Description

Adjustable endoscope fixing device Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an adjustable endoscope fixing device. Background Art

[0002] Minimally invasive surgery has become the main development trend of surgical treatment. Minimally invasive surgery is actually a surgery with minimal trauma. It avoids large incisions under a certain degree of medical risk, uses tiny incisions, and uses special instruments and devices. Under the monitoring of imaging instruments or the guidance of navigation technology, it reaches the lesion from the normal anatomical structure, uses various miniature manual or electric instruments and equipment, and completes the entire surgical process under visual conditions. The purpose is to achieve a surgical treatment with smaller incisions, less tissue trauma, less bleeding, higher operating precision, definite results, and faster postoperative functional recovery than traditional or standard spinal surgery.

[0003] Currently, minimally invasive spinal surgery is performed with the assistance of an endoscope. This allows doctors to perform tasks that previously required larger incisions through small incisions. During surgery, the doctor holds the endoscope in one hand and manipulates the surgical instruments with the other. The magnifying effect of the endoscope allows the doctor to more accurately and completely manipulate the instruments to treat the lesion.

[0004] However, during long operations, the doctor's arms will become tired from continuously holding the endoscope, which will reduce the stability of the endoscope's position. The mild consequence may be incomplete surgery. In severe cases, if the endoscope suddenly falls, it may press on the nerves and endanger the patient's life.
