Problems solved by technology

[0004] The end of the existing lens is mostly in the shape of a truncated cone, but in the current operation process, there is no device to fix the lens, and other personnel need to hold the lens all the time, and when the operation time is long, the operator holding the lens will Arm soreness and other situations not only cause fatigue to the operator, but also hand-holding the lens may easily cause the lens to shake, which is not conducive to the smooth progress of the operation

Abstract

The invention belongs to the field of instruments for visual or photographing examination of cavities and tubes of the human body and particularly discloses a device for fixing a lens in an endoscopesurgery. The device comprises an isolation cover, a fixing ring and a connecting portion, wherein one end of the isolation cover is connected with the fixing ring, the fixing ring is detachably connected with the connecting portion, the inner side of the connecting portion is provided with a fixing structure for fixing a lens, the fixing structure comprises a connecting rod and a fixing part, thefixing part comprises multiple connecting units, the multiple connecting units are sequentially connected to form a ring shape, each connecting unit includes two connecting rods, the middles of the two connecting rods are hinged, and the two ends of each connecting rod are both connected with the inner side of the connecting portion and one connecting unit. The device can fix the lens when a medical worker performs the endoscope surgery and is good in fixing effect, and the adverse influence of shaking of the lens on the endoscope surgery is avoided.

Description

technical field [0001] The invention belongs to the field of instruments for visually or photographically inspecting cavities or tubes of a human body, and specifically discloses a device for fixing a lens in laparoscopic surgery. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. Taking laparoscopic surgery as an example, the method of laparoscopic surgery is to make three small incisions of 1 cm on the patient's waist to form a tube-shaped working channel called "trocar". Special lengthened surgical instruments complete the same steps as open surgery under TV monitoring to achieve the same surgical effect. [0003] Because the diameter of the tubular working channel of the "trocar" is small, the doctor cannot directly observe during the operation. At this time, the lens needs to be inserted into the "trocar" to transmit the situation in the patient'...
