Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, more particularly, it relates to an adjustable suction device for esophageal cancer surgery. BACKGROUND

[0002] In esophageal cancer surgery, the surgical site is located in the deep part of the chest, the space is narrow and the surrounding tissues and organs are dense, the clarity of the surgical field directly affects the operation accuracy and patient safety. During the operation, the surgical field often becomes blurred due to bleeding, tissue fluid exudation or residual irrigation fluid, and frequent suction and irrigation operations are required to maintain a clear field of view. However, the existing surgical suction and irrigation devices are usually designed as separate units, and medical personnel need to operate two devices alternately, which not only increases the complexity of the surgical process, but also may delay the exposure of the surgical field due to the replacement of the devices, prolong the operation time and increase the risk of postoperative complications.

[0003] In addition, the existing devices lack a coordinated linkage mechanism for suction and irrigation functions. When performing irrigation operations, the suction system often cannot respond in a timely manner, resulting in prolonged residence time of the irrigation fluid in the surgical field, which blurs the field of view again and forms an inefficient cycle of "irrigation - suction - re-irrigation". This not only wastes surgical time, but also increases the risk of intraoperative hypothermia in patients due to repeated irrigation. SUMMARY

[0055] Reference Figures 1-13 As shown.

[0056] Example 1 further illustrates an adjustable suction device for esophageal cancer surgery proposed in this invention.

[0057] An adjustable suction device for esophageal cancer surgery includes a housing 1, a fixing rod 2 fixedly connected to the top of the housing 1, at least two circular through holes 3 opened at the bottom of the housing 1, and a fixing member 4, which is snapped onto the fixing rod 2 and used to fix the fixing rod 2.

[0058] The suction pipe 5 is fixedly connected to the top of the fixed rod 2. The lower end of the suction pipe 5 passes through the fixed rod 2 and extends into the housing 1. The suction pipe 5 is matched with the circular through hole 3. The upper end of the suction pipe 5 is located at the top of the fixed rod 2. The suction pipe 5 can be connected to the suction port of the suction device in the prior art by means of existing technology.

[0059] The flushing pipe 6 has its upper end fixedly connected to the upper end face of the fixing rod 2, and its lower end passes through the top of the fixing rod 2 and extends into the housing 1. The lower end of the flushing pipe 6 is provided with a flushing head 7, which cooperates with the circular through hole 3. The flushing head 7 is used to flush the surgical site. The upper end of the flushing pipe 6 is located on the upper side of the fixing rod 2, and the upper end of the flushing pipe 6 is connected to the flushing equipment in the prior art through existing technology, which facilitates the flushing of the patient's surgical site.

[0060] The control mechanism is located inside the housing 1 and is used to control the up and down movement of the rinsing head 7.

[0061] The fastener 4 includes a retaining ring 8, which is engaged with the fixing rod 2. The retaining ring 8 is elastically provided with a retaining block 9, which is inserted into the circumferential wall of the fixing rod 2.

[0062] A connecting ring 10 is fixedly connected to the outer ring wall of the retaining ring 8. A buckle 11 is fixedly connected to the outer ring wall of the connecting ring 10. One end of the connecting ring 10 is inserted into the buckle 11. One end of the connecting ring 10 is made of a flexible material such as rubber or TPU. The side wall of the connecting ring 10 is provided with retaining teeth. The buckle 11 is existing technology. The buckle 11 cooperates with the retaining teeth on the connecting ring 10. By restricting the retaining teeth on the connecting ring 10 through the buckle 11, the end of the connecting ring 10 is fixed, which makes it convenient for medical staff to adjust the length of the connecting ring 10.

[0063] At least two sets of limiting holes 12 are provided on the outer ring wall of the fixing rod 2. The end of the locking block 9 is inserted into the limiting hole 12. Each set of limiting holes 12 has at least two holes and is symmetrically arranged about the fixing rod 2. There are at least two locking blocks 9 and they are symmetrically arranged about the fixing rod 2. The end of the locking block 9 inserted into the limiting hole 12 is tapered, which facilitates the insertion of the locking block 9 into the limiting hole 12. At the same time, the position of the fixing rod 2 is fixed by the cooperation between the locking block 9 and the limiting hole 12.

[0064] A limiting cavity 13 is formed inside the retaining ring 8. A first spring 14 is fixedly connected to the side wall of the limiting cavity 13. One end of the first spring 14 is fixedly connected to a limiting plate 15. A retaining block 9 is fixedly connected to the side wall of the limiting plate 15, and one end of the retaining block 9 passes through the side wall of the limiting cavity 13 and is inserted into the limiting hole 12.

[0065] A vertically movable annular push plate 16 is provided inside the limiting cavity 13. A second spring 17 is fixedly connected to the annular push plate 16, with one end of the second spring 17 fixedly connected to the bottom of the limiting cavity 13. A trapezoidal block 37 is fixedly connected to the annular push plate 16. The small end of the trapezoidal block 37 is located between the limiting plate 15 and the side wall of the limiting cavity 13, and the trapezoidal block 37 is located on one side of the locking block 9. The inclined surface of the trapezoidal block 37 is opposite to the limiting plate 15. During the process of the annular push plate 16 driving the trapezoidal block 37 to move downward, the inclined surface of the trapezoidal block 37 pushes against the side wall of the limiting plate 15, causing the limiting plate 15 to move towards the second spring 9. The first spring 14 is pushed in the direction of the first spring 14, and the locking block 9 retracts into the limiting cavity 13. During the process of the limiting plate 15 moving in the direction of the first spring 14, the first spring 14 is gradually contracted due to the pushing of the limiting plate 15. When the end of the locking block 9 away from the limiting plate 15 moves into the limiting cavity 13, the first spring 14 is fully contracted. At this time, the height of the locking ring 8 can be adjusted as needed. There are two locking rings 8, which makes it easy to fix the fixing rod 2 in the hand of the medical staff, thereby avoiding the medical staff from operating the housing 1 by holding the fixing rod 2, which brings convenience to the medical staff.

[0066] A push rod 18 is fixedly connected to the side wall of the annular push plate 16 away from the second spring 17. One end of the push rod 18 passes through the limiting cavity 13 and is fixedly connected to the arc-shaped push plate 19. A protrusion is provided on the outer arc wall of the arc-shaped push plate 19. Medical staff can push the protrusion toward the opposite side of the retaining ring 8, thereby pushing the trapezoidal block 37 toward the annular push plate 16, thereby controlling the movement of the retaining block 9.

[0067] A fixing plate 20 is fixedly connected to the inner wall of the housing 1, and the lower end of the suction pipe 5 is fixedly connected to the upper surface of the fixing plate 20.

[0068] A rectangular pipe 21 is fixedly connected to the lower surface of the fixed plate 20. The bottom of the rectangular pipe 21 is closed, and a first suction pipe 22 is fixedly connected to the bottom of the rectangular pipe 21. The first suction pipe 22 cooperates with the circular through hole 3. A symmetrically arranged cover plate 23 is rotatably connected to the bottom of the rectangular pipe 21. The cover plate 23 covers the upper end surface of the first suction pipe 22.

[0069] A second suction tube 24 is fixedly connected to the side wall of the rectangular pipe 21. The upper end of the second suction tube 24 is connected to the rectangular pipe 21, and the upper port of the second suction tube 24 is matched with the cover plate 23.

[0070] A suction box 25 is slidably connected to the inner side of the housing 1, symmetrically arranged with respect to the rectangular pipe 21. The lower end of the second suction tube 24 is fixedly connected to the top of the suction box 25 and communicates with it. A suction head 26 is fixedly connected to the bottom of the suction box 25. Suction holes 27 are symmetrically arranged with respect to the circular through hole 3 at the bottom of the housing 1. The suction head 26 cooperates with the suction hole 27, and the number of suction heads 26 is consistent with the number of suction holes 27. The lower end of the suction head 26 can be inserted into the suction hole 27. When it is necessary to rinse the patient's surgical site, the rinsing fluid is sprayed onto the patient's surgical site through the rinsing head 7, and the rinsing fluid is sucked into the housing 1 through the suction head 26, thereby rinsing the patient's surgical site and preventing the rinsing fluid from remaining on the patient's surgical site, making it easier for medical staff to continue the operation. The lower end of the first suction tube 22 is located between the suction head 26 and the rinsing head 7, making it easy for the first suction tube 22 to draw the fluid from the patient's surgical site through the circular through hole 3 and the suction hole 27.

[0071] A flushing box 28 is provided directly below the flushing pipe 6. At least two connecting rods 29 are fixedly connected to the upper surface of the flushing box 28, and the ends of the connecting rods 29 are fixedly connected to the suction box 25.

[0072] A connecting pipe 30 is fixedly connected to the lower end of the flushing pipe 6. The lower end of the connecting pipe 30 is fixedly connected to the flushing box 28, and the flushing head 7 is fixedly connected to the bottom of the flushing box 28.

[0073] The control mechanism includes an electric telescopic rod 31, which is vertically fixed to the upper surface of the fixed plate 20. The moving end of the electric telescopic rod 31 passes through the fixed plate 20 and is fixedly connected to the upper surface of the rinsing box 28.

[0074] A rotating rod 33 is fixedly connected to the gear 32 and the cover plate 23. The end of the rotating rod 33 is rotatably connected to the side wall of the rectangular pipe 21 and passes through the side wall of the rectangular pipe 21 and is fixedly connected to the gear 32.

[0075] Rack 34 is vertically fixed to the upper surface of connecting rod 29. Rack 34 meshes with gear 32. When electric telescopic rod 31 drives flushing box 28 to move upward, it also drives rack 34 to move upward. Due to the meshing of rack 34 and gear 32, rack 34 pushes gear 32 to rotate during the upward movement of rack 34, and also causes rotating rod 33 to rotate.

[0076] An L-shaped sliding block 35 is fixedly connected to the top of the suction box 25.

[0077] A vertically arranged strip groove 36 is provided on the inner wall of the housing 1, and the horizontal section of the L-shaped sliding block 35 is slidably connected in the strip groove 36.

[0078] At least two first rubber plugs 38 are fixedly connected to the lower surface of the cover plate 23. The position of the first rubber plug 38 corresponds to the position of the upper port of the first suction tube 22. The lower end of the first rubber plug 38 is tapered, and the diameter of the upper end face of the first rubber plug 38 is equal to the diameter of the inner ring wall of the first suction tube 22, so that the first rubber plug 38 can be inserted into the upper end face of the first suction tube 22, thereby achieving the closure of the upper port of the first suction tube 22.

[0079] At least two second rubber plugs 39 are fixedly connected to the upper surface of the cover plate 23. The position of the second rubber plugs 39 corresponds to the position of the upper port of the second suction tube 24. The upper end of the second rubber plug 39 is tapered, and the diameter of the lower end face of the second rubber plug 39 is equal to the diameter of the inner ring wall of the second suction tube 24, so that the second rubber plug 39 can be inserted into the upper port of the second suction tube 24.

[0080] Working principle: When medical staff have difficulty controlling the suction head 26 by holding surgical instruments, they can engage the retaining ring 8 on the fixing member 4 with the fixing rod 2. The retaining block 9 is inserted into the limiting hole 12 of the fixing rod 2 under the action of the first spring 14, forming a preliminary fixation. Medical staff can adjust the diameter of the inner ring wall of the connecting ring 10 by pulling one end of the connecting ring 10 away from the buckle 11. The buckle 11 and the retaining teeth lock the position, fixing the fixing rod 2 to the hand, fingers or surgical instruments, avoiding fatigue from hand operation and improving operational stability. When it is necessary to adjust the distance between the two fixing members 4, the medical staff manually pushes the arc-shaped push plate 19 towards the retaining ring 8 and pushes the push rod 18 into the limiting cavity 13, which at the same time drives the annular push plate 16 and the trapezoidal block 37 to move. During the movement, the trapezoidal block 37 pushes the limiting plate 15 away from the retaining block 9 through its inclined surface. When the end of block 9 disengages from the limiting hole 12, both the first spring 14 and the second spring 17 are in a contracted state. At this time, medical staff can adjust the distance between the two fixing parts 4 as needed, and then loosen the arc-shaped push plate 19. Due to the elastic force generated when the second spring 17 extends, the second spring 17 pushes the annular push plate 16 away from the limiting plate 15 and drives the trapezoidal block 37 to move. At the same time, due to the pushing of the trapezoidal block 37 and the elastic force generated when the first spring 14 extends, the first spring 14 pushes the limiting plate 15 towards the locking block 9, so that the end of the locking block 9 passes through the side wall of the retaining ring 8 and is inserted into the limiting hole 12. This realizes the adjustment of the distance between the two fixing parts 4, which increases the stability of the fixing rod 2 to a certain extent and makes it easier for medical staff to fix the position of the fixing rod 2. The inner ring wall of the retaining ring 8 is provided with a through hole for the locking block 9 to pass through, so that the locking block 9 passes through the side wall of the retaining ring 8 and is inserted into the limiting hole 12.

[0081] The upper end of the suction tube 5 is connected to an external suction device through existing technology such as a connecting tube, and the lower end is diverted to the first suction tube 22 and the second suction tube 24 through the rectangular tube 21. When the cover plate 23 is opened, the first suction tube 22 directly suctions the fluid from the surgical site through the circular through hole 3 and the suction hole 27, thereby cleaning the fluid, such as blood and secretions, from the patient's surgical site.

[0082] The flushing pipe 6 is connected to an external flushing device via existing technology, such as a connecting pipe. When flushing of the patient's surgical site is required, the electric telescopic rod 31 is activated. The moving end of the electric telescopic rod 31 pushes the flushing box 28 downward, causing the flushing head 7, suction box 25, and suction head 26 to move downward. Simultaneously, as the flushing box 28 moves downward, it also causes the connecting rod 29 and rack 34 to move downward. During the downward movement of the rack 34, the rack 34 drives the rotating rod 33 to rotate through meshing with the gear 32. The rotating rod 33 causes the upper end of the cover plate 23 to rotate downward. When the cover plate 23 rotates to a horizontal position, the first rubber... The plug 38 is inserted into the upper port of the first suction tube 22 to seal the upper port of the first suction tube 22. At the same time, the lower ends of the flushing head 7 and the suction head 26 are located in the circular through hole 3 and the suction hole 27, respectively. The flushing device connected to the flushing pipe 6 is activated. The flushing fluid in the flushing device enters the flushing box 28 through the flushing pipe 6 and is then sprayed onto the patient's surgical site through the flushing head 7, thereby cleaning the patient's surgical site. At the same time, the suction device connected to the suction pipe 5 is activated. The suction device draws out the flushing fluid and secretions from the patient's surgical site through the suction pipe 5, the suction box 25, and the suction head 26, thereby keeping the surgical field clear.

[0083] Because the bottom of the outer casing 1 is arc-shaped, and the circular through-hole 3 is located directly below the outer casing 1, while the suction holes 27 are located on both sides of the circular through-hole 3, the position of the circular through-hole 3 is lower than the position of the suction holes 27. This allows the lower port of the rinsing head 7 to be close to the patient's surgical site. When the rinsing fluid is sprayed out through the rinsing head 7, the rinsing fluid is directly sprayed onto the patient's surgical site. At the same time, because the suction force in the suction device connected to the end of the suction pipe 5 remains unchanged, and the upper port of the lower first suction tube 22 is blocked, while the upper port of the second suction tube 24 is opened, the second suction tube 24 draws the rinsing fluid and secretions from the patient's surgical site through the suction hole 27. Meanwhile, because the rectangular pipe 21 is connected to the suction head 26 through the second suction tube 24 and the suction box 25, and the suction head 26 is located inside the suction hole 27, the suction pipe 5 draws the rinsing fluid and secretions from the patient's surgical site only through the suction hole 27. This facilitates the cleaning of the rinsing fluid and secretions from the patient's surgical site and keeps the surgical field clear.

[0084] When flushing is not required for the patient's surgery, the electric telescopic rod 31 is activated. The moving end of the electric telescopic rod 31 drives the flushing box 28 to move upward, and simultaneously drives the flushing head 7, suction box 25, suction head 26, and rack 34 to move upward. As the rack 34 moves upward, it engages with the drive gear 32 to rotate in the opposite direction, causing the end of the cover plate 23 away from the rotating rod 33 to rotate upward. When the cover plate 23 is vertical, the second rubber plug 39 is inserted into the upper port of the second suction tube 24, thereby blocking the upper port of the second suction tube 24. At this time, the upper port of the first suction tube 22 is open, and the lower ends of the flushing head 7 and suction head 26 are located above the circular through hole 3 and suction hole 27. The flushing equipment connected to the flushing pipe 6 is closed, so that the suction device at the end of the suction pipe 5 can draw out the fluid and secretions from the patient's surgical site through the first suction tube 22. The fluid and secretions from the patient's surgical site enter the housing 1 through the circular through hole 3 and suction hole 27, thereby achieving the cleaning of the fluid from the patient's surgical site.

[0085] The extension and retraction of the electric telescopic rod 31 not only adjusts the position of the rinsing head 7, but also drives the suction box 25 to move synchronously through the connecting rod 29, ensuring that the position of the suction head 26 matches that of the rinsing head 7. At the same time, when the rack 34 moves with the rinsing box 28, it meshes with the gear 32 to drive the cover plate 23 to rotate. When it rises, the cover plate 23 opens the first suction tube 22 and closes the second suction tube 24, and when it falls, it does the opposite, realizing intelligent switching of the suction path to adapt to the needs of different surgical stages. The first suction tube 22, the second suction tube 24, and the connecting pipe 30 are all telescopic flexible hoses such as corrugated pipes, which facilitates the up and down movement of the rinsing box 28 and the suction box 25.

[0086] The elastic snap-fit ​​design of the fastener 4 facilitates quick adjustment of the height of the fixing rod 2, and the adjustable length of the connecting ring 10 adapts to different surgical scenarios, reducing the operational burden on medical staff.

[0087] The adjustable height of the irrigation head 7 and the function of switching the suction path ensure the coordinated precision of irrigation and suction, avoid residual fluid from affecting the surgical field of vision, and reduce the risk of infection.

[0088] Integrating suction and irrigation functions, the device allows for simultaneous operation through a single housing 1, reducing the frequency of surgical instrument changes, shortening surgical time, and improving treatment efficiency. It effectively solves the problems of blurred vision and cumbersome operation in esophageal cancer surgery, providing strong support for precision surgery.

[0089] The tapered fit between the locking block 9 and the limiting hole 12 enhances the reliability of the fixation. The sliding of the L-shaped sliding block 35 in the strip groove 36 ensures that the suction box 25 moves smoothly and that the equipment remains stable during high-frequency operation. At the same time, medical staff can also hold the fixing rod 2 and use the flushing head 7 and suction head 26 in the housing 1 to flush the patient's surgical site and aspirate the flushing fluid and secretions, which brings convenience to medical staff.
