Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a rapid positioning device for a cricothyroid membrane puncture needle. Background Technology

[0002] Cricothyroidotomy is a crucial emergency technique for critical illnesses such as acute laryngeal obstruction, and the accurate location of the puncture site directly determines the success or failure of the rescue. Currently, clinical practice mainly relies on medical staff to locate the puncture site by palpating anatomical landmarks in the anterior neck. However, in complex situations such as obese patients, neck swelling, unclear anatomical structures, or external trauma causing damage to the neck structure, surface landmarks are difficult to identify, and the accuracy of the puncture site highly depends on the operator's experience, which can easily lead to puncture failure or delay in rescue.

[0003] Existing auxiliary devices mostly focus on mechanical fixation or static template comparison, which is difficult to adapt to individual patient differences and changes in body position, and cannot effectively solve the problem of target visualization under complex body surface conditions. Currently, there are no auxiliary devices that use laser irradiation for puncture point localization. The cricothyroid membrane has natural light transmittance, and lasers can effectively penetrate this membrane to form a clear light-transmitting area. This physiological characteristic provides an ideal tissue window for laser localization. Optical irradiation technology uses an optical guide system to focus the laser onto the cricothyroid membrane to form a visible light spot, transforming traditional palpation localization into intuitive optical guidance, significantly reducing reliance on operator experience, and providing a new technical approach for precise localization.

[0004] However, applying this technology to cricothyroid membrane puncture still faces challenges. It requires ensuring stable attachment of the device at the emergency scene to prevent laser marking from shifting due to device movement; designing a flexible and adjustable robotic arm to adapt to different patients' neck shapes and ensure accurate laser projection onto the target point; and simultaneously balancing device portability and operational efficiency. Therefore, developing a device that integrates stable support, flexible adjustment, and optical positioning assistance to improve positioning efficiency and operational convenience during cricothyroid membrane puncture is of significant clinical value in increasing puncture success rates. Summary of the Invention

[0005] Therefore, it is necessary to provide a rapid positioning device for cricothyroid membrane puncture needles to address the aforementioned technical problems. This device utilizes the excellent light transmittance of the cricothyroid membrane to achieve precise identification and puncture guidance through laser irradiation. A stable support bracket for the irradiation lamp is specifically designed for this purpose. Specifically, the device is stably attached to the ground, table, or wall through a fixed base assembly. Relying on the rotational function of the first and second movable arms, as well as the sliding and rotational adjustment of the auxiliary movable arms, the position and angle of the fixing clamp and laser lamp assembly can be flexibly adjusted. In emergency scenarios, even if the patient has complex conditions such as obesity, edema, unclear anatomical landmarks, or structural damage caused by external trauma, the puncture position can still be effectively and conveniently located through laser irradiation, thereby achieving rapid and accurate positioning, improving the puncture success rate and operational efficiency.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention. Example 1:

[0021] Please refer to Figure 1 - Figure 7 A rapid positioning device for a cricothyroid membrane puncture needle, comprising: The mounting base 1 has suction cups at its bottom, allowing it to firmly adhere to the ground, tabletop, or wall surface, providing a stable foundation for the equipment or components supported above. Specifically, the mounting base 1 includes a stabilizing plate 7, which is V-shaped. The V-shape helps to better conform to the tabletop or wall surface and possesses good stability, similar to the stabilizing properties of a triangle, greatly increasing the stability of the adhesion and ensuring that the mounting base 1 remains firmly fixed in various environments, preventing shaking or displacement.

[0022] A suction cup is positioned below the stabilizing plate 7, its strong suction power firmly gripping the contact surface and providing reliable suction for the entire mounting assembly 1. The mounting body 12 is located at the upper center of the stabilizing plate 7. The mounting body 12 is the core load-bearing component of the mounting assembly 1, used for installing and supporting other equipment or components. To facilitate position adjustment of the mounting body 12 on the stabilizing plate 7, a connecting slide rail 13 is fixedly connected to the upper end of the stabilizing plate 7 opposite to the mounting body 12. The mounting body 12 is slidably connected to the stabilizing plate 7 via the connecting slide rail 13. This sliding connection allows the mounting body 12 to move flexibly on the stabilizing plate 7, adjusting to a suitable position according to actual needs, greatly improving the flexibility and convenience of use.

[0023] However, a sliding connection alone is insufficient to ensure the stable fixation of the seat body 12 after it has been adjusted to the appropriate position. Therefore, a limiting block 14 is fixedly connected to the upper end of the stabilizing plate 7, located on both sides of the seat body 12. A spring-loaded locking assembly 15 is embedded inside the limiting block 14, and the spring-loaded locking assembly 15 engages with the side of the seat body 12, forming a reliable locking mechanism. The spring-loaded locking assembly 15 is threadedly connected to the limiting block 14, ensuring both the secure installation of the spring-loaded locking assembly 15 and facilitating subsequent disassembly and maintenance. Multiple positioning holes 16 are evenly distributed on the side of the seat body 12. When the seat body 12 slides to the desired position, the spring-loaded locking assembly 15 engages with the seat body 12 through the positioning holes 16, thus fixing the seat body 12 on the stabilizing plate 7. This design allows the fixed seat assembly 1 to flexibly adjust the position of the seat body 12 and ensure its stability after adjustment, providing a reliable guarantee for the normal operation of the equipment.

[0024] The first movable arm 2 is positioned above the fixed base assembly 1, with its lower end rotatably connected to the fixed base assembly 1. Furthermore, a connecting seat 17 is fixedly connected to the upper end of the base body 12. The end of the first movable arm 2 away from the second movable arm 3 is rotatably connected to the connecting seat 17. An adjusting cylinder 18 is provided inside the first movable arm 2, near its end. A limiting friction post 19 is provided at the end of the adjusting cylinder 18 near the end of the first movable arm 2. The limiting friction post 19 is threadedly connected to the first movable arm 2. The end of the limiting friction post 19 away from the adjusting cylinder 18 extends to the inner side of the end of the first movable arm 2. Rotating the adjusting cylinder 18 allows the limiting friction post 19 to extend towards the end of the first movable arm 2, thus limiting the rotation of the end of the first movable arm 2 and preventing accidental rotation during use.

[0025] The second movable arm 3 is located on one side of the first movable arm 2, and one end of the second movable arm 3 is rotatably connected to the end of the first movable arm 2 away from the fixed base 1. Through this rotatable connection, the second movable arm 3 can rotate flexibly relative to the first movable arm 2 to adjust its angle and position.

[0026] The fixing clamp 4 is located at the end of the second movable arm 3 away from the first movable arm 2. The fixing clamp 4 is used to clamp and fix the cricothyroid membrane puncture needle. An auxiliary movable arm 5 is located on one side of the second movable arm 3, and one end of the auxiliary movable arm 5 is rotatably connected to the second movable arm 3. The laser light assembly 6, detachably mounted at the end of the auxiliary movable arm 5 furthest from the second movable arm 3, not only ensures the flexibility and adjustability of the laser light assembly 6 during use but also facilitates quick disassembly and replacement when needed, greatly improving the practicality and ease of maintenance of the device. The laser light assembly 6 emits a laser beam into the patient's neck. Utilizing the excellent light transmittance of the cricothyroid membrane, the laser penetrates the soft tissue of the neck, forming a clear light-transmitting area at the cricothyroid membrane, providing intuitive optical guidance for puncture positioning. The laser light assembly 6 is the key structure of this device for achieving laser irradiation and positioning of the cricothyroid membrane. It uses a commercially available high-brightness laser flashlight as the core light source, featuring high brightness, strong focusing, and clear beam boundaries. By exciting a phosphor to generate white laser light, its beam diameter is controlled within the range of 5-15 mm, effectively penetrating the soft tissue of the neck and forming a clear light-transmitting area at the cricothyroid membrane, providing accurate optical guidance for puncture positioning.

[0027] Specifically, the auxiliary movable arm 5 includes a sliding frame 23, which is sleeved on the outside of the second movable arm 3. The sliding frame 23 can slide along the length of the second movable arm 3. A first connecting arm 24 is rotatably connected to the side of the sliding frame 23. A second connecting arm 25 is rotatably connected to the end of the first connecting arm 24 away from the sliding frame 23. A third connecting arm 26 is rotatably connected to the end of the second connecting arm 25 away from the first connecting arm 24. Specifically, the laser light group 6 includes a connecting sleeve 27 and a laser light 28. The connecting sleeve 27 is connected to the third connecting arm 26, and the laser light 28 is inserted into the inside of the connecting sleeve 27.

[0028] Furthermore, a connector 29 is provided between the third connecting arm 26 and the connecting sleeve 27. The connector 29 includes two rotatably connected discs. One disc is provided with a positioning protrusion, and the other disc is provided with a positioning groove. The positioning protrusion and the positioning groove are connected in cooperation. This structure allows for convenient adjustment of the irradiation angle of the laser lamp 28 and maintains stability after adjustment.

[0029] Furthermore, the contact area between the sliding frame 23 and the second movable arm 3 is provided with an anti-slip pad to prevent the sliding frame 23 from moving on its own when it is not needed to slide; the sliding frame 23 and the first connecting arm 24, the first connecting arm 24 and the second connecting arm 25, and the second connecting arm 25 and the third connecting arm 26 are all connected by a damping shaft, so that the rotation between each connecting arm has a certain resistance, making it easier for medical staff to adjust the angle and maintain stability.

[0030] Through the above structural design, the fixed base 1 can be stably attached to the ground, tabletop, or wall. By utilizing the rotation of the first movable arm 2 and the second movable arm 3, as well as the sliding and rotation of the auxiliary movable arm 5, the position and angle of the fixed clamp 4 and the laser light group 6 can be flexibly adjusted. Under harsh conditions, the translucent irradiation method is used to form a clear light-transmitting area by utilizing the light transmittance of the cricothyroid membrane, which can effectively and conveniently locate the position, thereby quickly and accurately locating the puncture position and improving the success rate and efficiency of puncture. Example 2:

[0031] The rapid positioning device for the cricothyroid membrane puncture needle provided in Embodiment 1 has been further optimized, specifically, as follows: Figure 3 As shown, the suction cup includes a first plate 8 and a second plate 9. Both the first plate 8 and the second plate 9 are located below the stabilizing plate 7. The first plate 8 is located at the bend of the stabilizing plate 7, and the second plate 9 is located at the end of the stabilizing plate 7. The first plate 8 is fixedly connected to the stabilizing plate 7. The upper end of the second plate 9 is provided with a height adjustment rod 10. A limiting knob 11 is sleeved on the outside of the height adjustment rod 10. The limiting knob 11 is threadedly connected to the height adjustment rod 10. The limiting knob 11 is rotatably connected to the stabilizing plate 7. By rotating the limiting knob 11, the height of the second plate 9 can be adjusted to adapt to the undulations of different ground, countertop or wall surfaces, thereby improving the adsorption and fixation effect. Example 3:

[0032] The rapid positioning device for the cricothyroid membrane puncture needle provided in Embodiment 1 has been further optimized, specifically, as follows: Figure 5 As shown, the fixing clamp 4 includes a fixing frame 20, which is U-shaped. The open end of the fixing frame 20 faces away from the second movable arm 3. A clamping adjustment rod 21 is threadedly connected to one side of the open end of the fixing frame 20. By rotating the clamping adjustment rod 21, its length extending into the fixing frame 20 can be adjusted, thereby achieving clamping of cricothyroid membrane puncture needles of different specifications. An anti-slip protrusion 22 is provided on the inner side of the other side of the open end of the fixing frame 20. The anti-slip protrusion 22 can increase the friction between the fixing frame 20 and the puncture needle, thereby improving the clamping stability.
