Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a medical injection needle blade angle adjustment component. Background Technology

[0002] Injection is a common medical technique. In cosmetic medicine, to ensure better and more even absorption of the injected medication, multi-needle needles, such as nine-needle injection needles, are usually used.

[0003] However, existing nine-needle injection needles have thinner tubes and smaller gaps between them. Therefore, it is difficult to control the angle of the needle blade after the tubes are installed. This results in each needle blade facing a different direction. During use, due to the different angles of the cutting blades, each needle exerts a different force on the user. Consequently, some needles are easy to insert into the human body, while others are difficult to insert, increasing the user's pain. Summary of the Invention

[0004] This invention provides a medical injection needle blade angle adjustment component, which aims to at least solve one of the technical problems existing in the prior art.

[0005] The technical solution of the present invention is a medical injection needle blade angle adjustment component, which includes:

[0006] The needle feeding mechanism is used to grasp the needle tube and position it vertically.

[0007] The steering mechanism includes a first power component and a first adjusting plate. The first adjusting plate is provided with a first adjusting rod. The first power component is used to drive the first adjusting plate to approach the needle tube, so that the outer wall of the first adjusting rod can abut against the needle tube, thereby causing the needle tube to rotate around its own axis.

[0008] The positioning mechanism includes a cutting block and a second power component. The cutting block has a guide surface adapted to the cutting edge of the needle tube. The second power component is used to drive the cutting block to move closer to or away from the needle tube.

[0009] The needle-carrying mechanism, the turning mechanism, the positioning mechanism, and the needle-receiving mechanism are arranged sequentially from top to bottom.

[0010] Furthermore, the needle delivery mechanism includes an adsorption element, which has a plurality of first needle grooves. The adsorption element is used to grasp the needle tube and place the needle tube in the first needle grooves in the vertical direction.

[0011] Furthermore, the steering mechanism also includes a second adjusting plate, which is provided with a second adjusting rod. The first power component is used to drive the first adjusting plate and the second adjusting plate to move closer or further away from each other, so that the outer walls of the first adjusting rod and the second adjusting rod can abut against the needle tube, thereby causing the needle tube to rotate around its own axis.

[0012] Furthermore, the top of the first adjusting rod is chamfered.

[0013] Furthermore, the first adjusting rod is a cylindrical structure, and the first adjusting rod is perpendicular to the needle tube.

[0014] Furthermore, the first power component is a bidirectional lead screw, which can simultaneously drive the first adjusting plate and the second adjusting plate to move closer or further apart.

[0015] Furthermore, the first adjusting rod is rotatably mounted on the first adjusting plate.

[0016] Furthermore, the surfaces of the first adjusting rod and / or the second adjusting rod are provided with a friction layer, which is used to abut against the needle tube.

[0017] Furthermore, it also includes a needle receiving mechanism, which includes a needle holder and a fourth power component. The needle holder has a needle hole, and the fourth power component is used to drive the needle holder closer to the needle tube so that the needle tube is inserted into the needle holder.

[0018] The technical solution of the present invention is a method of using a medical injection needle blade angle adjustment component, comprising the following steps:

[0019] The adsorption element adsorbs the needle tube, and the needle tube is adsorbed into the first needle groove, so that the first needle groove is set in the vertical direction.

[0020] The second power component drives the cutting block to move closer to the bottom of the needle tube, so that the guide surface of the cutting block is directly below the needle tube;

[0021] The adsorption element reduces the suction force, and the needle falls vertically due to gravity. The lower end of the needle abuts against the guide surface, and at least part of the needle structure is located in the adsorption element.

[0022] The first power component drives the first adjusting plate to approach the needle tube, causing the first adjusting rod to abut against the needle tube and continue to move, causing the needle tube to rotate around its own axis until the cutting surface of the needle tube mates with the guide surface of the cutting block.

[0023] The first power component drives the first adjustment plate away from the needle tube, the suction component enhances the suction force, fixes the needle tube on the suction component, and the first adjustment plate and the cut block are reset.

[0024] The fourth power component drives the needle holder to approach the needle tube from bottom to top, so that the needle tube is inserted into the needle hole;

[0025] The adsorption component stops working, and the fourth power component drives the needle holder to move away from the adsorption component from top to bottom.

[0026] The beneficial effects of this invention are as follows.

[0027] The needle tube is positioned vertically by the suction component of the needle-feeding mechanism. Gravity forces the needle tube to fall vertically. After falling, the lower end of the needle tube abuts against the cutting block. The needle tube is at its lowest point and cannot rotate relative to itself only when the cutting edge of the needle tube precisely aligns with the guide surface of the cutting block. When the cutting edge of the needle tube does not align with the guide surface of the cutting block, the needle tube is in a relatively higher position and can rotate relative to its own axis. When the first power component of the steering mechanism drives the first adjusting plate closer to the needle tube, the first adjusting rod abuts against it. The needle tube, due to the friction between the first adjusting rod and the needle tube, can rotate relative to itself. When the needle tube rotates to a certain angle, it continues to fall, and the direction of the needle tube's cutting edge changes. Finally, the angle between the cutting edge of the needle tube and the guide angle of the cutting block is matched, so that the cutting edge of each needle tube can face the same direction. The suction component holds the needle tube in the first needle groove. When the suction force of the suction component is reduced, the needle tube can slide down along the first needle groove. At the same time, several needle tubes are set so that several first adjusting rods can drive several needle tubes to rotate simultaneously, improving work efficiency. Attached Figure Description

[0055] Reference Figures 1-13 A basic embodiment of the first aspect of the present invention provides a medical injection needle blade angle adjustment component, comprising:

[0056] The needle delivery mechanism 100 includes an adsorption member 110. The adsorption member 110 is provided with a plurality of first needle grooves 111. The adsorption member 110 is used to grasp the needle tube and place the needle tube in the first needle grooves 111 in the up-down direction.

[0057] The steering mechanism 200 includes a first power member 210 and a first adjusting plate 220. The first adjusting plate 220 is provided with a first adjusting rod 221. The first power member 210 is used to drive the first adjusting plate 220 to approach the needle tube, so that the outer wall of the first adjusting rod 221 can abut against the needle tube, thereby causing the needle tube to rotate around its own axis.

[0058] The positioning mechanism 300 includes a cutting block 310 and a second power member 320. The cutting block 310 is provided with a guide surface 311, which is adapted to the cutting edge of the needle tube. The second power member 320 is used to drive the cutting block 310 to move closer to or away from the needle tube.

[0059] The needle-feeding mechanism 100, the turning mechanism 200, and the positioning mechanism 300 are arranged sequentially from top to bottom.

[0060] A medical injection needle blade angle adjustment assembly according to a basic embodiment of the first aspect of the present invention, wherein the needle tube is positioned vertically by means of the suction member 110 of the needle transport mechanism 100, and the needle tube can be driven vertically by gravity. After the needle tube falls, the lower end of the needle tube abuts against the cutting block 310. Only when the blade of the needle tube is exactly engaged with the guide surface 311 of the cutting block 310, the needle tube is at its lowest point and cannot rotate relative to itself. When the blade of the needle tube is not engaged with the guide surface 311 of the cutting block 310, the needle tube is at a relatively higher position, and the needle tube can rotate relative to its own axis. The first power member 210 of the steering mechanism 200 drives the first adjustment plate 22. When the needle approaches the syringe, the first adjusting rod 221 can abut against the syringe. Due to the friction between the first adjusting rod 221 and the syringe, the syringe can rotate relative to itself. After the syringe rotates to a certain angle, the syringe continues to fall, and the direction of the syringe blade changes. Finally, the angle of the syringe blade and the guide angle of the cutting block 310 match, so that the blade of each syringe can face the same direction. The suction member 110 suctions the syringe to the first needle groove 111. When the suction force of the suction member 110 is reduced, the syringe can slide down along the first needle groove 111. At the same time, several syringes are set so that several first adjusting rods 221 can drive several syringes to rotate at the same time, improving work efficiency.

[0061] It is understandable that the first power component 210 is a lead screw or a telescopic cylinder, and the second power component 320 is a lead screw or a telescopic cylinder.

[0062] In some embodiments, the steering mechanism 200 further includes a second adjusting plate 230, which is provided with a second adjusting rod 231. A first power member 210 is used to drive the first adjusting plate 220 and the second adjusting plate 230 to move closer or further apart, so that the outer walls of the first adjusting rod 221 and the second adjusting rod 231 can abut against the needle tube, thereby causing the needle tube to rotate around its own axis. The first adjusting plate 220 and the second adjusting plate 230 are close to each other and are located on both sides of the needle tube, so that the first adjusting plate 220 and the second adjusting plate 230 abut against both sides of the needle tube, increasing the horizontal friction between the needle tube and the adjusting rod, so that the needle tube can rotate effectively and preventing the needle tube from being too smooth or too thin to rotate.

[0063] In some embodiments, the top end of the first adjusting rod 221 is provided with a chamfer 221a. The chamfer 221a provided at the top end of the first adjusting rod 221 can reduce the diameter of the top end of the first adjusting rod 221, so that the first adjusting rod 221 is not obstructed when passing through the needle tube, allowing the first adjusting rod 221 to be inserted into the needle tube; the same applies to the second adjusting rod 231.

[0064] In some embodiments, the first adjusting rod 221 is a cylindrical structure, and the first adjusting rod 221 is perpendicular to the needle tube. Both the first adjusting rod 221 and the needle tube are cylindrical structures, and there is point-to-point contact between them to prevent excessive vertical friction between the first adjusting rod 221 and the needle tube, which would prevent the needle tube from falling onto the cut surface block 310 in the vertical direction.

[0065] In some embodiments, the first power component 210 is a bidirectional lead screw, which can simultaneously drive the first adjusting plate 220 and the second adjusting plate 230 to move closer or further apart. A bidirectional lead screw is a left-hand and right-hand lead screw; one part of the threaded portion of the lead screw is left-handed, and the other part is right-handed. When the lead screw rotates in one direction, the two nuts on the thread separate or move closer together; when it rotates in the opposite direction, the two nuts move closer together or separate. The bidirectional lead screw simultaneously drives the first adjusting plate 220 and the second adjusting plate 230, making their movement speeds the same but in opposite directions. Consequently, the movement speeds of the first adjusting rod 221 and the second adjusting rod 231 are also the same, which is beneficial for the first adjusting rod 221 and the second adjusting plate 230 to drive the needle tube to rotate. The lead screw has high transmission efficiency and accurate positioning, which is beneficial for the needle tube to rotate to the corresponding angle.

[0066] In some embodiments, the first adjusting rod 221 is rotatably disposed on the first adjusting plate 220. The first adjusting rod 221 can rotate about its own axis. When the needle tube falls, the first adjusting rod 221 rotates with the needle tube, so that the lower end of the needle tube can remain in contact with the cutting block 310. The second adjusting rod 231 is similar to the first adjusting rod 221.

[0067] In some embodiments, the surfaces of the first adjusting lever 221 and / or the second adjusting lever 231 are provided with a friction layer for contacting the syringe. The friction layer is made of rubber-based friction material, paper-based friction material, resin-based friction material, carbon fiber friction material, or semi-metallic friction material.

[0068] In some embodiments, a locking mechanism 400 is also included, the locking mechanism 400 comprising:

[0069] Pressure plate 410;

[0070] The third power component 420 is used to drive the pressure plate 410 to approach the adsorption component 110 from back to front, so that the needle is fixed on the adsorption component 110.

[0071] In this configuration, when the cut block 310 and the first adjusting rod 221 move away from the needle, the needle may fall vertically due to gravity exceeding the suction force of the adsorption member 110. The needle is then fixed to the adsorption member 110 by the pressure plate 410 abutting against it.

[0072] In some embodiments, the pressure plate 410 is provided with a protrusion 411, which is adapted to the first needle groove 111 and can abut against the needle tube, thereby fixing the needle tube on the suction member 110. The protrusion 411 can penetrate deep into the first needle groove 111, so that the protrusion 411 abuts against the needle tube, and the protrusion 411 and the needle tube are in full contact, thereby improving the stability of the needle tube.

[0073] In some embodiments, the protrusion 411 is made of elastic materials such as rubber and silicone. By squeezing the needle tube with the protrusion 411, the protrusion 411 deforms under force, so that the needle tube is fixed on the adsorption member 110.

[0074] In some embodiments, the needle delivery mechanism 100 further includes a guide block 120, which has a guide hole 121 adapted to the diameter of the needle tube, so that the needle tube is positioned in the vertical direction. The inner diameter of the first needle groove 111 is larger than the diameter of the needle tube, so that the needle tube can pass through the guide hole 121 and perform other operations, preventing the needle tube from shifting during rotation, which would affect the installation of the needle tube.

[0075] In some embodiments, the circular edge formed at the lower end of the guide hole 121 is inscribed in the circular edge formed by the first needle groove 111. It can be understood that, viewed from the front-back or left-right direction, the lower end of the guide hole 121 and the first needle groove 111 are not on the same plane. However, viewed from the top-bottom direction, the lower end of the guide hole 121 and the first needle groove 111 are inscribed in the same plane, so that the needle tube can move along the first needle groove 111 and along the guide hole 121. The needle tube can maintain a straight line movement in the top-bottom direction without changing direction, thus preventing the needle tube from deviating.

[0076] In some embodiments, the upper end of the guide hole 121 is adapted to the diameter of the first needle groove 111, and the lower end of the guide hole 121 is adapted to the diameter of the needle tube. The guide hole 121 gradually decreases in size from top to bottom. The inner diameter of the first needle groove 111 is larger than the diameter of the needle tube, allowing the needle tube to pass through the guide hole 121 for other operations, preventing the needle tube from shifting during rotation and affecting the installation of the needle tube.

[0077] In some embodiments, the device further includes a needle retraction mechanism 500, which includes a needle holder 510 and a fourth power member 520. The needle holder 510 has a needle hole 511, and the fourth power member 520 is used to drive the needle holder 510 closer to the needle tube, so that the needle tube is inserted into the needle holder 510. The fourth power member 520 drives the needle holder 510 to move in the up-down and back-forward directions, so that the needle holder 510 can enter the device in the back-forward direction, and then insert the needle tube into the needle holder 510 in the up-down direction.

[0078] It is understandable that the fourth power component 520 is a combination of two guide rails, or it could be a combination of two telescopic cylinders.

[0079] In some embodiments, a dispensing mechanism 600 is further included. The dispensing mechanism 600 includes a dispensing device 610 and a seventh power member 620. The dispensing device 610 is located directly above the positioning mechanism 300. The seventh power member 620 is used to drive the dispensing device 610 closer to or further away from the needle hole 511. By driving the dispensing device 610 closer to the needle hole 511 through the seventh power member 620, glue is injected into the connection between the needle tube and the needle hole 511, thereby fixing the needle tube onto the needle holder 510.

[0080] In some embodiments, the dispensing device 610 is provided with an alignment plate 611, which is arranged in the left-right direction. The alignment plate 611 is used to drive the needle tubes to move downward so that multiple needle tubes are at the same height. When the seventh power member 620 drives the dispensing device 610 to press down, it also drives the pressure plate 410 to move downward, causing the needle tubes to move downward simultaneously, ensuring that the needle tubes are at the same height.

[0081] In some embodiments, a detection mechanism is also included, comprising an infrared detector for detecting whether the needle is in position. The infrared detector emits infrared light. When the needle is fully engaged with the cut surface block 310, the needle is at its lowest point. The infrared light illuminates the lowest point, and the needle's position is determined by whether it is in that position.

[0082] In some embodiments, the adsorption member 110 is provided with a negative pressure hole, which is located in the first needle groove 111 and is connected to a negative pressure fan. The negative pressure fan fixes the negative pressure hole in the first needle groove 111, facilitating the transfer of the needle tube by the adsorption member 110.

[0083] In some embodiments, the adsorption element 110 is equipped with an electromagnet, and the adsorption effect of the adsorption element 110 can be controlled by controlling the switching on and off of the power or adjusting the magnitude of the power.

[0084] In some embodiments, the needle-feeding mechanism 100 further includes:

[0085] The base 130 is provided with a needle storage slot for storing needle tubes. The base 130 is provided with several through holes located at the lower end of the needle storage slot.

[0086] The pickup arm 140 includes a pin 141, a fifth power member 143, and a sixth power member 144. The pin 141 passes through a through hole. The adsorption member 110 is provided with a plurality of first needle grooves 111, each corresponding to a through hole. The adsorption member 110 is rotatably mounted on the base 130. The sixth power member 144 drives the adsorption member 110 to rotate around the base 130. The sixth power member 144 is used to drive the adsorption member 110 to rotate above the base 130. The fifth power member 143 drives the pin 141 to approach the adsorption member 110 from bottom to top, so that the needle tube on the base 130 approaches the adsorption member 110, and thus the needle tube is adsorbed on the first needle grooves 111.

[0087] In this configuration, a large number of needles are stored in the base 130. The ejector pin 141 moves from bottom to top, passing through a large number of needles. During the upward movement, one needle is positioned at the top of the ejector pin 141, while the remaining needles remain in the needle storage slot. The sixth power unit 144 drives the suction unit 110 to rotate above the base 130. The ejector pin 141 moves the needles onto the suction unit 110, which then adsorbs the needles onto the first needle slot 111. The fifth power unit 143 drives the suction unit 110 to rotate in front of the base 130, arranging the needles vertically. The entire process of picking up and collecting needles does not require manual operation and can process multiple needles simultaneously, effectively improving production efficiency and ensuring the safety of workers.

[0088] It is understandable that the first needle groove 111 is a concave structure, allowing the needle tube to extend into the first needle groove 111. The first needle groove 111 can be a V-shaped groove, an arc-shaped groove, or a square groove.

[0089] It is understandable that the first needle groove 111 is located on the side of the adsorption member 110 near the base 130. When the second power member 320 drives the adsorption member 110 to rotate above the base 130, the first needle groove 111 faces downward. When the second power member drives the adsorption member 110 to rotate in front of the base 130, the first needle groove 111 faces backward.

[0090] In some embodiments, the ejector pin 141 includes a plurality of ejector pins, which pass through corresponding through holes. The plurality of ejector pins are arranged in a vertical direction. The first power member 210 drives the ejector pin 141 to move upward, which can drive multiple ejector pins to move simultaneously, so that each ejector pin can pick up one of the needle tubes.

[0091] In some embodiments, the upper end of the ejector pin is provided with a third needle groove, which is used to mate with the needle tube. The shape of the third needle groove is exactly to match the needle tube. During the upward stroke of the ejector pin, the upper end of the ejector pin will pass through the needle storage slot containing a large number of needle tubes. During this stroke, only one needle tube can be installed into the third needle groove, and the remaining needle tubes remain in the needle storage slot, ensuring that each ejector pin picks up only one needle tube.

[0092] In some embodiments, the left and right ends of the first needle groove 111 are respectively provided with a first inclined surface and a second inclined surface, which are used to separate excess needle tubes from the ejector pin 141. Only one needle tube can be installed on the third needle groove, and the remaining needle tubes slide down along the first inclined surface and the second inclined surface, further ensuring that each ejector pin picks up only one needle tube.

[0093] A method of using a medical injection needle blade angle adjustment component according to a basic embodiment of the second aspect of the present invention includes the following steps:

[0094] The adsorption element 110 adsorbs the needle tube and adsorbs the needle tube into the first needle groove 111, so that the first needle groove 111 is set in the vertical direction.

[0095] The second power unit 320 drives the cutting block 310 to move closer to the bottom of the needle tube, so that the guide surface 311 of the cutting block 310 is directly below the needle tube.

[0096] The suction force is reduced by the adsorption element 110, and the needle falls vertically due to gravity. The lower end of the needle abuts against the guide surface 311, and at least part of the needle structure is located in the adsorption element 110.

[0097] The first power component 210 drives the first adjusting plate 220 to approach the needle tube, so that the first adjusting rod 221 abuts against the needle tube and continues to move, so that the needle tube rotates around its own axis until the cutting surface of the needle tube matches the guide surface 311 of the cutting block 310.

[0098] The first power component 210 drives the first adjustment plate 220 away from the needle tube, the suction component 110 enhances the suction force, fixes the needle tube on the suction component 110, and the first adjustment plate 220 and the cut block 310 are reset.

[0099] The fourth power unit 520 drives the needle holder 510 to approach the needle tube from bottom to top, so that the needle tube is inserted into the needle hole 511;

[0100] When the adsorption element 110 stops working, the fourth power element 520 drives the needle holder 510 to move away from the adsorption element 110 from top to bottom.

[0101] The adsorption component 110 moves away from the needle holder 510, and the seventh power component 620 drives the dispensing device 610 to move downward, injecting glue into the connection between the needle tube and the needle holder 510, so that the needle tube is fixed on the needle holder 510.

[0102] In this configuration, the needle tube is positioned vertically by the suction element 110 of the needle-feeding mechanism 100. The needle tube is driven vertically by gravity. After falling, the lower end of the needle tube abuts against the cutting block 310. At least a portion of the needle tube's structure is located within the suction element 110, which serves to limit its movement. Only when the cutting edge of the needle tube precisely mates with the guide surface 311 of the cutting block 310 is the needle tube at its lowest point and unable to rotate relative to itself. When the cutting edge of the needle tube does not mate with the guide surface 311 of the cutting block 310, the needle tube is at its lowest point. At a relatively high position, the needle tube can rotate relative to its own axis. When the first power component 210 of the steering mechanism 200 drives the first adjusting plate 220 to approach the needle tube, the first adjusting rod 221 can abut against the needle tube. Due to the friction between the first adjusting rod 221 and the needle tube, the needle tube can rotate relative to itself. When the needle tube rotates to a certain angle, the needle tube continues to fall, and the direction of the needle tube blade changes. Finally, the angle of the needle tube blade and the guide angle of the cutting block 310 match, so that the blade of each needle tube can face the same direction.
