Description

Technical Field

[0001] The present invention relates to the technical field of minimally invasive vascular interventional surgery, and more particularly to a universal adaptive catheter bed connection base. Background Art

[0002] Minimally invasive cardiovascular interventional therapy is a primary treatment for cardiovascular and cerebrovascular diseases. Compared to traditional surgical procedures, it offers significant advantages, including smaller incisions and shorter postoperative recovery times. Cardiovascular interventional surgery involves the doctor manually inserting devices such as catheters, guidewires, and stents into the patient's body to complete the treatment. Interventional procedures require the use of a catheter bed.

[0003] During interventional surgery, some auxiliary surgical equipment, such as interventional surgical robots and contrast agent injection devices, are required. These devices are usually mounted on the guide rails on the side of the catheter bed. However, there are several problems with fixing the equipment on the catheter bed during interventional surgery:

[0004] (1) There are many existing DSA manufacturers, and the length, width, and height of the side rails of the catheter beds of each manufacturer are not uniform, and the height of the bed panels is also different. This results in large differences in the installation of the equipment on different catheter beds, making it impossible to effectively fix it, posing a safety hazard; the connection base is not very versatile and can often only adapt to a single device;

[0005] (2) Most existing connection bases are designed with slot-type fixings, which are difficult to install and remove, are time-consuming, and affect surgical efficiency;

[0006] (3) The fixing device for connecting the base is generally manual, and the fixing process often requires the cooperation of multiple people, which is laborious and requires more human resources.

[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0057] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0059] Because existing connection bases cannot meet the installation requirements of catheter bed rails of different sizes, it is impossible to achieve universality of the connection base. In view of this, the embodiment of the present invention discloses a universal adaptive catheter bed connection base, which is used to connect the guide rails 301 on the side of the catheter bed 300, and its top supports the surgical auxiliary equipment 400; see the attached Figure 1-4 , comprising: a lifting and pressing plate assembly 100 and a clamping device 200;

[0060] The lifting and pressing plate assembly 100 includes: a bottom plate 105, wherein the bottom plate 105 includes a horizontal section, one end of the horizontal section protrudes upward to form an upper vertical section, and the other end of the horizontal section protrudes downward to form a lower vertical section, wherein the lower vertical section is a first clamping portion 1051; a pressing plate 101, wherein the pressing plate 101 has a plate body placed on top of the catheter bed 300, one end of the plate body protrudes downward to form a sliding plate 1011, wherein the sliding plate 1011 is slidably connected to the upper vertical section of the bottom plate 105, and the plate body is located above the horizontal section of the bottom plate 105;

[0061] The clamping device 200 has second clamping parts 203 and 207 that cooperate with the first clamping part 1051 to clamp, and an adjustable guide rail clamping area is formed between the first clamping part 1051 and the second clamping parts 203 and 207;

[0062] Advantageously, the bottom plate 105 is provided with the locking portion for fixing the sliding plate 1011 .

[0063] By using the lower vertical section of the base plate as the fixed first clamping part 1051, and forming an adjustable guide rail clamping area through the second clamping parts 203, 207 and the first clamping part 1051, it is possible to meet the connection needs of guide rails of different sizes. After fixation, the base plate 105 and the sliding plate 1011 are locked by the locking part.

[0064] See attached Figure 5-8 Two groups of first linear guide rails 107 are fixed on the outer wall of the upper vertical section of the base plate 105, and a first slider slides on each group of the first linear guide rails 107, and the outer wall of the first slider is fixed with the sliding plate 1011; thereby, a sliding connection is realized between the sliding plate 1011 and the upper vertical section of the base plate 105.

[0065] In the above structure, the pressure plate can be made of aluminum alloy, and the pressure plate is installed on the first linear guide rail and can move up and down.

[0066] More advantageously, two support seats 1052 extend outward from the bottom of the base plate 105 near the upper vertical section. A tension spring 106 is vertically connected to each support seat 1052, and the top of each tension spring 106 is connected to the bottom of a corresponding first slider. That is, the tension spring 106 is vertically arranged, with its top connected to the bottom of the first slider. A positioning hole can be provided in the bottom of the first slider, and the top of the tension spring is fixed in the positioning hole. The bottom of the tension spring is fixed to the support seat, and a mounting seat for the tension spring can be provided on the support seat. As a result, when the sliding plate 1011 slides vertically, the spring acts as a buffer and can also cause the sliding plate to automatically return to its original position.

[0067] Advantageously, a soft silicone pad is installed at the contact position between the plate and the top of the guide rail 301 to prevent damage to the catheter bed.

[0068] In the embodiments of the invention, see the attached Figure 5 The top of the base plate 105 is connected upwardly with a platform 1053 , on which a plurality of fixing holes can be provided for supporting the surgical auxiliary equipment 400 , and an installation space K is formed between the platform 1053 and the base plate 105 .

[0069] The bottom plate of the present invention is provided with weight-reducing grooves, which are beneficial to weight reduction. The lower vertical section of the bottom plate can be separated, corresponding to the number of the second clamping parts, and weight-reducing grooves are also formed between adjacent first clamping parts 1051 after separation.

[0070] In the embodiments of the present invention, see the attached Figure 5-8 , the locking portion is installed in the installation space K, including:

[0071] A second linear guide rail 104 is arranged perpendicular to the upper vertical section of the base plate 105 and is fixed to the bottom wall of the installation space K. A notch 1054 is formed on the upper vertical section of the base plate 105. A second slider slides on the top of the second linear guide rail 104.

[0072] A locking block 103 is fixed on the top of the second sliding block, and the locking block 103 is lockably connected to the inner wall of the sliding plate 1011;

[0073] The push-pull electromagnet 102 , the locking block 103 is connected to the push rod of the push-pull electromagnet 102 , and the push-pull electromagnet 102 is fixed on the bottom wall of the installation space K; the push-pull electromagnet 102 is connected to the electric control system.

[0074] Thus, by powering or de-energizing the push-pull electromagnet through the electronic control system, the locking block 103 and the inner wall of the sliding plate 1011 can be locked or separated. The electronic control system mentioned in the present invention is a prior art system that can include a housing, a power supply, a control chip, a display, connecting wires, etc., which serves to assist in achieving automatic control.

[0075] Advantageously, the sliding plate 1011 has a protruding block in the middle, the block has a first tooth-shaped structure, and the locking block 103 has a second tooth-shaped structure that cooperates with the first tooth-shaped structure. In order to ensure the convenience of locking and separation, the first tooth-shaped structure and the second tooth-shaped structure can both adopt straight teeth.

[0076] The pressure plate is initially positioned at the bottom due to the tension spring. When the surgeon places the connecting base on the side rails of the catheter bed, the front end of the pressure plate rests on the bed panel, allowing the plate to move upwards freely. Once the surgeon has placed the pressure plate, its height is equal to the height of the bed panel and the side rails. The push-pull electromagnet is then activated, locking the current position through the teeth of the locking block and sliding plate, preventing the pressure plate from moving and securing it to the bed panel. After the surgery, to remove the connecting base, the push rod of the push-pull electromagnet is retracted. This removes the locking block and sliding plate, allowing the pressure plate to move freely. Once the connecting base leaves the bed, the pressure plate returns to its initial position due to the tension spring.

[0077] See attached Figure 9 and 10 In the embodiment of the present invention, the clamping device 200 includes:

[0078] Two third linear guide rails 209 are fixed parallel to the ends of the horizontal section of the base plate 105 and parallel to the second linear guide rail 104; a third slider slides on each of the third linear guide rails 209;

[0079] A connecting plate 202, 208 is fixed on each of the third sliders, the bottom of the connecting plate 202, 208 is bent to form a vertical connecting section, the second clamping part 203, 207 is fixed on the inner side of the connecting section and is arranged opposite to the first clamping part 1051;

[0080] A lead screw motor and bracket 211, 213 is fixed on the horizontal section of the bottom plate 105 and is located between the two third linear guides 209, the lead screw of the lead screw motor and bracket 211, 213 is matched with the corresponding threaded hole of the connecting plate 202, 208;

[0081] A switch 210 is mounted on the horizontal section of the bottom plate 105 from the bottom, the top of the switch 210 is sleeved with a switch spring 205, and the switch 210 and the switch spring 205 move in the space formed by the switch connecting plate 212 and the bottom plate 105;

[0082] The switch 210 and the lead screw motor are connected with the electric control system.

[0083] In a specific embodiment, the second clamping part 203, 207 is made of hard silica gel, and the section close to the first clamping part 1051 is a long inclined plane which directly contacts with the guide rail 301.

[0084] More advantageously, a pressure sensor 206 is connected to the outer side of each of the connecting sections, the pressure sensor 206 is connected with the electric control system, and the second clamping part 203, 207 is fixed on the pressure sensor 206.

[0085] Referring to the accompanying drawings Figure 11 and 12After the doctor places the connecting base on the guide rail on the side of the catheter bed, the guide rail will press the switch under the connecting base. After pressing, the two sets of second clamping parts, driven by the two sets of screw motors, will perform a synchronous clamping action until the pressure sensor detects a certain pressure value and stops. The second clamping part adopts a long bevel design and is processed with harder silicone to ensure that it can adapt to the width of the side guide rails of catheter beds of different sizes. The pressure sensor allows the system to obtain the clamping force of the guide rail at any time. If an abnormality is detected, the doctor can be notified in time by using a warning light or a buzzer, which can effectively ensure the safety of the operation. Among them, when the pressure plate 101 is placed on the catheter bed 300, it will automatically rise under the action of the catheter bed 300. When the lower surface of the base plate 105 touches the upper surface of the side guide rail of the catheter bed, the pressure plate 101 will stop moving. At this time, the electronic control system controls the push-pull electromagnet 102 to push the locking block 103 to move until the tooth profile of the locking block 103 and the pressure plate 101 are completely aligned. At this time, the pressure plate 101 will not move. When the operation is completed, the push-pull electromagnet 102 retracts the locking block 103, and the pressure plate 101 can move freely.

[0086] The switch 210 is installed in the square hole opened in the horizontal section of the bottom plate 105. The switch spring 205 is placed in the circular column on the upper surface of the switch. Under the action of the switch spring 205, if the connecting base is not placed on the guide rail, the switch will pop up. The switch connecting plate 212 is installed on the bottom plate 105 to cooperate with the switch 210. When the connecting base is not placed on the guide rail, Figure 13 As shown, the lower end of the switch 210 will have an outward protrusion on the lower surface of the base. Figure 14 As shown, the switch 210 is pressed, so that the electronic control system will receive the message and execute the next action. When the switch 210 is not pressed, under the action of the screw motor, the second clamping parts 203 and 207 will move away from the guide rail on the side of the catheter bed, as shown in FIG. Figure 15 As shown, this will make it easier for doctors to place the connection base on the guide rail on the side of the catheter bed. When the switch 210 is pressed, the second clamping parts 203 and 207 will move closer to the guide rail on the side of the catheter bed under the action of the screw motor. The clamping force can be sensed by the pressure sensors 204 and 206, and the guide rail will be pressed until the clamping force reaches a certain value and stops. Figure 16 As shown, once clamped the connection base will not move.

[0087] The overall operation process involves placing the connecting base on the side rails of the catheter bed and placing the pressure plate on the bed panel. The clamping device then automatically clamps the pressure plate and the bed rails. The entire process takes approximately 5 seconds. After ensuring a secure installation, the surgeon places the necessary surgical aids on the platform and proceeds with the procedure. After removing the surgical aids, the connecting base is removed. The surgeon flips a switch to activate the clamping device, waits for the clamping device to complete, and then lifts the device from the bottom to complete the removal.

[0088] The present invention is used on the guide rail on the side of the catheter bed, and adopts a top-down pressing installation method. After it is placed, the system will automatically complete the fixing action of each part. The whole process is very fast and can be completed in about 5 seconds. After use, it can be easily dismantled. After the device is loosened and fixed, the connecting base can be removed from the catheter bed from the bottom up. The entire installation and removal process is very fast, and the doctor does not need to perform more complicated operations. The device is small in size, light in weight, convenient and practical. It solves the problems of large size differences among catheter beds of various manufacturers in existing interventional surgeries, no universal installation structure, complicated installation and removal processes, time-consuming and labor-intensive, loose fixation, low universality of the connecting base, and reduced surgical efficiency.
