Periodontitis and peri-implant inflammation are some of the most common chronic diseases known to man. They are caused by various bacteria, viruses, their toxins and mineralized deposits (collectively "accretions") adhering to the tooth/implant surfaces above and below the gum line, which cause inflammation, damage to the supporting structure of the tooth/implant and cause possible tooth/implant loss. As the support structure is destroyed, a "periodontal pocket" is formed between the gingiva and the tooth/implant, which needs to be disposed of as it tends to cause reinfection and prevents patients and clinicians from accessing all the growths.
Current treatment protocols include a first step of removing the accessible augmentation by manual and powered tooth cleaning tools.
The present embodiments provide a tooth cleaning implement for cleaning teeth, including but not limited to cleaning of mineralized deposits (collectively "accretions"), inflammation, accretions, etc. from the tooth surface. The tooth cleaning tool includes a hand-held portion that is electrically connectable to a power source to facilitate operation of the tooth cleaning tool. Meanwhile, the tooth cleaning tool also comprises a tip connected with one end of the handheld part far away from the power supply, and the tip can be contacted with the surface of the tooth so as to clean the tooth.
As shown in fig. 1 and 2, the present embodiment provides a tip for a tooth cleaning tool, which comprises a long shaft 100 and a tip 200. Wherein, the long shaft 100 is connected with the hand-held part and extends towards the direction far away from the hand-held part, the end head 200 is arranged at one end of the long shaft 100 far away from the hand-held part, and the end head 200 is used for cleaning teeth. The long shaft 100 can extend the length of the cleaning tool, so that the tip 200 can be conveniently extended into the oral cavity to clean any one tooth, and the tooth cleaning tool can be extended into the oral cavity to be cleaned without being limited by the oral cavity. It will be appreciated that since the tip 200 is used to treat teeth, the tip 200 is of a smaller size and the cross-sectional dimension of the tip 200 is progressively reduced in a direction away from the long axis 100 in order to enable the tip 200 to penetrate into the root of the tooth. The tip 200 is made of plastic, so that the tip has moderate strength when contacting with teeth, and the teeth are prevented from being damaged. Meanwhile, the plastic material has certain toughness, which is beneficial to ensuring the service life of the end head 200. In particular, the plastic material is preferably food grade PEEK plastic.
In general, the joint between the threaded portion 121 and the non-threaded portion 121 is weak, and in the prior art, the joint is located at the end face of the tip, so that when the tip is subjected to the reverse action force of teeth during tooth cleaning, the joint forms a shearing force at the joint, and the joint is weak in strength, so that the joint is broken.
With reference to fig. 1, in order to solve the above problem, the long shaft 100 includes an extending shaft 110 and a connecting shaft 120, the connecting shaft 120 is connected to the extending shaft 110 and extends in a direction away from the connecting shaft 120, the connecting shaft 120 includes a threaded portion 121, the threaded portion 121 is disposed at an end of the connecting shaft 120 away from the extending shaft 110, a connecting hole 210 is opened at an end of the end 200, the threaded portion 121 is engaged with the connecting hole 210 to connect the end 200 and the connecting shaft 120, and a length of the threaded portion 121 is smaller than a depth of the connecting hole 210. The length of the threaded portion 121 is smaller than that of the connecting hole 210, so that the connecting portion where the threaded portion 121 is arranged and the connecting portion where the threaded portion 121 is not arranged are located in the connecting hole 210, the connecting hole 210 can support the connecting portion, structural strength of the connecting shaft 120 is improved, and service life of the long shaft 100 is prolonged. Because different end heads 200 are required to be selected for treating different tooth surface problems, and the working process of the end head 200 often rubs with teeth, the end head 200 is a wearing part and is in threaded connection with the connecting shaft 120, so that the end head 200 can be replaced in time, the tooth cleaning tool can be conveniently applied to various environments, and the application range is expanded.
In the prior art, the length of the threaded part is 3mm, and the length is consistent with the depth of the connecting hole. In order to avoid the fracture near the transition position between the threaded portion 121 and the non-threaded portion 121 of the connecting shaft 120, the depth of the connecting hole 210 is 2.0mm to 3.5mm, and the length of the corresponding threaded portion 121 is 1.5mm to 2.5mm, so as to ensure that the length of the threaded portion 121 is smaller than the depth of the threaded hole 212, which is beneficial to ensure the connecting strength between the long shaft 100 and the end head 200 and avoid the fracture of the long shaft 100. Illustratively, when the depth of the connection hole 210 is 3.5mm, the length of the threaded portion 121 may be 1.5mm, 2.0mm, 2.5mm.
As shown in fig. 1 and 2, the cross-sectional shape of the long shaft 100 is circular, and the whole long shaft 100 may be a tapered structure, and the diameter of the long shaft 100 is gradually reduced from the extension shaft 110 to the connection shaft 120, so that the weight of the long shaft 100 can be reduced, and the diameter of the end of the long shaft 100 close to the tip 200 is too large to easily block the sight of the operator due to the small size of the oral cavity, which is inconvenient for the operator to operate. Meanwhile, since the tip 200 has a smaller size, in order to facilitate the connection between the tip 200 and the long shaft 100, the diameter of the end of the long shaft 100 close to the tip 200 needs to match the size of the tip 200, that is, the size is smaller. In the embodiment, the diameter of the long shaft 100 gradually decreases from the extension shaft 110 to the connection shaft 120, so that the connection between the connection shaft 120 and the end 200 is ensured, the size is gradually changed, and the appearance is attractive.
In other embodiments, the long shaft 100 is partially tapered near the end of the tip 200, and the tapered configuration is also in the direction from the extension shaft 110 to the connection shaft 120, and the diameter of the long shaft 100 gradually decreases. The location of the long axis 100 without the tapered structure ensures the structural strength of the long axis 100. The purpose of the tapered configuration is primarily two, the first being to facilitate accommodation of the tip 200 for attachment of the tip 200, and the other being to avoid having the end near the mouth with an excessively large diameter that obstructs the view of the operator.
Referring to fig. 2, the connection hole 210 includes two sections, a through hole 211 and a threaded hole 212, the through hole 211 extends from an end of the tip 200 close to the long shaft 100 to the inside of the tip 200, the threaded hole 212 is connected to the through hole 211, and the threaded hole 212 is engaged with the corresponding threaded portion 121, so as to facilitate threaded connection, thereby improving convenience in replacing the tip 200. The through hole 211 is used to contact a position where the coupling shaft 120 is not provided with a screw thread.
Specifically, the connecting shaft 120 further includes a neck portion 122, the neck portion 122 is connected to the extending shaft 110, the threaded portion 121 is disposed at one end of the neck portion 122 away from the extending shaft 110, when the connecting shaft 120 is connected to the terminal 200, the neck portion 122 can extend into the connecting hole 210, the neck portion 122 corresponds to the through hole 211, and the neck portion 122 is supported by the side wall of the through hole 211 of the connecting hole 210, so as to increase the lightness of the connecting shaft 120 and prevent the connecting position of the neck portion 122 and the threaded portion 121 from being easily broken due to a shearing force. It will be appreciated that the neck 122 is a cylindrical structure having a smooth outer peripheral surface.
Preferably, the connecting shaft 120 is disposed at an angle of 50 to 120 ° with respect to the extending shaft 110 so as to be suitable for treatment of different positions of teeth.
Preferably, the connecting shaft 120 is chemically heat-treated to further improve the structural strength of the connecting shaft 120 and prevent the connecting shaft from being broken. In other embodiments, the entire long shaft 100 may be chemically heat treated. The chemical heat treatment can heat the whole long shaft 100 or the structure of the connecting shaft 120, thereby improving the structural strength of the long shaft 100 and avoiding easy fracture.
It is noted that the basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration only, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
