DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] like Figure 1 to Figure 4 As shown, a storage and shearing device for an orthodontic push spring comprises an outer cylinder 1, an inner cylinder 2 is arranged inside the outer cylinder 1, a movable connecting cylinder 3 is arranged inside the inner cylinder 2, one end of the connecting cylinder 3 is used to connect to an orthodontic push spring 4, and the orthodontic push spring 4 is stored in the inner cylinder 2 when not in use; a knob 5 is provided on the top of the outer cylinder 1, one end of the knob 5 extends into the inner cylinder 2 and is connected to the other end of the connecting cylinder 3 and controls the connecting cylinder 3, and a shearing assembly is provided at the port of the outer cylinder 1 away from one end of the knob 5, and the shearing assembly is used to cut off the orthodontic push spring 4 extending from the inner cylinder.

[0025] The storage and scissoring device for the orthodontic push spring integrates the functions of storage and cutting, which can help doctors to more conveniently access the orthodontic push spring and quickly cut it to the required length, while ensuring the cleanliness and hygiene of the orthodontic push spring, which will significantly improve the efficiency and safety of orthodontic treatment.

[0026] The setting of the inner cylinder 2 can axially accommodate the orthodontic push spring 4 and the connecting cylinder 3, ensuring that the orthodontic push spring 4 will not be entangled or deformed during storage. The doctor can easily access the orthodontic push spring 4, which greatly reduces the time for arranging and taking the orthodontic push spring, and improves the efficiency of clinical operation. The inner cylinder 2 can also play a limiting and guiding role. During the axial movement of the connecting cylinder 3, the orthodontic push spring 4 can also be driven to move axially for easy access. The inner cylinder 2 and the outer cylinder 1 can be two parts connected together in a sleeve, and both the inner cylinder and the outer cylinder have thick walls; or it can also be a cylinder with an axial through hole in the middle, the middle forming an inner cylinder, and the outer cylinder on the outside, and some cavities are left between the outer cylinder and the inner cylinder to install other parts.

[0027] The setting of the knob 5 is convenient for operation. Not only can the knob 5 be used to drive the connecting cylinder 3 to move and push out the orthodontic push spring 4, but the length of the orthodontic push spring 4 pushed out can also be controlled according to the operation of the knob 5 to meet different operation requirements and improve the accuracy of treatment.

[0028] The shearing assembly is integrated at the outlet of the orthodontic push spring. The doctor does not need to prepare scissors when using it. The orthodontic push spring can be automatically cut by pressing a button, which simplifies the operation process and improves the convenience of operation. The outer cylinder is arranged to facilitate holding the entire device and protect the internal structure at the same time.

[0029] The scissors storage device can effectively reduce the contact between the orthodontic push spring 4 and the external environment, avoiding the contamination problems that may be caused during the use process, meeting the requirements of hospital infection control, and ensuring cleanliness and hygiene during use.

[0030] The storage scissors device can also continuously replenish new orthodontic push springs. When a whole section of orthodontic push spring is used up, a new orthodontic push spring can be conveniently replenished, ensuring that the device can be used for a long time, is easy to operate and has low maintenance costs.

[0031] Furthermore, the knob 5 includes a knob head 501 and a knob rod 502 connected to the knob head 501, the knob head 501 is located at the end of the outer tube 1, and the knob rod 502 extends into the inner tube 2; the knob rod 502 is threadedly connected to the connecting cylinder 3.

[0032] The knob rod 502 is arranged to be connected to the connecting cylinder 3 in the inner tube, and the knob head 501 is always located at the upper end of the outer tube to rotate and output the wire.

[0033] In some embodiments, in order to increase the tightness of the fit between the knob head 501 and the outer tube 1, corresponding annular shallow grooves are respectively provided on the lower end surface of the knob head 501 and the upper end surface of the outer tube 1, and magnets are respectively pasted or embedded in the shallow grooves, which can be the fit of magnets and magnets, or the fit of magnets and ferromagnetic metals. In this way, the knob head and the outer tube can be sucked together by magnetic force, but the relative rotational movement between the two can be not affected, because it is difficult for the two magnetically attracted parts to be separated, but it is very simple to rotate and slide.

[0034] Furthermore, each time the knob 5 rotates one circle, the connecting cylinder 3 pushes the orthodontic push spring 4 to move axially by 1 to 5 mm.

[0035] In some embodiments, in order to know the length of the orthodontic push spring 4 pushed out by rotation, a circumferential scale can be set on the outer circumference of the outer tube 1 near the knob head 501, and an indicator mark can be set on the knob head 501. By associating the number of rotations with the axial movement distance of the connecting cylinder 3, the length of the orthodontic push spring 4 pushed out in the rotation state can be known. For example, if the knob head rotates 1 circle, 2 circles, and 3 circles, the orthodontic push spring is pushed out by 5mm, 10mm, and 15mm respectively. If you want to push out a 1mm orthodontic push spring, you can only rotate the knob head 1 / 5 circle. For easy identification, the circumferential scale can be installed with a large scale mark every 1 / 5 circle, and small scale marks are set between the large scale marks, so that it is easy to use.

[0036] Furthermore, the knob rod 502 is a hollow cylinder, the inner circumference of which is provided with an internal thread and is connected to the external thread on the outer circumference of the connecting cylinder 3; or, the outer circumference of the knob rod 502 is provided with an external thread, the connecting cylinder 3 is axially provided with a connecting hole with an internal thread, and the knob rod 502 is connected to the connecting hole.

[0037] This connection method using internal and external threads is relatively simple. Since the position of the knob is relatively fixed, the hollow cylinder is confined within the inner tube. When the knob is rotated, the hollow cylinder can be moved downward or upward, thereby achieving the pushing of the orthodontic push spring.

[0038] Furthermore, a spring connection hole 9 is provided at the end of the connecting cylinder 3, and the spring connection hole 9 is connected to the orthodontic push spring 4, and the connection is simple and convenient. A hook portion can also be provided at the end of the orthodontic push spring, and the hook portion hooks the spring connection hole and closes the loop, so that the orthodontic push spring can be reliably connected. When the orthodontic push spring in the inner cylinder is used up, continue to rotate the knob to expose the lower end of the connecting cylinder from the inner cylinder and the outer cylinder, so that the orthodontic push spring can be easily replaced. The inner diameter wall of the inner cylinder has a slightly larger ring diameter of the orthodontic push spring, which is convenient for its loading and pushing out.

[0039] In some embodiments, a limit slip ring 8 is provided at the end of the connecting cylinder 3, the outer diameter of the connecting cylinder 3 is smaller than the inner diameter of the inner cylinder 2, and the outer diameter of the limit slip ring 8 is adapted to the inner diameter of the inner cylinder 2. Such a setting can not only prevent the connecting cylinder 3 from being completely screwed into the knob rod 502 during the rotation process, but also form a sliding contact surface with the inner cylinder 2, thereby improving the stability of the up and down sliding and reducing the shaking of the two. At this time, the spring connection hole 9 can be set on the limit slip ring 8 to connect the orthodontic push spring 4.

[0040] Furthermore, the center axis of the knob 5 is coaxially arranged with the center axes of the inner tube and the connecting cylinder.

[0041] Furthermore, the shearing assembly includes a pair of shearing knives 7 that are offset up and down, and the shearing knives 7 are connected to the shearing buttons 6 arranged on the outside of the outer cylinder 1 through driving members; a knife hole for the shearing knife 7 to pass through is provided between the lower end of the inner cylinder 2 and the lower end of the outer cylinder 1, or a knife hole for connecting the shearing knife 7 is provided at a position near the lower end of the inner cylinder 2.

[0042] The pair of shear knives 7 can pass through the knife hole to shear the middle orthodontic push spring 4. During the shearing process, only a pair of shear buttons 6 need to be pressed. The whole process is fast, convenient, time-saving and labor-saving. During the whole operation process, there is no cross-contact between the orthodontic push spring and the outside world, ensuring that the orthodontic push spring is clean.

[0043] Furthermore, the pair of shear knives 7 are crescent-shaped blades, which are arranged radially, with the cutting edges of the crescent-shaped blades facing inward. In the process of the two approaching each other, the pair of cutting edges can easily cut the orthodontic push spring. The pair of crescent-shaped blades can be arranged parallel to each other, and can be closed or partially overlapped during shearing, which is conducive to providing appropriate shearing force for shearing.

[0044] Furthermore, the driving member is a push-pull rod or a labor-saving multi-link connecting the shear knife and the shear button.

[0045] In some embodiments, the shear knife 7 and the shear button 6 are directly connected by a push-pull rod, and the shear button 6 is outside the outer cylinder. The push-pull rod passes through the outer cylinder 1 and is connected to the shear button 6. The shear knife 7 can be controlled by pressing the shear button 6. A reset spring can be provided on the push-pull rod to reset the shear button, and the reset spring is located between the inner cylinder and the outer cylinder.

[0046] In other embodiments, Figure 5 As shown, the push-pull rod can be electric or pneumatic, that is, a miniature electric push rod 10 or pneumatic push rod is set between the inner tube 2 and the outer tube 1, and the electric push rod 10 and the pneumatic push rod are installed on the inner wall of the outer tube 1 through a connecting frame. The output end of the electric push rod 10 or the pneumatic push rod is connected to the shear knife 7, and a shear button 6 electrically connected to the electric push rod 10 or the pneumatic push rod is set on the outer wall of the outer tube 1. Pressing the shear button 6 can trigger the electric push rod 10 or the pneumatic push rod to push the shear knife to perform a shearing operation. This control method does not require manual application of shearing force and is more convenient. A battery compartment can be set inside the outer tube 1, and a rechargeable lithium battery is set in the battery compartment to power the air pump of the electric push rod or the pneumatic push rod.

[0047] In other embodiments, Figure 6 As shown, the labor-saving multi-link 11 connected to the shear button 6 is a labor-saving lever, which can easily cut the orthodontic push spring 4. The fulcrum of the labor-saving multi-link 11 is a small round rod 12, which passes through the small round hole at the fulcrum of the labor-saving multi-link 11 and is connected to the support cross bar 13 in the outer tube 1. The support cross bar 13 is arranged between the outer wall of the inner tube 2 and the inner wall of the outer tube 1, which can support the small round rod 12 and enhance the connection strength between the inner tube and the outer tube. The outer wall of the outer tube 1 is provided with an arc-shaped clearance groove 14 to facilitate the movement of the labor-saving multi-link 11. This is just one form of labor-saving lever, and it can also be a labor-saving lever with other structures, such as the setting of multiple fulcrums and multiple sections of levers.
