Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present invention more apparent.
Reference is made to the schematic structural diagram shown in fig. 1.
The embodiment of the invention discloses a multifunctional hair follicle transplanting device which comprises a drilling mechanism, a hair follicle clamping/cutting mechanism and a hair follicle pushing mechanism.
The drilling mechanism comprises a first driving mechanism, a planting head shell 12 linked with the first driving mechanism and a needle head 1 fixedly arranged on the planting head shell 12;
the first drive mechanism comprises a spindle motor 14, the spindle motor 14 having a hollow main motor rotation shaft 5, and a push-out needle 15 being disposed in the needle head 1 via the hollow main motor rotation shaft 5.
The hair follicle clamping/cutting mechanism comprises a pair of clamping pieces 2 rotatably arranged on the planting head shell 12 and a pushing mechanism, the needle head 1 is provided with a slot, the clamping heads of the pair of clamping pieces 2 are arranged in the slot, and the pushing mechanism is used for driving the pair of clamping pieces 2 to rotate to clamp/cut.
More specifically, a pair of clips 2 are positioned on either side of the needle 1 and extend into the needle for movement through the slot. The clamping piece is arranged on the planting head shell by the cylindrical pin 10, and can rotate slightly around the cylindrical pin 10.
The hair follicle pushing mechanism comprises a pushing needle 15 arranged in the needle head 1, and the pushing needle 15 is driven to push by the second driving mechanism.
The pushing mechanism comprises a pushing piece which acts on the clamping of the pair of clips 2 in a sliding way and a third driving mechanism for driving the pushing piece.
The hair follicle clamping/cutting mechanism converts the power of a power source (a motor, an air cylinder or an electromagnet) into the pressure of the clamping piece through the pushing piece, so that the clamping piece is pushed to rotate, the position between the two clamping pieces is reduced, and the pressure is applied to the surface of the content of the needle tube, so that the clamping or cutting effect is realized.
A clip return spring 11 is provided between the pair of clips 2 and the planting head housing 12.
A pusher return spring 7 is arranged between the pusher and the planter housing 6.
The pushing member is a push rod or a push sleeve, in this embodiment, the pushing sleeve 3 is preferred, the third driving mechanism is a motor, a cylinder or an electromagnet, and likewise, in this embodiment, the cylinder is preferred, the cylinder body 8 is fixedly arranged on the casing of the transplanting device through nuts 20 and 21, the tail end of the cylinder piston rod 9 acts on the top end of the pushing sleeve 3, and the pushing sleeve 3 is reset through the pushing member reset spring 7.
The hair follicle pushing mechanism also comprises a sliding block 17 fixedly provided with a pushing needle 15, and a pushing needle return spring 16 is arranged between the sliding block 17 and the transplanting device shell 6.
The second driving mechanism is a motor, a cylinder or an electromagnet, and in this embodiment, a motor 19 is preferable, a cam 18 is linked to the motor 19, and the cam 18 is in contact fit with the sliding block 17.
Alternatively, the second driving mechanism may be a motor, and the sliding block 17 is driven to stretch and retract by the sliding block and the link mechanism, so that the push-out needle 15 pushes out the hair follicle clamped by the clamping piece.
In use, as shown in fig. 2, the spindle motor 14 is activated to drive the needle 1 to perform a rotational movement. The planting pen is moved by hand along the hair growth direction, the needle tube on the needle head 1 performs circular cutting movement on the skin, and the tissue around the hair follicle is ruptured. When moving to a certain depth, the spindle motor 14 stops moving by the button control. The electromagnetic valve is controlled to move through the button, the air cylinder moves forwards to drive the push sleeve 3 to move forwards, and the push sleeve 3 extrudes the clamping piece 2. The clip 2 rotates slightly around the cylindrical pin 10 due to the extrusion force, the space between the two clips is reduced, and the hair follicle tissue between the two clips is clamped or cut off. The planting pen is lifted up, and the hair follicle is pulled up and remains in the drill head needle tube. The button is used for controlling the electromagnetic valve to move, the air cylinder moves backwards, the pushing sleeve 3 does not squeeze the clamping piece any more, and the clamping piece 2 returns to the original position by the force of the clamping piece return spring 11. The pen is moved over the delivery area, as shown in fig. 3, the drill head needle is inserted into the pre-drilled hole, the motor 19 is activated by the button, and the motor moves the cam 18, causing the ejector pin 15 to move forward along the needle head, ejecting the hair follicle. The planting pen is pulled out, the hair follicle is left in the new planting hole, the scalp is contracted to tightly wrap the hair follicle, and the device is reset, so that the planting process is completed.
The above disclosure is only a preferred embodiment of the present invention, and it is needless to say that the scope of the invention is not limited thereto, and therefore, the equivalent changes according to the claims of the present invention still fall within the scope of the present invention.
