Description

Technical Field

[0001] The invention relates to the technical field of electron beam radiotherapy for post-operative ear keloid surgery, and in particular to an accurate and convenient device for electron beam radiotherapy for post-operative ear keloid surgery. Background Art

[0002] In recent years, the number of ear keloids has continued to increase. Surgery + radiotherapy is currently the most perfect clinical solution. Clinical studies have found that fibroblasts near the incision after surgery will soon start the proliferation program for tissue repair. Fibroblasts at this stage are most sensitive to radiation. Therefore, it is necessary to perform the first electron beam irradiation within 24 hours after the operation to the area centered on the surgical incision and expanding 1 cm around it.

[0003] Irradiation of tissues near the incision with electron beams can inhibit the activity of local fibroblasts, reduce the ability of fibroblasts to proliferate and secrete collagen, and thus reduce the recurrence rate of keloids. Regarding irradiation of tissues near the incision with electron beams, the current operation process often ignores the impact of radiotherapy compensators and skin cavities on radiotherapy doses.

[0004] Therefore, based on the purpose of reducing the gaps between electron beam radiotherapy of ear scars and making the radiotherapy dose more stable and the therapeutic effect better, we proposed an accurate and convenient device for postoperative electron beam radiotherapy of ear bruises and keloids. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an accurate and convenient device for postoperative electron beam radiotherapy of ear eczema keloids.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The invention discloses an accurate and convenient device for electron beam radiotherapy after operation for ear ecchymoses, and an accurate and convenient device for electron beam radiotherapy after operation for ear ecchymoses, comprising an under-ear base ring and an above-ear card which matches the under-ear base ring.

[0008] A lower clamping ring is provided on a portion of the outer surface of the base ring under the ear corresponding to the ring hole.

[0009] An upper clamping ring matching with a lower clamping ring is arranged on the inner side surface of the ear-top clamping plate, and a filling cavity is formed between the inner ring surface of the upper clamping ring and the inner side surface of the ear-top clamping plate.

[0010] The inner surface of the ear card corresponding to the lower clamping ring is provided with a plurality of spaced clamping rods, the other end of the clamping rod is provided with a clamping block facing the lower clamping ring, and the outer ring surface of the lower clamping ring is provided with a corresponding clamping groove corresponding to the clamping block.

[0011] Preferably, the lower clamping ring and the base ring under the ear are an integrated structure.

[0012] Preferably, the inner surface of the under-ear base ring is provided with a plurality of annular grooves.

[0013] Preferably, the ear card and the upper clamp ring are an integrated structure.

[0014] Preferably, the card rod and the upper ear card are an integrated structure, and the card rod and the upper clamping ring are separated.

[0015] The accurate and convenient device for postoperative electron beam radiotherapy of ear eczema and keloid proposed by the present invention has the beneficial effect that: during the application of the technical scheme, the base ring under the ear is fixed around the ear, and the card above the ear is fixed on the lower clamping ring. At this time, the gap between the lower clamping ring and the ear and the filling cavity are filled with radiotherapy compensating materials respectively, which can maximize the reduction of the gap existing in the process of electron beam radiotherapy of ear scars, thereby facilitating more accurate and stable radiotherapy doses and better therapeutic effects. The whole device has a simple structure and is easy to operate, which is conducive to its use in the process of electron beam radiotherapy of postoperative ear eczema and keloid.
