A multi-purpose body surface locator assisted by X-ray CT

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a multi-purpose body surface locator assisted by X-ray CT.

Background Art

The diagnosis of in vivo lesions has always been a difficult problem for clinical and imaging. With the development of medical imaging and the continuous improvement of the understanding of diseases, in vivo lesions are often seen in imaging images. In terms of their specific nature, in some cases, their nature can be preliminarily inferred due to obvious imaging characteristics. For atypical cases, it is difficult to make a diagnosis. The differential diagnosis of in vivo lesions has become one of the important contents of the daily work of clinical physicians. The technology of percutaneous in vivo lesion puncture under CT/X-ray guidance just meets this requirement and provides a better means for further diagnosis of the nature of in vivo lesions. Because the diagnostic accuracy of imaging in diseases such as in vivo lesions is not as reliable as pathology, in recent years, with the development of CT/X-ray equipment, the improvement of pathological technology and the improvement of puncture needles, the qualitative accuracy of pathological diagnosis of percutaneous in vivo lesion puncture biopsy under CT/X-ray guidance has been greatly improved, becoming an important diagnostic technology in the field of interventional radiology. It is recognized as one of the important methods for the diagnosis and differential diagnosis of in vivo lesions and has been widely used in clinical practice. At present, ultrasound can be used to guide puncture for tumors that are close to the body surface and have a large volume, but it is difficult to locate tumors with a diameter of less than 3 cm by ultrasound. Due to the characteristics of ultrasound technology and operation methods, ultrasound guidance has great limitations, and the emergence of CT guidance has made it possible to solve this problem. It has little damage to the body's tissues, is safe, reliable, accurately positioned, has a high accuracy rate, and has few complications. CT-guided percutaneous puncture biopsy of body lesions has its unique value.

However, the surface locators currently used in clinical work have many problems in actual use: when performing puncture positioning, they cannot fully conform to the body surface morphology, resulting in deviations in the puncture positioning point; during the needle insertion process, the original needle insertion route cannot be carried out normally due to touching bones or needing to avoid important blood vessels, and the puncture route is forced to be adjusted repeatedly, causing the patient to suffer more unnecessary pain; traditional surface locators cannot accurately solve the problem of puncture needle insertion angles, and in many cases can only rely on the operator's experience to make judgments; adjusting the needle insertion angle may require multiple CT/X-ray scans, which also increases the risk of radiation exposure for patients, etc. The above uncertain factors not only increase the puncture risk or radiation risk of patients, often leading to the inability to cooperate smoothly in puncture biopsy, but also bring many inconveniences to medical staff and affect the quality of medical care.

Utility Model Content

The purpose of the embodiment of the utility model is to provide a multi-purpose body surface locator assisted by X-ray CT to solve the problems of poor conformality, inaccurate positioning, long puncture time and large tissue trauma encountered by existing body surface locators in clinical work.

The embodiment of the utility model is implemented as follows: a body surface locator that can be used for multiple purposes under the assistance of X-ray CT, comprising: a steel wire, wherein a plurality of the steel wires are provided, and silica gel is fixedly provided at both ends of the plurality of steel wires, and the silica gel can connect the two ends of the steel wire; a PVC frame, which is connected to the silica gel on both sides and is provided on one side of the steel wire, and a metal wire with a hook is hung on the PVC frame, and the metal wire with a hook is slidably provided on the steel wire, and the metal wire with a hook can stably slide along the PVC frame and the steel wire to perform body surface positioning.

Preferably, the overall length of the positioner composed of the steel wire, silica gel and PVC frame is 15 cm, and the overall width is 15 cm.

Preferably, the steel wire and the hooked metal wire are made of soft alloy material and can fit human skin.

The multi-purpose body surface locator provided by the utility model with the assistance of X-ray CT has the following effects: first, accurate body surface positioning of the lesion in the body; second, strong body surface conformability, which can be adjusted according to different body parts or patient body shapes; third, accurate needle insertion angle, avoiding the increase of radiation caused by multiple scans; fourth, accurate control of the positioning point and angle, avoiding unnecessary pain caused by repeated adjustment of the needle insertion route for the patient. It is simple to operate and highly practical.
