A novel tracheotomy sealing device

Abstract

This invention relates to the field of medical devices, and particularly to a novel tracheostomy occlusion device, comprising an operating table, a fixation plate, an adjustment mechanism, and an execution mechanism. This invention addresses the following problems encountered in the practical use of tracheostomy auxiliary retraction devices: prolonged holding of the retractor by the surgical assistant can cause soreness and lead to shaking of the retractor, which in turn can cause neck movement, affecting the normal progress of the surgery and potentially causing further trauma to the patient's trachea. Furthermore, it cannot effectively manage blood flowing from the neck, which may lead to blood entering the trachea and causing respiratory discomfort, even threatening the patient's life; the portion of the tracheostomy cannula inside the trachea obstructs the airway, affecting the patient's ability to cough up sputum and leading to inaccurate assessments of the patient's coughing ability; and it can easily cause blind sinus tracts to form at the tracheostomy site.

Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a novel tracheotomy occlusion device. Background Technology

[0002] Tracheotomy is a surgical procedure in which the anterior wall of the cervical trachea is cut open to create a new passage for breathing. It is mainly used to rescue patients with laryngeal obstruction to relieve respiratory distress caused by laryngeal dyspnea, respiratory dysfunction, or lower respiratory tract secretion retention. After the surgery, a tube is inserted into the trachea and then the area around the tube in front of the trachea is sealed.

[0003] In current clinical practice, for patients with tracheostomies, if the conditions for tube sealing and extubation are met, the following two methods are commonly used for extubation: 1. Loosen the tracheostomy tube cuff and partially seal the tube with adhesive tape. If the patient's oxygen saturation is stable, then fully seal the tube using adhesive tape or by opening the inner core of the tracheostomy tube. If the patient can cough normally and the oxygen saturation is stable, then extubate the tube and use butterfly-shaped adhesive tape to seal the wound skin; 2. Loosen the tracheostomy tube cuff. If the oxygen saturation is stable, extubate the tube directly and use butterfly-shaped adhesive tape to seal the wound skin.

[0004] However, problems have been found in the above extubation method in clinical practice: 1. The part of the tracheostomy tube inside the trachea obstructs the airway, affects the patient's cough, and leads to errors in assessing the patient's cough ability, prolonging the tube-in-wear time or overestimating the patient's cough ability; in addition, it can easily lead to the formation of blind tube sinus tracts for skin healing at the tracheostomy site.

[0005] In addition, during the tracheotomy, the skin tissue of the patient's neck is first cut to form an incision. During this process, bleeding points in the skin tissue are stopped by electrocoagulation. Then, two nurses or surgical assistants hold retractors and pull them to the left and right to tear open the outer skin tissue of the anterior wall of the patient's neck, so that the doctor can cut the patient's trachea. However, the two retractors have the problem of uneven pulling force and are inconvenient to adjust. At the same time, the traction direction and angle of the retractors can easily change at will, which affects the normal progress of the tracheotomy.

[0006] To address the aforementioned issues, those skilled in the art have optimized the retractor used for tracheotomy. For a more accurate comparison, Chinese Patent No. CN113559377A discloses a tracheotomy auxiliary retraction device that is easy to operate with one hand, including a hand-held retraction assembly, which includes a hand handle, a fixed end and a movable end located at the front end of the hand handle; and a retractor assembly, which includes a retractor portion that is movably hinged to the ends of the fixed end and the movable end.

[0007] When using it, after the surgeon completes the incision, the surgical assistant places the hook part of the retraction device, which has a closed fixed end and a movable end, at the incision. At the same time, the distance between the movable end and the fixed end is slowly adjusted according to the incision. The incision is then retracted when it is adjusted to a suitable size. Meanwhile, in order to ensure the surgical field of vision, the angle of the hook part can be adjusted appropriately. Then the surgical assistant holds the handle.

[0008] However, the aforementioned tracheotomy-assisted retraction device still has some shortcomings in actual use:

[0009] 1. Because the incision needs to be kept open for a long time, the surgical assistant's arm needs to remain still for a long time. This can easily lead to soreness in the arm, causing the retractor to shake. As a result, it is impossible to ensure that both sides of the incision remain fixed. Furthermore, the shaking of the retractor can easily cause the patient's neck to shake, thus affecting the normal progress of the surgery and potentially causing additional trauma to the patient's trachea.

[0010] 2. In addition, after the surgeon cuts open the outer skin of the anterior cervical wall, although the bleeding point can be stopped by electrocoagulation, there will still be residual blood in the patient's neck, and the blood will accumulate at the incision site. The existing technology mentioned above cannot deal with the blood flowing out of the neck. Therefore, when the surgeon cuts open the trachea, blood may flow into the trachea, causing the patient to have difficulty breathing. Moreover, blood can easily flow into the lungs through the trachea, threatening the patient's life.

[0011] Therefore, based on the above-mentioned viewpoints, there is still room for improvement in existing tracheotomy and occlusion techniques. Summary of the Invention

[0012] To address the aforementioned problems, this invention provides a novel tracheotomy occlusion device, comprising an operating table, with fixing plates installed on both side walls of the operating table in the width direction. The fixing plates are located on the side of the operating table closer to the patient's head.

[0016] Preferably, the fixing plate has an installation groove inside, and a first bevel gear is rotatably connected to the outer wall of the self-locking screw in the installation groove. The fixing plate also has a connecting groove arranged perpendicular to the installation groove. A second bevel gear that meshes with the first bevel gear is rotatably connected in the connecting groove. A rotating shaft is installed on the side of the second bevel gear away from the self-locking screw. The end of the rotating shaft away from the second bevel gear passes through the fixing plate and is connected to a turntable.

[0017] Preferably, the lateral adjustment assembly includes a positioning plate mounted on the upper end of the fixed plate, a V-shaped frame mounted on the side of the positioning plate near the horizontal plate, a V-shaped guide groove provided on the side of the V-shaped frame near the horizontal plate, and a positioning pin slidably connected in the V-shaped guide groove mounted on the side of the horizontal plate opposite to the V-shaped frame.

[0018] Preferably, both the V-shaped frame and the V-shaped guide groove are composed of two extension sections and a curved section in the middle, and the middle part of the V-shaped frame is a corrugated structure that is easy to bend. The V-shaped guide groove can deform accordingly with the V-shaped frame to adjust the angle between the two extension sections of the V-shaped guide groove.

[0019] The upper and lower sides of the positioning plate are provided with arc-shaped through holes centered on the curved section of the V-shaped frame. Multiple annularly distributed limiting holes are provided on the side of the arc-shaped through holes away from the V-shaped frame. An adjustment plate is installed on the side of the lower extension of the V-shaped frame away from the horizontal plate via a telescopic rod. A plug pin is installed on the side of the adjustment plate close to the positioning plate and is movably inserted into the limiting hole.

[0020] Preferably, the blood processing assembly further includes a receiving cavity opened inside the extension plate, an outlet pipe extending into the receiving cavity is installed at the output end of the water pump, multiple inlet holes are evenly opened through the outer wall of the arc-shaped cylinder, and an inlet pipe extending into the arc-shaped cylinder after passing through the extension plate and the actuating plate is installed at the input end of the water pump.

[0021] Preferably, the two ends of the arc-shaped cylinder are telescopic structures that facilitate length adjustment. The arc-shaped cylinder and the actuating plate are detachably mounted with flexible extrusion pads on the side near the horizontal plate, and both ends of the arc-shaped cylinder are equipped with support blocks connected to the flexible extrusion pads.

[0022] Preferably, it also includes a sealing sleeve for sealing the trachea, the sealing sleeve including a sealing inner core cap, a sealing tube being detachably installed at the end of the sealing inner core cap, and a sealing tube core being installed at the end of the sealing inner core cap near the sealing tube, and a fixing wing being provided on the outer wall of the sealing tube near the sealing inner core cap.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] I. This invention rotates a self-locking screw, which drives the lifting block, linkage plate, retraction spring rod, horizontal plate, and actuator to move downwards, so that the actuator is close to both sides of the incision in the patient's neck. This allows the actuators on both sides of the operating table to move up and down synchronously, thereby improving the efficiency of adjusting the actuator and making the operation convenient.

[0025] Second, this invention, through the cooperation of the horizontal plate, positioning pin, V-shaped frame and V-shaped guide groove, can control the actuator to tilt towards the side closer to the operating table during its downward movement; then, it controls the actuator to move away from the operating table during its downward movement and pulls the already cut skin tissue of the patient's neck to both sides; the operation is simple and does not require manual operation, so as to improve the stability of the actuator when pulling the skin tissue, thereby preventing the patient's neck from shaking randomly under external force and affecting the accuracy of the doctor's tracheotomy.

[0026] Third, by adjusting the tilt angle of the V-shaped frame extension section, the present invention can control the relative increase or decrease of the distance the actuating plate moves towards or away from the operating table during its downward movement. Furthermore, it can be adjusted according to the diameter of the patient's neck, thereby adapting to patients of different body types and improving the adaptability of the present invention.

[0027] Fourth, this invention uses a lever and an arc-shaped cylinder to apply pressure to the cut skin tissue to stop bleeding, thereby preventing prolonged bleeding from the patient's neck. Furthermore, neither the lever nor the arc-shaped cylinder moves arbitrarily during the procedure, ensuring the incision on the patient's neck remains fixed and preventing uncontrolled neck movement. The flexible pressure pad conforms to the incision on the patient's neck, resulting in better hemostasis. Additionally, the length of the arc-shaped cylinder can be adjusted according to the length of the incision, and it can simultaneously stretch or contract the flexible pressure pad, facilitating pressure hemostasis for incisions of different lengths.

[0028] Fifth, this invention uses a water pump to extract blood flowing into the arc-shaped cylinder, thereby promptly clearing blood from the patient's neck and preventing blood from flowing into the trachea during tracheotomy, which could cause breathing discomfort to the patient and thus improve the safety of the surgical procedure.

[0029] VI. This invention can increase the patency of the patient's trachea by sealing the cannula, and accurately observe and assess the patient's coughing ability; by changing the sealing cannula with different outer diameters, it can promote the gradual and synchronous healing of the incision skin and subcutaneous tissue, and avoid the formation of subcutaneous blind tube sinus tracts; if the patient experiences respiratory distress during the sealing process, it can be quickly replaced with a conventional tracheostomy cannula for artificial ventilation.

Detailed Implementation

[0040] The following is in conjunction with the appendix Figures 1-8 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.

[0041] This application discloses a novel tracheotomy occlusion device. Specifically, this novel tracheotomy occlusion device is mainly used during tracheotomy surgery. Technically, it can apply pressure to stop bleeding from the cut skin tissue and pull the cut skin tissue on both sides of the patient's neck. During the surgery, it ensures that the patient's neck remains fixed, preventing random neck movement. Especially when stopping bleeding at the neck incision, it can promptly remove blood from the patient's neck, preventing blood from flowing into the trachea and causing breathing discomfort. Furthermore, this novel tracheotomy occlusion device can control the distance the actuator 4 moves towards or away from the operating table 1 during downward movement, thus adapting to patients of different body types.

[0042] Example 1:

[0043] Reference Figure 1 As shown, a novel tracheotomy occlusion device includes an operating table 1. Fixing plates 2 are installed on both sides of the operating table 1 in the width direction. The fixing plates 2 are located on the side of the operating table 1 closer to the patient's head. An adjustment mechanism 3 is installed on the upper end of the fixing plates 2. The adjustment mechanism 3 includes a horizontal plate 31 located above the fixing plates 2. An execution mechanism 4 is provided on the horizontal plate 31.

[0044] In practical application, the patient first lies on the operating table 1, with the patient's neck positioned between the two actuators 4; then the doctor cuts the skin tissue of the anterior wall of the patient's neck, and then adjusts the actuators 4 accordingly through the adjustment mechanism 3, so that the actuators 4 pull the skin tissue of the anterior wall of the patient's neck to both sides, so that the doctor can cut the patient's trachea.

[0045] Reference Figure 1 and Figure 2 As shown, the adjustment mechanism 3 also includes a linkage plate 32. The linkage plate 32 is installed above the fixed plate 2 and on the side of the horizontal plate 31 away from the operating table 1. Multiple retraction spring rods 33 are evenly spaced along the width direction between the linkage plate 32 and the horizontal plate 31 on the same side of the operating table 1. The retraction spring rods 33 always apply a retraction force to the horizontal plate 31 pointing towards the linkage plate 32, so that the distance between the horizontal plate 31 and the linkage plate 32 is minimized in the initial state. Two fixed blocks 311 are installed on the upper and lower side walls of the horizontal plate 31 along its width direction. Multiple support columns 321 that slide through the fixed blocks 311 are installed on the side of the linkage plate 32 near the horizontal plate 31. A longitudinal adjustment component 34 is installed between the linkage plate 32 and the fixed plate 2, and a transverse adjustment component 35 is provided between the horizontal plate 31 and the fixed plate 2.

[0046] It should be noted that the cooperation between the fixing block 311 and the support column 321 can apply a supporting force to the horizontal plate 31, preventing the horizontal plate 31 from tilting downwards under the action, so that the horizontal plate 31 always remains in a horizontal state.

[0047] In the specific working process, the vertical adjustment component 34 controls the overall lifting and lowering of the linkage plate 32, the retraction spring rod 33 and the horizontal plate 31, so that the horizontal plate 31 can drive the actuator 4 to move to the skin tissue that has been cut on the patient's neck; then the horizontal adjustment component 35 drives the actuator 4 to pull the skin tissue to both sides.

[0048] Reference Figure 2 and Figure 3 As shown, the longitudinal adjustment component 34 includes a self-locking screw 341. The self-locking screw 341 is rotatably connected to the fixed plate 2. The lower end of the self-locking screw 341 passes through the fixed plate 2, and the two self-locking screws 341 are connected by a belt drive. A lifting block 342 is provided on the side of the linkage plate 32 away from the retraction spring rod 33. The self-locking screw 341 passes through the lifting block 342 by a threaded connection. Two guide posts 343 are symmetrically arranged on the upper end of the fixed plate 2 along the self-locking screw 341, which slide through the lifting block 342. The guide posts 343 can limit the lifting block 342. When the self-locking screw 341 rotates, the lifting block 342 can only move up and down and will not rotate with the self-locking screw 341.

[0049] Furthermore, in this embodiment, an installation groove is provided inside the fixing plate 2, and a first bevel gear 344 is rotatably connected to the outer wall of the self-locking screw 341. A connecting groove is also provided inside the fixing plate 2, which is perpendicular to the installation groove. A second bevel gear 345 that meshes with the first bevel gear 344 is rotatably connected in the connecting groove. A rotating shaft 346 is installed on the side of the second bevel gear 345 away from the self-locking screw 341. The end of the rotating shaft 346 away from the second bevel gear 345 passes through the fixing plate 2 and is connected to a turntable 347.

[0050] In the initial state, the lifting block 342, the linkage plate 32, the horizontal plate 31, and the actuator 4 are all in the highest position, so as not to obstruct the patient lying on the operating table 1.

[0051] In the specific operation, after the skin tissue of the anterior cervical wall of the patient is cut, any one of the turntables 347 is rotated. The turntable 347 drives the second bevel gear 345 to rotate through the rotating shaft 346. The second bevel gear 345 drives the self-locking screw 341 to rotate through the first bevel gear 344. The self-locking screw 341 drives the other self-locking screw 341 to rotate synchronously through the belt drive. The self-locking screw 341 drives the linkage plate 32, the retraction spring rod 33, the horizontal plate 31 and the actuator 4 to move downward through the lifting block 342, so that the actuator 4 is close to both sides of the incision in the patient's neck. In this way, the actuators 4 on both sides of the operating table 1 can be controlled to move up and down synchronously, thereby improving the efficiency of adjusting the actuator 4 and making the operation convenient.

[0052] After the surgery is completed, the turntable 347 is rotated in the opposite direction. Through the cooperation between the turntable 347, the first bevel gear 344, the second bevel gear 345 and the self-locking screw 341, the lifting block 342, the linkage plate 32, the horizontal plate 31 and the actuator 4 can be moved upward as a whole, thereby removing the actuator 4 from the incision in the patient's neck.

[0053] It should be noted that in this embodiment, the self-locking screw 341 can lock itself after rotating a certain angle, so that it will not rotate arbitrarily, thereby limiting the lifting block 342, and further limiting the linkage plate 32, the horizontal plate 31 and the actuator 4 longitudinally, so as to prevent them from moving up and down arbitrarily and causing the actuator 4 to be unable to fit with the cut skin tissue.

[0054] Reference Figure 4 , Figure 5 and Figure 6As shown, the lateral adjustment assembly 35 includes a positioning plate 351 mounted on the upper end of the fixed plate 2. A V-shaped frame 352 is mounted on the side of the positioning plate 351 near the horizontal plate 31. A V-shaped guide groove 353 is provided on the side of the V-shaped frame 352 near the horizontal plate 31. Both the V-shaped frame 352 and the V-shaped guide groove 353 are composed of two extension sections and a curved section in the middle. A positioning pin 354 is mounted on the side of the horizontal plate 31 relative to the V-shaped frame 352 and is slidably connected in the V-shaped guide groove 353.

[0055] In the specific implementation process, as the horizontal plate 31 drives the actuator 4 to move downward, the horizontal plate 31, through the cooperation between the positioning pin 354 and the V-shaped guide groove 353, causes the positioning pin 354 to move along the upper extension of the V-shaped guide groove 353. The horizontal plate 31 drives the actuator 4 to move towards the side closer to the middle of the operating table 1, thereby controlling the actuator 4 to tilt towards the side closer to the operating table 1 during the downward movement, so that both actuators 4 are close to the sides of the patient's already cut skin tissue.

[0056] Subsequently, the horizontal plate 31 drives the actuator 4 to continue moving downward. At this time, the positioning pin 354 moves along the extension of the lower side of the V-shaped guide groove 353, so that the horizontal plate 31 drives the actuator 4 to move away from the operating table 1 during the downward movement. Thus, the actuator 4 can pull the skin tissue that has been cut in the patient's neck to both sides. The operation is simple and does not require manual operation, which improves the stability of the actuator 4 when pulling the skin tissue, thereby preventing the patient's neck from shaking randomly under the action of external force and affecting the accuracy of the doctor's tracheotomy.

[0057] Continue to refer to Figure 4 and Figure 6 As shown, the middle part of the V-shaped frame 352 is a corrugated structure that is easy to bend. The V-shaped guide groove 353 can deform accordingly with the V-shaped frame 352 to adjust the angle between the two extension sections of the V-shaped guide groove 353. The upper and lower sides of the positioning plate 351 are provided with arc-shaped through holes 355 with the curved section of the V-shaped frame 352 as the center. On the side of the arc-shaped through hole 355 away from the V-shaped frame 352, a plurality of annularly distributed limiting holes 356 are evenly provided. On the side of the lower extension section of the V-shaped frame 352 away from the horizontal plate 31, an adjusting plate 357 is installed by a telescopic rod. On the side of the adjusting plate 357 close to the positioning plate 351, a plug pin 358 is installed that is movably inserted into the limiting hole 356.

[0058] In this embodiment, since patients of different body types have different neck diameters, the incision height of the patient's neck also varies; when the patient's neck diameter is larger, the neck incision height is relatively larger; conversely, when the patient's neck diameter is smaller, the neck incision height is relatively smaller. Therefore, it is necessary to adjust the diameter of the extension section of the V-frame 352 according to the diameter of the patient's neck, so as to control the distance that the actuator 4 moves towards the side closer to the operating table 1 while moving downwards by the same distance. The specific operation steps are as follows:

[0059] Adjusting plate 357 can rotate the upper and lower extensions of V-frame 352 along the arc-shaped through hole 355. Then, adjusting plate 357 drives the insertion pin 358 into the limiting hole 356 to fix the lower extension of V-frame 352. When the extension of V-frame 352 tilts towards the operating table 1, the distance the horizontal plate 31 and actuator 4 move towards or away from the operating table 1 during downward movement is relatively reduced, which is suitable for patients with larger neck diameters. Conversely, when the extension of V-frame 352 tilts away from the operating table 1, the distance the horizontal plate 31 and actuator 4 move towards or away from the operating table 1 during downward movement is relatively increased (the adjustment states of the upper and lower extensions of V-frame 352 are as follows). Figure 6 As shown), this is suitable for patients with a smaller neck diameter; thus, it can be adapted to patients of different body types, thereby improving the adaptability of the invention.

[0060] Reference Figure 7 As shown, the actuator 4 includes an extension plate 41. The extension plate 41 is installed on the side of the horizontal plate 31 near the middle of the operating table 1. A toggle plate 42 is provided at the bottom of the extension plate 41 on the side away from the horizontal plate 31. An arc-shaped cylinder 43 is installed at the lower end of the toggle plate 42. A blood processing assembly 44 is installed between the extension plate 41, the toggle plate 42 and the arc-shaped cylinder 43. The blood processing assembly 44 includes a water pump 441 installed at the upper end of the horizontal plate 31.

[0061] Furthermore, in this embodiment, the two ends of the arc-shaped cylinder 43 are telescopic structures that facilitate length adjustment. The arc-shaped cylinder 43 and the actuating plate 42 are detachably mounted with a flexible compression pad 446 on the side near the horizontal plate 31. Both ends of the arc-shaped cylinder 43 are equipped with support blocks 447 connected to the flexible compression pad 446.

[0062] It should be noted that although electrocoagulation can be used to stop bleeding at the point of bleeding in the patient's neck, bleeding may still occur when the incision in the patient's neck is pulled to both sides. Therefore, it is necessary to perform appropriate hemostasis on the already cut skin tissue.

[0063] In the specific implementation process, the horizontal plate 31 moves synchronously with the extension plate 41 and the actuating plate 42. When the actuating plate 42 is located at the incision site on the patient's neck, both the actuating plate 42 and the arc-shaped cylinder 43 drive the flexible compression pad 446 to press and stop the bleeding of the already cut skin tissue, thereby avoiding prolonged bleeding from the patient's neck. Furthermore, the actuating plate 42 and the arc-shaped cylinder 43 will not shake arbitrarily during the operation, thus ensuring that the incision on the patient's neck remains fixed and preventing the patient's neck from moving arbitrarily. Since the flexible compression pad 446 is easily deformable, it can fit snugly against the incision on the patient's neck, thereby achieving a better hemostatic effect. After the operation is completed, the flexible compression pad 446 can be replaced.

[0064] In addition, the length of the arc-shaped cylinder 43 can be adjusted according to the length of the incision in the patient's neck, and the arc-shaped cylinder 43 can simultaneously stretch or contract the flexible compression pad 446, thereby facilitating hemostasis by applying pressure to incisions of different lengths.

[0065] Continue to refer to Figure 7 As shown, the blood processing assembly 44 also includes a receiving cavity 442 opened inside the extension plate 41, an outlet pipe 443 extending into the receiving cavity 442 is installed at the output end of the water pump 441, a plurality of liquid inlet holes 444 are evenly opened through the outer wall of the arc-shaped cylinder 43, and an inlet pipe 445 is installed at the input end of the water pump 441 after passing through the extension plate 41 and the actuating plate 42 and extending into the arc-shaped cylinder 43.

[0066] During the specific implementation process, as the flexible compression pad 446 presses against the incision in the patient's neck to stop bleeding, the blood flowing out of the patient's neck will accumulate inside the incision. The blood then flows into the arc-shaped cylinder 43 through the inlet hole 444. At this time, the water pump 441 is activated, and the water pump 441 draws the blood out of the arc-shaped cylinder 43 through the inlet pipe 445 and discharges it into the receiving cavity 442 through the outlet pipe 443. This can promptly remove the blood from the patient's neck, preventing blood from flowing into the trachea when the doctor cuts the trachea and causing breathing discomfort to the patient, thereby improving the safety factor during the operation. After the operation is completed, the blood in the receiving cavity 442 can be drained.

[0067] Example 2:

[0068] See Figure 8As shown, the present invention also includes a sealing sleeve 5 for sealing the trachea. The sealing sleeve 5 includes a sealing inner core cap 51. A sealing tube 52 is detachably installed at the end of the sealing inner core cap 51. The diameter of the sealing inner core cap 51 is larger than the outer diameter of the sealing tube 52 to prevent the sealing inner core cap 51 from falling into the sealing tube 52 and to securely fix it to the sealing tube 52. A sealing tube core 53 is installed at the end of the sealing inner core cap 51 near the sealing tube 52. A fixing wing 54 is provided on the outer wall of the sealing tube 52 near the sealing inner core cap 51.

[0069] It should be noted that the end of the occlusion tube 52 away from the inner cap 51 has a slight curvature. This is used to control the correct direction of the suction tube or exchange tube entering the trachea in emergency situations where sputum obstructs the airway, or when it is necessary to replace the tracheostomy tube to connect to the ventilator. In addition, the outer diameter of the occlusion tube 52 can be designed to be 10mm, 8.5mm, 7mm, 5.5mm, and 4mm, respectively. The wall thickness of the occlusion tube 52 is 2mm, and the occlusion tube 52 does not require an air cuff. The use of occlusion tubes 52 with different outer diameters is to gradually replace them with smaller outer diameter occlusion tubes during the occlusion process, promoting synchronous healing of the tissue inside and outside the incision site.

[0070] During operation, the occlusion tube 52 is passed through the incision in the patient's neck and extended into the patient's trachea, so that the fixing wing 54 is against the patient's neck. Then, medical tape is used to fix the fixing wing 54 to the patient's neck. In actual use, the arc-shaped structure at the end of the occlusion tube 52 can control the direction of entry of the occlusion tube core 53 or suction tube. In this way, the occlusion cannula 5 can increase the patency of the patient's trachea and accurately observe and assess the patient's coughing ability. By changing the occlusion cannula 5 with different outer diameters, the gradual and synchronous healing of the incision skin and subcutaneous tissue is promoted, avoiding the formation of subcutaneous blind tube sinuses. If the patient experiences respiratory distress during the occlusion process, it can be quickly replaced with a conventional tracheostomy cannula for artificial ventilation.

[0071] During the procedure: First step: The patient lies on the operating table 1 with the patient's neck between the two actuators 4; then the doctor cuts open the skin tissue of the anterior wall of the patient's neck.

[0072] Step 2: Rotate any turntable 347. Turntable 347 drives the second bevel gear 345 to rotate via the rotating shaft 346. The second bevel gear 345 drives the self-locking screw 341 to rotate via the first bevel gear 344. The self-locking screw 341 drives the linkage plate 32, the retraction spring rod 33, and the horizontal plate 31 to move downward via the lifting block 342. During the movement, the horizontal plate 31 drives the extension plate 41 and the actuating plate 42 to move synchronously. When the actuating plate 42 is located at the incision site on the patient's neck, the actuating plate 42 and the arc-shaped cylinder 43 both drive the flexible compression pad 446 to press and stop the bleeding of the already cut skin tissue, thereby avoiding prolonged bleeding from the patient's neck.

[0073] During this period, the blood flowing from the patient's neck will accumulate inside the incision, and then the blood will flow into the arc-shaped cylinder 43 through the inlet hole 444; at this time, the water pump 441 is activated, and the water pump 441 draws out the blood inside the arc-shaped cylinder 43 through the water inlet pipe 445 and discharges it into the receiving cavity 442 through the water outlet pipe 443; thus, the blood in the patient's neck can be removed in a timely manner.

[0074] Step 3: Control the horizontal plate 31 to drive the actuator 4 to continue moving downward. At this time, the positioning pin 354 moves along the extension section under the V-shaped guide groove 353, so that the horizontal plate 31 drives the extension plate 41 and the actuating plate 42 to move downward and move away from the operating table 1. Thus, the actuating plate 42 can pull the skin tissue that has been cut in the patient's neck to both sides, so that the doctor can cut the patient's trachea.

[0075] Step 4: By adjusting the tilt angle of the extension sections on the upper and lower sides of the V-frame 352, the distance that the actuating plate 42 moves towards or away from the operating table 1 during its downward movement can be relatively increased or decreased, thus adapting to patients of different body types.

[0076] Step 5: After the surgery is completed, rotate the turntable 347 in the reverse direction. Through the cooperation between the turntable 347, the first bevel gear 344, the second bevel gear 345 and the self-locking screw 341, the lifting block 342, the linkage plate 32, the horizontal plate 31 and the actuator 4 can be moved upward as a whole, thereby removing the actuator 4 from the incision in the patient's neck; then the flexible compression pad 446 can be replaced.

[0077] Step 6: Pass the occlusion tube 52 through the incision in the patient's neck and extend it into the patient's trachea, so that the fixation wing 54 is against the patient's neck, and then use medical tape to fix the fixation wing 54 to the patient's neck; by changing the occlusion tube 5 with different outer diameters, promote the gradual and synchronous healing of the incision skin and subcutaneous tissue.
