Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an air intake channel and a single-hole multi-channel puncture device. Background Art

[0002] Laparoscopic surgery technology has been an important advancement in the medical field since its introduction. Especially in the field of minimally invasive surgery, it has greatly improved the surgical experience of patients by reducing surgical trauma and speeding up recovery time. With the continuous advancement of technology, surgical instruments, including single-port multi-channel punctures, are also evolving to improve the safety and efficiency of surgery. The use of single-port multi-channel laparoscope protectors to complete laparoscopic surgery has the advantages of less trauma, less pain, faster recovery, less scars, and outstanding cosmetic effects, which is the development direction of minimally invasive surgery. However, for single-port multi-channel laparoscope protectors, an effective smoke removal system remains a key challenge in maintaining a clear surgical field and operating precision. Therefore, the demand for technologies that can more effectively remove smoke generated by surgery continues to grow to ensure the smooth progress of the operation and the safety of patients.

[0003] like Figure 1 As shown, in the existing single-hole multi-channel puncture device, the axis of the air inlet channel 103 is perpendicular to the axis of the platform. When the gas for maintaining pneumoperitoneum enters from the air inlet channel 103, the gas will continue to move forward along the direction of the air inlet channel as indicated by the solid arrow position in the figure, and slowly enter the incision protection sleeve 20 after flowing inside the platform, and then enter the human body. It can be seen that the airflow is in a turbulent state in the platform, and when it reaches a certain saturation and then enters the human body, the efficiency of the gas flowing into the body is not high.

[0004] like Figure 2 Another existing single-hole multi-channel trocar platform assembly 11 is shown, and another air inlet channel solution, the end of the air inlet channel 113 is a curved tube end 1131 with a nearly 90-degree angle, which can direct the air flow downward, but since the human incision is often only three fingers wide after being stretched, which is much smaller than the diameter of the platform 111, the air will not be directly projected to the human incision after entering, and a certain amount of air flow reflection and sliding edge are required. However, if the curved tube end 1131 is directly aimed at the human incision at other bending angles, it will interfere with the movement of other surgical instruments when they are operated.

[0005] As can be seen from the above, the existing technical solutions all have some areas that need to be improved with respect to air intake, so as to improve smoke exhaust efficiency, thereby helping to shorten the operation time and reduce the risk of the operation. Utility Model Content

DETAILED DESCRIPTION

[0027] The utility model is described in detail below in conjunction with the accompanying drawings.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] In the drawings of this application, the solid arrows represent the air intake direction, and the hollow arrows represent the exhaust direction.

[0030] like Figure 3-Figure 5 As shown, a single-hole multi-channel puncture device (also called a single-hole multi-channel laparoscopic sheath or a single-hole multi-channel laparoscopic protector) includes a protector platform 13 and an incision protection sleeve 20, wherein the protector platform 13 includes a support platform 131, an instrument channel 132, an air inlet channel 153 and a smoke exhaust device 134, wherein the instrument channel 132, the air inlet channel 133 and the smoke exhaust device 134 are respectively connected to the support platform 131 shown. The smoke exhaust device 134 includes a smoke exhaust pipe, wherein the smoke exhaust pipe includes an outer smoke exhaust pipe and an inner smoke exhaust pipe, wherein the outer smoke exhaust pipe is arranged outside the protector platform 13, and the inner smoke exhaust pipe is arranged inside the protector platform 13, wherein the outer smoke exhaust pipe is connected to the inner smoke exhaust pipe, and the inner smoke exhaust pipe can be bent into shape. The inner smoke exhaust pipe includes a first smoke exhaust pipeline 1341 and a second smoke exhaust pipeline 1342, wherein the outer smoke exhaust pipe includes a third smoke exhaust pipeline 1343 and a valve. By providing a shaped or prefabricated smoke exhaust pipe, the position of the smoke exhaust hole is moved from the area directly below the single-hole multi-channel puncture to the area directly above the surgical area, which is more suitable for the inhalation of the upwardly ejected smoke generated by the energy device during the operation, thereby improving the smoke exhaust efficiency. The support platform 131 can be made of silicone material or other flexible materials, or can also be made of rigid materials. Its main function is to provide a certain support for the instrument channel 132 during the operation.

[0031] like Figure 3 The protector platform 13 shown, the air intake channel 153 includes 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 is deep inside the support platform 131, and the air intake connector 1533 opens upward or tilts upward. When the gas enters the protector platform through the air intake connector, the air flow direction first flows upward, and then flows into the human body in the same direction after being reflected by the inner wall of the support platform 131, forming a relatively consistent gas flow direction, thereby improving the efficiency of air intake.

[0032] like Figure 4The smoke exhaust device 134 is shown. The smoke exhaust device 134 is provided with a fourth smoke exhaust pipeline 1641 at the end of the first smoke exhaust pipeline 1341. The fourth smoke exhaust pipeline 1641 extends longitudinally downward or obliquely downward from the end of the first smoke exhaust pipeline 1341 extending transversely. The fourth smoke exhaust pipeline 1641 maintains a safe distance from the surgical tissue 900. The fourth smoke exhaust pipeline 1641 is provided with a plurality of smoke exhaust holes. The smoke exhaust inner pipe composed of the first smoke exhaust pipeline 1341, the second smoke exhaust pipeline 1342, and the fourth smoke exhaust pipeline 1641 is bent into an S shape. The fourth smoke exhaust pipeline 1641 is closer to the surgical tissue 900, which is more conducive to providing smoke exhaust efficiency and also avoids the negative pressure from affecting the abdominal wall.

[0033] like Figure 5 As shown, when the single-hole multi-channel laparoscope protector is installed on the human abdominal wall, the third smoke exhaust duct 1341 is set outside the protector platform 13 during the operation, the second smoke exhaust duct 1342 extends into the body along the abdominal wall incision, the first smoke exhaust duct 1341 extends inside the abdominal wall along the abdominal wall, as close to the abdominal wall as possible, and the fourth smoke exhaust duct 1641 is provided with a plurality of smoke exhaust holes in the vicinity of the upper range of the operating area. When energy instruments such as electric hooks are used for electrocoagulation, cutting and other operations in the surgical lesion area, the smoke generated is sprayed upward.

[0034] When the gas enters the support platform 131 through the air inlet connector 1533, the airflow first flows upward, and then is reflected by the inner wall of the support platform 131 and flows into the human body in the same direction. The smoke exhaust holes of the fourth smoke exhaust pipe 1641 absorb the smoke near the surgical tissue 900, and then the smoke is discharged from the body in time under the negative pressure suction of the third smoke exhaust pipe connector 1343, thereby reducing the impact of smoke in the abdominal cavity area on endoscopic observation during surgery.

[0035] 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 the present application can be bent into an L-shape, U-shape, S-shape, or more complex shapes. The purpose is to make the smoke exhaust holes 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.

[0036] like Figure 6 and Figure 7The displayed protector platform 2 14 has no less than two reserved installation holes 1411 for smoke exhaust pipes on the support platform 131 corresponding to the position where the smoke exhaust device is installed. The reserved installation holes 1411 for smoke exhaust pipes are provided with reserved thin walls 1412. During the operation, the doctor selects the installation position of the smoke exhaust device according to the needs, and then pierces the reserved thin wall 1412 with the joint of the smoke exhaust device to complete the installation. For example, for gynecological uterus-related surgery, the corresponding smoke exhaust pipe should be installed close to and toward the direction below the abdomen. For hepatobiliary-related surgery, the corresponding smoke exhaust pipe should be installed close to and toward the direction above the abdomen. Through such a reserved thin wall design, different surgical scenarios can be flexibly met.

[0037] The bending and forming described in the present application can be performed by pre-forming or by shaping during or before surgery. After bending and forming, the present application can roughly maintain the formed state during surgery. Of course, after being squeezed by the incision, the bent and formed smoke exhaust device will produce certain deformation, but it does not affect the smoke exhaust effect of the present application.

[0038] The smoke exhaust inner tube of the present application has a certain rigidity and can maintain a well-shaped shape; the smoke exhaust inner tube can also be a porous tube with a built-in shaping frame to further increase the rigidity.

[0039] The present application improves the smoke exhaust efficiency by providing an air intake channel and a smoke exhaust device. With the simultaneous improvement of the two dimensions of air intake and smoke exhaust, the overall smoke exhaust effect of the single-hole multi-channel laparoscope protector is guaranteed, reducing the impact of intraoperative smoke on the doctor's surgical field of view, improving surgical efficiency, increasing surgical safety, and bringing a safer surgical process to patients. The improved smoke exhaust system reduces the risk of long-term exposure to smoke, reduces the risk of postoperative complications for patients, and improves the overall safety of the surgical process. The connection of the present application includes direct connection of pipelines, and also includes connection through an intermediate joint. The air intake channel and the smoke exhaust device are made of flexible materials such as silicone, rubber or other plastic materials.
