Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical devices, and in particular to a universal interface of an electrochemical decontamination device on the surface of a dental implant. Background Art
[0002] Peri-implantitis is a type of plaque-related pathological condition caused mainly by poor plaque control, which is mainly manifested by peri-implant mucosal inflammation and progressive bone loss. The primary principle of its treatment is to remove the plaque biofilm on the implant surface. At present, the surface decontamination treatment of peri-implantitis mainly involves various advanced oxidation technologies, including atmospheric pressure low-temperature plasma treatment, electrochemical decontamination, gaseous ozone therapy, photocatalysis, catalyst method, etc.; among them, the electrochemical decontamination method is to spray electrolyte solution around the implant and generate hydrogen on the implant surface under the action of ultra-low voltage of electrochemical equipment, thereby achieving physical exfoliation of the biofilm.
[0003] However, existing electrochemical decontamination equipment for implants can usually only operate on a specific type of implant. For example, Nobel Biocare has developed and marketed an electrochemical device that can be used for clinical implant surface decontamination. The connection between the nozzle of the decontamination device and the implant relies on a sponge provided in the spray section of the nozzle. When in use, the nozzle needs to be manually pressed throughout the process to make the sponge fit the upper end surface of implants with different inner diameters, so that it can be firmly connected to the implant and will not fall off. That is, if the interface of the electrochemical decontamination device itself is not pressed, it will cause poor contact due to mismatch with the implant or fall off due to inability to fix itself, thereby affecting the decontamination effect. Therefore, there is an urgent need for an interface design that does not require additional manual pressing during use and has good versatility and stability. Summary of the invention
[0004] The purpose of the present invention is to solve the shortcomings of the prior art, thereby providing a universal interface for an electrochemical decontamination device on the surface of a dental implant, comprising: At least two interface posts are arranged at the bottom of the spray end of the electrochemical decontamination device; an adjustment gap is arranged between any two adjacent interface posts; the interface post comprises a connection section fixedly connected to the spray end of the electrochemical decontamination device and a clamping section fixedly connected to the connection section; the universal interface comprises at least an unconnected state and a normal implant clamping state; In the unconnected state, any one of the interface columns is perpendicular to the lower end surface of the spray end of the electrochemical decontamination device as a whole; in the normal clamping state of the implant, each of the interface columns is inclined along the adjustment gap toward the center line of the spray end of the electrochemical decontamination device, and under the action of the reset force, the outer wall of the clamping section contacts the inner diameter of the large-opening implant.
[0005] Furthermore, the interface column and the spray end are both made of metal with good current conductivity and corrosion resistance.
[0006] Furthermore, the outer wall of the clamping section protrudes beyond the outer wall of the connecting section, and the outer wall of the clamping section and the bottom surface of the clamping section are processed with rounded corners; the outer wall of the clamping section and the outer wall of the connecting section are connected with chamfered corners.
[0007] Furthermore, the spray end is in the shape of a hollow cylinder; The outer diameter length of the spray end ranges from 1.8 mm to 4.5 mm.

The universal interface of a dental implant surface electrochemical decontamination device of the present invention comprises two interface posts symmetrically arranged on the lower end surface of the spray end of the electrochemical decontamination device, the interface posts comprising a clamping section and a connecting section, the outer wall of the clamping section protrudes beyond the outer wall of the connecting section, and an adjustment gap is provided between adjacent interface posts, the interface posts can be tilted in the direction of the adjustment gap to match various types of implants with different internal opening diameters, and the tilted interface posts will be clamped with the implant under the action of a reset force to ensure that they are always stably connected to the implant during operation.

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described herein are only used to explain the present invention and are not used to limit the present invention.
[0016] See also Figure 1-3 The technical solution of a universal interface of a dental implant surface electrochemical decontamination device provided in this embodiment includes the following: At least two interface posts 2 are arranged at the bottom of the spray end 1 of the electrochemical decontamination device; an adjustment gap 3 is arranged between any two adjacent interface posts 2; the interface post 2 includes a connection section 21 fixedly connected to the spray end 1 of the electrochemical decontamination device and a clamping section 22 fixedly connected to the connection section 21; the universal interface includes at least an unconnected state and a normal implant clamping state; In the unconnected state, any one of the interface columns 2 is perpendicular to the lower end surface of the spray end 1 of the electrochemical decontamination device as a whole; in the normal clamping state of the implant, each of the interface columns 2 is inclined along the adjustment gap 3 toward the center line direction of the spray end 1 of the electrochemical decontamination device, and under the action of the reset force, the outer wall of the clamping section 22 contacts the inner diameter of the large-opening implant.
[0017] Preferably, the interface column 2 of the present invention is arranged at the spray end 1 of the electrochemical decontamination device. The existing electrochemical decontamination device is already very complete, mainly including an electrolyte bottle, a control unit, a pipe rack, a nozzle (the spray end 1 is arranged on the nozzle), etc., so it is not repeated here. The interface column 2 of the present invention is arranged at the bottom of the spray end 1.
[0018] Specifically, the interface column 2 and the spray end 1 are both made of metal with good current conductivity and corrosion resistance.
[0019] Specifically, the outer wall of the clamping section 22 protrudes beyond the outer wall of the connecting section 21, and the outer wall of the clamping section 22 and the bottom surface of the clamping section 22 are processed with rounded corners; the outer wall of the clamping section 22 and the outer wall of the connecting section 21 are connected with chamfered corners.
[0020] Specifically, the spray end 1 is in the shape of a hollow cylinder; Preferably, the most common diameters of oral implants are 3.5mm, 4.0mm, 4.5mm, 5.0mm, etc. Depending on the different tooth positions and alveolar bone conditions, doctors will choose implants of different diameters, and the diameter of the internal opening (internal connection / screw connection) of such implants must be less than 4.5mm and not less than 1.8mm, such as Figure 3 As shown in (c), if the inner opening becomes smaller towards the depth (such as a conical connection), the opening diameter at a depth of 2.5 mm must also be no less than 1.8 mm. Therefore, in order to ensure that the universal connector can be snapped into the internal opening of the implant, the outer diameter length of the spray end 1 is set in the range of 1.8 mm to 4.5 mm.
[0021] In a specific implementation, the thickness of the interface column 2 and the width of the adjustment gap 3 can be selected to have corresponding values according to the inner diameter of the implant commonly used in actual use.
[0022] Specifically, two interface columns 2 are provided, and the two interface columns 2 are symmetrically arranged on the lower end surface of the spray end 1. Similar to the above content, in order to ensure that the universal connector is snapped into the internal opening of the implant and to ensure that a reset force can be generated; the distance between the outer walls of the clamping sections 22 of the two interface columns 2 is 1.8mm to 4.5mm.
[0023] Preferably, in combination with the above content and the attached Figure 3 , attached Figure 3 Figure (c) shows a conical connection implant. The inner opening of this type of implant becomes smaller towards the depth, and includes a conical opening and a cylindrical opening connected to the bottom of the conical opening. In order to ensure that the universal interface can be snap-connected with the conical connection implant, the length of the interface column 2 needs to be set to be greater than 2.5 mm (crossing the conical opening and connecting with the cylindrical opening).
[0024] Specifically, a cylindrical hollow portion is provided inside the spray end 1, and the outer diameter of the cylindrical hollow portion matches the outer diameter of the tube for conveying electrolyte in the electrochemical decontamination device; the width of the adjustment gap 3 is not less than the outer diameter of the cylindrical hollow portion.
[0025] Specifically, the intersection edges of any two surfaces of the interface column 2 adopt arc transition.
[0026] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
