[0002] In the field of modern medicine, single-port thoracoscopic surgery has become an important development direction in thoracic surgery due to its advantages such as minimal trauma and rapid recovery. During the operation, it usually requires two doctors to work together. The lead surgeon is responsible for guiding the surgical operation, while the assistant surgeon adjusts the lens angle according to the lead surgeon's instructions by using forceps to change the angle. However, the lens adjustment is not a high-frequency operation throughout the entire operation. Often, the lead surgeon adjusts the lens to the appropriate angle after determining the surgical site before starting the operation. This operation mode requires the assistant surgeon to pay extra attention to the lens position. At the same time, direct manual adjustment carries the risk of misoperation, which may cause the lens to move a large range and affect the progress of the operation. In addition, the thoracoscopic endoscope lacks support at the bottom, and the area near the incision protector is often temporarily pulled with sutures, resulting in insufficient lens stability and increasing the risk of surgical operation.

[0045] The moving groove 2033-1 is fixed with a stop block 2035, one side of the locking block 2034 is fixed with a first spring 2036, and the other end of the first spring 2036 is fixed on the stop block 2035. The side surface of the locking block 2034 away from the stop block 2035 is an inclined surface arranged from bottom to top and outwardly inclined. The number of the first spring 2036 is two, corresponding to the locking block 2034 one by one, the first spring 2036 applies a continuous thrust force to the locking block 2034, ensuring that under the condition of no other external force, the inclined end of the locking block 2034 will protrude from the surface of the mounting plate 2033, and the first spring 2036 is also used for resetting the locking block 2034.

[0046] Specifically, the mounting plate 2033 is provided with a sliding groove 2033-2, the sliding groove 2033-2 is provided with a pushing block 2037, one end of the pushing block 2037 is fixed with a pressing block 2038, one end of the pressing block 2038 extends to the outside of the mounting plate 2033, and is used to drive the pushing block 2037 to move, and the pushing block 2037 is used to release the clamping of the locking block 2034 and the locking groove 2031-1.

[0047] The second spring 2039 is fixed on one side of the pressing block 2038 and clamped between the pressing block 2038 and the sliding groove 2033-2. The bottom of the pushing block 2037 is provided with a guide slope for sliding the locking block 2034 out of the locking groove 2031-1 when the pressing block 2038 moves upward.

One end of the pushing block 2037 is inclined. When the pressing block 2038 moves upward, the pressing block 2038 will drive the pushing block 2037 to move upward. At this time, the inclined end surface of the pushing block 2037 will press the force receiving groove 2034-1, so that the second spring 2039 is compressed, and the locking block 2034 will move away from the locking groove 2031-1, thereby releasing the position locking of the mounting plate 2033 and the mounting block 2031.

[0049] Specifically, the fixing assembly 200 further comprises an auxiliary part 204 located in the spherical seat 2024, which is used to lock the position of the ball 2023, and further lock the position of the thoracoscope 101, so as to avoid the position deviation during the operation.

[0050] The auxiliary part 204 comprises an extrusion plate 2041 slidably arranged in the spherical seat 2024. The extrusion plate 2041 is provided with a plurality of friction blocks on the side close to the ball 2023, which is used to enhance the friction between the ball 2023 and the extrusion plate 2041. By extruding the ball 2023 with the extrusion plate 2041, the relative position between the ball 2023 and the spherical seat 2024 is locked by the friction force. The extrusion plate 2041 is connected with a first threaded column 2042 through a bearing on one side. The spherical seat 2024 is fixed with a first threaded sleeve 2043. The first threaded column 2042 is threadedly connected with the first threaded sleeve 2043. When the first threaded column 2042 is rotated, the first threaded column 2042 will move along the direction of the first threaded sleeve 2043, so as to move towards the ball 2023, so as to extrude the ball 2023 with the extrusion plate 2041, and further lock the relative position between the ball 2023 and the spherical seat 2024. The angle of the ball 2023 is fixed, so as to lock the angle of the bottom end of the thoracoscope 101, and further lock the position of the thoracoscope 101 as a whole.

[0051] Specifically, the extrusion block 2044 is arranged in the mounting sleeve 2021 and is used to lock the relative position of the thoracoscope 101 and the mounting sleeve 2021. The extrusion block 2044 is arranged with a plurality of friction blocks near the side of the thoracoscope 101, so as to increase the friction between the extrusion block 2044 and the thoracoscope 101.

In this way, the locking state of the mounting sleeve 2021 and the thoracoscope 101 is controlled.

[0053] Embodiment 3

[0054] Reference Figures 1-8 This embodiment is based on the previous two embodiments.

[0055] Specifically, the sleeve 2017 is fixed on the thoracoscope 101, and the fixed rods 2018 are fixed on the sleeve 2017. The number of the fixed rods 2018 is three, which are uniformly distributed in a circle. The fixed sleeve 2016 is in a circular ring shape, but its inside is hollow. The ends of the three fixed rods 2018 away from the sleeve 2017 are connected with the end points to form a circle. The size of the circle is smaller than the size of the inner circle of the fixed sleeve 2016. Therefore, the whole formed by the sleeve 2017 and the three fixed rods 2018 can slide in the fixed sleeve 2016.

[0056] Specifically, the protrusions 2019 are fixed on the inner wall of the fixed sleeve 2016. The number of the protrusions 2019 is multiple. The protrusions 2019 are used to increase the friction between the fixed rods 2018 and the fixed sleeve 2016, and to make the inner wall of the fixed sleeve 2016 and the fixed rods 2018 have an adjustable space.

[0057] When the irradiation angle of the thoracoscope 101 is adjusted, the position of the sleeve 2017 on the fixed rods 2018 is adjusted, so as to adjust the position of the lower end of the thoracoscope 101 close to the incision protector 102. The adjustment angle will not be too large. Due to the principle of the lever, the fulcrum is located at the position of the fixed sleeve 2016. When the angle of the lower end of the thoracoscope 101 needs to be adjusted in a small range, the angle of the upper end only needs to be adjusted in a smaller range. After the adjustment is completed, the first threaded column 2042 and the second threaded column 2045 are rotated, so as to lock the position angle of the lower end of the thoracoscope 101. In this way, the whole position of the thoracoscope 101 is locked.

[0058] When the angle needs to be adjusted, the first threaded column 2042 and the second threaded column 2045 are reversely rotated, so that the position of the lower end of the thoracoscope 101 can be changed, but the thoracoscope 101 is still pressed at the lower end, so that when the adjustment is made, frictional damping is applied to the movement of the thoracoscope 101, avoiding large position changes of the thoracoscope 101.

[0059] Specifically, the side of the pressing block 2044 is fixed with a guide column 2047, and the installation sleeve 2021 is provided with a guide groove 2021-1, and the guide column 2047 and the guide groove 2021-1 are slidingly connected. The guide column 2047 is inserted into the guide groove 2021-1, which ensures that when the second threaded column 2045 is rotated, the pressing block 2044 can move smoothly.

[0060] Specifically, the bottom plate 2011 is fixed with a rectangular block 20110, and the horizontal plate 2012 is fixed with a rectangular frame 20111, and the rectangular block 20110 and the rectangular frame 20111 are longitudinally and slidingly connected. The rectangular block 20110 is inserted into the rectangular frame 20111, and through the matching of the two, the relative rotation of the bottom plate 2011 and the horizontal plate 2012 is limited, so as to ensure that when the rotating sleeve 2015 is rotated, the distance between the bottom plate 2011 and the horizontal plate 2012 can be accurately adjusted, and then the height of the thoracoscope 101 is adjusted. When the horizontal plate 2012 needs to be rotated relative to the bottom plate 2011, the rectangular block 20110 and the rectangular frame 20111 can be relatively staggered.

[0061] In use, the installation sleeve 2021 is sleeved on the bottom of the thoracoscope 101, and then the rotating sleeve 2015 is rotated to adjust the distance between the bottom plate 2011 and the horizontal plate 2012, and then the height of the thoracoscope 101 is adjusted, so that the thoracoscope 101 enters the body through the incision protector 102, and then the mounting plate 2033 is inserted into the mounting block 2031, and the inclined surface of the locking block 2034 will first contact the end surface of the mounting block 2031, and the locking block 2034 will move into the moving groove 2033-1, without hindering the clamping of the mounting plate 2033 and the mounting block 2031. With the further downward movement of the mounting plate 2033, when the locking block 2034 and the locking groove 2031-1 are coaxial, they will be clamped, so that the relative position of the mounting plate 2033 and the mounting block 2031 is locked, and the relative position of the spherical seat 2024 and the incision protector 102 is fixed.

[0062] After adjusting the relative position of the thoracoscope 101 and the mounting sleeve 2021, after the adjustment is completed, the second threaded column 2045 is rotated, the extrusion block 2044 is close to the thoracoscope 101, the position of the mounting sleeve 2021 and the thoracoscope 101 is locked, then the angle of the thoracoscope 101 is adjusted through the sphere 2023 and the spherical seat 2024 in a small range, after the adjustment is completed, the first threaded column 2042 is rotated, the first threaded column 2042 will move along the direction of the first threaded sleeve 2043, so as to close to the sphere 2023, so as to extrude the sphere 2023 by the extrusion plate 2041, and then the relative position of the sphere 2023 and the spherical seat 2024 is locked, the angle of the sphere 2023 is fixed, so as to lock the angle of the bottom end of the thoracoscope 101, and then the position of the whole thoracoscope 101 is locked.
