Description

Light emitting element integrated endoscope clip

Embodiments of the present invention in the surgical endoscope clip, in particular to a self-emitting light emitting diode attached to the light emitting element integrated endoscope clip for easy identification of the location of the affected area during surgery of the patient.

It is very important to determine the exact location of the tumor during the surgery, especially in the removal of a part of the stomach. However, in most cases, since the tumor is operated only on the inner wall of the stomach, the surgeon cannot determine the exact location of the tumor by looking at the external shape or condition of the stomach from the outside. For this reason, the conventional method is to identify the site of the tumor through an endoscope immediately before the patient is operated, and insert a metal clip into the affected area through the passage attached to the endoscope to mark the position, and at the time of surgery, a part of the trachea is removed. Later, a method of determining the result of ablation by checking the position of the clip at the ablation site has been used.

However, this method was only a method of confirming the results after resection of the trachea based on the experience and speculation of the chief physician. Therefore, if the initial resection was not performed correctly, the resection will be performed again. This increases, the longer the operation time and the higher the cost.

One embodiment of the present invention is a light-emitting device that is built into the main body of the endoscope clip and the power supply and control circuit, the light emitting diode attached to the affected area using the endoscope before surgery to flash at regular intervals by mounting a light emitting diode on the attachment surface of the clip Provide an integrated endoscope clip.

In addition, in one embodiment of the present invention, when the brightness of the light emitting diode is above a certain level, the light penetrates the stomach wall and visually identifies the blinking state of the light emitting diode from the outside, so that the point where the clip is mounted is precisely within an error range of several mm. Provided is a light emitting device-integrated endoscope clip.

To achieve the above embodiment, the endoscope clip is a clip portion including a light emitting element; A mount connector for detaching said clip portion from an endoscope when said clip portion is mounted to an object; And a controller configured to apply power to the light emitting device according to the separation.

According to one embodiment of the present invention, the endoscope clip shoots light at the affected part, and during surgery, the gynecologist accurately grasps the affected part to minimize the excision range of the affected part, so that the operation can be ended in a short time without resection.

In addition, according to one embodiment of the present invention, the position of the endoscope clip attached from the outside can be easily confirmed with the eye, it is possible to accurately determine the ablation site during surgery.

In addition, according to an embodiment of the present invention, the surgeon removes only the affected part to prevent unnecessary resection from the patient's point of view, thereby reducing the postoperative recovery period.

In addition, according to one embodiment of the present invention, from the standpoint of the gynecologist has an effect of reducing fatigue by significantly shortening the operation time.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited or limited by the embodiments. Like reference numerals in the drawings denote like elements.

Hereinafter, a light emitting diode integrated endoscope clip according to an embodiment of the present invention will be described with reference to the accompanying drawings.

Referring to Figure 1, the LED integrated endoscope clip according to the present invention flashes the light emitting diode 110, the light emitting diode 110, which is attached to the front of the clip at a predetermined time interval and according to the thickness of the organ to which the clip is attached It includes a control unit 120 for determining the brightness of the light emitting diode 110, a power supply unit 130 for operating the light emitting diode 110 and the control unit 120, a mounting connector 140 used when the clip is mounted using the endoscope. This will be explained.

The light emitting diode 110 is attached to the front surface of the clip and emits light toward the outside of the organ where the clip is fixed so that the surgeon can determine the position of the clip during surgery.

The control unit 120 controls the light to blink at a predetermined interval by adjusting the power supplied to the light emitting diode 110, and the blinking interval of the light flashes in advance by using the connector connector 140 when mounted through the endoscope. Allows you to adjust the spacing. The flashing function of the light provides the following advantages.

Since the light emitting diode 110 occupies most of the current consumption among the components of the present invention, when the light emission period is adjusted by stopping for 10 seconds after emitting 0.1 seconds, the current consumption is reduced to 1/100 compared to continuous lighting. Since the amount of power required by 130 is reduced, it is much more advantageous to downsize and lighten the entire clip.

In the case of the flashing method, as the current consumption is reduced, the heat generation amount of the light emitting diode 110 is also reduced, which greatly increases the stability of the clip.

In the case of the flashing method, since the visibility is higher than the continuous lighting, it is much easier to recognize the position of the clip due to the blinking operation of the light emitting diode 110 of the external collection.

When two or more positions to be operated need to be equipped with a plurality of clips, when inserting them with different flashing periods when inserting them through the endoscope, the external collection of the plurality of clips is much easier to distinguish from each other.

The power supply unit 130 is a power supply device for operating the light emitting diode 110 and the control unit 120, and should be operated until the operation after the clip is mounted through the endoscope, and thus, the power supply unit 130 should have an amount of power capable of operating for 6 to 24 hours.

The mounter connector 140 serves to fix the endoscope mechanism and the clip when the clip is mounted to the affected part using the endoscope.

The power supply unit 130 can be operated in two ways, one method is to supply power using a built-in battery that can be driven by itself, and the other method uses a method using wireless charging.

In the case of using the wireless charging method, only a secondary coil for power reception capable of receiving an induced current without an internal battery is built in, and during operation, a power supply is attached by attaching a charging pad that can be charged to the affected part. In both methods, the battery method is simple in configuration and relatively inexpensive to manufacture, whereas in the wireless charging method, the operation is performed within 24 hours since the size is smaller and the charging pad can be charged at any time. There is an advantage that you do not have to be bound by time.

In addition, since the light-emitting diode integrated endoscope clip of the present invention is a medical device for surgery, it has a stability to the human body, and it is natural to be manufactured in a very small size because it is mounted through an auxiliary passage of the endoscope.

In the endoscope clip of the present invention, an operation step of the light emitting diode is divided into two steps, an initialization step and a flashing step, and operate in the following manner.

In the initializing step (S100), the endoscope operator mounts the clip to the affected part using the mounting machine. At this time, when the mounter connector 140 and the mounter are separated (S110), the switch inside is operated. From this point, power is supplied (S120), and the endoscope clip starts to operate. In addition, when the power is supplied, the control unit 120 is initialized (S130).

In the blinking step (S200), the light emitting diode 110 is turned on (S210) and waits for a lighting time (S220). Afterwards, the light emitting diode 110 is turned off (S230) and waits for a waiting time (S240).

The lighting step S230 and the waiting step S240 may be repeated. For example, in consideration of the power of the power supply unit 130 and visibility of the concentration, the lighting step (S230) and the standby (S240) step, the time to turn on the light emitting diode 110 to 0.1 to 0.3 seconds, the light emitting diode 110 ) Can be repeated in a cycle of 3 to 10 seconds. At this time, the lighting (S230) and the standby (S240) step may be repeated indefinitely until the battery power is exhausted (usually 6 to 24 hours).

In addition, in consideration of the characteristic that the operation is performed 6 to 12 hours after the clip is attached to the endoscope immediately after the clip is mounted, the flashing step (S200) does not repeat the flash unconditionally.

For example, the blinking step (S200) may operate in the following three steps.

1. Initial timer phase: blinks for a certain time to check the normal blinking condition after the first installation (10 minutes),

2. Sleep timer phase: Sleep for a certain period of time (6 hours) in consideration of the operation time.

3. On Timer and Standby Timer Phase: After the sleep time has elapsed, it will change to the active state and repeat the flashing process.

At this time, 10 minutes of the initial timer phase or 6 hours of the sleep timer phase may be arbitrarily adjusted according to the implementation rather than a fixed value.

The mounter connector 140 may be mounted in a state in which a power cap made of a nonconductor such as plastic blocks an electrode of a power terminal until use. For example, in FIG. 5A, an insulator is inserted between the electrodes A and B so that no current flows between the electrodes A and B. FIG.

After use, the connector connector 140 is separated from the power cap, at which time the two electrodes can be connected. For example, as shown in FIG. 5B, when current begins to flow between the electrodes A and B, the connector connector 140 starts the blinking step from this time.

The endoscope clip is provided so that the clip on the front is composed of three legs can be fixed to the affected part.

Referring to FIG. 4, the LED integrated endoscope clip includes a light emitting diode 420 attached to the front surface of the clip 410, a controller 430 for flashing the light emitting diode 420 at predetermined time intervals, and a light emitting diode 420. And a power supply unit 440 for supplying power to the control unit 430, and a mounter connector 450 used when the clip 410 is mounted using the endoscope.

The controller 430 blinks the light emitting diode 420 at a predetermined time interval, and adjusts the brightness of the light emitting diode 420 according to the thickness of the organ to which the clip 410 is attached.

When the mount connector 450 is detached from the mount, the controller 430 operates the lighting timer to turn on the light emitting diode 420 during the lighting time, and the standby timer to operate the light emitting diode 420 during the waiting time after the lighting time. Turn off.

In addition, after the initial installation, the controller 430 operates an initial timer to blink for a preset initial time, and operates a sleep timer to sleep for a preset sleep time in consideration of an operation time. Thereafter, the controller 430 controls the LED 420 to blink by operating a lighting timer for calculating and informing a lighting time and a standby timer for calculating and informing a waiting time.

The display image of the lit state is shown while the light emitting diode is blinking on the opposite side of the tissue of the resected stomach tissue.

In the above description, the above surgery is taken as an example, but the endoscope clip of the present invention is generally applicable to all operations requiring a location indication as well as a digestive organ such as a large intestine and a small intestine.

Referring to FIG. 7, the endoscope clip includes a light emitting element 710 for outputting light, a clip unit 720 mounted to an object, a mount connector 730 for separating the clip unit 720 from the endoscope, and a power supply unit for supplying power. 740, a control unit 750 for applying the power of the power supply unit 740 to the light emitting device 710. In addition, the coil 760 for wireless charging charges the power supply unit 740 with an external power source using a charging pad. Hereinafter, the configuration of such an endoscope clip will be described.

The clip portion 720 includes a light emitting element 710 for outputting light that is distinguished from an object that is a human tissue. When the clip portion 720 is attached to the object, the connector connector 730 is connected to the clip portion 720 from the endoscope. To separate.

When the clip unit 720 is separated from the endoscope, the controller 750 applies the power of the power source unit 740 to the light emitting device 710. The mount connector 730 removes the insulating material inserted between the light emitting device 710 and the power supply 740 when the clip unit 720 is removed, and the control unit 750 removes the insulating material, thereby the power supply unit 740. ) And the light emitting device 710 electrically connected to each other blinks at a predetermined time interval.

The controller 750 determines the luminance by adjusting the current amount of the light emitting device 710 according to the thickness of the object. For example, when the thickness of the object is thick and a brighter brightness is required, the controller 750 may adjust the current amount to the light emitting device 710 to increase.

In addition, the controller 750 optimizes power consumption of the light emitting device 710 by setting a lighting time and a waiting time for the timer, and stops applying power to the light emitting device 710 during the waiting time after the lighting time according to the occurrence of the timer event. do.

The controller 750 may determine the waiting time set in the timer in consideration of the surgery time. In addition, when there are a plurality of clip units 720 mounted on the object, the controller 750 may change the time intervals at which the light emitting device 710 blinks with each of the plurality of clip units 720.

The controller 750 adjusts the amount of power applied to the light emitting device 710 in response to a changing situation according to a surgical condition associated with the endoscope. The control unit 750 operates the sleep timer in response to the surgical condition to adjust the time interval at which the light emitting device 710 flashes after the sleep time elapses to stop supplying power to the light emitting device 710 in accordance with the preparation time for the surgery.
