Further, described target seeker is processed by stainless steel material.
Further, described basket silk is processed by the stainless steel wire rope material.
Further, described butt tube is processed by stainless steel material.
The utility model has the advantages that:
1, four of spherical stone extraction basket basket silks constitute the spherical basket of a similar ball shape, and this structure does not have the bending point, can avoid in getting the stone process damage to the bile duct inwall.
2, the interval of four basket silks is big at interval a lot of than the basket silk of spiral type stone extraction basket, is beneficial to cholelithiasis and gets into basket, has improved the success rate of getting the stone operation.
3, distinctive spherical designs has improved the support force of spherical basket, expands bile duct to greatest extent, and it is inner to make calculus get into spherical basket more easily.
