Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-6, an embodiment that this scheme provided, a novel stone guide sheath is got to ureter negative pressure, including sheath pipe body 1, sheath pipe body 1's outside is fixed with annular plate one 3, sheath pipe body 1's inside is fixed with negative pressure connecting pipe 10, sheath pipe body 1's inside cover is equipped with well pipe body 2, well pipe body 2's outside is fixed with two fixed blocks 4, the both sides of fixed block 4 all are fixed with fixture block 5, well pipe body 2's inside cover is equipped with expansion pipe body 6, the outside cover of the left end of expansion pipe body 6 is equipped with rubber tube 12, the left end of rubber tube 12 exceeds the left end of expansion pipe body 6, the outside of expansion pipe body 6 and the outside of well pipe body 2 all are fixed with rubber ring 14, expansion pipe body 6's outside is fixed with annular plate two 7, two spouts 8 have been seted up on annular plate one 3 and the annular plate two 7.

In this embodiment, the vertical section of the sliding chute 8 is of a shape of a pair, and the fixture blocks 5 are all sleeved in the sliding chute 8.

In this embodiment, the external portion of the dilating tube body 6 is fixed with the holding piece 9, the external portion of the holding piece 9 is provided with anti-slip threads, and the holding piece 9 is convenient for a doctor to draw out the dilating tube body 6.

In this embodiment, be fixed with the connection rope on the sheath pipe body 1, the other end of connecting the rope is fixed with sealed lid 11.

In this embodiment, a sealing ring is fixed inside the sealing cover 11, and the sealing ring is sleeved outside the negative pressure connecting pipe 10.

In this embodiment, the finger ring 13 is fixed outside the sheath tube body 1, and the vertical section of the rubber ring 14 is a conical structure.

The working principle is that firstly, under medical images, whether calculi exist in a ureter, a bladder and a kidney or not is observed, then the position of the calculi is determined, a guide wire is placed in the external orifice of the urethra, then the guide wire penetrates into an expansion tube body 6, then a negative-pressure calculus removing guide sheath of the ureter is placed to a calculus removing position under the guide of the guide wire, a rubber tube 12 wraps the advancing end of the expansion tube body 6 when the negative-pressure calculus removing guide sheath of the ureter moves in the body, the condition that the advancing end of the expansion tube body 6 scrapes in-vivo tissues and damages the in-vivo tissues is avoided, a connecting gap is formed between the expansion tube body 6 and a middle tube body 2 as well as a sheath tube body 1 when the negative-pressure calculus removing guide sheath moves, the in-vivo tissues are also scraped by the gap, so that the rubber ring 14 shields the gap, when the expansion tube body 6 is taken out, the left end of the middle tube body 2 abuts against the rubber ring 14, and the rubber ring 14 is turned over when the expansion tube body 6 is pulled, therefore, the drawing of the expansion tube body 6 cannot be obstructed, the drawing of the middle tube body 2 is the same, the prior ureter negative pressure calculus removing guide sheath only comprises the expansion tube body 6 and the sheath tube body 1, so when the ureter negative pressure calculus removing guide sheath enters the body, the foreign matters in the body can enter the interior and the surface of the advancing end of the expansion tube body 6, the foreign matters on the surface of the advancing end can be adhered to the surface of the sheath tube body 1 when the expansion tube body 6 is taken out, the foreign matters can be shielded when a urethral soft lens enters the ureter, the later operation is inconvenient, the middle tube body 2 is arranged, the foreign matters are left on the inner wall of the middle tube body 2 at the advancing end of the expansion tube body 6, then the middle tube body 2 is drawn out, the residual foreign matters are taken out by the middle tube body 2, the inner wall of the sheath tube body 1 is clean, the foreign matters are reduced, the shielding is avoided, the clamping block 5 fixes the three, and the sealing cover 11 seals the negative pressure connecting tube 10, avoiding the entry of bacteria.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered as the technical solutions and the utility model concepts of the present invention in the scope of the present invention.
