Detailed implementation manners

[0026] The present invention will be further described below with reference to the specific drawings and embodiments.

[0027] As Figures 1 to 3 shown, the embodiment discloses an intelligent fire needle, which mainly consists of a pen - shaped grip 1, a treatment needle 2 and a quick - release locking device. The pen - shaped grip 1 is held by medical staff during use. The front end of the pen - shaped grip 1 is equipped with a quick - release locking device, and the treatment needle 2 is installed on the quick - release locking device in a detachable and replaceable manner. The treatment needle 2 is electrically connected to an operating instrument (not shown in the figure) that can control the temperature. The operating instrument can adopt conventional products in the prior art, and during clinical use, the required temperature can be adjusted according to the treatment needs, which not only reduces unnecessary thermal damage, prevents pigmentation and erythema, but also avoids the trouble and risks of heating with an alcohol lamp.

[0028] In this embodiment, the quick - release locking device mainly consists of an electric push rod 3, an outer housing 4, a dual - purpose shaft 5, a transmission ring 6, a holding spring 7, a needle - holding rubber sleeve 8, etc. The electric push rod 3 is installed inside the pen - shaped grip 1 and serves as the driving component of the quick - release locking device. A forward - moving button 9 and a backward - moving button 10 for controlling the electric push rod 3 are installed on the pen - shaped grip 1. The outer housing 4 is installed at the front end of the pen - shaped grip 1. The dual - purpose shaft 5 is arranged inside the outer housing 4 and is connected to the front end of the core rod 3a of the electric push rod 3. The transmission ring 6 is sleeved on the dual - purpose shaft 5. A direction - changing transmission structure is arranged between the dual - purpose shaft 5 and the transmission ring 6, and the direction - changing transmission structure can drive the transmission ring 6 to rotate forward and backward through the axial forward and backward movement of the dual - purpose shaft 5. The needle - holding rubber sleeve 8 is arranged inside the lower part of the outer housing 4, the holding spring 7 is buried inside the needle - holding rubber sleeve 8, the upper end of the holding spring 7 is connected to the transmission ring 6 through an upper hook, and the lower end of the holding spring 7 is connected to the outer housing 4 through a lower hook. The treatment needle 2 is installed in the inner hole of the needle - holding rubber sleeve 8.

[0029] The above - mentioned dual - purpose shaft 5, transmission ring 6, holding spring 7 and needle - holding rubber sleeve 8 form a set of needle - holding, locking, pushing and releasing mechanism, and its working principle is as follows:

[0030] 1. Insertion of the treatment needle 2: Press the forward movement button 9 once, so that the core rod 3a of the electric push rod 3 and the dual-purpose shaft 5 extend forward by a set length. The forward extension of the dual-purpose shaft 5 drives the transmission ring 6 to rotate forward by a set angle. When the transmission ring 6 rotates forward, it drives the holding spring 7 to twist and expand in the inner diameter direction, thereby expanding the inner hole of the needle-holding rubber sleeve 8. Thus, the treatment needle 2 can be smoothly inserted into the inner hole of the needle-holding rubber sleeve 8. When the tail end of the treatment needle 2 abuts against the front end of the dual-purpose shaft 5, the insertion stops, and the treatment needle 2 is installed in place.

[0031] 2. Fixation of the treatment needle 2: Press the backward movement button 10 once, so that the core rod 3a of the electric push rod 3 and the dual-purpose shaft 5 retract. The retraction of the dual-purpose shaft 5 drives the transmission ring 6 to rotate reversely. When the transmission ring 6 rotates reversely, the holding spring 7 will first automatically reset under its own acting force. The inner diameter of the holding spring 7 shrinks, thereby shrinking the inner hole of the needle-holding rubber sleeve 8 and clamping the treatment needle 2. As the core rod 3a continues to retract, the transmission ring 6 will also continue to rotate reversely, driving the inner diameter of the holding spring 7 to further shrink, and further shrinking the inner hole of the needle-holding rubber sleeve 8, thereby firmly fixing the treatment needle 2.

[0032] 3. Release and replacement of the treatment needle 2: Press the forward movement button 9 again. The core rod 3a of the electric push rod 3 and the dual-purpose shaft 5 extend forward again, driving the transmission ring 6 to rotate forward. When the transmission ring 6 rotates forward, the inner diameter of the holding spring 7 gradually becomes larger, so that the inner hole of the needle-holding rubber sleeve 8 also gradually expands. When the front end of the dual-purpose shaft 5 extends forward to abut against the tail end of the treatment needle 2, the treatment needle 2 is basically loosened and can be pulled out with a little force. If it is still not easy to pull out [the treatment needle 2 may be closely adhered to the needle-holding rubber sleeve 8], the core rod 3a and the dual-purpose shaft 5 can be made to continue to extend forward [continuously press the forward movement button 9 for a certain period of time]. In this way, the needle-holding rubber sleeve 8 will expand further, and the dual-purpose shaft 5 will simultaneously push the treatment needle 2 outwards, and the treatment needle 2 can be smoothly pulled out and inserted. Then release the forward movement button 9, and the core rod 3a of the electric push rod 3 and the dual-purpose shaft 5 will automatically return to the position waiting to insert the treatment needle 2. At this time, insert the selected treatment needle 2. In this embodiment, the electric push rod 3 is powered by a built-in rechargeable battery 11, and the control circuit for controlling the operation of the electric push rod 3 by the forward movement button 9 and the backward movement button 10 can adopt a conventional design in the prior art and will not be elaborated here.

[0033] In this embodiment, three circumferentially evenly distributed limit pins 6a are installed on the outer wall of the transmission ring 6, and an annular groove 4a corresponding to the limit pins 6a is opened on the inner wall of the outer housing 4. The limit pins 6a are movably connected in the annular groove 4a, so that the transmission ring 6 can freely rotate in the outer housing 4 but cannot move axially; a round pin 5a is fixedly installed on the outer wall of the dual-purpose shaft 5, and a spiral groove 6b is opened on the inner surface of the transmission ring 6. The round pin 5a is slidably fitted in the spiral groove 6b, and the round pin 5a and the spiral groove 6b form a direction-changing transmission mechanism.

[0034] In this embodiment, an annular groove 2a with an elastic snap spring 12 is provided at the tail end of the treatment needle 2. The end of the connecting wire of the operating instrument is provided with a plug 13 for connecting to the annular groove 2a. The tip of the plug 13 is provided with a ball head 13a that is snap-fitted with the elastic snap spring 12. A through hole for the plug 13 to penetrate is provided on the side wall of the outer housing 4. With such a setting, after the tail end of the treatment needle 2 is inserted in place, the plug 13 is inserted through the through hole and snap-fitted into the annular groove 2a, and a reliable connection between the treatment needle 2 and the operating instrument can be achieved [positive and negative electrodes can be respectively arranged at the bottom of the elastic snap spring 12 and the annular groove 2a, and positive and negative electrodes can be respectively arranged at the front end and the side wall of the ball head 13a].

[0035] In this embodiment, the treatment needle 2 includes three types: a common needle 2.1, a trephine needle 2.2, and a blunt needle 2.3. Their respective specific structures can be easily replaced, making the clinical functions diverse and scientific.

[0036] The structure of the common needle 2.1 is as Figure 4 shown. It includes a solid needle body 2.1a. An insulating coating 14 is provided on the front surface of the solid needle body 2.1a. The front end of the insulating coating 14 to the tip of the needle is a solid puncture part 2.1b. The common needle 2.1 is used for conventional purposes. The length of the solid puncture part 2.1b is 1 - 3 mm. Clinically, several specifications such as 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, and 3.0 mm can be set for convenient selection and use.

[0037] The structure of the trephine needle 2.2 is as Figure 5 shown. It includes a hollow needle body 2.2a. An insulating coating 14 is provided on the front surface of the hollow needle body 2.2a. A discharge hole 2.2b is provided on the wall of the hollow needle body 2.2a behind the insulating coating 14. The front end of the insulating coating 14 to the tip of the needle is a trephine part 2.2c. A cutting edge is provided at the tip of the trephine part 2.2c. The trephine needle 2.2 is suitable for treating nodular skin lesions, scars, etc. It can simulate CO2 fractional laser. The structural design of the trephine needle 2.2 enables the tissue covered by its tip to be directly removed by trephination [discharged from the discharge hole 2.2b] rather than vaporized. Moreover, the trephine needle 2.2 can also cause thermal stimulation to the surrounding tissue, and thermal stimulation is beneficial to promoting the dissipation or limitation of inflammation, improving blood circulation, enhancing metabolism and the phagocytic function of white blood cells. Thermal stimulation can also reduce the excitability of pain-sensing nerves and accelerate the excretion of pain-causing substances such as histamine. Thermal stimulation of nerve endings can cause reflex vasodilation, increasing the blood flow on the body surface and relatively reducing the congestion of deep tissues. To ensure treatment safety, the inner diameter of the trephine part 2.2c is 1 - 2 mm. Clinically, several specifications such as 1.0 mm, 1.5 mm, and 2.0 mm can be set for convenient selection and use.

[0038] The structure of the trephine needle head 2.2 is as Figure 6 shown. The front end of the blunt needle head 2.3 is flat and no insulation coating 14 is provided on the surface. The blunt needle head 2.3 is suitable for treating flat warts, etc. The diameter of the flat surface at the front end of the blunt needle head 2.3 is 1-2 mm. Clinically, several specifications such as 1.0 mm and 2.0 mm can be set for convenient selection and use.

[0039] The above description only presents the preferred embodiments of the present invention, and the above specific embodiments do not limit the present invention. Within the scope of the technical idea of the present invention, various deformations and modifications can occur. Any retouching, modification or equivalent replacement made by those of ordinary skill in the art based on the above description shall fall within the scope protected by the present invention.
