Abstract

The utility model relates to a kind of surgical interventional puncture needle, in particular a kind of interventional puncture needle. The utility model provides a kind of interventional puncture needle of simple structure, easy operation, and less repeated puncturing. The interventional puncture needle includes a needle body 1; one end of the needle body is sharp, while the other end is the needle handle 2; the needle handle 2 is integrated with the needle body 1 to be a whole body with the hollow cavity tube 3 of the needle handle; the needle handle 2 is transparent and is provided with the guide mouth 4; the inner wall of the needle handle cavity on the other side of the guide mouth 4 is provided with the heave 5. With the use of the above structure, the transparent needle handle is convenient for observe whether the puncturing is successful or not; the guide mouth and the heave in the place of the guide mouth can prevent sliding when puncturing, and can avoid that the complex operation causes the sleeve end out of the vascular cavity; or if the sleeve goes out of the vascular cavity in the insertion process, the device can avoid the puncturing failure causes suffering to the patients.

Description

Get involved puncture needle

One, technical field: this utility model relates to a kind of intervention puncture surgical needles, especially a kind of intervention puncture needle.

Two, background technology: at present with getting involved puncture needle needle body, needle handle carefully and be plugged on together, needle body sleeve has sleeve pipe, and sleeve pipe can be plugged on by needle body with needle handle, and needle point is longer than sleeve pipe.During operation sleeve pipe and needle body are punctured into the focus blood vessel together, need the assistant to help to extract needle body needle handle and sleeve pipe are pegged graft,, seal wire is imported by needle handle treat again because cannula tip is stayed in the focus blood vessel.Therefore, whole process operation is complicated, and amount of bleeding is big, also makes cannula tip deviate from lumen of vessels in the grafting process easily, perhaps penetrates blood vessel rear wall seal wire and inserts difficulty, causes puncture failure.

Three, summary of the invention: the purpose of this utility model is to provide a kind of puncture simple in structure, easy and simple to handle and seal wire to insert only needs single one-handed performance to get final product.Need not to change hands, need not assistant's help, avoid needle tip to deviate from lumen of vessels, reduce the intervention puncture needle of repeated puncture.Get involved puncture needle and comprise needle body 1, needle body 1 one ends are sharp-pointed, and the other end is a needle handle 2, and needle handle 2 is connected to one with needle body 1 and is provided with the needle handle lumen 3 of hollow, and needle handle 2 is for transparent and be provided with introducing port 4, and the opposite side needle handle cavity wall of introducing port 4 is provided with projection 5.After adopting said structure, whether be convenient to observe puncture owing to needle handle is transparent successful, because being provided with introducing port introducing port place is provided with projection, can be anti-skidding during puncture, avoid complicated operation to cause amount of bleeding big, perhaps make cannula tip deviate from lumen of vessels in the grafting process, puncture failure causes suffering to the patient.

Four, description of drawings: accompanying drawing is a structural representation of the present utility model.

Five, specific embodiment: get involved puncture needle and comprise needle body 1, needle body 1 one ends are sharp-pointed, and the other end is a needle handle 2, and needle handle 2 is connected to one with needle body 1 and is provided with the needle handle lumen 3 of hollow, needle handle 2 is transparent and is provided with introducing port 4 that the opposite side needle handle cavity wall of introducing port 4 is provided with projection 5.

When implementing to get involved puncture, at first seal wire is inserted in the needle handle lumen, needn't send into the metal needle chamber.With thumb with seal wire by being pressed on the introducing port projection, carry out vascular puncture.When being punctured with blood when pouring in needle handle, thumb rubbing seal wire is gently sent into blood vessel, withdraws from puncture needle then and gets final product.
