摘要： Disclosed are an endoscope wire pulling wheel, an endoscope handle, and an endoscope. During a winding process, both ends of a pull wire are respectively distributed at two opposite sides of a winding part; then, the two ends of the pull wire are respectively correspondingly wound in the two winding grooves in opposite directions. Since the two wire winding grooves are provided with wire penetrating holes communicated with a cavity, after the pull wire is wound, the ends of the pull wire can penetrate through one wire penetrating hole to the cavity, and then penetrate through the other wire penetrating hole from the cavity; and the penetration is repeated such that the ends of the pull wire can be stably fixed on the winding part.

摘要： Disclosed are an endoscope knob brake device, an endoscope handle, and an endoscope. The endoscope knob brake device includes a fixed frame, brake members and a brake knob. The fixed frame includes an operating cavity configured for a knob mechanism to pass through. At least two sliding grooves are arranged at intervals around the operating cavity. The brake members are slidably installed in the sliding grooves in a one-to-one correspondence. The brake knob is sleeved over the fixed frame. At least two pushing portions are disposed at intervals on an inner wall of the brake knob. When the brake knob is rotated to a preset angle, the pushing portions push, in a one-to-one correspondence, the brake members to move toward the operating cavity to hold the knob mechanism tightly.

摘要： Disclosed are an endoscope knob device, an endoscope handle, and an endoscope. The endoscope knob device includes a first cable pulley defining a first perforation, a first matching portion, and a first latching portion; a second cable pulley defining a second matching portion and a second latching portion; and a first knob and a second knob which are sleeved over the first cable pulley and the second cable pulley, respectively. The first knob includes a third matching portion and a third latching portion that matches with the first latching portion. The third matching portion cooperates with the first matching portion, so that the first knob drives the first cable pulley to rotate. The second knob includes a fourth matching portion and a fourth latching portion. The fourth matching portion cooperates with the second matching portion, so that the second knob drives the second cable pulley to rotate.
