Description

Technical Field

[0001] The utility model relates to a metal support cleaning device, which is mainly used for cleaning the metal support. Background Art

[0002] In the past decade, metal stents have been widely used in human medical treatment, and have undergone improvements from spiral coil structures to grid-like braided structures, laser-cut tubular structures, from bare stents to polymer coatings or polymer tube wrappings, from shape memory effect types to superelastic self-expansion types, and from long-term implantation to short-term implantation and recyclability.

[0003] The materials of the metal stents involved are also various, among which nickel-titanium alloy, cobalt-chromium alloy, stainless steel, etc. are the most common. With the widespread use of metal stents, the requirements for stents are becoming more and more stringent. Common metal stents usually have an overall removal amount, which can be achieved after cleaning pre-treatment and polishing; however, some metal stents have different size requirements for different parts of a stent, and some require the removal amount at both ends to be slightly more than the removal amount in the middle. For guidewires and catheters with low requirements for the length of the cleaning part, the normal cleaning process can meet the requirements, and the metal stent polishing can also be achieved. However, some metal stents require the removal amount at both ends to be far more than the removal amount in the middle, and the overall length is short and the length of the cleaning area is very small. This cannot be achieved by polishing alone, because excessive removal will cause the transition zone to break, and it is necessary to clean to meet the requirements before overall polishing.

[0004] However, currently, the normal cleaning of metal stents is performed by holding a single stent by a person or clamping a single stent so that the cleaning area is immersed in a solution, so that each metal stent cannot be fully cleaned, the cleaning area cannot be accurately controlled, and multiple stents cannot be cleaned. Summary of the invention

[0005] In order to overcome the above technical problems, the utility model provides a metal bracket cleaning device which can be cleaned conveniently and has good cleaning effect.

[0006] The purpose of the utility model is achieved in this way:

[0007] A novel metal bracket cleaning device comprises a chuck structure consisting of an upper fixed plate, a movable plate and a lower fixed plate, wherein the movable plate is located between the upper fixed plate and the lower fixed plate, screw holes are provided on the upper fixed plate and the lower fixed plate, and the upper fixed plate and the lower fixed plate are fixed after the screws are passed through, spring grooves are provided on the top and bottom of the movable plate, a plurality of springs are installed in the spring grooves, and the metal bracket is fixed in the chuck structure consisting of the upper fixed plate, the movable plate and the lower fixed plate by means of the springs, and the chuck structure is placed in a hollow floating member, and the hollow floating member is placed in a solution tank, a cleaning solution is poured into the solution tank, and the chuck structure is located at the center of the hollow floating member.

[0008] A workpiece area is formed between the spring and the upper fixing plate and the lower fixing plate.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] This type of metal bracket cleaning device fixes the metal bracket through the upper and lower fixed plates, movable plates and the elastic force of the spring. The clamping is fast and stable, and multiple brackets can be cleaned at one time. The large number of cleanings can make each metal bracket be fully cleaned and the cleaning area can be accurately controlled. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] See also Figures 1 to 3 The utility model relates to a metal bracket cleaning device, which includes a chuck structure composed of an upper fixed plate 4, a movable plate 5 and a lower fixed plate 6, the movable plate 5 is located between the upper fixed plate 4 and the lower fixed plate 6, screw holes 1 are provided on the upper fixed plate 4 and the lower fixed plate 6, and the upper fixed plate 4 and the lower fixed plate 6 are fixed after the screws pass through, and spring grooves 2 are provided on the top and bottom of the movable plate 5, and a plurality of springs are installed in the spring grooves 2. Before the springs are fully compressed, they can resist the upper fixed plate 4 and the lower fixed plate 6, and a workpiece area 3 is formed between the springs and the upper fixed plate 4 and the lower fixed plate 6 for placing the metal bracket to be cleaned. After the worker compresses the spring and puts the metal bracket into the workpiece area 3, the spring is used to fix it in the chuck structure composed of the upper fixed plate 4, the movable plate 5 and the lower fixed plate 6.

[0016] The chuck structure is placed in a hollow floating member 7, and the hollow floating member 7 is placed in a solution tank 8. A cleaning solution 9 is poured into the solution tank 8. The hollow floating member 7 has a sinking height in the cleaning solution 9, and the chuck structure is located at the center of the hollow floating member 7. Under the limitation of the hollow floating member 7, it can move in a small range, and the metal bracket to be cleaned can be completely immersed in the clear solution 9, and then the cleaning is completed.
