Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a cardiovascular interventional guidewire shaping device. Background Technology

[0002] In cardiovascular interventional procedures, guidewire shaping is one of the key steps to a successful procedure. The guidewire needs to be pre-shaped to a specific bending angle (such as J-shape, acute angle, or arc) based on the patient's vascular anatomy (e.g., degree of tortuosity, bifurcation angle, or lesion location) to ensure it can smoothly pass through complex vascular pathways and accurately reach the target location. Currently, guidewire shaping in clinical practice mainly relies on manual operation by the surgeon, i.e., the operator directly bends the guidewire tip with their fingers.

[0003] The following are some common problems encountered by novice doctors regarding guidewire shaping:

[0004] 1. Manual shaping requires doctors to estimate the bending angle and the intensity of force based on their experience. Novice doctors often cause shaping deviations due to uneven force, which requires repeated adjustments and prolongs the preoperative preparation time.

[0005] 2. The tiny guidewire is difficult to fix during manual shaping and is prone to displacement, which can lead to deviation in the bending position or even shaping failure.

[0006] 3. Repeated bending may damage the outer coating or internal structure of the guidewire, increasing the risk of guidewire breakage or thrombosis.

[0007] Therefore, it is necessary to develop a new cardiovascular interventional guidewire shaping device to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a cardiovascular interventional guidewire shaping device to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a cardiovascular interventional guidewire shaping device, comprising a support plate, and further comprising: an auxiliary part, which includes a support base and a guidewire hole, the guidewire hole being opened in the middle of the support base; a rectangular hole, which is opened at one end of the support base; a fixing post, one end of which is slidably disposed in the rectangular hole; an auxiliary rod, the middle of the outer side wall of which is connected to the other end of the fixing post; and a pressing part, which is disposed on the top of the support plate and located at one end of the support base; through the cooperation of the pressing part and the auxiliary part, the pressing part fixes the guidewire to the upper surface of the support plate, and then the auxiliary part shapes the guidewire.

[0010] Preferably, a tapered hole is formed at the end of the support base away from the auxiliary rod and communicates with the guide wire hole.

[0011] Preferably, the auxiliary hole is formed on the upper surface of the support plate and communicates with the tapered hole.

[0012] Preferably, the pressing part includes: a sliding groove having multiple openings and disposed at one end of the support plate away from the support base; a push plate disposed above the support plate; and a sliding column having its lower end slidably disposed in the corresponding sliding groove and its upper end fixedly disposed below the push plate.

[0013] Preferably, the pressing part further includes a return spring, which is sleeved on the outer wall of the corresponding sliding column, the upper end of the return spring being connected to the push plate and the lower end being connected to the support plate.

[0014] Preferably, the pressing part further includes a limiting plate, which is disposed at one end of the support base near the push plate, the limiting plate being used to restrict the push plate to move up and down only between the limiting plate and the support plate.

[0015] Preferably, the pressing part further includes a compression pad, which is disposed below the middle part of the push plate, and the compression pad can fix the guide wire under the action of the push plate.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model reduces the difficulty for novice doctors in shaping by setting up auxiliary rods, fixing posts and guide wire holes, thereby improving the efficiency of novice doctors in shaping. The guide wire is inserted into the guide wire hole through the tapered hole, and a part of it extends out of the guide wire hole for shaping. Then, the extended guide wire is pressed to make it contact the outer wall of the auxiliary rod. Then, the guide wire is shaped according to different pressing angles to achieve the specified shaping shape.

[0018] 2. This utility model prevents the guide wire from shifting during shaping by setting a pressing part, which would affect the shape of the shaping and thus improve the effect of the guide wire in shaping. By pressing the push plate, the push plate moves downward and drives the extrusion pad to fix the guide wire and prevent it from shifting during the shaping process.

[0019] 3. By setting a tapered hole, this utility model facilitates the insertion and shaping of the guide wire into the guide wire hole, thereby improving the efficiency of the guide wire in the perforation process. Attached Figure Description

[0025] 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.

[0026] This utility model provides, for example Figures 1 to 4 The cardiovascular interventional guidewire shaping device shown includes a support plate 1 and an auxiliary part 2, which includes a support base 201 and a guidewire hole 202. The guidewire hole 202 is located in the middle of the support base 201, and the diameter of the guidewire hole 202 is slightly larger than the diameter of the guidewire. A rectangular hole 203 is located at one end of the support base 201. A fixing post 204 is slidably disposed at one end in the rectangular hole 203. The fixing post 204 experiences resistance when sliding in the rectangular hole 203 to prevent it from falling out of the rectangular hole 203 during handling. An auxiliary rod 205 is connected to the other end of the fixing post 204 at the middle of its outer side wall. The auxiliary rod 205, the rectangular hole 203, and the fixing post 204 are located above the guidewire hole 202, and can also be located below the guidewire hole 202 as needed.

[0027] It should be noted that the diameter of the auxiliary rod 205 is not limited. Different diameter auxiliary rods 205 can be selected for use to ensure that the guide wire can achieve the specified bending degree. The auxiliary rod 205 in the figure is cylindrical, but it is not limited to a cylindrical shape. It can also be other shapes such as trapezoidal cross-section, used to achieve the specified bending degree of the guide wire.

[0028] With the cooperation of the pressing part 3 and the auxiliary part 2, the pressing part 3 fixes the guide wire to the upper surface of the support plate 1, and the auxiliary part 2 shapes the guide wire.

[0029] The pressing part 3 is disposed on the top of the support plate 1 and located at one end of the support base 201; multiple sliding grooves 301 are provided and disposed at the end of the support plate 1 away from the support base 201; the pushing plate 302 is disposed above the support plate 1; the sliding column 303 has its lower end slidably disposed in the corresponding sliding groove 301 and its upper end fixedly disposed below the pushing plate 302; the return spring 304 is sleeved on the outer wall of the corresponding sliding column 303, the upper end of the return spring 304 is connected to the pushing plate 302, and its lower end is connected to the support plate 1; the limit Position plate 305 is located at one end of support base 201 near push plate 302. Position plate 305 is used to limit push plate 302 to move up and down only between position plate 305 and support plate 1. Extrusion pad 306 is located below the middle of push plate 302. Extrusion pad 306 can fix guide wire under the action of push plate 302. Extrusion pad 306 is made of rubber material, which can avoid damage to extrusion pad 306 when fixing guide wire, and also avoid guide wire displacement during plasticization, which would affect the shape of guide wire.

[0030] A tapered hole 4 is opened at the end of the support base 201 away from the auxiliary rod 205 and is connected to the guide wire hole 202. The diameter of the end of the tapered hole 4 connected to the guide wire hole 202 is the same, and the diameter of the end away from the guide wire hole 202 is larger than the diameter of the end connected to the guide wire hole 202, so that the guide wire can pass into the guide wire hole 202.

[0031] An auxiliary hole 5 is formed on the upper surface of the support plate 1 and communicates with the tapered hole 4. The diameter of the auxiliary hole 5 is half the diameter of the guide wire hole 202.

[0032] It should be noted that the guide wire hole 202, the tapered hole 4, and the auxiliary hole 5 are located on the same axis.

[0033] In summary, during use, the guide wire is inserted into the guide wire hole 202 through the tapered hole 4, and extends from the other end of the guide wire hole 202 to a preset distance. Then, the guide wire at the end away from the support base 201 is placed into the auxiliary hole 5. Subsequently, the index finger of one hand holds the support plate 1, and the thumb is placed on the push plate 302, so that the push plate 302 and the support plate 1 are located between the thumb and the index finger. Then, the thumb presses the push plate 302 downward. During the downward movement of the push plate 302, the return spring 304 is compressed until the push plate 302 drives the compression pad 306 to compress and fix the guide wire in the auxiliary hole 5. After the guide wire is fixed, the thumb is always pressing the push plate 302.

[0034] Then, the thumb of the other hand contacts the guidewire and pushes it against the outer wall of the auxiliary rod 205. Then, the guidewire is pressed firmly, causing it to be shaped on the surface of the auxiliary rod 205. Depending on the angle of the thumb pressing the guidewire, the final shape is... Figure 4The diagrams showing the shaping states of a, b, and c in the diagrams prevent doctors from failing to achieve the desired shape when shaping extremely fine guidewires manually or with a guide. This is especially difficult for novice doctors, who are prone to damaging the outer wall of the guidewire during repeated shaping. The diagrams improve the convenience for doctors during use and also shorten the time spent on shaping.

[0035] After the guidewire is shaped into a specified arc or bend, the thumb releases the pressure on the push plate 302, causing the compression pad 306 to disengage from the compression and fixation of the guidewire. Then, the end of the guidewire that has been shaped is pulled to extract the entire guidewire from the guidewire hole 202, the tapered hole 4, and the auxiliary hole 5. At this point, the guidewire shaping is complete.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
