Description

Gallstone taking and breaking device under laparoscope

Technical Field

The utility model relates to the technical field of medical tools, especially, relate to a gallstone lithotripsy device is got to gall-stone under peritoneoscope.

Background

At present, in the technical field of medical treatment, the treatment of gallstones is mainly a minimally invasive surgery treatment means, and the treatment method is to use a corresponding tool to take out the gallstones under a laparoscope, so that the purpose of treatment is achieved. In the biliary tract calculus removing operation, the calculus removing basket is a necessary instrument, but the prior commonly used calculus removing basket has the following defects in use: the large gallstone cannot be taken out through the sinus even after the trabecular is pulled hard, so that complications such as biliary tract or sinus bleeding, perforation and the like are easily caused, and even the calculus cannot be separated from the trabecular basket and needs to be subjected to laparotomy.

Disclosure of Invention

In view of this, the utility model aims at providing a gallstone lithotripsy device under peritoneoscope aims at overcoming current lithotripsy basket and can't carry out the rubble, get the defect of stone to great calculus.

In order to achieve the purpose of the utility model, the technical proposal is as follows:

the utility model provides a gallstone lithotripsy device is got to gall-stone under peritoneoscope, includes handle, sheath pipe, basket body and seal wire, the one end and this body coupling of basket of seal wire, the other end passes the sheath pipe is connected with the handle, the handle passes through the seal wire is controlled the stone is got to the basket body, the basket body is set up along circumference by three piece at least basket strips, the basket strip is fixed in the end cap after crossing at basket body top, be provided with the sawtooth on the medial surface of basket strip, the sawtooth sets up along the length direction of basket strip.

Preferably, four to eight basket strips are arranged.

Preferably, the outer side face of the basket strip is provided with the brush hair, the handle can be rotated simultaneously, the guide wire rotates relative to the sheath tube, and then the basket body rotates to drive the brush hair to brush smaller stones on the inner wall of the biliary tract and take away the stones.

Preferably, the surface of the handle is provided with a groove matched with fingers.

Furthermore, the groove is provided with anti-skid lines.

The utility model has the advantages that:

(1) be provided with the sawtooth on the medial surface of basket strip, can get the stone behind the crushing with great gallstone clamp through the sawtooth that sets up on the basket strip when using, overcome the current defect that gets the stone basket can't carry out the rubble, get the stone to great stone.

(2) The outer side face of the basket strip is provided with the brush hair, the handle can be rotated simultaneously, the guide wire rotates relative to the sheath tube, and then the basket body rotates to drive the brush hair to brush smaller stones on the inner wall of the biliary tract and take away the stones.
