Novel radiotherapy body surface location device
Technical Field
The utility model relates to the technical field of postoperative treatment of cancers, in particular to a novel radiotherapy body surface positioning device.
Background
Breast cancer is a common malignant tumor for women, and most patients have postoperative adjuvant radiotherapy symptoms. The breast of the side chest wall is lost after the breast cancer operation, the residual chest wall is very shallow and thin, and is the part needing to be irradiated in the radiotherapy treatment, and the operation incision needs to be developed to assist the target region to draw when the CT is scanned and positioned before the radiotherapy. At present, the operation incision is marked by a lead wire clinically, and the lead wire has more imaging artifacts under CT, so that the speed and the accuracy of a clinician for delineating a target area are seriously influenced. The existing target region delineation system of the hospital has the function of automatically delineating normal tissues, and the automatic delineation accuracy depends on the density difference between adjacent tissues. The lead wire positioning operation incision has the following defects: when artifacts exist, the skin and pectoral fascia after operation are not clearly displayed, the skin delineation is inaccurate, manual modification is needed, and time and labor are wasted; when the artifact and the rib are unclear, the back bound of the target area is difficult to accurately draw, and the CTV back bound is easy to draw under the pectoralis muscle and tendon membrane or on the rib, so that the adverse reaction of radiotherapy is aggravated; and the length difference of the surgical incision of different patients is large, and lead wires with various lengths need to be prepared for standby so as to meet the use requirements of different scars.
Disclosure of Invention
In order to solve the problems in the prior art, the utility model discloses a novel radiotherapy body surface positioning device which can provide clear CT scanning development.
The technical scheme adopted by the utility model is as follows: the positioning device comprises a transparent soft pipe body, developing solution is filled in the pipe body, soft transparent positioning seal heads are arranged at two ends of the pipe body respectively, the two ends of the pipe body are fastened at two ends of the pipe body in a sleeved mode through the positioning seal heads, pipe orifices at two ends of the pipe body are sealed, wing plates are arranged at the bottom of the positioning seal heads, and transparent positioning adhesive tapes are arranged on the positioning seal heads and the pipe body respectively. The length of the tube body can be cut according to the use requirement, a developing solution is injected into the tube body by using an injector, two ends of the tube body are respectively sealed by using positioning seal heads, the tube body is matched with the positioning seal heads in size and is tightly sealed at the two ends of the tube body by virtue of friction force, when the device is applied, the positioning seal heads at the two ends are respectively positioned at two ends of an operation incision, the tube body is pasted and fixed along the incision by using a transparent adhesive tape, and wing plates on the positioning seal heads at the two ends can prevent the tube body from rolling. The soft pipe body is convenient to bend and fit with the appearance of the knife edge, and the soft positioning end socket cannot damage the human body when being applied.
Furthermore, length scale marks are printed on the pipe body. Set up length scale mark and be convenient for select suitable length and carry out the body and tailor.
Furthermore, the tube body is sleeved with a soft transparent positioning sleeve, positioning plates respectively extend out of two sides of the positioning sleeve, and a transparent positioning adhesive tape is arranged on the sleeve. The positioning sleeve is used for assisting in positioning the tube body and positioning the tube body by friction.
Furthermore, the bottom surfaces of the wing plate of the positioning seal head and the positioning plate of the positioning sleeve are respectively provided with anti-skid convex patterns.
Compared with the prior art, the novel radiotherapy body surface positioning device disclosed by the utility model has the advantages that the transparent soft tube body is used for containing the developing solution, the soft tube body is convenient to bend, the tube body filled with the developing solution is arranged along the knife edge, the positioning seal heads at the two ends are positioned at the two ends of the knife edge, the tube body is sleeved with the positioning sleeve with the positioning plate for auxiliary positioning, and the positioning sleeve is adhered and fixed through the transparent positioning adhesive tape. When CT scanning is carried out, the positioning device has clear imaging and can clearly outline a target area.

Detailed Description
The utility model is further described with reference to the following figures and specific embodiments.
As shown in fig. 1, in an embodiment of the novel radiotherapy body surface positioning device disclosed in the present invention, the positioning device includes a transparent soft tube body 1, and length scale lines 11 are disposed on an outer surface of the tube body 1 along a length direction thereof. The developing solution is filled in the tube body 1, the two ends of the tube body 1 are respectively provided with the transparent positioning seal heads 2, the inner diameter of each positioning seal head 2 is matched with the outer diameter of the tube body 1, and the tube openings at the two ends of the tube body 1 are sleeved and fastened at the two ends of the tube body 1 and sealed. The bottom of the positioning end socket 2 is provided with a wing plate 21.
The positioning sleeve 3 is sleeved on the tube body 1, the inner diameter of the positioning sleeve 3 is matched with the outer diameter of the tube body 1, the positioning plates 31 extend out of two sides of the positioning sleeve 3 respectively, the positioning sleeve 3 is pushed forcefully to slide along the tube body 1, and the positioning sleeve can be positioned on the tube body 1 by means of self friction force. The tube body 1, the positioning end enclosure 2 and the positioning sleeve 3 are all made of medical-grade nontoxic polyvinyl chloride materials, and are soft, colorless and transparent.
The wing plate 21 and the positioning plate 31 are integrally formed with anti-slip ribs 22 on their lower surfaces, respectively. The positioning device is provided with a plurality of sections of transparent positioning adhesive tapes 4, and the positioning adhesive tapes 4 are respectively arranged at the positioning end sockets 3 at the two ends and the positioning sleeve 3 in the middle. When the device is applied, if the knife edge is bent more, more positioning adhesive tapes 4 can be used for directly attaching the bent section of the tube body 1 to the skin of a patient.
The length of body 1 can be tailor according to the operation requirement according to scale mark 11, uses the syringe to pour into the developer into to body 1, and the both ends of body 1 are sealed with location head 2 respectively, and body 1 suits with location head 2 size, relies on frictional force fastening seal at the both ends of body 1, and the position sleeve 3 cover is established on body 1 to forcefully remove the middle part position. When the positioning sealing head is used, the positioning sealing heads 2 at two ends are respectively positioned at two ends of an operation incision, the tube body 1 is adhered and fixed along the incision through the multi-section transparent positioning adhesive tapes 4, and the wing plates 21 on the positioning sealing heads 2 at two ends and the positioning plates 31 on the positioning sleeves 3 can prevent the tube body 1 from rolling.
The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the scope of the utility model, which is defined by the appended claims and the description of the utility model.
