Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a display board for operation-related information and a method for displaying operation-related information. Background Art

[0002] Before starting an operation, surgeons hope to obtain information about the patient to be operated on more conveniently and intuitively. This information includes the patient's medical history, preoperative examination report, preoperative imaging, etc., and further, obtain more intuitive information about the location of the target surgical lesion in the body.

[0003] At present, doctors can only make a comprehensive analysis based on their memory, understanding and experience after reading two-dimensional graphics on a film or computer screen before surgery. If there is a tool that can accurately and intuitively display this information, it will be possible to significantly reduce the difficulty of surgical operations and reduce the training or surgical experience requirements for surgeons; further, if the location of the lesion, the surrounding tissue structure of the lesion, and the actual location of the patient's body can be more accurately associated, surgeons may no longer need to expose the lesion in front of their eyes before performing surgery, but only rely on minimally invasive interventional surgical tools, aiming at the accurate lesion location displayed, and perform some surgical operations.

[0004] In order to display this information, in addition to more convenient display devices, it is also necessary to rely on surgical information display boards associated with patients, especially the accurate display of lesion location information, which requires the accurate combination of patient imaging, body surface markers (feature points) and optical recognition patterns. At the same time, because the surgical operating room and the imaging scanning room are not together, some surgical interventions cannot be performed in the imaging room. Patients need to go in and out of bed repeatedly, and even some daily activities before starting surgery. This makes the repeated positioning of the display board one of the problems that need to be solved.

[0005] In view of this, there is an urgent need to provide a surgery-related information display board and a surgery-related information display method that can accurately display surgery-related information related to the patient and can be accurately positioned on the patient's body surface to assist the surgery.

[0007] Exemplarily, the information display portion includes a pattern information sticker affixed to the upper surface of the plate body, and a QR code-like code is printed on the pattern information sticker.

[0032] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0033] The surgery-related information display board provided by the present invention is mainly used for surgeons to intuitively obtain information about patients undergoing surgery before starting the operation. This information includes the patient's medical history, preoperative examination report, preoperative images, and the location of the target surgical lesion in the body.

[0034] Combined with reference Figures 1 to 6 The surgery-related information display board includes a base 10 and a board body 20, the base 10 has a positioning portion 11 and a connecting portion 12, the board body 20 has a connecting area 21 and a feature display area 22; wherein the positioning portion 11 is positioned on the human body surface; the connecting area 21 is connected to the connecting portion 12; the feature display area 22 has an information display portion 221 based on an image feature structure, an optical feature structure and a body surface feature structure.

[0035] In the existing medical field, image feature structures, optical feature structures, and body surface feature structures are common. In the present invention, the image feature structures, optical feature structures, and body surface feature structures are mainly applied to display of operation-related information so that surgeons can intuitively obtain information about the patient to be operated on before starting the operation.

[0036] The following is a brief explanation of the terms image characteristic structure, optical characteristic structure and body surface characteristic structure.

[0037] Image feature structures include: metal pieces, metal balls, iodine-containing liquids, etc. visible in X-ray, CT, and ultrasound; magnetic ion solutions (Fe, Gd, etc.) visible in MR, points, pieces, balls, etc. composed of materials such as glycerol. After the image feature structure is recognized by the imaging device, no less than 3 spatial coordinate positions can be extracted for coordinate transformation.

[0038] In order to facilitate identification, the image feature structure can be arranged in a non-repeating manner, that is, any adjacent feature structure area extracted in more than one row or more than one column will not be repeated in other positions in the entire arrangement. For example, Figure 1 The operation-related information display board shown in FIG. 1 has multiple image feature structures 31 thereon. Figure 2 The arrangement shown in the figure, where "1" indicates the position of the image feature structure 31, and "0" indicates an empty position. This arrangement method can ensure that even if the image scan only scans a local area of ​​the image plate, the three-dimensional coordinate information that can be aligned to the entire image space can be obtained. The method of scanning a row or a column of points to obtain three-dimensional feature points relies on the spatial structure of the feature points themselves, such as a round piece, a long column, etc., and cooperates with their arrangement information to obtain the corresponding three-dimensional space information.

[0039] The optical characteristic structure is a characteristic structure that can be identified as no less than three spatial coordinate positions after the optical imaging device captures the pattern. Based on the optical characteristic structure, the three-dimensional coordinate information of the space corresponding to the optical pattern can be determined for coordinate transformation; the optical characteristic structure can be a static pattern generated by printing / printing or a variable pattern displayed by a display (LED / EPD dot matrix electronic paper, etc.).

[0040] The surface characteristic structures are surface anatomical marking points, such as nipples, facial features, joints, bones, etc. They can also be artificially added characteristic patterns, such as areas or points outlined on the body surface with a surgical marker, or image characteristic points artificially pasted on the body surface, etc. The surface characteristic structures are spatial characteristic marks throughout the CT scan and the surgical operation process.

[0041] See again Figure 1 In one embodiment of the present invention, the plate body 20 is a hollow plate body having multiple hollows formed by a cross in the feature display area 22, and an image feature structure 31 is fixed at the center of the cross. The image feature structure 31 is a structural feature that can be captured and identified by an optical imaging device with no less than 3 spatial coordinate positions, that is, the image feature structure 31 is also an optical feature structure.

[0042] Based on this structural setting, the image feature board used in the imaging room can be used as a display board for surgical related information at the same time, that is, the image feature board used in the imaging room and the display board for surgical related information are the same product. Since a lasting mark can be left on the patient's surface during scanning in the imaging room, such as outlining the periphery of the image feature board, leaving an indentation with a protruding design on the bottom surface, or further attaching a medical colorant (such as gentian violet, etc.) on the surface of the protruding structure, the colorant leaves a mark on the skin surface, and it can be maintained from the time of scanning the image until the start of the operation. Or it can be associated with the inherent surface characteristic structure of the human body (such as 5mm from the corner of the eye, 10mm from the tip of the nose, or 20cm and 15cm from the two nipples, etc.). Before the operation, the patient is kept in the same position as when scanning the CT (such as both in the supine position or both in the lateral position), and the surgical related information display board is repeatedly fixed, and the characteristic points on the skin surface are compared, so that it is repeatedly fixed to the position when the CT scan is performed. At this point, the optical positioning information can be guaranteed to be consistent with the three-dimensional image information.

[0043] The surgical information display board of this embodiment is suitable for the situation where the surgical operation is performed in the imaging room and the patient does not need to repeatedly get on and off the bed. The surgical information display board is quickly positioned by optical recognition, so that the image feature point position information integrated with it can be quickly converted to the actual space where the patient is located. Subsequently, the lesion position can be quickly displayed in the actual space through augmented reality display, three-dimensional projection and other methods.

[0044] In another embodiment of the present invention, when the image characteristic structure on the image characteristic plate used in the image room is not an optical characteristic structure, Figure 3 The feature display area 221 also has a plurality of observation alignment holes 40, which penetrate from the upper surface of the plate body 20 to the lower surface of the plate body 20. At this time, the image feature board used in the imaging room and the surgery-related information display board are two independent products, but the main dimensions of the appearance are consistent (such as the length of the plate body 20 is L, the width is W), the fixing method is consistent, and they are used in the imaging room and the operating room respectively.

[0045] The operation-related information display board in this embodiment is used in the following manner: when scanning in the imaging room, a permanent mark is left on the patient's surface, such as outlining the periphery of the image feature board, leaving an indentation with a protruding design on the bottom surface, or further attaching a medical colorant (such as gentian violet, etc.) to the surface of the protruding structure, and the colorant leaves a mark on the skin surface, which can be maintained from the time of scanning the image to the start of the operation. Or it is associated with the inherent surface characteristic structure of the human body (such as 5mm from the corner of the eye and 10mm from the tip of the nose, or 20cm and 15cm from the two nipples, etc.). Before the operation, the patient is kept in the same position as when scanning CT (such as both in the supine position or both in the lateral position), and more alignment is made with the surface marks left in the imaging room based on the image feature board through the observation alignment hole 40 on the surface of the information board in the operating room, so as to improve the repeatable positioning accuracy of the operation-related information display board. In this way, the positioning can be repeated quickly, and spatial positioning can be achieved with only one optical recognition. The operation-related information display board in this embodiment is suitable for clinical needs that are different from the operating room and the imaging room, and have high requirements for positioning speed and low requirements for accuracy.

[0046] Further, see Figure 5 The information display portion 221 of the surgery-related information display board of the above two embodiments can further include a pattern information sticker affixed to the upper surface of the board body 20, and a QR-like code 32 (the QR-like code 32 is an optical characteristic structure) is printed on the pattern information sticker. The QR-like code 32 stores the information of the patient to be operated on, and the information of the patient to be operated on can be obtained by scanning the QR-like code 32.

[0047] Furthermore, Figure 6 As shown, the pattern information sticker may also be printed with prompt information 33, which is arranged on both sides of the quasi-QR code 32. The prompt information 33 may be, for example, name, age, gender, placement direction (head, foot), lesion location, etc. Furthermore, the center of the information display portion 221 has an optical characteristic hole 322, which is also an optical characteristic structure.

[0048] See again Figure 4 In order to facilitate the adjustment of the operation-related information display board, the connecting part 12 is rotatably connected to the positioning part 11 through a universal joint. In this way, the plate body 20 can be flipped relative to the base 10 to expose the patient's body surface covered thereunder, so that the doctor can perform skin disinfection, puncture and other surgical treatment steps on the puncture area. After the treatment is completed, the plate body 20 can be folded back again for re-positioning.

[0049] According to another aspect of the present invention, there is also provided a method for displaying surgery-related information, comprising the following steps:

[0050] S100, acquiring image characteristic structures, optical characteristic structures and body surface characteristic structures;

[0051] S200, fixing the above-mentioned operation-related information display board on the body surface;

[0052] S300, adjusting the position of the surgery-related information display board based on the image characteristic structure, the optical characteristic structure and the body surface characteristic structure, and positioning the surgery-related information display board;

[0053] S400, displaying the operation-related information through the information display unit.

[0054] The following describes in detail the method for displaying surgery-related information in conjunction with the surgery-related information display boards of the two different embodiments described above.

[0055] When the imaging feature board used in the imaging room and the surgical related information display board are the same product, the surgical related information display method includes:

[0056] Step S100, obtaining the image characteristic structure, the optical characteristic structure and the body surface characteristic structure. Specifically, the image characteristic structure on the image characteristic plate used in the imaging room is obtained; at the same time, when scanning in the imaging room, a permanent mark (i.e., body surface characteristic structure) is left on the patient's surface, such as outlining the periphery of the image characteristic plate, leaving an indentation with a protruding design on the bottom surface, or further attaching a medical colorant (such as gentian violet, etc.) on the surface of the protruding structure, and the colorant leaves a mark on the skin surface, which can be maintained from the time of scanning the image until the start of the operation. Or, it also includes step S102, marking on the body surface to reflect the position of the image characteristic structure, so as to associate it with the inherent body surface characteristic structure of the human body (such as 5mm from the corner of the eye and 10mm from the tip of the nose, or 20cm and 15cm from the two nipples respectively).

[0057] Step S200, fix the above-mentioned operation-related information display board on the body surface. Specifically, before the operation, the patient maintains the same body position as that during the CT scan (such as supine position or lateral position), and the operation-related information display board is fixed on the body surface through the positioning unit 11.

[0058] In step 300, the position of the image feature structure is identified by an optical imaging device to locate the display board of the operation-related information. The display board of the operation-related information is repeatedly fixed and the feature points on the skin surface are compared so that it is repeatedly fixed to the position during the CT scan. At this point, the optical positioning information can be ensured to be consistent with the three-dimensional image information.

[0059] S400, the information display unit displays the operation-related information. Specifically, since the image feature structure 31 is a structural feature that can be collected and identified by an optical imaging device with at least three spatial coordinate positions, the lesion position can be quickly displayed in the actual space through an augmented reality display, three-dimensional projection, etc. Of course, the operation-related information can also be displayed by scanning the QR code 32 printed on the pattern information sticker attached to the upper surface of the plate 20.

[0060] When the image feature board used in the imaging room and the surgery-related information display board are different products, the surgery-related information display method includes:

[0061] Step S100, obtaining the image characteristic structure, the optical characteristic structure and the body surface characteristic structure. Specifically, the image characteristic structure on the image characteristic plate used in the imaging room is obtained; at the same time, when scanning in the imaging room, a permanent mark (i.e., body surface characteristic structure) is left on the patient's surface, such as outlining the periphery of the image characteristic plate, leaving an indentation with a protruding design on the bottom surface, or further attaching a medical colorant (such as gentian violet, etc.) on the surface of the protruding structure, and the colorant leaves a mark on the skin surface, which can be maintained from the time of scanning the image until the start of the operation. Or, it also includes step S102, marking on the body surface to reflect the position of the image characteristic structure, so as to associate it with the inherent body surface characteristic structure of the human body (such as 5mm from the corner of the eye and 10mm from the tip of the nose, or 20cm and 15cm from the two nipples respectively).

[0062] Step S200, fix the above-mentioned operation-related information display board on the body surface. Specifically, before the operation, the patient maintains the same body position as that during the CT scan (such as supine position or lateral position), and the operation-related information display board is fixed on the body surface through the positioning unit 11.

[0063] Step 300, optically identify the optical characteristic structure (observing the alignment hole 40 means looking at the optical characteristic structure. Of course, optical characteristic structures other than observing the alignment hole 40 may also be used, such as Figure 6 The optical characteristic holes 322 in the operating room are aligned with the positions of the image characteristic structures marked on the body surface, so as to position the operation-related information display board. Specifically, before the operation, the observation alignment holes 40 on the surface of the operating room information board are used to align more with the body surface marks left in the imaging room based on the image characteristic board, so as to improve the repeatability of the operation-related information display board.

[0064] S400 , displaying the operation-related information through the information display unit. Specifically, the operation-related information can be displayed by scanning the QR code 32 printed on the pattern information sticker attached to the upper surface of the plate 20 .

[0065] When the imaging room does not use imaging feature boards, the surgical information display methods include:

[0066] Step S100, obtaining the image characteristic structure, the optical characteristic structure and the body surface characteristic structure. Specifically, when the image characteristic structure is associated with the body surface characteristic structure, or when it is itself the body surface characteristic structure. For example, multiple metal sheets attached to the skin surface are used as CT image characteristic structures, and the perimeter of the metal sheet or the center of the metal sheet is outlined with a medical marker pen as the corresponding body surface characteristic structure, that is, the body surface characteristic structure is marked on the body surface based on the image characteristic structure. When the imaging examination is completed, the metal sheet is removed and the skin mark (i.e., the body surface characteristic structure) is retained.

[0067] Step S200, fix the above-mentioned operation-related information display board on the body surface. Specifically, before the operation, the patient maintains the same body position as that during the CT scan (such as supine position or lateral position), and the operation-related information display board is fixed on the body surface through the positioning unit 11.

[0068] Step 300, optically identify the optical characteristic structure multiple times, and align the optical characteristic structure with the body surface characteristic structure to locate the surgery related information display board. Specifically, after at least three or more optical characteristic structures (such as Figure 6 The optical characteristic holes 322 in the image are associated with the non-collinear skin marks on the body surface to achieve the registration of the space where the human body is located with the image space. In this way, relying on the precise matching of multiple optical characteristic structures with a single surface characteristic structure, a more accurate registration of the image space and the surgical space is achieved. However, because the optical characteristic structure needs to be recognized multiple times, it is more suitable for different clinical needs in the operating room and the imaging room, and has higher requirements for positioning accuracy.

[0069] S400 , displaying the operation-related information through the information display unit. Specifically, the operation-related information can be displayed by scanning the QR code 32 printed on the pattern information sticker attached to the upper surface of the plate 20 .
