Waist ejector lifting mechanism

Abstract

The invention refers to a apical wale lifting gearing, applied in operation table, containing: -a driving worm, connected is a movable crank handle which is rotated by the drive of movable crank handle, this driving worm crank handle-driven warm wheel; -first chain gear, connected with the driven warm wheel; -secondly chain gear, the distance between it and first chain gear- scheduled distance;-spur gear,connected with the secondly chain gear;-vertical scale, meshed to the spur gear, the side of vertical scale is set with a apical wale;-driving-belt, placing in the first and secondly chain gear; drive shaft, a side connected with the first gear;-fourthly chain gear, connected with the other side of drive shaft;-fifthly chain gear, the distance between it and fourthly gear -scheduled distance;-auxiliary driving-belt, connected with the fourthly and fifthly chain gear;-auxiliary spur gear, connected with the fifthly chain gear;-auxiliary vertical scale, meshed to the auxiliary spur gear, one side is connected with the apical wale.

Description

technical field [0001] The invention relates to a lifting mechanism, which is applied to a medical operating table, in particular to a waist lifting mechanism for controlling the lifting state of the top waist. Background technique [0002] The development of today's science and technology has a very important direction, which is to think about how to bring humans a stronger body, and then extend people's limited life. The ancients said: There are unpredictable things in the sky, and people have misfortunes and blessings. It is inevitable that people must be treated by surgery because of accidental injuries or some diseases. At this time, the environment in which doctors operate is extremely important. However, even if doctors have extremely superb medical skills, it is useless if they lack good surgical instruments. The key to the doctor's smooth operation is the operating table. [0003] The patient can lie on the operating table, and then illuminate the affected part t...

Problems solved by technology

[0005] Although the above-mentioned previous proposals can operate reasonably and have certain effects, their disadvantages lie in the fact that many related components are complex in action and have the disadvantages of high production costs.

[0006] Secondly, among the components used in the previous case or commercially available products, most of the kidney bridges are made of bakelite or acrylic, while the transmission shaft across both sides of the operating table is made of metal. X-rays are blocked during irradiation, which has caused long-term troubles for medical staff

In addition, due to the characteristics of the material, the load of the kidney bridge plate is limited, and it may be broken or tilted due to the unbearable weight due to long-term use

In this way, the displacement of the renal bridge will seriously affect the operation. However, in the operation where human life is at stake, no mistakes are allowed; therefore, such problems must be completely resolved
