Abstract

The utility model discloses a fixing device for head radiotherapy. In the device, a headrest, the center of which is provided with a groove, is arranged on a base plate, and two sides of the headrest are provided with a hollow lower support and an upper support that can slides up and down inside the lower support. When sliding to a proper position, the upper support can be fixed by a screw nut at a side surface of the lower support. A threaded through hole is arranged at an upper end of the upper support, the threaded through hole is provided with a screw used for cooperating with the same inside, an outside end surface of the screw is provided with a rotatory handle, and an inside end surface of the screw is provided with a protection pad. In radiotherapy, position of the upper support and that of the screw is adjusted to fix the head according to the need of a patient, and then radiotherapy can be performed. The device has the advantages of simple structure and convenient operation. The device can fix the head in radiotherapy process, without causing discomfort.

Description

Head radiotherapy fixture

Technical field

This utility model relates to technical field of medical instruments, relates in particular to a kind of head radiotherapy fixture.

Background technology

In the modern radiotherapy technology, when the tumor of head is carried out radiotherapy, need accurate positioning, general line drawing method location of adopting is inaccurate, trickle rocking takes place in patient's head easily, cause radiotherapeutic effect bad, also the health to patient has caused unnecessary harm, and the method that also has is that the head with patient is fixed in the mould, carries out radiotherapy then, though this method is patient's head fixedly, it is not shaken, but this method complicated operation, it is narrow to be fit to face, and patient's head places mould, feels very uncomfortable.

The utility model content

Technical problem to be solved in the utility model is: a kind of head radiotherapy fixture is provided, and this apparatus structure is simple, easy to operate, can realize the fixing of human body head in the radiotherapy process, and patient is felt under the weather.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of head radiotherapy fixture, comprise base and headrest, and described headrest is fixed on the described base, and its middle part has the groove that can supply human body head to put into; Described head radiotherapy fixture also comprises lower carriage, and described lower carriage is hollow structure and the two ends of being fixed in described headrest, and the described lower carriage outside is provided with and screws nut; Upper bracket, described upper bracket slides and is arranged in the described lower carriage, and its top is provided with the tapped through hole of a horizontal direction; Screw rod, described screw rod passes described tapped through hole, and its inboard is fixed with the protective pad that directly contacts with human body head.

As a preferred implementation, be fixed with rotating handles on the end face of the described screw rod outside.

Owing to adopted technique scheme, the beneficial effects of the utility model are: have the groove that can supply human body head to put at described headrest middle part, then patient can not feel well when accepting, be provided with lower carriage in the headrest both sides in addition, and upper bracket is to be arranged at versatilely in the lower carriage, therefore can adjust the position of upper bracket according to different patients' needs, control the position of the protective pad that directly contacts with human body simultaneously, head position in the time of can accurately controlling patient's radiotherapy, avoided human body is caused unnecessary damages, also improved the effect of radiotherapy.
