Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a damped endoscope carousel structure comprising: the handle control part comprises a handle control part main body 10, a rotary table 20, a swing arm 30, a single upper steel wire 40, a single lower steel wire 50 and an adjusting plate 60, wherein a rotary shaft hole 11 is formed in the handle control part main body 10, the swing arm 30 extends into the handle control part main body 10 through the rotary shaft hole 11, and the rotary table 20 is arranged at the tail end of the extending part of the swing arm 30 through a rotary table fixing screw 70; the adjusting plates 60 are provided with steel wire holes 61, and the two adjusting plates 60 are arranged on the rotary plate 20 through adjusting plate fixing screws 80, wherein the initial stage of the adjusting plate fixing screws 80 is a pre-locking adjusting plate. The single upper wire 40 and the single lower wire 50 initially pass through wire holes 61 in their respective discs 60. After one end of the single upper wire 40 and one end of the single lower wire 50 are reserved to a proper length through the wire hole 61, the ends are knotted, and then welded at the knotted positions to form the wire bonding head 90, the wire bonding head 90 being movable. When the adjusting disk 60 rotates to tighten the steel wires, the reserved lengths of the single upper steel wire 40 and the single lower steel wire 50 are gradually shortened until the steel wire welding heads 90 contact the steel wire holes 61, the single upper steel wire 40 and the single lower steel wire 50 are wound on the adjusting disk 60, and at the moment, the steel wires need to tighten the stressed steel wire welding heads 90 to play a limiting stress role. The rotary table 20 is provided with an upper wire passing groove 21 and a lower wire passing groove 22, respectively, and the other ends of the single upper wire 40 and the single lower wire 50 are wound on the rotary table 20 through the upper wire passing groove 21 and the lower wire passing groove 22, respectively (the other ends of the single upper wire 40 and the single lower wire 50 are both connected with the bending part of the end of the insertion part connected with the control part of the handle control part main body 10, and the adjustment range of changing the angle of the bending part is realized by tensioning the single upper wire 40 and the single lower wire 50, which is not shown in the figure in the conventional technical scheme). The swing arm 30 is rotated, and the swing arm 30 pulls the single upper wire 40 and the single lower wire 50 through the turn table 20, thereby changing the bending angle of the bending portion.

When the fastening screw on the adjusting disk 60 is loosened, the adjusting disk 60 rotates on the turntable 20, the tension of the single upper steel wire 40 and the single lower steel wire 50 can be adjusted, and the angle range of the bending part at the tail end of the insertion part is adjusted, so that the adjusting device is convenient and quick. If the single upper steel wire 40 and the single lower steel wire 50 need to be reworked, the quick reworking adjustment can be realized only by disassembling the side cover, and the method is simple and convenient.

The damping type endoscope turntable structure further comprises a pressure spring 100, a spring placing groove 12 is formed in the handle control part main body 10, the pressure spring 100 is placed in the spring placing groove 12, and the top end of the pressure spring 100 abuts against the turntable 20. The turntable 20 compresses the compression spring 100 while locking, and the compression spring 100 provides a reaction elastic force to resist the turntable 20, so as to achieve a damping effect, and the turntable 20 can be stopped at any position.

The damping type endoscope turntable structure further comprises an O-shaped ring 110, wherein the O-shaped ring 110 is sleeved on the swing arm 30 and is positioned between the handle control part main body 10 and the swing arm 30. The O-ring 110 can prevent external liquid from entering the inside of the handle control portion body 10 through the gap between the handle control portion body 10 and the swing arm 30.

The damping type endoscope turntable structure further comprises a decoration piece 120, a decoration piece groove 31 is formed in the swing arm 30, and the decoration piece 120 is installed in the decoration piece groove 31. Because the repeated endoscope is subjected to cleaning, disinfection or sterilization treatment after being used, the interior of the decoration groove 31 is not thoroughly cleaned, disinfected or sterilized, which easily causes bacteria to breed and cross infection of patients, so that the decoration 120 has a non-traditional decoration function and is used for protecting the decoration groove 31.
