Description

Technical Field

[0001] The utility model relates to the technical field of ligation devices, in particular to a ligation device for a digestive endoscope. Background Art

[0002] According to the patent authorization announcement number: CN217365967U, a gastroenterology endoscope ligation device is proposed. The utility model discloses a gastroenterology endoscope ligation device, including an endoscope controller, a ligation device, an adjustment knob and a liquid crystal display panel. The ligation device is installed on the top of the endoscope controller, and the adjustment knob and the liquid crystal display panel are installed on the surface of the endoscope controller. The upper and lower ends of the liquid crystal display panel are provided with slide grooves, and sliders are installed in the slide grooves. Through the mutual cooperation of the slide grooves, sliders, fixing seats, mounting grooves, mounting blocks, cleaning blocks and push rods, the cleaning block can be driven by the force of the push rod to drive the two groups of sliders to slide along the slide grooves. When the cleaning block moves to the surface of the liquid crystal display panel, as the cleaning block continues to slide, the cleaning block can quickly clean the dust or stains on the surface of the liquid crystal display panel, ensuring the clarity of the liquid crystal display panel and facilitating the medical staff to accurately observe the liquid crystal display panel.

[0003] However, in the process of using the ligation device in the prior art, the controller needs to be held by hand to control the ligation device. The operational stability of the ligation device depends on the stability of the controller, but the way of holding the controller by hand can easily cause the controller to fall and affect the operation. In addition, after use, the ligation device needs to be cleaned and disinfected. The ligation device is fixedly installed on the controller, which affects the sterilization dead angle and affects the subsequent use. Therefore, it is necessary to improve the prior art.
