Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an auxiliary bracket and wound flushing and aspiration integrated device and method. Background Art

[0002] During clinical surgery, flushing and negative pressure drainage operations are usually performed using separate devices, and the surgeon is required to hold the drainage device (17) continuously during the operation to perform alternating operations. Clinical practice has verified that the existing technical solutions have three significant defects:

[0003] 1. Continuous handheld operation requires the surgeon to maintain a specific posture for extended periods. In complex surgical scenarios, such as orthopedics, a single procedure requires an average of 27 ± 5 irrigation-drainage switching operations. This high level of physical exertion not only increases surgeon fatigue but can also lead to deviations in surgical field positioning due to muscle tremors, compromising the precise execution of subsequent surgical steps.

[0004] 2. While existing equipment can switch between flushing and drainage functions, there are technical blind spots in postoperative tubing cleaning. Clinical data show that removing residual blood clots and tissue debris from postoperative tubing takes an average of 42 ± 8 minutes and requires multiple steps, including rough cleaning, enzymatic cleaning, and high-temperature disinfection.

[0005] 3. To prevent clogging with tissue debris, the drainage tip is equipped with a filter assembly. However, during orthopedic surgery, bone debris particle size varies widely (0.5-3.2mm), resulting in a filter clogging rate as high as 41.6%. This necessitates frequent tip replacement during surgery, with an average frequency of 4.3 per procedure for complex surgeries. This not only prolongs surgery time but also increases medical consumables consumption.

[0006] In response to the above problems, the present invention document proposes an integrated device and method for auxiliary stent and wound flushing and suction. Summary of the Invention

[0007] The purpose of the present invention is to solve the shortcomings of the existing drainage device, which requires manual hand-held operation, the inability to effectively clean the inside of the drainage device, and the need for multiple spare drainage device ends, and to propose an auxiliary bracket and wound flushing and suction integrated device and method.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] An auxiliary bracket for fixing a drainage device at multiple angles, comprising:

[0010] bracket body;

[0011] A support arm is slidably mounted on the outer wall of the bracket body, and a C-shaped clamp is provided at the bottom thereof;

[0012] An adjustment structure comprising a sliding seat slidably connected to the outer wall of the support arm, a rotating seat rotatably connected to the sliding seat via a damping shaft, a crossbar rotatably connected to the rotating seat via the damping shaft, and a damping universal joint rotatably connected to one end of the crossbar, wherein the C-shaped clamp is fixed to the end of the damping universal joint;

[0013] a fixing structure comprising a plurality of slots distributed axially along the bracket body, a pin rod slidably disposed in the support arm, and a shift plate connected to the pin rod, wherein the shift plate is reset by a first spring to allow the pin rod to be inserted into the slot;

[0014] The support arm is height-adjusted by the fixing structure, and the spatial angle of the C-shaped clamp is adjusted by the adjusting structure.

[0015] As a further improvement of the above technical solution:

[0016] The fixing structure also includes a first fixing ring fixed to the outer wall of the bracket body, a sliding cylinder slidably sleeved on the outer wall of the bracket body, and a tension spring connecting the first fixing ring and the sliding cylinder, wherein the tension spring is used to provide a reset force when the pin rod is disengaged from the slot.

[0017] A plurality of holders are provided on the top of the support arm for fixing the drainage tube and the flushing tube.

[0018] A wound irrigation and suction integrated device comprising:

[0019] the auxiliary bracket mentioned above;

[0020] The drain is clamped in the C-shaped clamp, with the two sides connected to the flushing joint and the drainage joint respectively, and the bottom is detachably connected to the end with a filter;

[0021] The switching structure includes a rotating cylinder rotatably disposed in the diverter, a driving rod slidably connected to the rotating cylinder, and a flushing channel, a drainage channel, and an L-shaped channel provided in the rotating cylinder. A closing plate is fixed to the bottom end of the driving rod for closing or opening the L-shaped channel.

[0022] An operating structure includes a negative pressure pump, a drainage tube, and a storage box fixed to the bracket body, wherein the negative pressure pump is connected to the drainage tube to generate negative pressure, and the storage box is connected to the flushing connector via a booster pump and a connecting hose;

[0023] The rotating drum is switched to:

[0024] When the irrigation channel is aligned with the irrigation connector, perform wound irrigation;

[0025] When the drainage channel is aligned with the drainage connector, negative pressure drainage is performed;

[0026] When the L-shaped channel is aligned with the flushing connector and the closing block is opened, the drainage channel and the drainage connector are flushed in reverse.

[0027] As a further improvement of the above technical solution:

[0028] The top end of the driving rod extends to the top of the drain and is fixed with a pressing head. The pressing head is reset by a second spring. Three marking balls are provided on its outer wall. Two marking plates corresponding to the marking balls are fixed on the top of the drain.

[0029] Also included is a cleaning structure, the cleaning structure comprising:

[0030] a cleaning tank, fixed to the top of the storage tank;

[0031] A rotating disk is rotatably arranged at the bottom of the cleaning box, and a plurality of tapered holes are provided on its surface;

[0032] A driving motor drives the rotating disk to rotate through a gearbox;

[0033] The universal ball is rotatably embedded in the cleaning box, with the top of the universal ball being connected to the liquid inlet pipe and the bottom being connected to the liquid outlet pipe. The liquid inlet pipe is connected to the connecting hose through the return pipe.

[0034] The output shaft of the driving motor is fixed with a second synchronous wheel, the top of the cleaning box is slidably connected with a first synchronous wheel, and the first synchronous wheel is connected to the second synchronous wheel through a synchronous belt.

[0035] A first hemisphere is provided on the top of the first synchronous wheel, and a placement plate with multiple second hemispheres is fixed on the outer wall of the liquid inlet pipe. The first hemisphere collides with the second hemisphere to drive the liquid outlet pipe to swing at multiple angles.

[0036] In this application, the method for using the integrated wound irrigation and aspiration device includes the following steps:

[0037] S1. Move the support body to the side of the operating table and secure the drain in the C-shaped clamp. Move the paddle to release the brake on the support arm. Manually adjust the support arm to the target height. The pin will automatically reset and lock under the action of the first spring.

[0038] S2. Through the coordinated action of the rotating seat, sliding seat and damping universal joint, the diverter can be flexibly positioned to the required position and angle, realizing hands-free operation;

[0039] S3. Use the pressing head to rotate the rotating cylinder until the drainage channel and the drainage connector are aligned. After confirming the alignment using the marking ball and the marking plate, the negative pressure pump is started to draw blood from the surgical area through the drainage connector and the drainage channel into the drainage cylinder.

[0040] S4. Rotate the rotating barrel to align the irrigation channel with the irrigation connector. The booster pump delivers cleaning fluid to the surgical site through the storage tank for irrigation. Rotate the rotating barrel again to align the L-shaped channel with the irrigation connector. Press the pressing head to release the sealing block from the L-shaped channel. The cleaning fluid flows back through the L-shaped channel, drainage channel, and drainage connector to flush the pipeline.

[0041] S5. Replace the clogged tip to the rotating disk. The driving motor drives the rotating disk to rotate at a low speed. The cleaning fluid is flushed through the connecting hose, universal ball and liquid outlet pipe to the tip. After cleaning, the tip can be used again in this operation.

[0042] S6. The driving motor drives the first synchronous wheel to rotate through the synchronous belt. The collision between the first hemisphere and the second hemisphere causes the liquid inlet pipe and the liquid outlet pipe to swing, achieving multi-angle cleaning; the bearing block ensures that the liquid outlet pipe returns to a vertical state when there is no collision.

[0043] Beneficial effects: In the present invention, a flushing channel, a drainage channel and an L-shaped channel are provided in the rotating cylinder, the flushing channel cooperates with the flushing joint, the drainage channel cooperates with the drainage joint, the L-shaped channel cooperates with the flushing joint, a sealing block is sealed and slidably connected in the second sliding groove, and the sealing block is fixedly sleeved on the outer wall of the driving rod; the flushing joint cooperates with the flushing channel, and the cleaning liquid can complete the flushing operation through the drainer, the drainage channel cooperates with the drainage joint, and the drainage operation can be performed through the drainer. When it is necessary to flush the inner wall of the drainage channel and the drainage joint, the L-shaped channel and the drainage channel cooperate with the flushing joint and the drainage joint respectively, and the driving rod is pressed, the sealing block releases the blockade of the L-shaped channel, and then the cleaning liquid entering from the flushing joint can enter the drainage channel and the drainage joint through the L-shaped channel to complete the flushing operation;

[0044] In the present invention, the sliding seat and the rotating seat, as well as the rotating seat and the crossbar, are all rotatably connected via a damping shaft. One end of the crossbar is provided with a damping universal joint for rotation, thereby enabling the C-shaped clamp to be adjusted to a variety of angles, thereby irrigating and draining different surgical sites of the patient without the need for manually holding a drainage device.

[0045] In the present invention, the second synchronous wheel and the first synchronous wheel are connected through a synchronous belt transmission, the outer wall of the liquid inlet pipe is fixed with a placement plate, the bottom of the placement plate is fixed with multiple second hemispheres, and the top side of the first synchronous wheel is fixed with a first hemisphere; when the driving motor drives the rotating disk to slide and rotate, the cooperation of the second synchronous wheel, the first synchronous wheel and the synchronous belt drives the first synchronous wheel to rotate, and the first synchronous wheel drives the first hemisphere to rotate, and the contact between the first hemisphere and the multiple second hemispheres can drive the liquid inlet pipe and the liquid outlet pipe to rotate to different angles, so that the liquid outlet pipe can clean the inside of the end head and the filter from different angles, which is convenient for reuse in this operation.

[0046] In the present invention, the drainer can be clamped in the C-shaped clamp and adjusted to various angles to flush and drain different surgical sites of the patient without the need for manual holding of the drainer. In addition, the different operating states of the drainer can be adjusted by switching the structure, so that flushing and drainage can be completed and the inner walls of the drainage channel and the drainage joint can be flushed. In addition, when flushing, the cleaning liquid in the connecting hose can be drained to the blocked end for flushing, so that it can be used again in the current operation.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0061] Example 1: Reference Figure 1-Figure 3 , a bracket, relates to the field of medical device technology, and is used to enable the drain 17 to drain and flush at different angles. It includes a long strip of bracket body 1, a bottom plate is installed at the bottom of the bracket body 1, and a plurality of universal wheels with brakes are fixed under the bottom plate by bolts to facilitate its movement. The bracket body 1 can be made of metal or plastic material to ensure a stable structure. On one side of the bracket body 1, a support arm 3 is provided, and the length and shape of the support arm 3 can be designed according to actual needs. At the bottom of the support arm 3, a C-type clamp 16 is fixed, and the C-type clamp 16 is used to clamp the drain 17, and the opening size thereof can be adjusted to accommodate drains 17 of different sizes.

[0062] Among them, the form of the bracket body 1 can be: 1. Foldable truss structure: In the transportation scenario, the bracket body 1 can be made of hexagonal honeycomb aluminum material, with a hinge folding mechanism set in the middle. After unfolding, it is locked by a pin to form a torsion-resistant structure, and the volume is reduced by 60% in the folded state; 2. Modular splicing columns: In response to the requirements of complex surgical layout, the bracket body 1 is designed as a standard interface splicing unit. The height of each column is 15 cm, and it can be vertically stacked to 3 layers through quick-release buckles. M6 threaded holes are reserved on the side for installing expansion modules such as sterile instrument trays.

[0063] refer to Figure 1 and Figure 2 The adjustment mechanism includes a sliding groove formed in the outer wall of support arm 3, through which a sliding seat 11 is slidably connected to support arm 3. The bottom of sliding seat 11 is rotatably connected to a rotating seat 12 via a damping shaft. Rotating seat 12 is further rotatably connected to a crossbar 14 via a damping shaft. One end of crossbar 14 is rotatably connected to a damping universal joint 15, and a C-type clamp 16 is fixed to one end of damping universal joint 15.

[0064] Specifically, through the cooperation of the sliding seat 11, the rotating seat 12, the cross bar 14 and the damping universal joint 15, the drain device 17 clamped in the C-shaped clamp 16 can be adjusted to various angles, thereby flushing and draining different surgical sites of the patient.

[0065] refer to Figure 1 At the top of the support arm 3, a plurality of holders 13 are equidistantly welded or integrally formed, and the holders 13 are used to limit the drainage tube.

[0066] refer to Figure 1 and Figure 3 The fixing structure includes a first fixing ring 4 fixedly sleeved on the outer wall of the bracket body 1 and located above the support arm 3. A sliding cylinder 2 fixedly connected to the support arm 3 is slidably sleeved on the outer wall of the bracket body 1. In order to be able to adjust the height of the support arm 3 on the bracket body 1, a plurality of slots 9 are equidistantly provided on one side of the bracket body 1. A pin rod 6 is slidably provided in the support arm 3, and the pin rod 6 cooperates with the slot 9 to fix the height of the support arm 3. A tension spring 5 is fixedly connected between the first fixing ring 4 and the sliding cylinder 2. The function of the tension spring 5 is to prevent the support arm 3 from falling when the brake of the slot 9 and the pin rod 6 is released. A first sliding groove 10 is provided at the bottom of the support arm 3, and the selector plate 7 is slidably connected in the first sliding groove 10. A first spring 8 is fixedly connected to the side of the selector plate 7 away from the bracket body 1, and one end of the first spring 8 is fixed in the first sliding groove 10. The side of the selector plate 7 away from the first spring 8 is fixedly connected to the pin rod 6. The shift plate 7 cooperates with the pin rod 6 to drive the pin rod 6 to release the plug-in fit with the slot 9; the shift plate 7 cooperates with the first spring 8 to drive the pin rod 6 to return to its original position and to engage with the slot 9.

[0067] Specifically, to adjust the height of support arm 3, first, shift plate 7 outward. This shift plate 7 drives pin 6 out of slot 9, releasing the brake between support arm 3 and bracket body 1. Next, manually raise or lower support arm 3 to the desired position. Once support arm 3 reaches the desired position, pin 6 is reinserted into slot 9 under the elastic force of first spring 8, completing the height adjustment of support arm 3.

[0068] Through the above steps, the auxiliary bracket can achieve drainage and flushing of the drainer 17 at different angles, and can also adjust the height of the support arm 3 according to actual needs, thereby improving the flexibility and convenience of use.

[0069] Reference Figure 6 、 Figure 7 and Figure 9 , an integrated wound irrigation and suction device, relates to the field of medical device technology, includes the above-mentioned bracket, and also includes a rotating cylinder 23 arranged in the drain 17, and the rotating cylinder 23 can rotate in the drain 17. A driving rod 24 is slidably connected to the rotating cylinder 23 through a slide slider structure. The two sides of the drain 17 are respectively fixedly connected with a flushing joint 18 and a drainage joint 19. The bottom end of the drain 17 is threadedly connected to the end head 20, and a filter is provided in the end head 20, which can intercept blood, flesh tissue and bone residue in the liquid during the drainage process. The outer wall of the bracket body 1 is fixedly sleeved with a mounting plate 53, and the mounting plate 53 is provided with an operating structure for drainage and flushing, which includes a negative pressure pump 36, a drainage cylinder 35 and a storage box 37 fixed to the top of the mounting plate 53 by bolts.

[0070] Reference Figure 5 The operating structure also includes a booster pump 38 fixed to the bottom inner wall of the storage box 37 through a frame. A connecting hose 39 is fixed to the liquid outlet of the booster pump 38, and the connecting hose 39 is connected to the flushing connector 18. When flushing is required, the booster pump 38 is started, and the booster pump 38 transports the cleaning liquid in the storage box 37 through the connecting hose 39 to the flushing connector 18, and then into the diverter 17 to complete the flushing operation.

[0071] Reference Figure 5 The liquid inlet end of the drainage tube 35 is connected to the drainage connector 19 through the drainage tube, and the air inlet end of the negative pressure pump 36 is connected to the air outlet end of the drainage tube 35 through the air inlet tube. When drainage is required, the negative pressure pump 36 is started, which creates a negative pressure in the drainage tube 35, thereby sucking the liquid from the wound into the drainage tube 35 through the drain 17, the drainage connector 19 and the drainage tube.

[0072] Drainage efficiency: The negative pressure pump 36 creates a negative pressure state in the drainage tube 35, thereby improving the drainage efficiency and ensuring that the liquid in the wound can be discharged in time.

[0073] The holder 13 on the top of the support arm 3 is used to fix and limit the drainage tube and the connecting hose 39 to prevent the pipeline from shaking or falling off during operation.

[0074] Reference Figure 6 、 Figure 7 and Figure 9 The switching structure includes a flushing channel 25, a drainage channel 26 and an L-shaped channel 27 arranged in the rotating cylinder 23, and a second fixed ring 22 fixed in the drainer 17. The flushing channel 25 cooperates with the flushing joint 18 to complete the flushing operation, the drainage channel 26 cooperates with the drainage joint 19 to perform the drainage operation, and the L-shaped channel 27 cooperates with the flushing joint 18, and its bottom end is connected to the drainage channel 26, which is used to inject cleaning liquid into the drainage channel 26 to clean the inner wall of the drainage channel 26 and the drainage joint 19. A second sliding groove 28 is provided on the inner wall of the bottom of the L-shaped channel 27, and a sealing block 29 is sealed and slidably connected in the second sliding groove 28. The sealing block 29 is fixedly sleeved on the outer wall of the driving rod 24, and the driving rod 24 slides through the rotating cylinder 23. The bottom end of the driving rod 24 is fixed with a sealing plate 21 that closes the second fixed ring 22.

[0075] Specifically, the rotating cylinder 23 is driven to rotate by the driving rod 24. When the flushing joint 18 cooperates with the flushing channel 25, the cleaning liquid can complete the flushing operation through the drain 17; when the drainage channel 26 cooperates with the drainage joint 19, the drainage operation can be performed through the drain 17; when it is necessary to flush the inner wall of the drainage channel 26 and the drainage joint 19, the L-shaped channel 27 and the drainage channel 26 cooperate with the flushing joint 18 and the drainage joint 19 respectively, and the driving rod 24 is pressed, the closing plate 21 closes the second fixing ring 22, and the closing block 29 releases the seal on the L-shaped channel 27, thereby allowing the cleaning liquid entering from the flushing joint 18 to enter the drainage channel 26 and the drainage joint 19 through the L-shaped channel 27, completing the flushing operation.

[0076] Flushing and drainage function: The switching structure can flexibly realize the switching between flushing and drainage operations to meet the different needs during wound treatment.

[0077] Internal cleaning function: It can clean the inner wall of the drainage channel 26 and the drainage joint 19 to avoid bacterial growth and blockage problems caused by inadequate cleaning.

[0078] Reference Figure 7 and Figure 8 The top end of the driving rod 24 extends to the top of the diverter 17 and fixes the pressing head 30. The bottom end of the pressing head 30 is rotatably connected to the rotating ring 33, and a second spring 34 is fixed between the bottom of the rotating ring 33 and the top of the diverter 17.

[0079] Reference Figure 7 and Figure 8Three marking balls 31 are fixed to the outer wall of the pressing head 30, corresponding to the liquid inlet ends of the flushing channel 25, drainage channel 26, and L-shaped channel 27. Two marking plates 32 are fixed to the top of the drain 17. The two marking plates 32 are placed on both sides of the pressing head 30, corresponding to the flushing connector 18 and drainage connector 19 respectively.

[0080] Specifically, the second spring 34 can move the pressing head 30 upward and reset and block the L-shaped channel 27 through the closing block 29. Through the cooperation of the marking ball 31 and the marking plate 32, the operator can determine the rotation position of the flushing channel 25, the drainage channel 26 and the L-shaped channel 27, facilitating accurate operation.

[0081] Reference Figure 5 and Figure 10 A cleaning tank 40 is bolted to the top of the storage tank 37. Inside this tank is a cleaning mechanism for cleaning clogged endpieces 20. This cleaning mechanism includes a return pipe, located above the cleaning tank 40 and connected to the connecting hose 39. A solenoid valve is installed on the return pipe. When the endpiece 20 becomes clogged and needs to be flushed, the endpiece 20 is placed in a safe position, which opens the solenoid valve and allows some cleaning fluid to flow through the return pipe into the cleaning tank 40, flushing and cleaning the endpiece 20.

[0082] Reference Figure 10 The cleaning structure also includes a rotating disk 41 rotatably mounted on the bottom inner wall of the cleaning tank 40. The rotating disk 41 has multiple tapered holes formed therein for receiving the tip 20. A gearbox 43 is secured to the top inner wall of the cleaning tank 40, with the output shaft of the gearbox 43 fixedly connected to the top of the rotating disk 41. A drive motor 42 is secured to the top of the cleaning tank 40 via a frame, with the output shaft of the drive motor 42 fixedly connected to the input shaft of the gearbox 43. When the drive motor 42 is started, the gearbox 43 cooperates to drive the rotating disk 41 to rotate slowly.

[0083] Specifically, the driving motor 42 can drive the rotating disk 41 to rotate through the gearbox 43, thereby providing conditions for subsequent comprehensive flushing of the end head 20.

[0084] Reference Figure 10 A universal ball 44 is rotatably mounted within the cleaning tank 40, with a cavity defined within it. A liquid inlet pipe 45 and a liquid outlet pipe 46 are fixedly connected to the top and bottom of the universal ball 44, respectively, connecting the liquid inlet pipe 45 to the return pipe. When the booster pump 38 is activated and works in conjunction with the diverter 17 for flushing, the solenoid valve on the return pipe opens, allowing the cleaning fluid in the connecting hose 39 to flow through the return pipe into the liquid outlet pipe 46. Simultaneously, the drive motor 42 slowly rotates the rotating disk 41, allowing the liquid outlet pipe 46 to flush the multiple terminals 20 on the rotating disk 41.

[0085] Specifically, this part is set to enable the cleaning liquid in the connecting hose 39 to pass through the reflux pipe and the channel in the universal ball 44, and be sprayed out from the liquid outlet pipe 46 to flush the end head 20, thereby removing impurities blocked on the filter screen inside the end head 20, making it easier to reuse the end head 20 in this operation.

[0086] End cleaning: The cleaning structure can clean the clogged end 20, thereby extending the service life of the end 20 and reducing the cost of use.

[0087] Example 2: Reference Figure 11 and Figure 12 This embodiment is an improvement on Example 1. A first synchronous pulley 47 is slidably connected to the top of the cleaning tank 40 via an annular slide rail, and the liquid inlet pipe 45 passes through the first synchronous pulley 47. A second synchronous pulley 51 is fixedly mounted on the outer wall of the output shaft of the drive motor 42. The second synchronous pulley 51 is connected to the first synchronous pulley 47 via a synchronous belt transmission. The diameter of the first synchronous pulley 47 is smaller than that of the second synchronous pulley 51. A placement tray 49 is fixedly mounted on the outer wall of the liquid inlet pipe 45, and a plurality of second hemispheres 50 are fixed to the bottom of the placement tray 49. A first hemisphere 48 is fixed to one side of the top of the first synchronous pulley 47, so that the first hemisphere 48 and the second hemisphere 50 are matched. A load-bearing block 52 is fixedly mounted on the outer wall of the liquid outlet pipe 46.

[0088] Specifically, when the drive motor 42 slowly rotates the rotating disk 41, the second synchronous wheel 51, the first synchronous wheel 47, and the timing belt cooperate to drive the first synchronous wheel 47 to rotate rapidly. The first synchronous wheel 47 drives the first hemisphere 48 to rotate. The contact between the first hemisphere 48 and the multiple second hemispheres 50 drives the liquid inlet pipe 45 and the liquid outlet pipe 46 to rotate to different angles. The provision of the bearing block 52 allows the liquid outlet pipe 46 to return to a vertical position when no external force is applied. This allows the liquid outlet pipe 46 to clean the interior of the end cap 20 from different angles, improving the flushing effect.

[0089] Through the specific implementation of the above parts, the integrated wound irrigation and suction device can effectively clean the end head 20, ensure the normal use of the end head 20 during the operation, and improve the safety and efficiency of the operation.

[0090] The method for using the wound irrigation and suction integrated device includes the following steps:

[0091] S1. Move the support body 1 to one side of the operating table, clamp the drain 17 in the C-shaped clamp 16, and move the dial plate 7 outward. The dial plate 7 drives the pin 6 out of the slot 9, releasing the brake between the support arm 3 and the support body 1. Then, manually push the support arm 3 up or down to the specified position. The pin 6 is reinserted into the slot 9 under the elastic force of the first spring 8, completing the height adjustment of the support arm 3.

[0092] S2. By rotating the rotating seat 12 and the sliding seat 11, rotating the rotating seat 12 and the cross bar 14, and cooperating with the damping universal joint 15 and the cross bar 14, the drain device 17 held in the C-shaped clamp 16 can be placed at different positions and angles, thereby completing the flushing and drainage operation without manually holding the drain device 17;

[0093] S3. During drainage, the pressing head 30 drives the driving rod 24 and the rotating cylinder 23 to rotate until the drainage channel 26 is aligned with the drainage connector 19. The alignment of the drainage channel 26 and the drainage connector 19 can be determined by the cooperation of the marking ball 31 and the marking plate 32. At this time, the negative pressure pump 36 is running, and the drainage cylinder 35 is in a negative pressure state. Then, the cooperation of the drain 17 and the end head 20 can draw the blood in the surgical area through the drainage connector 19 and the drainage channel 26 into the drainage cylinder 35, completing the drainage function.

[0094] S4. When flushing is required, the rotating cylinder 23 is rotated again, the flushing channel 25 is aligned with the flushing connector 18, and the booster pump 38 flushes the surgical site with the cleaning liquid in the storage box 37 through the connecting hose 39 and the drain 17, and the part of the drain 17 located below the rotating cylinder 23 can be flushed during flushing; when the drainage connector 19 and the drainage channel 26 need to be flushed, the rotating cylinder 23 is rotated again, the L-shaped channel 27 is aligned with the flushing connector 18, the pressing head 30 and the driving rod 24 are pressed, the sealing block 29 moves into the second sliding groove 28, and the sealing of the L-shaped channel 27 is released. The sealing plate 21 closes the second fixing ring 22, and the cleaning liquid enters the drain 17 through the L-shaped channel 27 and the drainage channel 26, and the cleaning liquid also enters the drainage cylinder 35 through the drainage connector 19, and then the drainage connector 19 and the drainage channel 26 can be flushed, which is convenient for the subsequent fine cleaning, sterilization and disinfection of the drain 17 as a whole;

[0095] S5. When the drainer 17 and the end head 20 drain for a long time, the filter screen in the end head 20 is clogged. In this case, the end head 20 is replaced and placed on the rotating disk 41. The drive motor 42 drives the rotating disk 41 to rotate slowly through the gearbox 43. When the drainer 17 is flushed later, the cleaning liquid in the connecting hose 39 is injected into the universal ball 44 and the liquid outlet pipe 46 through the connecting pipe to clean the end head 20. After cleaning, the end head 20 can be used again.

[0096] S6. In addition, when the driving motor 42 drives the rotating disk 41 to slide and rotate, the cooperation between the second synchronous wheel 51, the first synchronous wheel 47 and the synchronous belt drives the first synchronous wheel 47 to rotate, and the first synchronous wheel 47 drives the first hemisphere 48 to rotate. The contact between the first hemisphere 48 and the multiple second hemispheres 50 can drive the liquid inlet pipe 45 and the liquid outlet pipe 46 to rotate to different angles, so that the liquid outlet pipe 46 can clean the inside of the end head 20 from different angles. In addition, the design of the load-bearing block 52 can restore the liquid outlet pipe 46 to a vertical state when the first hemisphere 48 and the second hemisphere 50 are out of contact.

[0097] However, as is well known to those skilled in the art, the working principles and wiring methods of the gearbox 43, the boost pump 38 and the negative pressure pump 36 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

In actual implementation, the components may be appropriately configured and adjusted based on specific needs and actual conditions.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
