Description

Technical Field

[0001] The utility model relates to the technical field of periodontal membrane separation, in particular to a periodontal membrane separation device with measurement function. Background Art

[0002] During the routine tooth extraction process, the tooth root may be fractured. At this time, due to factors such as bleeding, the human eye cannot see the tooth root clearly, and the remaining tooth root and the alveolar bone cannot be identified. It can be known that the broken tooth root is in the alveolar socket. When using a probe to explore, in the case of a broken tooth root, the depth reached by the probe will be shallower than that of a non-broken tooth root. The probe cannot perform depth measurement, that is, it cannot determine the depth of the alveolar socket, and the probe cannot separate the broken tooth root and the alveolar bone. Other tools need to be replaced, and the operation is more troublesome. Utility Model Content

[0003] The utility model aims to provide a periodontal ligament separation device with measurement function, which can measure the depth of alveolar socket and simplify the operation of separating broken tooth root and alveolar bone.

[0004] A periodontal membrane separation device with measurement function comprises a handle, one end of the handle is connected to a separation knife, the separation knife comprises a knife rod and a knife edge, both the knife rod and the knife edge are provided with scales, and the cross section of the knife edge is triangular.

[0005] In the above scheme, scales are provided on the knife rod and the blade, so that when the separation knife penetrates into the alveolar socket, the depth of the separation knife into the alveolar socket can be measured. Before extracting the tooth, the dentist can take X-rays or dental films of the teeth to evaluate the length of the tooth root, the thickness of the alveolar bone and the depth of the alveolar socket. Therefore, when the measured depth of the separation knife into the alveolar socket is less than the depth of the alveolar socket, it can be determined that the tooth extraction has a root fracture problem. At this time, the blade is inserted into the periodontal membrane from the side of the root. The periodontal membrane is located between the alveolar bone and the root. The blade with a triangular cross-section can more easily pass through the periodontal membrane, loosening the root and reducing the patient's discomfort. The setting of the scale allows the doctor to better control the position and depth of the separation knife, so that the broken root can be separated more safely.

[0006] Furthermore, the cross section of the knife rod is rectangular.

[0007] In the above scheme, the cross-section of the knife rod is rectangular, which can ensure the stability of the separation knife when separating the tooth root and the alveolar bone, so that the tooth root is easier to loosen.

[0008] Furthermore, one end of the blade is a tip, the other end of the blade is connected to the blade rod, and the thickness of the tip is smaller than that of the other end of the blade.

[0009] In the above scheme, the thickness of the blade gradually increases from the tip to the other end. The smaller thickness at the tip makes it easier to wedge between the broken tooth root and the alveolar bone. The gradually increasing thickness is conducive to gradually loosening the tooth root, reducing excessive force on the alveolar bone and surrounding structures, thereby reducing the patient's discomfort.

[0010] Furthermore, the knife rod is in the shape of a flat rectangular parallelepiped, and the knife edge is in the shape of a flat quadrangular pyramid.

[0011] In the above scheme, the flat rectangular knife rod enhances the stability of the separation knife during operation, and for the dentist, it can better control the position and direction of the knife, so as to operate accurately. The flat quadrangular pyramid shape of the knife edge helps to more effectively penetrate the periodontal membrane and gradually separate the tooth root. The quadrangular pyramid design can provide good cutting force and penetration force, making the separation process smoother and more precise.

[0012] Furthermore, the knife rod is in the shape of a flat elliptical cylinder, and the knife edge is in the shape of a flat elliptical cone.

[0013] In the above scheme, the knife rod is in the shape of a flat elliptical cylinder, and the blade is in the shape of a flat elliptical cone, which can enhance the stability and accuracy of the separation device during operation on the one hand, and ensure the smoothness of the surface of the separation knife on the other hand, thereby avoiding unnecessary damage to the periodontal membrane caused by the separation knife during operation, reducing the patient's discomfort and operation risks, allowing the dentist to focus more on treating the tooth root, thereby improving the efficiency and success rate of the separation process.

[0014] Furthermore, the knife rod and the knife edge are integrally formed.

[0015] In the above scheme, the knife rod and the blade are integrally formed so that the separation knife has higher overall strength and stability, which can ensure that the separation knife is not easily deformed or broken during operation, and help improve the efficiency and success rate of the operation.

[0016] Furthermore, a notch is formed at the connection portion between the handle and the separation knife, and the cross section of the notch is trapezoidal.

[0017] In the above scheme, in order to ensure the stability of the separation device, the handle and the separation knife are generally connected in one piece, and a notch is opened at the connection between the handle and the separation knife to ensure that the width of the connection is narrow. In this way, when the separation knife loosens the tooth root, the connection part will not have excessive contact with the alveolar socket, thereby reducing the patient's discomfort. The trapezoidal cross-section of the notch can ensure that the handle and the separation knife are not easy to break.

[0018] Furthermore, the handle is provided with a sheath, and the sheath is provided with anti-slip patterns.

[0019] In the above solution, the sheath can effectively improve the grip and stability of the handle, making it easier for the dentist to control the position and force of the separation device during operation. Especially in wet or precise operation, the anti-slip pattern can effectively reduce the possibility of hand slippage, improve the accuracy and safety of operation, and the sheath can reduce the direct friction of the handle surface on the hand, reducing hand fatigue during long-term operation. This is particularly important for complex or long-term operations, which can improve the dentist's operating efficiency and comfort.

[0020] The utility model provides a periodontal membrane separation device with measurement, which has the beneficial effect of being able to measure the depth of the alveolar socket and simplifying the operation of separating the broken tooth root and alveolar bone. The knife bar and the knife edge are both provided with scales, so that when the separation knife penetrates into the alveolar socket, the depth of the separation knife penetrating into the alveolar socket can be measured. Before extracting a tooth, a dentist can evaluate the length of the tooth root, the thickness of the alveolar bone and the depth of the alveolar socket by taking an X-ray or dental film of the tooth. Therefore, when it is measured that the depth of the separation knife penetrating into the alveolar socket is less than the depth of the alveolar socket, it can be judged that the tooth root is broken during the tooth extraction. At this time, the knife edge is inserted into the periodontal membrane from the side of the tooth root. The periodontal membrane is located between the alveolar bone and the tooth root. The knife edge with a triangular cross section can more easily pass through the periodontal membrane, loosen the tooth root, and reduce the patient's discomfort. The setting of the scale allows the doctor to better control the position and depth of the separation knife, so that the broken tooth root can be separated more safely.

[0026] The following will further describe in detail a periodontal ligament separation device with measurement function according to the present invention in conjunction with specific embodiments and drawings. Example 1

[0027] like Figure 1 and Figure 4 As shown, in a preferred embodiment, a periodontal membrane 7 separation device with measurement function of the utility model comprises a handle 1, one end of the handle 1 is connected to a separation knife 2, the separation knife 2 comprises a knife rod 22 and a blade 21, both the knife rod 22 and the blade 21 are provided with scales, and the cross section of the blade 21 is triangular. There are scales on the knife rod 22 and the knife edge 21, and the scales here are in millimeters, so that when the separating knife 2 penetrates into the alveolar socket 8, the depth of the separating knife 2 penetrating into the alveolar socket 8 can be measured. Before extracting the tooth, the dentist can evaluate the length of the root 9, the thickness of the alveolar bone and the depth of the alveolar socket 8 by taking X-rays or dental films of the teeth. The figure is a simple schematic diagram of the height relationship between the alveolar socket 8 and the broken root 9. The height from the top of the alveolar socket 8 to the top of the broken root is H1, and the overall height of the alveolar socket 8 is H2. When there is no broken root 9, after the separating knife 2 penetrates into the alveolar socket 8, the scale on the separating knife 2 at the top of the alveolar socket 8 is displayed as H2. When there is a broken root 9, after the separating knife 2 penetrates into the alveolar socket 8, the scale on the separating knife 2 at the top of the alveolar socket 8 is displayed as H1, and H1 is less than H2.

[0028] When it is determined that the root 9 is broken during tooth extraction because the depth of the separation knife 2 inserted into the alveolar socket 8 is less than the depth of the alveolar socket 8, the blade 21 is inserted into the periodontal membrane 7 from the side of the root 9. The periodontal membrane 7 is located between the alveolar bone and the root 9. The blade 21 with a triangular cross-section can more easily penetrate the periodontal membrane 7, thereby loosening the root 9. The surgical operation is simplified without the need to replace additional tools, and the patient's discomfort is reduced. The scale setting allows the doctor to better control the position and depth of the separation knife 2, thereby being able to separate the broken root 9 more safely.

[0029] like Figure 1 and Figure 4 As shown, in some embodiments, the cross section of the knife bar 22 is rectangular. The rectangular cross section of the knife bar 22 can ensure the stability of the separation knife 2 when separating the tooth root 9 and the alveolar bone, so that the tooth root 9 is easier to loosen.

[0030] like Figure 1 and Figure 4 As shown, in some embodiments, one end of the blade 21 is a tip, and the other end of the blade 21 is connected to the blade rod 22, and the thickness of the tip is smaller than the other end of the blade 21. The thickness of the blade 21 gradually increases from the tip to the other end, and the tip is thinner to facilitate wedging between the broken tooth root 9 and the alveolar bone. The gradually increasing thickness is conducive to gradually loosening the tooth root 9, reducing excessive force on the alveolar bone and surrounding structures, thereby reducing the patient's discomfort.

[0031] like Figure 1 and Figure 4As shown, in some embodiments, the knife bar 22 is integrally formed with the knife edge 21. The knife bar 22 and the knife edge 21 are integrally formed so that the separation knife 2 has higher overall strength and stability, which can ensure that the separation knife 2 is not easily deformed or broken during operation, and help improve the efficiency and success rate of the operation.

[0032] like Figure 1 and Figure 4 As shown, in some embodiments, the connection portion 6 between the handle 1 and the separation knife 2 is formed with a notch 3, and the cross section of the notch 3 is trapezoidal. In order to ensure the stability of the separation device, the handle 1 and the separation knife 2 are generally connected in an integral molding, and a notch 3 is opened in the connection portion 6 between the handle 1 and the separation knife 2 to ensure that the width of the connection portion 6 is narrow, so that when the separation knife 2 loosens the tooth root 9, the connection portion 6 will not have too much contact with the alveolar socket 8, thereby reducing the patient's discomfort. The trapezoidal cross section of the notch 3 can ensure that the handle 1 and the separation knife 2 are not easy to break.

[0033] like Figure 1 and Figure 4 As shown, in some embodiments, a sheath 4 is provided on the handle 1, and an anti-slip pattern 5 is provided on the sheath 4. The sheath 4 can effectively improve the grip and stability of the handle 1, making it easier for the dentist to control the position and force of the separation device during operation. Especially in wet conditions or when precise operation is required, the anti-slip pattern 5 can effectively reduce the possibility of hand slippage, improve the accuracy and safety of the operation, and the sheath 4 can reduce the direct friction of the handle 1 surface on the hand, reducing the hand fatigue during long-term operation. This is particularly important for complex or long-term operations, and can improve the dentist's operating efficiency and comfort.

[0034] The utility model discloses a periodontal membrane 7 separation device with measurement working principle and process. The separation knife 2 is inserted into the alveolar socket 8. When the scale at the top of the alveolar socket 8 on the separation knife 2 is displayed as the depth of the alveolar socket 8, it indicates that there is no problem of broken tooth root 9. When the scale at the top of the alveolar socket 8 on the separation knife 2 is smaller than the depth of the alveolar socket 8, it indicates that there is a problem of broken tooth root 9. The blade 21 is inserted into the periodontal membrane 7 from the side of the tooth root 9 to loosen the tooth root 9 to achieve separation of the tooth root 9 from the alveolar bone. Example 2

[0035] like Figure 2 and Figure 4As shown, the structure and principle of this embodiment are basically the same as those of the embodiment 1, except that the knife bar 22 is a flat rectangular parallelepiped, and the blade 21 is a flat quadrangular pyramid. The flat rectangular knife bar 22 enhances the stability of the separation knife 2 during operation, and for dentists, the position and direction of the knife can be better controlled, so as to operate accurately. The flat quadrangular pyramid of the blade 21 helps to more effectively penetrate the periodontal membrane 7 and gradually separate the tooth root 9. The quadrangular pyramid design can provide good cutting force and penetration force, making the separation process smoother and more accurate. Example 3

[0036] like Figure 3 and Figure 4 As shown, the structure and principle of this embodiment are basically the same as those of Embodiment 1, except that the knife bar 22 is in a flat elliptical cylinder shape, and the knife edge 21 is in a flat elliptical cone shape. The knife bar 22 is in a flat elliptical cylinder shape, and the knife edge 21 is in a flat elliptical cone shape. On the one hand, the stability and accuracy of the separation device during operation can be enhanced, and on the other hand, the surface of the separation knife 2 is smooth, which can prevent the separation knife 2 from causing unnecessary damage to the periodontal membrane 7 during operation, reduce the patient's discomfort and operation risks, and the dentist can focus more on treating the tooth root 9, thereby improving the efficiency and success rate of the separation process.
