Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a single-port thoracoscopic simulation operation device. Background Art

[0002] Single-port thoracoscopic surgery is a surgery that uses an incision smaller than 2.5 cm to perform various intrathoracic surgeries on the chest, such as lung wedge resection, lobectomy, segmentectomy, etc. Compared with traditional thoracoscopic surgery that requires 3-4 incisions, single-port thoracoscopic surgery only requires one incision, which greatly reduces surgical trauma and postoperative scars. Due to the reduction in the number of incisions, the sensory nerve damage of the chest wall is also reduced accordingly, and the postoperative pain is relatively mild. Pain relief helps patients to move, cough and expectorate early, thereby promoting postoperative recovery and shortening hospitalization time.

[0003] The existing invention patent with publication number CN116259204A in my country discloses a single-port thoracoscopic simulation operation device, but the patent has the following defects:

[0004] First, during actual thoracic surgery, the patient's body position will change according to the actual location of the lung lesion. The above patent can only simulate the patient's lying position, but cannot simulate the patient's side-lying position, which results in an incomplete simulation operation process and makes it impossible for the operator to conduct effective simulation training.

[0005] Second, when actually performing thoracic surgery, there will be a large amount of body fluid in the thoracic cavity, but the above patent does not simulate the body fluid, so when performing simulation training, the operation will be different from the actual surgery, which will reduce the realism of the simulation training;

[0006] Third, during simulation training, the lung model needs to be operated, so after multiple rounds of simulation training, the lung model needs to be replaced. The above patent is relatively cumbersome when replacing the lung model. It is necessary to open the chest model and then take out the rib model before replacing the lung model. Moreover, when there is simulated body fluid in the chest model, once the chest model is opened, the simulated body fluid will spill, eventually resulting in a waste of the simulated body fluid.

[0007] Therefore, it is necessary to provide a single-port thoracoscopic simulation operation device to solve the above problems. Summary of the invention

[0008] Based on this, it is necessary to provide a single-port thoracoscopic simulation operation device to address the existing technical problems.

[0009] In order to solve the problems of the prior art, the technical solution adopted by the present invention is: a single-port thoracoscopic simulation operation device, including a fixing seat, a rotating frame is provided on the fixing seat, a driving member for driving the rotating frame to rotate is provided on one side of the rotating frame, a quick-release connecting piece and a simulation box are provided on the rotating frame, the simulation box is in the shape of a rounded rectangle, the simulation box is fixedly connected to the rotating frame through the quick-release connecting piece, and when the simulation box is fixed on the rotating frame, the rounded ends of the simulation box are respectively facing the two sides of the rotating frame, a rib model, a lung model, a rib fixing piece and a lung fixing piece are provided in the simulation box, the rib model is fixedly connected to the simulation box through the rib fixing piece, and the lung model is fixedly connected to the rib through the lung fixing piece.

The No. 1 insertion strip is horizontally fixed to the outer wall of the support rod, and the No. 1 socket is horizontally fixed to the rib model. The cross-sections of the No. 1 insertion strip and the No. 1 socket are both T-shaped. The No. 1 insertion strip can be inserted into the No. 1 socket, and the rib model is fixed above the support rod through the cooperation of the No. 1 socket and the No. 1 insertion strip.

[0011] Furthermore, there are two lung models, and the lung fixing device includes two groups of arc-shaped pressure plates, which correspond to the two lung models respectively. Each arc-shaped pressure plate is provided with an elastic bent rod connecting the arc-shaped pressure plate with the support rod, and each elastic bent rod is used to press the arc-shaped pressure plate toward the corresponding lung model. The side of each arc-shaped pressure plate facing the corresponding lung model is a convex surface, and each convex surface fits the heart pressure mark of the corresponding lung model.

[0012] Furthermore, the rotating frame is a rectangular frame, and a horizontal rotating shaft is fixed at both ends of the rotating frame. Two vertical supporting frames are fixed on the fixed seat, and the two supporting frames are spaced apart in the horizontal direction. The rotating shafts at both ends of the rotating frame are respectively rotatably connected to the upper ends of the two supporting frames. A vertical drainage channel is formed in the rotating frame, and both ends of the drainage channel penetrate the upper and lower layers of the rotating frame. When the simulation box is fixed on the rotating frame, the drainage channel is located directly below the water outlet, and the diameter of the drainage channel is larger than the diameter of the water outlet.

[0014] Furthermore, two symmetrical strip support frames are formed in the rotating frame, each strip support frame is horizontal, and the drainage channel is located between the two strip support frames. Each top bar is arranged directly above the corresponding strip support frame, and each top bar is parallel to the corresponding strip support frame. The bottom of each top bar is formed with a number of vertical pins distributed equidistantly along the length direction of the top bar, and each vertical pin passes downward through the top of the corresponding strip support frame. Each vertical pin is sleeved with a vertical spring, and the two ends of the spring respectively conflict with the bottom of the top bar and the top of the strip support frame.

Two symmetrical No. 3 sockets are fixedly provided on the bottom of the rotating frame, and a counterweight bar is inserted in each No. 3 socket.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First, when it is necessary to simulate the patient's side-lying position, the driving member drives the rotating frame to rotate, so that the rotating frame will drive the entire simulation box to rotate, and finally one of the rounded ends of the simulation box will face upward. The rotating frame ensures that the simulation box can simulate the patient's side-lying position, making the simulation training process more complete and improving the training efficiency of the simulation operation;

[0019] Secondly, a water inlet is provided on the simulation box of the device, and simulated body fluid is injected into the simulation box through the water inlet, thereby improving the realism of the simulation training;

[0020] Thirdly, the lung model of the device is pressed on the rib model by an arc-shaped pressing plate, so that the fixation of the lung model is more realistic, and when disassembling the lung model, it is only necessary to open the simulation box and directly operate the lung model without removing the rib model, thereby improving the efficiency of disassembling the lung model;

[0021] Fourthly, before replacing the lung model, the simulated body fluid in the simulation box needs to be discharged first. The specific process of discharging the simulated body fluid is as follows: a water outlet is provided on the simulation box. The slide plate is pressed down and pulled out at the same time to separate the sealing plug from the water outlet. After that, the simulated body fluid will be discharged to the outside of the simulation box through the water outlet. Finally, the simulated body fluid in the simulation box is discharged before replacing the lung model, so as to prevent the simulated body fluid from spilling and causing waste when the simulation box is opened.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] refer to Figures 1 to 12 The single-port thoracoscopic simulation operation device shown comprises a fixing seat 1, a rotating frame 2 is arranged on the fixing seat 1, a driving member for driving the rotating frame 2 to rotate is arranged on one side of the rotating frame 2, a quick-release connector and a simulation box 3 are arranged on the rotating frame 2, the simulation box 3 is a rounded rectangular shape, the simulation box 3 is fixedly connected to the rotating frame 2 through the quick-release connector, and when the simulation box 3 is fixed on the rotating frame 2, the rounded ends of the simulation box 3 are respectively facing the two sides of the rotating frame 2, the simulation box 3 is provided with a rib model 4, a lung model 5, a rib fixing member and a lung fixing member, the rib model 4 is fixedly connected to the simulation box 3 through the rib fixing member, the lung model 5 is fixedly connected to the rib model 4 through the lung fixing member, the top and both ends of the simulation box 3 There are several simulated incisions 6 on the rounded corners, each simulated incision 6 is provided with a No. 1 rubber plug 7, a water inlet 8 is also provided on the top of the simulation box 3, and a No. 2 rubber plug 9 is provided on the water inlet 8, and a water outlet 10 is provided at the bottom of the simulation box 3, and a quick-install sealing mechanism is provided between the water outlet 10 and the rotating frame 2, and the quick-install sealing mechanism includes a slide plate 11, a sealing plug 12 and an elastic upper top piece, the slide plate 11 is slidably connected to the rotating frame 2 in the horizontal direction, the sealing plug 12 is fixed on the top of the slide plate 11, and the elastic upper top piece includes two groups of top strips 13 symmetrically arranged on both sides of the slide plate 11, each top strip 13 is located below the slide plate 11, and each top strip 13 is elastically connected to the rotating frame 2.

[0037] When installing the rib model 4 and the lung model 5 in the simulation box 3, the rib model 4 is first fixed in the simulation box 3 by the rib fixing piece, and then the lung model 5 is fixed in the rib model 4 by the lung fixing piece. The simulation box 3 is used to simulate the chest cavity of the human body. After the rib model 4 and the lung model 5 are installed, the simulation box 3 is fixed on the rotating frame 2 by the quick-release connector. After the simulation box 3 is fixed on the rotating frame 2, the simulation box 3 is fixed to the rotating frame 2. Figure 1 and Figure 4 As shown, the two rounded ends of the simulation box 3 are respectively facing the two sides of the rotating frame 2. At this time, the simulation box 3 is in a state of simulating a human body lying flat. Before performing the thoracoscopic simulation operation, an appropriate amount of simulated body fluid (not shown in the figure) is first injected into the simulation box 3 through the water inlet 8. In order to prevent the simulated body fluid from flowing out of the water outlet 10, the water outlet 10 needs to be blocked before injecting the simulated body fluid. The specific process of blocking the water outlet 10 is as follows: the two top bars 13 are pressed down by the handheld slide 11. After the slide 11 presses the two top bars 13 down, the slide 11 is pushed toward the water outlet 10. When the sealing plug 12 provided on the slide 11 is After being located directly below the water outlet 10, the slide plate 11 is released. At this time, the slide plate 11 will be pushed up by the two top strips 13, and finally the sealing plug 12 will be inserted upward into the water outlet 10, and the water outlet 10 will be blocked by the sealing plug 12. When the water outlet 10 is blocked, the simulated body fluid is injected into the simulation box 3 through the water inlet 8, and then the water inlet 8 is blocked by the No. 2 rubber plug 9. When performing the thoracoscopic simulation operation, the operator selects a simulated incision 6 and pulls out the No. 1 rubber plug 7. Thereafter, the thoracoscope and the minimally invasive scalpel are inserted into the simulation box 3 through the current simulated incision 6. The thoracoscope is used to observe the inside of the simulation box 3. In the case of a thoracoscope, the image observed by the thoracoscope is displayed through an external display (not shown in the figure), and the operator controls the minimally invasive scalpel to cut the lung model 5 by observing the image on the external display. When the thoracic surgery is actually performed, the patient's surgical position will change according to the actual location of the lung lesion. When it is necessary to simulate the patient's side-lying position, the rotating frame 2 is driven to rotate by the driving member, so that the rotating frame 2 will drive the entire simulation box 3 to rotate, and finally one of the rounded ends of the simulation box 3 is facing upward. After the lung model 5 has been cut for multiple rounds, the lung model 5 needs to be replaced. At this time, The simulated body fluid in the simulation box 3 must be discharged first. The specific process of discharging the simulated body fluid is as follows: press down the slide plate 11 and pull it outward at the same time, so that the sealing plug 12 is separated from the water outlet 10, and finally the simulated body fluid will be discharged to the outside of the simulation box 3 through the water outlet 10. When the simulated body fluid is discharged, a water collecting tank (not shown in the figure) can be used to collect the discharged simulated body fluid. After the lung model 5 is replaced, the simulated body fluid needs to be re-injected into the simulation box 3. At this time, the simulated body fluid collected in the water collecting tank can be poured back into the simulation box 3 through the water inlet 8, so as to realize the recycling of the simulated body fluid.

[0038] In order to show the specific structure of the rib fastener, the following features are set:

[0039] One end of the simulation box 3 is an open structure, and a horizontal support rod 14 is formed in the simulation box 3. A sealing cover 15 is provided on the opening structure of the simulation box 3, and the sealing cover 15 covers the opening of the simulation box 3, and the sealing cover 15 is connected to the support rod 14 by a fixing bolt 16. The rib fixing part includes a No. 1 plug 17 and a No. 1 socket 18. The No. 1 plug 17 is horizontally fixed to the outer wall of the support rod 14, and the No. 1 socket 18 is horizontally fixed to the rib model 4. The cross-sections of the No. 1 plug 17 and the No. 1 socket 18 are both T-shaped. The No. 1 plug 17 can be inserted in the No. 1 socket 18, and the rib model 4 is fixed above the support rod 14 through the cooperation of the No. 1 socket 18 and the No. 1 plug 17.

[0040] When installing the rib model 4, align the No. 1 plug 17 and the No. 1 socket 18, and insert the No. 1 plug 17 into the No. 1 socket 18, so that the rib model 4 will be fixed on the top of the support rod 14. The cooperation of the No. 1 plug 17 and the No. 1 socket 18 makes the disassembly and assembly of the ribs more convenient. After the rib model 4 is installed, the lung model 5 is fixed in the rib model 4, and finally the sealing cover 15 is fixed on the opening of the simulation box 3. When installing the sealing cover 15, first cover the opening of the simulation box 3 with the sealing cover 15, and then fix the sealing cover 15 to the support rod 14 through the fixing bolts 16, wherein a circle of rubber ring (not shown in the figure) is provided between the sealing cover 15 and the simulation box 3, and the rubber ring is used to prevent the simulated body fluid from flowing out of the gap between the simulation box 3 and the sealing cover 15.

[0041] In order to show the specific structure of the lung fixation, the following features are set:

[0042] There are two lung models 5, and the lung fixing parts include two groups of arc-shaped pressure plates 19, which correspond to the two lung models 5 respectively. Each arc-shaped pressure plate 19 is provided with an elastic bent rod 20 connecting the arc-shaped pressure plate 19 with the support rod 14, and each elastic bent rod 20 is used to press the arc-shaped pressure plate 19 toward the corresponding lung model 5. The side of each arc-shaped pressure plate 19 facing the corresponding lung model 5 is a convex surface 21, and each convex surface 21 fits the heart pressure mark of the corresponding lung model 5.

[0043] After the rib model 4 is installed, the lung model 5 is inserted into the rib model 4. During this process, the heart pressure mark of the lung model 5 is directed toward the convex surface 21 on the arc-shaped pressing plate 19. Then the lung model 5 is pushed into the cavity between the arc-shaped pressing plate 19 and the rib model 4. Finally, the lung model 5 is pressed onto the rib model 4 through the arc-shaped pressing plate 19. The arc-shaped pressing plate 19 makes it more convenient to disassemble and assemble the lung model 5.

[0044] In order to show the specific structure of the rotating frame 2, the following features are set:

[0045] The rotating frame 2 is a rectangular frame, and a horizontal rotating shaft 22 is fixedly provided at both ends of the rotating frame 2. Two vertical supporting frames 23 are fixedly provided on the fixing seat 1, and the two supporting frames 23 are spaced apart in the horizontal direction. The rotating shafts 22 at both ends of the rotating frame 2 are rotatably connected to the upper ends of the two supporting frames 23 respectively. A vertical drainage channel 24 is formed in the rotating frame 2, and both ends of the drainage channel 24 penetrate the upper and lower layers of the rotating frame 2. When the simulation box 3 is fixed on the rotating frame 2, the drainage channel 24 is located directly below the water outlet 10, and the diameter of the drainage channel 24 is larger than the diameter of the water outlet 10.

[0046] The rotating frame 2 is hollow to reduce its weight. The rotating shaft 22 is used for the rotating frame 2 to rotate. When the sealing plug 12 is separated from the water outlet 10, the simulated body fluid in the simulation box 3 will flow downward into the drainage channel 24 through the water outlet 10, and finally the simulated body fluid will be discharged along the drainage channel 24.

[0047] In order to show the specific structure of the quick-release connector, the following features are set:

[0048] The quick-release connector includes two elastic U-shaped strips 25 and two No. 2 sockets 26. The two elastic U-shaped strips 25 are symmetrically fixed on the top of the rotating frame 2, and each elastic U-shaped strip 25 is horizontal. The two No. 2 sockets 26 are symmetrically fixed on the bottom of the simulation box 3. The two No. 2 sockets 26 correspond to the two elastic U-shaped strips 25, and each elastic U-shaped strip 25 can be inserted into the corresponding No. 2 socket 26.

[0049] When installing the simulation box 3, the simulation box 3 is pushed toward the rotating frame 2. During this process, each elastic U-shaped strip 25 arranged on the rotating frame 2 is inserted into the corresponding No. 2 socket 26. Figure 3 As shown, each elastic U-shaped strip 25 presses the corresponding No. 2 socket 26 downwards by elasticity, thereby fixing the simulation box 3.

[0050] In order to show how the top bar 13 pushes the skateboard 11 up, the following features are set:

[0051] Two symmetrical strip support frames 27 are formed in the rotating frame 2, each of which is horizontal. The drainage channel 24 is located between the two strip support frames 27, and each top bar 13 is arranged directly above the corresponding strip support frame 27. Each top bar 13 is parallel to the corresponding strip support frame 27. The bottom of each top bar 13 is formed with a plurality of vertical pins 28 distributed equidistantly along the length direction of the top bar 13, and each vertical pin 28 passes downward through the top of the corresponding strip support frame 27. Each vertical pin 28 is sleeved with a vertical spring 29, and the two ends of the spring 29 are respectively in conflict with the bottom of the top bar 13 and the top of the strip support frame 27. Two strip through grooves 30 are provided on the top of the rotating frame 2 for the two top bars 13 to pass upward, and two symmetrical limiting vertical plates 31 (such as Fig. 9 As shown in the figure, the slide plate 11 slides horizontally between the two limiting upright plates 31, and the top of each limiting upright plate 31 is formed with a limiting convex strip 32 extending horizontally toward the slide plate 11.

[0052] When the water outlet 10 is blocked, the slide plate 11 is horizontally inserted between the two limit vertical plates 31, and at the same time, the two top strips 13 are pressed down by the slide plate 11. During this process, each top strip 13 will drive a number of vertical pins 28 to descend, and each vertical pin 28 will compress the spring 29. When the slide plate 11 slides to the point where the sealing plug 12 is directly below the water outlet 10, the slide plate 11 is released. At this time, each top strip 13 will rise due to the elastic force of a number of groups of springs 29, so that the slide plate 11 is pushed up by the two top strips 13, and finally the sealing plug 12 is inserted upward into the water outlet 10. When the water outlet 10 needs to be opened, the slide plate 11 is pressed down and the slide plate 11 is quickly pulled out, so that the sealing plug 12 is separated from the water outlet 10, and finally the water outlet 10 is opened. After the water outlet 10 is opened, the simulated body fluid in the simulation box 3 will flow downward from the water outlet 10 into the drainage channel 24.

[0053] In order to show the specific structure of the drive, the following features are set:

[0054] The driving member includes a worm wheel 33 and a worm 34 . The worm wheel 33 is coaxially fixedly connected to one of the rotating shafts 22 . The worm 34 is horizontally connected to one of the supporting frames 23 for rotation, and the worm 34 is meshed with the worm wheel 33 .

[0055] The simulation box 3 can be driven to rotate by electric drive and manual drive. When electric drive is adopted, a motor (not shown in the figure) needs to be installed on the fixed seat 1, and a transmission part needs to be installed between the motor and the worm 34, and finally the worm 34 is driven to rotate by the motor. When manual drive is adopted, a handle (not shown in the figure) needs to be installed on the worm 34, and the worm 34 is driven to rotate by manually shaking the handle. When the worm 34 rotates, the worm 34 will drive the worm wheel 33 to rotate, and finally drive the simulation box 3 to rotate. Since the worm wheel 33 cannot drive the worm 34 to rotate in the reverse direction, when the simulation box 3 rotates, the simulation box 3 will be in the current state and will not rotate.

[0056] When the simulation box 3 is driven to rotate by the rotating frame 2, the following features are set to make the simulation box 3 more stable:

[0057] The top of the rotating frame 2 is formed with a claw, which includes four groups of arc-shaped holding rods 35 distributed in a rectangular shape. Two symmetrical No. 3 sockets 36 are fixedly provided at the bottom of the rotating frame 2, and a counterweight bar 37 is inserted in each No. 3 socket 36.

[0058] During the process of pushing the simulation box 3 toward the rotating frame 2, each elastic U-shaped strip 25 will be inserted into the corresponding No. 2 socket 26, and at the same time, four sets of arc-shaped holding rods 35 will hold the simulation box 3 tightly, so as to make the simulation box 3 more stable on the rotating frame 2. During the simulation operation, simulated body fluid needs to be injected into the simulation box 3, and the weight of the simulation box 3 is heavy. In order to balance the weight on the upper and lower sides of the rotating frame 2, two counterweight bars 37 are installed at the bottom of the rotating frame 2 to ensure that the weight on both sides of the rotating frame 2 is equal, thereby ultimately improving the stability of the rotating frame 2 during rotation.

[0059] Working principle:

[0060] When installing the rib model 4 and the lung model 5 into the simulation box 3, the rib model 4 is first fixed in the simulation box 3 by the rib fixing piece, and then the lung model 5 is fixed in the rib model 4 by the lung fixing piece. The simulation box 3 is used to simulate the chest cavity of the human body. After the rib model 4 and the lung model 5 are installed, the simulation box 3 is fixed on the rotating frame 2 by the quick release connector. After the simulation box 3 is fixed on the rotating frame 2, Figure 1As shown, the two rounded ends of the simulation box 3 are respectively facing the two sides of the rotating frame 2. At this time, the simulation box 3 is in a state of simulating a human body lying flat. Before performing the thoracoscopic simulation operation, an appropriate amount of simulated body fluid (not shown in the figure) is first injected into the simulation box 3 through the water inlet 8. In order to prevent the simulated body fluid from flowing out of the water outlet 10, the water outlet 10 needs to be blocked before injecting the simulated body fluid. The specific process of blocking the water outlet 10 is as follows: the two top bars 13 are pressed down by the handheld slide 11. After the slide 11 presses the two top bars 13 down, the slide 11 is pushed toward the water outlet 10. When the sealing plug 12 provided on the slide 11 is in the position After being directly below the water outlet 10, the slide plate 11 is released. At this time, the slide plate 11 will be pushed up by the two top strips 13, and finally the sealing plug 12 will be inserted upward into the water outlet 10, and the water outlet 10 will be blocked by the sealing plug 12. When the water outlet 10 is blocked, the simulated body fluid is injected into the simulation box 3 through the water inlet 8, and then the water inlet 8 is blocked by the No. 2 rubber plug 9. When performing the thoracoscopic simulation operation, the operator selects a simulated incision 6 and pulls out the No. 1 rubber plug 7. Thereafter, the thoracoscope and the minimally invasive scalpel are inserted into the simulation box 3 through the current simulated incision 6. The thoracoscope is used to observe the inside of the simulation box 3. The image observed by the thoracoscope is displayed on an external display (not shown in the figure). The operator controls the minimally invasive scalpel to cut the lung model 5 by observing the image on the external display. When the thoracic surgery is actually performed, the patient's surgical position will change according to the actual location of the lung lesion. When it is necessary to simulate the patient's side-lying position, the rotating frame 2 is driven to rotate by the driving member, so that the rotating frame 2 will drive the entire simulation box 3 to rotate, and finally one of the rounded ends of the simulation box 3 is facing upward. After the lung model 5 has been cut for many rounds, the lung model 5 needs to be replaced. At this time, The simulated body fluid in the simulation box 3 must be discharged first. The specific process of discharging the simulated body fluid is as follows: press down the slide plate 11 and pull it outward at the same time, so that the sealing plug 12 is separated from the water outlet 10, and finally the simulated body fluid will be discharged to the outside of the simulation box 3 through the water outlet 10. When the simulated body fluid is discharged, a water collecting tank (not shown in the figure) can be used to collect the discharged simulated body fluid. After the lung model 5 is replaced, the simulated body fluid needs to be re-injected into the simulation box 3. At this time, the simulated body fluid collected in the water collecting tank can be poured back into the simulation box 3 through the water inlet 8, so as to realize the recycling of the simulated body fluid.
