Technical Field
[0001] This invention relates to the field of medical auxiliary equipment technology, specifically a lung puncture fixation device. Background Technology
[0002] In the medical field, lung biopsy is an important medical device widely used in the diagnosis and treatment of lung diseases, such as obtaining lung tissue samples for pathological analysis to accurately determine the condition.
[0003] Currently, the common method for performing lung biopsies is for medical staff to manually control the insertion of the needle into the patient's body. However, due to the complexity of the human lung structure and the diversity of lesion locations, to ensure that the needle can be inserted accurately into the lesion, medical staff often need to perform multiple needle insertions, and each time they must carefully adjust the insertion angle of the needle to ensure that the needle reaches the lesion accurately to the greatest extent possible.
[0004] However, due to the current lack of effective auxiliary devices to assist medical staff in performing this delicate procedure, they are forced to rely solely on their experience, feel, and memory of anatomical structures. This makes it difficult to ensure the precision of needle insertion angle and adjustment, often resulting in the needle failing to accurately reach the lesion. This necessitates frequent re-insertion, significantly increasing patient discomfort and pain, making the entire procedure time-consuming and laborious, reducing medical efficiency, and potentially posing additional risks of physical injury to the patient due to repeated needle insertions, thus impacting the patient's treatment experience and recovery process. Summary of the Invention

This device solves the aforementioned issues by allowing medical personnel to rely solely on their experience, feel, and memory of anatomical structures for needle insertion. This makes it difficult to ensure the precision of needle insertion angle and adjustment, often resulting in the needle failing to accurately reach the lesion. This necessitates frequent re-insertion, significantly increasing patient discomfort and pain, making the entire procedure time-consuming and laborious, reducing medical efficiency, and potentially causing additional physical damage to the patient due to repeated needle insertions, thus impacting the patient's treatment experience and recovery process.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0018] like Figures 1-8 As shown, the present invention provides the following technical solution: Example 1: A lung puncture fixation device includes a mounting base 1 and a needle 3; a crossbeam 2 is fixedly connected to one side of the upper end of the mounting base 1, and a slider 4 is slidably connected to the outer side of the crossbeam 2. A scale 10 is provided on one side of the slider 4, and an indicator block 11 is fixedly connected to the upper end of the slider 4. The indicator block 11 corresponds to the initial scale of the scale 10. A rotating block 5 is provided on the other side of the slider 4. The scale 10 and the rotating block 5 are fixedly connected by a rotating rod 14, and the rotating rod 14 is rotatably connected to the slider 4; a through hole 15 is provided inside the rotating block 5. The device includes a placement component 6, with the needle 3 placed inside the placement component 6. A toothed disc 13 is fixedly connected to the side of the rotating block 5 away from the slider 4 via a connecting post 16. Several slots 17 are evenly distributed on the outer side of the toothed disc 13, and a positioning component 7 is provided on one side of the toothed disc 13. By setting the scale 10, the rotating block 5, and the matching positioning component 7, the insertion angle and position of the needle 3 can be precisely adjusted and fixed, avoiding the needle 3 failing to reach the lesion due to angle deviation, greatly improving the puncture success rate and reducing the pain caused to the patient by repeated punctures. The placement component 6 includes a sleeve 61, which is movably inserted into the through hole 15. The needle 3 is movably inserted into the sleeve 61, and the diameter of the sleeve 61 matches that of the needle 3. A collar 62 is fixedly sleeved on the outer side of the upper end of the sleeve 61, and several insertion rods 63 are fixedly connected to the bottom end of the collar 62. The upper end of the rotating block 5 is provided with several slots 64 that match the insertion rods 63. The bottom ends of the insertion rods 63 are movably inserted into the slots 64 respectively. The sleeve 61 can be replaced according to the actual specifications of the needle 3 to ensure that the needle 3 is stably placed in the sleeve 61, thereby ensuring the stability of the needle 3 during the insertion process. The sleeve 61 can be disassembled by simply pulling the sleeve 61 upward and completely separating the insertion rods 63 from the slots 64. The replacement of the sleeve 61 is very convenient. The positioning component 7 includes two mounting blocks 71, which are fixed to the outside of the slider 4. A retaining strip 74 is rotatably connected between the two mounting blocks 71 via a rotating shaft 72. One end of the retaining strip 74 is movably locked in the corresponding slot 17. Torsion springs 73 are fixedly connected to both sides of the retaining strip 74 and the corresponding mounting blocks 71. The two torsion springs 73 are sleeved around the rotating shaft 72 and are movably inserted into the slot 17 via one end of the retaining strip 74, thereby preventing the rotating block 5 from rotating accidentally during puncture and ensuring the stability of the angle of the needle 3. Specifically, the center positions of the connecting column 16, rotating rod 14, rotating block 5, and dial 10 correspond to each other; In use, medical staff adjust the horizontal position of the needle 3 by sliding slider 4 according to the location of the lesion, so that the needle 3 is above the lesion. Then, they press one end of the retaining strip 74, which rotates along the rotating shaft 72. During this process, the torsion spring 73 is twisted, and the other end of the retaining strip 74 separates from the retaining groove 17 on the outside of the toothed disc 13. At this time, the restriction on the toothed disc 13 is released, thereby releasing the restriction on the rotating block 5. Then, by observing the scale 10 and the indicator block 11, the rotating block 5 is rotated to a suitable angle to adjust the insertion angle of the needle 3. After adjustment, the retaining strip 74 is released, and the retaining strip 74 returns to its initial state due to the rebound force of the torsion spring 73. The end is reinserted into the corresponding slot 17, thereby ensuring the adjustment angle of the toothed disc 13 and the rotating block 5. The rotation angle of the rotating block 5 is accurately set with the help of the scale 10, thereby precisely controlling the insertion direction of the needle 3. This avoids the needle 3 failing to reach the lesion due to angle deviation, greatly improving the puncture success rate and reducing the pain caused to the patient by repeated punctures. At the same time, the matching sleeve 61 can be replaced according to the actual specifications of the needle 3, ensuring that the needle 3 is stably placed in the sleeve 61, thereby ensuring the stability of the needle 3 during the insertion process. Simply pull the sleeve 61 upwards, and the insertion rod 63 is completely separated from the slot 64 to complete the disassembly of the sleeve 61. Replacing the sleeve 61 is very convenient.
[0019] Example 2: This example differs from Example 1 in that the technical solution includes: several side blocks 12 are evenly fixed on one side of the crossbeam 2; a limiting component 8 is provided on the side of the slider 4 near the side block 12; the limiting component 8 includes an opening 86, which is opened on one side of the slider 4; a connecting rod 82 is movably inserted into the upper end of the opening 86; a pressing block 81 is fixedly connected to the top of the connecting rod 82; the bottom end of the connecting rod 82 is movably inserted into a groove 85; the groove 85 is set on the bottom wall of the opening 86; a locking block 83 is fixedly sleeved on the outside of the connecting rod 82; a spring 84 is fixedly connected between the bottom end of the locking block 83 and the bottom wall of the opening 86; the spring 84 is sleeved around the connecting rod 82; and the locking block 83 is movably locked between two corresponding side blocks 12.
[0020] In use, medical staff press the pressing block 81, causing the connecting rod 82 to move the locking block 83 downwards, compressing the spring 84. The locking block 83 disengages from the two currently locked side blocks 12. At this time, the slider 4 can be slid along the crossbeam 2 to adjust the horizontal position of the needle 3. When the slider 4 moves to the appropriate position, the pressing block 81 is released, the spring 84 rebounds, and pushes the locking block 83 into the corresponding two side blocks 12, thus fixing the slider 4.
[0021] Example 3: The technical solution of this example, which differs from that of Example 2, also includes: a control component 9 is provided on one side of the needle 3. The control component 9 includes a base block 94, which is fixed on the outside of the rotating block 5. A lead screw 92 is rotatably connected to the upper end of the base block 94. An operating ring 93 is fixedly sleeved on the outside of the lead screw 92. A fixing block 91 is threadedly connected to the top of the lead screw 92. The fixing block 91 is fixedly connected to the outside of the needle 3.
[0022] In use, medical staff rotate the operating ring 93. Since the lead screw 92 is threadedly connected to the fixing block 91 and the fixing block 91 is fixed on the needle 3, rotating the operating ring 93 will drive the lead screw 92 to rotate, thereby causing the fixing block 91 to move along the axis of the lead screw 92, thus realizing the adjustment of the needle 3's entry and exit, so as to precisely control the depth of the needle 3 inserted into the patient's body, complete the lung puncture operation, ensure the stability of the needle 3's insertion, prevent the rebound phenomenon, and at the same time, fine-tune the entry and exit of the needle 3.
[0023] Example 4: The technical solution of this example, which differs from that of Example 3, further includes: several sets of auxiliary units are evenly arranged on the inner wall of the through hole 15. Each set of auxiliary units consists of three auxiliary components 18. Each auxiliary component 18 includes a recess 181, which is fixed on the inner wall of the through hole 15. A mounting groove 182 is provided on one side of the recess 181. A plug 184 is movably inserted into the mounting groove 182. The plug 184 matches the mounting groove 182. A compression spring 182 is fixedly connected between one side of the plug 184 and the inner wall of the mounting groove 182. A ball bearing 185 is embedded on the side of the plug 184 that extends out of the mounting groove 182.
[0024] When in use, when the needle 3 is inserted into the through hole 15, the outer side of the needle 3 is in contact with the outer side of several balls 185, and the balls 185 are in rolling connection with the outer side of the needle 3. When the needle 3 is inserted or withdrawn, the sliding connection between the needle 3 and the inner wall of the through hole 15 is transformed into a rolling connection with the balls 185. This can ensure the stability of the needle 3 and reduce the friction force on the needle 3, thereby preventing the needle 3 from being damaged or overheated due to excessive friction.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
