Description

Prostrate type body fixing frame

Technical Field

The utility model relates to a prostrate formula somatic part mount for fix patient's somatic part at tumour radiotherapy in-process, belong to radiotherapy's auxiliary assembly.

Background

When tumor patients are accurately treated by radiotherapy for many times, the focus parts of the patients need to be irradiated at the same position every time so as to ensure the treatment effect. The corresponding part of the patient is fixed according to the requirements of different tumor positions of the patient, and can be repeatedly reset to the same position during the treatment. In the current positioning mode, the positioning film is increasingly becoming the first choice of positioning products in the radiotherapy industry due to the advantages of convenience and rapidness in use, good repeatability and the like.

The positioning film is matched with the fixing frame to fix the patient on the treatment bed. At present, the types of the fixing frames which can be used for the prone position radiotherapy in the market are less, and most fixing frames mainly adopt flat plates. The flat plate type fixing frame lacks humanized support for a human body curve, and patients are difficult to completely align when repeatedly aligning, so that aligning errors are easy to generate. For this reason, improvement of the structure of the fixing frame is required.

For example, in the chinese utility model with publication number CN203898945U, a prone position body membrane fixing radiotherapy device is provided, which comprises a web fixing bottom plate and a bolster fixing bottom plate, wherein the web fixing bottom plate and the bolster fixing bottom plate are connected by adopting a notch and a convex connecting plate, and a web is arranged on the web fixing bottom plate, the web is made of carbon fiber material, a U-shaped abdominal hole is arranged on the web, and two grooves matched with thighs of a patient are arranged at the lower part of the web, so that the patient can conveniently place two legs; the movable bolster supporting plate is arranged on the bolster fixing base plate and can slide along the direction of the bolster fixing base plate, a bolster frame with T-shaped air holes is arranged on the movable bolster supporting plate, a bolster made of sponge materials is arranged on the bolster frame, and the air holes are 7.5cm multiplied by 10.5cm and are convenient for ventilation of patients during breathing. According to the prone position body membrane fixing radiotherapy device, the abdominal hole is formed in the web plate, so that the abdomen of a patient is placed in the abdominal hole, the intestine sags and is fixed, the distance between the abdomen and the target area is effectively increased, and the purpose of protecting normal tissues is achieved; the pillow can be fixed to the pillow of portable armful of setting of pillow layer board and prevent long-time pressurized deformation, again with the position relatively fixed of web bottom plate, the repeatability of pendulum position when having guaranteed patient prone position. However, the prone position abdomen body membrane fixing radiotherapy device also belongs to a flat plate type fixing frame, the human body curve is lack of humanized support, and the segmented fixing device, the throw pillow type prone position mode and the plug block type body membrane fixing mode have large repeated influence on the repeated position arrangement of a patient, and easily generate position arrangement errors.

As shown in fig. 6 and 7, the small belly frame 9 includes a horizontally disposed outer rim 41, a concave belly support surface 42, and a bottom hollow 43 with a vertical rim 45. The small-sized abdomen frame 9 may be combined inside the abdomen frame 2. The outer dimensions of the outer frame 41 are the same as those of the horizontal frame 21, and the small-sized abdomen frame 9 can be combined inside the abdomen frame 2. When the small-sized abdominal frame 9 is assembled inside the abdominal frame 2, the outer rim 41 of the small-sized abdominal frame 9 coincides with the horizontal rim 21 of the abdominal frame 2. A plurality of fixing holes 44 corresponding to the fixing holes 24 are provided on the horizontal frame 41, and the small-sized abdomen frame 9 and the abdomen frame 2 are fixed by the fixing holes 24 and 44 and fixing members such as fixing pins or screws. At this time, the abdomen supporting surface 42 of the small-sized abdomen frame 9 is positioned above the abdomen supporting surface 22 of the abdomen frame 2, and the abdomen supporting surface 42 of the small-sized abdomen frame 9 is closer to the upper surface of the mount body 10 than the abdomen supporting surface 32; thus, the abdominal support surface 42 of the small abdominal frame 9 is used to support a smaller abdomen, fitting a thinner patient, relative to the abdominal frame 2 and the medium abdominal frame 8.

As can be seen from fig. 1, 4 and 6, in the prone body fixing frame, the fixing frame body 10 has a large-size abdominal frame 2, the medium-size abdominal frame 8 and the small-size abdominal frame 9 can be combined with the abdominal frame 2, and the medium-size abdominal frame 8 or the small-size abdominal frame 9 are combined inside the abdominal frame 2, so that the prone body fixing frame can adapt to patients of different sizes, does not squeeze the abdomen of the patient, and can provide proper support for the abdomen.

In this embodiment, only three abdomen frames with a large size, a medium size and a small size are taken as an example to describe the support of the prone body part fixing frame on the abdomen of different patients, in practical use, the number of the auxiliary abdomen frames is not limited to two, and may be more or less, but at least one auxiliary abdomen frame should be matched with the fixing frame body 10. The plurality of abdominal frames have abdominal support surfaces of different heights, respectively, and the horizontal rim of each abdominal frame has the same size as the horizontal rim 21 of the abdominal frame 2 for overlapping and fixing with the horizontal rim 21 of the abdominal frame 2.

The peritoneum fixing mode of the prostrate body fixing frame provided by the utility model is introduced below. The utility model provides a prostrate formula somatic part mount and peritoneum cooperation realize the fixed of patient's somatic part. At least two groups of film locking mechanisms are respectively arranged on two sides of the fixing frame body 10, each group of film locking mechanism comprises a slide rail fixed on the side surface of the fixing frame body 10 and a buckle capable of moving on the slide rail, and a plurality of positioning holes for fixing the peritoneum are arranged on each slide rail.
