Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically an ERCP guide wire fixation device. Background Art

[0002] ERCP, short for "retrograde cholangiopancreatography," specifically refers to retrograde cholangiopancreatography using a duodenoscope. ERCP is a highly specialized, minimally invasive hepatobiliary surgical technique requiring a high level of skill and expertise. Compared to traditional surgical procedures, it offers advantages such as less trauma, faster recovery, and more reliable therapeutic effects, serving both diagnostic and therapeutic functions. During ERCP, a guidewire is required for catheter insertion.

[0003] In current clinical procedures, two guidewires are usually inserted into the pancreatic duct and bile duct through the biopsy channel. Because the remaining part of the guidewire is too long, a separate medical staff member needs to coil the remaining guidewire and hold it in their hand while keeping it sterile, or hang it on a nearby medical device. There is a risk that the guidewire is easily confused and may fall off.

[0004] To address this, we designed a guidewire fixator based on current clinical needs. This device can securely hold excess guidewire coils during ERCP procedures, preventing confusion and easy dislodgement. It can also hold a sterile bag to secure the guidewire, ensuring sterile placement and making it highly practical. Utility Model Content

[0005] The purpose of this invention is to provide an ERCP guide wire fixation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An ERCP guide wire retainer includes an elastic retaining sleeve, with support arc plates for supporting the guide wire coil fixedly disposed on both sides of the elastic retaining sleeve. Clamping components for clamping the guide wire coil are disposed on the support arc plates, and indicator plates for distinguishing the guide wire are disposed on both sides of the elastic retaining sleeve.

[0008] As a further preferred embodiment of this utility model: connecting posts are provided on both sides of the elastic fixing sleeve, and fixing plates are fixedly provided at the ends of the connecting posts, with the supporting arc plate fixedly provided on the fixing plates.

[0009] As a further preferred embodiment of this utility model: the clamping assembly includes a movable clamping plate fitted on a supporting arc plate, the supporting arc plate passing through the movable clamping plate and slidably connected to the movable clamping plate, a sliding rod provided on the inner side of the movable clamping plate, the sliding rod passing through a fixed clamping plate and slidably connected to the fixed clamping plate, a baffle provided at the end of the sliding rod, and a spring provided between the baffle and the fixed clamping plate, the spring being fitted on the sliding rod.

[0010] As a further preferred embodiment of this utility model, a handle is provided on the movable clamp.

[0011] As a further preferred embodiment of this utility model, a hook is provided on the lower side of the fixing plate.

[0012] As a further preferred embodiment of this utility model: the elastic fixing sleeve is provided with two corresponding fastening plates, and bolt holes are provided on the fastening plates.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This guidewire fixator is designed with an elastic fixing sleeve, which can be fixed to the handle sheath of the biopsy port, making it close to the guidewire biopsy port entrance. This makes it convenient for medical staff to hang and operate the guidewire, and avoids the problem of the external guidewire being stretched too long and easily contaminated.

[0015] With the cooperation of the supporting arc plate and the two clamping plates, the supporting arc plate corresponds to the guide wire ring and can fit the arc-shaped inner ring of the guide wire ring, providing good support for the guide wire ring. The two clamping plates clamp and fix the guide wire ring, ensuring the stability of the guide wire ring when it is hung and preventing it from falling.

[0016] By designing hooks, sterile bags can be hung on the lower end of the fixed clamp when needed, so that the sterile bags can cover the guide wire rings, avoiding the problem of external guide wire leakage and easy contamination.

[0017] By setting up indicator signs, the guidewire coils and indicator signs can be hung on the corresponding support arc plate. Medical staff can distinguish the guidewires according to the indicator signs, avoiding the problem of guidewire confusion and ensuring the safety of clinical surgery.

[0018] In summary, this guidewire fixator has a simple, scientific, and reasonable structure, which can fix and fix the exposed guidewire during ERCP. It is convenient to fix, easy to pick up, and easy to distinguish, solving the problem of inconvenient fixation and easy confusion of existing ERCP guidewires, thus improving the safety and efficiency of clinical surgery.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0025] Please see Figure 1-4 This embodiment provides an ERCP guidewire fixation device, including an elastic fixing sleeve 1. To allow the elastic fixing sleeve 1 to be easily fitted onto the handle sleeve 13 at the lower end of the biopsy port handle of different diameters, two corresponding fastening plates 2 are provided on the elastic fixing sleeve 1. The fastening plates 2 have bolt holes 3, which can be used to tighten the two fastening plates 2 to ensure the tightness of the elastic fixing sleeve 1 after it is fitted. Support arc plates 6 for supporting the guidewire coil 16 are fixedly provided on both sides of the elastic fixing sleeve 1. Specifically, connecting posts 4 are provided on both sides of the elastic fixing sleeve 1, and fixing plates 5 are fixedly provided at the ends of the connecting posts 4. The support arc plates 6 are fixedly provided on the fixing plates 5. To ensure the stability of the guide coil 16 on the supporting arc plate 6 and prevent it from easily falling off, a clamping assembly for clamping the guide coil 16 is provided on the supporting arc plate 6. Specifically, the clamping assembly includes a movable clamping plate 7 fitted on the supporting arc plate 6, through which the supporting arc plate 6 passes and is slidably connected. A slide rod 10 is provided on the inner side of the movable clamping plate 7. Preferably, two slide rods 10 are provided, through which a fixed clamping plate 5 passes and is slidably connected. A baffle 11 is provided at the end of the slide rod 10, and a spring 12 is provided between the baffle 11 and the fixed clamping plate 5, with the spring 12 fitted on the slide rod 10. Additionally, to facilitate pulling the movable clamping plate 5 and easily placing and removing the guide coil 16, a handle 8 is also provided on the movable clamping plate 7.

[0026] In actual clinical applications, since two guidewires are used to enter the pancreatic duct and the bile duct, in order to avoid confusion between the guidewires, indicator plates 15 are set on both sides of the elastic fixation sleeve 1 to distinguish the guidewires 14. The indicator plates 15 are marked with the pancreatic duct and the bile duct respectively. After the guidewire 14 is inserted into the biopsy hole, the exposed guidewire coil 16 can be placed on the corresponding support arc plate 6 according to the indicator plate 15.

[0027] Meanwhile, in order to prevent medical staff from contaminating the exposed guide wire coil 16 during the operation, a sterile bag should be used to cover the guide wire coil 16. In order to hang the sterile bag, a hook 9 is provided on the underside of the fixing clamp 5.

[0028] like Figure 4 As shown, in actual clinical application, after the elastic fixing sleeve clip 1 is clipped onto the handle sheath 13 at the lower end of the biopsy port handle for puncturing the guidewire 14, the bolt is passed through the bolt hole 3 on the fastening plate 2, and the fastening plate 2 is pulled tight, so that the elastic fixing sleeve clip 1 clamps the outer wall of the handle sheath 13, thus realizing the installation of the guidewire fixator; after the guidewire 14 is inserted through the biopsy port on the handle, according to the indicator 15, the exposed guidewire ring 16 needs to be hung on the corresponding support arc plate 6. At this time, pull the handle 8 outward to move the movable clamp 7 away from the fixed clamp 5, and then hang the guidewire ring 16 on the support arc plate 6. Then, gently release the handle 8. Under the action of the spring 12, the movable clamp 7 and the fixed clamp 5 clamp the guidewire ring 16, thus fixing the guidewire ring 16; at the same time, a sterile bag can be put on the lower end of the guidewire ring 16, and the upper end of the sterile bag is hung on the hook 9 to prevent the sterile bag from falling off.

[0029] It should be noted that the upper end of the guidewire coil 16 that contacts the support plate 6 should be wrapped with medical padding to avoid wear on the guidewire 14 caused by the support plate 6 and the two clamps, which would affect the operation. This operation is a routine clinical operation that medical personnel in this field are familiar with in clinical applications, and will not be described in detail in this application.

[0030] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application.
