Description

Technical Field

[0001] This utility model relates to the field of laparoscopic surgical auxiliary instruments, and in particular to an inflatable incision auxiliary device. Background Technology

[0002] Inflatable minimally invasive surgeries, such as laparoscopic surgery, inflatable mediastinoscopy, and endoscopic breast surgery, all require inflation during the procedure to maintain a stable pressure for easy operation. Therefore, an incision aid is needed to help create a closed space between the endoscopic system, surgical instruments, and surgical site for connection.

[0003] The existing equipment has a separate bayonet design. Since multiple instruments need to be operated, surgeons usually manually connect the incision protective sleeve and medical gloves in clinical practice. Multiple endoscopic puncture needle cannulas are then connected to the fingertips of the medical gloves before use. This method is complicated, increases the operation time, and is not airtight enough. The gloves are also thin and easily damaged, which affects the operation.

[0004] Although there are devices that integrate multiple puncture needle cannulas into a single sealing cap, the incision protector and sealing cap are both circular in design, while the incision shape is irregular. Therefore, in certain specific scenarios, air leakage may occur due to incomplete sealing, which may affect the surgical procedure. In addition, because the sealing cap is made of a relatively hard material, the position of the instrument is relatively fixed when it enters through the sealing piston, which affects the flexibility of the surgery. Utility Model Content

[0005] The purpose of this invention is to provide an inflatable incision aid to solve the problems in the prior art, which can ensure the sealing of the device, maintain stable pressure in the surgical field, and allow instruments to move flexibly.

[0006] This utility model provides an inflatable incision aid device, comprising:

[0007] The body has an internal cavity, a first surface on one side along the axial direction, and a connector on the other side of the body;

[0008] A protrusion is provided on the first surface, the protrusion has a first channel, the first channel communicates with the receiving cavity, and the side of the protrusion facing away from the first surface has a first opening.

[0009] A sealing piston is located at the first opening.

[0010] In the inflatable incision aid device described above, preferably, an air injection channel is provided on the side of the main body, the air injection channel is connected to the main body, and an air injection switch is provided on the side of the air injection channel opposite to the main body.

[0011] In the inflatable incision aid device described above, preferably, the body, the protrusion, and the connector are integrally formed.

[0012] In the inflatable incision aid device described above, preferably, a plurality of protrusions are provided, and the plurality of protrusions have different heights and / or different diameters.

[0013] In the inflatable incision aid device described above, preferably, the diameter of the end of the body facing the protrusion is larger than the diameter of the side of the body facing the connector.

[0014] In the inflatable incision aid device described above, preferably, the sealing piston includes a first support member and an airtight sheet, the first support member being disposed on the first opening, and the airtight sheet being connected to the first support member.

[0015] In the inflatable incision aid device described above, preferably, the airtight sheet is provided with a single-line incision, a cross-shaped incision, or multiple valves.

[0016] In the inflatable incision aid device described above, preferably, the connector has a second channel communicating with the receiving cavity, and the side of the connector opposite to the body has a second opening.

[0017] In the inflatable incision aid device described above, preferably, the side of the connector facing away from the main body is folded over to form a bent portion, and a second support member is provided inside the bent portion.

[0018] Compared with the prior art, this utility model uses medical-grade silicone material and manufactures the connector, body and protrusion through one-piece molding technology. The surgical instrument passes through the protrusion, body and connector in sequence via the sealed piston to reach the preset position of the lesion. The whole process relies only on the sealed piston as a one-way channel, which solves the problem of air leakage at the connection between multiple components in the traditional method. This not only reduces the risk of air leakage, but also enhances the airtightness and flexibility of the device.

[0019] This device can achieve stable pressure by inflating itself, thereby providing a better field of vision and operating space. It is suitable for a variety of inflatable surgeries and can reduce the mechanical traction on tissues by traditional retractors, thus reducing the risk of tissue damage.

[0020] The protrusions isolate the instruments into independent operating spaces, preventing them from interfering with each other and ensuring precision and safety during the procedure. Furthermore, because the device is made of elastic material, the surgical instruments have more flexible operating space within it. Attached Figure Description

[0029] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] During pneumatic surgery, it is necessary to ensure airtightness at the incision site. To facilitate operation, existing designs combine the puncture device with the incision protective sheath. However, since the incision protective sheath is usually made of soft rubber, which is relatively thin and generally shallow, while the puncture device is mostly made of rigid material, it is difficult to ensure airtightness and stability when combining the two. Therefore, in clinical practice, doctors usually connect a medical glove between the incision protective sheath and the puncture device to improve the seal. However, this method is complicated to operate, and the glove is also a weak component, making it difficult to provide stability.

[0031] Therefore, this application provides an inflatable incision aid device, including a body 10, a protrusion 20, and a sealing piston 30, wherein:

[0032] See Figure 1 and Figure 3As shown, the body 10 has an internal cavity 11, a first surface 12 on one side along the axial direction, and a connector 40 on the other side. The cavity 11 provides sufficient operating space for the instrument to enter and exit. The connector 40 is used to connect the incision. Both the body 10 and the connector 40 are made of rubber, which has good elasticity and flexibility, providing support while facilitating the pulling of the instrument.

[0033] A protrusion 20 protrudes from the first surface 12 and has a first channel 21 that communicates with the receiving cavity 11. The side of the protrusion 20 facing away from the first surface 12 has a first opening 22. The protrusion 20 protrudes from the first surface 12 of the body 10, forming a sealed whole with the body 10, increasing the device's sealing performance. The first opening 22 and the first channel 21 provide a clear entry and guide for the instrument, facilitating instrument positioning and guidance. Because the instrument enters through the first channel 21, it will not move around randomly or cause excessive tissue traction, allowing the surgeon to obtain a clearer and more stable operating field of vision, facilitating more precise surgical operations, and improving the success rate and safety of the surgery.

[0034] A sealing piston 30 is disposed at the first opening 22. The sealing piston 30 can fit tightly with the first opening 22 to form a more tightly sealed space inside the device, better maintaining the stability of the internal environment. In addition, when the instrument is inserted into the first channel 21 through the first opening 22, the sealing piston 30 can play a certain role in fixing the instrument, preventing the instrument from shifting due to accidental collision or patient movement during the operation.

[0035] See Figure 1 As shown, an injection channel 50 is provided on the side of the main body 10, and the injection channel 50 is connected to the main body 10. An injection switch 51 is provided on the side of the injection channel 50 opposite to the main body 10. The injection channel 50 and the injection switch 51 are used to inject gas into the device. In addition, in one feasible embodiment, a pressure monitoring device can also be integrated on the side of the main body 10 to integrate a sensor to monitor the inflation pressure and prevent over-expansion. This is not limited here.

[0036] See Figure 1 and Figure 3 As shown, the body 10, the protrusion 20, and the connector 40 are integrally molded structures. In this embodiment, the body 10, the protrusion 20, and the connector 40 are designed as an integral structure using integral molding technology, which effectively avoids the problem of air leakage at the connection and increases the airtightness of the device. Compared with the traditional process of manufacturing each component separately and then assembling them, the integral molding technology simplifies the production process and reduces the manufacturing and assembly steps of multiple components. It can be achieved through injection molding or blow molding.

[0037] join Figure 1 As shown in Figure 2, several protrusions 20 are provided, and the protrusions 20 have different heights and / or different diameters. In this embodiment, the protrusions 20 are cylindrical, which facilitates processing and manufacturing, and provides a smooth surface for the instrument, reducing the resistance of the instrument during contact and movement. Of course, the shape of the protrusions 20 can also be an elliptical cylinder or a square prism, etc., and is not limited here.

[0038] In one possible implementation, see [link to implementation details]. Figure 2 As shown, since multiple instruments need to be connected to the device simultaneously during operation, the multiple protrusions 20 can be designed with different heights and / or diameters to accommodate multiple instruments at the same time. In addition, the independent protrusions 20 with different heights allow the instruments to be housed in separate first channels 21, reducing mutual interference. As a preferred approach, adjacent protrusions 20 are staggered and tilted outwards to increase the range of motion.

[0039] Because the cut area is small, the size of the connector 40 should not be too large. However, when multiple protrusions 20 are provided, the area occupied by the first surface 12 where the protrusions 20 are arranged is relatively large. (See...) Figure 1 and Figure 3 As shown, the diameter of the end of the body 10 facing the protrusion 20 is larger than the diameter of the side of the body 10 facing the connector 40. In this embodiment, the larger diameter end of the body 10 provides a wider space, facilitating the arrangement of multiple protrusions 20 and meeting the needs of multiple instruments operating simultaneously through the first channel 21 of different protrusions 20 in complex surgeries. A gradual space is formed from the thinner side facing the connector 40 to the thicker side facing the protrusion 20. During surgical operations, more space for instrument movement can be provided within the limited incision area, reducing mutual interference between instruments.

[0040] See Figure 2As shown, instruments need to pass through the sealing piston 30 to operate in the environment. When multiple instruments are simultaneously housed within the body 10 via different protrusions 20, the sealing piston 30 needs to provide a certain supporting force to the first opening 22. Therefore, in this embodiment, the sealing piston 30 includes a first support member 32 and an airtight seal 31. The first support member 32 is disposed on the first opening 22, and the airtight seal 31 is connected to the first support member 32. The first support member 32 is a circular or elliptical retaining ring, integrally molded during injection molding and wrapped within the rubber sleeve layer of the first opening 22. This effectively enhances the structural strength of the first opening 22, making it less prone to deformation under stress when multiple instruments pass through simultaneously, thus ensuring the overall stability of the device. The airtight seal 31 is formed on the rubber layer at the location of the first support member 32. It cooperates with the first support member 32 to better seal the first opening 22. When instruments pass through, the airtight seal 31 can tightly adhere to the instrument surface, preventing gas leakage, maintaining the pneumoperitoneum pressure or other specific internal environment required for surgery, reducing the entry of outside air, and lowering the risk of infection.

[0041] See Figure 2 As shown, the gas-sealing sheet 31 has a single-line cut, a cross-shaped cut, or multiple valves. These cuts or valves automatically open when the instrument is inserted, providing a smooth passage and reducing insertion resistance. The multiple valve structure provides multi-layer sealing; as the instrument passes through, each layer of valves tightly adheres to the instrument surface, effectively preventing gas leakage. The above description of the structure of the gas-sealing sheet 31 is only one embodiment. In this application, the structure of the gas-sealing sheet 31 is not limited, as long as it can meet the sealing requirements and accommodate the entry and exit of instruments.

[0042] In this embodiment, see Figure 3 As shown, the connector 40 has a second channel 41 that communicates with the receiving cavity 11. The side of the connector 40 facing away from the body 10 has a second opening 42. The connector 40 is used to connect to the inside of the incision. The second opening 42 is located inside the incision, and the second channel 41 provides a clear and spacious operating channel for the instrument, facilitating surgical operations. During use, the connector 40 is first connected to the incision to form a seal. The connector 40 is slightly thinner than the body 10, and its sidewalls are concave inwards to form a certain arc, allowing for better fit to the incision and reducing pressure on surrounding tissues. The structure of the connector 40 is similar to a traditional incision protector, but the side extending outside the incision is integrally formed with the body 10, expanding the operating space of the traditional incision protector and eliminating the need for additional devices to seal the incision protector and puncture device.

[0043] See Figure 3As shown, the side of the connector 40 facing away from the body 10 is folded over to form a bent portion 43, and a second support member 44 is disposed inside the bent portion 43. In this embodiment, the second support member 44 is a circular or elliptical retaining ring encased in the rubber sealing layer of the second opening 42. The cooperation between the bent portion 43 and the second support member 44 can increase the contact area with the tissue around the incision and improve the sealing effect. In addition, by inflating the device, the chamber can expand, thereby pressing the bent portion 43 and the second support member 44 tightly around the incision to form a highly efficient seal.

[0044] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings.
