Description

Technical Field

[0001] The present invention relates to the technical field of surgical instruments, and specifically to a hemostat for hepatobiliary surgery with an auxiliary stabilizing structure. Background Art

[0002] Surgical instruments refer to various tools and devices used in surgical operations and related medical procedures to achieve functions such as cutting, hemostasis, suturing, clamping, and fixing, thereby assisting doctors in completing surgical operations, treating diseases or injuries. In hepatobiliary surgery, hemostats are often used to stop bleeding in patients to prevent various physical indicators of the patients from being in danger due to blood loss.

[0003] Currently, the hemostat for hepatobiliary surgery uses the heat generated by high-frequency current to evaporate the water in tissue cells and denature proteins, thereby achieving the functions of cutting, hemostasis, and blood coagulation. This hemostat has a fast cutting speed and high hemostasis efficiency, and can adjust the current intensity according to different surgical requirements. It is commonly used in hepatobiliary surgery to incise the skin, subcutaneous tissue, and liver capsule, etc. However, during the surgical process, the hemostat is easily contaminated by blood stains, and it takes extra time to clean the hemostat, resulting in an extended surgical time and an increased probability of patient accidents.

[0031] Specifically, by pressing down the rotating component to make it rotate around the rotating shaft 7, the rotating shaft 7 provides a rotation fulcrum for the rotating component, and the fixing block 6 ensures the stability of the rotating component during rotation. Then, the rotating component drives the first clamping block 10 to slide on the inner wall of the first connecting block 3. After that, the connecting component slides along the inner wall of the second connecting block 4 under the drive of the first clamping block 10. Subsequently, the connecting component slides out of the second connecting block 4 and slides into the interior of the first connecting block 3. At this time, the connecting component is no longer connected to the first connecting block 3 and the second connecting block 4, and the first connecting block 3 and the second connecting block 4 are separated.
