Description
Technical Field
The invention relates to a guide sleeve, in particular to a nose limiting guide cylindrical structure, a tooth implantation limiting tool set and a tooth implantation guiding limiting tool set which are suitable for a dental handpiece and can limit the drilling depth.
Background
With the development of dental technology, more and more patients choose to solve the problem of missing teeth by means of tooth implantation. Dental implants are implants of metal implants (artificial tooth roots) into the alveolar bone of the oral cavity to replace the original tooth roots. After the implant is tightly combined with the bone for a period of time, the artificial crown or bridge is installed to restore the beauty and chewing function.
Dental implant is an invasive dental restoration technique, in which a hole of a suitable size is cut in an alveolar bone by a hand (hand) before a metal implant is implanted into the alveolar bone of an oral cavity. The mobile phone is provided with a cutter with a proper size, and a doctor drives the cutter to drill a hole on the alveolar bone in a way of holding the mobile phone by hand. However, in most cases, there are other teeth on both sides of the drilling position, and the patient has a limited opening width, which limits the cutting space. On the other hand, the practitioner must carefully calibrate his/her vision during drilling to avoid undesirable holes that are too deep and have a tendency to collapse. However, in most cases, the cutting simultaneously generates many chips and blood splash to affect the sight. Unfortunately, prolonged procedure time due to careful handling can seriously affect patient safety and comfort.
At present, advanced people design an additional cutter relay sleeve between the cutter and the mobile phone. The outer and inner sides of the cutter relay sleeve are rotatably combined. The upper part of the cutter relay sleeve is combined with the mobile phone, the lower part of the inner side of the cutter relay sleeve is combined with the cutter, and another handle bites the outer side of the cutter relay sleeve. When an operator starts the cutter and holds the handle by one hand, the outer side of the cutter relay sleeve does not rotate, the downward obstruction of the mobile phone is formed below the non-rotating outer side, and the cutting depth of the cutter can be limited. However, the prior art has several disadvantages in that the components thereof increase the volume or height to a considerable extent, and are not easy to handle in a limited oral space, especially for drilling in the posterior molar region. Then, the joint between the rotating member and the positioning member in the prior art will generate a certain degree of operation wear. Furthermore, the structure of the prior art is complicated and precise, resulting in high manufacturing cost of the product.
Therefore, there is a need in the art for a dental implant drilling solution that solves the above problems.

Please refer to fig. 1A to 1D and fig. 2. Fig. 1A to 1D are exploded, side, top, and bottom views of a nose stop guide barrel 1 according to an embodiment of the present invention. Fig. 2 is a schematic view of the handpiece limit guide cylinder structure combination handheld implement of fig. 1A. The handpiece spacing guide cylindrical structure 1 of the present invention is used for being mounted on a hand-held implement 2 and limiting the drilling depth of the hand-held implement 2. The hand-held implement 2 comprises a handpiece 20 for connection to the tool 3. The machine head limiting guide cylindrical structure 1 comprises a C-shaped plate 10, a machine head adapting structure 12 and a C-shaped pipe structure 14. C-shaped plate 10 has an internal recess 100 and first and second sides 101 and 102 opposite to each other. The head adapter structure 12 is disposed on the first side 101 and has a first lateral opening 120 communicating with the internal recess 100. The head adapter 12 has a head accommodating space therein. The C-shaped tube structure 14 is disposed on the second side 102 and has a second lateral opening 140 communicating with the concave recess 100. Inner diameter length D2 of nose adapter structure 12 is greater than bore diameter length D1 of central bore 105 so that first side 101 of C-shaped plate 10 is abutted by nose 20 when nose limiting guide barrel 1 is assembled to handpiece 2. The outer diameter length D4 of the C-shaped pipe structure 14 is smaller than the outer diameter length D0 of the C-shaped plate 10, so that the C-shaped pipe structure 14 can penetrate into the interdental space to drill a hole.
The hand-held implement 2 may be a handpiece (handtool) commonly used in dental surgery for mounting the tool 3. The tool 3 is a dental tool or a dental drill to which the hand-held implement 2 can be attached. The C-shaped plate 10 is not limited to a plate type; between the head adapter structure 12 and the C-tube structure 14, structures providing the same function can be considered as one of the C-shaped plates 10.
The shape of the head adapter 12 is a cylindrical shape extending outward from the first side 101 of the C-shaped plate 10, and the head accommodating space is provided therein for accommodating and fastening the head 20. The cylindrical shape is a substantially circular shape having no corners and at least one of the two ends has an opening. The inner shape of the handpiece adapter structure 12 corresponds to the structure of the handpiece 20 and is configured to resiliently engage the handpiece 20. The C-shaped tubular structure 14 is in the form of a cylindrical tube extending outwardly from the second side 102 of the C-shaped plate 10. Even further, the C-shaped tube structure 14 may be configured to be non-circular, such as oval, polygonal, concave, etc., to conform to interdental spaces.
The machine head limiting and guiding cylindrical structure 1 is simple in structure and low in manufacturing cost. Moreover, the volume of the handpiece limit guide cylindrical structure 1 installed behind the handheld implement 2 is almost equal to the original volume of the handheld implement 2, so the handpiece limit guide cylindrical structure 1 does not occupy the operation space. Because the nose limiting guide cylindrical structure 1 of the present invention is fixed on the nose 20, rather than between the nose and the tool in the prior art, the length of the tool is not extended, and the nose limiting guide cylindrical structure is not limited by the opening range or the drilling position. Furthermore, the machine head limiting and guiding cylindrical structure 1 does not directly contact with the cutter 3, and the machine head limiting and guiding cylindrical structure 1 does not need to be provided with a rotating element and cannot be worn in the operation process. The machine head limiting guide cylindrical structure 1 is clamped and fixed on the machine head 20 by using a structure, can be disassembled and assembled by simple force application, and is convenient and quick to replace. In addition, the independence of the machine head limiting guide cylindrical structure 1 and the cutter 3 is high, and the cutter 3 does not need to be disassembled firstly when the machine head limiting guide cylindrical structure 1 is replaced; on the contrary, the replacement of the cutter 3 does not require the first disassembly of the nose limiting guide cylindrical structure 1. Finally, since the hand-held implement 2 has water jets directed toward the tool, the side opening design allows water to be jetted up to the drill hole for smooth cooling of the operating temperature and removal of blood debris.
In one embodiment, the C-shaped plate 10, the head adapter 12 and the C-shaped tube 14 are three components that are assembled, joined, clamped or welded to each other to form the head restraint guide cylinder 1.
In another embodiment, the C-shaped plate 10, the head adapter structure 12, and the C-shaped tube structure 14 are integrally formed metal structures and are additively manufactured by three-dimensional metal printing. The integrally formed metal structure can improve the structural stability and the elastic toughness of the machine head limiting guide tubular structure 1, is favorable for being arranged on a handheld machine tool 2, and is not easy to disintegrate in the drilling operation process with high torque force. Compared with material reduction manufacturing, the material increase manufacturing is more suitable for the special and small-sized nose limiting and guiding cylindrical structure. The handpiece accommodating space corresponds to the exterior of the handpiece 20, so that the handpiece 20 can be detachably combined with the handpiece adapting structure 12. One end of the machine head adapting structure 12 is jointed with the C-shaped plate 10, and the other end can be a full opening, a tapered opening or no opening, but can form a machine head accommodating space.
Please refer to fig. 3A to fig. 3D. Fig. 3A and 3B are perspective views of a nose stop guide barrel according to various embodiments of the present invention. The C-shaped pipe structure 14 has a tool accommodating space 145 for the tool 3 to pass through. The other end of the C-shaped pipe structure 14 is a tool through-hole 141, so that the tool 3 can penetrate through the tool concave notch 100, the tool accommodating space 145 and the tool through-hole 141. That is, when the tool 3 is mounted on the hand tool 2 and is operated, the tool 3 does not directly contact the C-shaped pipe structure 14.
As shown in fig. 3A and 3B, the operator can determine the length of the tool 3 exposed from the tool insertion/removal port 141 of the C-shaped pipe structure 14 and thus the drilling depth by replacing the head-limiting guide cylindrical structures 1P, 1Q, 1R, and 1S of the C-shaped pipe structures (e.g., the C-shaped pipe structures 14P, 14Q, 14R, and 14S) having different lengths. Fig. 3C and 3D are schematic views of drilling using the nose stop guide cylinder 1R and the nose stop guide cylinder 1P of fig. 3B. As shown in fig. 3C and 3D, the handpiece limit guide cylinder 1 is fixed to the handpiece 20, and when the hand-held implement 2 with the handpiece limit guide cylinder 1 is operated on a working plane (teethridge), the C-shaped pipe structure 14 abuts against the working plane to limit the movement of the handpiece 20 to the working plane. Correspondingly, the tool 3 driven by the head 20 can no longer drill deeper. Thus, the C-tube structure 14 limits the depth of the borehole.
As mentioned above, the drilling depth can be determined by selecting the nose limit guide cylinder of the C-tube structure with different lengths, for example, when the operator intends to drill a shallower hole in the alveolar bone 4 with the tool 3, the hand-held tool 2 can be attached to the nose limit guide cylinder 1R having the longer C-tube structure 14R. In this case, the tool 3 is less exposed from the C-shaped tubular structure 14R, so that the hole is drilled more shallowly. When the operator wants to drill a deeper hole in the alveolar bone 4 with the same tool 3, the handpiece 2 is replaced with the handpiece limit guide cylindrical structure 1P having the shorter C-shaped pipe structure 14P. At this time, the tool 3 is exposed from the C-shaped pipe structure 14P more, so that the hole is drilled deeper.
According to the invention, after an operator selects the drilling depth, the machine head limiting guide cylindrical structure 1 with relative length is replaced, and the drilling position and angle are determined, so that the deep drilling can be intuitively carried out. When the preset drilling depth is reached, the operator may feel that the hand-held implement 2 is blocked and stopped without continuously and repeatedly visually estimating the drilling depth.
Since the shank 30 of the tool 3 is generally smaller in diameter, the aperture length of the concave recess 100 of the tool can be narrower, so that the first side 101 of the C-shaped plate 10 has a larger area for clamping the head 20. Since the nose 31 of the tool 3 is generally large in diameter and the C-shaped pipe structure 14 is prevented from being worn by contacting the nose 31, the tool accommodating space 145 and the tool passing-through hole 141 need to be large in diameter to prevent debris from accumulating in the tool accommodating space 145 during drilling.
In addition, the top or side of the nose adapter 120 may have a protruding latch 127 to latch the nose 20 and prevent the nose stop guide barrel 1 from slipping off.
Please refer to fig. 1A, fig. 1B, fig. 1C, fig. 4A and fig. 4B. Fig. 4A and 4B are schematic views of the arc angles of the nose limiting guide cylinder according to fig. 1A. As shown in fig. 4A and 4B, the C-shaped plate 10 has a virtual vertical axis Y falling on the central axis of the C-shaped plate 10. The C-tube structure 14 and the nose adapter structure 12 each extend parallel to the virtual vertical axis Y. The C-shaped plate 10 has a central through hole 105, the central through hole 105 communicates with the concave recess 100, and the virtual vertical axis Y passes through the central through hole 105. The cross-section of the core adaptor structure 12 defines a first arc. The two ends of the first arc extend around the virtual vertical axis Y to form an included angle of a first angle A1, wherein the first angle A1 is between 160 and 210 degrees. Conversely, the first opening angle of the first lateral opening 120 around the virtual vertical axis Y is between 150 degrees and 200 degrees. The opening size of the first lateral opening 120 facilitates coupling and clamping of the handpiece 20 and facilitates removal of the handpiece 20 from the handpiece adapter structure 12.
The cross section of the C-shaped tubular structure 14 forms a second arc, two ends of the second arc extend around the virtual vertical axis Y to form an included angle of a second angle a2, the second angle a2 is at least 220 degrees and at most 340 degrees. Conversely, the second opening angle of the second lateral opening 140 around the virtual vertical axis Y is between 20 degrees and 140 degrees. When the handpiece 2 and the handpiece limit guide cylinder 1 are engaged in the manner of fig. 2, the second opening angle of the second lateral opening 140 allows the tool to pass into the C-shaped tubular structure 14, and the water column of the water jet hole of the handpiece can also be flushed to the drilling position.
Please refer to fig. 5. Fig. 5 is a schematic view of a tooth implantation position limiting tool set according to an embodiment of the invention. The invention also provides a dental implant limiting tool set which comprises a handheld machine tool 2 and a plurality of nose limiting guide cylindrical structures 1. The hand-held implement 2 comprises a head 20 for driving a tool, the head 20 having a tool mounting side 201. The nose limiting and guiding cylindrical structures 1 are respectively sleeved outside the nose 20, and each nose limiting and guiding cylindrical structure 1 is substantially the same as the nose limiting and guiding cylindrical structure described in the previous embodiment. The machine head 2 is detachably fixed in the machine head adapting structure 12, and the tool mounting side 201 abuts against the first side 101.
In addition, the C-shaped tube structure 14 of each nose limiting guide cylinder structure 1 has different lengths, such as 15mm, 17mm, 19mm and 21 mm. The C-shaped tube structure 14 with different lengths is used for drilling holes with different depths, for example, the C-shaped tube structure 14 with the length can be used for drilling cutting depths of 9mm, 7mm, 5mm and 3mm respectively.
Please refer to fig. 2 and fig. 6. Fig. 6 is a schematic view of a tooth implantation guiding and limiting tool set according to an embodiment of the present invention. In the present embodiment, the tooth implantation guiding and limiting tool set is applied to be used in cooperation with the hand-held device 2. The tooth implantation guiding and limiting tool set comprises a plurality of machine head limiting and guiding tubular structures 1 and a tooth implantation guiding sleeve 5. The efficacy of the means of the hand-held implement 2 and the handpiece limit guide cylindrical structure 1 is substantially the same as that of the previous embodiment, and the detailed description thereof is omitted. The hand-held tool 2, the cutter 3 and the single handpiece limiting guide cylindrical structure 1 are combined in advance, the tooth implantation guide sleeve 5 is fixedly arranged on the operation part in advance, and the combined hand-held tool 2 and the single handpiece limiting guide cylindrical structure 1 can axially slide in the tooth implantation guide sleeve 5. The implant guide 5 further has a top opening 50, a third lateral opening (not shown), a first axial guide hole 51 and a second axial guide hole 52. The top opening 50 is located at one end of the implant guide sleeve 5. The third lateral opening extends from the top opening 50 to the other end of the implant guide sleeve 5.
The inner wall of the first axial guide hole 51 matches the shape of the nose adapting structure 12 of the nose limiting guide cylindrical structure 1, so that the nose limiting guide cylindrical structure 1 can move axially in the first axial guide hole 51.
The implant guide 5 further comprises a dental model fixing element 55 for fixing the implant guide 5 to the tooth. The bottom of the tooth implantation guiding sleeve 5 is provided with a guiding sleeve cutter through hole 54. The outer diameter of the nose limiting guide cylindrical structure 1 is slightly smaller than the inner diameter of the first axial guide hole 51, so that the nose limiting guide cylindrical structure 1 can slide up and down in the first axial guide hole 51. The cutter 3 can penetrate out of the guide sleeve cutter through hole 54 to cut the alveolar bone.
In practice, the operator holds the machine tool and guides the machine head together with the machine head limiting guide cylinder 1 from the top opening 50 into the first axial guide hole 51 and down into the second axial guide hole 52. And a third lateral opening is provided for the passage of a hand held implement arm 22 of the communication handpiece 20. However, the third lateral opening requires a certain deployment angle in order for the hand-held implement arm 22 to pass through. The expansion angle of the third lateral opening enables the machine head 20 and the machine head limiting guide cylindrical structure 1 to easily tilt and rock towards the outer side of the third lateral opening, and further enables the cutter 3 to deviate from the original drilling axis.
In order to prevent the nose 20 and the nose limiting guide cylindrical structure 1 from inclining to the outside of the third lateral opening, the invention further designs a second axial guide hole 52 with a narrower hole diameter and a larger covering angle. The second axial guide hole 52 is matched with the C-shaped pipe structure 14 of the nose limiting guide cylindrical structure 1, and the aperture length of the second axial guide hole 52 is smaller than that of the first axial guide hole 51. At this time, the inner wall where the first axial lead hole 51 and the second axial lead hole 52 communicate has two turns with unevenness. The first axial guide hole 51 and the second axial guide hole 52 can guide the axial movement of the handpiece limit guide cylindrical structure 1 in two stages. The second axial guide hole 52 accommodates the C-shaped tubular structure 14, and when the C-shaped tubular structure 14 is inserted into the second axial guide hole 52, the second axial guide hole 52 covers the C-shaped tubular structure 14 at a larger angle than the first axial guide hole 51 covers the head adapter structure 12. Therefore, the C-shaped pipe structure 14 is coated by the second axial guide hole 52, the machine head 20 and the cutter 3 are less prone to tilting and shaking, and the drilling axis can be stabilized.
In conclusion, the nose limiting and guiding cylindrical structure is mainly beneficial to the grasping of the cutting depth of an operator during drilling. The machine head limiting guide cylindrical structure is simple and low in manufacturing cost; the volume is small, and no additional operation space is needed; when in operation, the machine head limiting guide cylindrical structure is not in direct contact with the cutter, and the problem of operation abrasion is avoided. And the machine head limiting guide cylindrical structures with different specifications can be conveniently replaced, and the operation time is shortened. The tooth implantation guide sleeve can limit the radial movement or inclination of the nose limiting guide cylindrical structure, so that the handheld machine tool can stably move axially.
