Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a protective device for radiotherapy during keloid surgery. Background Art

[0002] Keloid is a benign proliferative disease, which is the manifestation of skin scar tissue's response to trauma exceeding the normal range. Keloid originates from normal polyclonal fibroblasts. Under the stimulation of abnormal extracellular signals, fibroblasts proliferate excessively to form scar tissue, which is then replaced by collagen tissue. The skin loses its normal structure and manifests as keloid with a glassy appearance.

[0003] Currently, surgery is the most commonly used treatment for keloids. However, the recurrence rate of keloids removed by surgery alone is as high as 60% to 90%, and the range of the lesion may be larger than before surgery. Therefore, radiotherapy is required after surgery to reduce the risk of recurrence.

[0004] During radiotherapy, lead sheet is needed to cover the normal skin around the surgical wound to prevent the radiotherapy from damaging the normal skin. At present, when using lead sheet to cover the normal skin around the surgical wound, the lead sheet needs to be cut according to the shape of the wound, which is troublesome and laborious. In addition, the lead sheet is easily damaged during the cutting process, which is not convenient for the reuse of the lead sheet and increases the cost of use. Therefore, in view of the above technical problems, a keloid intraoperative radiotherapy protection device is proposed. Utility Model Content

[0028] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0029] See also Figures 1 to 3 In one embodiment, a keloid intraoperative radiotherapy protection device includes a counterweight base 10, a lifting assembly 20 and a protection mechanism 30.

[0030] The lifting assembly 20 is arranged on the counterweight base 10. The protection mechanism 30 includes a mounting frame 301, a plurality of lead blocks 303 and a fixing assembly. The mounting frame 301 is connected to the counterweight base 10 through the lifting assembly 20. The lifting assembly 20 can be adjusted to drive the mounting frame 301 to rise and fall. The bottom of both ends of the mounting frame 301 is respectively provided with a plurality of lead blocks 303 for sliding. The two corresponding groups of lead blocks 303 at both ends can abut against each other. The sides of the two adjacent groups of lead blocks 303 at the same end abut against each other. A through slot 304 is vertically opened on the mounting frame 301. The through slot 304 can be opened or sealed by sliding the plurality of lead blocks 303 respectively. The fixing assembly is arranged on the mounting frame 301 for fixing the plurality of lead blocks 303.

[0031] Specifically, the tops of the multiple groups of lead blocks 303 are all provided with T-shaped sliders 302, and the bottoms of the two ends of the mounting frame 301 are provided with multiple groups of T-shaped slide grooves 305, and the T-shaped sliders 302 are slidably arranged in the T-shaped slide grooves 305. The fixing assembly includes two groups of pressure rods 306; the tops of the two ends of the mounting frame 301 are provided with clearance grooves 3041 connected with the multiple groups of T-shaped slide grooves 305, one end of the two groups of pressure rods 306 is hinged on the mounting frame 301, and the other end is connected with the mounting frame 301 by clamping, and the pressure rods 306 are provided with rubber strips 3061, which are located in the clearance grooves 3041 and press the multiple groups of T-shaped sliders 302.

[0032] In the above embodiment, when in use, the counterweight base 10 is moved to make the mounting frame 301 located above the surgical wound, and then according to the shape of the wound, the clamping connection between the pressure rod 306 and the mounting frame 301 is first canceled, and then the pressure rod 306 is rotated to make the rubber strip 3061 withdraw from the clearance groove 3041. At this time, the rubber strip 3061 cancels the pressing of the T-shaped slider 302, and then multiple groups of lead blocks 303 are slid. The sliding of multiple groups of lead blocks 303 can open a through opening 308 in the through groove 304 that is similar to the shape of the surgical wound and larger than the size of the surgical wound. After the shape of the through opening 308 is adjusted, the pressure rod 306 is rotated in the opposite direction to make the pressure rod 306 clamped with the mounting frame 301 again. At this time, the rubber strip 3061 can press the T-shaped slider 302 again, so as to fix the multiple groups of lead blocks 303, and then fix the shape of the opening 308. Finally, the lifting component 20 drives the mounting frame 301 to descend. The mounting frame 301 descends and drives the multiple groups of lead blocks 303 to descend, so that the multiple groups of lead blocks 303 can cover the skin around the surgical wound and expose the surgical wound from the opening 308, thereby protecting the normal skin around the surgical wound during radiotherapy. By sliding the multiple groups of lead blocks 303, the shape of the opening 308 can be adjusted according to the shape of the surgical wound without cutting, which is convenient and labor-saving to use, and avoids damage to the lead, making it easy to reuse and reducing the cost of use.

[0033] On the basis of the above embodiment, further, one end of the two groups of pressure rods 306 is provided with a spring clip block 3062, and the mounting frame 301 is provided with two groups of spring clip slots 3042 correspondingly, and the spring clip block 3062 can be clamped in the spring clip slot 3042. By applying force to the spring clip block 3062 to elastically deform the spring clip block 3062 so that the spring clip block 3062 is clamped in the spring clip slot 3042 or withdrawn from the spring clip slot 3042, the pressure rod 306 can be clamped or separated from the mounting frame 301, and the pressure rod 306 and the mounting frame 301 are conveniently clamped or separated.

[0034] Please participate Figure 3 , Figure 4In one embodiment, a groove 3031 is provided on one side of the plurality of groups of lead blocks 303, and a protrusion 3032 is provided on the other side, and the protrusions 3032 in two groups of lead blocks 303 adjacent to each other at the same end are slidably arranged in the groove 3031. The tightness of the abutment between the two adjacent groups of lead blocks 303 can be improved by the cooperation between the groove 3031 and the protrusion 3032, and the shielding effect of the lead blocks 303 on the skin around the surgical wound can be further improved.

[0035] Please participate Figure 1 , Figure 2 In one embodiment, the lifting assembly 20 includes a column 201, an extension column 202 and a driving member; the column 201 is set on the counterweight base 10, and the extension column 202 can slide along the height direction of the counterweight base 10 and pass through the top of the column 201. The driving member is rotatably set on the extension column 202 and connected to the column 201. The rotating driving member can drive the extension column 202 to slide. A connecting rod 2021 is set at the top of the extension column 202, and the connecting rod 2021 is connected to the mounting frame 301.

[0036] Specifically, the driving member includes a screw rod 203 ; one end of the screw rod 203 is rotatably disposed on the extension column 202 , and the other end of the screw rod 203 is threadedly connected to the column 201 .

[0037] In the above embodiment, by rotating the screw 203, the screw 203 rotates and cooperates with the thread of the column 201 to move the screw 203, and the movement of the screw 203 can drive the extension column 202 to move. The movement of the extension column 202 can drive the mounting frame 301 to move through the connecting rod 2021, and the movement of the mounting frame 301 can drive multiple groups of lead blocks 303 to move to cover the skin around the surgical wound. It is convenient to drive the multiple groups of lead blocks 303 to move to cover the skin around the surgical wound, and stopping the rotation of the screw 203 can fix the extension column 202, thereby fixing the multiple groups of lead blocks 303, avoiding displacement of the multiple groups of lead blocks 303 during radiotherapy.

[0038] Please participate Figure 2 , Figure 3 On the basis of the above embodiment, further, a rotating seat 204 is provided at one end of the connecting rod 2021, and a rotating shaft 307 is provided on the mounting frame 301. One end of the rotating shaft 307 is rotatably arranged in the rotating seat 204. A fixing knob 2041 is threadedly connected to the circumference of the rotating seat 204. Rotating the fixing knob 2041 can make one end of the fixing knob 2041 come into contact with the circumference of the rotating shaft 307.

[0039] In the above embodiment, the fixation of the rotating shaft 307 can be cancelled by rotating the fixing knob 2041 to separate one end of the fixing knob 2041 from the rotating shaft 307. At this time, the rotating shaft 307 can be rotated to drive the mounting frame 301 to rotate. The rotation of the mounting frame 301 can drive the multiple groups of lead blocks 303 to rotate, thereby adjusting the angles of the multiple groups of lead blocks 303. When the angles of the multiple groups of lead blocks 303 are adjusted, the fixing knob 2041 can be rotated in the opposite direction to make one end of the fixing knob 2041 contact with the side of the rotating shaft 307 to fix the rotating shaft 307, thereby fixing the angles of the multiple groups of lead blocks 303, which is convenient for adjusting the angles of the multiple groups of lead blocks 303 to adapt to surgical wounds in different positions, thereby improving the practicality of the device.

[0040] The specific implementation of the above-mentioned keloid intraoperative radiotherapy protection device is as follows:

[0041] When in use, the counterweight base 10 is moved to make the mounting frame 301 located above the surgical wound. Then, according to the shape of the wound, the clamping connection between the pressure rod 306 and the mounting frame 301 is first canceled, and the pressure rod 306 is rotated to make the rubber strip 3061 withdraw from the make way slot 3041. At this time, the rubber strip 3061 cancels the pressing of the T-shaped slider 302. Then, by sliding multiple sets of lead blocks 303, the sliding of multiple sets of lead blocks 303 can open a through opening 308 in the through slot 304 that is similar to the shape of the surgical wound and larger than the size of the surgical wound. After the shape of the through opening 308 is adjusted, the pressure rod 306 is rotated in the opposite direction to make the pressure rod 306 clamped with the mounting frame 301 again. At this time, the rubber strip 3061 can press the T-shaped slider 302 again, thereby fixing the multiple sets of lead blocks 303, and then fixing the shape of the through opening 308. By rotating the screw 203 and the threaded cooperation with the column 201, the screw 203 can drive the extension column 202 to move downward. The downward movement of the extension column 202 can drive the mounting frame 301 to move downward through the connecting rod 2021. The downward movement of the mounting frame 301 can move the multiple groups of lead blocks 303 downward to cover the skin around the surgical wound and expose the surgical wound from the opening 308, thereby protecting the normal skin around the surgical wound during radiotherapy. Then, the rotation of the screw 203 can be stopped to fix the multiple groups of lead blocks 303 to avoid displacement of the multiple groups of lead blocks 303 during radiotherapy. By sliding the multiple groups of lead blocks 303, the shape of the opening 308 can be adjusted according to the shape of the surgical wound. No cutting is required, which is convenient and labor-saving to use, and it avoids damage to the lead, is easy to reuse, and reduces the cost of use.
