Breast Conserving Specimen Taking Table for Breast Cancer

Abstract

The invention relates to a breast cancer breast-conserving specimen sampling and measuring platform which is characterized in that a measuring table 3, a sampling device 4 and a specimen fixing device 5 are arranged on a pedestal 2 inside a box body 1; the measuring table 3 is provided with a light box 6; a glass plate 7 and grid measuring paper 8 are arranged above the light box 6; two sides of the light box 6 are provide with a camera mount 9; a pan-tilt 10 is disposed on the camera mount 9; according to the sampling device 4, a knife rest 11 is arranged inside the box body 1; the knife rest 11 is provided with a blade flute 12, a handle 13 and a blade 14; the bottom of the knife rest 11 is provided with chutes 15; slide rails 16 are mounted inside the box body 1; the knife rest11 can reciprocate along the slide rails 16; the specimen fixing device 5 is provided with a specimen slot 17 which is fixed on the pedestal 2; a screw lift 18 is arranged inside the specimen slot 17; the upper end of the screw lift 18 is provided with a baseboard 19 which is used for placing a mammary tissue specimen; to match the baseboard 19, a specimen pressing and fixing device 22 is arranged; a pressing plate 26 is arranged on the specimen pressing and fixing device 22; and a screw lift 27 drives the pressing plate 26 to move up and down.

Description

technical field [0001] The invention belongs to the technical field of devices for measuring breast cancer breast-conserving specimens in medical equipment, and in particular relates to a breast cancer breast-conserving specimen margin measuring platform. Background technique [0002] Breast cancer is the most common malignancy in women. There is no difference in the efficacy of breast-conserving surgery and radical surgery for early breast cancer. Obtaining negative surgical margins is the basic requirement for the success of breast-conserving surgery, and the pathological status of the surgical margins is the most important risk factor for postoperative ipsilateral breast recurrence. Radiotherapy after breast-conserving surgery for breast cancer significantly reduces the recurrence rate of the ipsilateral breast. Accelerated partial breast irradiation (APBI) is used as an alternative mode of whole breast irradiation (WBI) for patients with partial breast-conserving therap...

AI Technical Summary

Problems solved by technology

Radiotherapy after breast-conserving surgery for breast cancer significantly reduces the recurrence rate of the ipsilateral breast. Accelerated partial breast irradiation (APBI) is used as an alternative mode of whole breast irradiation (WBI) for patients with partial breast-conserving therapy, APBI The clinical target volume (CTV) is defined as the surgical area and the surrounding 1-2 cm boundary range, in which negative surgical margins are an important guarantee for the success of APBI treatment, and the surgical cavity with negative surgical margins is determined by the APBI target volume. Basic, the pathological evaluation of resection margins in the past mainly included "5-point method (upper, lower, inner, outer, and base margin)" and "12-point method (hourly method, circular cutting the entire circle)", both of which are manually cut Tissues, limited materials, uneven thickness of tissue slices, low accuracy

At the same time, the tissue shrinkage is caused during the specimen processing, which affects the accurate judgment of the position of the resection margin.
