Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary instruments. More specifically, it particularly relates to an ergonomic device for supporting a doctor's arm during laparoscopic surgery. Background Art

[0002] Laparoscopic surgery is a modern minimally invasive surgical technique. It uses special optical instruments and devices to enter the human body through small incisions for surgical operations.

[0003] After inserting the laparoscope into the body cavity through the trocar and connecting the light source and the imaging system, the doctor can observe the situation inside the body cavity on the monitor, conduct a comprehensive exploration of the lesion site, and according to the surgical needs, insert various surgical instruments such as grasping forceps, scissors, and electrocoagulation hooks through other trocars. Under the monitoring of the laparoscope, the doctor uses these instruments to perform operations such as separating, cutting, hemostasis, and suturing on the lesion tissue. However, during the operation process, there are the following deficiencies.

[0004] 1. During the entire operation process, the surgeon needs to hold this instrument throughout, and constantly adjust according to the lesion site inside the body cavity. The doctor's arm needs to be suspended in the air for a long time and maintain stable operation, which is prone to muscle fatigue and injury, causing discomfort in the hand and arm.

[0005] 2. With the appearance of muscle fatigue, the hand coordination is also greatly reduced. The originally smooth and natural movements become rigid and slow, resulting in a decrease in the operation accuracy. At the same time, after the surgeon gets tired and takes an interval break and then resumes the operation, it will also increase the operation time. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides an ergonomic device for supporting a doctor's arm during laparoscopic surgery to solve the above problems.

[0007] An ergonomic device for supporting a doctor's arm during laparoscopic surgery includes a wearable bracket base, a strap, and a control box. Two connection components are fixedly installed at the side end of the wearable bracket base. Each connection component includes a sleeve body, a deflection arm, a positioning arm, a rotating seat, and a pivot support plate. At least two pressing components are rotatably installed at the top of each pivot support plate. Each pressing component includes a swing plate and a soft rubber strip. Each soft rubber strip is designed as an inward arc. An extension plate is slidably installed at the side end of each pivot support plate.

[0008] Preferably, a rotating component is fixedly installed at the bottom of each pivot support plate. Each rotating component includes a support shaft, an outer sleeve ring, and a limit button. The bottom end of each support shaft is rotatably connected to the rotating seat. Each limit button is slidably docked on the outside of the outer sleeve ring. A return spring is installed at the end of each limit button;

[0009] At least two pneumatic telescopic rods are fixedly installed inside each of the pivot pallets. A horizontally sliding guide slider is fixedly installed at the top end of each pneumatic telescopic rod. A synchronous base for docking and swinging the swing plate is rotatably installed at the top end of each guide slider. A multi-section telescopic sleeve is fixedly installed at the top end of each synchronous base;

[0010] Sliding frames for driving the swing plate to swing are slidably installed at both side ends of each pivot pallet. At least two ripple friction plates with a wave design are provided at the side ends of each sliding frame. The top end of each ripple friction plate rubs against the guide slider.

[0011] Preferably, turntables for driving the sliding frames to slide are rotatably installed at both side ends of each pivot pallet. A support swing arm docked with the sliding frame is rotatably installed on the outer side of each turntable. The end of each turntable is connected to the output shaft;

[0012] Two guide covers for docking the pivot pallets are fixedly installed at the side ends of each extension plate. A rotary push rod for driving the extension plate to move is rotatably installed at the side end of each pivot pallet. A rotatably docked screw sleeve is fixedly installed at the side end of each extension plate;

[0013] A sphere for docking the sleeve body is fixedly installed at the end of each deflection support arm. An airbag pad that fits the sphere is provided inside each sleeve body.

[0014] Preferably, the inside of each airbag pad is designed to be hollow. A joint communicating with the airbag pad is provided on the outer side of each sleeve body. Each joint is connected to a pipeline for conveying air;

[0015] A card slot for docking the support shaft is opened at the top end of each rotating seat. There are multiple positioning holes for docking the rotating seat inside the card slot;

[0016] A soft wing plate is fixedly installed at the top end of each pivot pallet. A holding soft plate is fixedly installed at the top end of each pivot pallet. The top end of each holding soft plate is higher than the soft wing plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, by pulling the strap, one end of the strap is disengaged from the inside of the wearable bracket base. By moving the wearable bracket base and passing through the notch at the side end of the wearable bracket base, the wearable bracket base is worn on the waist and abdomen of the doctor. Then, by passing one end of the strap through the inside of the wearable bracket base and tightening the strap, the inner side of the wearable bracket base is tightened, and the wearable bracket base is fixed on the doctor's body. With the multi-angle adjustment ability of the deflection arm and the positioning arm, no matter whether the uterus is in the anterior position, posterior position or horizontal position during the laparoscopic surgery, when the doctor adjusts the instrument according to the lesion site in the uterine cavity, the device can flexibly adapt and continuously provide stable support. At the same time, since the wearable bracket base is worn on the doctor's body, it does not interfere with the doctor's surgical actions.

[0019] In the present invention, by pulling the deflection arm, the deflection arm rotates inside the sleeve body, so that the deflection angle of the deflection arm and the positioning arm can be adjusted. At the same time, the rotating seat rotates at the top of the positioning arm, driving the pivot tray to adjust the tilt angle at the top of the positioning arm. When the arm is tilted, the deflection arm and the positioning arm can also be adjusted to place the pivot tray under the arm, and the pivot tray plays a role in supporting the arm, avoiding the fatigue of the arm in the suspended operation, and enabling the doctor to operate more easily and accurately during the surgery.

[0020] In the present invention, by pushing the top of the guide slider, the guide slider slides inside the pivot tray. At the same time, the movement of the guide slider drives the synchronous base to tilt and deflect at the top of the guide slider. One end of the telescopic sleeve is connected to the swing plate. The guide slider pulls the telescopic sleeve to expand and contract through the guide slider, and at the same time drives the swing plate to deflect, so that the swing plate drives the soft rubber strip to squeeze the side of the arm. The soft rubber strip can moderately clamp the arm according to the position and movement of the doctor's arm, effectively restricting the unnecessary displacement of the arm during the operation, and at the same time dispersing the pressure and reducing the pressure on the doctor's shoulder, elbow and wrist joints.

[0021] In the present invention, due to the wavy design of the ripple friction plate, the friction between the guide slider and the ripple friction plate pushes the guide slider to move different distances inside the pivot tray. Through the reciprocating sliding of the carriage, the swing plate continuously swings at the top of the pivot tray, and the reciprocating swing of the soft rubber strip can play a certain role in massaging and relaxing the arm muscles, promoting blood circulation in the arm, dispersing muscle pressure and effectively relieving muscle fatigue.

[0022] In the present invention, by pulling the deflection support arm, the deflection support arm drives the sphere to rotate inside the sleeve body. The ball sleeve structure allows the sphere to rotate and swing in multiple directions inside the sleeve body, realizing multi-angle movement. Air is input into the airbag pad through the joint, and the volume of the airbag pad is expanded by the air, enabling the airbag pad to quickly squeeze and position the sphere. It can achieve quick limiting without generating excessive impact force, and at the same time has a good buffering effect to protect the deflection support arm and the positioning support arm.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0033] Please refer to Figure 1 - Figure 8 , the present invention provides an ergonomic device for supporting a doctor's arm during laparoscopic surgery, including a wearable bracket base 11, a strap 12 and a control box 13. Two connecting components are fixedly installed at the side end of the wearable bracket base 11. Each connecting component includes a sleeve body 14, a deflecting arm 18, a positioning arm 19, a rotating seat 21 and a pivoting support plate 22. At least two pressing components are rotatably installed at the top of each pivoting support plate 22. Each pressing component includes a swinging plate 27 and a soft rubber strip 28. Each soft rubber strip 28 is designed as an inward arc. An extension plate 34 is slidably installed at the side end of each pivoting support plate 22. By pulling the deflecting arm 18, the deflecting arm 18 can be rotated inside the sleeve body 14, and the deflection angles of the deflecting arm 18 and the positioning arm 19 can be adjusted. Two fastening bolts are rotatably installed at the side end of the positioning arm 19 to fix the rotating seat 21 and the deflecting arm 18. At the same time, the rotating seat 21 rotates at the top of the positioning arm 19, driving the pivoting support plate 22 to adjust the inclination angle at the top of the positioning arm 19. When the arm is inclined, the deflecting arm 18 and the positioning arm 19 can also be adjusted to place the pivoting support plate 22 under the arm, so as to support the arm through the pivoting support plate 22, avoiding the fatigue of operating with the arm suspended, and enabling the doctor to operate more easily and accurately during the operation;

[0034] By pulling the strap 12, one end of the strap 12 is detached from the inside of the wearable bracket base 11. By moving the wearable bracket base 11, through the notch at the side end of the wearable bracket base 11, the wearable bracket base 11 is worn on the doctor's waist and abdomen. Then, by passing one end of the strap 12 through the inside of the wearable bracket base 11 and tightening the strap 12, the inside of the wearable bracket base 11 is tightened to fix the wearable bracket base 11 on the doctor's body. With the multi-angle adjustment ability of the deflecting arm 18 and the positioning arm 19, during laparoscopic surgery, no matter whether the uterus is in the anterior position, posterior position or horizontal position, when the doctor adjusts the instrument according to the lesion site in the uterine cavity, the device can flexibly adapt and continuously provide stable support. At the same time, since the wearable bracket base 11 is worn on the doctor's body, it does not interfere with the doctor's surgical movements;

[0035] A rotating assembly is fixedly installed at the bottom end of each pivoting support plate 22, and each rotating assembly includes a supporting shaft 38, an outer sleeve ring 39 and a limit button 41. The bottom end of each supporting shaft 38 is rotatably connected to the rotating seat 21, and each limit button 41 slides and docks on the outer side of the outer sleeve ring 39. A return spring is installed at the end of each limit button 41. By applying a thrust to the pivoting support plate 22, the pivoting support plate 22 drives the supporting shaft 38 to rotate at the top end of the rotating seat 21 to adjust the entire deflection angle of the pivoting support plate 22. At the same time, the supporting shaft 38 drives the outer sleeve ring 39 to rotate inside the rotating seat 21, and the outer sleeve ring 39 drives the limit button 41 to slide and rub inside the rotating seat 21. The limit button 41 continuously slides and rubs and rubs on the outer side of the outer sleeve ring 39, and the sliding limit button 41 docks with the inside of the rotating seat 21 to position the angle of the pivoting support plate 22.

[0036] A slot for docking with the support shaft 38 is provided at the top of each rotating seat 21, and a plurality of positioning holes for docking with the rotating seat 21 are provided inside the slot. The top of the limit button 41 is designed in an arc shape, and frictionally enters the inside of the positioning hole to fix the position of the pivot support plate 22;

[0037] At least two pneumatic telescopic rods 29 are fixedly installed inside each pivoting support plate 22, and a horizontally sliding guide slider 31 is fixedly installed on the top of each pneumatic telescopic rod 29. A synchronous base 32 that docks the swing plate 27 is rotatably installed on the top of each guide slider 31. A telescopic sleeve 33 with multiple sections of telescopic is fixedly installed on the top of each synchronous base 32. By pushing the top of the guide slider 31, the guide slider 31 slides inside the pivoting support plate 22. At the same time, the movement of the guide slider 31 drives the synchronous base 32 to tilt and deflect at the top of the guide slider 31. At the same time, one end of the telescopic sleeve 33 is connected to the swing plate 27. The guide slider 31 pulls the telescopic sleeve 33 to extend and retract through the guide slider 31, and drives the swing plate 27 to deflect, so that the swing plate 27 drives the soft rubber strip 28 to squeeze the side end of the arm. The soft rubber strip 28 can appropriately clamp the arm according to the position and movement of the doctor's arm, effectively limit the unnecessary displacement of the arm during the operation, and disperse the pressure at the same time, reducing the pressure on the doctor's shoulder, elbow and wrist joints.

[0038] At both side ends of each pivoting support plate 22, there are slidingly installed carriages 25 that drive the swinging plate 27 to swing. At the side ends of each carriage 25, there are provided at least two corrugated friction plates 26 with a wave design. The top end of each corrugated friction plate 26 rubs against the guiding slider 31. Through the wave design of the corrugated friction plate 26, the friction between the guiding slider 31 and the corrugated friction plate 26 pushes the guiding slider 31 to move different distances inside the pivoting support plate 22. Through the reciprocating sliding of the carriage 25, the swinging plate 27 is driven to continuously swing at the top of the pivoting support plate 22. The reciprocating swing of the soft rubber strip 28 can play a certain role in massaging and relaxing the arm muscles, promoting blood circulation in the arm, dispersing muscle pressure, and effectively relieving muscle fatigue;

[0039] At both side ends of each pivoting support plate 22, there are rotatably installed turntables 23 that drive the carriage 25 to slide. At the outside of each turntable 23, there is rotatably installed a support swing arm 24 that is docked with the carriage 25. The end of each turntable 23 is connected to the output shaft. The rotating turntable 23 drives the support swing arm 24 to swing on the outside. At the same time, the end of the support swing arm 24 is rotatably connected to the carriage 25, pushing the carriage 25 to continuously reciprocate inside the pivoting support plate 22, enabling the top of the corrugated friction plate 26 to continuously rub against the guiding slider 31;

[0040] At the side ends of each extension plate 34, there are fixedly installed two guiding covers 35 that are docked with the pivoting support plate 22. At the side ends of each pivoting support plate 22, there is rotatably installed a rotating push rod 37 that drives the extension plate 34 to move. At the side ends of each extension plate 34, there are fixedly installed rotationally docked screw sleeves 36. By driving the rotation of the rotating push rod 37 through the output shaft, the end of the rotating push rod 37 rotates inside the screw sleeve 36, pushing the extension plate 34 to slide at the side end of the pivoting support plate 22, adjusting the distance between the pivoting support plate 22 and the extension plate 34, and adjusting the support range for the arms of different doctors, increasing the versatility of use;

[0041] At the end of each deflecting support arm 18, there is fixedly installed a sphere 17 that is docked with the sleeve body 14. Inside each sleeve body 14, there is provided an airbag pad 16 that fits the sphere 17. The inside of each airbag pad 16 is designed to be hollow. On the outside of each sleeve body 14, there is provided a joint 15 that communicates with the airbag pad 16. Each joint 15 is connected to a pipeline for conveying air. By pulling the deflecting support arm 18, the deflecting support arm 18 drives the sphere 17 to rotate inside the sleeve body 14. The ball-sleeve structure allows the sphere 17 to rotate and swing in multiple directions inside the sleeve body 14, achieving multi-angle movement. By inputting air into the airbag pad 16 through the joint 15, the volume of the airbag pad 16 is expanded by the air, enabling the airbag pad 16 to quickly squeeze and position the sphere 17, capable of achieving quick limiting without generating excessive impact force, and at the same time having a good buffering effect to protect the deflecting support arm 18 and the positioning support arm 19;

[0042] A soft wing plate 42 is fixedly installed at the top end of each pivot pallet 22, and a supporting soft plate 43 is fixedly installed at the top end of each pivot pallet 22. The top end of each supporting soft plate 43 is higher than the soft wing plate 42. Place the arm on the top end of the soft wing plate 42 and place the wrist on the top end of the supporting soft plate 43 at the same time to form a flat support.

[0043] Working principle:

[0044] In the first step, by tightening the strap 12, the inner side of the wearable bracket base 11 is tightened, and the wearable bracket base 11 is fixed on the doctor's body. With the multi-angle adjustment ability of the deflection arm 18 and the positioning arm 19, no matter whether the uterus is in the anterior position, posterior position or flat position during the laparoscopic surgery, when the doctor adjusts the instrument according to the lesion site in the uterine cavity, this device can flexibly adapt and continuously provide stable support. At the same time, since the wearable bracket base 11 is worn on the doctor's body, it does not interfere with the doctor's surgical actions.

[0045] By pulling the deflection arm 18, the deflection arm 18 drives the sphere 17 to rotate inside the sleeve body 14. The ball sleeve structure allows the sphere 17 to rotate and swing in multiple directions inside the sleeve body 14, realizing multi-angle movement. The deflection angle of the deflection arm 18 and the positioning arm 19 can be adjusted. At the same time, the rotating seat 21 rotates at the top end of the positioning arm 19, driving the pivot pallet 22 to adjust the inclination angle at the top end of the positioning arm 19. When the arm is inclined, the pivot pallet 22 can also be placed under the arm by adjusting the deflection arm 18 and the positioning arm 19, and the pivot pallet 22 plays a supporting role for the arm, avoiding the fatigue of the arm during suspended operation, so that the doctor can operate more easily and accurately during the surgery. A micro air pump is installed inside the control box 13, and gas is transported to the inside of the joint 15 through a pipeline. Air is input into the airbag pad 16 through the joint 15. The volume of the airbag pad 16 is expanded by the air, and the airbag pad 16 quickly squeezes and positions the sphere 17, which can achieve quick limiting without generating too much impact force, and at the same time has a good buffering effect to protect the deflection arm 18 and the positioning arm 19.

[0046] In the second step, by pushing the top end of the guiding slider 31, the guiding slider 31 slides inside the pivoting support plate 22. Meanwhile, as the guiding slider 31 moves, it drives the synchronous base 32 to tilt and deflect at the top end of the guiding slider 31. At the same time, one end of the telescopic sleeve 33 is connected to the swing plate 27. The guiding slider 31 pulls the telescopic sleeve 33 to expand and contract through the guiding slider 31, and simultaneously drives the swing plate 27 to deflect, enabling the swing plate 27 to drive the flexible rubber strip 28 to squeeze the side end of the arm. The flexible rubber strip 28 can moderately clamp the arm according to the position and movement of the doctor's arm, effectively restricting unnecessary displacement of the arm during the operation, and at the same time dispersing the pressure to relieve the pressure on the doctor's shoulder, elbow and wrist joints. Through the reciprocating sliding of the carriage 25, it drives the swing plate 27 to continuously swing at the top end of the pivoting support plate 22. The reciprocating swing of the flexible rubber strip 28 can play a certain role in massaging and relaxing the arm muscles, promoting blood circulation in the arm, dispersing muscle pressure, and effectively relieving muscle fatigue.

[0047] By applying a thrust to the pivoting support plate 22, the pivoting support plate 22 drives the support shaft 38 to rotate at the top end of the rotating base 21, adjusting the entire deflection angle of the pivoting support plate 22. At the same time, the support shaft 38 drives the outer sleeve ring 39 to rotate inside the rotating base 21, and the outer sleeve ring 39 drives the limit button 41 to frictionally slide inside the rotating base 21. By continuously frictionally sliding the limit button 41 on the outside of the outer sleeve ring 39, the sliding limit button 41 abuts against the inside of the rotating base 21 to position the angle of the pivoting support plate 22. By driving the rotation of the rotating push rod 37 through the output shaft, the end of the rotating push rod 37 rotates inside the screwed sleeve 36, pushing the extension plate 34 to slide at the side end of the pivoting support plate 22, adjusting the distance between the pivoting support plate 22 and the extension plate 34, adjusting the support range for the arms of different doctors, and increasing the versatility of use.

Many modifications and variations are obvious to those of ordinary skill in the art.
