Description

[0001] This application is a divisional application of the invention patent application entitled "A Smoke Exhaust System for a Single-Port Multi-Channel Puncture Device", filed on April 8, 2024, with application number 202410415133.9. Technical Field

[0002] This invention relates to the field of medical device technology, and in particular to a smoke exhaust pipe for a single-hole multi-channel puncture device smoke exhaust system. Background Technology

[0003] Laparoscopic surgery has been a significant advancement in the medical field since its introduction. Particularly in minimally invasive surgery, it has greatly improved the patient experience by reducing surgical trauma and accelerating recovery time. With continuous technological advancements, surgical instruments, including single-port multi-channel trocars, are constantly evolving to enhance surgical safety and efficiency. Laparoscopic surgery using single-port multi-channel laparoscopic protectors offers advantages such as minimal trauma, less pain, faster recovery, less scarring, and superior cosmetic results, representing the future direction of minimally invasive surgery. However, for single-port multi-channel laparoscopic protectors, an effective smoke removal system remains a key challenge in maintaining a clear surgical field and operational precision. Therefore, the demand for technologies that can more effectively remove surgical smoke continues to grow to ensure the smooth progress of surgery and patient safety.

[0004] like Figure 1 As shown, the existing single-port multi-channel laparoscopic protector, also known as a single-port multi-channel trocar or sheath, includes 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, extending beyond 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.

[0005] like Figure 2 As shown, in the design of existing single-port multi-channel trocars, the air intake and smoke exhaust positions are in the same area. However, the area where smoke is generated during surgery, such as when electrocoagulation is performed on surgical tissue 900 as shown in the figure, is spatially separated from the smoke exhaust pipe 1041. Therefore, it is difficult to solve the problem of effective airflow circulation. The gas newly entering through the air intake channel 103 is quickly sucked away by the smoke exhaust hole on the smoke exhaust pipe 1041 and does not reach the area where smoke is generated during surgery, thus failing to achieve the effect of ventilation.

[0006] like Figure 3As shown, looking at the air intake channel 103 alone, its axis is perpendicular to the platform's axis. When the gas maintaining the pneumoperitoneum enters through the air intake channel 103, it continues to move forward along the direction of the intake channel as indicated in the diagram. After flowing inside the platform, it slowly enters the cut-out protective sleeve 20 and then into the human body. Therefore, the airflow within the platform is turbulent. Once it reaches a certain saturation level before entering the human body, the efficiency of gas flow into the body is not high.

[0007] like Figure 4 Another air intake channel design is shown. The air intake channel 113 connected to the platform assembly 11 has an approximately 90-degree bend at the end, 1131, which allows the airflow to be directed downwards. However, since the opening of a human incision is often only three fingers wide, much smaller than the diameter of the platform 111, the air will not be directly projected onto the incision after entering; a certain amount of airflow reflection and sliding are required. Furthermore, if the bend at the end 1131 is directly aligned with the incision at other bending angles, it will interfere with the operation of other surgical instruments.

[0008] As can be seen from the above, the existing technological solutions all have some areas for improvement in terms of air intake and smoke exhaust to improve smoke exhaust efficiency, thereby helping to shorten the operation time and reduce the risk of surgery. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a single-port multi-channel trocar smoke extraction system. By optimizing the air intake and smoke extraction system, it reduces surgical delays caused by unclear vision due to smoke, improves smoke extraction efficiency, and effectively removes smoke from the surgical area to ensure the accuracy and safety of the surgical operation.

[0010] To achieve the above objectives, the present invention employs the following technical solutions:

[0011] A smoke exhaust pipe for a single-hole multi-channel puncture device smoke exhaust system is characterized in that the smoke exhaust pipe includes an outer smoke exhaust pipe and an inner smoke exhaust pipe, the outer smoke exhaust pipe is disposed outside a support platform, the inner smoke exhaust pipe is disposed inside the support platform, the outer smoke exhaust pipe is connected to the inner smoke exhaust pipe or the outer smoke exhaust pipe and the inner smoke exhaust pipe are integrally formed, and the inner smoke exhaust pipe can be bent into shape; the inner smoke exhaust pipe is pre-formed and bent into shape or plastically bent into shape during use.

[0012] In one optional technical solution, the inner exhaust pipe includes a second exhaust pipe and a first exhaust pipe, the outer exhaust pipe is connected to the second exhaust pipe, the second exhaust pipe is connected to the first exhaust pipe, and after bending and forming, the second exhaust pipe extends longitudinally along the inner wall of the support platform, and the first exhaust pipe extends laterally along the abdominal wall.

[0013] An optional technical solution is that the smoke exhaust inner pipe includes at least one smoke exhaust channel and a shaping channel, wherein a malleable material is disposed in the shaping channel to increase the rigidity of the smoke exhaust inner pipe.

[0014] An optional technical solution is that the smoke exhaust inner pipe includes a corrugated pipe structure, which can shrink or stretch under the action of external force.

[0015] In one optional technical solution, a protective cap is installed at the distal end of the exhaust pipe. The protective cap prevents the exhaust pipe from directly contacting the peritoneum and avoids damage to the peritoneum caused by continuous negative pressure. The protective cap is provided with multiple fine holes to prevent the ejected solid smoke from clogging the exhaust port, thereby reducing the occurrence of negative pressure.

[0016] An optional technical solution involves providing at least two pre-reserved installation holes for the smoke exhaust pipes. These holes are provided with pre-reserved thin walls. During the procedure, the doctor selects the installation location of the smoke exhaust device as needed, and then pierces the pre-reserved thin walls to complete the installation.

[0017] An optional technical solution is that the outer side of the smoke exhaust inner pipe is also provided with scale lines.

[0018] An optional technical solution is that the smoke exhaust inner tube is made of a malleable polymer material. The doctor can pre-bend and deform the shape of the smoke exhaust inner tube according to the needs to achieve the required structural state during the operation. This facilitates the air inlet at the end of the first smoke exhaust pipe in the vicinity of the surgical area. When energy instruments such as electric hooks perform electrocoagulation, cutting, or other operations in the surgical lesion area, the generated smoke is sprayed upwards and can enter the smoke exhaust hole of the first smoke exhaust pipe in a timely manner. Then, under the negative pressure suction at the third smoke exhaust pipe connector, the smoke is promptly expelled from the body, reducing the impact of smoke in the abdominal cavity on endoscopic observation during the operation.

[0019] An optional technical solution further includes a cut-out protective sleeve, which is connected to the protector platform, and the exhaust inner pipe is bent into an L-shape, U-shape, or S-shape.

[0020] An optional technical solution is that the shaped skeleton is a variable material, more specifically a deformable metal material, including copper, aluminum, or other alloy materials.

[0021] Compared with the prior art, the present invention has the following beneficial effects through the above technical solution:

[0022] The single-port multi-channel trocar fume extraction system provided by this invention, by setting a malleable or prefabricated fume extraction duct, shifts the position of the fume extraction port from directly below the single-port multi-channel trocar to directly above the surgical area, making it more suitable for inhaling the upward-spraying smoke generated by the energy instruments during surgery, thereby improving fume extraction efficiency. Simultaneously, a protective cap design is added to the end of the fume extraction duct, reducing the probability of peritoneal damage caused by continuous negative pressure and increasing safety. Through the adjusted design of the air inlet orientation, it is possible to ensure smooth airflow into the body while ensuring that the air inlet channel does not interfere with the operation of surgical instruments, thus improving air intake efficiency. With improvements in both air intake and fume extraction, the overall fume extraction effect of the single-port multi-channel laparoscopic protector is enhanced, reducing the impact of intraoperative smoke on the surgeon's surgical field of vision, improving surgical efficiency, increasing surgical safety, and providing a safer surgical procedure for patients.

Detailed Implementation

[0040] The present invention will now be described in detail with reference to the accompanying drawings.

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0042] In the accompanying drawings of this application, solid arrows represent the direction of air intake, and hollow arrows represent the direction of smoke exhaust.

[0043] like Figure 5 , Figure 6The first example shown is a smoke extraction device 134. The single-port multi-channel trocar (also called a single-port multi-channel laparoscopic sheath or single-port multi-channel laparoscopic protector) includes a protector platform 13 and an incision protector 20. The protector platform 13 includes a support platform 131, an instrument channel 132, an air inlet channel 133, and a smoke extraction device 134. The instrument channel 132, air inlet channel 133, and smoke extraction device 134 are respectively fixedly connected to the support platform 131. The smoke extraction device 134 includes a smoke extraction pipe, which includes an outer smoke extraction pipe and an inner smoke extraction pipe. The outer smoke extraction pipe is located outside the protector platform 13, and the inner smoke extraction pipe is located inside the protector platform 13. The outer smoke extraction pipe communicates with the inner smoke extraction pipe, and the inner smoke extraction pipe can be bent into shape. The inner smoke exhaust pipe includes a first smoke exhaust pipe 1341 and a second smoke exhaust pipe 1342, and the outer smoke exhaust pipe includes a third smoke exhaust pipe 1343 and a valve. The support platform 131 can be made of silicone or other flexible materials, or it can be made of rigid materials. Its main function is to provide some support for the instrument channel 132 during the operation.

[0044] like Figure 7 As shown, after the single-port multi-channel laparoscopic protector is installed on the abdominal wall, the third smoke exhaust pipe 1343 is located outside the protector platform 13 during surgery. The second smoke exhaust pipe 1342 extends into the body along the abdominal wall incision, and the first smoke exhaust pipe 1341 extends along the abdominal wall inside the abdominal wall, as close to the abdominal wall as possible. This facilitates the air inlet at the end of the first smoke exhaust pipe 1341 in the vicinity above the surgical area. When energy instruments such as electric hooks perform electrocoagulation, cutting, or other operations in the surgical lesion area, the generated smoke is sprayed upwards and can enter the smoke exhaust port of the first smoke exhaust pipe 1341 in a timely manner. Thus, under the negative pressure suction at the end of the third smoke exhaust pipe 1343, the smoke is promptly removed from the body, reducing the impact of smoke in the abdominal cavity on endoscopic observation during surgery.

[0045] like Figure 8 and Figure 9The second embodiment of the smoke extraction device 144 shown has a first smoke extraction pipe 1341 and a second smoke extraction pipe 1342 made of malleable material. The doctor can pre-bend and deform the shape of the first smoke extraction pipe 1341 and the second smoke extraction pipe 1342 according to needs, or use a pre-forming method to achieve the structural state required during surgery. The first smoke extraction pipe 1341 and / or the second smoke extraction pipe 1342 are made of malleable polymer material, including a porous tube structure with at least two channels. One channel is a hollow smoke extraction channel, and the other channel is a shaping channel that can house a shaping skeleton 1444. The shaping skeleton 1444 serves a bending and shaping function. The smoke extraction channel and the shaping channel can be arranged adjacently or nested. There can also be multiple shaping channels, which together serve a shaping function after housing the shaping skeleton 1444. The shaping skeleton 1444 is a deformable material, optionally a deformable metal material, including copper, aluminum, or other alloy materials. At the end of the first exhaust pipe 1341, a protective cap 1445 is installed. The protective cap 1445 is conical in shape and prevents the exhaust pipe from directly contacting the peritoneum, thus avoiding damage to the peritoneum caused by continuous negative pressure. The protective cap 1445 has multiple fine holes to prevent the ejected solid smoke from clogging the exhaust port, thereby reducing negative pressure. The end of the first exhaust pipe 1341 can be configured with a mesh structure to ensure that smoking does not affect the peritoneum. The outer surfaces of the first exhaust pipe 1341 and the second exhaust pipe 1342 are also provided with graduation lines, which can help doctors accurately shape the pipe according to their needs.

[0046] like Figure 10 and Figure 11 The third embodiment of the smoke exhaust device 154 shown has a first smoke exhaust pipe 1341 with a corrugated pipe structure 1544. This corrugated pipe structure 1544 can contract or extend under external force, thus achieving a variable length to accommodate different body heights. The second smoke exhaust pipe 1342 can also have a corrugated pipe structure to accommodate different depths of abdominal incisions, particularly for obese individuals. Furthermore, the first smoke exhaust pipe 1341 or the second smoke exhaust pipe 1342 can be individually or separately equipped with a sleeve structure. This sleeve structure includes a nested fixed outer tube and a movable inner tube, which can contract or extend under external force.

[0047] like Figure 12 and Figure 13 The fourth embodiment of the protector platform 2 14 shown is illustrated. Figure 13 For the present invention Figure 12The enlarged schematic diagram of the second protective platform, marked 13-13, shows that the support platform 131 has at least two pre-drilled mounting holes 1411 for the smoke exhaust device. Each pre-drilled mounting hole 1411 has a pre-reserved thin wall 1412. During the operation, the surgeon selects the installation location of the smoke exhaust device as needed, and then pierces the pre-reserved thin wall 1412 to complete the installation. For example, in gynecological uterine surgeries, the smoke exhaust pipe should be installed close to and towards the lower abdomen; in hepatobiliary surgeries, it should be installed close to and towards the upper abdomen. This pre-reserved thin wall design allows for flexible adaptation to different surgical scenarios.

[0048] like Figure 14 The fifth embodiment of the protector platform 15 shown includes an air intake channel 153 comprising an air intake valve 1531, an air intake pipe 1532, and an air intake connector 1533. The air intake connector 1533 is fixedly connected to the support platform 131. One end of the air intake connector 1533 is connected to the air intake pipe 1532, and the other end extends into the support platform 131. The opening of the air intake connector 1533 faces upward or is tilted upward. When gas enters the protector platform through the air intake connector, the airflow direction is initially upward, and then reflected by the inner wall of the support platform before flowing in the same direction into the body, forming a relatively consistent gas flow direction and improving the efficiency of air intake.

[0049] like Figure 15 The smoke extraction device 164 shown has a fourth smoke extraction pipe 1641 at the end of the first smoke extraction pipe 1341. The fourth smoke extraction pipe 1641 extends laterally from the end of the first smoke extraction pipe 1341 and extends longitudinally downwards or obliquely downwards, maintaining a safe distance from the surgical tissue 900. The fourth smoke extraction pipe 1641 has several smoke extraction holes, and the inner smoke extraction pipe composed of the first smoke extraction pipe 1341, the second smoke extraction pipe 1342, and the fourth smoke extraction pipe 1641 is bent into an S-shape. The fourth smoke extraction pipe 1641 is closer to the surgical tissue 900, which is more conducive to improving smoke extraction efficiency and also avoids the negative pressure affecting the abdominal wall.

[0050] like Figures 14-16 As shown, when gas enters the support platform through the air inlet connector 1533, the airflow direction is initially upward, and then reflected by the inner wall of the support platform before flowing in the same direction into the body, forming a relatively consistent gas flow direction and improving the efficiency of air intake. The fourth smoke exhaust pipe 1641 of the S-shaped smoke exhaust device can effectively absorb smoke near the surgical tissue 900, preventing smoke from affecting endoscopic and other operations.

[0051] Those skilled in the art should understand that the first smoke exhaust pipe 1341 and the second smoke exhaust pipe 1342 of the smoke exhaust inner tube of this application can be bent into an L-shape, a U-shape, or other complex shapes. The purpose is to bring the smoke exhaust hole of the smoke exhaust inner tube close to the surgical tissue 900 to achieve a good smoke exhaust effect without affecting the operation of other surgical instruments.

[0052] The bending and forming described in this application can be pre-formed or shaped and bent during or before surgery. After bending and forming, the device can maintain its shape roughly during surgery. Of course, after being squeezed by the incision, the bent and formed smoke exhaust device will undergo some deformation, but it will not affect the smoke exhaust effect of this application.

[0053] The exhaust pipe of this application has a certain rigidity, which can maintain a good shape; the exhaust pipe can also be a porous pipe with an internal shaping skeleton to further increase the hardness and rigidity.

[0054] This application improves smoke extraction efficiency by incorporating an air intake channel and a smoke extraction device. By simultaneously enhancing both air intake and smoke extraction, the overall smoke extraction effect of the single-port multi-channel laparoscopic protector is ensured, reducing the impact of intraoperative smoke on the surgeon's field of vision, improving surgical efficiency, increasing surgical safety, and providing a safer surgical procedure for the patient. The improved smoke extraction system reduces the risk of prolonged exposure to smoke, lowers the risk of postoperative complications, and improves the overall safety of the surgical procedure. The connectivity in this application includes direct pipe connection as well as connection via an intermediate joint fixed to a support platform. Both the air intake channel and the smoke extraction device can be integrally formed pipes or segmented pipes, and both are made of flexible materials such as silicone or rubber, or other malleable materials.
