DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0029] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, a drainage puncture device for abdominal surgery includes a puncture tube 6, the upper end of the puncture tube 6 is connected to a drainage nozzle 21, the lower end of the puncture tube 6 is connected to a puncture head 61, the outer side of the puncture tube 6 is sleeved with an inner sleeve 10 and an outer sleeve 1, the top of the inner sleeve 10 is provided with a handle portion 2, a tubular cavity is formed between the outer sleeve 1 and the inner sleeve 10, the upper end of the tubular cavity is closed and a matching rubber sleeve 50 is adjustable in the tubular cavity, the matching rubber sleeve 50 and the upper end of the tubular cavity form a sealed space, and the sealed space is connected to an airtight seal. Valve 22, the matching rubber sleeve 50 is connected to a rubber sleeve 52, and the rubber sleeve 52 extends to the bottom end of the tubular cavity and is connected to a positioning airbag 5. After the positioning airbag 5 passes through the tubular cavity, it is turned outward and sleeved on the outside of the outer sleeve. A plurality of groups of air guide hoses 51 are evenly distributed between the matching rubber sleeve 50 and the rubber sleeve 52. The end of the air guide hose 51 extends into the positioning airbag 5. A positioning rubber ring 4 is sleeved on the outer sleeve 1. After the positioning airbag 5 is inflated, it is distributed with the positioning rubber ring 4 on the inner and outer sides of the abdominal wall, so that the puncture device is fixed on the abdominal wall.

[0030] Specifically, when using a drainage puncture device to drain the area containing fluid in the abdominal cavity, the depth of the area containing fluid in the abdominal cavity and the thickness of the abdominal wall are first preliminarily detected in conjunction with the puncture tube 6. The position of the rubber sleeve 50 on the inner sleeve 10 is adjusted according to the depth. Then, the outer sleeve 1 is sleeved on the inner sleeve 10, and the rubber sleeve 52 and the positioning airbag 5 at the end are passed through the interior of the outer sleeve 1. After the outer sleeve 1 and the inner sleeve are installed, the rubber sleeve 52 and the positioning airbag 5 extending from the end of the tubular cavity are turned outward and wrapped to the outside of the outer sleeve 1, and the positioning airbag 5 is pushed upward along the outer sleeve 1 so that the rubber sleeve 52 is fully extended. At this time, the distance between the positioning airbag 5 and the end of the puncture tube 6 is equal to the depth of the area containing fluid in the abdominal cavity measured earlier minus the thickness of the abdominal wall. Then, the air valve 22 is combined to inflate the positioning airbag 5, and the positioning rubber ring 4 and the positioning airbag 5 are used to fix the drainage puncture device on the abdominal wall. The puncture head 61 is located at the site of ascites to drain the effusion, and at the same time, drugs can be injected into the surgical site through the drainage nozzle 21.

[0031] It should be noted that before installing the outer sleeve 1, a line can be tied on the positioning airbag 5 in the contracted state so that the line passes through the outer sleeve 1. During the process of mutual connection between the outer sleeve 1 and the inner sleeve 10, the positioning airbag 5 is pulled out of the outer sleeve 1 through the line, so that the rubber sleeve 52 and the positioning airbag 5 are stuck on the inner side of the outer sleeve 1 when the outer sleeve 1 is installed.

[0032] Further, such as Figure 3 As shown, the outer ring of the upper end of the inner sleeve 10 is provided with a connecting thread 11, the top of the outer sleeve 1 cooperates with the connecting thread 11, and the inner sleeve 10 is provided with a limiting ring 12 above the connecting thread 11, and the limiting ring 12 is provided with a sealing ring 13 on the side facing the end of the outer sleeve 1.

[0033] Specifically, the outer sleeve 1 is fixedly installed between the inner sleeve 10 through the connecting thread 11, and the sealing effect of the upper end of the tubular cavity is ensured by the limit ring 12 and the sealing ring 13, thereby ensuring that no air leakage will occur when the tubular cavity is subsequently inflated through the air valve 22, thereby ensuring the reliable opening and positioning of the positioning airbag 5.

[0034] Further, such as Figure 2 、 Figure 4 As shown, the surface of the inner sleeve 10 is evenly provided with anti-slip grooves 100, the matching rubber sleeve 50 is provided with protrusions that cooperate with the anti-slip grooves 100, and the air guide hose 51 passes through the top of the matching rubber sleeve 50 and is connected to the air valve 22.

[0035] Specifically, due to the different thicknesses of the abdominal wall and the depths of the effusion, the height of the positioning airbag 5 relative to the outer sleeve 1 needs to be flexibly adjusted. In order to ensure that the positioning airbag 5 does not slide relative to the outer sleeve 1 before and after adjustment, a protrusion is provided on the inner sleeve 10 so that the rubber sleeve 50 cooperates with the protrusion. The rubber sleeve 52 will also shrink and adhere to the outer wall of the inner sleeve 10 under the action of its own elasticity, and the rubber sleeve 52 and the positioning airbag 5 that pass through the end of the tubular cavity need to be stretched and expanded and then covered on the outer wall of the outer sleeve 1, further ensuring the reliable positioning of the positioning airbag 5 after adjustment.

[0036] Further, such as Figure 2 、 Figure 7 As shown, the handle portion 2 is provided with a puncture control assembly 3, and the puncture control assembly 3 includes a control rod 62 provided on the top of the puncture tube 6, and the outer ring of the control rod 62 is evenly provided with annular protrusions 620. The handle portion 2 is provided with a pressing block 30, and the part of the pressing block 30 located on the inner side of the handle is connected to the connecting flange 36. The inner side of the handle portion 2 is provided with a plug-in column 37, and the connecting flange 36 and the plug-in column 37 are plugged into each other. A return spring 2 38 is provided between the handle portion 2 and the push block 30, a push plate 31 is provided on the push plate 31, a matching hole 39 is provided at the end of the push plate 31, the control rod 62 passes through the matching hole 39 and extends to the top of the handle portion 2, a center tube 32 is provided at the center of the handle portion 2, a positioning plate 33 is provided in the center tube 32, the control rod 62 passes through the positioning plate 33 and is connected to a pressing protrusion 34, and a return spring 1 35 is sleeved on the control rod 62 between the positioning plate 33 and the pressing protrusion 34.

[0037] Specifically, in order to avoid the disadvantage of the puncture head 61 being inserted into the drainage area by mistake, when the puncture head 61 reaches the drainage area, the push plate 31 is driven to move by the pressing block 30, so that the matching hole 39 is disengaged from the annular protrusion 620 on the control rod 62, and the control rod 62 rises under the drive of the return spring 35, thereby driving the entire puncture tube 6 below to rise, so that the puncture head 61 is retracted into the inner sleeve 10, avoiding the puncture head 61 from causing damage to the abdominal cavity during drainage.

[0038] Furthermore, a groove that cooperates with the annular protrusion 620 is provided in the matching hole 39 , and the pressing blocks 30 are symmetrically arranged on both sides of the handle portion 2 .

[0039] Specifically, the groove provided in the mating hole 39 cooperates with the annular protrusion 620 to ensure that the control rod 62 is securely positioned within the mating hole 39, thereby preventing the control rod 62 from slipping between the mating hole 39 during the insertion of the puncture tube 6. The pressing blocks 30 are symmetrically arranged, so that the two sets of push plates 31 and the mating hole 39 intersect to limit the control rod 62, further ensuring the secure positioning of the control rod 62.

[0040] Further, such as Figure 2 、 Figure 8 As shown, a matching piston 66 is provided on the inner side of the puncture tube 6, and a guide hose 65 is provided on the matching piston 66. The guide hose 65 passes through the top of the puncture tube 6 and is connected to the connecting hose 64. The puncture tube 6 is connected to the air valve 22 through the connecting hose 64. A connecting steel wire 63 is provided on the matching piston 66. The connecting steel wire 63 passes through the top of the puncture tube 6 and extends to the outside of the handle part 2. A pull ring is provided at the end of the connecting steel wire 63.

[0041] Specifically, when the amount of fluid in the abdominal cavity is small, the thicker puncture tube 6 cannot completely clear the fluid. The connecting steel wire 63 controls the movement of the matching piston 66 in the puncture tube 6, so that the matching piston 66 moves downward. A small amount of fluid enters the puncture tube 6 and directly enters the connecting hose 64, avoiding excessive air being sucked out during drainage to cause a negative pressure state, thereby avoiding adhesion between the inner wall tissues of the abdominal cavity, and preventing tissue from being adsorbed to the puncture head 61 to block the fluid extraction port.

[0042] Further, such as Figure 6 As shown, a positioning ring 222 is provided on the inner side of the air valve 22 , and the positioning ring 222 is connected to a support spring 221 . A rubber plug 220 is provided between the end of the support spring 221 and the air valve 22 .

[0043] Specifically, when the positioning airbag 5 needs to be inflated, it is directly connected to the air valve 22, and the rubber plug 220 is pushed open by the air pressure to inflate the air valve 22. After the inflation stops, the rubber plug 220 blocks the air valve 22 under the action of the support spring 221 to prevent gas leakage; when the air is deflated, the rubber plug 220 can be directly pushed open.

[0044] Further, such as Figure 2 As shown, the outer wall of the outer sleeve 1 is evenly provided with anti-slip grooves 100, and the positioning rubber ring 4 and the positioning airbag 5 cooperate with the anti-slip grooves 100.

[0045] Specifically, the anti-slip groove 100 is provided on the outer sleeve 1, which can further prevent the positioning rubber ring 4 and the positioning airbag 5 from sliding relative to the outer sleeve 1, ensure the positioning effect of the puncture device relative to the abdominal wall, and prevent the puncture device from sliding axially.

[0046] Further, as shown in Figure 2 The puncture tube 6 and the inner sleeve 10 are provided with a positioning sleeve 60, and the end of the puncture tube 6 and the inner sleeve 10 is provided with a sealing rubber sleeve.

[0047] Specifically, the sealing rubber sleeve is arranged between the end of the puncture tube 6 and the inner sleeve 10, so that the accumulated liquid in the abdominal cavity after the puncture device is placed in the abdominal cavity can be prevented from entering the cavity part between the puncture tube 6 and the inner sleeve 10, further preventing the accumulated liquid from flowing into the handle part 2, and facilitating subsequent disassembly, cleaning and disinfection of the puncture device.

[0048] The working principle of the embodiment of the present application is as follows:

[0049] As shown in Figures 1-8As shown, when a drainage puncture device is needed to drain the area containing fluid in the abdominal cavity, the depth of the area containing fluid in the abdominal cavity and the thickness of the abdominal wall are first preliminarily detected in combination with the puncture tube 6. The position of the rubber sleeve 50 on the inner sleeve 10 is adjusted according to the depth. Then, the outer sleeve 1 is sleeved on the inner sleeve 10, and the rubber sleeve 52 and the positioning airbag 5 at the end are passed through the outer sleeve 1. After the installation between the outer sleeve 1 and the inner sleeve is completed, the rubber sleeve 52 and the positioning airbag 5 extending outward from the end of the tubular cavity are wrapped to the outside of the outer sleeve 1, and the positioning airbag 5 is pushed upward along the outer sleeve 1 so that the rubber sleeve 52 is fully extended. At this time, the distance between the positioning airbag 5 and the end of the puncture tube 6 is equal to the depth of the area containing fluid in the abdominal cavity measured earlier minus the thickness of the abdominal wall. The positioning balloon 5 is then inflated using the air valve 22. The positioning rubber ring 4 and the positioning balloon 5 secure the drainage puncture device to the abdominal wall, with the puncture head 61 positioned at the site of peritoneal effusion for drainage. At the same time, medication can be injected into the surgical site through the drainage nozzle 21. The outer cannula 1 is fixedly mounted between the connecting thread 11 and the inner cannula 10. The upper end of the tubular cavity is sealed by the limiting ring 12 and the sealing ring 13, thereby ensuring that no air leaks occur when the tubular cavity is subsequently inflated through the air valve 22, and that the positioning balloon 5 is reliably deployed and positioned. Due to the different thicknesses of the abdominal wall and the depths of the effusion, the height of the positioning airbag 5 relative to the outer sleeve 1 needs to be flexibly adjusted. In order to ensure that the positioning airbag 5 does not slide relative to the outer sleeve 1 before and after adjustment, a protrusion is provided on the inner sleeve 10 so that the matching rubber sleeve 50 cooperates with the protrusion. The rubber sleeve 52 will also shrink and adhere to the outer wall of the inner sleeve 10 under the action of its own elasticity, and the rubber sleeve 52 passing through the end of the tubular cavity and the positioning airbag 5 need to be stretched and expanded and then covered on the outer wall of the outer sleeve 1, further ensuring the reliable positioning of the positioning airbag 5 after adjustment. To prevent the puncture tip 61 from being misinserted into the drainage area, once the puncture tip 61 reaches the drainage area, the push plate 31 is moved by the pressing block 30, disengaging the mating hole 39 from the annular protrusion 620 on the control rod 62. Driven by the return spring 35, the control rod 62 rises, thereby raising the entire puncture tube 6 below, allowing the puncture tip 61 to retract into the inner cannula 10, thus preventing damage to the abdominal cavity caused by the puncture tip 61 during drainage. When the amount of fluid in the abdominal cavity is low, the thicker puncture tube 6 cannot completely clear the fluid. The connecting wire 63 controls the movement of the mating piston 66 within the puncture tube 6, causing the mating piston 66 to move downward, allowing a small amount of fluid to enter the puncture tube 6 and directly enter the connecting hose 64, thus avoiding excessive air suction during drainage, thereby preventing adhesion between the abdominal wall tissues and preventing tissue adsorption to the puncture tip 61 and blocking the fluid extraction port.
