Abstract
The utility model discloses an ablation needle device, which comprises an ablation needle point, an ablation needle tube and a handle from bottom to top in sequence, wherein the ablation needle tube is communicated from top to bottom, the handle is hollow and is communicated with the inside of the ablation needle tube; still include vice needle tubing, vice needle tubing diameter is less than and melts needle tubing and vice needle tubing and sets up in melting inside the needle tubing and vice needle tubing keep away from the one end of melting the needle point and pass the handle inner chamber, vice needle tubing passes through connecting piece and melts needle tubing inner wall fixed connection. The utility model discloses simple structure maneuverability is strong, and the secondary puncture of being convenient for is gone on along the first puncture needle way, reduces the liver risk of bleeding.
Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to an ablation needle device.
Background
Generally speaking, the pus drainage of the cholecystostomy needs to pass through liver tissues, and a patient with normal blood coagulation function generally punctures the pus without causing heavy bleeding.
However, cholecystostomy drainage is necessary for patients with suppurative cholecystitis complicated with septic shock, and therefore, how to reduce the risk of liver bleeding is worthy of study.
In the prior art, a puncture path of a liver is firstly ablated, so that the liver is partially free from blood supply, a needle is inserted along the ablated liver (without blood supply) through a pigtail tube, but the needle is withdrawn after the ablation needle is cauterized for the first time, and the needle track is difficult to control on the path of the first puncture needle for the second time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a double-channel structure melts needle device can play the effect of guide wire location and melting the needle simultaneously at the puncture in-process.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an ablation needle device sequentially comprises a device body and a handle from bottom to top, wherein the device body is in a needle body shape, and the handle is fixedly connected with one end of the device body, which is far away from a needle tip;
the device also comprises an ablation needle line cavity channel and a guide wire cavity channel, wherein the ablation needle line cavity channel and the guide wire cavity channel penetrate through the device body and the handle from bottom to top and are parallel to each other;
the ablation needle line is matched with the ablation needle line cavity, and the guide wire is matched with the guide wire cavity.
Preferably, the electric wire and the power connector are further included, one end of the electric wire is arranged in the ablation needle wire cavity, and the other end of the electric wire is electrically connected with the power connector.
Preferably, the device body is made of stainless steel materials or tungsten-molybdenum alloys.
Preferably, the handle is made of an insulating material.
Further, the handle is spindle-shaped.
The utility model discloses following beneficial effect has:
the guide wire can be inserted along the guide wire cavity in the using process, so that the guide wire can be left at the needle channel position of the first puncture after the device is withdrawn, and thus the needle channel of the second puncture is consistent with the needle channel of the first puncture, and the liver bleeding risk is reduced.

FIG. 2 is a schematic cross-sectional view of the ablation needle cannula taken along plane A-A'.
In the figure: 1-device body, 2-handle, 3-ablation needle and thread cavity, 4-guide thread cavity, 5-power connector and 6-wire.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the ablation needle device sequentially comprises a device body 1 and a handle 2 from bottom to top, wherein the device body 1 is in a needle body shape, and the handle 2 is fixedly connected with one end of the device body 1, which is far away from a needle tip;
in order to pass through the ablation needle wire and the guide wire, the utility model also comprises an ablation needle wire cavity channel 3 and a guide wire cavity channel 4, wherein the ablation needle wire cavity channel 3 and the guide wire cavity channel 4 both penetrate through the device body 1 and the handle 2 from bottom to top and are parallel to each other; and simultaneously, the utility model discloses still including melting the needle line and leading the seal wire, melt the needle line and melt 3 looks adaptations in needle line chamber, lead the seal wire and lead 4 looks adaptations in silk chamber.
For melting the circular telegram of needle and line, the utility model discloses still include electric wire 6 and power connection 5, 6 one end of electric wire set up in melting needle and line chamber and say 3, the 6 other ends of electric wire and 5 electric connection of power connection.
Preferably, the device body 1 is made of stainless steel material or tungsten-molybdenum alloy. Meanwhile, the handle 2 is made of an insulating material.
The handle 2 is in a spindle shape for facilitating the operation of medical staff.
Can insert the guide wire along guide wire chamber 4 in the use for the guide wire can the utility model discloses wholly leave the needle of puncture way position for the first time after withdrawing from, so the puncture needle way for the second time is unanimous with the puncture needle way for the first time, reduces the liver risk of bleeding.
Of course, the present invention may have other embodiments, and those skilled in the art may make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the appended claims.
