[0039] The case part (111) can form a predetermined space on the inside.

[0040] The surgeon can perform endoscopic surgery while holding the above-mentioned case part (111).

[0041] For example, the case portion (111) may be formed by detachably joining two members, but the present invention is not limited thereto.

[0042] The case portion (111) may be formed such that the width of the middle portion is smaller than the width of the front portion and / or the width of the rear portion.

[0043] For example, the case part (111) may be in the shape of a Korean gourd.

[0044] For example, the length of the portion having the largest width at the front end of the case portion (111) and the portion having the largest width at the rear end of the case portion (111) may be 8 cm, but the present invention is not limited thereto.

[0045] For example, the case part (111) may be in the shape of Korean white porcelain or a jar.

[0046] This may be intended to make it easier for the surgeon to grasp the case part (111).

[0048] The shear fixing part (112) may be provided with a first shear fixing part (112a) extending from the case part, a second shear fixing part (112b) extending from the shear portion of the first shear fixing part (112a) having a predetermined angle with the first shear fixing part (112a), and a third shear fixing part (112c) extending from the shear portion of the second shear fixing part (112b) having a predetermined angle with the second shear fixing part (112b).

[0049] Additionally, the shear fixing part (112) may further include a shear reinforcement part (112d) extending downward from the shear part of the third shear fixing part (112c).

[0051] The first shear fixing part (112a) can be extended to protrude in a first direction from the shear part of the case part.

[0052] For example, the first shear fixing part (112a) may be in the shape of a square column, but the present invention is not limited thereto.

[0053] For example, the first direction may be the same direction as the length direction of the case portion (111), but the present invention is not limited thereto.

[0055] The second shear fixing part (112b) can be extended to protrude in a second direction from the shear portion of the first shear fixing part (112a).

[0056] Here, the second shear fixing part (112b) may be extended from the shear portion of the first shear fixing part (112a) so as to be located at a different height from the height of the first shear fixing part (112a).

[0057] For example, the second shear fixing part (112b) may be in the shape of a square column, but the present invention is not limited thereto.

[0058] The horizontal component (direction) of the second direction and the horizontal component (direction) of the first direction may have a predetermined angle.

[0059] For example, the angle formed by the horizontal component (direction) of the second direction and the horizontal component (direction) of the first direction may be 51°, but the present invention is not limited thereto.

[0060] The vertical component (direction) of the second direction and the vertical component (direction) of the first direction may have a predetermined angle.

[0061] For example, the angle formed by the vertical component (direction) of the second direction and the vertical component (direction) of the first direction may be 51.3°, but the present invention is not limited thereto.

[0062] Due to the direction in which the second shear fixing part (112b) extends, the surgeon can minimize the obstruction of the surgical field of view by the shaft part (120).

[0064] The third shear fixing part (112c) can be extended to protrude in a third direction from the shear part of the second shear fixing part.

[0065] For example, the horizontal component of the third direction and the horizontal component of the first direction may be in the same direction.

[0066] For example, the vertical component of the third direction and the vertical component of the first direction may be in the same direction.

[0067] That is, the third direction and the first direction may be the same direction.

[0068] The horizontal component of the third direction and the horizontal component of the second direction may have a predetermined angle.

[0069] For example, the angle formed by the horizontal component of the third direction and the horizontal component of the second direction may be 51°, but the present invention is not limited thereto.

[0070] The vertical component (direction) of the third direction and the vertical component (direction) of the second direction may have a predetermined angle.

[0071] For example, the angle formed by the vertical component (direction) of the third direction and the vertical component (direction) of the second direction may be 51.3°, but the present invention is not limited thereto.

[0072] The third shear fixing part (112c) may be located at a lower position than the first shear fixing part (112a).

[0073] A first fixing hole, which is a hole penetrating in the vertical direction, may be formed in the shear portion of the third shear fixing portion (112c).

[0074] The rear end of the above-mentioned placement part and the above-mentioned shaft part can be inserted into the first fixing hole to be combined and fixed.

[0075] The first fixing hole may be provided with a first-1 fixing hole (h112c-1) whose diameter widens toward the upper direction, and a first-2 fixing hole (h112c-2) located below the first-1 fixing hole and into which the rear end of the shaft portion is inserted.

[0076] The first fixation hole (h112c-1) may have a shape with a change in diameter to facilitate the operation of the surgical instrument inserted into the placement portion.

[0077] For example, the upper inner diameter of the first-1 fixing hole (h112c-1) may be 9.1 cm, but the present invention is not limited thereto.

[0078] The third shear fixing part (112c) may be formed so that the middle part is recessed in the width direction.

[0079] This may be intended to maximize the surgeon's field of vision.

[0081] The shear reinforcement part (112d) can be formed by protruding downward from the lower side of the shear portion of the third shear fixing part (112c).

[0082] The shear reinforcement part may have a second fixing hole (h112d) formed therein, which is a hole penetrating in the vertical direction.

[0083] The second fixing hole (h112d) can be connected to the first-second fixing hole (h112c-2).

[0084] The shaft portion (120) can be inserted into and fixed in the second fixed hole (h112d).

[0085] The shear reinforcement part (112d) can fix and support the shaft part (120) together with the third shear fixing part (112c).

[0087] The wire connecting part (114) can be inserted and placed in the lower hole of the rear end of the case part (111).

[0088] The wire mediating section (114) can have a camera wire (not shown), which is a wire connected to the camera section (140), and a main wire (not shown), which is a wire connected to a computing device that analyzes and displays image data captured by the camera section (140), connected to each other by the board section.

[0089] The wire mediating part (114) can surround and protect the camera wire and the main wire so that no other conductor or device other than the camera wire and the main wire is electrically connected.

[0090] The wire mediating part (114) can be made of an insulating material.

[0091] For example, the wire connecting part (114) may be made of rubber, but the present invention is not limited thereto.

[0092] In addition, power lines, other control lines, and data lines connecting the computing device and the board may exist inside the above-mentioned wire mediating part (114).

[0094] The water pipe mediating part (115) can protrude in a rearward direction from the rear end of the case part (111).

[0095] For example, the above-mentioned water pipe mediating part (115) may protrude from one side of the above-mentioned first case part (111a).

[0096] The water pipe mediating part (115) can form a predetermined space on the inside.

[0097] A water pipe through which water is moved can be arranged inside the water pipe mediating part (115).

[0099] The shaft portion (120) may have a hollow formed in the longitudinal direction.

[0100] For example, the shaft portion (120) may be in the shape of a hollow cylinder, but the present invention is not limited thereto.

[0101] The front portion of the shaft portion (120) can be extrapolated to the tip portion (130).

[0102] The shaft portion (120) can be inserted into the first fixing hole and the second fixing hole (h112d).

[0103] For example, the shaft portion (120) may be 12 cm, but the present invention is not limited thereto.

[0104] For example, the inner diameter of the shaft portion (120) may be 9 cm, but the present invention is not limited thereto.

[0106] The tip portion (130) may have a first tip portion (131) and a second tip portion (132) extending in one direction from the first tip portion (131).

[0107] The tip portion (130) may be provided with a first placement hole (h131) where a surgical tool (not shown) can be positioned, a second placement hole (h132) where the camera portion (140) can be positioned, a third placement hole (h133) where a light-emitting portion can be positioned, and a fourth placement hole (h134) into which a water pipe can be inserted and positioned.

[0108] In the tip portion, the third placement hole (h133) and the fourth placement hole (h134) may be formed on both sides based on the second placement hole (h132).

[0110] The first tip portion (131) may be cylindrical in shape.

[0111] However, not limited thereto, the shape of the first tip portion (131) can be varied in various ways that are obvious to a person skilled in the art.

[0112] The outer diameter of the first tip portion (131) may be larger than the outer diameter of the second tip portion (132).

[0113] The outer surface of the first tip portion (131) and the outer surface of the second tip portion (132) can form a step.

[0114] A plurality of holes penetrating in the longitudinal direction may be formed in the first tip portion (131).

[0115] The front surface of the first tip portion (131) may be formed to be inclined from the upper direction to the lower direction.

[0116] Specifically, the front portion of the first tip portion (131) may be composed of a first tip surface (S131a) having a first slope and a second tip surface (S131b) having a second slope that is different from the first slope.

[0117] The first tip surface (S131) ​​may be located above the second tip surface (S132).

[0118] The first tip surface (S131) ​​may have a gentler slope than the second tip surface (S132).

[0119] That is, the slope of the first slope may be smaller than the slope of the second slope.

[0120] For example, the side of the second tip surface (S131b) and the first tip portion (131) may form a 65° angle, but the present invention is not limited thereto.

[0121] This may be to prevent the surgical tool moving from the front part of the tip part (130) through the placement part (150) from colliding with the camera part or the light-emitting part as it moves up and down.

[0122] In addition, due to the first tip surface (S131a), the surgical tool in the placement portion (150) can move more effectively in the forward and backward directions.

[0124] The second tip portion (132) may be cylindrical in shape.

[0125] However, not limited thereto, the shape of the second tip portion (132) can be varied in various ways that are obvious to a person skilled in the art.

[0126] A plurality of holes penetrating in the longitudinal direction may be formed in the second tip portion (132).

[0128] The first placement hole (h131) may have a first-1 placement hole (h131a) formed in the first tip portion (131) and a first-2 placement hole (h131b) formed in the second tip portion (132) that is connected to the first-1 placement hole (h131a).

[0129] The width (diameter) of the 1-1 placement hole (h131a) may be smaller than the width (diameter) of the 1-2 placement hole (h131b).

[0130] As a result, the first-1 placement hole (h131a) and the first-2 placement hole (h131b) can form a step.

[0131] The above-mentioned placement part (150) is inserted into the first-second placement hole (h131b), so that the above-mentioned placement part (150) can come into contact with the ends of the first-first placement hole (h131a) and the first-second placement hole (h131b).

[0132] The first and second placement holes (h131b) can be formed at an angle from the tip portion (130) toward the handle portion (110) (from the front direction toward the rear direction).

[0133] This may be intended to cause the above-mentioned arrangement part (150) to be positioned at an angle.

[0134] For example, only the lower side of the first-second placement hole (h131b) may be formed to be inclined, and the upper side of the first-second placement hole (h131b) may be formed parallel to the inner side of the shaft portion.

[0135] This may be due to the shape of the above-mentioned arrangement part (150).

[0136] For example, the first placement hole (h131) may have a diameter that is more than twice the diameter of the second placement hole (h132).

[0138] The second placement hole (h132) may have a second-1 placement hole (h132a) in which a camera unit (140) is placed, and a second-2 placement hole (h132b) connected to the second-1 placement hole (h132a).

[0139] The second-1 placement hole (h132a) can be formed in the first tip portion (131).

[0140] For example, the width of the 2-1 placement hole (h132a) may be larger than the width of the 2-2 placement hole (h132b), but the present invention is not limited thereto.

[0141] For example, the 2-1 placement hole (h132a) may be a square hole, but the present invention is not limited thereto.

[0142] A glass or lens is placed at the front end of the 2-1 placement hole (h132a) to prevent foreign substances from contaminating the camera part (140) during surgery.

[0143] The second-1 placement hole (h132a) can be formed at an angle from the first tip portion (131) toward the second tip portion (132).

[0144] This may be so that the camera unit (140) can photograph the upper part of the tip unit (130) more efficiently.

[0145] The second-2 placement hole (h132b) may be formed on the first tip portion (131) and the second tip portion (132).

[0146] The 2-1 placement hole (h132a) and the 2-2 placement hole (h132b) can form a step.

[0147] For example, the 2-2 placement hole (h132b) may be cylindrical in shape, but the present invention is not limited thereto.

[0148] A camera wire can be placed in the 2-2 placement hole (h132b).

[0149] The second placement hole (h132) can be located below the first placement hole (h131).

[0151] The third placement hole (h133) may have a third-1 placement hole (h133a) in which a light-emitting part (160) is placed, and a third-2 placement hole (h133b) connected to the third-1 placement hole (h133a).

[0152] The 3-1 placement hole (h133a) can be formed in the first tip portion (131).

[0153] The width of the 3-1 placement hole (h133a) may be greater than the width of the 3-2 placement hole (h133b), but the present invention is not limited thereto.

[0154] For example, the 3-1 placement hole (h133a) may be a square hole, but the present invention is not limited thereto.

[0155] For example, the light-emitting part may be an LED element. However, it is not limited thereto, and the type of the light-emitting part can be varied in various ways that are obvious to a person skilled in the art.

[0156] A glass or lens is placed at the front end of the 3-1 placement hole (h133a) to prevent foreign substances from contaminating the light-emitting part during surgery.

[0157] The 3-1 placement hole (h133a) can be formed at an angle from the first tip portion (131) toward the second tip portion (132).

[0158] This may be so that the light-emitting part can more efficiently photograph the upper part of the tip part (130).

[0159] The third-2 placement hole (h133b) may be formed on the first tip portion (131) and the second tip portion (132).

[0160] The 3-1 placement hole (h133a) and the 3-2 placement hole (h133b) can form a step.

[0161] For example, the 3-2 placement hole (h133b) may be cylindrical in shape, but the present invention is not limited thereto.

[0162] A wire connecting the light-emitting part and the board part to each other can be placed in the 3-2 placement hole (h133b).

[0164] The fourth placement hole (h134) may include a fourth-1 placement hole (h134a) formed in the first tip portion (131) and a fourth-2 placement hole (h134b) formed in the second tip portion (132) which is connected to the fourth-1 placement hole (h134a).

[0165] The width (diameter) of the 4-1 placement hole (h134a) may be smaller than the width (diameter) of the 4-2 placement hole (h134b).

[0166] As a result, the above 4-1 placement hole (h134a) and the above 4-2 placement hole (h134b) can form a step.

[0167] A water pipe is placed in the 4-2 placement hole (h134b), and the water pipe can come into contact with the ends of the 4-1 placement hole (h134a) and the 4-2 placement hole (h134b).

[0168] The water pipe inserted into the 4-2 placement hole (h134b) can be connected to the water pipe placed within the water pipe mediating part (115).

[0169] Water discharged from the water pipe can be sprayed into the surgical site through the 4-1 batch hole (h134a).

[0170] For example, the 4-1 placement hole (h134a) may be cylindrical in shape, but the present invention is not limited thereto.

[0171] For example, the 4-2 placement hole (h134b) may be cylindrical in shape, but the present invention is not limited thereto.

[0173] The camera unit (140) may be an electronic camera.

[0174] The camera unit (140) can photograph the surgical site to generate a photographic image, and can transmit the generated photographic image to the computing device through the computer wire.

[0175] For example, the camera unit (140) may be an electronic camera equipped with a CMOS image sensor.

[0176] However, not limited thereto, the type of image sensor mounted on the camera unit (140) can be varied in various ways that are obvious to a person skilled in the art.

[0177] Although electronic cameras have slightly lower image quality than optical cameras, they offer a wider field of view, making them efficient for securing visibility during endoscopic surgery.

[0178] In addition, since the electronic camera is smaller than the optical camera, the size of the second placement hole (h132) (specifically, the second-1 placement hole (h132a)) can be formed to be smaller than that of the existing endoscope equipment.

[0179] As the diameter of the second placement hole (h132) decreases, the diameter of the first placement hole (h131) can be made larger, and the placement portion (150) can be arranged at an angle.

[0181] The arrangement portion (150) may have a shape in which a hollow is formed on the inner side in the longitudinal direction.

[0182] For example, the arrangement portion (150) may be cylindrical in shape, but the present invention is not limited thereto.

[0183] One side of the arrangement portion (150) may be parallel to the shaft portion (120), and the other side may be formed at an angle from the shaft portion (120).

[0184] Here, one side of the above-mentioned arrangement part (150) may refer to a side facing upward with respect to the center of the above-mentioned arrangement part (150). Additionally, the other side of the above-mentioned arrangement part (150) may refer to a side facing downward with respect to the center of the above-mentioned arrangement part (150).

[0185] That is, the diameter of the front end of the placement section (150) can be formed to be smaller than the diameter of the rear end of the placement section (150).

[0186] That is, the cross-section of the above-mentioned arrangement portion (150) may be in a trapezoidal shape, but the present invention is not limited thereto.

[0187] The front end of the placement portion (150) can be inserted into the first-second placement hole (h131b) and come into contact with the rear end surface of the first tip portion (131).

[0188] Additionally, the rear end of the placement portion (150) can be inserted into and fixed in the second fixing hole (h112d) and the first-second fixing hole (h112c-2).

[0189] The placement portion (150) can be positioned at an angle from the tip portion (130) toward the handle portion (110).

[0190] A detailed explanation of the effect resulting from the arrangement of the placement section (150) at an angle will be provided later.

[0192] The board unit can transmit the captured image transmitted by the camera unit (140) to the computing device after receiving it from the camera unit (140).

[0194] Additionally, the board unit is electrically connected to the camera unit (140) and the light-emitting unit (160) to control the camera unit (140) and / or the light-emitting unit (160).

[0195] For example, the above board section may be configured to include a main board, a relay board, a front panel board, and a foot software board.

[0196] For example, the above board section has a fuse so that when an overcurrent occurs, the circuit of the above board section can be automatically cut off.

[0197] For example, the fuse specification may be T2A / 250V (B types without Y-capacitors), but the present invention is not limited thereto.

[0198] For example, the board portion may be configured to include a printed circuit board and a resistor, but the present invention is not limited thereto.

[0200] The computing device may be composed of an image input module that inputs a captured image received from the endoscope device, an image processing module that processes the acquired image, an image output module that outputs the image processed by the image processing module to a monitor, and a foot switch module that transmits a control signal to a light-emitting unit to turn the light-emitting unit on or off.

[0201] Here, the image processing module can perform functions such as Auto White Balance (AWB), Enhance (sharpness), Gain (external light acquisition), Freeze (image freeze), Zoom (image magnification), and LED (light intensity control).

[0202] The computing device mentioned in the present invention may refer to a device capable of processing information processing operations.

[0203] For example, computing devices may include desktop computers, laptops, smartphones, PDAs (Personal Digital Assistants), PMPs (Portable Multimedia Players), portable terminals, mobile devices and / or smart TVs, servers, etc.

[0205] The front end of the shaft portion (120) can be fitted onto the second tip portion (132) and come into contact with the rear end of the first tip portion (131).

[0206] For example, the front end of the shaft portion (120) can be detachably coupled to the second tip portion (132).

[0207] Additionally, the rear end of the shaft portion (120) can be inserted into the second fixing hole (h112d) and the first-second fixing hole (h112c-2).

[0208] Additionally, the front portion of the above-mentioned placement portion (150) can be inserted into the first-second placement hole (h131b).

[0209] The rear end of the shaft portion and the rear end of the placement portion can be connected to the surface of the first-1 fixing hole (h112c-1) to form a uniform surface without a step.

[0210] The camera unit (140) is positioned in the second-1 placement hole (h132a), and the light-emitting unit (160) can be positioned in the third-1 placement hole (h133a).

[0212] Below, the operation and effects of the endoscopic device will be described in detail.

[0214] FIG. 6 is a drawing for explaining the field of view of an endoscope device according to one embodiment of the present invention.

[0216] FIG. 6(a) is an endoscope image taken with an optical camera, and FIG. 6(b) may be an endoscope image taken with an electronic camera.

[0217] It can be confirmed that the field of view of the endoscope image captured by an electronic camera is larger than that of the endoscope image captured by an optical camera.

[0219] FIG. 7 is a drawing for explaining the operation of an endoscope device according to one embodiment of the present invention.

[0221] Referring to FIG. 7, as the lower side of the arrangement part (150) is inclined, the lower side of the arrangement part (150) and the lower side of the shaft part can form a predetermined angle (T10).

[0222] For example, a predetermined angle (T10) may be 14°, but the present invention is not limited thereto.

[0223] As the placement portion (150) is positioned at an angle, the surgical tool reaching the human body through the placement portion (150) can be moved further in the forward and backward directions.

[0224] By deciding that the camera unit (140) is an electronic camera, the field of view being captured is widened, and it may be necessary to have a wider range of motion for the surgical tool.

[0225] To achieve this, by increasing the diameter of the first placement hole (h131) and positioning the placement part (150) at an angle, a wider range of movement (G11) can be secured than when the placement part (150) is positioned without angle.

[0226] As a result, the doctor can conveniently perform surgery over a wider radius.

[0228] In addition, the endoscopic device of the present invention is a device that effectively lightens the endoscopic device by reducing the weight by 80% and the length by more than 40%. As a result, the surgical efficiency of medical personnel can be dramatically improved.

[0229] In addition, the above-mentioned endoscope device can provide an environment that allows medical personnel to perform surgery more easily by positioning elements that interfere with surgery (wire connecting parts, water pipe connecting parts) at the rear.

[0231] In order to more clearly express the technical concept of the present invention, the attached drawings briefly depict or omit configurations that are unrelated to or have little relevance to the technical concept of the present invention.

[0233] Although the structure and features of the present invention have been described above based on embodiments according to the present invention, the present invention is not limited thereto, and it is obvious to those skilled in the art that various changes or modifications can be made within the spirit and scope of the present invention; therefore, it is noted that such changes or modifications fall within the scope of the appended claims.
