Description

Technical Field

[0001] The present invention relates to the field of radioactive particle implantation and puncture biopsy surgery, and particularly to a laser-assisted positioning and guiding platform template system for radioactive particle implantation and puncture biopsy surgery. Background Art

[0002] Radioactive particle implantation surgery is a new treatment method developed clinically in recent years. It has a wide range of applications and remarkable curative effects, bringing hope to patients who cannot undergo surgical resection. Since such surgical operations require positioning under CT guidance, using a special template to guide the puncture needle into the tumor and then using the needle core to deliver radioactive particles to the tumor, realizing rapid positioning of the tumor area and quickly and stably locking the fixed arm are the technical points for improving the quality of this surgery. Existing particle implantation systems have problems such as complex positioning steps, cumbersome angle adjustment and locking steps of the fixed arm, and poor stability, which is a main reason for the extension of the operation time, the decline of implantation accuracy and even failure. The same problems also occur during the implementation of tissue puncture biopsy technology. Therefore, the above-mentioned technical problems are problems that need to be solved urgently by those skilled in the art. Summary of the Invention

[0003] To solve the above technical problems, the technical solution provided by the present invention is: a laser-assisted positioning and guiding platform template system for surgical use, including: a slideway, on which a fixed frame that can move along the slideway is provided, and on the fixed frame, a fixed arm that can move up and down along the fixed frame is provided. At the end of the fixed arm far from the fixed frame, a detachable guiding platform is provided, and a detachable needle track template is embedded in the guiding platform; the needle track template is circular and is embedded in the middle of the guiding platform. A laser emitter and a prism reflection device are arranged in the guiding platform. The laser emitter is arranged along the Y-axis of the needle track template on one side of the needle track template, and the prism reflection device is arranged at the laser outlet end of the laser reflector, so that the laser emitted by the laser reflector is emitted outward along the X-axis direction of the needle track template. A laser emission switch, a physical level, and an electronic inclinometer are also arranged on the guiding platform.

[0004] Further, the physical level is embedded in the upper part of the guiding platform, and the electronic inclinometer is attached to the guiding platform through a neodymium magnet magnetic point embedded in the upper part of the guiding platform.

[0005] Further, a laser emitter calibration shift is arranged at one end of the laser emitter, and the laser emitter calibration shift is exposed outside the guiding platform.

[0006] Further, the number of the slideway, the fixed frame, and the fixed arm is two. The fixed arms are connected to both sides of the guiding platform along the laser emission direction, and fixed arm connection points are arranged on the guiding platform.

[0007] Further, spiral fine-tuning fixing points are also provided at the four corners of the guiding platform.

[0008] Further, the fixing frame includes a slider cooperating with the slideway, a base disposed on the upper part of the slider, and a fixing rod disposed on the upper part of the base, and the fixing arm is connected to the upper part of the fixing rod.

[0009] Further, the fixing arm includes a fixing arm main body connected to the guiding platform, a fixing rod clamping member is disposed at the other end of the fixing arm main body, and a locking knob is disposed on the fixing rod clamping member.

[0010] Further, the fixing arm main body is a universal shaft composed of a plurality of bowl-shaped structural members, a tension wire is disposed inside the fixing arm main body, a gear scroll for winding the wire is disposed between the fixing arm main body and the fixing rod clamping member, and a knob is disposed on the gear scroll.

[0011] Further, a needle track template installation groove is provided on the guiding platform, and several elastic locking bumps are provided on the inner wall of the template installation groove.

[0012] Further, the laser emitter is a green cross laser emitter.

[0013] After adopting the above scheme, the present invention has the following advantages: In the operation process of the conventional particle implantation system, the template may pop out and shift; the adjustment angle is narrow, the multi-point locking steps are cumbersome, and displacement deviation often occurs after locking, so repeated calibration is required; due to the lack of fine-tuning support points, displacement will occur again during the operation process, resulting in reduced operation accuracy and prolonged operation time.

[0014] However, the present invention (1) can stably clamp the needle track template to avoid popping out and shifting; (2) the fixing arm has a high degree of freedom of movement and can achieve single-point locking and overall fixing, shortening the system preparation time before implantation and improving work efficiency; (3) the spiral fine-tuning fixing points can be used for angle fine-tuning of the guiding platform and intraoperative support; (4) the green laser emission point is located on the X axis of the needle track template, and under this guidance, it can cooperate with the CT red laser positioning line to quickly locate the tumor area; (5) the physical level combined with the electronic inclinometer adsorbed by the magnetic points can accurately level and adjust the required angle; (6) the slideway design can realize the overall displacement of the system, reduce the discomfort caused by moving the patient, and avoid re-CT positioning, thereby reducing the radiation to the patient.
