Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to an ultrasonic implant drill for maxillary compact bone and an ultrasonic implant assembly. Background Art

[0002] With the increasing maturity of dental implant technology, the use of oral implants for oral function reconstruction has become a routine treatment option. Ultrasonic bone scalpel uses high-intensity focused ultrasound technology to convert electrical energy into mechanical energy through a transducer, and completely destroys the bone tissue that needs to be cut through high-frequency ultrasonic vibrations. This ultrasound is specific to bone tissue and will not damage soft tissue, so it can effectively protect anatomical structures such as mucosa, nerves, and blood vessels; in addition, ultrasonic bone scalpels have high cutting efficiency, precise osteotomy, and less bone loss, so they are increasingly used in oral-related surgeries.

[0003] At present, the implant drills used in clinical practice are matched with implant mobile phones, and there is no corresponding dedicated ultrasonic implant drill that matches the ultrasonic bone knife machine. The existing implant drills have the following problems: ① There is no bone cutting specificity, and there is a risk of damaging mucosal tissue and nerves; ② The cutting efficiency is not high enough, which increases the operation time in areas with harder bones; ③ The cooling method is mostly external cooling, and sterile saline is injected into the implant socket through the small hole on the head of the mobile phone to flush out the bone mud and debris in the socket. However, external cooling may not be sufficient after exceeding 6mm below the bone, causing bone damage and affecting the later bone integration. If double cooling flushing is used, it is necessary to connect the internal and external cooling water pipes to the implant mobile phone at the same time and use a special internal cooling drill needle, which is more complicated.

[0004] Bone density is divided into four categories: Class I bone is hard bone, Class II and III are ordinary bone, and Class IV is porous bone. Different densities of bone are suitable for different designs of blades. Maxillary compact bone belongs to Class I to Class II. Therefore, it is urgent to develop an ultrasonic implant drill suitable for maxillary compact bone to improve bone cutting efficiency, protect important soft tissues such as nerves and blood vessels, and reduce postoperative reactions.

[0044] like Figures 1 to 3 As shown, an ultrasonic implant drill for maxillary compact bone is provided in an embodiment of the present invention, comprising a drill head 1, a neck 2 and an ultrasonic bone knife handle connection part 3 connected end to end in sequence; further comprising a liquid passage cavity 4, the liquid passage cavity 4 extending from the ultrasonic bone knife handle connection end of the ultrasonic bone knife handle connection part 3 through the neck 2 to the top of the drill head 1; the outer diameter of the drill head 1 gradually increases from the end away from the neck 2 to the end close to the neck 2, and the cross-section of the drill head 1 is in the shape of a polygonal star; the drill head 1 is provided with a plurality of blade edges 12 in its extension direction, and a chip groove 13 is provided between each adjacent blade edge 12, and a lateral cutting edge 15 is provided at the tissue contact end of the blade edge 12; a liquid outlet 14 connected to the liquid passage cavity 4 is provided on the top of the drill head 1. The ultrasonic implant drill for maxillary compact bone of the present application can use the water flow impact of the liquid outlet to lift the maxillary sinus mucosa, and can fully reduce the temperature of the surgical area to prevent bone damage. The ultrasonic bone knife instrument is connected via the ultrasonic bone knife handle connection part 3. Since the high-intensity focused ultrasound only has a destructive effect on bone tissue of a specific hardness, it will not only not damage blood vessels and nerve tissues, but can also stop bleeding at the surgical wound, further reducing the incision of minimally invasive surgery. Therefore, the maxillary compact bone ultrasonic implant drill has small trauma, high efficiency, and can protect important anatomical structures such as mucosa and nerves.

[0045] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, the drill head 1 refers to: the working part of the maxillary compact bone ultrasonic implant drill. The bottom wall of the maxillary sinus in the posterior teeth area is relatively dense. The maxillary compact bone ultrasonic implant drill of the present application is specifically used to break through the bottom wall of the maxillary sinus in the posterior teeth area of ​​the maxillary Figure 1 The outer diameter of the drill head 1 gradually increases from the end away from the neck 2 to the end close to the neck 2. This can easily break through the maxillary sinus floor in the maxillary posterior teeth area with higher bone density, and at the same time, the maxillary sinus mucosa can be lifted. The special structure of maxillary compact bone makes the structure and requirements of the drill for maxillary compact bone different from those of maxillary cancellous bone, mandibular cancellous bone, and mandibular compact bone in design, and the use of different drills is specialized.

[0046] The bottom of the maxillary compact bone is denser than the surface bone, and the outer diameter of the drill head 1 gradually increases from the drill tip toward the neck, so that when drilling, the penetration force is stronger and the power is greater.

[0047] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, Figure 2 The cross-sectional shape of the drill head 1 is a polygonal star, and more preferably a triangular star, a quadrangular star, a pentagram, a hexagonal star, a heptagonal star, an octagonal star, etc. The pentagram is a five-pointed star shape known in the art, and the others refer to the pentagram, for example, the hexagonal star has one more corner than the pentagram.

[0048] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, Figure 1 The tissue contacting end of the blade edge 12 is provided with a lateral cutting edge 15, which penetrates the dense sloped cortical bone vault on the upper wall of the maxillary sinus, facilitates the stability of the drill during hole expansion, and avoids the displacement of the implant cavity.

[0049] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, Figure 1 The neck 2 is used to connect the drill head 1 and the ultrasonic bone knife handle connecting part 3. The neck 2 is an extension of the drill head 1, which is convenient for deep preparation of holes when the bone height is large.

[0050] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, the ultrasonic bone cutter handle connection part 3 is used to connect the maxillary compact bone ultrasonic implant drill with an existing ultrasonic bone cutter instrument and to transmit the power required for drilling. The ultrasonic bone cutter handle connection part 3 includes an ultrasonic bone cutter handle connection part interface (such as Figure 3 As shown), it can be connected to the ultrasonic bone knife handle 5 of the ultrasonic bone knife instrument (for example, the docking port structure of the ultrasonic bone knife handle 5 of the international general ultrasonic bone knife instrument, such as Figure 5 shown).

[0051] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, Figure 1, the liquid passage cavity 4 is a hollow structure formed by extending from the ultrasonic bone knife handle 5 connection end of the ultrasonic bone knife handle connection part 3 through the neck 2 to the top of the drill head 1, and the liquid passage cavity 4 includes a first cavity provided in the ultrasonic bone knife handle connection part 3, a second cavity provided in the neck 2, and a third cavity provided in the drill head 1, and the first cavity, the second cavity, and the third cavity are connected end to end in sequence. The first cavity, the second cavity, and the third cavity are all hollow structures, and the inner diameters of the first cavity, the second cavity, and the third cavity can be equal or unequal. In a specific embodiment, the inner diameter of the third cavity is slightly larger than the inner diameter of the second cavity, so that the third cavity can better cooperate with the liquid outlet 14 to cool down and cool the surgical area after the water is discharged, thereby improving the cooling effect, and the impact force of the internal cooling water flow can be used to lift the maxillary sinus mucosa.

[0052] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, Figure 1 The chip groove 13 refers to a V-shaped groove formed in the extension direction of the drill head 1. The chip groove 13 is used to discharge bone chips upward during the hole expansion process, reduce friction heat generation during the drilling process, prevent bone burns and bone necrosis, and reduce the failure rate of dental implants. Figure 1 The blade edge 12 refers to the portion of the outer edge of the drill head 1 where the chip groove 13 is not cut.

[0053] In a specific implementation, the width of the edge 12 gradually increases from the end away from the neck to the end close to the neck. The width of the chip removal groove 13 gradually increases from the end away from the neck to the end close to the neck.

[0054] In a specific implementation, the drill head 1 is provided with a plurality of oppositely disposed cutting edges 12 and a plurality of oppositely disposed chip removal grooves 13. In a specific embodiment, the cutting edges 12 at the same cross section of the drill head 1 have the same width; the chip removal grooves 13 at the same cross section of the drill head 1 have the same width.

[0055] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, Figure 1The top of the drill head 1 is provided with a liquid outlet 14 connected to the liquid through cavity 4, which can reduce the temperature of the surgical area, improve the cooling effect, flush the bone chips, and lift the maxillary sinus mucosa. In a specific embodiment, the aperture of the liquid outlet 14 can be, for example, 0.1mm-1mm, 0.1mm-0.3mm, 0.3mm-0.5mm, 0.5mm-0.8mm, 0.8mm-1.0mm, 0.1mm-0.2mm, 0.2mm-0.3mm, 0.3mm-0.4mm, 0.4mm-0.5mm, 0.5mm-0.6mm, 0.6mm-0.7mm, 0.7mm-0.8mm, 0.8mm-0.9mm, or 0.9mm-1.0mm. The reason why the present application does not open a hole in the side wall of the drill head 1 is that the bone density of the maxillary compact bone is high. If a hole is opened in the side wall, insufficient water pressure will result in failure to lift the maxillary sinus mucosa.

[0056] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, Figure 1 The drill head 1 is provided with a scale marking area 11, which can indicate the drilling depth. The scale marking area 11 includes scale markings, which are marking lines and / or marking grooves of different colors.

[0057] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, the length and outer diameter of the drill head 1 are usually not particularly limited, for example, they can be specifically selected according to the intraoperative situation. In a specific embodiment, the length of the drill head 1 can be 8mm to 15mm, 8mm to 10mm, 10mm to 12mm, 12mm to 15mm, etc. The outer diameter of the drill head 1 is 1.8mm to 6mm, 1.8mm to 3mm, 3mm to 4mm, 4mm to 5mm, or 5mm to 6mm. More specifically, the outer diameter of the drill head 1 is 1.8mm, 2.0mm, 2.4mm, 2.8mm, 3.2mm, 3.6mm, 4.0mm, 4.3mm, etc. The drill head 1 within the aforementioned length and outer diameter range is used to prepare implant cavities of different outer diameters and depths.

[0058] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, Figure 1, the neck 2 includes a first neck 21 and a second neck 22 connected, the first neck 21 is connected to the drill head 1, and the second neck 22 is connected to the ultrasonic bone knife handle connection part 3. The first neck 21 and the second neck 22 have a rounded transition at the connection. The structure is smooth, which avoids stress concentration on the one hand and protects the operator and the patient on the other hand. In order to facilitate intraoperative operation, the extension direction of the first neck 21 and the extension direction of the second neck 22 usually need to meet a certain angle, and the angle between the extension direction of the first neck 21 and the extension direction of the second neck 22 can be 80°~150°, 80°~100°, 100°~120°, 120°~140°, or 140°~150°, etc. In general, the first neck 21 and the second neck 22 are distributed as columnar structures extending along their respective axial directions. The extension direction of the extension direction of the first neck 21 is the axial extension direction of the first neck 21. The extension direction of the second neck 22 is the axial extension direction of the second neck 22.

[0059] In the maxillary compact bone ultrasonic implant drill provided in the embodiment of the present application, the lengths of the first neck 21 and the second neck 22 are usually not limited and can be selected according to the actual intraoperative situation. For example, different models can be selected for posterior and anterior cavity preparation. The length of the first neck 21 can be 8mm to 15mm, 8mm to 10mm, 10mm to 12mm, or 12mm to 15mm, etc. The length of the second neck 22 can be 15mm to 20mm, 15mm to 18mm, or 18mm to 20mm. The outer diameter of the neck 2 is substantially equal to the outer diameter of the drill head 1. In a specific embodiment, the outer diameter of the neck 2 is, for example, 1.8mm to 6mm, 1.8mm to 3mm, 3mm to 4mm, 4mm to 5mm, or 5mm to 6mm. More specifically, the outer diameter of the neck 2 is 1.8mm, 2.0mm, 2.4mm, 2.8mm, 3.2mm, 3.6mm, 4.0mm, 4.3mm, etc.
