Abstract
Description
Technical Field
[0001] This invention relates to the field of orthopedic nursing technology, and more particularly to an orthopedic nursing drilling device. Background Technology
[0002] In orthopedic nursing clinical work, drilling equipment is an indispensable core tool, widely used in fracture reduction and fixation, bone tissue biopsy, joint replacement, osteomyelitis debridement, and other nursing and adjuvant treatment scenarios. The drilling accuracy and operational safety directly affect the patient's treatment outcome and postoperative rehabilitation, and even influence limb function recovery. During orthopedic drilling, the affected area is prone to displacement due to pain, muscle spasms, or involuntary movements. Drilling operations require extremely high stability and depth control. However, existing orthopedic drilling equipment lacks precise displacement monitoring and emergency protection structures. When the affected area experiences slight displacement, drilling cannot be automatically stopped in time, easily leading to drill bit damage to surrounding blood vessels, nerves, and normal bone tissue, causing medical risks. Furthermore, the lack of reliable support guidance and depth limiting structures makes the equipment prone to shaking during drilling, causing drill deviation, and making it difficult to accurately control the drilling depth. Excessive drilling depth can damage internal bone structures, failing to meet the core requirements of "precision, safety, and stability" in orthopedic nursing, thus restricting the safety and standardization of orthopedic drilling operations.
[0003] To address the above problems, this invention proposes an orthopedic nursing drilling device. Summary of the Invention

A longitudinal self-locking telescopic rod is fixedly connected to the top of the clamp, and a transverse self-locking telescopic rod is fixedly connected to the top of the longitudinal self-locking telescopic rod. A fixing member is fixedly connected to one end of the transverse self-locking telescopic rod.
[0010] Preferably, the guide assembly includes a mounting plate, with two guide rods, two first springs and two telescopic cloth covers fixedly connected above the mounting plate, and a mounting plate fixedly connected to the top of the guide rods, the mounting plate being fixed to the fixing member by bolts.
[0011] Preferably, a guide sleeve is fitted on the guide rod, the guide sleeve is fixedly connected to the mounting cylinder, and the lower part of the guide sleeve is fixedly connected to the telescopic cloth cover and the top end of the first spring.
[0012] Preferably, the adjustable alarm assembly includes a slide rod that extends upward through the mounting cylinder and is fixed to the alarm. A third spring is fixedly connected to the bottom of the slide rod and is fixedly connected to the top wall of the mounting cylinder.
[0013] Preferably, the mounting cylinder has two sliding grooves, and a top rod is fixedly connected to the top wall of the mounting cylinder.
[0014] Preferably, the drilling assembly includes a connector, in which a drill bit is disposed, and the connector is rotatably mounted on a guide bar via a bearing, wherein the two ends of the guide bar are slidably connected in two grooves respectively.
[0015] Preferably, a bevel gear shaft is fixedly connected to the top of the connector, the bevel gear shaft is rotatably mounted on the fixed plate through a bearing, the fixed plate is fixedly connected to the bottom end of the slide rod, the fixed plate is fixedly connected to two limiting blocks, and sliders are fixedly connected to both sides of the fixed plate, the sliders are slidably connected in the slide groove.
[0016] Preferably, the drive assembly includes a handle, which is fixedly mounted on the mounting cylinder, and a motor is installed in the handle. The output shaft of the motor is fixedly connected to a first bevel gear.
[0017] Preferably, the pneumatic limiting assembly includes two side cavities, which are respectively fixedly connected to both sides of the fixed cylinder. A piston locking rod is provided in each side cavity, and one end of the piston locking rod and the limiting block are set as an inclined surface.
[0018] A second spring is fixedly connected between the piston locking rod and the side wall of the side cavity. The two side cavities are connected to both ends of the hose. The hose is connected to the airbag ring. The airbag ring is located between the positioning ring and the mounting plate. Multiple elastic bands are fixedly connected to the outer periphery of the mounting plate. The multiple elastic bands are fixedly connected to the positioning ring.
[0019] Compared with the prior art, the present invention provides an orthopedic nursing drilling device, which has the following beneficial effects:
[0020] 1. This orthopedic nursing drilling device uses a pneumatic limiting component to contact the patient's affected area. When the patient's muscles spasm or move unconsciously, the pneumatic limiting component shifts and the drilling component is released from its locked state using pneumatic control. At this time, the adjustable alarm component drives the drilling component to retract the drill bit and emits an audible and visual alarm signal to remind medical staff to deal with the situation in time. This prevents the drill bit from continuing to drill due to displacement of the affected area, which could damage surrounding normal bone tissue, blood vessels, and nerves. It effectively solves the problems of secondary injury caused by displacement of the affected area and the lack of safety warnings, thereby significantly improving the safety of orthopedic nursing drilling operations.
[0021] 2. This orthopedic nursing drilling device allows for the selection of a suitable fixed position through the adjustment of the horizontal and vertical components, ensuring stable support for the device. Simultaneously, the guide component provides precise movement guidance for the drilling component, limiting its swaying or deviation and ensuring the drill bit always drills in the preset direction. Furthermore, the mounting cylinder is equipped with an adjustable baffle, allowing medical staff to precisely set the drilling depth in advance according to nursing and treatment needs. During drilling, when the drill bit reaches the preset depth, the baffle automatically limits its movement, preventing further drilling and completely avoiding the problems of drilling too deep and damaging the internal bone structure or drilling too shallow and failing to meet treatment needs. This reduces the professional difficulty and, at the same time, employs auxiliary methods to improve drilling accuracy.
[0022] 3. This orthopedic nursing drilling equipment ensures the stability of the drilling components through an adjustable component. Combined with a guide component, it effectively reduces the disturbance to the affected area caused by equipment shaking during drilling, lowering the probability of patient discomfort and subsequent displacement of the affected area due to equipment shaking. This provides a stable foundation for the precise operation of the pneumatic limiting component, preventing misjudgments and accidental triggering of emergency mechanisms due to equipment shaking. The pneumatic limiting component, in conjunction with the adjustable alarm component, can promptly terminate drilling operations in case of unexpected displacement of the affected area, preventing secondary injuries caused by the guide component's inability to completely limit displacement. The two components work together to achieve an integrated effect of stable support, precise guidance, controllable depth, and displacement protection, ensuring drilling accuracy and operational safety while improving the efficiency and standardization of nursing operations, making it suitable for various orthopedic nursing drilling scenarios.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0035] Example 1: Refer to Figures 1-2 and Figures 4-9 An orthopedic nursing drilling device includes a drilling support mechanism 100, on which a drilling mechanism 200 is provided;
[0036] The drilling support mechanism 100 includes two adjusting components 101. A guide component 102 is provided at one end of each adjusting component 101. A mounting cylinder 104 is provided on the guide component 102. An adjustable alarm component 105 passes through the mounting cylinder 104. The adjustable alarm component 105 includes a slide rod 1051, which extends upward through the mounting cylinder 104 and is fixed to an alarm 1053. A third spring 1052 is fixedly connected to the bottom of the slide rod 1051. The third spring 1052 drives the drilling component 202 upward to quickly withdraw from the patient's affected area, reducing patient injury. Simultaneously, it drives the slide rod 1051 to lift the alarm 1053. This can effectively serve as an early warning system. The third spring 1052 is fixedly connected to the top wall of the mounting cylinder 104. Two sliding grooves 108 are provided on the mounting cylinder 104. A top rod 107 is fixedly connected to the top wall of the mounting cylinder 104. A pneumatic limiting assembly 103 is provided on the mounting cylinder 104. The pneumatic limiting assembly 103 includes two side cavities 1035, which are respectively fixedly connected to the two sides of the fixed cylinder. A piston locking rod 1037 is provided in the side cavity 1035. One end of the piston locking rod 1037 and the limiting block 204 are set as an inclined surface. Through the inclined surface design of the piston locking rod 1037 and the limiting block 204, the inclined surface can be used to lock the piston locking rod 1037. The compression motion causes the piston locking rod 1037 to move away from the limiting block 204, allowing the drill bit 2021 assembly to smoothly complete its downward reset, facilitating subsequent drilling operations. Simultaneously, after the second spring 1036 drives the piston locking rod 1037 to reset, it allows the piston locking rod 1037 to smoothly lock with the limiting block 204, preparing for subsequent warning operations. A second spring 1036 is fixedly connected between the piston locking rod 1037 and the side wall of the side cavity 1035. The two side cavities 1035 are connected to both ends of the hose 1034. The hose 1034 connects the side cavities 1035 and the airbag ring 1033, ensuring normal air supply operations. Meanwhile, the hose 1034... 34. The retractable movement allows drilling operations to proceed smoothly. The hose 1034 is connected to the airbag ring 1033. The airbag ring 1033 is located between the positioning ring 1031 and the mounting plate 1021. Multiple elastic bands 1032 are fixedly connected to the outer periphery of the mounting plate 1021. The elastic bands 1032 can support the positioning ring 1031, ensuring the stability of the positioning ring 1031. The elastic bands 1032 can move under force, ensuring that the airbag ring 1033 can smoothly compress the mounting plate and the positioning ring 1031. The multiple elastic bands 1032 of the airbag are fixedly connected to the positioning ring 1031. The pneumatic limiting component 103 extends downward to the bottom of the guide component 102.
[0037] The drilling mechanism 200 includes a drive assembly 201, which includes a handle 2011. The handle 2011 is fixedly mounted on the mounting cylinder 104. The drilling assembly 202 can be easily controlled to perform drilling operations via the handle 2011. A motor 2012 is installed in the handle 2011. The output shaft of the motor 2012 is fixedly connected to a first bevel gear 2013. The first bevel gear 2013 of the drive assembly 201 meshes with the bevel gear shaft 2024 of the drilling assembly 202. The drilling assembly 202 includes a connector 2022, in which a drill bit 2021 is disposed. The connector 2022 is rotatably mounted on a guide bar 2023 via a bearing. The connector 2022 can be kept stable by the bearing, thereby enabling the drill bit 2021 to perform drilling operations stably. The two ends of the guide bar 2023 are slidably connected in two grooves 108, respectively. The guide bar 2023 can slide smoothly in the slide groove 108, allowing the drill bit 2021 assembly to move smoothly up and down. A bevel gear shaft 2024 is fixedly connected above the connector 2022. The bevel gear shaft 2024 is rotatably mounted on the fixed plate 2025 through bearings. The fixed plate 2025 is fixedly connected to the bottom end of the slide rod 1051. The fixed plate 2025 is fixedly connected to two limit blocks 204. Slider blocks 2026 are fixedly connected to both sides of the fixed plate 2025. The sliders 2026 are slidably connected in the slide groove 108. The sliding cooperation between the sliders 2026 and the slide groove 108 ensures the stable sliding of the drill bit 2021 assembly. The upper part of the drilling assembly 202 is connected to the adjustable alarm assembly 105 and the switch 203. The two piston locking rods 1037 of the pneumatic limit assembly 103 are locked with the two limit blocks 204 to limit the drilling assembly 202.
[0038] In this embodiment: the pneumatic limiting component 103 contacts the patient's affected area. When the patient's affected area experiences muscle spasm or unconscious movement, the positioning ring 1031 causes the airbag ring 1033 to shift, creating pressure between the airbag ring 1033 and the mounting plate 1021. This allows gas to enter the side cavity 1035 and controls the piston locking rod 1037 to retract and disengage from the limiting block 204, releasing the locking state of the drilling component 202. At this time, the third spring 1052 drives the drilling component 202 to retract the drill bit 2021 and causes the switch 203 to contact the top rod 107, triggering the alarm 1053 to emit an audible and visual alarm signal. This alerts medical staff to handle the situation promptly, preventing the drill bit 2021 from continuing to drill due to displacement of the affected area, which could damage surrounding normal bone tissue, blood vessels, and nerves. This effectively solves the problems of secondary injury caused by displacement of the affected area and the lack of safety warnings, thereby significantly improving the safety of drilling operations in orthopedic nursing.
[0039] Example 2: Refer to Figures 3-4An orthopedic nursing drilling device includes an adjusting assembly 101. The adjusting assembly 101 includes a clamp 1013, on which a fixing structure 1014 is provided. The fixing structure 1014 can be a bolt, a clip, or other fixing structure 1014, thereby ensuring the stability of the adjusting assembly 101. A longitudinal self-locking telescopic rod 1011 is fixedly connected to the upper part of the clamp 1013, and a transverse self-locking telescopic rod 1012 is fixedly connected to the top of the longitudinal self-locking telescopic rod 1011. The longitudinal self-locking telescopic rod 1011 and the transverse self-locking telescopic rod 1012 are connected to each other. The longitudinal and lateral adjustments of the self-locking telescopic rod 1012 can meet the fixing requirements and ensure that the drill bit 2021 corresponds to the affected area for easy drilling. One end of the lateral self-locking telescopic rod 1012 is fixedly connected to a fixing member 1015. A baffle 106 is fixed to the mounting cylinder 104 by bolts. The position of the baffle 106 on the mounting cylinder 104 can be adjusted to facilitate the adjustment of the drilling depth. The bolts can fix the position of the baffle 106 so that the baffle 106 contacts the mounting plate 1026 to limit the position of the drill bit 2021 and improve the drilling accuracy.
[0040] The guide assembly 102 includes a mounting plate 1021. Two guide rods 1023, two first springs 1022, and two telescopic covers 1024 are fixedly connected to the upper part of the mounting plate 1021. A mounting plate 1026 is fixedly connected to the top of the guide rods 1023. The mounting plate 1026 is fixed to the fixing member 1015 by bolts. A guide sleeve 1025 is sleeved on the guide rods 1023. The guide sleeve 1025 is fixedly connected to the mounting cylinder 104. By sliding the guide sleeve 1025 on the guide rods 1023, the drill bit 2021 assembly can be accurately guided. The lower part of the guide sleeve 1025 is fixedly connected to the top of the telescopic covers 1024 and the first springs 1022. The first springs 1022 can drive the mounting cylinder 104 to smoothly return to its original position, which is convenient for removing the drill bit 2021. In addition, the telescopic covers 1024 can protect the first springs 1022 and improve operational safety.
[0041] In this embodiment: by adjusting the lateral and longitudinal directions of component 101, a suitable fixed position can be selected to ensure stable support for the device. At the same time, guide component 102 can provide precise movement guidance for drilling component 202, limiting the shaking or deviation of drilling component 202 and ensuring that drill bit 2021 always drills in the preset direction. Secondly, the mounting cylinder 104 is equipped with an adjustable baffle 106. Medical staff can accurately set the drilling depth in advance according to nursing and treatment needs. During the drilling process, when drill bit 2021 reaches the preset depth, baffle 106 automatically limits the drilling and prevents drill bit 2021 from continuing to drill, completely avoiding the problem of drilling too deep and damaging the internal bone structure or drilling too shallow and failing to meet treatment needs, reducing professional difficulty. At the same time, auxiliary methods are used to improve drilling accuracy.
[0042] Example 3: Reference Figures 1-2 andFigures 4-5 An orthopedic nursing drilling device includes a drilling support mechanism 100. The drilling support mechanism 100 includes two adjusting components 101. A guide component 102 is provided at one end of the two adjusting components 101 opposite to each other. An installation cylinder 104 is provided on the guide component 102. A baffle 106 is fixed on the installation cylinder 104 by bolts. An adjustable alarm component 105 is provided through the installation cylinder 104. A pneumatic limit component 103 is provided on the installation cylinder 104 and extends downward to below the guide component 102.
[0043] The drilling mechanism 200 includes a drive assembly 201. The first bevel tooth 2013 of the drive assembly 201 meshes with the bevel tooth shaft 2024 of the drilling assembly 202. The upper part of the drilling assembly 202 is connected to the adjustable alarm assembly 105 and the switch 203. The two piston locking rods 1037 of the pneumatic limit assembly 103 are locked with the two limit blocks 204 to limit the drilling assembly 202.
[0044] In this embodiment: the stability of the drilling assembly 202 is ensured by adjusting the component 101, and the guide component 102 can effectively reduce the disturbance of the affected area caused by the shaking of the equipment during drilling, reducing the probability of discomfort caused by the shaking of the equipment and resulting in displacement of the affected area. This provides a stable foundation for the precise operation of the pneumatic limiting component 103, avoiding misjudgment and false triggering of the emergency mechanism due to equipment shaking. The pneumatic limiting component 103 can, in conjunction with the adjustable alarm component 105, terminate the drilling operation of the drilling assembly 202 in time when the affected area is unexpectedly displaced, avoiding secondary damage caused by the guide component 102's inability to completely limit the displacement. The two work together to achieve an integrated effect of stable support, precise guidance, controllable depth and displacement protection, which not only ensures drilling accuracy and operational safety, but also improves the efficiency and standardization of nursing operations, and is suitable for various orthopedic nursing drilling scenarios.
[0045] Working principle: During drilling, the position of the drilling assembly 202 is adjusted by the longitudinal self-locking telescopic rod 1011 and the transverse self-locking telescopic rod 1012. At the same time, the locking device of the fixed structure 1014 keeps it stable. Then, by pressing down the handle 2011, the drilling assembly 202 and the pneumatic limiting assembly 103 are moved. The mounting cylinder 104 slides smoothly downward through the guide sleeve 1025, while the positioning ring 1031 is pre-pressed around the skin of the patient's affected area, so that the drill bit 2021 contacts the affected area downward. The motor 2012 controls the transmission between the first bevel tooth 2013 and the bevel tooth shaft 2024, so that the connector 2022 drives the drill bit 2021 to rotate downward for drilling. When the baffle 106 contacts the mounting plate 1026, the drilling operation is completed.
[0046] When the patient experiences involuntary muscle activity at the affected area, the skin and muscles move the positioning ring 1031. The positioning ring 1031 causes the airbag ring 1033 to be squeezed against the mounting plate 1021, allowing gas to enter the side cavity 1035 through the hose 1034. The air pressure controls the piston locking rod 1037 to disengage from the limit block 204. At this time, the third spring 1052 drives the fixing plate 2025 to return to its original position. The slide rod 1051 lifts the alarm 1053. Simultaneously, the drilling assembly 202 quickly disengages from the patient's affected area, and the water switch 203 contacts the top rod 107. At this time, the alarm 1053 activates an audible and visual alarm.
[0047] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
