Body surface positioner capable of being used in multiple purposes under assistance of X-ray CT

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a body surface positioner which can be used for multiple purposes under the assistance of X-ray CT.

Background

In vivo lesion diagnostic determinations have been a difficult problem for clinical and imaging purposes. With the development of medical imaging and the continuous improvement of disease understanding, in-vivo lesions are often seen in an image, and on the basis of specific property judgment, the properties of the lesions can be primarily assumed due to obvious imaging characteristics in part of the conditions. For atypical cases, diagnosis is difficult. The differential diagnosis of the in-vivo focus has become one of the important matters of the daily work of clinicians, and the technique of the percutaneous in-vivo focus puncture under the guidance of CT/X rays is exactly suitable for the requirement, thereby providing a better means for further diagnosing the in-vivo focus property. Because imaging is less reliable than pathology in diagnosis of disease such as in vivo focus, in recent years, along with development of CT/X-ray equipment, improvement of pathology technology and improvement of puncture needles, the diagnosis qualitative accuracy of pathology in percutaneous in vivo focus puncture biopsy under CT/X-ray guidance is greatly improved, and the imaging method is an important diagnosis technology in the interventional radiology field, is recognized as one of important methods for diagnosis and differential diagnosis of disease of in vivo focus, and has been widely applied to clinic. At present, B ultrasonic guided puncture can be used for tumors which are close to the body surface and have large tumor volume, and B ultrasonic with the tumor body diameter below 3cm is not easy to position. Because of the characteristics of the B-ultrasonic technology and the operation method, the B-ultrasonic guidance has larger limitation, and the occurrence of CT guidance provides possibility for solving the problem. The method has the advantages of small damage to in vivo tissues, safety, reliability, accurate positioning, high accuracy, few complications and unique value for percutaneous in vivo focus puncture biopsy under CT guidance.

However, there are a number of problems with the body surface positioners currently in clinical work in the practical use: when puncture positioning is performed, the shape and the form cannot be fully adapted, so that the puncture positioning point is deviated; in the needle insertion process, the situation that bones are touched or important blood vessels need to be avoided, so that the original needle insertion route cannot be normally performed, and the puncture route is forced to be repeatedly adjusted, so that the patient suffers more unnecessary pains; the traditional body surface positioner can not accurately solve the problem of the needle inserting angle of the puncture needle, and can only judge by depending on the experience of an operator in many cases; adjusting the needle insertion angle may require multiple CT/X-ray scans, also increasing the risk of the patient receiving radiation, etc. The uncertain factors not only increase the puncture risk or radiation risk of a patient, but also often lead to incapability of smoothly matching with the puncture biopsy, and bring inconvenience to medical staff and influence the medical working quality.

Disclosure of utility model

The embodiment of the utility model aims to provide a body surface positioner which can be used for multiple purposes under the assistance of X-ray CT so as to solve the problems of poor conformality, inaccurate positioning, long puncture time and large tissue trauma in the clinical work of the existing body surface positioner.

The embodiment of the utility model is realized in such a way that the body surface locator can be used for multiple purposes under the assistance of X-ray CT, and comprises: the steel wires are provided with a plurality of steel wires, silica gel is fixedly arranged at two ends of the plurality of steel wires, and the silica gel can connect the two ends of the steel wires; the PVC frame is connected with silica gel on two sides and is arranged on one side of the steel wire, and the hooked metal wire is hung on the PVC frame and is arranged on the steel wire in a sliding manner, and can stably slide along the PVC frame and the steel wire to position the body surface.

Preferably, the whole length of the positioner formed by the steel wire, the silica gel and the PVC frame is 15 cm, and the whole width is 15 cm.

Preferably, the steel wire and the hooked metal wire are made of soft alloy materials and can be attached to human skin.

The body surface locator which can be used for multiple purposes under the assistance of X-ray CT has the following effects that firstly, the body surface location of a focus in the body is accurately realized; secondly, the body surface has strong conformability, and can be adjusted according to different body parts or body types of patients; thirdly, the needle inserting angle is accurate, and the radiation quantity increase caused by multiple scanning is avoided; fourth, the locating point and the angle are accurately controlled, so that unnecessary pain caused by repeated adjustment of the needle inserting route is avoided for the patient. The operation is simple, and the practicability is strong.
