Description

A breast locator

Technical Field

The invention relates to the technical field of medical devices, in particular to a breast locator.

Background Art

The mammary gland is located between the superficial and deep layers of the superficial fascia under the skin. The superficial fascia extends into the breast tissue to form a cord-like lobular septum, one end of which is connected to the pectoralis fascia and the other end is connected to the skin, fixing the mammary gland in the subcutaneous tissue of the chest. During breast surgery, since each person's breasts are different, the patient needs to lie on the operating table, and the patient's breasts may collapse, which is not conducive to medical staff performing surgery on the patient's breasts.

For example, a Chinese patent with publication number "CN211658380U" discloses "an auxiliary positioner for breast surgery", whose main structure includes an annular mounting plate, a positioning mechanism, a rotating mechanism, a limiting mechanism, a heat preservation mechanism, a power supply mechanism, and an annular rubber pad. The positioning mechanism is rotatably connected to the upper end of the annular mounting plate. The positioning mechanism includes a hemispherical cover, a through port, an arc plate, a cavity, a suction cup, a threaded rod, a pump body, an air suction pipe and a branch pipe. The hemispherical cover is rotatably connected to the upper end of the annular mounting plate, and the through port is opened on the side wall of the hemispherical cover, the arc plate is located in the hemispherical cover, and the cavity is opened in the arc plate, the suction cup is fixedly mounted on the side wall of the arc plate and is connected to the cavity, the threaded rod is rotatably connected to the side wall of the arc plate, and the end of the threaded rod away from the arc plate passes through the hemispherical cover and is threadedly connected to it.

When the above-mentioned auxiliary positioner for breast surgery is working, the annular mounting plate is used to encircle the patient's breast, the hemispherical cover is rotated to align the opening with the position where the patient needs to undergo surgery, the threaded rod is rotated to bring the arc plate close to the patient's breast, the pump body is turned on, the suction pipe generates suction, and the suction cup generates suction through the branch pipe and the cavity to suction and connect the patient's breast, and the threaded rod is rotated again to retract the arc plate, thereby pulling the breast apart to prevent the breast from collapsing during the operation and making it inconvenient to perform the operation. The patient's breast can then be operated on from the opening.

From the above description, we can know that when it is working, it uses two symmetrically arranged suction cups to perform adsorption-type position limiting on the patient's breast. Due to the symmetrical adsorption, the positioning effect after adsorption on the patient's hemispherical breast is relatively poor (because the force points of the breast are symmetrically designed at two points). The equipment performs surgery on the breast inside the hemispherical cover through the opening, which seriously reduces the doctor's operating space and seriously affects the doctor's control and field of vision.

In order to make the breast in a straight state and prevent the occurrence of breast collapse, please refer to Figures 1, 2 and 5. It is necessary to set up an elastic tightening mechanism 2, which is provided with a lower movable plate 21 capable of driving the lower arc-shaped shell 11 to move along the axial direction, an upper movable plate 22 located directly above the lower movable plate 21 and capable of driving the upper fan-shaped shell 12 to move along the axial direction, and a coil spring 25 located between the lower movable plate 21 and the lower movable plate 21 and capable of exerting forces in opposite directions on the lower movable plate 21 and the lower movable plate 21. First, the upper movable plate 22 is pressed to make the coil spring 25 in a continuous compression state, and then the lower arc-shaped shell 11 and the upper fan-shaped shell 12 are adsorbed on the patient's breast area, and the pressure on the upper movable plate 22 is released. The coil spring 25 is reset under its own elastic action, so that the lower arc-shaped shell 11 and the upper fan-shaped shell 12 move away from each other, so that the breast is in a straight state, thereby preventing the occurrence of breast collapse.

As for the specific structure of the elastic tightening mechanism 2, please refer to Figure 5, which includes a lower movable plate 21 and an upper movable plate 22, one side of the lower movable plate 21 is fixedly mounted on the outer circumferential surface of the middle annular plate 14, and one side of the upper movable plate 22 is fixedly mounted on the outer circumferential surface of the upper annular plate 15, and a rod body through hole 24 connecting the upper and lower ports thereof is provided in the plate body of the upper movable plate 22, a longitudinal limiting rod 23 penetrating the rod body through hole 24 is fixedly mounted on the upper end surface of the lower movable plate 21, a top limiting plate 26 is fixedly mounted on the top end of the longitudinal limiting rod 23, and a coil spring 25 is placed on the outer periphery of the rod body of the longitudinal limiting rod 23 between the lower movable plate 21 and the upper movable plate 22, the coil spring 25 is in a compressed state, and the elastic strength of the coil spring 25 is sufficient to keep the patient's breast in a straight state.

In order to prevent the patient's breast from being damaged by excessive gas suction, please refer to Figures 1, 2, 6 and 7. A suction strength control mechanism 3 is required, wherein a longitudinal hollow shell 31 fixedly mounted on the top of the upper fan-shaped shell 12 and connected to the air area inside the upper fan-shaped shell 12 is provided inside thereof, and a cylindrical elastic gas membrane 34 located inside the longitudinal hollow shell 31 and deforming inwards after being subjected to the gas force inside the longitudinal hollow shell 31, thereby blocking the gas flow channel, is provided. A suction device is selected, and the suction head of the suction device is inserted into the air valve, and then , turn on the vacuum device, and the gas inside the gas flow cavity 33 is extracted.

Due to the effect of gas suction, the breast will be adsorbed on the inner circumference of the lower arc-shaped shell 11 and the upper fan-shaped shell 12. When the suction force is greater than the elastic strength of the cylindrical elastic air membrane 34, the cylindrical elastic air membrane 34 will bend inward until the cylindrical elastic air membrane 34 blocks the gas flow cavity 33, thereby preventing the gas suction force from being too large and causing damage to the patient's breast.

As for the specific structure of the suction intensity control mechanism 3, please refer to Figures 6 and 7, which includes a longitudinal hollow shell 31, the bottom end of which is provided with a lower fixing plate 32 which is integrally formed with the lower fixing plate 32 and fixedly mounted on the arc-shaped end surface of the upper fan-shaped shell 12, the interior of the longitudinal hollow shell 31 is provided with a gas flow cavity 33, the top end of the longitudinal hollow shell 31 is provided with a second gas flow hole 35 which is connected to the gas flow cavity 33 and has a gas valve installed therein, and the longitudinal hollow shell 31 The bottom end is provided with a No. 3 gas flow hole 36 connecting the bottom end of the gas flow cavity 33 and the No. 1 gas flow hole 111. The longitudinal hollow shell 31 is embedded with a cylindrical elastic air membrane 34 on the inner circumferential surface of the gas flow cavity 33. In order to have deformation blocking capability, it is necessary to make the cylindrical elastic air membrane 34 a cylindrical structure made of rubber material with elastic extension effect. The circumferential surface of the longitudinal hollow shell 31 is provided with a ventilation groove 37 connecting the external space and the peripheral area of the cylindrical elastic air membrane 34.

When in use, the lower arc-shaped shell 11 is covered on the root of the patient's breast, and the bottom of the lower annular plate 13 is made to contact the patient's chest, the upper movable plate 22 is pressed, so that the spiral spring 25 is in a continuous compression state, and then the upper fan-shaped shell 12 is covered on the vicinity of the patient's nipple, and the lower gas reserved cavity 18 and the corresponding breast part of the patient form a closed area, and the upper gas reserved cavity 19 and the corresponding breast part of the patient form a closed area, a vacuum device is selected, the vacuum head of the vacuum device is inserted into the air valve, and then the vacuum device is turned on, and the air is located in the air valve. The gas inside the body flow cavity 33 is extracted. Similarly, the gas inside the lower gas reserved cavity 18 and the upper gas reserved cavity 19 is extracted. Due to the effect of gas suction, at this time, the root and nipple of the patient's breast will be limited by adsorption, releasing the pressure on the upper movable plate 22, and the coil spring 25 will reset under its own elastic action, so that the lower arc-shaped shell 11 and the upper fan-shaped shell 12 will move away from each other, so that the breast is in a straight state, and the area between the lower arc-shaped shell 11 and the upper fan-shaped shell 12 is exposed, thereby achieving the positioning effect of the breast.
