Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a single-hole multi-channel puncture device. Background Art

[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-hole laparoscopic surgery, single-hole laparoscopic surgery uses a multi-hole platform to achieve the entry of multiple instruments through one hole. It has the characteristics of fewer incisions and more aesthetics, and is one of the development directions of minimally invasive laparoscopic surgery. A single-hole multi-channel puncture device includes a multi-hole operating platform and an abdominal channel device connected to the multi-hole operating platform. Some of the existing single-hole multi-channel puncture devices have problems such as narrow instrument operation space, easy interference between inserted instruments, unreasonable smoke exhaust system settings, inability to effectively exhaust the smoke generated during surgery, and difficulty in disassembly and assembly. Therefore, it is necessary to propose a single-hole multi-channel puncture device that is easy to disassemble, has a more complete smoke exhaust system, and has a larger instrument operation space. Summary of the invention

[0003] The purpose of the present invention is to provide a single-hole multi-channel puncture device to solve the above-mentioned shortcomings, which is suitable for use as a channel for endoscopes and instruments in laparoscopic and other endoscopic surgeries. It is a single-hole multi-channel puncture device with simple structure, convenient use, better smoke exhaust system and large instrument operation space.

[0004] To achieve the above object, the present invention provides the following technical solutions: A single-hole multi-channel puncture device includes a multi-hole operating platform and a protective cover. The multi-hole operating platform is set to be a transparent full soft ball, large and soft, with a plurality of channel components arranged on the top, which solves the problem of small space and easy conflict when doctors use other instruments.

[0005] The multi-hole operating platform comprises a ventilation valve, a two-way stopcock, a gas injection sleeve, a smoke exhaust pipe, a trachea sleeve, a channel component, a sealing cover, a sealing cover fixing ring, a sealing cover fixing seat, a handle, and a sealing ring.

[0006] Furthermore, the channel assembly includes a valve channel, a channel cover, a straight air blocking cap, and an air blocking sheet. The straight air blocking cap and the air blocking sheet are sequentially installed in the valve channel, and the straight air blocking cap fully fits in the valve channel. The straight air blocking cap and the air blocking sheet are made of silicone material, have good elasticity, and can ensure good sealing when other instruments are inserted. The channel cover is installed on the valve channel by snap buckles.

[0007] Furthermore, the sealing cover is set to be a transparent full soft ball, which expands the space for instrument operation, allows for a clearer observation of the position of the instrument, and solves the problem of easy collision between instruments. The inflated sealing cover can stand more upright, effectively preventing it from tilting under its own weight.

[0008] Furthermore, the top of the sealing cover is provided with a plurality of channel components, which are arranged at different angles around the vertical center line of the sealing cover and communicate with the inside of the sealing cover, and the channel components and the sealing cover are circumferentially sealed and fixedly connected. The top of the sealing cover is also provided with air inlet and outlet holes.

[0009] Furthermore, the trachea sleeve is installed in the gas injection sleeve and the smoke exhaust pipe, and a circle of trapezoidal protrusions is provided at both ends of the trachea sleeve. The diameter of the protrusions is larger than the inner diameter of the gas injection sleeve and the smoke exhaust pipe, which can ensure the sealing performance while fixing itself. The gas injection sleeve and the smoke exhaust pipe with the trachea sleeve are respectively inserted into the air inlet and outlet holes on the top of the sealing cover, and are circumferentially sealed and fixedly connected with the sealing cover. A circle of annular protrusions is provided in the middle of the trachea sleeve, which can fix the gas injection sleeve and the smoke exhaust pipe in the air inlet and outlet holes and play a supporting role to prevent the gas injection sleeve and the smoke exhaust pipe from bending due to their own weight. The trachea sleeve is a hollow structure, which is convenient for the entry of gas or the discharge of smoke.

[0010] Furthermore, the ends of the gas injection sleeve and the smoke exhaust pipe away from the sealing cover are both equipped with a vent valve, and a two-way cock is installed on the vent valve. The two-way cock is provided with a vent hole, and the two-way cock is rotated so that the vent hole and the vent valve are in a straight line, so that gas can be injected into the multi-hole operating platform through the gas injection sleeve, and smoke generated during the operation can be discharged through the smoke exhaust pipe.

[0011] Furthermore, the smoke exhaust pipe and the gas injection sleeve are set to two lengths, one long and one short, so that the gas can effectively enter the porous operating platform and can be exhausting smoke in a targeted manner, while effectively preventing the problem of the newly input gas being directly discharged. The lower part of the smoke exhaust pipe is provided with multiple holes, and the smoke exhaust area is larger, which can more effectively discharge the smoke generated during the operation from the body, thereby improving the efficiency of smoke exhaust.

[0012] Furthermore, a sealing cover fixing ring is provided at the lower part of the multi-hole operating platform, and two grooves are provided on the sealing cover fixing ring.

[0013] Furthermore, two protrusions are provided on the inner side of the upper end of the sealing cover fixing seat, which match the two grooves on the sealing cover fixing ring, so that the sealing cover fixing seat can be rotatably fixed on the sealing cover fixing ring. Handles are provided on both sides of the sealing cover fixing seat, which are more convenient to hold and easy to use. A circle of grooves is provided at the lower end of the sealing cover fixing seat, and the sealing ring is installed in the groove of the sealing cover fixing seat to ensure the overall sealing of the present invention.

[0014] The protective sleeve comprises an insertion ring, a channel, an outer ring, a drawstring and a draw ring.

[0015] Furthermore, one end of the pull rope is tied to the insertion ring, and the other end of the pull rope is tied to the pull ring. The insertion ring and the outer ring are connected to the channel by thermal transfer, and the pull rope is also fixed to the insertion ring by thermal transfer. The channel is made of a soft film material, and the distance between the insertion ring and the outer ring can be adjusted by flipping the channel. The insertion ring is made of an elastic material and is easy to recover after deformation. Pulling the pull ring can directly bring the insertion ring out of the incision.

[0016] Furthermore, one end of the outer ring of the protective sleeve is mounted on the sealing cover fixing seat. The inner diameter of the outer ring is slightly smaller than the outer diameter of the upper part of the sealing cover fixing seat, so the outer ring can be fixed on the sealing cover fixing seat and is not easy to fall off.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This single-hole multi-channel puncture device is reasonably designed, including a multi-hole operating platform and a protective cover. The sealing cover of the multi-hole operating platform is large, soft and transparent, making it easier to observe the operation of the inserted instrument, so that the instruments are not easily interfered with each other during operation. The sealing cover fixing seat has a handle, which is easier to use. The gas injection sleeve and the smoke exhaust pipe are set to two lengths, one long and one short, which can ensure that the gas effectively enters the multi-hole operating platform during gas injection. The smoke exhaust pipe is provided with multiple holes, the smoke exhaust area is larger, and the smoke exhaust efficiency is higher, so as to ensure the accuracy and safety of the surgical operation.

[0018] 2. The sealing cover, channel assembly, and gas injection sleeve in the multi-hole operating platform are connected by a circumferential sealing structure, and the sealing cover and the sealing cover fixing ring are an integrally formed structure. Both structures ensure the sealing of the multi-hole operating platform. A sealing ring is provided between the multi-hole operating platform and the protective cover, so a single-hole multi-channel puncture device has good air tightness.

[0019] 3. The channel of the protective cover is a flexible film, which can be turned over to adjust the length. There is a drawstring and a pull ring on one side of the protective cover insertion ring. Under the action of external force, the pull ring can drive the protective cover insertion ring and bring the protective cover out of the incision. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The multi-hole operating platform 1 includes a ventilation valve 1-1, a two-way stopcock 1-2, a gas injection sleeve 1-3, a smoke exhaust pipe 1-4, a trachea sleeve 1-5, a channel assembly 1-6, a sealing cover 1-7, a sealing cover fixing ring 1-8, a sealing cover fixing seat 1-9, a sealing ring 1-10, and a handle 1-11.

[0025] In the porous operating platform 1, the sealing cover fixing ring 1-8 is installed on the lower side of the sealing cover 1-7, and the sealing cover 1-7 and the sealing cover fixing ring 1-8 are an integrally formed structure. Two grooves are arranged on the lower side of the sealing cover fixing ring 1-8, and two protrusions are arranged on the inner side of the sealing cover fixing seat 1-9, which correspond to the grooves on the sealing cover fixing ring 1-8. The protrusions are inserted into the grooves and rotated and tightened, and the sealing cover fixing seat 1-9 can be fixed to the sealing cover fixing ring 1-8. A circle of grooves is arranged at the lower part of the sealing cover fixing seat 1-9 for installing the sealing ring 1-10. Handles 1-11 are arranged on both sides of the sealing cover fixing seat 1-9.

[0026] The top of the multi-hole operating platform 1 is provided with air inlet and outlet holes, and the air injection sleeve 1-3 and the smoke exhaust pipe 1-4 are connected to the sealing cover 1-7 through the air inlet and outlet holes respectively, 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.

[0027] A vent valve 1-1 is installed at one end of the gas injection sleeve 1-3 and the smoke exhaust pipe 1-4, and a two-way cock 1-2 is installed on the vent valve 1-1. The two-way cock 1-2 is provided with a vent hole. By rotating the two-way cock 1-2 so that the vent hole and the air inlet of the vent valve 1-1 are in a straight line, gas can be input into the multi-hole operating platform 1 through the gas injection sleeve 1-3, and smoke generated during surgery can be discharged through the smoke exhaust pipe 1-4.

[0028] The gas injection sleeve 1-3 and the smoke exhaust pipe 1-4 are arranged to be one long and one short, which can prevent the newly input gas from being discharged immediately and allow the gas to effectively enter the porous operating platform.

[0029] The lower part of the smoke exhaust pipe 1-4 is provided with a plurality of small holes to increase the smoke exhaust area and improve the smoke exhaust efficiency.

[0030] 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 sheet 1-6-4; In the channel assembly 1-6, the straight air blocking cap 1-6-3 is fully fitted in the valve channel 1-6-1, the air blocking sheet 1-6-4 is installed on the straight air blocking cap 1-6-3 with the convex surface facing downward, and the channel cover 1-6-2 is clamped on the valve channel 1-6-1 by a buckle. The straight air blocking cap 1-6-3 and the air blocking sheet 1-6-4 are made of silicone material, which can ensure good sealing when the instrument is in and out.

[0031] The channel components 1-6 are installed on the sealing cover 1-7 and are dispersed at different angles around the vertical center line of the sealing cover 1-7. The channel components 1-6 installed on the sealing cover 1-7 can be selected with different inner diameters to facilitate the entry of instruments of different sizes.

[0032] The protective cover 2 comprises an outer ring 2-1, a channel 2-2, an insertion ring 2-3, a drawstring 2-4, and a draw ring 2-5.

[0033] Furthermore, one end of the pull rope 2-4 is tied to the insertion ring 2-3, and the other end is tied to the pull ring 2-5. The insertion ring 2-3 with the pull rope 2-4 is connected to one end of the channel 2-2 through thermal transfer. The other end of the channel 2-2 is also connected to the outer ring 2-1 through thermal 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 turning over the channel 2-2.

[0034] One end of the outer ring 2 - 1 of the protective sleeve 2 is mounted on the sealing cover fixing seat 1 - 8 of the porous operating platform 1 .

[0035] The working principle of the above embodiment is: When used in 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. In the incision, the insertion ring 2-3 restores its circular shape by its own elasticity. Adjust the position of the drawstring 2-4 and the pull ring 2-5 on the insertion ring 2-3 so that the drawstring 2-4 and the pull ring 2-5 remain outside the incision. Straighten the position of the outer ring 2-1, correct the distortion of the channel 2-2, flip the outer ring 2-1 of the protective sleeve 2 inward with both hands, and 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 respectively located on the inner and outer sides of the incision. Under the traction of the insertion ring 2-3 and the outer ring 2-1, the channel generates tension to pull the incision open and expand, exposing the surgical field of view.

[0036] Hold the handle of the multi-hole operation platform and connect the outer ring 2-1 of the protective sleeve 2 to the multi-hole operation platform 1. Connect the ventilation valve on the gas injection sleeve 1-3 to the pneumoperitoneum machine, and after the required pneumoperitoneum pressure is reached through the pneumoperitoneum machine, the laparoscope and instruments can be inserted for observation and surgery.

[0037] After the operation, the multi-hole operation platform 1 is buckled off the protective cover 2 by holding the handle. Then the pull ring 2-5 is pulled to drive the insertion ring 2-3 to bring the protective cover 2 out of the incision.
