Definitions

• This invention refers to the construction of an extractor of thermoplastic bodies stuck in body cavities, in most cases in the lower respiratory systems in both humans and animals.
• Examples of the former include, an endoscope according to file AU 1998/78557, which consists of an inner and outer tube and, several types of end-piece such as a loop or a bag designed for collection of extracted pieces.
• the disadvantage of this tool is the necessity to disrupt body tissue integrity and this means it is not possible to use it per vias naturales and it is not usable for intervention in the lower respiratory system.
• the integrity of body tissues is also disrupted using the tool described in file WO 94/12110.
• This uses an end-piece composed of an electrically heated element which melts the foreign body.
• a second disadvantage to this method is that it uses no endoscopic technique and hence it is only possible to observe and control the process of medical intervention through the open surgical wound.
• a tool is constructed of a cylindrical tube in whose walls are installed observation and illuminative optics and, guiding wires. Inside the tube a perforation element is fitted and this consists of an extensible mechanical endoscopic tool which has to disrupt the integrity of body tissues during medical intervention, for example by perforation of the abdominal wall (enterocoele).
• This tool is not an extractor and the observation optics are not placed in the middle of the inner tube.
• the tip of the endoscope whose optical head lies on the distal free end of the inner tube allowing for visual guidance is placed in the visual field of the optical head and connected to an incoming cable which is brought outside the outer tube and through to the holder equipped with a switch controlling a heat energy source.
• Fig.1 shows the side view of extractor including endoscope, endoscope optics and light supply
• fig. 2 is the front view of extractor from the side of the end-piece of the working implement.
• the extractor is composed of an outer tube 1 , constructed in the shape of a hollow bilaterally open cylinder made of solid or flexible material, and into which is slid a hollow inner tube 2, also made from solid or flexible material fixed to holder 3.
• a standard endoscope 4 whose optical head 41 is brought out on the distal free end of the inner tube 2 and on the proximal end optically connected with eye-piece 42 equipped with light supply 43.
• working implement 5 which is composed of end-piece 51 , for example heating element, placed in visual field of optical head and attached to incoming cable 52.
• Incoming cable 52 is brought outside outer tube 1 and through holder 3 fitted with switch 31 attached to source 53 of heat energy, controlling heating of the end-piece 51.
• the extractor is pushed in per vias naturales and by the help of optical head 41 of endoscope 4, the position of the body is located and the right place for applying the end-piece 51 of the working implement 5 is determined .
• the tip is heated. This proceeds under the visual control of the physician while he/she gently pushes the tip into the body, sealing the end-piece 51 to the body.
• switch 31 turns off the warming-up of the end-piece 51 which starts to cool down, while the melted body fastens itself to working implement 5 and can be safely extracted from the body cavity under endoscopic control.
• the body is removed from end-piece 51 by heating the working implement 5 once again and, after cleaning and standard sterilization, the extractor is ready to be used again.
• the working implement 5 can be provided for example with a unit for temperature regulation of the end-piece 51 or with an arrangement for its temperature measurement.
• the shape of the end-piece 51 can vary depending on the size and weight of the foreign thermoplastic bodies to be extracted. Further, the shape and design of the endoscope 4 or holder 3 and attachment to light supply 43 or source 53 of heat energy can be changed without influencing the instrument ' s functionality
• This invention has applicability in the manufacture of endoscopic instruments and in medicine, namely for the extraction of thermoplastic bodies stuck in the body cavities per vias naturales when it is impossible to grab them using other implements.
