Definitions
- the present invention relates to a tube with integrated heating element for laparoscopy.
- a moistening agent within the tube, the gas introduced during the laparoscopy is tempered and moistened.
- the present patent application takes the priorities of German prior applications DE102013000492.6 (filing date: 15.1.2013) and DE 1020130100967.6
- Laparoscopy is a medical procedure in which the abdominal cavity and its internal organs can be checked visually.
- small incisions 0.3 - 2 cm
- a trocar which in turn can accommodate an optical device.
- endoscope laparoscope
- the abdomen can be seen.
- diagnostic laparoscopy the abdominal area is only visually inspected; as part of a therapeutic anticipation, operative
- the abdominal cavity is first filled with gas in order to create a pneumoperitoneum.
- gases such as air, nitrogen or carbon dioxide (CO 2 ).
- CO 2 carbon dioxide
- the use of carbon dioxide gas has proven particularly effective. It has been found that it makes sense to heat the injected gas on the one hand and to moisten it on the other, especially in the case of longer laparoscopic interventions.
- the purpose of gas heating is not to cool the patient, nor to avoid a diffuse sensation of pain of the patient, which is probably due to local cooling due to the entry of cold gas.
- Humidification serves to prevent the inner abdominal surfaces from drying out in order to avoid the resulting cooling. Important here is, during the
- German Patent DE 19510710 describes a device which provides a means for adjusting the gas humidity (for example a sponge) and which optionally may contain an additional heating element.
- US 6,068,609 discloses an alternative device having a chamber which on the one hand has a sponge-like material, on the other hand provides a resistance heating.
- the humidification chamber contains a luer-lock connection, which allows the filling of the chamber with water.
- the chamber of US 6,068,609 is introduced by appropriate connections in the gas flow of the insufflator.
- Other prior art forms the writings EP 0827417B1, US 2010/0206308 A1, DE 4331559 A1 and DE 4211986 A1.
- the devices known in the prior art initially have technical disadvantages.
- the chamber arranged on the patient side reduces the manageability of the insufflation tube during the surgical procedure. Due to the size and weight of the chamber, it can disturb the doctor in the nearby operating theater. Furthermore, the humidification rates of the gas at different flow rates are not uniformly high. In particular, the short path of the gas through the chamber prevents optimal humidification at high flow rates.
- the insufflation performance may no longer be sufficient and the pressure in the abdominal cavity can not be maintained.
- the introduction of the additional chamber for humidification of the gas also has a disadvantageous effect on the production costs of the insufflation tube.
- the additional parts required increase the costs considerably.
- the object of the present invention is therefore to provide an improved device for heating and humidifying insufflation gases, which overcomes the disadvantages mentioned.
- the object is achieved by the subject matter of the claims, ie an insufflation tube with integrated heating and humidifying.
- the tube according to the invention in this case contains a heating element which, for example in the form of resistance heating, can heat the insufflation gas (for example CO 2 ).
- the heating power of the heater must be adjustable, depending on the current
- the hose according to the invention can to a
- the probe which is preferably positioned at the patient end of the tube.
- the probe can be used to ensure that the air flowing through the hose does not exceed a temperature of 37 ° C on the outlet side.
- a heating wire is placed in the insufflation tube for heating.
- the wire may be loosely inserted within the tube, but it may also be attached to one or more points on the tube wall.
- To increase the power of the heating wire can be coiled inside the hose. The resulting extension of the heating wire leads to increase the surface and thus at a constant resistance or adjusted voltage to increase the heating power.
- the heating wire can also be mounted outside of the hose.
- it may for example be cast in the tube wall.
- the tube can be made of any material that is commonly used in the medical field, such as PVC, PUR, TPU or silicone. Typical hose diameters in this range are 6-14 mm.
- the heating wire may consist of any conductive materials, in particular metals and metal alloys, for example iron, nickel, chromium or copper.
- the diameter of the wire is for example 0.25 - 1 mm.
- the wire is used in the form of a helix with a diameter of 3-4 mm.
- the wire has a length of 50 cm - 10 m in common uses. With an applied voltage of 5-25 V, a heat output of 5-50 W can be achieved.
- the heating wire has an electrical insulation to avoid short circuits. If the heating wire is to be integrated into the hose wall or is located outside the hose, naturally higher heating capacities are required than if the heating wire is inside the hose.
- a humidifying material is also positioned. It is a porous material which is able to absorb liquid, especially water.
- This moistening material may, for example, enclose the heating element so that the heating element has direct contact with the moistening material over substantially its entire length.
- the moistening material is positioned directly against the inner tube wall so that substantially full-surface contact of the heated tube wall with the moistening material is established.
- Hose of for example 1 - 4 meters (preferred length 2.5 - 3.5 m) take place.
- the material can also be installed over a shorter distance (for example, only 40-60 cm) in the hose.
- the hose part with heating and moistening device is preferably positioned on the patient-side end of the hose.
- the hose part with heating and humidifying device should have at least 40 cm in length and at least 15% of the total hose length. The more distance the humidifying material has to the tube, the less back pressure the tube will produce during insufflation. The distance can also be greatly reduced. This increases depending on the type of material used, the back pressure.
- the person skilled in the art can easily vary the individual parameters in order to arrive at a favorable embodiment. For safety reasons, one will always want to limit the pressure in the hose. In order to achieve the desired gas flow of up to 50 l / min, with a desired relative humidification of more than 90%, the person skilled in the art will select materials and spacings such that a pressure of ⁇ 50 mm Hg, preferably ⁇ 20 mm Hg, is sufficient.
- the heating wire is wound in the form of a helix over the entire length of the helix with a cotton fabric.
- the water absorption capacity of the porous material is naturally dependent on the particular material. For a normal operation about 200 liters of gas are consumed. To moisten this to approximately 100% relative humidity, ⁇ 10 ml of fluid is needed. It is beneficial if the amount of
- moistening material used can absorb this amount of liquid.
- the hose can provide an optional supply line, which allows the further introduction of water. It will be understood by those skilled in the art that both the water given prior to surgery and, if necessary, during surgery must be sterile.
- the heating element can also be designed so that a change in resistance of the heating element with the heating occurs. By measuring the resistance, the temperature of the heating element can be determined in this case. As a result, the introduction of an additional temperature probe can possibly be avoided.
- the hose according to the invention has the advantage that except for the
- connections are needed so that the hose can be made in one piece.
- the tube can be made cheaper than the solutions mentioned in the prior art.
- the tube can be made of the usual, used in the medical field
- the insufflation tube contains in its interior a further tube through which the insufflation gas is introduced into the insufflation tube.
- This inner tube is gas permeable, so that the gas passage is ensured. This can be done, for example, by the tube containing a multiplicity of openings on its lateral surface, so that the insufflation gas can flow out in the radial direction.
- a so-called braided hose can be used, which are available in various embodiments.
- Hose are the above, preferably silicone, TPU, PUR or PVC, whereby a wire mesh would be conceivable.
- the inner tube is sheathed with the radial outlet openings with the wetting material and the heating element. This can for example be done so that the tube is first covered with a coiled nickel chrome wire and then the moistening material in turn surrounds the heating element.
- first of all a layer of moistening material can serve as a jacket of the inner tube. Around this humidifying material around then the heating element can be wrapped helically.
- this humidifying material around then the heating element can be wrapped helically.
- Embodiment form a second layer moistening material another coat. All of these embodiments have in common that over the entire length of the inner tube, the insufflation gas flows out, especially in the radial direction and this is both heated, as well as moistened. Because of the better
- Moisture absorption of a warmer gas is to be preferred, that first the heating, then the humidification takes place.
- Example 1 A coiled heating element is positioned over a distance of 90 cm in a hose consisting of PVC, which has a length of 3 m.
- Heating element is made of nickel chrome.
- the heating element is powered by an electrical supply and discharge with electricity. It is achieved by means of a voltage of 24 V electrical heating cable of ⁇ 30 watts.
- the heating element is wrapped with sterile gauze bandage as the wetting material so that the heating element has substantially all of the immediate contact with the wetting material. These are the following material cotton 68%, polyamide 24%, elastane 8%.
- a temperature probe is attached to the outlet of the hose (see Figure 1). Before starting the laparoscopy, moisten the porous material with ⁇ 10 ml of sterile water. The supply of water via the additional access / on the patient side end of the hose. The hose will be at his
- Existing temperature probe ensures that the gas temperature on the output side is not higher than 37 ° C.
- a gas flow of up to 50l / min can be delivered to the patient via the tube, which, when using instruments,
- Veresskanüle can fall significantly.
- the laparoscopic procedure using the tube according to the invention can be up to 60 min. Take 10 ml of water through the supply line after 200 liters of gas each time.

- the sheathed hose obtained in this way is inserted into a PVC hose of 3 m length (diameter 10 mm).
- the heating element is supplied via an electrical supply and discharge with electricity. In this case, an electrical heating power of about 50 watts is achieved by means of a voltage of 24 volts.
- the moistening material mentioned above contains not only cotton but also polyamide and elastane (see Example 1). Furthermore, a temperature probe is attached to the outlet of the hose.
- the gas is supplied exclusively via the inner tube.
- FIG. 2 a shows such a hose, which has a multiplicity of openings on the lateral surface.
- the gas supply (1) is shown in the picture on the left.
- FIG. 2b shows the helical sheathing of the hose with the heating wire (3).
- FIG. 2c shows the further casing with the moistening material (4).
