Problems solved by technology

The methods currently used for these two medical X-ray detectable wires are limited to weaving into gauze. The gauze (or surgical towel or liquid-absorbing material) used in some operations or special operations is very small, and it is difficult to weave the X-ray into the gauze. Optically detectable threads are placed over these very small gauzes (or drapes or absorbent materials) so that X-rays cannot detect whether gauze or drapes are left in the patient

Abstract

The invention discloses a medical X-ray detectable sewing thread. The medical X-ray detectable sewing thread comprises a sewing thread body, wherein the sewing thread body comprises a plurality of core threads and covered filaments, the core threads are formed by complex fibers made of barium sulfate and high polymer materials, the covered filaments are formed by a plurality of chemical fiber filaments, and the covered filaments cover outer surfaces of the core threads along the direction of S-twist, Z-twist, or a cross of the S-twist and the Z-twist; covering twists of the covered filaments are 2-16 twists; the cross section of the sewing thread is round or oval; the content of the barium sulfate in the complex fibers is larger than or equal to 55%. The medical X-ray detectable sewing thread can be weaved or sewed (or welded by using ultrasonic waves) into a gauze or an operation towel, whether the gauze or the operation towel is left in the body of a patent can be found through X-ray examination after operations, and medical negligence caused by the gauze or the operation towel left in the body of the patent is avoided.

Description

technical field [0001] The invention relates to a medical X-ray detectable sewing thread. Background technique [0002] During medical operations, many gauzes (or surgical drapes) are used to absorb the blood produced by the wound during the operation. During the tense operation, it is impossible to count the number of gauze (or surgical drape) correctly. In recent years, there have been many medical accidents and disputes about gauze left in the body of the operator. Adding medical X-ray detectable lines to surgical gauze (or surgical towel) can avoid the occurrence of such medical accidents. [0003] At present, there are two kinds of medical X-ray detectable lines at home and abroad. One is made of barium sulfate powder and polyvinyl chloride as the main material to make monofilament; the other is made of barium sulfate powder and polypropylene as the main material and processed into multifilament. The methods currently used for these two medical X-ray detectable wires...
