Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary instruments, in particular to an auxiliary device for pulling a skin flap in a breast operation and an operating method thereof. Background Art

[0002] During breast surgery, it is often necessary to perform flap or tissue separation operations on the subcutaneous tissue, chest skin tissue or rib surface. Since the potential separation surface is large and rich in blood vessels, it is relatively difficult. Therefore, the flap or tissue needs to be well pulled to fully expose the target field of view, which is conducive to the progress of the operation.

[0003] During breast surgery, the assistant uses tissue forceps to pull the skin flap. If the operation time is long, the assistant's wrist will become sore and tired due to the arm being suspended for too long, and the assistant needs to be replaced to continue pulling. In addition, when the assistant is pulling the skin flap, the hand will shake, which will cause secondary injury to the patient. Blood will flow into the surgical area, which will affect the doctor's operation and prolong the entire operation.

[0004] To this end, the present invention provides an auxiliary device for pulling a breast surgery flap and an operation method thereof. Summary of the invention

Specific Embodiments

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0035] Such as Figures 1 to 9As shown in the figure, an auxiliary device for breast surgery skin flap traction according to an embodiment of the present invention includes a U-shaped rod 1; a pair of connecting rods 2 are fixedly connected between adjacent side walls of the pair of U-shaped rods 1; a pair of first mouth-shaped blocks 3 are magnetically slidably connected to the outer side wall of the connecting rod 2; a first telescopic rod 4 is fixedly connected to the side wall of the first mouth-shaped block 3; one end of the first telescopic rod 4 is fixedly connected to a second mouth-shaped block 5; a first sliding rod 6 is magnetically slidably connected to the inner side wall of the second mouth-shaped block 5; a clamping member is provided at the bottom of the first sliding rod 6; the clamping member includes an upper clamping plate 11; one end of the first sliding rod 6 is provided with an upper clamping plate 11; a lower clamping plate 14 is movably connected to the upper clamping plate 11, a third mouth-shaped block 7 is magnetically slidably connected to the outer side wall of the connecting rod 2, and the third mouth-shaped block 7 is located between the pair of first mouth-shaped blocks 3; a second telescopic rod 8 is fixedly connected to the side wall of the third mouth-shaped block 7; one end of the second telescopic rod 8 is fixedly connected to a fourth mouth-shaped block 9; a second sliding rod 10 is magnetically slidably connected to the inner side wall of the fourth mouth-shaped block 9; an auxiliary member is provided at one end of the second sliding rod 10; the auxiliary member includes a suction cup 15; one end of the second sliding rod 10 is connected to a suction cup 15. During operation, by sliding the first mouth-shaped block 3 on the connecting rod 2, the first mouth-shaped block 3 drives the second mouth-shaped block 5 on the first telescopic rod 4 to slide, and the first sliding rod 6 slides on the second mouth-shaped block 5, so that the clamping member can move vertically and horizontally. The function of the clamping member is to clamp and traction the skin flap. By sliding the third mouth-shaped block 7 on the connecting rod 2 and the second sliding rod 10 on the fourth mouth-shaped block 9, the auxiliary member can move vertically and horizontally. The function of the auxiliary member is to peel the skin flap from the human body when making an incision at the patient's affected area, so as to facilitate the clamping member to fix and traction the edge of the skin flap. The magnetically slidable connection method means that the sliding surfaces between parts have magnetism, and the parts will not move when sliding and stationary. When traction the skin flap, when the acting force on it reaches a certain level, it can slide, making it more convenient for the operator to operate the device and reducing secondary injuries to the patient during the process of traction the skin flap.

[0036] A long rod 12 is slidably connected to the side wall of the upper composite plate 11, and one end of the long rod 12 penetrates through the upper composite plate 11; one ends of a pair of the long rods 12 are fixedly connected to each other through a connecting plate; a rotating rod 13 is threadedly connected to the side wall of the connecting plate; one end of the rotating rod 13 is rotatably connected to the side wall of the upper composite plate 11; one ends of a pair of the long rods 12 are fixedly connected to the lower composite plate 14. During operation, the rotating rod 13 is threadedly rotated on the upper composite plate 11, so that the rotation of the rotating rod 13 drives the long rod 12 to slide on the upper composite plate 11 through the connecting plate, and then the sliding of the long rod 12 drives the lower composite plate 14 to move. Under the vertical movement adjustment of the first sliding rod 6, the skin flap is positioned on the horizontal plane between the upper composite plate 11 and the lower composite plate 14. Then, due to the telescopic action of the first telescopic rod 4, the upper composite plate 11 and the lower composite plate 14 move to the position of the skin flap. By rotating the rotating rod 13, the lower composite plate 14 moves upward, reducing the distance between the upper composite plate 11 and the lower composite plate 14, clamping and fixing the skin flap. Under the movement adjustment of the first telescopic rod 4 and the first sliding rod 6, the work of traction on the skin flap is completed.

[0037] A square groove is provided inside the second sliding rod 10; a square block 16 is hermetically slidably connected to the side wall of the square groove; one end of the second sliding rod 10 is threadedly connected with a threaded rod 17, and one end of the threaded rod 17 extends into the square groove and is fixedly connected to the side wall of the square block 16; one end of the second sliding rod 10 is fixedly connected with a plastic hose 18, and the plastic hose 18 communicates with the square groove; one end of the plastic hose 18 is fixedly connected to the suction cup 15; an adjusting member is provided on the side wall of the second sliding rod 10. During operation, the threaded rod 17 is threadedly rotated on the second sliding rod 10, so that the rotation of the threaded rod 17 drives the square block 16 to slide in the square groove. When the suction cup 15 is attached to the edge of the patient's incision, the square block 16 moves upward in the square groove. Since the square block 16 is hermetically slid in the square groove and the suction cup 15 is attached to the surface of the skin flap to generate a seal, when the square block 16 moves upward, the volume of the air in the square groove increases and the pressure decreases. The suction cup 15 is connected to the square groove through the plastic hose 18, enabling the suction cup 15 to lift the skin flap of the patient's affected area, facilitating the clamping of the skin flap by the upper composite plate 11 and the lower composite plate 14, and changing the previous operation where an assistant needed to use forceps to pick up the skin flap by poking it.

[0038] The adjusting member comprises an annular disk 19; the annular disk 19 is fixedly connected to the side wall of the second sliding rod 10; the side wall of the annular disk 19 is slidably connected to a sliding block 20; the side wall of the sliding block 20 is slidably connected to an adjusting rod 21; one end of the adjusting rod 21 is slidably connected to a chassis 23 through a hinge block 22; the chassis 23 and the second sliding rod 10 are ball-connected through a ball joint rod 24; one end of the plastic hose 18 passes through the chassis 23 and is fixed to the side wall of the suction cup 15, and when working, the adjusting rod 21 is moved on the sliding block The hinge block 22 also slides on the chassis 23, causing the suction cup 15 on the chassis 23 to tilt. When the sliding block 20 slides in a circle on the annular disk 19, the tilt direction of the suction cup 15 can be changed, and the vertical movement of the adjusting rod 21 can change the size of the tilt angle, which facilitates the operation to make the lower surface of the suction cup 15 fit with the skin flap and lift the skin flap.

[0039] The outer side walls of the first sliding rod 6 and the second sliding rod 10 are fixedly connected with a fifth mouth-shaped block 25; a group of adjacent side walls of the fifth mouth-shaped block 25 are provided with a card slot; a group of adjacent side walls of the card slot are placed with a Z-shaped elastic telescopic rod 27; the side walls of the Z-shaped elastic telescopic rod 27 near both ends are provided with slots; the side walls of the fifth mouth-shaped block 25 are provided with a latch 42; the latch 42 matches the slot, and when working, the Z-shaped elastic telescopic rod 27 is placed in the card slot, and the elastic state of the Z-shaped elastic telescopic rod 27 when it is at rest is at its maximum. When the suction cup 15 is adjusted in position, due to the Z-shaped elastic The telescopic rod 27 connects the first sliding rod 6 and the second sliding rod 10 together through the fifth mouth-shaped block 25. When the position of the suction cup 15 is adjusted, the upper closing plate 11 will be driven to move synchronously. The height of the upper closing plate 11 is adjusted to a position higher than the suction cup 15 in advance. When the suction cup 15 sucks up the skin flap, the pin 42 is pulled out on the fifth mouth-shaped block 25. When the Z-shaped elastic telescopic rod 27 is removed, the connection between the first sliding rod 6 and the second sliding rod 10 will be released. At this time, after the first sliding rod 6 is moved downward and adjusted, it can clamp and pull the skin flap sucked up by the suction cup 15, avoiding the operator from adjusting the position of the upper closing plate 11 one by one.

[0040] One end of the first sliding rod 6 is provided with a square groove; the side wall of the square groove is slidably connected with a sliding rod 28; the side wall of the sliding rod 28 is fixedly connected to the bottom of the square groove through a spring; the side wall of the sliding rod 28 is provided with a sliding strip 29 through a rotating member; the side wall of the sliding strip 29 is slidably connected to the side wall of the upper composite plate 11; the side wall of the first sliding rod 6 is provided with a square through groove 31; the square through groove 31 communicates with the square groove; the side wall of the sliding rod 28 is provided with a circular groove; the side wall of the circular groove is slidably connected with a circular block 30; the side wall of the circular block 30 is fixedly connected to the bottom of the circular groove through a spring; a group of symmetrically distributed arc grooves 32 are provided on the groove wall of the square through groove 31; the arc grooves 32 are matched with the circular block 30; one end of the circular block 30 is fixedly connected with a square rod 33. During operation, by pressing the square rod 33, the circular block 30 is driven to slide in the circular groove. When the circular block 30 disengages from the circular groove, without the limitation of the circular block 30 in the circular groove, the sliding rod 28 will slide downward in the square groove under the elastic force of the spring in the square groove, thereby driving the upper composite plate 11 to move downward. Under the action of the Z-shaped elastic telescopic rod 27, when the first sliding rod 6 and the second sliding rod 10 are in a fixed relationship and the height of the upper composite plate 11 is higher than that of the suction cup 15 and this height is the length of the square through groove 31, after releasing the restriction of the square rod 33 and sliding to the bottom, the skin flap will be on the horizontal plane between the upper composite plate 11 and the lower composite plate 14. Then, when the upper composite plate 11 slides on the sliding rod 28 through the sliding strip 29, the skin flap will be between the upper composite plate 11 and the lower composite plate 14, facilitating the clamping of the skin flap by the upper composite plate 11 and the lower composite plate 14.

[0041] The rotating member includes a rotating block 34; an arc groove is provided at the bottom of the sliding rod 28; the groove wall of the arc groove is rotatably connected with a rotating block 34; the side wall of the rotating block 34 is fixedly connected to the side wall of the sliding strip 29; a group of clamping grooves 35 are provided on the outer circular wall of the rotating block 34; the groove wall of the arc groove is slidably connected with an arc block 36; a group of clamping blocks 37 are fixedly connected to the side wall of the arc block 36; the clamping blocks 37 are matched with the clamping grooves 35. During operation, the rotating block 34 rotates in the arc groove, so that the rotation of the rotating block 34 drives the upper composite plate 11 to rotate through the sliding strip 29, enabling the upper composite plate 11 to adjust the vertical angle. When clamping the skin flap, through the movement of the first telescopic rod 4 and the first sliding rod 6, and then the rotating block 34 rotates the upper composite plate 11 for the skin flap, the vertical angle of the skin flap on the patient can be adjusted, avoiding the formation of an angle between the skin flap clamped by the upper composite plate 11 and the remaining skin flap and preventing damage to the skin flap. Then, by inserting the clamping block 37 on the arc block 36 into the clamping groove 35 of the rotating block 34, the rotation of the rotating block 34 can be fixed.

[0042] A guiding groove 38 is provided between the adjacent side walls of a set of the first sliding rods 6 and the second sliding rods 10; an isosceles trapezoidal block 39 is slidably connected to the side wall of the guiding groove 38; the side wall of the isosceles trapezoidal block 39 is fixedly connected to the side wall of the guiding groove 38 through a spring; clamping through grooves 40 are provided on the adjacent side walls of the second square-shaped block 5 and the fourth square-shaped block 9; the clamping through grooves 40 are matched with the isosceles trapezoidal block 39. During operation, when the isosceles trapezoidal block 39 slides in the guiding groove 38 and the first sliding rods 6 and the second sliding rods 10 slide on the second square-shaped block 5 and the fourth square-shaped block 9, the isosceles trapezoidal block 39 will enter the clamping through groove 40 under the elastic force of the spring. However, when the first sliding rods 6 and the second sliding rods 10 continue to move, the trapezoidal surface of the isosceles trapezoidal block 39 will contact the groove wall of the clamping through groove 40, causing the isosceles trapezoidal block 39 to be squeezed back into the guiding groove 38, so that the first sliding rods 6 and the second sliding rods 10 will pause during each slide. When the Z-shaped elastic telescopic rod 27 is placed into the card slot of the fifth square-shaped block 25, when the operator slides the first sliding rods 6 and the second sliding rods 10, the isosceles trapezoidal block 39 can be used for positioning the positions of the first sliding rods 6 and the second sliding rods 10 on the second square-shaped block 5 and the fourth square-shaped block 9, enabling a set of fifth square-shaped blocks 25 to be on the same horizontal plane, playing an auxiliary positioning role.

[0043] A set of air permeable grooves 41 are provided on the side walls of the upper composite plate 11 and the lower composite plate 14. During operation, through the air permeable holes on the upper composite plate 11 and the lower composite plate 14, the skin clamped between the upper composite plate 11 and the lower composite plate 14 can be ventilated, reducing the pressing area of the upper composite plate 11 and the lower composite plate 14 on the skin flap.

[0044] As Figure 10 shown, an operation method of an auxiliary device for breast surgery skin flap traction is as follows:

[0045] S1: Place a pair of U-shaped rods 1 on both sides of the patient's body. Through the doctor's adjustment of the second sliding rods 10 and the second telescopic rods 8, place the suction cups 15 vertically at the edges of the patient's breast surgery incisions, and adjust the inclination of the suction cups 15 through the adjusting parts to facilitate fitting the patient's skin and then sucking up the skin flap.

[0046] S2: After synchronously moving the upper composite plate 11 and the suction cups 15, the skin flap will be between the upper composite plate 11 and the lower composite plate 14. Control the distance between the lower composite plate 14 and the upper composite plate 11 to narrow and clamp the skin flap.

[0047] S3: Through the telescopic movement of the first telescopic rods 4 and the vertical movement of the first sliding rods 6, traction is applied to the skin flap between the upper composite plate 11 and the lower composite plate 14, and the vertical angle of traction on the skin flap is changed under the action of the rotating parts.

[0048] Working principle: By the first U-shaped block 3 sliding on the connecting rod 2, the second U-shaped block 5 on the first telescopic rod 4 is driven to slide, and the first sliding rod 6 slides on the second U-shaped block 5, enabling the clamping member to move vertically and horizontally. The function of the clamping member is to clamp and traction the skin flap. By the third U-shaped block 7 sliding on the connecting rod 2 and the second sliding rod 10 sliding on the fourth U-shaped block 9, the auxiliary member can move vertically and horizontally. The function of the auxiliary member is to strip the skin flap from the human body when making an incision at the patient's affected area, facilitating the clamping member to fix and traction the edge of the skin flap. The magnetic sliding connection means that the sliding surfaces between parts have magnetism, and there will be no movement when the parts slide and are static. When traction is applied to the skin flap, it can slide when the acting force on it reaches a certain level, making it more convenient for the operator to operate the device and reducing secondary injuries to the patient during the process of traction the skin flap. By the rotating rod 13 rotating threadedly on the upper base plate 11, the rotation of the rotating rod 13 drives the long rod 12 to slide on the upper base plate 11 through the connecting plate, and then the sliding of the long rod 12 drives the lower base plate 14 to move. Under the vertical movement adjustment of the first sliding rod 6, the skin flap is positioned on the horizontal plane between the upper base plate 11 and the lower base plate 14. Then, due to the telescopic action of the first telescopic rod 4, the upper base plate 11 and the lower base plate 14 move to the position of the skin flap. By rotating the rotating rod 13, the lower base plate 14 moves upward to narrow the distance between the upper base plate 11 and the lower base plate 14, clamping and fixing the skin flap. Under the movement adjustment of the first telescopic rod 4 and the first sliding rod 6, the work of traction the skin flap is completed. By the threaded rod 17 rotating threadedly on the second sliding rod 10, the rotation of the threaded rod 17 drives the square block 16 to slide in the square groove. When the suction cup 15 is attached to the edge of the patient's incision, the square block 16 moves upward in the square groove. Since the square block 16 slides in a sealed manner in the square groove and the suction cup 15 is attached to the surface of the skin flap to generate sealing, when the square block 16 moves upward, the air volume in the square groove increases and the pressure decreases. The suction cup 15 is connected to the square groove through the plastic hose 18, enabling the suction cup 15 to lift the skin flap of the patient's affected area, facilitating the upper base plate 11 and the lower base plate 14 to clamp the skin flap, changing the previous operation where the assistant needs to use forceps to pick up the skin flap by poking. By the adjusting rod 21 moving vertically on the sliding block 20, the hinge block 22 is driven to slide on the chassis 23. When the operator moves the adjusting rod 21 downward, the hinge block 22 on the adjusting rod 21 presses against the chassis 23, and the hinge block 22 also slides on the chassis 23, causing the suction cup 15 on the chassis 23 to tilt. When the sliding block 20 slides annularly on the annular disk 19, the tilting direction of the suction cup 15 can be changed, and the vertical movement of the adjusting rod 21 can change the size of the tilting angle, facilitating the operation to make the lower surface of the suction cup 15 fit the skin flap and lift the skin flap. There is a Z-shaped elastic telescopic rod 27 placed in the card slot, and the elastic force state of the Z-shaped elastic telescopic rod 27 is at its maximum when it is static.When the position of the suction cup 15 is adjusted, since the Z-shaped elastic telescopic rod 27 connects the first sliding rod 6 and the second sliding rod 10 together through the fifth mouth-shaped block 25, when the position of the suction cup 15 is adjusted, the upper closing plate 11 will be driven to move synchronously. The height of the upper closing plate 11 is adjusted to a position higher than the suction cup 15 in advance. When the suction cup 15 sucks up the skin flap, the latch 42 is pulled out on the fifth mouth-shaped block 25. When the Z-shaped elastic telescopic rod 27 is removed, the connection between the first sliding rod 6 and the second sliding rod 10 will be released. At this time, after the first sliding rod 6 is moved downward for adjustment, it can clamp and pull the skin flap sucked up by the suction cup 15, avoiding the operator from adjusting the position of the upper closing plate 11 one by one, and the circular block 30 is driven to slide in the circular groove by pressing the square rod 33. When the circular block 30 is disengaged from the circular groove, the sliding rod 28 will slide downward in the square groove under the elastic force of the spring of the square groove after the circular block 30 is no longer limited in the circular groove, thereby driving the upper closing plate 11 to move downward. Under the action of the Z-shaped elastic telescopic rod 27, when the first sliding rod 6 and the second sliding rod 10 are in a fixed relationship, the height of the upper closing plate 11 is higher than the suction cup 15, and this height is the length of the square through groove 31. After the restriction of the square rod 33 is released and slides to the bottom, the flap will be on the horizontal plane between the upper closing plate 11 and the lower closing plate 14. After the upper closing plate 11 slides on the sliding rod 28 through the sliding bar 29, the flap will be between the upper closing plate 11 and the lower closing plate 14, which is convenient for the upper closing plate 11 and the lower closing plate 14 to clamp the flap. , by rotating the rotating block 34 in the arc groove, the rotation of the rotating block 34 drives the upper closing plate 11 to rotate through the sliding bar 29, so that the upper closing plate 11 can adjust the vertical angle. When clamping the skin flap, the upper closing plate 11 can be rotated by the rotating block 34 through the movement of the first telescopic rod 4 and the first sliding rod 6, so that the vertical angle of the skin flap on the patient can be adjusted to avoid the formation of an angle between the skin flap clamped by the upper closing plate 11 and the remaining skin flap, thereby preventing damage to the skin flap. The locking block 37 on the arc block 36 is inserted into the locking groove 35 of the rotating block 34, so that the rotation of the rotating block 34 can be fixed. The isosceles trapezoidal block 39 slides in the guide groove 38, and the first sliding rod 6 and the second sliding rod 10 are connected between the second mouth-shaped block 5 and the fourth When sliding on the mouth-shaped block 9, the isosceles trapezoidal block 39 will enter the locking groove 40 through the elastic force of the spring, but when the first sliding rod 6 and the second sliding rod 10 continue to move, the trapezoidal surface of the isosceles trapezoidal block 39 will contact the groove wall of the locking groove 40, so that the isosceles trapezoidal block 39 is squeezed back into the guide groove 38, so that the first sliding rod 6 and the second sliding rod 10 will pause every time they slide. When the Z-shaped elastic telescopic rod 27 is placed into the locking groove of the fifth mouth-shaped block 25, the operator can position the first sliding rod 6 and the second sliding rod 10 on the second mouth-shaped block 5 and the fourth mouth-shaped block 9 through the locking effect of the isosceles trapezoidal block 39 when sliding the first sliding rod 6 and the second sliding rod 10, so that a group of fifth mouth-shaped blocks 25 are on the same horizontal plane.It plays a role in assisting positioning. Through the ventilation holes on the upper composite plate 11 and the lower composite plate 14, the skin clamped between the upper composite plate 11 and the lower composite plate 14 can breathe, reducing the pressing area of the upper composite plate 11 and the lower composite plate 14 on the skin flap.
