Abstract
The utility model discloses in a kind of arteriovenous internal fistula formation with the blunt nosed looper of band scale, comprise needle tubing and syringe needle, described syringe needle is looper, and described looper is made up of at an angle near section and section far away, and described looper needle point is blunt nosed, described far away section with scale.The simultaneously veiny fluidity expansion of tool of this utility model and to original position outside diameter measuring function after original position outside diameter measuring, venous anastomosis before outside diameter measuring, arterial anastomosis after the expansion of vein fluidity.The looper of angulation can be easily by the far away section of blood vessel below of stretching into deep, art district, because volume is fine, do not increase the secondary damage of adjacent structure or involve risk, blood vessel keeps original position, full state, measures accurately.
Description
Technical field
This utility model belongs to medical instruments field, provide especially in a kind of arteriovenous internal fistula formation with the blunt nosed looper of band scale, for arteriovenous internal fistula formation, can carry out the fluidity expansion before vein end coincide, original position outside diameter measuring after original position outside diameter measuring, venous anastomosis before the rear outside diameter measuring of vein fluidity expansion, arterial anastomosis.
Background technology
Internal arteriovenous fistula is the first-selected vascular access of hemodialysis patients.Forearm arteriovenous urethroptasty is that dialysis patient is set up the first-selected art formula of vascular access, by cephalic vein and radial artery or basilic vein and the capable end end of ulnar artery, distolateral or side to side anastomosis.As venous anastomosis is last, carry out fluidity expansion or apparatus expansion, can improve the rear internal fistula patency rate that coincide.Expansion posterior vein diameter, when particularly full vein diameter be greater than 4mm and coincide after patency rate higher, be less than 4mm postoperative patency rate decline.Identical rear patency rate is higher as being greater than 3mm for original position artery diameter, is less than postoperative patency rate decline of 3mm.The posterior vein diameter that coincide is greater than 3mm, and identical rear patency rate is higher, is less than postoperative patency rate decline of 3mm.After anastomotic stoma original position is full, identical rear patency rate is higher as being greater than 4mm for diameter, is less than postoperative patency rate decline of 4mm.
Existing operation needle tubing only can be expanded vein, and still lacks at present special survey tool in art, mainly relies on patient's bore hole assessment, and steel ruler is wrapped into high-temperature sterilization operation bag, in art, blood vessel is lifted and measures with steel ruler.But it is high to only depend on open hole survey to require patient's experience, and poor accuracy, cannot accurate quantification, more cannot record rear statistics or comparison.As steel ruler wrapped in operation bag, not only increase disinfection cost, increase pollution risk; In addition, because artery position is darker, steel ruler size is larger, is difficult to stretch into deep, art district and measures, and as carried on blood vessel to superficial part, not only increases damage risk, and on blood vessel charge less after carrying be full of, measure inaccurate.
Utility model content
The purpose of this utility model is to provide in a kind of arteriovenous internal fistula formation uses the blunt nosed looper of band scale, can effectively address the above problem.
The technical solution of the utility model is: in arteriovenous internal fistula formation, use the blunt nosed looper of band scale, comprise needle tubing 1 and syringe needle 2, described syringe needle 2 is looper, and described looper is made up of at an angle near section of 2a and section 2b far away, described looper needle point is blunt nosed 2c, and described far away section of 2b is with scale 2d; Looper can carry out the fluidity expansion before vein end coincide, original position outside diameter measuring after outside diameter measuring, the front original position outside diameter measuring of arterial anastomosis, venous anastomosis after the expansion of vein fluidity, blunt nosed 2c can prevent from scratching arteriovenous in operation, and the looper of angulation can stretch into far away section of 2b the blood vessel below in deep, art district easily.
Preferably, described near section of 2a and section 2b far away are hexagonal angle setting; Preferred angle can facilitate operation technique.
Preferably, described far away section of 2b length is 3cm, starts to count scale from needle point, every 1cm labelling horizontal line, the long horizontal line of every 0.5cm labeling moiety, every 0.1cm labelling strigula; Scale mark can be convenient for measuring counting.
Preferably, described near section of 2a length is 4-5cm; Preferred nearly section 2a length facilitates operation technique, laborsaving.
The utlity model has following useful effect:
The simultaneously veiny fluidity expansion of tool of this utility model and to original position outside diameter measuring function after original position outside diameter measuring, venous anastomosis before outside diameter measuring, arterial anastomosis after the expansion of vein fluidity.The looper of angulation can be easily by the far away section of blood vessel below of stretching into deep, art district, because volume is fine, do not increase the secondary damage of adjacent structure or involve risk, blood vessel keeps original position, full state, measures accurately.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in detail.
As shown in Figure 1, 2, in arteriovenous internal fistula formation, with the blunt nosed looper of band scale, comprise needle tubing 1 and syringe needle 2, syringe needle 2 is looper, looper is hexagonal angle by near section of 2a and section 2b far away and forms, and the looper of angulation can stretch into far away section of 2b the blood vessel below in deep, art district easily, and hexagonal angle can facilitate operation technique.
Looper needle point is blunt nosed 2c, and blunt nosed 2c can prevent from scratching arteriovenous in operation.
Section 2b far away is with scale 2d, and looper can carry out the identical front fluidity expansion of vein end, original position outside diameter measuring after outside diameter measuring, the front original position outside diameter measuring of arterial anastomosis, venous anastomosis after the expansion of vein fluidity.
Section 2b length far away is 3cm, starts to count scale from needle point, every 1cm labelling horizontal line, and the long horizontal line of every 0.5cm labeling moiety, every 0.1cm labelling strigula, scale mark can be convenient for measuring counting.
Nearly section 2a length is 4-5cm, and nearly section 2a length facilitates operation technique, laborsaving.
The simultaneously veiny fluidity expansion of tool of this utility model and to original position outside diameter measuring function after original position outside diameter measuring, venous anastomosis before outside diameter measuring, arterial anastomosis after the expansion of vein fluidity.The looper of angulation can be easily by the far away section of blood vessel below of stretching into deep, art district, because volume is fine, do not increase the secondary damage of adjacent structure or involve risk, blood vessel keeps original position, full state, measures accurately.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to this utility model spirit change or modify, within all should being encompassed in protection domain of the present utility model.
