Description
Technical Field
The utility model belongs to the field of medical equipment, concretely relates to tissue compensation membrane.
Background
IMRT (Intensity-modulated radiation therapy) is an advanced high-precision radiation therapy that utilizes a computer-controlled X-ray accelerator to deliver a precise dose of radiation to a malignant tumor or a specific region within a tumor. IMRT can adjust (or control) the intensity of radiation to more accurately dose the radiation according to the 3D shape of the tumor, and can also apply higher doses of radiation by focusing on areas within the tumor while surrounding normal tissue receives the minimum dose.
However, due to the deep dose distribution characteristics of different energy rays, the surface dose decreases with increasing ray energy, so that a tissue compensation film is required to increase the dose of a tumor superficial target area during clinical radiotherapy.
The traditional tissue compensation film has no individualized characteristic, the traditional compensation film with uniform thickness can not play a compensation role, for example, the lung wall compensation film of a breast cancer patient needs to be thicker, and the traditional tissue compensation film is not well attached to the curved surface body surface of the patient, so that air gaps are caused, and uncertainty exists between the actually received dose of a superficial tumor target area and the tumor receiving amount in a planning system during actual treatment.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a tissue compensation membrane, this compensation membrane have solved traditional compensation membrane and have treated the attached not good and problem that leads to air gap in compensation area surface, and attached human skin that can be fine can not produce air gap, also can not the landing.
In order to achieve the above object, the present invention provides a tissue compensation film, comprising: the stereoplasm epitheca, its lower surface is equipped with: the inner wall of the bottom of the filling groove is in a shape consistent with the surface of the area to be compensated; and the soft silica gel layer is fixed in the filling groove, the upper surface and the lower surface of the soft silica gel layer have the same shape with the inner wall of the bottom of the filling groove, and the thickness of the soft silica gel layer is consistent with the depth of the filling groove.
Preferably, the hard upper shell is a 3D printed hard upper shell.
Preferably, the soft silica gel layer is integrally formed with the hard upper shell by pouring.
Preferably, the thickness of the soft silica gel layer is 2-3 mm.
Preferably, the hard upper shell is a hard upper shell which is made of nonmetal and printed in a 3D mode.
Preferably, the non-metal comprises: polylactic acid.
The utility model discloses a tissue compensation membrane has solved traditional compensation membrane and has treated the attached not good and problem that leads to air gap in compensation area surface, has following advantage:
(1) the tissue compensation membrane of the utility model has the advantages that the soft silica gel layer has the same shape with the surface of the area to be compensated, so that the soft silica gel layer has good fitting degree with the surface of the area to be compensated, meanwhile, because of the adhesiveness of the silica gel and the human skin, the human skin can be well attached without generating air gaps and slipping off, and the silica gel is not easy to adhere dust and is easy to clean;
(2) the tissue compensation membrane of the utility model is provided with a filling groove with the shape consistent with the surface of the area to be compensated through the lower surface of the hard upper shell, and soft silica gel is filled in the filling groove to support the soft silica gel, thereby ensuring the shape of the soft silica gel layer;
(3) the utility model discloses a tissue compensation membrane is equipped with and treats the filling groove of the unanimous shape of compensation zone surface through stereoplasm epitheca lower surface, according to the demand of patient itself, can design the upper surface of stereoplasm epitheca into the shape different with the lower surface as required, make the thickness of stereoplasm epitheca differ, through some clinical verification, this stereoplasm epitheca more does benefit to the radiotherapy dose that improves the skin surface than the tissue compensation colloid of traditional thickness homogeneity, reduce the organ dose that deep tissue needs the protection, the radiotherapy effect has been improved.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
A tissue compensation membrane, as shown in FIG. 1, is a structural schematic diagram of the tissue compensation membrane of the present invention, the tissue compensation membrane comprises: the hard upper shell 1 is provided with: the inner wall of the bottom of the filling groove is in a shape consistent with the surface of the area to be compensated; and the soft silica gel layer 2 is fixed in the filling groove, the upper surface and the lower surface of the soft silica gel layer have the same shape with the inner wall of the bottom of the filling groove, and the thickness of the soft silica gel layer is the same as the depth of the filling groove.
According to the utility model discloses an embodiment, stereoplasm epitheca 1 is the stereoplasm epitheca that 3D printed.
According to the utility model discloses an embodiment, soft silica gel layer 2 is through filling with 1 integrated into one piece of stereoplasm epitheca.
According to the utility model discloses an embodiment, 2 thickness on soft silica gel layer are 2~3 mm.
According to the utility model relates to an embodiment, stereoplasm epitheca that stereoplasm epitheca 1 was printed for adopting nonmetal preparation 3D.
According to the utility model discloses an embodiment, nonmetal contains: polylactic acid.
The utility model discloses a preparation and application method of tissue compensation membrane specifically as follows:
as shown in fig. 2, for the utility model discloses a preparation sketch map of tissue compensation membrane, when making, at first, rebuild patient's body surface characteristic through medical image software, select to need the compensation region, carry out the thickness design inside reverse software, soft silica gel layer 2 thickness will be got rid of to the thickness of stereoplasm epitheca 1, then slices at 3D section software, selects polylactic acid material (P L A) to carry out 3D printing shaping with the 3D printer, and 1 preparation of stereoplasm epitheca finishes.
The surface of shell 3 has the shape unanimous with the regional compensation that needs, scribbles vaseline (the drawing of patterns of being convenient for) at 3 inner walls of shell, and is fixed with stereoplasm epitheca 1 and shell 3, and the filling groove of stereoplasm epitheca 1 and shell 3 have constituted the filling chamber, adopt the mode of pouring, pour into the silica gel of having modulated, wait to pull down shell 3 after the silica gel solidification, soft silica gel 2 bonds together with stereoplasm epitheca 1 this moment, obtains the utility model discloses a tissue compensation membrane.
When using, place soft silica gel layer 2 at patient's body surface, because the adhesion of silica gel and human skin, so the human skin of attached that can be fine can not produce the air gap, also can not the landing, and the difficult adhesion dust of silica gel, easily clearance.
