A combined tool for thyroid puncture

Abstract

The invention discloses a combination tool for thyroid puncture. The combination tool comprises a negative pressure syringe, wherein a puncture needle is connected to one end of the negative pressuresyringe, and a liquid collection bottle and an adjustable puncture fixing device for limiting the puncture position are disposed under the negative pressure syringe. The adjustable puncture fixing device comprises a sleeve neck and a movable connection component, wherein the movable connection component comprises a first perforated plate integrally formed with the negative pressure syringe, two second perforated plates arranged in the left and right direction and integrally formed with the sleeve neck, and fastening screws that are used for fixing the first perforated plate and the second perforated plates. Two ends of the sleeve neck are connected with a velcro male face and a velcro female face, respectively, so that the function of repeated aspiration of the thyroid nodules and cysts ofa patient can be achieved, and furhter the burden of pains of the patient by multiple insertion and puncture can be alleviated. During the thyroid puncture of the patient, the combination tool can maintain the relative fixation between the thyroid puncture combination tool and the thyroid position of the patient and ensure the accuracy of diagnosis and treatment results.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a combined tool for thyroid puncture.

[0002] For thyroid nodules and cysts, puncture must be used to diagnose pathological specimens obtained by puncture of thyroid nodules, or to extract and treat cyst fluid. Therefore, the thyroid puncture needle is an important medical device. The existing thyroid puncture needle has a simple structure and a Relatively simple, just as the application number 201320077269.0 is the invention of a new type of thyroid puncture needle, the invention has a simple structure, and the connection of the negative pressure device is controlled by an attached connection switch, which is stable and easy to use, reducing the work difficulty of medical staff. It improves the operation efficiency and is suitable for clinical promotion and application. However, in the process of use, there are often some problems as follows:

[0003] (1) After the puncture needle is inserted into the patient's thyroid gland once, only one suction operation can be performed, so the amount of thyroid biopsy tissue obtained by one puncture is also certain. Sometimes the patient's cyst is relatively viscous, and it cannot be completely extracted by one suction. It needs to be sucked clean, which requires multiple puncture and suction operations, which will bring more pain to the patient while bringing trouble to the medical staff;

[0004] (2) There is no fixing device for limiting the position of the puncture needle, so during the thyroid puncture process, the medical staff need to use their hands to limit the position of the puncture needle, but the medical staff also need to control the negative pressure device to perform negative pressure suction Therefore, it is difficult for a medical staff to complete the thyroid puncture operation, and it is easy to cause the puncture position to be misplaced due to the shaking of the hands of the medical staff, resulting in unreliable follow-up diagnosis and treatment results.
