Problems solved by technology

In the process of manual adjustment, the angle error at the end of the template is difficult to guarantee, and the accuracy is low, which in turn leads to low accuracy of particle implantation position
And the process of manual adjustment is very time-consuming

Embodiment Construction

[0017] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0018] see Figure 1 to Figure 4 , an auxiliary automatic positioning mechanism for tumor radiotherapy particle implantation, including a base 1, a horizontal linear module, an arc guide rail, an arc sliding module, a vertical linear module, a support arm 7, a pan platform 8, and a rudder machine 9 and template 11.

[0019] The base 1 is installed on the bed plate of the CT bed with mounting screws. The base 1 adopts a fully symmetrical structure and can be installed on the left or right side of the CT bed according to the work requirements to realize the bilateral working position of the mechanism. It is guaranteed that the mechanism can be freely fixed on the left and right sides of the CT bed, which increases the working space of the mech...

Abstract

The invention discloses an auxiliary automatic positioning mechanism for tumor radiotherapy seed implantation. The auxiliary automatic positioning mechanism comprises a base, a horizontal linear module, an arc-shaped guide rail, an arc-shaped sliding module, a vertical linear module, a support arm, a cradle head, a steering engine and a template; the horizontal linear module is installed on the base, and a sliding block I moving left and right is arranged on the horizontal linear module; the lower end of the arc-shaped guide rail is fixedly connected to the sliding block I, and the horizontal projection of the arc-shaped guide rail extends in the front-and-back direction; the arc-shaped sliding module is installed on the arc-shaped guide rail; the vertical linear module is installed on one side of the arc-shaped sliding module, and a sliding block II moving up and down is arranged on the vertical linear module; the support arm laterally stretches out, and the upper end of the support arm is fixedly connected to the sliding block II; the cradle head is fixedly connected to the lower end of the support arm; the steering engine is rotatably connected with the cradle head; the template and the steering engine are fixedly connected through a rigid connecting part, and an electromagnetic position finder sensing contact, an inclinometer and a proximity switch are installed on the rigid connecting part. The auxiliary automatic positioning mechanism is efficient, precise, safe and convenient to operate.

Description

technical field [0001] The invention relates to the field of medical equipment, belongs to the cutting-edge discipline intersecting the fields of machinery and medical radiotherapy, and is an automatic positioning auxiliary device for particle implantation radiotherapy of body tumors. Background technique [0002] In the treatment of body tumors, as an important treatment method, radiotherapy has been paid more and more attention. The process of radiotherapy is to irradiate tumor lesion tissue with various high-energy rays to inhibit and kill cancer cells. The current radiation therapy for tumors can be divided into teletherapy and brachytherapy according to its different methods. Teleradiotherapy is to use X-ray therapy machine to focus the rays outside the human body to irradiate the body surface or tumor parts in the body for a short time, so as to kill tumor cells. The representative treatment method is external radiation. Brachytherapy uses radionuclides close to the ...
