Problems solved by technology

At present, due to the lack of corresponding surgical auxiliary equipment, the patient needs to lie on his back during the operation. The assistant presses the breast with both hands to keep it fixed during the entire operation. The surgeon performs the puncture operation based on the guidance of B-ultrasound. Due to the large deformation error caused by pressing, it is necessary to cooperate with ultrasound equipment for multiple needle track adjustments to accurately insert into the tumor, which has high requirements for the doctor's operating skills and cooperation between doctors.

specific Embodiment approach 1

[0017] A breast cancer radiofrequency ablation fixing bracket according to this embodiment, such as figure 1 As shown, its composition includes: a headrest fixed base 1, an L-shaped multi-joint movable bracket 2, a curved chest compression piece 3, the headrest fixed base 1 is arranged at the bottom, and the upper surface of the headrest fixed base 1 is connected to the L-shaped multi-joint The bottom end of the vertical branch 4 of the movable support 2 is connected, and the horizontal branch 5 of the L-shaped multi-joint movable support 2 is movable to install the curved surface chest compression piece 3, and the concave surface of the curved surface chest compression piece faces the operator;

[0018] A group of through holes 6 are evenly distributed on the surface of the curved chest compression piece 3, and a spherical universal joint 7 is arranged in the middle of the upper surface of the curved surface chest compression piece 3, which is used for vertical branches 4 of t...

specific Embodiment approach 2

[0021] The difference from Embodiment 1 is that a breast cancer radiofrequency ablation fixing bracket in this embodiment, such as figure 1 As shown, one end of the horizontal branch 5 of the L-shaped multi-joint movable support 2 is also provided with a first set of holes 9, the central axis of the first set of holes 9 is perpendicular to the central axis of the rod body of the horizontal branch 5, and the first set of holes 9 A threaded through hole is set on the wall of the hole, the central axis of the threaded through hole is the same as that of the horizontal branch 5, the screw locking nail 10 is screwed in the threaded through hole, and the first set of holes 9 of the horizontal branch 5 is set in the vertical branch 4, and the horizontal branch 5 is fixed on the vertical branch 4 by screw locking nails 10;

[0022] The pin holder 11 is also set on the horizontal branch 5, and one end of the pin holder 11 is provided with a second sleeve hole 12, and the other end of t...

specific Embodiment approach 3

[0025] Different from the specific embodiment 1 or 2, the breast cancer radiofrequency ablation fixing bracket of this embodiment, such as figure 1 As shown, the surface of the horizontal branch 4 and the vertical branch 5 of the L-shaped multi-joint movable support 2 is provided with a standard scale, and the horizontal branch 4 and the vertical branch 5 of the L-shaped multi-joint movable support 2 are Hollow steel pipe.

Abstract

The invention discloses a breast cancer radiofrequency ablation fixing bracket. In the B-ultrasonic-guided radiofrequency ablation operation process, due to the lack of corresponding operation auxiliary instruments, a patient needs to lie on the back and lie flat in the operation, and an assistant presses breasts with hands in the whole operation process to keep the breasts in a fixed state. According to the breast cancer radiofrequency ablation fixing bracket, a headrest fixing base is arranged at the bottommost portion, the upper surface of the headrest fixing base is connected to the bottomend of a vertical branch of an L-shaped multi-joint movable bracket, and a curved-surface chest pressing piece is movably installed on a horizontal branch of the L-shaped multi-joint movable bracket;and a group of through holes are uniformly distributed in the surface of the curved-surface chest pressing piece, a spherical universal joint is arranged in the middle of the upper surface of the curved-surface chest pressing piece, and a hollow needle passage tube is arranged in the middle of the curved-surface chest pressing piece. By using the fixing bracket, mechanical pressing and fixed shape positioning are conducted on the breasts of a patient before an operation, a traditional assistant manual pressing mode is replaced, and other work of the whole operation can be conducted by a single person.

Description

technical field [0001] The invention relates to a fixed bracket for radiofrequency ablation of breast cancer. Background technique [0002] The female mammary gland is composed of skin, fibrous tissue, mammary glands and fat. Breast cancer is a malignant tumor that occurs in the mammary glandular epithelial tissue. B-ultrasound-guided radiofrequency ablation is an effective treatment for early breast cancer. It has a good curative effect due to short operation time, minimally invasive operation, small local trauma, and few postoperative complications. Compared with open surgery, it has Significant technical advantages. [0003] Because female breasts are mainly composed of fat, they are very soft. At present, due to the lack of corresponding surgical auxiliary equipment, the patient needs to lie on his back during the operation. The assistant presses the breast with both hands to keep it fixed during the entire operation. The surgeon performs the puncture operation based o...
