Abstract
Description
Technical Field
[0001] This application relates to the field of medical cable technology, and in particular to a pneumoperitoneum heating wire and a pneumoperitoneum tube. Background Technology
[0002] An insufflator is a specialized device for establishing and maintaining pneumoperitoneum in laparoscopic surgery. The insufflator mainly consists of an inlet tube, a main unit, an outlet tube, and an insufflation needle. It is used to establish artificial pneumoperitoneum by mechanically pressurizing and inflating the abdominal wall to separate the abdominal wall from the organs, providing sufficient operating space for the surgery and avoiding damage to organs when the trocar is inserted into the abdominal cavity.
[0003] Modern pneumoperitoneum machines require heating the carbon dioxide gas injected into the abdominal cavity to ensure that the gas temperature is approximately the same as the ambient temperature inside the cavity. The output gas of the pneumoperitoneum machine uses an instantaneous constant-temperature heating method, which maintains the gas temperature entering the abdominal cavity at 30–37°C.
[0004] However, the key components of the current gas heating device for insufflator machines are PTC heat generators and thermistors. A PTC is a special semiconductor device that simultaneously generates heat and controls temperature. This device heats the carbon dioxide gas at the front end of the insufflator tube, that is, it heats the carbon dioxide gas before it enters the insufflator tube. However, this heating method has some problems. During the transmission of carbon dioxide gas within the insufflator tube, heat is lost due to environmental factors, and the amount of heat lost varies depending on the ambient temperature. This may result in a lower temperature of the carbon dioxide in the insufflator, leading to low heating efficiency. Increasing the temperature output would increase energy consumption, which is not energy-efficient or environmentally friendly. Summary of the Invention

[0006] One embodiment of this application discloses a pneumoperitoneum heating wire, including: a sheath, a heating wire group, and a signal wire group, wherein the heating wire group and the signal wire group are surrounded by the flat sheath.

[0027] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0028] It should be noted that the pneumoperitoneum heating wire is a type of wire used for heating the pneumoperitoneum tube of a pneumoperitoneum machine. It mainly heats itself and then transfers the heat to the pneumoperitoneum tube, which in turn heats the gas inside the pneumoperitoneum tube and introduces it into the body cavity. The signal wire transmits the temperature sensing and heating probe signals of the pneumoperitoneum device in real time.
[0029] Reference Figure 1 This application illustrates an embodiment of a pneumoperitoneum heating wire, comprising: a sheath 3, a heating wire group 1, and a signal wire group 2. The heating wire group 1 and the signal wire group 2 are surrounded by the flat sheath 3. The heating wire group 1 and the signal wire group 2 are arranged in parallel, and the cores of the heating wire group 1 and the signal wire group 2 are arranged in the same plane. The flat sheath 3 has an asymmetrical thickness structure relative to the two sides of the parallel heating wire group 1 and the signal wire group 2. The thinner side is in close contact with the pneumoperitoneum tube, and the thicker side faces outward from the pneumoperitoneum tube.
[0030] This application proposes a heating wire for pneumoperitoneum, which combines a heating wire group 1 and a signal wire group 2 into a single unit component. The heating wire itself can generate heat, and the heat is transferred to the gas inside the pneumoperitoneum tube. The signal wire group 2 and the heating wire group 1 are arranged in parallel and are surrounded by a flat sheath 3, forming a shape that is thick on one side and thin on the other. The thin side is in close contact with the pneumoperitoneum tube to improve heating efficiency, while the thick side faces outward to ensure that the wire is not easily damaged and to ensure that the wire has a flat appearance and is easy to wrap around the surface of the pneumoperitoneum tube for post-processing.
[0031] The following will further describe a pneumoperitoneum heating wire and a pneumoperitoneum tube in this exemplary embodiment.
[0032] In one embodiment of this application, a pneumoperitoneum heating wire includes: a sheath 3, a heating wire group 1, and a signal wire group 2. The heating wire group 1 and the signal wire group 2 are surrounded by the flat sheath 3. The heating wire group 1 and the signal wire group 2 are arranged in parallel, and the cores of the heating wire group 1 and the signal wire group 2 are arranged in the same plane. The flat sheath 3 has an asymmetrical thickness structure relative to the two sides of the parallel heating wire group 1 and the signal wire group 2. The thinner side is close to the pneumoperitoneum tube, and the thicker side faces the outside of the pneumoperitoneum tube.
[0033] This application proposes a pneumoperitoneum heating wire that combines a heating wire assembly 1 and a signal wire assembly 2 into a single unit component. This allows the heating wire itself to heat up, and the heat is simultaneously transferred to the gas inside the pneumoperitoneum tube. The signal wire assembly 2 and the heating wire assembly 1 are arranged in parallel and are surrounded by a flat sheath 3, forming a shape that is thicker on one side and thinner on the other. Figure 1 and Figure 2 As shown, side A is thicker, while side B is thinner. The thinner side is in close contact with the pneumatic tube to improve heating efficiency, while the thicker side faces outward to ensure that the wire is not easily damaged and to ensure that the wire has a flat appearance and is easy to wrap around the surface of the pneumatic tube for back-end pasting processing.
[0034] In one embodiment of this application, the heating wire group 2 consists of at least two heating wires; the signal wire group 2 consists of at least three signal wires; wherein the heating wire 10 and the signal wire 20 are arranged alternately in parallel, forming a structure in which the heating wire 10 and the signal wire 20 are adjacent to each other.
[0035] As an example, such as Figure 1 As shown, the heating wire 10 and the signal wire 20 are arranged in the following order: one heating wire 10, one signal wire 20, one heating wire 10, one signal wire 20, and one signal wire 20; or they can be arranged as follows: Figure 2The arrangement shown is specifically a signal wire 20, a heating wire 10, a signal wire 20, a heating wire 10, and a signal wire 20; the arrangement of the heating wire 10 and the signal wire 20 in this application includes, but is not limited to, the two arrangement methods mentioned above; the arranged wire group is extruded through an extrusion process to form a sheath 3 with one side thick and the other side thin. The thin side faces inward to contact the gas cylinder wall, ensuring high efficiency of heat transfer, while the thick side faces outward. This thickness can ensure that the outer sheath of the wire can resist external forces such as external pressure from damaging the internal signal wire group 2 and heating wire group 1, ensuring the durability of the wire covering the gas cylinder; in addition, the signal wire 20 and the heating wire 10 are arranged in parallel to ensure that the appearance of the extruded wire sheath is flat and beautiful.
[0036] In one embodiment of this application, the sheath 3 is made of silicone elastomer.
[0037] Furthermore, the hardness of the aforementioned sheath 36 is Shore 30 to 70 A.
[0038] The aforementioned sheath 3 is made of silicone elastomer material. In this application, a hardness of Shore (a standard for material hardness) 50A is preferred, which gives the pneumoperitoneum heating wire good flexibility, resistance to chemical disinfection, heat resistance, the ability to be bent at will, comfortable use, and easy cleaning.
[0039] In one embodiment of this application, the heating wire 10 has a structure consisting of a heating wire core 11 and a first insulating layer 12 made of external extruded insulating material. In this application, the heating wire core 11 is preferably a stranded structure of nickel-copper alloy wires.
[0040] The aforementioned heating wire core 11 is stranded with nickel-copper alloy. On the one hand, this ensures that the heating wire can generate heat when a suitable current passes through it. On the other hand, by stranding multiple nickel-copper alloy wires to form the heating wire core, it has a certain degree of flexibility and bending resistance.
[0041] In one embodiment of this application, the signal conductor 20 has a structure of a central conductor 21 and a second insulating layer 22 made of external extruded insulating material.
[0042] Furthermore, the central conductor is a silver-copper alloy conductor, specifically, the silver-copper alloy conductor is configured as a stranded structure of multiple silver-copper alloy wires.
[0043] The center conductor 21 of the aforementioned signal conductor 20 uses a stranded silver-copper alloy to ensure the thermal flexibility and bending resistance of the wire. The aforementioned heating wire core 11 uses a stranded nickel-copper alloy to ensure that the heating wire can generate heat when a suitable current passes through it, and has a certain degree of flexibility and bending resistance.
[0044] In one embodiment of this application, a pneumoperitoneum tube is also disclosed, including a tube body and the aforementioned pneumoperitoneum heating wire; wherein, the thinner side of the sheath 2 of the pneumoperitoneum heating wire is attached to the tube body; in use, the heating wire group 1 of the pneumoperitoneum heating wire is electrically connected to the heating probe of the pneumoperitoneum machine; the signal wire group 2 is electrically connected to the temperature sensing probe and controller of the pneumoperitoneum machine.
[0045] The two heating wires 10 and three signal wires 20 are arranged in parallel to ensure a flat and aesthetically pleasing finished sheath. The sheath 3 is extruded to ensure that one side is thicker than the other, guaranteeing efficient heat transfer by ensuring the thinner side of the sheath 3 adheres to the thicker side of the insufflation tube, while the thicker side protects the internal heating wire group 1 and signal wire group 2. The heating wire group 1 is connected to the heating probe of the insufflation machine, and the controller controls the heat generated by the wires to maintain the temperature of the gas inside the insufflation tube. The signal wire group 2 is connected to the temperature sensor and controller of the insufflation machine, and by detecting the temperature and controlling the heat generated by the heating wires, it ensures that the insufflation heating wires can work normally and effectively.
[0046] The beneficial effects of this application also include that, by fitting the insulated tube with the insulated heating wire, during the transmission of carbon dioxide gas in the insulated tube, on the one hand, it can ensure that the temperature of the carbon dioxide in the insulated tube is not too low, thus improving the heating efficiency; on the other hand, it will not heat excessive heat, and due to the high heating efficiency, it has a certain energy-saving effect, which is beneficial to environmental protection.
