[0002] A thoracoscope is a medical device used to perform surgery inside a patient's chest cavity using a mirror and other tiny tools. Through the thoracoscope, doctors can observe and manipulate the patient's internal chest structure to provide more accurate diagnosis and treatment. Thoracoscopic surgery reduces the risk of large incisions in traditional open surgery and helps avoid surgery-related complications.

[0003] In the current related technology, a thoracoscope is usually inserted into the patient's chest cavity through a tube to monitor the inside of the patient's chest cavity, and then the surgery is performed.

[0011] Furthermore, an adjustment assembly is provided on the side wall of the extended end of the square rod away from the movable plate, and the adjustment assembly includes a rotating rod, a limiting groove, and a lifting ring. The rotating rod is rotatably connected to the end of the square rod away from the movable plate. The protective shell is cylindrical as a whole, and both ends of the side walls are ring-shaped, with a center connecting column and four side wall connecting columns in the middle. Four limiting grooves are respectively opened on the outer wall of the protective shell corresponding to the position of the rotating rod, and the side wall at the middle position of the rotating rod is slidably connected to the inner wall of the limiting groove.

The arcs of the 4 special-shaped frames are connected to each other to form a circular shape with gaps between them. The side of the cleaning strip close to the working plate is contacted and arranged on the side of the main thoracoscope away from the working plate.

[0014] Furthermore, the mirror surface of the main thoracoscope is located on the annular surface away from the working plate, and the mirror surface on the secondary thoracoscope is on the side away from the main thoracoscope.

[0015] A method for using an angle-adjustable thoracoscope, for realizing the angle-adjustable thoracoscope as described above, comprises the following steps:

[0016] Step 1: Perform monitoring, insert the cannula into the patient's chest cavity, start the micro-electric telescopic rod, the micro-electric telescopic rod drives the working plate to move, and the working plate drives the main thoracoscope to move;

[0017] The working plate drives the fixed tube to move, and the fixed tube drives the piston plate to move inside the fixed shell, so that the airflow inside the fixed shell enters into the fixed tube through the air hole setting, and the airflow enters into the bent tube through the fixed tube, and the airflow enters into the connecting shell through the bent tube, so that the moving plate inside the connecting shell slides, and the moving plate drives the square rod to move, and the square rod drives the connecting rod to move, and the connecting rod will contact with the inner wall of the arc hole during the movement, because the connecting rod is a linear motion, and is affected by the arc setting of the arc hole, the movement of the connecting rod will cause the rotating ring to rotate around the outer wall of the protective shell, and the rotating ring drives the concave frame to rotate synchronously, and the concave frame drives the secondary thoracoscope to rotate synchronously;

[0018] Step 2: Angle adjustment. During the movement of the square bar, the square bar drives the rotating bar to move. The rotating bar drives the lifting ring to slide along the outer wall of the main thoracoscope due to the position limit of the main thoracoscope. The lifting ring drives the vertical bar to move. The vertical bar drives the extrusion plate to move. During the movement of the extrusion plate, the side wall of the part of the square bar protruding from the clamping hole at one end of the square bar close to the main thoracoscope comes into contact with the square bar, so that the square bar is pushed by the extrusion plate. The square bar drives the secondary thoracoscope to rotate in a small circle along the concave frame.

[0019] Step 3: Pneumatic cleaning. When the moving plate moves to the circular tube position of the connecting shell, the airflow will enter the inside of the circular tube, and then enter the inside of the arc-shaped bucket through the circular tube. The setting of the arc-shaped bucket can diffuse the range of the airflow jet. During the process of the airflow jetting outward, the secretions inside the patient's chest cavity can be jetted.

[0020] When the rotating ring rotates, the rotating ring drives the round rod to rotate, the round rod drives the special-shaped frame to rotate, and the special-shaped frame drives the cleaning strip to rotate. During the rotation of the cleaning strip, the mucus adhered to the mirror surface of the main thoracoscope can be cleaned;

[0021] Step 4: Auxiliary monitoring. During the process of the moving plate moving to the circular tube position of the connection shell, the spring accumulates elastic potential energy. When the airflow inside the fixed shell is completely discharged, the spring releases the elastic potential energy, and the spring drives the moving plate to perform a reset movement, thereby causing the sub-thoracoscope to rotate in the opposite direction. When the airflow inside the fixed shell is completely discharged, the extrusion plate no longer squeezes the square bar, and is elastically deformed by the arc spring. The arc spring drives the square bar to move, and the square bar drives the sub-thoracoscope to perform a reset movement; the sub-thoracoscope rotates around the inner wall of the concave frame and performs a small reciprocating rotation.

[0022] The beneficial effects of the present invention are:

[0023] During the rotation of the secondary thoracoscope, the patient's chest cavity can be monitored in a circular rotation, thereby improving the comprehensiveness of the monitoring; the secondary thoracoscope can further monitor the patient's chest cavity by adjusting the angle, thereby improving the accuracy of the monitoring; due to the setting of the arc-shaped bucket, the range of the airflow jet can be diffused, and during the outward ejection of the airflow, the secretions inside the patient's chest cavity can be sprayed to prevent the secretions from adhering to the mirror surface of the secondary thoracoscope, and the space of the patient's chest cavity can be slightly expanded to prevent the secondary thoracoscope from touching the flesh and blood tissue inside the chest cavity during the rotation monitoring process, thereby improving the protection effect on the patient during the monitoring process; during the rotation of the cleaning strip, the mirror mucus of the main thoracoscope can be cleaned by setting the gaps between multiple special-shaped frames. When the mucus is scraped off on one side of the cleaning strip, the mucus will slide down along the gap to prevent the mucus from adhering to the mirror surface of the main thoracoscope, thereby improving the monitoring effect of the main thoracoscope from the side.

[0038] like Figure 5 As shown, four concave frames 467 are fixedly connected to the annular surface of the rotating ring 465 on one side away from the working plate 41, and the secondary thoracoscope 468 is rotatably connected to the two parallel sides of the inner walls of the concave frames 467. The secondary thoracoscope 468 rotates along its own central axis parallel to the working plate 41. The mirror surface on the secondary thoracoscope 468 is on the side away from the main thoracoscope 42. One end of the arc spring 469 is fixedly connected to the inner wall of the bottom of the concave frame 467, and the other end of the arc spring 469 is fixedly connected to the side wall of the square bar 4610. One end of the square bar 4610 is fixedly connected to the side of the outer wall of the secondary thoracoscope 468 close to the main thoracoscope 42.

[0039] like Figure 1 , 4 As shown in , 6 and 7, an adjusting assembly 47 is provided on the side wall of the extended end of the square rod 462 away from the movable plate 461, and the adjusting assembly 47 includes a rotating rod 471, a limiting groove 472 and a lifting ring 473. The rotating rod 471 is rotatably connected to the end of the square rod 462 away from the movable plate 461. The protective shell 43 is cylindrical as a whole, and both ends of the side wall are annular, with a central connecting column and four side wall connecting columns in the middle. Four limiting grooves 472 are respectively opened on the outer wall of the protective shell 43 corresponding to the position of the rotating rod 471, and the side wall at the middle position of the rotating rod 471 is slidably connected to the inner wall of the limiting groove 472. The end of the rotating rod 471 away from the square rod 462 is rotatably connected to the lifting ring 473, and there are 4 corresponding lifting rings 473.

[0040] like Figure 1 , 4As shown in , 7, the inner wall of the lifting ring 473 is slidably connected to the outer wall of the main thoracoscope 42, and the end of the lifting ring 473 away from the working plate 41 is fixedly connected to one end of the vertical rod 474, and the other end of the vertical rod 474 is fixedly connected to the extrusion plate 475. There is only one extrusion plate 475, and the extrusion plate 475 and the rotating ring 465 form an inner ring and an outer ring on the same horizontal plane. Four clamping holes 476 are respectively opened around the outer wall of the protective shell 43 near the four limit grooves 472, and the end of the square bar 4610 away from the secondary thoracoscope 468 is arranged inside the clamping hole 476. A cleaning assembly 48 is provided on the rotating ring 465. There are four cleaning assemblies 48, and the cleaning assembly 48 includes a round rod 481, a special-shaped frame 482, and a cleaning strip 483. One end of the round rod 481 is fixedly connected to the ring surface of the rotating ring away from the working plate 41, and the other end of the round rod 481 is fixedly connected to one end of the special-shaped frame 482. The other end of the special-shaped frame 482 is arc-shaped and fixedly connected to one end of the cleaning strip 483. The arcs of the four special-shaped frames 482 are connected to each other to form a circular ring shape and there are gaps between them. The side of the cleaning strip close to the working plate 41 is contacted and arranged on the side of the main thoracoscope away from the working plate 41.

[0041] A method for using an angle-adjustable thoracoscope, such as Figure 8 As shown, the following steps are included:

[0042] Step 1: Monitor, insert the cannula 1 into the patient's chest cavity, start the micro-electric telescopic rod 3, the micro-electric telescopic rod 3 drives the working plate 41 to move, the working plate 41 drives the main thoracoscope 42 to move, and the main thoracoscope 42 can monitor the inside of the chest cavity during the movement;

[0043] The working plate 41 drives the fixed pipe 452 to move, and the fixed pipe 452 drives the piston plate 451 to move inside the fixed shell 44, so that the airflow inside the fixed shell 44 enters the inside of the fixed pipe 452 through the setting of the air hole 453, and the airflow enters the inside of the bent pipe 455 through the fixed pipe 452, and the airflow enters the inside of the connecting shell 454 through the bent pipe 455, so that the moving plate 461 inside the connecting shell 454 slides, and the moving plate 461 drives the square rod 462 to move, and the square rod 462 drives the connecting rod 46 4 moves, and the connecting rod 464 contacts the inner wall of the arc hole 466 during the movement. Since the connecting rod 464 moves in a straight line, and is affected by the arc setting of the arc hole 466, the movement of the connecting rod 464 causes the rotating ring 465 to rotate around the outer wall of the protective shell 43, and the rotating ring 465 drives the concave frame 467 to rotate synchronously, and the concave frame 467 drives the sub-thoracoscope 468 to rotate synchronously. During the rotation of the sub-thoracoscope 468, the circumferential rotation of the patient's chest cavity can be monitored, thereby improving the comprehensiveness of the monitoring;

[0044] Step 2: Angle adjustment. When the square rod 462 moves, the square rod 462 drives the rotating rod 471 to move. The rotating rod 471 drives the lifting ring 473 to slide along the outer wall of the main thoracoscope 42 due to the position limitation of the main thoracoscope 42. The lifting ring 473 drives the vertical rod 474 to move. The vertical rod 474 drives the squeezing plate 475 to move. During the movement of the squeezing plate 475, the side wall of the square bar 4610 protruding from the clamping hole 476 at one end of the main thoracoscope 42 is contacted, so that the square bar 4610 is pushed by the squeezing plate 475. The square bar 4610 drives the secondary thoracoscope 468 to rotate in a small circle along the concave frame 467. Thus, the secondary thoracoscope 468 can adjust its angle, further monitor the inside of the patient's chest cavity, and improve the accuracy of monitoring.

[0045] Step 3: Pneumatic cleaning. When the movable plate 461 moves to the position of the circular tube 456 connected to the shell 454, the airflow will enter the interior of the circular tube 456, and then enter the interior of the arc-shaped bucket 457 through the circular tube 456. The arc-shaped bucket 457 is set to diffuse the range of the airflow jet. During the outward jetting process, the airflow can spray the secretions inside the patient's chest cavity to prevent the secretions from adhering to the mirror surface of the secondary thoracoscope 468, and can slightly expand the space of the patient's chest cavity to prevent the secondary thoracoscope 468 from touching the flesh and blood tissue inside the chest cavity during the rotation monitoring process, thereby improving the protection effect on the patient during the monitoring process.

[0046] When the rotating ring 465 rotates, the rotating ring 465 drives the round rod 481 to rotate, the round rod 481 drives the special-shaped frame 482 to rotate, and the special-shaped frame 482 drives the cleaning bar 483 to rotate. During the rotation of the cleaning bar 483, the mucus adhered to the mirror surface of the main thoracoscope 42 can be cleaned. Through the gap setting between the multiple special-shaped frames 482, when the mucus is scraped on one side of the cleaning bar 483, the mucus will slide down along the gap to prevent the mucus from adhering to the mirror surface of the main thoracoscope 42, thereby improving the monitoring effect of the main thoracoscope 42.

[0047] Step 4: Auxiliary monitoring. During the process of the moving plate 461 moving to the position of the circular tube 456 connecting the shell 454, the spring 463 accumulates elastic potential energy. When the airflow inside the fixed shell 44 is completely discharged, the spring 463 releases the elastic potential energy, and the spring 463 drives the moving plate 461 to perform a reset movement, so that the sub-thoracoscope 468 rotates in the opposite direction to further monitor the inside of the patient's chest cavity. When the airflow inside the fixed shell 44 is completely discharged, the squeezing plate 475 no longer squeezes the square bar 4610, and is elastically deformed by the arc spring 469. The arc spring 469 drives the square bar 4610 to move, and the square bar 4610 drives the sub-thoracoscope 468 to perform a reset movement. The sub-thoracoscope 468 rotates around the inner wall of the concave frame 467 and reciprocates in a small range of about 60 degrees. In this way, the monitored area is monitored again, further improving the accuracy of the sub-thoracoscope 468 in monitoring the inside of the patient's chest cavity.

[0048] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.

10. A method for using an angle-adjustable thoracoscope, characterized in that: A thoracoscope for realizing an adjustable angle as claimed in any one of claims 1 to 9, comprising the following steps: Step 1: Perform monitoring, insert the cannula into the patient's chest cavity, start the micro-electric telescopic rod, the micro-electric telescopic rod drives the working plate to move, and the working plate drives the main thoracoscope to move; The working plate drives the fixed tube to move, and the fixed tube drives the piston plate to move inside the fixed shell, so that the airflow inside the fixed shell enters into the fixed tube through the air hole setting, and the airflow enters into the bent tube through the fixed tube, and the airflow enters into the connecting shell through the bent tube, so that the moving plate inside the connecting shell slides, and the moving plate drives the square rod to move, and the square rod drives the connecting rod to move, and the connecting rod will contact with the inner wall of the arc hole during the movement, because the connecting rod is a linear motion, and is affected by the arc setting of the arc hole, the movement of the connecting rod will cause the rotating ring to rotate around the outer wall of the protective shell, and the rotating ring drives the concave frame to rotate synchronously, and the concave frame drives the secondary thoracoscope to rotate synchronously; Step 2: Angle adjustment. During the movement of the square bar, the square bar drives the rotating bar to move. The rotating bar drives the lifting ring to slide along the outer wall of the main thoracoscope due to the position limit of the main thoracoscope. The lifting ring drives the vertical bar to move. The vertical bar drives the extrusion plate to move. During the movement of the extrusion plate, the side wall of the part of the square bar protruding from the clamping hole at one end of the square bar close to the main thoracoscope comes into contact with the square bar, so that the square bar is pushed by the extrusion plate. The square bar drives the secondary thoracoscope to rotate in a small circle along the concave frame. Step 3: Pneumatic cleaning. When the moving plate moves to the circular tube position of the connecting shell, the airflow will enter the inside of the circular tube, and then enter the inside of the arc-shaped bucket through the circular tube. The setting of the arc-shaped bucket can diffuse the range of the airflow jet. During the process of the airflow jetting outward, the secretions inside the patient's chest cavity can be jetted. When the rotating ring rotates, the rotating ring drives the round rod to rotate, the round rod drives the special-shaped frame to rotate, and the special-shaped frame drives the cleaning strip to rotate. During the rotation of the cleaning strip, the mucus adhered to the mirror surface of the main thoracoscope can be cleaned; Step 4: Auxiliary monitoring. During the process of the moving plate moving to the circular tube position of the connection shell, the spring accumulates elastic potential energy. When the airflow inside the fixed shell is completely discharged, the spring releases the elastic potential energy, and the spring drives the moving plate to perform a reset movement, thereby causing the sub-thoracoscope to rotate in the opposite direction. When the airflow inside the fixed shell is completely discharged, the extrusion plate no longer squeezes the square bar, and is elastically deformed by the arc spring. The arc spring drives the square bar to move, and the square bar drives the sub-thoracoscope to perform a reset movement; the sub-thoracoscope rotates around the inner wall of the concave frame and performs a small reciprocating rotation.
