Description

Adjustable radiofrequency ablation needle for thyroid and breast

technical field

The utility model relates to the field of medical equipment, in particular to an adjustable radiofrequency ablation needle for thyroid gland and mammary gland.

Background technique

In the treatment of thyroid nodules and benign breast tumors, radiofrequency ablation can be used for minimally invasive treatment. When radiofrequency ablation is used to treat thyroid nodules and benign breast tumors, in order to achieve the purpose of precise ablation of multiple nodules and tumors in the same patient, the thyroid and breast nodules and tumors are multiple and different in size. , because the currently used ablation needles cannot adjust the ablation diameter, so they cannot cover and ablate all nodules and tumors at one time, and there are certain defects.

Contents of the invention

The utility model aims to solve the above-mentioned deficiencies in the prior art, and proposes an adjustable thyroid gland with simple structure, ingenious design, reasonable layout, and the ability to adjust the ablation diameter according to the actual situation and needs, in order to achieve a good ablation effect. Breast radiofrequency ablation needle.

The technical solution of the utility model is: an adjustable radiofrequency ablation needle for thyroid and breast, including a needle body 1, characterized in that: the tail end of the needle body 1 is fixedly connected in the handle 2, and The tail end of the body 1 is also connected with a wire 3, and a sterile heat-insulating insulating sleeve 4 is movably socketed outside the needle body 1. An elastic ring 5 is arranged outside the aseptic heat-insulating insulating sleeve 4, and an elastic ring 5 is arranged inside the handle 2. There are a plurality of annular grooves 6 matching the elastic ring 5, and the annular grooves 6 are equidistantly distributed along the length direction of the sterile heat-insulating insulation sleeve 4, and marks are provided on the sterile heat-insulating insulation sleeve 4 The line 7 is provided with a viewing window 8 on the handle 2 , and the marking line 7 is located within the range of the viewing window 8 , and a plurality of scale lines 9 matching the marking line 7 are also provided on the handle 2 .

Compared with the prior art, the utility model has the following advantages:

The adjustable thyroid and breast radiofrequency ablation needle with this structure has a simple structure, ingenious design, and reasonable layout. The goal of one-time coverage of nodules and tumors that need to be ablated is achieved, and the adjustment process is simple and easy, the movement of the overall structure is flexible and reliable, and the size of nodules and tumors that need to be ablated can be quickly adjusted in multiple levels. Moreover, its manufacturing process is simple and its manufacturing cost is low, so it can be said that it has many advantages, and is especially suitable for popularization and application in this field, and its market prospect is very broad.

Fig. 1 is a schematic structural view of an embodiment of the utility model.

detailed description

The specific embodiment of the utility model will be described below in conjunction with the accompanying drawings. As shown in Figure 1: an adjustable thyroid and breast radiofrequency ablation needle, including a needle body 1 as a base, the needle body 1 is wrapped with heat insulating material, and the needle body 1 is equipped with a circulating water system to Prevent the temperature of the needle tip from being too high; the tail end of the above-mentioned needle body 1 is fixedly connected in the handle 2, and the tail end of the needle body 1 is also connected with a wire 3, and a sterile heat-insulating insulating sleeve 4 is movable outside the needle body 1 , and this aseptic heat-insulating insulating sleeve 4 can move relative to the needle body 1 in the axial direction, and an elastic ring 5 is connected to the outer sleeve of the aseptic heat-insulating insulating sleeve 4, while a plurality of The annular groove 6 matched with the elastic ring 5, and the above-mentioned multiple annular grooves 6 are equidistantly distributed along the length direction of the sterile heat-insulating insulating sleeve 4, and a marking line is also provided on the sterile heat-insulating insulating sleeve 4 7, and a window 8 is opened on the handle 2, and the marking line 7 is within the scope of the window 8, and a plurality of scale lines 9 matching the marking line 7 are also provided on the handle 2.

The working process of the adjustable thyroid and mammary gland radio frequency ablation needle in the embodiment of the present invention is as follows: during the operation, the surgeon holds the handle 2 to perform the puncture operation, and the end of the needle body 1 is pierced into the thyroid nodules and For benign breast tumors, adjust the length of the exposed needle body 1 (that is, the effective part of the ablation needle) according to the size of the thyroid nodules and benign breast tumors that need to be ablated, and then adjust the size of the ablation diameter of the needle body after electrification;

The specific adjustment process is: the user presses the aseptic heat-insulating insulating sleeve 4 in the window 8 and drives it to move along the length direction of the needle body 1. Since the needle body 1 does not move relative to the handle 2, the above actions will make the needle body 1 move. The exposed length of the end part of the body 1 changes. During the movement, the elastic ring 5 will enter the next-level annular groove 6, and the marking line 7 on the sterile heat-insulating insulating sleeve 4 will move to a certain moment. The position corresponding to the scale line 9, the operator can read the length value of the exposed part of the current needle body 1 through the reading on the scale line 9, and the length value is the ablation diameter; the operator can perform ablation according to the required ablation diameter Adjust until the marking line 7 moves to the scale line 9 corresponding to the required ablation diameter and stops; due to the existence of the matching elastic ring 5 and the annular groove 6, the length of the exposed part of the needle body 1 (that is, the ablation diameter) can be guaranteed. accuracy.

For example, the length range of the effective part of the needle body 1 is 5-15mm, and the distances are divided into 5mm, 7mm, 10mm, and 15mm.
