Autoclavable adapters and endoscope systems

technical field

The present disclosure relates to an adaptor and an endoscope system that can be sterilized at high temperature and autoclave.

Background technique

Considering the conditions of ergonomics and hand comfort, the lens barrel knob is The outer wall of 112 is designed with a special rounded concave-convex shape to increase the comfort of medical staff when using, and the inner wall of the lens barrel knob 112 is designed as a circular barrel that runs through the front and rear, so that it can be sleeved on the outer lens barrel 102.

According to an embodiment of the present disclosure, it can be configured to provide non-contact power through a magnetic structure, and adjust the internal optical lens assembly 101 to achieve the purpose of adjusting image clarity.

Specifically, magnetic attraction is formed between the plurality of circular magnets on the inner wall of the lens barrel knob 112 and the plurality of circular magnets on the cylindrical wall of the rotating barrel 108, so that when the medical staff rotates the lens barrel knob 112, due to Due to the action of magnetic attraction, the rotating cylinder 108 inside the sealed space will also rotate, which drives the movement of the optical lens assembly. Since the supporting cylinder 107 has a specific track groove, the optical lens assembly 101 can be According to the designer's design intention, the adapter 100 moves on the set trajectory, so as to achieve the function of the adapter 100 to adjust the imaging

FIG. 4 shows the distribution of magnetic field lines of the magnet 1121 and the magnet 1081 . The following two solutions can be adopted for the distribution of magnetic field lines of the magnet 1121 embedded on the inner wall of the lens barrel knob 112 and the magnet 1081 embedded on the inner wall of the rotating cylinder 108 . Scheme 1, the circular magnet 1121 embedded in the inner wall of the lens barrel knob 112 can have the N pole outside the inner S pole, and the circular magnet 1081 embedded in the inner wall of the rotating cylinder 108 must have the N pole and the inner S pole outside. In the second solution, the circular magnet 1121 embedded in the inner wall of the lens barrel knob 112 can have the S pole inside and the N pole outside. It should be noted that the above-mentioned "inside" and "outside" are relative to the overall structure of the adapter, and those close to the optical lens assembly 101 are inside, and those far away from the optical lens assembly 101 are outside. In this way, a magnetic attraction force can be formed between the lens barrel knob 112 and the rotating lens barrel 108 instead of a repulsive force or a disordered magnetic field force. This design can be used for each of the two magnets in a one-to-one correspondence.

The above-mentioned magnetic attraction structure is combined with the sealed space formed by welding the outer lens barrel and the front and rear end covers to form the main body of the high temperature and autoclave sterilizable adapter structure of the present disclosure. The movement of the optical lens assembly can be adjusted, and the inner optical lens assembly can be protected so that it will not be damaged during high temperature and high pressure steam sterilization.
