Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a protective device for abdominal incisions during laparoscopic surgery. Background Technology

[0002] A laparoscope is an instrument equipped with a miniature camera. During surgery, the incision needs to be protected, which requires the use of an incision protector. In abdominal surgery, after the surgeon makes an incision in the patient's surgical site, the incision usually closes due to tissue contraction. In the past, surgeons would use metal retractors or hooks to open the incision after making an incision in order to expose the surgical field.

[0003] Traditional laparoscopic surgery requires the use of metal retractors or hooks to open the incision, which causes significant damage to the incision and is not conducive to the patient's subsequent wound recovery. Therefore, a protective device for the incision is needed. The existing Woko disposable multi-channel single-port laparoscopic surgical trocar includes a trocar cannula, with a multi-channel platform fixedly connected to the bottom of the trocar cannula. A ventilation tube is fixedly connected to the multi-channel platform, and an air valve is fixedly connected to one side of the ventilation tube. A variable-height incision protective sleeve is detachably connected to the bottom of the multi-channel platform. The variable-height incision protective sleeve opens the incision to a certain extent and also has a certain fixation effect on the device.

[0004] In actual use, although the above-mentioned device can protect the incision surface and fix the device when the incision is opened by the cooperation of the variable height incision protective sleeve and the multi-channel platform, after the device is fixed, the incision protection device may not fit the incision surface and the device contact surface due to the abdominal bulge caused by the need to fill the abdominal cavity with gas during the operation, which may cause the device to become misaligned and fall off.

[0005] Therefore, this invention proposes a protective device for abdominal incisions during laparoscopic surgery to solve the above-mentioned problems. Utility Model Content

[0006] To address the aforementioned issues, this invention provides a laparoscopic surgery abdominal incision protection device. Through the cooperation of the balloon air tube, guide assembly, and abdominal air tube, when the abdomen bulges due to the filling of gas, the balloon air tube simultaneously supplies gas to the annular balloon, reinforcing the device and preventing it from becoming misaligned or falling off due to the abdominal bulge.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: A laparoscopic surgery abdominal incision protection device includes a puncture cannula, a multi-channel platform fixedly connected to the bottom of the puncture cannula, a balloon air guide tube and an abdominal air guide tube connected to the side wall of the multi-channel platform, the balloon air guide tube being located above the abdominal air guide tube, a sliding channel located between the balloon air guide tube and the abdominal air guide tube being provided in the side wall of the multi-channel platform, the top and bottom ends of the sliding channel being connected to the balloon air guide tube and the abdominal air guide tube respectively, a guide component for guiding airflow being slidably fitted in the sliding channel, a protective component for protecting the incision being detachably connected to the bottom of the multi-channel platform, an inflatable balloon being connected to one end of the balloon air guide tube, and a support component for providing support for the device being connected to the other end of the balloon air guide tube.

[0008] The technical principle of the above scheme is as follows: Through the design of the inflatable balloon, the balloon air tube and the support component, before the operation begins, the inflatable balloon introduces gas into the support component through the balloon air tube, causing the support component to expand to contact the incision, opening the incision and fixing the device to the incision with air pressure. Then, gas is introduced into the abdominal air tube, and at this time, part of the gas is introduced into the balloon air tube through the guide component.

[0009] The above solution has the following advantages: Compared with the existing technology, this solution inflates the support component with an airbag, which opens the incision and fixes it at the same time. When the abdominal cavity is inflated, the patient's abdomen bulges due to the gas filling. At the same time, some gas is introduced into the support component through the guide component to fix the device a second time, avoiding the device from being misaligned or falling off due to the bulging of the patient's abdomen.

[0010] Furthermore, the guide assembly includes a movable column located within the sliding channel. The bottom of the movable column is designed with an arc-shaped structure, and an L-shaped air duct is provided in the lower part of the movable column. A limiting ring is fixedly connected to the outer side of the movable column along its circumference, and the limiting ring is located inside the air duct of the airbag.

[0011] Beneficial effects: Through the design of the movable column and the arc-shaped structure, when there is no flowing gas in the airbag inlet tube but there is flowing gas in the abdominal inlet tube, the air pressure in the abdominal inlet tube is higher than that in the airbag inlet tube. The pressure difference causes the movable column to slide upward. After the movable column slides upward, the L-shaped inlet tube in the movable column connects the abdominal inlet tube and the airbag inlet tube, and some gas is introduced into the airbag inlet tube. After the airflow in the abdominal inlet tube disappears, the air pressure difference between the abdominal inlet tube and the airbag inlet tube disappears, and the movable column slides downward due to gravity. The upper limit ring of the movable column keeps the movable column in the sliding channel, so that the airbag inlet tube and the abdominal inlet tube are not connected. Thus, the connection between the airbag inlet tube and the abdominal inlet tube is controlled by the sliding of the movable column.

[0012] Furthermore, the protective component includes a double protective sleeve, with a flip ring fixedly connected to the top of the outer layer of the double protective sleeve.

[0013] Beneficial effects: The double-layer protective sleeve and flip ring design separate the incision surface from the operating space. At the same time, the device is fixed by adjusting the flip ring to the appropriate position, thereby preventing the incision surface from being contaminated, protecting the incision, and improving the success rate of surgery.

[0014] Furthermore, the support assembly includes several annular airbags, each of which is fixedly connected to the inner wall of the double-layer protective sleeve, and each annular airbag is connected to a connecting tube.

[0015] Beneficial effects: Through the design of the annular airbag and connecting tube, after the device is placed in the incision, gas is introduced into the annular airbag, so that the double-layer protective sleeve fits into the incision surface, thereby playing the role of fixing the device.

[0016] Furthermore, an inner ring is fixedly connected to the bottom wall of the double-layer protective sleeve, and a traction belt is fixedly connected to one side of the inner ring. The traction belt is located between the inner and outer layers of the double-layer protective sleeve, and one side of the traction belt extends to the outside of the double-layer protective sleeve.

[0017] Beneficial effects: Through the design of the inner sheath and traction belt, when the surgery is over and the device needs to be removed, the inner sheath can be pulled out by pulling the traction belt, thereby allowing the device to be quickly removed.

[0018] Furthermore, the inner wall of the double-layer protective sleeve is equipped with a lubricating layer.

[0019] Beneficial effects: The lubricating layer design reduces friction between the double protective sleeve and surgical instruments, thereby reducing surgical resistance.

[0020] Furthermore, the outer wall of the double-layer protective sleeve is coated with a composite coating.

[0021] Beneficial effects: The composite coating design increases the antibacterial properties of the double-layer protective sleeve and the incision surface, thereby reducing the contact between the incision surface and bacteria and protecting the incision.

[0022] Furthermore, a silicone sealing ring is provided at the connection between the inflatable airbag and the airbag duct.

[0023] Beneficial effects: The silicone sealing ring design improves the tightness of the connection between the inflatable airbag and the airbag tube, reduces air leakage, and allows for rapid inflation of the annular airbag to secure the device, thereby improving the efficiency of device fixation.

[0024] Furthermore, an air valve is provided on the side of the abdominal air tube near the inflatable bladder.

[0025] Beneficial effect: Through the design of the air valve, after the abdominal cavity is filled with gas, the air valve is closed to prevent the gas in the abdominal cavity from flowing out during the operation and thus reducing the surgical field.

[0026] Furthermore, the double-layer protective sleeve is designed with an hourglass shape.

[0027] Beneficial effects: The hourglass-shaped structure design allows the device to reduce friction during insertion by guiding the conical surface, thereby reducing damage to the incision.

[0028] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0036] The following detailed description illustrates the specific implementation method:

[0037] Example 1:

[0038] As attached Figure 1 and attached Figure 2 The following describes a laparoscopic abdominal incision protection device, comprising a puncture cannula 1. A multi-channel platform 2 is adhesively fixed to the bottom of the puncture cannula 1. To increase the surgical field of view and improve surgical accuracy, the multi-channel platform 2 has a balloon-guided air tube 3 and an abdominal air tube 4 connected to its sidewall. The balloon-guided air tube 3 and the abdominal air tube 4 have diameters of 5mm and 10mm, respectively. The balloon-guided air tube 3 is located above the abdominal air tube 4. One end of the balloon-guided air tube 3 is connected to an inflatable balloon 10, and the other end is connected to a support component for providing support to the device. This device protects the incision surface and prevents surgical instruments from directly contacting the incision. To prevent secondary trauma and infection from contact with contaminants generated during surgery, the multi-channel platform 2 has a detachable protective component at its bottom to protect the incision. Before surgery, or by introducing gas into the abdominal cavity to increase the space within the abdominal cavity and expand the surgical field, the abdomen will bulge due to the gas filling. To prevent the device from shifting or falling off due to the bulging of the abdomen, the multi-channel platform 2 has a sliding channel 6 located between the balloon air tube 3 and the abdominal air tube 4 on its side wall. The top and bottom of the sliding channel 6 are connected to the balloon air tube 3 and the abdominal air tube 4, respectively, and a guide component for guiding airflow is slidably fitted inside the sliding channel 6.

[0039] Specifically, the guide assembly includes a movable column 5 located within the sliding channel 6, with an arc-shaped bottom end. An L-shaped air guide tube 7 is provided in the lower part of the movable column 5, with a diameter of 2mm. One end of the L-shaped air guide tube 7 extends to the bottom of the movable column 5 and can communicate with the abdominal air guide tube 4. When the movable column 5 slides upward until its top is in contact with the inner top wall of the air bag air guide tube 3, the other end of the L-shaped air guide tube 7 can communicate with the air bag air guide tube 3. To prevent the movable column 5 from sliding entirely into the abdominal air guide tube 4 due to gravity, which would prevent the gas in the abdominal air guide tube 4 from flowing, a limiting ring 8 is fixedly connected to the outer side of the movable column 5 along its circumference by adhesive. The limiting ring 8 is located on the side of the movable column 5 near the top and is located inside the air bag air guide tube 3.

[0040] The protective component includes a double-layer protective sleeve 9. To facilitate the double-layer protective sleeve 9 to adapt to incisions of different heights, a flip ring 15 is fixedly connected to the top of the outer layer of the double-layer protective sleeve 9. In order for the double-layer protective sleeve 9 to fit closely to different incisions and prevent the incision from being damaged by surgical instruments during the operation, as well as to prevent surgical contamination from entering the incision and causing infection, a support component is provided inside the double-layer protective sleeve 9. The support component includes several annular airbags 11, and all annular airbags 11 are located inside the double-layer protective sleeve 9. All annular airbags 11 are fixedly connected to the inner sidewall of the double-layer protective sleeve 9 by adhesive. All annular airbags 11 are connected by a connecting tube 12. One end of the airbag air guide tube 3 passes through the sidewall of the double-layer protective sleeve 9 and connects to the annular airbag 11.

[0041] After the surgery, in order to facilitate the disassembly of the device, an inner ring 14 is fixedly connected to the bottom wall of the double protective sleeve 9 by adhesive, and a traction belt 16 is fixedly connected to one side of the inner ring 14 by adhesive. The traction belt 16 is located between the inner and outer layers of the double protective sleeve 9, and one side of the traction belt 16 extends to the outside of the double protective sleeve 9.

[0042] The specific implementation process is as follows: During laparoscopic surgery, surgical instruments are used to operate inside the abdominal cavity. Contact between the surgical instruments and the incision may aggravate the incision damage. At the same time, surgical contamination is generated during the operation. Contact between surgical contamination and the incision surface may cause incision infection, increasing the surgical risk. Therefore, an incision protection device is used to isolate the incision from surgical instruments and surgical contamination, thus protecting the incision. When the laparoscopic surgery begins, an incision is made in the patient's abdomen, and a double-layer protective sleeve 9 is placed inside the incision. In order to make the double-layer protective sleeve 9 fit the patient's incision better, an inflatable balloon 10 is used to input gas into the annular balloon 11 through the balloon air delivery tube 3, so that the annular balloon 11 inflates until the outer layer of the double-layer protective sleeve 9 fits against the incision surface. Then, the flipping ring 15 is flipped downwards to adjust the height of the double-layer protective sleeve 9 to be consistent with the height of the incision, thereby protecting the incision surface and fixing the device. After fixing, the gas delivery in the balloon air delivery tube 3 is stopped. After fixing the double-layer protective sleeve 9 to the incision, because the patient is lying flat, the abdomen is tilted downwards due to gravity, resulting in a narrow surgical field and hindering surgical operation. Therefore, gas is introduced into the abdominal cavity through the abdominal air tube 4 to increase the internal space of the abdominal cavity and thus expand the surgical field. When gas passes through the abdominal air tube 4, since there is no gas flow in the balloon air tube 3, the gas pressure in the abdominal air tube 4 is higher than that in the balloon air tube 3. At this time, the gas pressure exerts a vertical upward pressure on the moving column 5, causing the moving column 5 to... The L-shaped air tube 7 slides upwards, with one end connected to the abdominal air tube 4. When the moving column 5 slides upwards until its top wall is in contact with the inner top wall of the air tube 3, the other end of the L-shaped air tube 7 connects to the air tube 3. At this time, the abdominal air tube 4 and the air tube 3 are connected through the L-shaped air tube. The gas in the abdominal air tube 4 will flow into the air tube 3 through the L-shaped air tube. Since the diameter of the abdominal air tube 4 is 10mm, while the diameter of the L-shaped air tube 7 is 2mm, and the L-shaped air tube 7 connects to the abdominal air tube 3... The trachea 4 is perpendicular to the abdominal air tube 4 on one side. Therefore, the gas flow rate entering the L-shaped air tube 7 is less than the gas flow rate inside the abdominal air tube 7. Through the cooperation of the L-shaped air tube 7 and the moving column 5, the abdominal cavity is inflated while the annular air bag 11 is also inflated. Through the structure of the moving column 5 and the L-shaped air tube 7, the double protective sleeve 9 and the incision are further fixed during the abdominal inflation and abdominal protrusion process, thereby preventing the double protective sleeve 9 from being misaligned and falling off due to the abdominal inflation and abdominal protrusion.

[0043] After the surgery, pulling the traction belt 16 moves the inner ring 14, which is glued to the traction belt 16, out of the incision. At the same time, it moves the double protective sleeve 9 out of the incision, thus quickly and easily disassembling the device, shortening the operation time and improving the efficiency of the operation.

[0044] Example 2:

[0045] As attached Figure 1 As shown, the difference from Embodiment 1 is that, in order to avoid the device from carrying bacteria due to exposure to air before contact with the incision surface, the inner wall of the double protective sleeve 9 is provided with a composite coating, and the material of the composite coating is preferably chlorhexidine; in order to reduce the friction between the abdominal incision and the surgical instruments during the operation and reduce the resistance of the operation, the inner wall of the double protective sleeve 9 is provided with a lubricating layer, and the material of the lubricating layer is preferably polytetrachloroethylene.

[0046] The specific implementation process is as follows: Since the device is exposed to air during the process of being taken out and installed, there is a risk of carrying bacteria. The composite coating can achieve a 99% sterilization rate of the carried bacteria, thereby ensuring a sterile environment when the incision surface comes into contact with the device and reducing the risk of incision infection. At the same time, the lubricating layer reduces the friction between the surgical instruments and the double protective sleeve 9, thereby avoiding the inconvenience of the surgical instruments due to resistance, which would increase the risk of collision between the surgical instruments and the incision surface.

[0047] Example 3:

[0048] As attached Figure 1 As shown, the difference from Embodiment 2 is that, in order to increase the firmness between the inflatable airbag 10 and the airbag duct 3 and to prevent the inflatable airbag 10 from falling off due to excessive airflow during inflation, a silicone sealing ring 13 is provided at the connection between the inflatable airbag 10 and the airbag duct 3.

[0049] The specific implementation process is as follows: After the device is placed in the incision, the inflatable airbag 10 inputs gas to the annular airbag 11 through the airbag air guide tube 3 to fill the device and fix it. The design of the silicone sealing ring 13 makes the gas transmission between the inflatable airbag 10 and the airbag air guide tube 3 more stable.

[0050] Example 4:

[0051] As attached Figure 1 As shown, the difference from Embodiment 3 is that, in order to prevent gas from flowing out of the abdominal cavity and thus reducing the surgical field of view, the abdominal air duct 4 is provided with an air valve 17 on the side near the inflatable balloon 10.

[0052] The specific implementation process is as follows: Since the surgical field of view is very small when the doctor performs surgery directly through the incision, it is not convenient for surgical operation. Therefore, before the operation begins, the air valve 17 needs to be opened and gas is filled into the abdominal cavity through the abdominal air tube 4 to expand the surgical field of view in the abdominal cavity and facilitate surgical operation. After the gas is filled, the air valve 17 is closed to prevent the gas in the abdominal cavity from flowing out, which leads to a narrowing of the field of view during the operation, thus affecting the efficiency of the operation.

[0053] Example 5:

[0054] As attached Figure 1As shown, the difference from Embodiment 4 is that, in order to reduce the resistance when the double protective sleeve 9 is inserted into the cut and to reduce damage to the cut, the double protective sleeve 9 is designed as an hourglass shape.

[0055] The specific implementation process is as follows: When the device is placed into the cut, the hourglass-shaped structure reduces the friction between the device and the cut, thereby reducing the damage to the cut caused by the installation of the device.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
