Description

Technical Field

[0001] The utility model belongs to the technical field of surgical instruments, and in particular relates to a soft guide wire positioning device. Background Art

[0002] The breast tumor localization soft guide wire is a medical device used to locate breast tumors. It is usually used before breast surgery. Its main purpose is to help surgeons accurately find and remove tumors or diseased tissues in the breast during surgery. During surgery, the guide wire must be accurately positioned to ensure the success rate of the operation.

[0003] At present, commonly used positioning guide wires are generally made of metal materials. Although these metal guide wires can achieve basic positioning of tumors during use, they also have some obvious defects and inevitable risks. First, the metal guide wire is easy to cause damage to surrounding tissues during insertion, increasing the patient's preoperative pain and potential risks. In addition, after positioning, the metal guide wire is exposed outside the body, which is not easy to fix and can easily cause trauma. The preoperative waiting time and the exposed metal guide wire increase the patient's fear and restrict the patient's activities. Some even cause the guide wire to be pulled and slipped due to improper operation while waiting for surgery. All these disadvantages are not conducive to the humanistic care of individualized treatment. During the operation, the surgeon may find it difficult to perform precise positioning and adjustment due to the rigidity of the guide wire, thus affecting the accuracy and safety of the operation. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A soft guide wire positioning device, comprising:

[0007] Plastic handle;

[0008] A metal tube, wherein the metal tube is fixedly connected to the outside of one side of the plastic handle;

[0009] A limiting mechanism is installed on the outside of one side of the plastic handle. The limiting mechanism includes a threaded seat, a threaded sleeve and a limiting sleeve. The threaded seat is fixedly connected to the outside of one side of the plastic handle, the inside of the threaded seat is screwed together with the threaded sleeve, and the outside of the threaded sleeve is fixedly connected to the limiting sleeve.

[0010] Preferably, the threaded sleeve is screwed into the interior of the threaded seat, and the threaded sleeve is threadedly connected to the threaded seat.

[0011] Preferably, a pressing mechanism is inserted into the interior of the plastic handle.

[0012] Preferably, the pressing mechanism includes a pressing airbag, a pressing strip and a double-strand wire, the pressing airbag is inserted inside the plastic handle, one side of the pressing airbag is fixedly connected to the outside of the pressing strip, the pressing strip is inserted inside the inside of the pressing strip, and one side of the double-strand wire is fixedly connected to the outside of the needle tip.

[0013] Preferably, the pressing airbag is made of elastic plastic material, the needle tip is in the shape of a fishhook, and the double-stranded wire is horizontally inserted inside the pressing strip.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model arranges the threaded seat, threaded sleeve, pressing airbag and pressing strip so that the double-strand wire can be placed flatly inside the pressing strip. When the limiting sleeve is unscrewed, the pressing airbag can be operated. After pressing, the needle tip will curl and pierce into the tumor and be fixed. After that, the doctor can pull out the pressing mechanism and the metal tube to expose the medical double-strand wire connected to the guide wire to the chest wall and fix it. In this way, the metal guide wire is implanted in the tumor, and the connected or exposed part is the soft double-strand wire. This design effectively reduces unnecessary trauma and improves the comfort of the patient. BRIEF DESCRIPTION OF THE DRAWINGS
