Abstract
The utility model relates to a can change most advanced directive medical catheter, it is including the main lumen that is used for placing the pjncture needle, first subsidiary lumen and second subsidiary lumen, the bottom of first subsidiary lumen and second subsidiary lumen communicates with the both sides of being responsible for the chamber respectively, and be equipped with the pull wire in first subsidiary lumen and the second subsidiary lumen respectively, the one end of pull wire passes main lumen to the front end of being responsible for the chamber in first subsidiary lumen or the second subsidiary lumen, the other end is stretched out from the top of first subsidiary lumen or second subsidiary lumen respectively, and stretch out the end and be connected with the traction ring. The utility model discloses can change pointed end directive medical catheter's simple structure is with low costs, easily realizes the volume production, and solution that moreover can be fine is in clinical not to put the pipe in place, puts the problem of the unable selection direction of pipe, and the success rate of pipe is put in great improvement.
Description
Technical Field
The utility model relates to a medical catheter, in particular to a medical catheter capable of changing the pointing direction of a tip, which is used for percutaneous puncture in medical treatment.
Background
There are many catheters available on the market for percutaneous puncture, such as drainage catheters for ascites, abscess, biliary drainage, etc., percutaneous dilatation catheters, etc. The catheters are all placed under the guidance of a guide wire during puncture, percutaneous dilation catheters (dilators) can only dilate along a straight line and cannot turn in a certain cavity, for example, percutaneous puncture biliary tract drainage catheters are placed, a pipeline can only move forwards along a main pipeline during catheterization, the pipeline cannot move forwards and select the moving direction when bifurcations and sharp bends occur, and thus the catheterization cannot reach a preset position frequently to cause drainage and therapeutic effect, catheterization failure can be caused, and pain and economic loss are caused to patients.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a medical catheter capable of changing the pointing direction of a tip.
Realize the utility model discloses the technical scheme that the purpose was adopted is: including the main lumen that is used for placing the pjncture needle, first subsidiary lumen and second subsidiary lumen, the bottom of first subsidiary lumen and second subsidiary lumen communicates with the both sides of being responsible for the chamber respectively, and is equipped with the pull wire in first subsidiary lumen and the second subsidiary lumen respectively, and the one end of pull wire passes main lumen to the front end of being responsible for the chamber in first subsidiary lumen or the second subsidiary lumen, and the other end stretches out from the top of first subsidiary lumen or second subsidiary lumen respectively, and stretches out the end and be connected with the traction ring.
The utility model discloses can change pointed end directive medical catheter's simple structure is with low costs, easily realizes the volume production, and solution that moreover can be fine is in clinical not to put the pipe in place, puts the problem of the unable selection direction of pipe, and the success rate of pipe is put in great improvement.
Drawings
Fig. 1 is a schematic structural view of the medical catheter with changeable pointing direction of the tip of the present invention.
In the figure, 1-main lumen (1.1-puncture needle); 2-a first accessory lumen (2.1-a first pull wire, 2.2-a first pull ring); 3-second accessory lumen (2.1-second pull wire, 2.2-second pull ring).
Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments.
As shown in fig. 1, the utility model discloses can change most advanced directive medical catheter, including main lumen 1, first supplementary lumen 2 and second supplementary lumen 3, first supplementary lumen 2 and second are assisted lumen 3 and are located the both sides of main lumen 1 respectively, and the bottom of first supplementary lumen 2 and second supplementary lumen 3 communicates with main lumen 1 respectively, be equipped with first pull wire 2.1 in the first supplementary lumen 2, the one end of first pull wire 2.1 passes main lumen 1 to the front end of being responsible for lumen 1 from first supplementary lumen 2, the other end stretches out from first supplementary lumen 2 top, and stretch out the end and be connected with first pull ring 2.2, be equipped with second pull wire 3.2 in the second supplementary lumen 3, the one end of second pull wire 3.1 passes main lumen 1 to the front end of being responsible for lumen 1 from second supplementary lumen 3, the other end stretches out from second supplementary lumen 3 top, and stretch out the end and be connected with second pull ring 3.2. The first traction wire 2.1 and the second traction wire 3.2 are high-strength polymer wires, and one ends of the first traction wire 2.1 and the second traction wire 3.2, which are positioned at the front end of the main tube cavity 1, are welded together with the front end of the main tube cavity 1 through a fusion head device.
The main cavity 1 in the middle is used for placing a puncture needle 1.1 during catheterization, a guide wire is used, and after the puncture needle guide wire is removed after puncture, a functional main cavity for drainage, medicine injection and the like is formed. When the device is used, the front end of the main tube cavity 1 is stressed by pulling the first traction ring 2.1 and the second traction ring 3.2 left and right, so that the direction of the catheter is changed, and the effect of changing the advancing direction of the catheter in the process of placing the catheter is achieved.
Claims (1)
1. A medical catheter with a changeable tip orientation, comprising: including the main lumen that is used for placing the pjncture needle, first subsidiary lumen and second subsidiary lumen, the bottom of first subsidiary lumen and second subsidiary lumen communicates with the both sides of being responsible for the chamber respectively, and is equipped with the pull wire in first subsidiary lumen and the second subsidiary lumen respectively, and the one end of pull wire passes main lumen to the front end of being responsible for the chamber in first subsidiary lumen or the second subsidiary lumen, and the other end stretches out from the top of first subsidiary lumen or second subsidiary lumen respectively, and stretches out the end and be connected with the traction ring.
