Description
Technical field
The utility model relates to the field of medical instrument technology, espespecially a kind of temporary cardiac pacing conductor structure.
Background technique
After cardiac surgery usually needs indwelling temporary cardiac pacing conducting wire, passes through temporary cardiac pacing conducting wire when arrhythmia cordis occurs after surgery
It connect and is treated with temporary pacemaker, temporary cardiac pacing conducting wire is pulled out generally before discharge.
Existing temporary cardiac pacing conductor structure schematic diagram as shown in Figure 1, including suture syringe needle 1 ' and with suture syringe needle 1 ' one
The Pacing lead 2 ' of connection is held, 2 ' outside of Pacing lead is provided with conductor casing 3 ', and the two is fitted close.
Existing temporary cardiac pacing conducting wire has two when extracting from human body:
(1) it directly pulls out, it is possible to make human heart bleeding due to trauma；
(2) cut Pacing lead 2 ', stay it in intradermal, but the stump of postoperative Pacing lead 2 ' can shouting pain skin, be
Patient leaves long-term pain.
Therefore, it is simple how to design a kind of structure, human body cardiac muscle will not be damaged when pulling out and causes bleeding, does not have stump thorn
Pain skin, the temporary cardiac pacing conductor structure of no tingling sensation are the projects that the present inventor concentrates on studies.
Utility model content
In order to overcome the above technical problems, the purpose of this utility model is to provide a kind of temporary cardiac pacing conductor structure,
Structure design is simple, and it is convenient to place, identical as common Pacing lead, when pulling out will not injury of myocardium cause bleeding, do not have residual
Terminal spine pain skin, no tingling sensation.
To achieve the goals above, the utility model provides a kind of temporary cardiac pacing conductor structure, including suture syringe needle,
The suture syringe needle is connect with indwelling conducting wire, and the indwelling conducting wire other end is connected and fixed with connected ball, the connected ball it is another
One end and one end of conducting wire are slidably connected, and the outer surface on the conducting wire close to the other end is closely provided with the first conductor casing.
Preferably, the outer surface of the indwelling conducting wire is provided with multiple hangnails.
Preferably, further include the second conductor casing, second conductor casing be placed on outside conducting wire be located at connected ball with
Part between first conductor casing, the internal diameter of second conductor casing is greater than the diameter of the conducting wire, and is less than the company
The diameter received.
Preferably, outer diameter of the internal diameter of second conductor casing less than the first conductor casing.
Preferably, it is linked together between the connected ball and the conducting wire using inserting mode.
After adopting the above scheme, the utility model temporary cardiac pacing conductor structure by with conducting wire be not close contact second
Interaction between conductor casing and connected ball, the power for extracting conducting wire do not act on heart, and avoiding heart may
Therefore bleeding caused by；And only remaining surface has barbed indwelling conducting wire to this conductor structure after pulling out and connected ball exists
In vivo, will not shouting pain skin, patient do not have tingling sensation.It is convenient that the Pacing lead structure is placed, identical as common Pacing lead.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing temporary cardiac pacing conducting wire；
Fig. 2 is the structural schematic diagram of the utility model temporary cardiac pacing conductor structure.
Specific embodiment
Below with reference to the accompanying drawings illustrate the embodiments of the present invention.In an attached drawing of the utility model or a kind of implementation
Elements and features described in mode can be with elements and features shown in one or more other drawings or embodiments
It combines.It should be noted that for purposes of clarity, attached drawing and it is omitted that unrelated with the utility model, this field is general in illustrating
The expression and description of component known to logical technical staff or processing.
The utility model temporary cardiac pacing conductor structure is described further with reference to the accompanying drawing.
As shown in Fig. 2, the utility model temporary cardiac pacing conductor structure includes suture syringe needle 1, suture syringe needle 1 and indwelling conducting wire
2 connections, the outer surface of indwelling conducting wire 2 is provided with multiple hangnails 3.The other end of indwelling conducting wire 2 is connected and fixed with connected ball 4, even
Receive 4 one end of the other end and conducting wire 5 is slidably connected, and is connected between the present embodiment connected ball 4 and conducting wire 5 using inserting mode
It connects.Outer surface on conducting wire 5 close to the other end (suspension end) is closely provided with the first conductor casing 6.
It further include the second conductor casing 7, the second conductor casing 7, which is placed on outside conducting wire 5, is located at connected ball 4 and the first conducting wire
Part between shell 6, the internal diameter of the second conductor casing 7 is greater than the diameter of conducting wire 5, and is less than the diameter of connected ball 4.Second leads
Outer diameter of the internal diameter of line shell 7 less than the first conductor casing 6.
When Lead extraction 5, the second conductor casing 7 is first fixed, or gently inwardly firmly heads on the second conductor casing 7
Connected ball 4 pulls out the first conductor casing 6 outward.The active force formed between the second conductor casing 7 and connected ball 4, promotes conducting wire
5 separate with the sliding of connected ball 4.When conducting wire 5 is separated with connected ball 4, the sense that falls through, and conducting wire 5 and the second conductor casing 7 hair are had
Raw relative motion.Then the second conductor casing 7 is pulled out outward, is extracted together with conducting wire 5 and the first conductor casing 6, only lower tape
The indwelling conducting wire 2 of hangnail 3 and connected ball 4 will not have damage surrounding tissue in internal.5 whole process of conducting wire is extracted without cardiac muscular tissue
Stress not will cause myocardial damage bleeding.
