Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an adjustable radiotherapy fixator for male testicles. Background Art

[0002] At present, malignant tumors have become the main diseases threatening human health. Testicular malignant tumors are relatively rare tumors in the urinary system, accounting for about 5% of urogenital tumors. In recent years, the incidence of testicular tumors has also been increasing, which has also become a hidden danger affecting male health.

[0003] Radiotherapy, as the main treatment method for testicular malignant tumors, plays an important role in the treatment of testicular malignant tumors. No matter what type of testicular malignant tumor, radiotherapy is required during its comprehensive treatment process.

[0004] The first step of radiotherapy is to fix the patient's body position. At present, the latest body position fixation methods for radiotherapy include: the combination of foam glue and thermoplastic mold, the fixation method of thermoplastic mold combined with a special radiotherapy integrated carbon fiber base, the vacuum pad fixation method, etc. These new fixation methods have laid a solid foundation for accurate radiotherapy body position fixation.

[0005] However, there is currently a lack of a fixation method for accurate testicular radiotherapy. For testicular radiotherapy, according to the experience of different radiotherapy institutions, the frog position is generally adopted, with the penis attached to the abdominal wall and fixed with a negative pressure bag. However, this method has poor patient comfort and it is difficult to completely repeat the position of the testicles, so it is difficult to achieve accurate radiotherapy.

[0006] Based on the above difficulties in the simulation positioning process of testicular malignant tumor radiotherapy, the "adjustable radiotherapy fixator for male testicles" is specifically invented to increase the comfort of testicular malignant tumor patients during the treatment process, improve the repeatability of radiotherapy positioning, and thus achieve accurate radiotherapy. Content of the Utility Model

[0007] The utility model provides an adjustable radiotherapy fixator for male testicles, which has the advantages of accurate positioning and high comfort compared with the traditional body position type negative pressure bag fixation method, and can fix the testicles within the same effective position range each time, so it is convenient for accurate radiotherapy.

[0008] To achieve the above object, the present utility model provides the following technical solution: An adjustable radiotherapy fixator for male testicles, which comprises: a base, a lifting mechanism is provided at the bottom of the base, and the lifting mechanism is engaged with a lifting platform; a first bracket, the first bracket is a trough structure, and one end of the first bracket is provided with a first arm connected to the lifting platform; a second bracket, the second bracket is adapted to the top of the first bracket, and the second bracket is provided with a second arm overlapping and connected to the first arm; the first bracket and the second bracket are respectively provided with corresponding semi-circular grooves at one end far from the lifting platform, and the two semi-circular grooves form a window communicating with the inside of the first bracket.

[0009] Preferably, the lifting mechanism is fixedly connected to one end of the top of the base, a counterweight is provided at the top of the other end of the base, and a positioning groove is provided at the bottom of the base corresponding to the counterweight bottom.

[0010] Preferably, the lifting mechanism includes a lower fixing block fixedly connected to the base, and an upper fixing block provided above the lower fixing block. A pair of fixing columns are connected between the upper fixing block and the lower fixing block, and a threaded rod is provided between the two fixing columns. The top of the threaded rod penetrates through the upper fixing block and is provided with a handwheel; the lifting platform is fitted with the corresponding fixing column through a through shaft hole, and the lifting platform is provided with a threaded hole cooperating with the threaded rod.

[0011] Preferably, scales are respectively provided on each of the fixing columns, and scale rings are respectively provided on the top of the lifting platform corresponding to each of the fixing columns.

[0012] Preferably, one end of the lifting platform is provided with a positioning column and a fixing hole. The first arm and the second arm are provided with through holes corresponding to the positioning column and the fixing hole, and the first arm and the second arm are threadedly engaged with the fixing hole through a fixing screw passing through the through hole.

[0013] Preferably, the second bracket is provided with a positioning cover corresponding to the top of the window.

[0014] The beneficial effects of the present utility model are as follows: Compared with the fixing method of traditional body position negative pressure bags, this design has the advantages of accurate positioning and high comfort, and can fix the testicles within the same effective position range each time, so it is convenient for precise radiotherapy. The counterweight body facilitates the overall structural balance, and a fixing bracket can also be installed under the base through the positioning groove, thereby improving the flexibility of use of the overall device. Medical staff can drive the threaded rod through the handwheel to adjust the up and down position of the lifting platform to meet the external genital fixation needs of patients with different body shapes. The scale on the fixing column can be used to master the height of the lifting platform. During the adjustment process of the handwheel, the scale ring on the lifting platform can also facilitate better reading of the scale value. The positioning column and the fixing screw can effectively prevent the first bracket and the second bracket from shifting. Especially for the second bracket, the positioning column can also meet the angle constraint during the closing process to ensure that the second bracket can accurately align with the first bracket. The positioning cover can increase the contact area with the penis, so it can effectively avoid the discomfort of the outer edge of the window getting stuck on the penis.
