Tumor tissue specimen automatic selecting device in bone and soft tissue tumor needle biopsy

Abstract

The invention belongs to the technical field of medical instruments, and discloses an automatic tumor tissue specimen selecting device in a bone and soft tissue tumor needle biopsy operation, a metal cup for containing specimens is placed in a semitransparent liquid storage tank, a vertical clamping groove is formed in the metal cup, and a cross-shaped crossed blade is fixed to the metal cup through the vertical clamping groove; a hexagonal prism is fixed to the middle of the cross-shaped crossed blade and connected with a transparent circular cover plate, and a manual rotating shaft is fixed to the transparent circular cover plate. The semitransparent liquid storage tank is provided with an inlet hole and an outlet hole, the inlet hole and the outlet hole are provided with switches, a circular opening is formed right above the semitransparent liquid storage tank, and the position of the inlet hole in the semitransparent liquid storage tank is higher than that of the outlet hole. According to the invention, tumor tissue specimens required in a needle biopsy operation can be quickly separated from other unwanted tissues and blood clots, so that useful tumor tissue specimens can be conveniently and quickly selected, and the burden of a surgeon is relieved; the operation time is shortened, and the operation cost of a patient is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an automatic selection device for tumor tissue specimens in bone and soft tissue tumor puncture biopsy. Background technique [0002] At present, bone and soft tissue tumors are diseases that seriously endanger human health and life. In recent years, the incidence rate has gradually increased. Primary malignant bone tumors are more common in adolescents and middle-aged people. Histiocytoma, chordoma, etc. Common soft tissue malignant tumors are synovial sarcoma, fibrosarcoma, liposarcoma, rhabdomyosarcoma, etc. These malignant tumors need to be confirmed by needle biopsy before surgery or chemotherapy. [0003] Both bone tumors and soft tissue tumors have large heterogeneity, that is, the components are very complex, and the tumor tissue components that can be used to clarify the nature of the tumor often only account for a small part of the tumor volume. The...

Problems solved by technology

[0006] (2) During the needle biopsy operation, it is often necessary to suspend the puncture operation, spend a lot of time cleaning and selecting tumor tissue specimens useful to the naked eye, and even often need to repeatedly puncture and repeatedly select, which not only increases the workload of the surgeon, but also Delay the patient's operation time and increase the patient's operation cost
