Abstract
The utility model discloses an interventional catheter for a minimally invasive surgery. The outer surface of the catheter is provided with depth marks, wherein the depth marks are calibration loops which are coated on the surface of the catheter and consist of thick loops (1) and thin loops (2); and the thin loops (2) are arranged among the thick loops (1). By the interventional catheter, the insertion depth of the catheter can be controlled conventionally, quickly and accurately.
Description
Technical field
This utility model relates to a kind of interventional medical utensil, particularly a kind of Minimally Invasive Surgery interposing catheter.
Background technology
In the clinical intervention property Minimally Invasive Surgery, the insertion depth of interposing catheter is very important, and dark mistake is shallow excessively all can influence operative treatment, but the prior art conduit generally only has a degree of depth to indicate, and the doctor will the dependence experience grasp tube insertion depth, and error is big.For overcoming this problem; There are the invention personnel to propose catheter surface is provided with the technology that a plurality of scales indicate; So that can accurately hold tube insertion depth, but still exist not enough: the conduit scale indicates evenly and the size shape indifference, and surgical staff is seen easily and obscured; Need carefully distinguish, influence intubate speed.
Summary of the invention
The purpose of this utility model is not enough to prior art, and the Minimally Invasive Surgery interposing catheter of the convenient accurate grasp catheter depth of a kind of ability is provided.
This utility model is achieved in that a kind of Minimally Invasive Surgery interposing catheter, and the outer surface of conduit is provided with the degree of depth and indicates, and this degree of depth is denoted as the calibration loop that is coated in catheter surface, and calibration loop is made up of thick ring and thin ring, and thin ring is arranged between the thick ring.
As the further improvement of this utility model, 3～6 thin rings evenly are set between the adjacent thick ring, the spacing between the adjacent thin ring is 4～10mm.
This utility model not only is provided with a plurality of scales and indicates, and scale is divided into thick ring, carefully encircles two kinds, and thin ring spacing is little, is convenient to accurately grasp depth distance, and thick ring spacing is big, is convenient to distinguish fast the overall depth of insertion, and simple operation is accurate.
Description of drawings
Accompanying drawing is the structural representation of this utility model.
Among the figure, 1, thick ring, 2, thin ring.
The specific embodiment
Describe below in conjunction with the specific embodiment of accompanying drawing this utility model.Catheter outer surface applies the calibration loop of a plurality of marked effects, and calibration loop is made up of thick ring 1 and thin ring 2, carefully encircles 2 spacings and is arranged on uniformly between the thick ring 1.Calibration loop can adopt does not influence the coating processes of conduit pliability processing and fabricating.
Claims (2)
1. Minimally Invasive Surgery interposing catheter, the outer surface of conduit are provided with the degree of depth and indicate, and it is characterized in that: this degree of depth is denoted as the calibration loop that is coated in catheter surface, and calibration loop is made up of thick ring (1) and thin ring (2), carefully encircle (2) and are arranged between the thick ring (1).
2. Minimally Invasive Surgery interposing catheter according to claim 1 is characterized in that: 3～6 thin rings (2) evenly are set between the adjacent thick ring (1), and the spacing between the adjacent thin ring (2) is 4～10mm.
