A soft guidewire for precise entry into the body

Abstract

The invention discloses a soft guide wire capable of accurately entering the body, which belongs to the technical field of medical devices and comprises an operating head, the top of which is fixedly connected with a protractor disc, and a driven roller is arranged above the protractor disc , and the position corresponding to the side orientation of the driven roller above the measuring angle plate is provided with a driving roller, through the designed first transfer shaft, driven roller, threaded cylinder, threaded rod, third transfer shaft, toggle cylinder, third With the mutual cooperation of bearings, universal hoses, nuts, fastening threaded barrels, elastic sleeves, and guide wire installation holes, guide wire bodies with various bending angles can be processed. Compared with manual bending, the product’s The pass rate has been improved, which can prevent the guide wire body from being worn out to produce burrs and other dangerous substances during the bending process, ensuring the quality of the guide wire body. The universal hose can also be used to statically fix the guide wire body. The bending operation of the guide wire main body can be completed at one time.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a soft guide wire that can accurately enter the body. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including the required computer software. The utility is mainly obtained through physical means, not through Pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role. [0003] If you want the guide wire to enter the human tissue channel accurately and smoothly, you must bend the tip of the guide wire at a certain angle in advance. At present, the bending of the guide wire is mostly done manually or automatically by machinery. There are still some shortcomings. Because the guide wire has a certain elasticity, i...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the bending of the guide wire is mostly carried out manually and automatically, there are still some deficiencies. Because the guide wire has certain elasticity, it needs to be kept after being bent. Stable for a period of time, it takes precious time of medical staff, and it is difficult for people to keep still for a long time, and in the process of bending with mechanical equipment, it is often caused by excessive friction or pressure. There are harmful substances such as burrs on the surface of the wire, and a soft guide wire that can accurately enter the body is proposed
