Problems solved by technology

[0004] As mentioned in the above method, no matter what kind of guidance method is used, when the radiation particles are implanted into the target area, it is necessary to puncture from the skin surface through a puncture needle. Uncontrollable, resulting in a deviation between the actual position of the particles after implantation and the designed position, affecting the therapeutic effect

Embodiment 1

[0049] This embodiment discloses a spatial positioning and guiding device for puncture based on a C-arm machine, mainly referring to the guiding and positioning of the puncture needle 2 in particle implantation surgery.

[0050] Such as Image 6 As shown in the figure, the specific structure of the C-arm machine is shown, including a portal frame and a C-arm machine that is arranged on the portal frame and can slide along the top beam of the portal frame. During the seed implantation process, the patient is lying flat, and the operating bed is placed in the middle of the gantry, and the entire gantry can be manually pushed to move to the corresponding area, and then the C-arm is controlled by the computer to adjust the position.

[0051] Wherein, the computer for controlling the whole system is set outside, which is not shown in the figure. There is only one movable display screen on the portal frame, which is connected with the computer and used for displaying data informati...

Abstract

The invention belongs to the field of particle implantation equipment, and discloses a space positioning and guiding equipment based on C-arm machine puncture, which moves in space by being arranged on the movable end of the C-arm machine, and is characterized in that it includes a guide frame and is set on The fixing mechanism on the guide frame, the fixing mechanism is provided with a limiter that guides the linear movement of the puncture needle; the limiter is detachably connected to the fixing mechanism, and can be coincident with the axis of the planned needle path The posterior fixation guides the release of the puncture needle as it penetrates the body.

Description

technical field [0001] The invention belongs to the technical field of particle implantation equipment, and in particular relates to a space positioning and guiding equipment based on C-arm machine puncture. Background technique [0002] The full name of seed implantation is "radioactive seed implantation therapy technology", which is a treatment method that implants a radioactive source into the tumor to destroy the tumor. The particle implant therapy technique involves a radioactive source, the core of which is radiating particles. What is used clinically is a substance called iodine 125. Each iodine 125 particle is like a small sun, and the rays near the center are the strongest, which can minimize the damage to normal tissues. Radioactive seed implantation therapy mainly relies on a stereotaxic system to accurately implant radioactive seeds into the tumor body, and emits continuous, short-distance radiation through a miniature radioactive source, so that the tumor tissu...
