Additionally, the photographing module 200 may be inserted between the plurality of stationary wings 532, so that one side of the fixing plate 531 and the photographing module 200 may be combined.
The stationary wing 532 may be provided with a wing extension extending outward from the edges of both sides of the stationary wing 532, and a hinge hole formed in the shape of a hole may be formed at the horizontal and vertical centers of the wing extension. One support wing 542 may be located between one wing extension and another wing extension, and one hinge hole and the hinge fixing hole formed in the support wing 542 may be hingedly coupled to another hinge hole.
As a result, even if the angle θ between the support wings 540 changes, the coupling angle formed by the coupling of the support wing 542 and stationary wing 532 changes according to the angle θ between the support wings 540, thereby facilitating the coupling of the wing fixing part 530 and support wing part 540. Due to the wing fixing part 530 formed of a flexible material, when the angle θ between the fixed plate 531 and the stationary wing 532 changes due to an external force, the stationary wing 532 can be moved without being broken.
A plurality of stationary wings 532 may be formed to be spaced apart from the fixing plate 531, and 4 to 10 stationary wings 532 may be formed. Due to the space formed between one stationary wing 532 and the other stationary wing 532, the drainage material inside the chest cavity can be discharged between one stationary wing 532 and the other stationary wing 532.
The drainage substance is discharged into the space formed between one stationary wing 532 and the other stationary wing 532, so that the drainage substance can be drained without separating the photographing module 200 from the chest tube 100.
Due to this, a degree of drainage of the drainage substance may be monitored, and when drainage substance occurs in multiple locations, the pleural space may be monitored with the photographing module 200 and the chest tube 100 may be moved to easily remove the drainage substance. When drainage is completed and the chest tube 100 is removed from the pleural space, problem of damaging organs may be prevented by monitoring the inside of the body using the photographing module 200.
The angle θ between the fixing plate 531 and stationary wing 532 of the wing fixing part 530 may change by the movement of the moving body 550. When the rotation motor 520 rotates clockwise, the screw shaft 510 may rotate clockwise, and the rotation of the screw shaft 510 causes the moving body 550 to move in a direction from one side and the other side of the screw shaft 510. The support wing part 540 coupled to the outer surface of the moving body 550 may move in a direction from one side to the other side of the screw shaft 510 by the movement of the moving body 550, and as a result, the stationary wing 532 of the wing fixing part 530 coupled with the support wing part 540 may be moved toward the other side of the screw shaft 510, thereby increasing the angle θ between the fixing plate 531 and the stationary wing 532.
When the rotation motor 520 rotates counterclockwise, the screw shaft 510 may rotate counterclockwise, and the rotation of the screw shaft 510 causes the moving body 550 to move in a direction from the other side to one side of the screw shaft 510. The support wing part 540 coupled to the outer surface of the moving body 550 may move in a direction from the other side to one side of the screw shaft 510 by the movement of the moving body 550, and as a result, the stationary wing 532 of the wing fixing part 530 coupled with the support wing part 540 may be moved toward one side of the screw shaft 510, thereby reducing the angle θ between the fixing plate 531 and the stationary wing 532.
The stationary wing 532 may be provided with a contact body 533 extending from the upper edge of the stationary wing 532 toward the outer surface, and the contact body may be formed in a round shape. Due to the contact body, even when the angle θ between the fixing plate 531 and the stationary wing 532 changes, the contact area between the stationary wing 532 and the chest tube is formed to be the same, so that the chest tube and the chest tube fixation module 500 can be firmly fixed.
The support wing part 540 may include a support ring 541 that is formed in a shape surrounding the outer surface of the moving body 550, and a plurality of support wings 542 extending in a radial direction from the support ring 541.
The number of support wings 542 may be the same as the number of stationary wings 532, and one stationary wing 532 may be hingedly coupled with one support wing 542. The support wing 542 may be provided with a hinge fixing hole formed in the shape of a hole on the upper side of the support wing 542, and may be hinged with the hinge hole formed on the stationary wing 532.
The support wing part 540 may reciprocate linearly in the direction of one side and the other side of the screw shaft 510 bar by the movement of the moving body 550, so that the distance between the support wing part 540 and the wing fixing part 530 may be changed. When a distance between the support wing part 540 and the wing fixing part 530 increases, the angle θ between the fixing plate 531 and the stationary wing 532 may increase, and when a distance between the support wing part 540 and the wing fixing part 530 is shortened, the angle θ between the fixing plate 531 and the stationary wing 532 may decrease.
The diameter measurement sensor 560 may be coupled to the other side of the screw shaft 510 and, when the diameter measurement sensor 560 is inserted into the chest tube, it may measure the diameter inside the chest tube. According to the inner diameter of the chest tube measured by the diameter measurement sensor 560, the controller controls the rotation motor 520 to change the angle θ between the fixing plate 531 of the wing fixing part 530 and the stationary wing 532.
The chest tube fixation module 500 may be provided with a battery that supplies power to the rotation motor 520, and in another embodiment, the rotation motor 520 may be connected to an outlet by a wire to supply power.
The controller may control transmitting the in-vivo image photographed by the photographing module 200 to the outside using a wireless communication method, and change the angle θ between the fixing plate 531 of the wing fixing part 530 and the stationary wing 532 by controlling the rotation motor 520 according to the diameter of the chest tube measured by the diameter measurement sensor 560.
As shown in
The angle θ between the fixing plate 531 of the wing fixing part 530 and the stationary wing 532 may change by the movement of the moving body 550. When the rotation motor 520 rotates clockwise, the screw shaft 510 may rotate clockwise, and the rotation of the screw shaft 510 causes the moving body 550 to move in a direction from one side to the other side of the screw shaft 510. The support wing part 540 coupled to the outer surface of the moving body 550 may move in a direction from one side to the other side of the screw shaft 510 by the movement of the moving body 550, and as a result, the stationary wing 532 of the fixing wing part 530 coupled with the support wing part 540 may be moved toward the other side of the screw shaft 510, thereby increasing the angle θ between the fixed plate 531 and the stationary wing 532. Because of this, the chest tube fixation module 500 can be easily fixed inside the chest tube with a large diameter.
When the rotation motor 520 rotates counterclockwise, the screw shaft 510 may rotate counterclockwise, and the rotation of the screw shaft 510 causes the moving body 550 to move in a direction from the other side to one side of the screw shaft 510. The support wing part 540 coupled to the outer surface of the moving body 550 may move in a direction from the other side to one side of the screw shaft 510 by the movement of the moving body 550, and as a result, the stationary wing 532 of the wing fixing part 530 coupled with the support wing part 540 may be moved toward one side of the screw shaft 510, thereby reducing the angle θ between the fixing plate 531 and the stationary wing 532. Because of this, the chest tube fixation module 500 can be easily fixed inside the chest tube with a small diameter.
When the inner diameter (D) of the chest tube is large in the order of D1, D2, and D3, the angle (θ), which is an angle between the fixing plate 531 and the stationary wing 532, may be formed to be large in the order of θ1, θ2, θ3.
In another embodiment, as shown in
The camera cover 610 is formed in a shape that surrounds the photographing module 200. The material of the camera cover 610 may be formed of synthetic resin, rubber, and silicone. As a result, the camera cover 610 is stretched by an external force, so that the photographing module 200 may be easily inserted into the camera cover 610.
The pin part 620 includes a plurality of pins formed in an upward direction from the outer surface of the camera cover 610, and the plurality of pins may be in contact with the inner surface of the chest tube 100.
The camera fixation module 600 may be inserted from the other side of the chest tube 100 coupled with the drainage container to one side of the chest tube 100 entering the plural space, and the camera fixation module 600 may be formed to be inclined to form an acute angle with the flow direction of the fluid flowing from one side of the chest tube 100 to the other side of chest tube 100.
Because of this, even if the flow amount of fluid is large or negative pressure is applied to the chest tube 100, the plurality of pins forms an acute angle with the flow direction of the fluid and is fixed to the inside of the chest tube so that the camera fixation module 600 is not affected by the flow or negative pressure, and may be easily fixed to the inner surface of the chest tube 100.
In the plurality of pins, a pin angle α forming an acute angle may be formed between a tangent line parallel to the central axis of the camera cover 610 while contacting the plurality of pins on the outer peripheral surface of the camera cover 610 and the plurality of pins.
As shown in
When the inner diameter of the chest tube 100 is a first diameter D1, an external force may be applied to the plurality of pins to change the pin angle α and the first pin angle α1 may be formed. When the inner diameter of the chest tube 100 is a second diameter (D2), an external force may be applied to the plurality of pins to change the pin angle α and the second pin angle α2 may be formed. When the inner diameter of the chest tube 100 is a third diameter (D3), an external force may be applied to the plurality of pins to change the pin angle α and the third pin angle α3 may be formed.
When the inner diameter (D) of the chest tube 100 is large in the order of D1, D2, and D3, the pin angle α forming an acute angle between a tangent line parallel to the central axis of the camera cover 610 while contacting the plurality of pins on the outer peripheral surface of the camera cover 610 and the plurality of pins may be formed to be large in the order of α1, α2, and α3. In this case, the length of the pin may be longer than the radius of the inner surface of the chest tube 100.
Due to this, regardless of the diameter of the chest tube 100, the camera fixation module 600 may be inserted into the chest tube 100 by applying an external force to the plurality of pins according to the diameter of the chest tube 100. Regardless of the diameter of the chest tube 100, the camera fixation module 600 and the inner surface of the chest tube 100 may be fixed to easily change the chest tube 100 according to the amount of drainage.
The pin part 620 may be formed in plural number on the outer surface of the camera cover 610 parallel to the central axis of the camera cover 610, and fluid may flow along the space formed by the camera cover 610 and the plurality of pin parts 620.
That is, fluid may flow along one space formed by one pin part 620, the other pin part 620, the camera cover 610, and the chest tube 100, allowing smooth drainage. Four to six pin parts 620 may be formed, and four pin parts 620 may be formed in the disclosure, but the number is not limited thereto.
A (S1) zone formed by the first pin part 620 and the second pin part 620, (S2) zone formed by the second pin part 620 and the third pin part 620, and (S3) zone formed by the third pin part 620 and the fourth pin part, and (S4) zone formed by the fourth pin part 620 and the first pin part 620 may be formed.
Fluid may flow through the space formed in the (S1, 2, 3, 4) zones. Accordingly, through the space formed in the (S1, 2, 3, 4) zones in which the photographing module 200 is inserted into the chest tube 100 using the camera fixation module 600, the fluid is drained, and the drainage may be performed without separating the photographing module 200 from the chest tube 100.
In addition, the pin part 620 may be provided in plural numbers, and fluid flows along a space formed by one pin, another pin, the camera cover 610, and the chest tube 100 to facilitate smooth drainage. 3 to 5 pins may be formed in one pin part 620, and in the disclosure, 3 pins may be formed, but the number is not limited thereto.
A (S5) zone formed by the first and second pins and (S6) zone formed by the second and third pins may be formed. The fluid flowing through the space formed in the (S1, 2, 3, 4) zones also flows the space formed in the (S5, 6) zones. Thus, the liquid formed in the pleural space is drained from one side of the chest tube 100 to the other side of the chest tube 100, and drainage may be easily performed without separating the photographing module 200 from the chest tube 100.
Due to this, drainage may be performed while fixing the photographing module 200 inside the chest tube 100 without removing it. When drainage substance occurs in multiple locations, the chest tube is monitored with the photographing module 200 and drainage is complete on a portion formed in the pleural space. Then, the inside of the pleural space is monitored through the photographing module 200, the chest tube 100 is moved, and drainage is performed on other portion formed in the pleural space, so that the drainage substance can be easily removed.
In addition, it is possible to monitor the amount and degree of drainage of objects located in the chest tube, so the completion point of drainage can be predicted. Also, when an object is removed from the pleural space, the internal of the body can be monitored using the photographing module 200 to prevent damage to organs, and the surgical site can be quickly sutured.
A method for inserting the chest tube 100 for thoracoscopy using the device for inserting the chest tube 100 for thoracoscopy may comprise the steps of (a) cutting an area to be operated and making a hole in a pleura, (b) combining the photographing module 200 and camera fixation module 600 and inserting the photographing module 200 and camera fixation module 600 in the pleura space, (c) photographing the inside of the subject's body by the photographing module 200 when the device for inserting the chest tube 100 is inserted into the subject's pleural space, and then transmitting the photographed in-vivo image to the mobile device 2000 using a wired or wireless communication method, (d) inserting the chest tube 100 based on the in-vivo image reproduced on the mobile device 2000, (e) separating the chest tube 100 and the handle module 300, and (g) connecting the chest tube 100 to the drainage container.
As shown in
After making an incision, Long Kelly and a finger can be used to widen the penetration window formed in the pleura to form a space in advance for the chest tube 100 to enter the pleural space.
After step (a), step (b), which is a step of combining the photographing module 200 and camera fixation module 600 and the photographing module 200 and camera fixation module 600 are inserted in the pleural space, may be performed. In step (b), as shown in
When inserting the camera fixation module 600 into the chest tube 100, an external force is applied to the plurality of pin parts 620 according to the diameter of the chest tube 100 to change the pin angle α to insert the camera fixation module 600 inside the chest tube 100.
The camera fixation module 600 may be formed inclined to form an acute angle with the flow direction of the fluid flowing from one side of the chest tube 100 to the other side of the chest tube 100. Thus, even if the flow amount of fluid is large or negative pressure is applied to the chest tube 100, the plurality of pins form an acute angle with the flow direction of the fluid and are fixed to the inside of the chest tube so that the camera fixation module 600 is not swept away by the flow and negative pressure and may be easily fixed to the inner surface of the chest tube 100, thereby preventing the chest tube fixation module 500 from being sucked into the drainage container by the flow.
After step (b) is performed, step (c) in which when the device for inserting the chest tube 100 is inserted into the subject's pleural space, the photographing module 200 photographs the inside of the subject's body, and then transfers the photographed in-vivo image to the mobile device 2000 using a wired or wireless communication method may be performed.
After step (c) is performed, step (d), which is a step of inserting the chest tube 100 based on the in-vivo image reproduced on the mobile device 2000, may be performed. In step (d), the in-vivo image information data transmitted from the photographing module 200 using the mobile device through a wired or wireless communication method may be reproduced on the display of the mobile device 2000 in real time.
After step (d) is performed, step (e), which is a step of inserting the chest tube 100 based on the in-vivo image reproduced on the mobile device 2000, may be performed. In step (e), the chest tube 100 is inserted based on the in-vivo image reproduced on the mobile device 2000 to insert the chest tube 100 into the appropriate depth of the chest tube, thereby preventing problems of damaging organs.
After step (e) is performed, step (e), which is a step of connecting the chest tube 100 to the drainage container, may be performed. In step (e), the other side of the chest tube 100 from which the photographing module 200 is removed is connected to the drainage container that stores the drainage substance located in the subject's pleural space, and the substance located inside the pleural space is transferred and drained from one side to the other side of the chest tube 100.
In addition, a degree of drainage of the drainage substance may be monitored by draining the drainage substance without separating the photographing module 200 from the chest tube 100. When the drainage substance occurs in multiple locations, the chest tube is monitored with the photographing module 200. The drainage substance may be easily removed by moving the chest tube 100, and when drainage is completed and the chest tube 100 is removed from the pleural space, it is possible to prevent organ damage by monitoring the inside of the body through the photographing module 200.
With the chest tube 100 inserted into the chest tube by the operator's breathing, the drainage substance may move from one side to the other side of the chest tube 100 and enter the inside of the drainage container. The drainage container may be formed of two bottles or three bottles, and water may be inserted into the drainage container to adjust the drainage time. Additionally, the drainage container may be connected to a vacuum pump, and when drainage is not smooth, negative pressure may be used to move the drainage substance located inside the pleural space.
