Abstract

The invention discloses a mobile positioning body frame applied in hospitals, and aims to provide a positioning body frame consisting of a chassis 1, a longitudinal moving device 2, a lifting device 3 and a transverse positioning device 4. The invention is realized by the following technical proposal: the chassis 1 consists of a body position plate 6 and a slide way body 8 which are embedded and placed in a bottom frame 7and fixed by internal threads; a slide way 9 and a slide block 10 are glidingly assembled; the slide block 10 and an outer tube bottom plate 16 are connected and fixed by screw threads; the longitudinal corresponding lifting device 3 is connected by a bridge plate 24 and fixed by a screw cap; the bridge plate 24 is provided with a positioning mark pen 5 to form a positioning frame 26; in order to increase positioning operation range, three groups of positioning frames are arranged; scales are arranged in the longitudinal direction, the height direction and the width direction; and the body position plate 6 is provided with a body position base so as to achieve three-dimensional positioning. The mobile positioning body frame has the characteristics of simplicity and convenience, economy, high accuracy and good repeatability, and is applied to precise radiotherapy for tumor patients in the hospitals.

Description

Mobile positioning rack

Technical field

The mobile positioning rack of 1 step of the present invention and a kind of clinical practice.

Background technology

The location of human body patient part, it is the problem that domestic and foreign hospitals research is concerned about always, existing all kinds of positioning rack and body film be applied in clinical in, but also be in and constantly improve process, the purpose of accurate treatment, require tumor kitchen range district to obtain the irradiation of maximal dose and normal surrounding tissue or organ are subjected to less or avoid radiation, accurately the location is the important step of accurate treatment, the positioning rack of a kind of easy, economy of present clinical accurate treatment job demand, accuracy height, good reproducibility.

Summary of the invention

The deficiency that the objective of the invention is to overcome prior art designs, and finishes by following conception plans.

Mobile positioning rack: constitute by chassis 1, longitudinal moving device 2, lowering or hoisting gear 3, horizontal positioning device 4.

Details are as follows to this positioning rack:

Chassis 1 is made up of position plate 6, slipway 8, underframe 7, and longitudinal moving device 2 is made up of slipway 8, slide block 10, vertical scale 11.Lowering or hoisting gear 3 is made up of outer tube 12, interior bar 13, position-limiting tube mother 14, clamper 21, altitude scale 15.
