Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an oral orthodontic mouth opener. Background Technology

[0002] In clinical orthodontics, delicate procedures such as bracket bonding, archwire adjustment, and chain traction highly depend on a stable and open surgical field and a dry operating environment. Mouth openers (also known as oral retractors) are the core instruments for achieving this goal. Their basic mission is to maintain the patient's mouth in a constant open state and effectively pull and isolate soft tissues such as the lips and cheeks, creating a clear and unobstructed operating channel for the physician.

[0003] Existing mouth openers mostly use a single size or fixed structure, relying solely on material elasticity or rigid tension to maintain the opening. However, there are significant differences in the width of the dental arch and the fullness of soft tissue among different patients, and throughout the treatment process, the dentist may need to dynamically adjust the opening degree according to different operating sites. However, existing mouth openers cannot respond to this "personalized" and "dynamic" demand, resulting in problems such as concentrated pressure points and excessive local stress during application, which can easily cause patient discomfort or even pain, seriously affecting the tolerance and experience of long-term treatment. In addition, regarding the exposure of the surgical field, the fixed-angle labial guards provided by existing mouth openers have extremely limited traction ability in the posterior teeth region, especially the molar region, exposing a structural shortcoming of "insufficient force". In order to obtain a sufficient field of vision in the posterior teeth region, the dentist needs to use cheek hooks or manual assistance from an assistant, which not only affects the continuity of orthodontic operation, but also introduces uncertainties, affecting the accuracy and efficiency of treatment. Summary of the Invention

[0004] This invention aims to provide an orthodontic mouth opener that utilizes an adjustment component to regulate the filling state of a flexible adjustment sac inside the upper lip support portion, thereby adjusting different degrees of opening and improving comfort when opening the upper lip. Furthermore, by adjusting the connection position and angle between the cheek opening component and the mouth opener body, the opening position can be adjusted to expose the corresponding visual field. This solves the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An orthodontic mouth opener includes an Ω-shaped mouth opener body made of elastic material, the mouth opener body being connected to a handle for controlling its deformation; an upper lip support portion is provided on the upper side of the mouth opener body, the upper lip support portion having a groove, a flexible adjustment sac being provided inside the groove, the upper lip support portion being connected to an adjustment component for controlling the inflation state of the flexible adjustment sac, the flexible adjustment sac being connected to a control valve for controlling its communication with and / or isolation from the outside world; cheek opening components are adjustablely connected to both the left and right sides of the mouth opener body.

[0007] Furthermore, the adjusting assembly includes an outer cylinder and a piston assembly. The outer cylinder is fixedly connected to the upper lip support. The piston of the piston assembly is slidably and sealingly connected to the inner wall of the outer cylinder. The operating rod of the piston assembly is connected to the opening device body. The outer cylinder is connected to the flexible adjusting bladder through a conduit. When the opening device body deforms, the operating rod of the piston assembly drives the piston to move inside the outer cylinder, controlling the fluid flow between the inner side of the outer cylinder and the inner side of the flexible adjusting bladder, thereby controlling the filling state of the flexible adjusting bladder.

[0008] Furthermore, the middle part of the conduit is connected to the conductive end of the outer cylinder, and the conduits at both ends of the outer cylinder are equipped with one-way valves. The one-way valve between the outer cylinder and the flexible regulating bladder controls the fluid to flow from the outer cylinder to the flexible regulating bladder side, and the other one-way valve controls the fluid to flow from the outside to the outer cylinder side.

[0009] Furthermore, the flexible regulating bladder is an air bladder or a liquid bladder; when the flexible regulating bladder is an air bladder, the one-way valve is a gas one-way valve; when the flexible regulating bladder is a liquid bladder, the one-way valve is a liquid one-way valve.

[0010] Furthermore, the cheek support is connected to the mouth opener body via an adjusting member, the adjusting member is connected to the mouth opener body via a thread, and the cheek support and the adjusting member are detachably connected.

[0011] Furthermore, the side wall of the mouth opener body is provided with an adjustment hole, the adjustment member is provided with a plurality of locking holes evenly distributed, and the cheek support member is connected with a locking member that is configured to cooperate with the locking holes. After the locking member passes through the adjustment hole, it is press-fitted into the locking hole.

[0012] Furthermore, it also includes a saliva suction tube, and the mouth opener body is detachably connected to a collar that cooperates with the saliva suction tube. After passing through the collar, the saliva suction tube is used to suction accumulated liquid, and the suction end of the saliva suction tube is connected to a suction ball.

[0013] Furthermore, the collar has an opening on one side, and there is an interference fit between the collar and the mouth opener body and between the saliva suction tube and the collar, with an interference amount of 0.5~1mm.

[0014] Furthermore, the mouth opening body is made of low-density polyethylene, medical-grade silicone, or thermoplastic polyurethane.

[0015] Furthermore, the Shore A hardness of the opening body is between 30 and 50.

[0016] The principles and beneficial effects of the technical solution are as follows:

[0017] 1. The present invention provides an orthodontic mouth opener, comprising a mouth opener body made of elastic material, an upper lip support portion on the upper side of the mouth opener body, a flexible adjustment sac within a groove of the upper lip support portion, and an adjustment component connected to the upper lip support portion to control the filling state of the flexible adjustment sac. The adjustment component is used to adjust the filling state of the flexible adjustment sac to adapt to different opening requirements. Moreover, the upper lip contacts the flexible adjustment sac, providing good comfort during the opening process and effectively avoiding problems such as concentrated pressure points and excessive local stress. The left and right sides of the mouth opener body are adjustablely connected to cheek opening components, which are used to open the left and right cheeks respectively. By adjusting the connection position and angle between the opening components and the mouth opener body, the opening position can be adjusted to expose the corresponding visual field, thereby improving the accuracy and efficiency of treatment.

[0018] 2. The present invention provides an orthodontic mouth opener, the adjustment component of which includes an outer cylinder and a piston assembly. The conductive end of the outer cylinder is connected to a flexible adjustment bladder via a conduit. When the mouth opener body is deformed by controlling the handle, the operating rod of the piston assembly moves with the movement of the mouth opener body, causing fluid to flow between the outer cylinder and the flexible adjustment bladder, thereby adjusting the filling state of the flexible adjustment bladder. Specifically, the middle part of the conduit is connected to the conductive end of the outer cylinder, and both ends of the conduit are equipped with one-way valves, and the one-way valve between the outer cylinder and the flexible adjustment bladder controls the flow. The fluid flows from the outer cylinder to the flexible adjustment bladder side, while another one-way valve controls the flow of fluid from the outside to the outer cylinder side. This causes the mouth opener body to deform periodically when the handle is pressed periodically. The operating rod of the piston assembly drives the piston to move periodically inside the outer cylinder, injecting the fluid from the outside into the flexible adjustment bladder and making it full. In other words, by controlling the number of times the handle / mouth opener body deforms, the fullness of the flexible adjustment bladder can be controlled to adapt to different clinical needs. It is easy to operate, reliable in function, and has a simple and compact overall structure, which can effectively reduce the obstruction of the surgical field. More specifically, the fluid can be selected as gas or liquid, and the corresponding flexible adjustment bladder is an air bladder or a liquid bladder. The one-way valve is a gas one-way valve or a liquid one-way valve. When the fluid is gas, the end of the conduit away from the flexible adjustment bladder is directly connected to the outside. The inflation state of the flexible adjustment bladder can be controlled by periodically pressing the handle. The amount of gas in the environment is sufficient and the structure is simple. When the fluid is liquid, the end of the conduit away from the flexible adjustment bladder is connected to an external container storing liquid. By controlling the temperature of the liquid in the container, the liquid entering the flexible adjustment bladder also has a corresponding temperature, which can further improve the comfort during the expansion process.

[0019] 3. The present invention provides an orthodontic mouth opener, wherein a cheek support is connected to the mouth opener body via an adjusting member. The adjusting member is connected to the mouth opener body via a thread, and the cheek support and adjusting member are detachably connected. By adjusting the connection position and relative angle between the adjusting member and the mouth opener body, the relative position and angle of the cheek support relative to the mouth opener body can be adjusted, allowing the support and exposure field of view to be adjusted according to clinical needs, thereby improving the accuracy and efficiency of treatment. An adjusting hole is provided on the side wall of the mouth opener body, and the adjusting member is connected to a locking hole. The cheek support is connected to a locking member, which passes through the adjusting hole and engages with the locking hole. This allows the angle of the cheek support to be adjusted within a certain angle even when the adjusting member is connected to the mouth opener body, further improving the ease of operation.

[0020] 4. The present invention provides an orthodontic mouth opener, wherein the mouth opener body is connected to a collar with an opening on one side. The collar is press-fitted with a saliva suction tube, and the suction end of the saliva suction tube is connected to a suction device. The saliva suction tube can be used to drain the fluid in the patient's mouth to the outside, which can further improve the surgical field and reduce the patient's discomfort. The collar and the mouth opener body and the saliva suction tube and the collar are both press-fitted, and the press-fit is 0.5~1mm. This makes the relative position of the two connected (the collar and the mouth opener body, the saliva suction tube and the collar) stable and adjustable, further improving the stability and convenience during use.

[0021] 5. The present invention provides an orthodontic mouth opener, the mouth opener body of which is made of low-density polyethylene, medical-grade silicone or thermoplastic polyurethane material, all of which have high biocompatibility, flexibility and corresponding elastic / mechanical properties; and its Shore A is controlled between 30 and 50, which ensures that the mouth opener body effectively balances the core contradiction of "softness without damaging tissue" and "toughness without losing its shape", thereby ensuring the comfort, support and durability of the mouth opener.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0029] like Figures 1 to 4 As shown, an orthodontic mouth opener includes a mouth opener body 1 and a saliva suction tube 7. The mouth opener body 1 is made of elastic material and is Ω-shaped. The Shore A hardness of the mouth opener body 1 is between 30 and 50. The left and right ends of the lower side of the mouth opener body 1 are connected to handles 6 to control its deformation.

[0030] The upper side of the mouth opener body 1 is provided with an upper lip support 2, which has a groove. A flexible adjustment bladder 4 is provided inside the groove. The upper lip support 2 is connected to an adjustment component 3 for controlling the inflation state of the flexible adjustment bladder 4. The adjustment component 3 includes an outer cylinder 8 and a piston assembly 9. The outer cylinder 8 is fixedly connected to the upper lip support 2. The piston of the piston assembly 9 is slidably sealed to the inner wall of the outer cylinder 8. The operating rod of the piston assembly 9 is connected to the mouth opener body 1. The outer cylinder 8 is connected to the flexible adjustment bladder 4 through a conduit 10. The middle part of the conduit 10 is connected to the conducting end of the outer cylinder 8 and is located at both ends of the outer cylinder 8. Each conduit 10 is equipped with a one-way valve 11. The one-way valve 11 between the outer cylinder 8 and the flexible regulating bladder 4 controls the flow of fluid from the outer cylinder 8 to the flexible regulating bladder 4. Another one-way valve 11 controls the flow of fluid from the outside to the outer cylinder 8. When the opening device body 1 deforms, the operating rod of the piston assembly 9 drives the piston to move inside the outer cylinder 8, controlling the flow of fluid between the inner side of the outer cylinder 8 and the inner side of the flexible regulating bladder 4, so as to control the filling state of the flexible regulating bladder 4. The flexible regulating bladder 4 is connected to a control valve (not shown in the figure) to control its communication with and / or isolation from the outside.

[0031] Both sides of the mouth opener body 1 can be adjusted and connected to cheek support members 5; specifically, the cheek support member is connected to the mouth opener body 1 through the adjustment member 13, the adjustment member 13 is connected to the mouth opener body 1 through the thread, the side wall of the mouth opener body 1 is provided with adjustment holes, the adjustment member 13 is evenly provided with a number of locking holes 14, the cheek support member is connected to the locking member 15 that is configured to cooperate with the locking hole 14, and the locking member 15 passes through the adjustment hole and is press-fitted with the locking hole 14.

[0032] The mouth opener body 1 is detachably connected to a collar 12 that cooperates with the saliva suction tube 7. The saliva suction tube 7 passes through the collar 12 and is used to suction the accumulated liquid. The suction end of the saliva suction tube 7 is connected to a suction ball 16. The collar 12 is open on one side. The collar 12 and the mouth opener body 1 and the saliva suction tube 7 and the collar 12 are both interference fit, and the interference amount is 0.5~1mm.

[0033] In this embodiment, the mouth opening body 1 is made of low-density polyethylene, medical-grade silicone or thermoplastic polyurethane; the flexible adjustment bladder 4 is an air bladder, and the one-way valve 11 is a gas one-way valve 11.

[0034] In other embodiments, the flexible regulating bladder 4 can be a liquid bladder, the one-way valve 11 can be a liquid one-way valve 11, and the liquid one-way valve 11 on the side of the conduit 10 away from the liquid bladder is connected to an external container holding liquid.

[0035] The specific implementation process is as follows:

[0036] When using this mouth opener, first, adjust the relative positions of the two adjusting pieces 13 to the mouth opener body 1 by rotating them according to the patient's dental arch width and soft tissue fullness. Then, insert the clip 15 connected to the cheek expander 5 through the adjusting hole and into the clip hole 14. At the same time, use the handle 6 to periodically press the mouth opener body 1 to change the filling state of the flexible adjusting bladder 4. Then, according to clinical needs, insert the suction tube 7 into the collar 12 and then attach the collar 12 to the mouth opener body 1. Finally, place the mouth opener body 1 into the patient's oral cavity, with the upper lip support 2 abutting against the upper lip and the cheek expanders 5 on the left and right sides abutting against the left and right cheeks respectively. The doctor can then perform orthodontic operations. During this process, the suction ball 16 connected to the suction tube 7 can be placed at the site of fluid accumulation to drain the fluid in the oral cavity to the outside. Adjust the adjusting piece 13 as needed to change the angle of the cheek expander 5 relative to the mouth opener body 1, thereby exposing the corresponding field of vision to facilitate orthodontic operations.

[0037] When the handle 6 is pressed periodically, the mouthpiece body 1 undergoes periodic deformation. The operating rod of the piston assembly 9 drives the piston to move periodically inside the outer cylinder 8, injecting external gas into the inner side of the flexible regulating bladder 4, making it full. In other words, by controlling the number of times the handle 6 / mouthpiece body 1 is pressed, the fullness of the flexible regulating bladder 4 can be controlled to adapt to different clinical needs.
