An electromagnetic positioning navigation particle implant trocar for interventional surgery

Abstract

The present invention specifically relates to an electromagnetic positioning navigation particle implantation trocar used for interventional operation. The electromagnetic positioning navigation particle implantation trocar comprises a puncture trocar, a hollow particle thimble and an electromagnetic positioning assembly; the puncture trocar comprises a hollow internal needle and an external needle which is through back and forth; the internal needle is pluggably disposed in the external needle; the front end of the internal needle is closed; the rear end of the internal needle is provided with an opening; the front end of the particle thimble is closed; the rear end of the particle thimble is provided with an opening; the particle thimble can be movably disposed in the external needle when cooperated with the external needle; the electromagnetic positioning assembly comprises an electromagnetic positioning sensor; and the electromagnetic positioning sensor can be pluggably disposed in the internal needle or in the particle thimble. Spatial positions of implanted particles can be objectively positioned in real time, particle distribution can be more accurate, and use cost can be reduced.

Description

【Technical field】 [0001] The present invention relates to medical equipment, in particular to an implanted trocar for electromagnetic positioning and navigation particles used in interventional surgery. The above-mentioned interventional surgery can be three-dimensional surgery or ultrasonic surgery. 【Background technique】 [0002] There is a big problem in the current ultrasound-guided or three-dimensional image-guided particle implantation surgery, that is, there is generally a perfect particle implantation plan before the operation, but when placing the particles during the operation, it is difficult to display the needle tip and the particle space The position is not easy to locate, so that the particle placement position cannot meet the requirements of the preoperative plan, and the operation cannot be evaluated in real time, and the surgical effect is not ideal. The reason for this problem is that the particle thimble in the existing radiation seed implantation operati...

Problems solved by technology

[0002] There is a big problem in the current ultrasound-guided or three-dimensional image-guided particle implantation surgery, that is, there is generally a perfect particle implantation plan before the operation, but when placing the particles during the operation, it is difficult to display the needle tip and the particle space The position is not easy to locate, so that the particle placement position cannot meet the requirements of the preoperative plan, and the operation cannot be evaluated in real time, and the surgical effect is not ideal

The reason for this problem is that the particle thimble in the existing radioactive particle implantation surgery can only play the role of pushing the particle into the lesion without the function of indicating the location of the particle, and the situation is more complicated in the implementation of the particle implantation operation. , the doctor cannot detect the misplaced particles in time and correct the operation plan, which seriously affects the effect of the particle implantation operation
