Clinical calculus removing device for hepatobiliary surgery

Abstract

The invention discloses a clinical calculus removing device for hepatobiliary surgery. The device comprises a collecting shell and a cover plate, wherein the cover plate is arranged at the upper end of the collecting shell; one or more partition plates are vertically installed in the collecting shell; the interior of the collecting shell is divided into one or more storage cavities through the partition plates; the left side of the cover plate is bent upwards to form a fixing part; an installation opening is formed in the middle of the fixing part; a clamping jaw is installed in the installation opening; a pull rope for controlling the clamping jaw to be opened and closed is installed at one end of the clamping jaw; a fixing block is vertically installed on the surface of the cover plate;a positioning hole is formed in the fixing block; a positioning rod is installed in the positioning hole; a pressing block is installed on the right side of the positioning block; the positioning rodis sleeved with a spring; one end of the spring is installed on the fixing block, and the other end of the spring is installed on the pressing block; and the other end of the pull rope is installed onthe positioning rod. The calculus removing device is simple in structure and has a storage function; and clamped calculi can be placed into the storage cavities temporarily until the calculi are completely clamped out, and the calculus removing device does not need to go in and out of the human body back and forth continuously, so that the operation is convenient, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of clinical medicine, in particular to a stone removal device in clinical hepatobiliary surgery. Background technique [0002] Hepatobiliary Surgery mainly studies hepatocellular carcinoma, hepatolithiasis, post-hepatitic cirrhosis and acute liver failure caused by severe hepatitis, which are major diseases that seriously threaten the health of Chinese people. [0003] Hepatolithiasis is a relatively common disease in hepatobiliary surgery. The current method is to cut the corresponding bile duct to remove the stone. However, there are many disadvantages in the traditional operation, such as large surgical incision and strong pain. Therefore, the treatment of hepatolithiasis is gradually Minimally invasive surgery is performed, but the current stone removal device is generally a clamp, which can only clamp one gallstone at a time, causing the clamp to continuously enter and exit the patient's body, which is ...

[0003] Hepatolithiasis is a relatively common disease in hepatobiliary surgery. The current method is to cut the corresponding bile duct to remove the stone. However, there are many disadvantages in the traditional operation, such as large surgical incision and strong pain. Therefore, the treatment of hepatolithiasis is gradually Minimally invasive surgery, but the current stone removal device is generally a clamp, which can only clamp one gallstone at a time, resulting in the need for the clamp to continuously enter and exit the patient's body, which is very troublesome and susceptible to external infection
