hemostatic forceps
Hemostatic forceps are compression tools used to compress and temporarily close blood vessels that are bleeding. The destructive effect on the vessel wall at the site of application stimulates physiological clotting mechanisms. Unlike thumb pliers, they have a ratchet mechanism to maintain the free hand occlusion when the bandage is applied.
Hemostats come in a variety of lengths, shapes (straight or curved), and types. Larger hemostatic forceps are typically used to crush stems and stumps prior to ligation and cutting. Hemostatic clamps are delicate instruments that are worn out and should be checked regularly for jaw alignment, shaft tension, and ratchet wear.
Straight or curved:
Hemostatic forceps are available in a variety of sizes with curved or straight jaws.
mosquito net:
Mosquito clipper jaws have transverse stripes along their length, making them a good choice for clogging small blood vessels. The tip of this tool is usually used to grab and crush bleeding blood vessels. These small hemostatic forceps are delicate and should not be used to ligate large vascular pedicles or to ligate stumps containing a lot of extra tissue.
Kelly tweezers:
Kelly tweezers are larger and less fragile than mosquito tweezers. These forceps only have teeth transversely along the distal side of the jaw. These instruments are available with straight or curved jaws and are often chosen for small and medium vascular occlusion.
Tang-Tang:
Crile tweezers are larger and less vulnerable than mosquito tweezers. These tweezers have teeth that run along the jaw surface and are available with straight or curved jaws. This instrument is often used for the occlusion of small and medium blood vessels.
Karmalt Algae:
Rochester-Carmalt forceps are commonly used in veterinary surgery, especially for ligating pedicles and stumps of blood vessels. Spurs on the jaw surface extend all the way except at the tip of the jaw, where they also run transversely (resulting in transverse stripes). Longitudinal serrations allow easy suture removal during ligation, and transverse protrusions at the ends of the jaws help keep tissue within reach of the instrument. Available with straight or curved jaws.
Satin seaweed:
Satinsky or tangent clamps are designed to non-traumatically occlude a portion of a large blood vessel, such as the vena cava, while allowing blood to flow to the portion of the vessel that is not blocked.
Bull Dog Leash:
Bulldog forceps are used to temporarily close blood vessels during vascular surgery. They are small and relatively light, which is an advantage when working in tight spaces or when there is little support from the surrounding tissue. Several modifications of these clamps are available, some of which allow adjustment of the pressure exerted by the clamp on the vessel wall. Instruments come in different sizes and with straight or curved jaws.
