Description

Oropharyngeal tumor radiotherapy fixation device

technical field

The utility model relates to the field of medical equipment, in particular to a radiotherapy fixation device for oropharyngeal tumors.

Background technique

Currently, the most effective treatment for oropharyngeal tumors is surgical resection and radiotherapy, among which radiotherapy is the most basic treatment for oropharyngeal tumors. The general practice of radiotherapy is to design the irradiation field through simulator positioning or taking positioning X-ray films, and perform radiotherapy according to the designed irradiation field, which can effectively eliminate lesions and minimize accidental injury to non-lesional areas. Due to the location of the tumor in the throat, during radiotherapy, the patient lies in the treatment room with his mouth open, and the radiation passes through the mouth to the radiation field. In actual situations, if the patient keeps opening his mouth, he cannot keep the same posture all the time, the size of the mouth opening will change, and the tongue will move wildly, which will affect the irradiation of radiation, affect the treatment effect, and the radiation will accidentally injure the tongue during the treatment. In the prior art, generally adopt a tongue depressor bottle, allow the patient to be contained in the mouth, to keep the size of opening and keep the tongue position fixed. Existing defect is: because the course of treatment of radiotherapy is more than one, and the design radiation field of each course of treatment is all the same, the depth and the position etc. that the patient puts the tongue depressor bottle in the mouth each time are not the same, cause the size of the patient's mouth opening to be different every time during treatment. As a result, the curative effect of radiotherapy is affected, and the patient's tongue is accidentally injured.

Utility model content

In order to solve the problem that the size of the patient's mouth is not the same each time, the utility model provides a radiotherapy fixation device for oropharyngeal tumors.

The technical solution is: a radiotherapy fixation device for oropharyngeal tumors, including a fixed body and a hand-held body, the hand-held body is connected to one end of the fixed body, and the hand-held body is provided with a recessed hand-held part, which is convenient for users Hold the fixing device by hand; the fixing body is a hollow cylinder without a bottom surface, the surface of the fixing body is marked with a scale along the direction of the bottom surface, the position of the scale is provided with a groove, the fixing body is covered with a fixing ring, and the inner side of the fixing ring is provided with The protrusion that matches the groove of the scale position, the fixed ring can engage with the groove of the scale position on the surface of the fixed body through the protrusion on the fixed ring, the fixed ring is engaged on the fixed body, and the fixed ring is used to limit the fixed body Depth placed in the user's mouth.

A level is also provided on the fixed body, and the level is used to measure the inclination of the fixed body placed on the user's mouth.

Further, the level is a digital display electronic level, and the user can conveniently read the reading of the level and adjust the angle of the fixed body at any time.

Further, the material of the fixed body and the hand-held body is made of plastic, and the plastic material is relatively light, and will not make the user feel comfortable because it is too heavy when placed in the mouth.

Further, the material of the fixing ring is made of silica gel, which has certain elasticity, so the fixing ring can be manually moved to each scale position.

Beneficial effects: the oropharyngeal tumor radiotherapy fixation device provided by the utility model has simple structure, low manufacturing cost and convenient use; it is used as an auxiliary tool during radiotherapy, which can ensure that patients can easily and conveniently put the fixation device into the mouth each time The depth and angle of the radiotherapy are consistent, so that the effect of radiotherapy is better, and the accidental injury of radiotherapy to the non-lesional area can be minimized to the greatest extent.

detailed description

A radiotherapy fixation device for oropharyngeal tumors, comprising a fixed body and a hand-held body, the hand-held body is connected to one end of the fixed body, and the hand-held body is provided with a recessed hand-held part, which is convenient for the user to hold and fix device; the fixed body is a hollow cylinder without a bottom surface, the surface of the fixed body is marked with a scale along the direction of the bottom surface, the position of the scale is provided with a groove, the fixed body is covered with a fixed ring, and the inside of the fixed ring is provided with a concave groove corresponding to the position of the scale. The groove matches the protrusion, and the fixing ring can engage with the groove on the surface of the fixed body through the protrusion on the fixing ring. mouth depth.

A level is also provided on the fixed body, and the level is used to measure the inclination of the fixed body placed on the user's mouth.

The level is a digital display electronic level, and the user can conveniently read the reading of the level and adjust the angle of the fixed body at any time.

The materials of the fixed body and the hand-held body are made of plastic, and the plastic material is relatively light, so it will not make the user feel comfortable because it is too heavy when placed in the mouth.

The material of the fixing ring is silica gel, which has certain elasticity, so the fixing ring can be manually moved to each scale position.

When the patient uses the oropharyngeal tumor radiotherapy fixation device for the first time, manually adjust the fixation ring to a certain scale position until the fixation body is placed in the mouth to maintain a more comfortable state, and read the value on the level.

In the subsequent use, the patient will adjust the fixing ring to the scale position used for the first time, and also adjust the horizontal direction to the value displayed by the level meter for the first time.
