[0002] A puncture device is a commonly used instrument for the treatment of kidney disease. It mainly consists of an adjustable bracket and a renal biopsy needle. It is primarily used to obtain kidney tissue samples for pathological diagnosis. The renal biopsy needle usually consists of a core and a tube. The needle body is relatively thin and comes in different specifications. The appropriate model can be selected according to the patient's specific situation. The material is mostly stainless steel, which has good rigidity and toughness, and can accurately puncture to the target site of the kidney while minimizing damage to surrounding tissues. Some biopsy needles are equipped with special sampling devices, such as ejector biopsy guns, which can quickly obtain tissue samples and improve the success rate and quality of sampling.

[0003] Chinese invention patent CN116898493A discloses a kidney biopsy device that can increase accuracy. However, in the actual process of kidney biopsy, it is necessary to first prepare kidney biopsy equipment, then adjust the patient's position and administer local anesthesia before the puncture and sampling operation can be performed. During the position adjustment and local anesthesia, the kidney biopsy needle is exposed, which leads to dust adhering to the needle tip, increasing the risk of wound infection for the patient after the puncture operation. Moreover, the exposed needle tip also poses a risk of scratching medical staff. Therefore, a puncture device for the treatment of kidney disease is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a puncture device for the treatment of kidney diseases, which has advantages such as protecting the needle tip of the renal biopsy needle. This solves the problem that during patient positioning and local anesthesia, the renal biopsy needle is exposed, which leads to dust adhering to the needle tip, increasing the risk of wound infection for the patient after the puncture operation. Moreover, the exposed needle tip also poses a risk of scratching medical staff.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a puncture device for the treatment of kidney disease, comprising a base, a mounting platform, a bracket, and a kidney biopsy needle, wherein a protective structure is provided on the bracket;

[0008] Furthermore, the connector includes a lever and an arc-shaped clip. The arc-shaped clip is fixedly installed on the outer surface of the cylindrical cover, the lever is slidably installed on the guide frame, and one end of the arc-shaped clip passes through the guide frame and is fixedly connected to the bottom of the lever.

[0009] Furthermore, another embodiment of the connector includes a linear driver, a toggle block, and an arc-shaped retainer. The toggle block is fixedly connected to the telescopic end of the linear driver, the toggle block and the arc-shaped retainer are fixedly connected, the arc-shaped retainer is fixedly connected to the cylindrical cover, and the linear driver is fixedly mounted on the guide frame.

[0010] Furthermore, the protective component includes an inner cylinder and multiple trapezoidal silicone blocks. The multiple trapezoidal silicone blocks are all fixedly installed on the inner peripheral wall of the inner cylinder and are centrally symmetrically distributed. One end of the inner cylinder is fixedly connected to the cylinder end cap.

[0011] Furthermore, the locking component includes an electric push rod and an arc-shaped brake plate.

[0015] This puncture device for treating kidney disease features a protective structure. When not in use, the protective shield completely covers the needle, preventing accidental contact by medical personnel or exposure to environmental contaminants, thus reducing the risk of infection. A trapezoidal silicone block elastically clamps the needle, preventing bending or breakage during preparation. This design secures the needle, reduces contact stress, and protects its sharpness. The connector offers both manual and electric drive options, catering to both precise manual control and automated operation needs, adapting to various medical scenarios. The locking mechanism effectively fixes the rotation angle of the outer ring, preventing the protective shield from wobbling and affecting needle accuracy during puncture. A limiting frame, fitted onto the outer ring, reduces radial wobbling during rotation, forming a dual-stabilizing structure in conjunction with the locking mechanism. Attached Figure Description

[0027] The locking component 57 includes an electric push rod and an arc-shaped brake plate. The telescopic end of the electric push rod passes through and extends into the interior of the arc-shaped mounting frame 52. The telescopic end of the electric push rod is fixedly connected to the arc-shaped brake plate. The electric push rod is fixedly mounted on the L-shaped bracket 53. The electric push rod of the locking component 57 pushes the arc-shaped brake plate, controls the arc-shaped brake plate to press the bracket 3 and fix the outer ring 51, prevents the outer ring 51 from shaking during puncture, and ensures the accuracy of the needle.

[0028] In addition, the limiting frame 58 is fixedly installed on the bracket 3. The limiting frame 58 is sleeved on the outer surface of the outer ring 51. The limiting frame 58 restricts the rotation range of the outer ring 51 to avoid excessive rotation.

[0029] Using the above technical solution, the outer ring 51 can rotate on the bracket 3, driving the arc-shaped mounting frame 52, the L-shaped bracket 53 and the guide frame 54 to rotate as a whole, so that the protective cover 56 is aligned with the needle tip of the renal biopsy needle 4, thereby fitting the protective cover 56 onto the needle tip of the renal biopsy needle 4. Then, the connecting piece 55 is moved, and the protective cover 56 slides along the guide frame 54, so that the protective cover 56 covers the needle tip, preventing external contamination or accidental contact. After the needle tip of the renal biopsy needle 4 is protected, the electric push rod of the locking component 57 pushes the arc-shaped brake plate, so that the arc-shaped brake plate presses the bracket 3 and fixes the outer ring 51, preventing the outer ring 51 from shaking during puncture and ensuring the positioning accuracy of the needle tip. The limiting frame 58 restricts the rotation range of the outer ring 51 to avoid excessive rotation.

[0030] Example 3: Please refer to Figure 1-7Based on Embodiment 2, the protective cover 56 includes a cylindrical cover 561, a cylindrical end cap 562, and a protective element 563. The cylindrical end cap 562 is fixedly installed at one end of the cylindrical cover 561. A rectangular groove is provided on the cylindrical cover 561 to facilitate the passage of the renal biopsy needle 4. The protective element 563 is fixedly installed on one side of the cylindrical end cap 562 and is used to protect the renal biopsy needle 4.

[0031] The connector 55 includes a lever and an arc-shaped clip. The arc-shaped clip is fixedly installed on the outer surface of the cylindrical cover 561. The lever is slidably installed on the guide frame 54. One end of the arc-shaped clip passes through the guide frame 54 and is fixedly connected to the bottom of the lever, achieving a manual control mode. The protective cover 56 is controlled to slide by manually pushing the lever, which is suitable for fine adjustment.

[0032] Alternatively, another embodiment of the connector 55 includes a linear driver, a lever, and an arc-shaped clip. The lever is fixedly connected to the telescopic end of the linear driver, the lever and the arc-shaped clip are fixedly connected, the arc-shaped clip is fixedly connected to the cylindrical cover 561, and the linear driver is fixedly mounted on the guide frame 54 to achieve electric control mode, automatically drive the protective cover 56, reduce human operation error, and improve efficiency.

[0033] In addition, the protective component 563 includes an inner cylinder and multiple trapezoidal silicone blocks. The multiple trapezoidal silicone blocks are fixedly installed on the inner circumferential wall of the inner cylinder and are centrally symmetrically distributed. One end of the inner cylinder is fixedly connected to the end cap 562. The end cap 562 and the cylindrical cover 561 form a closed space to isolate the needle from the outside. The inner cylinder and trapezoidal silicone blocks of the protective component 563 elastically clamp the needle, buffer external force and keep the needle stable, preventing the needle from shifting or being damaged before puncture.

[0034] Using the above technical solution, the end cap 562 and the cylindrical cover 561 form a closed space, isolating the needle from the outside world, achieving the effect of protection and dust prevention. The inner cylinder of the protective component 563 and the trapezoidal silicone block clamp the needle elastically, buffering external force and keeping the needle stable, preventing the needle from shifting or being damaged before puncture. It is also suitable for fine adjustment by manual pushing and reduces human operation error and improves efficiency by pushing with a linear actuator.

[0035] The working principle of the above embodiments is as follows:

[0036] In use, the outer ring 51 of this puncture device for treating kidney disease can rotate on the bracket 3, causing the arc-shaped mounting frame 52, the L-shaped bracket 53 and the guide frame 54 to rotate as a whole, so that the protective cover 56 is aligned with the needle tip of the kidney biopsy needle 4, thereby fitting the protective cover 56 onto the needle tip of the kidney biopsy needle 4. Then, the connector 55 is moved manually or driven by a linear actuator, and the protective cover 56 slides along the guide frame 54, so that the protective part 563 of the protective cover 56 covers the needle tip, and the trapezoidal silicone block clamps the needle tip to prevent external contamination or accidental contact.

[0037] Reverse movement of connector 55 causes protective cover 56 to retract from needle tip, exposing puncture end, which is convenient for doctor to operate;

[0038] After the protection of the kidney biopsy needle 4 is completed, the electric push rod of the locking component 57 pushes the arc-shaped brake plate, so that the arc-shaped brake plate presses the bracket 3 and fixes the outer ring 51 to prevent the outer ring 51 from shaking during puncture and to ensure the positioning accuracy of the needle. The limiting frame 58 restricts the rotation range of the outer ring 51 to avoid excessive rotation.

[0039] The cylindrical end cap 562 and the cylindrical cover 561 form a closed space to isolate the needle from the outside world, achieving the effect of protection and dust prevention. The inner cylindrical part and the trapezoidal silicone block of the protective part 563 clamp the needle elastically, buffer external force and keep the needle stable, preventing the needle from shifting or being damaged before puncture. It is suitable for fine adjustment by manual pushing and reduces human operation error and improves efficiency by pushing with a linear driver.
