Description

Technical Field

[0001] The invention relates to the technical field of instruments for laparoscopic surgery, and in particular discloses an air leakage-proof vaginal plug for laparoscopic surgery. Background Art

[0002] Laparoscopic surgery is a minimally invasive surgical technique that involves inserting a laparoscope and related instruments through a small incision in the abdominal wall. It is mainly used for the diagnosis and treatment of abdominal and pelvic diseases.

[0003] During laparoscopic surgery, carbon dioxide gas needs to be injected into the patient's abdominal cavity to establish pneumoperitoneum and maintain a certain pelvic and abdominal pressure to ensure that the surgical field of view is fully exposed, thereby ensuring that the surgical operation proceeds smoothly. However, during the operation of removing the specimen through the vagina after hysterectomy, the pelvic and abdominal cavity is connected to the outside world through the vaginal stump, resulting in carbon dioxide gas leakage. This leakage phenomenon makes it difficult to maintain stable pneumoperitoneum pressure, which not only increases the difficulty of surgical operation and prolongs the operation time, but also the leaked carbon dioxide gas can reduce the air quality in the operating room, causing potential harm to the health of medical staff. The traditional method uses medical gloves to wrap multiple layers of sterile gauze to form a gauze roll, which is inserted through the vagina; however, due to the soft texture of the gauze roll, it is difficult to completely block the vagina, and it is easy to slip out of the vagina, the packing is not firm enough, and it is difficult to remove the packing device after surgery, which brings significant troubles to the surgical operation. For this reason, the present invention proposes an air leakage-proof vaginal packing device for laparoscopic surgery. Summary of the Invention

[0004] The purpose of the present invention is to solve the technical problems existing in the above-mentioned background technology. The present invention provides an air leakage-proof vaginal plug for laparoscopic surgery.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] An air leakage-proof vaginal plug for laparoscopic surgery, comprising:

[0007] The main airbag is made of biocompatible elastic material and has a cylindrical structure. The main airbag is hollow inside. The lower end of the main airbag is connected to a catheter, and the input end of the catheter is provided with a one-way inflation valve and a visual pressure indicator window;

[0008] The fixed support assembly includes a detachable external fixed plate and a retractable adjustment belt. The fixed plate is attached to the surface of the patient's perineum and is made of medical silicone. The retractable adjustment belt is arranged on the outside of the fixed plate and is used to be sleeved on the patient's thigh.

[0009] A release valve is integrated into the proximal end of the inflation and deflation catheter and is used to discharge the gas inside the catheter after disassembly;

[0010] The visual identification component includes a fluorescent positioning ring and a depth marking line at the proximal end of the catheter. The fluorescent positioning ring can emit green developing light under the illumination of a laparoscope cold light source to assist the surgeon in confirming the position of the obturator. The depth marking line is distributed longitudinally along the catheter in centimeters. The visual identification component cooperates with the pressure indicator window to achieve dual monitoring of the intraoperative status. When the airbag pressure exceeds 30 mmHg, the indicator window automatically changes to a red warning state.

[0011] Furthermore, the outer surface of the main airbag is provided with evenly distributed anti-slip micro-convex textures.

[0012] Furthermore, the main airbag has a low-profile curled shape in the uninflated state to facilitate insertion into the vaginal stump. After inflation, it can radially expand to a preset diameter and fit closely to the vaginal wall to form a physical sealing barrier.

[0013] Furthermore, the interior of the catheter is coated with a layer of medical-grade silicone to prevent gas leakage and enhance durability.

[0014] Furthermore, ventilation holes are provided at the edge of the fixing plate, and a pressure sensing pad is provided in the central area of ​​the fixing plate for real-time monitoring of the pressure condition of the perineum surface.

[0015] Furthermore, the surface of the telescopic adjustment belt is provided with scale markings and a Velcro structure to achieve precise control of tension to prevent displacement during surgery.

[0016] Furthermore, a knob is provided on the right side of the release valve, and the surface of the knob is provided with anti-slip grooves. Turning the knob clockwise can realize the instantaneous discharge of the gas in the main airbag, so that the main airbag returns to its initial volume within 3 seconds, so as to ensure efficient withdrawal after surgery.

[0017] Furthermore, a micro reflective sheet is integrated around the periphery of the fluorescent positioning ring to enhance the imaging effect under laparoscopy.

[0018] Furthermore, the lower portion of the depth marking line is set as a red segment for marking a safe operation threshold.

[0019] Furthermore, the release valve is equipped with a built-in safety lock mechanism, which requires pressing the knob and rotating it counterclockwise to unlock the valve, effectively preventing accidental deflation of the airbag due to accidental touch during surgery.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The radial expansion characteristics and anti-slip micro-convex texture of the main airbag of the present invention can closely fit the vaginal wall, forming a reliable physical sealing barrier, completely avoiding the slippage problem of traditional gauze rolls, improving the firmness of packing, and effectively preventing carbon dioxide gas leakage during laparoscopic surgery, maintaining stable pneumoperitoneum pressure, ensuring full exposure of the surgical field, significantly reducing the difficulty of surgical operation and shortening the operation time.

[0022] 2. The fixed support assembly of the present invention is combined with a telescopic adjustment belt to achieve precise fixation, prevent the device from shifting during surgery, and ensure operational stability. At the same time, the air vents and pressure sensing pad design reduce the patient's perineal surface pressure and improve comfort.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] See also Figure 1 - Figure 4 The present invention provides an air leakage-proof vaginal plug for laparoscopic surgery, comprising:

[0032] The main airbag 1 is made of biocompatible elastic material and has a cylindrical structure. The main airbag 1 is hollow inside. The lower end of the main airbag 1 is connected to a catheter 2. The input end of the catheter 2 is provided with a one-way inflation valve 3 and a visual pressure indication window 4. In actual use, the main airbag 1 is gently placed in the vaginal cavity. The doctor injects sterile gas into the main airbag 1 by operating the one-way inflation valve 3 to expand it to form a tight seal, effectively preventing gas leakage during laparoscopic surgery. The visual pressure indication window 4 monitors the pressure in the airbag in real time to ensure that the pressure value is maintained within a safe range to avoid tissue damage caused by excessive inflation.

[0033] The fixed support assembly includes a detachable external fixed plate 5 and a telescopic adjustment belt 6. The fixed plate 5 is attached to the patient's perineal surface and is made of medical silicone. The telescopic adjustment belt 6 is arranged on the outside of the fixed plate 5 and is used to be sleeved on the patient's thigh; after the main airbag 1 is inflated, its cylindrical structure evenly fits the vaginal wall, and combined with the fixed plate 5 and the telescopic adjustment belt 6 to achieve stable fixation.

[0034] The release valve 7 is integrated at the proximal end of the inflation and deflation catheter and is used to discharge the gas inside the catheter 2 after disassembly. After the operation, it is necessary to press the knob of the release valve 7 and rotate it counterclockwise to unlock the safety lock mechanism, slowly release the gas, and safely remove the obturator, effectively preventing the risk of accidental deflation during the entire process.

[0035] The visual identification component includes a fluorescent positioning ring 8 and a depth marking line 9 at the proximal end of the catheter. The fluorescent positioning ring 8 can emit green developing light under the illumination of a laparoscope cold light source to assist the surgeon in confirming the position of the obturator. The depth marking line 9 is distributed longitudinally along the catheter in centimeters. The visual identification component cooperates with the pressure indicator window 4 to achieve dual monitoring of the intraoperative status. When the airbag pressure exceeds 30 mmHg, the indicator window automatically changes to a red warning state; the fluorescent positioning ring 8 provides high-visibility guidance during the operation, which is convenient for rapid positioning. The red section of the depth marking line 9 serves as a visual warning, indicating the safe operation threshold, helping doctors to accurately control the insertion depth.

[0036] In this embodiment, preferably, the outer surface of the main airbag 1 is provided with a uniformly distributed anti-slip micro-convex texture; the anti-slip micro-convex texture can provide additional friction to prevent the airbag from accidentally sliding in the vagina, thereby enhancing the stability and anti-leakage effect of the plug; the texture design also optimizes the fit between the airbag and the vaginal wall, reduces the risk of displacement during surgery, and ensures the safety of the surgical operation.

[0037] In this embodiment, preferably, the main airbag 1 is in a low-profile curled shape in the uninflated state to facilitate insertion into the vaginal stump. After inflation, it can radially expand to a preset diameter, closely fitting the vaginal wall to form a physical sealing barrier. This setting can effectively prevent gas leakage during surgery and ensure the stability of pneumoperitoneum pressure. At the same time, the design facilitates rapid insertion and removal by medical staff, reduces the risk of tissue damage, and optimizes the fit with the vaginal wall through uniform expansion characteristics, further enhancing the anti-leakage effect.

[0038] In this embodiment, preferably, the interior of the catheter 2 is coated with a medical-grade silicone layer to prevent gas leakage and enhance durability; thereby effectively maintaining the sealing performance of the catheter 2 in a high-pressure surgical environment, avoiding gas leakage and causing pneumoperitoneum pressure fluctuations, and the silicone layer improves the flexibility and chemical corrosion resistance of the catheter 2, reduces wear during repeated use, ensures long-term reliable operation of the equipment, and reduces the risk of intraoperative infection.

[0039] In this embodiment, preferably, ventilation holes are provided at the edge of the fixed plate 5. The provision of the ventilation holes can effectively promote local skin ventilation, reduce moisture accumulation, and thus reduce the risk of skin pressure sores; and a pressure sensing pad is provided in the central area of ​​the fixed plate 5. The pressure sensing pad monitors the pressure data in real time through an integrated pressure sensor and transmits it to an external monitoring device, so that medical staff can dynamically adjust the position of the fixed plate 5 to avoid local tissue damage and optimize patient comfort; the combination of ventilation and pressure monitoring functions further improves the safety and operation accuracy during the operation, ensuring that the obturator maintains a stable fit during long-term surgery.

[0040] In this embodiment, preferably, the surface of the telescopic adjustment belt 6 is provided with scale markings and a Velcro structure to achieve precise control of the tension to prevent displacement during surgery; thereby, the stable fixation of the obturator during surgery can be effectively maintained to avoid loss of control of pneumoperitoneum pressure or interruption of surgery due to displacement, and the scale markings make it easy for medical staff to adjust the tension intuitively and accurately, and the Velcro structure ensures fast and reliable fitting, thereby improving operational convenience and patient comfort, and further optimizing surgical safety and equipment reliability.

[0041] In this embodiment, preferably, a knob is provided on the right side of the release valve 7, and the surface of the knob is provided with anti-slip grooves. Turning the knob clockwise can realize instantaneous discharge of the gas in the main airbag 1, so that the main airbag 1 returns to its initial volume within 3 seconds, to ensure efficient withdrawal after surgery; that is, it can improve surgical efficiency and reduce patient postoperative discomfort. The anti-slip grooves are used to enhance operational stability, prevent hand slippage during surgery, and ensure that medical staff can quickly and accurately perform gas discharge in an emergency, thereby optimizing the safety and reliability of the withdrawal process. This design, combined with the instantaneous discharge characteristics, effectively avoids secondary damage to the vaginal tissue during airbag withdrawal, and improves the patient's overall comfort and satisfaction with the use of the equipment.

[0042] In this embodiment, preferably, micro-reflective sheets are integrated around the periphery of the fluorescent positioning ring 8 to enhance the imaging effect under laparoscopy; that is, it can improve the accuracy and visibility of intraoperative positioning, ensure that the doctor can quickly identify the position of the obturator in a complex anatomical environment, thereby reducing the risk of operational errors, avoiding accidental injury to surrounding tissues, shortening the operation time, and optimizing the efficiency of the surgical process. The enhanced imaging effect helps to monitor the status of the obturator in real time, improve equipment reliability and patient safety.

[0043] In this embodiment, preferably, the lower portion of the depth marking line 9 is set as a red segment to indicate the safe operation threshold. This setting enables medical staff to intuitively identify the operating depth limit during surgery, thereby preventing tissue damage caused by excessive insertion, thereby improving the accuracy and safety of surgical operations, ensuring rapid judgment of the obturator position in complex anatomical environments, reducing the risk of accidental injury, shortening the operation time, and enhancing visibility to help monitor the device status in real time, optimize surgical process efficiency, and improve device reliability and patient comfort.

[0044] In this embodiment, preferably, the release valve 7 is equipped with a built-in safety lock mechanism, which requires pressing the knob and rotating it counterclockwise at the same time to unlock the operation, effectively preventing accidental deflation of the airbag due to accidental touch during the operation; thereby ensuring that the main airbag 1 remains in a stable inflated state throughout the operation, avoiding airbag leakage caused by misoperation during the operation, thereby greatly improving the safety of the surgical operation and reducing the risk of complications, that is, preventing packing failure caused by deflation.

[0045] The working principle and usage process of the present invention are as follows: When using the device, medical staff will assess the patient's condition and select an obturator of appropriate size. After confirming that the main airbag 1 is in an uninflated, low-profile curled state, it is gently inserted into the vagina axially to a predetermined depth. At this time, the depth mark line 9 on the catheter 2 can be used to refer to ensure that the insertion depth is within the safe threshold (above the red section). After insertion, the operator injects sterile gas (such as carbon dioxide) into the main airbag 1 through the one-way inflation valve 3, causing it to expand evenly radially until the visual pressure indicator window 4 shows that the pressure value reaches the preset safe range (usually 20-30 mmHg). At this time, the non-slip micro-convex texture of the airbag outer wall fits tightly against the vaginal wall, forming a physical sealing barrier.

[0046] During the inflation of the main airbag 1, medical staff need to continuously observe the pressure indicator window 4 to ensure that the pressure does not exceed the warning threshold of 30 mmHg; after the main airbag 1 is inflated and fixed, the detachable external fixation plate 5 is attached to the patient's perineal surface, and the telescopic adjustment belt 6 is wrapped around the patient's thigh. The tension is accurately adjusted according to the scale mark and the Velcro structure is used to reliably fix it to ensure that the entire device is stable and does not shift. The pressure sensing pad of the fixation plate 5 monitors the perineal pressure in real time and assists in adjustment to avoid excessive pressure on local tissues.

[0047] During the operation, under the irradiation of the laparoscope cold light source, the fluorescent positioning ring 8 emits conspicuous green fluorescence, and the micro reflector enhances its development effect, so as to facilitate the operator to clearly and quickly confirm the position of the tamponade device in the laparoscope field, and the pressure indication window 4 continuously monitors the pressure in the air bag, so as to double guarantee the stable and reliable sealing effect.

[0048] After the operation, the operator needs to press the knob of the release valve 7 and rotate the safety lock catch mechanism counterclockwise, at this time, the gas in the main air bag 1 is instantaneously discharged (about 3 seconds) through the release valve 7, the main air bag 1 quickly returns to the initial low profile coiled shape, and then the operator can gently and completely take out the tamponade device from the vagina.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
