For the purpose of diagnosis, prevention, monitoring, treatment, or amelioration of a disease; diagnosis, monitoring, treatment, mitigation, or functional compensation of injury; examination, replacement, regulation or support of a physiological structure or physiological process; support or maintenance of life; controlling pregnancy; by examining a sample from a human body, information is provided for medical or diagnostic purposes.

Since some anatomical structures are not easily identified on CT images, special markers are needed for radiotherapy localization of some tumor patients, such as: some patients with rectal cancer, anal canal cancer, etc. need to mark the anus. It is clinically desirable to place markers at these sites that can be visualized on the CT image so that the anatomy is easily identified on the localized CT. At present, the clinical multipurpose lead wire is enclosed into a ring shape and is stuck to the anus for marking, because the lead wire is metal, metal artifacts are easily generated during CT imaging, the judgment of doctors is influenced, and the lead wire ring can not be reused, so that the waste of metal materials is caused.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a punctiform mark structure for tumour radiotherapy has solved and has enclosed into cyclic annular subsides with the lead wire and mark in anus department, because it is the metal, produces the metal artifact easily when CT formation of image, influences the doctor and judges and can not used repeatedly's problem.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a punctiform mark structure for tumour radiotherapy, includes development pearl and glues the subsides, the development pearl is pasted in needs mark department through gluing the subsides, the development pearl includes the plastic casing, the inside packing of plastic casing has the contrast medium, the plastic casing openly is circular, and the side is arc, the back of plastic casing is the plane of pasting with gluing, and the plane sets up to the frosting.

Preferably, the adhesive tape is a common medical transparent adhesive tape, and can be cut according to the specific condition of a patient.

Preferably, the flat surface portion of the developing bead is a portion having a largest diameter, and the developing bead is attached to a center of the sticker.

Preferably, the center of the bottom plane of the plastic shell is provided with an inner concave surface, and a fine line is bonded inside the inner concave surface through hot melt adhesive.

Preferably, the hot melt adhesive does not protrude beyond the plane of the bottom of the plastic housing.

Preferably, the contrast agent is one of an iodine contrast agent or a barium contrast agent.

Advantageous effects

The utility model provides a punctiform mark structure for tumor radiotherapy. Compared with the prior art, the method has the following beneficial effects:

(1) the point-shaped marking structure for tumor radiotherapy can be used for tumor radiotherapy CT positioning marking by sticking the developing beads to the anus and other positions of a patient by using a glue sticker, is low in counterfeiting cost compared with the existing lead wire ring marking, is disposable and is more sanitary; the CT imaging system has no metal component, and no metal artifact during CT imaging; in addition, the used materials are all mature medical materials, so the material is very safe.

(2) This punctiform mark structure for tumour radiotherapy sets up to dull polish plane through developing the pearl bottom surface, and is more firm when pasting with gluing, can avoid tearing down gluing after the radiography finishes, and the developing pearl is unexpected to drop and in the abrupt anus, leads to the later stage to be difficult to the problem of taking out.

(3) This point-like mark structure for tumor radiotherapy through a fine rule that bonds in developing pearl bottom, it can paste together along with developing the pearl and paste on the gluey subsides, also takes developing the pearl out more easily when tearing off the gluey subsides to prevent that developing the pearl accident from droing and getting into in the anus.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, 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.

Referring to fig. 1-4, the present invention provides a technical solution: a spot-shaped marking structure for tumor radiotherapy comprises a developing bead 1 and a glue paste 2, wherein the glue paste 2 is a common medical transparent glue paste and can be cut according to the specific situation of a patient, the developing bead 1 is pasted on an affected part through the glue paste 2, the developing bead 1 comprises a plastic shell 11, the plastic shell 11 is made of plastic with hardness similar to that of a fish oil capsule shell, the plastic shell 11 is filled with a contrast agent 12, the contrast agent 12 is one of an iodine contrast agent or a barium contrast agent or a diluent thereof, the developing bead 1 is pasted on the anus of the patient and other positions needing to be marked by using the glue paste 2, the spot-shaped marking structure can be used for tumor radiotherapy CT positioning, and compared with the existing lead wire ring developing, the spot-shaped marking structure is low in counterfeiting cost, disposable and more sanitary; the CT imaging system has no metal component, and no metal artifact during CT imaging; in addition, the used materials are all mature medical materials, so the material is very safe; the front surface of the plastic shell 11 is circular, the side surface of the plastic shell is arc-shaped, the back surface of the plastic shell 11 is a plane adhered with the adhesive sticker 2, the plane is set to be a frosted surface 13, the plane part of the developing bead 1 is the part with the largest diameter, and the developing bead 1 is adhered at the center of the adhesive sticker 2. Through setting up 1 bottom surface of developing pearl into dull polish plane, it is more firm when pasting with gluing 2, can avoid tearing down gluing 2 after the radiography finishes, developing pearl 1 accident drops and gets into in the anus.
