Definitions

  • the invention relates to a device for separating a biological structure, in particular human tissue, and to methods for using such a device.
  • Such a device consists of devices of a water jet cutting system and is used for minimally invasive interventions in human and veterinary medicine.
  • Water jet cutting systems are known and mainly consist of a pressure medium circuit with a pressure generator and corresponding control and regulating devices and a separation medium circuit with a flexible receptacle for the separation medium and one or more handpieces.
  • a desired pressure is generated in the pressure medium circuit which acts directly on the flexible receptacle.
  • the separation medium is displaced from the receptacle and transported via lines to the handpiece, where it exits under pressure.
  • This emerging water jet separates the biological structure in a known manner.
  • Such a system has become known in DE P 42 00 976 of the applicant.
  • This system has a piston-cylinder unit, the piston of which is loaded by the regulated pressure medium and whose movement can be reversed via a directional valve.
  • the cylinder space receives the flexible receptacle for the separation medium.
  • This receptacle is designed as a cartridge and has a positive connection to the cylinder space over the entire stroke of the piston-cylinder unit.
  • This system is characterized in particular by the fact that the pressure in the pressure medium circuit can be adjusted sensitively and continuously and can be transferred to the separation medium in an extremely precise and reproducible manner.
  • the result of this is that the emerging separating medium flow always has a preferred laminar flow, even after emerging from the nozzle of the handpiece, and forms a sharp-edged water jet. A number of significant advantages in use are associated with this sharpness.
  • the object is to design a generic device and to design the methods of its use in such a way that minimally invasive and orthopedic interventions are also possible with it. This object is achieved by the characterizing features of claims 1 and 8.
  • the device combines the advantages of water jet cutting with those of endoscopy and all other known minimally invasive methods.
  • the highly flexible endo-capillary can be inserted through a very small body opening and can be positioned and controlled very precisely in the body, preferably with the aid of endoscopy.
  • a water-jet cutting system which consists of a pressure medium circuit and a separation medium circuit and which has a piston-cylinder unit, the piston of which is loaded by the pressure medium and its cylinder space accommodates a flexible receptacle for the separation medium.
  • the receptacle is designed as a cartridge and has a positive connection with the cylinder space over the entire stroke.
  • This water-jet cutting system in an exemplary manner forms a sharp-edged separating jet which is free from cavitation and turbulence and is therefore excellently suitable for minimally invasive interventions.
  • the separation medium can be introduced into the endo-capillary in a temperature-controlled manner.
  • all known advantages of thermal tissue influencing can be used.
  • a laser can be coupled into the separation medium, so that the endo-capillary can also be used as an optical fluid transmission system.
  • the laser beam guided in the separation medium is preferably used for the crushing of kidney stones.
  • the device can interact with a further pressure generator system which generates pressure spikes and induces them in the separation medium.
  • the device can also be used specifically for minimally invasive interventions for local anesthesia.
  • a nozzle capillary is provided for orthopedic interventions. This allows the cement between the bone and the implant to be removed during joint revisions on implants that have been used with bone cement.
  • the nozzle capillary is particularly suitable for the patient-friendly removal of cement-free implants from the bone. The device is explained in more detail below using an exemplary embodiment.
  • Fig.l a schematic representation of the device.
  • the device works together with a water jet cutting system, which mainly consists of a printer generator device 1 for the separation medium.
  • the pressure generating device 1 can generate the pressure directly in the separation medium or indirectly via a second pressure medium circuit.
  • the pressure of the pressure medium is transferred via a device, for example a piston-cylinder unit, to a flexible receiving container for the separation medium.
  • a line 2 leads from the pressure generating device to an adapter 3 and from there a highly flexible endo-capillary 4 preferably to an endoscope 5.
  • the endoscope 5 is known to consist of a handpiece 6 with a control device 7 and a flexible working tube 8 End of the flexible working tube 8 can be freely positioned using the control device 7.
  • the end capillary 4 is inserted into a working channel 9 of the working tube 8 and protrudes slightly from the working tube 8.
  • the endo capillary 5 has a nozzle 10.
  • the water jet cutting system also has a Adapter 3 leading line 11, in which a heater 12 is integrated.
  • the waterjet cutting installation furthermore has a line 13 leading to the adapter 3 with a pressure pulse generator device 14 and a further line 15 with a laser beam generating device 16.
  • the device additionally has a cartridge filled with anesthetic, which is inserted into the pressure generating device 1 and is connected to an anesthetic capillary 17 by means of the line 2 via the adapter 3. It is also connected via the adapter 3 to a nozzle capillary 18 for optional use in orthopedics.

Abstract

Les dispositifs de découpe par jet d'eau connus ont un usage limité aux endroits accessibles à la main et à la pièce à main de l'opérateur. Pour des opérations très peu invasives et orthopédiques, le tube capillaire se présente sous forme de tube endocapillaire (4) et est associé de préférence à un endoscope (5). L'invention concerne également l'utilisation de ce dispositif dans des opérations très peu invasives et orthopédiques.
