Description

Suture Training System {Suture Training System}

The present invention relates to a suture training system, and more particularly, to a suture training system for training medical personnel.

In general, in the medical field, suture is the most basic and most used surgical technique. However, despite the same degree of trauma, as can be seen from the fact that the prognosis of wounds varies according to the skill level of medical personnel, it requires a lot of training for medical personnel to provide sutures above a certain level to patients.

However, most of the trainees improve their skills through the process of recognizing the senses by simply repeating them using artificial skin or animal carcasses.

Accordingly, the training method has a problem in that experts have to visually evaluate and provide feedback for the evaluation of the training results. That is, it takes a lot of time for training, and there are disadvantages in that it can be based on a subjective evaluation, such as the evaluation method varies according to individual preferences.

In order to supplement this, a simulator that provides an indirect experience using virtual reality as shown in the following patent document and at the same time can check feedback according to a predetermined evaluation method has been proposed.

However, the experience provided by the simulator using virtual reality is only an indirect experience, and it is far from the clinical experience made by the actual skin tissue. As a result, there is a problem in that the most important sensory training is excluded from skill training.

In order to overcome these problems, it is necessary to develop a suture training system that can immediately provide objective feedback while enabling sensory training close to actual clinical experience.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art may easily implement the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and the same reference numerals are assigned to the same or similar components throughout the specification.

Hereinafter, a suture training system according to an embodiment of the present invention will be described in more detail with reference to the drawings.

Referring to FIG. 1 , the suture training system 100 according to an embodiment of the present invention includes a power supply unit 110 , a suture position detection sensor 120 , and a control unit 130 .

The suture training system 100 is a simulation system for training the suture process as shown in FIG. 2 . Here, the suturing procedure may refer to a medical practice used to sew and maintain torn or incised body tissue after injury or surgery.

In this case, the suturing training system 100 describes suturing for skin tissue exposed to the outside as an example, but is not limited thereto, and may also be applied to suturing of internal organs.

2 and 3, the suturing training system 100 uses the suture position detection sensor 120 built in the human body model 10 that reproduces the human body, the suturing means 160, for example, by using a needle. The suture position can be detected and visualized.

The power supply unit 110 supplies power to the suture position detection sensor 120 . Here, the power supply 110 may be a DC voltage source.

At this time, the suture position detection sensor 120 detects the position with respect to the x-axis and y-axis directions, as will be described later. For this purpose, the power supply unit 110 alternately supplies power with respect to the x-axis and y-axis directions. have.

As described above, the suture position detection sensor 120 is embedded in the manikin 10 for suture training. Referring to FIG. 3 , the suture position detection sensor 120 is disposed under the artificial skin 11 of the human body model 10 . That is, the suture position detection sensor 120 may be embedded in the human body model 10 and the upper surface may be covered by the artificial skin 11 .

At this time, the artificial skin 11 may be formed with an incision simulating a wound in part. That is, the artificial skin 11 may include a form in which the artificial skin 11 is torn on both sides in a partial area of the artificial skin 11 that is smooth without a break.

Here, when the suture means 160 made of a conductive material penetrates the artificial skin 11 adjacent to the incision site during suturing training, the suture position detection sensor 120 disposed below also penetrates. In this case, the sealing position detection sensor 120 may distribute a potential corresponding thereto based on the sealing position of the sealing means 160 by the voltage applied from the power supply unit 110 .

4, the sealing position detection sensor 120 according to the embodiment of the present invention uses the principle of a potential that linearly decreases according to the direction of current flow on the conductive material, the first driving layer 121, It includes a first insulating layer 122 , a second driving layer 123 , a second insulating layer 124 , and a sensing layer 125 .

Here, the first driving layer 121 , the first insulating layer 122 , the second driving layer 123 , the second insulating layer 124 , and the sensing layer 125 are sequentially stacked in one direction. For example, based on the sensing layer 125, it may be sequentially stacked on the upper side.

In this case, the suture position detection sensor 120 is inexpensive and may be formed in the form of a thin film. That is, the sealing position detection sensor 120 may be formed of a tape or a thin film. However, the suture position detection sensor 120 is not limited thereto.

For example, the first driving layer 121 , the second driving layer 123 , and the sensing layer 125 may be formed of a plate-shaped conductive tape or an insulating thin film, but is not limited thereto. In addition, the first insulating layer 122 and the second insulating layer 124 may be formed of a plate-shaped insulating tape or an insulating thin film, but is not limited thereto.

More specifically, the first driving layer 121 , the second driving layer 123 and the sensing layer 125 are formed by evenly applying a conductive ink to a cloth tape and adhering a copper tape (electrode) to both ends before the ink hardens. can be formed. In addition, the first insulating layer 122 and the second insulating layer 124 may be formed using a plastic tape or an Opsite film.

Accordingly, the suture position detection sensor 120 can be easily embedded under the artificial skin 11 of the human body model 10 .

Moreover, since the suture position sensor 120 can be easily penetrated without generating additional resistance when the artificial skin 11 is sutured by the suturing means 160 , the reality of suturing can be improved.

Furthermore, the suture position detection sensor 120 can be manufactured at a low cost, so it is possible to reduce the economic burden even if it is sutured together with the artificial skin 11 and discarded after being used once.

The first driving layer 121 is made of a conductive material. Here, the first driving layer 121 may have a predetermined resistance value. Power may be applied to the first driving layer 121 from the power supply unit 110 .

In addition, the first driving layer 121 includes a first electrode 121a and a second electrode 121b formed on both sides. For example, in the first driving layer 121 , the first electrode 121a and the second electrode 121b may be formed on both sides of the y-axis direction (front and rear directions in FIG. 4 ).

Here, power may be applied to the first electrode 121a and the second electrode 121b from the power supply unit 110 . For example, the first electrode 121a may be connected to the positive terminal of the power supply unit 110 , and the second electrode 121b may be connected to the negative (ground) terminal of the power supply unit 110 .

In this case, the first electrode 121a and the second electrode 121b may be formed on both sides of the first driving layer 121 with a constant width, respectively.

The first insulating layer 122 is made of an insulating material. Also, the first insulating layer 122 may be disposed on one side of the first driving layer 121 . For example, the first insulating layer 122 may be bonded to the lower surface of the first driving layer 121 .

The second driving layer 123 is made of a conductive material. Here, the second driving layer 123 may have a predetermined resistance value. In this case, the second driving layer 123 may be disposed on one side of the first insulating layer 122 . For example, the second driving layer 123 may be bonded to the lower surface of the first insulating layer 122 . Power may be applied to the second driving layer 123 from the power supply 110 .

In addition, the second driving layer 123 includes a third electrode 123a and a fourth electrode 123b formed on both sides. Here, the third electrode 123a and the fourth electrode 123b are disposed to be perpendicular to the first electrode 121a and the second electrode 121b, respectively. For example, in the second driving layer 123 , a third electrode 123a and a fourth electrode 123b may be formed on both sides in the x-axis direction (left and right directions in FIG. 4 ).

Here, power may be applied to the third electrode 123a and the fourth electrode 123b from the power supply unit 110 . For example, the third electrode 123a may be connected to the positive terminal of the power supply unit 110 , and the fourth electrode 123b may be connected to the negative (ground) terminal of the power supply unit 110 .

In this case, the third electrode 123a and the fourth electrode 123b may be formed on both sides of the second driving layer 123 with a constant width, respectively.

The second insulating layer 124 is made of an insulating material. Also, the second insulating layer 124 may be disposed on one side of the second driving layer 123 . For example, the second insulating layer 124 may be bonded to the lower surface of the second driving layer 123 .

The sensing layer 125 is made of a conductive material. Here, the sensing layer 125 may have a predetermined resistance value. In this case, the sensing layer 125 may be disposed on one side of the second insulating layer 124 . For example, the sensing layer 125 may be bonded to the lower surface of the second insulating layer 124 . The sensing layer 125 may detect a voltage corresponding to the sealing position of the sealing means 160 .

In addition, the sensing layer 125 includes a fifth electrode 125a formed along the circumference. In this case, the fifth electrode 125a may be formed on all four sides of the sensing layer 125 with a constant width.

Here, the first driving layer 121 , the second driving layer 123 , and the sensing layer 125 may have the same size. In this case, the first driving layer 121 , the second driving layer 123 , and the sensing layer 125 may have a rectangular shape. For example, the first driving layer 121 , the second driving layer 123 , and the sensing layer 125 may have a square shape.

Accordingly, the suture position detection sensor 120 can accurately and precisely detect and calculate the suture position (or path) in two-dimensional coordinates, thus ensuring the reliability of the training result.

On the other hand, the sealing position detection sensor 120 according to the embodiment of the present invention may further include protective layers (126, 127). Here, the protective layers 126 and 127 may be made of the same insulating material as the first insulating layer 122 and the second insulating layer 124 .

The first protective layer 126 may be disposed on the other side of the first driving layer 121 . That is, the first protective layer 126 may be disposed on the upper surface of the sealing position detection sensor 120 to insulate and protect the first driving layer 121 from the outside.

The second protective layer 127 may be disposed on one side of the sensing layer 125 . That is, the second protective layer 127 may be disposed on the lower surface of the sealing position detection sensor 120 to insulate and protect the detection layer 125 from the outside.

Hereinafter, the operation principle of the suture position by the suture position detection sensor 120 will be described in more detail with reference to FIGS. 5 to 7 .

Referring to FIG. 6 , power is applied from the power supply unit 110 to the driving layer for the calculation of the one-dimensional coordinates of the suture position. Here, although the second driving layer 123 for the x-axis direction is described based on the description, the same can be applied to the first driving layer 121 for the y-axis direction.

At this time, the third electrode 123a of the second driving layer 123 is connected to the positive terminal of the power supply 110 through the positive wiring 111 , and the fourth electrode 123b is connected to the negative wiring 112 through the negative wiring 112 . It is connected to the negative (ground) terminal of the power supply unit 110 . Here, the potential of the third electrode 123a is equal to the applied voltage V _S of the power supply unit 110 , and the potential of the fourth electrode 123b is equal to 0V.

At this time, when the sealing means 160 penetrates a specific position of the second driving layer 123 , the second driving layer 123 is between _{the penetrating point P 1 of the sealing means 160 and the fourth electrode 123b.} The first resistor R ₁ is formed according to the resistance value of and the distance L _{1 therebetween.} Similarly, a second resistance R ₂ is formed between the sealing point P ₁ and the fourth electrode 123b according to the resistance value of the second driving layer 123 and the distance L _{2 therebetween.} .

In this way, the second driving layer 123 can be represented by _{constant resistance values R 1} , R ₂ according to the distance between the third electrode 123a and the fourth electrode 123b as shown in Equation 1 below. have.

[Equation 1]

Here, ρ is the resistivity of the second driving layer 123 , L ₁ is the distance between the fourth electrode 123b and the sealing point P _{1 , A 1} is the fourth electrode 123b and the sealing point P ₁ ) A vertical cross-sectional area between them, L ₂ is a distance between the third electrode 123a and the sealing point P ₁ , and A ₂ is a vertical cross-sectional area between the third electrode 123a and the sealing point P _{1 .} However, in an embodiment of the present invention, A ₁ and A ₂ may be the same. As such, when A ₁ and A ₂ are equal to each other, the resistances R ₁ and R ₂ will be proportional to the lengths L _{1 and} L _{2 .}

Therefore, the potential (V _p ) of the sealing point (P ₁ ) can be expressed as a voltage division with respect to the applied voltage (V _{S ) as in Equation 1 below.}

[Equation 2]

Here, as shown in the potential graph for each position of FIG. 5 , the potential at the sealing point _{P 1 is determined by the resistance value of the second driving layer 123 at the sealing point P 1} and the fourth electrode 123b. ), it can be seen that it increases linearly with the distance (L _{1 ) between them.}

By substituting Equation 1 into Equation 2 to _{organize L 1} , it is as Equation 3 below.

[Equation 3]

Here, L is the distance between the third electrode 123a and the fourth electrode 123b, and is L ₁ +L ₂ .

In this way, _{when the potential at the sealing point P 1} is detected, the distance L ₁ from the fourth electrode 123b can be calculated, and thus the sealing position of the sealing means 160 can be calculated.

That is, the position calculating unit 132 is a power supply unit 110 for the potential Vp detected _{at the sealing point P 1} based on the distance L between the third electrode 123a and the fourth electrode 123b. The sealing position can be calculated by the ratio of the voltage (V _{S ) applied in the .}

Meanwhile, a potential at the sealing point P ₁ may be detected through the sensing layer 125 . Here, when the suture means 160 made of a conductive material penetrates the artificial skin 11 , the suture position detection sensor 120 also passes through the artificial skin 11 .

At this time, as the sealing means 160 passes through the sealing position detection sensor 120 , the second driving layer 123 and the detection layer 125 are electrically connected through the sealing means 160 .

Referring to Figure 6, according to the second drive layer 123 and sense layer 125, an output terminal a third resistor (R ₃₎ and the sense layer 125 by, the sealing means 160 between the (S _O) of A fourth resistor (R ₄ ) is additionally formed.

That is, the second between the sealing point (P ₂₎ of the closure point (P ₁₎ and the sensing layer 125 of the driving layer 123, a third resistor (R ₃₎ by a resistance value having a sealing means 160, is formed _{In addition, a fourth resistor R 4} is formed _{between the sealing point P 2} of the sensing layer 125 and the fifth electrode 125a by the resistance value of the sensing layer 125 .

At this time, the sensing layer 125 can be provided with a pull-down resistor (R _p) to the output terminal (S _O). Here, the resistance value of the pull-down resistor R _p may be 100 times or more greater than the sum of the resistance value of the sensing layer 125 and the resistance value of the sealing means 160 . As a result, the detected voltage at the output terminal (S _O) can be prevented from being randomly floating.

Referring to FIG. 7 , _{between the sealing point (P 1} ) and the ground, the first resistor (R ₁ ) is the series resistance of the third resistor (R ₃ ), the fourth resistor (R ₄ ), and the pull-down resistor (R _p ) and connected in parallel

Here, since the resistance value of the pull-down resistor R _p is much greater than the sum _{of the resistance value R 3 by the sealing means 160 and the resistance value R 4} by the sensing layer 125 , most voltages are pulled down It is applied to the resistance (R _p ).

In addition, most of the current I flowing through _{the second resistor R 2} of the second driving layer 123 flows into _{the first resistor R 1 .} That is, the current I _{1 flowing through the first resistor R 1} of the second driving layer 123 flows through the third resistor R ₃ , the fourth resistor R ₄ , and the pull-down resistor R _p . It is much greater than the current I _{2 .}

Thus, by measuring the voltage across the pull-down resistor (R _p) provided to the output terminal (S _O) of the sense layer 125, it is possible to calculate the potential of the closure point (P _1).

On the other hand, in order to determine the position in two-dimensional coordinates using the first driving layer 121 and the second driving layer 123 of the suture position detection sensor 120, the first driving layer 121 and the second driving layer Power is alternately applied to (123).

Referring to FIG. 8 , the suture training system 100 includes a switch unit SW that switches to alternately supply the output power of the power supply unit 110 to the first driving layer 121 and the second driving layer 123 . may include more.

That is, since one sensing layer 125 is used for the first driving layer 121 for detecting the y-axis direction and the second driving layer 123 for detecting the x-axis direction, the switch unit SW alternately applies power to the first driving layer 121 and the second driving layer 123 . Accordingly, the first driving layer 121 and the second driving layer 123 may be selectively activated.

In this case, the position calculating unit 132 may detect a potential with respect to any one of the first driving layer 121 and the second driving layer 123 according to the alternating power of the power supply unit 110 . That is, the position calculating unit 132 may detect the potential _{of the suture point P 1} with respect to one of the x-axis direction and the y-axis direction. Therefore, the position calculating unit 132 may calculate the x and y coordinates of the position of the suture point P1 by the alternating application of power.

For example, the switch unit SW may include a transistor.

Referring to FIG. 9 , the first transistor S _1a and the second transistor S _1b may be respectively connected to the first electrode 121a and the second electrode 121b of the first driving layer 121 . In addition, the third transistor S _2a and the fourth transistor S _2b may be respectively connected to the third electrode 123a and the fourth electrode 123b of the second driving layer 123 .

In this case, the first transistor S _1a and the second transistor S _1b connected to the first driving layer 121 may be simultaneously controlled by the first signal S _{1 . Similarly, the third transistor S 2a} and the fourth transistor S _2b connected to the second driving layer 123 may be simultaneously controlled by the second signal S _{2 .}

Here, the second signal S ₂ may be an inverted signal of the first signal S _{1 .} In addition, the first signal S ₁ and the second signal S ₂ may have a constant pulse width. As a result, the first transistor (S _1a ) to the fourth transistor (S _2b ) are switched at regular time intervals, and the first transistor (S _1a ) and the second transistor (S _1b ) and the third transistor (S _2a ) and The fourth transistor S _2b may be turned on at different times. For example, the first signal (S ₁ ) and the second signal (S ₂ ) may be a square wave having a frequency of 200 Hz. In this case, the position calculating unit 132 may detect the suture position at a frequency of 100 Hz.

That is, when the first transistor S _1a and the second transistor S _1b are turned on, and the third transistor S _2a and the fourth transistor S _2b are turned off, the power supply unit 110 first drives A voltage V _S may be applied to the layer 121 .

Similarly, when the third transistor (S _2a ) and the fourth transistor (S _2b ) are turned on, and the first transistor (S _1a ) and the second transistor (S _1b ) are turned off, the power supply unit 110 is the second A voltage V _S may be applied to the driving layer 123 .

Accordingly, it is possible to accurately calculate the suture position in two-dimensional coordinates while using one sensing layer.

Referring back to FIGS. 1 and 2 , the controller 130 of the suture training system 100 according to an embodiment of the present invention calculates the suture position when the suturing means 160 penetrates the artificial skin 11 . Thus, the suture path can be calculated.

In this case, the control unit 130 may control the power supply unit 110 to supply power alternately with respect to the direction of the suture position detection sensor 120 . Here, the control unit 130 may include a position calculating unit 132 and a suture path calculating unit 134 .

The position calculating unit 132 detects a potential corresponding to the position of the suturing means 160 from the suture position detection sensor 120 . At this time, the position calculating unit 132 may calculate the position of the sealing means 160 according to the ratio of the voltage applied to the sealing position detection sensor 120 from the power supply unit 110 to the detected potential. The calculation of the position of the suturing means 160 will be described later with reference to FIG. 5 .

The suturing path calculating unit 134 may calculate a suturing path by the suturing unit 160 by connecting at least two or more positions calculated by the position calculating unit 132 with each other. For example, the needle-like suturing means 160 is sutured by connecting the position of the point where it penetrates while coming out from the lower surface of the artificial skin 11 in the upper surface direction, and the point at which it penetrates as it enters from the upper surface of the artificial skin 11 to the lower surface. path can be calculated.

In this case, the suture training system 100 may further include a storage unit 140 . That is, the suturing path calculating unit 134 may store the detected position with respect to the suturing unit 160 in the storage unit 140 . In addition, the suturing path calculating unit 134 may calculate a suturing path from the stored suture positions.

Also, referring to FIG. 2 , the suture path calculating unit 134 may control to display the calculated suture path on the image corresponding to the human body model 10 through the display unit 150 to be described later.

That is, as shown in FIG. 3 , the suturing path calculating unit 134 may graphically provide the suturing path together with the reference path so that the trainee can recognize the degree of error occurring during suturing.

In an embodiment of the present invention, the control unit 130 may further include a suture training evaluation unit 136 .

In more detail, the controller 130 may quantify the suture quality by the trainee by comparing the suture path by the trainee with the reference path and calculating the degree of error.

For example, the degree of difference may be quantified by measuring the angle at which the reference path is inclined with respect to the X and Y axes and the angle at which the suture path by the trainee is inclined with respect to the X and Y axes. As another example, the degree of parallelism of each suture line or the uniformity of the suture length may be quantified according to the progress of the suture path.

In addition, the suture training evaluation unit 136 may analyze the training performance of the trainee for each period by comparing the suture paths by date stored in the storage unit 140 with each other. On the other hand, it is also possible to recognize the training achievements (suture route) for each trainee separately and compare them with each other. However, the application of the suture training evaluation unit 136 is not limited thereto, and various quantitative indicators capable of evaluating the suture quality may be adopted.

As described above, the training performance quantified through the suture training evaluation unit 136 is shown through the display unit 150, so that the trainee can objectively receive feedback on his/her own training performance.

The suture training system 100 according to an embodiment of the present invention may further include a display unit 150 for displaying a suturing path.

The display unit 150 superimposes the suture path calculated by the suturing path calculation unit 134 on the corresponding position of the human body model 10, or displays the above-described training evaluation result, information necessary in the training process. is displayed in the form of an image or text. Therefore, the trainee can autonomously improve the educational effect.

As shown in FIG. 2 , the trainee can immediately check the training-related feedback by placing the display unit 150 in the vicinity of the suture while training the suture through the manikin 10 including the suture position detection sensor 120 . have.
