Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a single-hole multi-channel trocar smoke exhaust system and an incision protection sheath. Background Technique

[0002] Since the introduction of laparoscopic surgery technology, it has always been an important progress in the medical field. Especially in the field of minimally invasive surgery, it has greatly improved the surgical experience of patients by reducing surgical trauma and accelerating the recovery time. With the continuous progress of technology, surgical instruments, including single-hole multi-channel trocars, are also constantly evolving to improve the safety and efficiency of surgery. Using a single-hole multi-channel laparoscopic protector to complete laparoscopic surgery has the advantages of less trauma, less pain, faster recovery, fewer scars, and excellent cosmetic effects, which is the development direction of minimally invasive surgery. However, for a single-hole multi-channel laparoscopic protector, an effective smoke exhaust system is still a key challenge in maintaining a clear surgical field and operation accuracy. Therefore, the demand for technologies that can more effectively exhaust the smoke generated during surgery continues to grow to ensure the smooth progress of surgery and the safety of patients.

[0003] As Figure 1 shown, the existing single-hole multi-channel laparoscopic protector is also called a single-hole multi-channel trocar or sheath tube, including a platform assembly 10 and an incision protection sheath 20. The platform assembly 10 includes a platform, an instrument channel, an air inlet channel 103, and a smoke exhaust device 104. A smoke exhaust pipe 1041 is installed on the smoke exhaust device 104 and extends out of the channel platform. The incision protection sheath 20 includes a mounting ring 201, an insertion ring 203, and a protective sheath film 202 connecting the mounting ring 201 and the insertion ring 203.

[0004] As Figure 2 shown, in the design of the existing single-hole multi-channel trocar, due to the positions of air inlet and smoke exhaust being in the same area range, however, the area where smoke is generated during surgery, such as performing electrocoagulation and other operations on the surgical tissue 900 in the figure, there is a distance in space between the generated smoke and the smoke exhaust pipe 1041. Therefore, it is difficult to solve the effective circulation of air flow. The newly introduced gas in the air inlet channel 103 is quickly sucked away by the smoke exhaust holes on the smoke exhaust pipe 1041 and does not reach the area where smoke is generated during surgery, and does not achieve the effect of air exchange.

[0005] As shown in the plastic smoke exhaust pipe solution disclosed in Patent CN118000886A, the smoke exhaust and air intake can be separated in areas, and the smoke exhaust can be circulated better. However, since the smoke exhaust pipe is installed on the channel platform, when the incision protection sheath is installed on the abdominal wall and then the channel platform is installed, if the position and shape of the smoke exhaust pipe inside the abdominal wall do not reach the optimal state at this time, it is also very difficult to adjust the position.

[0006] As can be seen from the above, there are some areas for improvement in the intake and exhaust systems in the existing technical solutions, so as to improve the exhaust efficiency, help shorten the operation time, and reduce the operation risk. Summary of the Invention

[0007] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a single-hole multi-channel trocar exhaust system and an incision protector sheath. By optimizing the intake and exhaust systems, the operation delay caused by unclear vision due to smoke is reduced, the exhaust efficiency is improved, and the smoke in the operation area is effectively removed to ensure the accuracy and safety of the operation.

[0008] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0009] An incision protector sheath, wherein the incision protector sheath includes a mounting ring, an insertion ring, and a protective sheath film connecting the mounting ring and the insertion ring, and the protective sheath film is provided with a tube-passing hole.

[0010] An optional technical solution, wherein the incision protector sheath further includes an exhaust pipe, and the exhaust pipe passes through the tube-passing hole from outside to inside.

[0011] An optional technical solution, wherein the exhaust pipe is connected to the outer side and / or the inner side of the protective sheath film. The connection between the exhaust pipe and the protective sheath film includes a fixed connection and a movable connection, and the fixed connection method includes heat welding, glue bonding, or other methods that can connect and fix the two.

[0012] An optional technical solution, wherein the tube-passing hole extends inward or outward to form a channel in the incision protector sheath film, and the exhaust pipe passes through the channel.

[0013] An optional technical solution, wherein an exhaust pipe fixing member is installed on the insertion ring, and the exhaust pipe passes through and is fixed in the inner hole of the exhaust pipe fixing member. The exhaust pipe fixing member is installed and fixed on the insertion ring. After the exhaust pipe passes through the tube-passing hole and enters the protective sheath film, it then passes through the through hole of the exhaust pipe fixing member and extends outward. The exhaust pipe fixing member can restrict the position and direction of the exhaust pipe inside the abdominal wall, reduce the rigid requirement for the exhaust pipe, and even a single-hole silica gel tube can maintain the direction well, increasing the structural adaptability of the product.

[0014] An alternative technical solution, wherein the exhaust pipe is hollow inside, and reinforcing ribs and / or a shaping framework are / is further provided inside the exhaust pipe. The exhaust pipe can be a single-hole hollow pipe, a double-hole hollow pipe, or a triple-hole hollow pipe. After the hollow pipe retains the exhaust holes, a shaping framework for shaping can be installed in other inner holes, and the shaping framework can support the shaping of the exhaust pipe. When observing the cross-section of the exhaust pipe, the shape includes a circle, an ellipse, or an arc-shaped track. Reinforcing ribs are provided in the hollow exhaust passage inside the exhaust pipe to prevent the pipeline from being blocked due to excessive deformation during the shaping and bending process of the exhaust pipe.

[0015] An alternative technical solution, wherein the cross-sectional shape of the exhaust pipe includes a circle, an ellipse, an arc-shaped track, and an irregular polygon.

[0016] A single-hole multi-channel trocar smoke exhaust system, which includes the above-mentioned incision protection sleeve and further includes a platform assembly, and the platform assembly and the incision protection sleeve are detachably connected.

[0017] Another single-hole multi-channel trocar smoke exhaust system, which includes an incision protection sleeve and a platform assembly. The platform assembly and the incision protection sleeve are detachably connected. The incision protection sleeve includes a mounting ring, a placement ring, and a protective sleeve film connecting the mounting ring and the placement ring. The exhaust pipe is connected to the outside of the protective sleeve film.

[0018] The protective sleeve film of this solution does not include a pipe-passing hole. After the outer layer of the film is fixedly connected to the protective sleeve film, a channel is formed, and the exhaust pipe passes through along the channel. Compared with the first solution above, the feature of this solution is that the exhaust pipe is between the placement ring and the abdominal wall, and at the same time, the protective sleeve film has no perforation processing technology.

[0019] An alternative technical solution, wherein a channel is formed by the outer film of the incision protection sleeve, and the exhaust pipe passes through the channel.

[0020] Through the above technical solution, compared with the prior art, the present utility model has the following beneficial effects:

[0021] The single-hole multi-channel trocar smoke exhaust system provided by the present utility model installs the smoke exhaust device and the incision protection sleeve together to form a component. During the process of placing the incision protection sleeve during the operation, the smoke exhaust pipe of the smoke exhaust device can be placed inside the abdominal wall, and the position and angle of the smoke exhaust pipe inside the abdominal wall can be manually adjusted as needed, so that the smoke exhaust pipe can be as close as possible to the inside of the abdominal wall. After adjustment, the channel platform is installed. This not only ensures the smoke exhaust effect but also avoids the smoke exhaust pipe inside the abdominal wall blocking the position of other instruments or even the field of view of the endoscope mirror, thus affecting the progress of the operation. At the same time, when the smoke exhaust pipe is in a relatively good position state, it is more suitable for inhaling the upwardly ejected smoke generated by the intraoperative energy instrument, thereby improving the smoke exhaust efficiency, reducing the influence of intraoperative smoke on the doctor's surgical field of view, improving the surgical efficiency, increasing the surgical safety, and bringing a safer surgical process to the patient.

Specific embodiments

[0039] The following will be a detailed description of the present utility model with reference to the accompanying drawings.

[0040] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will further elaborate on the present utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0041] A single - hole multi - channel puncture device smoke exhaust system includes a platform component, an incision protection sleeve, and a smoke exhaust device installed on the incision protection sleeve. The platform component includes a silicone platform. The present utility model mainly designs and improves the smoke exhaust device on the incision protection sleeve. The platform component can adopt the technical solutions already disclosed in the prior art and will not be elaborated here.

[0042] Reference Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown in FIGS. 9, the incision protection sheath 21 includes a mounting ring 211, an insertion ring 213, and a protective sheath film 212 connecting the mounting ring 211 and the insertion ring 213. The protective sheath film 212 is provided with a tube-passing hole 2121. The smoke exhaust device 114 includes a smoke exhaust pipe 1141. The smoke exhaust pipe 1141 passes through the tube-passing hole 2121 from the outside to the inside relative to the protective sheath film 212 and extends into the inner side of the protective sheath film 212. An outer film layer 2122 is further included outside the tube-passing hole 2121 of the protective sheath. The outer film layer 2122 is fixedly connected to the protective sheath film 212 to form a channel, and the smoke exhaust pipe 1141 passes through the channel. The tube-passing hole 2121 can also extend inward or outward to form a channel in the incision protection sheath film for connecting the smoke exhaust pipe 1141. The connection between the smoke exhaust pipe 1141 and the protective sheath film 212 includes a fixed connection and a movable connection. The fixed connection methods include thermal welding, adhesive bonding, or other methods that can fixedly connect the two.

[0043] As Figure 7 、 8 As shown in FIGS. 9, the technical feature of this embodiment is that after being installed on the inner side of the abdominal wall, the inner side of the abdominal wall, the insertion ring 213, and the smoke exhaust pipe 1141 form a sequential relationship. The insertion ring 213 is located between the smoke exhaust pipe 1141 and the abdominal wall. The smoke exhaust device 114, the smoke exhaust pipe 1141, and the incision protection sheath film 212 are installed together to form a component. During the process of placing the incision protection sheath 21 during the operation, the smoke exhaust pipe of the smoke exhaust device 114 can be placed on the inner side of the abdominal wall, and the position and angle of the smoke exhaust pipe 1141 on the inner side of the abdominal wall can be manually adjusted as needed, so that the smoke exhaust pipe 1141 can be as close as possible to the inner side of the abdominal wall. After adjustment, the platform component 10 is installed. This not only ensures the smoke exhaust effect but also avoids the smoke exhaust pipe 1141 on the inner side of the abdominal wall blocking the positions of other instruments or even blocking the field of view of the endoscope mirror, thus affecting the progress of the operation. Therefore, the technical solution of this embodiment has obvious beneficial effects.

[0044] As Figure 10 、 Figure 11 、 Figure 12 、 Figure 13, Another optional embodiment. Compared with the above first embodiment, the solution of this embodiment further includes a smoke exhaust pipe fixing member 224, which is installed and fixed on the insertion ring 223. After the smoke exhaust pipe 1241 passes through the pipe hole and enters the protective sleeve film 222, it then passes through the through hole of the smoke exhaust pipe fixing member 224 and extends outward. The smoke exhaust pipe fixing member 224 can restrict the position and direction of the smoke exhaust pipe 1241 inside the abdominal wall, reduce the rigid requirement for the smoke exhaust pipe 1241. Even a single-hole silicone tube can well maintain its direction, increasing the structural adaptability of the product.

[0045] Such as Figure 14 , 15 , Another optional embodiment. Compared with the above first embodiment, the protective sleeve film 232 of the solution of this embodiment does not include a pipe hole. After the film outer layer 2232 is fixedly connected to the protective sleeve film 232, a channel is formed, and the smoke exhaust pipe 1341 passes through along the channel. Compared with the above first embodiment, the feature of the solution of this embodiment is that the smoke exhaust pipe 1341 is between the insertion ring 233 and the abdominal wall, and at the same time, the protective sleeve film 232 has no perforation processing technology.

[0046] Such as Figures 16 - 20 The smoke exhaust pipe 1141 shown. The smoke exhaust pipe 1141 can be a single-hole hollow pipe, a double-hole hollow pipe, or a triple-hole hollow pipe. When the hollow pipe retains the smoke exhaust hole, the hollow pipe is a 1141-1 through hole, and a shaping skeleton 1141-2 for shaping can also be installed in other inner holes. The shaping skeleton 1141-2 can support the shape of the smoke exhaust pipe; observed from the cross-section of the smoke exhaust pipe, the shape includes a circle, an ellipse, or an arc track, as Figure 17 , Reinforcing ribs 1141-3 are arranged in the internal hollow smoke exhaust channel of the smoke exhaust pipe to avoid excessive deformation of the pipeline and blockage during the shaping and bending process of the smoke exhaust pipe.

[0047] In this application, the smoke exhaust device and the incision protection sleeve are installed together to form a component. During the process of placing the incision protection sleeve during the operation, the smoke exhaust pipe of the smoke exhaust device can be placed inside the abdominal wall, and the position and angle of the smoke exhaust pipe inside the abdominal wall can be manually adjusted as needed, so that the smoke exhaust pipe can be as close as possible to the inside of the abdominal wall. After adjustment, the channel platform is installed. This not only ensures the smoke exhaust effect but also avoids the smoke exhaust pipe inside the abdominal wall blocking the positions of other instruments or even blocking the field of view of the endoscope mirror and affecting the progress of the operation; at the same time, when the smoke exhaust pipe is installed in a better position state, it is more suitable for inhaling the upward jet of smoke generated by the energy instrument during the operation, thereby improving the smoke exhaust efficiency, reducing the impact of the smoke during the operation on the doctor's operation field of view, improving the operation efficiency, increasing the operation safety, and bringing a safer operation process to the patient.
