Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a guidewire and catheter fixation device. Background Technology

[0002] With the continuous development of medical technology, interventional surgery is increasingly widely used in cardiovascular and cerebrovascular diseases, tumors, and non-vascular diseases due to its advantages such as minimally invasiveness and precision. Guidewires and catheters are indispensable instruments in interventional surgery, playing crucial roles in the procedure. Guidewires guide surgical instruments to the lesion site, while catheters establish delivery channels to deliver drugs or instruments into the body.

[0003] Currently, during a single surgical procedure, multiple guidewires and / or catheters may be inserted into the patient simultaneously. Each guidewire or catheter serves a specific purpose, resulting in a complex array of guidewires and catheters extending from inside the patient's body to the outside of the operating table. However, in actual surgery, guidewires and catheters that have been or are planned to be inserted into the patient are not currently secured on the operating table. They may slide or wobble, causing positional changes, or even fall off the table. In some interventional procedures that last for tens of hours, prolonged movement of guidewires and catheters may cause them to slip out of their intended positions within the patient's body, prolonging the procedure or leading to surgical failure. Utility Model Content

[0004] Therefore, it is necessary to provide a guidewire and catheter fixation device to address the above problems, for fixing the guidewire and catheter and preventing unexpected movement of the guidewire and catheter during surgery. The fixation device includes: a base having a bottom plate, on which a guidewire fixation area and a catheter fixation area are respectively provided along the length direction; at least two mounting seats are sequentially spaced along the length direction in the guidewire fixation area, and a receiving groove is formed between adjacent mounting seats; the catheter fixation area has a protrusion with one or more opening slots, which are sequentially spaced along the length direction when there are multiple opening slots, and the catheter is fixed in the opening slot;

[0014] Furthermore, it also includes a guide wire fixing pad, which is embedded in the receiving groove; when the guide wire pressure plate rotates into the receiving groove, the guide wire fixing pad is located between the guide wire pressure plate and the base plate.

[0015] Furthermore, it also includes a catheter fixing pad, which has one or more catheter fixing grooves; the protrusion has a receiving cavity, and the lower side of the receiving cavity has a bottom opening that penetrates the base plate, the opening groove communicating with the receiving cavity; the catheter fixing pad is embedded in the receiving cavity, and each catheter fixing groove is aligned with each opening groove so that the catheter fixing groove is exposed in the receiving cavity.

[0036] First Embodiment

[0037] See Figure 1As shown, this embodiment provides a guidewire and catheter fixing device 100, which has a base 10 and a bottom plate 11. A guidewire fixing area S1 and a catheter fixing area S2 are respectively provided on the bottom plate 11 along its length. The guidewire fixing area S1 has at least two mounting seats 14 spaced apart along its length, and a receiving groove 15 is formed between adjacent mounting seats 14. The catheter fixing area S2 has a protrusion 12, and one or more opening grooves 13 are spaced apart along its length. The catheter 60 is fixed in the opening groove 13. A guidewire pressure plate 30 is rotatably connected to the mounting seats 14 and can rotate in a direction away from or towards the receiving groove 15. When the guidewire pressure plate 30 rotates into the receiving groove 15, it compresses the guidewire 50 located between the bottom plate 11 and the guidewire pressure plate 30 to fix it. For example, see [link to example]. Figure 1 As shown, there are four mounting bases 14 spaced apart along the length direction, and four opening slots 13 are also provided along the length direction. There is no limit to the specific number of mounting bases 14 and opening slots 13.

[0038] See Figures 2-4 The specific structure of the base 10 is described below. The base 10 includes a base plate 11, which is a plate-like structure extending along the length direction and is used to support or accommodate other components. A guidewire fixation area S1 and a catheter fixation area S2 are sequentially arranged along the length direction on the upper surface of the base plate 11. Fixing protrusions 17 are provided at both ends of the base plate 11, and fixing holes 18 are provided on the fixing protrusions 17. During the operation, the fixing hole 18 at either end can be fixed to the operating table using surgical hemostatic forceps or sutures to prevent the fixation device 100 from moving as a whole and thus causing the guidewire 50 and catheter 60 to move.

[0039] For the guide wire fixing area S1, the base plate 11 is provided with a plurality of mounting seats 14 arranged sequentially at intervals along the length direction, and a receiving groove 15 is formed between two adjacent mounting seats. Each mounting seat 14 includes a middle connecting part 142 fixedly connected to the base plate 11 and a side plate 141. The front and rear sides of the middle connecting part 142 are respectively fixedly provided with side plates 141. The middle connecting part 142 is a plate-shaped structure, vertically arranged on the base plate 11 and perpendicular to the length direction of the base plate 11. The side plates 141 are respectively arranged at both ends of the middle connecting part 142 and perpendicular to the middle connecting part 142, so that the entire mounting seat 14 forms an I-shaped structure. A pivot mounting groove 144 is provided at the top of each side plate 141 for rotatably connecting with the guide wire pressure plate 30, and a snap-fit ​​groove 143 is provided on the middle connecting part 142 for snap-fitting with the guide wire pressure plate 30. In addition, a first mark 19a is also provided at the guide wire fixing area S1 position of the base plate 11. In this embodiment, the first mark 19a includes a guidewire indicator mark and a first numerical mark. The guidewire indicator mark is used to remind the operator that the guidewire is to be fixed here, while the first numerical mark includes multiple numerical numbers, each number being marked on the corresponding receiving slot 15. For example, when there are three receiving slots, a numerical number is marked next to each receiving slot in sequence, such as "1", "2", and "3". For each numerical number, it is used to mark the guidewire at the corresponding position. For example, "1" represents that the guidewire here is guidewire number 1, which facilitates quick identification and judgment by the doctor. For example, when there are three guidewires in the patient's body, the doctor can record the specific location, function, and type of operation of each guidewire at each numerical number, so that the specific guidewire can be quickly and accurately identified in subsequent surgical procedures, reducing the time spent on trial or identification of guidewires and avoiding misoperation of the guidewire, such as withdrawing a temporarily useful guidewire from the body.

[0040] For the catheter fixing area S2, a protrusion 12 is provided on the base plate 11. The protrusion 12 is a block-shaped shell structure with a receiving groove 16 extending vertically from the base plate 11. The receiving groove 16 extends downward to the bottom of the base plate 11, so that the lower side of the receiving groove 16 has a bottom opening penetrating the base plate 11. At least one opening groove 13 is provided on the protrusion 12. When there are multiple opening grooves 13, the multiple opening grooves 13 are arranged sequentially at intervals along the length direction on the protrusion 12, and each opening groove 13 extends downward from the top of the protrusion 12 to a certain distance. In one embodiment, the opening groove 13 can be formed by cutting the protrusion 12 vertically from top to bottom, and the opening groove 13 communicates with the receiving groove 16, so that the receiving groove 16 forms a cavity structure with a bottom opening at the lower end and communicating with the outside at the upper end. The cross-sectional shape of the opening groove 13 is a Y-shaped structure to facilitate the catheter 60 entering from the entrance of the opening groove 13. In addition, a plurality of connecting columns 121 are arranged at intervals on the top wall of the receiving groove 16.

[0041] In addition, a second mark 19b is provided at the catheter fixation area S2 position of the base plate 11. Similar to the first mark 19a, the second mark 19b includes a catheter indicator mark and a second numerical mark. The catheter indicator mark is used to remind the operator that this is the location for catheter fixation, while the second numerical mark also includes multiple numerical numbers, each number being marked near each receiving slot 15, such as "1", "2", and "3" as shown in the figure. Similar to the first numerical mark, the second numerical mark is used to mark specific catheters, making it easier for doctors to quickly identify and judge specific catheters, shortening operation time and reducing catheter mishandling.

[0042] See Figure 5 As shown, the snap-fit ​​groove 143 is a groove structure extending along the length direction, which may or may not penetrate the intermediate connecting portion 142. In this embodiment, a wedge-shaped surface 1431 is provided on the upper edge of the snap-fit ​​groove 143. One end of the wedge-shaped surface 1431 extends to the top of the intermediate connecting portion 142, and the other end extends to the inner wall of the snap-fit ​​groove 143.

[0043] See Figures 6-7 The fixing device 100 will be further described below. The fixing device 100 in this embodiment includes a wire fixing pad 20, which is a block structure with fixing pad protrusions 21 on its left and right sides. A fixing pad groove 22 is formed between the two fixing pad protrusions 21, resulting in a U-shaped cross-section of the wire fixing pad 20 along its length. The shape and size of the wire fixing pad 20 match the receiving groove 15, allowing the wire fixing pad 20 to be embedded into the receiving groove 15 from top to bottom.

[0044] In addition, the fixing device 100 also includes a catheter fixing pad 40, which is a block structure whose shape and size match the receiving cavity 16, allowing the catheter fixing pad 40 to enter and be embedded in the receiving cavity 16 through the bottom opening. The catheter fixing pad 40 has one or more catheter fixing grooves 41 along its length. When there are multiple catheter fixing grooves 41 and multiple opening grooves 13, each catheter fixing groove 41 corresponds to each opening groove 13, and their shapes, sizes, and positions are matched. Therefore, when the catheter fixing pad 40 is embedded in the receiving cavity 16, each catheter fixing groove 41 is aligned with each opening groove 13, so that all catheter fixing grooves 41 are exposed in the receiving cavity 16 through the opening grooves 13. In this embodiment, both the guidewire fixing pad 20 and the catheter fixing pad 40 are made of elastic material, such as silicone or rubber. In order to achieve a fixed connection between the catheter fixing pad 40 and the protrusion 12, a plurality of fixing pad connection holes 42 are provided on the top of the catheter fixing pad 40. Each fixing pad connection hole 42 corresponds to and matches each connecting post 121, so that each connecting post 121 is connected to each fixing pad connection hole 42 and the catheter fixing pad 40 is fixedly placed in the receiving groove 40.

[0045] See Figure 8 The structure of the guide wire pressure plate 30 is described below. The guide wire pressure plate 30 includes a pressing plate 31, a first connecting part 32 is provided on the left side of the pressing plate 31, and a second connecting part 33 is provided on the right side of the pressing plate 31. The pressing plate 31, the first connecting part 32 and the second connecting part 33 form a U-shaped plate structure, which can be rotated into the receiving groove 15.

[0046] A rotating shaft 34 is provided on the first connecting part 32. The rotating shaft 34 extends into the rotating shaft mounting groove 144 to form a rotating pair, thereby realizing the rotatable connection between the first connecting part 32 and the mounting base 14. A clearance groove 35 is provided on the first connecting part 32, extending to the end of the first connecting part 32. In this embodiment, there are two rotating shafts 34, which are respectively provided on the front and rear sides of the clearance groove 35, and each rotating shaft 34 is rotatably connected to its corresponding rotating shaft mounting groove 144.

[0047] The second connecting portion 33 has a locking portion 36 at its end. The locking portion 36 includes a locking plate 361, the upper end of which is fixedly connected to the second connecting portion 33, and the lower end of which has a locking protrusion 362. Additionally, a handle portion 37 is fixedly provided on the upper side of the second connecting portion. The handle portion 37 is integrally formed with the locking portion 36 or separately fixedly connected to the second connecting portion 33. In this embodiment, the surface of the handle portion 37 has multiple anti-slip protrusions to facilitate operator operation.

[0048] Referring to Figures 9-10, the snap-fit ​​process of the wire guide plate 30 is explained. When the wire guide plate 30 rotates towards the base plate 11 (clockwise), it gradually rotates into the receiving groove 15. During the rotation, the snap-fit ​​protrusion 362 is guided by the wedge-shaped surface 1431 and gradually slides into the snap-fit ​​groove 143, thereby achieving the snap-fit ​​between the snap-fit ​​part 36 and the snap-fit ​​groove 143. At this time, the wire guide plate 30 is in a snap-fit ​​state relative to the mounting base 14, and the two remain relatively fixed.

[0049] See also Figure 1 As shown, when one wire guide plate 30 rotates in a direction away from the base plate 11 (counterclockwise), because the first connecting portion 32 of the wire guide plate 30 is provided with a relief groove 35, at least a portion of the handle portion of the adjacent wire guide plate (the other wire guide plate located on the left) will be embedded in the relief groove 35 during rotation. This prevents interference between the handle portion of the wire guide plate and its adjacent wire guide plate during rotation, thus preventing it from rotating smoothly. Therefore, providing the relief groove 35 ensures that the wire guide plate 30 rotates smoothly in a direction away from the base plate 11.

[0050] See Figures 11-13 The following describes the usage process of the guidewire and catheter fixation device in this embodiment. See also... Figure 11 As shown, when it is necessary to fix the guidewire 50, first place the guidewire 50 on the guidewire fixing pad 20. See also Figure 12 As shown, rotating the guide wire pressure plate 30 clockwise causes it to rotate into the receiving groove 15. Once the guide wire pressure plate 30 is in position, it engages with the mounting base 14, thus placing the guide wire pressure plate 30 in a locked state. When the guide wire pressure plate 30 is locked, the bottom surface of the pressing plate 31 of the guide wire pressure plate 30 and the top surface of the guide wire fixing pad 20 have a certain gap, which is smaller than the diameter of the guide wire 50, thereby achieving compression and fixing of the guide wire 50. Since the guide wire fixing pad 20 is an elastic element, when the guide wire 50 is compressed, the elastic restoring force of the guide wire fixing pad 20 will clamp the guide wire 50 between the guide wire fixing pad 20 and the guide wire pressure plate 30. Referring to Figure 13, when it is necessary to fix the catheter 60, the catheter 60 is slid through the opening groove 13 to the bottom of the catheter fixing groove 41 of the catheter fixing pad 40. Since the bottom width of the conduit fixing groove 41 is smaller than the outer diameter of the conduit 60, and the conduit fixing pad 40 is an elastic element, the conduit fixing pad 40 will squeeze the conduit 60 embedded in the conduit fixing groove 41, thereby fixing the conduit 60.

[0051] Therefore, the guidewire and catheter fixing device 100 of this embodiment can fix multiple guidewires and catheters in an orderly manner at the same time, preventing multiple guidewires and catheters from being randomly distributed on the operating table and causing confusion among the devices; in addition, since the guidewires and catheters are fixed, they will not move unexpectedly during the operation; finally, since the first mark 19a and the second mark 19b are respectively provided on the base plate 11, it is convenient for doctors to memorize specific guidewires and catheters, quickly identify specific guidewires and catheters, shorten operation time, and reduce the probability of misoperation.

[0052] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. The protection scope of this utility model patent should be determined by the appended claims.
