Description

A magnetically controlled detachable minimally invasive hemostatic forceps

technical field

The invention relates to a minimally invasive hemostatic forceps, in particular to a magnetically controlled detachable minimally invasive hemostatic forceps.

Background technique

With the development of modern science and technology, the medical level is also constantly improving. In order to allow patients to have an easier operation process and faster and better recovery, the concept of "minimally invasive surgery" has emerged and developed rapidly. Compared with traditional surgery, minimally invasive surgery has the advantages of small wound, less bleeding, less pain, and faster recovery, which reduces the pain of patients. Due to the difficulty of laparotomy, susceptibility to infection and poor postoperative recovery, laparoscopic surgery, one of the main operations of minimally invasive surgery, is widely used in modern medicine. The so-called laparoscopic surgery is to make several small incisions with a diameter of 5 to 12 mm in different parts of the abdomen. Through these small incisions, camera lenses and various special surgical instruments are inserted, and various intra-abdominal images captured by the cameras inserted into the abdominal cavity are inserted. The images of the organs are transmitted to the TV screen, and the surgeon observes the images and performs operations outside the body with various surgical instruments to complete the operation.

Although laparoscopic surgery has the advantages of small wounds, intuitive effects, and less pelvic adhesions, it also has disadvantages such as small operating space, high difficulty, lack of cooperation from doctors, and insufficient equipment. In a limited operating space, too many surgical instruments will inevitably interfere with the doctor's vision, and the doctor may use multiple hemostatic forceps during the use of surgical instruments, especially in severe bleeding environments , then the mutual collision of surgical instruments will cause unnecessary damage to the patient's tissues or organs. In order to solve some surgical defects, it is necessary to design and optimize the structure of laparoscopic surgical forceps from the perspective of instruments.
