Minimally invasive surgery is widely applied in the field of surgical treatment. Minimally invasive surgery has been applied in various surgical methods due to the advantage of fast recovery after surgery while reducing the size of the wound. To do this, however, you must first identify the lesion that you want to remove. Although cross-sectional images give a lot of information, they are not intuitive, so in reality, the position of the lesion is inevitably felt.

Surgical experience of a surgeon who had insisted on minimally invasive surgery and had difficulty finding a lesion even after a cross-sectional examination was published in several literatures.

Conventional wire localization and char have been used to indicate lesion location. Wire stereotactic surgery has a problem in that the entrance through the body and the lesion are far apart and wide peeling occurs. When charcoal is used, problems such as granuloma formation, foreign body reaction, and pigmentation may occur in the human body.

This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shape of the elements in the drawings and the like may be exaggerated to emphasize a more clear description. It should be noted that the same members in each drawing are sometimes shown with the same reference numerals. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention are omitted.

1 is a perspective view showing the configuration of the lesion position display apparatus 100 according to the present invention, Figure 2 is a cross-sectional view showing a cross-sectional configuration of the lesion position display apparatus 100 is coupled.

As shown, the lesion position display apparatus 100 according to the present invention includes a stereotactic head 110 formed of a material having magnetic force, a suture 120 integrally formed on the stereotactic head 110, and the suture 120. Removably coupled to the stereotactic head 110 to accommodate therein includes a head pressure tube 130 for pressing the stereotactic head 110 to reach the surgical lesion inside the human body.

Here, the stereotactic head 110 is formed of a material having a magnetic force, such as a magnet, when the stereotactic head 110 is inserted into the lesion inside the human body, as shown in Figure 6, the operator using the external magnet 300 Intuitively find the position of the stereotactic head 110 through the skin from the outside of the position and the incision is only a minimum length to the stereotactic head 110. Thereby, it is possible to perform minimally invasive surgery, and there is an advantage that can solve the problems caused when using conventional wire positioning and charcoal.

The stereotactic head 110 is positioned on the surgical lesion to generate a magnetic force so that the surgical step can find the surgical lesion outside the human body to display the location of the lesion. The stereotactic head 110 is preferably formed of a material and size having a minimum magnetic field that can be found through a magnet outside the human body. For this purpose, the stereotactic head 110 is formed of a magnet having a magnetic field in the range of 0.1 to 0.3.

The stereotactic head 110 is formed to have a smaller diameter (d1> d2) from the rear end to the front end so as to easily penetrate the lesion. For this purpose, the stereotactic head 110 is formed in a conical shape having a triangular or trapezoidal cross-sectional shape.

On the outer circumferential surface of the stereotactic head 110, a thread 111 is formed spirally along the longitudinal direction. The thread 111 serves to prevent the positional deviation of the stereotactic head 110 and at the same time to easily dig the inside of the lesion (C) when the pressure is rotated by the head pressure tube 130.

The stereotactic head 110 is preferably formed to have a diameter of less than 1mm to easily penetrate the lesion (C).

On the other hand, the rear end of the stereotactic head 110 is formed so that the coupling groove 113 to which the head pressure pipe 130 is coupled.

Suture 120 is coupled to the rear end of the stereotactic head 110 is formed to extend a predetermined length. Suture 120 is formed of a material having absorbency. Suture 120 has a plurality of scales 125 formed to protrude radially outward along the longitudinal direction, as shown in FIG. Scales 125 direct the operator's field of view toward stereotactic head 110.

 The scale 125 is formed to protrude in a direction opposite to the direction in which the stereotactic head 110 is inserted. That is, it is formed in the form of a triangle formed vertices toward the stereotactic head 110. By the shape of the scales 125, the suture 120, when an external force is applied in the direction in which the stereotactic head 110 is separated, generates a resistance between the body tissues so as not to be easily separated.

Accordingly, even when an external force is applied to the suture 120 during surgery, the stereotactic head 110 may be prevented from being caught by the scale 125.

Suture 120 is, as shown in Figure 6 when the stereotactic head 110 is inserted into the lesion (C), one end 121 is fixedly coupled to the stereotactic head 110, the other end 123 is a human body Exposed to a certain length on the outside. By the structure of the suture 120, after pressing the suture 120 to the outside it can discharge the stereotactic head 110 to the outside of the human body. As a result, the stereotactic head 110 may be prevented from remaining or lost in the human body.

Head pressure tube 130 is detachably coupled to the rear end of the stereotactic head 110 to press the stereotactic head 110 can be inserted into the surgical lesion (C). The head pressurizing tube 130 is formed in the form of a hollow tube with an empty interior as shown in FIG. Suture 120 is accommodated in the empty interior.

The front end of the head pressure tube 130 is formed so that the coupling end 131 is blocked. The coupling end 131 has a suture through hole 132 through which the suture 120 is inserted, and a plurality of coupling protrusions 133 protrude from the suture through hole 132.

The head pressure tube 130 is formed in the shape of a tube having a predetermined length to allow the operator to hold by hand to rotate the stereotactic head 110 into the lesion (C). Coupling protrusion 133 is fitted into the coupling groove 113 so that the head pressure tube 130 may apply a force to the stereotactic head 110.

As shown in FIG. 2, the operator presses the rear end of the head pressure tube 130 while the coupling protrusion 133 is fitted into the coupling groove 113 to insert the stereotactic head 110 into the lesion.

Here, the inner diameter (r1) of the head pressure tube 130 is formed smaller than the outer diameter (d1) of the stereotactic head 110, the outer diameter (r2) is formed equal to or smaller than the outer diameter (d1) of the stereotactic head (110). .

A lesion position display process using the lesion position display apparatus 100 of the present invention having such a configuration will be described with reference to FIGS. 3 to 6.

First, as shown in (a) of FIG. 3, the operator inserts the catheter 200 into the surgical lesion C by using a special camera image such as tomography results and an endoscope. At this time, the catheter 200 is inserted into the penetrating 210 is coupled.

By the sharp end of the needle 210, the catheter 200 and the needle 210 are inserted into the lesion (C). And, as shown in (b) of Figure 3 discharges the piercing 210 to the outside.

At this time, the inner diameter of the catheter 200 is formed larger than the outer diameter (d1) of the stereotactic head 110 so that the stereotactic head 110 and the head pressure tube 130 is easily inserted into the catheter 200.

As shown in (a) of FIG. 4, the operator pushes the stereotactic head 110 into the catheter 200 with the head pressure tube 130 coupled to the rear end of the stereotactic head 110. The operator presses the head pressure tube 130 to press the stereotactic head 110 to the tip of the catheter 200.

As shown in (b) of FIG. 4, when the stereotactic head 110 enters the tip of the catheter 200, the head pressure tube 130 is rotated and the stereotactic head 110 is formed by the threads of the stereotactic head 110. ) To penetrate the human tissue (B) to enter the lesion (C).

When the stereotactic head 110 is positioned in the lesion (C), the catheter 200 is discharged to the outside as shown in (c) of FIG.

Then, as shown in (a) of FIG. 5, the head pressure pipe 130 is separated to the outside. The operator applies an external force to separate the coupling protrusion 133 from the coupling groove 113 and separate the head pressurizing tube 130 to the outside. At this time, the other end 123 of the suture 120 is in a state exposed to the outside of the human body.

As illustrated in FIGS. 5B and 6, the operator searches for a lesion location using an external magnet 300 from outside the human body.

Stereotactic head 110 located in the lesion (C) generates a magnetic force. The external magnet 300 located outside the human body is in close contact with the skin where the lesion (C) is located by the attraction. The operator intuitively recognizes the skin area at the position perpendicular to the lesion (C).

In addition, the operator may perform minimally invasive surgery by minimizing the skin (A) where the lesion (C) is located.

The location of the lesion can be used for the location of the lateral cervical lymph node in the head and neck, the location of the tumor in primary parathyroid hyperplasia, and the location of recurrence. In addition, it can be used in place of the positioning using wire in the breast lesions that are not touched. In addition, during minimally invasive surgery for the gastrointestinal tract, the stereotactic head 110 is inserted into the intestinal membrane with the lesion in advance, and the location of the lesion may be visually confirmed by an external magnet in the abdominal cavity.

As described above, in the lesion position display apparatus and the lesion position display method using the same, a stereotactic head having magnetic force is inserted into the lesion using a catheter, and the position of the lesion can be accurately found using an external magnet from the outside of the human body. .

Such a lesion position display process of the present invention has the advantage that the procedure is easy, harmless to the human body and less intuitive complications possible. This can be applied to various minimally invasive surgery.
