Description

Customized surgical guide, customized surgical guide manufacturing method and creation program {CUSTOMIZED SURGERY GUIDE APPARATUS, MANUFACTURING METHOD AND CREATING PROGRAM FOR CUSTOMIZED SURGERY GUIDE}

The present invention relates to a customized surgical guide, and a method and generation program for creating a customized surgical guide. More specifically, it relates to a customized surgical guide that enables surgery that matches the condition of the patient's treatment target area during surgery on a specific patient, and to creating the same. It is about methods and programs.

During surgery, medical staff determines the area where surgery will be performed based on medical images. It has the disadvantage of having to rely heavily on the surgeon's guess and experience, so there may be cases where the entire area that needs to be excised is not removed, and there are also cases where a large area is excised because the exact range of the area to be removed is not known. .

Additionally, a method of marking the removal area on the skin surface before starting the surgery is sometimes used. However, the marker displayed on the skin surface is difficult to match with the inside when surgery is started and the body part is excised, lowering the accuracy in determining the extent of surgery inside the body part. Currently, in order to mark a specific point inside the body, an ultrasound or mammography guide H-wire is inserted to remove the relevant part. However, this also has the disadvantage of being difficult to accurately mark, and the problem of pain for the patient and time-consuming procedure. there is. Sometimes, part of the H-wire is cut or lost during surgery and remains in the body.

The present invention is a customized surgery that three-dimensionally displays the removal area within the body part where surgery is to be performed, allowing the removal area (i.e., treatment target area) to be accurately visually confirmed even during incision and surgery on the body part. We aim to provide guides and customized surgical guide creation methods and creation programs.

According to the present invention as described above, it has various effects as follows.

First, the optimal surgery for the patient can be performed by using a customized surgical guide that assists the patient in performing the surgery. For example, when a surgical lesion (e.g., tumor) within the affected area needs to be removed, one or more staining pillars are created within the body part using a patient-customized surgical guide, which allows the removal area to be visually confirmed even during surgery. There is. Through this, medical staff can treat by removing minimal tissue through 2D or 3D marking using a dye pillar.

Second, the surgical guide can be aligned in the correct position based on the reference point of the body part, allowing the accurate surgical area to be displayed. Even if the sub-reference point is located on the outside of the surgical guide, the position can be aligned through the alignment guide unit, so a sufficiently accurate surgical area can be displayed even with a small-sized surgical guide.

Third, the operator's field of view can be secured by forming a body part cover only in necessary areas. In addition, manufacturing costs can be reduced, lowering unit costs and shortening manufacturing times.

Fourth, since the guide tube is created by calculating the depth to the target point based on medical image data, medical staff can perform surgery without worrying about the depth at which medical tools (for example, syringes) are inserted. In other words, if you insert the medical tool all the way into the guide tube of the custom-fit surgical guide, it will reach the target point, allowing you to easily perform the surgery.

Fifth, by manufacturing the body part cover to correspond to the body shape, the guide tube can be placed at a point where it can accurately reach the target point when inserting a medical tool. Through this, it is possible to prevent treatment from being performed on the wrong target point or incorrect marking within a body part.

Hereinafter, a customized surgical guide, a method for creating a customized surgical guide, and a program according to embodiments of the present invention will be described in detail.

Figure 1 is an exemplary diagram of a customized surgical guide 10 according to an embodiment of the present invention.

Referring to Figure 1, the customized surgical guide 10 according to an embodiment of the present invention includes a guide tube 100 and a body part cover 200.

The guide tube 100 is a tube into which medical tools can be inserted. The guide tube 100 has a larger diameter than the part of the medical tool inserted into the body. Since some medical tools are inserted into the body, it may be dangerous if foreign substances adhere to the wall of the guide tube 100. Therefore, a portion of the medical tool is formed to have a wide diameter so that it can be inserted without contacting the wall surface of the guide tube 100. For example, when the medical tool is a syringe equipped with an injection needle, the guide tube 100 is formed with a larger diameter than the injection needle and serves to support insertion at an accurate angle in accordance with the body of the syringe. The guide The tube 100 is formed to a length that limits the depth at which a medical tool can be inserted into the body to a set depth from the first point to the target point 40. For example, when the medical tool is a syringe equipped with an injection needle, the guide tube 100 is used to ensure that the needle enters only a certain depth into the body. After the needle is inserted into the guide tube 100, the syringe is inserted into the guide tube 100. It is formed to take (100). For example, if the length of the injection needle is A and the length of the guide tube 100 is B, as the syringe is caught in the guide tube 100, the needle will only enter the body as long as the length corresponding to 'A-B'. I go in. Therefore, the customized surgical guide 10 sets the depth at which the medical tool is inserted into the body by the guide tube 100.

The length of the guide tube 100 is set based on the distance from the first point on the body surface to the target point 40 that the medical tool must reach on the medical image data. In one embodiment, when the customized surgical guide 10 is injected by a 3D printer, the computer analyzes the CT image or MRI image to determine the distance from a specific first point on the surface of the body part to a specific target point 40. Calculate Thereafter, the length of the guide tube 100 is calculated by subtracting the calculated distance from the length of the medical tool used during surgery (for example, the length of the syringe needle). Through this, it is possible to set the length of the guide tube 100 of the customized surgical guide 10 that matches the patient's treatment target area 20.

The customized surgical guide 10 according to an embodiment of the present invention has a number of guide tubes 100 corresponding to the number of target points 40 in the body. Since each guide pipe 100 is created at a distance and direction to reach the target point 40 from the first point, the guide pipe 100 is provided in a number corresponding to the number of target points 40.

As shown in FIG. 1, the body part cover 200 is coupled with one or more guide tubes 100. That is, the body part cover 200 is provided with a hole through which the medical tool inserted through the guide tube 100 passes in the direction of the body part. Through this, the medical tool inserted through the guide tube 100 invades or is inserted into the body part along the extension line of the guide tube 100.

The body part cover 200 is a cover that covers the surface of a specific body part. Specifically, the body part cover 200 is formed to correspond to the surface of the patient's body part. In one embodiment, the body part cover 200 is created based on body surface data obtained based on medical image data. For example, when the body part cover 200 is injected with a 3D printer and the breast of a breast cancer patient is used as the body part, the surface of the patient's breast shape at the time of the MRI or CT image is based on the MRI image or CT image. Generate shape data of the body part cover 200 that matches. Through this, the body part cover 200 is made to fit the surface of the body part, and when a medical tool is inserted into the guide tube 100 of the customized surgical guide 10 created based on medical image data, the medical tool is inserted into the body. Make sure to accurately reach the target point (40) within the area. That is, the body part cover 200 is set so that the guide tube 100 is located at the first point set in the treatment planning process based on medical image data.

In addition, in another embodiment, the customized surgical guide 10 includes a reference point 300 for accurate positioning when applied to a patient, as shown in FIG. 2. The reference point 300 corresponds to a specific position of the body part to ensure that the customized surgical guide 10 is placed at the exact position set during surgical planning or modeling. For example, when the body part is a breast, the customized surgical guide 10 forms a hole of the same size as the nipple at a point corresponding to the nipple, and uses the nipple as a reference point 300 to form a hole on the surface of the body part. Set the correct attachment location.

In addition, in another embodiment, the customized surgical guide 10 is, when the body part including the treatment target area 20 is a part whose shape changes depending on the posture, the body part cover 200 is, It covers body parts and plays the role of fixing them in a specific shape. For example, in the case of breasts, the shape may change depending on the patient's posture. Therefore, the medical tool can accurately reach the target point 40 through the customized surgical guide 10 only when the breast has the same shape as when setting the target point 40 based on medical image data. Therefore, by manufacturing the body part cover 200 in a form that covers the entire body part, the body part can be transformed and maintained in the shape it was in when medical image data was captured. For example, when the body part is a breast, the body part cover 200 is manufactured in a bra-like shape and can be worn on a patient during breast cancer surgery and then the surgery can be performed.

The customized surgical guide 10 according to an embodiment of the present invention is implemented in various forms depending on the intended use and can be used in various ways. In one embodiment, when the medical tool is a syringe with a specific needle length, the guide tube 100 is formed so that the syringe needle reaches the target point 40, and the target point 40 is a body part. It becomes a specific point on the surface of the treatment target area 20. That is, the customized surgical guide 10 is formed so that a specific point on the surface of the treatment target area 20 (i.e., the boundary between the treatment target area 20 and the normal area) becomes the target point 40. The plurality of target points 40 may be displayed as points on a plane corresponding to the boundary of the treatment target area 20, or may display a plurality of points on the three-dimensional space of the treatment target area 20, which has a three-dimensional shape. .

Specifically, as shown in Figure 3, a syringe filled with dye is inserted all the way into the customized surgical guide 10 until it reaches the target point 40, and then the syringe is withdrawn and the dye is discharged little by little to dye the inside of the body part. Through this, a dye pillar 30 is formed from the target point 40 within the body part to the first point on the surface of the body part.

As a plurality of staining pillars 30 are created through each guide tube 100 of the customized surgical guide 10, the exact removal area (i.e., treatment target area 20) can be identified. Even if the medical staff incises the affected area, the target point 40 of the staining pillar 30 exists continuously, so the point corresponding to the boundary of the treatment target area 20 can be confirmed during the surgical procedure.

In addition, in another embodiment, when the medical tool is a tool that performs treatment by setting a specific range as a treatment area from a specific point where the medical tool is inserted, the target point 40 encompasses the treatment target area 20. One or more specific points located within the treatment target area 20 form one or more of the treatment areas. In other words, the target point 40 that the medical tool reaches through the guide tube 100 becomes a specific point inside the treatment target area 20, and the medical tool is placed on the treatment area centered around the target point 40. Treatment is provided by providing electricity, etc.

At this time, the guide tube 100 is positioned on the first point of the body part cover 200 in the number of target points 40 in a direction from the first point to the target point 40. is formed If the treatment target area (20) is larger than the treatment area, the customized surgical guide (10) covers the treatment target area (20) by overlapping the treatment areas created around the target point (40) of each guide pipe (100). It is equipped with a certain number of guide tubes (100) that can be used. Through this, the medical staff can simply perform surgery by simply inserting a medical tool into the guide tube 100 that guides the patient to reach the target point 40 set according to the patient's surgery plan.

In addition, in another embodiment, the customized surgical guide 10 is formed of a material capable of changing shape, is inserted into the body through a laparoscope, and then placed on the surface of the body part. The customized surgical guide 10 can be placed on the surface of internal organs that are not exposed to the outside. For this purpose, the customized surgical guide 10 is made of a material capable of changing shape and is provided in a folded or rolled state to a specific body part inside the body through a laparoscope.

Additionally, in another embodiment, the guide tube 100 may be fitted with the medical tool when the end of the medical tool reaches the target point 40. Through this, the medical staff can recognize that the medical tool has reached the target point 40. For example, the guide tube 100 is formed to have a first diameter that only an injection needle can enter, and the end of the guide tube 100 is formed to have a second diameter that matches the syringe tip, so that the syringe tip is formed at the end of the guide tube 100. As it is inserted into the second diameter and can no longer enter the guide tube (100) of the first diameter, the medical staff recognizes that the target point (40) has been reached. In addition, in the case of a medical tool that needs to provide stimulation (for example, electrical stimulation) for more than a certain period of time by the target point 40, the fitting of the guide tube 100 allows the medical tool to reach the target point 40. Make sure it stays fixed.

Figure 4 is a flowchart of a method for creating a customized surgical guide 10 according to an embodiment of the present invention.

Referring to FIG. 4, the method of generating a customized surgical guide 10 according to another embodiment of the present invention includes the steps of a computer acquiring body surface data and treatment area data from medical image data (S100); A first shape data generation step (S300) of generating the first shape data based on the body surface data, wherein the first shape data is data corresponding to the shape of the body part cover 200; A target point setting step (S500) of setting one or more target points (40), wherein the target points (40) are points corresponding to the inside or surface of the treatment target area (20); Setting each first point on the body surface accessible to the medical tool as the target point 40 (S700); Setting the length of the guide tube 100 based on the distance from the first point to the target point 40 (S900); and applying the length of the guide pipe 100 to the first point to generate final shape data by combining one or more guide pipes 100 with the first shape data (S1100). Below, a detailed description of each step is described.

The computer obtains body surface data and treatment area data from medical image data (S100). That is, the computer acquires medical image data of a specific patient (for example, the patient's MR image), and the medical image data corresponds to body surface data and treatment target area 20 to form the body part cover 200. Acquire treatment area data. Specifically, when the treatment target area 20 is a tumor, the computer extracts the tumor area from medical image data.

The computer generates the first shape data based on the body surface data (S300; first shape data generation step). The first shape data is data corresponding to the shape of the body part cover 200. In other words, the computer performs 3D modeling in a shape corresponding to the surface of the patient's affected area. Through this, it is possible to manufacture a customized surgical guide (10) equipped with a body part cover (200) that fits the patient's body part.

Additionally, the computer sets a point on the first shape data corresponding to a specific point on the body surface data as the reference point 300. For example, if the body part to be treated (i.e., the affected part) is the breast, the computer forms a nipple hole 300 based on the nipple position on the body surface data, and forms a nipple hole 300 on the body of the customized surgical guide 10. It should be used as a standard when setting the placement position on the surface of the part.

In addition, in another embodiment, as shown in FIG. 7, the first shape data generating step (S300) includes acquiring overall shape data of the body part (S310); and generating a shape of the body part cover 200 that covers a specific body part based on the overall shape data (S320). In the case of a body part (e.g., breast) whose shape changes depending on posture, the entire body part must be covered and fixed in the shape at the time of medical image data acquisition to ensure accurate accuracy through a customized surgical guide (10) created based on medical image data. Surgery is possible. Therefore, the computer obtains the overall shape of the body part from medical image data and then models the body part cover 200 in a shape that covers the entire body part.

For example, MR imaging of the breasts of breast cancer patients is performed lying down, while breast cancer tumor removal surgery is performed lying down. Since the shape of the breast changes due to the difference in posture between MR imaging and surgery, the location of the tumor inside the breast also changes. In order to accurately mark the tumor area inside the body with staining, the breast shape must be fixed and maintained in the shape of the breast at the time of medical imaging data during surgery. Therefore, the computer models the breast in a shape that covers the entire breast, and when it is ejected and used in surgery, the breast is placed within the body part cover 200 to maintain the shape of the breast during MR imaging.

According to still other embodiments, breast cancer tumor removal surgery on breast cancer patients may be performed in a supine position (first position), and MRI imaging of the breast may also be performed in a supine position. Since the shape of the breast may change due to slight differences in posture during MRI imaging and surgery, the location of the tumor inside the breast also changes. In order to accurately mark the tumor area inside the body with staining, the breast shape must be fixed and maintained in the shape of the breast at the time of medical imaging data during surgery. Therefore, the computer models the breast in a shape that covers the entire breast, and when it is injected and used in surgery, the breast is placed within the body part cover 200 to maintain the shape of the breast when taking an MRI image.

The computer sets one or more target points 40 (S500; target point setting step). The target point 40 is a point corresponding to the inside or surface of the treatment target area 20. Specifically, the computer models the treatment target area 20 (i.e., removal area) based on the calculated target area (eg, tumor area) and considering the error range. Thereafter, the computer extracts one or more points inside or on the surface of the treatment area 20 as the target point 40.

In one embodiment, when the medical tool is a syringe with a specific needle length, the target point 40 is set to a specific point on the surface of the treatment target area 20. That is, the target points 40 are points on the interface containing tissue (i.e., tumor tissue) to be removed through surgery.

In addition, in another embodiment, when the medical tool is a tool that performs treatment with a specific range as the treatment area from the point of a specific depth into which the medical tool is inserted, the target point 40 is a specific point within the treatment target area 20. In the target point setting step (S500), one or more target points (40) are set to form one or more treatment areas encompassing the treatment target area (20). That is, the computer extracts a plurality of treatment areas using specific medical tools that can cover the treatment target area 20, and extracts a plurality of target points 40 where medical tools to form each treatment area should be placed. do.

The computer sets each first point on the body surface accessible to the medical tool as the target point 40 (S700; first point setting step). For example, if the treatment target area 20 is a tumor area, the computer determines a position (i.e., three-dimensional position) on the surface of the body part where a needle can be injected into the border of the tumor area.

In addition, when the target point 40 is set at the boundary between the treatment target area 20 (i.e., removal area) and the normal tissue area, the computer reaches the target point 40 without passing through the treatment target area 20. If possible, establish a first point that provides a path for medical equipment. For example, when the treatment target area 20 is a tumor area, when a medical tool (for example, a syringe needle) is inserted and passes through the tumor area to reach the target point 40 from the skin surface, the tumor area As this damage occurs, cancer cells can spread to other parts of the body. Accordingly, the computer extracts the first point that allows the medical tool to be inserted into the target point 40 without penetrating the treatment target area 20. To this end, in the case of a point located deep inside the body of the treatment target area 20, a first point accessible to the medical tool through the lateral direction is set.

Additionally, the computer sets the placement angle of the guide tube 100 according to the position of the first point set with respect to the target point 40. For example, when the medical tool has a straight line, the guide pipe 100 is formed in the direction of an extension of a straight line connecting the target point 40 and the first point. Through this, the medical staff simply inserts the medical tool along the guide tube 100 and the medical tool is inserted into the target point 40.

The computer sets the length of the guide tube 100 based on the distance from the first point to the target point 40 (S900; guide tube 100 length setting step). The computer forms the guide tube 100 with a length that limits the depth at which the medical tool can be inserted into the body to a set depth from the first point to the target point 40. For example, when the medical tool is a syringe equipped with an injection needle, the guide tube 100 is used to ensure that the needle enters only a certain depth into the body. After the needle is inserted into the guide tube 100, the syringe is inserted into the guide tube 100. It is formed to take (100). That is, if the length of the injection needle is A and the length of the guide tube 100 is B, as the syringe is caught in the guide tube 100, the needle enters the body only by the length corresponding to 'A-B'. . Therefore, the computer calculates the value based on the length of the medical tool and the distance between the target point 40 and the first point (i.e., the difference between the length of the medical tool and the distance between the target point 40 and the first point). ) Set the length of the guide pipe 100.

The computer applies the length of the guide pipe 100 to the first point and generates final shape data by combining one or more guide pipes 100 with the first shape data (S1100; final shape data generation step). That is, the computer generates final shape data in which the shape data of one or more guide pipes 100 are combined with the shape data of the body part cover 200 at a specific point at a specific length and angle. That is, the computer models the guide pipe 100 by adjusting the length of each pillar so that the needle can accurately reach the arm boundary in the depth direction when inserted.

The guide tube 100 of the customized surgical guide 10 formed through this process performs various roles. In one embodiment, when the medical tool is a syringe with a specific needle length, the guide tube 100 provides dye to the body by withdrawing the syringe after the syringe needle reaches the target point 40. It serves to assist in creating the pillar 30. In addition, in another embodiment, the guide tube 100 serves to increase surgical accuracy by allowing the medical tool to accurately reach the target point 40 where treatment is to be performed according to the surgical plan.

In addition, in another embodiment, as shown in FIG. 5, when the first posture in which the medical image data is captured and the second posture during surgery are different, the treatment target when changing from the first posture to the second posture It further includes calculating a change in position of the area 20 (S200). When taking medical image data in a position for performing surgery, modeling of the customized surgical guide 10 can be performed based on the medical image data. However, there may be cases where the position in which medical images are taken and the position during surgery are different. At this time, in order to create a customized surgical guide 10 that matches the second posture, which is the posture during surgery, a customized surgical guide (10) that matches the second posture during surgery is based on medical image data captured in the first posture. In order to produce 10), the computer calculates the change in position of the treatment target area 20 when the user's body part changes from the first posture to the second posture.

For example, among body parts, the breast changes its shape fluidly depending on posture. When taking MR images, the images are taken lying down (i.e., the MR images are taken in the first position), and the surgery is performed while lying down (i.e., the surgery is performed in the second position), so when taking MR images and during the surgery, Breast shape changes. As the breast shape changes, the three-dimensional spatial location of the tumor tissue within the breast also changes. Therefore, the computer determines the shape of the breast in the second posture based on the size of the breast, the shape in the first posture, etc., and the location of the tumor within the breast shape in the second posture (i.e., the location of the treatment target area 20). ) is calculated.

In addition, when modeling a customized surgical guide 10 that matches the second posture after shooting a medical image in the first posture, the target point setting step (S500), the first point setting step (S700), and the The guide tube 100 length setting step (S900) is performed based on the changed location of the treatment target area 20.

In addition, in another embodiment, the first shape data generation step (S300) calculates the shape of the body part in the second posture based on medical image data acquired in the first posture, and calculates the shape of the body part in the second posture based on the calculated deformed shape. Model the shape data (i.e., first shape data) of the body part cover 200.

In addition, in another embodiment of the present invention, when the medical tool is curved with a specific curvature, the computer generates the guide tube 100 with the same curvature as the medical tool. There may be cases where it is difficult to reach the target point 40 in the body with a straight medical tool, and in this case, a curved medical tool can be used. In order to insert a curved medical tool with a specific curvature into the body through a customized surgical guide (10), the guide tube (100) must be manufactured with the same curvature as the medical tool to enable smooth insertion, and the exact target point in the treatment plan Medical tools can reach (40).

In addition, in order to model the guide tube 100 for inserting a curved medical tool, the first point setting step 700 determines that the target point 40 can be reached when moving inside the body with the curvature. Extract the first point. That is, the computer extracts a first point that can reach the target point 40 when moving with a specific curvature, rather than a first point that can reach the target point 40 in a straight line.

Additionally, in the final shape data generation step (S1100), the curvature of the guide tube 100 is created to be the same as the curvature of the medical tool. Then, the curved length of the guide tube 100 is calculated by subtracting the distance that the medical tool must move along the curve within the body from the length of the medical tool.

In addition, as shown in FIG. 6, another embodiment of the present invention further includes requesting injection of final shape data (S1200). In other words, the computer requests injection of the modeled final shape data to a 3D injection device (i.e., 3D printer).

Figures 8A to 8C are diagrams showing a surgical guide 900 according to another embodiment of the present invention. Figure 8A is a perspective view, Figure 8B is a front view and Figure 8C is a side view.

Figures 9A and 9B are diagrams showing a surgical guide 900 according to another embodiment of the present invention, where Figure 9A is a front view and Figure 9B is a side view.

The surgical guide 900 of the present invention serves as a guide to visually determine the surgical area including the lesion area 1001 of the breast before surgery and includes a body part cover 902, a marking guide unit 907, and an alignment standard. It may include a unit 901 and an alignment guide unit 906.

The body part cover 902 is a member that is seated on the body part where the treatment area 1003 is located and may have a shape corresponding to the surface shape of the body part. Since the body part of the present invention is the breast, it may have a curved shape as shown in FIG. 8A. It is not necessary to cover the entire breast, which is the surgical site, and can be partially located in the area including the treatment site (1003) where the lesion occurred.

The body part cover 902 may be configured in a mesh form with a plurality of holes as shown in FIG. 8A. The operator's field of view can be secured through the hole in the mesh, and it can be confirmed whether the body part cover 902 is in close contact with the body part without lifting. Although the expression mesh is used, the size of the hole is not small and can be 1 to 2 cm or more.

In addition, the mesh structure of the body part cover 902 reduces the weight of the product, shortens the manufacturing time, and saves materials, thereby lowering the unit price of the product.

The body part cover 902 according to the embodiment is, for example, attached to the body part cover 902 so that a hook wire (not shown) for marking the target point or marking the removal area is not pressed by the body part cover 902. For example, it may be formed in a mesh-type structure to provide a hole through which the hook wire can pass.

A typical mesh structure has many holes in it, so the support factor may be low. The body part cover 902 according to embodiments may be formed in a honeycomb structure, which is a mesh structure with a high support ratio that maintains the shape of the product itself.

The body part cover 902 of the present invention includes a marking guide portion 907 to mark the surgical area to be removed by surgery. The surgical area includes a treatment area 1003, which is an area on the skin corresponding to the lesion area 1001. The lesion area 1001 can be removed by making an incision from the treatment area 1003 toward the lesion area 1001. To prevent recurrence, the surgical area can be formed slightly larger than the treatment area (1003).

The marking guide unit 907 may include a plurality of marking holes 9071 formed along the outer edge of the surgical area. The marking hole 9071 may extend long along the border of the surgical area as shown in FIG. 8B.

The marking hole 9071 may have a partially broken shape 9072 so as not to be separated from the body part cover 902, and the operator may insert the first medical tool, a medical pen, into the marking hole 9071. It can be inserted and mark the surgical area on the surface of the patient's body part along the extension direction of the marking hole (9071).

The marking hole 9071 may have a width corresponding to the thickness of the nib of a medical pen and extend along the surgical area.

A guide pipe 909 may be disposed between the plurality of marking holes 9071. The guide tube 909 is a means for marking the surgical area up to the inside of the body part where the second medical tool 820 is inserted. If the marking guide part 907 functions to mark the surgical area on the surface, the guide tube 909 ) can display a three-dimensional boundary.

The second medical tool 820 may be a syringe 820 for injecting medical ink 823, and the inner width of the guide tube 909 is larger than the diameter of the needle 821 of the syringe 820 and the main body of the syringe 820. It may have a shape smaller than the diameter of.

However, depending on the operator, if the second medical tool 820 is not used, the guide tube 909 can be omitted and a surgical guide 900 with the guide tube 909 omitted can be manufactured as shown in FIGS. 9A and 9B. You can.

The inside of the marking guide portion 907 may have a solid shape. Since the body part cover 902 is in a mesh form, it can be partially solid without holes for overall rigidity. In particular, since the guide tube 909 protrudes three-dimensionally from the body part cover 902, rigidity is required to maintain the angle at which the guide tube 909 protrudes from the body part cover 902, so the inside of the marking guide part 907 is It can be constructed solidly.

Figures 10A and 10B are diagrams showing the safety boundary range 1008 for setting the marking guide portion 907 of the surgical guide 900 according to another embodiment of the present invention.

As shown in FIG. 10A, the lesion area 1001 is located inside the skin, and the portion extending vertically from the lesion area 1001 on the skin closest to the lesion area is the treatment area 1003.

However, if only the treatment area (1003) where the lesion area (1001) is located inside is surgically removed, there is a risk of recurrence if the lesion cells (1001) spread to surrounding tissues.

Therefore, the safety boundary range 1008 can be calculated to be slightly larger than the treatment area 1003 and the surgical area can be determined. The safety boundary range 1008 can be set to be approximately 3 mm to 10 mm (5 mm in the embodiment of FIG. 10B) at the treatment area 1003, which is the area on the skin where the lesion area 1001 is located.

At this time, the difference between the treatment area 1003 and the safety boundary range 1008 may vary depending on the size, depth, etc. of the lesion area 1001.

As shown in Figure 10B, the safety boundary range 1008 can be set as a surgical area and the marking guide unit 907 can be designed along the outline of the safety boundary range 1008. Depending on the embodiment, when injecting medical dye through the above-described guide tube 909, a separation distance of about 5 mm may be left from the outermost line of the treatment area to mark so that a further area can be removed. When the ink 823 spreads, the ink may spread about 5 mm on each side from the marking line. Therefore, the thickness of the marking line may be 10 mm. Considering this, mark along an outline spaced at least 5 mm outward from the treatment target area, and considering the spread of this marking line, the body part can be removed by performing surgery along the outer midline of this marking line.

As shown in Figure 10B, the safety boundary range 1008 can be set as a surgical area and the marking guide unit 907 can be designed along the outline of the safety boundary range 1008. When injecting medical dye through the above-described guide tube 909, when the ink 823 spreads, an ink column with a thickness of approximately 3-5 mm is formed, and considering the thickness of the medical pen, the stable boundary range 1008 is formed. It can be designed so that the central part of the marking guide part (8907) and the guide tube (909) is located slightly inside by about 2 to 3 mm.

The surgical guide 900 must be placed in the correct position on the patient's body to accurately mark the surgical area. Therefore, the surgical guide 900 can set a reference point by determining a specific point on the body that serves as a reference.

Figures 11A to 11C are diagrams showing a modeling process for designing a surgical guide 900 according to another embodiment of the present invention.

It shows a method of designing an alignment reference portion 901 and an alignment guide portion 906 for seating the surgical guide 900 on a body part based on the main reference point and sub reference point.

Although the reference point may be different depending on the surgical site, this embodiment is explained based on the surgical guide 900 for removing the lesion site in the breast. The reference point can be the nipple of the breast where the surgical area where the lesion occurred is located as the primary main reference point (801).

Since the main reference point 801 is located on the surgical guide 900, an alignment reference portion 901 can be formed on the body part cover 902. The main reference point 801 of the alignment reference unit 901 may have a hole shape into which a nipple can be inserted. The body part cover 902 covers the surgical area including the nipple, and as shown in Figure 11A, the surgical area may be located directly below the nipple, or as shown in Figures 11B and 11C, even if the surgical area is located at a distance from the nipple, the surgical area may be located at a distance from the nipple. The area cover 902 may extend to the nipple location.

However, since the nipple is one point, a plurality of reference points are required to set an accurate surgical area, and in addition to the main reference point (801), sub reference points (802, 803) can be additionally set. In breast surgery, the nipple point of the breast other than the breast where the surgical area is located is used as the sub-reference point (802, 803) as the first sub-reference point (802), and the jugular notch point is used as the second sub-reference point (803). You can do this.

The sub-reference points 802 and 803 are separated from the breast, which is the surgical area, so it is difficult to directly display the positions of the sub-reference points 802 and 803 on the body part cover. Instead, as shown in FIG. 11A, an alignment guide portion 906 may be formed corresponding to extension lines 807 and 808 extending from the main reference point 801 toward the sub reference points 802 and 803.

As shown in FIG. 11A, the alignment guide unit 906 may include a long bar-shaped member on the body part cover 902, and if the body part cover 902 is made of a solid material, an extension line 807, It can also be configured in the form of a slit formed along 808).

Since this embodiment is a mesh-type body part cover 902 with a honeycomb structure, it may include a bar-shaped alignment guide portion 906 that crosses the mesh. The first alignment guide unit 9061, where the first sub reference point 802 is directed to the other nipple, forms a horizontal direction when the body part cover 902 is seated on the body part, and is directed toward the clavicle point, which is the second sub reference point 803. The second alignment guide portion 9062 may be opened at a predetermined angle from the first alignment guide and may extend obliquely upward.

After the operator inserts the alignment reference portion 901 into the nipple of the surgical site, the alignment guide portions 906 and 9061 may extend toward the sub reference points 802 and 803.

The body part cover 902 does not need to cover the entire breast, but includes a marking guide portion 907 corresponding to the surgical area, alignment reference portions 901, 801 corresponding to the nipple, and alignment guide portions 906, 9061. It may be sized to have sufficient length to identify the positions of the sub-reference points 802 and 803.

Figures 12A to 12D are diagrams showing a method of using the surgical guide 900 of the present invention for breast cancer surgery.

Referring to Figure 12A, the nipple of the breast can be inserted into the alignment reference portion 901 and the body part cover 902 can be placed on the breast. Thereafter, the body part cover 902 is rotated and placed on the breast so that the first alignment guide portion 9061 is disposed toward the nipple on the other side and the second alignment guide portion 9062 is disposed toward the clavicle point. Afterwards, a marking line 1007 can be marked along the marking guide portion 907 on a body part using a medical pen. In addition to the marking line 1007 on the skin, the inside of the skin can be dyed using human ink 823 to mark the surgical area three-dimensionally.

Figure 12B shows a method of dyeing by injecting dye through a guide tube 909. As shown in FIG. 12B, the syringe 820 into which the ink 823 is injected can inject the ink 823 into the skin after inserting the needle 821 into the guide tube 909.

The length of the guide tube 909 can be set so that the injection needle 821 can reach the target point located around the lesion point. That is, the length of the guide tube 909 is the length of the injection needle 821 minus the distance from the skin to the target point.

With the injection needle 821 fully inserted into the guide tube 909, the ink 823 is injected little by little and the syringe 820 is pulled out little by little from the guide tube 909 to form a dyeing column.

When the surgical guide 900 is removed, the surgical area is displayed as shown in FIG. 12C. When the surgical area is incised and unfolded, the lesion area 1001 is exposed as shown in FIG. 12D, and the lesion area 1001 can be removed.

Figures 13 to 18 are flowcharts showing a method for producing a surgical guide 900 of the present invention.

Referring to Figure 13, the method of generating the surgical guide 900 of the present invention can model the shape on a computer using the surgical guide 900 program and then output it on a 3D printer. Since this is a surgical guide (900) customized for each patient, multiple pieces are not mass-produced, so it is easier to use a 3D printer than to manufacture it with a mold.

Referring to FIG. 13, we will look at a basic surgical guide 900 creation method.

A computer modeling program acquires body part surface data and data of the treatment area 1003 from medical image data (S2100). Medical imaging data refers to image data acquired through a medical imaging device (e.g., a computed tomography (CT) device, a magnetic resonance imaging (MRI) device, etc.).

First shape data of the body part cover 902 corresponding to the body part surface data can be generated (S2300). In the case of the surgical guide 900 for breast cancer surgery, the body part is the breast, and the shape of the breast varies depending on the patient's posture, so the surface data of the body part may also vary.

Therefore, available medical image data can be data taken in the same posture as the surgical posture, and the body part cover 902 can be created according to the first shape data having a curved surface corresponding to the shape of the body part surface.

However, if the patient's posture at the time the medical image data is captured is not the same as the surgical posture, the surgical posture is modeled based on the positional changes of reference points and the shape change due to the density of the breast tissue based on the medical image data, as shown in Figure 14. The converted body part surface data and treatment target area data can be calculated (S2200).

The safety boundary range 1008 including the treatment area 1003 is calculated to generate second shape data corresponding to the safety boundary range 1008 (S2400). The second shape data is the data of the marking guide unit 907, and as described in FIG. 10, a safety boundary range 1008 larger than the treatment area 1003 can be calculated and the shape of the marking guide unit 907 can be designed according to this. there is.

The second shape data includes a plurality of marking holes (9071), and the length and number of marking holes (9071) are determined according to the size of the treatment area (1003) and the width of the marking hole (9071) is determined considering the width of the medical pen. By determining the second shape data, it is possible to generate the second shape data.

Surgical guide 900 data can be generated by merging the first shape data and the second shape data to model the body part cover 902 on which the marking guide portion 907 is formed (S2800).

According to the flowcharts of FIGS. 13 and 14, the surgical guide 900 on which the marking guide portion 907 is formed can be produced.

According to the flowchart of FIG. 15A, third shape data corresponding to the alignment reference unit 901 can be generated at a position corresponding to the main reference point 801 on the body part (S2500). The main reference point 801 is the nipple of the breast in the surgical area, and the third shape data is data of the hole-shaped alignment reference portion 901 located on the nipple.

The body part cover 902 on which the marking guide portion 907 and the alignment reference portion 901 are formed can be modeled (S2810) by merging the first shape data and the third shape data.

It may further include generating fourth shape data for the alignment guide unit 906 indicating the positions of the sub-reference points 802 and 803, as shown in FIG. 15B. Fourth shape data of the alignment guide unit 906 connecting the sub-reference points 802 and 803 located on other body parts and the main reference point 801 is generated (S2600).

The sub-reference points (802, 803) include at least one of the nipple or clavicle point of the other breast, and the fourth shape data is a bar-shaped bar extending across the body part cover 902 toward the sub-reference points (802, 803). It's data.

The body part cover 902 on which the marking guide part 907, the alignment reference part 901, and the alignment guide part 906 are formed can be modeled by merging the first to fourth shape data (S2820).

If it is desired to manufacture a surgical guide 900 including a guide tube 909 as shown in FIG. 8A, step S2700 of FIG. 16 can be additionally performed.

It is located between the plurality of marking holes 9071 and the fifth shape data of the guide tube 909 into which the second medical tool 820 is inserted can be generated (S2700). The fifth shape data may include data on the location and number of guide pipes 909 and the length of the guide pipes 909.

The body part cover 902 on which the marking guide portion 907 and the guide tube 909 are formed can be modeled by merging the first shape data, second shape data, and fifth shape data (S2830).

The method of generating a customized surgical guide 10 according to an embodiment of the present invention described above may be implemented as a program (or application) and stored in a medium in order to be executed in combination with a computer, which is hardware.

The above-mentioned program is C, C++, JAVA, machine language, etc. that can be read by the processor (CPU) of the computer through the device interface of the computer in order for the computer to read the program and execute the methods implemented in the program. It may include code coded in a computer language. These codes may include functional codes related to functions that define the necessary functions for executing the methods, and include control codes related to execution procedures necessary for the computer's processor to execute the functions according to predetermined procedures. can do. In addition, these codes may further include memory reference-related codes that indicate at which location (address address) in the computer's internal or external memory additional information or media required for the computer's processor to execute the above functions should be referenced. there is. In addition, if the computer's processor needs to communicate with any other remote computer or server in order to execute the above functions, the code uses the computer's communication module to determine how to communicate with any other remote computer or server. It may further include communication-related codes regarding whether communication should be performed and what information or media should be transmitted and received during communication.

The storage medium refers to a medium that stores data semi-permanently and can be read by a device, rather than a medium that stores data for a short period of time, such as a register, cache, or memory. Specifically, examples of the storage medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc., but are not limited thereto. That is, the program may be stored in various recording media on various servers that the computer can access or on various recording media on the user's computer. Additionally, the medium may be distributed in a computer system connected to a network, and computer-readable code may be stored in a distributed manner. According to the present invention as described above, various effects are achieved as follows.

First, by using a customized surgical guide (10) that assists in performing surgery tailored to the patient, the optimal surgery for the patient can be performed. For example, when a surgical lesion (e.g., a tumor) within the affected area needs to be removed, one or more staining pillars 30 are created within the body part using the patient-customized surgical guide 10, so that the removal area can be maintained even during surgery. There is an effect that can be visually confirmed. Through this, medical staff can treat by removing a minimum amount of tissue through two-dimensional or three-dimensional marking through the dye pillar 30.

Second, the surgical guide 900 can be aligned in the correct position based on the reference point of the body part, allowing the accurate surgical area to be displayed. Even if the sub-reference point is located outside the surgical guide 900, the position can be aligned through the alignment guide unit 906, and a sufficiently accurate surgical area can be displayed even with a small-sized surgical guide 900.

Third, the operator's field of view can be secured by forming the body part cover 900 only in necessary areas. In addition, manufacturing costs can be reduced, lowering unit costs and shortening manufacturing times.

Fourth, since the guide tube 100 is created by calculating the depth to the target point 40 based on medical image data, the medical staff performs surgery without worrying about the depth at which medical tools (e.g., syringes) are inserted. can do. In other words, if the medical tool is inserted all the way into the guide tube 100 of the custom-fit surgical guide, the target point 40 is reached, which allows the surgery to be performed easily.

Fifth, by manufacturing the body part cover 200 to correspond to the shape of the body, the guide tube 100 can be placed at a point where it can accurately reach the target point 40 when inserting a medical tool. Through this, it is possible to prevent treatment from being performed at the wrong target point 40 or incorrect marking within a body part.

Above, embodiments of the present invention have been described with reference to the attached drawings, but those skilled in the art will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. You will be able to understand it. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
