[0048] This invention provides a multifunctional auxiliary puncture device for cardiothoracic surgery. It features a designed sterilization mechanism for automatic sterilization, improving surgical efficiency and reducing the burden on medical staff. It assists surgeons in puncture procedures without affecting pre-puncture anesthesia or post-puncture coverage, allowing for needle angle adjustment to improve accuracy and surgical outcomes. Before any puncture procedure, the auxiliary puncture device requires thorough sterilization to ensure surgical safety.

[0049] This application provides a multifunctional auxiliary puncture device for cardiothoracic surgery, hereinafter referred to as the auxiliary puncture device, such as... Figures 1 to 4 As shown, the auxiliary puncture device includes a fixing component 1, a moving cylinder 2, a positioning component 3, and a sterilizing cylinder 41. The fixing component 1 includes a fixing cylinder 11 with an operating groove 12. Guide rails 13 are provided on both sides of the operating groove 12. The moving cylinder 2 is slidably connected to the guide rails 13 and can slide along the extension direction of the guide rails 13. The inner cavity of the moving cylinder 2 is connected to the operating groove 12, and an opening 21 is provided on the cylinder wall to expose the operating area 120 of the operating groove 12 located inside the cylinder wall. The positioning component 3 includes a positioning cylinder 31 and a first rotating shaft 32 fixedly connected. The positioning cylinder 31 is disposed in the inner cavity of the moving cylinder 2, and the first rotating shaft 32 is rotatably connected to the moving cylinder 2. The sterilizing cylinder 41 is disposed in the inner cavity of the moving cylinder 2 and is configured to reciprocate within the operating area 120.

[0050] In this embodiment, the fixing cylinder 11 is bracket-shaped, including square brackets and round brackets. When connected to a patient, the patient's back is placed inside the opening 21 of the fixing cylinder 11, and the puncture point on the back is exposed through the operating groove 12. Connecting buckles 111 are provided at both ends of the fixing cylinder 11. A flexible fixing strap, located on the patient's chest or chair back, passes through the connecting buckles 111 to fix the fixing cylinder 11 to the patient's back, reducing the probability of relative movement between the fixing cylinder 11 and the patient during puncture, and improving puncture accuracy and stability.

[0051] In this embodiment, after the fixing cylinder 11 is fixed to the patient's back, the moving cylinder 2 is driven to move along the extension direction of the guide rail 13, so that the puncture point on the back is placed within the operating area 120 inside the moving cylinder 2. The positioning cylinder 31 is placed inside the moving cylinder 2 and is used to connect with the puncture element 7. By adjusting the position of the moving cylinder 2, the positions of the positioning cylinder 31 and the puncture element 7 are adjusted so that the position of the puncture element 7 corresponds to the puncture point, thereby improving puncture accuracy, increasing the working range of the auxiliary puncture device, and enabling puncture operations at different positions, thus expanding the working range of the auxiliary puncture device. The positioning cylinder 31 can also be rotated by the first rotating shaft 32 to adjust the positioning cylinder 31 to a preset angle, thereby presetting the puncture angle of the puncture element 7, reducing the probability of puncture accuracy being affected by shaking or lack of experience during the puncture process, reducing the difficulty of the operation, and improving the surgical effect.

[0052] In this embodiment, the movable cylinder 2 can be cylindrical or frustum-shaped; when the movable cylinder 2 is frustum-shaped, the number of side edges is greater than or equal to four. When the fixed cylinder 11 is bracket-shaped, the guide rail 13 is also bracket-shaped, and the movable cylinder 2 can be moved by hydraulic or pneumatic transmission. When the fixed cylinder 11 is square bracket-shaped, it includes a horizontal section and a vertical section fixedly connected, with the vertical section located on both sides of the horizontal section. When fixed, the horizontal section is located on the patient's back, and the vertical section is located on both sides of the patient. The movable cylinder 2 is set in the horizontal section, and at this time, the movable cylinder 2 can be moved by electric, hydraulic, or pneumatic transmission. The electric transmission method includes, but is not limited to, electric push rods and gears.

[0053] In this embodiment, after the angle of the positioning cylinder 31 is adjusted, a sterile drape is laid on the side of the fixed cylinder 11 away from the patient's back. The drape has an opening in the center. During operation, the opening is aligned with the moving cylinder 2, and the remaining portion covers the patient's body and surrounding area, forming a physical barrier to ensure the surgery is performed in a relatively sterile environment, reducing microbial contamination and lowering the risk of infection. The shape and size of the opening can be set according to the shape and size of the moving cylinder 2, and can be circular, elliptical, or polygonal.

[0054] In this embodiment, after the sterile drape is laid, the sterile tube 41 is driven to contact the skin within the operating area 120 and moves back and forth within the operating area 120 to disinfect the puncture point and its surrounding area. The disinfection process can be observed through the opening 21. After disinfection, the sterile tube 41 returns to its original position, and the doctor can insert or extend their hand into or out of the moving tube 2 through the opening 21 to perform anesthesia, thereby reducing patient discomfort.

[0055] In this embodiment, after anesthesia, the puncture device 7 is assisted by the positioning tube 31 for puncture, followed by fluid aspiration. After aspiration, the doctor can remove the needle from above the moving tube 2, while simultaneously applying pressure to the puncture site with cotton balls or gauze through the opening 21 for 5 to 10 minutes (to prevent bleeding or pneumothorax). Once bleeding stops, the puncture device 7 is disinfected again with the sterilization tube 41, or manually disinfected by holding an iodine-soaked cotton ball through the opening 21. After disinfection, the puncture site is covered with sterile gauze and secured with tape to keep it dry and clean. The auxiliary puncture device can be removed after applying pressure to the puncture site with cotton balls or gauze, or after securing with tape.

[0056] In this embodiment, automatic disinfection during puncture surgery is achieved through the disinfection tube 41, eliminating the need for manual operation by medical staff. This saves time, reduces the burden on medical staff, and allows doctors to concentrate on the puncture operation, thereby improving surgical outcomes and efficiency. The auxiliary puncture device can assist doctors in performing puncture operations without affecting pre-puncture anesthesia and post-puncture coverage, and it also allows for adjustment of the puncture needle angle, which can improve puncture accuracy and surgical outcomes.

[0057] In some embodiments, the fixation component 1 further includes a filler (not shown), which is disposed on both sides of the operating groove 12 and located on the side of the fixation cylinder 11 opposite to the moving cylinder 2. The filler is used to fill the gap between the fixation cylinder 11 and the patient's back, allowing the fixation cylinder 11 to better conform to the human body, improving the fixation stability and comfort of the fixation cylinder 11, reducing the probability of relative movement between the fixation cylinder 11 and the patient during puncture, and improving puncture accuracy and stability. The filler includes an air bladder, which can be used either by moving the moving cylinder 2 to the puncture point first and then inflating the air bladder, or by inflating the air bladder first and then moving the moving cylinder 2 to the puncture point, depending on actual needs, without interference between the two operations.

[0058] In some embodiments, such as Figure 7 and Figure 8 As shown, a sliding channel 130 is provided inside the guide rail 13. The fixing assembly 1 also includes an inflation / deflation component 14, a first magnetic component 131, and a second magnetic component 132. The inflation / deflation component 14 is disposed at one end of the fixing cylinder 11 and is connected to the sliding channel 130 through a conduit 141. The first magnetic component 131 is disposed inside the sliding channel 130 and is slidably connected to the guide rail 13. The second magnetic component 132 is disposed on both sides of the moving cylinder 2 and has a magnetic attraction with the first magnetic component 131.

[0059] In this embodiment, air is pumped into the sliding channel 130 through the inflation / deflation device 14 at one end of the fixed cylinder 11. Under the pressure of the air, the first magnetic component 131 in the sliding channel 130 moves towards the other end of the fixed cylinder 11, while the second magnetic component 132 moves synchronously under the influence of magnetic attraction, thus moving the moving cylinder 2. The moving cylinder 2 and the guide rail 13 can also be connected through the magnetic attraction between the first magnetic component 131 and the second magnetic component 132. The two adjacent sides of the first magnetic component 131 and the second magnetic component 132 are magnetic attraction surfaces. The surfaces of the two magnetic components other than the magnetic attraction surfaces are coated with magnetic shielding material, which can reduce the impact of the two magnetic components on the structure of other metal materials and improve the working stability of the auxiliary puncture device.

[0060] In this embodiment, the inflation / deflation component 14 includes an air pump. A sealing gasket or sealing ring is provided between the first magnetic component 131 and the sliding component to improve the airtightness of the sliding channel 130 and enhance the movement stability of the moving cylinder 2. The second magnetic component 132 can be disposed in the middle region on both sides of the moving cylinder 2 to ensure balanced force distribution on the moving cylinder 2 and improve movement stability. Both the first magnetic component 131 and the second magnetic component 132 can be magnets, or one can be a magnet and the other can be a ferromagnetic metal, such as iron, cobalt, nickel, or their alloys.

[0061] In some embodiments, such as Figure 1 and Figure 4As shown, a locking plate 24 is hinged to the lower part of the movable cylinder 2. The locking plate 24 is located on both sides of the operating groove 12. The locking plate 24 can rotate relative to the movable cylinder 2 to engage with the guide rail 13, or it can rotate to disconnect from the guide rail 13. A second magnetic component 132 is provided on the locking plate 24. The engagement of the locking plate 24 with the guide rail 13 can further improve the connection stability between the movable cylinder 2 and the fixed cylinder 11; the locking plate 24 can also realize the detachable connection between the movable cylinder 2 and the fixed cylinder 11, so as to facilitate the storage, transportation and maintenance of the auxiliary puncture device.

[0062] In some embodiments, the filler is an airbag, such as Figure 4 and Figure 6 As shown, the guide rail 13 has spaced threaded holes and baffle holes on the side away from the filler. The fixing assembly 1 also includes an air passage 18, an adjusting screw 15, and a baffle 17. The air passage 18 is located at one end of the fixing cylinder 11 and is used to connect the sliding channel 130 and the filler. The two ends of the adjusting screw 15 have different thread directions. One end passes through the threaded hole and is placed in the sliding channel 130, and is connected to a plug 16. Along the extension direction of the adjusting screw 15, the projection of the plug 16 covers the projection of the air passage 18 inlet. One end of the baffle 17 is threadedly connected to the adjusting screw 15 located outside the sliding channel 130, and the other end passes through the baffle hole and is placed in the sliding channel 130. The baffle 17 and the guide rail 13 are respectively connected to the adjusting screw 15 with different thread directions.

[0063] In this embodiment, the baffle 17 includes a first baffle and a second baffle fixedly connected. The first baffle and the second baffle are arranged vertically. The portion of the first baffle passing through the baffle hole is placed inside the sliding channel 130. The second baffle is threadedly connected to the portion of the adjusting screw 15 that is outside the sliding channel 130. The extending direction of the first baffle is parallel to the extending direction of the central axis of the adjusting screw 15, and the extending direction of the second baffle is perpendicular to the extending direction of the central axis of the adjusting screw 15.

[0064] In this embodiment, the inflation / deflation device 14 can be used to fill the filler and drive the first magnetic component 131 via the air passage 18, adjusting screw 15, plug 16, and baffle 17. Specifically, when the moving cylinder 2 is moved to the puncture point first and then the airbag is inflated, the adjusting screw 15 is rotated to screw it further into the sliding channel 130 until the plug 16 at one end is tightly abutted against the inlet of the air passage 18, thus sealing the inlet of the air passage 18 and preventing airflow from entering the filler through the air passage 18. During the process of the adjusting screw 15 being screwed into the sliding channel 130, due to the different screw directions, the baffle 17 moves away from the fixed cylinder 11, opening the sliding channel 130. At this time, the inflation / deflation device 14 is activated, allowing airflow to flow into the sliding channel 130 to drive the first magnetic component 131 to move, thereby moving the moving cylinder 2.

[0065] In this embodiment, when inflating the airbag, the adjusting screw 15 is rotated in the opposite direction to allow it to extend further out of the sliding channel 130. Due to the different screw directions, the baffle 17 moves closer to the fixed cylinder 11 until the baffle 17 is tightly abutted against the bottom surface of the sliding channel 130, thus sealing the sliding channel 130 and preventing airflow from diverting into it. The adjusting screw 15 extends out of the sliding channel 130, causing the plug 16 at one end to move away from the inlet of the air passage 18. At this time, the inflation / deflation device 14 is activated, the sliding channel 130 is closed, and the airflow provided by the inflation / deflation device 14 enters the filler through the air passage 18, causing the filler to expand and fill the gaps.

[0066] In this embodiment, when the airbag is inflated first and the moving cylinder 2 is moved to the puncture point, the rotation direction of the adjusting screw 15 is opposite to that described above, and will not be elaborated here. The working mode of the auxiliary puncture device can be adjusted by adjusting the rotation direction and screw depth of the adjusting screw 15. The structure is simple and the adjustment method is simple and convenient, which can improve the ease of adjustment and application of the auxiliary puncture device.

[0067] In this embodiment, seals are provided at both the threaded hole and the baffle hole to ensure the sealing of the sliding channel 130 and the airflow transmission effect. A seal is provided between the baffle 17 and the sliding channel 130 to ensure the sealing effect of the baffle 17 on the sliding channel 130 and improve the stability of the auxiliary puncture device's working mode adjustment. The material of the plug 16 includes, but is not limited to, silicone, rubber, and their compounds.

[0068] In some embodiments, such as Figure 4 , Figure 7 and Figure 11 As shown, the auxiliary puncture device also includes a first telescopic member 42, a disinfection plate 45, and a transmission tube. The first telescopic member 42 is disposed in a first moving groove 22 on the wall of the moving cylinder 2, and includes a fixed end and a telescopic end. The fixed end is connected to the first moving groove 22, and the telescopic end extends in a direction parallel to the extension direction of the moving cylinder 2. The telescopic end is connected to a first connecting rod 43, and a liquid storage chamber 44 is disposed on the side of the first connecting rod 43 away from the moving cylinder 2. The disinfection plate 45 is disposed inside the moving cylinder 2, with one end connected to the disinfection cylinder 41 and the other end hinged to the first connecting rod 43. The transmission tube passes through the first connecting rod 43 and the disinfection plate 45, with one end communicating with the liquid storage chamber 44 and the other end connected to the disinfection cylinder 41. The liquid storage chamber 44 is used to store disinfectant, such as iodine solution, or is connected to a container storing disinfectant. The disinfectant is transmitted to the disinfection cylinder 41 through the transmission tube and then applied to the periphery of the puncture point via the disinfection cylinder 41.

[0069] In this embodiment of the application, before performing the disinfection operation, such as Figure 7 and Figure 8As shown, the disinfection plate 45 and the disinfection cylinder 41 are located on the right side of the moving cylinder 2 and close to it, in the initial state, at which time the first telescopic member 42 has its maximum extension. During the disinfection operation, the first telescopic member 42 is driven to retract by a motor or other driving component. The telescopic end moves downward, causing the first connecting rod 43 to move downward. Under the influence of the pressure provided by the first connecting rod 43 and the friction between the disinfection cylinder 41 and the patient's skin, one end of the disinfection plate 45 moves downward with the first connecting rod 43 and rotates relative to the first connecting rod 43, while the other end drives the disinfection cylinder 41 to roll from one side of the operation area 120 to the other side, disinfecting the patient's skin in the operation area 120 with the disinfectant solution on the disinfection cylinder 41; Figure 11 and Figure 12 As shown, the disinfection cylinder 41 moves to the left side of the moving cylinder 2 and is in the disinfection state.

[0070] In this embodiment, the first telescopic member 42 is extended by a motor or other driving component. The upward movement of the telescopic end causes the first connecting rod 43 to move upward. Under the force provided by the first connecting rod 43, the disinfection plate 45 and the disinfection cylinder 41 move back to their original positions, returning to their initial state. Through the cooperation of the first telescopic member 42, the first connecting rod 43, the disinfection plate 45, and the disinfection cylinder 41, automatic disinfection of the skin in the operating area 120 can be achieved without manual operation by medical staff. This saves time, reduces the burden on medical staff, and allows doctors to concentrate on the puncture operation, improving surgical results and efficiency.

[0071] In some embodiments, the auxiliary puncture device further includes a limiting block 430, which is fixedly connected to the first connecting rod 43 and slidably connected to the movable cylinder 2. The sidewall of the movable cylinder 2 is located between the limiting block 430 and the disinfection plate 45. The limiting block 430 is used to limit the length of the first connecting rod 43 passing through the first movable groove 22, thereby improving the movement stability of the first connecting rod 43 and the stability of the disinfection operation. The widths of both the disinfection plate 45 and the first limiting block 430 are greater than the width of the first movable groove 22, preventing the first connecting rod 43 from disengaging from the first movable groove 22 and improving the reliability of the auxiliary puncture device.

[0072] In some embodiments, such as Figure 14 As shown, the disinfection cylinder 41 and the disinfection plate 45 are rotatably connected by the second rotating shaft 46. The disinfection cylinder 41 includes a plurality of sub-cylinders 411 that are evenly and spaced around the periphery of the second rotating shaft 46. Each sub-cylinder 411 is connected to the second rotating shaft 46 by the third rotating shaft 47. The rotation axes of the second rotating shaft 46 and the third rotating shaft 47 are parallel.

[0073] In this embodiment, during the movement of the disinfection cylinder 41 from the right side to the left side of the moving cylinder 2, the rotation of the second rotating shaft 46 is limited. At this time, the sub-cylinder 411 closest to the operating area 120 rolls under the influence of friction with the patient's skin. The circumference of the sub-cylinder 411 can be set according to the length of the operating area 120, so that the sub-cylinder 411 completes one rotation to disinfect the skin of the operating area 120. After the disinfection cylinder 41 moves to the left side, the second rotating shaft 46 is driven to rotate, causing multiple sub-cylinders 411 to rotate synchronously, realizing the switching of the position of the sub-cylinders 411. Then, the rotation of the first rotating shaft 32 is limited, and the disinfection cylinder 41 is driven to return from the left side of the moving cylinder 2 to the initial position on the right side. During this process, the new sub-cylinder 411 with disinfectant solution performs a second disinfection of the skin of the operating area 120.

[0074] In this embodiment, the reciprocating movement of the disinfection cylinder 41 allows for two applications of disinfectant. Different sub-cylinders 411 achieve two rounds of disinfection at the puncture site. Furthermore, the rolling disinfection of the sub-cylinders 411 avoids repeated disinfection of different areas by the same disinfection device. Compared to manual disinfection, this improves disinfection effectiveness and efficiency, reduces the risk of postoperative infection, and enhances surgical outcomes and efficiency. The number of sub-cylinders 411 can be set according to the actual number of disinfection cycles; this application does not limit this. When disinfection is performed once, the disinfection cylinder 41 can be moved to the left side before contacting the disinfection cylinder 41 with the disinfectant solution to the patient's skin. This prevents the disinfection plate 45 from getting stuck in the operating area 120 after disinfection, thus hindering subsequent operations.

[0075] In some embodiments, such as Figure 10 , Figure 14 and Figure 15 As shown, the auxiliary puncture device also includes a switching component 5, which includes a second moving groove 23, a switching plate 52, and two second connecting rods 56. The second moving groove 23 is disposed on the wall of the moving cylinder 2, and a first bar magnet 51 is disposed at both ends. The magnetic poles of the two first bar magnets 51 on the side near the disinfection plate 45 are opposite. The switching plate 52 passes through the second moving groove 23 and is connected to the disinfection plate 45. A receiving cavity 53 is disposed in the switching plate 52 and the disinfection plate 45. A one-way roller 54 is disposed at both ends of the receiving cavity 53 in the switching plate 52. The one-way roller 54 is connected to the second rotating shaft 46 through a transmission belt 55. One end of the two second connecting rods 56 is fixedly connected to the one-way roller 54, and the other end extends out of the receiving cavity 53 and is connected to a plurality of rotating rods 57 around its periphery. A second bar magnet is disposed on both opposite sides of each rotating rod 57. The magnetic poles of each second bar magnet on the side away from the rotating rod 57 are the same.

[0076] In the embodiments of this application, such as Figure 10 As shown, one of the two first bar magnets 51 is located above the second moving slot 23 (hereinafter referred to as the upper magnet), and the other is located below the second moving slot 23 (hereinafter referred to as the lower magnet). (Here, the vertical direction is...)Figure 10 (The vertical direction shown in the diagram does not represent the actual vertical direction during operation.) Both the upper and lower magnets include N and S poles. The magnetic poles of the two first bar magnets 51 on the side closest to the disinfection plate 45 are opposite, as shown in the diagram. Figure 16 and Figure 17 As shown, the upper magnet, closer to the left end of the disinfection plate 45, is the N pole, and the lower magnet, closer to the left end of the disinfection plate 45, is the S pole.

[0077] In this embodiment, the magnetic poles of each second bar magnet at the end opposite to the rotating rod 57 are the same, and can all be either S pole or N pole. For example... Figure 16 and Figure 17 As shown, the magnetic poles of the second bar magnet at the end facing away from the rotating rod 57 are all S poles. Except for the side facing away from the rotating rod 57, the other sides of the second bar magnet are provided with a magnetic shielding layer or coated with magnetic shielding material, so that each second bar magnet emits magnetic force with only one face outward, reducing the influence between adjacent second bar magnets and improving the stability of the position switching of the sub-cylinder 411.

[0078] In this embodiment, the switching plate 52 is perpendicular to the disinfection plate 45. As the disinfection plate 45 moves up and down and rotates, it simultaneously drives the switching plate 52 to move up and down and rotate synchronously. Support rollers are provided on both sides of the transmission belt 55 at the connection point between the switching plate 52 and the disinfection plate 45 to improve the stability of the transmission belt 55's movement. The one-way roller 54 prevents the transmission belt 55 from moving during the rolling of the sub-cylinder 411, thus improving the working stability of the disinfection cylinder 41.

[0079] In the embodiments of this application, such as Figure 7 , Figure 9 and Figure 16 As shown, after the disinfection cylinder 41 moves from the left side to the right side of the moving cylinder 2, the position of the sub-cylinder 411 can be switched by the magnetic force between the upper magnet and the second bar magnet located near the disinfection plate 45. Specifically, the second bar magnet with the S pole attracts the N pole of the upper magnet, causing the rotating rod 57, the second connecting rod 56, and the one-way roller 54 to rotate clockwise. The one-way roller 54 drives the second rotating shaft 46 to rotate through the transmission belt 55, thereby switching the position of the sub-cylinder 411.

[0080] In the embodiments of this application, such as Figure 11 , Figure 13 and Figure 17 As shown, after the disinfection cylinder 41 moves from the right side to the left side of the moving cylinder 2, the position of the sub-cylinder 411 can be switched again by the magnetic force between the lower magnet and the second bar magnet located away from the disinfection plate 45. The principle is the same as described above and will not be repeated here. The lower magnet is tilted to correspond to the position of the switching plate after rotation, so as to better drive the rotating rod 57 to rotate.

[0081] In this embodiment, the rotation direction of the rotating rod 57, the second connecting rod 56, and the one-way roller 54 can be changed by altering the magnetic pole of the end of the second bar magnet facing away from the rotating rod 57, thereby changing the switching direction of the sub-cylinder 411 and improving the applicability of the auxiliary puncture device. The number of rotating rods 57 on the second connecting rod 56 can be set to correspond to the number of sub-cylinders 411, so that the rotation switching of one rotating rod 57 corresponds to the rotation switching of one sub-cylinder 411.

[0082] In this embodiment, the second rotating shaft 46 can be directly driven to rotate by a motor or other driving component to achieve the switching of the sub-tube 411; alternatively, the second rotating shaft 46 can be driven to rotate by the switching component 5 to achieve the switching of the sub-tube 411. The automatic switching function of the sub-tube 411 allows for timely and rapid replacement of sterilization components during surgery, eliminating the need for medical staff to manually support the puncture site or frequently change sterilization components, saving time, ensuring the continuity of sterilization work, making the surgical procedure smoother, and improving surgical efficiency. Medical staff can also concentrate more on the surgical operation itself, reducing potential errors caused by distractions such as changing sterilization components, alleviating their workload, and helping them maintain a better mental state and operational accuracy during surgery, thus improving the overall quality of medical services.

[0083] In some embodiments, such as Figure 15 As shown, the transmission belt 55 is provided with a plurality of evenly spaced limiting holes 58, and the side of the switching plate 52 away from the disinfection plate 45 is provided with a fixing pin 59. During the process of the disinfection cylinder 41 moving left and right and the switching plate 52 moving up and down, the fixing pin 59 extends into the receiving cavity 53 and engages with one of the limiting holes 58 to limit the movement of the transmission belt 55 during the rolling process of the sub-cylinder 411, reduce the probability of the sub-cylinder 411 switching prematurely during rolling and affecting the disinfection effect, and improve the working stability of the disinfection cylinder 41.

[0084] In some embodiments, such as Figure 10 As shown, the auxiliary puncture device also includes a pressure cylinder 6, which is connected to the movable cylinder 2 and is respectively positioned on both sides of the operating area 120 along with the disinfection cylinder 41. After the fixed cylinder 11 is fixed to the patient's back, the pressure cylinder 6 is in close contact with the skin on the left side of the puncture point. After the disinfection cylinder 41 moves from left to right to complete the disinfection, it applies a rightward pulling force to the patient's skin, causing the skin to unfold. This, combined with the pressure cylinder 6, presses and fixes the skin on both sides of the operating area 120, fully exposing the puncture point to facilitate subsequent puncture operations and improve puncture accuracy.

[0085] In some embodiments, the pressure cylinder 6 and the movable cylinder 2 are rotatably connected via a rotating shaft, one end of which is also connected to a motor. Starting the motor drives the rotating shaft to rotate, which in turn rotates the pressure cylinder 6, applying a leftward pulling force to the patient's skin, causing the skin to unfold. This, combined with the sterilization cylinder 41, presses and fixes the skin on both sides of the operating area 120, fully exposing the puncture point to facilitate subsequent puncture procedures and improve puncture accuracy.

[0086] In some embodiments, such as Figure 1 , Figure 5 , Figure 7 and Figure 11 As shown, the movable cylinder 2 includes two openings 21, two positioning holes, and two first rotating shafts 32 respectively disposed on both sides of the operating groove 12. The positioning holes are disposed above the openings 21, and the first rotating shafts 32 pass through the positioning holes and are connected to the positioning cylinder 31. Limiting plugs 33 are slidably connected to both first rotating shafts 32. The limiting plugs 33 can move between the first rotating shaft 32 and the positioning holes to limit the rotation of the first rotating shaft 32 relative to the positioning holes. The arrangement of the two openings 21, two positioning holes, and two first rotating shafts 32 can balance the force on both sides of the positioning cylinder 31, improving the stability of fixing the piercing piece 7. At this time, the positioning holes are round holes, used to provide support and rotation space for the first rotating shafts 32.

[0087] In this embodiment, when the angle of the positioning cylinder 31 needs to be adjusted, the moving limiting plug 33 is disengaged from the positioning hole, allowing the first rotating shaft 32 to drive the positioning cylinder 31 to rotate. Specifically, the portion of the first rotating shaft 32 located outside the moving cylinder 2 is manually rotated, causing the positioning cylinder 31 to rotate left and right, thus adjusting the angle of the puncture component 7. After the positioning cylinder 31 is adjusted to the preset angle, the limiting plug 33 is manually slid to engage between the first rotating shaft 32 and the positioning hole, limiting the rotation of the first rotating shaft 32 and fixing the angle of the positioning cylinder 31, thereby fixing the angle of the puncture component 7 and improving puncture accuracy and stability. The fixing method is simple and convenient, requiring no professional training to operate, reducing the operational difficulty of the auxiliary puncture device, improving operational efficiency, and saving operation time. The left and right directions refer to the movement direction of the moving cylinder 2.

[0088] In some embodiments, such as Figure 18 , Figure 20 and Figure 21As shown, the movable cylinder 2 includes two positioning holes 35 and two first rotating shafts 32. The positioning holes 35 are elongated holes, extending parallel to the extension direction of the first moving groove 22. An adjusting screw 36 is provided on the upper surface of the movable cylinder 2, and a threaded hole communicating with the positioning holes 35 is also provided on the movable cylinder 2. The adjusting screw 36 passes through the threaded hole and is threadedly connected to the movable cylinder 2, with a portion located within the positioning hole 35. The extension direction of the adjusting screw 36 is parallel to the extension direction of the elongated hole. A connecting ball 37 is provided at one end of the adjusting screw 36 located within the positioning hole 35. A rotating ball 38 is provided inside the connecting ball 37, and the rotating ball 38 is rotatably connected to the connecting ball 37. Both the rotating ball 38 and the connecting ball 37 are provided with through holes, through which the first rotating shaft 32 passes, with a portion of its rod extending out of the movable cylinder 2.

[0089] In this embodiment, the positioning hole 35 provides movement space for the first rotating shaft 32, and the adjusting screw 36 provides support for the first rotating shaft 32. By rotating the ball 38 and connecting ball 37, the first rotating shaft 32 can rotate left and right within the positioning hole 35, causing the positioning cylinder 31 to rotate left and right, thus adjusting the angle of the piercing element 7 in the left-right direction. It can also move the first rotating shaft 32 back and forth within the moving cylinder 2, causing the positioning cylinder 31 to move back and forth, thus adjusting the position of the piercing element 7 in the front-back direction. By manually rotating the portion of the adjusting screw 36 located above the moving cylinder 2, adjusting the length of the adjusting screw 36 extending into the positioning hole 35, the first rotating shaft 32 can move up and down within the positioning hole 35, thereby causing the positioning cylinder 31 to rotate back and forth within the moving cylinder 2, thus adjusting the angle of the piercing element 7 in the front-back direction. The front-back direction is perpendicular to the left-right direction.

[0090] In this embodiment, by adjusting the screw 36, connecting ball 37, and rotating ball 38, the angle of the puncture member 7 can be adjusted in four horizontal directions (front, back, left, and right), and its position can be adjusted in the front-back direction. This further improves the adjustment flexibility of the puncture member 7 and enhances puncture accuracy. After the position and angle of the positioning cylinder 31 are adjusted, the limiting plug 33 is manually slidable to engage between the first rotating shaft 32 and the positioning hole 35, limiting the rotation and movement of the first rotating shaft 32 relative to the positioning hole 35. This fixes the angle and position of the positioning cylinder 31, thereby fixing the angle and position of the puncture member 7 and improving puncture stability.

[0091] In some embodiments, such as Figure 19As shown, the movable cylinder 2 includes three positioning holes 35 and three first rotating shafts 32. Two positioning holes 35 are located above the opening 21, and the third positioning hole 35 is located on the side of the movable cylinder 2 opposite to the switching component 5. Each first rotating shaft 32 passes through the positioning hole 35 and is connected to an adjusting bolt 36. The position of the positioning cylinder 31 can be adjusted by adjusting the position of any first rotating shaft 32, thereby adjusting the position of the puncture component 7. The arrangement of the three first rotating shafts 32 and the adjusting bolts 36 expands the position adjustment methods of the fixed cylinder 31 and improves the convenience of position adjustment. The three adjusting bolts 36 can also further improve the fixing stability of the positioning cylinder 31 and the puncture stability of the puncture component 7.

[0092] In some embodiments, alignment blocks 39 are provided on the outer surfaces of both ends of the first rotating shaft 32. The rotation angle of the first rotating shaft 32 relative to the positioning hole 35 can be determined by the position of the alignment blocks 39, which helps the first rotating shaft 32 to reset after puncture and improves the ease of use of the auxiliary puncture device.

[0093] In some embodiments, such as Figure 5 and Figure 11 As shown, the auxiliary puncture device also includes multiple second telescopic members 34. These second telescopic members 34 are evenly and spaced apart on the side of the positioning cylinder 31 away from the fixed cylinder 11. The fixed end of each second telescopic member 34 is connected to the positioning cylinder 31, and the telescopic end is detachably connected to the puncture member 7. By adjusting the telescopic length of the second telescopic members 34, the puncture depth of the puncture member 7 can be adjusted, making it suitable for different patients and expanding the working range of the auxiliary puncture device.

[0094] In this embodiment, the second telescopic member 34 can be a force-operated telescopic member, which shortens under pressure to assist the puncture device 7 in puncture, and remains stationary when no force is applied. A locking device is provided on the second telescopic member 34. When the locking device is closed, the extension and retraction of the second telescopic member 34 are unaffected; when the locking device is activated, the telescopic end will not move up or down even under pressure, reducing the probability of the puncture device 7 shaking or moving under force during subsequent fluid aspiration operations, thereby puncturing or scratching the patient's pleura, causing pain, and resulting in secondary injury, thus improving surgical safety. The type of locking device includes, but is not limited to, knob-type, snap-on, plate-type, and threaded types, and can be set according to actual needs.

[0095] In this embodiment, the telescopic end of the second telescopic member 34 and the puncture member 7 can be detachably connected to the puncture member 7 via a snap-fit ​​assembly, a magnetic attraction assembly, or an adhesive assembly. This ensures the stability of the connection between the telescopic end and the puncture member 7 without affecting subsequent needle removal operations. Specifically, the needle removal operation can be achieved by applying a pulling force to the puncture member 7 that is greater than the snap-fit ​​force between the snap-fit ​​assemblies, or greater than the magnetic attraction force between the magnetic attraction assemblies, or greater than the adhesive force between the adhesive assembly.

[0096] In this embodiment, the puncture device 7 includes a puncture tube and a puncture needle. The inner diameter of the puncture tube is larger than the outer diameter of the puncture needle, biopsy needle, and ablation needle. Subsequent aspiration and drug injection needles can all enter through the puncture tube, avoiding repeated punctures, preventing greater pain and harm to the patient, saving surgical time, and improving surgical efficiency.

[0097] In some embodiments, the auxiliary puncture device further includes a support frame disposed between the ground and the fixed cylinder 11 to support the fixed cylinder 11 and the movable cylinder 2, share the weight of the fixed cylinder 11 and the movable cylinder 2, avoid putting pressure on the patient, and improve the comfort of use.

[0098] In some embodiments, the auxiliary puncture device further includes a controller, which controls the opening, closing, opening duration, closing duration, and opening sequence of the inflation / deflation component 14 and the drive motor that drives the first telescopic component 42, the second rotating shaft 46, and the pressure cylinder 6, thereby improving the application intelligence and convenience of the auxiliary puncture device and enhancing the auxiliary puncture effect and efficiency.

[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
