Description

Laparoscopic surgical endoscope module with coating layer applied

The present invention relates to a laparoscopic surgical endoscope module to which a coating layer is applied. More specifically, the endoscope used for laparoscopic surgery is equipped with a camera module and an external module, so that 6-axis movement is possible as intended by the operator, and the use of a fisheye lens and a wide-angle lens provides a wide endoscopic environment, and a coating layer is applied. It relates to a laparoscopic surgical endoscope module to which a coating layer that allows the use of is applied.

Laparoscopic surgery is a surgical method in which a small hole is made in the abdominal layer, inflated for easy observation, and then examined, operated, and tissue is collected or treated while looking inside the abdominal cavity.

Due to the recent development of laparoscopic surgery, unlike open surgery, the size of the incision is small, so the surgical wound is aesthetically pleasing and the pain caused by the wound is much less.

In addition, since it shows a fast recovery rate, the hospital stay period is shorter than that of open surgery, and it has the advantages of being able to quickly return to daily life.

Due to these advantages, it is used in various medical fields such as obstetrics and gynecology, neurosurgery, general surgery and urology.

However, there is a shortage of specialists who assist in laparoscopic camera adjustment during laparoscopic surgery, and nursing personnel are replacing them.

In particular, even if expensive robotic surgical instruments such as Da Vinci are introduced, the installation and adjustment manpower for the camera is required.

Therefore, there is a need for a laparoscopic endoscope module capable of solving the problem of shortage of medical staff and surgical assistant nursing personnel at the laparoscopic surgery site, and capable of adjusting the endoscope camera according to the intention of the operator.

On the other hand, the objective lens of the endoscope is sometimes contaminated during surgical procedures. Tissue particles, blood, mucus, and other bodily fluids adhere to the lens and interfere with vision. When this problem occurs, the usual routine is to remove the endoscope from the patient's body, wash its distal end (lens) with sterile distilled water, wipe the lens with a sterile towel, and reload the laparoscope into the patient's body through a conventional laparoscopic trocar. is to insert During some surgical procedures, the endoscope must be removed frequently to have the lenses wiped clean.

Loss of field of view due to contamination of the objective lens of the endoscope can be a serious problem, especially if it occurs at critical moments during surgery. This increases the time for the procedure and necessitates repeated withdrawal and insertion of the endoscope, which can create trauma to the tissue. The covering of the objective of the endoscope with blood is sometimes referred to as a “red video” signal. This is especially serious when bleeding is heavy and time is spent in removal, cleaning and reinsertion of the lens. If a clean, undisturbed lens is not available quickly enough for identification and control of the source of bleeding, it is likely to transition to an emergency "open" procedure requiring a major surgical incision. Accordingly, various efforts have been made to maintain an uncontaminated objective lens.

An object of the present invention is to provide a laparoscopic surgical endoscope module to which a coating layer is applied so that the coating layer can minimize the problem caused by lens contamination during laparoscopic surgery using a lens.

Embodiments of the present invention will be described in detail so that those of ordinary skill in the art can easily carry out the present invention. However, the present invention may be embodied in several different forms and is not limited to the embodiments described herein.

In the entire application, when a certain part "includes" a certain element, it means that other elements may be further included, rather than excluding other elements, unless specifically stated to the contrary. In addition, terms such as "...unit" and "module" described in the specification mean a unit that processes at least one function or operation, which may be implemented as hardware or software, or a combination of hardware and software. .

The laparoscopic endoscope module according to the present invention includes a clamp unit 100 , an endoscope unit 200 , and a display unit 300 .

First, the tongs 100 will be described with reference to FIG. 1 .

The forceps 100 is configured to be inserted into the abdominal cavity. The forceps 100 serves to hold a needle or thread through which a thread for suturing the surgical site is sewn.

More specifically, the forceps 100 is inserted into the abdominal cavity to suture the surgical site or to remove the lesion (S), and to suture the area from which the lesion (S) has been removed, hold a needle or thread suture will be performed.

Here, as shown in FIG. 1, the end portion (not shown) of the forceps 100 for operating the surgical site in order to suture the surgical site or remove the lesion (S) is made of a hook or forceps shape. have.

This is because it is a suitable form for suturing the surgical site or removing the lesion (S). Here, it may be used in various forms depending on the operator without being limited to the shape of the hook or forceps.

In addition, the forceps 100 can remove the lesion S or easily hold a needle or thread while repeating the closing and opening actions by operating the handle part (not shown in the figure) using the operator's hand.

In addition, the thread or needle can be pulled using the tongs 100 and the lesion (S) can be removed and taken out of the abdominal cavity.

In addition, the forceps 100 is required to have a certain length due to the structure to be inserted into the abdominal cavity. Therefore, it is preferable to have a length of the tongs 100 to facilitate surgery without being limited in length in the abdominal cavity by having a constant length.

Therefore, since the forceps 100 makes a small hole in the abdominal cavity and holds a thread and a suturing device to suture the surgical site or remove the lesion (S) without the need to open the abdominal cavity, the operation time is reduced. , it has the advantage that it can be safely sutured to the abdominal wall without open wounds.

In addition, the forceps 100 may include a high-frequency device using a laser for dissolution of myoma and various treatments, rather than a composition of forceps for suturing the lesion, and various known devices for laparoscopic surgery may be used.

Next, the endoscope unit 200 will be described with reference to FIGS. 1 and 2 .

The endoscope unit 200 includes an external module 210 and a camera module 220, and 6-axis movement (accelerometer, gyrometer) is possible inside the abdominal cavity with the abdominal skin interposed therebetween, and an LED (not shown) ), including lighting functions.

In addition, a fisheye lens 221b and a wide-angle lens 221a are provided so that a desired image can be selected and used according to the needs of the operator.

Here, it is possible to automatically search the location of the lesion S to be operated by providing a wireless location search device 222 (not shown).

For example, the wireless location search device 222 is capable of wireless power charging, various medical devices (blood sugar, heart rate, body temperature) or a part of a building/structure or automobile, an electronic board, an electronic sign receiving device ( electronic signature receiving device), a projector, or various measuring devices (eg, water, electricity, gas, or radio wave measuring devices, etc.). In various embodiments, the electronic device, such as the wireless positioning device 222, may be flexible, or a combination of two or more of the various devices described above, but is not limited thereto. In this document, the term user (operator) refers to a person using an electronic device or a device (eg, an artificial intelligence electronic device) using an electronic device capable of receiving wireless power or a wireless location search device 222 or may include

When describing the shape of the endoscope unit 200 in detail, the endoscope unit 200 has a dome-shaped external module 210 and a 'TT' shape with a convex top at the top, and a camera module that can be detached from the external module 210 by magnetic force. It includes 220, and the external module 210 and the camera module 220 are capable of mutual wireless communication and wireless charging.

First, when explaining the external module 210, the external module 210 is located on the surface of the epidermis of the skin. Due to the dome-shaped round shape, it can be positioned on the skin in a balanced way and can prevent damage to the skin surface.

Also, the external module 210 includes a control unit, and the control unit includes a memory unit 212 , a processor unit 211 , and a communication module 213 . A detailed description will be given later.

Next, the camera module 220 will be described. The camera module 220 penetrates the subcutaneous tissue of the human body and is inserted into the abdominal cavity of the human body.

Here, the external module 210 and the camera module 220 are magnetically positioned on the surface of the skin and inside the abdominal cavity, respectively, and may be positioned with the skin interposed therebetween by mutual magnetic force.

For this reason, since the existing endoscope having a constant length is not inserted into the abdominal cavity, it is possible to protect tissues or organs, and there is an advantage in that the inside of the abdominal cavity can be checked with a minimum incision.

In addition, the external module 210 and the camera module 220 may send and receive data through wireless communication.

Here, wireless communication means Bluetooth communication unit, BLE (Bluetooth Low Energy) communication unit, near field communication unit, WLAN (Wi-Fi) communication unit, Zigbee communication unit, infrared (IrDA, infrared Data Association) communication unit, WFD (Wi-Fi) communication unit. -Fi Direct) communication unit, UWB (ultra wideband) communication unit, and may include an Ant+ communication unit, but is not limited thereto.

Although it is exaggerated in the drawings, the camera module 220 inserted into the abdominal cavity must be able to pass through a trocar (Trocar, within 20 mm) perforated in the abdomen.

The camera module 220 includes an LED, a lens unit 221 and a wireless location search device 222 , and a communication chip for communicating with the external module 210 is provided.

First, when explaining the LED (not shown), the LED is a light irradiator capable of irradiating light to the lesion (S).

Light is irradiated to the lesion (S) to make it easier to find the lesion (S) in the abdominal cavity, and light is essential to check the inside of the closed abdominal cavity.

Here, the irradiated light is reflected and is incident on the lens unit 221 to be described later.

When describing the lens unit 221 , the lens unit 221 is provided at one end of the camera module 220 , refracts the image of the lesion S, and transmits it to the display unit 300 to be described later.

The lens unit 221 may include a wide-angle lens 221a and a fisheye lens 221b.

The wide-angle lens 221a may be configured as a lens whose focal length is adjusted. When the operator enlarges a specific part of the lesion S or wants to examine a region around the lesion S, the information can be obtained by adjusting the focus of the wide-angle lens 221a. In order to adjust the focal length of the wide-angle lens 221a, it is linked with the control unit of the external module 210 described above.

However, the wide-angle lens has the advantage of magnifying the lesion (S), but has a disadvantage that the entire lesion (S) cannot be seen because the wide angle does not exceed 180 degrees.

To this end, the lens unit 221 is further provided with a fisheye lens 221b, so that the lens can be selected by selecting it according to the intention of the operator.

If the fisheye lens 221b is described in more detail, the fisheye lens 221b is a lens having an angle of more than 180 degrees. The fisheye lens 221b has an image of an object with a constant brightness on the illuminating screen.

The structure of the fisheye lens 221b refracts all images, ie, a wide angle of 180 degrees, into a cone shape of 90 degrees by a concave lens, and is focused by an imaging lens.

An example of using the lens unit 221 will be described with reference to FIG. 5 . First, refer to FIG. 5(a).

In FIG. 5A , the entire screen can be viewed from the display unit 300 through the fisheye lens 221b to view the entire lesion S to be operated on. When the screen of the display unit 300 is divided into two screens, an image of the surgical site is formed with the fisheye lens 221b and the wide-angle lens 221a, respectively.

Here, the display unit 300 refers to a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), and a flexible display. (a flexible display), a three-dimensional display (3D display), and may include at least one of an e-ink display (e-ink display).

The operator finds the surgical lesion (S) while looking at the entire area of the lesion (S) to be operated with the fisheye lens (221b), and when the lesion to be operated (S) is found, the operator switches to a wide-angle lens as shown in FIG. The surgical lesion (S) will be enlarged.

Due to this, the operator can easily find the surgical lesion (S) in the abdominal cavity, and can view the surgical site in a full range, thereby increasing the efficiency of the operation.

A description of the wireless location search apparatus 222 will be provided later.

Next, in order to organize the configuration of the overall control according to the present invention will be described with reference to FIG.

First, when power is applied, the external module 210 , the camera module 220 , and the display unit 300 interact with each other. This interworking is provided to the user by processing the input signal or output signal, data sensing and image value of the components by the processor unit 211 of the control unit, or driving an application program stored in the memory unit 212 based on the above-mentioned signals. Video information can be provided.

Here, the control unit consists of MCU, CPU, ASIC (application specific integrated circuits), DSP (digital signal processors), DSPD (digital signal processing devices), PLD (programmable logic devices), FPGA (field programmable gate arrays) to drive the entire system. , micro-controllers, microprocessors, and other units for performing system operation.

In addition, the memory unit 212 is based on a hardware configuration, and may store data or commands to operate the external module 210 and the display unit 300 of the present invention based on an application program, an application, and a data value.

The type of the memory unit 212 may be various storage types such as RAM, ROM, EPROM, flash memory, and hard memory, and the memory unit 212 is a cloud capable of performing the storage function of the memory unit 212 on the Internet. and web storage.

In addition, the processor unit 211 may interwork with the display unit 300 through the communication module unit 213 of the control unit.

In short, the user can examine the lesion S by selecting the fisheye lens 221b or the wide-angle lens 221a, and the image of the lesion S is transmitted as an image to the display unit 300 .

Based on the image sent to the display unit 300, the operator performs surgery inside the abdominal cavity, and in order to move according to the operator's intention, that is, the lens unit 221 according to the position of the operator's forceps 100. In order to locate, the camera module 220 is provided with a wireless location search device 222 .

The wireless location search apparatus 222 may measure direction information of the camera module 220 . Here, including a gyro sensor unit (not shown), an acceleration sensor for measuring acceleration and a direction of geomagnetism may be measured. The measured value of the gyro sensor unit may be provided to an inertial measurement unit (IMU). The inertial measurement device may be provided in the form of one integrated unit consisting of a total of three sensors: an accelerometer capable of measuring movement inertia, a gyrometer capable of measuring rotational inertia, and a magnetic field capable of measuring an azimuth. It is possible to obtain information on 6 axes, that is, pitch, roll, yaw, and acceleration by using the measured values for the gyroscope and magnetic field.

Here, in conjunction with the lens unit 221 , the movement of the clamp unit 100 is output as an image with information captured by the camera module 220 .

In other words, the direction of the camera module 220 can be determined by the gyro sensor unit, and in conjunction with the lens unit 221, the movement of the clamp unit 100, that is, the camera module 220 in the direction desired by the operator is positioned to display an image. It can output to the display unit 300 .

Wireless positioning device 222 may also refer to transmitting an electric field, electromagnetic field, or any other energy from a transmitter to a receiver without the use of physical electrical conductors. For example, power may be transmitted through free space, or received or coupled by a power (electricity) reception moment to achieve power transmission for power output to a wireless field.

In addition, the wireless location search device 222 searches for a location, moves to the searched location, and transmits power, thereby transmitting an image, and inconvenience that a person of an image acquisition device called a conventional camera or lens must move has the advantage of being improved.

In addition, the wireless location search apparatus 222 can control the lens unit to be moved in a direction desired by the user, and after determining the location of the lesion S, actively search to determine the area where the image can be transmitted and can determine the optimal location within the area.

In addition, charging power may be supplied to a built-in battery to receive wireless power, and various power supply devices may be built-in according to the type and charging method of the battery.

Referring to FIGS. 3 and 4 in the above process, when an image is output to the display unit 300 through the lens unit 221 of the camera module 220, the foreign material (T) on the lens unit 221 as shown in FIG. ) or surgery may be possible without spattering of blood or tissue that occurs during surgery, but referring to FIG. 4 , tissue, blood, and foreign substances (T) generated at the surgical site are buried in the lens unit 221, resulting in noise or malfunction. It can interfere with surgery.

In addition, an image in which a foreign material (T) is attached to the image output to the display unit 300 is output, which may interfere with the operation of the operator.

Accordingly, a coating layer is formed to prevent contamination of blood, tissue, and foreign substances T that may be adhered to the lens unit 221 .

The coating layer (not shown) is to be coated using a coating composition, and the coating layer using the coating composition may exhibit a water repellent effect. Specifically, due to the water-repellent effect of the coating layer, it is possible to prevent the view from being obstructed by blood generated during surgery on the lens surface. In addition, the coating composition of the present invention exhibits a viscosity in a certain range, so that it is possible to form a uniform coating layer on the lens surface.

More specifically, the coating composition of the present invention may include a siloxane-based compound represented by the following Chemical Formula 1; organic solvents, inorganic particles and dispersants:

[Formula 1]

Here, n is an integer from 1 to 100.

After forming the coating layer using the coating composition of the present invention, the contact angle measurement result was confirmed to be 130 to 140 degrees, as can be seen in the range of the contact angle, it will be said that the excellent water repellency effect appears by the coating layer.

The inorganic particles may be selected from the group consisting of silica, alumina, and mixtures thereof. The average diameter of the inorganic particles is 70 to 100 μm, but is not limited to the above example. After the inorganic particles are formed as a coating layer on the lens surface, physical strength can be improved, and the viscosity can be maintained within a certain range to increase moldability.

The organic solvent is selected from the group consisting of methyl ethyl ketone (MEK), toluene, and mixtures thereof, and preferably methyl ethyl ketone may be used, but is not limited thereto.

As the dispersant, a polyester-based dispersant may be used, and specifically, as a polyester-based dispersion stabilizer composed of a copolymer of 2-methoxypropyl acetate and 1-methoxy-2-propyl acetate, TEGO-Disperse 670 (manufacturer : EVONIK), but is not limited to the above examples and any dispersant obvious to those skilled in the art can be used without limitation.

The coating composition may further include a stabilizer as other additives, and the stabilizer may include a UV absorber, an antioxidant, and the like, but is not limited to the above examples and may be used without limitation.

For forming the coating layer, the coating composition may include a siloxane-based compound represented by Formula 1 more specifically; organic solvents, inorganic particles and dispersants.

The coating composition may include 40 to 60 parts by weight of the siloxane-based compound represented by Formula 1, 20 to 40 parts by weight of inorganic particles, and 5 to 15 parts by weight of a dispersant based on 100 parts by weight of the organic solvent. In the case of the above range, a synergistic effect is expressed to the extent that the water repellency effect due to the interaction of each component has a critical significance, and when it is out of the above range, the synergistic effect is rapidly reduced or almost absent.

More preferably, the viscosity of the coating composition is 1500 to 1800 cP, and when the viscosity is less than 1500 cP, when it is applied to the lens surface, there is a problem that it is not easy to form a coating layer by flowing down, and when it exceeds 1800 cP, a uniform coating layer There is a problem that the formation of is not easy.

[Preparation Example 1: Preparation of coating layer]

1. Preparation of coating composition

A coating composition was prepared by mixing methyl ethyl ketone with the siloxane-based compound represented by the following formula (1), inorganic particles and a dispersing agent:

[Formula 1]

Here, n is an integer from 1 to 100.

A more specific composition of the antistatic composition is shown in Table 1 below.

	TX1	TX2	TX3	TX4	TX5
organic solvent	100	100	100	100	100
polysiloxane	30	40	50	60	70
inorganic particles	10	20	30	40	50
dispersant	One	5	10	15	20

(unit weight parts)

2. Preparation of coating layer

After coating the coating composition of DX1 to DX5 on one surface of the lens, it was cured to form a coating layer.

Experimental example

1. Evaluation of surface appearance

Due to the difference in viscosity of the coating composition, after the coating layer was prepared, sensory evaluation was performed on whether a uniform surface was formed. Whether or not a uniform coating layer was formed was evaluated, and evaluation was performed according to the following criteria.

O: uniform coating layer formation

X: Formation of non-uniform coating layer

	TX1	TX2	TX3	TX4	TX5
sensory evaluation	X	O	O	O	X

When the coating layer is formed, if the viscosity is less than a certain level, a flow occurs on the surface of the lens, so that it is difficult to form a uniform coating layer after the curing process. Accordingly, there may be a problem in that the production yield is lowered. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition to form a uniform coating layer.

2. Measurement of water repellency angle

After forming the coating layer on the lens surface, the results of measuring the water repellency angle are shown in Table 3 below.

	Forward contact angle (°)	Resting contact angle (°)	Retracting contact angle (°)
TX1	117.1±2.9	112.1±4.1	< 10
TX2	132.4±1.5	131.5±2.7	141.7±3.4
TX3	138.9±3.0	138.9±2.7	139.8±3.7
TX4	136.9±2.0	135.6±2.6	140.4±3.4
TX5	116.9±0.7	115.4±3.0	< 10

As shown in Table 3, after the coating layer was formed using the coating composition of TX1 to TX5, the result of measuring the contact angle was confirmed.

For TX1 and TX5, the receding contact angle was measured to be less than 10 degrees. That is, when it is out of the optimal range for preparing the coating composition, it was confirmed that the phenomenon of pinning water droplets occurs. On the other hand, it was confirmed that the peening phenomenon did not occur in TX2 to 4, thereby showing an excellent waterproof effect.
