Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a rubber barrier punch. Background Technology

[0002] An oral rubber dam (also called a moisture-proof rubber dam) is used to isolate teeth, preventing saliva from flowing into the dental work area. Since dental fillings can be contaminated with saliva or blood during use, potentially leading to treatment failure, liquid isolation is crucial. Water sprayed by dental instruments is prevented from flowing into the patient's mouth by the rubber dam, eliminating the need for suction and avoiding gagging. The rubber dam also protects soft oral tissues (including lips, cheeks, and tongue) from injury by dental instruments.

[0003] Rubber dams require perforation before use to fit onto the corresponding teeth. Human teeth are mainly divided into incisors, canines, premolars, and molars. Due to the different sizes of teeth, holes of different diameters need to be drilled for each tooth to ensure a firm fit. Existing instruments for perforating rubber dams are usually simple punches and rotary punches. Both of these punches create holes through compression, resulting in problems such as uneven perforation, burrs, cracks, and even failure to cut out the holes.

[0004] Patent CN218083124U discloses a hole punch, which requires adjusting the position of the punch blade each time a hole is punched to align it with the punch holder. This necessitates multiple adjustments to the punch blade position when punching holes of different diameters, wasting operator time and reducing punching efficiency.

[0005] Patent CN212522679U discloses a punching device that requires a fixing component to secure the wound dressing and a punching component to punch holes in the wound dressing in cooperation to complete the punching process. A distance locking component fixes the moving arm at different positions on an adjusting plate, thereby adjusting the distance between the fixing puncture component and the moving puncture component, thus allowing adjustment of the distance between the two as needed. The user can hold the punching component to punch holes in the wound dressing, resulting in a wound dressing with evenly distributed holes. This solution can control the spacing of the holes, but cannot control the size of the holes. Summary of the Invention

[0054] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0055] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0056] Example 1

[0057] Reference Figure 1 , Figure 6 and Figure 7 A rubber barrier puncher includes a puncher body 1, which includes a fixing mechanism 2 and a moving mechanism 3. The fixing mechanism 2 and the moving mechanism 3 are movable relative to each other. The fixing mechanism 2 includes a fixing part 201 and a punching part 202 located at the front end of the fixing part 201. The punching part 202 includes a punching rod 2021, which is a multi-stage stepped rod. The moving mechanism 3 includes a moving part 301 and a receiving part 302 located inside the moving part 301. The receiving part 302 includes multiple receiving sleeves 3021, which are sequentially sleeved. The punching rod 2021 and the receiving sleeves 3021 are correspondingly arranged. The receiving sleeves 3021 can be compressed into the receiving part 302 under the action of the punching rod 2021 to punch holes in the rubber barrier covering the surface of the moving mechanism 3 and the rubber barrier on the surfaces of the multiple receiving sleeves 3021.

[0058] In the un-drilled state, there is a gap between the stamping rod 2021 and the receiving sleeve 3021. At this time, the rubber barrier is placed on the surface of the receiving sleeve 3021 in preparation for drilling.

[0059] During the drilling process, because the rubber barrier covers the surface of the receiving sleeve 3021, the moving mechanism 3 moves toward the fixed mechanism 2. The end of the punching rod 2021 is sharp, which punches and shears the rubber barrier onto the receiving sleeve 3021. The receiving sleeve 3021 is compressed into the receiving part 302. As the moving distance changes, holes of different diameters can be punched out of the rubber barrier.

[0060] When the punching is complete, the moving mechanism 3 moves away from the fixed mechanism 2, the receiving sleeve 3021 returns to the unpunched state, and the sheared rubber barrier pops out from the receiving sleeve 3021 to prepare for the next punching.

[0061] Reference Figure 6The stamping part 202 also includes a stamping seat 2022. The end of the stamping rod 2021 is located at the front end of the stamping seat 2022, and the ends of the stamping rod 2021 are aligned with the same vertical surface. The stamping rod 2021 and the stamping seat 2022 are detachably installed. Because the end of the stamping rod 2021 may become dull due to repeated stamping processes, the stamping rod 2021 can be unloaded from the stamping seat 2022, the end of the stamping rod 2021 can be ground, and after it is sharpened, the stamping rod 2021 can be reinstalled on the stamping seat 2022.

[0062] The stamping base 2022 and the stamping rod 2021 are coaxially arranged. One end of the multi-stage stepped stamping rod is aligned and installed inside the stamping base 2022, and the other end of the multi-stage stepped rod is distributed in a stepped shape along its own axial direction to stamp and shear the rubber barrier. The multi-stage stepped rod includes a first stamping rod 20211, a second stamping rod 20212, a third stamping rod 20213, a fourth stamping rod 20214, and a fifth stamping rod 20215 with gradually increasing diameters. During the forward stamping and shearing process of each step of the stamping rod, holes of different diameters can be obtained at the same position on the rubber barrier.

[0063] Reference Figure 7 The movable part 301 includes a movable housing 3011 and a movable plate 3012. The front end of the movable part 301 is provided with a receiving groove 3013, in which the movable plate 3012 can be detachably installed. The receiving part 302 is located above the receiving groove 3013, so that the receiving part 302 does not interfere with the movable housing 3011 and can cooperate with multi-stage stepped rods to drill holes of different diameters.

[0064] Reference Figure 2 The movable plate 3012 includes a plate 30121 and a first rack 30122, a second rack 30123 and a third rack 30124 laid flat on the plate 30121. The second rack 30123 is installed between the first rack 30122 and the third rack 30124. The first rack 30122 and the third rack 30124 are symmetrically arranged about the second rack 30123 as an axis.

[0065] Reference Figure 1The first rack 30122, the second rack 30123, and the third rack 30124 each have multiple first straight teeth 301221, second straight teeth 301231, and third straight teeth 301241 evenly distributed on them. The tooth width of each second straight tooth 301231 is greater than the tooth width of each first straight tooth 301221 and each third straight tooth 301241, and the tooth thickness of each second straight tooth 301231 is greater than the tooth thickness of each first straight tooth 301221 and each third straight tooth 301241. The tooth pitch of any adjacent first straight tooth 301221 or third straight tooth 301241 is greater than the tooth pitch of any adjacent second straight tooth 301231. By setting different tooth widths and tooth thicknesses, the transmission distance between the second rack 30123 and the first rack 30122 and the third rack 30124 is different. Generally, the tooth width and thickness of the second spur tooth 301231 are twice that of the first spur tooth 301221 and the third spur tooth 301241. With this configuration, after drilling the smallest diameter hole, the second rack 30123 can quickly drill a third diameter hole, improving drilling efficiency. If a second smallest diameter hole is desired, the combined action of the first spur tooth 301221 and the third spur tooth 301241 reduces meshing resistance, achieving multiple rapid transmissions and further improving drilling efficiency.

[0066] The first straight tooth 301221, the second straight tooth 301231, and the third straight tooth 301241 are vertical surfaces near the fixed part 201, and inclined surfaces away from the fixed part 201, with the inclined surfaces at a certain angle to the vertical surfaces. This setting can limit the rack and pinion transmission process, allowing transmission only in one direction and preventing the moving plate 3012 from naturally reversing.

[0067] Reference Figure 8 The receiving part 302 also includes a first spring 3022, a first annular plate 3023, a second spring 3024, a second annular plate 3025, a third spring 3026, a third annular plate 3027, a fourth spring 3028, a fourth annular plate 3029, a fifth spring 3030, and a fifth annular plate 3031 that abut against each other in sequence. The multiple receiving sleeves 3021 are coaxial sleeves, arranged sequentially from the inside out. Each coaxial sleeve includes a first sleeve 3032, a second sleeve 3033, a third sleeve 3034, a fourth sleeve 3035, and a fifth sleeve 3036 that are capable of relative movement. The ends of the coaxial sleeves facing the fixing part 201 are flush and used to receive the multi-stage stepped stamping rod during stamping and shearing.

[0068] The first annular plate 3023, the second annular plate 3025, the third annular plate 3027, the fourth annular plate 3029, and the fifth annular plate have a hollow structure in the middle. This allows the sleeve to pass through, enabling the sleeve to compress inward while in contact with the stamping rod; under the action of the spring, the sleeve can return to its initial state after shearing the rubber barrier.

[0069] The first sleeve 3032 passes through the second annular plate 3025, the third annular plate 3027, the fourth annular plate 3029, and the fifth annular plate 3031 before being fixedly connected to the first annular plate 3023; the second sleeve 3033 passes through the third annular plate 3027, the fourth annular plate 3029, and the fifth annular plate 3031 before being fixedly connected to the second annular plate 3025; the third sleeve 3034 passes through the fourth annular plate 3029 and the fifth annular plate 3031 before being fixedly connected to the third annular plate 3027; the fourth sleeve 3035 passes through the fifth annular plate 3031 before being fixedly connected to the fourth annular plate 3035; and the fifth sleeve 3036 is directly fixedly connected to the fifth annular plate 3031.

[0070] Reference Figure 1 and Figure 8 The stamping rod 2021 and the receiving sleeve 3021 are coaxially opposite each other, enabling holes of different diameters to be punched. The end diameter of the first stamping rod 20211 is between the inner and outer diameters of the first sleeve 3032; the end diameter of the second stamping rod 20212 is between the inner and outer diameters of the second sleeve 3033; the end diameter of the third stamping rod 20213 is between the inner and outer diameters of the third sleeve 3034; the diameter of the fourth stamping rod 20214 is between the inner and outer diameters of the fourth sleeve 3035; and the diameter of the fifth stamping rod 20215 is between the inner and outer diameters of the fifth sleeve 3036.

[0071] Reference Figure 9 The receiving part 302 also includes a protective cover 3037, which is located at the outermost end of the receiving part 302. Two limiting holes 30371 are correspondingly provided on the upper and lower front parts of the protective cover 3037, and two limiting grooves 30361 are correspondingly provided on the upper and lower front parts of the fifth sleeve 3036. A limiting block 3038 is inserted into the limiting holes 30371 and the limiting grooves 30361 to connect the protective cover 3037 and the fifth sleeve 3036. The protective cover can prevent dust from entering the interior of the receiving part 302, improving the hygiene environment inside the receiving part 302.

[0072] Reference Figure 1 The fixing part 201 includes a hand-held part 2011 and a fixing part 2012, which are integrally formed or detachably connected. The hand-held part 2011 is located at the lower end of the fixing part 2012, and the front end of the fixing part 2012 is connected to the stamping part 202.

[0073] Reference Figure 1The handheld component 2011 includes a handle 20111, a first trigger 20112, and a second trigger 20113. The first trigger 20112 and the second trigger 20113 are movably connected to the handle 20111. The second trigger 20113 is located in front of the first trigger 20112. By pressing the first trigger 20112 and the second trigger 20113, the movement of the movable plate 3012 is realized. The handle 20111 has multiple inner grooves in front for easy gripping, which is convenient and conforms to ergonomics.

[0074] Reference Figure 3 The fixing part 201 also includes a sliding device 2013, which includes a sliding side frame 20131 and a sliding rod assembly 20132. The sliding side frame 20131 is hinged to the handle 20111, allowing the sliding side frame 20131 to rotate downwards, thus releasing the moving plate from the engagement force restriction and enabling manual dragging of the moving plate away from the fixing part 201. The sliding side frame 20131 provides sliding space for the sliding rod assembly 20132, which is engaged with the moving plate 3012, enabling the second trigger 20113 and the first trigger 20112 to drive the moving plate 3012 towards the fixing part 201.

[0075] Reference Figure 3 The sliding side frame 20131 has a front-to-back sliding groove 201311 inside, and the sliding rod assembly 20132 slides within the sliding groove 201311. A pressure plate 20133 is installed at the front of the sliding side frame 20131. The pressure plate 20133 drives the sliding side frame 20131 to press down clockwise around the handle 20111, causing the sliding side frame 20131 to briefly separate from the moving plate 3012, and moving the moving plate 3012 away from the fixed part.

[0076] Reference Figure 3 and Figure 4The sliding rod assembly 20132 includes a first sliding rod assembly 20132a and a second sliding rod assembly 20132b. The first sliding rod assembly 20132a is located behind the second sliding rod assembly 20132b. The first sliding rod assembly 20132a includes a first sliding horizontal rod 20132a1, a first sliding vertical rod 20132a2 and a first limiting plate 20132a3 connected in sequence. The second sliding rod assembly 20132b includes a second sliding horizontal rod 20132b1, a second sliding vertical rod 20132b2 and a second limiting plate 20132b3 connected in sequence. The first sliding crossbar 20132a1 slides within the sliding groove 201311; the lower part of the first sliding vertical bar 20132a2 is perpendicular to the first sliding crossbar 20132a1; the upper part of the first sliding vertical bar 20132a2 is connected to the first limiting plate 20132a3; the second sliding crossbar 20132b1 slides within the sliding groove 201311; the lower part of the second sliding vertical bar 20132b2 is perpendicular to the second sliding crossbar 20132b1; the upper part of the second sliding vertical bar 20132b2 is connected to the second limiting plate 20132b3. The first limiting plate 20132a3 has a first limiting tooth 20132a31 and a third limiting tooth 20132a32 at its end, with a gap between them. The first limiting tooth 20132a31 and the third limiting tooth 20132a32 correspond to the first rack 30122 and the third rack 30124, respectively. The second limiting plate 20132b3 has a second limiting tooth 20132b31 at its end, which corresponds to the second rack 30123.

[0077] The first limiting tooth 20132a31, the third limiting tooth 20132a32, and the second limiting tooth 20132b31 respectively engage with the first straight tooth 301221, the third straight tooth 301241, and the second straight tooth 301231 for limiting. The second limiting tooth 20132b31 drives the moving plate 3012 to move, or the first straight tooth 301221 and the third straight tooth 301241 drive the moving plate 3012 to move.

[0078] Reference Figure 1 A protrusion 30125 is installed on the end of the movable plate 3012 away from the fixed mechanism 2. The protrusion 30125 has bolt holes that run vertically through it to limit the movable plate 3012 and the receiving groove 3013, thereby fixing the movable plate 3012 and the movable shell 3011 relative to each other.

[0079] Reference Figure 2 and Figure 7The fixing member 2012 has a fixing rod 2014 installed inside, connecting the front and rear ends of the fixing member 2012. The fixing rod 2014 is a hollow structure, and a stamping seat 2022 is sleeved inside the fixing rod 2014. The stamping seat 2022 and the fixing rod 2014 are coaxially arranged. The two ends of the fixing rod 2014 are connected to the fixing member 2012, so that the stamping part 202 is installed on the fixing member 2012.

[0080] Reference Figure 1 and Figure 6 The fixing part 201 has two pairs of opposing threaded holes on its left and right sides. One pair of threaded holes fixes the fixing rod 2014, and the other pair of threaded holes fixes the stamping seat 2022 inside the fixing rod 2014, so that the fixing rod 2014, the stamping seat 2022 and the stamping rod 2021 are coaxially fixed.

[0081] Reference Figure 4 The first sliding rod assembly 20132a and the second sliding rod assembly 20132b further include a ninth spring 20132a9 and an eighth spring 20132b9. The ninth spring 20132a9 and the eighth spring 20132b9 are respectively installed inside the first spring limiting frame 20132a5 and the second spring limiting frame 20132b5. The first spring limiting frame 20132a5 and the second spring limiting frame 20132b5 are respectively installed at the lower end of the first limiting plate 20132a3 and the second limiting plate 20132b3. After pressing the pressure plate clockwise downwards, the first sliding rod group 20132a and the second sliding rod assembly 20132b can be restored to their original state by the ninth spring 20132a9 and the eighth spring 20132b9, keeping the first sliding rod group 20132a and the second sliding rod assembly 20132b engaged with the moving plate 3012. The ninth spring 20132a9 and the eighth spring 20132b9 are kept in a compressed state, increasing the meshing force.

[0082] Reference Figure 3 and Figure 5 A portion of the first sliding vertical rod 20132a2 and a portion of the first limiting plate 20132a3 are located within the first trigger 20112. A portion of the second sliding vertical rod 20132b2 and a portion of the second limiting plate 20132b3 are located within the second trigger 20113, so that pulling the first trigger 20112 and the second trigger 20113 causes the first sliding vertical rod 20132a2 and the second sliding vertical rod 20132b2 to slide.

[0083] Reference Figure 1The front of the first trigger 20112 is grooved, and the rear of the first trigger 20112 is flat; the front of the second trigger 20113 is grooved, and the rear of the second trigger 20113 is flat. The first trigger 20112 has a first cavity communicating with the outside in the vertical direction; the second trigger 20113 has a second cavity communicating with the outside in the vertical direction.

[0084] The top horizontal cross-section of the first cavity is a first rectangular hole, and the bottom of the first cavity has a first limiting rod hole; the top horizontal cross-section of the second cavity is a second rectangular hole, and the bottom of the second cavity has a second limiting rod hole. The first sliding vertical rod 20132a2 passes through the first limiting rod hole 20132a7 and connects to the first sliding horizontal rod 20132a1. The first sliding vertical rod 20132a2 passes through the first limiting plate 20132a3 and penetrates the first rectangular hole 20132a6 to engage with the first rack 30122 and the third rack 30124. The second sliding vertical rod 20132b2 passes through the second limiting rod hole 20132b7 and connects to the second sliding horizontal rod 20132b1. The second sliding vertical rod 20132b2 passes through the second limiting plate 20132b3 and penetrates the second rectangular hole 20132b6 to engage with the second rack 30123. This design ensures that the first trigger 20112 and the second trigger 20113 do not interfere with each other when they move.

[0085] Reference Figure 3 Two first slide rods 20132a8 are mounted at the rear of the first trigger 20112. The other end of each slide rod 20132a8 abuts against one end of a sixth spring 20132a4, which in turn abuts against the handheld component 2011. Two second slide rods 20132b8 are mounted at the rear of the second trigger 20113. The other end of each slide rod 20132b8 abuts against one end of a seventh spring 20132b4, which in turn abuts against the handheld component 2011. Two holes are formed at the bottom of the first trigger 20112, through which the second slide rods 20132b8 pass and abut against the seventh spring 20132b4. The sixth spring 20132a4 and the seventh spring 20132b4 help the first and second slide rods 20132a8 and 20132b8 return to their original positions, preparing for the next sliding motion.

[0086] Reference Figure 5 A through hole is provided at the lower end of the fixing part 201 along the length direction of the moving plate 3012, allowing the moving plate 3012 to pass through and move.

[0087] Multiple vertical lines are engraved on plate 30121. When the vertical line closest to the vertical fixing member 2012 is aligned with the vertical boundary line of the fixing member 2012, the stamping rod 2021, the rubber barrier, and the receiving part 302 are in contact. If the first trigger 20112 is pressed, the end of the first stamping rod 20211 punches the smallest hole. If the second trigger 20113 is pressed, after the end of the first stamping rod 20211 punches the smallest hole, the second stamping rod 20212 punches the second smallest hole, and so on. Of course, it is not necessary to align the fixing member 2012 with the outermost vertical line during operation, as long as it is ensured that after punching the required hole, the remaining end of the stamping rod does not interact with the receiving part 302. If only the smallest hole is required, after the first punch rod 20211 exerts force on the receiving part 302, there is a gap between the end of the receiving part 302 and the second punch rod 20212, and the second punch rod 20212 fails to punch the corresponding hole. This operation is carried out according to the remaining vertical position, which increases the convenience and accuracy of punching.
