DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] See also Figures 1 to 18 The embodiment of the utility model provides a microneedle clamping device, including a gripping portion 1 and a grasping assembly, wherein the grasping assembly includes a grasping head 20 for grasping or releasing the microneedle 6 and a driving member for controlling the movement of the grasping head 20, wherein the grasping head 20 is detachably mounted on one end of the gripping portion 1, and the driving member is disposed on the gripping portion 1. In this embodiment, by refining the grasping action into the grasping head 20 and the driving member, a refined grasping action can be achieved, the clamping effect is better and the microneedle 6 is not easily damaged. In addition, by adopting the form of detachable connection of the grasping head 20, the adapted grasping head 20 can be replaced according to the different types of implanted microneedles 6, so that the adaptability of the present microneedle clamping device is higher. Specifically, the gripping portion 1 can be grasped by a human hand or a robot. When grasped by a human hand, the microneedle is manually implanted, and when grasped by an automated structure, the microneedle is automatically implanted, such as by a robot drive, a pneumatic drive, etc.

[0040] There are two implementation methods for crawling, such as Figures 1 to 6 , which is a clamping grasping method; such as Figures 7 to 18 , which is an adsorption-type grabbing method. The following are two specific grabbing methods.

[0041] See also Figures 1 to 6The gripping head 20 includes a first clamping block 200 and a second clamping block 201 that are arranged opposite to each other. The first clamping block 200 and the second clamping block 201 are between a clamping interval for clamping the microneedle. The driving member drives the first clamping block 200 and / or the second clamping block 201 to move to adjust the size of the clamping interval. In this embodiment, the microneedle is grasped by clamping. This grasping method is most suitable for grasping the surface array microneedle. Of course, by controlling the accuracy of the clamping method, it can also be used for the clamping of a single needle, such as small animal microneedles, large animal microneedles, etc., and the anti-slip structure, anti-damage structure, etc. are designed to ensure the safe clamping of a single needle. For example, rubber surface clamping can be used for anti-slip and anti-damage. Specifically, the first clamping block 200 and the second clamping block 201 are used to clamp the microneedle. When the two cooperate, there is a clamping interval between them. The first clamp 200 and the second clamp 201 can be driven by a driving member. One of the clamps can move, or both can move. This embodiment does not limit this. The purpose is to change the size of the clamping interval to clamp or release the microneedle.

[0042] To further optimize the above solution, please refer to Figures 1 to 6The driving member includes a push rod 210 for driving the first clamping block 200 to approach or move away from the second clamping block 201 , and the push rod 210 is movably disposed on the gripping portion 1 . In this embodiment, a push rod 210 can be used to drive the first clamp 200 to approach or move away from the second clamp 201. The pushing direction of the push rod 210 can be set in a variety of ways. The pushing direction can be consistent with the moving direction of the first clamp 200, or it can be vertical. When the directions are consistent, the pushing direction of the push rod 210, the first clamp 200 and the second clamp 201 are in a straight line. At this time, the push rod 210 can be placed outside the gripping portion 1. At this time, the push rod 210 and the first clamp 200 can be fixedly installed, so that the push rod 210 can push or retract the first clamp 200. When the first clamp 200 is pushed, the microneedle is clamped (grasped), and when the first clamp 200 is retracted, the microneedle is released; when the direction is vertical, the contact surface of the push rod 210 with the first clamp 200 is an inclined surface 2. 11, and the pushing direction of the push rod 210 is perpendicular to the moving direction of the first clamp 200, and the first clamp 200 is provided with a first return spring 212, and the direction of the driving force is decomposed by the inclined surface 211, so that the moving direction of the first clamp 200 can be perpendicular to the pushing direction of the push rod 210, so that the push rod 210 can be placed in the gripping part 1, at this time, because the force is decomposed by the inclined surface 211, the push rod 210 cannot be fixed with the first clamp 200, otherwise there will be no relative sliding between the two, and the first clamp 200 cannot be pushed, then the first return spring 212 can be used to achieve the reset of the first clamp 200, when the first return spring 212 is compressed, the microneedle is clamped (grasped), and when the first return spring 212 is reset, the microneedle is released. Preferably, a guide rod 218 is provided to assist the movement of the first clamp 200, and the guiding direction of the guide rod 218 is consistent with the moving direction of the first clamp 200.

[0043] As an optimization solution of the embodiment of the utility model, please refer to Figures 1 to 6 The driving member further comprises a control button 213 movably mounted on the grip portion 1 and a connecting rod mounted on the push rod 210, wherein the connecting rod is fixed on the control button 213. In this embodiment, the push rod 210 can be driven to move by the cooperation of the control button 213 and the connecting rod. The control button 213 can be mounted on the grip portion 1 in a threaded manner, so that the control button 213 can be screwed to adjust the up and down movement of the control button 213, thereby driving the push rod 210 to move through the connecting rod. The connecting rod can be a screw rod 214, and a threaded hole is provided on the push rod 210 for the screw rod 214 to be installed.

[0044] As an optimization solution of the embodiment of the utility model, please refer to Figures 1 to 6, a second return spring 215 is installed on the push rod 210. In this embodiment, the second return spring 215 can be used to realize the automatic return of the push rod 210. For example, after the pressing force on the push rod 210 is removed (i.e., the control button 213 is turned upward), the push rod 210 can move upward under the action of the second return spring 215, thereby removing the pressure on the first clamping block 200, and the first clamping block 200 can be moved away from the second clamping block under the action of the first return spring 212.

[0045] See also Figures 7 to 18 The gripping head 20 may be a suction nozzle 202, and the driving member may be a negative pressure mechanism that provides suction force for the suction nozzle 202. In this embodiment, the suction nozzle 202 and the negative pressure mechanism may be used in combination to achieve adsorption of microneedles, and this adsorption is not only suitable for single needles and multiple needles, but also for area array microneedles.

In this embodiment, the above-mentioned negative pressure mechanism can be refined into an air pipe 217 and a negative pressure generating device 216. The air pipe 217 can be built into the gripping portion 1 or laid outside the gripping portion 1, which is not limited in this embodiment. The purpose of the air pipe 217 is to provide negative pressure, so its two ends need to be respectively connected to the suction nozzle 202 and the negative pressure generating device 216. The suction nozzle 202 is threadedly connected to the air pipe 217. The negative pressure generating device 216 can be a separate component or a component fixedly mounted on the gripping portion 1.

The number of suction points can be designed according to needs. Fig. 22 The figure shows a surface array nozzle. Since the surface array microneedles are in the shape of a whole plate, only adsorption points need to be designed on both sides to adsorb the entire surface array microneedles. Preferably, the nozzle includes a suction block with a built-in airway, and the suction block has adsorption points, and the adsorption points are connected to the airway. The nozzle can be refined into a suction block, and the suction block has an airway and adsorption points are provided on the bottom surface, so that the microneedles can be adsorbed.
