Description

Technical Field

[0001] The present invention relates to the field of medical auxiliary instruments, and particularly to an all-terrain robotic arm-assisted surgical operating table. Background Art

[0002] With the continuous development of modern medical technology, as an important means of treating diseases, surgical operations have increasingly high requirements for surgical equipment. Especially in special environments such as field rescue and battlefield medical treatment, the portability, adaptability, and intelligence level of surgical equipment are particularly important. However, existing operating tables are often bulky and complex in structure, and it is difficult to adapt to the complex and changeable terrain conditions in the wild. The terrain conditions in the wild are diverse, including flat grasslands, rugged mountains, muddy wetlands, etc. Traditional operating table designs are often based on a fixed operating room environment, and their structural stability is highly related to the flatness of the ground. In the wild environment, the instability of the ground conditions will cause the operating table to be unable to maintain stability, thereby affecting the accuracy and safety of the operation. At the same time, due to the limitation of the number of personnel, it is often impossible to obtain a complete surgical team, and this will also affect the normal progress of the operation in such a situation.

[0003] In summary, the research and development of an all-terrain robotic arm-assisted surgical operating table has important practical significance and application value. It can not only solve the problem that surgical equipment is difficult to apply in the wild environment, but also provide strong support for surgical operations in special situations such as field rescue and battlefield medical treatment. Summary of the Invention

[0004] The present invention aims to provide an all-terrain robotic arm-assisted surgical operating table, which solves the problems that the existing surgical operating table cannot be applied to the wild terrain environment and the surgical team is not complete.

[0005] To achieve the above object, the technical solution of the present invention is as follows: An all-terrain robotic arm-assisted surgical operating table includes a first bed board. Both sides of the first bed board are provided with sliding grooves. Each sliding groove is slidably connected with a second bed board. Handles are provided at the ends of the two second bed boards. Sleeves are provided on both sides of the first bed board and the second bed board through connecting rods. A first threaded rod is threadedly connected in the sleeve. The end of the first threaded rod is rotatably connected with a roller. A robotic arm is further provided at the end of the sleeve. An opening for the sliding of the connecting rod is penetrated through the sliding groove. A groove is provided on the second bed board. A support board is slidably and sealingly connected in the groove. A positioning component for adjusting the positions of the support board and the second bed board is further provided in the groove.

[0006] Further, the positioning component includes a second threaded rod that is collinear with the connecting rod. A threaded hole that is threadedly connected to the second threaded rod is provided on the second bedplate. A rotating groove is provided in the groove. A cam with one end located in the rotating groove is covered on the second threaded rod. The side wall of the cam abuts against the bottom of the support plate. A spring is provided on the side of the support plate away from the cam. The spring is located in the groove.

[0007] With the above arrangement, the second threaded rod can drive the cam to rotate. After the cam rotates, it can drive the end of the support plate to move, thereby controlling the position of the support plate by means of the cam and the spring, and controlling the positions of the support plate and the second bedplate by the abutment between the support plate and the chute.

[0008] Further, wedge surfaces are provided on both sides of the support plate.

[0009] With the above arrangement, the wedge surfaces are conducive to the smooth entry of the support plate into the chute, improving the adjustment efficiency of this solution.

[0010] Further, a plurality of first limiting grooves are spaced apart on the surface of the support plate. Limiting strips that cooperate with the first limiting grooves are provided on the inner wall of the chute.

[0011] With the above arrangement, the cooperation between the limiting strips and the first limiting grooves is conducive to improving the positioning stability of the second bedplate.

[0012] Further, polygonal second limiting grooves are provided on the side walls of the first bedplate and the second bedplate. A limiting ring that fits the shape of the second limiting groove is embedded in the second limiting groove. The limiting ring covers the connecting rod and is slidably connected to the connecting rod. A tightening nut that abuts against the limiting ring is also threadedly connected to the connecting rod. The connecting rod is rotatably connected to the second limiting groove. A torsion spring is connected between the connecting rod and the second limiting groove.

[0013] With the above arrangement, by rotating the push plate, the restriction of the limiting ring on the second limiting groove can be released, enabling the connecting rod to rotate in the second limiting groove, facilitating movement on different field terrains so that the connecting rod can drive the sleeve and the roller to rotate to quickly pass different obstacles, which is conducive to improving the moving speed and reducing the fatigue of medical staff during the moving process.

[0014] Further, a smooth rod is provided on the lower side of the first threaded rod. An equipment groove is provided on the smooth rod. A driving motor is fixedly connected in the equipment groove. A plurality of spiral blades and support bearings located outside the spiral blades are circumferentially distributed on the output shaft of the driving motor. A plurality of support rods are circumferentially distributed on the outer ring of the support bearing. The ends of all the support rods are jointly connected to the roller.

[0015] With the above settings, the cavity formed by the groove and the support plate can provide buoyancy for this device, and different drive motors are used to drive the spiral blades to rotate to provide a power source for the movement of this device on the water surface. At the same time, the function of steering can be realized by using the switches of different drive motors, breaking through the limitation that this solution can only perform surgeries on different terrains on the road surface, which is beneficial to saving the surgery preparation time.

[0016] Furthermore, an evacuated airbag is fixedly connected to the bottom of the first bedplate. An air tube is connected to the airbag and penetrates through the first bedplate at one end. A one-way valve is provided in the air tube, and a gas plug is hermetically connected to the end of the air tube.

[0017] With the above settings, when it is necessary to transfer this device over a short distance in the water area, the gas plug can be pulled out to allow the airbag to inhale air naturally and inflate, so as to provide greater buoyancy support for this device and maintain the reliability of this solution.

[0018] Furthermore, all the drive motors are commonly electrically connected to a remote controller.

[0019] With the above settings, the control of different drive motors can be realized by means of the remote controller, which is beneficial to only transporting this device in the water area and avoiding the problem of safety accidents.

[0020] Furthermore, when the bottoms of the three rollers are flush, the directions of the rollers on both sides are perpendicular to the direction of the roller in the middle.

[0021] With the above settings, when this device is placed for surgery on a horizontal plane, the inconsistent directions of the rollers are used to hinder the movement of the rollers, which is beneficial to maintaining the stability of this device.

[0022] Compared with the prior art, the beneficial effects of this solution are as follows:

[0023] 1. This solution can adjust the position of the second bedplate through the positioning component and the connecting rod, so that the transfer of all terrains in the wild can be realized by means of the rollers. At the same time, the problem that surgery cannot be performed when the personnel are not complete can be avoided by means of the robotic arm, greatly improving the mobility and practicability of this device in field surgeries.

[0024] 2. When it is necessary to transfer over a short distance in case of encountering a water area, this solution can enable this device to quickly reach the predetermined location through the drive motor and the spiral blade, avoiding the time required to find other equipment to assist in the transfer of this device, which is beneficial to saving the surgery preparation time and winning precious time for the timely treatment of the wounded.

An equipment groove is provided on the lower side of the smooth rod, and a driving motor 8 is fixedly connected in the equipment groove. In this embodiment, the driving motor 8 uses a waterproof motor. All the driving motors 8 are commonly electrically connected to a remote control, and the remote control can be used to control the opening or closing of different driving motors 8. A plurality of spiral blades 9 are circumferentially distributed on the output shaft of the driving motor 8 and a support bearing 10 is located outside the spiral blades 9. The support bearing 10 is located at the end of the output shaft of the driving motor 8. A plurality of support rods 11 are circumferentially distributed on the outer ring of the support bearing 10. In this embodiment, the number of the support rods 11 is three. The ends of all the support rods 11 are commonly connected to a roller 12. The radius of the roller 12 is greater than the distance from the edge of the spiral blade 9 to the center of the output shaft of the driving motor 8. When the bottoms of the three rollers 12 are flush, the directions of the rollers 12 on both sides are perpendicular to the roller 12 in the middle.

[0034] A robotic arm 13 is also bolt - connected to the top of the sleeve 6. In this embodiment, the robotic arm 13 uses an existing product and this solution does not improve it. Openings 14 through which the connecting rods 5 on the second bedplate 3 slide are provided on the front and rear sides of the sliding groove 2. A groove 15 is provided on the top of the second bedplate 3. A support plate 16 is slidably and sealingly connected in the groove 15. Wedge surfaces 17 are provided on the left and right sides of the support plate 16, which facilitates the side wall of the sliding groove 2 to drive the support plate 16 into the groove 15. A plurality of first limiting grooves 18 are spaced apart on the surface of each support plate 16, and limiting strips 19 matching the first limiting grooves 18 are provided on the inner wall of each sliding groove 2.

[0035] A positioning component for adjusting the positions of the support plate 16 and the second bedplate 3 is also provided in the groove 15. The positioning component includes a second threaded rod 20 located on the same straight line as the connecting rod 5. A turning handle 21 is connected to the end of the second threaded rod 20. A threaded hole threadedly connected to the second threaded rod 20 is provided on the front side of the second bedplate 3. Two spaced - apart rotating grooves 22 are provided in the groove 15. Cam 23s are covered on the second threaded rod 20 and are respectively located in the corresponding rotating grooves 22. One end of the cam 23 is located in the rotating groove 22, and the side wall of the cam 23 abuts against the bottom of the support plate 16. A spring 24 is provided on the side of the bottom of the support plate 16 away from the cam 23, and the spring 24 is located in the groove 15.

[0036] On the front and rear side walls of the first bedplate 1 and the second bedplate 3, there are both provided with polygonal second limiting grooves. In this embodiment, the shape of the second limiting groove is a regular hexagon. A limiting ring 25 that matches the shape of the second limiting groove is embedded in the second limiting groove. A guiding rod 26 is fixedly connected to the inner side of the limiting ring 25. A guiding groove 27 that is slidably connected to the guiding rod 26 is provided on the connecting rod 5. The limiting ring 25 is wrapped around the connecting rod 5 and is slidably connected to the connecting rod 5. A tightening nut 28 that abuts against the limiting ring 25 is also threadedly connected to the connecting rod 5. The connecting rod 5 is rotatably connected to the second limiting groove, and a torsion spring is connected between the end of the connecting rod 5 and the second limiting groove.

[0037] The working process of this embodiment:

[0038] During use, when performing an operation on a flat terrain in the wild, by rotating the first threaded rod 7, the rollers 12 can be kept on the same plane. Since the middle roller 12 and the rollers 12 on both sides face different directions, the rollers 12 can be used to prevent the device from moving during the operation. At this time, by adjusting the position of the robotic arm 13, the auxiliary positioning and clamping of different surgical instruments can be realized, which is beneficial to assisting the surgeon to complete the operation when there is a shortage of personnel and is beneficial to improving the practicability of this solution.

[0039] When it is necessary to transfer this device, first rotate the second threaded rod 20 to drive the cam 23 to lower the height of the end of the support plate 16. Then, push the corresponding second bedplate 3 into the chute 2 through the handle 4. At this time, the wedge surface 17 can be used to move the support plate 16 downward. After the second bedplate 3 enters the first bedplate 1, rotate the second threaded rod 20 again to drive the support plate 16 to abut against the top of the chute 2 through the cam 23 and the spring 24. At this time, the first limiting groove 18 is engaged with the limiting strip 19, so that the second bedplate 3 will not shift in position during the movement. By moving the two second bedplates 3 closer to the first bedplate 1, the overall length of the device is effectively reduced, which is beneficial to driving this device to move quickly in the wild by means of the handle 4. At the same time, rotate the first threaded rod 7 in the middle so that the rolling direction of the roller 12 on the first threaded rod 7 is consistent with that of the two rollers 12 on both sides. And before the transfer, by screwing out the tightening nut 28 to separate it from the limiting ring 25, the limiting ring 25 is slid out of the second limiting groove. At this time, the connecting rod 5 can drive the roller 12 to rotate through the sleeve 6 and the first threaded rod 7. Therefore, during the transfer, if encountering a steep slope, obstacle, etc., the roller 12 can smoothly pass through the obstacle by rotating the connecting rod 5, and the balance of the same side of this device can be maintained by using two or three rollers 12 on the same side after crossing the obstacle. At the same time, in order to reduce the labor intensity of personnel during the transfer, the corresponding drive motor 8 can be controlled by a remote control to drive the roller 12 to rotate. The rolling of the roller 12 can improve the transfer efficiency and reduce the pulling force applied to the handle 4 during the transfer.

[0040] When short-distance water transfer is required when encountering a water area, traditional operating beds or surgical equipment need to be transported by drones, helicopters or boats. This process is not easy to control in terms of time, and not all situations can have auxiliary equipment to assist in the transfer. When this device encounters short-distance water transfer, the first threaded rod 7 is used to drive the spiral blades 9 located at both ends to rotate. By turning on the corresponding drive motor 8 through the remote control, the rotation of the spiral blades 9 can be realized, so as to provide power for the movement of this device on the water surface. And the spiral blades 9 with different orientations can provide power for straight movement or left-right rotation, greatly improving the mobility of this solution. And when moving on land, there will be no interference with the fixation of the rollers 12, improving the application range of this solution.

[0041] Embodiment 2

[0042] As Figure 5As shown in the figure, the difference between this embodiment and Embodiment 1 is only that: a vacuumed airbag 29 is fixedly connected to the bottom of the first bedplate 1. A trachea communicating with the airbag 29 penetrates through the first bedplate 1 at one end. The shape of the trachea is in the shape of the letter "L". One end of the trachea penetrates out of the front side wall of the first bedplate 1. A one-way valve is provided in the trachea, and the one-way valve enables air to enter the airbag 29 from the outside but not to flow out. A gas plug 30 is hermetically connected to the end of the trachea.

[0043] The working process of this solution is different from that of Embodiment 1 only in that: when it is necessary to transport other drugs or items through this device in addition to transporting this device, the gas plug 30 can be pulled out. At this time, the negative pressure in the airbag 29 quickly sucks the outside air into the airbag 29. If the air pressure when the airbag 29 expands is insufficient, the airbag 29 can also be inflated through other inflating devices. By means of the airbag 29, the buoyancy of this device is increased, the bearing capacity of this device is improved, and it is beneficial to the smooth transfer of this device through the water area.

[0044] The above are only embodiments of the present invention. Specific structures and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners and the like described in the specification can be used to interpret the content of the claims.
