Description

Suction system having pneumoperitoneum maintain function

The present invention relates to an inhaler having a function of maintaining diaphragm, and more specifically, to a device for maintaining diaphragm when inhaling fluid from inside the abdominal cavity and expelling it out of the body. The structure has been improved to prevent the inhalation of air for maintenance and to prevent the collapse of the oscillating state during the surgical procedure. It relates to an inhaler with a maintenance function.

Laparoscopic surgery is a surgical technique performed by making several small incisions in the abdomen and inserting a camera and various instruments into the abdominal cavity through these holes. In other words, the laparoscopic surgery is a surgery performed by inserting instruments through a trocar in a pneumoperitoneum state filled with air in the abdominal cavity. Compared to traditional open surgery, the incisions are smaller, leaving less scarring, causing less pain and a faster recovery rate. Therefore, it has the advantage of a shorter hospital stay and allowing a quicker return to daily life compared to open surgery.

This laparoscopic surgery is performed by inserting a needle into the patient's navel area after the patient is anesthetized to create a state of pneumoperitoneum (inflating the abdominal cavity by injecting carbon dioxide or air into it), and placing the necessary number of trocars in the appropriate locations in the abdomen. The surgeon can insert a camera into the abdominal cavity through the trocar to check the surgical site, and perform the surgery using instruments inserted through the trocar.

As illustrated in Fig. 1, during laparoscopic surgery, it is often necessary to suck up and discharge fluids such as washing fluid, blood, and body fluids from the body, and therefore, a suction device (1) is used. The suction device (1) according to the prior art has the advantage of sucking up and dischargeing fluids (such as washing fluid, blood, and body fluids) from the body during laparoscopic surgery, but it has the problem of sucking up and down air that maintains the abdominal cavity, making it difficult to maintain the abdominal cavity, requiring repeated re-formation of the abdominal cavity during the surgery, and extending the surgery time.

As for prior art, there is Patent Publication No. 10-2021-0154196.

The present invention has been made to solve the above problems, and the purpose of the present invention is to provide a suction device having a function of maintaining peritoneum, which can suction and discharge fluids including washing fluid, blood, and body fluids accumulated inside the abdominal cavity during laparoscopic surgery, block air for forming peritoneum from being suctioned when suctioning fluid inside the abdominal cavity, prevent the peritoneum from collapsing during surgery, and shorten the surgery time while making repeated reformation of peritoneum unnecessary during the surgery process.

The solutions to the problems of the present invention are not limited to those mentioned above, and other solutions not mentioned can be clearly understood by those skilled in the art from the description below.

In order to achieve the above object, the present invention relates to a suction device having a pneumoperitoneum maintenance function, which is disposed inside the abdominal cavity where a pneumoperitoneum is maintained during laparoscopic surgery and which sucks intraperitoneal fluid including washing fluid, blood, and body fluid from a retention space in which the fluid accumulates, the suction device comprising: a conduit body formed in a tube shape and having an inlet in the form of a through hole in one section of an end facing the retention space, and having a passage formed inside for moving the fluid introduced through the inlet to the outside of the abdominal cavity; a pocket conduit formed in a tube shape and connected to an end of the conduit body, forming a receiving space between the inlet and the fluid on the retention space side, allowing the fluid to be temporarily received in the receiving space, and having a communication port for communicating the receiving space and the retention space; And, it comprises an opening/closing buoyancy body which is arranged in the receiving space of the pocket pipe, and when a fluid flows into the receiving space through the communication port and is received, rises in the receiving space by buoyancy and gradually opens the inlet, and when the fluid flows out through the inlet to a passage, descends in the receiving space by its own weight and gradually closes the inlet.

It is preferable that the inlet formed in the above pipe body has a shape corresponding to the external shape of the opening/closing buoyancy body, and has a diameter smaller than the diameter of the opening/closing buoyancy body.

The above pocket pipe is formed with a mesh structure or a perforated pipe structure in which multiple communication ports are formed to prevent clogging of the inlet provided in the above pipe body. It is composed of a single structure and allows the fluid to pass toward the receiving space, but can block particles contained in the fluid.

In the case where the above pocket conduit is formed with the above perforated tube structure, it is preferable to further include wrinkles formed in a groove structure and having a pattern shape between the above communication ports so as to increase the contact area with the abdominal body tissue forming the above retention space.

The above pocket conduit may further include a filter member that is provided on the inside of the pocket conduit to prevent clogging of the inlet provided in the conduit body, and is arranged between the receiving space and the communication port, and filters particulate matter included in the fluid flowing into the receiving space through the communication port.

The suction device having the function of maintaining oscillation according to the present invention having the configuration described above is configured such that the end of the main body of the conduit is arranged on the side of the storage space where the fluid is stored, a pocket conduit forms a receiving space between the inlet formed in one section of the end side of the main body of the conduit and the fluid, and a buoyant opening/closing body is arranged in the receiving space and gradually opens the inlet while rising according to the level of the fluid flowing into the receiving space, and at the same time, when the fluid flows out of the receiving space into the main body of the conduit, it gradually closes the inlet (101) while descending according to the lowered level, thereby suppressing the inhalation of air other than the fluid, thereby enabling the inhalation and discharge of fluid including washing fluid, blood, body fluid, etc. accumulated in the abdominal cavity during laparoscopic surgery to the outside of the body, and when the fluid is inhaled from the abdominal cavity, the inhalation of air for forming oscillation is blocked, the collapse of the oscillation state during surgery is prevented, and the surgery time is shortened while making the repetitive re-formation of oscillation unnecessary during the surgery. It has an effect.

The following examples are detailed descriptions to help the understanding of the present invention, and it will be obvious that they do not limit the scope of the rights of the present invention. Accordingly, equivalent inventions that perform the same function as the present invention will also fall within the scope of the rights of the present invention.

In addition, in the following description, the same identification symbol means the same configuration, and unnecessary redundant descriptions and descriptions of known technologies will be omitted. In addition, descriptions of each embodiment of the present invention below that overlap with the description of the technology that serves as the background of the invention will also be omitted.

Hereinafter, an inhaler having a volatility maintenance function according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

FIG. 2 is a drawing for explaining an inhaler having a function of maintaining an up-and-down motion according to one embodiment of the present invention, FIG. 3 is a drawing illustrating a state in which an opening/closing buoyancy body rises in a receiving space of a pocket conduit employed in one embodiment of the present invention and gradually opens the inlet of the conduit body, and FIG. 4 is a drawing illustrating a state in which an opening/closing buoyancy body employed in one embodiment of the present invention gradually closes the inlet while descending due to a lowered water level of a fluid during the process of sucking the fluid.

As well illustrated in these drawings, the suction device having a pneumoperitoneum maintenance function according to one embodiment of the present invention maintains the abdominal cavity in a pneumoperitoneum state during laparoscopic surgery. It is arranged inside and is configured to suck in intraperitoneal fluid including washing fluid, blood, and body fluid to discharge the fluid outside the body, and to suck in and discharge the fluid from the storage space where the intraperitoneal fluid accumulates to the outside of the body, and comprises a conduit body (100), a pocket conduit (200), and an openable buoyancy body (300).

As illustrated in FIGS. 2 to 4, the above-described main body (100) is formed in a tube shape, has an end positioned in a storage space where intraperitoneal fluid accumulates (a space where intraperitoneal fluid is stored (dependent portion)), can be connected to a suction device positioned in a surgical space, and enables the intraperitoneal fluid to be discharged outside the body. The main body (100) of the above-described main body (100) enters the intraperitoneal cavity through a trocar positioned in the abdominal cavity of a patient for laparoscopic surgery, has an inlet (101) in the form of a through hole in one section of the end facing the storage space, and has a passage (102) provided inside to move the fluid introduced through the inlet (101) to the outside of the abdominal cavity.

The above conduit body (100) is configured so that the end side is connected to the pocket conduit (200) to form a receiving space between the fluid and the inlet (101), and allows the fluid to flow into the inlet (101) via the receiving space (201). The conduit body (100) has an inlet (101) formed in one section of the opposing surface of the end side, which is opened and closed by an opening/closing buoyancy body (300) placed in the receiving space (201).

The above pocket conduit (200) is formed in a tube shape and is connected to an end of the conduit body (100) so as to extend the conduit body (100) toward the storage space. The pocket conduit (200) is connected to the end so as to form the receiving space (201) between the inlet (101) of the conduit body (100) and the fluid on the storage space side. The pocket conduit (200) allows the intraperitoneal fluid to be temporarily received in the receiving space (201) before flowing into the inlet (101) of the conduit body (100), and allows the opening/closing buoyancy body (300) to rise and fall in the receiving space (201) and open/close the inlet (101) according to the water level of the fluid temporarily received in the receiving space.

The above pocket pipe (200) has at least one communication port (202) that allows the storage space and the receiving space (201) to communicate with each other so that the fluid on the storage space side can be introduced into the receiving space (201), so that the fluid is temporarily received in the receiving space (201) via the communication port (202) and allows the raising and lowering of the opening/closing buoyancy body (300), and can be moved to the passage (102) through the inlet (101) of the pipe body (100).

The above-mentioned opening/closing buoyancy body (300) is made of a buoyant material and is positioned in the receiving space (201) of the pocket conduit (200) so as to be able to rise/fall (raise/fall due to buoyancy), and opens/closes the inlet (101) while rising/falling according to the water level of the fluid temporarily received in the receiving space (201). As illustrated in FIG. 3, when the fluid flows into the receiving space (201) through the communication port (202) of the pocket conduit (200) and is received, the opening/closing buoyancy body (300) gradually opens the inlet (101) of the conduit body (100) while rising in the receiving space (201) according to the water level of the fluid due to buoyancy.

In addition, as illustrated in FIG. 4, the opening/closing buoyancy body (300) has the advantage of preventing air (gas for forming a undulating state) from being sucked in addition to the fluid when sucking the fluid on the side of the storage space by gradually closing the inlet (101) while lowering in the receiving space (201) according to the gradually decreasing fluid level in the receiving space (201) when the fluid temporarily received in the receiving space (201) passes through the inlet (101) and flows out to the passage (102), thereby preventing the undulating state from being released due to the discharge of air following the sucking of the fluid.

Here, the inlet (101) of the conduit body (100) is preferably formed in the form of a through-hole in the lower direction of the opposing surface formed on the end side of the conduit body when the opposing surface is divided into two equal parts in the upper and lower directions. In addition, the inlet (101) can be formed in various shapes such as a semicircle, an oval, and a square.

The above-mentioned opening/closing buoyancy body (300) gradually opens the inlet (101) while rising upward on the opposite surface in the receiving space (201) when the fluid level rises, and gradually closes the inlet (101) while descending downward on the opposite surface in the receiving space when the fluid level falls due to the suction of the fluid, thereby allowing the intra-abdominal fluid, excluding air, to be suctioned.

A suction device having a function of maintaining undulation according to an embodiment of the present invention having such a configuration is configured such that the end of the conduit body (100) is arranged on the side of the storage space where the fluid is stored, a pocket conduit (200) forms a receiving space (201) between the inlet (101) formed in a section of the end-side facing surface of the conduit body (100) and the fluid, and a buoyant opening/closing body (300) is arranged in the receiving space (201) and gradually opens the inlet (101) while rising according to the level of the fluid flowing into the receiving space, and on the other hand, when the fluid flows out of the conduit body (100) in the receiving space, it gradually closes the inlet (101) while lowering according to the lowered level, thereby suppressing the inhalation of air other than the fluid, thereby enabling the inhalation and discharge of fluid including washing fluid, blood, body fluid, etc. accumulated inside the abdominal cavity during laparoscopic surgery to the outside of the body, and preventing the inhalation of air for forming undulation when the fluid is inhaled inside the abdominal cavity. It blocks the collapse of the oscillation state during surgery, and shortens the surgical time by making the repetitive re-formation of oscillation unnecessary during the surgical process. It has an effect.

Meanwhile, the shape of the inlet (101) of the conduit body (100) corresponds to the external shape of the opening/closing buoyancy body (300), and the diameter of the inlet (101) is formed smaller than the diameter of the opening/closing buoyancy body (300), so that in the process of a fluid being sucked into a passage (102) through the inlet (101) of the conduit body (100), the opening/closing buoyancy body (300) can gradually close the inlet (101), and when the inlet (101) is closed, the opening/closing buoyancy body (300) is prevented from being sucked into the inlet (101), and a gap is prevented from being generated between the opening/closing buoyancy body (300) and the inlet (101), thereby preventing air (gas for forming a state of ups and downs) from being sucked into the inlet.

The above pocket conduit (200) may be formed of a mesh structure or a perforated pipe structure in which a plurality of communication holes (202) are formed. The pocket conduit (200) is formed of a mesh structure or a perforated pipe structure having a predetermined strength and forms a receiving space (201) that communicates with the passage (102) of the conduit body (100), thereby allowing the fluid to pass toward the receiving space (201), and blocking the movement of a particle-shaped substance contained in the fluid toward the receiving space.

In this way, the pocket conduit (200) enables the inflow of fluid into the passage (102) of the conduit body (100), but blocks the inflow of particles contained in the fluid, thereby preventing the inlet (101) provided in the conduit body (100) from being clogged when the fluid is sucked in, preventing the particles from getting stuck in the inlet (101) of the conduit body and hindering the inflow of the fluid, and preventing damage to other organs during surgery.

The above has described an inhaler having a function of maintaining the ups and downs according to one embodiment of the present invention. Hereinafter, an inhaler having a function of maintaining the ups and downs according to another embodiment of the present invention will be described.

FIG. 5 is a drawing for explaining an inhaler having a undulation maintenance function according to another embodiment of the present invention, and is a drawing for explaining a pleated part employed in another embodiment of the present invention.

This embodiment is similar to the previously described embodiment in most of its configuration, but there is a difference in the structure of the pocket conduit (200).

That is, the pocket conduit (200) employed in the present embodiment may be formed to include a plurality of folded portions (203) when formed as a perforated tube structure as illustrated in FIG. 5. The folded portions (203) are provided on the outer surface of the pocket conduit (200), and are formed concavely toward the receiving space (201) on the outer surface where the communication ports are not formed, that is, between the communication ports (202), thereby increasing the contact area with the abdominal body tissue forming the storage space, and preventing the conduit body (100) from being arbitrarily displaced within the abdominal cavity.

It is preferable that the above-mentioned wrinkled parts (203) are integrally formed on the outer surface of the pocket pipe (200), and the overall shape formed by the wrinkled parts (203) may be formed in a pattern such as a wave pattern or a grid pattern.

The above has described an inhaler having a function of maintaining the ups and downs according to another embodiment of the present invention. Hereinafter, an inhaler having a function of maintaining the ups and downs according to another embodiment of the present invention will be described.

FIG. 6 is a drawing for explaining an inhaler having a undulation maintenance function according to another embodiment of the present invention, and is a drawing for explaining a filter member employed in another embodiment of the present invention.

This embodiment is similar to the previously described embodiment in most of its configuration, but the pocket conduit (200) has a difference in structure.

That is, it is preferable that the pocket conduit (200) employed in the present embodiment further includes a filter member (210), as illustrated in FIG. 6. The filter member (210) is arranged on the inside of the pocket conduit (200), but is provided on the communication port (202) side of the pocket conduit (between the communication port and the receiving space), and may be formed in the form of a mesh. In this way, the filter member (210) is provided between the communication port (202) that communicates the receiving space (201) and the outside, and allows the fluid to pass toward the receiving space, but blocks the passage of particulate matter included in the fluid, thereby preventing the inlet (101) provided in the conduit body (100) from being clogged when the fluid is sucked in, and preventing the particulate matter from being stuck in the inlet (101) of the conduit body and hindering the sucking of the fluid.

The above filter member (210) can be detachably connected to the pocket conduit (200) and can be provided so that it can be replaced and installed in the pocket conduit (200), thereby enabling easy replacement when particles of matter are caught and preventing the passage of fluid, and has the effect of enabling smooth suction of intraperitoneal fluid.

Here, the above communication port (202) may be formed in multiple numbers on the outside of the pocket conduit (formed in multiple numbers due to the mesh structure), and in the case where the pocket conduit (200) is formed in a perforated tube structure, it may be formed in multiple numbers only on the surface facing the end-side facing surface of the conduit body (100) where the inlet (101) is formed. In addition, at least one communication port (202) may be provided only on the surface facing the end-side facing surface of the conduit body (100), that is, the surface that defines the receiving space (201).

Although various embodiments of the present invention have been described above, the embodiments and the drawings attached to the present specification only clearly illustrate a part of the technical idea included in the present invention, and it will be obvious that all modified examples and specific embodiments that can be easily inferred by a person skilled in the art within the scope of the technical idea included in the specification and drawings of the present invention are included in the scope of the rights of the present invention.
