There is an effect that can be completely blocked. This is an innovative improvement over the dampers used in conventional ultrasonic probes.

8 is a flowchart of a method of manufacturing a damper for a 3-D ultrasonic probe according to an embodiment of the present invention. As shown in FIG. 8, in the method of manufacturing a damper for a 3-D ultrasonic probe according to an exemplary embodiment of the present invention, a three-dimensional image is obtained by swinging an array axis of a plurality of first-order ultrasonic transceiver elements at a predetermined angle. In the manufacturing method of the damper for storing the oil to be supplied to the ultrasonic module for transmitting and receiving the ultrasonic wave to transmit and receive the ultrasonic probe, the step of cutting a rectangular damper sheet of at least one side is thermally compressed (S100), for the damper Forming an M-shaped folded portion on one side by bending the sheet a plurality of times (S200), heating and pressing both ends of the M-shaped folded portion (S300), and heat-pressing and sealing the other side on which the M-shaped folded portion is not formed Step to produce an oil storage tube (S400), cutting a predetermined portion of both ends of the oil storage tube (S500), cutting a wing end of a pair of spouts In step S600, the spouts may be attached to both ends of the oil storage tube, respectively, to complete the damper (S700).

In step S100, the rectangular damper sheet which at least one side was thermally crimped is cut out. In this case, the damper sheet, as mentioned above, may be a mixture of nylon (Nylon) and LLDPE (Linear Low-density Polyethylene), and the horizontal and vertical 20 to 40 cm (more specifically, horizontal 30 cm, vertical 34 cm). The cutting of the damper sheet will be described in more detail with reference to FIG. 9.

9 is a view showing a process of step S100 of the manufacturing method of the damper for 3-D ultrasonic probe according to an embodiment of the present invention. Cutting the damper sheet is to allow the damper to be installed inside the ultrasonic probe, as shown in Figure 9, the step of the manufacturing method of the damper for 3-D ultrasonic probe according to an embodiment of the present invention In S100, the damper sheet can be cut into 1/4 size by cutting up, down, left and right. That is, when one damper sheet is cut in step S100, a total of four quarter-size damper sheets can be obtained. In this case, the damper sheet having a size of 1/4 is made of one damper, and the damper sheet may be thermally compressed at least one side thereof.

In step S200, the damper sheet is bent a plurality of times to form an M-shaped folded portion 111 on one side. More specifically, the one side of the heat-compressed side is bent at the top, and the center portion of the damper sheet is bent horizontally once, and then the horizontally bent positions are spaced apart by a predetermined distance from the center portion to the upper or lower direction, respectively. As a result, the M-shaped folded portion 111 can be formed. At this time, the distance from the center portion may be 3mm, M-shaped folded portion 111 will be described in more detail with reference to FIG.

10 is a view showing a process of step S200 of the manufacturing method of the damper for 3-D ultrasonic probe according to an embodiment of the present invention. As shown in FIG. 10, the M-shaped folded portion 111 formed through the step S200 of the method of manufacturing the damper for the 3-D ultrasonic probe according to the exemplary embodiment of the present invention is folded according to the contraction or expansion of the oil. By varying the degree, oil leakage can be prevented.

In step S300, both ends of the M-shaped folded portion 111 are heated and compressed. The pressing process is to maintain the shape of the M-shaped folded portion 111 formed by bending in step S200, and to heat only both ends is to prevent the coating of the damper sheet from being damaged by heat. .

In step S400, the oil storage tube 110 is manufactured by heat-pressing and sealing the other side on which the M-shaped folded portion 111 is not formed. Since the other side where the M-shaped folded portion 111 is not formed is in an open state, the damper that is rough until step S300 does not play a role of storing oil at all. Therefore, by pressing the opposite side in step S400, it is possible to complete the production of the oil storage tube (110). Of course, since the top and bottom of the oil storage tube 110 is still open, by attaching the spout 120 in step S600 it can ensure the sealing performance.

In step S500, a predetermined portion of both ends of the oil storage tube 110 is cut. The step S500 will be described in more detail with reference to FIG. 11.

11 is a view showing a process of step S500 of the manufacturing method of the damper for 3-D ultrasonic probe according to an embodiment of the present invention. As shown in Figure 11, in step S500 of the manufacturing method of the damper for 3-D ultrasonic probe according to an embodiment of the present invention, both ends of the oil storage tube 110 is cut, at this time a predetermined portion is cut 0.5 cm from the end. This is to remove the portion pressed in step S300, so that the spout 120 can be smoothly inserted into the end of the oil storage tube (110).

In step S600, the ends of the blades 122 of the pair of spouts 120 are cut. As described above, the spout 120 has wings 122 for preventing leakage on both sides, and since the ends of the wings 122 are very thin, the ends of the wings 122 of the spout 120 are not removed. When the oil storage tube 110 is attached to the oil storage tube 110 without being inserted, a gap may occur at the tip of the wing 122 of the spout 120 while the oil storage tube 110 is inflated, thereby leaking oil. Therefore, in step S600, a part of the tip of the spout 120 blade 122 may be cut, and specifically, 0.5 to 2 mm (1 mm in one embodiment) may be cut from the tip of the blade 122.

In step S700, the spouts 120 are attached to both ends of the oil storage tube 110 to complete the dampers. The step S700 will be described in more detail with reference to FIG. 12.

12 is a view showing a process of step S700 of the manufacturing method of the damper for 3-D ultrasonic probe according to an embodiment of the present invention. As shown in Figure 12, in step S700 of the manufacturing method of the damper for 3-D ultrasonic probe according to an embodiment of the present invention, after fixing the oil storage tube 110 to cover a portion of the spout 120 Heat and pressure may be applied to couple the spout 120 to the oil storage tube 110.
