[0002] Digestive endoscope is a group of equipment for diagnosing and treating digestive system diseases by directly obtaining image through digestive tract or obtaining ultrasonic or X-ray image of digestive tract and digestive organ through ultrasonic or X-ray equipment attached to the device. The operation of digestive endoscope usually requires the cooperation of endoscopist's left and right hands: the endoscopist operates the endoscope operating part with the left hand to control functions such as bending angle, water supply / negative pressure supply, image processing function remote control, etc.; the endoscopist operates the endoscope insertion part with the right hand to control functions such as advancing, retreating, rotating, fixing, etc. of the endoscope insertion part. The existing digestive endoscope products have deficiencies in human engineering design; when performing actual treatment operation, the endoscopist and the surgical assistant often need to cooperate with each other to complete the operation of the treatment instrument: the surgical assistant operates the handle of the treatment instrument to control the extension, retraction, rotation, etc. of the instrument; the endoscopist also needs to control the treatment instrument with the right hand, and the treatment instrument enters the human body through the digestive endoscope instrument channel; the endoscopist adjusts the extension distance of the instrument under the digestive endoscope image according to the position of the lesion; when adjusting, the endoscopist has to release the digestive endoscope insertion part with the right hand, at this time, the digestive endoscope insertion part changes its position in the human body due to the reaction force or the elastic recovery of the digestive endoscope insertion part itself, and even has the risk of slipping out of the human body. Therefore, in order to better ensure the treatment quality, it is necessary to keep the position of the endoscope in the human body unchanged and to adjust the treatment instrument at the same time, which requires the endoscopist to adjust back and forth between the insertion part and the treatment instrument with the right hand, in addition, when facing particularly difficult surgical treatment positions, the endoscopist often cannot complete both keeping the position of the endoscope in the human body unchanged and adjusting the treatment instrument, which requires a surgical assistant who cooperates with the endoscopist to complete the action of adjusting the treatment instrument.

The upper jaw 321 is fixed on the inner wall of the top of the shell 330. The lower jaw 322 is connected to the telescopic driver 410 of the control assembly 400. The distance between the lower jaw 322 and the upper jaw 321 can be controlled by the telescopic driver 410. Thus, the tightness of the endoscope clamping can be adjusted to adapt to the diameter of the insertion part of the endoscope of different sizes.

The upper jaw 321 and the lower jaw 322 are embedded with a plurality of rotatable balls on the opposite sides. The balls are in extrusion contact with the outer surface of the insertion part of the digestive endoscope. When an external force is applied to make the insertion part of the digestive endoscope rotate or move, the balls will rotate in the opposite direction under the action of the friction force of the insertion part, so that the insertion part of the digestive endoscope can rotate or move in the inner cavity of the clamp. When the insertion part and the balls are kept relatively stationary, the insertion part of the digestive endoscope is clamped and fixed.

[0024] The control assembly 400 can adjust the tightness of the endoscope clamp of the clamping assembly 300. The control assembly 400 includes a telescopic driver 410 and a double foot switch 420. The double foot switch 420 is connected to the telescopic driver 410 through a conductive wire bundle.

[0025] Further, the double foot switch 420 is provided with a switch for controlling the forward extension of the telescopic driver 410 and a switch for controlling the backward retraction of the telescopic driver 410. The forward extension switch makes the lower jaw 322 close to the upper jaw 321, i.e. tightens the endoscope clamping. The backward retraction switch makes the lower jaw 322 away from the upper jaw 321, i.e. loosens the endoscope clamping.

[0026] The system can use a battery mobile power supply as a power supply. The battery mobile power supply can be replaceably placed in the battery box inside the double foot switch 420. The double foot switch 420 can be arbitrarily moved and adjusted in position. In addition, the system can also use a variable voltage conversion socket connected to the public power grid as a power supply. The system has the advantage of continuous endurance.
