"Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0032] Reference Figure 2-Figure 4 As shown, one embodiment of the present application provides a machine tap with integrated drilling and tapping functions, which includes a main body 1, a rear end of the main body 1 is provided with an interface portion 2, and a front end of the main body 1 is provided with a head 3. Optionally, the interface portion 2 is a hexagonal or octagonal interface, etc., which is convenient for matching with a tool.

[0033] Among them, the head 3 includes a tapping part 31 and a drilling part 32. The drilling part 32 is arranged at the front end of the tapping part 31. The drilling part 32 includes a plurality of cutting edges 321 for drilling holes. A thread 311 is circumferentially arranged on the tapping part 31 for tapping while the drilling part 32 is drilling holes.

[0034] Conventional machine tapping, see Figure 1The head 3 generally includes a tapping part 31 and a guide part 33. The guide part 33 has no drilling effect and can only play a guiding role. Therefore, a reamer is needed to expand the hole when preparing the socket. The machine tap with integrated drilling and tapping in this embodiment has a drilling part 32 at the front end of the tapping part 31. The drilling part 32 includes a plurality of cutting edges 321 for drilling, so that drilling and tapping can be achieved at the same time, which can reduce the number of socket drilling times, save tool costs, and improve implantation efficiency.

[0035] For example, when planting a φ3.3 implant, the steps for preparing the socket using the machine tap with integrated drilling and tapping functions in this embodiment include: fixing the point (φ1.4 ball drill) → pilot drill (φ2.2 pilot drill) → neck forming drill (φ2.8 neck forming drill) → tapping (machine tap), and the process only requires three drillings.

[0036] Reference Figure 4 As shown, in one embodiment, a groove 322 is provided between two adjacent cutting edges 321. The groove 322 is used to discharge the waste generated by drilling.

[0037] In one embodiment, a chip groove 312 is provided on the tapping part 31 along the axial direction of the main body 1, and the chip groove 312 is connected to the groove 322 one by one. The cooperation between the chip groove 312 and the groove 322 can further improve the waste discharge efficiency and thus improve the drilling efficiency.

[0038] Optionally, the number of cutting edges 321 is three, and the number of grooves 322 is three. An odd number of cutting edges 321 can effectively avoid the occurrence of resonance. Further, in other embodiments, the number of cutting edges 321 and grooves 322 can be 2, 4, 5, etc., which can be adjusted as needed.

[0039] In one embodiment, the cutting edge 321 has double flank surfaces 34 to further improve the cutting effect.

[0040] Reference Figure 2 As shown, in one embodiment, a first mark 4 is provided on the main body 1, and the first mark 4 is used to identify the tapping depth, so as to facilitate clinical observation and improve the accuracy of operation.

[0041] In one embodiment, the first mark 4 is arranged in a ring shape along the circumference of the main body 1, so as to ensure that the first mark 4 can be identified along the circumference, thereby achieving identification without blind spots.

[0042] In one embodiment, the first mark 4 is a groove annularly arranged along the circumference of the main body 1, and there are multiple grooves arranged along the axial direction of the main body 1. The widths of different grooves are different, which are used to distinguish different scales. For example, commonly used thread tapping depths include 8, 10, 12, and 14. Figure 2It includes three first marks 4, the rightmost first mark 4 corresponds to a tapping depth of 8, the two sides of the middle first mark 4 correspond to 10 and 12 respectively, and the leftmost first mark 4 corresponds to a tapping depth of 14, which is convenient for doctors to quickly identify the tapping depth and facilitates clinical operations.

[0043] In one embodiment, the main body 1 is further provided with a second mark 5, which is used to distinguish the specifications of the machine taps, wherein machine taps of different specifications use different second marks 5. Optionally, the second mark 5 is an ink color mark or the like.

[0044] In one embodiment, the second mark 5 is arranged in a ring shape along the circumference of the main body 1 to achieve a mark without blind spots.

[0045] In one embodiment, an anti-dropout member 6 is provided on the main body 1 at the front end of the interface portion 2. After the tool is plugged into the interface portion 2, the anti-dropout member 6 is tightened against the tool to achieve a self-lifting function.

[0046] In one embodiment, a neck 11 is provided on the main body 1 at the front end of the interface 2, and the anti-slip member 6 is an anti-slip ring, which is sleeved on the neck 11 to prevent the anti-slip ring from falling off. Optionally, the anti-slip member is a PEEK ring or the like.
