Description

Technical Field

[0001] The present invention relates to the technical field of oral instruments, and specifically, to an adjustable point-support oral angle retractor device. Background Art

[0002] In oral surgery, it is inevitable to retract the oral angle. Generally, an oral angle retractor hook is used to ensure sufficient exposure of the surgical field, which is crucial for the successful completion of the surgery. Due to the limited operating space in the oral cavity, doctors often need to manually retract the oral angle with the assistance of instruments to expose the operating space and prevent accidental scratching of soft tissues. However, on the one hand, this operation forces doctors to hold instruments with one hand to complete some delicate operations, resulting in an extended operation time and increased operation difficulty. On the other hand, if an assistant provides retraction assistance to expose the surgical field, it will increase the risk of surgical area contamination and cause obstruction of the surgical field view. These greatly limit the flexibility and precision of doctors' operations; moreover, retracting in this way will cause the patient's oral angle to become red and swollen or even ulcerated, seriously affecting the patient's medical experience. Therefore, there is an urgent need for a new oral angle retractor device to solve the above problems. Summary of the Invention

[0031] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0032] As Figures 1 to 4 shown, in this embodiment, an adjustable point-support oral angle traction device is proposed. The oral angle traction device includes a traction bracket 1, an oral angle support assembly 2, and a viewing mirror assembly 3. The traction bracket 1 includes a main support bracket 4, an oral angle bracket 5, and a viewing mirror bracket 6. Among them, the main support bracket 4 is configured to conform to the contour of the oral cavity when the oral lips are opened. The oral angle bracket 5 has the same contour trend as the main support bracket 4. The oral angle bracket 5 is arranged on the main support bracket 4 and on the side close to the oral cavity. The viewing mirror bracket 6 is arranged on the main support bracket 4 on the side far from the oral cavity. The viewing mirror assembly 3 is movably arranged on the viewing mirror bracket 6. The oral angle support assembly 2 is provided in multiple groups. The oral angle support assembly 2 includes an oral angle support tray 7. The oral angle support tray 7 is movably arranged on the oral angle bracket 5.

[0033] In this embodiment, an adjustable point-support oral angle traction device is disclosed. Its structure is based on the main support bracket 4 that resembles the lip contour when the patient's oral cavity is opened. An oral angle bracket 5 is arranged on the side of the main support bracket 4 close to the lip side, and a viewing mirror bracket 6 is installed on the side far from the lip side. The main support bracket 4, the oral angle bracket 5, and the viewing mirror bracket 6 together serve as the traction bracket 1. The main support bracket 4 has a certain degree of support, and at the same time, the main support bracket 4 also has a certain amount of deformation, which can enable the patient to move the oral cavity slightly to avoid fatigue; multiple oral angle support assemblies 2 are installed on the oral angle bracket 5. Among them, the oral angle support assembly 2 can be set as an oral angle support tray 7. The oral angle support tray 7 is set as an arc-shaped groove tray that can comfortably support the lip side. This is not restrictive and can also be in other forms. The oral angle support tray 7 can move along the oral angle bracket 5. When the patient opens the oral cavity, the doctor can adjust the position of the oral angle support tray 7 according to the condition of the patient's lips and abut it against the lip side position where the patient is not easily injured, reducing the risk of patient injury. The viewing mirror assembly 3 is installed on the viewing mirror bracket 6. The doctor only needs to let the patient open the oral cavity, and the doctor can adjust the position of the viewing mirror assembly 3 on the viewing mirror bracket 6 to observe the inside of the oral cavity, so that the doctor can free both hands and only focus on the oral surgery. The patient only needs to open the oral cavity with the help of the support-type oral angle traction device. Therefore, the difficulty of the doctor's oral surgery is reduced, the situation of the patient's oral angle being injured is avoided, and the patient's experience is improved.

[0034] The oral angle support tray 7 is provided with a threaded hole, and the threaded hole corresponds to the oral angle bracket 5;

[0035] The oral angle support assembly 2 further includes:

[0036] A locking bolt 8, which is threadedly connected to the threaded hole, and the locking bolt 8 can pass through the threaded hole and abut against the oral angle bracket 5.

[0037] In this embodiment, a threaded hole is provided on the oral angle support 7, and the side where the threaded hole penetrates faces the oral angle bracket 5. By installing the locking bolt 8 and tightening the locking bolt 8, the locking bolt will abut against the oral angle bracket 5, thereby locking and clamping the oral angle support 7, improving the stability of the oral angle support 7 and the support stability for the oral and labial parts.

[0038] The main support bracket 4 includes an upper lip side bracket 9 and a lower lip side bracket 10. The upper lip side bracket 9 and the lower lip side bracket 10 are hinged. The oral angle bracket 5 and the mirror bracket 6 are both provided as two disconnected sections and are respectively arranged on the upper lip side bracket 9 and the lower lip side bracket 10;

[0039] The oral angle traction device further includes:

[0040] A limit hinge assembly 11, which is used to connect the upper lip side bracket 9 and the lower lip side bracket 10 and is configured to make the relative rotation angle between the upper lip side bracket 9 and the lower lip side bracket 10 an acute angle.

[0041] Further, referring to Figure 3 , which shows the articulated structure of the main support bracket, and the structures of the remaining parts are the same as those shown in Figure 1 . Here, it will not be elaborated. In this embodiment, the main support bracket 4 can be designed as the upper lip side bracket 9 and the lower lip side bracket 10. The two brackets are both independently arranged and are connected in an articulated form. At the same time, the oral angle bracket 5 and the mirror bracket 6 are also arranged in a segmented form on the upper lip side bracket 9 and the lower lip side bracket 10 respectively, that is, a section of the oral angle bracket 5 is installed on the upper lip side bracket 9, and a section of the oral angle bracket 5 is installed on the lower lip side bracket 10, and the mirror bracket 6 has the same structural form; the upper lip side bracket 9 and the lower lip side bracket 10 are connected by the limit hinge assembly 11 at the hinge. The limit hinge assembly 11 can make the relative rotation angle between the upper lip side bracket 9 and the lower lip side bracket 10 an acute angle, which can not only open the patient's oral cavity, but also allow the patient to move the oral cavity within an allowable range and bite slightly when feeling fatigued without affecting the doctor's operation. It should be noted that the limit hinge assembly 11 only needs to be able to make the relative rotation angle between the upper lip side bracket 9 and the lower lip side bracket 10 an acute angle. Exemplarily, the limit hinge assembly 11 can be in the form of shaft rotation range limitation, setting limit clamping parts to block the bracket rotation range, etc.

[0042] The angular range of relative rotation between the upper lip side bracket 9 and the lower lip side bracket 10 is 5° to 10°.

[0043] On the basis of the above embodiment, the angular range of relative rotation between the upper lip side bracket 9 and the lower lip side bracket 10 can be controlled within 5° to 10°, which can not only provide space for the patient to move, but also not affect the doctor's operation.

[0044] The limiting hinge assembly 11 includes:

[0045] A hinge shaft 12 and a limiting sleeve 13. The limiting sleeve 13 is fixedly arranged inside the lower lip side bracket 10. The limiting sleeve 13 is coaxial with the hinge point of the upper lip side bracket 9 and the lower lip side bracket 10. The limiting sleeve 13 is provided with a first limiting boss 14 and a second limiting boss 15. The central angle range corresponding to the arc between the first limiting boss 14 and the second limiting boss 15 is the same as the angle of relative rotation between the upper lip side bracket 9 and the lower lip side bracket 10;

[0046] The hinge shaft 12 passes through the upper lip side bracket 9 and the lower lip side bracket 10 to form a hinge. The hinge shaft 12 is key-connected to the upper lip side bracket 9. The hinge shaft 12 can move axially on the upper lip side bracket 9. One end of the hinge shaft 12 close to the lower lip side bracket 10 is provided with a stop rod 16. The stop rod 16 can be inserted between the first limiting boss 14 and the second limiting boss 15.

[0047] In this embodiment, the limiting hinge assembly 11 can specifically be implemented by using the hinge shaft 12 in cooperation with the limiting sleeve 13. The hinge shaft 12 passes through the hinge point of the upper lip side bracket 9 and the lower lip side bracket 10. The limiting sleeve 13 is installed inside the hinge of the lower lip side bracket 10. The first limiting boss 14 and the second limiting boss 15 are arranged on the limiting sleeve 13. The hinge shaft 12 can move axially at the hinge of the upper lip side bracket 9 and the lower lip side bracket 10. The hinge shaft 12 is key-connected to the upper lip side bracket 9, that is, the hinge shaft 12 can move along the upper lip side bracket 9, but the upper lip side bracket 9 needs to rotate synchronously with the hinge shaft 12. One end of the hinge shaft 12 close to the lower lip side bracket 10 is provided with a stop rod 16. By moving the hinge shaft 12, the stop rod 16 can be inserted between the first limiting boss 14 and the second limiting boss 15. The central angle corresponding to the arc between the first limiting boss 14 and the second limiting boss 15 is the same as the angle of relative rotation between the upper lip side bracket 9 and the lower lip side bracket 10. Then when the upper lip side bracket 9 rotates relative to the lower lip side bracket 10, it drives the hinge to rotate, and the stop rod 16 of the hinge shaft 12 will be restricted by the first limiting boss 14 and the second limiting boss 15, thereby controlling the angle of relative rotation between the upper lip side bracket 9 and the lower lip side bracket 10.

[0048] The limiting hinge assembly 11 further includes:

[0049] A coil spring 17, wherein the coil spring 17 is sleeved on the hinge shaft 12 and is located between the upper lip side bracket 9 and the lower lip side bracket 10, wherein one end of the coil spring 17 is connected to the upper lip side bracket 9, and the other end is connected to the hinge shaft 12;

[0050] One end of the hinge shaft 12 away from the lower lip side bracket 10 extends out of the end surface of the upper lip side bracket 9 to form an operating end.

[0051] Furthermore, on the basis of the above embodiment, a coil spring 17 is sleeved on the hinge shaft 12, one end of the coil spring 17 is connected to the hinge shaft 12, and the other end is connected to the upper lip side bracket 9, so that the hinge shaft 12 can be pushed out of the key slot of the upper lip side bracket 9 along the axial direction, and then the hinge shaft 12 is rotated to tighten or relax the coil spring 17, and after the adjustment is completed, the hinge shaft 12 is inserted back into the key slot of the upper lip side bracket 9, so that the blocking rod 16 is inserted between the first limiting boss 14 and the second limiting boss 15; when tightened, the elastic force of the coil spring 17 acting on the upper lip side bracket 9 is greater, so that the tendency of the upper lip side bracket 9 and the lower lip side bracket 10 to open is stronger; when the coil spring 17 is relaxed, the elastic force of the coil spring 17 acting on the upper lip side bracket 9 is smaller, so that the tendency of the upper lip side bracket 9 and the lower lip side bracket 10 to open is weaker. Through the above adjustment, the opening force between the upper lip side bracket 9 and the lower lip side bracket 10 can be adjusted more flexibly to support the opening of the patient's mouth. It can also enable the patient to overcome the elastic force of the coil spring 17 when tired and perform small-scale activities and rest, thereby improving the patient's experience.

[0052] An occlusal support portion 18 is further provided inside the upper lip side bracket 9 and the lower lip side bracket 10 , and the occlusal support portion 18 is used for supporting tooth occlusion.

[0053] In this embodiment, an occlusal support portion 18 is also provided. The occlusal support portion 18 is used to support the teeth and is arranged on the side of the upper lip side bracket 9 and the lower lip side bracket 10 close to the teeth. When the patient moves the mouth, part of the teeth can be abutted against the support portion to facilitate movement. The occlusal support portion 18 can be set to be detachable and can be installed in a suitable position according to the patient's dental condition so that the doctor can have a more suitable operating space.

[0054] The mirror assembly 3 comprises:

[0055] A movable seat 19, wherein the movable seat 19 can be locked and arranged on the row of the mirror bracket 6;

[0056] A mirror arm 20 and a lens 21 , wherein one end of the mirror arm 20 is connected to the movable seat 19 , and the other end is connected to the lens 21 .

[0057] In this embodiment, the sight glass assembly 3 is specifically composed of a movable seat 19, a mirror arm 20 and a lens 21. The movable seat 19 is movably arranged on the sight glass bracket 6 and can be locked. The locking method can be bolt locking to achieve fixation. The mirror arm 20 can be a metal flexible arm, and the doctor can bend the metal flexible arm according to needs, so as to place the lens 21 at the position that needs to be observed during the doctor's operation.

[0058] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
