It can solve the grievances that medical personnel have been having as an assistant device for accurate insertion of a syringe needle or a biopsy needle at the time of an operation using an ultrasonic probe, inspection or injection.

First, it is safe. For example, the probe support directly supports and secures the transducer located underneath the ultrasonic probe, thereby ensuring the stability with respect to the mounting. At this time, since the probe support is not easily deformed, the safety can be further improved. As another example, it is possible to improve the stability by preventing the angular rail from separating and shaking when adjusting the angle.

Second, the operation is convenient. The existing ultrasonic probe can be used as it is, so that the usability is increased because there is no need to purchase a separate ultrasonic probe suitable for the auxiliary device.

For example, by applying a structure such as a plurality of grooves and a latching jaw to the angle rail mechanism for adjusting the angle, it is possible to increase precision in control. In addition, it is easy to secure the insertion angle of the syringe needle. In the past, when the ultrasonic procedure was used to perform a puncture procedure or a biopsy or injection, if a syringe needle could not be seen in the tissue, the assistant apparatus of the present invention could insert an accurate syringe needle at a position determined from the ultrasound image So that the procedure time can be shortened.

Fourth, miniaturization. By using movable rails instead of fixed rails for angle adjustment, it is possible to reduce the volume when adjusting the angle. As another example, when using an angle adjustment holder instead of an angle rail, the angle rails and angular adjustments become unnecessary and volume is reduced. Volume reduction is associated with reduced manufacturing costs and ease of operation.

The present invention can be used in the treatment of musculoskeletal pain and ultrasonography. The accuracy of existing guided ultrasound procedures can be increased to reduce patient pain, hemorrhage, and inaccuracy.

The scanning assistant device 1 is a device for detachably attaching the ultrasonic probe 2 and the syringe 3 and guiding the ultrasonic probe 2 and the syringe 3 to perform precise scanning with target area monitoring. For example, the medical person may monitor the target area using the ultrasonic probe 2 mounted on the scanning assist device 1 with one hand, while simultaneously monitoring the target area using the ultrasonic probe 2 mounted on the scanning assist device 1 The needle is inserted into the target area and is performed. The scanning assistant device 1 stably fixes the ultrasonic probe 2 and precisely controls the scanning depth and angle so that accurate and easy scanning can be performed.

The ultrasonic probe 2 includes a housing 21 in the form of a body serving as a handle and a transducer 22 provided at the lower end of the housing 21. [ The first probe support 11 fixes and supports the transducer 22 and the second probe support 12 fixes and supports the housing 21. The fixing and supporting can be performed while the ultrasonic probe 2 is wrapped around the outside, and the target area can be monitored in a state where the ultrasonic probe 2 is stably supported. The ultrasonic probe 2 transmits an image signal to a monitor device while being connected to a monitor device (not shown) so that an image is displayed, thereby enabling visual identification and detection of an internal lesion.

The transducer 22 irradiates an ultrasonic wave and converts the reflected ultrasonic wave into an electric signal. Although not shown in detail in order to simplify the illustration, the transducer 22 includes a piezoelectric layer for converting a piezoelectric material into an electrical signal and an acoustic signal while vibrating, a piezoelectric layer for transmitting ultrasound signals generated in the piezoelectric layer to a subject as much as possible A matching layer for reducing the acoustic impedance difference between the piezoelectric layer and the object to be inspected, and a sound-absorbing layer for preventing image distortion by blocking the ultrasonic waves from propagating rearward of the piezoelectric layer. Since the structure and function of the transducer are widely known, a detailed description thereof will be omitted. The first probe support 11 according to the present invention fixes and supports the transducer 22 of the ultrasonic probe 2 so that the ultrasonic probe 2 can be more stably fixed.

The depth rails 13 are fixedly formed in the longitudinal direction of the ultrasonic probe 2 between the first probe support 11 and the second probe support 12. [ The depth rail 13 may be formed in the form of, for example, two rods. The depth adjusting unit 14 is rotatably coupled to the depth rail 13 and adjusts the scanning depth as it moves up and down. For example, the scanning depth can be adjusted within 1 to 4 cm. When the depth adjusting portion 14 has at least one hole, the depth rail 13 may be inserted into the hole.

The depth adjusting unit 14 may use a button for adjusting the depth. For example, when the depth rail button 140 formed on one side of the depth adjusting part 14 is pressed, the depth adjusting part 14 is movable up and down along the depth rail 13.

When the angle is adjusted, it serves to fix the angle rail. The angle rails 16 are formed in an arc shape passing through the angle adjusting portion 15 and are slidably moved or fixed along the longitudinal direction. The angle of entry of the needle into the needle can be adjusted according to the rotation of the angle rail 16 in the angle adjuster 15. For example, the entry angle of the needle can be adjusted within 37.5 to 60 degrees.

The syringe holder 17 is attached to one side of the angle rail 16, on which the syringe 3 is mounted and fixed. The syringe 3 may be mounted or detachable to the syringe holder 17, and the syringe capacity may vary. For example, a 3 ml, 5 ml syringe may be replaced and attached to the syringe holder 17, but this is not intended to be limiting.

In addition, the first probe support base 11 has a structure that is not easily deformed, thereby enhancing safety. At this time, the previously used ultrasonic probe 2 can be used as it is. It is necessary to purchase and use a separate ultrasonic probe having a shape suitable for the scan assist device without using the conventional ultrasonic probe depending on the structure of the scan assist device. According to the present invention, since the existing ultrasonic probe 2 can be used as it is, Is increased. The first probe support 11 may be a plurality of the first probe support 11 to match the size and the shape of the corresponding ultrasonic probe 2 because the medical person can use an ultrasonic probe having a different size and shape according to the treatment environment. Therefore, it is possible to replace the first probe support 11 and / or the second probe support 12 according to the standard of the ultrasonic probe 2 to be used, if necessary. To replace the support, the scanning assistant device 1 may further include a support member detachable member (not shown).
