Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to a puncture catheter system. Background Technology

[0002] Laparoscopic surgery requires the creation of a pneumoperitoneum in the abdomen. CO2 gas is then introduced into the pneumoperitoneum via a puncture device. This device typically needs both an inlet and an outlet tube for CO2 gas to flow in and out. The outlet tube also serves as a drainage tube to remove gas and fluid impurities during the procedure, while maintaining stable pressure within the pneumoperitoneum, i.e., a stable pneumoperitoneum space.

[0003] In existing puncture devices, the inlet and outlet pipes form a gas circulation system, within which CO2 flows. However, due to the high humidity inside the gas chamber, the CO2 returning to the outlet pipe has a high humidity and cannot be used directly. Therefore, a corresponding filtration and drying device is required for gas treatment. The gas circulation system needs to have multiple functional structures for heating, filtration, and drying, which results in a large number of functional modules, a complex structure, and low gas recovery and utilization efficiency.

[0004] Therefore, it is necessary to improve the existing gas processing system to solve the technical problems of complex gas path structure and low gas recovery and utilization efficiency. Summary of the Invention

The outer side wall of the main housing is provided with a locking groove corresponding to the position of the locking block, and the locking block is engaged and connected in the locking groove.

[0019] Optionally, the heating assembly includes a sleeve fitted over the air intake pipe, a heating wire connected to the sleeve, the heating wire extending into the air intake pipe to heat the cold gas inside the air intake pipe to a preset temperature.

[0020] Optionally, a drug dosing and humidifying atomizing component is provided between the heating component and the puncture head, and one end of the drug dosing and humidifying atomizing component is connected to the air intake pipe.

[0021] Optionally, the puncture head is provided with a pressure measuring channel, an air inlet channel, and an exhaust channel, wherein the air inlet channel and the exhaust channel are respectively connected to the air inlet pipe and the exhaust pipe;

[0034] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0035] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] This invention provides a puncture catheter system, including a puncture head 1 and a catheter assembly 2. The catheter assembly 2 includes an air inlet pipe 21 and an air outlet pipe 22, and a cooling assembly 3 is provided on the catheter assembly 2. The cooling assembly 3 includes a main housing 31, and a partition assembly 32 is provided inside the main housing 31. A first chamber 311 and a second chamber 312 are formed on both sides of the partition assembly 32, and the first chamber 311 and the second chamber 312 are respectively connected to the air inlet pipe 21 and the air outlet pipe 22. An air source assembly 9, a gas circulation module 4, and an air pump are provided at the end of the catheter assembly 2 away from the puncture head 1.

[0038] The partition assembly 32 includes a plurality of inclined panels 321 connected in sequence, with any two adjacent inclined panels 321 arranged at a preset angle; the wavy partition assembly 32 can improve the heat conduction surface.

[0039] Within the cooling assembly 3, cold gas from the intake pipe 21 enters the first chamber 311, and hot gas from the exhaust pipe 22 enters the second chamber 312. The cold gas in the first chamber 311 and the hot gas in the second chamber 312 exchange heat along the partition assembly 32.

[0040] It should be noted that the cold gas in the first chamber 311 and the hot gas in the second chamber 312 exchange heat. The effect is that the hot gas in the second chamber 312 can be cooled and precipitate water droplets, while the heat in the second chamber 312 is transferred to the first chamber 311, thereby increasing the gas temperature in the first chamber 311. This achieves the effect of preheating the cold gas in the intake pipe 21, so as to reduce the heating process of the subsequent heating component 6, further simplify the gas processing process, and reduce energy consumption.

[0041] The working principle of this invention is as follows: During operation, one end of the puncture head 1 is inserted into the pneumoperitoneum, and cold gas is introduced from one end of the air inlet pipe 21. After gas treatment, the puncture head 1 enters the pneumoperitoneum for treatment. The waste gas with temperature inside the pneumoperitoneum flows out through the exhaust pipe 22 into the cooling assembly 3. The cold gas in the air inlet pipe 21 enters the first chamber 311, and the hot gas in the exhaust pipe 22 enters the second chamber 312. The cold gas in the first chamber 311 and the hot gas in the second chamber 312 exchange heat along the partition assembly 32, wherein the partition assembly 32 includes several inclined... The inclined panel 321 forms a wave structure, which helps to increase the heat exchange area between the two chambers and improve the heat exchange efficiency. The discharged hot gas is cooled by the cooling component 3, causing some of the water vapor to condense on the surface of the partition component 32, thereby drying the gas. Compared with the gas treatment system in the prior art, this puncture catheter system further enhances the heat exchange efficiency of the system through the optimized design of the partition component 32, including its preset angle and inclined form. This puncture catheter system not only provides a highly efficient treatment effect, but also simplifies the waste gas treatment process and improves the gas recovery and utilization efficiency.

[0042] In this embodiment, the partition assembly 32 includes a heat-conducting plate 322, which is disposed on one end face of the inclined panel 321 facing the second chamber 312; wherein, the heat-conducting plate 322 is a metal plate.

[0043] It should be noted that, in combination Figure 1 and Figure 3 As shown, the surface of the partition assembly 32 in this solution is provided with a heat-conducting plate 322 made of metal. The metal material has good thermal conductivity, which is conducive to the transfer of gas heat in the second chamber 312 to the first chamber 311. At the same time, since the metal has a condensation effect, it is conducive to the precipitation of water droplets on the surface of the heat-conducting plate 322, thereby reducing the humidity of the exhaust gas.

[0044] Furthermore, a bending portion 323 is integrally provided between two adjacent inclined panels 321. The bending portion 323 is a plastic deformation portion capable of elastic deformation. An opening groove 313 is provided on the side wall of the main housing 31 near the second chamber 312. A pressing plate 33 is slidably connected to the opening groove 313. One end of the partition assembly 32 is connected to the inner side wall of the main housing 31, and the other end is connected to the pressing plate 33. Driving the pressing plate 33 to move inward can compress the partition assembly 32 to open the opening groove 313.

[0045] As a preferred embodiment, this solution employs an optimized design for the partition assembly 32 and provides a corresponding pressing plate 33 on the main housing 31 to adjust the overall height of the partition assembly 32. By pressing the pressing plate 33 inward, the partition assembly 32 is compressed inward. During this compression, the bent portion 323 undergoes elastic deformation, causing adjacent inclined panels 321 to move closer together, compressing the space between them. This facilitates the falling of water droplets condensed on the surface of the inclined panels 321, allowing for the collection of internal water droplets.

[0046] When the partition assembly 32 is compressed, the opening slot 313 opens, allowing the liquid in the second cavity to be discharged. Since the air inlet pipe 21 and the air outlet pipe in this design are both located within the gas circulation system, excess liquid inside needs to be periodically drained. After the drainage is completed, the pressure plate 33 is reset by the elastic action of the partition assembly 32. In this design, the opening slot 313 is opened or closed by setting an elastically opening pressure plate 33.

[0047] In this embodiment, a limiting groove 314 is provided on the side wall of the opening groove 313, and a guide slope 315 is provided on the side wall of the limiting groove 314; the pressing plate 33 is snapped into the limiting groove 314 and abuts against the guide slope 315; a sealing plate 34 is provided in the opening groove 313, and a locking block 341 is provided on at least one side of the sealing plate 34; a locking groove 316 is provided on the outer side wall of the main housing 31 corresponding to the position of the locking block 341, and the locking block 341 is engaged and connected in the locking groove 316.

[0048] Combination Figure 4 As shown, in this scheme, the pressing plate 33 is limited by the limiting groove 314, which restricts its sliding stroke. That is, the pressing plate 33 can only move within the cavity of the main housing 31. A guide slope 315 is provided to guide the pressing plate 33 to facilitate its sliding. During the process of the partition assembly 32 pushing the pressing plate 33 to reset, in order to avoid the pressing plate 33 being misaligned and affecting the airtightness, the position of the pressing plate 33 is corrected by setting a slope.

[0049] Preferably, a sealing plate 34 is provided above the pressing plate 33. The opening or closing of the opening is controlled by the sealing plate 34 in conjunction with the pressing plate 33. That is, when drainage is not required, the sealing plate 34 blocks the opening groove 313 and a snap-fit ​​structure is provided to fix the sealing plate 34 to prevent accidental opening. When drainage is required, the snap-fit ​​part is deformed to disengage from the snap-fit ​​state with the slot 316, thereby removing the sealing plate 34. The pressing plate 33 is then pressed to open the opening groove 313 to facilitate drainage.

[0050] Specifically, the engagement between the card block 341 and the card slot 316 in this solution is a conventional snap-fit ​​connection, such as the snap-fit ​​structure of a detachable battery back cover, where the card block 341 can be disengaged from the card slot 316 by deformation.

[0051] In this embodiment, an end cap assembly 35 is provided on each of the two end faces of the main housing 31, and the two ends of the partition assembly 32 are respectively attached to the end cap assembly 35; the end cap assembly 35 is provided with a first connector 36 and a second connector 37, the two ends of the first connector 36 are respectively connected to the intake pipe 21 and the first chamber 311, and the two ends of the second pipe are respectively connected to the exhaust pipe 22 and the second chamber 312. The intake pipe 21 and the exhaust pipe 22 are accessed through the connectors of the end cap assembly 35.

[0052] In this embodiment, the duct assembly 2 is provided with a filter assembly 5 and a heating assembly 6 in sequence along the air intake direction of the air intake pipe 21, and the cooling assembly 3 is disposed between the filter assembly 5 and the heating assembly 6; the filter assembly 5 is used to filter the cold gas in the air intake pipe, and the heating assembly 6 is used to heat the cold gas in the air intake pipe to a preset temperature.

[0053] Specifically, the heating component 6 includes a sleeve fitted outside the intake pipe, with a heating wire connected to the sleeve. The heating wire extends into the intake pipe to heat the cold gas inside the intake pipe to a preset temperature.

[0054] Furthermore, a drug-injection and humidification atomizing component 7 is provided between the heating component 6 and the puncture head 1. One end of the drug-injection and humidification atomizing component 7 is connected to the air intake pipe 21. Through the drug-injection and humidification atomizing component 7, the required therapeutic drugs can be added into the air intake pipe 21. Under the action of gas pressure, the therapeutic drugs are driven to be sprayed along the lower end of the puncture head 1 to the preset body position, thereby achieving the effect of drug treatment. The operating principle of the drug-injection and humidification atomizing component 7 is as follows: it includes a drug injection channel and an atomizing element built into the air intake pipe 21. By adding liquid drugs or solutions into the drug injection channel, the atomizing element forms atomized drugs, which act on the preset site in the pneumoperitoneum to enhance the treatment effect.

[0055] In this embodiment, the puncture head 1 is provided with a pressure measuring channel 11, an air intake channel 12 and an exhaust channel 13, the air intake channel 12 and the exhaust channel 13 are respectively connected to the air intake pipe 21 and the exhaust pipe 22; a window portion 14 connected to the pressure measuring channel 11 is provided on the side wall of the puncture head 1, a temperature sensor 15 is installed in the window portion 14, and a pressure measuring component 16 is connected to one end of the pressure measuring channel 11.

[0056] It should be noted that, in order to enhance the monitoring of various components of the system, this puncture tube system uses a temperature sensor 15 installed at the front end of the puncture head 1 to detect the temperature inside the pneumoperitoneum, and a pressure measuring channel 11 connected to the pressure measuring component 16 to monitor the internal air pressure of the pneumoperitoneum in real time. This air pressure can also reflect the pressure situation within the gas circulation system. A corresponding control module 8 is provided to control the operation of each component and to present the detection data to the user in real time.
