Honeycomb-type grating filler automatic filling device

Abstract

The invention discloses a honeycomb type grating filler automatic loading device, which includes a support, a housing, a push rod assembly, a drive rod and a cylinder, wherein the housing is arranged on the support, and there is a storage cavity inside the housing, and the push rod assembly accommodates In the storage cavity, the push rod assembly includes a push rod guard and guide mechanism, a push rod, a clutch control mechanism and a sliding guide mechanism. The push rod guard and guide mechanism is fixed in the storage cavity, and the push rod is slidably stored on the push rod guard and guide mechanism , the clutch control mechanism is set on the sliding guide mechanism, and the clutch control mechanism is slidably arranged in the storage cavity along with the sliding guide mechanism. The sliding guide mechanism is connected with the driving rod, and the driving rod is connected with the cylinder. Connection or separation, when the clutch control mechanism is connected with the push rod, it drives the push rod to move together. The present invention can automatically and selectively control the movement or non-movement of the push rod, thereby automatically and selectively pushing the filler into the honeycomb grating.

Description

technical field [0001] The invention relates to a medical treatment instrument, in particular to a device of a medical tumor radiation treatment instrument. Background technique [0002] Traditional radiation therapy equipment includes central processing control device, treatment bed, treatment host, power supply and signal transmission device, electric cabinet control device, etc. Among them, the treatment host includes a drum, which is equipped with an X-ray generating device for helical tomography and an image acquisition and receiving device, as well as a radiation source, a grating and a collimator device for radiation therapy, as well as a device for detecting the effect of radiation therapy and Dose detection device for radiotherapy progress, etc. [0003] Among them, the radiation source device, the grating and the collimator device are key components, which are related to the overall structural arrangement of the radiation therapy instrument and the effect and effi...

Problems solved by technology

[0005] However, the motorized multi-leaf collimator is composed of many independent tungsten alloy sheets and micro-motors overlapping together. First of all, it is limited by its structure and size, and the field of view cannot be exactly consistent with the shape of the tumor. The conformal field is obviously very rough. ;In addition, the thin slices need to move flexibly, therefore, the blades cannot be too close together, which will inevitably cause the leakage of rays through the gap between the blades, which greatly reduces the performance and quality of the intensity-modulated conformal field; Third, the tungsten alloy blade is driven by a stepping motor, and it takes time to move. In the image-guided intensity modulation conformal, it is impossible to adopt a more advanced way of beam following the movement of the organ. Only the treatment bed following technology can be used. The corresponding following speed will be affected

[0006] As mentioned above, the use of multiple radiation sources and multiple sets of multi-leaf grating collimator devices will make the structure of the radiotherapy equipment complex, and its image follow-up rate is low, making the treatment efficiency poor; and the safety of radiotherapy is not high, and the treatment effect is poor
