Description

Technical Field

[0001] This invention relates to the field of oral auxiliary instruments technology, specifically to an operating space isolation device for oral surgery. Background Technology

[0002] In the field of oral medicine, various clinical procedures place extremely high demands on the clarity of vision and spatial stability of the operating area. Operators must perform precise operations in an undisturbed environment. However, the physiological characteristics of the tongue during swallowing, the continuous secretion of saliva, and the limitations of existing auxiliary instruments have long constrained the improvement of diagnostic and treatment efficiency and outcomes. Currently, commonly used auxiliary fixation and anti-interference solutions in oral procedures have significant shortcomings: instruments that directly clamp teeth can maintain position in the short term, but the clamping force can easily cause additional stress damage to the periodontal ligament, potentially leading to complications such as tooth loosening and periodontal inflammation. Furthermore, the significant differences in tooth morphology among different patients make it difficult to accurately adapt universal clamping structures, easily resulting in unstable clamping or excessive pressure. Additionally, the limited fit between clamping components and the tooth surface allows saliva to easily seep into the operating area, requiring additional moisture-proofing measures. External support-type fixation solutions are complex in structure and cumbersome to install, not only increasing the operator's preparation time but also occupying a significant portion of the oral cavity. The limited operating space hinders the movement and flexibility of instruments such as dental handpieces and orthodontic bonding tools. Furthermore, the poor fit between the support and oral soft tissues makes it ineffective at blocking tongue interference and isolating saliva. It is also prone to displacement due to patient swallowing movements and minor head movements, leading to loss of stability in the operating area and increasing the risk of operational errors. Relying solely on cotton rolls for interference prevention lacks a stable fixing structure, making them prone to displacement with tongue movement or operator manipulation, requiring frequent adjustments. This disrupts the operation rhythm and can lead to cotton fiber shedding and contamination of the operating area. Moreover, it only provides passive interference prevention and cannot fulfill the function of instrument fixation, resulting in a fragmented operation process. These technical defects directly cause a decrease in operational precision, leading to problems such as insufficient marginal fit of restorations and misalignment of orthodontic brackets, increasing the probability of secondary restorations. Simultaneously, patients experience significant discomfort due to frequent instrument adjustments and pressure on oral tissues, resulting in decreased treatment compliance. Operators also need to frequently switch between fixing instruments, adjusting cotton rolls, and precise operation, prolonging treatment time and reducing treatment efficiency. Summary of the Invention

[0003] To address the aforementioned problems in existing technologies, this invention provides an operating space isolation device for oral surgery, which achieves stable fixation without damaging the teeth, while eliminating interference from the tongue and saliva, thus meeting the integrated needs of various oral procedures for fixation and anti-interference.

[0004] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0005] An operating space isolation device for oral surgery includes a vertical part, on which a horizontal part and a limiting part are provided, which are capable of changing the distance between them;

[0006] The horizontal portion is disposed above the vertical portion and extends to one side. The horizontal portion includes two sets of straight segments located on the lingual and buccal sides of the teeth and arranged opposite to each other.

[0007] One of the straight sections on one side has a clearance structure that crosses over and overlaps with the teeth near the vertical part;

[0008] The limiting part is slidably connected to the vertical part in the longitudinal direction, the limiting part extends in the direction of the horizontal part, and a position stabilizing structure is provided between the limiting part and the vertical part.

[0009] In some embodiments of the oral surgery operating space isolation device, the limiting part includes a limiting plate, the vertical part includes a straight rod segment, the limiting plate is slidably connected to the straight rod segment, and the limiting plate has a limiting groove at the position of the straight rod segment;

[0010] The length of the limiting groove in the extending direction of the limiting part is x times the thickness of the straight rod section, where 1 < x < 2, and the limiting piece is made of elastic material.

[0011] In some embodiments of the oral surgery operating space isolation device, the vertical part further includes a folded tail section and a curved section, the lower end of the straight rod section extends in the opposite direction to the horizontal part and has a folded tail section, and the upper end of the straight rod section is fixedly connected to the curved section.

[0012] In some embodiments of the oral surgery operating space isolation device, a limiting protrusion is fixedly connected to the folded tail section, and the radius of the limiting protrusion is larger than the gap between the limiting groove and the straight rod section.

[0013] In some embodiments of the oral surgery operating space isolation device, the horizontal portion further includes an extension section connecting the straight section and the vertical portion, the extension section being fixedly connected to the curved section, wherein the straight section with the avoidance structure is fixedly connected to the extension section through the avoidance structure, and another straight section is fixedly connected to the extension section.

[0014] In some embodiments of the oral surgery operating space isolation device, the avoidance structure is an arched segment, the side of the arched segment near the extension segment is a vertical shape of the outer surface of the tooth, and the side of the arched segment near the straight segment is a sloping structure of the lingual oral cavity of the tooth.

[0015] In some embodiments of the oral surgery operating space isolation device, the limiting piece is fixedly connected to a mating groove at one end corresponding to the lower side of the straight section, the mating groove is recessed downwards, and the limiting piece at the end away from the mating groove corresponds to the folded tail section.

[0016] In some embodiments of the oral surgery operating space isolation device, a plug is fixedly connected to the lower side of the straight section, the plug is inclined and bent away from the straight section, and the end of the plug away from the vertical part is provided with a tip structure.

[0017] In some embodiments of the oral surgery operating space isolation device, the straight section has a raised section in the section away from the vertical part.

[0018] In some embodiments of the oral surgery operating space isolation device, the straight section has a corresponding groove at the corresponding position of the insertion rod.

[0019] In some embodiments of the oral surgery operating space isolation device, a side rod is fixedly connected to the side of the arched segment away from the other straight segment, and a bracket is fixedly connected to the side rod.

[0020] In some embodiments of the oral surgery operating space isolation device, the lower side of the arched segment is provided with a silicone coating.

[0021] In some embodiments of the oral surgery operating space isolation device, there are two styles depending on the side where the arch segment is located.

[0022] The beneficial effects of the oral surgery operating space isolation device disclosed herein are as follows: Through the elastic limiting plate and the deformation-locking engagement of the vertical straight rod section, combined with the overlapping positioning of the horizontal arched section with the teeth, stable fixation of the device can be achieved without directly clamping the teeth. This avoids stress damage to the periodontal ligament caused by traditional clamping methods, and maintains positional stability through the elastic deformation of the limiting plate and the support of the mandible, effectively solving the problems of unstable fixation or tooth damage in existing technologies. The two sets of relatively arranged straight sections in the horizontal section are adapted to the lingual and buccal sides of the teeth respectively. Combined with the insertion rod and the raised section for the stable installation of the cotton roll, circumferential protection of the operating area can be formed, effectively blocking tongue movement interference and isolating saliva intrusion. At the same time, the arched section's structural design, conforming to the tooth shape, improves the fit with the oral cavity... The adaptability of the fabric ensures a consistently reliable anti-interference effect, eliminating the need for additional adjustments to the moisture-proof components and achieving a unified solution for fixation and anti-interference. Fixing and releasing the device requires only simple force; the limiting groove design of the limiting plate and the sliding cooperation of the vertical part make the adjustment process flexible and convenient. The overall structure is compact and does not occupy excessive oral operating space, nor does it interfere with the operator's instrument handling, significantly improving diagnostic and treatment efficiency. Furthermore, the silicone coating on the arched section enhances patient comfort, adapting to different tooth shapes and various oral clinical operation scenarios, effectively reducing the probability of operational errors and the risk of secondary restorations. It also simplifies the operator's procedure, improves patient compliance, and comprehensively meets the integrated needs of oral operations for stable fixation, efficient anti-interference, flexibility, convenience, and comfortable adaptation.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0040] like Figures 1 to 7 As shown, this embodiment of the present disclosure provides an operating space isolation device for oral surgery, including a vertical part, on which a horizontal part and a limiting part that can change the distance between them are provided;

[0041] The horizontal portion is disposed above the vertical portion and extends to one side. The horizontal portion includes two sets of straight segments (210) located on the lingual and buccal sides of the teeth and arranged opposite to each other.

[0042] One of the straight sections (210) has a clearance structure that crosses over the teeth and overlaps with the teeth near the vertical part;

[0043] The limiting part is slidably connected to the vertical part in the longitudinal direction, the limiting part extends in the direction of the horizontal part, and a position stabilizing structure is provided between the limiting part and the vertical part.

[0044] Compared with the prior art, the oral surgery operation space isolation device based on this embodiment uses a stable structure to combine the limiting part with the avoidance structure of the horizontal part to limit and clamp the teeth and mandible. The tongue is limited and controlled by assembling medical accessories such as cotton rolls (5) and gauze blocks on the straight section (210), which presses down the tongue to avoid the problem of the tongue moving involuntarily or interfering with the operation due to swallowing. At the same time, the cotton rolls (5) absorb and shield saliva to keep the periodontal environment of the oral surgery relatively dry.

[0045] like Figure 1 and Figure 4 As shown, in some embodiments, the limiting part includes a limiting piece (3), the vertical part includes a straight rod segment (101), the limiting piece (3) is slidably connected to the straight rod segment (101), and the limiting piece (3) has a limiting groove (302) at the position of the straight rod segment (101).

[0046] The length of the limiting groove (302) in the extending direction of the limiting part is x times the thickness of the straight rod section (101), where 1 < x < 2, and the limiting piece (3) is made of elastic material.

[0047] Compared with the prior art, the oral surgery operating space isolation device based on this embodiment uses a limiting plate (3) of elastic material and a limiting groove (302) to engage with the straight rod section (101). Specifically, the avoidance structure is positioned on the teeth, and the limiting plate (3) moves upward to abut against the mandible and continues to apply upward force, causing the limiting plate (3) to tilt through the limiting groove (302), which is larger than the straight rod section (101), and undergo a slight elastic deformation. The limiting plate (3) is pressed and contacted with the straight rod section (101) at the position of the limiting groove (302). After releasing the pressure, the limiting plate (3) Under the avoidance structure, the force between the limiting piece (3) and the mandible is stable, maintaining the deformed state. The inclined limiting piece (3) moves away from the horizontal part but in a different direction from the straight rod section (101), forming a state in which the limiting piece (3) is engaged with the straight rod section (101) through the limiting groove (302). When it is necessary to release, the limiting piece (3) and the vertical part are controlled to apply force, so that the limiting piece (3) is restored to the horizontal, and the vertical part is deformed relative to each other, so that the limiting groove (302) of the limiting piece (3) is restored to the vertical sliding connection state with the straight rod section (101), so that the limiting piece (3) slides down to complete the release.

[0048] like Figure 2 As shown, in some embodiments, the vertical part further includes a folded tail section (102) and a curved section (104). The lower end of the straight rod section (101) extends in the opposite direction to the horizontal part and is provided with a folded tail section (102). The upper end of the straight rod section (101) is fixedly connected with a curved section (104).

[0049] Compared with the prior art, the operating space isolation device for oral surgery based on this embodiment provides the surgeon with a convenient grip and force application point for the folded tail section (102), avoiding hand slippage during operation; the curved section (104) adapts to the contours of the lips and jaws during oral surgery, making room for space and reducing friction damage between the device and the buccal and palatal mucosa.

[0050] like Figure 2 As shown, in some embodiments, a limiting convex ball (103) is fixedly connected to the tail section (102), and the radius of the limiting convex ball (103) is greater than the gap between the limiting groove (302) and the straight rod section (101).

[0051] Compared with the prior art, the operating space isolation device for oral surgery based on this embodiment can effectively prevent the limiting ball (103) from accidentally disengaging from the straight rod section (101) when the limiting piece (3) slides downward. It can also maintain a unified whole after cleaning, keep the integrity of the device structure, avoid loss, and improve the safety and reliability of the device.

[0052] like Figure 3As shown, in some embodiments, the horizontal portion further includes an extension (201) connecting the straight section (210) and the vertical portion, the extension (201) being fixedly connected to the curved section (104), wherein the straight section (210) with the avoidance structure is fixedly connected to the extension (201) through the avoidance structure, and another straight section (210) is fixedly connected to the extension (201).

[0053] Based on the oral surgery operating space isolation device of this embodiment, compared with the prior art, the extension section (201) serves as a transitional connection structure, enabling the two sets of straight sections (210) to adapt to the spatial layout of the lingual and buccal sides of the teeth.

[0054] like Figure 2 and Figure 5 As shown, in some embodiments, the avoidance structure is an arched segment (220), the arched segment (220) having a vertical shape on the side near the extension segment (201) resembling the outer surface of a tooth, and the arched segment (220) having a sloping structure on the lingual side of the oral cavity resembling the tooth on the side near the straight segment (210).

[0055] Compared with the prior art, the hyperboloid structure of the arch segment (220) of the oral surgery operation space isolation device based on this embodiment precisely fits the outer surface of the tooth and the lingual contour, and achieves the connection with the tooth. It not only avoids the spatial position of the tooth and completes the transition to the lingual direction, but also forms a supporting relationship with the tooth, providing the first force point for subsequent positioning.

[0056] like Figure 2 and Figure 4 As shown, in some embodiments, the limiting piece (3) is fixedly connected to a mating groove (301) at one end corresponding to the lower side of the straight section (210), the mating groove (301) is recessed downward, and the limiting piece (3) is aligned with the folded tail section (102) at one end away from the mating groove (301).

[0057] Compared with the prior art, the concave structure of the groove (301) of the oral surgery operation space isolation device based on this embodiment can fit the contour of the mandible, increase the contact area between the limiting piece (3) and the mandible, make the supporting force more evenly distributed, avoid excessive local pressure causing discomfort to the patient's mandible, and at the same time improve the fitting stability between the limiting piece (3) and the mandible, further enhancing the overall fixation effect of the device.

[0058] like Figure 5 As shown, in some embodiments, a plug rod (230) is fixedly connected to the lower side of the straight section (210), the plug rod (230) is inclined and bent away from the straight section (210), and the end of the plug rod (230) away from the vertical part is provided with a tip (231) structure.

[0059] Based on the oral surgery operating space isolation device of this embodiment, compared with the prior art, the inclined and curved insertion rod (230) combined with the insertion tip (231) structure can be used to position the middle position of the cotton roll (5) during the installation of the cotton roll (5), so as to avoid the cotton roll (5) from shifting when the tongue moves or the surgeon operates.

[0060] like Figure 2 As shown, in some embodiments, the straight section (210) has a raised section (211) in the section away from the vertical portion.

[0061] Compared with the prior art, the operating space isolation device for oral surgery based on this embodiment facilitates the insertion of cotton rolls (5) by cooperating with the lifting section (211) and the insertion rod (230); the guide slope formed by the lifting section (211) guides the cotton rolls (5) to be quickly put into the insertion rod (230), reducing the difficulty of installing cotton rolls (5) and improving the efficiency of preoperative preparation.

[0062] like Figure 3 As shown, in some embodiments, the straight section (210) has a corresponding groove (212) at the corresponding position of the insert (230).

[0063] Compared with the prior art, the operating space isolation device for oral surgery based on this embodiment squeezes the cotton roll (5) into the space between the insert (230) and the straight section (210), and the corresponding groove (212) can accommodate part of the structure of the squeezed cotton roll (5), so that the cotton roll (5) and the straight section (210) fit more tightly, making the installation state more stable and maintaining the saliva isolation effect.

[0064] like Figure 6 and Figure 7 As shown, in some embodiments, a side rod (4) is fixedly connected to the side of the arched segment (220) away from the straight segment (210) on the other side, and a bracket (401) is fixedly connected to the side rod (4).

[0065] Compared with the prior art, the operating space isolation device for oral surgery based on this embodiment can expand the function of the device by using the side rod (4) and the bracket (401) to fix additional auxiliary components such as suction tubes, adapt to complex oral surgery scenarios, and improve the versatility and practicality of the device.

[0066] In some embodiments (not shown), the underside of the arch segment (220) is provided with a silicone coating.

[0067] Compared with the prior art, the silicone coating of the oral surgery operation space isolation device based on this embodiment has good elasticity, which can reduce the force and friction damage between the arch segment (220) and the teeth, while enhancing the tightness of the fit between the arch segment (220) and the teeth, and improving the anti-slip effect and saliva isolation performance.

[0068] like Figure 1 As shown, in some embodiments, there are two styles depending on the side where the arch segment (220) is located.

[0069] like Figure 8 and Figure 9 As shown in some embodiments, this illustrates the effect of the solution of this disclosure in actual implementation with the human body and its positioning.

[0070] Compared with the prior art, the two styles of the oral surgery operation space isolation device based on this embodiment are adapted to the operation needs of the left and right sides of the teeth respectively, matching the shape of the teeth on different sides and the oral space layout, and meeting the needs of diverse clinical operation scenarios.
