Problems solved by technology

Among them, in the puncture process, bone puncture will also be required, and the existing method is to use a hard puncture needle for bone puncture, but this method often affects the puncture accuracy, resulting in the particle implantation position and design. There is a deviation in the plan, and if ordinary bone penetration equipment is used, the wound will expand. If the bone penetration depth is large, conventional bone penetration equipment cannot be used

Embodiment 1

[0044] This embodiment discloses a nested particle implantation puncture device. Since the needle track of the puncture needle 2 is adjusted according to the number of particles during particle implantation treatment, the puncture needle 2 in this embodiment is more flexible. The puncture is performed with a single positioning method, so that some obstacles can be bypassed, or the particle layout can meet the shape of some abnormal tumors. By cooperating with the existing puncture needle 2, the bone drilling on the puncture path can be realized, and the travel of the puncture needle 2 can be avoided due to bone occupation, and the optimal puncture route can be satisfied to the greatest extent to achieve a better particle layout.

[0045] Among them, such as Figure 3-6 As shown, only the end portion of the puncture needle 2 is shown in the figure, and it can be seen that a drill sleeve 1 is sheathed outside the puncture needle 2 . The drill sleeve 1 has a connecting end, thro...

Embodiment 2

[0052] This embodiment discloses an automatic puncture and bone drill device, such as figure 1 with figure 2 As shown, the structure of nested drill sleeve 1 and puncture needle 2 in Embodiment 1 is adopted, and an automatic mechanism is provided on the outside to realize drilling.

[0053] Specifically, it includes a sliding frame 5 and a fixed seat 3 arranged on the sliding frame 5. The sliding frame 5 in this embodiment is a screw moving mechanism, including two slide rails and a screw drive set in the groove of the frame body. mechanism. The fixed seat 3 includes a connection end with the slide rail, and also has a mounting groove on its upward extension, and the columnar electric mechanism 4 is fixed in the mounting groove by a snap ring.

[0054] The frame body of the entire sliding frame 5 is connected with an external fixing mechanism, which may adopt a structure that is arranged on the ground and has universal wheels that can adjust its position at any time, or a m...

Abstract

The invention belongs to the field of puncture equipment, and discloses a nested type particle implantation puncture device which is used in needle passage arrangement needing bone puncture and comprises a puncture needle and a drill sleeve arranged outside the puncture needle in a sleeving mode. The drill sleeve is provided with a connecting end and is connected with an external structure through the connecting end for rotary drilling. The drill sleeve structure is arranged outside an existing puncture needle, the drill sleeve structure can enter a human body along with the puncture needle, rapid drilling can be performed to form a drill hole for the puncture needle to smoothly pass through when bone penetration is needed, and the drill hole identical to a designed needle passage is kept under the condition that a wound surface is not enlarged, so that the limitation during particle implantation layout is reduced.

Description

technical field [0001] The invention belongs to the technical field of particle implantation equipment, and in particular relates to a nested particle implantation puncture device. 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 tissue is destroyed to the maxim...
