Description

Technical Field

[0001] This invention relates to a fluid storage and fume extraction device for laparoscopic surgery, and more specifically, to a fluid storage and fume extraction device for laparoscopic surgery that can retain moisture so that gases generated during laparoscopic surgery can be easily filtered out. Background Technology

[0002] With the development of optical technology and the rapid advancement of various laparoscopic devices, many surgeries that previously relied on open abdominal surgery have been replaced by laparoscopic surgery. As a procedure that involves minimally opening the patient's stomach, inserting various surgical instruments, including surgical cameras, and simultaneously observing the abdominal cavity, laparoscopic surgery offers several advantages: fewer complications such as postoperative bleeding, infection, and adhesions; cosmetic benefits due to the small amount of tissue removed; and reduced hospital stay due to less postoperative pain and faster recovery.

[0003] Following the laparoscopic surgical procedure, after the patient is anesthetized, the surgeon inserts a needle around the patient's navel and then injects carbon dioxide into the abdominal cavity to inflate it. The surgeon then drills the necessary number of port sites at appropriate locations. A camera is inserted through the laparoscopic cannula, allowing the surgeon to view images of the interior of the abdominal cavity on a monitor positioned in front of them. While watching the monitor, the surgeon performs the necessary surgical procedures using appropriate surgical instruments.

[0004] Meanwhile, during laparoscopic surgery, the operation of equipment such as lasers, electrosurgical units, and ultrasonic cutting machines generates a large amount of harmful gases. These gases obstruct the surgeon's vision, have a foul odor, and may contain chemically and pathologically harmful particles such as carbon monoxide, carbon dioxide, bacteria, and viruses. Therefore, a gas filter is installed in the discharge channel of the laparoscopic cannula to remove these gases and ensure the safety of the surgeon. However, because the gas discharged into the gas filter contains moisture, this moisture condenses when the gas is expelled due to the temperature difference between the inside and outside of the body. When water seeps into the gas filter, the filter's performance deteriorates. Summary of the Invention

[0005] Solution to the problem

[0006] In order to solve the problems in related fields, the purpose of this invention is to provide a fluid storage and fume extraction device for laparoscopic surgery, which can retain moisture so that the gas generated during laparoscopic surgery can be filtered out.

[0007] To achieve the objectives of this invention, a fluid storage and fume extraction device for laparoscopic surgery is provided, the device being coupled to the discharge portion of a laparoscopic cannula inserted into the human body during laparoscopic surgery. The fluid storage and fume extraction device comprises: a body having a hollow space and an inlet and an outlet, the inlet being formed through a first side of the hollow space to connect with the discharge portion, and the outlet being formed through a second side of the hollow space; and a filter disposed on the first side of the body, wherein a first guide tube and a second guide tube are formed in the body, fluid flowing into the inlet flows through the first guide tube to the second side of the body, the second guide tube being formed along the outer surface of the first guide tube, and when the fluid is guided into the body by the first guide tube, moisture in the fluid is retained in the body, and gas in the fluid moves toward the filter through the space between the first and second guide tubes, is filtered by the filter, and is discharged through the outlet.

[0008] The empty space in the main body may include a first space communicating with the inlet, a second space disposed on a first side of the first space to communicate with the outlet and in which the filter is disposed, and a third space positioned between the second side of the first space and the second space. A second guide hole may be formed on the first side of the first space toward the second space, and a first guide hole may be formed on the second side of the first space toward the third space. The first guide tube may have a first side connected to the inlet and extend through the first guide hole to be positioned on the second side in the third space and have a diameter smaller than that of the first guide hole. The second guide tube may have a first side connected to the inner edge of the first guide hole and extend along the outer surface of the first guide tube to be positioned on the second side in the third space.

[0009] A first partition can be formed between the first side of the first space and the second space, a second partition can be formed between the second space and the third space, and a third partition can be formed between the third space and the first space; the second guide hole can be formed through the first partition and the first guide hole can be formed through the third partition, fluid guided from the discharge portion of the laparoscopic cannula to the third space through the inlet and the first guide tube can move through the space between the first guide tube and the second guide tube and can be guided into the first space through the first guide tube, the fluid guided into the first space can move into the second space through the second guide hole, and the gas in the fluid guided into the second space can be filtered out by the filter arranged in the second space and discharged through the outlet.

[0010] The second guide tube may include: a funnel portion connected to the inner edge of the first guide hole and protruding from the first guide hole, such that the width of the funnel portion decreases as the funnel portion moves away from the first guide hole; and an outer extension extending from the end of the funnel portion toward the end of the second guide tube.

[0011] The end of the first guide tube may protrude further than the end of the second guide tube.

[0012] The ends of the first guide tube and the second guide tube may not contact the inside of the third space.

[0013] The first guide tube and the second guide tube may be spaced apart from the bottom side facing the ground on the inner side of the third space.

[0014] The first guide tube and the second guide tube may be parallel to the bottom side.

[0015] The inlet may be positioned higher than the first guide tube, and the first guide tube may have: an inclined portion having a first side connected to the inlet and a second side inclined downward toward the first guide hole; and an inner extension extending from the second side of the inclined portion and spaced apart from the bottom side.

[0016] The diameter of the inclined portion can increase from the first side where it is positioned at the inlet to the second side where it is positioned at the first guide hole.

[0017] The fluid storage exhaust device may further include a door component for adjusting the opening area of ​​the exhaust port.

[0018] An edge portion can be formed by protruding outward from the body along the inner edge of the discharge port. The inner edge of the edge portion can have a first inner edge, a second inner edge, and a third inner edge positioned sequentially away from the second space. A blocking portion can be formed to close a first side of the first inner edge, and an opening portion can be formed to open a second side of the first edge. A pair of guide rails can be formed on both sides along the longitudinal direction of the second inner edge. The blocking portion can be positioned between the first sides of the pair of guide rails, and the opening portion can be positioned between the second sides of the pair of guide rails. A cover portion can be formed to cover the third inner edge. A slit can be formed along the longitudinal direction of the cover portion. The first side of the slit can be positioned facing the blocking portion, and the second side of the slit can be positioned facing the opening portion. The first side of the door member can have an area capable of closing the opening portion and can slide along the guide rail. The second side of the door member can protrude beyond the edge portion through the slit. When the second side of the door member slides along the slit, the first side of the door member can adjust the opening area of ​​the opening portion while moving along the guide rail.

[0019] A cover plate can be formed to cover the inner edge of the discharge port, and a through hole can be formed through a first side of the cover plate facing the blocking portion. The first side of the cover plate facing the blocking portion can be positioned further away from the second guide hole than the second side of the cover plate. The first side of the filter can be positioned to cover the second guide hole, and the second side of the filter can be positioned to face the through hole.

[0020] The inlet and the first guide hole can be positioned facing each other, and the first guide hole can have a larger diameter than the inlet.

[0021] The second space may include a first internal space communicating with the second guide hole, a second internal space communicating with the discharge port, and a third internal space positioned between the first internal space and the second internal space. A first internal partition may be formed between the first internal space and the second internal space, a second internal partition may be formed between the second internal space and the third internal space, and a third internal partition may be formed between the third internal space and the first internal space. A first internal hole may be formed through the third internal partition, and a second internal hole may be formed through the second internal partition. The filter may be arranged in the first internal space. The fluid storage and exhaust device may further include a door member for adjusting the opening area of ​​the first internal hole. Gas in the fluid moving into the first internal space through the second guide hole can be filtered out by the filter and can move into the third internal space through the first internal hole. The gas moving into the third internal space can move into the second internal space through the second internal hole, and the gas moving into the second internal space can be discharged to the discharge port.

[0022] The door component may have: a rotating shaft mounted on a first side of the third internal partition; a rotating plate formed in a plate shape to cover the first internal hole, such that the rotating shaft is inserted into the center of the rotating plate and has an opening on the first side; and a knob having a first side connected to the rotating shaft and a second side disposed outside the body, which can be rotated to move the opening to face or not face the first internal hole, thereby opening or closing the first internal hole.

[0023] The opening can be formed in an arc shape along the rotation circumference of the rotating plate, such that the width increases from the first side to the second side. When the first side of the opening is positioned to face the first internal hole, the size of the opening to the outside of the first internal hole can be greater than the size of the opening to the first internal hole when the second side of the opening is positioned to face the first internal hole.

[0024] The discharge port can be located at the upper part of the main body, and the inlet can be located below the discharge port, so that gas guided into the main body through the inlet can be manually discharged to the discharge port.

[0025] Gas emitted from the interior of the main body to the outlet can be automatically discharged by a suction device arranged at the outlet and drawing in fluid.

[0026] Beneficial effects of the invention

[0027] According to the present invention, the water generated in the third space cannot flow back to the second guide plate due to the condensation of the fluid flowing into the third space. Therefore, the performance of the filter is not degraded, and the filter can easily filter the gas flowing into the body.

[0028] Furthermore, since the end of the inner extension protrudes further than the end of the outer extension, water in the fluid dripping from the inner extension into the third space does not flow back into the outer extension.

[0029] Furthermore, since the diameter of the funnel portion increases as it moves away from the outer extension, the gas that is guided into the funnel portion through the outer extension is guided into the first space without a bottleneck.

[0030] Furthermore, since the cover plate supports one side of the filter, the filter can be formed to be larger, regardless of the size of the discharge port.

[0031] Furthermore, since the first guide tube is inclined downwards, the moisture contained in the fluid flowing inside through the inlet can easily flow downwards along the inclined portion to the inner extension. Attached Figure Description

[0044] Hereinafter, a fluid storage and fume extraction device for laparoscopic surgery according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0045] Figure 1 This is a schematic front view of a fluid storage and fume extraction device for laparoscopic surgery according to a first embodiment of the present invention, and Figure 2 This is a schematic view of the rear of a fluid storage and fume extraction device for laparoscopic surgery according to a first embodiment of the present invention.

[0046] refer to Figure 1 and Figure 2 According to a first embodiment of the present invention, a fluid storage and fume extraction device 100 for laparoscopic surgery is, for example, connected to the discharge portion (not shown) of a laparoscopic cannula inserted into the human body to filter various gases received from the discharge portion of the cannula, and includes a body 10 and a filter 180 (shown in...). Figure 3 (Middle) and door components 190.

[0047] The body 110 has an empty space and is formed in a substantially hexahedral shape. The body 110 has a top 114, a bottom 112 spaced downwardly from the top 114, and a sidewall 116 integrally connecting the top 114 and the bottom 112. An inlet 112 for connecting to a discharge portion is formed through a first side of the sidewall 116, and a connecting protrusion 121a is formed at the inlet 121 for easy connection to the discharge portion. A connecting portion 118 for securing the body 110 at a specific location in an operating room or similar space is arranged on a second side of the sidewall 116. A discharge port 123 (shown in the figure) is formed through the top 114 for discharging gas flowing in the body 110 from the discharge portion of the laparoscopic cannula. Figure 3 (Middle). An edge portion 160 is formed along the inner edge of the discharge port 123 and protrudes outward from the body 110. A cover portion 169 is formed to cover the edge portion 160, and a slit 169a is formed along the longitudinal direction of the cover portion 169. The door member 190 adjusts the opening area of ​​the discharge port 123 by sliding in the slit 169a.

[0048] Figure 3 This is a schematic view showing the interior of the main body of a fluid storage and fume extraction device for laparoscopic surgery according to a first embodiment of the present invention, and Figure 4 It is shown Figure 3 A view of section A-A'.

[0049] refer to Figures 1 to 4 The internal space of the main body 110 includes a first space 120 communicating with an inlet 121, a second space 122 communicating with an outlet 123 and in which a filter 180 is arranged, and a third space 124 positioned between the first space 120 and the second space 122. The first space 120, the second space 122, and the third space 124 are independently separated, and for this purpose, a first partition 130 is formed between the first space 120 and the second space 122, a second partition 132 is formed between the second space 122 and the third space 124, and a third partition 134 is formed between the third space 124 and the first space 120. A second guide hole 130a is formed through the first partition 130, and a first guide hole 134a is formed through the third partition 134. The inlet 121 has a first guide tube 140, and a second guide tube 150 is formed at the first guide hole 134a.

[0050] A first side of the first guide tube 140 is connected to the inner edge of the inlet 121, and a second side of the first guide tube extends through the first guide hole 134a and is positioned in the third space 124. The diameter of the first guide tube 140 is smaller than that of the first guide hole 134a. The air intake portion 121 is positioned higher than the first guide hole 134a; therefore, the first guide tube 140 has: an inclined portion 142 having a first side connected to the inlet 121 and a second side inclined downwards to the first guide hole 134a; and an inner extension 144 extending from the second side of the inclined portion 142 and spaced apart from the bottom 112. Because the first guide tube 140 is inclined downwards, moisture contained in the fluid flowing inside through the inlet easily flows through the inclined portion 142 into the inner extension 144. The diameter of the inclined portion 142 increases from its first side positioned in the inlet 121 toward its second side positioned in the first guide hole 134a. As the diameter of the inclined portion 142 gradually increases, gas and moisture can easily flow from the inclined portion 142 to the inner extension 144 without bottlenecks.

[0051] The second guide tube 150 has a first side connected to the inner edge of the first guide hole 134a and a second side extending along the outer surface of the first guide tube 140 and positioned in the third space 124. The diameter of the second guide tube 150 is larger than that of the first guide tube 140, such that the first guide tube 140 is positioned inside the second guide tube 150. The second guide tube 150 has: a funnel portion 152 connected to the inner edge of the first guide hole 134a and projecting out of the first guide hole 134a in a conical shape, the width of the funnel portion decreasing as the funnel portion moves away from the first guide hole 134a; and an outer extension 154 extending from the end of the funnel portion 152 toward the end of the second guide tube 150.

[0052] Gas guided from the discharge portion of the laparoscopic cannula to the third space 124 through the inlet 121 and the first guide tube 140 moves through the space between the first guide tube 140 and the second guide tube 150 and is guided into the first space 120 through the first guide hole 134a. The end of the inner extension 144 protrudes further than the end of the outer extension 154, thus preventing water dripping into the third space 124 through the inner extension 144 from flowing back into the outer extension 154. Since water generated in the third space 124 cannot flow back into the second guide tube 150, the performance of the filter 180 is not affected by the water in the third space 124, thus allowing the filter 180 to easily filter gas flowing in the body 110. Since the diameter of the funnel portion 152 increases as the funnel portion moves away from the outer extension 154, the gas guided to the funnel portion 152 through the outer extension 154 is easily guided into the first space 120 without a bottleneck.

[0053] The ends of the first guide tube 140 and the second guide tube 150 do not contact the inner side of the third space 124. Therefore, structurally, this has the effect that water dripping into the third space 124 cannot flow back into the end of the first guide tube 140 or the end of the second guide tube 150. Further, according to the invention, the first guide tube 140 and the second guide tube 150 can be spaced apart from the ground-facing bottom side 124a of the inner side of the third space 124. The first guide tube 140 and the second guide tube 150 can be parallel to the bottom side 124a. Therefore, this has the effect that foreign substances such as water dripping down through the first guide tube 140 to the bottom side 124a and accumulating in the third space 124 cannot flow back into the second guide tube 150.

[0054] The third space 124 has a large volume to hold a sufficient amount of water. However, since the first space 120 connects the third space 124 and the second space 122, the first space 120 can be smaller than the second space 122 and the third space 124.

[0055] Figure 5 This is a schematic view showing the state in which a door member is attached to an edge portion in a fluid storage and fume extraction device for laparoscopic surgery according to a first embodiment of the invention.

[0056] refer to Figures 1 to 5 A filter 180 is arranged in the second space 122. Gas guided into the first space 120 moves into the second space 122 through a second guide hole 130a. The gas guided into the second space 122 is filtered by the filter 180 arranged in the second space 122 and discharged through the exhaust port 123. A door member 190 is connected to the edge portion 160 to adjust the opening area of ​​the exhaust port 123.

[0057] The inner edge of the edge portion 160 has a first inner edge 160a, a second inner edge 160b, and a third inner edge 160c positioned sequentially away from the second space 122. A blocking portion 166 is formed to close a first side of the first inner edge 160a, and an opening portion 168 is formed to open a second side of the first inner edge 160a. A pair of recessed guide rails 163 are formed on both sides along the longitudinal direction of the second inner edge 160b, the blocking portion 166 being positioned between the first sides of the pair of guide rails 164, and the opening portion 168 being positioned between the second sides of the pair of guide rails 164. A cover portion 169 is formed to close the third inner edge 160c, and a slit 169a is formed along the longitudinal direction of the cover portion 169 and has a first side facing the blocking portion 166 and a second side facing the opening portion 168.

[0058] The first side of the door member 190 has an area capable of closing the opening portion 168 and can slide in the guide rail 164, while the second side of the door member 190 protrudes beyond the edge portion 160 through the slit 169a. When a user grasps and slides the second side of the door member 190 along the slit 169a, the first side of the door member 190 moves along the guide rail 164, thereby adjusting the opening area of ​​the opening portion 168. That is, when the first side of the door member 190 is positioned facing the opening portion 168, the opening portion 168 is closed, so the gas discharged through the vent 123 cannot be discharged from the second space 122. Conversely, when the first side of the door member 190 is moved to the blocking portion 166 and the opening portion 168 is opened to the slit 169a, the gas discharged through the vent 123 is discharged from the second space 122.

[0059] The size of the filter 180 arranged in the second space 122 can be limited, depending on the size of the outlet 123. That is, gas flows into the filter 180 through its longitudinal first end, and the gas flowing in the filter 180 is filtered out as it moves through the filter 180 and discharged through its second end. Therefore, the outlet 123 should be positioned close to the second end of the filter 180. However, according to the invention, the door member 190 can move over the outlet 123, and the size of the outlet 123 should be as large as the movable displacement of the door member 190. This serves as a reason for limiting the size of the filter 180.

[0060] To address the problems in this invention, a cover plate 162 is formed to cover the inner edge of the discharge port 123, and a through hole 162a is formed through a first side of the cover plate 162 facing the blocking portion 166. Further, the first side of the cover plate 162 facing the through hole 162a is positioned further away from the second guide hole 130a than the second side of the cover plate 162. A first end of the filter 180 is positioned to cover the second guide hole 130a, and a second side of the filter 180 is positioned to face the through hole 162a. Because one side of the filter 180 is supported by the cover plate 162, the filter 180 can be formed to be larger, regardless of the size of the discharge port 123.

[0061] The operation of a fluid storage and fume extraction device for laparoscopic surgery according to a first embodiment of the present invention is then described.

[0062] Figure 6 This is a schematic view illustrating the flow path of fluid flowing into a fluid storage and exhaust device for laparoscopic surgery according to a first embodiment of the invention.

[0063] refer to Figures 1 to 6 The laparoscopic cannula's discharge portion (not shown) and the connecting protrusion 121a are connected to each other via a connecting conduit (not shown). In this state, the user slides the door member 190 to the blocking portion 166 to open the opening portion 168. Therefore, fluid flowing into the inlet 121 through the connecting protrusion 121a is guided into the third space 124 via the first guide tube 140. The fluid condensed due to the temperature difference and the moisture contained in the water remain in the third space 124. Gas moving into the third space 124 moves through the space between the first guide tube 140 and the second guide tube 150 and is guided into the first space 120 through the first guide hole 134a. Gas guided into the first space 120 moves into the second space 122 through the second guide hole 130a. Gas guided into the second space 122 is filtered by the filter 180 arranged in the second space 122 and discharged to the outside sequentially through the through hole 162a and the opening portion 168.

[0064] As described above, since the water generated in the third space 124 due to the condensation of the fluid flowing in the third space 124 cannot flow back to the second guide pipe 150, the performance of the filter 180 is not degraded, and therefore the filter 180 can easily filter the gas flowing in the body 110.

[0065] Figure 7 This is a schematic view of a fluid storage and fume extraction device for laparoscopic surgery according to a second embodiment of the present invention.

[0066] refer to Figure 7According to a second embodiment of the present invention, a fluid storage and fume extraction device 200 for laparoscopic surgery includes a main body 210 and a filter 260 (shown in...). Figure 8 (Middle) and door components 280.

[0067] The main body 210 has an empty space and includes a top 214, a bottom 212 spaced downwardly from the top 214, and a sidewall 216 integrally connecting the top 214 and the bottom 212. An inlet 221 for connection to the discharge portion (not shown) of a laparoscopic cannula is formed through a first side of the sidewall 216, and a connection protrusion 221a is formed at the inlet 221. An outlet 223 for discharging gas flowing within the main body 210 to the outside is formed through a second side of the sidewall 216. A door member 280 is rotatably arranged on the top 214, and the amount of gas discharged from the main body 210 depends on the rotation angle of the door member 280.

[0068] Figure 8 This is a schematic view of a cross-section of a fluid storage and fume extraction device for laparoscopic surgery according to a second embodiment of the present invention.

[0069] refer to Figures 7 to 8 The internal space of the main body 210 includes a first space 220 communicating with an inlet 221, a second space communicating with an outlet 223 and in which a filter 260 is disposed, and a third space 224 positioned between the first space 220 and the second space 222. The first space 220, the second space 222, and the third space 224 are independently separated, and for this purpose, a first partition 230 is formed between the first space 220 and the second space 222, a second partition 232 is formed between the second space 222 and the third space 224, and a third partition 234 is formed between the third space 224 and the first space 220. A second guide hole 230a is formed through the first partition 230, and a first guide hole 234a is formed through the third partition 234. The first guide hole 232a and the inlet 221 face each other. The first guide hole 234a has a larger diameter than the inlet 221. The inlet 221 has a first guide tube 240, and a second guide tube 250 is formed at the first guide hole 234a.

[0070] A first side of the first guide tube 240 is connected to the inner edge of the inlet 221, and a second side of the first guide tube extends through the first guide hole 234a and is positioned in the third space 224. The diameter of the first guide tube 240 is smaller than that of the first guide hole 234a.

[0071] The second guide tube 250 has a first side connected to the inner edge of the first guide hole 234a and a second side extending along the outer surface of the first guide tube 240 and positioned in the third space 224. The diameter of the second guide tube 250 is larger than that of the first guide tube 240, such that the first guide tube 240 is positioned inside the second guide tube 250.

[0072] Gas guided from the discharge portion of the laparoscopic cannula to the third space 224 through the inlet 221 and the first guide tube 240 moves through the space between the first guide tube 240 and the second guide tube 250 and is guided into the first space 220 through the first guide hole 234a.

[0073] The ends of the first guide tube 240 and the second guide tube 250 do not contact the inner side of the third space 224. The longitudinal sides of the first guide tube 240 and the second guide tube 250 are parallel to and spaced apart from the bottom side 224a of the third space 224, thus having the effect that foreign substances such as water that drip from the first guide tube 240 to the bottom side 224a and remain in the third space 224 cannot flow back into the second guide tube 250.

[0075] refer to Figures 7 to 9 The second space 222 includes a first internal space 270 communicating with the second guide hole 230a, a second internal space 271 communicating with the discharge port 223, and a third internal space 272 positioned between the first internal space 270 and the second internal space 271. A first internal partition 273 is formed between the first internal space 270 and the second internal space 271, a second internal partition 274 is formed between the second internal space 271 and the third internal space 272, and a third internal partition 275 is formed between the third internal space 272 and the first internal space 270. A first internal hole 276 is formed through the third internal partition 275, and a second internal hole 277 is formed through the second internal partition 274.

[0076] A filter 260 is disposed in the first internal space 270 and filters out the gas flowing into the first internal space 270 through the second guide hole 230a. The gas filtered out by the filter 260 moves to the third space 272 through the first internal hole 276. The door member 280 is configured to adjust the opening area of ​​the first internal hole 276.

[0077] The door component 280 includes: a rotating shaft 282 mounted on a first side of a third internal partition 275; a rotating plate 284 formed in a plate shape to cover a first internal hole 276, into which the rotating shaft 282 is inserted and which has an opening 284 on the first side; and a knob 286 having a first side connected to the rotating shaft 282 and a second side disposed outside the body 210 through the body 210. The knob 286 is configured to be easily gripped and rotated by a user. Rotating the knob 286 moves the opening 284a to face or not face the first internal hole 276, thereby opening or closing the first internal hole 276. That is, when the rotating plate 284 is rotated by rotating the knob 286 and the first side of the rotating plate 284 to which the opening 284a is formed is positioned to face the first internal hole 276, the first internal hole 276 is opened by the opening 284a. Conversely, when the second side of the rotating plate 284, where the opening 284a is not formed, is positioned to face the first internal hole 276, the first internal hole 276 is closed by the second side of the rotating plate 284.

[0078] An opening 284a is formed in an arc shape along the circumference of the rotating plate 284. The width of the opening 284a increases from a first side to a second side. The first side of the opening 284a is smaller than the first internal hole 275, and the second side of the opening 284a is the same size as the first internal hole 276. Therefore, when the first side of the opening 284a is positioned facing the first internal hole 276, the size opening to the outside of the first internal hole 276 is smaller than the entire size of the first internal hole 276. However, when the second side of the opening 284a is positioned facing the first internal hole 276, the size opening to the outside of the first internal hole 276 is relatively large, corresponding to the entire size of the first internal hole 276. Therefore, the opening area of ​​the first internal hole 276 is adjusted according to the position of the opening 284a facing the first internal hole 276.

[0079] The operation of a fluid storage and fume extraction device for laparoscopic surgery according to a second embodiment of the present invention is then described.

[0080] Figure 10 This is a schematic view illustrating the flow path of fluid into a fluid storage and fume extraction device for laparoscopic surgery according to a second embodiment of the invention. Figure 11 It is along Figure 10 The cross-sectional view taken by line C-C'.

[0081] refer to Figures 10 to 11 The laparoscopic cannula's discharge portion (not shown) and the connecting protrusion 221a are connected to each other via a connecting conduit (not shown). In this state, the user rotates the door component 280 to open the first internal hole 276 to the third internal space 272.

[0082] Then, the fluid flowing into the inlet 221 through the connecting protrusion 221a is guided into the third space 224 through the first guide pipe 240. The fluid condensed due to the temperature difference and the moisture contained in the water remain in the third space 224. Gas moving into the third space 224 moves through the space between the first guide pipe 240 and the second guide pipe 250 and is guided into the first space 220 through the first guide hole 234a. Gas in the fluid guided into the first space 220 moves into the first internal space 270 through the second guide hole 230a. Gas moving into the first internal space 270 through the second guide hole 230a is filtered out by the filter 260 and moves into the third internal space 272 through the first internal hole 276. Gas moving into the third space 272 moves into the second internal space 271 through the second internal hole 277. Gas moving into the second internal space 271 is finally discharged into the outlet 223. The discharge port 223 has a discharge protrusion 223a, and the gas suction device S is arranged at the discharge protrusion 223a, so the gas discharged from the second internal space 271 to the discharge port 223 is automatically discharged by the suction device S.

[0083] While the present invention has been described above with reference to embodiments, the invention is not limited to these embodiments, and it will be apparent to those skilled in the art that the invention can be modified and altered in various ways within its scope. Furthermore, if such modifications and alterations fall within the scope of the claims, they should be interpreted as being included in the present invention.
