Description

Forceps for temporarily blocking blood vessel

Technical Field

The utility model relates to the technical field of medical equipment, specifically indicate a blood vessel blocks tweezers temporarily.

Background

Bleeding is an issue that cannot be completely avoided in surgical operations, especially arterial bleeding, accidental injury to the arterial vessel wall, such as blunt traction injury or acute shear injury, partial or complete interruption of the full-thickness continuity of the arterial vessel wall, as evidenced by a laceration in the arterial vessel wall or complete rupture of the arterial vessel. One of the conventional hemostasis modes is to suck blood by using a suction apparatus, and after a bleeding point is found, the double-electrode electric coagulation forceps are used for electrically cauterizing a blood vessel wall lacerated part or a broken end, so that protein at the blood vessel wall lacerated part or the broken end is denatured, and the blood vessel wall is blocked, thereby achieving the purpose of hemostasis. Arterial bleeding is usually jetting, particularly, an arterial blood vessel is completely broken and has two broken ends, the two broken ends bleed simultaneously, the bleeding amount is large in a short time, the operation visual field is quickly blurred, the broken artery still bleeds while blood is sucked by an aspirator, a certain degree of difficulty is brought to searching for a blood vessel laceration or a broken end in a blood pool, the time for searching for the artery blood vessel laceration or the broken end is prolonged, the bleeding amount is increased, for the existing blood vessel blocking tool, after the blood vessel is clamped, the hand of a medical worker is required to be kept stable, once the hand cannot be kept stable, if the force application is large, the blood vessel can be damaged, and if the force application is small, the blocking effect cannot be ensured.
