Speaking of scalpel, it is a tool often used in clinical medicine, mainly used to cut and separate tissues, and it is a necessary instrument for surgeons to operate. Medical scalpels are generally divided into blades and handles. The blades are disposable and the handles are not. Other instruments are also not disposable, but are autoclaved each time they are used. The so-called sterilization is to kill all microorganisms, and its purpose is to ensure that patients will not have local infections and complications.
Scalpels use different knives according to different surgical requirements. At present, there are many types of scalpels in clinical medicine. Although some of them are ordinary in shape, some even look like knives, but each has its own strengths. These knives are not only the right-hand man of the doctor, but also the "cold nemesis" of the disease. Today, we will list the types of scalpels commonly used by doctors!
Uses: Cuts the superficial and deep tissues of the skin during surgery. Features: sterile, disposable. Ordinary scalpel is an important instrument for completing various operations. It has various models and wide functions. It is mainly used to cut the skin surface and cut tissue during surgery. Since the blade is single-use, the blade and handle are independent. In addition, the blade is extremely sharp, and nurses must use the forceps to remove the blade to protect herself from being scratched.
Features: There are five working modes: pure cutting, mixed cutting, electrocautery, electrocoagulation, and bipolar electrocautery. Purpose: To control blood loss during surgery, that is, to coagulate the surgical site. It heats the body tissue through the high-frequency high-voltage current generated by the effective electrode tip, and finally separates and coagulates the tissue to achieve the purpose of cutting and hemostasis. Since its main function is to stop bleeding during surgery, it is mostly used in surgeries that require timely hemostasis. At present, it is not only widely used in general surgery, thoracic surgery, brain surgery, maxillofacial surgery, but also in various endoscopic surgery.
Features: Argon gas protection cutting, argon arc jet coagulation. purposes : can cure trachea and internal organs diseases. Argon knife is a new generation of high-frequency electrosurgical knife that has been clinically applied in recent years. The scalpel is a flexible endoscopic instrument with a length of nearly 1 meter, which is placed along the oral physiological cavity to the lesion, and then uses ionized argon gas to deliver high-frequency current to the target tissue, and uses the thermal effect to cause the tumor tissue to lose its function. Live, dry and necrotic, so as to achieve the purpose of treating trachea, bronchus and lung diseases.
Features: less blood volume during operation, less postoperative complications and quick recovery. Uses: It has the functions of phacoemulsification, suction, irrigation, ultrasonic cutting to stop bleeding, and ultrasonic debridement. It can help surgeons safely and accurately separate blood vessels and bile ducts, thereby greatly reducing the degree of damage to tissues, and is suitable for various operations such as hepatobiliary surgery, neurosurgery, and endoscopic surgery.
5. Great saphenous vein rotary cutter type of scalpel
Features: The operation does not require multiple incisions, and the trauma is small. Uses: Indications for great saphenous varicose veins. During the operation, the rotary cutter enters the subcutaneous calf through a 3 to 4 mm puncture point, smashes the branches of the varicose and sucks away the varicose vein mass, and then uses a laser guide wire to penetrate the trunk of the great saphenous vein for targeted treatment. In this way, the operation time is short, the trauma is small, the patient's pain is small, and the hospitalization time is short.
6. Surgical scissors of the type of scalpel
Features: Economical and durable. Uses: Play a shearing role in surgery. Surgical scissors can be divided into wire scissors and tissue scissors. The wire scissors are straight and the tissue scissors are curved. Thread scissors are generally used for surgical sutures, and tissue scissors are generally used to separate deep tissue. Compared with foreign surgical scissors, Chinese surgical scissors are more economical and practical.
These are the types of scalpels that doctors often use during surgery. Through the above, it is not difficult to find that the shapes and shapes of these types of scalpels are different, and each has its own merits. Different symptoms require different scalpels. However, it should be reminded that no matter what kind of scalpel is used, the scalpel must be strictly sterilized before use to avoid bacterial infection of the operation and ensure the safety of the operation.
