Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices and relates to a pipeline and a smoke exhaust filter for a pneumoperitoneum system. Background Art

[0002] When performing various laparoscopic surgeries, it is necessary to establish a surgical space, and gas needs to be perfused into the abdominal cavity to have a good surgical field of view for the surgeon's observation and operation. Currently, carbon dioxide gas is the main gas selected for establishing and maintaining pneumoperitoneum. A pneumoperitoneum machine is a basic auxiliary device in the endoscopic system, and its function is to inject or expel carbon dioxide gas in the surgical area of the patient to maintain the pneumoperitoneum space and ensure a good surgical field of view.

[0003] There are many pneumoperitoneum machines on the market that only have the function of establishing pneumoperitoneum, and most other functions (such as smoke exhaust) are missing and need to be used in conjunction with other devices. Moreover, since the temperature of the carbon dioxide gas output by the pneumoperitoneum machine is generally lower than the normal body temperature of the human body, especially when a large flow of carbon dioxide gas is input into the patient's abdominal cavity, it will absorb a large amount of human body heat, causing discomfort to the patient during and after the surgery, increasing the probability of tissue damage and inflammatory reactions, and the patient's postoperative recovery process is longer, increasing the patient's pain. At the same time, when the carbon dioxide gas, which is much lower than the normal body temperature of the human body, enters the abdominal cavity, it will cause the water vapor in the pneumoperitoneum to liquefy and condense on the laparoscope lens, affecting the surgeon's surgical field of view, increasing the number of lens cleaning times, and prolonging the operation time, so there is a certain room for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to address the above problems existing in the prior art and propose a pipeline and a smoke exhaust filter for a pneumoperitoneum system.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A pipeline for a pneumoperitoneum system includes:

[0006] An injection pipe, the injection pipe includes a main pipe body and a wire. A heating wire and a sensor are arranged inside the main pipe body. The end of the wire is connected with a plug, and both the heating wire and the sensor are electrically connected to the wire.

[0007] Preferably, the main pipe body includes a tee joint, a first pipe portion, and a second pipe portion. The tee joint includes a first interface, a second interface, and a third interface. The first pipe portion is connected to the first interface, the second pipe portion is connected to the second interface, and the wire is connected to the third interface.

[0008] Preferably, it further includes a smoke exhaust pipe, and the smoke exhaust pipe and the injection pipe form a double-pipe structure.

[0009] Preferably, it further includes a tracheal connector, and both the exhaust pipe and the injection pipe are connected to the tracheal connector.

[0010] Preferably, the number of the heating wires is at least two.

[0011] There is also provided a smoke exhaust filter, which includes the pipeline for the pneumoperitoneum system described above, and further includes a smoke exhaust filter. The smoke exhaust filter has an air inlet interface and an air outlet interface. The injection pipe is connected to the air outlet interface, and the exhaust pipe is connected to the air inlet interface.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The heating wire and the sensor are integrated in the injection pipe. The heating wire and the sensor are electrically connected to the plug through a wire, so as to facilitate power taking. In this way, the gas entering the abdominal cavity can be heated to maintain a gas temperature close to the human body temperature, and the discomfort of the patient caused by directly injecting cold gas into the abdominal cavity or potential body temperature drop can be reduced, improving the safety and comfort of the operation. The heating effect is better and the temperature is easier to control.

[0014] 2. The gas enters the second pipe part through the three-way joint from the first pipe part and is then transported to the human abdomen. The heating wire and the sensor take power through the plug, so that the plug can avoid the injection pipe. This design not only optimizes the gas flow path, but also makes the electrical connection ends of the heating wire and the sensor avoid the injection pipe.

[0015] 3. An exhaust pipe is also added. The exhaust pipe and the injection pipe work in parallel. They are independent of each other but form a unified whole. The innovation of this design lies in that it not only solves the problems of gas heating and temperature control in the pneumoperitoneum system, but also solves the problem of the emission of smoke and harmful gases generated during the operation.

Detailed implementation manners

[0021] The following are specific embodiments of the present invention and, in combination with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0022] As Figures 1-4 shown, a pipeline for a pneumoperitoneum system includes: a gas injection tube 100, the gas injection tube 100 includes a main pipe body 110 and a wire 140, a heating wire 120 and a sensor 130 are arranged in the main pipe body 110, a plug 141 is connected to the end of the wire 140, and both the heating wire 120 and the sensor 130 are electrically connected to the wire 140.

[0023] This design integrates the heating function and the monitoring function into the gas injection tube 100 to improve the safety of the operation and the comfort of the patient. Specifically, the gas injection tube 100 is divided into two parts: the main pipe body 110 and the wire 140. Inside the main pipe body 110, a heating wire 120 and a sensor 130 are installed. The function of the heating wire 120 is to preheat the carbon dioxide gas injected into the patient's abdominal cavity during the operation to ensure that the gas is close to the human body temperature and avoid the discomfort of the patient, the risk of shivering and the possible decrease in body temperature caused by the direct injection of low-temperature gas. The sensor 130 may be used to monitor the gas temperature or other key parameters to ensure that the heating effect is stable and controllable.

[0024] The end of the wire 140 is equipped with a plug 141, and the sensor 130 is connected with a connecting wire, which enables the connecting wires of the heating wire 120 and the sensor 130 to be connected to the plug 141 through the wire 140, facilitating power supply and signal transmission. This design simplifies the operation and makes the whole system more compact and easy to maintain.

[0025] Integrating the heating wire 120 and the sensor 130 in the gas injection tube 100, and electrically connecting the heating wire 120 and the sensor 130 to the plug 141 through the wire 140, thus facilitating power taking, can heat the gas entering the abdominal cavity to maintain a gas temperature close to the human body temperature, and reduce the discomfort of the patient or the potential decrease in body temperature caused by the direct injection of cold gas into the abdominal cavity, improve the safety and comfort of the operation, and have a better heating effect and better temperature control.

[0026] As Figure 1As shown, on the basis of the above embodiments, the main pipe body 110 includes a three-way joint 111, a first pipe portion 112, and a second pipe portion 113. The three-way joint 111 includes a first interface, a second interface, and a third interface. The first pipe portion 112 is connected to the first interface, the second pipe portion 113 is connected to the second interface, and the wire 140 is connected to the third interface.

[0027] The three-way joint 111 serves as a central hub with three interfaces. The first pipe portion 112 and the second pipe portion 113 are connected and communicated through the three-way joint 111. The wire 140 is connected to the third interface to block the third interface, so that gas will not leak from the third interface. Specifically, the gas enters the second pipe portion 113 from the first pipe portion 112 through the three-way joint 111 and then is transported to the human abdomen. The heating wire 120 and the sensor 130 obtain power through the plug 141, which can avoid the injection tube 100. Such a design not only optimizes the gas flow path but also keeps the electrical connection ends of the heating wire 120 and the sensor 130 away from the injection tube 100.

[0028] As Figures 1-4 shown, on the basis of the above embodiments, it further includes an exhaust pipe 200, and the exhaust pipe 200 and the injection tube 100 form a double-pipe structure.

[0029] It should be supplemented that a clear surgical field of view is the key to the safety of laparoscopic surgery. However, instruments such as monopolar electrosurgical knives, ultrasonic knives, and vascular ligation used in laparoscopic surgery will more or less generate smoke. The smoke not only hinders the smooth progress of the surgery, affects the surgical field of view, but also prolongs the operation time. During the use of electrosurgical equipment in surgery, different degrees of smoke, aerosol, and various harmful gases will inevitably be generated.

[0030] For the above reasons, an exhaust pipe 200 is added in this design. The exhaust pipe 200 and the injection tube 100 work in parallel, being independent of each other but forming a unified whole. The innovation of this design lies in that it not only solves the problems of gas heating and temperature control in the pneumoperitoneum system but also solves the problem of the emission of smoke and harmful gases generated during the operation.

[0031] On the basis of the above embodiments, it further includes a tracheal joint 300, and both the exhaust pipe 200 and the injection tube 100 are connected to the tracheal joint 300.

[0032] On the basis of the above embodiments, the number of heating wires 120 is at least two. The arrangement of multiple heating wires 120 can be more evenly distributed in the main pipe body 110 of the injection tube 100 to ensure that the carbon dioxide gas injected into the abdominal cavity can be heated sufficiently and evenly. This can effectively avoid the existence of local overheating or cold and hot spots, making the entire gas temperature more consistent and closer to the human body temperature.

[0033] As Figures 1-4 shown, a smoke exhaust filter is also provided, which includes a pipeline for a pneumoperitoneum system, and further includes a smoke exhaust filter 400. The smoke exhaust filter 400 has an air inlet interface 410 and an air outlet interface 420. The injection tube 100 is connected to the air outlet interface 420, and the smoke exhaust tube 200 is connected to the air inlet interface 410.

[0034] The smoke exhaust tube 200 discharges the smoke into the smoke exhaust filter 400 for filtering, and the filtered gas is preheated by the injection tube 100 and then reinjected into the patient's abdomen, thereby constructing a circulation system.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly.

[0036] In addition, in the present invention, descriptions such as "first", "second", "one", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0037] In the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
