Description
Technical field
This utility model belongs to radiotherapy locating device technical field, relate to a kind of radiotherapy location fixed mount accessory column type locking structure, be on radiotherapy positioning equipment a kind of play fix, accessory that locking (anti-slip) acts on, be the important component part 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 of current radiotherapy localization: (1) Low Temperature Thermal plastic film and base plate there is fixed interval (FI); (2) easily there is locking and come off in fixation procedure, fixes unsuccessfully; (3) fixation procedure causes skin to squeeze folder injury accident; (4) standing finish split design, easily loses; (5) fixing locking mechanical structure is directly stressed; (6) use operation effort, loaded down with trivial details.
Based on above deficiency and drawback, we devise a radiotherapy localization fixture.
Summary of the invention
The purpose of this utility model solves conventional radiotheraphy location drawback, and providing a kind of radiotherapy to locate fixed mount accessory column type locking structure, is the accessory played a crucial role in a kind of accurate radiotherapy location.This utility model adopts the principle of joinery and its construction, off-centre operation locking structure, fixing spacing for related film bar, coordinates special fixed body frame, reaches accurate location.
This utility model by fixing cell wall, fixing tenon, fixed base plate, tenon stricture of vagina, compress stricture of vagina, cylinder briquetting, joint pin, cylinder axis, cylindrical base, cylinder spanner and cylinder and leave a blank and jointly form.Fixing cell wall is the edge of sphenoid perpendicular to fixed base plate of a upper-thin-lower-thick; Another marginal center of fixed base plate 25 is connected with cylindrical base, one end dissociative and centre are run through cylinder axis, the two ends of axle are respectively connected with mobilizable cylinder briquetting, be connected with the cylinder spanner of outer rim is static by joint pin between two cylinder briquettings, centre is left cylinder and is left a blank, the fixing tenon that corresponding with it is on fixing cell wall, fixing tenon has multi-turn tenon stricture of vagina, and the outer of cylinder briquetting is designed with compression stricture of vagina with fixing cell wall near place.
This utility model is the accessory structure that fixed system is accurately located in radiotherapy.He can realize being in the isostructural limitation locking of film bar in fixing tenon 20 completely, coordinates special positioning rack series to reach or close to zero shift; The design of fixing cell wall 19 can be avoided squeezing the skin damage events such as folder and occur; The intersection force structure design science of cylinder locking structure and film bar, without the need to worrying fixing the getting loose between the operating period; Simplify, a step locking, can make the operation of technician more simplify with convenient.Efficiently solve all drawbacks and the deficiency of the existence of current radiotherapy localization structure.This utility model is reasonable in design, easy to operate, safety, environmental protection, and fixed effect is obvious, and practicality and versatility are all stronger.

Detailed description of the invention
This utility model is further described by reference to the accompanying drawings.
Embodiment 1 radiotherapy location fixed mount accessory column type locking structure
See figures.1.and.2, this utility model by fixing cell wall 19, fixing tenon 20, fixed base plate 25, tenon stricture of vagina 27, compress stricture of vagina 57, cylinder briquetting 58, joint pin 59, cylinder axis 60, cylindrical base 61, cylinder spanner 62 and cylinder and leave a blank and 63 to form.Fixing cell wall 19 is the sphenoid of a upper-thin-lower-thick, and it is vertically connected at an edge of fixed base plate 25, and the configuration of fixing cell wall 19 wedge body makes the curved-surface structure that can better attach and be suitable for human body.Another marginal center of fixed base plate 25 is connected with cylindrical base 61, and one end dissociative and centre are run through cylinder axis 60, and the two ends of cylinder axis 60 are respectively connected with mobilizable cylinder briquetting 58, can along pressing plate shaft axial rotation; Be connected with the cylinder spanner 62 of outer rim is static by joint pin 59 between two cylinder briquettings 58, centre is left cylinder and is left a blank 63, the fixing tenon 20 that corresponding with it is on fixing cell wall 19, fixing tenon 20 is designed to the end and slightly pushes up thin circular cone structure, realize linearly fastening, fixing tenon 20 surface distributed has the tenon stricture of vagina 27 of a circle circle, can increase the frictional force between the film fourth of the twelve Earthly Branches 3 and fixing tenon 20.The outer of cylinder briquetting 58 and fixing cell wall 19 are designed with near place and compress stricture of vagina 57, for increasing the frictional force between cylinder briquetting 58 and film bar etc., and fastening locking effect.
Embodiment 2: using method:
The first step: first locking.By needing fixing object structure to be inserted in fixing tenon 20, because thin circular cone structure is slightly pushed up at fixing tenon 20 end, can make to combine both are linearly fastening, multi-turn tenon stricture of vagina 27 structure can keep fixation clip static, and first locking completes.
Bis-Walk: second locking.Cylinder briquetting 58 is upwards rotated by cylinder axis 60, and compress stricture of vagina 57 and contact with each other and locking with film bar (fixed object), object structure will be stopped by cylinder briquetting 58 and be locked in wherein.Compress stricture of vagina 57 pairs of film bars generation pressure owing to forcing due to the bias design of cylinder briquetting 58, be then finally fastened and fixed, second locking completes.
