Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an auxiliary device for liver lobe surgery. Background Technology

[0002] Currently, surgeons, such as hepatobiliary surgeons performing laparoscopic surgeries, need to elevate their operating arms during procedures. This elevated arm must also maintain stability during delicate surgical maneuvers. If the surgery is lengthy, this can cause fatigue and soreness in the surgeon's shoulder and neck muscles, increasing their workload. Most importantly, fatigue can lead to instability in the operating arm, thus affecting the success of the surgery. Summary of the Invention

[0036] This invention proposes an auxiliary device for liver lobe surgery.

[0037] Please refer to the attached document. Figure 1 -Appendix Figure 7In one embodiment of an auxiliary device for liver lobe surgery proposed in this invention, the auxiliary device for liver lobe surgery includes a connecting frame, a connecting box 150, a first rotating shaft 350, a grooved wheel 370, a pull cable 210, a connecting frame 220, a hanging bag 230, and a drive assembly; the connecting frame is used to connect to the ceiling wall of the room (i.e., installed on the inner ceiling wall of the operating room); the connecting box 150 is disposed on the connecting frame; the connecting box 150 has an inner cavity 310; the first rotating shaft 350 is rotatably disposed in the inner cavity 310; the grooved wheel 370 is coaxially connected to the first rotating shaft 350; one end of the pull cable 210 is connected to the grooved wheel 370 and wound around the grooved wheel 370; the connecting box 150 includes components arranged opposite to each other. A top plate (not labeled) and a bottom plate 320; the bottom plate 320 has a through hole 360; the other end of the cable 210 is movably inserted through the through hole 360 ​​to extend out of the connecting box 150; the other end of the cable 210 (i.e., the end of the cable 210 extending out of the connecting box 150, which is the bottom end of the cable 210) is connected to a connecting frame 220; a hanging basket 230 is connected to the end of the connecting frame 220 away from the cable 210; the hanging basket 230 is used for the operator's arm to pass through and to support the operator's arm; a drive assembly is disposed in the connecting box 150; the drive assembly is used to drive the first rotating shaft 350 to rotate, thereby driving the grooved wheel 370 to rotate, thereby driving the cable 210 to rise or fall.

[0038] The auxiliary device for liver surgery proposed in this invention can support the surgeon's operating arm during surgery. In use, the surgeon passes the operating arm through the sling 230 and places it in the sling 230. The sling 230 provides vertical support for the operating arm. Due to the effect of the cable 210, the sling 230 does not hinder the rotation of the operating arm, thus facilitating the surgeon's surgical operation. By supporting the operating arm with the sling 230, the surgeon's shoulder and neck muscles are relieved of fatigue and soreness, reducing the surgeon's burden and preventing instability of the operating arm that may be caused by fatigue, thus ensuring the normal progress of the surgery.

[0039] Furthermore, the aforementioned connecting frame includes a first connecting plate 110, a second connecting plate 120, a first slide rail (not shown), a second slide rail (not shown), and a movable arm 130. Both the first connecting plate 110 and the second connecting plate 120 are used to connect to the inner wall of the roof. The first slide rail is horizontally disposed on the first connecting plate 110; the second slide rail is horizontally disposed on the second connecting plate 120; the first slide rail is parallel to the second slide rail; the movable arm 130 is slidably connected to both the first and second slide rails; the movable arm 130 is perpendicular to the first slide rail; and a connecting box 150 is disposed on the movable arm 130. This arrangement allows the movable arm 130 to move horizontally, thereby adjusting the horizontal position of the connecting box 150 to suit different surgical positions and enhance the applicability of this auxiliary device.

[0040] Meanwhile, the connecting frame also includes a first lead screw 140 and a first motor 180; the first lead screw 140 is rotatably disposed on the side of the first connecting plate 110 away from the second connecting plate 120, and the first lead screw 140 is parallel to the first slide rail; the first motor 180 is disposed on the first connecting plate 110 to drive the first lead screw 140 to rotate; the moving arm 130 has a through-hole for engaging with the first lead screw 140; the first lead screw 140 is engaged with the first threaded hole. By setting the first lead screw 140 and the first motor 180, the horizontal movement of the moving arm 130 is driven more stably.

[0041] In addition, the connecting frame also includes a second lead screw 170, a second motor (not shown), and a third slide rail 190; the third slide rail 190 is horizontally disposed on the moving arm 130 and is perpendicular to the first slide rail; the connecting box 150 is horizontally slidably connected to the third slide rail 190; the second lead screw 170 is rotatably disposed on the moving arm 130 and is parallel to the third slide rail 190; the second motor is disposed on the moving arm 130 for driving the second lead screw 170 to rotate; the connecting box 150 is provided with a connecting block 160; the connecting block 160 has a through-hole for engaging with the second lead screw 170; the second lead screw 170 is engaged with the second threaded hole.

[0042] Specifically, through the above technical solution, the second motor drives the second lead screw 170 to rotate, thereby driving the connecting box 150 to move horizontally relative to the moving arm 130. The direction of movement of the connecting box 150 relative to the moving arm 130 is perpendicular to the direction of movement of the moving arm 130 relative to the first connecting plate 110 and the second connecting plate 120, thereby greatly expanding the movable range of the connecting box 150 to suit different surgical positions and enhancing the applicability of this auxiliary device.

[0043] In addition, a first partition 330 is vertically arranged inside the inner cavity 310; one end of the first rotating shaft 350 is rotatably connected to the inner wall of the inner cavity 310; the other end of the first rotating shaft 350 is rotatably inserted through the first partition 330; the drive assembly includes a second rotating shaft 410, a worm gear 380, a worm 390, and a third motor 530; the worm gear 380 is coaxially connected to the other end of the first rotating shaft 350; the worm gear 380 and the grooved wheel 370 are respectively located on both sides of the first partition 330; the second rotating shaft 410 is rotatably arranged in the inner cavity 310, and the second rotating shaft 410 is perpendicular to the first rotating shaft 350; the second rotating shaft 410 is located on the side of the first partition 330 away from the grooved wheel 370; the worm 390 is coaxially sleeved on the second rotating shaft 410; the worm 390 meshes with the worm gear 380.

[0044] The third motor 530 is disposed on the inner wall of the inner cavity 310; the third motor 530 is used to drive the second rotating shaft 410 to rotate. Through the above technical solution, the structure and function of the drive assembly are improved. Specifically, the third motor 530 drives the second rotating shaft 410 to rotate, thereby driving the worm gear 390 to rotate, which in turn drives the worm wheel 380 to rotate, thereby driving the first rotating shaft 350 to rotate, which in turn drives the grooved wheel 370 to rotate, thus driving the cable 210 to rise or fall, thereby adjusting the vertical height of the sling 230 to suit different surgical positions and surgeons of different heights. By setting the drive structure of the worm wheel 380 and worm gear 390, speed reduction and torque increase can be achieved, and it also has a self-locking capability.

[0045] Meanwhile, the drive assembly also includes a third rotating shaft 450, a first belt 440 pulley 420, a second belt 520 pulley 430, and a first belt 440; the third rotating shaft 450 is rotatably disposed in the inner cavity 310; the third rotating shaft 450 is parallel to the second rotating shaft 410; the first pulley 420 is coaxially sleeved on the second rotating shaft 410, and the second pulley 430 is coaxially sleeved on the third rotating shaft 450; the first belt 440 is tensioned and sleeved between the first pulley 420 and the second pulley 430; and a third motor 530 is used to drive the third rotating shaft 450 to rotate. The above technical solution improves the structure and function of the drive assembly, namely, the third motor 530 drives the third rotating shaft 450 to rotate, thereby driving the second shaft 410 to rotate.

[0046] In addition, as attached Figure 4 As shown, the drive assembly also includes a locking component; the locking component includes a locking disc 540, a long rod 580, a first pressure plate 590, a second pressure plate 610, a first spring 630, and an electromagnet 650; the locking disc 540 is coaxially sleeved on the first rotating shaft 350; the locking disc 540 is located on the side of the grooved wheel 370 opposite to the first partition 330; the inner cavity 310 is vertically provided with a second partition 340; one end of the long rod 580 is connected to the inner wall of the inner cavity 310, and the other end of the long rod 580 is connected to the second partition 340; the long rod 580 is parallel to the first rotating shaft 350; the first A pressure plate 590 is coaxially fixedly sleeved on a long rod 580; a second pressure plate 610 is coaxially slidably sleeved on a long rod 580; the first pressure plate 590 and the second pressure plate 610 are respectively located on both sides of the locking plate 540; a first spring 630 is sleeved on a long rod 580; the first spring 630 is in a compressed state, so that the second pressure plate 610 has a tendency to slide towards the first pressure plate 590, so that the second pressure plate 610 abuts against the locking plate 540; an electromagnet 650 is disposed on a second partition 340, and the electromagnet 650 is used to separate the second pressure plate 610 from the locking plate 540.

[0047] The first pressure plate 590 has a rubber layer (not shown) on the side facing the locking plate 540, and the second pressure plate 610 also has a rubber layer (not shown) on the side facing the locking plate 540.

[0048] Specifically, when it is necessary to lock the first rotating shaft 350 to fix the vertical position of the hanging bag 230, the electromagnet 650 is de-energized and loses its magnetic force. Under the elastic force of the first spring 630, the second pressure plate 610 moves towards the first pressure plate 590, thereby clamping and fixing the locking plate 540 between the first pressure plate 590 and the second pressure plate 610, thereby locking and fixing the locking plate 540 to fix the first rotating shaft 350.

[0049] In addition, the locking components also include a first retaining ring 620 and a contact ring 640; the first retaining ring 620 is fixedly sleeved on the long rod 580, and the first retaining ring 620 is located on the side of the second pressure plate 610 opposite to the first pressure plate 590; one end of the first spring 630 is connected to the first retaining ring 620; the other end of the first spring 630 is connected to the second pressure plate 610; the contact ring 640 is connected to the second pressure plate 610, and the contact ring 640 is located on the side of the first retaining ring 620 opposite to the second pressure plate 610; the contact ring 640 and the long rod 580 share a central axis; the electromagnet 650 is a ring electromagnet 650; the ring electromagnet 650 is disposed on the side of the second partition 340 near the long rod 580; the ring electromagnet 650 is sleeved on the long rod 580; the ring electromagnet 650 is used to attract the contact plate, so that the second pressure plate 610 is separated from the locking plate 540.

[0050] The above technical solution improves the structure and function of the locking component. When locking the locking disc 540 is not required, the electromagnet 650 is energized, thereby attracting the contact ring 640, which in turn separates the second pressure plate 610 from the locking disc 540 (as shown in the attached figure). Figure 4 (As shown).

[0051] Meanwhile, the aforementioned locking components also include a second retaining ring 550, a second spring 570, and a third retaining ring 560; the second retaining ring 550 and the third retaining ring 560 are coaxially fixedly sleeved on the first rotating shaft 350; the second retaining ring 550 and the third retaining ring 560 are respectively located on both sides of the locking disc 540; the second baffle 270 and the first pressure plate 590 are located on the same side of the locking disc 540; the second spring 570 is sleeved on the first rotating shaft 350; one end of the second spring 570 is connected to the second retaining ring 550. The other end of the second spring 570 is connected to the locking disc 540; the locking disc 540 and the first rotating shaft 350 are connected by a spline so that the locking disc 540 can slide axially relative to the first rotating shaft 350; the second spring 570 is in a compressed state so that the locking disc 540 tends to abut against the third retaining ring 560; when the locking disc 540 abuts against the third retaining ring 560, the locking disc 540 and the first pressure plate 590 separate; the elastic force of the first spring 630 is greater than the elastic force of the second spring 570.

[0052] When it is necessary to lock the first rotating shaft 350, the electromagnet 650 loses power and loses its magnetic force. Under the elastic force of the first spring 630, the second pressure plate 610 moves towards the first pressure plate 590, thereby driving the locking plate 540 to slide towards the first pressure plate 590. Finally, the locking plate 540 is clamped and fixed between the first pressure plate 590 and the second pressure plate 610, thereby locking and fixing the locking plate 540 to fix the first rotating shaft 350.

[0053] When locking disc 540 is not required, electromagnet 650 is energized, thereby engaging contact ring 640 and causing second pressure plate 610 to slide away from first pressure plate 590, thus separating second pressure plate 610 from locking disc 540 (as shown in the attached figure). Figure 4 As shown), the locking disc 540 moves towards the third retaining ring 560 under the action of the second spring 570, and the locking disc 540 finally abuts against the third retaining ring 560. At this time, the locking disc 540 does not contact the first pressure plate 590 and the second pressure plate 610, so that the first pressure plate 590 and the second pressure plate 610 do not interfere with the rotation of the locking disc 540.

[0054] In addition, as attached Figures 4-7 As shown, the locking component further includes a rotating sleeve 460, a contact arm 670, a protruding arm 660, a first contact switch 720, a second contact switch 750, a first sleeve 710, a second sleeve 740, a third spring 730, a fourth spring 760, a fourth retaining ring 480, a fifth retaining ring 490, a third pulley 470, a fourth pulley 510, and a second belt 520; the rotating sleeve 460 is rotatably sleeved on the third rotating shaft 450; the fourth retaining ring 480 and the fifth retaining ring 490 are coaxially fixedly sleeved on the third rotating shaft 450; the fourth retaining ring 480 and the fifth retaining ring 490 are respectively located on both sides of the rotating sleeve 460; the two sides of the rotating sleeve 460 are in sliding contact with the fourth retaining ring 480 and the fifth retaining ring 490 respectively; the protruding arm 660 is connected to the third rotating shaft 450; the contact arm 670 is connected to the rotating sleeve 460; the first sleeve 710 and the second sleeve 740 are respectively disposed on both sides of the protruding arm 660. The rotating sleeve 460 and the third rotating shaft 450 share a common central axis.

[0055] The first contact switch 720 is disposed on the first sleeve 710 and extends out of the first sleeve 710; the third spring 730 is disposed on the first sleeve 710 and sleeved on the first contact switch 720; one end of the third spring 730 is connected to the protruding arm 660, the other end of the third spring 730 extends out of the first sleeve 710, and the other end of the third spring 730 is further away from the protruding arm 660 than the first contact switch 720.

[0056] The second contact switch 750 is disposed on the second sleeve 740 and extends out of the second sleeve 740; the fourth spring 760 is disposed on the second sleeve 740 and is sleeved on the second contact switch 750; one end of the fourth spring 760 is connected to the protruding arm 660, the other end of the fourth spring 760 extends out of the second sleeve 740, and the other end of the fourth spring 760 is further away from the protruding arm 660 than the second contact switch 750.

[0057] The third pulley 470 is coaxially fixedly sleeved on the rotating sleeve 460; the fourth pulley 510 is coaxially connected to the output shaft of the third motor 530; the second belt 520 is tensioned and sleeved between the third pulley 470 and the fourth pulley 510; the first contact switch 720 and the second contact switch 750 are electrically connected to the electromagnet 650 respectively through a conductive slip ring (not shown); the contact arm 670 is used to abut against the first sleeve 710 to trigger the first contact switch 720; the contact arm 670 is also used to abut against the second sleeve 740 to trigger the second contact switch 750; specifically, the contact arm 670 includes a first wall 680 and a second wall 690, and the first wall 680 and the second wall 690 are centrally symmetrical about the central axis of the rotating sleeve 460; the first wall 680 is used to abut against the first sleeve 710, and the second wall 690 is used to abut against the second sleeve 740.

[0058] Both the first contact switch 720 and the second contact switch 750 are normally in an untriggered state, and the corresponding electromagnet 650 is not energized at this time. When the first contact switch 720 is triggered, the electromagnet 650 is energized; when the second contact switch 750 is triggered, the electromagnet 650 is energized.

[0059] Through the above technical solution, when the cable 210 needs to be driven to rise, the third motor 530 is activated, which drives the rotating sleeve 460 to rotate via the third pulley 470, the fourth pulley 510, and the second belt 520. The rotating sleeve 460 drives the contact arm 670 to rotate, ultimately causing the first wall 680 of the contact arm 670 to contact the third spring 730 and compress the third spring 730. Then, the first contact switch 720 is triggered, ultimately causing the first wall 680 to abut against the first sleeve 710. After the first contact switch 720 is triggered, the electromagnet 650 is energized, thereby causing the first pressure plate 590 and the second pressure plate 610 to no longer lock. The stop plate 540, because the first wall 680 abuts against the first sleeve 710, causes the rotating sleeve 460 to drive the third rotating shaft 450 to rotate synchronously, thereby driving the second rotating shaft 410 to rotate, and then driving the first rotating shaft 350 to rotate, so as to realize the rise of the cable 210. After the cable 210 rises to the appropriate position, the third motor 530 stops, the rotating sleeve 460 stops rotating, and under the elastic force of the third spring 730, the first wall 680 no longer abuts against the first contact switch 720, the electromagnet 650 is de-energized, so that the first pressure plate 590 and the second pressure plate 610 lock the locking plate 540 to fix the position of the first rotating shaft 350 and the position of the cable 210.

[0060] When the cable 210 needs to be lowered, the third motor 530 is started in reverse. This drives the rotating sleeve 460 to rotate in the opposite direction via the third pulley 470, the fourth pulley 510, and the second belt 520. The rotating sleeve 460 drives the contact arm 670 to rotate, ultimately causing the second wall 690 of the contact arm 670 to contact the fourth spring 760 and compress it. This triggers the second contact switch 750, causing the second wall 690 to abut against the second sleeve 740. After the second contact switch 750 is triggered, the electromagnet 650 is energized, thus preventing the first pressure plate 590 and the second pressure plate 610 from locking the locking plate 540. Because the second wall 690... The second sleeve 740 abuts against the third rotating shaft 450, causing the rotating sleeve 460 to drive the third rotating shaft 450 to rotate synchronously in the opposite direction, thereby driving the second rotating shaft 410 to rotate in the opposite direction, and then driving the first rotating shaft 350 to rotate in the opposite direction, so as to realize the descent of the cable 210. After the cable 210 descends to the appropriate position, the third motor 530 stops, the rotating sleeve 460 stops rotating, and under the elastic force of the fourth spring 760, the second wall 690 no longer abuts against the second contact switch 750, the electromagnet 650 is de-energized, so that the first pressure plate 590 and the second pressure plate 610 lock the locking plate 540 to fix the position of the first rotating shaft 350 and fix the position of the cable 210.

[0061] Meanwhile, as attached Figure 2 and attached Figure 3As shown, the auxiliary device for liver lobe surgery also includes a lifting rod 260, a baffle 270, a stop bar 290, and a fifth spring 280; the connecting frame 220 includes a first horizontal plate 240 and a second horizontal plate 250 facing each other, with the first horizontal plate 240 located above the second horizontal plate; the other end of the cable 210 is connected to the first horizontal plate 240; the lifting rod 260 is axially slidably inserted through the second horizontal plate 250; the end of the lifting rod 260 located inside the connecting frame 220 is connected to the baffle 270; the fifth spring 280 is sleeved on the lifting rod 260, with one end of the fifth spring 280 connected to the second horizontal plate 250 and the other end connected to the baffle 270; the stop bar 290 is vertically connected to the side of the baffle 270 facing the second horizontal plate 250; the stop bar 290 is used to abut against the second horizontal plate 250; the end of the lifting rod 260 extending out of the connecting frame 220 is connected to a hanging bag 230. Through the above technical solution, the sling 230 has vertical elasticity margin, that is, when the surgeon's operating arm is in the sling 230, the surgeon is allowed to make more convenient fine adjustments to the vertical position of the operating arm, making it easier for the surgeon to perform surgical operations.
