Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a surgical device used in bronchoscopic surgery. Background Technology

[0002] Currently, bronchoscopy is one of the important diagnostic and treatment methods for respiratory diseases. It allows for direct visual observation of the trachea and bronchial lumens while performing biopsies to accurately diagnose diseases. Bronchoscopy can also be used to treat lung diseases, such as suctioning sputum, local hemostasis, and removal of neoplasms. Furthermore, it can be used for local drug administration to achieve better therapeutic effects.

[0003] Massive bleeding during bronchoscopy can often lead to asphyxiation and death.

[0004] Currently, the resuscitation of bleeding during bronchial examinations mainly relies on negative pressure suction through the bronchoscopic suction channel (the forceps channel of a conventional bronchoscope is approximately 2mm in diameter), lateral decubitus positioning, vasoconstrictors, and hemostatic agents. Under these current resuscitation measures, due to the small size of the bronchoscopic suction channel and the inability to perform timely endotracheal intubation, approximately 1 in 10,000 procedures results in death from massive hemorrhage and asphyxiation. With the development of bronchoscopic interventional therapy, the incidence of massive hemorrhage may be even higher. However, the current resuscitation efficiency for massive hemorrhage under bronchoscopy remains low.

[0005] Therefore, there is an urgent need to develop a device to prevent blood from entering the lungs during bronchoscopy when there is massive bleeding, in order to solve this problem. Summary of the Invention

[0006] The main objective of this invention is to provide a surgical device for bronchoscopy, which aims to solve the technical problem in the prior art that blood cannot be stopped from entering the lungs in time after massive bleeding during bronchoscopy.

[0007] To achieve the above objectives, the present invention proposes a surgical device for bronchoscopy, comprising a horizontally arranged operating table, with a tilting component and a lifting component arranged sequentially below the operating table for tilting the operating table, and a bronchoscopy auxiliary component arranged on one side of the operating table.

[0008] The tilting component includes a first arc plate recessed towards the side opposite to the operating table, an arc-shaped through hole formed in the first arc plate, a second arc plate slidably disposed in the through hole, both ends of the second arc plate extending out of the through hole, and both ends of the second arc plate being connected to the lower side of the operating table. The tilting component also includes a moving component for driving the second arc plate to slide within the through hole, and the lifting component is disposed on the side of the first arc plate opposite to the operating table.

[0009] The bronchoscopic surgical auxiliary components include a drainage assembly and a support assembly disposed on the side of the operating table to support the drainage assembly. The drainage assembly includes a catheter for inserting into the human trachea and a guide assembly for supporting and fixing the catheter. An expansion assembly is provided around the outer wall of one end of the catheter to abut against the inner wall of the human trachea.

[0010] Preferably, the moving component includes a motor disposed on the outer wall of the first arc plate, the output shaft of the motor being arranged laterally and connected to a first gear, a third arc-shaped groove being recessed on the side of the second arc plate near the first gear, the extension direction of the third arc-shaped groove being in the same direction as the extension direction of the second arc plate, a rack for meshing with the first gear being provided in the third arc-shaped groove, and a through hole being formed on the side of the first arc plate near the first gear for the first gear to extend into the through hole and mesh with the rack; the moving component also includes a positioning component for restricting the rotation of the first gear.

[0011] Preferably, the positioning component includes a first support plate laterally disposed on the side of the first arc plate near the operating table, and a connecting shaft disposed on the side of the first gear away from the motor. A second gear is provided at the end of the connecting shaft away from the first gear. A fixed arc plate is provided on the side of the first support plate near the second gear. A plurality of first protruding teeth for meshing with the second gear are provided on the side of the fixed arc plate near the second gear. A moving member is provided on the side of the first support plate near the first arc plate for driving the fixed arc plate to move toward or away from the second gear.

[0012] Preferably, the movable component includes two second support plates vertically arranged on the side of the first support plate near the first arc plate, a fixed arc plate located between the two second support plates, a connecting plate laterally connected to the side of the fixed arc plate near the second support plate, a support plate laterally connected to the side of each second support plate near the fixed arc plate, the support plate located above the connecting plate, an electric telescopic rod fixed to the second support plate on the side of the support plate away from the connecting plate, the output shaft of the electric telescopic rod vertically penetrating the support plate and connected to the connecting plate, a spring sleeved on the outer wall of the output shaft of the electric telescopic rod, the spring located between the support plate and the connecting plate.

[0013] Preferably, the support assembly includes a third support plate that is laterally disposed on one side of the operating table in the width direction. A lifting rod is slidably disposed above the third support plate, and the sliding direction of the lifting rod is in the same direction as the width direction of the operating table. A fourth support plate for supporting the drainage assembly is rotatably connected to the end of the lifting rod away from the third support plate.

[0014] Preferably, the operating table has two shoulder pillows that slide on the side of the operating table to abut against the human shoulder, and the sliding direction of the shoulder pillows is the same as the width direction of the operating table.

[0015] Preferably, the guiding assembly includes two fifth support plates vertically disposed on the side of the fourth support plate opposite to the lifting rod. Two third gears and two fourth gears are symmetrically rotatably disposed between the two fifth support plates. A first roller is connected between the two third gears, and a second roller is connected between the two fourth gears. The fourth gears are located above the third gears. The two third gears and the two fourth gears mesh with each other in a one-to-one correspondence. The outer wall of the first roller is recessed to form a first arc-shaped groove, and the outer wall of the second roller is recessed to form a second arc-shaped groove. The first arc-shaped groove and the second arc-shaped groove cooperate to form an annular receiving space for receiving the conduit. When the conduit is located in the annular receiving space, the outer wall of the conduit contacts the first arc-shaped groove and the second arc-shaped groove. The guiding assembly also includes a fixing assembly for realizing the rotation of the third gears and the fourth gears.

[0016] Preferably, the fixing assembly includes a rotating shaft that transversely passes through the fifth support plate and is connected to the third gear. The end of the rotating shaft opposite to the third gear is connected to the fifth gear. A receiving block is provided on one side of the fifth gear. A receiving hole is recessed on the side of the receiving block near the fifth gear. A push rod is slidably disposed in the receiving hole. The end of the push rod near the fifth gear extends out of the receiving hole and is connected to a locking block. A plurality of second protruding teeth that mesh with the fifth gear are distributed on the side of the locking block opposite to the receiving block. The cross-section of the push rod and the cross-section of the receiving hole are both rectangular. A screw is rotatably connected to the end of the push rod opposite to the locking block. The end of the screw opposite to the push rod passes through the side of the receiving block opposite to the locking block and is threadedly engaged with the receiving block.

[0017] Preferably, a receiving groove is formed around the outer wall of one end of the conduit, and the opening of the receiving groove is provided with a sealing layer for sealing the receiving groove. An annular airbag is sleeved inside the receiving groove. The airbag is connected to an air pump that can preset the inflation pressure through an air supply pipe. The air supply pipe is set inside the wall of the conduit, and a check valve is also connected to the air supply pipe.

[0018] Preferably, the drainage assembly further includes a lubricating element for lubricating the outer wall of the catheter. The lubricating element includes a horizontally arranged lubricating cylinder. The lubricating cylinder is connected to a fourth support plate via a support column at its lower end. A receiving cavity for containing lubricating fluid is formed in the cylinder wall on the side of the lubricating cylinder near the support column. An oil-absorbing layer is provided around the inner wall of the lubricating cylinder. The oil-absorbing layer extends into the receiving cavity through an oil-absorbing cotton strip that passes through the outer wall of the lubricating cylinder.

[0019] In the technical solution of this invention, since both the first and second arc plates are arc-shaped structures, when the moving component drives the second arc plate to slide within the through hole, the second arc plate can cause one side of the operating table to tilt towards the side closer to or away from the ground. When massive bleeding occurs in the bronchus during bronchoscopy, the moving component causes the operating table to tilt towards the side closer to the ground. At this time, the blood flowing out of the bronchus flows downward through the trachea under the action of gravity, preventing blood from flowing into the lungs. The drainage component is used to guide the blood outflow and prevent blood from flowing into the nasal cavity. Through the cooperation between the above structures, it is possible to prevent blood from flowing into the lungs and causing suffocation when massive bleeding occurs in the bronchus.

[0040] This invention proposes a surgical device for bronchoscopic surgery.

[0041] Please refer to Figures 1 to 11 The surgical device used in bronchoscopy includes a horizontally arranged operating table 1. Below the operating table 1, there are tilting components 2 and lifting components 4 for tilting the operating table 1. A bronchoscopy auxiliary component 3 is provided on one side of the operating table 1.

[0042] The tilting component 2 includes a first arc plate 21 recessed on the side opposite to the operating table 1. An arc-shaped through hole 21a is formed in the first arc plate 21. A second arc plate 22 is slidably disposed in the through hole 21a. Both ends of the second arc plate 22 extend out of the through hole 21a. Both ends of the second arc plate 22 are respectively connected to the lower side of the operating table 1. The tilting component 2 also includes a moving component 23 for driving the second arc plate 22 to slide in the through hole 21a. The lifting component 4 is disposed on the side of the first arc plate 21 opposite to the operating table 1.

[0043] The bronchoscopic surgery auxiliary component 3 includes a drainage component 32 and a support component 31 disposed on the side of the operating table 1 for supporting the drainage component 32. The drainage component 32 includes a catheter 321 for inserting into the human trachea 8 and a guide component 322 for supporting and fixing the catheter 321. An expansion component for contacting the inner wall of the human trachea 8 is provided around the outer wall of one end of the catheter 321.

[0044] In the technical solution of the present invention, since both the first arc plate 21 and the second arc plate 22 are arc-shaped structures, when the moving component 23 drives the second arc plate 22 to slide within the through hole 21a, the second arc plate 22 can cause one side of the operating table plate 1 to tilt towards the side closer to the ground or away from the ground. When massive bleeding occurs in the bronchus 8 during bronchoscopy, the moving component 23 drives the operating table plate 1 to tilt towards the side closer to the ground. At this time, the blood flowing out of the bronchus 8 flows downward through the trachea 8 under the action of gravity to prevent blood from flowing into the lungs. The drainage component 32 is used to guide the blood out and prevent blood from flowing into the nasal cavity. Through the cooperation between the above structures, it is possible to prevent blood from flowing into the lungs and causing suffocation when massive bleeding occurs in the bronchus 8.

[0045] Please refer to the appendix. Figure 2-3 The moving component 23 includes a motor 231 disposed on the outer wall of the first arc plate 21. The output shaft of the motor 231 is arranged laterally and connected to a first gear 232. A third arc groove 22a is recessed on the side of the second arc plate 22 near the first gear 232. The extension direction of the third arc groove 22a is the same as the extension direction of the second arc plate 22. A rack 233 for meshing with the first gear 232 is provided in the third arc groove 22a. A through hole 21b is formed on the side of the first arc plate 21 near the first gear 232, allowing the first gear 232 to extend into the through hole 21a and mesh with the rack 233. The moving component 23 also includes a positioning component 24 for restricting the rotation of the first gear 232. The motor 231 drives the first gear 232 to rotate, causing the first gear 232 and the rack 233 to mesh with each other, which in turn drives the second arc plate 22 to slide within the through hole 21a. As the second arc plate 22 slides, it causes the operating table plate 1 to tilt towards the side closer to or away from the ground. Before the patient lies on the operating table plate 1 for bronchoscopy, the motor 231 drives the operating table plate 1 to rotate, so that the patient, who was originally lying horizontally, is in a tilted position with their head down and feet up when the operating table plate 1 is tilted. The tilt angle can be set as needed. Thus, if the bronchus 8 is ruptured and bleeding occurs during the operation, the blood will flow out of the trachea 8 under the action of gravity because the operating table plate 1 is tilted towards the side closer to the ground, preventing the blood from flowing into the lungs through the bronchus 8.

[0046] Please refer to the appendix. Figure 1 and3 -4, the positioning component 24 includes a first support plate 234 laterally disposed on the side of the first arc plate 21 near the operating table plate 1, and a connecting shaft 244 disposed on the side of the first gear 232 away from the motor 231. The end of the connecting shaft 244 away from the first gear 232 is provided with a second gear 241. The side of the first support plate 234 near the second gear 241 is provided with a fixed arc plate 242. The side of the fixed arc plate 242 near the second gear 241 is provided with a plurality of first protruding teeth 243 for meshing with the second gear 241. The side of the first support plate 234 near the first arc plate 21 is provided with a moving member 244 for driving the fixed arc plate 242 to move toward or away from the second gear 241. The moving part 244 drives the fixed arc plate 242 to move towards the side closer to the second gear 241, so that the tooth grooves between the multiple first protrusions 243 mesh with the second gear 241. When the second gear 241 and the first protrusions 243 mesh with each other, the second gear 241 cannot rotate. When the second gear 241 cannot rotate, the first gear 232 also cannot rotate, thereby realizing the positioning of the tilting and scheduling of the operating table plate 1.

[0047] Please refer to the appendix. Figure 4 The movable component 244 includes two second support plates 2445 vertically arranged on the side of the first support plate 234 near the first arc plate 21. The fixed arc plate 242 is located between the two second support plates 2445. A connecting plate 2441 is laterally connected to the side of the fixed arc plate 242 near the second support plate 2445. A support plate 2442 is laterally connected to the side of each second support plate 2445 near the fixed arc plate 242. The support plate 2442 is located on the upper side of the connecting plate 2441. An electric telescopic rod 2443 is fixed on the second support plate 2445 on the side of the support plate 2442 away from the connecting plate 2441. The output shaft of the electric telescopic rod 2443 vertically passes through the support plate 2442 and is connected to the connecting plate 2441. A spring 2444 is sleeved on the outer wall of the output shaft of the electric telescopic rod 2443. The spring 2444 is located between the support plate 2442 and the connecting plate 2441. When the second gear 241 rotates, the electric telescopic rod 2443 drives the connecting plate 2441 to move towards the side closer to the support plate 2442, causing the fixed arc plate 242 to move away from the second gear 241. When the second gear 241 is fixed, the electric telescopic rod 2443 is de-energized, causing the spring 2444 to release its elastic potential energy, which drives the fixed arc plate 242 to move towards the side closer to the second gear 241, so that the multiple first protrusions 243 mesh with the second gear 241 to limit the rotation of the second gear 241. Furthermore, it can also ensure that even if the power is cut off when the device is in use, the operating table plate 1 will not tilt, thereby improving the safety of use.

[0048] Please refer to the appendix. Figure 10 The support assembly 31 includes a third support plate 311 laterally disposed on one side of the operating table 1 in the width direction. A lifting rod 312 is slidably disposed above the third support plate 311, and the sliding direction of the lifting rod 312 is in the same direction as the width direction of the operating table 1. A fourth support plate 313 for supporting the drainage assembly 32 is rotatably connected to the end of the lifting rod 312 opposite to the third support plate 311. The lifting rod 312 is used to adjust the height of the drainage assembly 32, thereby adjusting the height of the catheter 321. The fourth support plate 313 is rotatably connected to the lifting rod 312 to adjust the direction of the catheter 321. The two sides of the inclined operating table 1 are in the width direction of the operating table 1.

[0049] Please refer to the appendix. Figure 10 The operating table 1 has two slidable shoulder pillows 33 on its upper side for contacting the shoulders of the human body. The sliding direction of the shoulder pillows 33 is the same as the width direction of the operating table 1. The human head is placed between the two shoulder pillows 33, and the position of the shoulder pillows 33 is adjusted so that they contact the human shoulders. As one side of the operating table 1 tilts towards the ground, the human body tilts along with the operating table 1, and the shoulders contact the shoulder pillows 33. This prevents the human body from slipping off the operating table 1 when it tilts.

[0050] Please refer to the appendix. Figure 5-6The guiding assembly 322 includes two fifth support plates 3225 vertically arranged on the side of the fourth support plate 313 opposite to the lifting rod 312. Two third gears 3221 and two fourth gears 3222 are symmetrically rotatably arranged between the two fifth support plates 3225. A first roller 3223 is connected between the two third gears 3221, and a second roller 3224 is connected between the two fourth gears 3222. The fourth gears 3222 are located above the third gears 3221. The two third gears 3221 and the two fourth gears 3222 mesh with each other in a one-to-one correspondence. The first roller 3223... The outer wall of the 23 is recessed to form a first arc-shaped groove 3223a, and the outer wall of the second roller 3224 is recessed to form a second arc-shaped groove 3224a. The first arc-shaped groove 3223a and the second arc-shaped groove 3224a cooperate to form an annular receiving space for receiving the conduit 321. When the conduit 321 is located in the annular receiving space, the outer wall of the conduit 321 contacts the first arc-shaped groove 3223a and the second arc-shaped groove 3224a. The guide assembly 322 also includes a fixing assembly 323 for realizing the rotation of the third gear 3221 and the fourth gear 3222. The conduit 321 is made of silicone. Silicone layers are respectively provided on the groove walls of the first arc-shaped groove 3223a and the groove walls of the second arc-shaped groove 3224a to increase the friction between the outer wall of the conduit 321 and the first arc-shaped groove 3223a and the second arc-shaped groove 3224a. This enables the conduit 321 to move when the third gear 3221 and the fourth gear 3222 are meshing and rotating, and prevents the conduit 321 from moving when the third gear 3221 and the fourth gear 3222 are not rotating.

[0051] Please refer to the appendix. Figure 5 and 7The fixing component 323 includes a rotating shaft 3231 that extends laterally through the fifth support plate 3225 and is connected to the third gear 3221. The end of the rotating shaft 3231 facing away from the third gear 3221 is connected to the fifth gear 3232. A receiving block 3233 is provided on one side of the fifth gear 3232. A receiving hole 3233a is recessed on the side of the receiving block 3233 near the fifth gear 3232. A push rod 3234 is slidably disposed within the receiving hole 3233a, with the end of the push rod 3234 near the fifth gear 3232 extending outwards. The receiving hole 3233a is connected to a locking block 3235. The locking block 3235 has multiple second protruding teeth 3236 that mesh with the fifth gear 3232 on the side opposite to the receiving block 3233. The cross-section of the push rod 3234 and the cross-section of the receiving hole 3233a are both rectangular. The end of the push rod 3234 opposite to the locking block 3235 is rotatably connected to a screw 3237. The end of the screw 3237 opposite to the push rod 3234 passes through the side of the receiving block 3233 opposite to the locking block 3235 and is threadedly engaged with the receiving block 3233. By rotating the screw 3237, the push rod 3234 is moved toward or away from the fifth gear 3232. When the push rod 3234 moves toward the fifth gear 3232, the grooves of the multiple second protrusions 3236 on the locking block 3235 can mesh with the fifth gear 3232 to prevent the fifth gear 3232 from rotating. The inability of the fifth gear 3232 to rotate thus restricts the rotation of the third gear 3221. Conversely, the fifth gear 3232 and the third gear 3221 can rotate.

[0052] Please refer to the appendix. Figure 9 and 11 The outer wall of one end of the conduit 321 is surrounded by a receiving groove 321a. The opening of the receiving groove 321a is provided with a sealing layer 5 for sealing the receiving groove 321a. An annular airbag 6 is sleeved inside the receiving groove 321a. The airbag is connected to an air pump that can preset the inflation pressure through an air supply pipe 87. The air supply pipe 87 is located inside the wall of the conduit 321 and is also connected to a check valve. The air pump inflates the annular airbag 6 through the air supply pipe 87, causing the annular airbag 6 to expand in volume, thereby allowing the conduit 321 to be fixed inside the air tube 8. At the same time, the annular airbag 6 can fit tightly against the air tube 8. The air pump can detect the air pressure of the annular airbag 6 in real time, so that when the conduit 321 is located inside the air tube 8, it can prevent the annular airbag 6 from being over-inflated and squeezed by the air tube 8, which could cause damage to the air tube 8.

[0053] Please refer to the appendix. Figure 8The drainage assembly 32 further includes a lubricating element 324 for lubricating the outer wall of the conduit 321. The lubricating element 324 includes a horizontally arranged lubricating cylinder 3241. The lubricating cylinder 3241 is connected to the fourth support plate 313 via a support column 3243 at its lower end. A receiving cavity 3241a for receiving lubricating fluid is formed in the cylinder wall of the lubricating cylinder 3241 near the support column 3243. An oil-absorbing layer 3242 is arranged around the inner wall of the lubricating cylinder 3241. The oil-absorbing layer 3242 extends into the receiving cavity 3241a through an oil-absorbing cotton strip 3244 penetrating the outer wall of the lubricating cylinder 3241. The oil-absorbing cotton strip 3244 allows the lubricating fluid in the receiving cavity 3241a to be transferred to the oil-absorbing layer 3242, which absorbs the lubricating fluid. When in use, the conduit 321 passes through the lubrication cylinder 3241, causing the oil-absorbing layer 3242 to come into contact with the outer wall of the conduit 321, so that the outer wall of the conduit 321 is contaminated with lubricating fluid, so that the conduit 321 can enter the trachea 8.

[0054] Furthermore, the surgical device also includes a control system, which is signal-connected to a detection component for detecting bleeding under bronchoscopy and to a motor 231. The control system controls the rotation of the output shaft of motor 231 based on the bleeding detected by the detection component, adjusting the patient's posture in a timely manner to prevent blood from flowing into the lungs. The detection component can be a miniature lens.
