Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a peritoneum protection device for laparoscopic total extraperitoneal inguinal hernia repair. Background Art

[0002] Inguinal hernia refers to an extra-abdominal hernia that occurs in the groin area, that is, organs or tissues in the abdominal cavity protrude through the defect in the groin area of ​​the abdominal wall. The occurrence of inguinal hernia is mainly related to reduced abdominal wall strength and increased abdominal pressure, including congenital abdominal wall hypoplasia or defects, such as patent processus vaginalis, inguinal dysplasia, etc., and acquired abdominal wall muscle atrophy or weakness, such as the elderly, obese people, malnourished people, etc.

[0003] The typical symptom of an inguinal hernia is a protruding, reducible mass in the groin area. Initially, the mass is small and may only be accompanied by a slight feeling of heaviness. As the mass gradually grows, the patient will experience pain. In addition, inguinal hernia may also cause the following symptoms:

[0004] Abdominal distension and pain, a feeling of heaviness, as well as digestive tract symptoms such as nausea and vomiting.

[0005] If the hernia contents become incarcerated or strangulated, it can cause intestinal obstruction, leading to symptoms such as severe abdominal pain and bloating.

[0006] Systemic symptoms, such as fever, low blood pressure, coma, etc., are usually caused by ischemia, necrosis and infection of the hernia contents.

[0007] The treatment of inguinal hernia mainly includes two methods: non-surgical treatment and surgical treatment. Among them, surgical treatment is the main treatment method for inguinal hernia. Common surgical methods include traditional herniorrhaphy, tension-free herniorrhaphy, and laparoscopic herniorrhaphy (TEP). Among them, due to the advantages of laparoscopic herniorrhaphy such as less trauma and fast postoperative recovery, it is currently the mainstream surgical method for inguinal hernia. Common surgical methods for laparoscopic tension-free inguinal hernia repair include transperitoneal preperitoneal repair (TAPP), completely extraperitoneal preperitoneal repair (TEP), intraperitoneal patch repair (IPOM), etc. Since TEP is a completely extraperitoneal repair and does not enter the abdominal cavity, it has less impact on abdominal organs and has been increasingly widely used. The purpose of the operation is to return the hernia contents to the abdominal cavity and repair the abdominal wall defect to prevent the recurrence of hernia. Generally, some devices are used during the operation to prop up the patient's abdominal wall to provide the doctor with operating space. At the same time, a certain distance is formed between the preperitoneal structure and the abdominal wall, so that the laparoscope lens can more clearly observe the shape, position and adjacent relationship of the preperitoneal structure after entering the abdominal cavity. Some existing peritoneal support devices for laparoscopic total extraperitoneal inguinal hernia repair may block the movement path of subsequent surgical instruments when the position of the device is relatively close to the position of the inguinal hernia when separating the abdominal wall and peritoneum, thereby reducing the efficiency and safety of the operation.

[0008] Therefore, the present invention proposes a peritoneal protection device for laparoscopic total extraperitoneal inguinal hernia repair, which reduces the possibility of affecting the normal operation of subsequent surgical instruments when the device support position is relatively close to the position of the inguinal hernia. Summary of the invention

[0009] To solve the above problems, the present invention provides a peritoneal protection device for laparoscopic total extraperitoneal inguinal hernia repair, which reduces the possibility of affecting the normal operation of subsequent surgical instruments when the device support position is relatively close to the position of the inguinal hernia.

[0010] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a peritoneal protection device for laparoscopic total extraperitoneal inguinal hernia repair, comprising a holding shell, a pipe assembly for placing a laparoscope and positioning it at a supporting position is fixedly connected to the bottom of the holding shell, a first airbag is fixedly connected to the bottom of the pipe assembly and the first airbag is hollow after expansion, a second airbag located inside the first airbag is fixedly connected to the surface of the pipe assembly and the second airbag is hollow after expansion, a movable through groove is provided on the surface of the second airbag, a monitoring port connected to the pipe assembly and used for placing a laparoscope is provided on the top of the holding shell, a driving assembly for driving the pipe assembly to rotate is installed inside the holding shell, and an air supply assembly for inflating and deflating the first airbag and the second airbag is fixedly connected to the outer wall of the holding shell.

[0011] Principle of the basic solution: Move the first airbag and the second airbag to the patient's preperitoneal space through the pipeline assembly, and then use the air supply assembly to inflate the first airbag and the second airbag. At the same time, place the laparoscope in the pipeline assembly through the monitoring port, and use the laparoscope to observe the position of the pipeline assembly while slightly adjusting the position of the pipeline assembly, while observing the inflation status of the first airbag and the second airbag; after the first airbag and the second airbag are completely inflated, use the laparoscope to observe whether the hollow parts of the first airbag and the second airbag are aligned with the relative position of the inguinal hernia. If not, start the drive assembly, rotate the pipeline assembly, rotate the second airbag, and rotate the holes on its surface to the movement path of the surgical instrument, thereby supporting the patient's abdominal wall while providing operating space for subsequent surgery, reducing the possibility of the device affecting the movement of the surgical instrument after positioning and supporting.

[0012] The above scheme has the following beneficial effects:

[0013] 1. Compared with the prior art, when separating the abdominal wall and peritoneum, the current device is easy to interfere with the movement path of the subsequent doctor's operation of the surgical instrument when the device is relatively close to the position of the inguinal hernia, that is, it reduces the surgical space and thus affects the efficiency of the operation; this solution, through the first airbag and the second airbag and the hollow design of the two airbags, can provide stable support for the patient's abdominal wall after inflation, while ensuring that there is sufficient space at the surgical incision, and the surgical instruments can pass through the hollow parts of the two airbags to reach the target position for surgery, which reduces the impact of the device on the movement of the surgical instruments after positioning and supporting, and improves the flexibility and safety of the operation.

[0014] 2. In this solution, the laparoscope can be conveniently placed and real-time monitoring can be performed through the monitoring port and pipeline assembly on the holding shell. The doctor can visually observe the inflation status of the airbag and the position of the pipeline assembly, thereby making precise position adjustments to ensure the accuracy and reliability of the operation.

[0015] 3. In this solution, the design of the drive assembly and the air supply assembly allows the doctor to control the inflation and deflation of the airbag and the rotation of the pipeline assembly, which not only simplifies the surgical operation process to improve surgical efficiency and reduce surgical risks, but also adjusts the rotation angle of the pipeline assembly based on laparoscopic observation to facilitate the normal progress of subsequent operations.

[0016] 4. This solution uses a dual airbag design of a first airbag and a second airbag. When a doctor accidentally damages one airbag during operation, the other airbag can also play a supporting role, thereby preventing one airbag from being unable to play a supporting role after being damaged, affecting the surgical effect.

[0017] Furthermore, the pipeline assembly includes a first pipeline and a second pipeline respectively fixedly connected to the bottom end of the holding shell, the first pipeline and the second pipeline are located on the same central axis and the inner diameter of the first pipeline is consistent with the outer diameter of the second pipeline, the inner wall of the holding shell is slidably fitted with a rotating pipeline, one end of the rotating pipeline passes through the holding shell and the first pipeline in sequence, and the rotating pipeline is slidably fitted with the first pipeline and the second pipeline; the first airbag is fixedly connected to the bottom of the second pipeline at one end away from the first pipeline.

[0018] Beneficial effects: Through the nested design of the first pipe and the second pipe, and the sliding cooperation between the rotating pipe and the two, the stability and reliability of the pipe assembly during the operation are ensured, which not only enhances the overall structural strength of the device, but also enables the rotating pipe to rotate smoothly, thereby adjusting the second airbag fixed on the surface of the rotating pipe so that the movable groove on its surface corresponds to the surgical operation incision, thereby providing more flexibility and accuracy for the surgical operation.

[0019] The consistent design of the inner diameter of the first pipe and the outer diameter of the second pipe enables the pipe assembly to maximize space utilization while maintaining compactness, which helps to reduce the device's occupation of the patient's abdominal cavity, reduce discomfort during surgery, and provide more operating space for surgical instruments. At the same time, since the first pipe and the second pipe are located on the same central axis and the rotating pipe can smoothly pass through them, the laparoscope can be easily placed in the pipe assembly through the monitoring port, which not only simplifies the surgical operation process, but also allows doctors to more intuitively observe the situation in the surgical area, improving the accuracy and safety of the surgery.

[0020] Furthermore, the driving assembly includes a driving motor fixedly connected to the inside of the holding shell, the output shaft of the driving motor is coaxially fixedly connected to a main gear, the main gear is meshed with a rotating pipe, the rotating pipe is meshed with a secondary gear rotatably connected to the inside of the holding shell, and a driving button electrically connected to the driving motor is installed on the outer surface of the holding shell.

[0021] Beneficial effects: Through the coaxial fixed connection between the drive motor and the main gear, and the meshing of the main gear and the rotating pipe, accurate and stable drive control of the rotating pipe is achieved, ensuring that the doctor can accurately adjust the position and posture of the second airbag during the operation, thereby meeting the needs of the surgical operation. At the same time, the addition of the sub-gear further enhances the transmission efficiency of the gear, which meshes with the rotating pipe. By increasing the transmission ratio, the drive motor can more easily drive the rotating pipe to rotate, which not only improves the efficiency of the operation, but also reduces the energy consumption and noise of the drive motor, providing a more comfortable surgical environment for patients and doctors.

[0022] In addition, the driving button installed on the outer surface of the grip shell allows the doctor to easily control the start and stop of the driving motor, simplifying the surgical operation process, allowing the doctor to focus more on the operation itself, and improving the concentration and safety of the operation.

[0023] Furthermore, the air supply component includes a rubber inflatable bag, one end of which is connected to an air supply pipe, a three-way valve is installed on the air supply pipe, and two output ends of the three-way valve are respectively connected to the first air bag and the second air bag.

[0024] Beneficial effects: A rubber inflatable bag is used as the air source, which is connected to the three-way valve through an air supply tube to achieve independent or simultaneous inflation control of the first and second air bags. Doctors can flexibly choose to inflate a single air bag or two air bags according to surgical needs to meet different surgical needs. The design of the three-way valve allows doctors to easily switch inflation targets without changing the air source or adjusting the pipeline connection, which not only simplifies the operation process, but also reduces time waste during surgery and improves the efficiency and safety of surgery.

[0025] Furthermore, a deflation valve is installed at one end of the inflatable bag.

[0026] Beneficial effect: The addition of the deflation valve allows the doctor to quickly discharge the gas in the first airbag and the second airbag when necessary, thereby achieving rapid contraction of the airbag. At the end of the operation, it can greatly save operation time and improve surgical efficiency.

[0027] By quickly deflation and re-inflation, doctors can flexibly adjust the state of the airbag according to the progress of the operation, providing more operating space and flexibility for the operation, helping doctors to better deal with emergencies during the operation and ensure the smooth progress of the operation. At the same time, the existence of the deflation valve also increases the safety of the operation. In an emergency, such as an accidental rupture of the airbag or excessive inflation causing discomfort to the patient, the doctor can quickly release the gas through the deflation valve to reduce the risk of the operation.

[0028] Furthermore, the first airbag and the second airbag are both made of transparent rubber material.

[0029] Beneficial effects: The transparent rubber material allows doctors to visually observe the inflation state and shape changes inside the airbag, which helps doctors accurately judge whether the airbag has achieved the expected support effect during surgery, so as to adjust the inflation volume of the airbag in time to ensure the smooth progress of the operation. The transparent material allows doctors to clearly see the contact between the airbag and the patient's abdominal wall, avoiding damage to the patient caused by excessive inflation or improper position of the airbag. At the same time, doctors can also promptly discover and deal with any potential safety hazards to ensure the safety of the operation.

[0030] Furthermore, the second pipe is made of transparent material.

[0031] Beneficial effects: The transparent second tube allows doctors to clearly see the situation inside the tube, including the placement of the laparoscope, the inflation status of the airbag, and the passage of surgical instruments, etc., which helps doctors make more accurate judgments and decisions during the operation and improves the accuracy and safety of the operation. Through the transparent tube, doctors can intuitively observe the situation in the surgical operation area, so as to more flexibly adjust the position and angle of the surgical instruments, which helps to reduce blind spots and errors during the operation and improve the efficiency and success rate of the operation.

[0032] Furthermore, a locking nut is threadedly connected to the outer surface of the holding shell, and the connection point between the monitoring port and the second pipeline is located within the movement track of the locking nut.

[0033] Beneficial effects: The design of the locking nut allows the doctor to easily adjust and fix the position of the laparoscope between the monitoring port and the second pipe, thereby facilitating observation of the status of the device and making timely adjustments, while also reducing the burden on the operator.

[0034] Furthermore, the first airbag and the second airbag are both ellipsoidal in shape after expansion.

[0035] Beneficial effects: The ellipsoidal airbag shape can better adapt to the complex environment in the abdominal cavity, provide uniform and stable support for patients, help reduce discomfort during surgery, and improve the comfort and safety of surgery. Compared with other shapes (such as spheres, cylinders, etc.), the ellipsoidal airbag has a larger contact area, which can better disperse pressure and reduce the risk of damage to the patient's abdominal wall. At the same time, the larger contact area also helps to improve the sealing performance of the airbag and prevent gas or liquid leakage.

[0036] Furthermore, the outer surface of the grip shell is provided with anti-slip patterns.

[0037] Beneficial effects: The anti-slip pattern design enables doctors to hold the device more stably during surgery, avoiding operational errors caused by hand slippage or hand fatigue, helping to ensure the smooth progress of surgery and the safety of patients. At the same time, it can increase the friction between the hand and the grip shell, allowing doctors to maintain a grip posture more easily during long surgeries, reducing hand fatigue and discomfort.

[0046] The following is further described in detail through specific implementation methods:

[0047] Example:

[0048] As attached Figure 1 , Figure 2 and Figure 3Shown is a peritoneal protection device for laparoscopic total extraperitoneal inguinal hernia repair, including a gripping shell 1. Generally, in laparoscopic surgery, doctors need to operate various instruments for a long time and with high precision. The gripping shell 1 is the direct contact point between the doctor and the device, and its stability and comfort are extremely important. Therefore, anti-slip grooves are provided on the outer surface of the gripping shell 1 to increase the friction between the doctor's hand and the gripping shell 1, so that the doctor can hold the device stably even if the hand is tired or encounters other lubricating substances during the operation, avoiding operational errors caused by hand slippage. A pipeline assembly for placing the laparoscope and positioning it to a supporting position is fixedly connected to the bottom end of the gripping shell 1. A first airbag 6 is fixedly connected to the bottom of the pipeline assembly, and the first airbag 6 is hollow after expansion. A second airbag 7 located inside the first airbag 6 is fixedly connected to the surface of the pipeline assembly, and the second airbag 7 is hollow after expansion ( Figure 1 ), at the same time, the environment in the preperitoneal space is complex, in order to better fit the curves and uneven parts in the abdominal cavity and provide uniform and stable support for the patient, the first airbag 6 and the second airbag 7 are both ellipsoidal in shape after expansion, and the hollow airbag ( Figure 1 ) are larger than the width and length of the second airbag 7 after expansion, ensuring that surgical instruments can smoothly pass through the hollow parts of the first airbag 6 and the second airbag 7 in sequence, thereby ensuring that sufficient effective operating space is provided for subsequent operations; the surface of the second airbag 7 is provided with a movable through groove, the top of the holding shell 1 is provided with a monitoring port 2 which is connected to the pipeline assembly and is used to place a laparoscope, a driving assembly for driving the pipeline assembly to rotate is installed inside the holding shell 1, and an air supply assembly for inflating and deflating the first airbag 6 and the second airbag 7 is fixedly connected to the outer wall of the holding shell 1. A locking nut 14 is threadedly connected to the outer surface of the holding shell 1, and the connection between the monitoring port 2 and the second pipeline 8 is located within the movement trajectory of the locking nut 14, so that the locking nut 14 can be rotated to lock the laparoscope in a suitable position in the second pipeline 8 according to the real-time needs of the operation, for example, when adjusting the second airbag 7, the laparoscope is fixed in the middle of the second pipeline 8; and when performing a surgical operation, the laparoscope is fixed inside the second pipeline 8 near its bottom end to observe the surgical situation in real time, providing reliable real-time images for doctors.

[0049] The pipeline assembly includes a first pipeline 5 and a second pipeline 8 which are respectively integrally formed at the bottom end of the grip shell 1. The first pipeline 5 and the second pipeline 8 are located on the same central axis and the inner diameter of the first pipeline 5 is consistent with the outer diameter of the second pipeline 8. The inner wall of the grip shell 1 is slidably matched with a rotating pipeline 9 and a portion of the surface of the rotating pipeline 9 located inside the grip shell 1 is integrally formed with a plurality of teeth. One end of the rotating pipeline 9 passes through the grip shell 1 and the first pipeline 5 in sequence, and the rotating pipeline 9 is slidably matched with the first pipeline 5 and the second pipeline 8; the right end of the first airbag 6 is bonded to the bottom of the second pipeline 8 ( Figure 1 ); The second airbag 7 is bonded to the surface of the rotating pipe 9.

[0050] The driving assembly includes a driving motor 10 fixedly connected to the inside of the holding shell 1 by screws, and the output shaft of the driving motor 10 is coaxially keyed with a main gear 11, the main gear 11 is meshed with teeth on the surface of the rotating pipe 9, and the rotating pipe 9 is meshed with a sub-gear 12 rotatably connected to the inside of the holding shell 1 to ensure the normal rotation of the rotating pipe 9, and a driving button 13 electrically connected to the driving motor 10 is installed on the outer surface of the holding shell 1.

[0051] The air supply assembly includes a rubber inflatable bag 4, one end of which is connected to an air supply pipe, on which a three-way valve 3 is installed. The two output ends of the three-way valve 3 are respectively connected to the first air bag 6 and the second air bag 7. One end of the inflatable bag 4 is installed with an air release valve to ensure rapid resetting of the device after the operation.

[0052] The first airbag 6 and the second airbag 7 are both made of transparent rubber, and the good elastic deformation characteristics of rubber are used to ensure that the first airbag 6 and the second airbag 7 can be expanded according to a predetermined shape; the second pipe 8 is made of a transparent material, and materials such as polyvinyl chloride (PVC), polycarbonate (PC) and thermoplastic polyurethane (TPU) can be selected. Since the first airbag 6, the second airbag 7 and the second pipe 8 are transparent, when the laparoscope reaches the position where the second airbag 7 is located, it can sequentially monitor the patient's abdominal cavity through the second pipe 8, the second airbag 7 and the first airbag 6 in real time.

[0053] The specific implementation process is as follows: Usually, laparoscopic total extraperitoneal inguinal hernia repair requires the expansion of the preperitoneal space to provide effective space for subsequent laparoscopy and subsequent surgery, thereby reducing unnecessary damage to the peritoneum by surgical tools during the operation. In general, the location of hernias in different patients will vary due to the type of hernia and individual differences. After the patient's abdominal wall is propped up by a support and protection device (such as a balloon separator), the position of the support and protection device and the hernia will also be different due to differences in the individual's intra-abdominal conditions. Sometimes the device can be adjusted to be relatively far away from the hernia while playing a supporting and protective role, so as to provide sufficient space for laparoscopic observation and subsequent doctor's surgical operations, and ensure the normal progress of these surgical procedures. However, sometimes there are some situations where the device cannot be adjusted to a position relatively far away from the hernia. At this time, after the device props up the abdominal wall, it is easy to interfere with subsequent surgical operations.

[0054] When the device cannot be adjusted to a position relatively far from the position of the hernia, first disinfect the several surgical incisions (observation incisions and operation incisions, etc.) pre-positioned on the patient's skin, and then slowly extend the second pipe 8, the rotating pipe 9 and the first pipe 5 from the observation incision into the patient's preperitoneal space in turn to avoid contact between these pipes and the abdominal wall and peritoneum, thereby reducing damage to the patient's abdominal wall and peritoneum in this process. After extending into the appropriate position, the doctor controls the three-way valve 3 (i.e., selects the connection sequence between the inflation bag 4 and the first air bag 6 and the second air bag 7) to inflate the first air bag 6 and the second air bag 7 in turn. In this process, extend the laparoscope from the monitoring on the top of the holding shell 1 into the second pipe 8 to observe the abdominal support and whether an effective space is formed to facilitate laparoscopic observation and surgical operation. At the same time, when the first air bag 6 is inflated, the hollow part of the first air bag 6 is aligned with the surgical operation incision as much as possible through laparoscope observation. After the second airbag 7 is inflated, observe through laparoscope whether the hollow part of the second airbag 7 is aligned with the hollow part of the first airbag 6. When the two are not aligned, press the drive button 13 on the surface of the holding shell 1 to control the rotation of the drive motor 10, and the drive motor 10 drives the main gear 11 to rotate, and the main gear 11 drives the rotating pipe 9 meshing with it. Since the second airbag 7 is fixed on the surface of the rotating pipe 9, the angle of the hollow part of the second airbag 7 can be adjusted to align it with the hollow part of the first airbag 6. After completing the above operations, the doctor inserts the surgical operating tools into the patient's preperitoneal space through the operating incision, observes the condition of the preperitoneal space and inguinal hernia through laparoscope, determines the location of the hernia, and then sequentially passes the surgical tools through the hollow parts of the first airbag 6 and the second airbag 7, gradually approaches the inguinal hernia, peels back the herniated hernia sac, and then places a patch in the preperitoneal space and fixes it, closes the loose peritoneal flap, completes the operation, then opens the deflation valve, and sequentially turns the three-way valve 3 to reposition the first airbag 6 and the second airbag 7, slowly removes the device, and then sutures the incision. Moreover, the setting of double airbags can further ensure the safety during the operation. For example, when the doctor accidentally cuts and deflates one of the airbags, the other airbag can also support the patient's abdominal wall, avoiding sudden failure of the support for the abdominal wall, thereby improving the protection of the peritoneum and the patient's internal abdominal organs. At the same time, when adjusting the angle of the second airbag 7, the setting of double airbags can avoid friction with the peritoneum during the rotation of the second airbag 7, thereby reducing the damage to the internal organs and peritoneum caused by the rotation of the second airbag 7 and improving safety.

[0055] When the device can be adjusted to be relatively far from the position of the hernia while playing a supporting and protective role, it is only necessary to inflate the first airbag 6 and the second airbag 7 to complete the support of the patient's abdominal wall.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
