Description

Play tongue limbs fixed radiotherapy body location hollow fixed mount

Technical field

This utility model relates to radiotherapy field of locating technology, relates to a kind of fixed radiotherapy body of tongue limbs that plays and locates hollow fixed mount.Being a kind of radiotherapy device for positioning and securing system, fixing especially for the underbelly location of human body, is the important tool of accurately locating in radiotherapy, implementing.

Background technology

low temperature thermo-plastic plankinga kind of macromolecule polyester of special synthesis, through the novel medical material of series of physical and chemical method process, for the making material of orthopaedics extenal fixation, orthosis, brace.Due to this material have do not absorb ray, thermoplastic after there is the outstanding properties such as good plastotype effect and specific shape memory function (when plastotype is unsatisfied with can post bake, again plastotype or local heat shape again), and simple to operate, convenient fixing, be optimal external fixation system in current radiotherapy localization.

Current, in our radiotherapy, the fixing low temperature of the employing mostly thermo-plastic planking of patient combines the object that the fixing mode of machinery reaches location.The requirement of radiocurable location: top to bottom, left and right, front and rear three-dimensional requires accurately fixing, displacement error <6MM.The body such as breast, abdomen fixes departure difficulty, and heart beating, the breathing and enterokinesia etc. of patient affect locating effect.Although mechanical means is various on the market, practical effect detects and finds mostly there is displacement error.

The deficiency that current radiotherapy localization exists has: (1) Low Temperature Thermal plastic film and base plate there is fixed interval (FI); (2) Low Temperature Thermal plastic film body retractility is difficult to control; (3) easily there is locking and come off in fixation procedure, fixes unsuccessfully; (4) fixation procedure causes skin to squeeze folder injury accident; (5) standing finish split design, easily loses; (6) fixing locking mechanical structure is directly stressed; (7) the spacing fixing disappearance of limbs; (8) use operation effort, time-consuming and loaded down with trivial details.

Based on above deficiency and drawback, we devise a radiotherapy localization fixture, and the supporting dependent body film be combined with it.

Summary of the invention

The purpose of this utility model solves conventional radiotheraphy location drawback, provides a kind of radiotherapy pinpoint device---play tongue limbs fixed radiotherapy body location hollow fixed mount.This utility model Main Function is that the conformal outline of lower abdomen position patient is spacing fixing, adopt joinery and its construction, play the principle of the dual locking of tongue padlock, one film bar and the design of hollow base plate, reach pinpoint and make more convenient to operate and dosage is more accurate simultaneously.

This utility model bullet tongue limbs fixed radiotherapy body location hollow fixed mount is by playing the fixed fixed mount of tongue limbs and Tenon limbs fixed body film two parts form.
