Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a clinical tightening device suitable for dental procedures. Background Technology

[0002] The dental implant procedure involves inserting a biocompatible implant, such as one made of titanium, into the alveolar bone. After a three-month healing period, the implant integrates with the bone, and then the abutment and crown are attached. The abutment and implant are connected by a central screw. Tightening the central screw requires a screwdriver, the tip of which corresponds to the groove on the screw's surface inside the abutment. The clockwise rotation of the screwdriver ensures a tight connection between the implant and abutment. Precise placement and tightening of the central screw are crucial for the long-term stability of the abutment and crown. Even a small misalignment between the abutment and implant can prevent further tightening, even if the central screw is not yet properly in place. In such cases, if the patient removes the crown, complications such as abutment or crown loosening and implant failure can easily occur. However, in clinical practice, dentists often rely on touch to tighten the central screw, making it difficult for implant surgeons, especially younger ones, to accurately determine its placement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tightening device that can count and thus determine whether the tightening is complete.

[0004] To achieve the above objectives, this utility model provides a clinical tightening device suitable for dental procedures, comprising: ontology; The working part is disposed at the bottom end of the body, and the working part includes a screwdriver tip for contacting and rotating a screw; A counting unit is disposed in the middle of the main body, and the counting unit is used to record and display the current number of rotations of the working part; An operating unit is located at the top of the main body. The operating unit is used to control the rotation of the main body and the working part, and to display data in conjunction with the counting unit.

[0005] Preferably, the working part includes a connecting rod and a tip, and the tip, the connecting rod and the body are connected in sequence.

[0006] Preferably, the tip is made of a magnetic material.

[0007] Preferably, the counting unit includes a counter and a connector, the counter and the connector are connected, and the connector is a gear structure.

[0008] Preferably, the operating part includes a handle, which is fixedly connected to the body. When the handle is rotated, the operating part and the body rotate synchronously, and the counter records and displays the number of rotations.

[0009] Preferably, the operating unit further includes a handle for resetting the counter.

[0010] Compared with the prior art, the technical solution proposed in this application has the following beneficial effects: This utility model adopts a mechanical counting device, which can accurately know the number of rotations of the screwdriver and the central screw. By comparing it with the number of rotations after the conventional central screw is accurately in place, it can help clinicians accurately judge whether the central screw is accurately in place and tightly connect the oral implant and the restorative abutment. Attached Figure Description

[0011] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings: Figure 1 This is an overall structural diagram of the present invention; In the diagram: 1. Tip, 2. Connecting rod, 3. Body, 4. Connector, 5. Handle, 6. Lifting handle. Detailed Implementation

[0012] The technical solutions in the embodiments of this utility model will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0013] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0015] See Figure 1 This utility model provides a clinical tightening device suitable for dental clinics, comprising: The system comprises: a main body; a working part located at the bottom of the main body, the working part including a screwdriver tip for contacting and rotating a screw; a counting unit located in the middle of the main body for recording and displaying the number of rotations of the working part; and an operating part located at the top of the main body for controlling the rotation of the main body and the working part, and displaying data in conjunction with the counting unit.

[0016] The working part includes a connecting rod and a tip, which are sequentially connected to the body. The tip is made of a magnetic material. The counting unit includes a counter and a connector, which are connected to the counter and have a gear structure. The operating part includes a handle, which is fixedly connected to the body. When the handle is rotated, the working part and the body rotate synchronously, and the counter records and displays the number of rotations. The operating part also includes a handle for resetting the counter.

[0017] This embodiment uses a mechanical counting device to accurately determine the number of rotations of the screwdriver and the central screw. By comparing this number with the number of rotations after the central screw is precisely in place, clinicians can accurately determine whether the central screw is in place and ensure a tight connection between the dental implant and the restorative abutment.

[0018] It should be noted that the rotary counter is only the optimal choice in this embodiment; other counting tools such as a graduated ring or a pitch scale can also be used. Alternatively, an electronic sensor counter can be used, with a photoelectric or magnetic encoder mounted on the screwdriver shaft, capable of accurately recording the direction and angle of each rotation. Combined with a small screen / LED indicator, the number of rotations can be displayed in real time, and it can even be synchronized to a mobile phone or computer via Bluetooth.

[0019] If high precision is not required, visual or color cues can also be used: Color gradient: A spiral gradient color band is made on the screwdriver shaft or extension. As it rotates, the color changes in a fixed window, allowing the user to quickly perceive the number of rotations.

[0020] Marker point movement: Draw a high-contrast line on the rotating part, and it returns to its original position after each rotation, making it easy to count the rotations with the naked eye.

[0021] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, nor to combinations thereof. Those skilled in the art can make various changes, modifications, or combinations within the scope of the claims, which do not affect the substantive content of this utility model. Unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
