Detailed Description
In order to make the purpose, technical scheme and points of the invention more clear. The technical solution of the present invention will be described in detail below. All other technical solutions which can be obtained by a person skilled in the art without creative efforts based on the description of the present invention belong to the protection scope of the present invention.
The disposable orthodontic ligature wire twisting module based on the needle holder is structurally divided into three layers from inside to outside. In the embodiment, the rotating sleeve is disassembled for convenient assembly, and the rotating sleeve concept in the technical scheme comprises a series of static removing sleeves 5 (handheld parts) such as a rotating sleeve head 4, a rotating sleeve 9, a rotating sleeve base 6 and the like and a part of the double-spiral guide rail mandrel 1.
For the sake of better intuition, the following description will be made with the axial direction of the double-spiral guide spindle 1 as the central axis and the direction from the double-spiral guide spindle 1 to the rotating sleeve base 8 as the positive direction of the central axis.
The first layer is the innermost layer and the action is performed in a reciprocating motion along the central axis. The first layer comprises a double helix rail mandrel 1. Wherein the double-helix guide rail mandrel 1 also comprises a thumb ring 101 and a double-helix guide rail groove 102. When in operation, a thumb is sleeved into the thumb ring 101 and moves up and down to drive the double-helix guide rail mandrel 1 to reciprocate along the central shaft.
The second layer is an intermediate layer, the completed action is the rotation movement around the central shaft, and the second layer comprises a rotating sleeve head end cover 2; a ball head guide post 3; a sleeve turning head 4; a rotating sleeve base 6; a quick-release binding band 7; a quick-release base 8 and a rotary sleeve 9. The double-helix guide rail core shaft is limited by the embedding of the sleeve rotating head end cover 2 and the sleeve rotating head 4, the ball head guide pillar 3 is positioned on the inner wall of the sleeve rotating head 4, the sleeve rotating head 4 and the sleeve rotating 9 are buckled, the sleeve rotating 9 and the sleeve rotating base 6 (which can limit the static sleeve 5) are buckled and connected, and the sleeve rotating base 6 is provided with a quick-release bandage 7 and a quick-release base 8. The rotating sleeve head 4 or the rotating sleeve 9 can limit the upper end of the static sleeve 5 through the shape, so that the static sleeve 5 is prevented from being separated.
During operation, the ball head of the ball head guide post 3 is embedded in the double-spiral guide rail groove 102 of the double-spiral guide rail mandrel 1.
When a thumb is pressed along the positive direction of the central shaft, the ball guide post 3 can be limited by the rotating sleeve head 4 (the limiting position that the ball guide post 3 deforms downwards is arranged in the rotating sleeve head 4, such as a step design, see fig. 2), and the ball guide post cannot deform, so that the double-spiral guide rail groove 102 can receive the lateral force given by the ball, and the ball guide post can receive the reaction force of the double-spiral guide rail groove 102 because the double-spiral guide rail mandrel 1 is not rotatable, so that the ball guide post rotates around the central shaft, and the rotating sleeve head 4 is driven; a sleeve head end cover 2; a rotating sleeve base 6; a quick-release binding band 7; the quick-release base 8 and the rotary sleeve 9 rotate.
When the thumb pulls along the opposite direction of the central shaft, the ball head of the ball head guide post 3 does not have any limit in the rotating sleeve head 4 along the opposite direction of the central shaft, so that the ball head can deform and is separated from the double-spiral guide rail groove 102, and at the moment, the middle layer does not have any action.
The main action of non-rotation during pressing, rotation and extraction is completed through the double-spiral guide rail groove 102 and the ball guide post 3.
In the middle layer rotating process, the quick-release binding band 7 ties the hand holding ring of the needle holder 303 in advance and drives the needle holder 303 to complete the rotating action so as to complete the ligation action.
The third layer is the outermost layer, which comprises a static sleeve 5, wherein, the two sides of the static sleeve are provided with middle finger rings 501. When in operation, the middle finger and the index finger need to be hooked on the middle finger ring 501, and the outermost layer has no action and only serves as a fixing function.
