A puncture positioning device for bone tumor surgery with accurate positioning guidance

Abstract

The invention discloses a bone tumour surgery puncture locating device capable of accurately locating and guiding. The device comprises two mounting plates, the left ends and right ends of the two mounting plates are all connected through connecting frames, connecting rods of the connecting frames are fixedly connected with the inner side faces of the mounting plates, the lower surfaces of the mounting plates are provided with lifting frames, telescopic ends of first telescopic rods of the lifting frames are fixedly connected with the lower surfaces of the mounting plates, fixing ends of the first telescopic rods are provided with bottom plates, the upper surfaces of the bottom plates are provided with mounting holes, fixing bolts are movably inserted in the mounting holes, and the side faces of the mounting plates are provided with sliding grooves. The bone tumour surgery puncture locating device capable of accurately locating and guiding has the advantages that the height can be adjusted, the position and inclination angle of a location sleeve can be adjusted, a puncture needle can be accurately located conveniently, the shaking of the puncture needle is avoided, the puncturing depth can also be precisely controlled, the pain of a patient is reduced, the operation is simple, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a puncture positioning device for bone tumor surgery with accurate positioning and guidance. Background technique [0002] Bone tumors are tumors that occur in bones or their adjunct tissues, and can be divided into benign and malignant. Malignant bone tumors, also known as bone cancer, develop rapidly, with poor prognosis and high mortality. Malignant bone tumors are divided into primary and secondary. Malignant tumors from other tissues or organs in the body metastasize to Bone is a secondary malignant bone tumor, and there is another type of lesion called tumor-like lesions. The tissue of tumor-like lesions does not have the characteristics of tumor cell morphology, but its ecology and behavior are destructive to tumors. It is generally limited and easy to cure , in oncology department puncture biopsy, in the prior art, medical personnel usually carry out puncture wit...

Malignant bone tumors, also known as bone cancer, develop rapidly, with poor prognosis and high mortality. Malignant bone tumors are divided into primary and secondary. Malignant tumors from other tissues or organs in the body metastasize to Bone is a secondary malignant bone tumor, and there is another type of lesion called tumor-like lesions. The tissue of tumor-like lesions does not have the characteristics of tumor cell morphology, but its ecology and behavior are destructive to tumors. It is generally limited and easy to cure , in oncology department puncture biopsy, in the prior art, medical personnel usually carry out puncture with a puncture needle, and the puncture depth can be judged according to the experience of medical personnel, which cannot be accurately positioned, and is likely to cause harm to the patient, and the puncture cannot be punctured during the puncture process. Needle positioning, the puncture needle is easy to shake, increasing the patient's pain
