Description

Technical Field

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

[0002] Endoscopic retrograde cholangiopancreatography (ERCP) is one of the main minimally invasive treatments for biliary and pancreatic diseases. It involves inserting an endoscope through the mouth into the duodenum, guiding specialized instruments through the duodenal papilla into the bile duct or pancreatic duct, and then, under X-ray fluoroscopy, injecting contrast agent for imaging, inserting a sub-endoscopy / ultrasound probe for observation, and collecting exfoliated cells / tissue. This process allows for the diagnosis of biliary and pancreatic diseases, and the implementation of appropriate interventional treatments based on the diagnosis. During ERCP, the operator uses a guidewire to explore the lumen of the bile duct or pancreatic duct by manipulating it through obstructions or stenosis, guiding the appendages through to improve the success rate. Therefore, successful guidewire placement is crucial for ERCP success. Clinically, manipulating the guidewire to difficult locations often requires the operator to perform certain degrees of rotation, shaking, and gentle twisting. Due to the thinness of the guidewire, the contact area between the operator's hand and the guidewire is limited, making it difficult for the operator to perform precise manipulations such as full rotation and shaking, in addition to insertion and withdrawal. Therefore, difficult ERCP cannulation often involves longer operation time, higher complication rate, and lower success rate.

[0003] In view of this, it is necessary to design a guide wire control device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a guide wire control device that can fully fix the guide wire without damaging it.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A guidewire control device, comprising:

[0007] The first locking block has a first vertical bend on one side;

[0008] The second locking block is detachably connected to the first locking block. The second locking block has a second vertical bend on one side corresponding to the first vertical bend, so that when the two locking blocks are connected to form a columnar structure, the first bend and the second bend form a curved axial through hole located in the middle of the columnar structure, and the input end and output end of the axial through hole are located at the axis of the columnar structure; the axial through hole has at least two bends.

[0009] As a further improvement of this utility model, the outer periphery of the columnar structure is also provided with a rough portion for increasing friction.

[0010] As a further improvement of this utility model, the rough part is a sawtooth structure arranged circumferentially along the columnar structure.

[0011] As a further improvement of this utility model, the rough portion includes a plurality of protrusions spaced apart circumferentially and axially along the columnar structure.

[0012] As a further improvement of this utility model, the columnar structure is also provided with a hand-held part for assisting in the disassembly and installation of the columnar structure.

[0013] As a further improvement of this utility model, the hand-held part includes a first notch provided on the top surface and / or bottom surface of the first locking block and a second notch provided on the top surface and / or bottom surface of the second locking block, such that when the two locking blocks are connected to form a columnar structure, the corresponding first notch and second notch on the two locking blocks form a recessed area with a diameter that gradually increases along the direction away from the center of the columnar structure.

[0014] As a further improvement of this utility model, the recessed area is connected to the axial through hole.

[0015] As a further improvement of this utility model, the diameter of the axial through hole is greater than or equal to the diameter of the guide wire.

[0016] As a further improvement of this utility model, the two locking blocks are magnetically connected.

[0017] As a further improvement of this utility model, the columnar structure is cylindrical.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model incorporates a vertically bent portion on the locking block, connecting two locking blocks to form a columnar structure with a curved axial through hole in the middle. The guide wire is then placed within this axial through hole. Utilizing the flexibility of the axial through hole and the guide wire's inherent plasticity, the guide wire is positioned in a curved shape within the axial through hole, effectively increasing the contact area between the guide wire and the columnar structure. Furthermore, the curved path effectively reduces the probability of the guide wire detaching from the columnar structure, thus ensuring relative stability between the guide wire and the columnar structure. This curved locking method of the utility model guarantees a stable connection between the guide wire and the columnar structure without damaging the guide wire.

[0020] 2. The guide wire control device of this utility model can amplify the operation of guide wire rotation, shaking and other operations. Taking rotation as an example, the synchronous rotation of the guide wire can be achieved by rotating the columnar structure. Compared with rotating the guide wire by hand, it is easier to apply force by holding the relatively large columnar structure, thereby improving the precision of operation.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0028] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] Please see Figures 1-2 As shown, this utility model provides a guidewire control device, including:

[0030] The first locking block 10 has a first vertical bend 11 on one side;

[0031] The second locking block 20 is detachably connected to the first locking block 10. The second locking block 20 has a second vertical bending portion 21 on one side corresponding to the first vertical bending portion 11. When the two locking blocks are connected to form a columnar structure, the first bending portion and the second bending portion form a curved axial through hole 40 located in the middle of the columnar structure. The input end and output end of the axial through hole 40 are located at the axis of the columnar structure. The axial through hole 40 has at least two bending segments 30.

[0032] For example, such as Figure 2As shown, the axial through hole 40 is provided with three bent sections 30.

[0033] Specifically, the outer periphery of the columnar structure is also provided with a rough portion to increase friction. For example, the rough portion is a serrated structure 50 arranged circumferentially along the columnar structure. In other embodiments, the rough portion can be configured in other forms, such that its presence enhances the friction between the operator and the guide wire 60 control device; for example, the rough portion includes a plurality of protrusions spaced apart circumferentially and axially along the columnar structure.

[0034] Specifically, the columnar structure is also provided with a handle for assisting in the disassembly and installation of the columnar structure. For example, the handle includes a first notch 12 on the top surface of the first locking block 10 and a second notch 22 on the top surface of the second locking block 20, such that when the two locking blocks are connected to form a columnar structure, the first notch 12 and the second notch 22 on the two locking blocks form a recessed area with a diameter that gradually increases along the direction away from the center of the columnar structure.

[0035] For example, depending on the force application habits, a first notch 12 can also be provided on the bottom surface of the first locking block 10, and a second notch 22 can also be provided on the bottom surface of the second locking block 20, so that the top and bottom surfaces of the columnar structure formed by the connection of the two locking blocks have recessed areas to assist in the application of force and facilitate the disassembly and installation of the two locking blocks.

[0036] For example, the recessed area is connected to the axial through hole 40, and the recessed area and the axial through hole 40 are coaxially arranged.

[0037] For example, both the first notch 12 and the second notch 22 are arc-shaped, making the resulting recessed area resemble a spherical crown with a perforation near the axial through hole 40. The perforation has the same diameter as the axial through hole 40. By setting the notch to an arc shape, the fit between the operator's hand and the notch can be increased, thereby improving the ease of applying force while enhancing operational comfort.

[0038] For example, the diameter of the axial through hole 40 is equal to the diameter of the guide wire 60.

[0039] For example, the two locking blocks are magnetically connected.

[0040] For example, the columnar structure is cylindrical.

[0041] In use, the guide wire 60 is placed on the first vertical bend 11 of the first locking block 10, and the second locking block 20 is brought close to the first locking block 10 and connected by magnetic attraction. This allows the first vertical bend 11 and the second vertical bend 21 to form a curved axial through hole 40 with a diameter equal to that of the guide wire 60, thereby locking the guide wire 60 in the columnar structure.

[0042] like Figure 3 As shown, since the input and output ends of the axial through hole 40 are both located at the axis of the columnar structure, the guide wire 60 can be rotated synchronously by controlling the rotation of the columnar structure. When disassembly is required, the operator's thumb is placed on the first notch 12 and the second notch 22 respectively and force is applied to separate the first locking block 10 and the second locking block 20, thereby unlocking the guide wire 60.

[0043] This invention places the guidewire 60 within the axial through hole 40, which increases the contact area between the operator and the guidewire 60 using the guidewire 60 control device. By controlling the guidewire 60 control device, the related actions of the guidewire 60 can be controlled, making it easier to apply force. This, in turn, helps the operator to complete actions such as rotation, shaking, and twisting, improving the precision of the operation. At the same time, the rough part can enhance the friction between the operator and the guidewire 60 control device, further improving the stability of the operator's grip on the guidewire 60 control device, thereby increasing the success rate of difficult ERCP cannulation.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
