Description

Technical Field

[0001] The present invention relates to the field of oral cavity detection, and more particularly to an oral cavity intraocular detection and measurement device. Background Art

[0002] In the field of oral medicine, chronic periodontal disease is an inflammatory lesion of the tooth supporting tissue. In the field of measurement technology, the force applied by the measuring tool to the object being measured is called "measurement force". In situations where the measuring tool must contact the object being measured for measurement, the measurement force must exist to ensure the accuracy of the measurement result. However, this measurement force cannot be too large or too small. At the same time, the measurement force requirements for different types of objects being measured are also different. For example, if the measurement force is too large for a softer object, the object being measured will be partially deformed, thereby affecting the accuracy of the measurement result and the measurement result will be untrue. The insertion force of the periodontal probe is the measurement force, and the control research of the periodontal probe measurement force is to avoid stabbing the patient's tissue. Of course, the accuracy of the measurement must also be considered, because the periodontal probe needs to be inserted to the bottom and contact the bottom of the gingival sulcus; similar to the patent number: CN201 810052281.3 is a multifunctional integrated tool for oral measurement and inspection, comprising an outer sleeve, an oral saliva extraction device, a detection lighting device, a tooth cavity depth detection device, a medicine storage bag, a concave-convex zipper, an inner connecting rod, a tool storage device, an oral cleaning device, a protective cover, an elastic fixing rope and a fixed side piece, wherein the oral saliva extraction device is transversely embedded in the middle and lower part of the outer sleeve; the lower part of the front surface of the detection sleeve of the invention is also engraved with scale lines, which is convenient for detecting the depth of the patient's tooth cavity in conjunction with the detection rod and the slider; the oral speculum, oral tweezers and oral probe are respectively connected to the inner side of the storage frame through the connecting shaft, which is convenient for storing and organizing oral inspection instruments without affecting the normal use of oral inspection instruments; the coordinated arrangement of the liquid extraction pump, the liquid extraction tube and the liquid outlet tube is convenient for extracting the saliva in the patient's mouth into the saliva collection bag, thereby increasing the use function;

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature. Specific implementation method one:

[0084] like Figure 1 — Fig.44As shown, an intraoral camera detection and measurement device includes a probe 1, a handle 2, a knob 3, a body 4, a cable 5, a relay box 6 and a style setter 12. The handle 2 is connected to the body 4 through the knob 3, the body 4 and the relay box 6 are connected through the cable 5, and the probe 1 and the style setter 12 are switched and connected to the handle 2 for use.

[0085] The working principle and beneficial effects of this embodiment are as follows: the handle 2 of the present invention can be conveniently connected or disassembled with the machine body 4 through the knob 3. First, the connecting cylinder 2a7 of the handle 2 is inserted into the knob 3, and then the knob 3 is rotated clockwise to make the arc internal thread 3b2 in the knob clamp 3b and the arc external thread 2a6 on the handle screwed together and tightened to connect and fix the handle 2 to the machine body 4. At this time, the cylindrical end face 2a8 of the handle body 2a contacts the stop step 4a5 of the box body 4a, and the handle 2 can be fixed at any angle relative to the machine body 4 to facilitate measurement. The separable structure of the two facilitates sterilization and disinfection of each separately.

[0086] By switching between the measuring needle 1 and the style former 12, which are used for detecting the inside of the oral teeth and shaping the teeth respectively, the style former 12 is used for visually observing and detecting the tooth structure, while facilitating the processing of the mold for different oral problems. Through tight fitting shaping, it is convenient to quickly process braces that fit different teeth or the entire combination of teeth, and directly obtain the corresponding protection tools while being used for detection. Specific implementation method 2:

[0088] like Figure 1 — Fig.44 As shown, an intraoral camera detection and measurement device, the handle 2 includes a handle body 2a, a push rod 2b, a lever 2c, a needle shaft 2d, a lever shaft 2e, a handle cover 2f and a screw 2g, and the handle cover 2f is connected and fixed to the handle body 2a by a plurality of screws 2g;

[0089] The handle body 2a is in the shape of a rectangular box with a cavity. An opening 2a3 is provided at the arc-shaped end of the handle body 2a. An extended support arm 2a2 is provided at the lower end of the opening 2a3. A needle sleeve hole 2a1 in the shape of a stepped hole is provided at the end of the support arm 2a2. A cavity 2a12 is provided at the lower side of the front end of the handle body 2a. An axial boot 2a15, a partition 2a14 and a hollow column 2a11 are provided in the cavity 2a12. A push rod hole 2a13 is provided on the partition 2a14. The push rod hole 2a13 is provided through the closed end of the handle body 2a. A base cylinder 2a5, an arc external thread 2a6 and a connecting cylinder 2a7 are provided on the outer side of the closed end of the handle body 2a. The arc external thread 2a6 is evenly distributed along the circumference on the outer surface of the base cylinder 2a5. The push rod hole 2a13 is provided through the connecting cylinder 2a7.

[0090] The push rod 2b is inserted into the opening 2a3 and the push rod hole 2a13, the handle cover 2f is buckled and connected with the handle body 2a, the shaft boot 2a15 in the handle body 2a is aligned with the shaft boot 2f2 on the handle cover 2f, the lever 2c is set in the gap between the shaft boot 2a15 and the shaft boot 2f2, the lever shaft 2e is set in the circular hole of the shaft boot 2a15 and the shaft boot 2f2, the hand shaft boot 2f2 is provided with a concentric screw hole 2f1, and the screw 2g is inserted into the screw hole on the lever shaft 2e through a threaded fitting connection to fix the handle cover 2f;

[0091] The end of the lever 2c is provided with a lever head 2c4, which is semicircular both above and below. The lever head 2c4 is provided with a slot 2c3 and a through hole 2c2 that penetrate through the upper and lower parts. The outer end of the slot 2c3 is provided with a symmetrical inclined surface 2c9. Both sides of the inner wall of the slot 2c3 are provided with a needle shaft hole 2c8, and a needle shaft 2d is inserted in the needle shaft hole 2c8. The needle shaft 2d is provided with a longitudinal through hole 2d1, and a measuring needle 1 is inserted in the longitudinal through hole 2d1.

[0092] The working principle and beneficial effects of this embodiment are as follows: the push rod 2b is inserted from the left opening 2a3 of the handle body 2a, and enters the push rod hole 2a13 and the push rod hole 2a9. The stop ring 2b1 of the push rod 2b can limit the movement of the push rod until it hits the partition 2a14. The two ends of the push rod 2b are spherical, so that when being pushed by the lever 2c or pushing the piston shaft 4d, point contact and smooth transition can be maintained. When the handle cover 2f is buckled on the handle body 2a, the outer contour of the handle cover 2f is consistent with the handle body 2a, and the edge of the handle cover 2f is in close contact with the cover surface 2a4 of the handle body 2a, and the three holes 2f1 of this cover are respectively aligned with the holes on the handle body 2a. When the lever 2c is in the lower position, the shaft shoe 2a15 and the shaft shoe 2f2 in the handle body 2a are aligned but not in contact with each other. The width of the gap between the two is just equal to the thickness of the lever 2c. The lever shaft 2e is just in the shaft shoe 2a15 and the shaft shoe 2f2. Therefore, the lever shaft 2e must be placed first, and then the lever 2c is placed, that is, the lever shaft 2e is inserted into the lever shaft hole 2c6, and then the handle cover 2f is covered and the three screws 2g are tightened. The screws 2g can clamp the lever shaft 2e, but the lever 2c can rotate freely around this axis. When the lever 2c is in the lower position, the long rod 2c1 of the lever 2c is in contact with the support arm 2a2 of the handle body 2a, so that the swing trajectory of the lever 2c can be optimized.

[0093] The needle shaft 2d is a short cylinder with a radial through hole 2d1 for accommodating the transverse section of the measuring needle 1 and allowing it to slide freely therein. The lever head 2c4 is provided with a through hole 2c2 and a slot 2c3 that penetrate from top to bottom. Two concentric needle shaft holes 2c8 are provided inside the lever head 2c4, i.e., on both sides of the slot 2c3, for accommodating the needle shaft 2d, in which it can rotate freely. The inclined surfaces 2c9 on both sides of the slot 2c3 are provided to enable the needle shaft 2d to be pushed in more easily. When making the needle shaft hole 2c8, one side thereof, i.e., one side of the slot 2c3, can be a through hole, which can be blocked by gluing with the same material after making. Therefore, the needle shaft 2d can also be put into this through hole first and then blocked. Specific implementation method three:

[0095] like Figure 1 — Fig.44 As shown, an intraoral peeping detection and measurement device is shown, the knob 3 comprises a knob body 3a and a snap ring 3b, a stepped hole is arranged in the knob body 3a, the stepped hole is composed of a small cylindrical hole 3a1 and a large cylindrical hole 3a2, an annular groove 3a3 and a plurality of straight arc grooves 3a4 are arranged on the large cylindrical hole, the plurality of straight arc grooves 3a4 are uniformly distributed on the inner surface of the large cylindrical hole 3a2 along the axial direction, the snap ring 3b is an annular member, a plurality of hooks 3b4 with barbs are arranged on one end face of the snap ring 3b, the plurality of hooks 3b4 are formed by segmenting the same gyroid, a plurality of arc internal threads 3b2 are arranged on the inner cylindrical surface of the snap ring 3b, a plurality of straight arc edges 3b3 are arranged on the outer cylindrical surface of the snap ring 3b, the plurality of straight arc edges 3b3 respectively correspond to the plurality of arc internal threads 3b2 in the knob body 31.

[0096] The working principle and beneficial effects of this embodiment are as follows: according to the structure of the knob 3, once the snap ring 3b is pressed into the knob body 3a, the snap ring 3b can no longer be taken out and can only be removed after being cut off. In this way, the knob 3 can be sleeved on the knob nut 4e without being separated from the nut, but can rotate freely on the knob nut 4e. When the knob 3 needs to be removed, the snap ring 3b is cut off and removed, and then a pin wrench (not belonging to the present invention) is used to insert the pin on the pin wrench into the wrench hole 4e1 of the knob nut 4e to remove it, and the knob body 3a can be removed.

[0097] Fig.15 and 16 The overall structural features of the body 4 after the top cover 4v and all the components below it are removed are shown, wherein the silicone plug 4g is inserted only after the assembly is completed to play a role in dust protection, while Fig.17 — Fig. 20In the figure, the structural features of the box body 4a and its components, as well as the connection relationship between them, are shown, including the knob nut 4e. The two loading holes 4a4 are only used to load the screws 4f. Once the loading is completed, the support 4b, the spring 4c and the piston shaft 4d are connected in the box body, and the silicone plug 4g can be used to plug them. The connection sequence is: first insert the spring 4c, then the piston shaft 4d, then load one of the two screws 4f to align with the hole 4a4 and merge it into the support with the screw to tighten it, and then load the other screw 4f to align with the other hole 4a4. The plane 4d2 on the piston shaft 4d is used to place the support 4b. This plane can also be made into a boundary shape consistent with the contour of the support 4b. Specific implementation method four:

[0099] like Figure 1 — Fig.44 As shown, an intraoral inspection and measurement device, the body 4 includes a box 4a, a support 4b, a spring 4c, a piston shaft 4d, a knob nut 4e, a knob screw 1 4f, a silicone plug 4g, an end cover screw 4h, an end cover 4i, a knob screw 2 4j, a wire hoop 4k, a positioning pin 4m, a moving grid seat 4n, a knob screw 3 4p, a moving grid 4q, a circuit board seat 4r, a knob screw 4 4s, a knob screw 5 4t, a circuit board 4u and a top cover 4v;

[0100] The piston shaft 4d is connected to the pillar 4b inside the box body 4a through a knob screw 4f threaded fit, the pillar 4b is connected to the moving grid seat 4n through a knob screw 4p, the moving grid 4q is bonded to the moving grid seat 4n, the box body 4a is threadedly connected to the circuit board seat 4r through a knob screw 4s, the positioning pin 4m is arranged in the pin hole 4a7 and inserted into the circuit board seat 4r, the circuit board 4u is threadedly connected to the circuit board seat 4r through multiple knob screws 4t, the cable 5 passes through the end cover 4i to be electrically connected to the circuit board 4u, and a top cover 4v is arranged on the box body 4a.

[0101] The working principle and beneficial effects of this embodiment are as follows: a moving grid seat 4n is arranged on the pillar 4b of the machine body 4 and fixed by a screw 4p. It itself contains a structure to prevent rotation and can therefore be well constrained. A moving grid 4q is arranged on the moving grid seat 4n and is bonded and fixed. Therefore, when the pillar 4b moves, the moving grid 4q moves together. The moving grid 4q is an electronic distance measuring component and is one of the two paired electronic distance measuring components here. The other is a circuit board 4u containing a distance measuring static grid, also called a "fixed grid". The two together are a miniature displacement sensor. Although there are small grating scales for grating displacement sensors, they are still difficult to meet the application requirements here. Therefore, the invention adopts a capacitive grid displacement sensor. At this time, the moving grid 4q is a reflective grid-shaped electrode plate of the capacitive grid displacement sensor. A blank printed circuit board with regular arrangement and shape without electronic components, and the circuit board 4u is a static grid circuit board containing a distance measuring capacitor group and other electronic components. The circuit board holder 4r supporting the circuit board 4u is placed on the top surface of the box 4a and fixed with two knob screws 4s and a positioning pin 4m. The capacitive grid displacement sensor can adopt the small TM003A capacitive grid displacement sensor provided by Guilin Tianmu Measurement and Control Technology Co., Ltd., or the enhanced model of TM003A with appropriately reduced size. It can have a variety of signal output modes, and each data ends with a carriage return character CR, one of the standard computer information exchange codes. After being captured and converted into a signal that meets the USB standard by the relay box 6, it is transmitted to the online computer with the USB keyboard output data specification.

[0102] The present invention uses a lever 2c with a lever ratio of 3.5-5.5. For example, assuming that the probe length is 10 mm, when the lever ratio is 4, it means that the maximum effective stroke Smax indicated by the push rod 2b will be:

[0103] Smax=10 / 4=2.5mm

[0104] That is, when the 10 mm long stylus 1 is completely retracted into the needle sleeve 1a Figure 2 and Figure 4 When the indicator is within the range, the push rod 2 moves 2.5 mm.

[0105] A miniature magnetic grating displacement sensor of the Hall array type can also be selected. When using a miniature Hall magnetic grating displacement sensor, the moving grating 4q is a magnetic stripe magnetic scale, and the Hall displacement detection circuit is a circuit board 4u containing a Hall array integrated circuit and other electronic components, which is equivalent to a static grating / fixed grating. At this time, it is advisable to adopt a type with a detection distance ≥ 4mm to ensure that the detection distance can cover the effective stroke indicated in the pillar 4b. The output data technical specifications of this magnetic grating displacement sensor detection circuit board must be compatible with TM003A, so the relay circuit board in the relay box 6 is shared. Specific implementation method five:

[0107] like Figure 1 — Fig.44As shown, an intraoral peeking detection and measurement device is provided, wherein the box body 4a is in the shape of a rectangular parallelepiped, a hollow stud 4a8 is provided on one end of the box body 4a, a piston shaft hole 4a3 which is cocentric with the hollow stud 4a8 is provided in the box body 4a, a stop step 4a5 is provided on the inner wall of the hollow stud 4a8, the stop step 4a5 is in contact with the end face 2a8 of the handle body 2a, the stop step 4a5 is used for limiting the position of the handle 2 when it is connected to the body 4, a support hole 4a1 with semicircular ends is provided on the top surface of the box body 4a, the support hole 4a1 is used for limiting that the support 4b is connected to the piston shaft 4d through a knob screw 4f threadedly matched, and the knob nut 4e is connected to the hollow stud 4a8 through a threaded match; the retaining ring 3b is squeezed into the torsion body 3a by rotating the knob nut 4e.

[0108] The working principle and beneficial effects of this embodiment are as follows: According to the lever balance condition in mechanics, the structural characteristics of the lever 2c of the present invention have the following relationship:

[0109] F1·L1=F2·L2

[0110] Among them, F1 is the long arm force of the lever 10, L1 is the long arm length of the lever 16, while F2 is the short arm force of the lever 13, L2 is the short arm length 14. The force and the lever arm are perpendicular to the mechanical principle, so:

[0111] F2=(L1 / L2)·F1, or F1=(L2 / L1)·F2

[0112] L1 / L2 is the "lever ratio". Since the long arm L1 of the lever is larger than the short arm L2, L1 / L2 is a number greater than 1, and its reciprocal L2 / L1 is a number less than 1. The actual force and the lever arm are not always perpendicular, but the average value of the angle between them is very small and approximately perpendicular, so they can be calculated as perpendicular. That is, directly use F1 and F2, L1 and L2 represent the lever arm length or lever arm, and the angle between the two can be 90 degrees or close to 90 degrees. The above calculation formula means that the top rod 2c Figure 4 The thrust F2 indicated in the figure is L1 / L2 times the thrust F1 of the probe 1. As mentioned above, the present invention takes the lever ratio between 3.5-5.5. When the lever ratio is 4, the thrust of the push rod is:

[0113] F2=(L1 / L2)·F1=4·F1

[0114] Because the probe thrust F1, i.e. the force of the probe inserting into the periodontal pocket, has requirements and must be between 10-20 grams, therefore, when the probe thrust F1 is 10 grams, there is still the push rod thrust F2:

[0115] F2=4×10=40 grams force

[0116] This 40 grams of force will be provided by the spring 4c Fig.10 , Fig.11 There are instructions to provide see "Example 7", similarly, by Fig.15 The geometric relationship shown in (D) can easily obtain the following displacement distance relationship:

[0117] Re:S=L1:L2 or Re / S=L1 / L2 The principle of similar triangles in geometry

[0118] Where Re is the distance 18 that the measuring needle retreats, S is the distance 18a that the push rod 2b pushes forward, L1 is the length of the long arm of the lever 16, and L2 is the length of the short arm of the lever 14, so:

[0119] S=(L2 / L1)·Re

[0120] Among them, L2 / L1 is the inverse of the leverage ratio, and its maximum value Smax is:

[0121] Smax=(L2 / L1)·Ln

[0122] Where Ln is the length of the probe 17, that is, the longest extension distance. When the lever ratio L1 / L2=4, we have:

[0123] Smax=(1 / 4)·Remax, and Remax=Ln

[0124] That is, at this time, the maximum push distance Smax of the push rod is only 1 / 4 times the maximum retraction distance Remax of the probe, that is, the reciprocal times of the lever ratio. The maximum retraction distance of the probe is when the probe 1 is completely retracted into the needle sleeve 1a. Figure 2 , Figure 4 The total retreat distance when there is an indication is equal to the probe length Ln. Therefore, the measured distance Dp is Fig.15 The reference number 19 indicated in the figure is related to:

[0125] Dp=Ln–Re

[0126] Where Dp is the measured distance, i.e. the depth / length of the hole to be measured, which is the required value 19, Ln is the probe length 17, and Re is the retreat distance 18. When the probe length is 10, the measured distance is:

[0127] Dp=10-Re

[0128] The above formula is a calculation formula for measuring the distance Dp. The length actually measured by the electronic distance measuring system of the present invention is the distance Re of the measuring needle retreat, which must be converted into the measuring distance Dp in the application program.

[0129] The diagram shows the formation of the main error of the analytical probe 20 on the lever 2c, which is used in the prior art. Since the analytical probe 20 is hinged to the lever 2c, that is, one end of the analytical probe 20 will rotate around the lever 2c head, and the lever 2c also rotates and swings around its fulcrum axis to form an arc-shaped reciprocating lever swing trajectory 24, when the analytical probe 20 is in the middle position 22 and remains in a vertical state, it cannot be in the probe guide hole 31 on the arm head 21. Assuming that the diameter of this guide hole just fits the analytical probe 20, it will deviate from the guide hole 31. The solution is to enlarge the stylus guide hole 31 so that it can accommodate the stylus even when the analysis stylus 20 is in a tilted state when it is in the middle position 22. The middle position 22 is the farthest distance in the lever track from the center of the stylus guide hole 31. At this time, the analysis stylus 20 is tilted in the stylus guide hole 31 instead of being in a vertical state, that is, it cannot be parallel to the measured distance, which will cause an error. The error generated is the difference between the distance value measured when the true value stylus guide hole 31 is parallel to the measured distance and the measured value when the stylus guide hole 31 is tilted.

[0130] When the lever 2c is in the upper position 23 and the lower position 29, the analysis probe 20 can be in a vertical state and just aligned with the probe guide hole 31. At this time, the needle posture of the analysis probe 20 remains parallel to the measured distance, so no error caused by tilting will occur. The other positions of the analysis probe 20 are in a tilted state, and the degree of tilting at each position is different. For the hinged push rod 25, similarly, if the push rod 25 also adopts a linear sliding structure, the error caused by tilting can be eliminated or reduced.

[0131] The present invention does not use an articulated measuring needle and an articulated ejector rod, so the error caused by tilting is greatly reduced. Specific implementation method six:

[0133] like Figure 1 — Fig.44 As shown, an oral intraocular peeking detection and measurement device, the box body 4a is set as a short box body, the piston shaft hole 4a3 in the box body 4a is set through both ends of the box body 4a, and hollow studs 4a8 and spring cylinders 34 are respectively set at both ends of the box body 4a, the hollow studs 4a8 and the spring cylinders 34 are connected, and the spring cylinders 34 are provided with springs 4c and screw plugs 35. The spring 4c is sleeved on the piston shaft 4d and connected to the spring cylinders 34 by threaded fitting, and the spring cylinders 34 are connected to the box body 4a by threaded fitting.

[0134] The working principle and beneficial effects of this embodiment are as follows: the short chassis 33 of the present invention is the chassis 4 Fig.34 , Fig.35There is a shortened form indicated therein, that is, the spring 4c is accommodated in a spring barrel 34 arranged on the right side of the box body, and the spring barrel 34 is connected to the box body by a thread. At the same time, the spring barrel 34 is closed at the other end by a screw plug 35. This screw plug 35 can be used to adjust the elastic force. The elastic force increases when it is screwed in, and the elastic force decreases when it is screwed out. At the same time, it is also convenient to replace the spring 4c, which can reduce the volume of the box body and reduce the weight, because the box body 4a has an indication or the box body 33 is made of metal. In addition, with the help of the spring barrel, it is easier to select a longer spring 4c, so as to obtain a smaller range of elastic force, that is, the insertion force of the probe 1.

[0135] According to the elastic force formula in engineering mechanics:

[0136] F=k·x

[0137] Among them, F is the elastic force of the spring, k is the spring stiffness, also known as the spring coefficient, and x is the change in spring length. For compression springs, x is the amount of spring shortening, and the spring stiffness k has units, which can be gf / mm, that is, gram-force / millimeter. The unit of force is gf, which means "gram-force", that is, it is not a unit of weight but a unit of force. For example, when the compression spring's k=10gf / mm, it means that for every 1 mm of compression, the elastic force increases by 10 grams.

[0138] From the elastic force formula, we know that if the spring stiffness k is smaller, the same length change x will cause a smaller change in elastic force. For example, when k = 10gf / mm, a 35mm long spring has an elastic force after being compressed by 5mm:

[0139] F = k·x = 10×5 = 50 grams of force

[0140] When k = 5gf / mm, the elastic force of the same 35mm long spring after compression of 5mm is:

[0141] F = k·x = 5×5 = 25 grams of force

[0142] To achieve 50 g-force, the latter needs to be compressed by 10 mm instead of 5 mm. This is the basis for the present invention to control the insertion force of the measuring needle, that is, the spring stiffness should be small and the compression amount should also be small.

[0143] One of the spring selection embodiments:

[0144] Select a compression spring with spring stiffness k = 10gf / mm, length 40mm, pre-compression 5mm, that is, spring 4c is correctly installed in box 4a Fig.10 , Fig.11 The amount of compression after the indication is 5mm, that is, the length of the spring in the box is 35mm, then the spring can provide elastic force:

[0145] F = k x = 10 x 5 = 50 gf, where x = 5 mm

[0146] From the above, when the lever ratio is 4, the probe 1 Figure 2 , Figure 4 The thrust on the indicated side is:

[0147] Probe starting force = 50 / 4 = 12.5 g-force

[0148] When the measuring needle is pushed and completely withdrawn into the needle sleeve 1a Figure 2 , Figure 4 When the indication is in the middle, if the probe length Ln is taken Fig.15 When the indication is 10mm and the lever ratio is 4, the push rod 2b and the piston shaft 4d Figure 4 , Fig.10 The indicator is pushed and moves 2.5mm, so the spring is compressed again.

[0149] The spring force is 2.5 mm, so the total compression is 5 + 2.5 = 7.5 mm.

[0150] F = k x = 10 x 7.5 = 75 gf, where x = 7.5 mm

[0151] The thrust at the end point of the probe is:

[0152] Probe end point thrust = 75 / 4 = 18.5 g-f

[0153] That is, the force for pushing the probe into the periodontal pocket is between 12.25-18.75 grams of force, which meets the insertion force requirement for the probe for probing the periodontal pocket, which is required to be within the range of 10-20 grams of force.

[0154] Spring selection embodiment 2:

[0155] Select a compression spring with spring stiffness k = 3gf / mm, length 60mm, pre-compression 20mm, that is, spring 4c is correctly installed in box 4a Fig.10 , Fig.11 There is an indication in the figure, or the compression of the short case after 33 li is 20 mm, that is, the length of the spring in the case is 40 mm, then the spring can provide elastic force:

[0156] F = k·x = 3×20 = 60gf

[0157] From the above, when the lever ratio is 4, the probe 1 Figure 2 , Figure 4 The thrust on the indicated side is:

[0158] Probe starting force = 60 / 4 = 15 g-force

[0159] When the measuring needle is pushed and completely withdrawn into the needle sleeve 1a Figure 2 , Figure 4 When the indicator is in the middle, take the probe length Ln Fig.15 When the indication is 10mm and the lever ratio is 4, the push rod 2b and the piston shaft 4d Figure 4 , Fig.10 , it is pushed and moves 2.5mm, so the spring is compressed by another 2.5mm. The total compression is 20+2.5=22.5mm. The spring force is:

[0160] F = k·x = 10 × 22.5 = 67.5 gf

[0161] So the thrust at the end point on the stylus side is:

[0162] The probe end point thrust = 67.5 / 4 = 16.875 g-f ≈ 16.9 g-f. Specific implementation method seven:

[0164] like Figure 1 — Fig.44 As shown, an intraoral video detection and measurement device, the measuring needle 1 comprises a needle sleeve 1a, the shape of the needle sleeve 1a is a two-stage cylindrical shape, the cylinders at both ends of the needle sleeve 1a are respectively a needle tube 1a1 and an upper cylinder 1a3, a transition cone is arranged between the needle tube 1a1 and the upper cylinder 1a3, the needle tube 1a1 and the cylinder 1a3 are both hollow structures, the needle tube 1a1 and the upper cylinder 1a3 are respectively penetrated by a small hole 1a6 and a large hole 1a5, the middle end of the needle sleeve 1a is provided with an annular groove waist 1a2, the upper cylinder 1a3 is provided with an axial groove 1a4, the needle sleeve 1a is inserted into the needle sleeve hole 2a1 of the handle body 2a through the upper cylinder 1a3 and the annular groove waist 1a2, the needle sleeve 1a is clamped in the needle sleeve hole 2a1 through the annular groove waist 1a2, and the outer wall of the needle tube 1a1 is provided with a rectangular thin radial side wing 1a7;

[0165] The measuring needle 1 is provided with a needle sleeve removal tool 32, and a large long groove 32b and a small long groove 32d are provided in the needle sleeve removal tool 32. The measuring needle 1 is inserted into the large long groove 32b and the small long groove 32d. A sleeve pressing protrusion 32e is provided on the bottom surface of the needle sleeve removal tool 32, and the sleeve pressing protrusion 32e is loosely fitted in the needle sleeve hole 2a1.

[0166] The working principle and beneficial effects of the present embodiment are as follows: that is, the periodontal pocket insertion force of the probe 1 is between 15-16.9 grams-force, and the minimum and maximum difference is only 1.9 grams-force, which not only meets the insertion force requirement for periodontal pocket exploration, but also has a smaller and better size difference than the previous example. Since the depth of periodontal pockets is mostly between 3.5-7mm clinically, the retraction distance Re of the probe 1 is mainly in the range of 3-6.5mm, that is, between 0-6.5mm. Therefore, in this depth range, the insertion force of the probe 1 has a smaller variation range, and the insertion force can be considered to be "unchanged", that is, approximately unchanged.

[0167] Therefore, the short case 33 of the present invention is more advantageous for selecting a longer spring 4c. Such a spring 4c can be called a "differential spring", which means "a spring that can be used to obtain a differential of elastic force", where "differential" is a mathematical concept, meaning "a tiny amount". How small is it? Saying "how small it can be" is relative. In practical applications, a relatively tiny amount can be considered as a "differential". For example, if there is a length of 100 mm, when 5 mm is extracted from it, this 5 mm length can be regarded as a "differential" of the 100 mm length. Therefore, "differential" in practical applications means "a small portion taken from the whole", which is required to be small enough.

[0168] As mentioned above, when the spring 4c of the present invention is compressed by 2.5mm in the box body, the compression of 2.5mm is the initial length of the spring 4c, that is, the length in the box body, which is a "length differential" of the original length of the spring 4c in the free state minus the pre-compression amount, and the increase in elastic force generated by this length differential is the "elastic force differential". For example, the 1.9 gram force change in the above-mentioned "Second Embodiment of Spring Selection" is an elastic force differential in this case. The smaller the elastic force differential, the better, but it cannot be zero. The smaller it is, the smaller the range of elastic force change in the entire stroke of the probe 1. When it is small to a certain extent, it can be considered as "invariable" or "constant force", which means approximately constant force.

[0169] To this end, there are two measures: one is to increase the lever ratio L1 / L2, and the other is to reduce the spring stiffness value, that is, the k coefficient, also known as the "spring coefficient". The spring stiffness is related to the elastic characteristics of the spring wire material, the spring wire diameter, the spring diameter, the spring pitch and other factors. The stronger the elasticity of the spring wire material, the higher the hardness. The thicker the spring wire diameter, the greater the spring stiffness. The pitch refers to the axial advancement distance of the spring wire when it rotates one circle along the spiral path, which is the "height of one circle", which is consistent with the meaning of "pitch". The following examples do not belong to the content of the preferred embodiment of the present invention and are only used to illustrate the general characteristics of the spring:

[0170] Assuming that the diameter of the spring wire is 1mm and the pitch is twice the diameter of the spring wire, that is, 2mm, it means that the gap between the spring wires is also 1mm wide. The spring has a total of 20 turns, so the spring length is 2×20=40mm. Therefore, when the spring is compressed by 20mm, the spring length becomes 20mm. At the same time, the gap between the spring wires is completely eliminated and compacted, so it can no longer be compressed, that is, a "length differential" can no longer be generated in this state. Therefore, the maximum compression of such a spring structure is 20mm. Although the spring wire is still in the elastic range when the length is shortened due to the compression of the spring, there is no room for the spring to shorten further.

[0171] In addition, according to the principles of engineering mechanics, materials science and mechanics, compression springs are only used to bear pressure during work. The shortening of length after compression mainly comes from the torsional deformation of the spring wire around its own axis, and this torsional deformation is limited and only occurs within a very small force range. Permanent deformation will occur after exceeding the force range. At this time, even if the pressure is released, it cannot return to its original state or bounce back. When the compressed length of the spring becomes shorter, the overall deformation is the accumulated total of the torsional deformation of the spring wire at various locations, or in other words, each cross section, or each small segment. Therefore, the longer the spring wire, that is, the more turns it has or the larger the spring diameter, the smaller the torsional deformation allocated to each cross section or each small segment. Therefore, it can be more guaranteed that the elastic limit of the torsional deformation of the spring wire will not be exceeded, and the spring will work more reliably and stably.

[0172] The present invention takes the lever ratio to be between 3.5 and 5.5, takes the spring stiffness to be between 3 and 10 gf / mm, takes the spring pitch to be between 2 and 5 times the spring wire diameter, takes the initial length of the spring, i.e., the length after pre-compression in the body 4, to be at least 12 times the maximum effective stroke of the piston shaft 4d, i.e., the length differential of the spring, and the proportional relationship between the two is:

[0173] Spring initial length: piston shaft maximum effective stroke ≥12:1

[0174] Furthermore, typical values ​​of the preferred embodiment of the present invention are: lever ratio = 4, spring stiffness = 3-10 gf / mm, spring twist = 3 times the spring wire diameter, spring initial length = 40 mm, and probe length = 10 mm.

[0175] The above-mentioned "maximum effective stroke of the piston shaft" ≠ the maximum stroke of the piston shaft, that is, the maximum assembly stroke. The former is equal to the maximum pushing distance of the push rod, and the latter is larger than the former in order to facilitate assembly and debugging. Specific implementation eight:

[0177] like Figure 1 — Fig.44As shown, an intraoral inspection and measurement device is provided, wherein the relay box 6 is provided with a zero point socket 7 and a collection socket 8, and the relay box 6 is connected with a transmission line and a USB plug 9; a relay circuit board is provided in the relay box 6, and the relay circuit board is connected to the circuit board 4u in the body 4 through a cable 5, and the relay circuit board is electrically connected to the foot switch of the relay box 6 through the collection socket 8, and the distance measurement data of the circuit board 4u is collected by the relay box 6 and then sent through the USB transmission line.

[0178] The working principle and beneficial effects of this embodiment are as follows: The depth of the periodontal pocket 36, the depth of the caries pit 37, and the skewness of the crooked tooth 38 are measured by using the present invention. The needle sleeve removal tool 32 of the present invention can be used to conveniently remove the needle sleeves 1a and 1b, the latter of which is provided with a side wing 1b7. Fig.14 The needle sleeve type with an indication is convenient for measuring the hard tissue of the tooth, because the side wing 1b7 is easier to find and lean against the hard measurement benchmark. The "benchmark" refers to the measurement starting point. When measuring the periodontal pocket, hold the handle 2 and use the probe 1 to gently push the gums apart, and carefully and slowly insert the probe 1 into the periodontal pocket. At this time, the entire handle 2 moves together. When the resistance encountered by the probe is greater than or equal to the measurement force, i.e., the insertion force, the probe 1 will stop moving and inserting, but the rest of the handle 2 will continue to move until the lower edge of the needle sleeve 1a touches the gums. At this time, the insertion action must be stopped immediately, and the data acquisition pedal switch must be pressed for data acquisition. The process of measuring hard tissue is similar to this;

[0179] The present invention can utilize MS-Excel spreadsheets for data collection and processing, that is, the present invention can be directly connected to a personal computer, i.e., a Windows computer, and, without any driver and special application software, only public office software with calculation functions can be used for periodontal pocket exploration, or other oral measurement data collection, analysis and report output. For example, using the MS-Excel spreadsheet software in the MS-Office software group, there are many cells arranged vertically and horizontally in this table, and each cell has a unique address, i.e., a cell address, which is composed of letter codes A, B, C... on the top of the table and number codes 1, 2, 3... on the left side of the table, with letters in front. For example, cell D6 is the cell where cursor 40 is located. Note that the "cursor" here is not the same as the mouse arrow. The "cursor" here refers to the cell cursor. The cell where the cursor is located will be highlighted and in an editable state. You can click a cell with the mouse arrow to position the cursor in this cell.

[0180] MS-Excel spreadsheets are composed of many cells arranged vertically and horizontally. Each such table is a worksheet. Each cell can input 4 types of information, which are:

[0181] ⑴The value is composed of positive and negative signs, numbers and decimal points;

[0182] ⑵ Character words, symbols, and numbers themselves can also belong to the character class;

[0183] ⑶Address other cells, which can come from other worksheets or Excel files;

[0184] ⑷Formula calculation or procedure.

[0185] The top of the Excel table shows the contents of cell D6 where cursor 40 is located, namely:

[0186] D6=10-C6

[0187] C6 is the address of another cell, on the left of D6. This is the conversion formula for the collected data. As mentioned above, the total length of the indicated length of the probe 1 is taken as 10 mm, and the collected measurement data is the retraction distance Re of the probe. The required periodontal pocket depth is displayed in the position of the cursor 40 in cell D6, because the above calculation formula has been entered in this cell. When data is entered in cell C6, D6 will automatically calculate and display the calculation result, and the formula is only displayed in the input column 39. PD=Pocket Depth in the table is the periodontal pocket depth.

[0188] Furthermore, multiple worksheets can be used, one of which is used as the original data recording table. In this case, the collector locates the first cell, and then can collect all the way until the last time, without doing any operation on the table during the period, because the relay box 6 of the present invention Figure 2 There is an instruction that every data sent to the computer ends with a carriage return character CR, which is one of the standard computer information exchange codes. Its function is to receive and end input. Therefore, when Excel detects CR information, it automatically receives and ends the current input and prepares for the next reception, that is, it automatically jumps to a cell below. For example, after receiving C6, it automatically jumps to cell C7, and then uses other worksheets for data processing and report output. The original collected data required by these worksheets, and its address information is entered into the required places in these worksheets, just like Fig.44 Just like the cell D6 where the cursor is located, other diagnostic information records can also be added, such as bleeding, pain, severe inflammation, etc., and even analysis charts can be added, which is what Excel software excels at.

[0189] Furthermore, you can do secondary development on Excel and build a special acquisition program that runs in the Excel environment. You can set the user interface, including menus, buttons, etc., and have management and output functions such as patient information, exploration records, formal reports, and archives. MS-Excel has powerful secondary development functions, which can be used for simple development or complete development. Users can do simple development themselves. When using probes of different lengths, they only need to enter their actual values ​​into the Excel conversion formula.

[0190] By means of the elastic force control measure of the present invention, a measuring force, i.e., an insertion force, which varies very little within the range of the measuring needle stroke and is approximately constant, can be obtained, and the soft and hard tissues in the oral cavity can be measured with high measurement accuracy. The needle sleeve removal tool of the present invention can be used to conveniently remove the needle sleeve. The needle sleeve with side wings of the present invention can be used in combination with measuring needles of different lengths to measure the hard tissues of the teeth. Special diagnosis and measurement software can be used, or public office programs can be used instead, and the conversion of collected data can be conveniently and simply realized in the software.

[0191] Spreadsheet software, since the measurement result data sent by the relay box 6 contains the CR symbol, Excel automatically completes the input immediately after receiving it, and the cursor automatically moves downward to locate in a cell below. At the same time, it is ready to receive the next measurement data. This is exactly the role of the carriage return character CR. Therefore, as long as the first cell is located and the order of receiving data is planned from top to bottom in the Excel table, the acquisition process can be automatically recorded without operating the table until the last data is received. Specific implementation method nine:

[0193] like Fig.39 — Fig.43 As shown, an intraoral camera detection and measurement device, the style former 41 includes an upper tooth former 42 and a lower tooth former 43, the upper tooth former 42 and the lower tooth former 43 have the same structure and connection method, the upper tooth former 42 and the lower tooth former 43 are slidably connected with each other and a buffer clip 44 is provided, and a spring is provided in the buffer clip 44 between the upper tooth former 42 and the lower tooth former 43;
