AI Technical Summary
Existing traction devices for gastroenterology endoscopy are prone to colliding with the patient's body during clamping, causing discomfort. Furthermore, the large range of rotation of the clamp may also lead to patient discomfort.
An auxiliary traction device for gastroenterology endoscopy was designed. The rotation of the transmission ring pushes the transmission frame, which drives the rollers to move laterally. The rollers squeeze the transmission plate, and the transmission plate drives the first clamping piece to slide longitudinally. The clamping piece slides in the traction tube without rotating, thus avoiding collision with the patient's body.
This effectively avoids collisions between the device and the patient's body, improving the safety and comfort of the operation and reducing the risk of surgical complications.

The first clamping piece 3 can move toward the second clamping piece 4 to clamp the clamping position and assist in traction of the endoscope.
[0025] Among them, such as Figure 1 , Figure 2 and Figure 3 As shown, a second sliding rail 16 is provided at one end of the first clamping piece 3 facing the traction tube 1. The first clamping piece 3 is embedded in the second sliding rail 16 and slidably connected to the second sliding rail 16. When the first clamping piece 3 moves toward the second clamping piece 4, the first clamping piece 3 will slide along the second sliding rail 16.
