Description

Technical Field

[0001] The utility model specifically relates to a lens fixing device. Background Art

[0002] Laparoscopic surgery refers to the discipline of completing surgical examinations or operations with the assistance of laparoscopes. The laparoscope used is a rod-shaped optical scope, which is divided into an inspection scope and an operation scope. It has different names depending on the location of the laparoscope. For example, the one inserted into the abdominal cavity is called a laparoscope, and the one inserted into the thyroid gland is called a thyroid laparoscope. During the use of the laparoscope, in order to reduce the labor intensity of medical staff, the laparoscope will be fixed in the inspection area through a fixing device for use, so as to achieve the purpose of saving labor.

[0003] For example, the Chinese utility model patent with patent number 202020175202.0 provides a laparoscope lens fixing device, wherein a first locking mechanism is provided between the support rod and the plug-in portion to lock the two in at least two working positions, a second locking mechanism is provided between the support rod and the fixed clamp to lock the two in at least two working positions, and a clamping mechanism for clamping the laparoscope lens is provided on the fixed clamp.

[0037] When in use, the fixed plate 202 is fixed in the surgical area, which can be on the surgical bed, or on a surgical hook or other position. After the position of the fixed plate 202 is fixed, the laparoscope can be fixed by passing it through the fixing seat 102, and the laparoscope can be inserted into the patient's body for inspection. If the angle of the laparoscope needs to be adjusted, the laparoscope or the mounting plate 101 can be pulled to move the laparoscope. During the movement of the mounting plate 101, the pull rope 302 is pulled to drive the reel 301 to rotate, thereby driving the constant force spring 303 to deform through the movement of the reel 301. When the laparoscope is no longer needed, the reel 301 can be controlled to reset under the reset capacity of the constant force spring 303, so that the pull rope 302 is retracted to drive the mounting plate 101 and the laparoscope to reset.

[0042] The threaded knob 403 can be driven to slide along its axis by rotating the threaded knob 403, thereby driving the drive shaft 404 to move along the axis of the threaded knob 403. During the movement, the drive shaft 404 drives the fixed plate 202 to rotate along the hinge point between it and the fixed frame 401 through the sliding connection with the sliding frame 203, so that the initial angle of the fixed seat 102 can be adjusted, thereby adjusting the initial angle of the laparoscope to facilitate the use of the laparoscope.

[0043] Specific usage and beneficial effects of the utility model:

[0044] When the device is in use, the laparoscope is fixed in the fixing seat 102, and the fixing plate 202 is hoisted in the operating area through the cooperation of the fixing frame 401 and the fixing knob 402, so that the medical staff does not need to hold the laparoscope for a long time to use it, which effectively reduces the labor intensity of the medical staff when using the laparoscope, and when it is necessary to change the observation position, the mounting plate 101 can be manually pulled out to move the laparoscope, which is convenient for using the laparoscope to perform multi-directional examinations on the patient. During the process of pulling out the mounting plate 101, the winding shaft 301 is driven to rotate by the pull rope 302 to deform the constant force spring 303, and the mounting plate 101 can be loosened and the pull rope 302 can be retracted under the resetting action of the constant force spring 303, so that the mounting plate 101 is reset and the laparoscope is reset, so that the laparoscope can be changed at any time during the laparoscopic examination, and the physical strength of the medical staff can be effectively saved.
