There are four side strips described in the utility model.

The stone ring of the utility model is made of elastic material.

Compared with the prior art, the utility model has the following obvious effects: 1. The structural design is reasonable; 2. The stone removal effect is good, and the operation is convenient and safe.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

Below in conjunction with accompanying drawing and through embodiment the utility model is further described.

Example:

Referring to Figure 1, the utility model embodiment includes a fixed handle 1, a movable handle 2, a fixed bolt 3, a tie rod seat 4, a fixed hole 5, a tie rod cover 6, a screw sleeve 7, a fixed sleeve 8, a clamp rod 9, and a clamp rod seat 10 , pull bar 11, cover stone circle 12, cover stone basket 13.

Fixed handle 1 and movable handle 2 are connected and fixed with fixed bolt 3 and can rotate. The rod seat 4 is provided with a fixing hole 5, and one end of the movable handle 2 is inserted into the fixing hole 5. The screw sleeve 7 is inserted into the draw rod sleeve 6, the draw rod seat 4 is inserted into the draw rod sleeve 6, the draw rod sleeve 6 is inserted into the fixed handle 1, the fixed sleeve 8 is inserted into the draw rod sleeve 6 and fixed with the screw sleeve 7, the clamp rod 9 and the clamp rod seat 10 are welded and fixed, and the clamp rod seat 10 and the pull rod cover 6 are tightened and fixed.

The stone ring 12 is connected and fixed with the stone basket 13, and the stone ring 12 is welded and fixed with the pull rod 11. The stone ring 12 includes four side bars 14 , and the four side bars 14 are cross-connected to form the helical stone ring 12 .

The pincer bar 9 is sleeved on the pull bar 11 and the pull bar 11 penetrates the pincer bar 9, passes through the pincer bar seat 10 and the bar cover 6 and is welded and fixed with the bar seat 4.

In the silt-shaped calculus operation, the calculus can be poured into the set stone basket 13 from the set stone circle 12, so that the silt-shape calculus is all poured into the set stone basket 13. After the organ tube at the calculus site is washed, the tissue at the calculus site will be free of calculus and sediment, ensuring the integrity of the calculus removal operation.

As long as hold the handle tightly, the pull bar seat 4 pulls the pull bar 11, and the pull bar 11 pulls the stone ring 12, and the stone ring 12 is made of elastic material, and the stone ring 12 retracts into the clamp bar 9, so that the stone basket 13 is sealed.

The utility model can be washed and sterilized with disinfectant, and can also be sterilized with high temperature.
