Description

Technical Field

[0001] The invention belongs to the technical field of oral medical instruments, and in particular relates to an auxiliary instrument for tooth extraction in the oral department. Background Art

[0002] Stomatology was originally part of the ENT department, but with the continuous refinement of medical specialties and the advancement of the reform of the Ministry of Health, it has now developed into an independent specialist department. The general classification of stomatology is mainly based on oral diseases, teeth and dental lesions, and is further subdivided into oral beauty, dental implants, orthodontics, oral ulcer treatment, oral inflammation treatment and other professional fields.

[0003] Surgical tooth extraction is a basic and commonly used treatment method in dentistry, which aims to treat certain systemic or local diseases by removing diseased teeth. When performing dental treatment, dentists will use a variety of professional tools. Among them, in addition to the most critical tooth extraction forceps, dental elevators, as a tooth extraction auxiliary instrument, are also very important. The dental elevator consists of three parts: the beak, the lever and the handle. Its main function is to break the periodontal membrane and loosen the tooth root, thereby facilitating the tooth extraction operation. During the tooth extraction process, the beak of the dental elevator is inserted into the gap between the tooth root and the alveolar bone, and the alveolar ridge is used as a prying fulcrum. Through the rotational action and the wedge-shaped force applied to the root apex, the periodontal membrane fibers can be broken, and the tooth to be extracted can be gradually loosened, thereby facilitating the subsequent extraction operation. However, there are certain risks in this process. If the doctor does not control the force accurately enough during the operation, or the direction of the force is deviated, it may cause unnecessary damage to the alveolar ridge, which may cause congestion and edema of local tissues, and even induce inflammatory reactions, which will have an adverse effect on the patient's daily life and eating habits, and require a certain amount of time to recover. What's more serious is that this damage may also cause the height of the alveolar ridge to decrease and the width to narrow, which in turn affects its ability to withstand the force of the teeth and support the denture. On the other hand, if the alveolar ridge is not used as a prying fulcrum, the dental bridge will lack the necessary support structure during use, resulting in inconvenience in exerting force, thereby reducing the efficiency of tooth extraction.

[0004] Therefore, we propose a dental tooth extraction auxiliary instrument to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 5 The present invention provides an auxiliary dental extraction device for oral medicine, comprising a supporting brace and a dental elevator assembly, the supporting brace comprising a brace hoop 1 and a brace block 2, the brace hoop 1 being a U-shaped structure, a notch 3 being provided on the side away from the brace hoop 1 and the brace block 2, an extended support assembly with adjustable height being provided above the brace block 2, the extended support assembly being slidably connected to the bottom of the brace hoop 1, the dental elevator assembly comprising a telescopic adjustment cylinder 4, a connecting seat 5 and a dental elevator body, the telescopic adjustment cylinder 4 being slidably connected to the bottom of the brace hoop 1, the connecting seat 5 being rotatably sleeved on the telescopic end of the telescopic adjustment cylinder 4, the dental elevator body comprising a dental elevator head 6 and a dental elevator rod 7, the dental elevator head 6 being hinged on the connecting seat 5, the lower end of the dental elevator rod 7 being detachably connected to the upper end of the dental elevator head 6, the dental elevator rod 7 being bent to extend out of the oral cavity, and a handle 8 being provided at the end.

[0032] In this embodiment, the support brace can stably and effectively open the patient's mouth during the treatment process, thereby avoiding the defensive reaction caused by the discomfort caused by tooth extraction, and ensuring the smooth progress of the treatment process. In actual operation, according to the position of the patient's teeth to be extracted, the wearing method of the support brace is flexibly adjusted. When the teeth to be extracted are located on the lower side of the mouth, the brace band 1 is worn on the top and the brace block 2 is worn on the bottom. On the contrary, when the teeth to be extracted are located on the upper side of the mouth, the brace band 1 is worn on the bottom and the brace block 2 is worn on the top. By sliding the extended support component flexibly under the brace band 1, the brace block 2 is slid to the side away from the teeth to be extracted, so as to keep the space at the teeth to be extracted open, so as to adapt to the extraction needs of different positions. The extended support component not only has the function of adjusting the distance between the brace band 1 and the brace block 2, but also can keep the patient's mouth open, broaden the dentist's field of vision, and facilitate the dentist to perform tooth extraction. When wearing the brace, it should be ensured that the patient's teeth can bite into the notch 3, so as to provide a stable and reliable support basis for the tooth extraction process. In the process of loosening teeth, firstly rotate the dental lifter head 6 to the inner or outer side of the tooth to be pried through the connecting seat 5, so that the prying surface of the dental lifter head 6 faces the tooth, and then install the dental lifter rod 7 on the upper end of the dental lifter head 6, and then accurately position the dental lifter head 6 above the tooth to be extracted by sliding the telescopic adjustment tube 4 under the dental brace 1. The telescopic adjustment tube 4 can adjust the height of the connecting seat 5 and the dental lifter body. The connecting seat 5 can be rotatably mounted on the telescopic end of the telescopic adjustment tube 4, allowing the dental lifter body to rotate on the horizontal plane. Through the coordination of the height adjustment of the telescopic adjustment tube 4 and the angle adjustment of the connecting seat 5, the dental lifter head 6 can be inserted into the gap between the tooth root and the alveolar bone at different angles to meet the needs of tooth extraction at different angles. When the dental lifter head 6 is inserted into the gap between the tooth root and the alveolar bone, the dental lifter rod 7 can be easily rotated by the handle 8 or the connecting seat 5 can be controlled to rotate, so that the dental lifter head 6 can be effectively controlled to pry the tooth to be extracted, causing the periodontal membrane fibers to break and gradually loosening the tooth to be extracted, thereby facilitating the subsequent extraction operation. It is worth mentioning that the hinged design between the dental lifter head 6 and the connecting seat 5 uses the connecting seat 5 as a prying fulcrum during the process of the dental lifter head 6 loosening the tooth to be extracted, which not only effectively reduces the damage that may be caused to the alveolar ridge during the traditional tooth extraction process, but also improves the force effect, making the tooth extraction process more efficient, stable and flexible. This design undoubtedly provides a powerful auxiliary instrument for dentists and significantly improves the safety of tooth extraction treatment.

[0033] In a specific embodiment, see Figure 1 and Figure 4The extended support assembly includes a bracket and a lead screw 9, the lower end of the bracket is connected to the braces block 2, the upper end of the bracket is slidably connected to the braces hoop 1, the bracket is a scissor-type bracket with four arms symmetrical up and down, and the upper and lower arms are connected by a hinge shaft 10. The lead screw 9 vertically penetrates the two hinge shafts 10 and is rotatably connected to the inner hinge shaft 10 and is threadedly connected to the outer hinge shaft 10.

[0034] The extended support assembly includes two parts, a bracket and a lead screw 9. The bracket adopts a symmetrical scissor-type structure design composed of four arms, which has strong stability and can ensure that the patient's mouth can be effectively and firmly opened, providing a wide operating field for dentists. The upper and lower arms are connected by a hinge shaft 10, so that the upper and lower arms of the bracket can rotate. The lead screw 9 passes through the inner and outer hinge shafts 10 respectively, and at the inner hinge shaft 10, the lead screw 9 adopts a rotatable connection method to ensure the smooth rotation action, while at the outer hinge shaft 10, the lead screw 9 adopts a threaded connection method. This design enables the two hinge shafts 10 to move closer or farther from each other when the lead screw 9 rotates, thereby realizing the deformation of the scissor-type bracket, and then adjusting the distance between the brace hoop 1 and the brace block 2. The dentist can quickly adjust the degree of oral opening through a simple rotation action, thereby greatly improving the efficiency of the tooth extraction operation.

[0035] In a specific embodiment, see Figure 4 The bracket includes a first support seat 11, a second support seat 12, two first support arms 13 and two second support arms 14. The first support seat 11 is fixedly connected to the top surface of the braces block 2, and the second support seat 12 is slidably connected to the bottom of the braces hoop 1. The ends of the first support arm 13 and the second support arm 14 are connected by a hinge shaft 10. The two first support arms 13 are symmetrically hinged on the first support seat 11, and the two second support arms 14 are symmetrically hinged on the second support seat 12.

[0036] The first support base 11, the second support base 12, the two first support arms 13, the two second support arms 14 and the two hinge shafts 10 together constitute a stable support system, which ensures the stability of the bracket when opening the oral cavity and further improves its reliability and safety during use.

[0037] In a specific embodiment, see Figure 4 An adjusting ring 15 is provided at the outer end of the lead screw 9 .

[0038] The design of the adjustment ring 15 allows the dentist to insert other rods into the adjustment ring 15 when rotating the lead screw 9, thereby more conveniently adjusting the distance between the dental brace hoop 1 and the dental brace block 2.

[0039] In a specific embodiment, see Figure 2 and Figure 3 The telescopic adjustment cylinder 4 includes a sleeve 401 and a telescopic rod 402. The upper end of the sleeve 401 is slidably connected to the brace hoop 1. The telescopic rod 402 is slidably installed in the sleeve 401. The connecting seat 5 is rotatably sleeved on the telescopic rod 402.

[0040] By sliding the telescopic rod 402 in the sleeve 401, the height of the connecting seat 5 can be easily adjusted, driving the height of the dental lifter head 6 to be adjusted, so that the dental lifter head 6 can be inserted into the gap between the tooth root and the alveolar bone more flexibly, which is conducive to improving the efficiency of tooth extraction.

[0041] In a specific embodiment, see Figure 1-Figure 5 A U-shaped T-shaped slide rail 16 is provided below the dental brace 1, and both ends of the T-shaped slide rail 16 extend to the two end surfaces of the dental brace 1, and the top surfaces of the extended support assembly and the telescopic adjustment cylinder 4 are provided with sliders 17 that cooperate with the T-shaped slide rail 16.

[0042] The T-shaped slide rail 16 is designed to be U-shaped. When the slider 17 slides along the T-shaped slide rail 16, it can slide well with the dental brace 1 and can accurately match the position of the teeth. In addition, the two ends of the T-shaped slide rail 16 extend to the two end surfaces of the dental brace 1, which not only allows the extended support assembly and the telescopic adjustment cylinder 4 to slide out of the dental brace 1, but also provides great convenience for subsequent disinfection and cleaning. It is worth mentioning that this detachable connection design provides a wide range of choices for dental elevators of different specifications and shapes. Dentists can easily replace suitable dental elevators according to different tooth extraction needs, thereby significantly improving the adaptability and flexibility of tooth extraction operations, and providing patients with a more personalized and efficient tooth extraction solution.

[0043] In a specific embodiment, see Figure 2 and Figure 3 The lower end of the dental lifter head 6 is arc-shaped.

[0044] The dental lifter head 6 adopts an arc-shaped design, which can better observe the structure of the teeth, the shape of the roots, and the relationship between the teeth and surrounding tissues when prying the teeth, so that the prying point and force can be judged more accurately, and it can also increase the operating space at the tooth to be extracted, reduce the impact on the subsequent tooth extraction operation of the extraction forceps, and further improve the accuracy and safety of the tooth extraction operation.

[0045] In a specific embodiment, see Figure 2 A support rod 18 is provided on one side of the connecting seat 5 , and the dental lifter head 6 is movably sleeved on the support rod 18 .

[0046] In the process of prying the tooth to be extracted, the dental lifter head 6 uses the support rod 18 on the connecting seat 5 as a stable fulcrum, thereby optimizing the force effect, making the tooth extraction process not only more efficient and stable, but also significantly reducing the potential damage to the alveolar ridge. In addition, the dental lifter head 6 is movably sleeved on the support rod 18, so that the dental lifter head 6 can be easily removed from the support rod 18, which not only facilitates the dentist to replace the dental lifter head 6 of different specifications or shapes when needed, but also facilitates the cleaning and maintenance of the dental lifter head 6, effectively extending the service life of the entire set of equipment.

[0047] In a specific embodiment, see Figure 2 The outer side of the support rod 18 is threadedly connected to a limiting block 19 .

[0048] By threading the limit block 19 on the outer side of the support rod 18, this design can effectively prevent the dental elevator head 6 from slipping due to careless operation during the process of prying the tooth to be extracted, thereby improving the safety of the tooth extraction operation.

[0049] In a specific embodiment, see Figure 2 and Figure 3 The lower end of the dental lifter 7 is provided with a cartridge 20 , and the cartridge 20 is clamped and connected to the upper end of the dental lifter head 6 .

[0050] The dental lifter 7 is clamped and connected to the upper end of the dental lifter head 6 through the clamping cylinder 20, which can not only realize the detachable connection design between the dental lifter 7 and the dental lifter head 6, but also ensure the stability of the connection between the two. Before tooth extraction, no matter the dental lifter head 6 is on the inside or outside of the tooth to be extracted, the dental lifter 7 can be extended outside the oral cavity after installation, which is very important to ensure the smooth progress of the tooth extraction operation.

[0051] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
