Description

Technical Field

[0001] This utility model relates to the field of surgical instrument technology, and in particular to a monopolar and bipolar hybrid closure device. Background Technology

[0002] Existing technology, patent CN220833105U, discloses a dual-trigger, contact-fitting laparoscopic surgical instrument. In this instrument, the housing has a handle. A first jaw tube connects to a fixed jaw; a second jaw tube connects to a movable jaw. The closing trigger is hinged to the housing. Rotation between the release and closed positions drives the second jaw tube to move between the front and rear ends of the jaws, thus opening or closing the jaws formed by the fixed and movable jaws. A cutting drive connects to a cutting blade to drive its back-and-forth movement. The cutting trigger is hinged to the housing. Rotation between the cutting and avoidance positions drives the cutting drive to move between the cutting front and rear ends. The cutting trigger in the avoidance position engages with the closing trigger in the release position. This configuration improves operational efficiency and surgical outcomes.

Therefore, during a single surgery, medical staff need to change different surgical instruments multiple times. This operation is cumbersome and can easily contaminate the surgical field due to untimely hemostasis. Utility Model Content
