Abstract
The utility model discloses a shock-wave guide tube of an in-vivo electro-hydraulic lithotripsy electrode, which is a column with one end being arranged on a discharge end of the in-vivo electro-hydraulic lithotripsy electrode, wherein a stainless steel cover is the external layer thereof; two electrodes including a ring electrode and a core electrode are disposed inside the stainless steel cover; an insulating layer is used both between the stainless steel cover and the ring electrode and between the stainless steel cover and the core electrode for insulation; and an electrode discharge area is disposed on the other end relative to the discharge end of the in-vivo electro-hydraulic lithotripsy electrode. With the utility model, electro-hydraulic lithotripsy shock waves formerly discharged in a semi-spherical manner are changed into straight-line bundle-type shock waves, the shock waves are intensively applied on relatively big calculus surfaces inside a human body biliary tract, strength of the electro-hydraulic lithotripsy shock waves discharged inside the human body biliary tract can be greatly reduced and lithotripsy efficiency is increased by times on the contrary. In this way, traditional minimally invasive operations for treatment of hepatic and biliary calculus diseases become safer and more efficient.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to the shock wave guide pipe of electrohydraulic lithotripsy electrode discharge end in a kind of body, belongs to International Classification of Patents A61: medical science or veterinary, hygiology.
Background technology
China medical and health organization adopts liver, cholelithiasis disease in minimal invasive operation mankind body, the history of existing nearly 20 years.Implementing this type of when operation, often need to be by a superfine therapeutic electrode, by the shock wave energy of electrohydraulic stone crusher release in body, by the biopsy channel of choledochoscope, in human body biliary tract compared with discharging on maximum size surface, thereby reach the object of lithotripsy in treatment.Traditional rubble shock wave is hemispherical and discharges.
Due in human body biliary tract compared with maximum size; conventionally with incarceration, the form in biliary tract occurs; and the limited space in human body biliary tract; the hemispherical electrohydraulic lithotripsy shock wave discharging usually can injure human body biliary tract interior wall tissue; when serious, can cause biliary tract perforation; the hemispherical electrohydraulic lithotripsy shock wave discharging simultaneously; because its shock wave energy of broadcasting to all directions equates; the energy acting in calculus surfaces only accounts for below 25% of its whole energy; therefore calculifragous efficiency is not very good yet, need to take measures to be improved.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of facility that discharges of new electrohydraulic lithotripsy shock wave is provided.
For reaching this object, the technical solution adopted in the utility model is:
A shock wave guide pipe for electrohydraulic lithotripsy electrode in body is that an one end installs the cylinder on electrohydraulic lithotripsy therapeutic electrode discharge end in vivo additional; Its skin is stainless steel outer sleeve; Stainless steel outer sleeve inside comprises two electrodes: annular electrode and core electrode.Between stainless steel outer sleeve and annular electrode, by external insulation layer, insulated, between annular electrode and core electrode, by inner insulating layer, insulated.In the body with respect to described, the other end of electrohydraulic lithotripsy therapeutic electrode discharge end, is provided with electrode discharge region.
Described cylinder external diameter 1.6mm, long 5mm.
Described stainless steel outer sleeve wall thickness 0.2mm.
Described annular electrode is cylindric.
Described core electrode is round wire.
This utility model makes original in the hemispherical electrohydraulic lithotripsy shock wave discharging, in the metallic object newly installing additional, electrohydraulic lithotripsy electrode shock wave guide pipe gathers, under guiding, change into straight line pencil shock wave, straight concentrate act in human body biliary tract compared with maximum size surface, because having, electrohydraulic lithotripsy electrode shock wave guide pipe in the metallic object newly installing additional gathers, the effect of guiding electrohydraulic lithotripsy shock wave, so the electrohydraulic lithotripsy impact intensity of wave of discharging in human body biliary tract can reduce greatly, calculifragous efficiency but increases exponentially, make traditional treatment mankind liver, the Minimally Invasive Surgery of cholelithiasis disease, in safety, reliably, the aspects such as efficiency, there is a very large raising., make its safety and efficiently more.Thereby better assist medical personnel, remove patient's disease and misery.
