Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a catheter device for interventional surgery of neurovascular diseases. Background Technology

[0002] In interventional neurosurgical procedures for cerebrovascular diseases, catheters are essential and critical instruments. They come in a wide variety of types and precise specifications, requiring rapid and accurate selection or replacement during the procedure based on the patient's condition. Currently, common catheter storage devices often employ simple storage boxes or multi-compartment trays. While these provide basic storage functionality, they still have significant shortcomings in the actual surgical environment: for example, they are not convenient to use, cannot quickly locate the target catheter, are prone to contamination from repeated opening and closing, and lack effective mechanisms to prevent accidental contact and provide zoned protection. Especially during high-intensity, high-precision surgeries, traditional devices struggle to achieve rapid catheter identification and aseptic handling, increasing surgical preparation time and potentially impacting surgical safety and efficiency due to incorrect catheter selection or contamination.

[0003] In addition, some existing catheter storage devices have complex structures and rely on electric or electronic control, resulting in problems such as high failure rate, high maintenance cost and poor environmental adaptability. In the special environment of the operating room, a sterile storage and rapid delivery device that is purely mechanical, simple in structure and intuitive to operate is more practical and reliable.

[0004] Therefore, how to develop a catheter device for interventional neurosurgical cerebrovascular disease that enables the classified storage, rapid retrieval, and aseptic protection of catheters, with a simple and reliable structure, intuitive and convenient operation, and no need for any electrical components, significantly improving the efficiency and safety of catheter management during surgery, has become a technical problem that urgently needs to be solved by researchers in this field. Summary of the Invention

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] like Figure 1-10As shown, a catheter device for interventional neurosurgical procedures for cerebrovascular diseases includes a housing 1, a rotating chamber 2, a press-and-telescopic assembly 3, a receiving box 4, a lifting assembly 5, and a handle insertion assembly 6. The housing 1 includes an upper cover 101, a lower cover 102, and a conical base 103. The conical base 103 has a cavity structure with an open top and is threaded to the bottom of the lower cover 102. A central shaft 7 is vertically fixed at the center of the lower cover 102. The rotating chamber 2 is rotatably fitted onto the central shaft 7. The central hole 1011 of the upper cover 101 is rotatably fitted onto the first positioning ring 201 at the top of the rotating chamber 2. The upper cover 101 is fixedly connected to the lower cover 102 via the handle insertion assembly 6. The central shaft 7 is a tubular structure with openings at both ends. The lower cover 102 has a through hole at its center that communicates with the central shaft 7. The press-and-telescopic assembly 3 is slidably connected to the inner cavity of the central shaft 7, and the telescopic end of the press-and-telescopic assembly 3 extends into the inner cavity of the conical base 103. The rotating chamber 2 has multiple first baffles 202 arranged at equal angles inside. The first baffles 202 divide the inner cavity of the rotating chamber 2 into multiple independent storage cavities 203. Multiple receiving boxes 4 are slidably embedded in the storage cavities 203. The lifting assembly 5 is located at the bottom end of the press-and-telescopic assembly 3 and is located in the inner cavity of the conical base 103. The top of the lifting assembly 5 passes through the first clearance hole 1021 opened in the lower cover 102 and is used to abut against the receiving box 4 at the corresponding position.

[0022] Specifically, the upper cover 101 also includes an upper cover body 1012, a first positioning skirt 1013, a first positioning groove 1014, a wire take-up port 1015, and a sealing door assembly 1016. The upper cover body 1012 covers and connects to the top of the rotating chamber 2. The first positioning skirt 1013 is disposed on the bottom periphery of the upper cover body 1012 for wrapping and positioning the upper cover body 1012 to the top of the rotating chamber 2. The bottom of the upper cover body 1012 is provided with six first positioning grooves 1014 at equal angles for cooperating with the elastic structure at the top of the rotating chamber 2 to achieve rotational positioning. The wire take-up port 1015 is opened on the top of the upper cover body 1012, and its position corresponds to the first clearance hole 1021. The sealing door assembly 1016 is hinged to one side of the wire take-up port 1015.

[0023] Specifically, the sealing door assembly 1016 includes a sealing door body 10161, a limiting groove 10162, a limiting block 10163, a magnet 10164, a rebound device 10165, and a handle 10166. The limiting block 10163 is disposed on the side of the sealing door body 10161 away from its hinge end. The limiting groove 10162 is formed on the upper cover body 1012 at a position that matches the limiting block 10163. When the sealing door body 1016... When the cover is placed on the wire outlet 1015, the limiting block 10163 is fitted and connected to the limiting groove 10162, the rebounder 10165 is embedded in the center of the limiting groove 10162, two magnet blocks 10164 are symmetrically arranged on both sides of the bottom of the limiting groove 10162, the limiting block 10163 is provided with the same number of magnet blocks 10164, and the handle 10166 is located on the top of the sealing door body 10161.

[0024] Specifically, the rebound device 10165 is used to release the sealing door body 10161 upon pressing. It cooperates with the magnet 10164 located on the limiting groove 10162 and the limiting block 10163 to reliably limit the sealing door body 10161 within the groove of the suture port 1015, effectively preventing accidental opening and providing a sealed storage environment for the catheter used in interventional surgery. To open, simply press down on the sealing door body 10161, and the rebound device 10165 will spring it open on one side, allowing the user to fully open the sealing door. Furthermore, the handle 10166 on the sealing door body 10161 can assist in opening the door if the rebound device 10165 malfunctions, ensuring smooth removal of the surgical catheter without affecting the surgical procedure.

[0025] Specifically, the lower cover 102 also includes a lower cover body 1022, a second positioning skirt 1023, and a second positioning groove 1024. The second positioning skirt 1023 is disposed on the top periphery of the lower cover body 1022 and is used to wrap around and position the bottom of the rotating cabin 2. The top of the lower cover body 1022 is provided with six second positioning grooves 1024 at equal angles, which are used to cooperate with the elastic structure at the bottom of the rotating cabin 2 to achieve rotational positioning. The positions of the second positioning grooves 1024 correspond to the first positioning grooves 1014.

[0026] Specifically, the handle insertion assembly 6 includes a grip portion 601, an elastic limiting buckle 602, and a limiting frame 603. The grip portion 601 is fixedly connected to one side of the upper cover body 1012. The limiting frame 603 is disposed on the lower cover body 1022 at a position corresponding to the grip portion 601. The elastic limiting buckle 602 is disposed at the bottom of the grip portion 601 and is used to insert and snap together with the limiting frame 603.

[0027] Specifically, the handle insertion assembly 6 is used to achieve the alignment connection between the upper cover 101 and the lower cover 102, so that the first positioning groove 1014 provided at the bottom of the upper cover 101 corresponds to the second positioning groove 1024 provided at the top of the lower cover 102, and together with the spring positioning beads 205 provided at the top and bottom of the rotating chamber 2, they assist in the positioning of the rotating chamber 2; when any storage cavity 203 of the rotating chamber 2 rotates to the position corresponding to the sealing door assembly 1016, the spring positioning beads 205 pop out and respectively lock into the first positioning groove 1014 and the second positioning groove 1024, and the user can feel obvious resistance during the rotation operation, so as to accurately judge whether the rotating chamber 2 is in place; in addition, the grip part 601 in the handle insertion assembly 6 can also be used as a hand-held part, making it convenient for the user to hold and rotate the rotating chamber 2.

[0028] Specifically, the rotating chamber 2 further includes a second positioning ring 204 and spring positioning beads 205. The two second positioning rings 204 are respectively fixedly disposed at the top and bottom of the rotating chamber 2, and six spring positioning beads 205 are evenly spaced on each second positioning ring 204. The positions of the spring positioning beads 205 match the first positioning groove 1014 and the second positioning groove 1024. The outer surface of the rotating chamber 2 is provided with friction protrusions 206 to facilitate manual rotation operation. The bottom of the rotating chamber 2 is provided with a second clearance hole 208 that matches the number of the receiving boxes 4.

[0029] Specifically, the top of the first positioning ring 201 is provided with text markings 207, and the position and number of the text markings 207 correspond to the storage cavity 203.

[0030] Specifically, the container 4 is provided with multiple second baffles 401 at equal intervals, which divide the interior of the container 4 into multiple independent storage spaces.

[0031] Specifically, each container 4 is divided into multiple independent storage spaces, allowing users to store multiple catheters of the same type for interventional surgery in a single container. This design can cope with emergencies such as catheter damage or contamination during surgery or the need to temporarily replace the same type of catheter due to changes in the surgical plan, avoiding interruption of surgery due to lack of spare catheters, thereby ensuring the continuity and safety of the surgical procedure.

[0032] Specifically, the press-and-retract assembly 3 includes a pressure rod 301, a cam 302, a guide block 303, a first connecting rod 304, a second connecting rod 305, a lifting plate 306, a first guide rod 307, a second guide rod 308, a spring 309, a pressure cap 310, and a limiting ring 311. The guide block 303 is fixedly connected to the bottom of the inner cavity of the central shaft 7 and together with the inner cavity wall of the central shaft 7, forms a guide groove 312. The pressure rod 301 is slidably connected in the guide groove 312. One end of the first connecting rod 304 is threadedly fastened to the top of the pressure rod 301, and the other end of the first connecting rod 304 is fixedly connected to the pressure cap 310. The diameter of the first connecting rod 304 is smaller than the diameter of the pressure rod 301. The limiting ring 311 is sleeved on the first connecting rod 304 and threadedly connected to the top opening of the central shaft 7. The cam 309, the first connecting rod 300, the second connecting rod 301, the first connecting rod 302, the second connecting rod 303, the first connecting rod 304, the second connecting rod 305, the lifting plate 306, the first guide rod 307, the second guide rod 308, the spring 309, the pressure cap 310, and the limiting ring 311 is sleeved on the first connecting rod 304 and threadedly connected to the top opening of the central shaft 7. The cam 309, the first connecting rod 300, the second connecting rod 302, the first connecting rod 304, the second connecting rod 305, the first connecting rod 306, the second connecting rod 307, the second connecting rod 308, the spring 309, the pressure cap 2. A rotatable sliding connection is made in the inner cavity of the central shaft 7 and slides with the guide groove 312. The cam 302 engages with the protruding teeth at the bottom of the pressure rod 301 to achieve alternating pressing and positioning. One end of the second connecting rod 305 is movably inserted into the limiting hole at the bottom of the cam 302, and the other end of the second connecting rod 305 is fixedly connected to the lifting plate 306. The first guide rod 307 and the second guide rod 308 are both fixedly connected to the bottom of the inner cavity of the conical base 103. The lifting plate 306 is slidably sleeved on the first guide rod 307 and the second guide rod 308. The spring 309 is sleeved on the first guide rod 307, and its two ends abut against the bottom of the inner cavity of the lifting plate 306 and the conical base 103, respectively. The lifting assembly 5 is fixedly connected to the side of the lifting plate 306 near the first clearance hole 1021.

[0033] Specifically, the conical base 103 not only helps improve the overall stability of the device, but its top-opening cavity structure can also seal the first clearance hole 1021 at the bottom of the lower cover 102 and the second clearance hole 208 at the bottom of the receiving box 4, effectively preventing dust from entering the device and avoiding contamination of the interventional surgical catheters stored therein. In addition, the conical base 103 and the lower cover 102 are connected by a threaded detachable connection, which makes it convenient for users to maintain the internal pressing telescopic component 3 and lifting component 5, and to clean the inside of the device.

[0034] Specifically, the lifting assembly 5 includes a connecting plate 501, a mounting base 502, and a lifting rod 503. The connecting plate 501 is integrally formed with the side of the lifting plate 306 near the first clearance hole 1021. The mounting base 502 is fixedly connected to the top of the connecting plate 501, and the bottom end of the lifting rod 503 is threadedly connected to the mounting base 502.

[0035] Specifically, the press-and-retract component 3 allows the user to control the ejection or retraction of the receiving box 4 by repeatedly pressing the cap 310, and its working mechanism is similar to the press-and-switch principle of a telescopic ballpoint pen. In the initial state, the lifting rod 503 is located in the inner cavity of the conical base 103, and the device is in the closed position. When the pressure cap 310 is pressed for the first time, the pressure rod 301 moves downward, pushing the cam 302 to rotate and move within the guide groove 312 formed by the guide block 303. When the cam 302 rotates to engage with the locking groove at the end of the guide block 303, the cam 302 is locked in this position. At the same time, the cam 302 drives the lifting plate 306 to move downward through the second connecting rod 305, compressing the spring 309 sleeved on the first guide rod 307. The spring 309 accumulates elastic potential energy to provide power for the subsequent upward movement. During this process, the lifting rod 503 of the lifting assembly 5 also descends and remains inside the conical base 103, and the device returns to the initial closed state.

[0036] When the cap 310 is pressed for the second time, the cam 302 disengages from its original locking position and rotates back to its original position, thus releasing the lock. At this time, the compressed spring 309 releases its elastic potential energy, pushing the lifting plate 306 upward along the first guide rod 307 and the second guide rod 308. This, in turn, drives the cam 302 to move upward as a whole through the second connecting rod 305. The upward movement of the lifting plate 306 pushes the lifting rod 503 in the lifting assembly 5 to move upward. The lifting rod 503 passes through the first clearance hole 1021 of the lower cover 102 and the second clearance hole 208 at the bottom of the receiving box 4, pushing the target receiving box 4 upward from the storage cavity 203, so that its upper part is exposed from the wire extraction port 1015, making it easy for the user to take out the conduit stored therein.

[0037] Specifically, the press-and-retract component 3 uses a purely mechanical structure to achieve the lifting function without the need for any electrical components. This not only makes the structure simple and the operation reliable, but also enhances the durability and applicability of the device.

[0038] Specifically, the limiting ring 311 restricts the upward displacement of the pressure rod 301 when it slides within the central shaft 7, preventing it from detaching from the top, thereby ensuring the stability and reliability of the pressure rod's movement.

[0039] Specifically, this invention uses a direct rotation of the rotating chamber 2 to enable the rapid selection of different types of catheters stored in different storage cavities 203 within the rotating chamber 2. The direct force applied to the rotation of the rotating chamber 2 makes its rotation less strenuous. In addition, the text markings 207 on the top of the first positioning ring 201 allow for quick determination of the desired catheter position. Furthermore, the spring positioning bead 205, along with the first positioning groove 1014 and the second positioning groove 1024, assists the user in quickly and accurately positioning the catheter.

[0040] The process of using this invention is as follows: First, the user holds the grip part 601 of the handle insertion assembly 6 and directly rotates the rotating chamber 2. The friction protrusions 206 on its outer surface enable effortless operation. At the same time, the text markings 207 on the top of the first positioning ring 201 allow for a preliminary judgment of the area where the target conduit is located. When the rotating chamber 2 rotates to the point where the target receiving box 4 approaches the sealing door assembly 1016, the spring positioning beads 205 respectively engage with the first positioning groove 1014 of the upper cover 101 and the second positioning groove 1024 of the lower cover 102, generating a noticeable resistance and achieving precise positioning. Secondly, the user presses the sealing door body 10161, the rebound device 10165 pops it up, and then the sealing door is fully opened by the handle 10166, so that the wire outlet 1015 is exposed. Next, by continuously pressing the cap 310, the telescopic assembly 3 is driven to press: during the first press, the cam 302 engages with the end slot of the guide block 303, and the spring 309 is compressed and stores energy; during the second press, the cam 302 disengages, the spring 309 is released and pushes the lifting plate 306 upward, which in turn pushes the corresponding receiving box 4 out of the storage cavity 203 through the lifting rod 503, so that its upper part is exposed from the wire take-up port 1015; Then, the user takes the required tube from the ejected container 4 to complete the retrieval operation; Finally, press the cap 310 again to make the cam 302 re-engage into the end of the guide block 303, driving the lifting plate 306 and the lifting rod 503 to descend and reset. The receiving box 4 is retracted into the storage cavity 203. Then, close the sealing door assembly 1016.
