Description

Technical Field

[0001] The present invention relates to the field of oral medical technology, and in particular to an intelligent gingival retractor for oral restoration. Background Art

[0002] In oral fixed restoration (implantation, restoration), it is very important to make accurate impressions. The replication accuracy and detail reproducibility of the neck edge of the abutment tooth directly affect the accuracy and tightness of the neck edge of the patient's restoration. In order to achieve the aesthetics of the anterior teeth and increase the retention of the posterior teeth, the edge of the restoration is often designed to be flush with the gingiva or subgingival. In order to reduce gingival bleeding, obtain a clear field of vision, and make the impression material clearly reproduce the abutment tooth shoulder and gingival sulcus structure, gingival retraction is a common method in clinical practice. The most commonly used gingival retraction technology at present is the mechanical and chemical combined method, that is, the gingival retraction cord is used in combination with chemical drugs. Gingival retraction drugs are divided into vasoconstrictors (such as epinephrine, tetrahydrozoline, oxymetazoline, etc.) and astringents (such as iron sulfate, aluminum sulfate, aluminum chloride, etc.) according to their pharmacological effects. However, the gingival retraction method of mechanically pushing the free gingiva to the root side using a gingival retractor is a very common and frequent clinical operation. This method can fully expose the operation area, effectively avoid damage to the gingiva during the operation, and can also intuitively judge the position of the margin line designed subgingivally.

[0003] In the existing gingival retraction operation, the gingival retraction cord is a coiled wire (similar to the spool of needle and thread), and the physician needs to manually measure the length of the gingival retraction cord and manually cut the gingival retraction cord, which increases the time and difficulty of chairside clinical operation.

DETAILED DESCRIPTION

[0035] The invention discloses an intelligent gingival retractor for oral restoration, which is used to solve the technical problem that in the existing gingival retraction operation, doctors need to manually measure and cut the gingival retraction cord, which increases the clinical operation time and difficulty.

[0036] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 5 , an oral restoration intelligent gingival retractor provided in an embodiment of the present invention comprises a body 1, wherein a control module 9 is disposed in the body 1;

[0038] A gingival retraction head 2 is provided at the first end of the body 1, a wire drum 4 with a gingival retraction cord 5 wound thereon is installed inside the body 1, a wire outlet 6 for the gingival retraction cord 5 to extend out is opened at the first end of the body 1, one end of the wire drum 4 is connected to a first driving member, the first driving member is used to drive the wire drum 4 to rotate so as to send the gingival retraction cord 5 out of the wire outlet 6, and a wire cutting component 7 for cutting the gingival retraction cord 5 is provided at a position of the body 1 near the wire outlet 6;

[0039] The first end of the body 1 is also provided with a camera 3, and the camera 3 is used to identify the shape and position of the patient's teeth;

[0040] The cutting assembly 7, the first driving member and the camera 3 are all electrically connected to the control module 9;

[0041] After the camera 3 identifies the shape and position of the patient's teeth, it transmits the first information to the control module 9. The control module 9 calculates the total gingival margin length of the teeth according to the first information, thereby controlling the first driving member to drive the wire drum 4 to release the gingival line of the length corresponding to the total gingival margin length of the teeth, and controls the wire cutting component 7 to cut the gingival line;

[0042] Specifically, the first driving member in this embodiment is a rotating driving member, and this embodiment does not impose any specific limitation on its structure.

[0043] It should be noted that the control module 9 in this embodiment can accurately identify the shape and position of the teeth through the images obtained by the camera 3 after a certain amount of deep learning and training of oral photos, and can calculate the total gingival margin length of the teeth in the current photo.

[0044] In the oral rehabilitation intelligent gingival retractor of this embodiment, when performing the gingival retractor operation, the doctor can use the camera 3 on the gingival retractor body 1 to identify the patient's teeth to obtain the shape and position of the teeth. After the camera 3 identifies the shape and position of the patient's teeth, it transmits the first information to the control module 9. The control module 9 calculates the total gingival margin length of the teeth according to the first information, thereby controlling the first driving member to drive the wire drum 4 to release the gingival line corresponding to the total gingival margin length of the teeth, and controls the cutting assembly 7 to cut the gingival line. Through the above design, the oral rehabilitation intelligent gingival retractor can intelligently select gingival retractor cords 5 of different lengths according to the shapes and positions of different teeth, realize automatic output of gingival retractor cords 5 of appropriate lengths and cut the gingival retractor cords 5, effectively reduce the clinical operation time and difficulty of the doctor, and improve the treatment efficiency to a certain extent.

[0045] Furthermore, the gingival retraction head 2 in this embodiment is threadedly connected to the first end portion of the fuselage 1 .

[0046] It should be noted that, through the above design, it is easy to replace different gingival extraction heads 2. In addition, in other specific implementations, the gingival extraction head 2 can also be connected to the body 1 in a detachable manner such as snap-fitting, and this embodiment does not limit this.

[0047] Furthermore, the gingival retraction head 2 in this embodiment is a curved gingival retraction head 2 .

[0048] It should be noted that the existing gingival retraction head 2 is generally a flat sheet structure. During gingival retraction, the existing gingival retraction head 2 is only suitable for gingival retraction of teeth in straight areas, but not for teeth in curved areas. The doctor must bend the gingival retraction head 2 to successfully complete the gingival retraction operation, which brings certain inconveniences to the doctor.

[0049] Therefore, in order to solve the above problem, the gingival retraction head 2 in this embodiment can adopt a curved gingival retraction head 2. Through the above design, the gingival retraction head 2 can be suitable for gingival retraction operations on teeth in curved areas, which is more convenient for doctors to operate.

[0050] In addition, the working portion of the gingival retraction head 2 in this embodiment can be a sharp corner or a rounded corner, and this embodiment does not limit this. The physician can select a suitable gingival retraction head 2 according to actual needs.

[0051] Furthermore, the two opposite inner side walls of the body 1 in this embodiment are respectively provided with a first axis 9 and a second axis, and the opposite ends of the bobbin 4 are respectively rotatably connected to the first axis 9 and the second axis;

[0052] An end of the second axis away from the bobbin 4 is connected to an elastic member, and an end of the elastic member away from the second axis is connected to the inner wall of the body 1 .

[0053] It should be noted that, through the above design, the wire drum 4 can be driven to rotate steadily and smoothly to stably deliver the gingival retraction cord 5.

[0054] In addition, the above-mentioned second axis is connected to the inner wall of the fuselage 1 through an elastic member. When the bobbin 4 needs to be removed, the operator can move the second axis toward the inner wall of the fuselage 1 to compress the elastic member. At this time, the second axis is separated from the bobbin 4, and the operator can easily take out the bobbin 4.

[0055] Furthermore, the cutting assembly 7 in this embodiment includes a knife holder, a fixed blade, a movable blade and a second driving member;

[0056] The knife holder is fixed on the body 1, the fixed blade is connected to the knife holder, the second driving member is connected to the knife holder, and the second driving member is connected to the movable blade to drive the movable blade to move toward the fixed blade, so as to cut the gingival retraction cord 5;

[0057] Specifically, the second driving member mentioned above is specifically a linear driving member, and this embodiment does not impose any specific limitation on its structure.

[0058] It should be noted that, through the above design, when the gum retraction cord 5 reaches a preset length, the second driving member drives the movable blade to move toward the fixed blade, thereby cutting the gum retraction cord 5 .

[0059] In addition, the present embodiment does not limit the specific structure of the cutting component 7. The cutting component 7 in the present embodiment may also have other structural forms, which are not introduced one by one in the present embodiment.

[0060] Furthermore, the body 1 of the present embodiment is also provided with control buttons, which include a thread feeding button 12 , a thread retracting button 13 , a thread trimming button 14 and a power on button 15 .

[0061] The thread feeding button 12 , the thread retracting button 13 , the thread trimming button 14 and the power on button 15 are all electrically connected to the control module 9 .

[0062] It should be noted that, through the above design, the physician can also control the delivery and retraction of the gingival retraction cord 5 by pressing buttons.

[0063] In addition, this embodiment may also include other function keys, which are not listed one by one in this embodiment.

[0064] Furthermore, the oral restoration intelligent gingival retractor in this embodiment further includes a touch display screen 11, which is used to display a tooth position map and record the length of the gingival line corresponding to each tooth in the tooth position map and is used for the physician to input a target length of the gingival retraction line 5;

[0065] The touch display screen 11 is electrically connected to the control module 9 .

[0066] It should be noted that, in this embodiment, in addition to real-time feedback of the shape and position of the patient's teeth through the camera 3 so that the wire reel 4 can send out the gingival retraction cord 5 of appropriate length, the doctor can also touch the display screen 11 and select the teeth in the tooth position map. At this time, after receiving the signal, the control module 9 will drive the wire reel 4 to output a gingival cord of a length corresponding to the total gingival margin length of the current tooth.

[0067] In addition, the physician may also manually input the target length of the gingival retraction cord 5 , so that the control module 9 drives the wire drum 4 to output the gingival retraction cord 5 of the target length.

[0068] Furthermore, a cover plate is also provided at a position of the body 1 in this embodiment corresponding to the bobbin 4;

[0069] The cover plate is detachably connected to the body 1 .

[0070] It should be noted that, through the above design, the operator can open the cover to achieve the operation of replacing the bobbin 4.

[0071] Furthermore, an LED light source is disposed at the first end of the body 1 in this embodiment.

[0072] It should be noted that, through the above design, the LED light source can provide light source during the process of the camera 3 acquiring images, so that the camera 3 can acquire clearer images.

[0073] Furthermore, a power supply battery is installed inside the fuselage 1 in this embodiment, and the power supply battery is electrically connected to the control module 9;

[0074] Alternatively, the second end of the body 1 is connected to a power plug.

[0075] It should be noted that, through the above design, the intelligent gingival retractor for oral restoration in this embodiment can work through two different power supply modes.

[0076] The above is a detailed introduction to an intelligent gingival retractor for oral restoration provided by the present invention. For a person skilled in the art, according to the idea of ​​the embodiments of the present invention, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
