Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a wearable general surgical instrument. Background Technology

[0002] General surgery is a branch of medicine that focuses on the surgical treatment of multiple organs and systems in the human body. It encompasses a wide range of surgical types, and its treatment methods and techniques are constantly being updated and improved. From the initial simple surgical procedures to today's minimally invasive surgery, robot-assisted surgery, and other high-tech methods, the level of treatment in general surgery has been greatly enhanced.

[0003] In current technologies, surgeons often need to frequently handle surgical instruments during procedures, which increases the complexity and fatigue of the operation. Furthermore, some auxiliary devices are quite heavy, which may interfere with the surgeon's hand dexterity during operation, making certain delicate procedures difficult and reducing surgical efficiency and quality.

[0004] In summary, how to solve the problem that some auxiliary devices in the existing technology are too heavy and may interfere with the doctor's hand dexterity during operation has become an urgent problem to be solved in this field. Therefore, it is necessary to propose a wearable general surgical instrument. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a wearable general surgical instrument. The design of the weight-reducing components makes the entire device lighter, further reducing the burden during wear and thus improving comfort. This allows doctors to focus on the surgery itself, thereby increasing surgical efficiency.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a wearable general surgical instrument, comprising an arc-shaped plate, wherein clamping components for clamping the instrument and rotating components for rotating the arc-shaped plate are respectively provided on both sides of the arc-shaped plate.

[0007] The rotating assembly includes an arc-shaped base plate, a controller, a rack, and a telescopic component for driving the rack. The controller controls the telescopic component to extend and retract, and the telescopic component is fixedly connected to the base plate. The output shaft of the telescopic component is fixedly connected to the rack, which meshes with a gear. The gear is rotatably connected to the base plate. A lever is fixedly connected to the top of the gear, and the lever is fixedly connected to the side of the arc-shaped plate away from the clamping assembly.

[0008] The base plate is equipped with a stabilizing component for stabilizing the movement of the rack and pinion and a weight-reducing component for reducing the weight of the curved plate.

[0009] The technical principles of the above solution are as follows:

[0010] By wearing the curved plate on the surgeon's forearm, the output shaft of the telescopic component is fixedly connected to the rack, which meshes with the gear. Therefore, when the telescopic component moves the rack, the meshing gear rotates. Since a lever is fixedly connected to the top of the gear and to the curved plate, the rotation of the gear drives the lever, which in turn rotates the curved plate. Precise control by the controller allows for adjustment of the curved plate's angle, assisting the surgeon in arm movements. A clamping assembly holds surgical instruments needed during surgery, allowing the surgeon to operate these tools without holding them. Weight-reducing components further reduce the device's weight, increasing flexibility and adaptability.

[0011] The above approach has the following beneficial effects:

[0012] 1. This invention controls the angle of the arc-shaped plate by controlling the movement of the rack and pinion via a telescopic component, which in turn drives the gear and lever to rotate. This mechanical transmission method assists the surgeon in moving their arm, providing additional support and allowing the surgeon to perform the operation with less effort. Furthermore, the weight-reducing components make the entire device lighter, further reducing the burden on the wearer and improving comfort, allowing the surgeon to focus on the operation itself and thus increasing surgical efficiency.

[0013] 2. This invention utilizes a clamping component design to fix or hold various surgical instruments, such as scissors and forceps. This reduces hand tremors for doctors when operating these tools, thereby improving the stability of their hand movements.

[0014] 3. The present invention ensures that the rack remains straight and stable during movement through a stabilizing component, avoiding unnecessary deviation or vibration, and further improving the reliability and accuracy of the device.

[0015] Furthermore, the clamping assembly includes a bracket, symmetrically arranged clamping arms, and an arc-shaped rod. The bracket is ball-jointed to the side of the arc-shaped plate away from the actuating rod. Several hinge rods are symmetrically hinged to the side of the bracket away from the arc-shaped plate, and the ends of the hinge rods away from the bracket are all hinged to the clamping arms. The clamping arms are all hinged to the adjacent arc-shaped rods.

[0016] The bracket is equipped with a drive assembly for driving the lateral movement of the arc-shaped rod.

[0017] Beneficial effects: The arc-shaped rods are moved laterally by the drive assembly. Since the arc-shaped rods are all hinged to the clamping arms, the clamping arms are hinged to the hinge rods, and the hinge rods are hinged to the support, the clamping arms can open and close during the lateral movement of the arc-shaped rods through the hinge action of the hinge rods, thus achieving the clamping action of the clamping arms on the object. The ball joint design of the support allows it to rotate freely, thereby adapting to the operating posture of different surgical instruments.

[0018] Furthermore, the drive assembly includes a lead screw, a nut seat, and a rotating component for rotating the lead screw. The controller is used to control the rotation of the rotating component. The rotating component is fixedly connected to the side of the bracket away from the hinge rod. The output shaft of the rotating component passes through the bracket and is coaxially fixedly connected to the lead screw. The end of the lead screw away from the rotating component is rotatably engaged with the bracket.

[0019] The nut seat is threaded onto the outer wall of the lead screw, and connecting rods are symmetrically fixed to the outer wall of the nut seat; each connecting rod is hinged to the end of the adjacent arc-shaped rod away from the clamping arm.

[0020] The bracket is also equipped with a limiting component to provide a limit for the nut seat.

[0021] Beneficial effects: The rotating component drives the lead screw to rotate. Since the lead screw and the nut seat are threaded together, and the nut seat is symmetrically fixedly connected with connecting rods, all of which are hinged to the arc-shaped rod, the rotation of the lead screw can cause the nut seat to move laterally. The lateral movement of the nut seat then drives the arc-shaped rod to move laterally through the connecting rods.

[0022] Furthermore, the limiting component includes several guide rods, both ends of which are fixedly connected to the bracket; the connecting rod is located in the gap between adjacent guide rods.

[0023] Beneficial effects: The guide rod design ensures that the nut seat remains consistent during lateral movement, reducing the possibility of nut seat deflection and further improving the stability of the device.

[0024] Furthermore, the stabilizing component includes a slider, which is fixedly connected to the bottom of the rack, and the base plate has a groove for the slider to move.

[0025] Beneficial effects: The design of the slider and groove provides a linear movement trajectory for the rack, ensuring that it always moves along a predetermined straight path during motion, effectively reducing lateral displacement.

[0026] Furthermore, the weight reduction component includes a piston rod, a piston cylinder, and a rubber piston. The piston cylinder is fixedly connected to the base plate. One end of the piston rod is fixedly connected to the output shaft of the telescopic component, and the other end of the piston rod is fixedly connected to the rubber piston. The rubber piston slides against the inner wall of the piston cylinder.

[0027] The piston cylinder is connected to an intake pipe and an exhaust pipe on the side away from the telescopic component. The intake pipe is connected to a storage tank for storing light gases. An air bladder is fixedly connected to the arc plate, and the exhaust pipe is connected to the air bladder. One-way valves are connected to the connection points of the intake pipe and the exhaust pipe with the piston cylinder, and the flow direction of the one-way valves is towards the air bladder.

[0028] Beneficial effects: The reciprocating movement of the piston rod, driven by the telescopic component, occurs because the piston rod is fixedly connected to the rubber piston, which slides against the inner wall of the piston cylinder. This reciprocating movement of the piston rod causes the rubber piston to move back and forth within the piston cylinder, creating a negative pressure suction and thrust within the cylinder. Since the piston cylinder is connected to both the storage tank and the air bladder, the negative pressure suction transfers the lightweight gas from the storage tank to the air bladder, reducing the actual weight of the curved plate and thus lessening the burden on the doctor. Furthermore, the doctor's arm rotation during operation causes a momentary increase in lightweight gas, further reducing the device's weight and the effort required to rotate the arm. Continuous arm movement further increases the amount of lightweight gas inside the air bladder, gradually reducing the device's weight; the more operations performed, the lighter it becomes, improving comfort during extended periods of work.

[0029] Furthermore, a first outer shell is fitted onto the outside of the bracket, and a second outer shell is fixedly connected to the base plate.

[0030] Beneficial effects: The design of the first and second outer shells can effectively reduce the entry of external impurities into the moving parts, effectively improve the safety of the device's operation, and thus extend the service life of the device.

[0031] Furthermore, a camera is fixedly connected to the first housing, and a controller is used to receive image information captured by the camera. A display screen for displaying image information is fixedly connected to the top wall of the second housing.

[0032] Beneficial effects: The camera can capture high-definition images of the surgical area and transmit them to a display screen, allowing doctors to view the detailed condition of the surgical site in real time, ensuring more precise operation.

[0033] Furthermore, pressure sensors are symmetrically fixedly connected to the inner wall of the arc-shaped plate; the controller is used to receive the pressure signals detected by the pressure sensors, control the telescopic component to extend and retract based on the pressure signals, and control the extension and retraction length of the telescopic component based on the magnitude of the pressure signals.

[0034] Beneficial effects: By monitoring the doctor's arm movement through pressure sensors, the pressure sensors on both sides of the curved plate receive different pressures when the doctor exerts force, thus determining the doctor's arm exertion state. This allows for the control of the telescopic component to adjust its extension length, thereby regulating the rotational torque of the curved plate and providing assistance to the doctor's arm. This method assists doctors in surgical procedures, and the automated operation mode further improves the comfort of surgical operations.

[0035] Furthermore, a robotic arm is fixedly connected to the second outer shell, and a controller is used to control the operation of the robotic arm.

[0036] Beneficial effects: The robotic arm design enables precise movement of the device in all directions, meeting the different operational needs of various surgeries and thus improving the applicability of the device's movement.

[0037] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0042] The following detailed description illustrates the specific implementation method:

[0043] Example 1:

[0044] As attached Figures 1-3 As shown: A wearable general surgical instrument includes an arc-shaped plate 1, with clamping components for holding the instrument and rotating components for rotating the arc-shaped plate 1 on both sides of the arc-shaped plate 1.

[0045] The rotating assembly includes an arc-shaped base plate 2, a controller, a rack 3, and a telescopic component for driving the rack 3. In this embodiment, the telescopic component is an electric actuator 5. The controller is used to control the extension and retraction of the electric actuator 5. The electric actuator 5 is bolted to the base plate 2. The output shaft of the electric actuator 5 is screwed to the rack 3. The rack 3 is meshed with a gear 4. The gear 4 is rotatably connected to the base plate 2. A lever 6 is fixedly attached to the top of the gear 4. The lever 6 is fixedly bonded to the right side of the arc-shaped plate 1.

[0046] The clamping assembly includes a bracket 7, symmetrically installed clamping arms 8 and arc-shaped rods 9. The bracket 7 is ball-jointed to the left side of the arc-shaped plate 1. Several hinge rods 10 are symmetrically hinged to the left side of the bracket 7, and the other end of each hinge rod 10 is hinged to the clamping arm 8. Each clamping arm 8 is hinged to the adjacent arc-shaped rod 9.

[0047] The bracket 7 is equipped with a drive assembly for driving the lateral movement of the arc-shaped rod 9. The drive assembly includes a lead screw 11, a nut seat 12, and a rotating component for rotating the lead screw 11. In this embodiment, the rotating component is a rotary motor 13, and the controller is used to control the rotary motor 13 to rotate. The rotary motor 13 is bolted to the right side of the bracket 7, and the output shaft of the rotary motor 13 passes through the bracket 7 and is coaxially fixedly engaged with the lead screw 11. The left end of the lead screw 11 is rotatably engaged with the bracket 7.

[0048] The nut seat 12 is threaded onto the outer wall of the lead screw 11. The outer wall of the nut seat 12 is integrally formed with connecting rods 14 symmetrically. Each connecting rod 14 is hinged to the right end of the adjacent arc-shaped rod 9.

[0049] The bracket 7 is also equipped with a limiting assembly for limiting the nut seat 12. The limiting assembly includes several guide rods 15, both ends of which are fixedly connected to the bracket 7 with screws; the connecting rod 14 is located in the gap between adjacent guide rods 15. The design of the guide rods 15 ensures that the nut seat 12 remains consistent during lateral movement, reduces the possibility of the nut seat 12 deflecting, and further improves the stability of the device.

[0050] The base plate 2 is provided with a stabilizing component for stabilizing the movement of the rack 3 and a weight-reducing component for reducing the weight of the arc plate 1.

[0051] The stabilizing component includes a slider, which is fixedly connected to the bottom of the rack 3 with screws. The base plate 2 has a groove for the slider to move. Through the design of the slider and the groove, a linear movement trajectory can be provided for the rack 3, so that it always moves along a predetermined straight path during the movement, effectively reducing lateral displacement.

[0052] Combination Figure 3 As shown, the weight reduction assembly includes a piston rod 16, a piston cylinder 17, and a rubber piston. The piston cylinder 17 is screwed and fixedly connected to the base plate 2. One end of the piston rod 16 is screwed and fixedly connected to the output shaft of the electric actuator 5, and the other end of the piston rod 16 is fixedly bonded to the rubber piston. The rubber piston slides against the inner wall of the piston cylinder 17.

[0053] The piston cylinder 17 has an intake pipe and an exhaust pipe connected to its right side. The intake pipe is connected to a storage tank for storing light gas. In this embodiment, helium can be used as the light gas. An air bladder is fixedly attached to the arc plate 1, and the exhaust pipe is connected to the air bladder. One-way valves are connected to the connection points of the intake pipe and the exhaust pipe with the piston cylinder 17. The flow direction of the one-way valves is towards the air bladder.

[0054] The specific implementation process is as follows:

[0055] Before surgery, the arc-shaped plate 1 is worn on the doctor's forearm. In this embodiment, Velcro or similar fasteners can be used to attach the arc-shaped plate 1 to the doctor's forearm. Since the output shaft of the electric actuator 5 is fixedly connected to the rack 3 with screws, and the rack 3 meshes with the gear 4, the electric actuator 5 moves the rack 3, causing the meshing gear 4 to rotate. Since a lever 6 is fixedly attached to the top of the gear 4, and the lever 6 is fixedly bonded to the arc-shaped plate 1, the rotation of the gear 4 drives the lever 6 to rotate, thereby causing the arc-shaped plate 1 to rotate.

[0056] by Figure 3 For example, when the electric actuator 5 moves the rack 3 to the right, the gear 4 rotates counterclockwise, which in turn drives the lever 6 to rotate to the left. Conversely, when the electric actuator 5 moves the rack 3 to the left, the gear 4 rotates clockwise, which in turn drives the lever 6 to rotate to the right. The lever 6 then drives the arc plate 1 to rotate synchronously. Through precise control of the controller, the angle of the arc plate 1 can be adjusted to assist the doctor in arm movements.

[0057] The screw 11 is rotated by rotating the motor 13. Since the screw 11 is threadedly engaged with the nut seat 12, and the outer wall of the nut seat 12 is integrally formed with symmetrical connecting rods 14, all of which are hinged to the arc rod 9, the screw 11 can rotate laterally, and the lateral movement of the nut seat 12 is driven by the connecting rods 14 to move the arc rod 9 laterally.

[0058] Since the arc-shaped rods 9 are all hinged to the clamping arms 8, the clamping arms 8 are hinged to the hinge rods 10, and the hinge rods 10 are hinged to the support 7, during the lateral movement of the arc-shaped rods 9, the clamping arms 8 can open and close through the hinge action of the hinge rods 10, thereby achieving the clamping function of the clamping arms 8 on the surgical instruments, allowing the doctor to operate these instruments without holding them by hand. Figure 2 For example, when the lead screw 11 drives the nut seat 12 to move to the left, it drives the arc-shaped rod 9 to press and push the adjacent clamping arms 8 together, thus clamping the clamping arms 8; conversely, when the lead screw 11 drives the nut seat 12 to move to the right, it drives the arc-shaped rod 9 to stretch to the right, thus unfolding the clamping arms 8. The ball joint design of the bracket 7 allows it to rotate freely, adapting to the operating postures of different surgical instruments.

[0059] The electric actuator 5 drives the piston rod 16 to reciprocate. Since the piston rod 16 is fixedly bonded to the rubber piston, and the rubber piston slides against the inner wall of the piston cylinder 17, the reciprocating motion of the piston rod 16, driven by the electric actuator 5, causes the rubber piston to reciprocate within the piston cylinder 17, creating a negative pressure suction and thrust within the piston cylinder 17. Because the piston cylinder 17 is connected to both the storage tank and the air bladder, the negative pressure suction transfers helium from the storage tank to the air bladder. Since helium is less dense than air, and the air bladder is fixedly bonded to the arc-shaped plate 1, the air bladder tends to move the arc-shaped plate 1 upwards, reducing its actual weight and thus the burden on the doctor. Furthermore, during the doctor's operation, arm movement causes the piston rod 16 to move the rubber piston once, achieving one gas transfer. This movement is synchronized with arm movement, allowing helium to be instantly filled into the air bladder, achieving an instantaneous weight reduction effect on the device, thus reducing the effort required for the doctor's arm movements and making arm movements easier. Furthermore, by continuously rotating its arm, the electric actuator 5 will continuously drive the piston rod 16 to reciprocate, thereby continuously increasing the helium inside the airbag. The increase in helium will gradually reduce the weight of the device, making the device lighter the more it is operated, improving the comfort of long-term work, and thus increasing flexibility and adaptability.

[0060] In existing technologies, some auxiliary devices are quite heavy, which may interfere with the surgeon's hand dexterity during operation. This embodiment addresses this by controlling the electric actuator 5 to move the rack 3, which in turn drives the gear 4 and the actuating lever 6 to rotate, thus controlling the angle of the arc-shaped plate 1. This mechanical transmission method assists the surgeon's arm movement, providing additional support and allowing the surgeon to perform the surgery with less effort. Furthermore, the gradual helium infusion design makes the entire device lighter, further reducing the burden of wearing it and improving comfort. This allows the surgeon to focus on the surgery itself, thereby increasing surgical efficiency.

[0061] The clamping arm 8 is designed to fix or hold various surgical instruments, such as scissors and forceps. This reduces hand tremors when the surgeon operates these tools, thereby improving the stability of the surgeon's hand movements. The slider and groove ensure that the rack 3 remains straight and smooth during movement, avoiding unnecessary deviations or vibrations, further improving the reliability and accuracy of the device.

[0062] Example 2:

[0063] As attached Figure 1 As shown, the difference from the above embodiment is that the first outer shell 18 is screwed onto the outside of the bracket 7, and the second outer shell 19 is fixedly connected to the base plate 2 by screws.

[0064] The specific implementation process is as follows: Through the design of the first outer shell 18 and the second outer shell 19, the entry of external impurities into the moving parts can be effectively reduced, the safety of the device movement can be effectively improved, and the service life of the device can be extended.

[0065] Example 3:

[0066] As attached Figure 1 As shown, the difference from the above embodiment is that a camera is fixedly connected to the first housing 18 with screws, and the controller is used to receive image information captured by the camera. A display screen for displaying image information is fixedly connected to the top wall of the second housing 19 with screws.

[0067] The specific implementation process is as follows: The camera can capture high-definition images of the surgical area and transmit them to the display screen, allowing doctors to view the detailed condition of the surgical site in real time, ensuring that doctors can operate more accurately.

[0068] Example 4:

[0069] The difference from the above embodiments is that pressure sensors are symmetrically fixedly bonded to the inner wall of the arc plate 1; the controller is used to receive the pressure signal detected by the pressure sensor, control the extension and retraction of the electric push rod 5 based on the pressure signal, and control the extension and retraction length of the electric push rod 5 based on the magnitude of the pressure signal.

[0070] The specific implementation process is as follows: Pressure sensors monitor the movement of the surgeon's arm. When the surgeon exerts force, the pressure sensors on both sides of the arc-shaped plate 1 receive different pressures, thus determining the surgeon's arm's exertion state. This, in turn, controls the electric actuator 5 to adjust its extension and retraction length, thereby adjusting the rotational torque of the arc-shaped plate 1 and providing assistance to the surgeon's arm. This method assists the surgeon in performing surgical procedures, and the automated operation mode further improves the surgeon's comfort during surgery.

[0071] Example 5:

[0072] The difference from the above embodiments is that a robotic arm is also bolted to the second housing 19, and the controller is used to control the operation of the robotic arm.

[0073] The specific implementation process is as follows: Through the design of the robotic arm, the device can be precisely moved in all directions to meet the different operational needs of different surgeries, thereby improving the applicability of the device's movement.

[0074] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
