Description

Technical Field

[0001] The present invention belongs to the technical field of oral medical auxiliary instruments, and particularly relates to an orthodontic force measuring attachment, and also relates to an orthodontic holding forceps with a force measuring function provided with the above-mentioned orthodontic force measuring attachment. Background Art

[0002] Fixed orthodontics is a commonly used orthodontic technique for treating malocclusions. After the brackets are cemented to the tooth surface, the arch wire is inserted into the slot of the bracket, and the force generated by the deformation of the arch wire is transmitted to the tooth through the bracket to achieve tooth movement. In addition to the force generated by the deformation of the arch wire, force application devices such as extension springs and elastic rings are used to directly apply forces in different directions and of different magnitudes to the teeth to achieve tooth movement. After the extension springs, elastic rings and other force application devices are stretched, one end is connected to the bracket on the tooth, and the other end is connected to the bracket on another tooth or fixed to the traction hook on the arch wire. The orthodontic force generated after the above-mentioned force application device is stretched is transmitted to the tooth, causing the tooth to move.

[0003] Different tooth movement requirements require different orthodontic forces to achieve, and different teeth require different orthodontic forces to be able to move. Therefore, when using the above-mentioned force application device to apply orthodontic force, it is necessary to stretch the extension spring or elastic ring to different lengths so that it can exert different orthodontic forces required to move specific teeth. In the actual orthodontic clinical diagnosis and treatment process, most operators stretch the extension springs, elastic rings and other force application devices and apply force to the teeth by experience. This force application method is often not accurate enough to enable the teeth to obtain the accurate force required for their movement. If the force is too small, the teeth cannot move or move too slowly, affecting the orthodontic efficiency. If the force is too large, the tooth movement exceeds the expectation, affecting the final orthodontic effect.

[0004] Some manufacturers have introduced orthodontic force gauges. Their structure is pen-shaped, and the tip can hook one end of a force application device such as an extension spring or an elastic ring. There is a calibrated spring inside. After stretching the extension spring or elastic ring, it can display the magnitude of the force on the spring immediately. This force gauge is used to help doctors pre-confirm the force values at different stretching lengths of the force application device. However, during the actual in-mouth force application process, only the holding forceps can be used to clamp the extension spring or elastic ring, stretch it and fix it to the bracket or traction hook on the other side. At this time, it is still only possible to roughly estimate its elongation length by the naked eye, and the orthodontic force finally applied to the teeth is still not accurate enough.

[0005] Chinese patents CN211325744 U and CN216417359 U respectively disclose a force measuring clamp for orthodontics. By embedding a force measuring spring in the orthodontic clamping forceps, the force measuring step is combined with the in - mouth operation step. When using the force measuring clamp, the measurement of the orthodontic force and the subsequent force application operation can be completed simultaneously. However, both of the above two force measuring clamping forceps have common deficiencies. First, the orthodontic clamping forceps are instruments used in the oral cavity and need to be "sterilized for each use by one person". The fine structures such as the force measuring spring in the clamping forceps are prone to aging or damage during the sterilization process, affecting the effect. Second, during the actual force measurement process, the force line transmitted from the beak of the clamping forceps is located on the angular bisector of the two handles of the clamping forceps. In the above two patents, the force measuring spring is placed in one of the handles, and the force measuring direction of the spring does not coincide with the actual force line, resulting in inaccurate measured force values. Finally, when operating the above two force measuring clamping forceps, the operator needs to judge the magnitude of the force value by visual observation, which not only has low efficiency but also easily distracts the operator's attention from the orthodontic operation, affecting the orthodontic effect.

[0006] Based on the above existing problems, the present invention provides a detachable orthodontic force measuring accessory to ensure accurate and efficient orthodontic force application operation. Summary of the Invention

[0007] One of the purposes of the present invention is to provide an orthodontic force measuring accessory with good adaptability to orthodontic forceps, easy to install and adjust, and capable of accurately feedbacking the magnitude of the applied force.

[0008] Another purpose of the present invention is to provide an orthodontic clamping forceps with a force measuring function that can accurately feedback the magnitude of the applied force and can avoid damage to the force measuring accessory during the disinfection and sterilization operation process.

[0009] The technical solution adopted by the present invention to achieve the first purpose is: to provide an orthodontic force measuring accessory, which is characterized by including: a guide rail, a sliding member, and a clamping portion; The guide rail includes a spring, a scale line, and a first scale indicating member; the spring is arranged inside the guide rail, one end of the spring is fixed to the end of the guide rail, and the other end is connected to the sliding member; the sliding member moves along the guide rail under an external force and compresses the spring; when the sliding member moves to the target position, under the action of the first scale indicating member, the second scale indicating member of the sliding member generates relative movement with respect to the sliding member; the clamping portion includes an L - shaped splint, one end of the L - shaped splint is connected to the outer side wall of the guide rail, and the other end is provided with a locking member; an elastic cushion block is arranged between the L - shaped splint and the outer side wall of the guide rail, and by adjusting the locking member to squeeze the elastic cushion block to generate different degrees of deformation, the clamping angle of the clamping portion with respect to the base body can be adjusted.

[0010] On the basis of the above technical solution, in the guide rail, there are multiple first scale prompt members, which respectively correspond to the scales of the scale lines; the first scale prompt member includes a fixing part and a movable blocking block.

[0011] On the basis of the above technical solution, the fixing part is installed on the side wall of the guide rail, and the top of the movable blocking block can protrude from the fixing part by a certain height, and when the sliding part moves to the scale where the movable blocking block is located, it blocks the second scale prompt member of the sliding part.

[0012] On the basis of the above technical solution, the movable blocking block is slidably connected to the fixing part, and the fixing part is sleeved on the middle part of the movable blocking block. When the top of the movable blocking block protrudes from the fixing part by a certain height, the bottom of the movable blocking block is magnetically connected to the fixing part.

[0013] On the basis of the above technical solution, the sliding part includes a small ball, a first finger pinching plate and a second finger pinching plate; the first finger pinching plate and the second finger pinching plate are respectively located outside the guide rail above and below the small ball, and are connected to the small ball through a connecting rod.

[0014] On the basis of the above technical solution, the first finger pinching plate includes a substrate and a second scale prompt member. The second scale prompt member includes a free part arranged on the side of the substrate and a small spring located between the free part and the substrate. In the normal state, the free part and the substrate are in the same plane; when the free part contacts the movable blocking block at the target scale, the free part deflects relative to the substrate after being stressed, playing a prompting role, and then can return to the initial position under the action of the small spring.

[0015] On the basis of the above technical solution, the L-shaped clamping plate includes a first clamping plate and a second clamping plate. The first clamping plate is in the shape of a right trapezoid, its right-angled waist is connected to the second clamping plate, and its oblique waist is connected to the outer side wall of the guide rail; the locking member is a pair of screws arranged on the second clamping plate.

[0016] On the basis of the above technical solution, the elastic cushion block is a prismatic rubber block with right trapezoidal upper and lower bottom surfaces; in the rubber block, the side surface connected to the oblique waists of the upper and lower bottom surfaces of the right trapezoid is fixed to the outer side wall of the guide rail; the rubber block and the first clamping plate and the second clamping plate enclose a U-shaped clamping space. Further, in the U-shaped clamping space, the inner walls of the rubber block and the first clamping plate and the second clamping plate are all rough surfaces to increase the friction force between the clamping member and the clamping arm of the orthodontic clamping pliers during the clamping process and improve the installation stability.

[0017] On the basis of the above technical solution, the force measurement range of the orthodontic force measurement accessory is 50g - 500g, and the scale of the guide rail corresponds to the force value when the spring is compressed to the position where it is located, that is, the applied force value actually measured by the orthodontic force measurement accessory.

[0018] The second technical solution adopted to achieve the purpose of the present invention is: to provide an orthodontic clamping forceps with a force measuring function, including an orthodontic clamping forceps and an orthodontic force measuring accessory according to the first purpose of the present invention; the orthodontic force measuring accessory is installed at the proximal handle end of one side of the orthodontic clamping forceps, and the long axis of the orthodontic force measuring accessory is collinear with the central axis of the orthodontic clamping forceps.

[0019] Based on the above technical solution, before the orthodontic clamping forceps with a force measuring function are reused, first remove the orthodontic force measuring accessory, and then perform disinfection and sterilization operations on the orthodontic clamping forceps.

[0020] Based on the above technical solution, when the orthodontic clamping forceps with a force measuring function are in use, first, use the jaws of the orthodontic clamping forceps to clamp the force applying device, and lock the toothed structure of the handle part of the clamping forceps; then, the thumb and index finger of the operator's single hand respectively pinch the finger pinch plates above and below the sliding member, and drive the orthodontic clamping forceps to move outward to the oral cavity for force application operation; finally, when the orthodontic force measuring accessory indicates that the applied force reaches the set force value, fix the force applying device to the orthodontic appliance, that is, complete the orthodontic force application operation.

[0021] Further, the force applying device includes a tension spring or an elastic loop; the orthodontic appliance includes a bracket or a traction hook.

[0022] The orthodontic clamping forceps provided by the present invention are equipped with a detachable orthodontic force measuring accessory. With the assistance of the orthodontic force measuring accessory, during the process of applying force to the force applying device by the operator, not only can the magnitude of the force value be immediately displayed, but also the target force value can be feedback and prompted, thereby helping the operator to apply force accurately and making the tooth movement more reasonable.

[0023] Compared with the prior art, the beneficial effects of the present invention are: (1) An orthodontic force measuring accessory provided by the present invention is a detachable device independent of the orthodontic clamping forceps, and it is detachably installed at the proximal handle end of one side of the orthodontic clamping forceps through a clamping part; after the orthodontic clamping forceps are used, the orthodontic force measuring accessory can be directly removed without being sterilized together with the clamping forceps, which is beneficial to extending the service life.

[0024] (2) An orthodontic force measuring accessory provided by the present invention is provided with an elastic cushion block between the outer side walls of the L-shaped clamping plate and the guide rail. By adjusting the locking member to squeeze the elastic cushion block to generate deformation, the elastic cushion block is compressed to different degrees, and then the included angle between the long axis of the force measuring accessory and the handle part of the clamping forceps is adjusted to ensure that the long axis of the force measuring accessory coincides with the force line during force application (that is, the central axis of the orthodontic clamping forceps) after installation, thereby ensuring the accuracy of force value measurement.

[0025] (3) An orthodontic force measuring attachment provided by the present invention is provided with a first scale reminder on the side wall at the scale line of the guide rail, and a second scale reminder is provided on the sliding member. During the force application process, when the specified scale (required force application value) is reached, the first scale reminder and the second scale reminder come into contact, and the second scale reminder generates relative movement with the sliding member body. This relative movement can be perceived by the operator holding the sliding member, thereby playing a reminder role. Compared with the force measuring orthodontic pliers where the operator needs to judge the force value by visual observation, the present invention allows the operator to focus more on the orthodontic operation itself, which helps to improve the efficiency and accuracy of the orthodontic operation.

[0026] (4) An orthodontic clamping pliers with a force measuring function provided by the present invention mounts the orthodontic force measuring attachment near the handle end of one side of the orthodontic clamping pliers, and makes the long axis of the orthodontic force measuring attachment collinear with the central axis of the orthodontic clamping pliers. During the operation in the oral cavity, the magnitude of the applied force can be monitored in real time. Compared with the conventional force measuring device that can only measure the force value and cannot perform oral cavity operations simultaneously, it can better help the operator control the force value of the force applying device, achieve accurate force application, so that the tooth movement is more efficient and accurate, and the success rate of treatment is improved. After use, first remove the orthodontic force measuring attachment, and then perform disinfection and sterilization operations on the orthodontic clamping pliers alone, which can avoid the aging or damage of the fine structure inside the orthodontic force measuring attachment during the sterilization process and extend the service life of the orthodontic force measuring attachment.

Detailed Embodiments

[0028] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0029] It should be noted that, without conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0030] The present invention will be further described below in conjunction with specific embodiments, but it is not a limitation of the present invention.

[0031] Embodiment 1 Please refer to Figure 1 and Figure 2 , this embodiment provides an orthodontic force measuring accessory, including: a guide rail 1, a sliding member 2 and a clamping part 3; the guide rail 1 includes a spring 11, a scale line 12 and a first scale indication member 13; wherein, scale lines 12 are respectively provided on both sides of the guide rail 1, and the specific scales indicated by the scale lines 12 correspond to the actually measured force application values of the orthodontic force measuring accessory, and the force measuring range is 50 g - 500 g.

[0032] The spring 11 is disposed inside the guide rail 1. The diameter of the spring 11 is smaller than the width inside the guide rail 1. One end of the spring 11 is fixed to the end of the guide rail 1, and the other end is connected to the sliding member 2 with a certain distance left from the starting end of the guide rail 1. The sliding member 2 moves along the guide rail 1 under an external force and compresses the spring 11. When the sliding member 2 moves to the target position, under the action of the first scale reminder 13, the second scale reminder 21 of the sliding member 2 generates relative movement with respect to the sliding member 2. The clamping portion 3 includes an L-shaped clamping plate 31. One end of the L-shaped clamping plate 31 is connected to the outer side wall of the guide rail 1, and the other end is provided with a locking member 32. An elastic cushion block 33 is provided between the L-shaped clamping plate 31 and the outer side wall of the guide rail 1. By adjusting the locking member 32 to squeeze the elastic cushion block 33 to generate deformation, the clamping angle of the clamping portion 3 relative to the base body is adjusted.

[0033] The orthodontic force measuring attachment provided in this embodiment is a detachable device independent of the orthodontic clamping pliers design. It is detachably mounted on the proximal handle end of one side of the orthodontic clamping pliers through the clamping portion 3. Since the orthodontic force measuring attachment is mounted on the proximal handle end of the orthodontic clamping pliers and is always located outside the patient's oral cavity during orthodontic operations, it has a low degree of contamination, does not contact the oral cavity, and will not cause cross-infection between patients. Therefore, after the orthodontic clamping pliers are used, this orthodontic force measuring attachment can be directly removed and disinfected and cleaned separately, without the need to perform complex sterilization treatment together with the clamping pliers, which is beneficial to extending the service life of the orthodontic force measuring attachment.

[0034] In the above orthodontic force measuring attachment, an elastic cushion block 33 is provided between the L-shaped clamping plate 31 and the outer side wall of the guide rail 1. By adjusting the locking member 32 to squeeze the elastic cushion block 33 to generate deformation, the elastic cushion block 33 shows different degrees of compression, thereby adjusting the angle between the long axis of the force measuring attachment and the handle portion of the clamping pliers, ensuring that the long axis of the force measuring attachment coincides with the force line during force application (i.e., the central axis of the orthodontic clamping pliers) after installation, and thus ensuring the accuracy of force value measurement.

[0035] In addition, considering that it is somewhat inconvenient for the operator to observe the scale with the naked eye and judge the magnitude of the force value during the orthodontic force application operation, the orthodontic force measuring attachment provided in this embodiment is provided with a first scale reminder 13 on the scale line 12 of the guide rail 1 and a second scale reminder 21 on the sliding member 2. During the orthodontic force application process, when the specified scale (i.e., the required force application value) is reached, the first scale reminder 13 and the second scale reminder 21 come into contact, and the second scale reminder 21 generates relative movement with respect to the sliding member 2 body. This relative movement can be perceived by the operator holding the sliding member 2, thereby playing a reminder role. Compared with the orthodontic force measuring pliers where the operator needs to judge the magnitude of the force value by observing with the naked eye, the orthodontic test attachment provided in this embodiment can enable the operator to focus more on the orthodontic operation itself, which helps to improve the efficiency and accuracy of the orthodontic operation.

[0036] Based on the above structural design, the orthodontic force measuring attachment provided in this embodiment can not only accurately feedback the real-time force value when the operator applies force in the oral cavity, but also effectively reduce the damage to the force measuring device during the disinfection process before the reuse of medical devices, extend its service life, which is of great significance for improving the efficiency and effect of orthodontic operations and reducing the use cost of medical devices.

[0037] Embodiment 2 On the basis of Embodiment 1, this embodiment makes an improved design on the specific structure of the guide rail 2, specifically as Figures 3 - 5 shown.

[0038] Please refer to Figure 3 , in the guide rail 1, there are multiple first scale prompting members 13, and they respectively correspond to the scales of the scale line 12; the first scale prompting member 13 includes a fixing portion 131 and a movable blocking block 132. The fixing portion 131 is fixedly installed on the side wall of the guide rail 1, and the top of the movable blocking block 132 can protrude a certain height from the fixing portion 131, and when the sliding member 2 moves to the scale where the movable blocking block 132 is located, it blocks the second scale prompting member 21 of the sliding member 2.

[0039] Figure 4 shows a connection method between the movable blocking block 132 and the fixing portion 131 of the first scale prompting member 13 in this embodiment: in the normal state, as Figure 4 (a) shown, the fixing portion 131 is sleeved on the middle part of the movable blocking block 132, and the upper end of the movable blocking block 132 is in an inverted trapezoid shape, so that the fixing portion 131 is stably stuck in the middle part to avoid falling; when it is necessary to prompt a specified scale, as Figure 4 (b) shown, the operator pushes the bottom of the movable blocking block 132 upward, so that the top of the movable blocking block 132 protrudes a certain height from the fixing portion 131, and then the second scale prompting member 21 of the sliding member 2 can be blocked. In this embodiment, a magnetic sheet made of magnetic material is provided at the bottom of the movable blocking block 132, and the fixing portion 131 is made of iron, and the two can be connected by magnetism, so as to maintain the protruding height of the top of the movable blocking block 132.

[0040] Based on the above structural design, in actual application, the orthodontic force measuring attachment provided in this embodiment can push up the first scale prompting member 13 at the scale 12 corresponding to the specified applied force value according to the different degrees of applied force in orthodontic operations, and the first scale prompting members 13 at other scales remain unchanged. As Figure 5 shown, when the sliding member 2 reaches the specified scale, the second scale prompting member 21 has a slight collision with the protruding movable blocking block 132 at the corresponding scale and moves relative to the sliding member 2 body, so as to realize timely feedback of the scale and force effect.

[0041] Embodiment 3 Based on Embodiment 2, this embodiment has made an improved design on the sliding member 2, specifically as follows Figures 6 - 8 as shown.

[0042] As Figure 6 shown, the sliding member 2 includes a small ball 22, a first finger pinching plate 23 and a second finger pinching plate 24; the first finger pinching plate 23 and the second finger pinching plate 24 are respectively located outside the tracks above and below the small ball 22, and are connected to the small ball 22 through connecting rods, and the small ball 22 is fixedly connected to the movable end of the spring 11.

[0043] As Figure 7 shown, the first finger pinching plate 23 includes a substrate 231 and a second scale reminder member 21, and the second scale reminder member 21 includes a free portion 232 provided on the side of the substrate 231, and a small spring 233 located between the free portion 232 and the substrate 231. Among them, the free portion 232 is a movable narrow plate, and is connected to the side of the substrate 231 through the small spring 233.

[0044] Based on the above structural design, during orthodontic operation, when the sliding member 2 reaches the specified scale, the free portion 232 located on the side of the substrate 231 collides slightly with the protruding movable stopper 132. The substrate 231 basically remains stationary under the finger pressure of the operator, and the free portion 232 connected to it through the small spring 233 will deflect relative to the substrate 231 with the small spring 233 as the center, specifically as Figure 8 shown. For the operator, it can be sensed that there is a bounce at the edge of the first finger pinching plate 23, and it can be clearly understood that the force application value has reached the target scale.

[0045] Embodiment 4 Based on Embodiment 3, this embodiment has made an improved design on the clamping member 3. Specifically, as Figure 1 shown, after the L-shaped clamping plate 31 extends outward a certain distance from the top of the side edge of the guide rail 1 and then extends downward at a 90° angle, it includes a first clamping plate 311 and a second clamping plate 312. The first clamping plate 311 is in the shape of a right trapezoid, its right-angle waist is connected to the second clamping plate 312, and its oblique waist is connected to the outer side wall of the guide rail 1; the locking member 32 is a pair of screws provided on the second clamping plate 312, and screw holes are provided at the positions corresponding to the screws on the second clamping plate 312.

[0046] As Figure 9As shown, in this embodiment, the elastic cushion block 33 is a prismatic rubber block with right trapezoidal upper and lower bases; in the rubber block, the side surface connected to the oblique waists of the upper and lower bases of the right trapezoid is fixed to the outer side wall of the guide rail 1; the rubber block, the first clamping plate 311 and the second clamping plate 312 enclose a U-shaped clamping space. Further, in order to improve the clamping firmness, in the U-shaped clamping space, the inner walls of the L-shaped clamping plate 31 and the rubber block are both provided with rough surfaces to increase the friction during the clamping process and prevent the orthodontic force measuring accessory from moving relative to the clamping base during use.

[0047] Based on the above structural design, during the installation of the orthodontic force measuring accessory, first, the L-shaped clamping plate 31 is clamped at the near handle end of one side of the orthodontic clamping forceps, and the clamping arm is located in the U-shaped clamping space enclosed by the rubber block, the first clamping plate 311 and the second clamping plate 312. By tightening the locking member 32, the orthodontic force measuring accessory is stably installed on the orthodontic clamping forceps, making the two form an integral structure in terms of structure, which is convenient for the operator to hold the orthodontic force measuring accessory later to drive the orthodontic clamping forceps to apply force.

[0048] Further, in order to accurately feedback the force application situation, it is necessary to ensure that the long axis of the orthodontic force measuring accessory is collinear with the central axis of the clamping forceps. The clamping member 3 of the orthodontic force measuring accessory provided in this embodiment is provided with an elastic rubber block. After the orthodontic test accessory is installed, the locking member 2 on one side can be further tightened or loosened to finely adjust the installation angle of the orthodontic force measuring accessory to ensure that it is collinear with the axis of the clamping forceps and ensure the accuracy of the force value measurement.

[0049] Embodiment 5 As Figure 10 shown, this embodiment provides an orthodontic clamping forceps with a force measuring function, including an orthodontic clamping forceps 4 and the orthodontic force measuring accessory provided in Embodiment 4; the orthodontic force measuring accessory is installed at the near handle 42 end of one side of the orthodontic clamping forceps 4, and the long axis of the orthodontic force measuring accessory is collinear with the central axis of the orthodontic clamping forceps 4.

[0050] Taking the orthodontic operation of a single molar as an example, this embodiment demonstrates the usage method of the above-mentioned orthodontic clamping forceps with a force measuring function, which specifically includes the following steps: Step 1: According to the required force value of 200 g for the orthodontic operation of a single molar, push the movable block 132 of the first scale reminder 13 corresponding to the 200 g scale line 12 upward; Step 2: Buckle the clamping part 3 of the orthodontic force measuring accessory to the near handle 42 end of one side of the orthodontic clamping forceps 4, and turn the locking member 32 of the clamping part 3 to stably fix the orthodontic force measuring accessory on the orthodontic clamping forceps 4 to form an integral structure in terms of structure; Step 3: Determine the angle between the long axis of the orthodontic force measuring attachment and the axis of the orthodontic holding forceps 4. Adjust the tightness of the first screw 321 and the second screw 322 of the locking member 32 to change the angle between the guide rail 1 and the orthodontic holding forceps 4, so that the long axis of the orthodontic force measuring attachment is on the same straight line as the axis of the orthodontic holding forceps 4; Step 4: Use the jaws 43 of the orthodontic holding forceps 4 to grip the force applying device that needs to be stretched. Under the fixation of the toothed structure 44 that engages with each other at the bottom of the handle 42 of the orthodontic holding forceps 4, the orthodontic holding forceps 4 are always in the engaged state; Step 5: The operator pinches the first finger pinching plate 23 and the second finger pinching plate 24 of the sliding member 2 of the orthodontic force measuring attachment with the thumb and index finger of one hand, and exerts force backward (towards the outside of the oral cavity). Since the orthodontic force measuring attachment is installed on the orthodontic holding forceps 4 and the two form a structural whole, the pulling force exerted by the operator on the sliding member 2 backward drives the orthodontic holding forceps 4 to move backward, thereby stretching the force applying device. On the other hand, the spring 11 in the guide rail 1 is compressed. As the force applying device is gradually stretched, the spring 11 is further compressed, causing the sliding member 2 to move backward relative to the force measuring attachment base; Step 6: When the sliding member 2 moves to the position where the pushed movable stop block 132 is located, under the action of the movable stop block 132, the free portion 232 at the edge of the first finger pinching plate 23 will rotate, and the operator is prompted by touch that the set force value has been reached at this time; Step 7: Fix the force applying device to the orthodontic appliance, that is, complete the force application operation of 200 g for a single molar.

[0051] Further, in the above usage method, the force applying device is a tension spring or an elastic ring; the orthodontic appliance is a bracket or a traction hook.

[0052] Further, before the orthodontic holding forceps with force measuring function are reused, first remove the orthodontic force measuring attachment, and then perform disinfection and sterilization operations on the orthodontic holding forceps 4.

[0053] Compared with the existing orthodontic holding forceps with force measuring function, the orthodontic holding forceps with force measuring function provided in this embodiment use a detachable force measuring attachment independent of the orthodontic holding forceps body. This detachable way of the force measuring attachment not only reduces the damage to the fine parts inside the force measuring attachment caused by frequent sterilization and disinfection, and extends the service life of the force measuring attachment; moreover, when a certain orthodontic operation does not involve force application, the force measuring attachment can not be used. The volume and weight of the holder without the force measuring attachment are relatively small, which is convenient for holding and operation. When force application is required, the force measuring attachment can be installed in advance and operated.
