Description

Tooth extraction device

Technical Field

The invention relates to a tooth extraction device, in particular to a tooth extraction device which has a simple structure, is convenient to operate, reduces damage and injury of peripheral tissues during tooth extraction by using a minimally invasive mode, can reduce tools and saves tooth extraction force.

Background

Dental extraction refers in dentistry to the removal of teeth from the oral cavity, usually by local anesthesia of the oral cavity before surgery. A common tooth extraction method is a forceps extraction method, which is performed with sufficient crown portions remaining: the dental forceps are used for fixing the dental crown to shake and turn, the combination of the tooth root and the alveolar bone is damaged, then the tooth is pulled and pulled out, for the tooth with difficult position, the tooth can be pulled out by methods of pulling out a dental elevator, pushing the dental elevator, wedging and the like, or the tooth to be pulled out is cut into a plurality of parts to be respectively pulled out, for the tooth hidden under the dental pulp and with poor germination, or the residual tooth root, the dental pulp is separated in an operation mode, even the bone is ground, and the tooth is pulled out by the tooth pulling instrument after being exposed. The tooth extraction process uses quite complicated instruments, and the sound or pain generated by most operation means can cause panic of patients, so that most patients still have fear to tooth extraction to a certain extent in the modern developed medical technology.

The tooth extraction instrument, such as "method and device for extracting tooth root" in Chinese patent CN1735386A, is mainly fixed in the tooth root by means of nails (such as root canal screws), and the tension device (such as a steel cable) is activated to pull and extract along the axial direction of the tooth root in an electric or rotary manner. Although it is stated that the root of the tooth can be put into greater traction with a simple operation without requiring the user to expend a great deal of effort and without space problems, the risk of injury in the mouth is also reduced. However, the manufacturing cost or the actual selling price is not good for the user, and the utility is too narrow to remove the stump, so the CP value is too low, and the force of shaking the knob can be saved, but the fixing device body still needs to be held by force to avoid being pulled back by the tension device.

However, the above-mentioned tooth extraction device has the following problems and disadvantages to be improved when used:

first, the manufacturing cost or the actual selling price is too high, and the popularization rate of the dental implant is inhibited.

Secondly, the operation purpose or the application condition is not wide enough.

Thirdly, the force of resisting the tension device needs to be consumed, and the tension device is not easy in nature.

How to solve the above-mentioned problems and deficiencies is a direction in which the authors of the present invention and the related manufacturers engaged in the industry need to research and improve.

Disclosure of Invention

In view of the above-mentioned shortcomings, the inventor of the present invention has searched relevant data, and has designed a tooth extraction device with simple structure, convenient operation, less damage to peripheral tissues during tooth extraction, less tools and less tooth extraction force by continuous trial and modification based on years of experience accumulated in the industry.

The main purposes of the invention are as follows: the operation mode is simplified, and the device is suitable for common tooth extraction, residual root extraction and other purposes through a single clamping assembly.

In order to achieve the purpose, the invention adopts the technical scheme that: a tooth extraction device comprising: the clamping assembly comprises a first clamping arm and a second clamping arm pivoted on the first clamping arm, a prying assembly is formed at one end of the first clamping arm and comprises a linkage arm formed at one end of the first clamping arm and a supporting hook formed at one end of the linkage arm, the linkage arm and the supporting hook are matched with a tooth fixing piece to move so as to remove a first tooth, two first buffer pieces are defined at one end of the second clamping arm and are supported on a plurality of second teeth to serve as force application supporting points of the prying assembly, a first spacing part is formed among the first buffer pieces so that the prying assembly can move in the first spacing part, and a second buffer piece is defined at one end of the second clamping arm and is supported on the second teeth to serve as force application supporting points of the prying assembly.

When the tooth pulling device is used for pulling out teeth, a user firstly locks or clamps a tooth fixing piece on a first tooth, then, according to the distribution condition of a second tooth, the first buffer piece or the second buffer piece is abutted against the second tooth, the abutting hook part is abutted against or clamped at one side of the tooth fixing piece, finally, the user slowly applies force to the clamping assembly, so that the first clamp arm and the second clamp arm swing mutually, and the linkage arm drives the abutting hook part to be upwards lifted, so that the first tooth is pulled out easily and laborsavingly by using the least tools.

After the technology is adopted, the problems of overhigh cost, narrow use, laborious operation and low popularization rate of the existing tooth extraction instrument can be overcome, and the practical progress of the advantages is achieved.

Detailed Description

To achieve the above objects and advantages, the present invention provides a technical means and a structure, which will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, it can be clearly seen that the present invention includes:

a clamping assembly 1, wherein the clamping assembly 1 comprises a first clamping arm 11 and a second clamping arm 12 pivoted on the first clamping arm 11;

a recess 121 formed in the second jawarm 12 for receiving the mouth corner;

a prying component 2 formed at one end of the first clamp arm 11, wherein the prying component 2 comprises a linkage arm 21 formed at one end of the first clamp arm 11 and a supporting hook 22 formed at one end of the linkage arm 21, and the linkage arm and the supporting hook cooperate with a tooth fixing piece 5 to remove a first tooth;

two first buffer parts 3 defined at one end of the second tong arm 12, which are abutted against a plurality of second teeth to be used as force application pivots of the prying component 2;

a first spacing portion 32 formed between the first buffers 3, and the prying assembly 2 is movable in the first spacing portion 32; and

a second buffer member 4 defined at one end of the second forceps arm 12 and located at one side of the first spacing portion 32, abuts against the second tooth to serve as a force application fulcrum of the levering assembly 2.

The tooth fixing member 5 includes a tooth drilling portion 51, a clamping head 52 disposed at one end of the tooth drilling portion 51, and a positioning portion 53 formed on an end surface of the clamping head 52 facing away from the tooth drilling portion 51.

Through the above description, the structure of the present technology can be understood, and according to the corresponding cooperation of the structure, the present technology has the advantages of simple structure, low manufacturing cost, convenient operation, and using a minimally invasive method to reduce the damage of the surrounding tissues during tooth extraction, and also achieving the advantages of reducing the use of tools, saving tooth extraction force, etc., and the detailed description will be described below.

Referring to fig. 1 to 10, when the above-mentioned components are used, it can be clearly seen from the drawings that in the present embodiment, the first forceps arm 11 and the prying element 2 are integrally formed, and the second forceps arm 12, the first buffer 3 and the second buffer 4 are integrally formed, and the first forceps arm 11 and the second forceps arm 12 are pivoted to each other, so that the clamping element 1 can pry up the first tooth 61 (i.e. the affected tooth) by using the principle of leverage.

In practical use, a tooth fixing member 5 is first locked on the first tooth 61, and the first tooth 61 of the present embodiment uses the tooth stump as an example, so the tooth fixing member 5 is formed by modifying a root canal screw, the existing tooth drilling portion 51 is reserved, a clamping head 52 is specially manufactured for the prying component 2 to support, and a positioning portion 53 is designed on the top surface of the clamping head 52 to fix the dental floss 531 in a penetrating or winding manner, so as to avoid the risk of splashing when the first tooth 61 is pulled out. Therefore, when the tooth fixture 5 is locked to the first tooth 61, the bit 51 is inserted along the neural canal, and the clamping head 52 is exposed (see fig. 4). Next, the clamping assembly 1 is placed in the mouth of the patient, and the mouth corner 63 is partially received in the recess 121 by the design of the recess 121, thereby reducing the extent to which the cheek is spread by the clamping assembly 1 and reducing the discomfort of the patient (as shown in fig. 5). Then, according to the distribution of the second teeth 62 (i.e. other teeth), the first buffer member 3 or the second buffer member 4 is abutted against the second teeth 62, as shown in fig. 6, for the user, the first buffer members 3 located at both sides of the prying assembly 2 are utilized to abut against the second teeth 62 at both left and right sides of the first teeth 61, and the abutting hook portion 22 is abutted against the lower portion of the clamping head 52, and the bottom of the clamping head 52 is designed to be arc-shaped (or designed to be in a state of small diameter), which is not only beneficial to positioning of the abutting hook portion 22, but also avoids abutting against the adjacent second teeth 62. Finally, as shown in fig. 7, the user applies a force to the clamping assembly 1 slowly, and the first buffer member 3 is used as a fulcrum of the force application, so that the first clamping arm 11 and the second clamping arm 12 swing with each other, and the linking arm 21 drives the abutting hook 22 to tilt upwards, so as to easily and laborsavingly remove the first tooth 61 with a minimum number of tools. The connecting arm 21 is connected to the first forceps arm 11, and has a thick structure and a high structural strength, so as to support the external force required by the tooth extraction, and the portion of the connecting arm 21 close to the supporting hook 22 is designed to be slightly smaller than the width of the teeth, so that the connecting arm 21 forms a tapered shape.

In addition, as shown in fig. 8, if the distribution of the second teeth 62 or the position of the first teeth 61 is not favorable for the first cushion member 3 to abut, the second cushion member 4 can abut. For example, when the first tooth 61 is a wisdom tooth (the innermost tooth), since only one side of the first tooth 61 has the second tooth 62, the two first cushion members 3 cannot be abutted against the second teeth 62 on the left and right sides, so the second cushion member 4 is abutted against a single second tooth 62, and the purpose of facilitating the force application can be achieved.

As shown in fig. 9, for the sake of sanitary safety, the second caliper arm 12 may have a plurality of first buffer abutting portions 122 (in the embodiment, rod-shaped), and each of the first buffer 3 and the second buffer 4 may have a second buffer abutting portion 31, 41 (in the embodiment, through-hole-shaped) correspondingly coupled to each of the first buffer abutting portions 122. Therefore, the first buffer member 3 and the second buffer member 4 can be directly drawn out to replace new products after each use, thereby avoiding the actions of disinfection and sterilization.

As shown in fig. 10, during the operation of the clamping assembly 1, the pressing action of the first clamping arm 11 and the second clamping arm 12 is generally a slow pressing action, even a partial pulling action is required to reduce the pain of the patient and avoid hurting the portion other than the first tooth 61, so as to increase the convenience of the use of the clamping assembly 1, an elastic component 13 connecting the first clamping arm 11 and the second clamping arm 12 can be provided on the clamping assembly 1, so that when the user releases the pressing action of the first clamping arm 11 and the second clamping arm 12, the elastic component can be automatically ejected and restored. In the embodiment, the elastic component 13 is illustrated as a spring sheet.

As shown in fig. 11 to 13, it is clear that the present embodiment is similar to the above embodiments, and only the clamping head 52a of the tooth fixing member 5a has a plurality of clamping hook portions 521a arranged side by side, and the tooth fixing member 5a has a long nail as shown in fig. 11, and the tooth fixing member 5a also has a tooth drilling portion 51a, a clamping head 52a and a positioning portion 53a, and the shape is suitable for removing the horizontal wisdom teeth (the first teeth 61 a). In practical use, the crown of the first tooth 61a is cut off to make the space between the first tooth 61a and the adjacent second tooth 62a free, and then the drilling portion 51a is locked into the first tooth 61a, and then, during tooth extraction, the patient is guided to open the mouth to allow the physician to respectively abut the first cushion member 3 against the upper and lower rows of the second teeth 62a, thereby increasing the positioning effect and supporting strength of the first cushion member 3, so that the abutting hook 22a is placed at the hook 521a at a proper position by using the first cushion member 3a as a force application fulcrum, and the first tooth 61a can be extracted by using the clamping assembly 1a according to the same operation principle.

As shown in fig. 14 and 15, it is clear that the embodiment is the same as the above embodiment, and only the second buffer 4b has an extending portion 421b and two buffering portions 422b respectively disposed on opposite sides of the extending portion 421b, and a second spacing portion 423b having a width greater than that of the first spacing portion 32b is formed between the two buffering portions 422 b. Based on the design of the first buffer abutting portion 122b, the second buffer 4b can be replaced with the appearance of the present embodiment, wherein the buffer portions 422b are disposed on different sides of the arm extending portion 421b, so the distance between the two buffer portions 422b is equal to the size of the second spacing portion 423b, and the width of the second spacing portion 423b is greater than the width of the first spacing portion 32b, so that the two buffer portions 422b are located outside the first buffer 3b, in other words, if the second tooth 62b at the adjacent position of the first tooth 61b is absent or incomplete, the second buffer 4b of the present embodiment can be used to bridge the second tooth 62b, which is far from the first tooth 61b, with the buffer portions 422b (or simultaneously with the first buffer 3b), thereby increasing the applicability of the present invention.

As shown in fig. 16, it can be clearly seen that, the present embodiment is the same as the above embodiments, and only one end of the first caliper arm 11c and the second caliper arm 12c away from the prying assembly 2c is respectively provided with a first force arm butt-joint portion 14c, and each first force arm butt-joint portion 14c is respectively provided with a force arm extension member 15c, and each force arm extension member 15c is respectively provided with a second force arm butt-joint portion 151c correspondingly combined with each first force arm butt-joint portion 14c, wherein the first force arm butt-joint portion 14c and the second force arm butt-joint portion 151c are butt-jointed and fixed in a screwing and locking manner. The user can add the arm of force extension piece 15c at the rear end of the first tong arm 11c and the second tong arm 12c to lengthen the moment length of the lever principle, thereby reducing the external force requirement applied by the user to the first tong arm 11c and the second tong arm 12c and achieving the purpose of saving labor.

Referring to fig. 17 and 18, it is clearly seen that the present embodiment is the same as the above embodiment, only one end of the first caliper arm 11d and the second caliper arm 12d away from the prying assembly 2d is respectively provided with a first force arm butt-joint portion 14d, each first force arm butt-joint portion 14d is provided with a pressing assembly 16d, the pressing assembly 16d is provided with a plurality of third force arm butt-joint portions 161d correspondingly combined with each first force arm butt-joint portion 14d, the pressing assembly 16d is provided with a screw rod portion 162d and an operating portion 163d for rotating the screw rod portion 162d, and each third force arm butt-joint portion 161d is movably disposed on the screw rod portion 162d, wherein the first force arm butt-joint portion 14d and the third force arm butt-joint portion 161d are butt-fixed in a screwing manner, so as to drive the screw rod portion 162d to rotate by rotating the operating portion 163d, the operation portion 163d of the present embodiment is composed of a connecting rod 1631d and a rotating wheel 1632d pivotally disposed on the connecting rod 1631d, so that the user can grasp the rotating wheel 1632d by the fingertip with a fixed gesture to control the swinging of the connecting rod 1631 d. At this time, since the third force arm abutting portion 161d is fixedly disposed at the rear ends of the first and

second clamp arms

11d and 12d, the rotation of the screw portion 162d will cause the third force arm abutting portion 161d to retract (in this embodiment, the third force arm abutting portion 161d at the rear end of the first clamp arm 11d is fixed, and the third force arm abutting portion 161d at the rear end of the second clamp arm 12d is driven upward).

Referring to fig. 19 to 21, it is clear that the present embodiment is similar to the above embodiments, and is only an example of another structure of the tooth fixing member 5 e. The tooth fixing member 5e comprises a first clamping arm 54e, a second clamping arm 55e pivotally disposed on the first clamping arm 54e, a first clamping portion 541e formed at one end of the first clamping arm 54e, a second clamping portion 551e formed at one end of the second clamping arm 55e, at least one through hole 56e formed at one side of the first clamping arm 54e and the second clamping arm 55e and cooperating with the abutting hook portion 22e, and a pressing member 57e disposed on the first clamping arm 54e and the second clamping arm 55e, and the tooth fixing member 5e is configured to fix the side of the crown of the first tooth 61e according to the above-mentioned structure by using the clamping principle.

In practical use, the first clamping arm 54e and the second clamping arm 55e are placed on two sides of the first tooth 61e, and the tightness of the pressing member 57e is adjusted, so that the second clamping arm 55e pivoted on one side of the first clamping arm 54e is inwardly contracted through the design of the screw, so that the first clamping portion 541e and the second clamping portion 551e jointly encircle the side surface of the first tooth 61e, and in this embodiment, the first clamping portion 541e and the second clamping portion 551e are arc-shaped, so as to be favorably attached to the side surface of the first tooth 61e in a floating manner. After the pressing operation is completed, the holding hook 22e is inserted into the through hole 56e, and the clamping assembly 1e is used to pull up the first tooth 61 e. The through hole 56e can be a hole formed by a square frame shown in the figure, or a hollow space between the pressing member 57e, the first clamping arm 54e and the second clamping arm 55e, and the opening directions of the square frame and the hollow space are perpendicular to each other, which is beneficial for a user to support from different directions, thereby increasing the convenience of operation.

Referring to fig. 22 to 24, it is clear that the present embodiment is similar to the above embodiments, and is only an example of another structure of the tooth fixing member 5 f. The tooth fixing member 5f has a holding portion 58f on a side of the first clamping arm 54f and the second clamping arm 55f away from the first clamping portion 541f and the second clamping portion 551f, respectively, a first limiting portion 542f is disposed on the first clamping arm 54f, and a second limiting portion 552f correspondingly coupled to the first limiting portion 542f is disposed on the second clamping arm 55f, so as to prevent the first clamping arm 54f and the second clamping arm 55f from shifting up and down. In this embodiment, the tooth fixing member 5f is also used to fix the side of the crown of the first tooth 61f by using the clamping principle, but since the tooth fixing member 5f is in the shape of a scissors, the first clamping arm 54f and the second clamping arm 55f can be driven by operating the holding portion 58f, so as to avoid the problem of vertical deviation caused by the long length of the first clamping arm 54f and the second clamping arm 55f, the inner sides of the first clamping arm 54f and the second clamping arm 55f are respectively provided with a first limiting portion 542f and a second limiting portion 552f which are respectively in the shape of a convex rib and a concave groove, so that the first clamping arm 54f and the second clamping arm 55f can be engaged with each other in a concave-convex manner when being abutted against each other, thereby achieving the effect of preventing vertical deviation, and after clamping, the tooth fixing member 57f can also be used to fix the tooth fixing member. Thus, by using the clamping assembly 1f and the scissors-type tooth fixing member 5f, the first buffer member 3f can be used as a fulcrum and force can be applied through the through hole 56f of the supporting hook 22f, so that the user can conveniently surround the first holding portion 541f and the second holding portion 551f outside the first tooth 61 f.

As shown in fig. 25, it is clear that the embodiment is the same as the above embodiments, and has an extending clamping portion 59g on one side of the first clamping portion 541g and the second clamping portion 551 g. In this way, even if the first tooth 61g is a stump, the first clamping portion 541g and the second clamping portion 551g cannot directly surround the lateral surface of the crown, the extending clamping portion 59g can still be inserted into the stump under the tooth pulp, and the clamping principle is also utilized to fix the first tooth 61g, but the clamping force is limited, and the first tooth 61g is generally suitable for the first tooth 61g with a single root or double roots.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, so that the present invention is not limited to the above description and the accompanying drawings.
