A brachytherapy needle holder includes a needle card holding one or more brachytherapy needles preloaded with one or more brachytherapy seeds, wherein the needle holder includes a scored needle card shield that may be bent at the score so that the needle holder can stand up on its own, providing one-handed access.
A brachytherapy needle holder includes a needle card holding one or more brachytherapy needles preloaded with one or more brachytherapy seeds, wherein the needle holder further includes a needle card shield that provides one or more of rigidity and shielding from radiation for one or more of a physician and other medical personnel.
Cancer is one of the leading health problems and causes of mortality and morbidity in the United States and worldwide. Cancers are commonly treated using radiation therapy, which employs radiation to kill cancer cells. Prostate cancer is a serious form of cancer that affects many men, particularly as their age increases to middle age and beyond.
Brachytherapy treatment is a localized method of treating cancer in which a radiation source is placed inside or next to the area requiring treatment. An advantage of brachytherapy is that very high doses of ionizing radiation may be delivered to a localized area, such that the radiation may be supplied primarily to the area to be treated, without significantly harming tissues elsewhere in the body. This advantage, combined with a rapid reduction in radiation dose as a function of distance, may shield distant parts of the anatomy from one or more of unwanted radiation and unneeded radiation. Brachytherapy has provided excellent results for localized control of various tumors.
Brachytherapy treatment is most commonly employed to treat one or more of prostate cancer, cervical cancer, breast cancer, and skin cancer. One common example of a brachytherapy radiation source is radioactive seeds. The radioactive seeds may be deployed in needles. The radioactive seeds may be implanted in the prostate gland to kill prostate cancer cells.
To evaluate a patient's medical condition, a physician may employ tools such as one or more of ultrasound, computerized axial tomography (CAT) scans, and X-ray images in concert with dose-planning computer software programs. The physician may construct an optimal treatment plan to distribute radiation as evenly as possible throughout the affected tissue.
Proper seed placement may be important for controlling the distribution of radiation throughout the prostate gland. Placing the radioactive seeds too close together may result in a portion of the prostate receiving more radiation than is optimal. Not placing enough seeds in portions of the tissue may result in a portion of the prostate receiving less radiation than is optimal. For example, not placing enough seeds in a portion of the tissue may result in that portion of the prostate receiving an amount of radiation that may be insufficient to kill the cancer cells in that portion.
The physician may insert seeds of the same or different radioactive strengths in pre-selected locations of the tissue. The seeds may be inserted into the tissue through an implantation needle, also known as a brachytherapy needle. Multiple brachytherapy needles may be required to insert the seeds into multiple locations of the tissue. One or more of the brachytherapy needles may insert one or more seeds. An average brachytherapy session may involve the implantation of approximately eighty to one hundred seeds.
Modern medicine carries many pressures, including economic pressures, pressures relating to time demands, and otherwise. Simply put, doctors' time is very valuable, as is the time of other medical personnel, and any available product or method for reducing these time demands and increasing the efficiency with which doctors and other medical personnel can treat patients is potentially lucrative. Accordingly, products and methods that improve the efficiency with which physician and other medical personnel can treat patients may be highly valuable.
Products and methods that promote the safety of physicians and other medical personnel are also quite valuable. Given their value, physicians and other medical personnel who may be compelled to miss work due to illness may cost their employer substantial sums of money. The potential value of an invention that can promote the safety of physicians and other medical personnel may be even greater when the protection of the physicians and other medical personnel is integrated in an invention that also promotes increases efficiency of treatment.
