The mechanical arm has the advantage of being capable of moving in multiple degrees of freedom, and therefore the mechanical arm is a good alternative to manpower. Therefore, it is necessary to design a new device to realize the fixation of the ultrasonic probe at the end of the mechanical arm.

Chinese patent (patent application No. CN201822047295.4) discloses a clamp for an ultrasonic probe, comprising: a clamping assembly operable to clamp the ultrasound probe; the ultrasonic probe comprises a driving assembly for driving the clamping assembly to open or close and a transverse sliding assembly for movably mounting the clamping assembly, wherein the driving assembly and the transverse sliding assembly are matched to enable the ultrasonic probe to be mounted in the clamping assembly and clamped; the bottom plate is used for fixedly mounting the transverse sliding assembly; the vertical sliding assembly is used for vertically and movably mounting the bottom plate to the mounting base; and a spring mounted between the vertical slide assembly and the base plate. The clamping assembly of the clamp can be opened and closed conveniently through the rotary screw rod, and has certain universal applicability. The spring installed between the vertical sliding assembly and the bottom plate has buffering capacity, and when the probe is in contact with a human body, discomfort to a patient can be avoided. However, the clamping assembly of the device is in direct contact with the ultrasonic probe, and the clamped part of the probe is easily damaged after being clamped.

Chinese patent (patent application No. CN201920284086.3) discloses an ultrasonic robot probe fixing device, which comprises a clamp assembly connected with a horn of an ultrasonic robot, wherein the clamp assembly comprises a right clamp and a left clamp, the right clamp and the left clamp are connected through a fixing assembly, and a slot for inserting a probe is formed between the right clamp and the left clamp. The utility model discloses a set up the anchor clamps subassembly of being connected with ultrasonic robot's horn, by coupling assembling with left anchor clamps, probe and right anchor clamps are connected, set up left bolster between probe and left anchor clamps, set up right bolster between probe and right anchor clamps, avoid the clamp of probe to hinder or the scratch, it is connected with last anchor clamps to set up the connecting plate, it is connected with left anchor clamps to go up anchor clamps, realize the fixed of probe, and the rotation that adopts first connecting piece drives all second connecting pieces and rotates and loosen or screw up, be convenient for change the probe, and realize the probe that can compatibly fix the different grade type. However, the clamping of the device needs the meshing of the master gear and the slave gear, the clamp cannot be clamped due to the fact that the tooth height is small and the phenomenon of loose meshing is prone to occur, and the installation of the master gear and the slave gear in the device is complex.

Disclosure of Invention

The invention aims to provide an auxiliary mechanical arm fixed ultrasonic probe clamp, which solves the problems that the conventional ultrasonic probe is easy to damage a clamping part and unstable in clamping.

In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a fixed supersound probe anchor clamps of supplementary arm, includes base, connecting piece, probe anchor clamps A and probe anchor clamps B, all be equipped with the recess on probe anchor clamps A, the probe anchor clamps B, two the recess encloses the centre gripping chamber that closes formation centre gripping ultrasonic probe, the internal diameter in centre gripping chamber and ultrasonic probe's external diameter phase-match, the base passes through connecting piece and probe anchor clamps A, probe anchor clamps B bolted connection.

Furthermore, buffer parts are arranged between the probe clamp A and the probe clamp B and the ultrasonic probe respectively, and the buffer parts are arranged in the grooves.

Further, the buffer part is made of sponge.

Furthermore, the buffer part adopts an annular air bag, and one side of the air bag is provided with a rubber belt.

Furthermore, the depths of the grooves on the probe clamp A and the probe clamp B are gradually narrowed from bottom to top.

Furthermore, the probe clamp A and the probe clamp B are fixed through four bolts matched with gaskets, elastic pads and nuts.

Compared with the prior art, the beneficial effect of this scheme:

according to the scheme, the ultrasonic probe is fixed through the probe clamp A and the probe clamp B, the groove is formed between the probe clamp A and the probe clamp B, and meanwhile, the problem that the ultrasonic probe is damaged or scratched by the clamp is solved by means of the buffer piece; meanwhile, only four bolts of M5 multiplied by 35 are matched with elastic pads and nuts to be fixed with a probe clamp B through the probe clamp A, and the ultrasonic probe fixing device can adapt to ultrasonic probes with different sizes. The damage of current auxiliary machinery arm supersound probe anchor clamps to the probe is solved to this scheme, improves the gear engagement and probably has the insecure situation of meshing, and the structure is simple relatively, and general adaptability is better, and the dismouting is nimble.

Detailed Description

The present invention will be described in further detail below by way of specific embodiments:

reference numerals in the drawings of the specification include: the ultrasonic probe comprises a base 1, a connecting piece 2, a probe clamp A3, a probe clamp B4, a groove 5, an ultrasonic probe 6, a buffer 7 and a rubber belt 8.

Example 1

As shown in figures 1 to 4: the utility model provides a fixed ultrasonic probe anchor clamps of supplementary arm, includes base 1, connecting piece 2, probe anchor clamps A3 and probe anchor clamps B4, and a plurality of screw holes have been seted up to circumference on the base 1, can make base 1 and arm end-to-end connection through the bolt to it is fixed with ultrasonic probe 6 and arm. The connecting piece 2 is an L-shaped steel plate, four mounting holes are symmetrically formed in the long side and the short side of the connecting piece 2, and therefore the connecting piece 2 can be connected with the probe clamp B4 and the base 1 through the mounting holes. Semicircular grooves 5 are formed in the probe clamp A3 and the probe clamp B4, the two grooves 5 enclose a clamping cavity for clamping the ultrasonic probe 6, and the inner diameter of the clamping cavity is matched with the outer diameter of the ultrasonic sleeve head. The buffers 7 are adhered in each groove 5, the buffers 7 in the embodiment are made of sponge, the length of each buffer 7 is the same as that of the corresponding probe clamp A3 or B4, threaded holes corresponding to the mounting holes in the long side of the connector 2 are symmetrically formed in the same positions of the probe clamp A3 and the probe clamp B4, and therefore the probe clamp A3 and the probe clamp B4 can be connected and fixed with the connector 2 through bolts.
