Description

Technical Field

[0001] This utility model relates to the field of wire guiding equipment technology, and more specifically, to a wire guiding operation platform with extension. Background Technology

[0002] In minimally invasive surgeries such as cardiovascular intervention and gastrointestinal endoscopy, the guidewire is the core instrument for establishing surgical access, and its operational precision directly affects the safety and treatment outcome. For example, in percutaneous coronary intervention, doctors need to guide the stent to the narrowed area of ​​the blood vessel using a guidewire. The entire process requires frequent retrieval and placement of the guidewire and related instruments, which places extremely high demands on the convenience and stability of the operating platform.

[0003] Currently used guidewire manipulation devices in clinical practice have the following main defects:

[0004] Inconvenient installation and storage: Existing guidewire frames are mostly fixed to the operating table and connected by bolts or welding. Disassembly and assembly are cumbersome when not used for special surgeries, and they occupy a lot of storage space when not in use, increasing the management cost of the operating room.

[0005] Insufficient operating space: Traditional platforms have a fixed area and cannot be flexibly expanded according to surgical needs. Guide wires, catheters and other instruments often need to be placed on a mobile instrument cart, which not only takes up surgical space, but may also prolong the instrument exchange time due to the long retrieval and placement path, increasing the risk of complications such as air embolism and sheath slippage (according to statistics, the instrument exchange process causes about 30.1% of puncture-related complications).

[0006] Poor adaptability: The existing equipment has a rudimentary height adjustment mechanism, which is difficult to meet the operating habits of doctors of different heights and cannot adapt to the needs of different surgical positions; at the same time, it lacks a dedicated hand support structure, and doctors are prone to hand fatigue when holding the guidewire for a long time, which may affect the accuracy of the operation.

[0007] Insufficient safety protection: When the guidewire is placed in direct exposure, it is easy to fall to the ground due to collision or accidental contact, increasing the risk of contamination; some hand rests are not ergonomically designed, which may cause wrist strain for doctors after prolonged use, and lack anti-slip measures, affecting the stability of operation. Utility Model Content

[0008] The purpose of this utility model is to provide an expandable guidewire operation platform to solve the problems mentioned in the background art, which are that existing guidewire frames are mostly fixed to the operating table and connected by bolts or welding. They are cumbersome to disassemble and assemble when not used for special surgery, and occupy a lot of storage space when not in use, which increases the management cost of the operating room.

[0009] To achieve the above objectives, this utility model provides a guidewire operating platform with extension, including a support plate. An operating platform is provided on the top of one side of the support plate. The operating platform is adjusted for lifting and lowering via a lifting adjustment component. An extension platform is connected to one side of the operating platform. The extension platform covers the upper part of the patient's body. The operating platform is located on one side of the patient's body. A push-pull plate is slidably connected to one end of the operating platform. A hand support plate is installed on the top of one end of the push-pull plate.

[0010] This setup uses a support plate as the basic positioning component, and the platform is quickly fixed by "inserting the support plate under the operating mattress"; the lifting and adjusting components drive the operating platform to move vertically and adjust the height; the extension platform connects with the operating platform to form an extension structure, covering the upper part of the patient's body to increase the placement area; the push-pull plate slides along the operating platform to adjust the hand support to a comfortable position for the doctor's hands.

[0011] Preferably, the expansion platform includes a first movable plate and a second movable plate, one side of the first movable plate is hinged to the second movable plate, and the other side of the first movable plate is hinged to the operating platform.

[0012] This setup expands the platform using a hinged structure of "first movable plate + second movable plate". The two plates can rotate around the hinge point. When unfolded, the two plates are flat, increasing the area for placing equipment; when folded, the two plates fit together, reducing the platform volume.

[0013] Preferably, the operating platform has an L-shaped structure, with a first guide groove installed on the bottom of one side of the operating platform, a support seat installed on the inner wall of the other side of the operating platform, a second guide groove installed on the support seat, a first guide strip installed on the top of one side of the push-pull plate, the first guide strip slidingly engaging with the first guide groove, and a second guide strip installed on the bottom of the other side of the push-pull plate, the second guide strip slidingly engaging with the second guide groove.

[0014] The L-shaped structure of this operating platform is adapted to the spatial layout of "patient's side + upper body"; the first guide groove and the first guide strip of the push-pull plate, and the second guide groove and the second guide strip form a "double guide sliding fit", which restricts the push-pull plate to move only in the horizontal direction and avoids deviation.

[0015] Preferably, the lifting adjustment component includes a fixed sleeve, a lifting rod is slidably disposed on the top of the fixed sleeve, one side of the top of the lifting rod is fixedly connected to the operating platform, and the bottom end of the fixed sleeve is fixedly connected to the support plate.

[0016] This feature involves fixing the lifting and adjusting components to the support plate, allowing the lifting rod to slide along the inner wall of the fixing sleeve. By "changing the extension length of the lifting rod through sliding," the operating platform is raised and lowered, forming a basic structure for height adjustment.

[0017] Preferably, a locking bolt is threaded on one side of the fixing sleeve, one end of the locking bolt abuts against the outer wall of the lifting rod, and a handle is installed on the other end of the locking bolt.

[0018] This feature allows the locking bolt to engage with the threaded fixing sleeve. When tightened, one end of the bolt presses against the outer wall of the lifting rod, locking the position of the lifting rod through friction. The handle increases the gripping area of ​​the bolt, making it convenient for doctors to manually and quickly tighten it.

[0019] Preferably, a locking nut is installed on the locking bolt.

[0020] This feature allows the locking nut and locking bolt to engage with each other via threads. When tightened, the nut fits snugly against the outer wall of the fixing sleeve. The "double thread locking" prevents the locking bolt from loosening due to surgical vibrations, thus enhancing locking stability.

[0021] Preferably, the top of the hand support plate has an inwardly concave arc surface structure.

[0022] The inwardly concave arc structure of the wrist rest conforms to the natural curvature of the human wrist, ensuring even force distribution when the wrist is placed, which is in line with ergonomic design.

[0023] Preferably, both ends of the first guide groove are provided with limiting blocks, the limiting blocks are integrally formed with the operating platform, and the inner side of the limiting blocks is provided with a buffer pad to limit the sliding stroke of the push-pull plate.

[0024] This feature integrates the limiting blocks at both ends of the first guide groove with the operating platform, physically preventing the push-pull plate from sliding beyond its travel range; the buffer pad inside the limiting block absorbs the impact force of the push-pull plate through elastic deformation, reducing the impact.

[0025] Preferably, the outer wall of the lifting rod is provided with scale lines along its length, and the top outer side of the fixing sleeve is provided with a pointer, which corresponds to the scale lines to indicate the lifting height of the operating platform.

[0026] This setting marks the specific height value on the scale line on the outer wall of the lifting rod, and the pointer on the top of the fixed sleeve serves as a reference. The actual lifting height of the operating platform is displayed intuitively by "aligning the pointer with the scale".

[0027] Preferably, the top of the curved surface of the hand rest is provided with several anti-slip protrusions, which are made of medical-grade silicone and are evenly distributed in an array.

[0028] The medical-grade silicone anti-slip protrusions on the curved top of the hand rest increase the friction of the contact surface and prevent the hand from slipping; the silicone material is biocompatible and disinfection resistant, and the evenly distributed array ensures balanced force distribution.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] This expandable guidewire operating platform requires no bolts or welding for fixation; the support plate can be directly inserted under the operating mattress for positioning, adapting to different height requirements. After use, it can be quickly removed for sterilization and compactly stored when not in use, solving the problems of cumbersome disassembly and assembly and space occupation of traditional guidewire frames, and reducing the cost of operating room instrument management.

[0031] The articulated extension platform can be flexibly deployed to cover the upper part of the patient's body and work in conjunction with the lateral operating platform to simultaneously hold guidewires, catheters and other instruments without the need for an additional mobile instrument cart; it shortens the instrument retrieval and placement path, reduces the risk of complications caused by excessively long exchange time, and avoids contamination or omission caused by scattered instrument placement.

[0032] The height adjustment component achieves precise height control through scale lines and pointers, adapting to doctors of different heights and surgical positions; the push-pull plate can be flexibly extended and retracted, and the curved structure of the hand support plate conforms to the shape of the wrist, reducing hand fatigue and wrist strain during long-term operation, indirectly improving the accuracy of guidewire operation.

[0033] The medical-grade silicone anti-slip protrusions on the hand rest enhance operational stability, while the guide groove limit block and buffer pad prevent excessive sliding of the push-pull plate. The enclosed placement space of the platform prevents the guide wire from falling and contaminating the device, and the locking nut prevents the lifting structure from loosening. The medical-grade material meets disinfection requirements, balancing safety and durability. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example 1

[0042] This utility model provides a guidewire operation platform with extension, such as Figures 1-4 As shown, it includes a support plate 1, an operating platform 2 is provided on the top of one side of the support plate 1, the operating platform 2 is adjusted for lifting and lowering operation by lifting adjustment component 5, an extension platform 3 is connected to one side of the operating platform 2, the extension platform 3 covers the upper part of the patient's body, the operating platform 2 is located on one side of the patient's body, a push-pull plate 4 is slidably connected to one end of the operating platform 2, and a hand support plate 41 is installed on the top of one end of the push-pull plate 4.

[0043] Using support plate 1 as the basic positioning component, the platform is quickly fixed by "inserting support plate 1 under the operating mattress"; the lifting and adjusting component 5 moves the operating platform 2 vertically to adjust the height; the extension platform 3 connects with the operating platform 2 to form an extension structure, covering the upper part of the patient's body to increase the placement area; the push-pull plate 4 slides along the operating platform 2, adjusting the hand support plate 41 to a comfortable position for the doctor's hands. No bolts are required for fixing, solving the problem of cumbersome disassembly and assembly of traditional equipment; the lifting and adjusting component 5 adapts to doctors of different heights and surgical positions; the extension platform 3 avoids reliance on mobile carts for instruments, saving space; the hand support plate 41 provides hand support for the doctor, reducing fatigue during prolonged operation.

[0044] In this embodiment, the expansion platform 3 includes a first movable plate 31 and a second movable plate 32. One side of the first movable plate 31 is hinged to the second movable plate 32, and the other side of the first movable plate 31 is hinged to the operating platform 2.

[0045] The expansion platform 3 adopts a hinged structure of "first movable plate 31 + second movable plate 32". The first movable plate 31 and the second movable plate 32 can rotate around the hinge point. When unfolded, the two plates are flat, increasing the instrument placement area; when folded, the two plates fit together, reducing the platform volume. Furthermore, the other side of the first movable plate 31 is hinged to the operating platform 2, ensuring a stable connection between the expansion platform 3 and the operating platform 2. This allows for "on-demand expansion" of the operating space. During surgery, the first movable plate 31 and the second movable plate 32 are unfolded to place guidewires / catheters, and they are folded for storage, reducing storage space. The hinged structure is flexible and durable, avoiding the problem of "insufficient or wasted space" on the fixed-area operating platform 2.

[0046] Specifically, the operating platform 2 has an L-shaped structure. A first guide groove 21 is installed on the bottom of one side of the operating platform 2, and a support base 22 is installed on the inner wall of the other side of the operating platform 2. A second guide groove 23 is installed on the support base 22. A first guide bar 42 is installed on the top of one side of the push-pull plate 4. The first guide bar 42 slides in cooperation with the first guide groove 21. A second guide bar 43 is installed on the bottom of the other side of the push-pull plate 4. The second guide bar 43 slides in cooperation with the second guide groove 23.

[0047] The L-shaped structure of the operating platform 2 is adapted to the spatial layout of "patient's side + upper body". The first guide groove 21 at the bottom of one side of the operating platform 2 and the first guide strip 42 at the top of one side of the push-pull plate 4, and the second guide groove 23 on the inner wall support 22 of the other side of the operating platform 2 and the second guide strip 43 at the bottom of the other side of the push-pull plate 4, form a "double guide sliding cooperation", which restricts the push-pull plate 4 to move only in the horizontal direction and avoids deviation. The L-shaped structure of the operating platform 2 makes reasonable use of the surgical space and does not obstruct the surgical field of vision. The double guide sliding of the first guide groove 21 and the first guide strip 42, and the second guide groove 23 and the second guide strip 43 ensures that the push-pull plate 4 extends and retracts smoothly without jamming, prevents the platform from shaking during operation and affecting the stability of instrument placement, and improves the ease of use.

[0048] Furthermore, the lifting adjustment component 5 includes a fixed sleeve 51, a lifting rod 52 is slidably disposed on the top of the fixed sleeve 51, the top side of the lifting rod 52 is fixedly connected to the operating platform 2, and the bottom end of the fixed sleeve 51 is fixedly connected to the support plate 1.

[0049] The fixing sleeve 51 of the lifting adjustment component 5 is fixed to the support plate 1. The lifting rod 52 can slide along the inner wall of the fixing sleeve 51. By "changing the extension length by sliding the lifting rod 52", the operating platform 2 is raised and lowered. The top side of the lifting rod 52 is fixedly connected to the operating platform 2, forming a basic structure for height adjustment. This provides stable lifting support for the operating platform 2, replacing the traditional "simple adjustment mechanism". The cooperation between the fixing sleeve 51 and the lifting rod 52 ensures a smooth height adjustment process, meeting the operating height needs of doctors of different heights.

[0050] Furthermore, a locking bolt 53 is threaded on one side of the fixing sleeve 51. One end of the locking bolt 53 abuts against the outer wall of the lifting rod 52, and a handle 531 is installed on the other end of the locking bolt 53.

[0051] The locking bolt 53 is threaded into the fixing sleeve 51. When tightened, one end of the locking bolt 53 presses against the outer wall of the lifting rod 52, locking the position of the lifting rod 52 through friction. The handle 531 at the other end of the locking bolt 53 increases the bolt's gripping area, making it convenient for doctors to manually and quickly tighten it. This achieves "instant locking" of the lifting height, preventing the operating platform 2 from automatically rising and falling via the lifting rod 52 due to vibration during surgery. The handle 531 design eliminates the need for tools, improves adjustment efficiency, and solves the problem of "cumbersome operation" in traditional locking structures.

[0052] Furthermore, a locking nut 532 is installed on the locking bolt 53.

[0053] The locking nut 532 and the locking bolt 53 are threaded together. After tightening, the locking nut 532 fits against the outer wall of the fixing sleeve 51. The "double thread locking of the locking bolt 53 and the locking nut 532" prevents the locking bolt 53 from loosening due to surgical vibrations, thus enhancing locking stability. This prevents the lifting rod 52 from shifting due to loosening of the locking bolt 53 during surgery, which could lead to changes in the height of the operating platform 2. This eliminates the operational risks caused by unexpected height changes and improves the safety of equipment use.

[0054] Furthermore, the top of the hand support plate 41 has an inwardly concave arc surface structure.

[0055] The hand support plate 41 at one end of the push-pull plate 4 adopts an inwardly concave arc surface structure. This arc surface conforms to the natural curvature of the human wrist, so that the wrist is evenly stressed when placed on the hand support plate 41, which is in line with ergonomic design. It reduces local pressure between the wrist and the hand support plate 41, avoiding wrist strain caused by prolonged operation; the arc surface structure of the hand support plate 41 improves hand placement comfort, indirectly ensuring the accuracy of guide wire operation and solving the problem of "poor fit" of traditional hand supports.

[0056] Furthermore, both ends of the first guide groove 21 are provided with limiting blocks, which are integrally formed with the operating platform 2, and the inner side of the limiting blocks is provided with buffer pads to limit the sliding stroke of the push-pull plate 4.

[0057] Limiting blocks are provided at both ends of the first guide groove 21 on one side of the operating platform 2. The limiting blocks are integrally formed with the operating platform 2 and limit the sliding stroke of the push-pull plate 4 by physical blocking, preventing the push-pull plate 4 from sliding out of the first guide groove 21. In addition, a buffer pad is provided on the inner side of the limiting block, which absorbs the impact force when the push-pull plate 4 slides to the end through elastic deformation, reducing the impact. This prevents the push-pull plate 4 from falling out of the first guide groove 21 of the operating platform 2 due to excessive sliding, protecting the structure of the push-pull plate 4 and the operating platform 2. The buffer pad avoids noise and component wear caused by collisions, extending the service life of the push-pull plate 4 and the operating platform 2.

[0058] Furthermore, the outer wall of the lifting rod 52 is provided with a scale line 521 along the length direction, and the top outer side of the fixed sleeve 51 is provided with a pointer 511, which corresponds to the scale line 521 to indicate the lifting height of the operating platform 2.

[0059] The lifting adjustment component 5 has a scale line 521 on the outer wall of the lifting rod 52 along its length. A pointer 511 is located on the top outer side of the fixing sleeve 51, corresponding to the scale line 521. By aligning the pointer 511 with the specific value on the scale line 521, the actual lifting height of the operating platform 2 is displayed intuitively. This achieves "visualized and precise control" of the operating platform 2's height adjustment, avoiding the errors of traditional adjustments based on "experience-based estimation." Different doctors can quickly adapt to the same height by aligning the pointer 511 with the scale line 521, improving operational consistency.

[0060] Furthermore, the top of the curved surface of the hand support plate 41 is provided with several anti-slip protrusions, which are made of medical-grade silicone and are evenly distributed in an array.

[0061] The top of the curved surface of the hand support plate 41 is provided with several anti-slip protrusions. These protrusions are made of medical-grade silicone and are evenly distributed in an array. The medical-grade silicone material increases the friction between the wrist and the hand support plate 41, preventing the hand from slipping. It is also biocompatible and resistant to disinfection. This prevents the surgeon's hand from slipping on the hand support plate 41 due to sweat or equipment vibration during surgery, ensuring the stability of guidewire operation. The anti-slip protrusions made of medical-grade silicone material meet the disinfection requirements of the operating room, preventing cross-infection, and improving the comfort of contact between the hand and the hand support plate 41.

[0062] When using the guidewire operating platform with extension of this utility model, the entire platform is first disinfected with medical grade to ensure that it meets the hygiene requirements of the operating room. According to the surgical position, such as the patient lying supine and the doctor's operating position, the support plate 1 is inserted horizontally under the operating mattress. The front and back positions of the support plate 1 are adjusted so that the operating platform 2 is aligned with the doctor's preset operating area. The pressure of the mattress is used to achieve stable fixation of the platform without the need for bolt installation.

[0063] Height Adjustment: Based on their height or surgical field requirements, the doctor loosens the locking bolt 53, pushes the operating platform 2 to slide the lifting rod 52 along the fixed sleeve 51, observes the pointer 511 aligning with the scale line 521 of the lifting rod 52, and after determining the appropriate height, tightens the locking bolt 53, then tightens the lock nut 532 to prevent loosening, thus locking the operating platform 2 at its height. Space Expansion: If multiple guidewires, catheters, or related instruments need to be placed, the second movable plate 32 of the expansion platform 3 is rotated around the hinge point of the first movable plate 31 to unfold, and then the first movable plate 31 is rotated around the hinge point with the operating platform 2 to a horizontal position, so that the expansion platform 3 covers the upper part of the patient's body and is aligned with the operating platform. Platform 2 together forms a large instrument placement area, avoiding reliance on mobile trolleys for instruments; Hand support adjustment: According to the hand operation distance, the doctor pushes the push-pull plate 4, which slides horizontally along the first guide groove 21 via the first guide bar 42 and along the second guide groove 23 via the second guide bar 43, adjusting the hand support plate 41 to a comfortable wrist position. During operation, the wrist is placed on the concave arc surface of the hand support plate 41, and the silicone anti-slip protrusions prevent the hand from slipping and reduce fatigue from holding the guidewire for a long time; Instrument placement: Guidewires, catheters and other instruments are classified and placed on the operating platform 2 and the expansion platform 3 to avoid instruments falling and contaminating. No body movement is required when picking up and placing them, shortening the operation path and improving surgical efficiency.
