Description

Technical Field

[0001] The invention relates to the field of oral dental implantation, and more particularly to an implantation wrench converter and an implantation system. Background Art

[0002] The following background art is used to help readers understand the present invention and is not to be regarded as prior art.

[0003] During dental implant surgery, implants are usually screwed into the prepared cavity using an implant wrench. The implant wrench is equivalent to a screwdriver, and the implant wrench interface cooperates with the implant interface to provide torque. However, there are many brands of implants on the market, and different brands of implants, or even different models of implants of the same brand, have different interface shapes or sizes, which requires the use of different implant wrenches when implanting different implants.

[0004] Previously, dental implant surgery did not require a navigation implant guide, and the implant was screwed directly into the prepared cavity using an implant wrench. However, the precision and accuracy of the implant alignment with the cavity was not high. The current development of digital navigation implant technology is conducive to improving implant accuracy. For implant surgery assisted by digital navigation implant guides, different implant wrenches are required for different implants to achieve implant placement under navigation, which is costly and cumbersome. Summary of the invention

[0005] The purpose of the present invention is to provide an implant insertion wrench converter and an implantation system, which, in conjunction with implant machine insertion wrenches of different brands, can meet the requirements for implantation of implants of different brands or different interface forms of the same brand under the same navigation guide plate guide hole size.

[0006] The technical solution adopted by the present invention to solve its technical problems is: an implant wrench converter, including a conversion drill bit interface, and a swivel connected to the conversion drill bit interface and having an outer diameter matching the aperture of the guide hole of the navigation guide plate, the swivel is provided with a connecting mechanism that can be fixed to the implant wrench. The implant wrench is fixed to the swivel, so that the implant wrench rotates with the rotation of the swivel, i.e., the converter. Preferably, the swivel is a sleeve, and the connecting mechanism includes a protrusion provided in the sleeve. The implant wrench has a wrench drill bit interface, and the wrench drill bit interface on the implant wrench has the same structure and size as the conversion drill bit interface on the converter, is a standard part, and can be adapted to the connector of an implant mobile phone or a manual instrument. The protrusion cooperates with the wrench drill bit interface to achieve the purpose of clamping the implant wrench so that it is relatively fixed to the converter.

[0007] Preferably, the sleeve is provided with a viewing hole, the viewing hole and the sleeve axial hole radially penetrate each other, and the protrusion is located in the visible area of ​​the viewing hole. Through the viewing hole, the insertion angle of the implant wrench can be conveniently adjusted, so that the implant wrench can be quickly and accurately inserted into the converter.

[0008] Preferably, a scale is set on the outer wall of the conversion drill interface for reference of implantation depth.

[0009] Preferably, the conversion drill bit interface is at the top, the sleeve is at the bottom, and the conversion drill bit interface is aligned with the axial center line of the sleeve.

[0010] An implant implantation system comprises a converter, a navigation guide plate and an implant wrench. The converter comprises a conversion drill interface and a swivel. The navigation guide plate is provided with a guide hole. The guide hole and the swivel are clearance-matched. The implant wrench is fixed to the swivel through a connecting mechanism.

[0011] Preferably, the swivel is a sleeve, the connecting mechanism includes a protrusion arranged in the sleeve, the implant wrench has a wrench drill interface, the wrench drill interface has a head section and a tail section, the head section has a notch, the notch is formed along the chordal cut-off part, and the protrusion is adapted to the notch; the tail section is a cylinder, which is matched with the sleeve gap. The protrusion of the converter is matched with the notch of the implant wrench, so that the implant wrench is fixed on the converter, ensuring that the implant wrench rotates when the converter rotates, and the implant wrench and the converter can be fixed by directly inserting the implant wrench into the sleeve so that the protrusion and the notch are matched, which is convenient and fast. It should be noted that the length of the sleeve and the tail section should be sufficient to ensure that the notch of the head section can be fixed with the protrusion in the sleeve.

[0012] A method for using an implant implantation system: insert an implant wrench into a converter so that the notch matches the protrusion, ensure that the implant wrench is stuck in the converter and does not rotate, then match the implant wrench connector with the implant interface, use an implant mobile phone or a manual instrument to apply torque to the converter, and under the guidance of a navigation guide, screw the implant into the implant cavity to complete the navigation implantation process of the implant.

[0013] The beneficial effects of the present invention are as follows: 1. The implant wrench interfaces of different implants are different, but the guide apertures of the navigation guide plates are the same, and a converter can be used to realize the conversion of implant wrenches of different brands and specifications.

[0014] 2. The connection mechanism is configured as follows: the swivel is a sleeve, a protrusion is provided in the sleeve, and the implant wrench is directly inserted into the sleeve so that the protrusion matches the notch to achieve fixation, which is convenient and quick.

[0015] 3. By opening a viewing hole in the converter, the insertion angle of the implant wrench can be easily adjusted, so that the implant wrench can be quickly and accurately inserted into the protrusion of the converter. BRIEF DESCRIPTION OF THE DRAWINGS
