Description

3D prints breast cancer operation baffle

Technical Field

The utility model relates to a medical auxiliary assembly, concretely relates to 3D prints breast cancer operation baffle.

Background

Standard breast MRI takes a prone position, and due to gravity, the breast shape exhibits the following changes: the breast is vertically downward, the interface is in an inverted cone shape, the PNL line (the posterior line of the nipple) is prolonged, the gland is compact and concentrated, the tension of the suspensory ligament is high, and the gap behind the breast is enlarged; the spatial location of the lesion changes as follows: far from the chest wall, near the line of PNL and the skin. The standard posture mammary gland MRI has the advantages that the lesion detail display is clearer, the accurate diagnosis of imaging doctors is facilitated, however, the examination posture is inconsistent with the operation posture, and the space position and the boundary of the mammary gland lesion cannot be truly reflected. When the breast is examined by the supine position mammary gland MRI, the breast integrally moves outwards, the skin and the gland are loose, the nipple and the focus are closer to the chest wall and farther from the PNL line, the space position and the boundary of the focus in the gland can be reflected more truly, and the guiding of the surgical design has more practical significance.

After the breast MRI examination position (prone position) is changed into a breast operation position (supine position), the focus is relatively displaced to different degrees, and at the moment, if the breast cancer breast-conserving operation is guided by the prone position MRI, the boundary and the excision range of the tumor focus are not accurate enough, so that the tumor focus is possibly remained, and the secondary operation rate and the local recurrence rate are increased. In clinical work, the following methods are often adopted to assist in locating the focus: 1. ultrasonic positioning before an operation, 2, placing a positioning marker before the operation, 3, skin tattoo positioning before the operation, and 4, palpation positioning under direct vision in the operation. The methods need ultrasound, radiology and surgeons to complete in a cooperative mode, have strong specialty, are difficult to operate, are not high in repeatability, still need the surgeons to determine the distance between the tumor focus boundary and the safe incisal margin through experience during actual operation in the operation, and still have great difference with preoperative positioning.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above purpose, the utility model adopts the following technical scheme: A3D printing breast cancer surgical guide plate comprises a guide plate main body, wherein a tumor center hole is formed in the guide plate main body and is determined according to the center position of a tumor; tumor margin indicating holes are formed in the periphery of the tumor center hole and are determined according to the positions of tumor margins; equidistant injection holes are arranged outside the tumor margin indicating hole; the edge of the guide plate main body is provided with two positioning points which are a first positioning point and a second positioning point respectively, the first positioning point is of a circular hole-shaped structure, and the first positioning point is a nipple position; the second positioning point is any point on the edge of the guide plate main body, which is 5cm away from the tumor edge indicating hole; the guide plate is characterized in that a fixing point is arranged on the guide plate main body, the fixing point is of a sticking structure, and a direction mark is arranged on the guide plate main body.

Further, the injection holes are annularly distributed around the tumor margin indicating hole; at least four groups of injection holes are arranged at equal intervals.

Further, the interval of each group of the injection holes is 5 mm.

Further, a depth indication column is arranged at a position close to the injection hole, and the height of the depth indication column is determined according to the distance between the tumor and the skin.

Furthermore, the depth indication column is provided with scales or steps, and each step of the steps on the depth indication column is 5 mm.

The utility model discloses an operation baffle main part effect can prevent the breast displacement, confirms focus position and boundary according to the focus data that supine position MRI provided, and supplementary planning excision scope will improve the clinical operation that the doctor implemented the breast protection art greatly, and the pathology security of guarantee incisional wound improves the success rate of breast protection art, reduces secondary operation and local recurrence rate, has great clinical application and worth.

Detailed Description

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "longitudinal", "lateral", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In order to facilitate a better understanding of the improvements of the present invention for those skilled in the art, the present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1, a 3D printing breast cancer surgical guide plate is characterized in that firstly nuclear magnetic resonance data of a patient is imported, three-dimensional model data of the skin and the tumor of the patient are reconstructed, a 3D printing breast cancer surgical guide plate main body 1 is determined, the center and the edge position of the tumor are determined according to the nuclear magnetic resonance data of the patient, and the position of a tumor center hole 2 is determined on the guide plate main body 1; the position of the tumor center hole 2 is the position of the tumor center point in the nuclear magnetic resonance data of the patient, tumor edge indicating holes 3 are arranged around the tumor center hole 2, and the tumor edge indicating holes 3 are the positions of the tumor edges in the nuclear magnetic resonance data of the patient; an injection hole 4 is arranged outside the tumor margin indicating hole 3, and the distance between the injection hole 4 and the tumor margin indicating hole is 310 mm; the edge of the guide plate main body 1 is provided with two positioning points 5, the two positioning points 5 are a first positioning point 51 and a second positioning point 52 respectively, the first positioning point 51 is in a circular hole-shaped structure, and the first positioning point 51 is the nipple position of a patient; the second positioning point 52 is any point 35 cm away from the tumor edge indicating hole on the edge of the guide plate main body 1; the guide plate main body 1 is provided with a fixing point 6, and the fixing point 6 is a sticking structure, can be a structure extending out of the guide plate main body 1, and can also be a sticking structure arranged at the edge position of the guide plate main body 1; the guide plate main body 1 is provided with a direction mark 7.
