Description
Technical Field
The utility model belongs to the technical field of medical treatment puncture equipment, concretely relates to thyroid nodule puncture washes pipe needle.
Background
With the development of society, most people do not know where the thyroid is located in daily life, but most people with the 'thick neck disease' are not strange, and the 'thick neck disease' is goiter, which tells people that the thyroid is located at the neck. More specifically, what we commonly know as the "laryngeal prominence" can touch by oneself, and the thyroid gland is located about 2-3 cm below the "laryngeal prominence" and can move up and down along with the laryngeal prominence when swallowing things. The thyroid is shaped like "H", is reddish brown, and is divided into left and right lateral lobes, and the middle is connected by an isthmus. The two side lobes are attached to the outer side surface of the lower part of the larynx and the upper part of the trachea, the middle part of the thyroid cartilage is up to the middle part of the sixth trachea cartilage, the isthmus is mostly positioned in front of the second to fourth trachea cartilages, and some people are not developed. Sometimes, a conical leaf is protruded upwards from the isthmus, and the length is different, and the long one can reach the tongue bone, which is the vestige of embryonic development and is usually gradually degenerated with age, so children are more adults than adults. The thyroid gland is externally covered with a fibrous capsule called thyroid gland tunica, the capsule extends into glandular tissues to divide the gland into lobules with different sizes, the capsule is externally covered with a deep cervical fascia, and ligament-like connective tissues are usually connected between the side lobes of the thyroid gland and the cricoid cartilage, so that the thyroid gland can move up and down along with swallowing. The weight of the thyroid gland is 15-30 g when the thyroid gland is mature in adolescence. The width of each of the two side leaves is about 2 centimeters, the height of each side leaf is 4-5 centimeters, the width of the isthmus is 2 centimeters, and the height of each side leaf is 2 centimeters. The thyroid gland in women is slightly larger than that in men. Under normal conditions, the thyroid gland is very small and thin and therefore is neither visible nor palpable in the neck. If the thyroid gland is touched on the neck, the thyroid gland is considered to be swollen if it is not seen. This degree of swelling is often physiological, especially in female puberty, and is often not the result of the disease, but can sometimes be pathological.
At present, thyroid nodule puncture flushing does not have a special catheter needle, a arteriovenous catheter needle is mostly used clinically, and the joint of the tail end of a plastic channel of the arteriovenous catheter needle and the tail end of a steel needle channel and the joint of the tail end of the steel needle channel and the tail end of a needle core are not in threaded connection, so that the steel needle channel and the needle core automatically retreat when resistance is met in the puncture process, and operation is inconvenient; and the head end of the plastic channel has no side hole, so that the plastic channel is inconvenient to wash and easy to block in the operation process.
