[0001] The invention relates to the technical field of dental medical treatment, in particular to a quick-release clamping device for a dental robot implanter. Background Art

[0002] In recent years, as dental implant machines have become increasingly mature, they have been widely used in various dental clinics as mobile devices used by dentists for oral implants.

[0003] Currently, the implant handpiece elbow and implant handpiece motor of dental handpiece equipment are fixed by threads, and the parts are relatively scattered. Since the handpiece elbow needs to be disinfected after surgery, many parts are disassembled after each surgery. After disinfection, reassembly is relatively cumbersome.

[0004] The implanter is fixed in the tooling sleeve of the dental machine head, and then the axial freedom of the cross section of the dental machine is fixed by a top screw, and then a section is fixed by welding. The disadvantages of this method are:

[0005] ① The welding method cannot ensure that the axis of the press drill insertion hole is parallel to the axis of the holder, which affects the doctor's operating feel.

[0006] ② There is a protective coating on the surface of the dental implant machine. Fixing the machine and the machine head tooling by welding cannot ensure stability, and the instrument arm will produce a certain degree of vibration during operation, which will greatly affect the lifespan and appearance of the rigid and fastened welding structure.

[0007] ③ When the oral robot is operating, different dental implant machines with different welding positions relative to the dental machine head tooling are required depending on whether the patient's surgical position is maxillary or mandibular, which increases the cost of the operation. Summary of the invention

[0008] In view of this, the present invention proposes a quick-release clamping device for a dental robot implanter. The device changes the pitch angle of the center axis of the dental handpiece tooling relative to the holder base by pushing and pulling a lead screw, making it easier for doctors to align the drill bit with the patient's surgical site.

[0026] The following is a complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] A quick-release clamping device for a dental robot implant comprises a holder base and a holder rear end connected to each other; the holder rear end is a cylindrical structure, and an active bevel gear and a lead screw are arranged inside the cylindrical structure, wherein the lead screw is parallel to the central axis of the holder rear end, and the active bevel gear penetrates the side wall of the holder rear end and is connected to its bearing; one end of the lead screw is provided with a conical tooth, and the conical tooth is meshed with the active bevel gear;

[0028] The side wall at the rear end of the gripper is also provided with two opposite long grooves; a slider is constrained in the long groove to move parallel to the central axis of the rear end of the gripper; the slider passes through the two long grooves and is threadedly connected to the lead screw;

[0029] The other side of the rear end of the gripper is hinged with the front end of the gripper; a linkage rod hinged to the front end of the gripper is provided in the middle of the front end of the gripper, one end of the linkage rod is hinged to the front end of the gripper, and the other end is hinged to the slider;

[0030] A slide groove is arranged on the top of the front end of the holder, and the tooth machine head tooling is installed in the slide groove.

[0031] The front end of the holder is also provided with a plurality of locking holes, and the plurality of locking holes are arranged in an array along the extension direction of the slide groove; the tooth machine head tooling is provided with a through hole; and the locking pin passes through the locking hole and the through hole located on the same straight line.

[0032] The mounting end of the dental handpiece tooling is provided with a fixing cap, which is connected to the dental handpiece tooling through screws. The main body of the fixing cap is a hemispherical surface, and an opening is provided at the center thereof.

[0033] Reference Figures 1 to 4 This embodiment designs an assembly method of a guide rail type dental handpiece tooling (the dental handpiece tooling can move along the slide groove) and a holder, which makes it easier for doctors to intuitively feel and adjust the distance from the patient's oral affected area, and the fastening method of the guide rail drilling assembly screws solves the defect that the face gears need a very large pre-tightening force to engage with each other and are easy to loosen.

[0034] The dental machine head tooling and the slide are connected by a locking pin, which can avoid binding and welding between the two. If the doctor wants to replace other types of dental machines, they can install them directly.

[0035] The structural design is more reasonable. The conventional face gear meshing and fastening method has basically no anti-rotation function due to the small flexibility of the material, and the processing cost is too high. The method of fastening the dental machine in this embodiment is that the fixing cap passes through the dental machine wire and is connected to the dental machine head tooling by long screws. The three screws are evenly distributed on the edge of the working tail of the dental machine head, so that the direction of the lower pressure line is colinear with the center of the dental machine tail, thereby achieving the axial plane force balance to the greatest extent. This method will not occupy the space of the doctor's hand-holding position, and is more conducive to the doctor's control of the dental machine during surgery.

[0036] A connection device between the end of a dental implant robot mechanical arm and a dental implant machine, such as Figure 1 Including: the base of the end-of-arm gripping device 1, the rear end of the gripper 2, the active bevel gear 4, the lead screw 9, the linkage rod 6, the fixing cap 10, the tooth head tooling 7, the slide block 5; 3 M2.5 screws, 2 M2.5 screws (L10), a total of 5 parts;

[0037] The robot arm and the base 1 of the holding device at the end of the robot arm are installed in coordination, the base of the holder and the rear end of the holder are installed by a general spring quick release method, the rear end and the front end of the holder are connected by a hinge, the tooth head tooling 7 and the front end of the holder are assembled by fastening with a slide groove and a locking pin, and the fixing cap 10 and the tooth head tooling are assembled with screws.

[0038] The working principle of the present invention is: during the dental implant surgery performed by the dentist on the patient, the dental implant navigation and positioning system needs to be used. The device of the present invention is equivalent to the instrument part of the navigation and positioning system. First, after the navigation and positioning system and the mechanical arm planning are completed and ready, the doctor installs the front and rear ends of the holder on the holder base through the quick-release fixing device, uses the tool to rotate the bevel gear to adjust to the appropriate angle, embeds the slider end of the dental machine head tooling into the slide groove at the front end of the holder, adjusts the appropriate distance, and uses the locking pin to fix the two. Then, the dental machine is inserted from the fixing cap installation end of the holder tooling, and the three top screws are tightened at the other end to return the axial degree of freedom of the dental machine to zero. Then, the fixing cap is inserted from the end of the power cord of the dental machine to one end of the dental machine head tooling, and the fixing cap is installed on the dental machine head tooling using the lengthened screw, and the screw-in depth of the three screws is made as consistent as possible. After the screws are screwed in, the installation of the terminal instrument part is completed. The problem of the inconvenience of adjusting the fixed position of the dental implant machine on the mechanical arm is solved, and the instrument processing cost is also saved. It improves the doctor's operating feel during the operation and provides the doctor with more convenient surgical tools.
