Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a single-hole multi-channel puncture device. Background Technology

[0002] With the development of laparoscopic equipment and modern medical technology, minimally invasive laparoscopic surgery has been widely used in abdominal surgery. Compared with conventional multi-port laparoscopic surgery, single-port laparoscopic surgery, through a multi-port platform, allows for the insertion of multiple instruments through a single port, resulting in fewer incisions and better aesthetics, making it one of the development directions of minimally invasive laparoscopic surgery. A single-port multi-channel trocar includes a multi-port operating platform and an abdominal channel device connected to the multi-port operating platform. Currently, some existing single-port multi-channel trocars suffer from problems such as limited instrument operating space, easy interference between inserted instruments, unreasonable smoke extraction system design, ineffective removal of smoke generated during surgery, and difficulty in disassembly and assembly. Therefore, it is necessary to propose a single-port multi-channel trocar that is easy to disassemble, has a more complete smoke extraction system, and provides a larger instrument operating space. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a single-port multi-channel trocar, suitable for use as a channel for endoscopes and instruments in laparoscopic and other endoscopic surgeries. It is a single-port multi-channel trocar with a simple structure, convenient use, superior smoke extraction system, and large instrument operating space.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A single-port multi-channel trocar includes a multi-port operating platform and a protective sleeve. The multi-port operating platform is a large, flexible, transparent, fully soft spherical shape with several channel components on the top, solving the problem of limited space and potential collisions that can occur when doctors use other instruments.

[0006] The multi-hole operating platform includes a vent valve, a two-way stopcock, an air injection sleeve, a smoke exhaust pipe, an air pipe sleeve, a channel assembly, a sealing cap, a sealing cap fixing ring, a sealing cap fixing seat, a handle, and a sealing ring.

[0007] Furthermore, the channel assembly includes a valve channel, a channel cover, a flat gas seal cap, and a gas seal plate. The flat gas seal cap and gas seal plate are sequentially installed in the valve channel, with the flat gas seal cap fitting snugly within the valve channel. The flat gas seal cap and gas seal plate are made of silicone material, possessing good elasticity, and ensuring good sealing when other instruments are inserted. The channel cover is installed on the valve channel via a snap-fit ​​mechanism.

[0008] Furthermore, the sealing cap is designed as a transparent, fully soft spherical shape, which expands the operating space for the instruments, allowing for a clearer view of the position of the inserted instruments and resolving the problem of potential collisions between instruments. The inflated sealing cap stands more upright, effectively preventing it from tilting under its own weight.

[0009] Furthermore, the top of the sealing cover is provided with multiple channel assemblies, which are arranged at different angles around the vertical center line of the sealing cover and are connected to the interior of the sealing cover. The channel assemblies and the sealing cover are circumferentially sealed and fixed together. The top of the sealing cover is also provided with air inlet and outlet holes.

[0010] Furthermore, the gas sleeve is installed within the gas injection sleeve and the exhaust pipe. Both ends of the gas sleeve have a trapezoidal protrusion, the diameter of which is larger than the inner diameter of the gas injection sleeve and the exhaust pipe, ensuring both fixation and sealing. The gas injection sleeve and the exhaust pipe with the gas sleeve are respectively inserted into the inlet and outlet holes at the top of the sealing cap, and are circumferentially sealed and fixed to the sealing cap. A ring-shaped protrusion in the middle of the gas sleeve fixes the gas injection sleeve and the exhaust pipe within the inlet and outlet holes and provides support to prevent them from bending due to their own weight. The gas sleeve has a hollow structure, facilitating the entry of gas or the exhaust of smoke.

[0011] Furthermore, both the gas injection sleeve and the smoke exhaust pipe are equipped with a vent valve at the end furthest from the sealing cover, and a two-way stopcock is installed on the vent valve. The two-way stopcock has a vent hole. By rotating the two-way stopcock so that the vent hole and the vent valve are aligned, gas can be injected into the multi-hole operating platform through the gas injection sleeve, and the smoke generated during the operation can be discharged through the smoke exhaust pipe.

[0012] Furthermore, the exhaust pipe and gas injection sleeve are configured with two lengths, one long and one short, allowing gas to effectively enter the porous operating platform and enabling targeted smoke extraction, while effectively preventing the direct discharge of freshly introduced gas. The lower part of the exhaust pipe has multiple holes, providing a larger smoke extraction area and more effectively removing smoke generated during surgery, thus improving smoke extraction efficiency.

[0013] Furthermore, a sealing cap fixing ring is provided at the lower part of the multi-hole operating platform, and the sealing cap fixing ring is provided with two grooves.

[0014] Furthermore, the upper inner side of the sealing cap fixing seat is provided with two protrusions that match the two grooves on the sealing cap fixing ring, allowing the sealing cap fixing seat to be rotatably fixed on the sealing cap fixing ring. Handles are provided on both sides of the sealing cap fixing seat for easier gripping and use. A groove is provided at the lower end of the sealing cap fixing seat, and a sealing ring is installed in the groove to ensure the overall sealing performance of this invention.

[0015] The protective sleeve includes an insertion ring, a channel, an outer ring, a pull cord, and a pull ring.

[0016] Furthermore, one end of the pull cord is attached to the insertion ring, and the other end is attached to the pull ring. The insertion ring and outer ring are connected to the channel via heat transfer printing, and the pull cord is also fixed to the insertion ring via heat transfer printing. The channel is made of a soft film material, and the distance between the insertion ring and outer ring can be adjusted by flipping the channel. The insertion ring is made of an elastic material and easily recovers its shape after deformation. Pulling the pull ring will directly bring the insertion ring out of the cut.

[0017] Furthermore, one end of the outer ring of the protective sleeve is mounted on the sealing cap fixing seat. The inner diameter of the outer ring is slightly smaller than the upper outer diameter of the sealing cap fixing seat, so the outer ring can be fixed to the sealing cap fixing seat and is not easy to fall off.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] 1. This single-port multi-channel trocar is rationally designed, including a multi-port operating platform and a protective sleeve. The sealing cap of the multi-port operating platform is large, flexible, and transparent, making it easier to observe the insertion of instruments and reducing interference between instruments during operation. The sealing cap holder has a handle for easier handling. The inflation tube and exhaust tube are designed with two lengths, one long and one short, ensuring effective gas entry into the multi-port operating platform during inflation. The exhaust tube has multiple holes, providing a larger exhaust area and higher exhaust efficiency, ensuring the accuracy and safety of the surgical procedure.

[0020] 2. The sealing cap, channel assembly, and air injection sleeve in the multi-hole operating platform are circumferentially sealed and fixed together, and the sealing cap and sealing cap fixing ring are integrally molded. Both of these structures effectively ensure the sealing performance of the multi-hole operating platform. A sealing ring is installed between the multi-hole operating platform and the protective sleeve. Therefore, this single-hole multi-channel puncture device has good airtightness.

[0021] 3. The protective sleeve's channel is made of a flexible film, which can be flipped to adjust the length. The protective sleeve has a pull cord and pull ring on one side of the insertion ring. Under external force, the pull ring can drive the insertion ring of the protective sleeve, bringing the protective sleeve out of the cut. Attached Figure Description

[0031] See attached document Figure 1-5 The single-hole multi-channel puncture device in this embodiment includes a multi-hole operating platform 1 and a protective sleeve 2.

[0032] The multi-hole operating platform 1 includes a vent valve 1-1, a two-way stopcock 1-2, an air injection sleeve 1-3, a smoke exhaust pipe 1-4, an air pipe sleeve 1-5, a channel assembly 1-6, a sealing cap 1-7, a sealing cap fixing ring 1-8, a sealing cap fixing seat 1-9, a sealing ring 1-10, and a handle 1-11.

[0033] In the multi-hole operating platform 1, the sealing cap fixing ring 1-8 is installed on the lower side of the sealing cap 1-7, and the sealing cap 1-7 and the sealing cap fixing ring 1-8 are integrally formed. Two grooves are provided on the lower side of the sealing cap fixing ring 1-8, and two protrusions are provided on the inner side of the sealing cap fixing seat 1-9, corresponding to the grooves on the sealing cap fixing ring 1-8. By inserting the protrusions into the grooves and rotating to tighten, the sealing cap fixing seat 1-9 can be fixed to the sealing cap fixing ring 1-8. A groove is provided at the lower part of the sealing cap fixing seat 1-9 for installing the sealing ring 1-10. Handles 1-11 are provided on both sides of the sealing cap fixing seat 1-9.

[0034] The multi-hole operating platform 1 is provided with air inlet and outlet holes at the top. The air injection sleeve 1-3 and the smoke exhaust pipe 1-4 pass through the air inlet and outlet holes respectively and are connected to the sealing cover 1-7, and are fixed at the air inlet / outlet holes. The air pipe sleeve 1-5 is installed in the air injection sleeve 1-3 and the smoke exhaust pipe 1-4 and is placed at the air inlet / outlet holes to support the air injection sleeve 1-3 and the smoke exhaust pipe 1-4 to prevent the air injection sleeve 1-3 and the smoke exhaust pipe 1-4 from bending due to their own weight.

[0035] A vent valve 1-1 is installed at one end of the gas injection sleeve 1-3 and the smoke exhaust pipe 1-4. A two-way stopcock 1-2 is installed on the vent valve 1-1. The two-way stopcock 1-2 is provided with a vent hole. By rotating the two-way stopcock 1-2, the vent hole is aligned with the air inlet of the vent valve 1-1, allowing gas to be introduced into the multi-hole operating platform 1 through the gas injection sleeve 1-3, and the smoke generated during the operation is discharged through the smoke exhaust pipe 1-4.

[0036] The gas injection sleeve 1-3 and the exhaust pipe 1-4 are configured to be of different lengths, which can prevent the gas that has just been introduced from being discharged immediately, so that the gas can effectively enter the multi-hole operating platform.

[0037] The lower part of the exhaust pipes 1-4 is provided with multiple small holes to increase the exhaust area and improve the exhaust efficiency.

[0038] The channel assembly 1-6 includes a valve channel 1-6-1, a channel cover 1-6-2, a straight air-blocking cap 1-6-3, and an air-blocking plate 1-6-4;

[0039] In the channel assembly 1-6, the flat gas-blocking cap 1-6-3 is fully fitted into the valve channel 1-6-1, and the gas-blocking plate 1-6-4 is mounted on the flat gas-blocking cap 1-6-3 with its convex surface facing down. The channel cover 1-6-2 is secured to the valve channel 1-6-1 by a snap-fit. The flat gas-blocking cap 1-6-3 and the gas-blocking plate 1-6-4 are made of silicone material, ensuring good sealing even when instruments are inserted or removed.

[0040] The channel assemblies 1-6 are mounted on the sealing cover 1-7 and are distributed at different angles around the vertical center line of the sealing cover 1-7. The channel assemblies 1-6 mounted on the sealing cover 1-7 can be selected with different inner diameters to facilitate the entry of instruments of different sizes.

[0041] The protective sleeve 2 includes an outer ring 2-1, a channel 2-2, an insertion ring 2-3, a pull rope 2-4, and a pull ring 2-5.

[0042] Furthermore, one end of the pull cord 2-4 is attached to the insertion ring 2-3, and the other end is attached to the pull ring 2-5. The insertion ring 2-3, to which the pull cord 2-4 is attached, is connected to one end of the channel 2-2 via heat transfer. The other end of the channel 2-2 is also connected to the outer ring 2-1 via heat transfer. The channel 2-2 is a flexible film, and the distance between the outer ring 2-1 and the insertion ring 2-3 can be adjusted by flipping the channel 2-2.

[0043] One end of the outer ring 2-1 of the protective sleeve 2 is installed on the sealing cover fixing seat 1-8 of the multi-hole operating platform 1.

[0044] The working principle of the above embodiments is as follows:

[0045] During surgery, the insertion ring 2-3 of the protective sleeve 2 is flattened into a narrow oval shape by hand and inserted into the incision. Inside the incision, the insertion ring 2-3 recovers its round shape due to its own elasticity. Adjust the position of the pull cord 2-4 and pull ring 2-5 on the insertion ring 2-3 so that the pull cord 2-4 and pull ring 2-5 remain outside the incision. Straighten the position of the outer ring 2-1 and correct the twisting of the channel 2-2. By turning the outer ring 2-1 of the protective sleeve 2 inward with both hands, gradually shorten the length of the channel 2-2 so that the outer ring is firmly attached and fixed around the incision. At this time, the channel 2-2 is close to the incision wall, and the insertion ring 2-3 and the outer ring 2-1 are located on the inner and outer sides of the incision, respectively. Under the traction of the insertion ring 2-3 and the outer ring 2-1, the channel generates tension, causing the incision to open and expand, exposing the surgical field.

[0046] Hold the handle of the multi-port operating platform and connect the outer ring 2-1 of the protective sleeve 2 to the multi-port operating platform 1. Connect the air valve on the air insulator tube 1-3 to the pneumoperitoneum machine. After the required pneumoperitoneum pressure is reached by supplying air through the pneumoperitoneum machine, the laparoscope and instruments can be inserted for observation and surgery.

[0047] After the surgical procedure, hold the handle and remove the multi-hole operating platform 1 from the protective sleeve 2. Then pull the pull ring 2-5, which will move the insertion ring 2-3 to bring the protective sleeve 2 out of the incision.
