Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a multi-channel sealing valve and a puncture device. Background Technology

[0002] In single-port laparoscopic surgery, multiple robotic surgical instruments and endoscopes at the patient end typically need to be inserted into the body through a multi-channel single-port trocar. Because laparoscopic surgery requires maintaining pneumoperitoneum under pressure, the multi-channel trocar needs to possess a certain degree of one-way gas resistance and sealing. The one-way gas resistance and sealing of the trocar are usually achieved through its internal multi-channel one-way valve. Currently, there are two main types of multi-channel one-way valves: silicone cross valves and mechanical valves. Due to the softness of silicone, silicone cross valves are prone to deformation and leakage when instruments or endoscopes are not fully inserted, resulting in poor gas resistance. Mechanical valves, on the other hand, use elastic elements such as torsion springs for reset, leading to greater resistance when opening the valve channels. This often necessitates the addition of a manual opening button, resulting in a complex overall structure and higher cost for the trocar. In related technologies, multi-channel one-way cross valves either have poor gas resistance or complex structures when robotic surgical instruments are not fully inserted, making it impossible to simultaneously achieve good gas resistance and structural simplicity. Utility Model Content

[0003] One object of this application is to provide a multi-channel sealing valve and puncture device to at least solve the above-mentioned problems.

[0004] To achieve the above objectives, some embodiments of this application provide a multi-channel sealing valve, comprising: a valve seat having multiple holes; and multiple valve bodies, each correspondingly inserted into one of the holes in the valve seat and fixedly connected to the valve seat; wherein the edge of the valve seat has a positioning port for positioning during installation. In this way, by correspondingly inserting and fixing multiple valve bodies to the valve seat, independent multi-channel configuration is achieved, providing independent channels for the insertion of different instruments or endoscopes; the positioning port on the edge of the valve seat facilitates rapid positioning of the multi-channel sealing valve during installation, ensuring the accuracy of the installation position.

[0005] In some embodiments, the valve seat includes: a body, with a hole extending axially through the body; and a flange, circumferentially surrounding the body, and having a positioning port. Thus, the body provides a stable base for the hole, ensuring structural stability after the valve body is installed; the flange increases the connection area between the valve seat and other components, improving connection reliability; and the positioning port on the flange makes positioning easier without affecting the normal use of the hole on the body.

[0006] In some embodiments, the valve seat includes a first surface and a second surface opposite to each other. Multiple holes are individually disposed on the first surface of the valve seat and are not interconnected, while multiple holes are interconnected on the second surface of the valve seat. This ensures that the non-interconnected holes on the first surface guarantee that the channels corresponding to different valve bodies are independent at the inlet, avoiding mutual interference during instrument or endoscope insertion. The interconnected holes on the second surface facilitate centralized output of multiple channels at the outlet or unified connection with other components, adapting to specific application scenarios.

[0007] In some embodiments, the outer peripheral surface of the valve seat is constructed with a sealing groove, and the valve seat further includes a sealing ring, which is embedded in the sealing groove to seal the installation gap between the multi-channel sealing valve and adjacent components. In this way, the sealing ring can effectively seal the installation gap between the multi-channel sealing valve and adjacent components, preventing gas or liquid from leaking from the gap, improving the overall sealing performance of the multi-channel sealing valve, and meeting the requirements of sealing performance in scenarios such as laparoscopic surgery.

[0008] In some embodiments, the valve body is provided with a circumferentially surrounding sealing strip that extends toward the centerline of the valve body. This allows the sealing strip to make tight contact with the outer circumferential surface of the instrument or endoscope when it is inserted into the valve body, forming an effective seal, preventing gas leakage, and ensuring the valve body's sealing performance when the instrument is inserted.

[0009] In some embodiments, the valve body includes an open end and a normally closed sealing end disposed opposite to each other, and a sealing strip is located near the open end of the valve body. This allows for easy insertion of instruments or endoscopes at the open end, while the normally closed sealing end maintains a sealed state when no instruments are inserted. The sealing strip's proximity to the open end allows for immediate sealing upon insertion of the instrument or endoscope, reducing the possibility of gas leakage and improving the timeliness of the seal.

[0010] In some embodiments, the normally closed sealing end has a cross-shaped groove structure. In this way, the cross-shaped groove structure can remain closed when no instrument is inserted, achieving a normally closed seal due to its own structural characteristics; when an instrument is inserted, the cross groove is opened to allow the instrument to pass through, and it can automatically close after the instrument is pulled out, ensuring the sealing of the valve body in the non-use state and the unobstructed flow in the use state.

[0011] In some embodiments, some of the valve bodies have the same diameter. This allows valve bodies of the same diameter to be fitted with instruments or endoscopes of the same specifications, increasing the versatility and interchangeability of the multi-channel sealing valve. It also facilitates the selection of the appropriate valve body for insertion into the corresponding instrument based on actual needs, thus enhancing the flexibility of use.

[0012] Some embodiments of this application also provide a trocar, including a partition body and a multi-channel sealing valve as provided in the foregoing embodiments, wherein the multi-channel sealing valve is inserted into the partition body. Thus, by applying the multi-channel sealing valve to the trocar, the trocar possesses multi-channel functionality, capable of simultaneously accommodating multiple instruments or endoscopes to meet the needs of single-port surgery. Simultaneously, the sealing performance of the sealing valve ensures the trocar's airtightness and gas resistance during use.

[0013] In some embodiments, the end of the partition body is provided with a positioning boss, which is embedded in the positioning port of the valve seat to limit the circumferential rotation of the multi-channel sealing valve relative to the partition body. In this way, the cooperation between the positioning boss and the positioning port can effectively prevent the multi-channel sealing valve from rotating circumferentially relative to the partition body, ensuring the positional stability of the multi-channel sealing valve in the trocar, avoiding problems such as sealing failure or difficulty in instrument insertion caused by rotation, and improving the overall reliability of the trocar.

[0014] Compared with related technologies, the solution provided in this application embodiment achieves independent multi-channel settings through the corresponding insertion and fixing of multiple valve bodies and valve seats, providing independent channels for the insertion of different instruments or endoscopes; when one instrument or endoscope is inserted or moved alone, it will not affect the deformation of other valve bodies, resulting in air leakage; thereby improving the air resistance and sealing performance of the entire multi-channel sealing valve; in addition, the positioning port on the edge of the valve seat facilitates the rapid positioning of the multi-channel sealing valve during installation, ensuring the accuracy of the installation position; the overall structure is simple.

[0034] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0036] Combination Figures 1 to 7 As shown in the figure, an embodiment of this disclosure provides a multi-channel sealing valve, including a valve seat 10 and a plurality of valve bodies 20.

[0037] The valve seat 10 has multiple holes 101; multiple valve bodies 20 are respectively inserted into the multiple holes 101 of the valve seat 10, and are all fixedly connected to the valve seat 10; wherein, the edge of the valve seat 10 has a positioning port 102 for positioning and installation.

[0038] The multi-channel sealing valve provided in this embodiment achieves independent multi-channel configuration by inserting and fixing multiple valve bodies 20 to valve seats 10, providing independent channels for the insertion of different instruments or endoscopes; the positioning port 102 on the edge of the valve seat 10 facilitates quick positioning of the multi-channel sealing valve during installation, ensuring the accuracy of the installation position.

[0039] In this embodiment, multiple valve bodies 20 are combined with multiple holes 101 of valve seat 10 to form a multi-channel sealing valve structure, and each valve body 20 is separately separated to ensure that different valve bodies 20 do not interfere with each other when instruments or endoscopes are inserted or moved.

[0040] Optionally, the valve seat 10 is made of plastic. The valve body 20 with the instrument and the valve body 20 with the endoscope are separated from each other by a rigid plastic valve seat 10. When one instrument or endoscope is inserted or moved alone, it will not affect the deformation of the other valve bodies 20, thus preventing air leakage. This improves the air resistance and sealing performance of the entire multi-channel sealing valve.

[0041] Optionally, the valve seat 10 and the valve body 20 can be fixedly connected, for example, by adhesive bonding, to improve their strength and prevent displacement. Besides adhesive bonding, other methods for fixing the valve seat 10 and the valve body 20 can be selected and used according to the actual situation.

[0042] Optionally, the valve seat 10 is disc-shaped.

[0043] The disc-shaped structure makes the overall shape of the valve seat 10 regular and easy to process and manufacture. At the same time, the disc-shaped outer circumferential contour is conducive to the uniform arrangement of holes 101 and sealing structures (such as sealing grooves 108) in the circumferential direction, which can adapt to the needs of multi-channel layout and form a stable assembly relationship with adjacent components such as the puncture device body, thereby improving the adaptability of installation.

[0044] Optionally, the aperture portions of multiple apertures 101 are identical to accommodate instruments of different sizes.

[0045] The same aperture positions 101 can be adapted to instruments of the same size, while aperture positions 101 with different apertures can be adapted to instruments of different sizes, realizing compatibility with instruments or endoscopes of various specifications, improving the versatility of the multi-channel sealing valve, and meeting the needs of using multiple instruments simultaneously in single-port surgery.

[0046] Optionally, the axes of the multiple holes 101 are arranged in parallel to avoid interference between instruments inserted into different holes 101.

[0047] The parallel axes of the holes 101 ensure that instruments inserted into each hole 101 extend in a parallel direction, effectively avoiding interference problems such as mutual collision and entanglement of instruments during movement or operation, ensuring the smooth operation of surgical instruments and endoscopes, and improving surgical safety.

[0048] In this embodiment, the diameter, position, and number of the holes 101 are adapted to the size, number, and placement of the robotic single-port surgical instruments and endoscopes. This ensures that the design of the holes 101 closely matches the parameters of the instruments required for the actual surgery, guaranteeing that the instruments and endoscopes can be accurately and stably inserted into the holes 101. This not only ensures a good fit but also meets the layout requirements for multi-instrument collaborative operation in single-port surgery, thus improving the practicality of the device.

[0049] Optionally, the valve body 20 may be made of silicone rubber. Silicone rubber has good elasticity and sealing properties. When the instrument is inserted or removed, the valve body 20 can switch the sealing state through its own elastic deformation. At the same time, silicone rubber is soft, which can reduce wear on the instrument surface and meets the material requirements of medical devices.

[0050] Optionally, the valve body 20 is cylindrical. The cylindrical structure provides a regular channel for the insertion of instruments or endoscopes, facilitating the smooth entry and exit of instruments along the axial direction; at the same time, the circumferentially uniform structure is conducive to the setting of sealing components such as the sealing strip 201 inside the valve body 20, ensuring the uniformity and reliability of the seal.

[0051] Optionally, the valve seat 10 includes: a body 102, with a hole 101 extending through the body 102 along the axial direction; and a flange 104, which is arranged around the body 102 in the circumferential direction, and the flange 104 is configured with the positioning port 102.

[0052] The body 102 provides a stable base for setting the holes 101, ensuring the structural stability of the valve body 20 after insertion; the flange edge 104 increases the connection area between the valve seat 10 and other components, improving the reliability of the connection. At the same time, the positioning port 102 on the flange edge 104 makes the positioning function easier to achieve, and does not affect the normal use of the holes 101 on the body 102.

[0053] In this embodiment, the body 102 and the flange edge 104 are integrally formed. The flange edge 104 can be formed by bending and extending outward from the edge of the body 102.

[0054] The one-piece molding reduces the connection gap between the body 102 and the flange edge 104, improving the overall structural strength and sealing performance of the valve seat 10, avoiding the risk of loosening or leakage caused by separate connections, while simplifying the production process and improving manufacturing efficiency. In addition, the outwardly bent flange edge 104 increases the contact area between the valve seat 10 and adjacent components, improving the connection's firmness, and facilitating the installation of structures such as positioning ports 102 on the flange edge 104 without affecting the layout of the holes 101 on the body 102.

[0055] The positioning port 102 of the flange edge 104 is designed to avoid the hole 101 of the body 102 and to avoid the outer wall of the body 102 as much as possible. This avoids spatial conflict between the positioning port 102 and the hole 101 or the outer wall of the body 102, ensuring that the hole 101 can be installed normally on the valve body 20 and that the positioning port 102 can perform its positioning function normally. At the same time, it ensures the integrity of the outer wall of the body 102 and does not affect the setting of structures such as the sealing groove 108, thus improving the rationality of the valve seat 10 structural design.

[0056] Optionally, the valve seat 10 includes a first surface 105 and a second surface 106 opposite to each other, a plurality of holes 101 are individually provided on the first surface 105 of the valve seat 10 and are not interconnected with each other, and a plurality of holes 101 are interconnected on the second surface 106 of the valve seat 10.

[0057] The holes 101 on the first surface 105 are not interconnected, ensuring that the channels corresponding to different valve bodies 20 are independent at the inlet, avoiding mutual interference when instruments or endoscopes are inserted; the holes 101 on the second surface 106 are interconnected, which facilitates the centralized output of multiple channels at the outlet or the unified connection with other components, adapting to specific usage scenario requirements.

[0058] Optionally, the valve seat 10 has a spacer 107 on its second surface 106, and the spacer 107 is located at the intersection of the tangents of the plurality of holes 101. This not only improves the overall strength of the valve seat 10, but also ensures that the plurality of holes 101 are connected on the second surface 106, while ensuring that the valve body 20 and the instruments within the holes 101 do not interfere with each other.

[0059] While enhancing the overall strength of the valve seat 10, the spacer 107 can also physically separate the valve body 20 and instruments in each hole 101 when the holes 101 on the second surface 106 are connected, effectively preventing the valve body 20 or instruments from interfering with each other on the second surface 106 side and ensuring the stability of multi-channel independent operation.

[0060] Optionally, the outer peripheral surface of the valve seat 10 is constructed with a sealing groove 108, and also includes a sealing ring 30, which is embedded in the sealing groove 108 to seal the installation gap between the multi-channel sealing valve and adjacent components.

[0061] The sealing ring 30 can effectively seal the installation gap between the multi-channel sealing valve and adjacent components, preventing gas or liquid from leaking from the gap, improving the overall sealing performance of the multi-channel sealing valve, and meeting the requirements of sealing performance in scenarios such as laparoscopic surgery.

[0062] The sealing groove 108 is arranged around the circumference of the valve seat 10. The sealing ring 30 is embedded in the sealing groove 108 to achieve a radial sealing effect between the multi-channel sealing valve and adjacent components.

[0063] Optionally, the sealing ring 30 may be an O-ring 30.

[0064] Optionally, the valve body 20 is provided with a circumferentially surrounding sealing strip 201, and the sealing strip 201 extends toward the centerline of the valve body 20.

[0065] The sealing strip 201 extends towards the centerline. When an instrument or endoscope is inserted into the valve body 20, the sealing strip 201 can make close contact with the outer peripheral surface of the instrument or endoscope to form an effective seal, prevent gas leakage, and ensure the sealing performance of the valve body 20 when the instrument is inserted.

[0066] That is, when an instrument or endoscope is inserted into the valve body 20, the valve body 20 achieves a radial dynamic sealing effect after the instrument or endoscope is inserted through the sealing strip 201.

[0067] In some embodiments, the sealing strip 201 can be understood as a ring-shaped protrusion on the inner wall of the valve body 20.

[0068] Optionally, the valve body 20 includes an open end 202 and a normally closed sealing end 203 disposed opposite to each other, and the sealing strip 201 is close to the open end 202 of the valve body 20.

[0069] The open end 202 facilitates the insertion of instruments or endoscopes, while the normally closed sealing end 203 maintains a sealed state when no instruments are inserted. The sealing strip 201 is close to the open end 202 and can form a seal as soon as the instruments or endoscopes are inserted, reducing the possibility of gas leakage and improving the timeliness of the seal.

[0070] Optionally, the normally closed sealing end 203 has a cross-shaped groove structure.

[0071] When no instrument is inserted, the cross-shaped groove structure can remain closed due to its structural characteristics, achieving a normally closed seal. When an instrument is inserted, the cross groove is opened to allow the instrument to pass through, and it can automatically close again after the instrument is pulled out, ensuring the sealing of the valve body 20 in the non-use state and the unobstructed flow in the use state.

[0072] For the cross-groove structure, for example, the cross groove extends a certain depth from the end of the normally closed sealing end 203 along the axial direction of the valve body 20 into the interior of the valve body 20, forming four mutually perpendicular petal-shaped sealing pieces. When no instrument or endoscope is inserted into the valve body 20, the free ends of the four sealing pieces are tightly fitted together under their own elasticity, forming a normally closed state, which can effectively prevent gas leakage through the valve body 20 and meet the requirements of maintaining pneumoperitoneum pressure in laparoscopic surgery. When an instrument or endoscope is inserted into the valve body 20, as the insertion action proceeds, the end of the instrument or endoscope will gradually push open the four petal-shaped sealing pieces, causing the cross-groove structure to be opened, forming a channel for the instrument or endoscope to pass through; and when the instrument or endoscope is pulled out of the valve body 20, the four petal-shaped sealing pieces are tightly fitted again under their own elastic reset action, restoring the normally closed sealing state and continuing to maintain gas resistance. Furthermore, since the valve body 20 can be made of silicone rubber, which has good elasticity and flexibility, the cross-groove sealing plate is not prone to permanent deformation during opening and resetting, allowing for repeated use and ensuring the long-term reliability and sealing performance of the valve body 20. Simultaneously, combined with the cylindrical structure of the valve body 20, the center of the cross-groove structure coincides with the centerline of the cylindrical valve body 20, ensuring uniform force distribution when instruments or endoscopes are inserted, further improving sealing performance and operational smoothness.

[0073] Optionally, some of the valve bodies 20 have the same diameter.

[0074] The valve body 20 of the same diameter can be adapted to instruments or endoscopes of the same specifications, which increases the versatility and interchangeability of the multi-channel sealing valve, making it easier to select the appropriate valve body 20 to insert into the corresponding instrument according to actual needs, and improving the flexibility of use.

[0075] In addition, the valve body 20 with different diameters can be adapted to instruments or endoscopes of different sizes, increasing the versatility of the multi-channel sealing valve and making it easier to select the appropriate valve body 20 to insert the corresponding instrument according to actual needs, thus improving the flexibility of use.

[0076] This disclosure provides a puncture device, including a partition body 40 and a multi-channel sealing valve as provided in the foregoing embodiments, wherein the multi-channel sealing valve is inserted into the partition body 40.

[0077] Applying a multi-channel sealing valve to a trocar enables the trocar to have a multi-channel function, allowing it to accommodate multiple instruments or endoscopes simultaneously, meeting the needs of single-port surgery. At the same time, the sealing performance of the sealing valve ensures the trocar's airtightness and gas resistance during use.

[0078] Optionally, the end of the partition body 40 is provided with a positioning boss 401, which is embedded in the positioning port 102 of the valve seat 10 to restrict the circumferential rotation of the multi-channel sealing valve relative to the partition body 40.

[0079] The cooperation between the positioning boss 401 and the positioning port 102 can effectively prevent the multi-channel sealing valve from rotating circumferentially relative to the separating body 40, ensuring the positional stability of the multi-channel sealing valve in the trocar, avoiding problems such as sealing failure or difficulty in instrument insertion caused by rotation, and improving the overall reliability of the trocar.

[0080] Optionally, the first end of the partition body 40 is a hollow cavity structure, and multiple channels 402 are constructed along the axial direction from the first end to the second end; the multi-channel sealing valve is embedded in the hollow cavity of the first end of the partition body 40, and the valve body 20 of the multi-channel sealing valve is configured in a one-to-one correspondence with the channels 402 of the partition body 40.

[0081] The hollow cavity structure provides a stable installation space for the multi-channel sealing valve. The one-to-one correspondence between the valve body 20 and the channel 402 ensures a smooth transition of the instrument from the sealing valve to the separating body 40, realizing precise docking of the multi-channel, avoiding instrument offset or interference during transmission, and improving the overall structural coordination and operational reliability of the puncture device.

[0082] When the multi-channel sealing valve is embedded in the first end of the partition body 40, the flange edge 104 of the multi-channel sealing valve overlaps the outer edge of the first end, and the sealing ring 30 of the multi-channel sealing valve abuts against the inner wall of the partition body 40 to seal.

[0083] The positioning boss 401 is formed at the first end of the partition body 40, and the height of the positioning boss 401 is adapted to the thickness of the flange edge 104. It can limit the radial or circumferential movement of the multi-channel sealing valve, so as to avoid the positioning boss 401 being too high and thus affecting the connection between the partition body 40 and other components.
