A dental endoscope for clinical use in dentistry

Abstract

This invention provides a dental endoscope specifically for clinical use in dentistry, belonging to the field of medical devices. It includes a grip rod, a mirror frame at the top of the grip rod, and a dental endoscope body fixedly connected to the inner wall of the mirror frame. The grip rod has a position adjustment component for adjusting the orientation of the dental endoscope body and an angle adjustment component for adjusting the angle of the dental endoscope body. Pushing a push block causes a first rack plate to slide, the first rack plate drives a first gear to rotate, the first gear drives a rotating rod to rotate, and the rotating rod drives the mirror frame and the dental endoscope body to rotate. When the dental endoscope body is rotated to an angle suitable for observing the patient's oral cavity, releasing the handle causes a first spring to return, a slider to drive a connecting plate, and the connecting plate to drive a pin to insert into a slot, thus restricting the first rack plate. Combined with the angle adjustment components, this allows for multi-directional examination of the patient's oral cavity, providing a more comprehensive understanding of the patient's oral health.

Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a dental endoscope for clinical use in dentistry. Background Technology

[0002] With the advancement of medical technology and the refinement of oral treatment, the dental endoscope, as a high-precision, high-magnification optical instrument, has become an important tool for clinical diagnosis and treatment in dentistry. It is widely used in many fields such as root canal treatment, dental implants, and dental restoration, significantly improving diagnostic accuracy and treatment effectiveness.

[0003] The existing dental endoscopes used in clinical settings have limitations during use. Due to the complex structure inside the patient's mouth, different lesions may be located in different positions and directions. As a result, staff may not only be unable to fully capture the detailed condition of the lesions inside the patient's mouth, but may also miss important diagnostic clues due to the limited field of vision. This reduces the practicality and efficiency of the existing devices. Summary of the Invention

[0004] In view of the problems existing in the prior art, which not only cannot fully capture the detailed situation of lesions in the patient's oral cavity, but may also miss important diagnostic clues due to limited field of vision, thus reducing the practicality and work efficiency of the device, the purpose of the present invention is to provide a dental endoscope for clinical use in dentistry.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A dental endoscope for clinical use includes a grip rod, a mirror frame at the top of the grip rod, an endoscope body fixedly connected to the inner wall of the mirror frame, an orientation adjustment component for adjusting the orientation of the endoscope body, and an angle adjustment component for adjusting the angle of the endoscope body.

[0007] Optionally, the orientation adjustment assembly includes a rotating rod rotatably connected to the middle of the grip rod. A first gear is fixedly connected to the bottom end of the rotating rod. A fixed frame is fixedly connected to the outer surface of the grip rod. A first rack plate is slidably connected to the middle of the fixed frame. The first rack plate slidably passes through the fixed frame, the grip rod, and the rotating rod. The first rack plate meshes with the first gear. A push block is fixedly connected to the front end of the first rack plate. A limiting component for restricting the first rack plate is provided on the fixed frame.

[0008] Optionally, the limiting component includes a rectangular sleeve fixedly connected to the top of the fixed frame. A slider is slidably connected to the inner wall of the rectangular sleeve.

[0009] Optionally, the angle adjustment assembly includes two arc-shaped plates, which are fixedly connected to the top of the rotating rod. A rotating shaft is rotatably connected between the two arc-shaped plates. The mirror frame is fixedly connected to the rotating shaft. A second gear is fixedly connected to the outer surface of the rotating shaft. A rectangular groove is formed in the middle of the rotating rod. A connecting rod is slidably connected to the inner wall of the rectangular groove. A second rack plate is fixedly connected to the top of the connecting rod. The second rack plate meshes with the second gear. A push rod is fixedly connected to the bottom of the connecting rod. The push rod slides through one end of the connecting plate. A round block is fixedly connected to the end of the push rod away from the connecting rod. An arc-shaped opening is formed on the gripping rod. The push rod slides through the arc-shaped opening. A fixing component is provided on the push rod.

[0010] Optionally, the fixing component includes a rectangular shell slidably connected to the outer surface of the push rod, a movable block slidably connected to the inner wall of the rectangular shell, a second spring fixedly connected between the rectangular shell and the movable block, a pushing block fixedly connected to the front end of the movable block, the pushing block slidably passing through the front end of the rectangular shell, an insert rod fixedly connected to the top end of the movable block, the insert rod slidably passing through the upper end of the rectangular shell, a plurality of insertion holes that cooperate with the insert rod are provided on the push rod, and an arc plate is fixedly connected to the outer surface of the gripping rod, with a plurality of insertion ports provided at the lower end of the arc plate.

[0011] Optionally, a circular tube is fixedly connected to the middle of the oral endoscope, and multiple liquid outlet tubes are fixedly connected to the outer surface of the circular tube. The multiple liquid outlet tubes pass through the inner side of the endoscope frame. A flexible tube is fixedly connected to the outer surface of the circular tube and passes through the outer side of the endoscope frame. A liquid bladder is fixedly connected inside the gripping rod. The end of the flexible tube away from the circular tube is fixedly connected to the liquid bladder. A release component is provided on the liquid outlet tube, and a squeezing component for squeezing the liquid bladder is provided on the gripping rod.

[0012] Optionally, the release assembly includes a frustum, which is fixedly connected inside the liquid outlet pipe. The frustum has a liquid outlet, and a sealing ball is engaged inside the liquid outlet. Two elastic ropes are fixedly connected between the inner wall of the liquid outlet pipe and the sealing ball.

[0013] Optionally, the extrusion assembly includes an extrusion plate fixedly connected to the outer surface of the liquid bladder. A hollow rod is fixedly connected to the liquid bladder, penetrating the extrusion plate. A rectangular block is fixedly connected to the side of the hollow rod away from the liquid bladder. A liquid inlet hole is provided on the rectangular block, and the liquid inlet hole communicates with the inner wall of the hollow rod. A sealing plate is rotatably connected to the inner wall of the hollow rod, and a rotating block is fixedly connected to the top of the sealing plate.

[0014] Optionally, a plurality of lighting lamps are fixedly connected to the front end of the frame, and the plurality of lighting lamps are arranged in a circle.

[0015] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0016] In the above scheme, by setting a first gear and a first rack plate, when it is necessary to adjust the position of the oral endoscope, the restriction on the first rack plate is first released. Then, the push block is pushed, which causes the first rack plate to slide within the fixed frame and the rotating rod. The first rack plate drives the first gear to rotate, which in turn drives the rotating rod to rotate. The rotating rod then drives the endoscope frame and the oral endoscope to rotate. When the oral endoscope is rotated to an angle that is convenient for observing the patient's oral cavity, the handle is released, the first spring rebounds, the slider drives the connecting plate, and the connecting plate drives the pin to insert into the slot on the first rack plate, thus restricting the first rack plate. In conjunction with the angle adjustment component, the patient's oral cavity can be examined from multiple angles, thereby gaining a more comprehensive understanding of the patient's oral health status.

[0017] With a second gear and a second rack plate, when the angle of the oral endoscope needs to be adjusted, the restriction on the push rod is first released. Then, the circular block is pushed, causing the push rod and connecting rod to slide within the rectangular groove. The connecting rod causes the second rack plate to slide, which in turn drives the second gear to rotate. The second gear then drives the rotating shaft to rotate, which in turn drives the oral endoscope to rotate, thus adjusting the angle of the oral endoscope. When the oral endoscope is adjusted to an angle that facilitates observation of the patient's oral cavity, the push block is released, the second spring returns, and the moving block causes the insertion rod to pass through the insertion hole and insert into the slot on the arc plate, thus restricting the push rod. This allows for easier adaptation to the observation needs of different areas and angles within the patient's oral cavity, enabling staff to observe the details inside the patient's oral cavity more clearly.

[0018] Equipped with a circular tube and an outlet tube, when it is necessary to clean oral mucus and impurities adhering to the surface of the oral endoscope, the cleaning solution is added into the hollow rod through the inlet hole on the rectangular block. The solution then enters the liquid sac through the hollow rod. After addition, the rotating block is turned, which moves the sealing plate to seal the hollow rod. Then, the rectangular block is pushed, which moves the hollow rod. The hollow rod moves the squeezing plate to squeeze the cleaning solution in the liquid sac, allowing the cleaning solution to clean the oral mucus and impurities adhering to the surface of the oral endoscope. This prevents oral mucus and impurities on the surface of the oral endoscope from obstructing or blurring the field of vision, thus affecting the staff's observation of the patient's oral cavity.

[0019] Equipped with a truncated cone and a sealing ball, when the cooling solution needs to be released, the squeezing assembly is pushed to compress the liquid bladder, creating pressure that allows the cleaning solution to quickly enter the tubing. The cleaning solution in the tubing then flows through the annular tube into the outlet tube. Under the pressure of the squeezed liquid bladder, the cleaning solution pushes the sealing ball open from the outlet on the truncated cone. The elastic cord stretches, and as the sealing ball is pushed open, the cleaning solution flows out through the gap between the outlet and the sealing ball, facilitating the cleaning of oral mucus and impurities adhering to the surface of the oral endoscope. After the cleaning solution has flowed out, the elastic cord rebounds, causing the sealing ball to engage with the outlet, sealing the outlet on the truncated cone and thus improving the patient's intraoral visual field.

[0041] like Figures 1 to 12As shown, this embodiment of the invention provides a dental endoscope for clinical use in dentistry, including a grip rod 101. A mirror frame 102 is provided at the top of the grip rod 101, and a dental endoscope body 103 is fixedly connected to the inner wall of the mirror frame 102. The grip rod 101 is provided with a position adjustment component for adjusting the position of the dental endoscope body 103, and an angle adjustment component is provided on the grip rod 101 for adjusting the angle of the dental endoscope body 103.

[0042] The staff member holds the handle 101 and places the oral endoscope 103 inside the patient's mouth for observation. Then, the staff member adjusts the oral endoscope 103 by adjusting the orientation adjustment component to a position suitable for the staff member to observe the patient's mouth. The staff member adjusts the angle between the handle 101 and the oral endoscope 103 by adjusting the angle adjustment component to a position that facilitates the staff member's observation of the patient's mouth, thereby improving the staff member's observation of the patient's mouth.

[0043] like Figure 2 and Figure 3 As shown, the orientation adjustment assembly includes a rotating rod 201, which is rotatably connected to the middle of the grip rod 101. A first gear 202 is fixedly connected to the bottom end of the rotating rod 201. A fixing frame 203 is fixedly connected to the outer surface of the grip rod 101. A first rack plate 204 is slidably connected to the middle of the fixing frame 203. The first rack plate 204 slidably passes through the fixing frame 203, the grip rod 101, and the rotating rod 201. The first rack plate 204 meshes with the first gear 202. A push block 205 is fixedly connected to the front end of the first rack plate 204. A limiting component for restricting the first rack plate 204 is provided on the fixing frame 203.

[0044] When the orientation of the oral endoscope 103 needs to be adjusted, the push block 205 is pushed. The push block 205 causes the first rack plate 204 to slide within the fixed frame 203 and the rotating rod 201. The first rack plate 204 drives the first gear 202 to rotate. The first gear 202 drives the rotating rod 201 to rotate. The rotating rod 201 drives the endoscope frame 102 and the oral endoscope 103 to rotate. When the oral endoscope 103 is rotated to an angle that is convenient for observing the patient's oral cavity, the first rack plate 204 is restricted by the limiting component, which makes it convenient for staff to examine the patient's oral cavity from multiple angles, thereby gaining a more comprehensive understanding of the patient's oral health status.

[0045] like Figure 4As shown, the limiting component includes a rectangular sleeve 206, which is fixedly connected to the top of the fixed frame 203. A slider 207 is slidably connected to the inner wall of the rectangular sleeve 206. A handle 208 is fixedly connected to one side of the slider 207 and slides through one side of the rectangular sleeve 206. A first spring 209 is fixedly connected between the inner wall of the rectangular sleeve 206 and the slider 207. A connecting plate 210 is fixedly connected to the front end of the slider 207 and slides through the front end of the rectangular sleeve 206. A pin 211 is fixedly connected to the bottom end of the connecting plate 210 and slides through the lower end of the rectangular sleeve 206 and the upper end of the fixed frame 203. A plurality of slots 212 that cooperate with the pins 211 are provided on the first rack plate 204.

[0046] When it is necessary to restrict the first rack plate 204, pull the handle 208 upward. The handle 208 drives the slider 207 to slide within the rectangular sleeve 206. The first spring 209 is compressed, and the slider 207 drives the connecting plate 210 to move upward. The connecting plate 210 drives the pin 211 to leave the slot 212. Then, adjust the orientation adjustment component. When the oral endoscope 103 is adjusted to a suitable angle, release the handle 208. The first spring 209 rebounds, and the slider 207 drives the connecting plate 210. The connecting plate 210 drives the pin 211 to insert into the slot 212 on the first rack plate 204, preventing the first rack plate 204 from sliding arbitrarily and affecting the orientation adjustment of the oral endoscope 103.

[0047] like Figures 5 to 8 As shown, the angle adjustment assembly includes two arc-shaped plates 213, which are fixedly connected to the top of the rotating rod 201. A rotating shaft 214 is rotatably connected between the two arc-shaped plates 213. The mirror frame 102 is fixedly connected to the rotating shaft 214. A second gear 215 is fixedly connected to the outer surface of the rotating shaft 214. A rectangular groove 216 is formed in the middle of the rotating rod 201. A connecting rod 217 is slidably connected to the inner wall of the rectangular groove 216. A second rack plate 218 is fixedly connected to the top of the 7, and the second rack plate 218 meshes with the second gear 215. A push rod 219 is fixedly connected to the bottom of the connecting rod 217. The push rod 219 slides through one end of the connecting plate 210. A round block 220 is fixedly connected to the end of the push rod 219 away from the connecting rod 217. An arc-shaped opening 221 is opened on the gripping rod 101. The push rod 219 slides through the arc-shaped opening 221. A fixing component is provided on the push rod 219.

[0048] When the angle of the oral endoscope 103 needs to be adjusted, the circular block 220 is pushed. The circular block 220 drives the push rod 219 and the connecting rod 217 to slide within the rectangular groove 216. The connecting rod 217 drives the second rack plate 218 to slide. The second rack plate 218 drives the second gear 215 to rotate. The second gear 215 drives the rotating shaft 214 to rotate. The rotating shaft 214 drives the oral endoscope 103 to rotate, thus adjusting the angle of the oral endoscope 103. When the oral endoscope 103 is adjusted to an angle that is convenient for observing the patient's oral cavity, the push rod 219 is restricted by the fixing component. This facilitates the adaptation to the observation needs of different areas and angles inside the patient's oral cavity, allowing staff to observe the details inside the patient's oral cavity more clearly. By setting the arc-shaped opening 221, when the rotating rod 201 is rotating, the rotating rod 201 can drive the push rod 219 to slide within the arc-shaped opening 221, avoiding affecting the angle adjustment component's adjustment of the angle of the oral endoscope 103.

[0049] like Figure 9 As shown, the fixing assembly includes a rectangular shell 222, which is slidably connected to the outer surface of the push rod 219. A moving block 223 is slidably connected to the inner wall of the rectangular shell 222. A second spring 224 is fixedly connected between the rectangular shell 222 and the moving block 223. A pushing block 225 is fixedly connected to the front end of the moving block 223. The pushing block 225 slides through the front end of the rectangular shell 222. An insert rod 226 is fixedly connected to the top end of the moving block 223. The insert rod 226 slides through the upper end of the rectangular shell 222. The push rod 219 has multiple insertion holes 227 that cooperate with the insert rod 226. An arc plate 228 is fixedly connected to the outer surface of the gripping rod 101. Multiple insertion slots 229 are opened at the lower end of the arc plate 228.

[0050] When it is necessary to fix the push rod 219, push the push block 225. Push the push block 225 and drive the moving block 223 to slide within the rectangular shell 222. The second spring 224 is compressed. The moving block 223 drives the insertion rod 226 to leave the insertion port 229 and the insertion hole 227. Then, adjust the angle adjustment component. When the oral endoscope 103 is adjusted to a suitable angle, release the push block 225. The second spring 224 rebounds. The moving block 223 drives the insertion rod 226 to pass through the insertion hole 227 and insert into the insertion port 229 on the arc plate 228, thus restricting the push rod 219 and preventing it from sliding arbitrarily, which would affect the angle adjustment of the oral endoscope 103.

[0051] like Figure 10 and Figure 11As shown, a circular tube 230 is fixedly connected to the middle of the oral endoscope 103. Multiple liquid outlet tubes 231 are fixedly connected to the outer surface of the circular tube 230. The multiple liquid outlet tubes 231 pass through the inner side of the endoscope frame 102. A flexible tube 232 is fixedly connected to the outer surface of the circular tube 230. The flexible tube 232 passes through the outer side of the endoscope frame 102. A liquid bladder 233 is fixedly connected inside the grip rod 101. The end of the flexible tube 232 away from the circular tube 230 is fixedly connected to the liquid bladder 233. A release component is provided on the liquid outlet tube 231. A squeezing component for squeezing the liquid bladder 233 is provided on the grip rod 101.

[0052] When it is necessary to clean the oral mucus and impurities adhering to the surface of the oral endoscope 103, the squeezing component is pushed to squeeze the liquid bladder 233, so that the cleaning fluid in the liquid bladder 233 enters the annular tube 230 through the tubing 232, and then the cleaning fluid is released through the release component in the outlet tube 231, so that the cleaning fluid is released onto the surface of the oral endoscope 103 to clean the oral mucus and impurities adhering to the surface of the oral endoscope 103, so as to avoid the oral mucus and impurities on the surface of the oral endoscope 103 obstructing or blurring the field of vision and affecting the staff's observation of the inside of the patient's oral cavity.

[0053] like Figure 12 As shown, the release assembly includes a frustum 234, which is fixedly connected inside the liquid outlet pipe 231. The frustum 234 has a liquid outlet 235, and a sealing ball 236 is engaged inside the liquid outlet 235. Two elastic ropes 237 are fixedly connected between the inner wall of the liquid outlet pipe 231 and the sealing ball 236.

[0054] When the cooling fluid needs to be released, the squeezing assembly is pushed to squeeze the liquid bladder 233, causing the cleaning fluid to be pressurized and quickly enter the hose 232. The cleaning fluid in the hose 232 enters the outlet pipe 231 through the annular tube 230. Under the pressure of the squeezed liquid bladder 233, the cleaning fluid can push the sealing ball 236 out of the outlet 235 on the frustum 234. The elastic rope 237 is stretched. While the sealing ball 236 is pushed open, the cleaning fluid can flow out through the gap between the outlet 235 and the sealing ball 236, releasing the cleaning fluid. After the cleaning fluid has flowed out, the elastic rope 237 rebounds, causing the sealing ball 236 to engage with the outlet 235, sealing the outlet 235 on the frustum 234.

[0055] like Figure 11As shown, the extrusion assembly includes an extrusion plate 238, which is fixedly connected to the outer surface of the liquid bladder 233. A hollow rod 239 is fixedly connected to the liquid bladder 233, and the hollow rod 239 penetrates the extrusion plate 238. A rectangular block 240 is fixedly connected to the side of the hollow rod 239 away from the liquid bladder 233. A liquid inlet hole 241 is provided on the rectangular block 240, and the liquid inlet hole 241 communicates with the inner wall of the hollow rod 239. A sealing plate 242 is rotatably connected to the inner wall of the hollow rod 239, and a rotating block 243 is fixedly connected to the top of the sealing plate 242.

[0056] When the liquid bladder 233 needs to be squeezed, the rectangular block 240 is pushed, which drives the hollow rod 239 to move. The hollow rod 239 drives the squeezing plate 238 to squeeze the cleaning fluid in the liquid bladder 233, so that the cleaning fluid cleans the oral mucus and impurities attached to the surface of the oral endoscope 103. When the cleaning fluid needs to be added to the liquid bladder 233, the cleaning fluid is added to the hollow rod 239 through the liquid inlet hole 241 on the rectangular block 240. After the addition is completed, the rotating block 243 is turned, which drives the sealing plate 242 to seal the hollow rod 239 to prevent the cleaning fluid in the liquid bladder 233 from flowing out.

[0057] like Figure 1 As shown, a plurality of lighting lamps 244 are fixedly connected to the front end of the frame 102, and the plurality of lighting lamps 244 are arranged in a circle.

[0058] The presence of a lighting lamp 244 enhances the illumination of the patient's oral cavity for staff, thereby improving the accuracy of observation.

[0059] The workflow of the technical solution of this invention is as follows:

[0060] In use, the operator holds the handle 101 and places the oral endoscope 103 in the patient's mouth. Pulling the handle 208 upward causes the slider 207 to slide within the rectangular sleeve 206, compressing the first spring 209. The slider 207 then moves the connecting plate 210 upward, causing the pin 211 to disengage from the slot 212. Next, the pusher 205 is pushed to move the first rack plate 204 within the fixed frame 203 and the rotating rod 201. The first rack plate 204 drives the first gear 202 to rotate, which in turn drives the rotating rod 201 to rotate. The rotating rod 201 then drives the endoscope frame 102 and the oral endoscope 103 to rotate.

[0061] When the oral endoscope 103 is rotated to an angle that facilitates observation of the patient's oral cavity, the handle 208 is released, the first spring 209 rebounds, the slider 207 drives the connecting plate 210, and the connecting plate 210 drives the pin 211 to insert into the slot 212 on the first rack plate 204, thus restricting the first rack plate 204 and facilitating multi-directional examination of the patient's oral cavity by the staff. Then, the push block 225 is pushed, which drives the moving block 223 to slide within the rectangular shell 222. The second spring 224 is compressed, and the moving block 223 drives the insertion rod 226 to leave the insertion port 229 and the insertion hole 227. Then, the round block 220 is pushed, which drives the push rod 219 and the connecting rod 217 to slide within the rectangular groove 216. When the connecting rod 217 moves, it drives the second rack plate 218 to slide. The second rack plate 218 drives the second gear 215 to rotate. The second gear 215 drives the rotating shaft 214 to rotate. The rotating shaft 214 drives the oral endoscope 103 to rotate, adjusting the angle of the oral endoscope 103. When the oral endoscope 103 is adjusted to an angle that is convenient for observing the patient's oral cavity, the push block 225 is released, the second spring 224 rebounds, and the moving block 223 drives the insertion rod 226 to pass through the insertion hole 227 and insert into the insertion slot 229 on the arc plate 228, restricting the push rod 219. This makes it easier to adapt to the observation needs of different areas and angles inside the patient's oral cavity, allowing staff to observe the details inside the patient's oral cavity more clearly.

[0062] Then, multiple lights 244 on the frame 102 illuminate the patient's oral cavity, improving the staff's ability to observe lesions. When it is necessary to clean oral mucus and impurities adhering to the surface of the oral endoscope 103, the cleaning solution is added into the hollow rod 239 through the inlet hole 241 on the rectangular block 240. The solution then enters the liquid sac 233 through the hollow rod 239. After addition, the rotating block 243 is turned, causing the sealing plate 242 to seal the hollow rod 239. Then, the rectangular block 240 is pushed, causing the hollow rod 239 to move. The hollow rod 239 then causes the squeezing plate 238 to squeeze the cleaning solution in the liquid sac 233, creating pressure and quickly allowing the cleaning solution to enter the tubing 232. The cleaning fluid in the tubing 232 enters the outlet tube 231 through the annular tube 230. Under the pressure of the squeezed bladder 233, the cleaning fluid can push the sealing ball 236 out of the outlet 235 on the frustum 234. The elastic rope 237 is stretched. While the sealing ball 236 is pushed open, the cleaning fluid can flow out through the gap between the outlet 235 and the sealing ball 236, so that the cleaning fluid is released onto the surface of the oral endoscope 103 to clean the oral mucus and impurities adhering to the surface of the oral endoscope 103. The cleaning fluid in the patient's mouth can be discharged by the negative pressure device. After the cleaning fluid has flowed out, the elastic rope 237 rebounds, causing the sealing ball 236 to engage with the outlet 235, sealing the outlet 235 on the frustum 234.
