A channel built-in bone tumor pathological tissue extraction device

Abstract

The invention relates to a channel built-in bone tumor pathological tissue taking-out device. The device is characterized by comprising an implantable channel cannula, a channel needle core, a pathology taking cannula and a channel tail cap; the implantable channel cannula is of a tubular structure with external threads at one end; the end, provided with the external threads, of the implantable channel cannula serves as a tail end, and the other end of the implantable channel cannula serves as a head end; the channel needle core is of a pin-like structure capable of being inserted into the implantable channel cannula; the pathology taking cannula is of a tubular structure capable of being inserted into the implantable channel cannula; the channel tail cap can be arranged at the tail end of the implantable channel cannula. When the device is used, the channel needle core is put into the implantable channel cannula, and the implantable channel cannula and the channel needle core penetrate a pathology taking part together, the implantable channel cannula remains in the puncture part after bone tissue pathology is taken out by the pathology taking cannula, the channel tail cap is arranged on the tail side of the implantable channel cannula, and the implantable channel cannula is screwed and fixed in a bone hole, so that the aim of sealing a puncture approach is fulfilled, and local spread of a tumor tissue of the puncture approach can be effectively blocked.

Description

technical field [0001] The invention relates to an auxiliary device for pathological bone tissue removal surgery, in particular to a channel-built-in bone tumor pathological tissue removal device capable of effectively blocking the local diffusion of tumor tissue through a puncture approach. Background technique [0002] Bone tissue puncture technique is a necessary diagnostic method and plays a very important role in the diagnosis and treatment of bone tumors. However, the current bone tissue puncture technology is still not perfect. After the pathological tissue is taken out, there will be tumor tissue exudation in the puncture approach, and the amount of exudation varies with the intraosseous pressure. Hematomas form, forming new metastases. Especially for bone tumors with high malignant degree, the risk of local tumor metastasis is high. Therefore, it is an urgent problem to be solved in bone tissue puncture technology to minimize the spread of tumor cells to normal ti...
