Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly, to a dental chair integrated with a laser therapy device. Background Art

[0002] As the core equipment for oral diagnosis and treatment, dental chairs have gradually integrated functional components such as water and gas supply systems, instrument trays, shadowless lamps, and digital control modules to meet diverse clinical needs. However, with the popularization of laser technology in dental surgeries (such as hemostasis, sterilization, painless tissue cutting, etc.), the limitations of existing dental chairs are gradually emerging: Inefficiency caused by equipment separation: Currently, laser therapy devices are generally placed beside dental chairs as independent equipment, occupying the diagnosis and treatment space and requiring frequent movement. When doctors switch between traditional dental chairs and laser devices, the operation process is forced to interrupt, especially in complex surgeries, which is likely to lead to an extended treatment time.

[0003] Redundant human-machine interaction: Laser therapy devices usually require a separate foot switch. When coexisting with the original foot switch of the dental chair, doctors need to repeatedly adjust their foot positions to control different devices, which not only increases the operation load but also poses a risk of accidental touch (a industry report "2023 Ergonomic Analysis of Dental Equipment" shows that the accidental operation rate of doctors in multi-foot-switch scenarios is as high as 12%).

[0004] System redundancy and cost disadvantage: Independent laser therapy devices need to be equipped with independent power supplies and water and gas circulation systems, resulting in large device volumes and high manufacturing costs.

[0005] Although there have been attempts to combine laser modules with dental chairs, their solutions have significant defects: Functional fragmentation: The laser module only exists in an external form, without achieving deep integration of the power supply and water and gas systems, and still relies on external pipeline connections; Rigid control: The foot switch lacks an intelligent switching mechanism and cannot automatically associate control paths according to the status of instrument access. Summary of the Invention

[0016] 2. Through the mutual cooperation of the two clamping plates, when the two pedals are stepped on simultaneously, the two clamping plates abut against each other, so that the positions of the two pedals can be locked to prevent the two pedals from being stepped on simultaneously; when a single pedal is stepped on, the corresponding clamping plate can move to the lower part of the adjacent clamping plate through the L-shaped guiding groove, so as to lock the position of the adjacent pedal, thereby ensuring that only a single pedal can be stepped on, improving the surgical safety.

[0017] 3. Through the cooperation of the driving motor, the rotating disk and the pressure ring, when the value of the pressure sensor fluctuates within a small range or the value does not change for a long time, the pressure sensor causes the driving motor to rotate, so that the rotating disk makes intermittent reciprocating rotations, making the avoidance hole and the corresponding conical guiding hole stagger. The rotating disk can intermittently block the conical guiding hole. In the blocking state, the sliding disk is in a completely sealed state, so that the position of the sliding disk can be locked, reducing the pressure on the doctor's feet and avoiding doctor fatigue.

Detailed implementation manners

[0020] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0022] In Embodiment 1, a laser therapy instrument main unit 21 is arranged inside the side box 2 (as Figure 1 shown), and the laser therapy instrument main unit 21 is an in-built type; the light guide arm 22 is arranged on the top of the side box 2 and communicates with the laser therapy instrument main unit 21. The position of the laser handpiece 24 can be adjusted through the light guide arm 22, and the laser handpiece 24 can hover through the light guide arm 22; secondly, by integrating the laser therapy instrument main unit 21 on the dental chair base 1, it becomes an important part of the dental chair base 1, which is convenient for dentists to use at any time. When the laser handpiece 24 is picked up, the circuit path part of the foot switch 5 is automatically connected to the laser therapy instrument signal through the changeover switch, so that when the doctor is performing treatment, the cooling water path and the water and mist path can be correspondingly switched on and off through the foot switch 5, which is convenient for dentists to control water and gas with their feet. This avoids the interruption of the operation process when the doctor switches between a traditional dental chair and a laser device, resulting in an extended treatment time.

[0023] Embodiment 2, see Figures 1 to 11As shown in the figure, a dental chair integrated with a laser treatment instrument includes a dental chair base 1, a side box 2, an instrument tray 3, a touch screen 4, and a foot switch 5; the side box 2 is arranged on the side of the dental chair base 1, and a laser treatment instrument main unit 21 is integrated outside the side box 2. The laser treatment instrument main unit 21 is connected to a laser handpiece 24 through an umbilical cord 23; a power supply circuit, a control circuit, a cooling water path, and a water mist path are integrated in the light guide arm 22 or the umbilical cord 23; the laser treatment instrument main unit 21 shares a power supply and a water and gas supply system with the dental chair; the instrument tray 3 is connected to the side box 2 through a joint arm, and the touch screen 4 is arranged at the upper rear part of the instrument tray 3 for adjusting laser treatment parameters; the on-off of the laser handpiece 24 is controlled by the foot switch 5, and the foot switch 5 supports sharing with the dental chair foot pedal and automatically switches the control path through a changeover switch.

[0024] In Embodiment 2, the laser treatment instrument main unit 21 is arranged side by side outside the side box 2 (as Figure 2 shown), and the laser treatment instrument main unit 21 is of a side-by-side type; the laser treatment instrument main unit 21 is "soft" connected to the laser handpiece 24 placed on the instrument tray 3 through the umbilical cord 23, and a dental and oral doctor can hold the laser handpiece 24 by hand, so that the position of the laser handpiece 24 can be adjusted better.

[0025] Embodiment 3, on the basis of Embodiment 1 or Embodiment 2, as shown in Figures 3 to 5 the figure, the foot switch 5 includes a bottom plate 51, a pedal 52, and a single-acting mechanism 53; there are two pedals 52, and the corresponding ends of the two pedals 52 are respectively hinged to one end of the top of the bottom plate 51. A vertical bar 511 is further arranged on the bottom plate 51, and the vertical bar 511 is located between the two pedals 52. A through groove 5111 is arranged at the top of the vertical bar 511, and both ends of the through groove 5111 face the corresponding pedal 52. Two L-shaped guiding grooves 5112 passing through the through groove 5111 are arranged in a mirror image on one side of the vertical bar 511; the single-acting mechanism 53 is arranged in the corresponding through groove 5111 and can lock the position of the other pedal 52 when any one of the pedals 52 moves; the single-acting mechanism 53 includes two clamping plates 531 arranged horizontally and capable of moving along the track of the corresponding L-shaped guiding groove 5112. A limiting plate 5113 matched with the clamping plate 531 is arranged at the top of the vertical bar 511, and a positioning plate 521 is further arranged on each pedal 52, and the positioning plate 521 is located between the corresponding clamping plate 531 and the limiting plate 5113; two sliding cylinders 512 are respectively hinged on each bottom plate 51, the opening ends of the sliding cylinders 512 face away from the bottom plate 51, a sliding disk 5121 is slidably arranged in each sliding cylinder 512, a guiding rod 5122 is arranged at the center of each sliding disk 5121, and one end of each guiding rod 5122 away from the sliding disk 5121 is hinged to the side of the corresponding pedal 52 close to the bottom plate 51. A return spring 5123 is further arranged in each sliding cylinder 512, and the return spring 5123 is located between the corresponding sliding disk 5121 and the inner wall of the bottom of the sliding cylinder 512.

[0026] To facilitate the doctor's control of the cooling water path and the water mist path, so that the two pedals 52 are respectively used to control the cooling water path and the water mist path. To avoid accidentally touching the two foot pedals simultaneously during stepping, which may cause the cooling water path and the water mist path to open at the same time. By providing a single-action mechanism 53 on the vertical strip 511 of the bottom plate 51, the single-action mechanism 53 includes two positioning plates 531 arranged horizontally and capable of moving along the trajectory of the corresponding L-shaped guiding groove 5112. In the initial state of the pedals 52, due to the elastic force of the return spring 5123, the positioning plates 521 on the two pedals 52 can be in contact with the limiting plates 5113 on the vertical strip 511, and the positioning plates 521 are located between the corresponding limiting plates 5113 and the positioning plates 531. When the two pedals 52 are stepped on simultaneously, the pedals 52 come into contact with the corresponding positioning plates 531, and the ends of the two positioning plates 531 are in contact with each other, so that the positions of the two positioning plates 531 can be restricted, and the positioning plates 531 can only move in the vertical direction. At this time, the two positioning plates 531 are mutually locked, and further the two pedals 52 cannot be stepped on simultaneously. When a single pedal 52 is stepped on, the stepped-on pedal 52 comes into contact with the corresponding positioning plate 531, thereby driving the corresponding positioning plate 531 to move along the trajectory of the L-shaped guiding groove 5112, so that the positioning plate 531 can move below the adjacent positioning plate 531, thereby locking the position of the adjacent positioning plate 531. When a single pedal 52 is stepped on, the adjacent pedal 52 is in a locked state, avoiding accidental touch and further ensuring the safety of use.

[0027] See Figures 5 to 7 As shown, the single-action mechanism 53 further includes a top spring 532 and an electric push rod 533; moving blocks 5311 are provided on both sides of each positioning plate 531 along the length direction, and the moving blocks 5311 can be slidably arranged in the corresponding L-shaped guiding groove 5112. A top spring 532 is mirror-symmetrically arranged at the bottom of each positioning plate 531. Mounting plates 5114 are provided at both ends of the through groove 5111, and an electric push rod 533 is provided on each mounting plate 5114. A clamping block 5331 is provided at one end of each electric push rod 533 facing the center of the through groove 5111, and a clamping groove 5312 cooperating with the clamping block 5331 is provided at the bottom of each positioning plate 531.

[0028] By providing an upper spring 532, the clamping plate 531 can be located at the upper end of the corresponding L-shaped guiding groove 5112. At this time, the ends of the two clamping plates 531 abut against each other. When the two clamping plates 531 are stepped on simultaneously, the two clamping plates 531 move simultaneously. When the two clamping plates 531 move to the corner of the L-shaped guiding groove 5112, since the ends of the two clamping plates 531 abut against each other, they cannot continue to move along the L-shaped guiding groove 5112, thus preventing the two pedals 52 from being stepped on simultaneously. When a single pedal 52 is stepped on, the clamping plate 531 moves towards the corresponding electric push rod 533. The clamping block 5331 on the electric push rod 533 can contact the clamping groove 5312 on the corresponding clamping plate 531. At this time, the electric push rod 533 drives the corresponding clamping plate 531 to move towards the center of the through groove 5111, so that the clamping plate 531 retracts into the through groove 5111. While ensuring that the stepped-on pedal 52 can continue to move downward, the clamping plate 531 moves along the corresponding L-shaped guiding groove 5112 to the lower side of the adjacent clamping plate 531, thereby locking the position of the adjacent pedal 52 and preventing it from being stepped on.

[0029] See Figures 8 to 11 As shown, a sealing ring 5124 is also provided at the open end of each sliding cylinder 512. The guide rod 5122 is slidably arranged inside the sealing ring 5124. The sliding cylinder 512 is filled with a buffer liquid 5125. Two conical guiding holes 5126 are mirror-symmetrically arranged on the sliding plate 5121.

[0030] To prevent the doctor from stepping on too fast, which may cause the flow rates of the cooling water path and the water mist path to be too fast and affect the surgical process; by filling the buffer liquid 5125 inside the sliding cylinder 512, under the elastic force of the return spring 5123, the pedal 52 abuts against the sealing ring 5124 at the open end of the sliding cylinder 512. At this time, the buffer liquid 5125 is located between the sliding plate 5121 and the inner wall of the bottom of the sliding cylinder 512. When the pedal 52 is stepped on, the pedal 52 drives the corresponding sliding plate 5121 to move through the guide rod 5122. At this time, since the sliding cylinder 512 is filled with the buffer liquid 5125 and the sliding plate 5121 is in sliding seal with the inner wall of the sliding cylinder 512, the buffer liquid 5125 can only move through the conical guiding holes 5126 on the sliding plate 5121. And the larger-diameter end of the conical guiding hole 5126 faces the bottom of the corresponding sliding cylinder 512. Thus, during the movement of the sliding plate 5121, when the buffer liquid 5125 flows through the conical guiding holes 5126, it can generate a resistance in the opposite direction to the movement of the sliding plate 5121, thereby preventing the movement speed of the sliding plate 5121 from being too fast and affecting the surgical operation. See Figures 8 to 11As shown in the figure, each sliding disk 5121 is also provided with a locking mechanism 54 capable of locking the position of the sliding disk 5121; each set of locking mechanisms 54 includes a driving motor 541, a rotating disk 542 and a pressure ring 543; a motor chamber 5127 is arranged at the center inside the sliding disk 5121, the driving motor 541 is arranged in the motor chamber 5127, the motor shaft of the driving motor 541 extends out of the motor chamber 5127 and is provided with a rotating disk 542, and an avoidance hole 5421 for avoiding the conical guiding hole 5126 is arranged on the rotating disk 542; a wiring groove 5128 communicating with the motor chamber 5127 is arranged inside the guiding rod 5122, the pressure ring 543 is coaxially arranged with the sliding disk 5121 and abuts against the corresponding return spring 5123, the pressure ring 543 and the sliding disk 5121 are connected to each other through two pressure sensors 544, and arc-shaped avoidance grooves 5422 for avoiding the pressure sensors 544 are arranged on the rotating disk 542 in a mirror image manner.

[0031] In some cases, it is necessary for the pedal 52 to stay at a fixed angle for a period of time, and it is necessary for the doctor to continuously apply pressure to the foot pedal. Under long-term stepping, the doctor will get tired; based on this situation, by arranging a motor chamber 5127 inside the sliding disk 5121, a driving motor 541 is arranged in the motor chamber 5127, the motor shaft of the driving motor 541 passes through the sliding disk 5121 and is provided with a rotating disk 542, and the pressure sensor 544 is electrically connected to the driving motor 541 through a processor (not shown in the figure). Under normal stepping conditions, the pressure ring 543 squeezes the return spring 5123, so that the value of the pressure sensor 544 changes accordingly. When the value of the pressure sensor 544 fluctuates within a small range or does not change for a long time, the pressure sensor 544 makes the driving motor 541 rotate, so that the rotating disk 542 makes intermittent reciprocating rotations, and the avoidance hole 5421 intersects with the corresponding conical guiding hole 5126. The rotating disk 542 can intermittently block the conical guiding hole 5126. In the blocked state, the sliding disk 5121 is in a completely sealed state, so that the position of the sliding disk 5121 can be locked, reducing the pressure on the doctor's foot and avoiding doctor fatigue.

[0032] See Figure 3 As shown in the figure, a protective shell 513 is also arranged on the bottom plate 51.

[0033] By arranging the protective shell 513, the equipment arranged on the bottom plate 51 can be protected to avoid being damaged due to accidental stepping.

[0034] See Figure 3 As shown in the figure, anti-slip patterns 522 are also arranged on the pedal 52.

[0035] By providing anti-slip lines 522, it is possible for doctors to step on the pedal 52 more conveniently, reducing the risk of the foot separating from the pedal 52 during the operation.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
