Problems solved by technology

[0004] The shortcomings of current radiotherapy positioning include: (1) There is a fixed gap between the low-temperature thermoplastic film and the bottom plate; (2) The stretchability of the low-temperature thermoplastic film is difficult to control; (3) The locking is prone to fall off during the fixation process, and the fixation fails; ( 4) The skin pinching injury accident caused by the fixing process; (5) The fixing accessories are designed in separate parts, which are easy to lose; (6) The mechanical structure of the fixing lock is directly stressed; (7) The limitation of the limbs is missing; (8) The operation is laborious , time-consuming and cumbersome

Embodiment 1

[0021] Example 1 Body Positioning Hollow Fixing Frame for Body Fixation with Elastic Tongue for Radiation Therapy

[0022] refer to figure 1 , Image 6 , The body positioning hollow fixing frame of the fixed tongue limb fixed radiotherapy body of the present invention is composed of two parts: a "fixed tongue limb fixed frame" and a "mortise and tenon limb fixed body membrane".

[0023] refer to figure 1 , "Tongue Limb Fixation Fixture" The fixed groove wall 19, the pressure plate 24, the fixed bottom plate 25, the pressure plate shaft 26, the pressure plate positioning recess 33, the bottom plate slope 34, the treatment groove 35, the bottom plate positioning hole 37, the bottom plate hollow part 38, the bottom plate composite positioning hole 39, 10 mortise and tenon joints Type pressing plate structure 102, expansion bolt hole structure 105 and 8 spring tongue pressing plate structures 107 are formed. The main structure of the fixing frame is a rectangular fixed bo...

Embodiment 2

[0028] Example 2 Method of use of the present invention

[0029] When in use: the "mortise and tenon limb fixed fixation frame" is placed on the treatment bed (or positioning bed), and the relative position is moved so that the bottom plate positioning hole 37 on the fixed frame and the bottom plate composite positioning hole match the corresponding design on the bed, and the "frame" is completed. bed positioning". The patient lies flat in the "U"-shaped treatment tank 35, and two operating technicians work together to immerse the mortise-and-tenon limb-fixed body membrane into a constant temperature water tank at 60-70 degrees Celsius. The bead handle 5 covers the part that needs to be fixed and positioned, and the softened low-temperature thermoplastic sheet 1 is stretched through the relative fixed bead 2, and the fixed mortise 3 is put in place in the fixed tenon 20 on the fixed frame, and the expansion bolt structure 101 The upper expansion flap 10 is inserted into th...

Abstract

The invention provides an elastic tongue limb fixing type radiation treatment body part positioning hollow fixing frame which is composed of two parts of an elastic tongue limb fixing type fixing frame and a tenon-and-mortise limb fixing type body membrane. The elastic tongue limb fixing type radiation treatment body part positioning hollow fixing frame is mainly applied to conformal external contour position limiting and fixing of the inferior belly part of a patient. The principle of dual locking of a tenon-and-mortise structure and an elastic tongue buckling lock and the design of an integrated membrane strip and a hollow bottom plate are adopted so that accurate positioning can be achieved, operation is enabled to be more convenient and dose is enabled to be more accurate, the fixing bottom plate and a treatment couch are enabled to be integrally connected and error rate can be reduced. The design of the cross stress structure of the elastic tongue structure and a pressing plate is scientific so that loosing in the application period and an event of damage to the human body can be avoided. All shortcomings and defects in existing radiation treatment positioning structures can be effectively solved. The elastic tongue limb fixing type radiation treatment body part positioning hollow fixing frame is reasonable in design, convenient and safe to operate, environment-friendly, obvious in the fixing effect and relatively high in practicality and generality.

Description

technical field [0001] The invention belongs to the technical field of radiotherapy positioning, and relates to a radiotherapy body positioning hollow fixing frame for fixing limbs with a spring tongue. It is a radiotherapy positioning and fixing device, especially for the positioning and fixing of the lower abdomen of the human body. It is an important tool for precise positioning and implementation in radiotherapy. Background technique [0002] Low-temperature thermoplastic sheet is a new type of medical material processed by a series of physical and chemical methods, which is specially synthesized polymer polyester. It is used for orthopedic external fixation, orthotics, and braces. Because the material has outstanding properties such as non-absorbing radiation, good shaping effect after heating and softening, and unique shape memory function (when the shaping is not satisfactory, it can be reheated, reshaped or partially heated and reshaped), etc., As well as simple ope...
