Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a lithotripter for hepatobiliary stone surgery. Background Art

[0002] The hepatobiliary surgery department mainly studies major diseases that seriously threaten the health of Chinese people, such as hepatocellular carcinoma, hepatobiliary stones, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis. For the treatment of hepatobiliary stones, if the patient's stones are relatively small, that is, no more than 1 cm, and there are no lesions, conservative treatment can be selected, but if the stones are larger than 1 cm, surgical treatment is recommended. Especially for surgical treatment methods, laparoscopic technology is used to first make an incision in the patient's abdomen, and then make a small incision at the affected area, and the stones are removed by grasping or suction. In the specific operation process, the stone removal method needs to be selected according to the size of the stone, such as the removal of complete stones, stones that were not completely discharged during extracorporeal lithotripsy, or sand-like stones.

[0003] In the prior art, during the process of removing stones, a stone bag needs to be inserted first, and the removed stones are placed in the stone bag and taken out of the body. Near the end of the operation, the stone bag is pulled out to complete the stone removal process. The process is relatively cumbersome, and therefore a stone remover for hepatobiliary stone surgery is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1, by Figure 1-3 Shown is a stone remover for hepatobiliary stone surgery, comprising a first shell 1 and a second shell 2 mounted on the top of the first shell 1, wherein a storage mechanism 3 for temporarily storing stones is provided in the first shell 1;

[0022] The storage mechanism 3 includes a mounting frame 301 installed inside the first housing 1 . A rubber pad 302 is arranged inside the mounting frame 301 . A long rod 303 is movably connected inside the rubber pad 302 . A protrusion 304 is installed at the bottom end of the long rod 303 .

[0023] Specifically, the top end of the long rod 303 passes through the second shell 2 and extends to the outside of the second shell 2. A handle ring is installed at the top end of the extension section. This structure can lift the stones that fall into the first shell 1 onto the rubber pad 302 for temporary storage.
