Description

Technical Field

[0001] The utility model relates to the technical field of source applicator brackets, in particular to a rotatable source applicator fixing bracket. Background Art

[0002] An applicator is a special container that is pre-placed into a human cavity, pipe, or tissue space during close-range radiotherapy for the radiation source to reside or move and for treatment to be implemented. An applicator tube is a specific form of an applicator, usually referring to a pipe or device used to transport the radiation source. When treating scars, the flexible applicator tube needs to be shaped to the shape of the scar and adhered closely to both sides of the scar. Traditional patch radiotherapy involves directly attaching the applicator to both sides of the patient's scar for treatment.

[0003] After searching, the application with patent number 02023278529.X discloses a fixing bracket for a skin applicator, comprising a first fixing bracket, a second fixing bracket, a plurality of plastic adjustment components, a first sleeve, a second sleeve, a first plastic traction member, and a second plastic traction member. The first plastic traction member and the second plastic traction member are both fixedly connected between the first fixing bracket and the second fixing bracket to form a fixing bracket body, and the first plastic traction member and the second plastic traction member are symmetrically arranged at both ends of the fixing bracket body; the first fixing bracket and the second fixing bracket are each provided with two first through holes, and the first sleeve and the second sleeve pass through the first through holes and are spaced apart and distributed between the first plastic traction member and the second plastic traction member;

[0004] Although the fixed bracket used for the skin applicator allows the applicator tube to pass through the first sleeve and the second sleeve, and can also protect the flexible applicator tube, which is conducive to the installation of the applicator tube, the fixed bracket used for the skin applicator adjusts the contour of the applicator tube through plastic material, and the plastic material is easy to deform and cannot keep the applicator tube at a specific degree of bending, resulting in the contour of the applicator tube easily changing during use, and then the degree of matching with the scar contour is not high.

[0005] Therefore, we propose a rotatable applicator fixing bracket. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the utility model provides a rotatable applicator fixing bracket, which solves the problem that the existing device adjusts the contour of the applicator tube through plastic material, causing the contour of the applicator tube to easily change during use, and then the degree of matching with the scar contour is not high.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a rotatable source applicator fixing bracket, comprising a fixing plate, wherein two fixing plates are provided, and adjustment plates are fixedly installed on both sides of the top surfaces of the two fixing plates, and an adjustment slot is formed on one side of the top surface of the adjustment plate near the middle of the fixing plate, and a fixing frame is provided on the adjustment plate;

[0008] The fixing frame includes a slider, a limit plate, a fixing block, a third bolt, a connecting rod, a first annular plate, a second annular plate, an adjusting frame, a first threaded hole, a first bolt, a sliding frame, a sleeve, a second threaded hole and a second bolt. The slider is slidably mounted inside the adjusting groove. A connecting rod in the shape of an "L" is fixedly mounted on the top surface of the slider. The first annular plate is fixedly mounted on the end of the connecting rod away from the slider. The adjusting frame is rotatably mounted on the inner ring of the first annular plate through the bearing ring. The first threaded holes distributed in a linear array are fixedly mounted on the inner wall of the adjusting frame.

[0009] Preferably, a second threaded hole is provided on the side wall of the sliding frame, a second bolt is threadedly mounted in the second threaded hole, and the end of the second bolt passes through the second threaded hole and contacts the side wall of the sliding rod. When the sliding frame slides to an appropriate position on the sliding rod, the second bolt is rotated so that its end contacts the side wall of the sliding rod, thereby limiting the sliding frame.

[0010] Preferably, a second annular plate is fixedly mounted on the bottom surface of the first annular plate, and first threaded holes are provided at the four corners of the top surface of the adjustment frame. A first bolt is threadedly sleeved in the first threaded hole, and the end of the first bolt passes through the first threaded hole and contacts the top surface of the second annular plate. When the adjustment frame is rotated to an appropriate angle, the adjustment frame can be limited by rotating the first bolt so that its end contacts the top surface of the second annular plate.

[0011] Preferably, a limit plate is fixedly mounted on the bottom surface of the slider, and the top surface of the limit plate contacts the bottom surface of the adjustment plate, wherein the slider can be limited by the limit plate to prevent the slider from detaching from the adjustment slot.

[0012] Preferably, a limiting groove is provided on the side of the top surface of the adjusting plate away from the middle of the fixed plate, and a fixing block is fixedly installed on the top of the slider away from the connecting rod. A third bolt is threadedly sleeved on the middle part of the fixing block, and the bottom end of the third bolt passes through the fixing block and contacts with the bottom surface of the limiting groove. When the slider slides to an appropriate position in the adjusting groove, the slider can be limited by rotating the third bolt so that its bottom end contacts with the bottom surface of the limiting groove.

[0013] Preferably, fixing holes are symmetrically provided on both sides of the top surface of the fixing plate, wherein the fixing plate can be fixed at a specific position by passing screws through the fixing holes.

[0014] The utility model provides a rotatable source applicator fixing bracket, which has the following beneficial effects:

[0015] The rotatable applicator fixing bracket facilitates moving the position of the adjustment frame by pushing the slider to slide inside the adjustment groove, and rotates the adjustment frame so that the scar is completely located in the inner circle of the adjustment frame. By pushing the sliding frame close to the scar contour position to move along the side wall of the sliding rod, it is convenient to adjust the position of the sliding frame and the sleeve on its top surface, so that the position of the sleeve can better match the scar contour, and by rotating the second bolt so that its end contacts the side wall of the sliding rod, the sliding frame and the second threaded hole can be limited and fixed, and then the flexible applicator tube can be passed through the sleeve to match the contour of the flexible applicator tube with the scar, thereby achieving the purpose of improving the matching degree between the applicator tube and the scar, and solving the problem that the existing device adjusts the contour of the applicator tube by plastic material, which causes the contour of the applicator tube to change easily during use, and then the matching degree with the scar contour is not high.
