Description
Technical Field
The invention belongs to the technical field of hard mirrors and soft mirrors of medical equipment, and particularly relates to a double-forceps-channel single-hole bendable laparoscope system.
Background
Modern surgery is continually evolving and optimizing with advances in technology, increased medical diagnosis and treatment levels, and patient health needs. Minimally invasive surgery, which is a very vigorous development, is the inevitable result of the continual exploration of surgeons for the surgical principles of "reduced trauma, pain relief" and the patient's requirements for "painless, scarless, small wounds" of the operation.
Laparoscopic techniques, which arose in the nineties of the last century, led to surgery in the minimally invasive era. From the first example of laparoscopic cholecystectomy in the world to the introduction and integration of a minimally invasive surgical robotic platform, the development of minimally invasive surgery is rapid, and the traditional various open-abdominal operations have been switched to traditional laparoscopic and single Kong Fuqiang-scope operations. However, the single-port laparoscopic technique does not change the surgical habit of the surgeon rapidly as compared with the traditional laparoscopic technique, because all instruments occupy the space of a unique poking card at the same time in the operation, which causes mutual interference of the instruments, is difficult to form an operation triangle, and has great operation difficulty and long learning curve; meanwhile, the diameter of a single incision is large, and practical minimally invasive benefits are limited. In this regard, related practitioners have attempted to increase the operability of single-port laparoscopic techniques by bending instruments, but single-port laparoscopic techniques have remained difficult to popularize due to the drawbacks of the hard rod instruments themselves, and the fact that certain instruments can only perform certain operations.
Endoscope technology has advanced the medical industry over time, and is a tube equipped with a light source that can be passed orally into the stomach or through other natural orifices to the corresponding site in the body. The lesions that cannot be seen by X-rays can be seen with an endoscope, so that it is very useful for doctors. For example, a physician may view ulcers or tumors in the stomach via a gastroscope, thereby developing an optimal treatment regimen. The endoscope used clinically is usually a soft endoscope, the external diameter of the endoscope is smaller, and is generally about 10mm, the endoscope body is softer and more flexible, and the endoscope can be bent in a large scale to complete related operations. At present, means for solving surgical diseases under an endoscope are also continuously developed. However, the soft and flexible nature of the device also results in insufficient rigidity, difficulty in achieving satisfactory positioning in the abdominal cavity, and fewer procedures to perform.
