Description

Technical Field

[0001] The present invention relates to the technical field of debridement devices, and in particular to a debridement device for general surgery. Background Art

[0002] In the field of general surgery, debridement is an indispensable and key step that directly affects the final outcome of the surgery and the patient's postoperative recovery process. Accurate and efficient debridement can completely remove all kinds of pollutants in the wound, such as dust and foreign matter, completely remove necrotic tissue, effectively kill bacteria, significantly reduce the risk of postoperative infection, and lay a solid foundation for the smooth healing of the wound. For example, in open fracture surgery, thorough debridement can prevent serious complications such as osteomyelitis; in abdominal trauma surgery, effective debridement can avoid life-threatening conditions such as sepsis caused by abdominal infection.

[0003] However, there are many problems that need to be solved with the traditional general surgery debridement devices currently on the market. In terms of the supply of cleaning fluid, only a single type of cleaning fluid is generally available, which is difficult to meet the diverse needs of different wounds at various stages. For superficial wounds with slight contamination, normal saline may be able to meet basic cleaning needs; but for deep burns with severe infections, or wounds contaminated by special pathogens such as Clostridium tetani and Clostridium perfringens, a single normal saline solution cannot achieve the goal of deep sterilization and thorough removal of pollutants. In actual clinical practice, wound types are rich and varied, ranging from simple skin abrasions to complex visceral ruptures, and debridement devices with a single cleaning fluid are obviously difficult to cope with.

[0004] Waste liquid treatment is also a major shortcoming of traditional debridement devices. Most devices cannot achieve simultaneous debridement and waste liquid extraction, resulting in a large amount of waste liquid accumulating around the wound during surgery. This not only seriously interferes with the surgical field of view and hinders the doctor's precise operation, but also easily causes secondary pollution, further increasing the risk of infection for patients. When extracting waste liquid, due to the lack of a structural design that effectively fits the wound, waste liquid leakage often occurs, which not only increases the risk of infection in the operating room, but also forces medical staff to spend extra energy on cleaning, affecting the efficiency of the operation. To this end, a general surgical debridement device is proposed. Summary of the invention

[0005] In view of this, an embodiment of the present invention hopes to provide a general surgical debridement device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0018] The present invention realizes storage of multiple cleaning liquids and classified collection of waste liquids by arranging multiple liquid storage chambers and waste liquid chambers in the liquid storage tank. The design of multi-channel infusion tubes, connecting tubes and multi-channel tubes, combined with precise control of electromagnetic valves, can quickly switch cleaning liquids to meet the needs of different wound debridement and improve the pertinence and effect of debridement.

[0038] Embodiment 1

[0039] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] like Figure 1-8As shown, an embodiment of the present invention provides a general surgical debridement device, including a frame 1 and a liquid storage tank 2 installed on the frame 1, and also including: a cleaning pipe 5, used to draw cleaning liquid from the liquid storage tank 2 and transport waste liquid to the liquid storage tank 2; a power mechanism 4, used to provide a drawing power for the cleaning pipe 5; wherein: the liquid storage tank 2 is provided with a plurality of liquid storage chambers 21 for storing different cleaning liquids and a waste liquid chamber 22 for storing waste liquid; the cleaning pipe 5 includes a second multi-channel pipe 53 for transporting cleaning liquid and waste liquid and a second multi-channel pipe 53 installed on the second multi-channel pipe 5 3, the inner side of the cleaning head 55 has a cavity, and the inner side of the cleaning head 55 is provided with a plurality of through holes 553 for drawing waste liquid, the through holes 553 are connected to the cavity, the cavity of the cleaning head 55 is connected with a connecting pipe 554, the second multi-channel tube 53 has a plurality of channels 1 for conveying cleaning liquid and a channel 2 for conveying waste liquid, the end of the connecting pipe 554 is inserted into the channel 2, by adopting the above scheme, a plurality of liquid storage chambers 21 are arranged in the liquid storage tank 2, and different cleaning liquids such as physiological saline, iodine tincture, and hydrogen peroxide can be stored respectively. Doctors can quickly switch the appropriate cleaning liquid according to the degree of contamination, infection type and healing stage of the wound, from simple abrasions and cuts to severe burns, infected wounds, etc., to meet the diverse debridement needs, greatly improve the debridement effect, cooperate with the specially established waste liquid chamber 22, and work in coordination with the cleaning pipe 5 to achieve debridement and waste liquid drawing synchronously. The cavity inside the cleaning head 55 is connected to a plurality of through holes 553 for drawing waste liquid, and is connected to the waste liquid channel 2 of the second multi-channel tube 53 through a connecting tube 554. During debridement, the waste liquid at the wound can be sucked into the waste liquid chamber 22 in time to avoid the accumulation of waste liquid around the wound, ensure a clear surgical field of view, and reduce the risk of secondary contamination. It is worth mentioning that a convex seal is provided on the outer side of the end of the connecting tube 554. This detail design greatly improves the sealing of the connection part. The convex seal can fit tightly against the inner wall of the waste liquid channel 2 of the second multi-channel tube 53, effectively preventing the leakage of waste liquid during the transmission process, ensuring that the waste liquid can be safely and stably transported to the waste liquid chamber of the liquid storage tank, providing reliable waste liquid treatment guarantee for the surgical debridement process, and further improving the working performance and use safety of the entire debridement device.

[0041] In this embodiment, specifically: Figure 3 and Figure 4The power mechanism 4 includes a shell 41 and a peristaltic pump 42 installed in the shell 41. The liquid inlet end 421 and the liquid outlet end 422 of each peristaltic pump 42 are respectively connected to the channels of the connecting tube 3 and the cleaning tube 5. The peristaltic pump 42 is a multi-channel peristaltic pump, and the model is Lange's T100 / T300 / T600 stepper motor integrated machine OEM peristaltic pump, which can be adapted to the DG multi-channel peristaltic pump head, providing a 1-8 channel solution, and can simultaneously and synchronously transmit multiple samples and reagents. In addition, in the present technical solution, an inlet end 421 of the multi-channel peristaltic pump is connected to the waste liquid pipeline of the cleaning head 55, and the liquid outlet end 422 is connected to the waste liquid pipeline of the connecting tube 3, so as to transport the inhaled waste liquid into the waste liquid chamber 22. In addition, the multi-channel peristaltic pump can provide a 1-8 channel solution, and can simultaneously and synchronously transmit multiple samples and reagents. In this device, in addition to being used for waste liquid transportation, it can also be used to transport different cleaning liquids. Each channel is independent of each other, and can control the delivery of different cleaning liquids respectively, and at the same time, the waste liquid is delivered to the waste liquid chamber 22 separately, thereby ensuring that the cleaning liquids and the cleaning liquid and the waste liquid will not mix with each other, and maintaining the purity and effectiveness of the cleaning liquid.

[0042] On the basis of the above scheme, the end of the cleaning head 55 has a fitting portion 56 for fitting the skin around the part to be debrided. The material of the cleaning head 55 is transparent, which is convenient for medical staff to observe the debriding situation in real time. The tail end of the cleaning head 55 is composed of an elastic part made of rubber or silicone material, which can fit closely to the part to be debrided. Under complex wound shapes and positions, it can also effectively reduce waste liquid leakage, reduce the risk of infection in the operating room, and reduce the cleaning burden of medical staff.

[0043] In this embodiment, specifically: a collar 54 is fixedly connected to the outer side of the second multi-channel tube 53, one side of the collar 54 has a plurality of plug-in grooves 541, and one side of the cleaning head 55 has a plurality of plug-in rods 551 adapted to the plug-in grooves 541. Figure 8 As shown, the plug-in rod 551 is installed on the cleaning head 552. First, in general surgery, in the face of different types of wounds, such as superficial abrasions, deep punctures, large-area lacerations, etc., cleaning heads with different functions and specifications are required to achieve the best debridement effect. Secondly, through the matching of the plug-in slot 541 of the collar 54 and the plug-in rod 551 of the cleaning head 55, medical staff can quickly and conveniently replace the cleaning head during the operation without complex tools or cumbersome operations, saving precious operation time and improving operation efficiency.

[0044] In this embodiment, specifically: the cleaning tube 5 further includes a tapered tube 52 connected to the second multi-channel tube 53 and a first multi-channel tube 51 connected to the tapered tube 52;

[0045] The number of conical tubes 52 is consistent with the number of channels of the second multichannel tube 53, the number of first multichannel tubes 51 is consistent with the number of channels of the second multichannel tube 53, the number of channels of the conical tubes 52 and the second multichannel tube 53 is consistent, and they are interconnected. Please refer to Figure 7 The special conical structure of the conical tube 52 helps to guide and accelerate the cleaning liquid. When the cleaning liquid flows from the second multi-channel tube 53 to the conical tube 52, due to the change in the tube diameter, the flow rate of the cleaning liquid will be adjusted, and it can be sprayed more forcefully to the wound site, thereby improving the cleaning effect. For some pollutants and necrotic tissues attached to the deep wound, they can be more effectively washed away. In addition, the first multi-channel tube 51 also has the same number of channels as the second multi-channel tube 53 and is connected, so it can serve as a "transit hub". After the multi-channel peristaltic pump draws different cleaning liquids from different liquid storage chambers 21, they are initially integrated and distributed through the first multi-channel tube 51, and then transported to the cleaning head through the conical tube 52 and the second multi-channel tube 53. In this way, the delivery order and proportion of different cleaning liquids can be controlled more flexibly. For example, in the case of mixed infected wounds, two different sterilizing cleaning liquids can be delivered simultaneously in a specific proportion to enhance the debridement effect.

[0046] In the present embodiment, specifically: the top of the liquid storage tank 2 has a plurality of liquid inlet pipes 211 for conveying cleaning fluid into the liquid storage chamber 21, and the bottom of the liquid storage tank 2 has a plurality of discharge pipes for discharging the liquid in the liquid storage chamber 21. Before the operation, medical staff can inject different types of cleaning fluids into the corresponding liquid storage chambers through these liquid inlet pipes 211, such as physiological saline, iodine solution, etc., to ensure that the liquid storage tank 2 can supply a variety of cleaning fluids at any time. During the operation, if a certain cleaning fluid is consumed more, it can also be replenished from the liquid inlet pipe 211 in time to avoid affecting the progress of debridement due to insufficient cleaning fluid, and ensure the continuity of debridement work. The discharge pipe at the bottom of the liquid storage tank 2 is used to discharge the liquid in the liquid storage chamber 21. After the operation or during regular maintenance, the remaining cleaning fluid in the liquid storage chamber 21 can be emptied through the discharge pipe, which is convenient for comprehensive cleaning and disinfection of the liquid storage chamber 21. It is helpful to maintain the hygiene inside the liquid storage chamber, prevent bacteria from breeding and residual cleaning fluid from deteriorating, and ensure the quality and safety of the cleaning fluid when it is used next time.

[0047] In this embodiment, specifically: the top of the liquid storage tank 2 is connected with a pressure relief valve 221, the pressure relief valve 221 is connected with the waste liquid chamber 22, and the top of the pressure relief valve 221 is threadedly connected with a rubber sleeve 222. During the operation, as the waste liquid is continuously collected into the waste liquid chamber 22, the pressure in the chamber will gradually increase. If the pressure is too high, the liquid storage tank may be deformed or even ruptured, affecting the normal use of the device, and may also cause waste liquid leakage and pollution. The pressure relief valve 221 is connected with the waste liquid chamber 22. When the pressure in the waste liquid chamber 22 exceeds the safety value, the pressure relief valve 221 automatically opens to discharge the excess gas, so that the pressure in the chamber is kept within a safe range, ensuring the safe and stable operation of the liquid storage tank 2 and the entire device. The rubber sleeve 222 threadedly connected to the top of the pressure relief valve 221 tightly covers the opening of the pressure relief valve under normal circumstances. It is like a barrier to prevent external dust, bacteria and other pollutants from entering the waste liquid chamber 22. The surgical environment has extremely high requirements for sterility. If external pollutants enter the waste liquid chamber, they may cause secondary pollution with the flow of waste liquid, threatening the healing of the patient's wound. The rubber sleeve 222 effectively avoids this situation and maintains a relatively clean environment in the waste liquid chamber. The bottom end of the rubber sleeve 222 has a rigid connector, and is connected to the pressure relief valve 221 through the rigid connector. The pressure relief valve 221 has a one-way valve inside, and the rubber sleeve 222 is connected to the top of the pressure relief valve 221 through threads. The connection method is simple and stable. When the pressure relief valve 221 needs to be inspected, cleaned or maintained, medical staff can easily unscrew the rubber sleeve and tighten it to reset it after the operation is completed. This design does not affect the normal function of the pressure relief valve, but also provides convenience for the daily maintenance of the device, reducing the maintenance cost and difficulty.

[0048] In this embodiment, specifically: the top of the liquid storage tank 2 is connected with a plurality of infusion tubes 23, and each infusion tube 23 is installed with a solenoid valve, the infusion tube 23 is connected with the connecting tube 3, the connecting tube 3 has a plurality of channels, respectively connected to different infusion tubes 23, and the plurality of infusion tubes 23 are respectively connected to different liquid storage chambers 21 of the liquid storage tank 2, and the solenoid valve on each infusion tube 23 can be independently controlled. The doctor can accurately select and deliver the required cleaning solution by controlling the opening and closing of the solenoid valve according to the specific conditions of the wound, such as the degree of contamination, the type of infection, etc. For example, for a slightly contaminated wound, the solenoid valve of the infusion tube that delivers physiological saline is opened; for an infected wound, the solenoid valve of the infusion tube that delivers a sterilizing cleaning solution such as iodine is opened to ensure that the most suitable cleaning solution is used during the debridement process and improve the debridement effect. The multi-channel design of the connecting tube 3 makes the cleaning solutions delivered by different infusion tubes 23 independent of each other and will not mix. Each channel is connected to a different infusion tube 23. Even if multiple infusion tubes are opened at the same time, the cleaning liquid will flow in each channel to maintain the purity and effectiveness of the cleaning liquid, ensuring that each cleaning liquid can play its specific cleaning role and avoiding problems such as changes in composition and reduced effect due to mixing of the cleaning liquid.

[0049] More specifically: a control panel 6 is installed on the frame 1, which is used to control the start and close of the solenoid valves on different infusion tubes 23. Medical staff do not need to directly operate the solenoid valves on the infusion tubes 23 during the operation. They only need to operate on the control panel 6 to quickly control the start and close of the solenoid valves on different infusion tubes 23. This makes the switching operation of the cleaning fluid more convenient and saves precious surgical time. For example, when the doctor finds that the wound needs to be replaced with the cleaning fluid, he can directly select the corresponding button on the control panel 6 to complete the switching of the cleaning fluid, avoiding the trouble of finding and operating a single solenoid valve in a complex device.

[0050] In this embodiment, starting from the infusion tube 23 on the liquid storage tank 2, the outflow order of the cleaning liquid is the connecting tube 3, the first multi-channel tube 51, the tapered tube 52, the second multi-channel tube 53 and the cleaning head 55, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 It can be seen that the connecting tube 3 includes a conical tube 2 connected to different infusion tubes 23, and its bottom diameter is larger than the top diameter (see Figure 5 ), that is, according to the infusion diameter from large to small, they are infusion tube 23, connecting tube 3, first multi-channel tube 51, tapered tube 52 and second multi-channel tube 53. According to the principle of fluid mechanics, under the condition of constant flow rate, the reduction of tube diameter will speed up the flow rate of fluid. The cleaning liquid flows from the infusion tube 23 with a larger diameter into the connecting tube 3 with a smaller diameter, and then into the thinner first multi-channel tube 51, etc., and the flow rate gradually increases, and finally sprays out from the cleaning head 55 at a higher speed, which enhances the flushing force on the wound, helps to more effectively remove pollutants, necrotic tissues, etc. at the wound, and improves the debridement effect. At the same time, this change in tube diameter can also maintain the pressure stability of the cleaning liquid during the transportation process, and ensure that the cleaning liquid flows out continuously and stably. The inflow order of the waste liquid is the second multi-channel tube 53, tapered tube 52, first multi-channel tube 51, connecting tube 3, infusion tube 23. The waste liquid starts from the second multi-channel tube 53 and flows in the order of tapered tube 52, first multi-channel tube 51, connecting tube 3, and infusion tube 23. As the diameter of the pipe gradually increases, according to the principles of fluid mechanics, the flow rate will gradually slow down and the pressure will gradually increase. This forms a pressure difference, so that the waste liquid can be smoothly sucked back from the wound under the action of the pressure difference, and finally flow into the waste liquid chamber 22 through various pipes, realizing efficient waste liquid collection. The waste liquid flows in the gradually thickening pipe, which can reduce the residual waste liquid in the pipe. As the pipe diameter increases, the contact area between the waste liquid and the pipe wall is relatively reduced, the friction force is reduced, the waste liquid is easier to flow, the possibility of waste liquid adhering to the inner wall of the pipe is reduced, and the risk of bacterial growth and pipe blockage due to residual waste liquid is reduced, thereby ensuring the cleanliness and normal operation of the device.

[0051] In the general surgical debridement device of the present invention, in order to improve the accuracy and safety of the debridement operation, detection structures such as a flow meter and a pressure gauge may be further provided and connected to the control panel 6 .

[0052] On the cleaning liquid delivery path, flow meters are installed at key positions such as the first multi-channel tube 51 and the second multi-channel tube 53 to monitor the flow of the cleaning liquid in real time. Medical staff can intuitively obtain these data through the control panel and accurately understand the output of the cleaning liquid at different times. For example, for different types of wounds, the appropriate cleaning liquid flow rate can be set based on clinical experience. When the actual flow rate deviates, the speed of the peristaltic pump 42 is adjusted on the control panel in time to ensure that the wound is properly flushed, so as to avoid insufficient supply of cleaning liquid affecting the debridement effect and prevent excessive flow from causing unnecessary impact and damage to the wound.

[0053] At the same time, it is of great significance to install pressure gauges in the connecting pipe 3, the waste liquid chamber 22 and other parts. During the waste liquid recovery process, by monitoring the pressure in the connecting pipe 3, it can be discovered in time whether the waste liquid is transported smoothly. If the pressure rises abnormally, it may mean that the pipeline is blocked. Medical staff can respond quickly on the control panel 6, suspend the operation of the device, check and solve the blockage problem, and prevent the waste liquid from flowing back and causing secondary pollution. For the waste liquid chamber 22, the pressure gauge can feedback the pressure in the chamber in real time. When the pressure approaches or reaches the safety upper limit, an alarm can be issued on the control panel to remind medical staff to handle the waste liquid in time to avoid damage to the liquid storage tank or leakage of waste liquid due to excessive pressure, and ensure the safe and stable operation of the device.

[0054] Embodiment 2

[0055] The present invention also provides another structure of the cleaning head 55, referring to Fig. 9 A sealing portion 57 is installed on the cleaning head 55. When the waste liquid channel needs to be cleaned, the sealing portion 57 can effectively prevent the cleaning liquid from flowing out from the normal cleaning outlet, but guide the cleaning liquid directly into the waste liquid channel, and directly enter the connecting pipe 554 through the through hole 553, so as to comprehensively clean the waste liquid channel, prevent the residual waste liquid from breeding bacteria, ensure the cleanliness of the device, avoid affecting the subsequent debridement effect due to channel contamination, and improve the practicality and safety of the device.

[0056] When the present invention is working: Preparation stage: Medical staff first inject different types of cleaning liquids, such as physiological saline, iodine solution, etc., into each liquid storage cavity 21 through the liquid inlet pipe 211 at the top of the liquid storage tank 2 according to the expected needs of the operation. At the same time, check the state of the peristaltic pump 42 in the power mechanism 4 to ensure its normal operation, and check whether each pipeline connection is tight and leak-free. Then place the debridement device in a suitable position to ensure that the frame 1 is stable and convenient for surgical operation.

[0057] Debridement stage: The doctor controls the start and close of the solenoid valve on the infusion tube 23 through the control panel 6 on the frame 1 according to the actual condition of the wound. For example, for a slightly contaminated wound, the solenoid valve of the infusion tube 23 for delivering saline is first opened. At this time, the cleaning liquid passes through the connecting tube 3, the first multi-channel tube 51, the tapered tube 52, the second multi-channel tube 53 in sequence, and finally flows out from the cleaning head 55 to perform a preliminary flushing of the wound.

[0058] During the flow of the cleaning liquid, the conical tube 2 in the connecting tube 3, whose bottom diameter is larger than the top diameter, will evenly distribute the cleaning liquid to each channel, and then pass through the first multi-channel tube 51, the conical tube 52 and the second multi-channel tube 53 with gradually decreasing tube diameters, thereby accelerating the flow rate of the cleaning liquid and enhancing the flushing effect on the wound.

[0059] Waste liquid recovery stage: As the cleaning proceeds, the waste liquid generated at the wound enters the cavity of the cleaning head 55 through the multiple through holes 553 opened on the inner side of the cleaning head 55, and then flows into the waste liquid channel of the second multi-channel tube 53 through the connecting tube 554. Due to the action of the peristaltic pump 42 in the power mechanism 4, the waste liquid passes through the tapered tube 52, the first multi-channel tube 51, the connecting tube 3 in sequence, and finally flows into the waste liquid cavity 22 of the liquid storage tank 2 through the infusion tube 23.

[0060] In this process, the diameter of the pipe through which the waste liquid flows gradually increases, and the pressure difference is formed by utilizing the principle of fluid mechanics, so that the waste liquid can be smoothly sucked back and the waste liquid residue in the pipe is reduced. If a cleaning head 55 with a sealing portion 57 is used, the sealing portion 57 will prevent the cleaning liquid from flowing out, ensuring that the waste liquid can only enter the connecting pipe 554 through the through hole 553, preventing the cleaning liquid from mixing with the waste liquid, and improving the waste liquid collection efficiency.

[0061] Switching cleaning fluid stage: If the wound condition is found to have changed during the debridement process and the cleaning fluid needs to be replaced, the doctor will again close the solenoid valve of the current infusion tube 23 through the control panel 6 and open the solenoid valve of another corresponding infusion tube 23, so that the new cleaning fluid is delivered to the wound along the established path and the debridement work continues.

[0062] Ending stage: After the surgical debridement is completed, the peristaltic pump 42 in the power mechanism 4 is turned off to stop the delivery of the cleaning liquid and the recovery of the waste liquid. The remaining cleaning liquid in the liquid storage chamber 21 is drained through the discharge pipe at the bottom of the liquid storage tank 2 to clean and disinfect the liquid storage tank 2. At the same time, the waste liquid in the waste liquid chamber 22 is cleaned, and the entire device is sorted and maintained to prepare for the next use.

[0063] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
