operator stretches too deeply when operating. Different departments and operating environments can determine the position of the safety prompting device 6 on the handheld part 1 according to the guide. Meanwhile, in order to facilitate the operation of an operator and smoothly drag the calculus, please refer to fig. 2 again, a holding part 7 is further arranged on the hand-held part 1, so that the operator can hold, hold and drag the calculus conveniently.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
