Description

Technical Field

[0001] The invention relates to the technical field of breast augmentation, in particular to a drainage tube placement auxiliary device for breast augmentation. Background Art

[0002] In breast augmentation surgery on the human body, the axillary approach is commonly used. An incision is made at the top of the armpit, and tools such as lifters and electric knives are inserted into the incision to peel off the muscle tissue and extend it to the position of the pectoralis major muscle. After peeling off a cavity in the pectoralis major muscle, the prosthesis can be implanted into the cavity of the pectoralis major muscle through the incision. Because the surgery itself will inevitably damage the body, after the surgery, a lot of fluid will inevitably be secreted in the cavity where the prosthesis is located. If it is not discharged in time, it is easy to become inflamed. Therefore, in order to be able to discharge the accumulated fluid from the body in time, a drainage tube needs to be inserted into the body after the operation, and the drainage tube is arranged along the edge of the cavity and surrounds the prosthesis. In this way, the accumulated fluid at various positions in the cavity can flow into the drainage tube and eventually be discharged from the body.

[0003] However, currently when inserting the drainage tube, the doctor can only hold the drainage tube in his hand, insert one end of the drainage tube from the incision into the body, and insert it along the stripped channel toward the pectoralis major muscle. When the drainage tube is inserted into the cavity of the pectoralis major muscle, the doctor can only make the drainage tube turn by feel so that it can be wrapped around the prosthesis. This operation method has many uncertain factors, and the drainage tube can easily shift during the insertion process. It is very difficult for the doctor to operate. Once the position of the drainage tube shifts, the doctor can only pull out the drainage tube and reinsert it, which will undoubtedly increase the patient's pain.

[0004] Therefore, there is a need for an auxiliary device that can quickly, conveniently and safely deliver the drainage tube into the body and complete the surrounding placement. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See attached Figure 1-8 , a drainage tube placement auxiliary device for breast augmentation, comprising a long axis 1, a control mechanism is installed at one end of the long axis 1 and a pull ring 15 is fixed at the other end; a driving mechanism is also arranged on the long axis 1, and the control mechanism is transmission-connected with the driving mechanism;

[0029] The control mechanism includes a first support rod 2 symmetrically hinged on the peripheral wall of the long axis 1, a second support rod 3 is hinged on the end of the first support rod 2 away from the long axis 1, a sliding sleeve 4 is slidably arranged on the long axis 1, an articulation seat 5 is fixedly connected to the outer wall of the sliding sleeve 4 at positions corresponding to the two second support rods 3, and an end of the second support rod 3 away from the first support rod 2 is hinged to the articulation seat 5; the first support rod 2 and the second support rod 3 are both arc-shaped rods and the concave arc side faces the long axis 1; the sliding sleeve 4 is transmission-connected with the driving mechanism; a drainage tube support plate 6 is fixedly connected to the convex arc side of the first support rod 2 and the second support rod 3, a vacuum component is installed on the concave arc side of the first support rod 2 and the second support rod 3, and a plurality of ventilation holes 7 are opened on the drainage tube support plate 6, and the ventilation holes 7 pass through the first support rod 2 or the second support rod 3 and are connected to the vacuum component.

[0030] The length of the long axis 1 needs to ensure that it can extend from the axillary incision to the position of the pectoralis major muscle and have enough spare length for the doctor to operate the driving mechanism; the width of the pull ring 15 needs to be able to accommodate two or three fingers, which makes it easier for the doctor to push and pull the long axis 1; the control mechanism can adsorb the drainage tube 22, or detach the drainage tube 22, and drive the drainage tube 22 to move at the same time, and the driving mechanism can change the shape of the control mechanism, thereby changing the shape of the drainage tube 22.

[0031] The two first support rods 2 and the two second support rods 3 can together form a circle, that is, the first support rod 2 and the second support rod 3 are both quarter-circular arcs, and the size of the circle formed by them is adapted to the size of the cavity peeled off at the pectoralis major muscle during breast augmentation; when the driving mechanism moves in a direction away from the pull ring 15, the sliding sleeve 4 will also follow the movement and squeeze the second support rod 3, and the ends of the second support rod 3 and the first support rod 2 that are away from each other will come closer, and there will be a certain angle between the two, so that the figure formed by the two first support rods 2 and the two second support rods 3 is closer to a circle; when the driving mechanism moves in a direction close to the pull ring 15, the sliding sleeve 4 will also follow the movement, and the distance between the ends of the second support rod 3 and the first support rod 2 that are away from each other will increase, and the first support rod 2 and the second support rod 3 on the same side will be closer to the major axis 1, and the overall width will be reduced, making it convenient to extend into the body from the incision and enter the cavity of the pectoralis major muscle. The drainage tube support plate 6 is an arc-shaped long strip structure, which is compatible with the first support rod 2 and the second support rod 3, but is slightly shorter than the first support rod 2 and the second support rod 3. The drainage tube support plate 6 is set close to the first support rod 2 or the second support rod 3 at any position. The interface of the drainage tube support plate 6 is also curved, approximately C-shaped, with the opening side facing the convex arc side of the drainage tube support plate 6, so that the drainage tube 22 can be better adsorbed; when the vacuum component is started, the gas inside itself and the vent 7 can be drawn away to form a vacuum environment. At this time, the drainage tube 22 can be adsorbed on the drainage tube support plate 6. When the vacuum component stops working, its own interior and the vent 7 will be refilled with gas, and the adsorption function will be lost, and the drainage tube 22 will be detached from the drainage tube support plate 6.

[0032] In another embodiment, the first support rod 2 and the second support rod 3 may also be one-fifth of a circle arc or one-sixth of a circle arc, as long as they can together form an approximate circle.

[0033] To further optimize the solution, the vacuum assembly includes a first air pipe 8 fixedly connected to the concave side of the first support rod 2 and a second air pipe 9 fixedly connected to the concave side of the second support rod 3. The first air pipe 8 and the second air pipe 9 are connected via a first negative pressure hose 10, and the ends of the two first air pipes 8 away from the second air pipe 9 are connected via a second negative pressure hose 11; the end of any second air pipe 9 away from the first air pipe 8 is connected to an air guide pipe 13 fixedly connected to the driving mechanism via a third negative pressure hose 12, and the air guide pipe 13 can be connected to an external vacuum pump, and the end of the other second air pipe 9 away from the first air pipe 8 is sealed.

[0034] Because the first support rod 2 and the second support rod 3 are hinged and can rotate, the first air tube 8 and the second air tube 9 need to be connected by a hose and need to be able to withstand negative pressure; the first air tube 8 and the second air tube 9 are curved tubes with the same curvature as the first support rod 2 and the second support rod 3, respectively. Any position of the first air tube 8 is set close to the first support rod 2, and any position of the second air tube 9 is set close to the second support rod 3; after the external vacuum pump (not shown in the figure) is started, the gas in the first support rod 2, the second support rod 3 and the vent 7 will be extracted, the air pressure will be reduced, suction will be generated, and the drainage tube 22 will be adsorbed. After the vacuum pump stops, the first support rod 2, the second support rod 3 and the vent 7 will be filled with gas again, the air pressure will return to normal, and suction will no longer be generated, so the drainage tube 22 will no longer be adsorbed.

[0035] A further optimized solution is that the driving mechanism includes a long cylinder 14 sleeved on the long axis 1, the long cylinder 14 is limited to one side of the sliding sleeve 4 close to the pull ring 15 and is fixedly connected coaxially with the sliding sleeve 4, and a handle 16 is fixedly sleeved on one end of the outer wall of the long cylinder 14 away from the sliding sleeve 4; the air guide tube 13 is fixedly connected to the outer wall of the long cylinder 14 and passes through the handle 16 axially.

[0036] The long tube 14 is slidably arranged on the long axis 1, and the length of the long tube 14 needs to ensure that the handle 16 is outside the body to complete the push-pull operation of the first support rod 2 and the second support rod 3; the operator can hold the pull ring 15 with one hand and hold the handle 16 with the other hand, push and pull the handle 16, which can drive the long tube 14 to slide, and the sliding of the long tube 14 can drive the sliding sleeve 4 to slide, and the sliding sleeve 4 drives the second support rod 3 to move, thereby changing the shape of the figure composed of the two first support rods 2 and the two second support rods 3, so that the shape of the drainage tube 22 can be changed.

[0037] According to a further optimized solution, first valves 17 are installed at both ends of the first air pipe 8 and between two adjacent vent holes 7 ; and second valves 18 are installed at the positions of two adjacent vent holes 7 of the second air pipe 9 .

[0038] The first valve 17 and the second valve 18 are provided mainly to achieve partial vacuum in the first trachea 8 and the second trachea 9, so as to adapt to drainage tubes 22 of different lengths. That is, when the length of the drainage tubes 22 is not enough to contact all the vents 7, the first valve 17 or the second valve 18 in front of the vent 7 is closed, and the vent 7 will be isolated and no longer have adsorption capacity, thereby preventing necessary tissue fluid in the body from being sucked away.

[0039] According to a further optimization scheme, an electric control switch 19 is installed on the handle 16, and the electric control switch 19 is electrically connected to an external vacuum pump.

[0040] The electric control switch 19 can facilitate the user to control the start and stop of the vacuum pump. When the user holds the handle 16, the user can use the thumb to operate the electric control switch 19 to control the start and stop of the vacuum pump.

[0041] According to a further optimization scheme, a first through hole 20 is provided at the end of the long axis 1 at a position corresponding to the second negative pressure hose 11, and the second negative pressure hose 11 is confined in the first through hole 20; a second through hole 21 is provided on the hinged seat 5 at a position corresponding to the third negative pressure hose 12, and the third negative pressure hose 12 is confined in the second through hole 21.

[0042] In order to make the movement of the second negative pressure hose 11 and the third negative pressure hose 12 smoother and more reasonable, a first through hole 20 and a second through hole 21 are opened. The second negative pressure hose 11 passes through the first through hole 20 to connect the two first air pipes 8, and the third negative pressure hose 12 passes through the second through hole 21 to connect the second air pipe 9 and the air guide tube 13.

[0043] When using the present invention, start the external vacuum pump, and then place the drainage tube 22 on the concave side of the drainage tube support plate 6 along the direction of the drainage tube support plate 6. Due to the suction force, the drainage tube 22 will be tightly sucked onto the drainage tube support plate 6. Next, hold the pull ring 15 with one hand and hold the handle 16 with the other hand, and pull the handle 16 in the direction of the pull ring 15. At this time, the first support rod 2 and the second support rod 3 will also move accordingly, and the angle between them and the long axis 1 will become smaller and smaller, so that the overall width of the device will become smaller, and the control mechanism will be in a contracted state, so that it can extend into the muscle tissue from the incision in the armpit. When the end of the long axis 1 extends into the innermost part of the pectoralis major cavity, the handle 16 is pushed away from the pull ring 15. The first support rod 2 and the second support rod 3 will move in the same direction. At this time, the first support rod 2 and the second support rod 3 will also follow the movement, and the angle between them and the long axis 1 will become larger and larger until the two first support rods 2 and the second support rod 3 together form an approximate circle. At this time, the control mechanism is in the expanded state, and the circular structure is adapted to the pectoralis major cavity. At this time, the drainage tube 22 will be tightly attached to the periphery of the pectoralis major cavity. Then turn off the vacuum pump. At this time, the device no longer generates suction on the drainage tube 22, and the drainage tube 22 is separated from the device. Pull the handle 16 again to move in the direction of the pull ring 15. The angle between the first support rod 2 and the second support rod 3 and the long axis 1 will become smaller again, and the overall width will become smaller again. Finally, the entire device can be pulled out of the body, and the placement of the drainage tube 22 is completed. In addition, in this process, a lifter can be used to lift the prosthesis and the upper chest tissue to facilitate the insertion of the device.
