Problems solved by technology

[0002] Medical manipulators need matching operating equipment. Most of the operating equipment on the market are pedal-operated and handle-operated. Because the handle-operated is not inconvenient during surgery, most doctors choose the pedal-operated
The traditional pedal type is mostly controlled by a combination of multiple pedals, which has a huge structure, complicated operation, and is prone to problems such as stepping on the wrong foot.

Embodiment

[0025] A self-replicating two-way pedal structure, its structure is as follows Figure 1-2 As shown, it includes a pedal connecting seat 1 , a pedal base 2 , a bearing rod 3 , a bearing 4 and a tension spring 5 .

[0026] Both sides of the lower surface of the pedal connecting seat 1 are provided with connecting parts 11 , and the lower surface of the connecting part 11 is an arc-shaped structure, which matches the outer surfaces of both sides of the bearing rod 3 , and because it is installed at the connection point 12 of the tension spring, The tension spring 5 of the tension spring connection point 24 has a tension force, so that the connection part 11 can closely fit the bearing rod 3 . Therefore, it can be sleeved on the bearing rod 3 . Both sides of the upper surface of the pedal base 2 are provided with protruding parts 21 , and both ends of the bearing rod 3 are inserted into the connecting holes 22 opened on the protruding parts 21 to connect the pedal connecting sea...

Abstract

The invention relates to a self-recovering two-way pedal structure, which includes a pedal connecting seat, a pedal base, a bearing rod, a bearing and an extension spring. The pedal connecting seat is connected with the pedal base through the bearing rod and the bearing, and the There are tension springs installed at both ends to play the role of reset. Compared with the prior art, the present invention adopts a bidirectional structure, which is reasonable in design, strong and durable, small and light, and has good load-bearing performance.

Description

technical field [0001] The invention relates to the field of manufacturing a medical mechanical arm, in particular to a self-resetting two-way pedal structure. Background technique [0002] Medical robotic arms need matching operating equipment. Most of the operating equipment on the market are pedal-type and handle-type. Because handle-type is not inconvenient during surgery, most doctors choose pedal-type. The traditional pedal type is mostly controlled by a combination of multiple pedals, which has a huge structure, complicated operation, and is prone to problems such as stepping on the wrong side. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a self-resetting two-way pedal structure in order to overcome the above-mentioned defects in the prior art. The two-way structure is adopted, and tension springs are arranged at the front and rear, and the reset is realized by the tension of the tension spring. For the purpose of bidirection...
