【Laparoscopy】Commonly used equipment
Minimally invasive surgery is the hotspot and development direction of surgical operations in the future. As clinical surgery increasingly favors minimally invasive surgery, laparoscopic surgery will become more and more. In the implementation of laparoscopic surgery, surgeons rely heavily on equipment and instruments, and the surgical instruments used in surgery are far more than ordinary open surgery. The surgical instrument is the arm extended by the doctor and the terminator of the patient's pain. Its work performance is directly related to the success of the operation and the health of the patient. Therefore, the surgical instrument is one of the most important tools for medical work, and the correct use of the instrument during the surgical process Vital.
At present, minimally invasive surgery is well-known and deeply rooted in people's minds, but everyone just understands the literal meaning, and it is not clear how minimally invasive surgery is performed and how to operate it. Below we will introduce several common laparoscopic instruments.
1. Trocar: It is the channel inside and outside the abdomen for laparoscopic surgery. According to the different surgical instruments, Trocar currently has 5mm, 10mm, 12mm and so on. The inner core of the puncture cone is mainly a cone, which can reduce the damage of various layers of tissue.
2. Electric hook: an important means of intraoperative separation and hemostasis. Especially, it is widely used in the well-known laparoscopic cholecystectomy and appendectomy.
3. Ultrasonic knife: precise and selective breaking of tissues to retain normal blood vessels and nerves, keep the surgical field clear, without smoke and eschar. When the ultrasonic knife works, only a small amount of water vapor is generated, and it does not produce a lot of smoke like the electric knife, which affects the visual field. When the ultrasonic scalpel works, no current passes through the body, and it can also perform surgery for patients with pacemakers.
4. Grasping forceps: Grasping forceps heads can be divided into two types: non-invasive and invasive. Non-invasive grabbing forceps are usually serrated clamping surfaces, with blunt, pointed, straight, elbow, etc.; invasive grabbing forceps are often With claws or hooks, it is often used to firmly clamp some fibrous connective tissue and remove some nodular tissue from the abdominal cavity.
5. Separation forceps: free tissue during operation, separation of intra-abdominal tissue and adhesion.
6. Vascular clips: Vascular clips are made of different materials. Commonly used are metal clips, absorbable clips and Hem-o-lok clips. They are divided into three types: large, medium and small. ligation.
7. Stone removal forceps: When performing biliary tract surgery, the stones can be completely removed to avoid being left in the abdominal cavity.
8. Needle holder: The head of the needle holder is usually a sheath-like or hinge-like structure. The needle holder of the hinge-like structure often has a jaw fixed, and some grooves have grooves on it, so that when sutured in the body It is easier to fix the needle in the needle holder to prevent rotation.
9. Take the bag: take out the surgical excision to avoid the contact between the diseased tissue and healthy tissue, reduce the infection and the residual of pathological tissue.
