Problems solved by technology

[0005] 1. It is necessary to take out the forceps holding the stones from the gallbladder many times, which is easy to cause damage to the gallbladder and increase the pain of the patient;
[0006] 2. In the process of crushing large stones with forceps, small stone particles are easy to fall into the gallbladder, which is difficult to remove and increases the operation time for cleaning

Embodiment 1

[0035] Such as Figure 1-Figure 4 As shown, a device for removing gallstones includes a cylinder body 1. A stone retrieval spoon 2 is fixedly installed at one end of the cylinder body 1. The stone retrieval spoon 2 is hemispherical. Specifically, the cylinder body 1 is a cylindrical cylinder. One end is fixedly installed on the outer wall of the stone fetching spoon by welding, and the gravel horn 3, the water inlet pipe 4 and the water outlet pipe 5 are installed in the cylinder body 1; one end of the gravel horn 3 is connected with an ultrasonic transducer 6 are connected, and the other end of the gravel horn 3 extends into the stone fetching spoon 2; the gravel horn 3, the water inlet pipe 4, and the water outlet pipe 5 are all arranged parallel to the center line of the cylinder body 1; the water inlet of the water inlet pipe 4 end is connected with a water supply equipment, the water supply equipment is not shown in the outer figure of cylinder 1, the water supply equipme...

Embodiment 2

[0040] This embodiment is further improved on the basis of the first embodiment, and the same parts as the embodiment are not repeated.

[0041] refer to figure 1 , figure 2 , image 3 , Figure 4 and Figure 7 As shown, in order to prevent water from colliding with the inner wall of the stone-taking spoon 2 and splashing out of the stone-taking spoon 2 when water is passed into the stone-taking spoon 2, and to bring out the careful stone particles in the stone-taking spoon 2, the application also includes Seal the cover 8 of the stone-taking spoon 2, the cover 8 and the stone-taking spoon 2 are slidingly arranged, the cover 8 is fixedly connected with a connecting rod 9, and the connecting rod 9 is connected with a driving mechanism, and the driving mechanism is used to drive the cover 8 to seal the stone-taking spoon 2. When taking stones, the cover body 8 is moved to the direction of the cylinder body 1 through the driving mechanism so that the lid body 1 and the mout...

Abstract

The invention discloses a device for taking out a gall-stone. The device comprises a cylinder body, wherein a stone-taking spoon is fixedly arranged at one end of the cylinder body, and is of a hemispherical shape; the cylinder body is internally provided with a stone crushing amplitude-change rod, a water inlet pipe and a water outlet pipe; the stone crushing amplitude-change rod, the water inlet pipe and the water outlet pipe are parallel to the center line of the cylinder body; the water inlet end of the water inlet pipe is communicated with a water supply device, the water outlet end of the water outlet pipe is connected with a pump body; one end of the stone crushing amplitude-change rod is connected with an ultrasonic transducer; the other end of the stone crushing amplitude-change rod extends into the stone taking spoon; the water outlet end of the water inlet pipe extends into the stone taking spoon; and a stone removing hole is formed in the bottom of the stone taking spoon and communicated with the water inlet end of the water outlet pipe through a connecting pipe. According to the device, damage to the gallbladder can be reduced, calculi can be removed at a time, and the operation time is shortened.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a minimally invasive device for removing gallstones. Background technique [0002] Stone disease mostly occurs in the urinary system and biliary system, and is a common and frequently-occurring disease. It is mainly treated by extracorporeal shock wave lithotripsy (ESWL), endoscopic stone removal and open surgery. Because extracorporeal shock wave lithotripsy is affected by various interference factors, including the patient's physique, stone quantity, location, activity, and whether it adheres to surrounding tissues, etc., the scope of use and the effect of lithotripsy are greatly reduced. Clinical studies have shown that although extracorporeal shock wave lithotripsy has the characteristics of non-invasiveness and repeated strong operations, repeated lithotripsy on one part often leads to adhesion of stones and surrounding tissues, which must be resolved by open surge...
