Scalpel (1), the bow-type: is commonly used to wield the law for a long skin incision and the rectus anterior sheath incision (2), write: for dissecting blood vessels, nerves, peritoneal cut and a short incision (3) grasping type: used to force a larger incision. Such as amputations, tendon cut, a long skin incision (4), anti-pick type: used for the abscess to prevent damage to deep tissue.
Surgical Scissor: According to its structural features are sharp, blunt, straight, curved, The long and short various types. According to the organization cut its use is divided into lines cut and stitches cut. Organizations cut for curved scissors, sharp and fine for anatomy, cut or separation cut tissue. Usually shallow operative to direct shear, deep surgical operation with curved scissors.
Forceps: The forceps is mainly used to clamp blood vessels or bleeding points, also known as the hemostat. Forceps The main difference in the structure of the alveolar bed, due to the need of surgical procedures, the alveolar bed is divided into straight, curved, angled, curved (such as the renal pedicle clamp). Forceps for vascular surgery, the alveolar tooth smaller, lighter, better flexibility, press on the organization and its effects on blood vessel walls, intimal injury were mild, said no damage forceps.
Clamp: The front-end smooth, easy to insert the fascia and difficult to pierce the vein, but also for the separation of anatomic tissues. Also be used for traction sutures, pull out the stitches, or on behalf of tweezers to use, but should not be gripping the skin, organs and more delicate tissues. Used to stop bleeding cutting edge should be perpendicular to the organization, grip the ends of the bleeding vessel, minimize the folder nearby tissue.
A. Curved forceps: used to clamp deep tissue or visceral vascular hemorrhage, the length of two kinds.
B. Straight forceps: used for gripping the shallow tissue hemorrhage, and assist needle injection use.
C. Tooth forceps: for clamping thick organizations and slippery vascular hemorrhage within the organization, such as the mesentery, omentum, front teeth prevent slippage, but not for the subcutaneous hemostasis.
D. Mosquito forceps: a small and delicate forceps, straight, bend two kinds of organs, facial and plastic surgery to stop bleeding, and not to do large organization clamp.
Surgical Tweezers: Toothed forceps: also known as tissue forceps, tweezers tip of toothed gear is divided into coarse teeth, fine teeth, and coarse toothed forceps for holding the hard tissue injury, fine toothed forceps for fine surgery. such as suture, plastic surgery. The tip of the hook teeth, gripping firmly, but with some damage to the organization.
Non-toothed forceps: also known as flat tweezers dressing forceps. Its cutting-edge hook teeth for gripping the fragile tissue, organ, and dressings. Shallow with short forceps operation, deep operation with long tweezers, pointed flat tweezers less damage to the organization for vascular, neurological surgery. Correctly held that the tweezers is the right index finger and middle finger with the thumb, executive two tweezers feet, the upper.
Needle Holders, tow hooks class:
1. Skin retractor: rake retractor for the shallow skin surgery opened.
2. Thyroid retractor, flat hook, traction exposed thyroid site, also commonly used in abdominal surgery for abdominal wall incision, the skin, muscle stretch.
3. Retractor of the appendix: also hook retractor for appendectomy, hernia surgery for abdominal wall traction.
4. Abdominal flat-head retractor): lenient smooth hook, used for abdominal surgery.
5 S-shaped retractor: a, such as “S”-shaped abdominal deep retractors. The use retractors to yarn pad retractor and organization are separated, the tension should be uniform, should not be a sudden force or excessive force, so as not to damage the organization, the right to hold retractors, palm up.
6. Automatic retractor:, abdominal, pelvic, thoracic surgery can be applied to their own fixed pull open. To attract for absorption In addition to the surgical field bleeding, oozing contents in the material, pus, and hollow organs, the surgical field clear, to reduce pollution opportunities.
To attract the head structure and appearance of many single tube and casing type, the rear rubber hose connected to attract bottle stand. Single tube to attract the head for smoking in addition to the surgical field of blood and chest and abdomen of liquid. The head casing to attract mainly used for liquid suction within the abdominal cavity, the external casing with multiple side holes and air intake, you can avoid the greater omentum, bowel wall suck, clogging attract head.
