Description

Technical Field

[0001] This invention relates to the field of minimally invasive breast excision surgery technology, and in particular to a smart pillow specifically designed for use during minimally invasive breast excision surgery. Background Technology

[0002] Minimally invasive breast excision surgery includes a preparation stage, a surgical stage, and a recovery stage. The surgical stage involves a small incision made in the skin of the affected breast under ultrasound or mammography stereotactic guidance, using a combination of vacuum suction and excision. A probe is inserted to the breast lump, and the lump is completely removed using negative pressure suction and excision. The surgery is short, and patients can go home immediately afterward. There is minimal bleeding during the procedure, only a very small incision, and no scarring after surgery, resulting in minimal trauma for the patient.

[0003] During the recovery phase of minimally invasive breast excision surgery, a pillow is often placed under the patient's arm to keep it above heart level, thus preventing or reducing edema in the affected upper limb. The height and angle of elevation should be determined based on the doctor's advice. However, most existing pillows used for minimally invasive breast excision surgery are ordinary medical pillows with a fixed height, requiring stacking to elevate the affected limb. They also cannot accurately adapt to different patients, resulting in low applicability. Therefore, we propose a smart pillow specifically designed for minimally invasive breast excision surgery. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a special intelligent pillow for breast minimally invasive excision surgery, so as to solve the technical problem of low applicability of pillows used in current breast minimally invasive excision surgery.

[0005] To achieve the purpose of this invention, the technical solution adopted by this invention is as follows: design a special intelligent pillow for breast minimally invasive excision surgery, including a U-shaped base, a lifting mechanism, a pillow mechanism and a rotation locking mechanism;

[0006] The lifting mechanism consists of a power unit and a lifting unit. Both the power unit and the lifting unit are mounted on the U-shaped base. The power unit is located within the gap of the lifting unit, and the output end of the power unit is connected to the input end of the lifting unit.

[0007] The cushion mechanism is located inside the U-shaped base cavity. The bottom two ends of the cushion mechanism are rotatably connected to the top two ends of the lifting part through a rotating shaft. An installation cavity is provided inside the cushion mechanism relative to the rotating shaft position.

[0008] The rotary locking mechanism is located within the mounting cavity, and its connecting end extends out of the mounting cavity and is fixedly connected to the rotating shaft. Preferably, the power unit includes two parallel rotating seats, which are fixedly mounted on the bottom end of the U-shaped base. One rotating seat has a motor A at its end away from the other rotating seat, and the motor A is fixedly connected to the U-shaped base. A lead screw is arranged between the two rotating seats, with both ends of the lead screw rotatably connected to the two rotating seats respectively. The end of the lead screw near the motor A passes through the rotating seat and is fixedly connected to the output shaft of the motor A. A movable block is threaded onto the lead screw, and the bottom end of the movable block is slidably connected to the top end of the U-shaped base.

[0009] Preferably, the lifting unit includes two bottom sliding plates, two top sliding plates, two scissor linkages, and a top column with a chamfered structure;

[0010] The two bottom sliding plates are symmetrically arranged on both sides of the lead screw;

[0011] The two top slide plates are respectively disposed above the two bottom slide plates, and grooves are provided on both the two top slide plates and the two bottom slide plates;

[0012] The scissor link is disposed in the gap between the top slide plate and the corresponding bottom slide plate. The scissor link has four ports. The two ports away from the slide groove are rotatably connected to the top slide plate and the bottom slide plate respectively through a rotating rod. The two ports close to the slide groove are fixedly provided with connecting rods. The two connecting rods are movably connected to the slide groove on the top slide plate and the slide groove on the bottom slide plate respectively. The connecting rod located at the lower end is fixedly connected to the movable block.

[0013] The top column is mounted on the top slide plate, and the two rotating shafts are respectively fixed at both ends of the top column. A cavity is opened at the lower end of the top column, and the two ends of the top of the cavity are respectively fixedly connected to the two top slide plates.

[0014] Preferably, the cushion mechanism includes a mounting block disposed in the cavity of the U-shaped base, an adaptation groove is provided on one side, two rotating shafts are rotatably connected at both ends of the adaptation groove, the mounting cavity is provided in the mounting block relative to the position of the rotating shafts, and two arc-shaped rotating grooves A are symmetrically provided at the top of the mounting block, each rotating groove A being movably provided with a placement component.

[0015] Preferably, the placement assembly includes two segmental pillars A, four segmental pillars B, and eight segmental pillars C;

[0016] The segmental column A is disposed on the rotating groove A, and a rotating strip A is fixed on the outer edge surface of the segmental column A. The rotating strip A is movably connected to the rotating groove A, and two rotating grooves B are symmetrically opened at the top of the segmental column A.

[0017] The segmental column B is disposed on the rotating groove B, and a rotating strip C is fixed on the outer edge surface of the segmental column B. The rotating strip C is movably connected to the rotating groove B, and two rotating grooves C are symmetrically opened at the top of the segmental column B.

[0018] The segmental column C is disposed on the rotating groove C, and a rotating strip D is fixed on the outer edge surface of the segmental column C. The rotating strip D is movably connected to the rotating groove C, and the eight segmental columns C form a variable placement cavity.

[0019] Preferably, the mounting block, the segmental column A, the segmental column B, and the segmental column C all have concave cross-sections.

[0020] Preferably, the cushion mechanism further includes a soft pad, the soft pad having a hollow interior forming an air cavity, both ends of the soft pad being wavy, and eight connecting blocks fixedly disposed at the bottom of the soft pad relative to the positions of the eight segmental columns C, the bottom ends of the eight connecting blocks being fixedly connected to the top ends of the eight segmental columns C one by one.

[0021] Preferably, the rotary locking mechanism includes a connecting shaft A, two connecting shafts B, and a micro motor B. The connecting shaft A is rotatably disposed on the upper part of the mounting cavity near the rotating shaft. The end of the connecting shaft A near the rotating shaft extends out of the mounting cavity and is fixedly connected to the rotating shaft. A gear is fixedly mounted on the connecting shaft A. The two connecting shafts B are symmetrically disposed on the lower part of the mounting cavity near the rotating shaft. A locking rod is rotatably mounted on the connecting shaft B. A toothed groove is formed at the top of the locking rod, and the toothed groove meshes with the gear. The locking rod is elastically connected to the side wall of the mounting cavity by a spring. The micro motor B is fixedly disposed in the mounting cavity away from the rotating shaft at a gap position relative to the two locking rods. A connecting shaft C is fixedly mounted on the output bearing of the micro motor B, and a protrusion is fixedly mounted on the connecting shaft C.

[0022] The cross-section of the protrusion has an elliptical structure.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This invention, by setting up a U-shaped base, a lifting mechanism, a cushion mechanism, and a rotation locking mechanism, allows the patient to place their arm on the cushion mechanism. The power unit of the lifting mechanism provides power so that the lifting unit can move the cushion mechanism to an appropriate position when it is raised or lowered. The bottom of the cushion mechanism and the top of the lifting unit are connected by a pivot, allowing the cushion mechanism to rotate to an appropriate angle so that the patient's arm is comfortably placed. The rotation locking mechanism rotates and locks the cushion mechanism, so that the cushion mechanism can better support the patient's arm. It has high applicability and solves the technical problem of low applicability of cushions in current minimally invasive breast excision surgery.

[0025] 2. By specifically configuring the lifting mechanism, the present invention sets the power unit as a lead screw structure with an automatic locking function, and sets the lifting unit as a scissor linkage structure, making the structure compact, saving space, and reducing the minimum height of the device.

[0026] 3. By specifically designing the placement components, this invention allows the patient's arm to be placed in a variable placement cavity formed by eight segmental pillars C. The force exerted by the patient's arm on the eight segmental pillars C allows the segmental pillars A, four segmental pillars B, and eight segmental pillars C to rotate freely. The segmental pillars C can automatically conform to the patient's arm and provide support, making it suitable for patients with different arm sizes and improving the applicability of this device.

[0027] 4. By setting the mounting block, the segmental columns A, B, and C to all have concave cross-sections, the present invention enhances the variable space of the placement cavity enclosed by the eight segmental columns C, so that the placement cavity enclosed by the eight segmental columns C can support not only the back of the patient's arm, but also the part of the patient's arm.

[0028] 5. By setting both ends of the soft pad to be wavy, the pressure of the patient's arm on the soft pad when the patient's arm is behind the soft pad causes the soft pad to drive the segmental column A, the four segmental columns B, and the eight segmental columns C to rotate freely. At this time, the soft pad is easy to deform, and the hollow interior of the soft pad forms an air cavity, making the soft pad even easier to deform and more elastic, making it more comfortable for the patient to place their arm on the soft pad.

[0029] 6. This invention, by setting a rotation locking mechanism, allows the micro motor B to rotate when the patient's arm is raised to a suitable position by the cushion mechanism. This rotation is controlled by an external control mechanism, which in turn drives the connecting shaft C and the protrusion to rotate. Under the elastic force of the spring, the contact points between the protrusion and the two locking rods change from the original wide ends to the narrow ends. The two locking rods move closer together, and the toothed grooves at the top of the two locking rods mesh with the gears, preventing the gears from rotating. This indirectly prevents the mounting block from rotating relative to the rotating shaft, thus preventing the entire cushion mechanism from rotating and providing better support for the patient's arm.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1:

[0049] A smart pillow specifically designed for use during minimally invasive breast excision surgery, see [link / reference]. Figures 1 to 11 It includes a U-shaped base 1, a lifting mechanism 2, a cushion mechanism 5, and a rotating locking mechanism 8;

[0050] Specifically, the lifting mechanism 2 consists of a power unit 3 and a lifting unit 4. Both the power unit 3 and the lifting unit 4 are mounted on the U-shaped base 1. The power unit 3 is located within the gap of the lifting unit 4, and the output end of the power unit 3 is connected to the input end of the lifting unit 4.

[0051] The power unit 3 includes two parallel rotating seats 31, which are fixed to the bottom of the U-shaped base 1. A motor A32 is mounted on the end of one rotating seat 31 away from the other, and the motor A32 is fixedly connected to the U-shaped base 1. A lead screw 33 is spaced between the two rotating seats 31, with both ends rotatably connected to the two rotating seats 31. The end of the lead screw 33 near the motor A32 passes through the rotating seat 31 and is fixedly connected to the output shaft of the motor A32. A movable block 34 is threaded onto the lead screw 33, and the bottom end of the movable block 34 is slidably connected to the top end of the U-shaped base 1. This invention, with the same arrangement as described above, allows the motor A32 to be controlled by an external control mechanism. The output shaft of the motor A32 drives the lead screw 33 to rotate around the rotating seat 31. The bottom end of the movable block 34 is prevented from rotating by the force exerted by the top end of the U-shaped base 1, causing the movable block 34 to move along the lead screw 33 and slide relative to the top end of the base 1. The movable block 34 then drives the connecting rod 46 to move along the slide groove 45.

[0052] The lifting unit 4 includes two bottom sliding plates 41, two top sliding plates 42, two scissor linkages 43, and a top column 44 with a chamfered structure;

[0053] Two bottom sliding plates 41 are symmetrically arranged on both sides of the lead screw 33;

[0054] Two top slide plates 42 are respectively positioned above two bottom slide plates 41, and grooves 45 are provided on both the two top slide plates 42 and the two bottom slide plates 41.

[0055] The scissor link 43 is located in the gap between the top slide plate 42 and the corresponding bottom slide plate 41. The scissor link 43 has four ports. The two ports on the side away from the slide groove 45 are rotatably connected to the top slide plate 42 and the bottom slide plate 41 respectively through the rotating rod. The two ports on the side close to the slide groove 45 are fixedly provided with connecting rods 46. The two connecting rods 46 are movably connected to the slide groove 45 on the top slide plate 42 and the slide groove 45 on the bottom slide plate 41 respectively. The connecting rod 46 at the lower end is fixedly connected to the movable block 34.

[0056] The top column 44 is mounted on the top slide plate 42, and two rotating shafts 6 are fixed to both ends of the top column 44. A cavity 47 is formed at the lower end of the top column 44, and the two ends of the top of the cavity 47 are fixedly connected to the two top slide plates 42. Through this arrangement, the movable block 34 can drive the connecting rod 46 to move along the slide groove 45, causing the rod body connected to the scissor link 43 and the connecting rod 46 to rotate relative to the connecting rod 46. This causes the overall height of the scissor link 43 to increase or decrease, thus raising or lowering the top column 44. By specifically configuring the lifting mechanism 2, the power unit 3 is set as a lead screw structure with an automatic locking function, and the lifting unit 4 is set as a scissor link structure, resulting in a compact structure, saving space, and reducing the minimum height of the device.

[0057] Furthermore, the pillow mechanism 5 is located inside the cavity of the U-shaped base 1. The bottom ends of the pillow mechanism 5 are rotatably connected to the top ends of the lifting part 4 via rotating shafts 6. The pillow mechanism 5 includes a mounting block 51, which is located inside the cavity of the U-shaped base 1. An adaptation groove 52 is provided on one side, and two rotating shafts 6 are rotatably connected at both ends of the adaptation groove 52. The mounting cavity 7 is located inside the mounting block 51 relative to the position of the rotating shafts 6. The top of the mounting block 51 has two arc-shaped rotating grooves A53 with a symmetrical structure. Placement components 54 are movably provided on each of the rotating grooves A53.

[0058] The placement component 54 includes two segmental pillars A541, four segmental pillars B544, and eight segmental pillars C547;

[0059] A segmental column A541 is provided on a rotating groove A53. A rotating bar A542 is fixedly provided on the outer edge surface of the segmental column A541. The rotating bar A542 is movably connected to the rotating groove A53. Two rotating grooves B543 are symmetrically opened at the top of the segmental column A541.

[0060] A segmental column B544 is mounted on a rotating groove B543. A rotating bar C545 is fixedly mounted on the outer edge surface of the segmental column B544. The rotating bar C545 is movably connected to the rotating groove B543. Two rotating grooves C546 are symmetrically opened at the top of the segmental column B544.

[0061] A segmental column C547 is mounted on a rotating groove C546. A rotating bar D548 is fixedly mounted on the outer edge of the segmental column C547. The rotating bar D548 is movably connected to the rotating groove C546. The eight segmental columns C547 form a variable placement cavity. Through the specific design of the placement component 54, this invention allows the patient's arm to exert force on the eight segmental columns C547 after the arm is placed in the variable placement cavity. This force enables the segmental column A541, four segmental columns B544, and eight segmental columns C547 to rotate freely. The segmental columns C547 can automatically conform to the patient's arm and provide support, making this device suitable for patients with different arm sizes and improving its applicability.

[0062] The mounting block 51, segmental pillars A541, B544, and C547 all have concave cross-sections. By designing the mounting block 51, segmental pillars A541, B544, and C547 to have concave cross-sections, this invention enhances the adaptability of the placement cavity formed by the eight segmental pillars C547. This allows the placement cavity to support not only the back of the patient's arm but also the upper part of the arm.

[0063] It is worth noting that the pillow mechanism 5 also includes a soft pad 55. The soft pad 55 has a hollow interior forming an air cavity. Both ends of the soft pad 55 are wavy. Eight connecting blocks 56 are fixedly installed at the bottom of the soft pad 55 relative to the eight segmental columns C547. The bottom ends of the eight connecting blocks 56 are fixedly connected to the top ends of the eight segmental columns C547. By setting both ends of the soft pad 55 to be wavy, the pressure of the patient's arm on the soft pad 55 causes the soft pad 55 to drive the segmental columns A541, four segmental columns B544, and eight segmental columns C547 to rotate freely. At this time, the soft pad 55 is easy to deform. The hollow interior of the soft pad 55 forming an air cavity makes the soft pad 55 even more deformable and elastic, making it more comfortable for the patient's arm to rest on.

[0064] In addition, a mounting cavity 7 is provided in the cushion mechanism 5 at a position relative to the rotating shaft 6; a rotating locking mechanism 8 is located in the mounting cavity 7, with its connecting end extending out of the mounting cavity 7 and fixedly connected to the rotating shaft 6. The rotating locking mechanism 8 includes a connecting shaft A81, two connecting shafts B83, and a micro motor B87. The connecting shaft A81 is rotatably located on the upper part of the mounting cavity 7 near the rotating shaft 6, with the end of the connecting shaft A81 extending out of the mounting cavity 7 and fixedly connected to the rotating shaft 6. A gear 82 is fixed on the connecting shaft A81, and the two connecting shafts B83 are positioned... A symmetrical structure is rotatably mounted on the lower part of the mounting cavity 7 near the rotating shaft 6. A locking rod 84 is rotatably mounted on the connecting shaft B83. The top of the locking rod 84 has a toothed groove 85, which meshes with the gear 82. The locking rod 84 is elastically connected to the side wall of the mounting cavity 7 by a spring 86. The micro motor B87 is fixed at the end of the mounting cavity 7 away from the rotating shaft 6, with a gap between the two locking rods 84. A connecting shaft C88 is fixed on the output bearing of the micro motor B87. A protrusion 89 is fixed on the connecting shaft C88. The protrusion 89 has an elliptical cross-section. This invention, by setting a rotation locking mechanism 8, allows the micro motor B87 to rotate when the patient's arm is raised to a suitable position by the cushion mechanism 5. This rotation is controlled by an external control mechanism, which in turn drives the connecting shaft C88 and the protrusion 89 to rotate. Under the elastic force of the spring 86, the contact points between the protrusion 89 and the two locking rods 84 change from wide ends to narrow ends. The two locking rods 84 move closer together, and the toothed grooves 85 at the top of the two locking rods 84 mesh with the gear 82, preventing the gear 82 from rotating. This indirectly prevents the mounting block 51 from rotating relative to the rotating shaft 6, thus preventing the entire cushion mechanism 5 from rotating and providing better support for the patient's arm.

[0065] This invention, by setting up a U-shaped base 1, a lifting mechanism 2, a cushion mechanism 5, and a rotation locking mechanism 8, allows the patient to place their arm on the cushion mechanism 5. The power unit 3 of the lifting mechanism 2 provides power so that the lifting part 4 can move the cushion mechanism 5 to an appropriate position when it is raised or lowered. The bottom of the cushion mechanism 5 and the top of the lifting part 4 are connected by a pivot 6, allowing the cushion mechanism 5 to rotate to an appropriate angle, making the patient's arm comfortable. The rotation locking mechanism 8 rotates and locks the cushion mechanism 5, allowing it to better support the patient's arm. This invention has high applicability and solves the technical problem of low applicability of cushions in current minimally invasive breast excision surgery.

[0066] Working principle: When using, place this device under the patient's arm, ensuring it is positioned between the shoulder and elbow joints, as indicated by the top column 44. The cushion mechanism 5 provides better support for the arm, and the rotation locking mechanism 8 is in the correct position. Figure 11 In the state shown, the two ends of the elliptical wide portion of the protrusion 89 respectively support the two locking rods 84 to each other, the tooth groove 85 is disengaged from the gear 82, the spring 86 is compressed, the gear 82 can rotate freely, so that the entire cushion mechanism 5 can rotate freely.

[0067] The pressure of the patient's arm on the soft pad 55 causes the soft pad 55 to drive the segmental column A541, the four segmental columns B544, and the eight segmental columns C547 to rotate freely, to a similar state. Figure 9 As shown, elevate and support the patient's arm.

[0068] Motor A32 is controlled by an external control mechanism, causing the output shaft of motor A32 to drive the lead screw 33 to rotate around the rotating base 31. The bottom end of the movable block 34 is unable to rotate due to the force exerted by the top of the U-shaped base 1, causing the movable block 34 to move along the lead screw 33 and slide relative to the top of the base 1. The movable block 34 drives the connecting rod 46 to move along the slide groove 45, causing the rod body connected to the scissor rod 43 and the connecting rod 46 to rotate relative to the connecting rod 46, causing the overall height of the scissor rod 43 to increase, causing the top column 44 to rise and drive the entire pillow mechanism 5 to rise, causing the patient's arm to rotate around the shoulder joint. During this process, the pressure of the patient's arm on the soft pad 55 supports the entire pillow mechanism 5 to rotate around the rotating shaft 6, causing the entire pillow mechanism 5 to tilt, and the angle of the pillow mechanism 5 is consistent with the angle of the patient's arm.

[0069] When the patient's arm is raised to a suitable position by the cushion mechanism 5, the micro motor B87 is rotated by the external control mechanism, which drives the connecting shaft C88 and the protrusion 89 to rotate. This causes the contact points between the protrusion 89 and the two locking rods 84 to change from the original wide ends to the narrow ends under the elastic force of the spring 86. The two locking rods 84 are relatively close, and the toothed grooves 85 at the top of the two locking rods 84 are engaged with the gear 82, preventing the gear 82 from rotating. This indirectly prevents the mounting block 51 from rotating relative to the rotating shaft 6, and the entire cushion mechanism 5 cannot rotate, thus providing better support for the patient's arm.

[0070] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
