Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a doctor control platform base. BACKGROUND

[0002] With the development of technology, minimally invasive surgery has been more and more widely used for its small surgical trauma, short recovery time and less pain for patients. Laparoscopic surgery robot has also developed rapidly with the promotion of minimally invasive surgery. It is a new type of minimally invasive surgery equipment, which is composed of a doctor control platform, a patient surgery platform and an image platform. The upper end of the doctor control platform has a master control mechanical arm for hand operation, and the lower end is provided with a pedal for foot operation. The surgeon controls the master control mechanical arm on the doctor control platform by hand, and controls the surgical mechanical arm on the patient surgery platform by operating the master control mechanical arm with both hands and using the foot to operate the control pedal (or button, etc.), so as to make the surgical mechanical arm perform complex actions such as cutting, separating and suturing in the patient's body, thereby completing the surgery.

[0003] The doctor control platform can be deployed by artificial pushing. When pushing the doctor control platform, in order to ensure that the doctor control platform has passability to certain terrain, there needs to be a certain height difference between the universal casters of the control console and the lowest point of the chassis. After the doctor control platform is deployed in place, the universal casters need to be locked to provide a more stable operation platform. At the same time, the pedal base provided with various control pedal switches needs to be lowered to the ground to make the surgeon more comfortable when operating with feet.

[0004] The existing doctor control platform needs two operating mechanisms to control the locking and lowering of the pedal base, which makes the whole device more complicated. Or only the doctor control platform locking mechanism is provided, and there is no pedal lifting mechanism, so the pedal is always at a high position. When the surgeon operates the control pedal switch, the legs are suspended off the ground, which is not very comfortable. For example, the existing patent CN207870961U proposes a doctor control console of a surgical robot with simple structure, which can effectively improve the operation comfort and accuracy of doctors.

At this time, the synchronous pedal 2 is at the high stable stop point 31. When the external force is applied to the synchronous pedal 2, the limiting groove sleeve 203 is lowered, and the limiting shaft 29 can only move left along the limiting groove under the limitation of the upper side of the limiting groove, reaching the position of the right second point, i.e., the high-low conversion unstable stop point 32. At this time, the synchronous pedal 2 is at the lowest position, but at this position, when the external force is removed, the synchronous pedal 2 will move left along the limiting groove under the joint action of the upward pulling force and the lower side of the limiting groove, and finally reach the stable state at the position of the right third point, i.e., the low stable stop point 33. At this time, the synchronous pedal 2 is at the lowest position that can be stably stopped. When the external force is applied to the synchronous pedal 2 again, the limiting shaft 29 can only move left along the limiting groove again under the limitation of the upper side of the limiting groove, reaching the position of the right fourth point, i.e., the low-high conversion unstable stop point 34. At this position, when the external force is removed, the synchronous pedal 2 will move left along the limiting groove again under the joint action of the upward pulling force and the lower side of the limiting groove, returning to the position of the right first point, i.e., the high stable stop point 31, completing a movement cycle. Therefore, when the synchronous pedal 2 is at the high stable stop point, and the synchronous pedal 2 is stepped down, it will reach the lowest but unstable position (high-low conversion unstable stop point 32). When the synchronous pedal 2 is released, it will be stably stopped at the low stable stop point 33, and at the same time, the control pedal assembly also falls to the ground, improving the comfort of use. Then, the synchronous pedal 2 is stepped down again, and the synchronous pedal 2 will reach the lowest but unstable position (low-high conversion unstable stop point 34) again. At this time, when the synchronous pedal 2 is released, it will be stably stopped at the high stable stop point 31, i.e., it returns to the initial state, and at the same time, the control pedal assembly also hovers at a certain height, ensuring the passability of the doctor when controlling the platform to move.

[0075] As shown in Figure 5 The control pedal support 10 includes a main support 1001, a connecting rod receiving plate 1002, and a second mounting plate 1003. The main support 1001 is located below the rear side of the U-shaped base 1. The connecting rod receiving plate 1002 is vertically arranged on both sides of the main support 1001. The second mounting plate 1003 is horizontally arranged on the outer side of the connecting rod receiving plate 1002. The synchronous pedal hanging column 11 is arranged on the second mounting plate 1003. The two ends of the connecting rod receiving plate 1002 are provided with lugs, and the lugs at both ends are connected to the articulated connecting rod 14 through a hinge shaft 15. The articulated connecting rod 14 is connected to the brake connecting rod 12, and the brake connecting rod 12 close to the synchronous shaft 8 (the two brake connecting rods located at the rear side of the U-shaped base 1) is fixed to the rear brake synchronous shaft seat 6. As shown in Figure 2As shown, the U-shaped base 1 is provided with front brake shaft seats 25 on both sides away from the synchronous shaft 8, and the brake connecting rods 12 (two brake connecting rods located on the front side of the U-shaped base 1) away from the synchronous shaft 8 are fixed on the front brake shaft seats 25; The caster 24 is arranged below the U-shaped base 1 close to the rear brake synchronous shaft seat 6, and the caster 24 is arranged below the U-shaped base 1 close to the front brake shaft seat 25. Four casters 24 are arranged below the U-shaped base 1, and the four casters 24 form a quadrilateral support doctor control platform. The four casters 24 are all casters with central control brakes. Figure 7 As shown, the brake connecting rod 12 is connected to the rear brake synchronous shaft seat 6 or the front brake shaft seat 25 through the brake shaft 13. The brake connecting rod 12 is clamped by the expansion sleeve to clamp the brake shaft 13. The rotation of the brake connecting rod 12 drives the rotation of the brake shaft 13. The rotation of the brake shaft 13 can lock or release the caster 24. When the control pedal assembly follows the synchronous foot pedal assembly to make lifting movement, the connecting rod receiving plate 1002 drives the brake connecting rod 12 to swing, thereby driving the brake shaft 13 to rotate. The rotation of the brake shaft 13 can control the locking or releasing of the central control universal caster. In this way, the lifting of the control pedal assembly and the locking or releasing of the central control universal caster can be realized at the same time by a single external force.

[0076] The caster with central control brake has an adjusting member inside. An inner hexagonal hole is arranged on the adjusting member, and the end of the brake shaft is an outer hexagonal shape. The end of the outer hexagonal brake shaft is inserted into the adjusting member. The rotation of the brake shaft drives the rotation of the adjusting member. The rotation of the adjusting member realizes the locking or releasing of the caster. The specific structure of the caster with central control brake is a prior art, which can be referred to patent CN204845381U, and will not be described in detail here.

[0077] In other embodiments, the four casters can also be two casters with central control brakes and two directional wheels. The two casters with central control brakes are both arranged below the open end of the U-shaped base or below the closed end of the U-shaped base. The two directional wheels are arranged below the other end of the U-shaped base. Correspondingly, the brake shaft seat, brake shaft and brake connecting rod corresponding to the directional wheels can be removed.

[0078] In other embodiments, when the four casters are all casters with central control brakes, if the brake force provided by two brake casters is enough to make the doctor control platform stop stably, the front brake shaft seat and the corresponding brake shaft and brake connecting rod can also be removed, or the rear brake synchronous shaft seat and the corresponding brake shaft and brake connecting rod can also be removed.

The driven gear 20, the driving gear 21 and the driving mechanism are all fixed on the main support 1001, the driving mechanism drives the driving gear 21 to rotate, and the driving gear 21 is engaged with the driven gear 20. The driven gear 20 is connected with the lead screw 19 through threads, and the main support 1001 is provided with a through hole corresponding to the lead screw 19, and the lead screw 19 can make extension and retraction movement in the through hole. The driving mechanism drives the driving gear 21 to rotate, and in turn drives the driven gear 20 to rotate, and the rotation of the driven gear 20 drives the lead screw 19 to make extension and retraction movement, and in turn drives the lead screw fixing sleeve 18 to make linear motion, and the lead screw fixing sleeve 18 drives the control pedal mounting seat 16 to make linear motion, so as to realize accurate control of the position of the control pedal mounting seat 16.

[0081] The second balance assembly 17 is provided with a second guide mechanism on both sides, and the second guide mechanism comprises a moving part and a guide part. One of the moving part and the guide part is arranged on the U-shaped base 1, and the other of the moving part and the guide part is arranged on the control pedal assembly. The moving part and the guide part cooperate to provide a guide function for the movement of the control pedal assembly.

[0082] In this embodiment, the moving part is a second guide shaft 22, and the guide part is a second guide sleeve 27. The second guide shaft 22 is arranged on the second mounting plate 1003, and the second guide sleeve 27 is arranged below the U-shaped base 1 corresponding to the second guide shaft 22.
