Description
Technical Field
The present invention relates to a telescopic tube, and more particularly to a telescopic tube for assisting a dental implant operation.
Background
Referring to fig. 1A and 1B, fig. 1A is a schematic view of a conventional dental handpiece 8, and fig. 1B is a cross-sectional view of a drill 81 of the dental handpiece drilling a hole with a dental implant guide plate 7. The Dental handpiece 8(Dental handpiece) is also called a Dental drill, is a first-level medical device with the lowest risk in Dental clinical treatment, and can be used for generating cavities of teeth to fill and implant the teeth. In addition, the dental handpiece 8 is also matched with the tooth implantation guide plate 7 in the process of drilling so as to lead the drill bit 81 to be aligned with the set position on the tooth socket 72, thereby improving the success rate of the operation and reducing the risk of tooth implantation. However, since the dental handpiece 8 has clinical problems such as vibration, shaking, and easy sliding when drilling the dental socket 72, it is difficult to accurately align the drill 81 of the dental handpiece 8 with a certain position of the dental socket 72. In addition, the implant guide plate 7 is usually made of plastic or polymer material, and has a thickness of about 1 to 3 mm, so that when the drill 81 of the dental handpiece 8 drills downward through the implant guide plate 7, the axial angle of the drill 81 is still easy to deflect and shift. The drill bit 81 may penetrate at an incorrect position, and the angle of penetration may be offset, which may cause a surgical failure if the angle is slightly different, and may puncture the sinus membrane of the upper jaw or the chin nerve of the lower jaw if the angle is too large.
Therefore, it is worth the thinking of those skilled in the art to reduce the slippage of the dental handpiece 8 during drilling and the deviation of the drilling direction.

Detailed Description
Referring to fig. 2A to 2C, fig. 2A is a cross-sectional view of the telescopic tube 10 of the first embodiment, fig. 2B is a perspective view of the telescopic tube 10, and fig. 2C is a schematic view of the telescopic tube 10 assembled on the dental handpiece 8. As shown in fig. 2C, the telescoping tube 10 is adapted for assembly on a dental handpiece 8. Also, when the telescopic tube 10 is assembled to the dental handpiece 8, the bur 81 is surrounded by the telescopic tube 10. As shown in fig. 2A and 2B, the telescopic tube 10 includes a first end portion 11, a second end portion 12, at least one first supporting spring 11S (two first supporting springs 11S are used as an example in the present embodiment), a third end portion 13 and at least one second supporting spring 12S (two second supporting springs 12S are used as an example in the present embodiment). The first end 11, the second end 12 and the third end 13 are hollow tubes with different sizes, the diameter of the first end 11 is the largest, and the diameter of the third end 13 is the smallest. In addition, the top end of the first end portion 11 is detachably connected to the dental handpiece 8 (see fig. 2C), that is, the first end portion 11 of the telescopic tube 10 is inserted or clamped into the dental handpiece 8 in a manner that the first end portion 11 of the telescopic tube 10 is detachably connected to the dental handpiece 8, so that the top end of the first end portion 11 is detachably connected or fixedly locked. In addition, the top end of the second end portion 12 is overlapped by the tail end of the first end portion 11, two first supporting springs 11S are disposed in the first end portion 11, one end of each first supporting spring 11S abuts against the top end of the second end portion 12, and the other end abuts against the first end portion 11. Thus, the top end of the second end portion 12 is pushed by the first supporting spring 11S, so that the top end of the second end portion 12 abuts against the rear end of the first end portion 11. However, when the second end portion 12 or the first end portion 11 is subjected to an external force, the first supporting spring 11S is compressed, so that the length of the first supporting spring 11S is shortened, and the top end of the second end portion 12 and the top end of the first end portion 11 are close to each other (see fig. 3, fig. 3 is a schematic diagram illustrating the telescopic tube 10 when the volume is shortened).
In addition, the top end of the third end 13 is overlapped by the tail end of the second end 12, two second supporting springs 12S are disposed in the second end 12, and one end of the second supporting spring 12S abuts against the top end of the third end 13, and the other end abuts against the second end 12. Thus, the top end of the third end portion 13 is subjected to the pushing tension of the second support spring 12S, so that the top end of the third end portion 13 abuts against the tail end of the second end portion 12. However, when the third end portion 13 or the second end portion 12 is pressed by an external force, the second supporting spring 12S is compressed, so that the length of the second supporting spring 12S is shortened, and the top end of the third end portion 13 moves toward the top end of the second end portion 12 (i.e., the top end of the third end portion 13 and the top end of the second end portion 12 approach each other, please refer to fig. 3 again). In addition, the third end portion 13 includes at least one through hole 13H, and water can enter and contact the bur 81 of the dental handpiece 8 through the through hole 13H to cool the temperature of the bur 81 when the dental implant procedure is performed.
Referring to fig. 4A and 4B, fig. 4A and 4B are schematic views illustrating a dental handpiece 8 drilling a hole with an extendable sleeve 10. As shown, the telescoping tubes 10 can guide the drill bit 81 to align with a set position on the socket 72 when the telescoping tubes 10 have not yet touched the socket 72. Then, when the telescopic tube 10 contacts the socket 72, the first end portion 11, the second end portion 12 and the third end portion 13 are pushed by the socket 72, and the first support spring 11S and the second support spring 12S are correspondingly compressed, so that the length of the telescopic tube 10 in the axial direction (the vertical direction) is shortened, and the drill 81 is exposed from the telescopic tube 10, and thus the drill 81 can drill downward into the socket 72, that is, the socket 72 is drilled. In this way, the drill 81 can drill downward along the axial direction of the telescopic tube 10, and thus the drilling direction of the drill 81 is less likely to be deviated. In addition, because the telescoping tubes 10 also abut the socket 72 surface (see again FIG. 4B), the telescoping tubes 10 also help reduce slippage of the handpiece 8 during drilling. Therefore, the telescopic tube 10 can assist the dental handpiece 8 in accurate tooth implantation, assist the dentist in aiming at the position of the drill hole of the alveolar 72, assist the direction of the drill, and reduce the deflection and deviation caused by shaking and tension during the drilling operation.
Referring to fig. 5, fig. 5 is a perspective view of the telescopic tube 10 having a plurality of scales 13G. In other embodiments, the surface of the third end portion 13 may be further provided with a plurality of scales 13G for measuring depth. In this way, when the drill 81 drills downward, the third end 13 and the second end 12 move relatively due to the extrusion of the socket 72, and the dental practitioner can read the scale 13G on the surface of the third end 13 to know the depth of the drill 81 drilling downward.
Referring to fig. 6A and 6B, fig. 6A is a perspective view of the telescopic tube 20 of the second embodiment, and fig. 6B is a schematic view of the telescopic tube 20 engaging with the tooth implantation guide plate 7. The telescopic tube 20 differs from the telescopic tube 10 in that: the telescopic tube 20 of the embodiment of fig. 6A and 6B can be used to match a dental implant guide plate 7. In detail, the tooth implantation guide plate 7 includes at least one concave hole 70 (in this embodiment, three concave holes 70 are used as an example), and the rear end of the third end 23 of the telescopic tube 20 includes at least one protruding block 23C (in this embodiment, three protruding blocks 23C are used as an example), the position of the protruding block 23C corresponds to the position of the concave hole 70, that is, the three protruding blocks 23C correspond to the three concave holes 70 respectively. Therefore, the telescopic tube 20 can be engaged with the three concave holes 70 of the implant guide plate 7 through the three protruding blocks 23C without being assembled to the dental handpiece 8, so that the telescopic tube 20 and the implant guide plate 7 of the present embodiment are combined and engaged with each other. In this way, the axial direction of the telescopic tube 20 is fixed by the implant guide plate 7, and when the drill 81 of the dental handpiece 8 is drilled down into the socket 72, the drill can be drilled down along the axial direction of the telescopic tube 20, so that the drilling direction of the drill 81 is not deviated and the axial stability is maintained.
Referring to fig. 7A, 7B and 7C, fig. 7A is a schematic view illustrating the telescopic tube 30 of the third embodiment being locked to the implant guide plate 71, fig. 7B is a cross-sectional view illustrating the telescopic tube 30 being locked to the implant guide plate 71, and fig. 7C is a schematic view illustrating the drill 81 along the axial direction of the telescopic tube 30. As shown, the telescoping tubes 30 differ from the telescoping tubes 20 in that: the telescopic tube 30 of this embodiment can be locked to a dental implant guide plate 71 by means of locking. In detail, an internal thread 710 may be provided on the implant guide plate 71, and the surface of the third end portion 33 of the telescopic tube 30 has an external thread 33C, and the external thread 33C corresponds to the internal thread 710, i.e. the external thread 33C of the third end portion 33 can be screwed on the internal thread 710 of the implant guide plate 71. Therefore, the telescopic tube 30 can be locked and combined on the tooth implantation guide plate 71 without assembling the telescopic tube 30 on the dental handpiece 8. In this way, the axial direction of the telescopic tube 30 is also fixed by the implant guide plate 71, and the drill 81 can be driven downward along the axial direction of the telescopic tube 30, so that the drilling direction of the drill 81 is also not easily deviated.
To sum up, the utility model discloses a telescopic tube can prevent the direction skew of dental handpiece when drilling, and can also avoid the slip when drilling, has the advantage that "it is fixed to bore the direction". The above-described embodiments are merely exemplary for convenience of description, and various modifications may be made by those skilled in the art without departing from the scope of the invention as claimed in the claims.
