Description
Technical field
The present invention relates to a kind of medical supplies, relate in particular to a kind of trocar.
Background technology
After the pin that hemodialysis is at present used punctures successfully, when the puncture side limbs change a little, easy injured blood vessel of puncture needle and tissue, sometimes need limbs to be in a fixed position, but make patient feel tired easily, and each dialysis all needs to puncture again, bring misery to patient, result of use is poor.
Summary of the invention
The purpose of this invention is to provide the good trocar of a kind of result of use.
To achieve these goals, the technical scheme that the present invention takes is: a kind of trocar, comprise the pin heart, pin heart outside is with needle tubing, the pin heart is corresponding with needle tubing, it is characterized in that, the right-hand member of the described pin heart is fixedly connected with inner sleeve, the pin heart communicates with inner sleeve, inner sleeve is with trocar sheath outward, and trocar sheath is connected with the right-hand member of needle tubing, and trocar sheath and needle tubing are an integral body, trocar sheath communicates with needle tubing, the outer surface design of the right-hand member of needle tubing has the pin wing, and the outside of trocar sheath is with clip, and the right part of trocar sheath has nut, long and the trocar sheath of inner sleeve, needle tubing is a flexible pipe.
The right output port place design of inner sleeve has dust cap.
Advantageous effect of the present invention is: the right-hand member of the pin heart among the present invention is fixedly connected with inner sleeve, inner sleeve is with trocar sheath outward, trocar sheath is connected with the right-hand member of needle tubing, the outer surface design of the right-hand member of needle tubing has the pin wing, the outside of trocar sheath is with clip, the right part of trocar sheath has nut, the long and trocar sheath of inner sleeve, and needle tubing is a flexible pipe, so use the present invention can puncture conveniently, after puncturing successfully, avoid injured blood vessel and tissue, make limbs can be in functional position, avoid the fatigue of limbs, and can be connected with extracorporeal circulation pipeline arterial end syndeton rapidly, can avoid that the trocar is terminal to be polluted, prevent that the trocar from deviating from outside the blood vessel, reduce trouble, be convenient to operation, result of use is good
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further:
A kind of trocar, as shown in Figure 1, comprise the pin heart 7, the pin heart 7 outsides are with needle tubing 6, the pin heart 7 is corresponding with needle tubing 6, the right-hand member of the pin heart 7 is fixedly connected with inner sleeve 4, and the pin heart 7 communicates with inner sleeve 4, the inner sleeve 4 outer trocar sheaths 5 that are with, trocar sheath 5 is connected with the right-hand member of needle tubing 6, trocar sheath 5 is an integral body with needle tubing 6, and trocar sheath 5 communicates with needle tubing 6, and the outer surface design of the right-hand member of needle tubing 6 has the pin wing 1, the outside of trocar sheath 5 is with clip 2, the right part of trocar sheath 5 has nut 3, inner sleeve 4 long and trocar sheaths 5, and needle tubing 6 is a flexible pipe; In the present embodiment, the design of the right output port place of inner sleeve 4 has dust cap 8.
Use when of the present invention,, close clip earlier and puncture, open clip then at the end of inner sleeve mounting of syringe, if blood back is arranged, illustrate and puncture successfully fixed needle, then the pin heart is extracted out, trocar sheath 5 is connected with extracorporeal circulation pipeline arterial end syndeton by nut, dialyse.
The present invention can reuse, and when finishing using, uses the heparin saline tube sealing, closes switch, and end directly is retained in puncture position with the medicated cap sealing, directly uses next time, reduces dialysis person's misery, reduces trouble, and is convenient to operation,
The present invention also is applicable to the critical patient simultaneously.
