Abstract
The utility model relates to an adjustable oral cavity expander, which is mainly used for radiation therapy of nasopharyngeal darcinoma and esophageal cancer. A body of the oral cavity expander is a hollow body with an opening; at least three groups of bulged positioning lines are arranged on the outer surface of the body; and a support beam (which is also can be used as a handle) which protrudes out of an opening plane of the body is arranged in the middle of the body. During treatment, an oral cavity can be expanded according to requirements, so that sensitive organs (salivary glands or brains) are far away from a radiation field to reduce the ray dose of the sensitive organs, so that the harm degree of the sensitive organs is reduced. The adjustable oral cavity expander has a hollow structure and is provided with the support beam, and the support strength is ensured while materials are saved, so that the adjustable oral cavity expander is not deformed in the using process.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to a kind of apparatus that the oral cavity is used of expanding, and belongs to International Classification of Patents A61M technical field.
Background technology
In the radiation therapy process of the nasopharyngeal carcinoma and the esophageal carcinoma, need constantly to expand repeatedly the oral cavity.Because the position is more special, the one, the doctor operates and has any problem, and patient is difficult for partner treatment.The 2nd, in the middle of each therapeutic process, be difficult for realizing accurately location, influence relates to benign tissue on every side easily.
Summary of the invention
The purpose of this utility model is to provide a kind of and reduces responsive organ extent of injury on every side, guarantees support degree, indeformable scalable oral cavity expander.
The purpose of this utility model realizes through following technical scheme.
A kind of scalable oral cavity expander, its body is open ducted body, on this external surface, is provided with three groups of protruding position lines at least.In the middle part of body, be equipped with and protrude from the uncovered planar brace summer of body.
This utility model scalable oral cavity expander can be according to patient's oral cavity size, and the expansion oral cavity is regulated.When radiotherapy, can make responsive organ away from diapason, reduce the ray amount of receiving to alleviate.Simultaneously, expander has been taked hollow structure in the oral cavity, and brace summer is arranged.In economical with materials, guarantee support degree, indeformable in the use.
Description of drawings
Fig. 1 is the schematic perspective view that this utility model can demonstrate internal structure;
Fig. 2 is the schematic perspective view that this utility model can show outer surface.
Among the figure: 1, ducted body, 2, brace summer, 3, position line.
The specific embodiment
Referring to Fig. 1, Fig. 2, the scalable oral cavity expander of this utility model is used in the radiotherapy of the nasopharyngeal carcinoma and the esophageal carcinoma.The body of oral cavity expander is open ducted body 1, enables to reach the accurate location of irradiation at the position line 3 that is provided with the convexity of proportional spacing more than three groups on the outer surface of ducted body (being three groups in illustrated embodiment).The middle of ducted body 1 is equipped with and is protruded from uncovered planar brace summer (but the double as handle is used).2, to guarantee support degree, can not be out of shape.During treatment, the oral cavity expander is placed in the oral cavity, according to the difference of patient's mouth size, bite corresponding position line with tooth, so that the oral cavity is expanded, degrees of expansion is accurate, makes responsive organ wild away from ray, reduces the ray amount of receiving to alleviate.The design of position line, not only simple but also have a repeatability of height.Satisfy the demand of oral cavity size different patient oral cavity expansion.But the hollow structure of oral cavity expander design is also economical with materials the time.
Claims (2)
1. a scalable oral cavity expander comprises body (1), it is characterized in that: described body (1) is open ducted body, is provided with the position line (3) of at least three groups convexity at the outer surface of body (1).
2. scalable according to claim 1 oral cavity expander is characterized in that: be equipped with in the centre of said body (1) and protrude from the uncovered plane of body, and the brace summer (2) can the double as handle used.
