Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a catheter guidewire processing device for an interventional catheter room. Background Art

[0002] Interventional therapy is a new type of high-tech minimally invasive treatment technology, which has the characteristics of small trauma, multiple indications, definite efficacy, and fast postoperative recovery. It is an important development trend of future medicine. Among interventional treatment technologies, vascular interventional therapy is the subdivision with the highest technical requirements and entry barriers. The guide wire consists of an inner and outer part. The cavity in the center of the spring is the inside of the guide wire, which is equipped with a steel wire core. According to needs, the material can be stainless steel wire, nickel-titanium memory alloy, or both. The front end of the steel wire core gradually becomes thinner, and the tip of the very thin steel wire core is welded to the end of the spring, and then the tail end of the steel wire core is welded to the tail end of the spring and polished smooth. The outer layer of the traditional guide wire is made of high-quality stainless steel wire wound on a spring lathe. The steel wire is required to be smooth, tough, and elastic, and the winding must be uniform and tight, neatly arranged, and consistent in density. This spring should be able to withstand repeated bending and will not break under a certain force. The lengths of guide wires include 150cm, 180cm, 260cm, and 300cm. According to the hardness of the guide wire, it is divided into ordinary guide wires, hard guide wires, and super hard guide wires. During surgery, several types of guide wires are often used alternately.

[0003] The Chinese patent application number 202022337350.0 discloses a postoperative interventional guidewire processing device. Although the utility model has a simple structure, can conveniently complete the postoperative guidewire winding work, and can adjust the guidewire accommodation volume, it is worthy of vigorous promotion and use. However, the utility model has the disadvantage that during the winding process, when the medical staff interrupts the winding work due to other events, the rotating turntable does not have a self-locking function, and the elastic action of the guidewire causes the rotating turntable to rotate in the opposite direction, and the previously wound guidewire loosens; secondly, there are disadvantages such as inconvenience in disassembling the wire and the winding tube after winding and inconvenience in adjusting the uniformity of the wire winding.

[0004] In view of this, the present inventor proposes a catheter guidewire processing device for an interventional catheter laboratory. Utility Model Content

[0005] The utility model aims to provide a catheter guide wire processing device for an interventional catheter room, so as to solve the problem in the prior art that the wound guide wire becomes loose due to interruption when medical staff wind the guide wire.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a catheter guidewire processing device for an interventional catheter room, comprising a fixed frame and an adjusting assembly arranged on the inner wall of the fixed frame, the adjusting assembly is detachably connected to a wire-taking roller shaft, the inner wall of the fixed frame is rotatably connected to a worm gear, the worm gear is meshed with a worm rotatably connected to the fixed frame, one end of the worm gear is provided with a crank penetrating the fixed frame, the wire-taking roller shaft is fixedly connected to the worm gear through the adjusting assembly, the inner wall of the fixed frame is provided with a cross bar, and the cross bar is sleeved with a guide sleeve.

[0007] Principle of the technical solution: When in use, pass one end of the cleaned guide wire through the guide sleeve and wrap it around the take-up roller shaft. Turn the crank, the crank drives the worm to rotate, and the rotating worm drives the worm wheel to rotate, which in turn drives the adjustment component and the take-up roller shaft to rotate, and then winds the guide wire onto the take-up roller shaft; when medical staff are interrupted by other events, the worm wheel and worm have a self-locking effect, which can prevent the elasticity of the guide wire from driving the worm wheel to rotate in the opposite direction, thereby causing the wound guide wire to loosen. Secondly, the adjustment component can adjust the angle so that the take-up shaft moves back and forth left and right during the take-up process, and under the action of the guide sleeve, the guide wire can be evenly wound on the take-up roller shaft.

[0008] The worm gear is provided with a transmission shaft, and the transmission shaft is slidably connected to the rotation of the transmission shaft with a spring, and the transmission shaft is slidably connected to the rotation of the transmission shaft with a spring.

[0009] By adopting the above technical solution, the angle between the adjustment plate and the fixed frame can be adjusted, so that the take-up roller can achieve horizontal reciprocating motion during the rotation process; when in use, the adjusting bolt is rotated to push the adjusting plate to rotate around the pin shaft, so that the adjusting plate is tilted, and the crank is turned to drive the take-up roller to rotate. The rotating take-up roller drives the turntable and the adjusting rod to rotate. As the distance between the rotating adjusting rod and the adjusting plate changes, the take-up roller moves back and forth along the guide rod when it rotates under the adjustment action of the spring, thereby achieving uniform take-up.

[0010] Furthermore, a limit block is provided at the free end of the guide rod, and a sliding block is provided at the transmission sleeve, and the sliding block is fixedly connected to a spring.

[0011] The above technical solution can prevent the turntable 2 from being separated from the transmission shaft and prevent the turntable 2 from being stuck when moving back and forth along the transmission shaft, thereby ensuring smooth sliding.

[0012] Furthermore, retaining rings are provided at both ends of the take-up roller shaft, elastic pipe clamps are provided on opposite surfaces of the two retaining rings, and a protective layer is provided on the inner wall of the elastic pipe clamp.

[0013] The above technical solution can prevent the end of the wire from being loosened due to elasticity at the beginning or end of wire collection due to the wire end being unrestricted.

[0014] Furthermore, a one-way valve is provided in the guide sleeve.

[0015] The adoption of the above technical solution can further prevent the wound guide wire from loosening due to interruption during the wire-reeling process under the action of elasticity.

[0016] Furthermore, a support rod penetrating the second rotating disk is provided on the side of the sliding block away from the worm gear, and the driven rotating shaft is inserted into the support rod.

[0017] By adopting the above technical solution, the stability of the entire device can be improved.

[0018] Furthermore, a handle is provided on the top of the fixing frame.

[0019] By adopting the above technical solution, medical staff can hold the fixed frame with one hand and turn the crank with the other hand during the wire collection process to stabilize the support frame.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. Through the coordinated setting of the one-way valve, the elastic pipe clamp, the worm and the worm gear, it can effectively prevent the interruption of the wire reeling process and the loosening of the wound wire under the influence of its elastic force after the reeling is completed.

[0022] 2. By adjusting the setting of the component, the take-up roller can move back and forth left and right during the rotation process, so as to achieve uniform take-up. Secondly, the take-up roller is detachably connected, which makes it convenient to store the wound wire in a sealed box after disassembly of the take-up roller, so as to prevent the clean guide wire from being contaminated.
