Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medical endoscope lens fixing device. Background Art

[0002] In minimally invasive laparoscopic surgery, the surgeon needs to assist in fixing the laparoscopic lens. For surgeries with special angles and body positions, the operation time is long, and the surgeon holding the lens needs to maintain good physical strength, that is, to maintain the same posture without changing, in order to ensure that the surgical field is visible. However, in the case of insufficient manpower, the surgeon needs to temporarily arrange an intern to assist in holding the lens. However, the intern has not received training in laparoscopic surgery cooperation from practicing doctors and cannot effectively cooperate in the operation, which often causes the surgeon to be distracted from guidance or even assist in placement, ultimately affecting the smooth progress of the operation, and bringing a series of surgical risks and complications to the surgical patient, such as prolonged operation time, increased use of anesthetic drugs, and increased risk of surgical infection. In addition, for special surgeries (such as laparoscopic adrenal tumor removal in the lateral position), the surgeon and the assistant stand on the same side, resulting in less space for the assistant. As the operation time is long, the lens will inevitably shake, and the risk of accidental injury to delicate operations such as free blood vessels during the operation will increase sharply.
