Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a bone needle auxiliary puncture device. Background Art

[0002] Bone puncture is a common clinical procedure, widely used in the diagnosis and treatment of bone-related diseases. The main uses of bone puncture include sampling and testing, drug delivery, bone marrow transplantation, and therapeutic decompression. The implementation of bone puncture technology relies on doctors or clinical medical staff to penetrate the patient's bone tissue through a puncture needle and enter the bone marrow cavity or related treatment area to achieve clinical diagnosis or treatment purposes. However, bone puncture surgery has high technical requirements and there are many challenges in the clinical operation process.

[0003] First of all, the accuracy of the bone puncture process is crucial. Due to differences in patients' physical conditions, the complexity of their anatomical structures, and the small puncture area, deviations in the puncture path or puncture failure may lead to complications such as tissue damage, bone puncture failure, bleeding, and infection. Therefore, how to stabilize the puncture path through mechanical means and reduce the difficulty of surgical operations has become an important direction for clinical technology research.

[0004] Secondly, during the current bone puncture operation, factors such as hand shaking and hand-eye coordination also directly affect the stability and accuracy of the puncture path. Especially in the puncture positioning link, if the puncture path cannot be effectively controlled, it may cause the puncture needle to fail to be correctly positioned or the path to deviate. In this case, doctors or medical staff rely on hand strength to perform the puncture operation, which is prone to operational errors and thus affects the surgical effect.

[0005] At present, the technical equipment used in clinical bone puncture assistance mainly relies on electronic sensors, computer guidance or other high-tech equipment, but such equipment is usually complex, expensive, and depends on the technical proficiency of the operator. In addition, these electronic technical equipment may not be suitable for all patients, especially in some areas with limited medical resources, where equipment costs and technical maintenance will become a significant obstacle.

[0006] Therefore, how to design a simple, reliable and mechanized bone puncture assisting device has become an important demand for the current development of clinical technology. This device should have the following features: stable positioning, mechanized operation, avoid over-reliance on electronic equipment, and minimize the patient's discomfort to make the puncture process safer and more efficient. In the development of related technologies, it is necessary to provide a bone puncture assisting tool that is highly practical, low-cost and easy to operate through mechanical structure innovation, path control means optimization, and clamping and positioning function enhancement.

[0007] The existing bone puncture assisting technologies mainly rely on mechanical clamps and electric devices, but these technologies still have problems such as high difficulty in operation, limited scope of application, and technical risks of relying on power supply or electronic control. Therefore, it is an important direction for the current technological development to develop a puncture assisting device based on pure mechanical design to meet the functional requirements of stable clamping, precise path positioning, and reduced jitter effects, while simplifying the use process.

[0056] The present invention will be further described below in conjunction with the accompanying drawings.

[0057] like Figures 1 to 19 As shown, a bone needle auxiliary puncture device comprises:

[0058] The bracket 1 is provided with a guide groove 14 in the middle and slots 15 symmetrically provided at both ends; the bracket 1 is placed on the patient's body, and the guide groove 14 is placed above the position to be punctured; the bracket 1 is made of high-strength alloy material as a whole, and has good corrosion resistance and tensile strength, which can ensure that the device maintains stability and does not deform during the puncture process.

[0060] The directional unit 2 includes a slider 23, a damping rod 21 and a directional sleeve 22; the slider 23 is slidably installed in the guide groove 14; a puncture hole 231 is provided in the middle of the slider 23, and a first positioning bolt 24 matching with the bracket 1 is provided on one side; the first positioning bolt 24 is loosened so that the slider 23 can slide in the guide groove 14 to adjust the position of the slider 23 so that the puncture hole 231 is aligned with the area to be punctured, and the first positioning bolt 24 is tightened to fix the slider 23; the top of the damping rod 21 is fixedly connected to the directional sleeve 22, and the bottom is hingedly installed on the slider 23, and a second positioning bolt 27 matching with the slider 23 is provided on one side; the second positioning bolt 27 is loosened so that the damping rod 21 can rotate at its hinge point with the slider 23 to adjust the inclination angle of the directional sleeve 22; the directional sleeve 22 can be adjusted in angle according to the puncture needs to make the puncture path more accurate and meet the body characteristics of different patients.

[0061] The locking unit 3 includes a holder 31 and a locker; the locker is installed in the directional sleeve 22 and fixed by screws, and can be removed from the directional sleeve 22; the holder 31 is fixedly installed on the upper part of the locker, and a slot adapted to the bone puncture needle is provided in the holder 31; the bone puncture needle is installed in the slot of the holder 31, and the holder 31 is rotated to drive the locker to tighten and fix the bone puncture needle in the locker. The locking unit 3 is designed to be a quickly disassembled structure, which is convenient for cleaning and disinfection after use, and provides a precise positioning function.

[0062] The bracket 1 is placed on the patient's body and fixed by the clamping unit 4. The slider 23 is adjusted to the top of the area to be punctured and the slider 23 is fixed. The angle of the directional sleeve 22 is adjusted so that the extension line of the axis of the directional sleeve 22 passes through the point to be punctured. The lower end of the damping rod 21 is fixed, and the puncture needle is installed in the holder 31. The needle of the bone puncture needle passes through the puncture hole 231 toward the area to be punctured on the patient's body. The puncture needle is rotated to drive the holder 31 to rotate so that the locker clamps the puncture needle. Continuing to rotate the puncture needle will cause the locker to rotate around the axis of the directional sleeve 22 to facilitate puncture. The damping rod 21 can slow down the shaking of the hand during puncture, making the puncture smoother.

[0063] In this embodiment, two damping rods 21 are configured; the two damping rods 21 are symmetrically arranged on both sides of the puncture hole 231 to prevent the directional sleeve 22 from rotating around the axis of the damping rod 21, while providing better stability and accuracy.

[0064] In this embodiment, a support plate 25 is fixedly provided on the side of the slider 23; a screw hole matching the first positioning bolt 24 is provided on the support plate 25, and the first positioning bolt 24 is installed on the screw hole on the support plate 25; a first positioning bar 16 matching the first positioning bolt 24 is fixedly provided on the bracket 1, and a plurality of first positioning grooves are provided on the first positioning bar 16, and the first positioning grooves are distributed at equal intervals along the length direction of the first positioning bar 16. The first positioning bolt 24 is screwed down, so that the lower end of the first positioning bolt 24 is squeezed into the first positioning groove, and the slider 23 is fixed on the bracket 1. This design makes the positioning more accurate and enhances the anti-interference performance of the device during use.

[0065] In this embodiment, the locker includes an outer ring 35, a middle ring 36, an inner ring 34 and a locking plate 33; the middle ring 36 is rotatably mounted on the outside of the inner ring 34; the outer ring 35 is rotatably mounted on the outside of the middle ring 36; the holder 31 is fixed to the top of the inner ring 34; the friction between the middle ring 36 and the outer ring 35 is greater than the friction between the inner ring 34 and the middle ring 36; the outer side surface of the outer ring 35 is fixedly arranged with the inner side surface of the directional sleeve 22; the inner ring 34 is provided with a first through hole 341, and the middle ring 36 is provided with a second through hole 361; one end of the locking plate 33 is placed in the second through hole 361, and the other end passes through the first through hole 341 and extends to the interior of the inner ring 34; the locking plate 33 is provided with a first mounting hole 331 and an elliptical hole 332, and a first shaft rod is fixedly arranged in the first through hole 341, and the first shaft rod passes through the first mounting hole 331, and the diameter of the first shaft rod is smaller than the diameter of the first mounting hole 331; a second shaft rod is fixedly arranged in the second through hole 361, and the second shaft rod passes through the elliptical hole 332, and the diameter of the second shaft rod is smaller than the diameter of the elliptical hole 332; the locking plates 33 are configured with at least two, which are distributed in a circular array with the axis of the inner ring 34 as the center. The friction between the inner ring 34 and the middle ring 36 is small, and the rotating holder 31 drives the inner ring 34 to rotate. At this time, the middle ring 36 remains stationary, and the inner ring 34 pulls the locking plate 33 to move, so that the end of the locking plate 33 is squeezed on the upper part of the needle head of the bone needle. The bone needle is clamped by multiple locking plates 33, so that the bone needle will not shake in the axial direction of the inner ring 34. At the same time, the holder 31 clamps the handle of the bone needle to fix it, and the holder 31 continues to be rotated. The torsional force is greater than the friction between the middle ring 36 and the outer ring 35, and the middle ring 36 rotates, so that the bone needle can be rotated for puncture, and the holder 31 is rotated in the opposite direction to make the locking plate 33 break away from the contact with the bone needle, which is convenient for removing the bone needle.

[0066] In this embodiment, a silicone bushing 32 is fixedly provided inside the inner ring 34, and the axis of the silicone bushing 32 coincides with the axis of the inner ring 34, thereby ensuring the cleanliness of the bone puncture needle and preventing the bone puncture needle from being squeezed and deformed, thereby improving the safety of use.

The bracket 1 is integrally provided with a second positioning strip adapted to the paddle 43, and the second positioning strip is provided with a plurality of second positioning grooves 11, which are evenly spaced along the length direction of the second positioning strip, so that the paddle 43 can be fixed at multiple positions as needed. The end of the paddle 43 away from the slider 23 is pressed and contacted with the second positioning strip; the arc rod 41 is fixed to the lower end of the adjustment block 42, which can provide additional clamping force during adjustment to enhance the stability of the device. When the adjusting block 42 is pushed toward the depth of the slot 15, the torsion spring makes one end of the paddle 43 always stuck in the second positioning groove 11, fixing the position of the adjusting block 42 on the bracket 1 and maintaining the clamping effect of the arc rod 41; when removing the bracket 1, press the other end of the paddle 43 to make the paddle 43 disengage from the second positioning groove 11, and under the action of the reset spring 46, the adjusting block 42 returns to its original position, which is convenient for operation.

The design of the guide column and bolt system realizes the combination of flexibility and stability. The user can adjust the inclination angle of the damping rod 21 according to the actual puncture path, effectively respond to the adaptability requirements of different body shapes or different puncture areas, and ensure the stability of the overall puncture path and the precise control of the operating feel.

Real-time feedback of ultrasonic images allows the operator to observe the puncture depth, path deviation and surrounding tissue structure of the bone puncture needle, further ensuring the safety of the puncture process.

[0072] How it works

[0073] Clamping stabilization function

[0074] The bracket 1 is in close contact with the patient's body through the clamping unit 4, so that the entire puncture device is fixed on the patient's body, providing a stable foundation to prevent the patient's movement from causing the puncture path to deviate. The clamping unit 4 relies on the clamping structure composed of the adjustment block 42, the paddle 43 and the return spring 46 to achieve the adjustment and stable clamping function, thereby providing a strong fixing effect.

[0075] Path adjustment and positioning function

[0076] The orientation unit 2 comprises a slider 23, a damping rod 21 and an orientation sleeve 22. The slider 23 can slide along the guide groove 14 and adjust the position of the puncture hole 231 through the first positioning bolt 24 so as to align it with the predetermined puncture area. The damping rod 21 is designed to be angle-adjustable. The user can adjust the inclination angle of the damping rod 21 through the second positioning bolt 27, thereby controlling the axial direction of the orientation sleeve 22 so that the puncture path meets the puncture path requirements expected by the user.

[0077] Ultrasonic guidance function

[0078] The ultrasonic probe is integrated on the slider 23 and connected to the ultrasonic device in real time to provide real-time puncture guidance images. The real-time ultrasonic image allows the doctor to monitor the puncture path, puncture needle depth, surrounding tissue conditions, and whether the bone puncture path is deviated in real time to ensure the safety of the puncture process.

[0079] Locking function

[0080] The bone puncture needle is fixed in the locking device, and the locking device adopts a mechanical structure for clamping operation. By rotating the puncture needle, the locking device is triggered to clamp the bone puncture needle, and the rotation path provided by the directional sleeve 22 is used to make the bone puncture needle realize stable puncture along the directional path, making the puncture process smoother and helping to resist the puncture instability caused by hand shaking.

[0081] How to use

[0082] Installation

[0083] The support 1 is placed on the patient's body where puncture is required, and is clamped and fixed by the clamping unit 4. The user can push the adjustment block 42 and operate the paddle 43 to achieve clamping, ensuring that the support 1 is stably fitted on the patient's body.

[0084] Adjust the puncture position

[0085] According to the position of the area to be punctured, the user adjusts the slider 23 so that the puncture hole 231 is aligned with the target puncture point. The first positioning bolt 24 is rotated to fix the slider 23, so that the puncture path is stable and reliable.

[0086] Adjust the puncture path angle

[0087] The angle of the damping rod 21 is adjusted using the second positioning bolt 27, thereby changing the tilt angle of the directional sleeve 22, so that the path of the puncture needle accurately matches the target puncture path. This process can be flexibly adjusted according to the different body shapes of patients or the actual puncture area.

[0088] Ultrasonic positioning inspection

[0089] Turn on the ultrasonic device, use the ultrasonic probe integrated in the slider 23 to observe the real-time image, check whether the puncture path deviates from the target area, and adjust the puncture path according to the real-time data to ensure accurate puncture positioning.

[0090] Piercing operation

[0091] Insert the bone puncture needle into the locking device, and use the locking device to clamp the puncture needle. The user rotates the bone puncture needle to allow the locking device to stably clamp the puncture needle, while the directional sleeve 22 assists in guiding the puncture path to ensure smooth puncture.

[0092] Release the lock after puncture is completed

[0093] After the puncture is completed, the user can rotate the puncture needle in the opposite direction to release the lock from the bone puncture needle, making it easier to remove the needle.

[0094] Disassembly device

[0095] Press the paddle 43 to release the clamping unit 4, and remove the entire bracket 1 and related devices. Under the action of the return spring 46, the adjustment block 42 automatically returns to the initial position, which is convenient for the next puncture operation or disassembly.

[0096] Precautions for use:

[0097] When the clamping unit 4 is clamped, it should be ensured that the device fits stably to avoid puncture deviation or patient discomfort due to insufficient clamping.

[0098] When using an ultrasound probe for puncture guidance, make sure the ultrasound device is properly connected and in working condition.
