Description

Technical Field

[0001] This invention specifically relates to a device for cleaning a spinal cord plucking needle. Background Technology

[0002] During root canal treatment, a pulp pluck is used to remove the dental pulp inside the tooth, and then the pulp cavity is filled with filling material. Since the dental pulp contains loose connective tissue containing nerves and blood vessels, and is mostly located inside the pulp cavity of the tooth, the pulp pluck is usually barbed or spiral-shaped to facilitate better removal of the dental pulp. At the same time, this also causes the pulp pluck to become entangled with a lot of dental pulp tissue during the removal process. In order to avoid the dental pulp tissue entangled with the pulp pluck affecting the removal of the dental pulp, the dental pulp tissue entangled with the pulp pluck needs to be cleaned multiple times during the removal process.

[0003] For example, Chinese patent number 202021508471.0 discloses a cleaning device for the side of a pedicle screw fixation chair, including a cleaning box, a rotating box, a limiting groove, brushes, a rotating shaft, and a bearing seat. The cleaning device includes a cleaning box and a rotating box below it. A groove is provided on the lower plane of the cleaning box. One end of the rotating shaft is threaded into the groove, and the other end is fixed to the bearing seat on the top of the rotating box, and fixedly connected to a motor inside the rotating box. The limiting groove is located at the center of the top plane of the cleaning box, and the brushes are arranged in a cluster on the inner wall of the cleaning box.

[0004] Existing pulp apexification needle cleaning devices clean the needles by rotating the cleaning box, which in turn rotates the brushes inside. However, during the cleaning process, the pulp tissue on the needles tends to adhere to the brushes, and existing devices cannot remove the pulp tissue from the brushes. As the brushes rotate and remain in contact with the needles, the pulp tissue on the brushes tends to re-adhere to the needles, thus reducing the cleaning effectiveness of the device. Therefore, to address the above technical problems, a new pulp apexification needle cleaning device is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a pulp extraction needle cleaning device that facilitates the cleaning of pulp tissue attached to the brush, preventing the pulp tissue on the brush from re-attaching to the pulp extraction needle and improving the cleaning effect of the device.

[0006] A bone marrow plucking needle cleaning device, comprising:

[0007] The base has a cleaning chamber inside, and the top of the base has a positioning hole that is coaxial with and communicates with the cleaning chamber;

[0008] The brush mechanism includes multiple sets of brush rods and a drive assembly. The multiple sets of brush rods are arranged circumferentially around the cleaning chamber, and the axis of the brush rods is parallel to the axis of the cleaning chamber. The drive assembly connects the multiple sets of brush rods and the base, and is used to drive the multiple sets of brush rods to rotate around the axis of the cleaning chamber while rotating on their own axis.

[0009] The slag removal assembly includes a fixing ring and scrapers. The fixing ring is detachably disposed in the cleaning chamber and sleeved around the periphery of multiple sets of brush rods. Multiple sets of scrapers are arranged at intervals along the circumference of the inner side of the fixing ring. Each set of scrapers has multiple scraping grooves for the brushes on the brush rods to pass through.

[0010] The beneficial effects of the above-mentioned bone marrow plucking needle cleaning device are as follows:

[0011] During cleaning, the pulp plucking needle is inserted into the cleaning chamber through the positioning hole. At this time, the brushes on multiple sets of brush rods contact the periphery of the pulp plucking needle. Then, the drive assembly drives the multiple sets of brush rods to rotate around the axis of the cleaning chamber while simultaneously rotating on their own axis. The rotation of the multiple sets of brush rods around the axis of the cleaning chamber allows the brushes on the multiple sets of brush rods to rotate around the periphery of the pulp plucking needle, thereby removing the pulp tissue on the pulp plucking needle. At the same time, the rotation of the multiple sets of brush rods allows the brushes on the brush rods to pass through the scraping groove after contacting the pulp plucking needle. At this time, the scraping groove can remove the pulp tissue attached to the brush. After the pulp tissue on the brush is removed, it can contact the pulp plucking needle again to clean the pulp plucking needle. This makes it convenient to clean the pulp tissue attached to the brush and avoids the pulp tissue on the brush from re-attaching to the pulp plucking needle, thus improving the cleaning effect of the device.

[0012] In one embodiment, the driving assembly includes a turntable, a motor, a power supply, mounting rods, and an internal gear ring. The turntable is rotatably mounted on the bottom surface of the cleaning chamber. The motor and the power supply are electrically connected and both are mounted on the base. The motor output is connected to the turntable. Multiple mounting rods are rotatably mounted on the turntable corresponding to multiple sets of brush rods. Each set of mounting rods is equipped with a gear. The internal gear ring is located at the bottom of the cleaning chamber, and all gears mesh with the internal gear ring. Starting the motor drives the turntable to rotate, which in turn rotates the mounting rods, thus rotating the brush rods. Driving the brush rods to rotate around the cleaning chamber axis is convenient. Simultaneously, the rotation of the mounting rods causes the gears to rotate and mesh with the internal gear ring, causing the gears to rotate. This rotation of the gears drives the mounting rods to rotate, which in turn drives the brush rods to rotate, making the brush rod rotation convenient.

[0013] In one embodiment, a connecting hole is formed along the axis of the brush rod, through which the brush rod passes. The connecting hole is fitted onto the mounting rod, and a positioning block is provided around the connecting hole. A positioning groove is formed around the mounting rod, and the positioning block can be engaged within the positioning groove. The top end of the mounting rod extends outside the connecting hole and is detachably connected to a limiting plate. The brush rod can be removed from the mounting rod by removing the limiting plate, making the installation and removal of the brush rod convenient and facilitating its replacement.

[0014] In one embodiment, a flushing assembly is also included, which flushes the plucked needle within the cleaning cavity.

[0015] In one embodiment, the rinsing assembly includes a water pump; a storage chamber for storing disinfectant is formed in the side wall of the base, and an injection port communicating with the storage chamber is formed on the periphery of the base. A sealing cap is detachably provided on the injection port. The water pump is mounted on the base and electrically connected to a power source. The inlet pipe of the water pump communicates with the bottom of the storage chamber, and a diverter ring is provided on the outlet pipe of the water pump. The diverter ring is coaxially arranged with the cleaning chamber and located between the top of the cleaning chamber and the positioning hole. Multiple sets of outlets facing the axis of the cleaning chamber are spaced apart along the circumference of the cleaning chamber on the diverter ring. By activating the water pump, the water pump can draw out the disinfectant from the storage chamber and spray it onto the plucked needle through the outlets to rinse the needle, thereby further improving the cleaning effect on the plucked needle.

[0016] In one embodiment, a collection bottle is detachably connected to the lower end of the base, and multiple drainage ports communicating with the inner cavity of the collection bottle are provided on the bottom surface of the cleaning chamber. The collection bottle facilitates the collection of waste fluid generated after rinsing the raphe needle, preventing the raphe needle from being contaminated by soaking in the waste fluid.

[0017] In one embodiment, a filter screen cover is provided inside the collection bottle, a support ring is provided on the inner side wall of the collection bottle, and a boss is provided on the periphery of the filter screen cover, with the bottom end of the boss abutting the top end of the support ring. When the waste liquid generated after rinsing the pulp extraction needle flows into the collection bottle through the filter screen cover, the filter screen cover can filter out the pulp tissue in the waste liquid, thereby performing a solid-liquid separation operation, which facilitates the subsequent separate treatment of the pulp tissue and the waste liquid.

[0018] In one embodiment, the base is detachably topped with a top cover, the positioning hole being formed in the top cover, and a clamping assembly being provided on the top cover for fixing the plucked needle to the top cover. Removing the top cover facilitates cleaning of the inside of the device, and by using the clamping assembly to fix the plucked needle, it is not necessary to hold the needle during cleaning, making cleaning convenient.

[0019] In one embodiment, the clamping assembly includes two sets of clamping plates and an elastic element. Two sets of guide grooves are oppositely formed on the top cover. Each set of guide grooves contains a guide rod. Each set of clamping plates contains a guide block. The guide blocks are slidably disposed within the guide grooves along the positioning hole and are fitted onto the guide rods. The elastic element is fitted onto each guide rod. One end of the elastic element abuts against the end of the guide block away from the positioning hole, and the other end abuts against the end of the guide groove away from the positioning hole. When fixing the plucked needle, the clamping plates are first moved away from each other. This relative movement compresses the elastic element. Then, the tip of the plucked needle passes through the positioning hole, positioning the holding part between the two clamping plates. The force applied to the clamping plates is then released. The reaction force of the elastic element causes the clamping plates to move closer together, clamping the holding part of the plucked needle and thus fixing it to the top cover. This method of fixing the plucked needle is convenient.

[0020] In one embodiment, anti-slip pads are detachably provided on opposite sides of both sets of clamping plates. The anti-slip pads increase the friction between the clamping plates and the plucked needle, thereby improving the stability of the plucked needle fixation. Furthermore, the detachable nature of the anti-slip pads facilitates their replacement. Attached Figure Description

[0037] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0038] Please see Figure 1 , Figure 2 , Figure 4 One embodiment of a bone marrow plucking needle cleaning device includes a base 10, a brush mechanism 20, and a slag removal component 30.

[0039] The base 10 has a cleaning chamber 101 inside, and a positioning hole 102 coaxial with and communicating with the cleaning chamber 101 is formed at the top of the base 10. Specifically, a top cover 104 is detachably provided at the top of the base 10, the positioning hole 102 is formed on the top cover 104, and a clamping assembly 50 is provided on the top cover 104 for fixing the plucked needle to the top cover 104. In this embodiment, the top cover 104 and the base 10 are threadedly connected.

[0040] In the above embodiments, by providing a detachable top cover 104, it is convenient to clean the cleaning chamber 101 after removing the top cover 104. Furthermore, by providing a clamping component 50, the plucked needle can be fixed on the top cover 104. When cleaning the plucked needle, there is no need to hold the plucked needle, making it convenient to use.

[0041] Please refer to the following: Figure 6 Specifically, the clamping assembly 50 includes two sets of clamping plates 503 and elastic elements 501. Two sets of guide grooves 105 are oppositely formed on the top cover 104. Guide rods 106 are provided in each of the two sets of guide grooves 105. Guide blocks 502 are provided on each of the two sets of clamping plates 503. The two sets of guide blocks 502 are respectively slidably disposed within the two sets of guide grooves 105 along the positioning hole 102 and are sleeved on the guide rods 106. Elastic elements 501 are sleeved on each of the two sets of guide rods 106. One end of the elastic element 501 abuts against the end of the guide block 502 away from the positioning hole 102, and the other end abuts against the end of the guide groove 105 away from the positioning hole 102. Specifically, in this embodiment, the elastic element 501 is a spring.

[0042] In the above embodiment, when it is necessary to clamp the plucked bone needle, a force is applied to the two sets of clamping plates 503 to move the two sets of clamping plates 503 relatively away. The relative movement of the two sets of clamping plates 503 can squeeze the elastic member 501. Then, the tip of the plucked bone needle passes through the positioning hole 102 and the holding part is positioned between the two sets of clamping plates 503. Then, the force applied to the two sets of clamping plates 503 is released. At this time, the reaction force of the elastic member 501 causes the two sets of clamping plates 503 to move relatively closer. The relative movement of the two sets of clamping plates 503 can clamp the holding part of the plucked bone needle, thereby fixing the plucked bone needle on the top cover 104, which makes it convenient to fix the plucked bone needle.

[0043] Based on the above embodiments, further, anti-slip pads 505 are detachably provided on opposite sides of both sets of clamping plates 503. Specifically, in this embodiment, slots 504 are provided on opposite surfaces of both sets of clamping plates 503, and locking blocks 506 are provided on the anti-slip pads 505, which can be locked in the slots 504.

[0044] In the above embodiments, by setting the anti-slip pad 505, the friction between the clamping plate 503 and the plucked needle can be increased, thereby improving the stability of fixing the plucked needle. In addition, the anti-slip pad 505 and the clamping plate 503 are snap-fit ​​connected, which makes installation and disassembly convenient and facilitates the replacement of the anti-slip pad 505.

[0045] Please see Figures 2 to 5 In one embodiment, the brush mechanism 20 includes multiple sets of brush rods 205 and a drive assembly. The multiple sets of brush rods 205 are circumferentially spaced around the cleaning chamber 101, and the axes of the brush rods 205 are parallel to the axis of the cleaning chamber 101. The drive assembly connects the multiple sets of brush rods 205 and the base 10, and is used to drive the multiple sets of brush rods 205 to rotate around the axis of the cleaning chamber 101 while simultaneously rotating on their own axis. The slag removal assembly 30 includes a fixing ring 303 and scrapers 301. The fixing ring 303 is detachably disposed within the cleaning chamber 101 and sleeved around the periphery of the multiple sets of brush rods 205. Multiple sets of scrapers 301 are circumferentially spaced along the inner side of the fixing ring 303, and each set of scrapers 301 has multiple scraping grooves 302 for the brushes on the brush rods 205 to pass through.

[0046] Specifically, the drive assembly includes a turntable 202, a motor 201, a power supply 207, mounting rods 204, and an internal gear ring 208. The turntable 202 is rotatably mounted on the bottom surface of the cleaning chamber 101. The motor 201 and the power supply 207 are electrically connected and both are mounted on the base 10. The output end of the motor 201 is connected to the turntable 202. Multiple sets of mounting rods 204 are rotatably mounted on the turntable 202 corresponding to multiple sets of brush rods 205. The multiple sets of brush rods 205 are detachably mounted on the multiple sets of mounting rods 204. Each set of mounting rods 204 is equipped with a gear 203. An internal gear ring 208 is located at the bottom of the cleaning chamber 101, and the multiple sets of gears 203 mesh with the internal gear ring 208.

[0047] Specifically, in this embodiment, a limiting block 304 is provided around the fixed ring 303, and a limiting groove is provided around the cleaning cavity 101. The limiting block 304 can be locked in the limiting groove. The fixed ring 303 and the cleaning cavity 101 are snap-fit ​​connected, making it convenient to install and remove the fixed ring 303 and replace it, thereby facilitating the replacement of the scraper 301. A mounting groove 108 is provided at the bottom of the base 10, and the motor 201 is installed in the mounting groove 108. A sealing plate 1081 is fixed to the opening of the mounting groove 108 by bolts, which protects the motor 201. Multiple sets of through grooves 2081 are provided circumferentially around the internal gear ring 208. The through grooves 2081 prevent the accumulation of removed pulp tissue in the internal gear ring 208.

[0048] In the above embodiment, starting the motor 201 drives the turntable 202 to rotate. The rotation of the turntable 202 drives multiple sets of mounting rods 204 to rotate, which in turn drives multiple sets of brush rods 205 to rotate. Driving the multiple sets of brush rods 205 to rotate around the axis of the cleaning chamber 101 is convenient. The rotation of the multiple sets of brush rods 205 around the axis of the cleaning chamber 101 allows the brushes on the multiple sets of brush rods 205 to rotate around the periphery of the pulp extraction needle, thereby removing the pulp tissue on the pulp extraction needle. Simultaneously, the rotation of the multiple sets of mounting rods 204 drives the gear 203 to rotate and mesh with the internal gear ring 208. The rotation of the gear 203 meshes with the internal gear ring 208. 8 meshing causes gear 203 to rotate, which in turn drives mounting rod 204 to rotate. The rotation of mounting rod 204, in turn, drives brush rod 205 to rotate. The rotation of multiple brush rods 205 allows the brushes on the brush rods 205 to pass through the scraping groove 302 after contacting the pulp extraction needle. At this time, the scraping groove 302 can remove the pulp tissue attached to the brushes on the brush rods 205. After the pulp tissue on the brushes is removed, they can contact the pulp extraction needle again to clean the pulp extraction needle. This makes it easy to clean the pulp tissue attached to the brushes and prevents the pulp tissue attached to the brushes on the brush rods 205 from re-attaching to the pulp extraction needle, thus improving the cleaning effect of the device.

[0049] Based on the above embodiments, further, a connecting hole 2051 is provided on the brush rod 205 along its axis, the connecting hole 2051 is sleeved on the mounting rod 204, a positioning block is provided around the connecting hole 2051, a positioning groove 2041 is provided around the mounting rod 204, the positioning block can be locked in the positioning groove 2041, the top end of the mounting rod 204 extends to the outside of the connecting hole 2051, and is detachably connected to a limit plate 206.

[0050] In the above embodiment, the brush rod 205 can be moved upward by disassembling the limiting plate 206 to remove it from the mounting rod 204. The installation and disassembly of the brush rod 205 are convenient and easy to replace.

[0051] Please see Figure 2 , Figure 3 In one embodiment, it also includes a flushing assembly 40, which flushes the plucked needles in the cleaning chamber 101.

[0052] Specifically, the rinsing assembly 40 includes a water pump 401; a storage chamber 103 for storing disinfectant is provided in the side wall of the base 10, and an injection port 107 communicating with the storage chamber 103 is provided on the periphery of the base 10. A sealing cap 1071 is detachably provided on the injection port 107. The water pump 401 is mounted on the base 10 and electrically connected to the power supply 207. The water inlet pipe of the water pump 401 is connected to the bottom of the storage chamber 103. A diversion ring 403 is provided on the water outlet pipe 402 of the water pump 401. The diversion ring 403 is coaxially arranged with the cleaning chamber 101 and is located between the top of the cleaning chamber 101 and the positioning hole 102. Multiple sets of liquid outlets facing the axis of the cleaning chamber 101 are spaced apart along the circumference of the cleaning chamber 101 on the diversion ring 403.

[0053] In the above embodiment, by starting the water pump 401, the water pump 401 draws out the disinfectant in the storage chamber 103 and sprays it out from the outlet. At this time, the plucked needle in the cleaning chamber 101 can be rinsed, which further improves the cleaning effect on the plucked needle.

[0054] Please refer to the following: Figure 7 , Figure 8 Based on the above embodiments, a collection bottle 60 is detachably connected to the lower end of the base 10, and multiple drain ports 1011 communicating with the inner cavity of the collection bottle 60 are provided on the bottom surface of the cleaning chamber 101. Specifically, in this embodiment, the collection bottle 60 is threadedly connected to the lower end of the base 10, and observation windows 603 are provided on the periphery of both the collection bottle 60 and the base 10. By providing observation windows 603, it is convenient to observe the amount of disinfectant stored in the storage chamber 103 and the amount of waste liquid collected in the collection bottle 60, so as to facilitate timely addition of disinfectant and emptying of waste liquid.

[0055] In the above embodiment, by setting up a collection bottle 60, when rinsing the raping needle, the waste liquid generated during rinsing can flow into the collection bottle 60 through the drain port 1011, thereby avoiding contamination of the raping needle by immersing it in the waste liquid during rinsing.

[0056] Based on the above embodiments, a filter screen cover 602 is further provided inside the collection bottle 60, a support ring 601 is provided on the inner side wall of the collection bottle 60, and a boss 6021 is provided on the periphery of the filter screen cover 602, with the bottom end of the boss 6021 abutting against the top end of the support ring 601. By providing the filter screen cover 602, when waste liquid enters the collection bottle 60, the waste liquid will pass through the filter screen cover 602. At this time, the filter screen cover 602 can filter out the dental pulp tissue in the waste liquid, thereby performing solid-liquid separation, which facilitates the separate treatment of dental pulp tissue and waste liquid. Furthermore, the filter screen cover 602 can be removed from the collection bottle 60 by moving the filter screen cover 602 upward to separate the boss 6021 from the support ring 601, making the installation and removal of the filter screen cover 602 convenient.

[0057] The specific implementation method of the above-mentioned bone marrow plucking needle cleaning device is as follows:

[0058] First, by applying force to the two sets of clamping plates 503, the two sets of clamping plates 503 are moved relatively away from each other. The relative movement of the two sets of clamping plates 503 can squeeze the elastic element 501. Then, the tip of the plucked needle passes through the positioning hole 102 and the diversion ring 403 and is located between the multiple sets of brush rods 205 in the cleaning chamber 101, and the holding part of the plucked needle is located between the two sets of clamping plates 503. Then, the force applied to the two sets of clamping plates 503 is released. At this time, the reaction force of the elastic element 501 causes the two sets of clamping plates 503 to move relatively closer. The relative movement of the two sets of clamping plates 503 can clamp the holding part of the plucked needle, thereby fixing the plucked needle on the top cover 104.

[0059] Then, the motor 201 and water pump 401 are started by the power supply 207. The start of the motor 201 drives the turntable 202 to rotate. The rotation of the turntable 202 drives the multiple sets of mounting rods 204 to rotate. The rotation of the multiple sets of mounting rods 204 drives the multiple sets of brush rods 205 to rotate around the axis of the cleaning chamber 101. The rotation of the multiple sets of brush rods 205 around the axis of the cleaning chamber 101 causes the brushes on the multiple sets of brush rods 205 to rotate around the periphery of the pulp extraction needle, thereby removing the pulp tissue on the pulp extraction needle. At the same time, the rotation of the multiple sets of mounting rods 204 drives the gear 203 to rotate and mesh with the internal gear ring 208. The rotation of the gear 203 meshes with the internal gear ring 208. 8 meshing causes gear 203 to rotate, which in turn drives mounting rod 204 to rotate. The rotation of mounting rod 204, in turn, drives brush rod 205 to rotate. The rotation of multiple brush rods 205 allows the brushes on the brush rods 205 to pass through the scraping groove 302 after contacting the pulp extraction needle. At this time, the scraping groove 302 can remove the pulp tissue attached to the brushes on the brush rods 205. After the pulp tissue on the brushes is removed, they can contact the pulp extraction needle again to clean the pulp extraction needle. This makes it easy to clean the pulp tissue attached to the brushes and prevents the pulp tissue attached to the brushes on the brush rods 205 from re-attaching to the pulp extraction needle, thus improving the cleaning effect of the device.

[0060] When the water pump 401 is started, it draws out the disinfectant from the storage chamber 103 and sprays it out from the outlet of the diversion ring 403. At this time, the pulp extraction needle can be rinsed. By brushing away the pulp tissue on the pulp extraction needle while rinsing it, the cleaning effect of the pulp extraction needle is further improved.

[0061] Meanwhile, the waste liquid generated after rinsing the pulp extraction needle can flow into the collection bottle 60 through the drain port 1011, thereby avoiding the pulp extraction needle from being soaked in the waste liquid and causing contamination during rinsing. When the waste liquid enters the collection bottle 60, it will pass through the filter cover 602, which can filter out the pulp tissue in the waste liquid, thereby separating the solid and liquid and facilitating the separate treatment of the pulp tissue and the waste liquid.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
