Description

Technical Field

[0001] The invention relates to a suction cup adsorption type breast tissue fixing device, belongs to the field of medical instruments, and is particularly applicable to breast intervention surgery in a prone position. Background Art

[0002] In breast interventional surgery, the patient's prone position helps improve the safety of the surgery. In the prone position, the breast tissue is naturally drooping. At the same time, due to the high fluidity of the breast tissue itself, it is easy to deviate, which will make it impossible to perform accurate surgical operations on the lesions on the breast tissue during surgery. Therefore, it is necessary to design a device for fixing breast tissue to limit the flow of breast tissue, assist in the execution of biopsy surgery, ensure the accuracy of biopsy sampling, and thus improve the work efficiency of breast interventional surgery. There are some patents disclosed for the design of devices for fixing breast tissue, but the devices currently designed still have unresolved problems. For example, the utility model patent with the authorization announcement number CN 204337045 U discloses a breast fixator, which includes an upper fixing ring, an intermediate ring and a lower fixing ring, wherein a plurality of connecting rods are arranged between the upper fixing ring and the lower fixing ring, the connecting rods are composed of a plurality of groups of telescopic short rods, and a sleeve is arranged on the inner side of the intermediate ring, and the sleeve corresponds to the connecting rod. Although the patent can be adjusted according to the size of the patient's breast, the adjustable range is small, the operation is cumbersome, and the fixing method is an extrusion type. In order to fit the breast tissue, the lesions of the breast tissue can only be fixed by extrusion, which increases the pain of the patient during the operation, and the fixing device cannot be quickly adjusted and locked. Therefore, it is very necessary to design a suction cup adsorption breast fixation mechanism for prone position. Summary of the invention

[0003] In view of the above problems, the problem to be solved by the present invention is to provide a suction cup adsorption type breast fixation mechanism for prone position and a method of use, which can clamp breast tissue during breast intervention surgery, thereby stabilizing the lesion point and improving surgical accuracy.

[0004] A suction cup adsorption type breast fixation device for prone position, comprising a prone support, a breast tissue clamping device, and a position adjustment device, characterized in that: the breast tissue clamping device is composed of two completely identical opening and closing mechanisms and an adsorption device, each opening and closing mechanism is equipped with four completely identical short optical bars I, a square optical bar connector, a T-shaped rack, a square rack, a gear, and a square base, the adsorption device is composed of an arc-shaped suction cup support, a ball pair, and a vacuum suction cup, two short optical bars I are connected by a square optical bar connector, the bottom end of the T-shaped rack is connected to the short optical bar I, and the upper end is meshed with the square rack, and the side meshing surface of the T-shaped rack is meshed with the gear, the bottom end of the arc-shaped suction cup support is connected to the square rack, and the upper end is connected to the vacuum suction cup through a ball pair.

[0005] Preferably, the vacuum suction cup material is soft rubber material, and each vacuum suction cup of the breast tissue clamping device is driven by the rotation of the motor to engage the gear rack, thereby driving the vacuum suction cup to perform adsorption and desorption movements. The connection side of the square rack and the suction cup bracket is set to the initial position, the T-shaped rack length is 75mm, and the gear diameter is 200mm. At this time, the maximum distance between the symmetrically distributed square racks is 200mm, and the diameter of the circle surrounded by four completely identical and symmetrically distributed vacuum suction cups and the range of fixed breast tissue are 50mm to 200mm.

Before the operation, the doctor controls the rotation of the motor I to control the two breast tissue clamping devices to produce relative movement, so that the distance between the two breast tissue clamping devices is suitable for the distance between the patient's two breasts. At the same time, the doctor controls the motor I rotates, driving the gear to rotate clockwise, and the T-shaped rack meshing with it moves left and right, thereby driving the square rack meshing with the meshing surface on the T-shaped rack to move forward, and then driving the vacuum suction cup to retract toward the center of the breast tissue. When the opening and closing mechanism reaches the ideal position, the doctor controls the motor to stop moving. At this time, the four vacuum suction cups have been adsorbed on the four sides of the patient's breast tissue, thereby achieving the purpose of stabilizing the patient's breast tissue and preparing for the subsequent puncture biopsy operation; after the operation is completed, the doctor controls the motor to reverse, controls the breast tissue clamping device to move in the opposite direction, releases the breast tissue, and removes the constraint on the patient's breast tissue.

[0007] The beneficial effects of the present invention are:

[0008] 1. The vacuum cup of the suction cup fixation device is made of soft rubber, which avoids rigid contact with breast tissue and can effectively improve the patient's comfort in the fixed state;

[0009] 2. It uses four vacuum cups and is connected to the arc-shaped bracket with a ball pair, which can fully absorb the breast tissue, perfectly fit and envelop the surface of the breast tissue, and improve the fit between the breast tissue clamping device and the breast shape;
