Abstract
The utility model discloses a can be at flexible axle of work under strong magnetic field environment, it relates to medical instrument and robot field, replaces traditional carbon steel steel wire as the main material by 304 nonrust steel wires, and there is a 1mm wire -core at the center, and inlayer is formed around the wire -core compact winding by 3 0.5mm steel wires side by side, and two three -layers form around the reverse winding of preceding one deck with 8 same specification steel wires by 6 respectively, and the surface cover has the nonmetal to protect the hose, and the end is equipped with the shaft coupling, the utility model discloses be convenient for realize the normal transmission of the interior flexible axle of high -intensity magnetic field, convenient to use, simple structure, the transmission is reliable, has improved the security of work, has lengthened the life of machine.
Description
Technical field
This utility model relates to a kind of flexible axle that can work under strong magnetic field circumstance, belongs to medical robot technical field.
Background technology
In view of the fast development of medical skill, in medical robot, be also gradually integrated into some medical advanced technologies, such as: mr imaging technique (MRI).Consider that MRI is to the sensitivity of lesion detection, high spatial resolution, outstanding soft-tissue imaging function, surgical operation machine auxiliary robot under MRI real-time navigation becomes worldwide study hotspot, and current Chinese scholars has designed Duo Kuan MRI robot.Wherein partial robotic is in order to realize curve transmission, and some local application flexible axle instead of plain shaft.
Due in the very powerful magnetic field of the indoor existence of nuclear magnetic resonance, NMR machine and nuclear magnetic resonance check, therefore, person of being equipped with cardiac pacemaker, and after vascular surgery, leave the patient such as metal clip, metal rack person, definitely forbid to make nuclear magnetic resonance check.Equally, for requiring high-precision medical robot, some metal parts is affected by magnetic fields makes it produce small displacement, may reduce equipment life, even can lead to great malpractice.
Summary of the invention
For the problems referred to above, the technical problem that this utility model solves is to provide a kind of flexible axle that can work under strong magnetic field circumstance.
This utility model replaces traditional carbon steel steel wire as the main material of twisting flexible axle by 304 stainless steel silks, centered by a 1mm wire-core, flexible axle ground floor is become around wire-core compact winding side by side by 3 0.5mm steel wires, and two or three layers are formed around front one deck reverse-winding by 6 and 8 same specification wires respectively, flexible axle length is 300mm, also can as required from Row sum-equal matrix length, its surface cover has nonmetal protection flexible pipe be used for protecting rotary flexible shaft and keep lubrication, also can be used as guiding and the support of flexible axle simultaneously, end is provided with shaft coupling, be used for connecting the equipment such as motor,
The beneficial effects of the utility model are: this utility model is convenient to the normal transmission realizing flexible axle in high-intensity magnetic field, easy to use, and structure is simple, and reliable transmission, improves the safety of work, extends the service life of machine.
Accompanying drawing explanation
For ease of illustrating, this utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of flexible axle in this utility model.
In figure: 1-shaft coupling; 2-flexible axle; The nonmetal protection flexible pipe of 3-.4-wire-core; The 1st layer of steel wire that 5-is wound around around wire-core; 6-the 2nd layer of reverse-winding steel wire; 7-the 3rd layer of reverse-winding steel wire.
Detailed description of the invention
This utility model replaces traditional carbon steel steel wire as the main material of twisting flexible axle (2) by 304 stainless steel silks, centered by a 1mm wire-core (4), flexible axle ground floor (5) is become around wire-core compact winding side by side by 3 0.5mm steel wires, and two or three layers of (6) (7) are formed around front one deck reverse-winding by 6 and 8 same specification wires respectively, flexible axle (2) can as required from Row sum-equal matrix length, its surface cover has nonmetal protection flexible pipe (3) be used for protecting rotary flexible shaft (2) and keep lubrication, also can be used as guiding and the support of flexible axle (2) simultaneously, end is provided with shaft coupling (1).During use, can directly the shaft coupling (1) of end be connected to need transmit power corresponding mechanism on, using flexible pipe (3) as the support of flexible axle (2) and guider, under being placed in strong magnetic field circumstance.Because 304 rustless steels are non-magnetic steel, therefore no longer need the device in isolated magnetic field.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The exemplary illustration of present embodiment just to this patent, does not limit its protection domain, and those skilled in the art can also change, as long as no the spirit exceeding this patent, in the protection domain of this patent its local.
Claims (2)
1. the flexible axle that can work under strong magnetic field circumstance; its composition comprises: 304 rustless steel wire-cores (4); 304 stainless steel silks (5) that ground floor 3 is wound around side by side; 304 stainless steel silks (6) that the second layer 6 is wound around side by side; 304 stainless steel silks (7) that third layer 8 is wound around side by side; the 3rd layer of described surface is also overlapped and is had nonmetal protection flexible pipe (3); be used for protecting rotary flexible shaft and keep lubrication; also can be used as guiding and the support of flexible axle simultaneously; described flexible axle (2) end is connected with shaft coupling (1), is used for connecting motor device.
2. a kind of flexible axle that can work under strong magnetic field circumstance according to claim 1, is characterized in that: described flexible pipe is made up of the nonmetallic materials of magnetic compatibility.
