As the step motors 23 and 33, which are proportional to the number and have a small angle error per step, are easily applied, respectively, the insertion depth of the needle can be easily adjusted. Since no configuration is necessary, the overall configuration becomes simpler and the overall weight can be significantly reduced.

The battery 40 is detachably embedded in the handle of the main body 10, and the battery 40 is charged by supplying power to the aforementioned syringe transfer means 20 and the piston transfer means 30. It is desirable to form as small lithium ion batteries as possible. According to the embodiment, it may be formed of various rechargeable batteries.

Due to the configuration of the battery 40, the need for a separate power line connection can be significantly increased portability and ease of use.

The control and display means 50 is installed on the back side of the main body 10, and the control and display means 50 controls and displays the operation of the above-described syringe transfer means 20 and the piston transfer means 30. By doing so, the control variable selection dial 51 for selecting the control variable of the syringe transfer means 20 and the piston transfer means 30, and is installed on one side of the control variable selection dial 51, the syringe transfer means 20 And a control variable adjusting dial 53 for selecting or adjusting an operation mode according to the selected control variable of the piston transfer means 30 and the rotation angles of the dials 51 and 53 continuously. It controls the operation of the syringe transfer means 20 and the piston transfer means 30 to be operated in an operating mode, where the operating mode corresponds to the number of injections, syringes, and shots corresponding to the rotation angles of the dials 51 and 53.

The control variable selection dial 51 generates a predetermined control signal according to the rotation angle, and serves to operate the above-described syringe transfer means 20 and the piston transfer means 30 in a predetermined operation mode.

The control variable adjusting dial 53 serves to fine-tune the control variable, i.e., the selected variable, the number of injections, the syringe, the injection amount and the depth of injection.

In addition, the control panel 55 is a printed circuit board designed to receive the control signal by the dials 51, 53 to operate the above-described syringe transfer means 20 and the piston transfer means 30 in a predetermined control mode. It consists of.

The operation modes set by the selection dial 51 and the adjustment dial 53 described above are Juvederm Mode, Botox Mode, Apitoxin Mode, and PPP Mode. , Semi PPP Mode, Napage Mode, Etc 1 Mode, Etc 2 Mode, etc. Control variables such as the number of times, injection amount per injection, and injection depth. In particular, in the case of PPP mode, the needle is inserted into a part of the skin, and the drug is continuously injected while the operation switch 13 is pressed, and the drug injection is stopped when the operation switch 13 is released. . In other words, when the operation switch is ON, the syringe moves forward and the needle is inserted into the skin and the piston moves forward and the drug is injected.When the operation switch is OFF, the piston moves backward and the syringe moves backward and simultaneously, the drug is not injected. In the Napage mode, the syringe moves forward while the operating switch (13) is pressed, the needle is inserted into the skin, the piston moves forward, the prescribed drug is injected, and the piston moves backward. The reverse operation is repeated continuously. Micro Mode is an operation mode in which a small amount of drug is injected continuously when the operation switch is pressed and stopped by pressing the operation switch once again.

These operating modes can be continuously developed, in the case of the automatic scanning device 1 according to the present invention by connecting the data cable to the connector connecting portion 15 to update the program for the operating mode in the control panel 55, The developed modes of operation can be easily added and applied to automatic scanning operations.

In addition, the control panel 55 reversely rotates the second step motor 33 of the piston transfer means 30 before the first step motor 23 of the syringe transfer means 20 before the needle exits the skin. It is preferable that the injection liquid contained in the syringe 3 is reduced so as not to flow out. When the needle comes out of the skin, the syringe 3 and the piston 5 are reversed by the syringe transfer means 20 and the piston transfer means 30. In this case, the syringe is driven by the pressure exerted by the piston 5. (3) Since the injection liquid can be discharged by the pressure inside, the first step motor 23 of the main piston transfer means 30 is further reversed to remove the internal pressure in the syringe 3 so as to be accommodated in the syringe 3. Do not spill the injection.

In this case, the syringe holding means 11a for holding the syringe 3 is preferably provided on the front side of the syringe support 11, which is a piston when the needle is pulled out of the skin. The position of the syringe 3 relative to the movement of the piston 5 when the second step motor 33 of the transfer means 30 is reversed before the first step motor 23 of the syringe transfer means 20. By fixing it, the internal pressure in the syringe 3 can be easily removed.

The syringe holding means (11a) may be formed of a screw coupling hole interposed between the syringe 3 and the needle, or may be configured in the gripper form for holding the rear end of the needle.

As shown in FIG. 6, the control variable adjustment dial 51 Rotate () to select the control variable, then the control variable selection indicator lamp is lit. Then, select the mode by rotating the dial to become the mode to set the control variable adjusting dial (53) or the value to be set. Set numerical values. For example, when selecting the operation mode by rotating the control variable selection dial 51, the lamp corresponding to the mode is turned on, and then rotating the control variable adjustment dial 53 to the desired operation mode (napaju). Will be adjusted. Although the values such as the insertion depth, the speed of injection, and the amount of drug injection are set for each operation mode, the control variable selection dial 51 can be used to select the control variable to be changed arbitrarily. Can be easily changed by rotating the dial to the desired value.

When the operation switch 13 is pressed against the tip of the procedure, the syringe transfer means 20, 20 'and the piston transfer means 30 are operated in accordance with a predetermined operation mode under the control of the control panel 63.

In other words, the first lead screw 25 is rotated according to the forward and reverse rotation of the first step motor 23, and the support holder coupled to the syringe support 11 is rotated as the first lead screw 25 rotates. 27 is moved forward and backward along the first lead screw 25, the syringe support 11 is moved forward or backward, or the cylindrical cam 25 'is rotated in accordance with the rotation of the motor 23', the cylindrical cam ( As the 25 ') rotates, the support holder 27 coupled to the syringe support 11 moves along the closed curve groove 25a' formed on the outer circumferential surface of the cylindrical cam 25 ', thereby moving the syringe support 11 forward and backward. The needle is moved back and forth into the treatment area.

At the same time, the second lead screw 35 is rotated in accordance with the forward and reverse rotation of the second step motor 33, and the piston holder 37 coupled to the piston 5 is rotated as the second lead screw 35 rotates. By moving the piston 5 forward and backward along the second lead screw 35 so that the piston 5 is properly moved forward and backward with respect to the syringe 3, the injection liquid in the syringe 3 is injected into the procedure site when the syringe support 11 is advanced. Will be.

In particular, as the second step motor 33 is reversely rotated before the first step motor 23 just before the needle exits the skin, it is preferable to prevent the injection liquid contained in the syringe 3 from flowing out.

In addition, the operator can control the operation of the automatic scanning device 1 according to the present invention while checking the current operating mode through the display panel 57, in the state of stopping the operation through the operation switch (13) Another operation mode may be set by the dials 51 and 53.

In addition, by connecting the data cable to the connector connection portion 15 to update the program relating to the operation mode in the control panel 55, the newly developed operation modes can be easily added and applied to the automatic scanning operation.
