Abstract
The utility model discloses a percutaneous renal access expanding suit which comprises a puncture needle with a core, a puncture needle sleeve pipe and a sacculus guide wire. A first scale mark is arranged on the puncture needle sleeve pipe. The inner diameter of the puncture needle sleeve pipe is larger than the outer diameter of the puncture needle with the core. The puncture needle with the core is twice longer or more than twice longer than the puncture needle sleeve pipe. The outer diameter of the sacculus guide wire is smaller than the inner diameter of the puncture needle sleeve pipe. A sacculus is arranged at one end of the sacculus guide wire in a seal and sleeved mode. A tail end seal cap is arranged at the other end of the sacculus guide wire. A water injection hole is formed in the outer wall of the sacculus guide wire, wherein the position of the water injection hole corresponds to the position of the sacculus. A second scale mark is arranged on the sacculus guide wire. The percutaneous renal access expanding suit can ensure that the sacculus guide wire is fixed in a collection system instead of falling out after a successful puncture. Due to the good fixing of the sacculus guide wire, deviation of the expanding direction is avoided. The expanding depth of an expanding device can be accurately controlled. Due to the buffering of the sacculus, mistaken damage caused by insufficient expanding depth or excessive expanding depth is avoided.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of percutaneous kidney passage expansion external member, is applicable to the kidney stone operation.
Background technology
The PCN technology is the topmost Minimally Invasive Surgery mode of current treatment kidney stone.Its prerequisite is to need to set up through the artificial channel of skin to the kidney aggregation system.The mode of setting up at present passage is mainly 3 kinds: 1, Amplatz fascia dilator; 2, rod-pulling type metal dilator; 3, balloon dilatation catheter, the most commonly used is the Amplatz fascia dilator.Its mode all is to insert seal wire by the puncture nook closing member after puncturing successfully.Then fascia dilator is expanded step by step along seal wire, and the peeling sheath is inserted in the most at last.Yet expand after puncturing successfully and unsuccessfully mainly concentrate on two kinds of situations: 1. calculus is little with small cup wall gap, seal wire is inserted shallow, and the kidney that is caused by the patient respiratory activity moves, or certain deviation appears in dimension, easily make seal wire skid off aggregation system, thereby cause the Path Setup failure.2. expand the damage of taking an advanced study into the aggregation system oppose side wall, caused hemorrhage or perforation, increased operation risk and difficulty.
The utility model content
The purpose of this utility model is the problems referred to above that are for the prior art existence, a kind of percutaneous kidney passage expansion external member is provided, seal wire deviates from and expand the mistake of taking an advanced study and damage, success rate and the safety of raising percutaneous kidney Path Setup after can preventing from puncturing successfully.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
A kind of percutaneous kidney passage expansion external member, comprise the belt carcass puncture needle, also comprise puncture needle sleeve pipe and sacculus silk-guiding, be provided with the first reference mark on the belt carcass puncture needle, the internal diameter of puncture needle sleeve pipe is greater than the external diameter of belt carcass puncture needle, the belt carcass needle length is more than or equal to the Puncture needle sleeve length of tube of twice, the sacculus silk-guiding external diameter is less than the Puncture needle sleeve bore, sacculus silk-guiding one end sealing shroud is provided with sacculus, the other end is provided with the tail end sealing cap, position corresponding to sacculus on the sacculus silk-guiding tube wall offers water injection hole, is provided with the second reference mark on the sacculus silk-guiding.
The external diameter of aforesaid belt carcass puncture needle is 1 millimeter, and length is 20 centimetres; The internal diameter of described puncture needle sleeve pipe is 1.5 millimeters, and external diameter is 1.7 millimeters, and length is 10 centimetres; Described sacculus silk-guiding external diameter is 1 millimeter, and length is 40 centimetres; Capacity is 3 milliliters after the inflation, and external diameter is 1 centimetre.
This utility model compared with prior art has the following advantages:
1, ensures that the successful rear gasbag seal wire of puncture can be fixed in the aggregation system not deviate from;
2, because the good of air bag guide wire fixed, dimension can be offset;
3, can accurately control the expansion degree of depth of dilator, the buffering of sacculus can be avoided expanding the degree of depth not or expand the generation of taking an advanced study into the mistake damage in addition.

The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail.
Embodiment 1
Shown in Fig. 1 ~ 5, a kind of percutaneous kidney passage expansion external member, comprise belt carcass puncture needle 1, also comprise puncture needle sleeve pipe 2 and sacculus silk-guiding 4, be provided with the first reference mark 3 on the belt carcass puncture needle 1, the internal diameter of puncture needle sleeve pipe 2 is greater than the external diameter of belt carcass puncture needle 1, belt carcass puncture needle 1 length is more than or equal to puncture needle sleeve pipe 2 length of twice, sacculus silk-guiding 4 external diameters are less than puncture needle sleeve pipe 2 internal diameters, sacculus silk-guiding 4 one end sealing shrouds are provided with sacculus 5, the other end is provided with tail end sealing cap 7, and the position corresponding to sacculus 5 on sacculus silk-guiding 4 tube walls offers water injection hole 6, is provided with the second reference mark on the sacculus silk-guiding 4.
The external diameter of belt carcass puncture needle 1 is 1 millimeter, and length is 20 centimetres; The internal diameter of described puncture needle sleeve pipe 2 is 1.5 millimeters, and external diameter is 1.7 millimeters, and length is 10 centimetres; Described sacculus silk-guiding 4 external diameters are 1 millimeter, and length is 40 centimetres; Capacity was 3 milliliters after sacculus 5 expanded, and external diameter is 1 centimetre.
