Description

Laser guide arm for ultra sound guided nerve block and vessel access}

The present invention facilitates the procedure by helping to maintain the entry of the needle into the middle of the blood vessel visible in the ultrasound image during a procedure, examination, or injection using ultrasound in orthopedic and pain medicine departments, or when placing an ultrasound guide tube. It relates to a seeker assistance device for the procedure.

Medical devices are developed and automated day by day, but the injections performed to finally administer drugs depend on the individual's ability and discretion.

Since the orientation including the angle and depth is very important for injections performed by medical personnel, the medical personnel are not skilled, or depending on the patient or the procedure (examination) environment, the syringe needle cannot be poked at the location where it should be entered, or the exact location cannot be found. The mistake of stabbing the needle multiple times can occur.

In addition, the procedure using an ultrasound imaging device is a process in which the position of the needle must be matched with the image that changes according to the movement of both hands while the procedure is performed while holding the syringe with the dominant hand and the ultrasonic probe with the other hand. There is the hassle of having to live.

In addition, although positioning the syringe and needle vertically along the center line virtually for the probe identified by the image is indispensable for the accuracy and success rate of the procedure, the coordination of both hands described above, it is difficult to adjust both hands at the same time while viewing the image. It is not easy to keep the tip of the needle with the back facing the center of the blood vessel accurately on the skin surface.

Accordingly, an injection device that injects an injection drug while checking the state of the injection needle inserted into the lesion site through ultrasound in order to solve the problem that the reliability of the procedure is low, such as the accuracy of the procedure is low and the procedure takes a long time. It has been applied to the Korean Intellectual Property Office and disclosed its technology configuration as Korean Patent Publication No. 10-2018-0027055 (hereinafter referred to as'prior disclosure').

The pre-disclosure relates to a vascular puncture guide device attached to an ultrasonic probe, and more specifically, a probe mounting portion that is directly attached to the ultrasonic probe to fix the ultrasonic probe and is coupled to a side end of the probe mounting portion, and the injection needle is A configuration including an injection needle guide unit that is mounted directly and guides the injection needle to a target blood vessel has been proposed.

In addition, pre-disclosure relates to a vascular puncture system using a vascular puncture guide device attached to an ultrasonic probe, and more specifically, an injection needle inserted into a blood vessel in the skin to which the ultrasonic probe is applied, and attached to the ultrasonic probe, and the injection needle It is characterized in that it comprises a vascular puncture guide device for guiding the blood vessel to be inserted into the blood vessel, and a blood backflow prevention chamber coupled to the injection needle to prevent backflow of blood through the injection needle.

According to the vascular puncture guide device attached to the ultrasonic probe and the vascular puncture system using the same, the needle guide part of the vascular puncture guide device attached to the ultrasonic probe is configured in the form of a forceps, and grips the needle guide part. When pressure is applied, the needle fixing hole is opened, so that the guide device can be easily removed from the needle after the wire is correctly inserted into the blood vessel, so that the vascular puncture can be successfully performed under ultrasonic guidance, and the guide device without shaking. Can be removed, so that the next procedure can be efficiently performed while the injection needle is inserted into the blood vessel.

In addition, according to the preliminary disclosure, in the vascular puncture system, it includes a blood reflux prevention chamber coupled to the injection needle, and allows the wire to be inserted into the injection needle through the blood reflux prevention chamber, so that the wire is effectively inserted into the blood vessel while injecting By preventing the backflow of blood through the needle, unnecessary bleeding and contamination of the surrounding area can be minimized, and as a result, the efficiency of the vascular puncture procedure can be increased.

However, in the pre-disclosure as described above, the injection needle is inserted into the blood vessel through the injection needle guide unit coupled to the ultrasound probe, but if a case in which the injection needle cannot be accurately inserted into the center of the patient's blood vessel occurs during the injection needle insertion process, the already inserted injection needle is removed and When injecting, the position of the needle guide must be adjusted to cause re-injection.

This inconvenience is due to the installation of an injection needle guide unit that guides the insertion of the injection needle into the ultrasonic probe.

In the case of the pre-disclosure, there is a disadvantage in that the shape and size of the needle guide portion are severely limited in the aspect of a syringe or instrument that can be used for a procedure, and thus cannot adapt to various procedures and patient conditions.

In addition, in the case of the guide unit, since it directly contacts the injection needle entering the body, there is a disadvantage that disinfection and aseptic treatment are not practically easy, although sterilization should be maintained.

In particular, the injection site is on a flat surface, but in reality, there are more areas such as the neck or arm with large curvature. In the case of pre-disclosure, there is a disadvantage that the guide portion limits the entry angle of the injection needle to one, so that it is not stable to be applied to a region with a large curvature.

It is a perspective view of an ultrasonic probe to which this is applied.

The present invention is a blood vessel 80 and a nerve search location tracked by an ultrasound diagnostic device that performs a procedure and examination through an image in the skin displayed on a display window of an imaging device using the ultrasound probe 100 in the department of orthopedic surgery and pain medicine. Disclosed is an assistive device for an ultrasound guided procedure that allows a drug to be accurately administered to

According to the accompanying drawings, the present invention moves the ultrasound probe 100 along the skin surface (S) of the affected area to search for blood vessels and nerves to which a practitioner or explorer will administer a therapeutic drug to the lesion site, as shown in FIG. When scanning in the length) direction or in the short axis (cross-section) direction of the tracking blood vessel as shown in FIG. 1B, the tracking blood vessel 80 or nerve that is searched by the patient's affected part scanning operation to the outer surface of the ultrasound probe 100 as shown in FIG. 2 The laser beam member 200 to which the laser beams L1 and L2 are irradiated to the skin surface S of the position is provided.

The laser beam (L1, L2) irradiation of the laser beam member 200 is preferably irradiated in each direction from the outer surface of the housing 110 of the ultrasonic probe 100. A diode 210 is installed, and a second laser diode 230 is installed on the left and right sides orthogonal to the front surface of the housing 110.

The laser beams L1 and L2 irradiated in the forward direction from the first laser diode 210 and the second laser diode 230 installed on the front, left and right sides of the housing 110, respectively, are applied to the skin surface (S) of the affected area. ) In a straight line.

Electric signals are transmitted and received in the same direction as the laser beams L1 and L2 irradiating the skin at a position below the first and second laser diodes 210 and 230 installed on the outer surface of the housing 110 of the ultrasonic probe 100 As a result, a light emitting member 300 is installed that senses whether the injection needle 95 and the syringe 90 are placed in accord with each other.

In the installation of the light emitting member 300, it is preferable to be installed at the lower position of the first diode 210 and the second diode 230, in the first and second laser diodes (210, 230) A detection sensor 330 that senses whether the injection needle 95 and the syringe 90 are placed on the line of the irradiated laser beams L1 and L2, and the injection needle 95 is connected to the detection sensor 330. ) Is composed of first and second LEDs 310 and 320 in which green or red light is turned on and off depending on whether or not the line of the laser beams L1 and L2 is matched.

In addition, the light emitting member 300 is to be further provided with an alarm body 420 that generates an alarm sound at the same time when the green light of the first and second LEDs 310 and 320 is turned off and the red light is turned on. desirable.

The detection sensor 330 allows an electrical signal to be transmitted in a parallel direction with respect to the laser beam irradiated to the skin surface (S), and the transmitted electrical signal is reflected back by hitting a reflective piece searched on a syringe or needle. By receiving a signal, it is configured as a closed circuit that determines whether the injection needle 95 and the syringe 90 are placed in line with the lines of the laser beams L1 and L2, and causes an alarm sound to sound from the alarm body 420.

The ultrasonic probe 100, the laser beam member 200, and the light emitting member 300 are connected to a driving control member 400 installed in the housing 110 to control driving of an electrical circuit.

3 is a view showing the state of the operator's hand during the ultrasound probe search and injection operation of the present invention. The ultrasound probe 100 held by the operator with one hand is in close contact with the skin surface (S) at the lesion location of the patient in various directions. When rotating and moving, blood vessels and nerves can be seen on the display window of an imaging device (not shown). Therefore, the operator carefully tracks the blood vessels and nerve positions seen through the screen to determine the tracking vessel 80 and nerve positions, and at the same time, In the laser member 200 of the ultrasonic probe 100, the driving member 400 is turned "on" so that the laser beams L1 and L2 are irradiated.

At this time, the operator adjusts so that the injection needle 95 or the syringe 90 including the injection needle are aligned in a straight line at the line position of the laser beams L1 and L2 while holding the syringe with the other hand.

When the injection needle 95 or the syringe 90 including the injection needle are placed in line with the laser beams (L1, L2) irradiated to the skin surface (S) of the lesion area, the detection sensor 330 of the light emitting member 300 When it is determined that the reflected signal is received, green light is turned on in the first and second LEDs 310 and 320.

In addition, when the injection needle 95 or the syringe 90 including the injection needle is out of the laser beam line position at the line position of the laser beams L1 and L2, the reflection signal is not received by the detection sensor 330. , As the green light is turned off in the second LEDs 310 and 320 and the red light is turned on at the same time, the driving member 400 is driven so that an alarm sound is sounded in the alarm body 420.

In addition, when the injection needle 95 or the syringe 90 including the injection needle is out of the laser beam line position at the line position of the laser beams L1 and L2, the reflection signal is not received by the detection sensor 330. , As the green light is turned off in the second LEDs 310 and 320 and the red light is turned on at the same time, the driving member 400 is driven so that an alarm sound is sounded in the alarm body 420. This is possible by a configuration in which a reflective piece through which an electric signal transmitted from the detection sensor is reflected when the injection needle is placed in line with the line of the laser beam is provided at the injection needle coupling position of the syringe.

Since the alarm sound from the alarm body 420 is an audible display indicating that the injection needle 95 or the syringe 90 is not matched at the line position of the laser beams L1 and L2, the operator should have the injection needle 95 Recognizing that it is not possible to accurately enter the tracked blood vessel center position, the tip of the needle 95 is reset to a position that can accurately enter the tracked blood vessel 80 center position, but only when positioning is confirmed. After that, you can adjust the setting position while looking at the screen of the imaging device.

If the injection needle 950 that deviates from the line of the laser beam (L1, L2) irradiated on the skin surface (S) of the lesion area is matched with the line of the laser beam again, the red light turns off and the green light turns on and the alarm body 420 The alarm sound is also turned off.

However, even though the position is adjusted, if the needle 95 is not placed in a position coincident with the line of the laser beams L1 and L2, the first and second LEDs 310 and 320 are again lit with red light, and at the same time, the alarm body 420 Since the driving of the “non-matching state” that sounds an alarm is activated, the operator repeatedly checks until the tip of the needle 95 coincides with the line of the laser beam (L1, L2).

After that, the explorer or the operator sets the position of the injection needle 95 to match the laser beam (L1, L2) line while looking at the tracking vessel 80 seen through the screen of the imaging device, the alarm sound and red light are terminated and the green light is turned off. Since it is turned on, it is recognized that the injection needle 95 matches the tracking blood vessel 80, so that the syringe 90 is pushed toward the tracking blood vessel 80.

In this way, the syringe needle 95 is safely and accurately entered to the target point toward the central position of the tracking vessel 80, and the filled therapeutic drug is injected to the target point by pressing the handle of the syringe rod in the entered state.

In the present invention, an alarm sound and green light and red light are repeatedly driven until the injection needle or the syringe including the injection needle is aligned in a straight line on the laser beam line projected on the skin at the tracked blood vessel location, so that the operator can Visually as well as aurally, it makes it possible to judge that the needle and the syringe match the laser beam line, and helps the operator to determine that it is safe to inject the needle, as well as safely setting the injection position and making an accurate target. The ability to administer therapeutic drugs to the point of view improves the reliability of the procedure for both the operator and the patient.

The cover body 150 has a locking protrusion 153 for maintaining a state mounted on the outer surface of the housing 110 is formed at the lower end of the coupling hole 151 to be coupled to the lower end of the housing 110. do.

The first and second laser diodes are irradiated to the outer surface of the cover body 110 in the front direction of the housing 110 to illuminate the horizontal and vertical directions of the skin surface S. A laser beam member 200 made of (210, 230) is provided.

A light emitting member 300 is provided at a position adjacent to the laser beam member 200 to determine whether the injection needle is properly placed at the injection position and to notify the operator.

The light-emitting member 300 is installed at a lower position of the first and second laser diodes 210 and 230 and is irradiated to the skin surface S and a syringe 90 filled with a treatment drug and a laser beam L1 and L2. And a detection sensor 330 for detecting whether the injection needle 95 matches, and an injection needle installed around the first and second laser diodes 210 and 230 to irradiate the skin with a laser beam line ( 95) and the first LED 310 and the second LED 320 emitting green light or red light according to the determination of the detection sensor 330 that detects whether the syringe 90 including the injection needle is placed in a coincident manner. Done.

In addition, a driving control member 400 for organically determining whether the laser beam member 200 and the light emitting member 300 are in a driving state is provided in the accommodation chamber protruding toward the side of the cover body 150.

The driving control member 400 includes a driving circuit unit 410 in which the laser beam member 200 and the light emitting member 300 are connected to each other through an electrical circuit to operate in a programmed state, and the driving circuit unit 410 Thus, the detection sensor 330 is formed as an alarm body 420 that sounds an alarm when a state in which the injection needle 95 does not coincide with the lines of the laser beams L1 and L2 is detected, and the driving circuit part 410 has A control switch 430 for controlling power supplied to the laser beam member 200 and the light emitting member 300 is provided to form a closed circuit.

FIG. 7 is a longitudinal section of the ultrasound probe in the applied state of FIG. 6, showing a tracking blood vessel search state at the lesion site, wherein the searcher or the operator and the searcher hold the housing 110 of the ultrasound probe 100 with one hand. As shown in the figure, when scanning is performed by contacting the affected area in the same state as in a normal ultrasound procedure, the searched skin internal structure of the lesion area is displayed on the screen of the image display. When the control switch 430 of the driving circuit part 410 is turned "on" while being positioned on the skin surface S, the first and second laser diodes 210 and 230 of the laser beam member 200 (L1, L2) are simultaneously irradiated in the horizontal and vertical directions from the front of the housing 110 so that the laser beam (L1) in the long axis direction of the tracking blood vessel and the laser beam (L2) in the short axis direction of the blood vessel ( It is reflected in S).

In other words, the operator moves the housing 110 of the ultrasound probe 100 with one hand, and adjusts the tracking vessel 80, which is searched by the patient's arm (the lesion area), to be displayed in the long axis, that is, the longitudinal direction on the image device screen. When the laser beam (L1) of the first laser diode 210 irradiated to the front of the housing 110 is irradiated to the skin surface (S) where the tracking blood vessel 80 is located, the tracking blood vessel shown on the screen ( 80) and the laser beam L1 projected on the skin surface S are in a matched state.

When the line of the laser beam (L1) is irradiated horizontally with respect to the skin surface (S) of the arm, the tracking blood vessel 80 is displayed in the longitudinal direction. 2 The laser beam L2 irradiated from the laser diode 230 is in a state to illuminate the cross section of the tracking blood vessel 80 in the vertical direction.

As described above, in the process of searching the tracking vessel 80 by moving the ultrasound probe 100 with one hand, the searcher or the operator manipulates the housing 10 when the tracking vessel 80 is found, so that the laser beams L1 and L2 In other words, the laser beams (L1, L2) that are irradiated to the skin surface (S) of the lesion area indicate the location of the tracking vessel 80, and the operator has a laser at the center of the tracking vessel. In order to accurately irradiate the beam, the screen of the image display is continuously looked at while holding the housing 110.

At this time, hold the syringe 90 filled with the treatment drug with the other hand, and the tip of the injection needle 95 coincides with the long axis or short axis laser beam (L1, L2) line projected on the skin surface (S). Set the location as much as possible.

When setting the position so that the tip of the needle 95 coincides with the line of the laser beams (L1, L2) that are illuminated, the driving control is initially made because the needle 95 is out of the position coincident with the line of the laser beam (). Since the electrical signal transmitted from the detection sensor 330 of the member 400 is not reflected and received, a red light is turned on and an alarm sound is sounded.

However, when the syringe 90 or the needle 5 reaches a position corresponding to the line of the laser beams L1 and L2 irradiated to the skin surface S, the electrical signal transmitted from the detection sensor 330 is transmitted to the syringe. (90) or through the reflective surface of the injection needle 95, the state is reflected and received by the detection sensor 330, so that the light emission states of the first and second LEDs 310 and 320, which have been red so far, are converted into green light. The alarm sound of the alarm body 420 is short-circuited.

As a result, the operator who mainly watches the screen of the imaging device recognizes that the injection needle 95 and the syringe 90 are accurately placed at the tracking vessel 80 or the nerve site because the alarm sound is short-circuited. This can also be recognized by the green light of the first and second LEDs 310 and 320 of the detection sensor 330, which turns off the red light together with the short circuit of the alarm sound and turns on at the same time.

In this way, a searcher and a practitioner hold the ultrasound probe 100 with one hand and conduct a blood vessel search operation and apply the laser beams L1 and L2 to the skin surface S at the location of the searched blood vessel and nerve area while viewing the search image. It is controlled to illuminate the center position of the tracking blood vessel 80 by irradiation, and the other hand holds the syringe 90 and sets the tip of the injection needle 95 to match the laser beam line illuminating the blood vessel position. It can be set easily.

By whether or not the reflection of the sensing signal of the light-emitting member 300 is received or not and the light and sound driving in the driving control member 400 interlocked therewith, the practitioner agrees that the injection needle 95 deviates from the center of the tracking blood vessel 80. Since it is recognized even when looking at only the screen that the position is in a position that does not match or is in the same position, the operator immediately moves the syringe 90 or the needle 95 to the position of the tracking vessel 80 as the alarm sound is activated and short-circuited. It can be reset to.

In particular, the alarm driving state in the driving member 400 is a state in which the injection needle 95 is directed toward the tracking blood vessel 80 through the laser beams L1 and L2 even when the operator keeps looking at the screen of the imaging device. As it can be maintained, the injection needle 95 not only accurately enters the central location of the tracking blood vessel 80 or the nerve area, but also serves as a guide to reach the central location of the tracking blood vessel 80 or the target point of the nerve area. It will be possible to inject drugs accurately.
