Abstract
The utility model discloses a drainage tube puncture device comprising at least one puncture needle. The puncture needle is composed of a needle tip, a needle body and a needle end. The utility model is characterized in that: a fixed structure matching with the end of the drainage tube is arranged at the needle end. In the clinical operation, different layers of tissue and the skin are pierced by the needle tip of the puncture needle on the utility model. The drainage tube can be taken out directly after the puncture needle pierces out. The shape and size of the perforation match with the drainage tube so that the problems of the effusion of the drainage tube and the obstructed drainage caused by the narrow shape change for the pressure on the drainage tube lumen are solved. Besides, less tissue injury is caused.
Description
Technical field
This utility model relates to a kind of device that is used to import drainage tube in wound drainage, is specifically related to a kind of drainage tube sting device.
Background technology
In the clinical surgery operation process, often need insert drain at the drain position, for example various drainage tubes, drainage tube material commonly used comprises silica gel, latex, PVC plastics etc.Usually, when placing drainage tube, need to wear out each layer tissue from inside to outside to subcutaneous with vascular forceps earlier, on skin, cut out outlet again, drainage tube is drawn with scalpel.Drainage tube one end is positioned at the drain position, and the other end is free on outside the skin.In the above-mentioned drainage tube laying method,, cause drain to ooze out easily outward, drainage tube chamber is narrowed down and cause inadequate drainage by drainage tube because the tissue tunnel that the outlet place that cuts out of scalpel forms and the shape and the size of drainage tube do not match; Simultaneously, owing to must sew up skin and use the silk thread ligation with sewing needle at drainage tube outlet place, airtight and fixing with skin on every side drainage tube, operation technique be more loaded down with trivial details.
Summary of the invention
This utility model purpose provides a kind ofly can place drainage tube easily, and can guarantee the unimpeded drainage tube sting device of drainage tube.
For achieving the above object, the technical solution adopted in the utility model is: a kind of drainage tube sting device, comprise a puncture needle at least, and described puncture needle is made of needle point, needle body and backshank, and described backshank is provided with the fixed structure that cooperates with the drainage tube end.
During use, the drainage tube end is enclosed within on the fixed structure of backshank, directly wears out each layer tissue and skin, drainage tube is drawn get final product with puncture needle.Above, the shape of puncture needle can change according to the operation needs, can be staight needle, also can be the arc pin, and needle point can be conical, also can be polygonal pyramid shape (for example triangular pyramid).
In the technique scheme, described fixed structure can be various engagement connection structures or screw connection structure, optimized technical scheme is, described fixed structure is the snap-in structure that at least three joint agnails constitute, the maximum gauge place of agnail is greater than the internal diameter of drainage tube, and the minimum diameter place is less than the internal diameter of drainage tube.
Further technical scheme; the excessive drainage tube that causes of resistance comes off from puncture needle when puncturing in order to avoid; protective casing can also be set; described protective casing front end is provided with inside projection; the needle body of described puncture needle is provided with the groove that cooperates with the projection of protective casing, and the connecting portion of drainage tube and puncture needle is in the tube chamber inside of protective casing.
In the technique scheme, described needle body upper groove is suitable to the external diameter of the diameter of needle point section and protective casing, and groove is suitable to the internal diameter of the diameter of backshank section and protective casing.
Because the technique scheme utilization, the advantage that this utility model compared with prior art has is:
1. owing to comprised puncture needle in the sting device of the present utility model, fixed structure by its backshank, drainage tube can be fixed on the puncture needle, thereby, when clinical operation, wear out each layer tissue and skin with the needle point of puncture needle of the present utility model, can directly take drainage tube out of after puncture needle passes, perforation shape, size cooperate with drainage tube;
2. telescopic setting makes resistance mainly be passed on the puncture needle by sleeve pipe, and the connecting portion of drainage tube and puncture needle is stressed less, and difficult drop-off has guaranteed the success rate of performing the operation;
Since drainage tube to draw the tissue tunnel that the back forms identical with drainage tube, be difficult for causing the drainage tube pipe oozes out, drainage tube tube chamber pressurized narrows down problems such as causing inadequate drainage outward, and less to tissue injury.
