Beneficial effect of the present invention is: the lateral wall of guidewire body of the present invention is provided with polytetrafluoroethylene floor, has lower coefficient of friction, reduces the resistance that seal wire delivery process produces; And scale and scale value are set on polytetrafluoroethylene floor, the clear and definite paracentesis depth of energy and position; Structure is simple, economical and practical, remains that stones in intrahepatic bile duct, renal pelvis operating walk way are open, reduces the complication such as renal pelvis, bile duct mucosa injury, shorten operating time, improve puncture success rate.
Seal wire tool of the present invention has the following advantages: 1, have scale marker, specifies paracentesis depth and position; 2, operating walk way is set up in guiding; 3, fast and easy, saves operating time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Reference numeral is: 1-guidewire body, 2-polytetrafluoroethylene floor, 3-scale, 31-long scale, 32-short scale, 4-scale value.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with embodiment and accompanying drawing 1, the present invention is further illustrated, and the content that embodiment is mentioned not is limitation of the invention.
See Fig. 1, a kind of safety scale guides seal wire, comprise flexible guidewire body 1, the lateral wall of described guidewire body 1 is provided with polytetrafluoroethylene floor 2, polytetrafluoroethylene floor 2 is provided with scale 3 and scale value 4, scale 3 comprises long scale 31 and short scale 32, four short scales 32 are provided with between adjacent two long scales 31, distance between adjacent two long scales 31 is 0.5cm, distance between adjacent two short scales 32 is 0.1cm, scale value 4 is arranged at the side of long scale 31, and from the front end of guidewire body 1, a scale value 4 is set every two long scales 31.
Polytetrafluoroethylene floor 2 makes the outer wall of guidewire body 1 of the present invention have lower coefficient of friction, reduces the resistance that guidewire body 1 delivery process produces; And scale 3 and scale value 4 are set on the surface of polytetrafluoroethylene floor 2, the clear and definite paracentesis depth of energy and position; Structure is simple, economical and practical, remains that stones in intrahepatic bile duct, renal pelvis operating walk way are open, reduces the complication such as renal pelvis, bile duct mucosa injury, shorten operating time, improve puncture success rate.
In the present embodiment, the lateral wall of described guidewire body 1 has not in conplane barber-pole stripes.Arranging of barber-pole stripes can reduce resistance, is easy to manipulation simultaneously.
In the present embodiment, the length of described guidewire body 1 is 1-5m.For making the present invention reach best result of use, the length of described guidewire body 1 is 3m.
