Description

TECHNICAL FIELD

[0001] The utility model relates to the field of guide wire fixing, in particular to an intraoperative storage device for guide wire. BACKGROUND

[0002] In interventional surgery, the use of guide wire is a key operation. Guide wire is usually used to guide other medical devices (such as balloon, stent, etc.) into the target site. In complex lesion surgery, different guide wires are often needed according to the classification and characteristics of guide wire. After the guide wire is in place through the lesion, it needs to be avoided from excessive displacement, otherwise it may cause blood vessel injury or fall out of the lesion and be difficult to pass through again. At the same time, the guide wire usually needs a long length to adapt to the complex operation space in the operation. This leads to the management of guide wire in the operation becoming an important problem. At present, medical staff usually winds the guide wire into multiple turns and fixes it on the operating table with wet gauze. Although this method can ensure the smooth use of guide wire to a certain extent, it also brings many inconveniences.

[0003] The existing wet gauze fixing method not only takes time and effort, but also often needs to be operated repeatedly in actual operation. When the guide wire is taken again, the medical staff needs to untie the wet gauze, which is not only cumbersome but also time-consuming. Although some storage devices can solve part of the guide wire management problem, they are often designed to be large, complex in structure and not flexible enough to adapt to the requirements of space and time in the operation process, and are rarely applied in clinical practice. These devices not only occupy the operation space of the operating table, but also may affect the operation convenience and operation efficiency of medical staff. SUMMARY

[0004] The present scheme provides an intraoperative storage device for guide wire, which comprises a fixed seat with a sticky surface on the bottom surface, a longitudinal clamping gap in the center for fixing the guide wire, and a sponge layer inside the clamping gap to enhance the fixing effect and protect the surface of the guide wire. The device has a water injection hole for washing the blood stains on the guide wire with heparin saline, and a one-way valve to prevent backflow. The fixed seat is composed of first and second clamping parts with streamlined shape to improve clamping force. The above design improves the convenience and practicality of guide wire management, effectively improving the efficiency of guide wire storage management in the operation.

[0005] The present scheme specifically adopts the following technical means:

[0006] An intraoperative storage device for guide wire, comprising a fixed seat, the bottom surface of the fixed seat is provided with a sticky surface for attaching to the operating table, a longitudinal clamping gap is formed in the center of the fixed seat, which is used to fix the guide wire after winding, and a sponge layer is arranged inside the clamping gap. Preferably, the sponge layer is a nano sponge cleaning layer.

[0007] Further, a water injection hole is formed in the upper side of the fixed seat and communicates with the longitudinal clamping gap, heparin saline is injected into the water injection hole to flush the blood stains on the surface of the guide wire.

[0008] Further, the water injection hole is a one-way valve.

[0009] Further, the fixing seat is composed of a first clamping part and a second clamping part, and the first clamping part and the second clamping part are tightly formed into a longitudinal clamping seam with clamping force.

[0010] Further, the first clamping part and the second clamping part are in streamline shape in transverse section.

[0011] Further, a water injection hole is formed on the upper side of each of the first clamping part and the second clamping part.

[0012] Further, the fixing seat is made of silica gel.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The longitudinal clamping seam allows the guide wire to be fixed at a certain position, prevents the guide wire from being contaminated or falling to the ground during the operation, and facilitates the operator when the guide wire is used again, thereby improving the operation accuracy and safety. The adhesive surface of the bottom surface of the fixing seat allows the device to be stably attached to the operating table, thereby reducing the problems that may be caused by the movement of the device during the operation. The cross-sectional design of the fixing seat with high middle and low sides effectively reduces the cross-sectional area of the device and reduces the overall quality of the fixing device. This design improves the portability of the device.

[0015] The nano sponge cleaning layer can form a buffering and protective effect in the clamping seam, and the injection of heparin saline through the water injection hole can clean the blood stains on the surface of the guide wire, preventing the guide wire from being stuck to the surface of the guide wire, thereby preventing the guide wire from being difficult to pass through the catheter, balloon, stent and other accessories. The one-way valve designed water injection hole can avoid backflow and ensure the efficiency of the water injection process.

[0016] Silica gel is used as the material of the fixing seat, which can provide sufficient flexibility and elasticity, so that the device can firmly hold the guide wire and is not easy to cause damage to the guide wire. In addition, the silica gel material also has good chemical resistance and high temperature resistance, and is suitable for use in a medical environment. BRIEF DESCRIPTION OF DRAWINGS

[0020] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. The following embodiments and the features in the embodiments can be combined with each other without conflict.

[0021] See also Figure 1 The holder 1 of the intraoperative guidewire storage device of the present invention is made of X-ray-transparent silicone material. Its bottom surface is provided with an adhesive surface 2 for secure attachment to the operating table. A longitudinal slit 3 is defined through the center of the holder 1 for clamping and securing the guidewire coil. A nanosponge layer 5 with a diameter of 0.5 cm is positioned within the slit 3 to provide excellent friction and ensure stable guidewire retention.

[0022] In this embodiment, the fixing base 1 is divided into a first clamping portion 101 and a second clamping portion 102. These two clamping portions are closely attached to form a longitudinal gap 3. The cross-sections of the clamping portions 101 and 102 are designed to be streamlined, with a high center and low sides. This reduces the transverse cross-sectional area of ​​the fixing base 1 and thus the weight of the device. The sponge layer 5 within the gap 3 has excellent water-retention properties, effectively protecting the guidewire surface and achieving non-destructive fixation of the guidewire.

[0023] In practice, the guidewire coil is inserted into the longitudinal slit 3 to secure it. When removing the guidewire, one end remains, while the other end can be removed to clean blood stains from the guidewire surface. This securement of the guidewire coil within the longitudinal slit 3 ensures the stability of the guidewire. The user can inject heparinized saline solution into the injection port 4 via a syringe to clean stains from the guidewire surface within the slit 3. The injection port 4 is designed as a one-way valve to prevent backflow and ensure smooth injection. The aperture matches the nipple of a 10ml syringe.

[0024] See also Figure 2 , which shows the side structure of the fixing base 1. Water injection holes 4 are provided on the upper side of the fixing base 1. These water injection holes 4 are two independent holes, located above the first clamping part 101 and the second clamping part 102 respectively. The water injection channel is between the water injection holes 4 and the longitudinal slit 3. This design allows the longitudinal slit 3 to be evenly soaked with heparinized saline after water injection, thereby improving the cleaning effect. The nanostructure of the sponge layer 5 can effectively absorb blood stains, and the material will not absorb moisture on the surface of the guide wire, thereby avoiding affecting the hydrophilic function of the guide wire.

[0025] The guide wire operation in -situ receiving device has simple structure, reasonable material selection, convenient and fast operation, no additional mechanical buckle is needed in use, the guide wire is directly clamped into the gap 3 and can be fixed, and the operation can be quickly completed when taking. Through the design, the fixing device can not only firmly fix the guide wire, but also has the function of cleaning the bloodstains on the surface of the guide wire, thereby improving the overall efficiency of the operation. The utility model discloses simple and convenient, economic and practical, can provide convenient and effective operation experience for doctors, and guarantee the safety and cleanliness of the guide wire in use.
