For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

In order to solve the technical problem of how to realize that the electric wire 8b at the rear part of the probe 8 can be extended and contracted according to the needs of medical staff, so that the electric wire 8b does not influence the diagnosis of medical staff, as shown in fig. 1-3 and 5-7:

an ultrasonic diagnostic device comprises a base 1, a shell 2, a top plate 3, a wire winding and unwinding mechanism 4, a wire arranging mechanism 5, a wire leading mechanism 6, a placing mechanism 7 and a detecting head 8; the take-up and pay-off mechanism 4 comprises a take-up device 4a, a first locking mechanism 4b and a first unlocking mechanism 4 c; the recovery mechanism comprises a first partition plate 4a1, a second partition plate 4a2, a rotating groove 4a3, a rotating shaft 4a4, a coil spring 4a5, a box body 4a6 and a through hole 4a 7; the first partition board 4a1 is fixedly arranged on the base 1; the second partition plate 4a2 is fixedly arranged on the base 1, and a gap exists between the first partition plate 4a1 and the second partition plate 4a 2; the rotary grooves 4a3 are respectively arranged on the side walls at the opposite ends of the first partition plate 4a1 and the second partition plate 4a 2; the rotating shaft 4a4 is rotatably provided on the rotating groove 4a3 in the axial extending direction of the rotating groove 4a3, and the rotating shaft 4a4 is provided on the gap; the coil spring 4a5 is fixedly arranged on the side wall of the second partition plate 4a2 at the end close to the first partition plate 4a1 in the axial extension direction of the rotating shaft 4a 4; the box body 4a6 is fixedly arranged on the base 1 surrounding the coil spring 4a 5; the box body 4a6 is provided with a through hole 4a7 through which the rotating shaft 4a4 passes.

Based on the above-mentioned embodiment, this application shell 2 is fixed to be set up on base 1, and roof 3 is fixed to be set up at the top of shell 2. The tail of the probe 8 is fixedly provided with an electric wire 8b, and the side wall of the probe 8 is provided with a button 8 a. In the initial state, the probe head 8 is set on the placing mechanism 7, and the placing mechanism 7 is set on the top plate 3. The initial state here is when the medical personnel has not yet used the device for diagnosis. The end of the wire 8b remote from the probe 8 is disposed on the rotating shaft 4a4, and the wire 8b is wound around the rotating shaft 4a4 around the axis of the rotating shaft 4a 4. The wire arranging mechanism 5 is arranged on the base 1, and the wire arranging mechanism 5 is used for arranging the retracted electric wires 8b for the next taking. After the detecting head 8 is placed back in the placing mechanism 7, the coil spring 4a5 will drive the rotating shaft 4a4 to rotate, so that the electric wire 8b is wound on the rotating shaft 4a4, and the wire arranging mechanism 5 can assist the electric wire 8b to be wound on the rotating shaft 4a4 evenly and orderly. The base 1 is provided with the first partition plates 4a1 and the second partition plates 4a2, and the detecting heads 8 are arranged between the first partition plates 4a1 and the second partition plates 4a2, so that when diagnosis is performed, because a single detecting head 8 breaks down, diagnosis can be continued by using the standby detecting head 8, and the progress of diagnosis is ensured. In order to save space, a rotating groove 4a3 is formed in the inner side wall of the housing 2, then a first partition plate 4a1 and a second partition plate 4a2 are uniformly arranged in the axial extending direction of the rotating groove 4a3 in the housing 2, rotating grooves 4a3 are respectively formed in the side walls on both sides of the first partition plate 4a1 along the axial extending direction of the rotating groove 4a3 in the side wall of the housing 2, and both ends of the rotating shaft 4a4 close to one side of the side wall of the housing 2 are respectively arranged on the rotating groove 4a3 in the first partition plate 4a1 and in the rotating groove 4a3 in the side wall of the housing 2. The provision of cassette 4a6 prevents coil spring 4a5 from scratching cord 8b as coil spring 4a5 retracts cord 8 b. The recycling mechanism operates as follows, after the medical staff finishes the diagnosis, the button 8a on the side wall of the detecting head 8 is only needed to be pressed at the moment, so that the first unlocking mechanism 4c is activated, and the first locking mechanism 4b is unlocked by the first unlocking mechanism 4 c. When the first lock mechanism 4b is in the locked state, the rotation shaft 4a4 is not rotatable. So that the hinge 4a4 can be rotated after the first unlocking mechanism 4c is activated. When the medical staff uses the probe 8, the probe 8 will drive the electric wire 8b to be pulled out together. Since the two ends of the coil spring 4a5 are fixed to the box body 4a6 and the rotating shaft 4a4 respectively, the box body 4a6 is fixed, and the electric wire 8b is wound around the rotating shaft 4a4, so that the rotating shaft 4a4 is driven by the electric wire 8b to rotate, and the coil spring 4a5 is gradually driven to curl. This allows the rotary shaft 4a4 to be rotated by the coil spring 4a5 after the first unlocking mechanism 4c is unlocked. This causes the drawn-out electric wire 8b to be pulled back by the rotating shaft 4a4, and with the help of the wire arranging mechanism 5, the electric wire 8b is uniformly wound around the rotating shaft 4a 4. When medical personnel diagnose, when finding that detecting head 8 moves to a department that is close to detecting head 8 from a department of keeping away from the device, electric wire 8b in detecting head 8 rear portion must can the overlength to influence medical personnel's diagnosis, only need press button 8a this moment, make unnecessary electric wire 8b withdraw by pivot 4a4 can, so just realized that electric wire 8b in detecting head 8 rear portion can stretch out and draw back according to medical personnel's needs, so that electric wire 8b can not influence medical personnel's diagnosis.

Further, in order to solve the technical problem of how the first locking mechanism 4b can prevent the electric wire 8b from being brought back by the coil spring 4a5 when the medical staff takes out the probe 8 for use, as shown in fig. 4:

the first locking mechanism 4b comprises a first locking wheel 4b1, a pawl 4b2, a bearing rod 4b3 and a protruding shaft 4b 4; the first locking wheel 4b1 is fixedly arranged on the rotating shaft 4a4 along the axis of the rotating shaft 4a 4; the bearing rod 4b3 is fixedly arranged on the inner side wall of the shell 2 along the width direction of the base 1; the protruding shaft 4b4 is fixedly provided on one side of the bearing bar 4b 3; the pawl 4b2 is rotatably provided on the protruding shaft 4b4, and the ratchet wheel is engaged with the first lock wheel 4b 1.

Based on the above embodiment, one end of the first latch wheel 4b1 of the present application is connected to the side wall of the first bulkhead 4a 1. The length direction of the bearing bar 4b3 is parallel to the width direction of the housing 2. The protruding shaft 4b4 is a cylindrical structure, the head of the pawl 4b2 inclines downwards, the pawl 4b2 is meshed with the first locking wheel 4b1 under the action of self gravity, and the pawl 4b2 and the first locking wheel 4b1 form a ratchet mechanism by utilizing the unidirectionality of the ratchet mechanism. When the probing tip 8 drives the electric wire 8b to extend, the pawl 4b2 does not limit the first locking wheel 4b1, and when the electric wire 8b needs to be retracted but the pawl 4b2 does not unlock the first locking wheel 4b1, the rotating shaft 4a4 is not driven to rotate, so that the electric wire 8b is not pulled back by the coil spring 4a5, and the smoothness of the medical staff when the probing tip 8 is used for diagnosis is ensured. When unlocking is required, the first unlocking mechanism 4c is used to lift the pawl 4b2 by pressing the button 8a, so that unlocking is realized. Thus, when the medical staff takes the probe 8 out for use, the first locking mechanism 4b can ensure that the electric wire 8b cannot be brought back by the coil spring 4a5, so that the medical staff can make diagnosis more smooth, and the problem is solved.

Further, in order to solve the technical problem of how to unlock the first locking mechanism 4b after the first locking mechanism 4b is locked, as shown in fig. 3:

the first unlocking mechanism 4c includes a first magnet 4c 1; the first magnet 4c1 is fixedly disposed on the side of the load bearing bar 4b3 above the pawl 4b 2.

In the above embodiment, the first magnet 4c1 is preferably an electromagnet, and is not magnetic when not energized. When the medical staff diagnoses and feels that the electric wire 8b behind the probe 8 is too long, the button 8a can be pressed, then the first magnet 4c1 is electrified, so that the pawl 4b2 which is inclined due to the weight of the medical staff is attracted by the first magnet 4c1, the pawl 4b2 is disengaged from the first locking wheel 4b1, and after the first locking wheel 4b1 is not limited by the pawl 4b2, the rotating shaft 4a4 is driven by the coil spring 4a5, so that the electric wire 8b is retracted. When the medical staff retracts to the proper length, the power of the first magnet 4c1 can be cut off only by pressing the button 8a again, and the pawl 4b2 can be engaged with the first locking mechanism again under the action of the gravity of the pawl 4b2 due to the loss of the attraction of the first magnet 4c1, so that the unlocking function of the first locking mechanism 4b is realized. Thereby solving the above problems.

Further, in order to solve the technical problem of how the wire arranging mechanism 5 can evenly arrange the electric wires 8b on the rotating shaft 4a4, as shown in fig. 4 and 7:

the wire arranging mechanism 5 comprises a first sliding block 5a, a first sliding rail 5b, a fixed block 5c, a first spring 5d and a guide mechanism 5 e; the first slide rails 5b are symmetrically and fixedly arranged on the base 1 along the length direction of the base 1; the first sliding block 5a is arranged on the first sliding rail 5b in a sliding way; the fixed block 5c is fixedly arranged at two sides of the first partition plate 4a1 and the second partition plate 4a2, and a first gap is formed between the fixed block 5c and the first sliding block 5 a; the first spring 5d is arranged on the first gap, and two ends of the first spring 5d are respectively fixedly arranged on the sub first sliding block 5a and the fixed block 5 c; the guide mechanism 5e is provided at one end of the fixed block 5c near the first slider 5a in the width direction of the fixed block 5 c.

Based on the above embodiment, the elastic force of the first spring 5d of the present application should not be too large, otherwise the electric wire 8b may be damaged. In the initial state, the detection head 8 is also set on the placing mechanism 7. When medical personnel need use, medical personnel hold detecting head 8 and drive electric wire 8b and stretch out, and the winding can be pulled out gradually at last electric wire 8b of pivot 4a4, and electric wire 8b can be low first slider 5a compression first spring 5d, and first slider 5a and the contact end of electric wire 8b are opened there is the fillet, can further ensure like this that electric wire 8b can not be by first slider 5a scratch. After the use is completed, the coil spring 4a5 will drive the rotating shaft 4a4 to rotate, so that the electric wire 8b is wound on the rotating shaft 4a4 again, the first slider 5a will press the electric wire 8b wound on the rotating shaft 4a4, so that the electric wire 8b on the rotating shaft 4a4 can be wound only one turn at a time, and under the action of the first spring 5d, the first slider 5a will push the electric wire 8b to be uniformly wound on the rotating shaft 4a4, thus the technical requirement of uniformly arranging the electric wire 8b on the rotating shaft 4a4 is achieved, and the above problem is solved.

Further, in order to solve the technical problem of how to make the first slider 5a more stable during sliding, as shown in fig. 5:

the guide mechanism 5e includes a guide rod 5e1 and a guide hole 5e 2; the guide holes 5e2 symmetrically penetrate through the side wall of the first slider 5 a; the guide rod 5e1 is provided on the guide hole 5e2 in the axial extending direction of the guide hole 5e2, and one end of the guide rod 5e1 is fixedly provided on the side wall of the fixed block 5 c.

Based on the above-described embodiment, the present application guides the end of the lever 5e1 away from the fixed block 5c to be coplanar with the side of the first slider 5a away from the fixed block 5c in the initial state. Since the first slider 5a can only be slidably connected to the first sliding rail 5b of the base 1 without the guide rod 5e1, the first slider 5a will not slide smoothly, and the abrasion of the first slider 5a to the electric wire 8b is increased. With the guide rod 5e1, the first slider 5a can slide on the first slide rail 5b more stably, so that the first slider 5a is more stable when sliding, and the above problem is solved.

Further, in order to solve the technical problem of how to make the electric wire 8b be guided preliminarily when the medical staff pulls out or puts back the probe 8, so that the electric wire 8b is more smooth when being extended or retracted, as shown in fig. 8:

One end of the first gear 6f far away from the first lead wheel 6d is connected with the groove wall of the lead groove 6 c. One end of the second gear 6g away from the second lead wheel 6e is connected with the groove wall of the lead groove 6 c. When the electric wire 8b is taken out from the rotating shaft 4a4, the second sliding block 6b is driven to move along with the rotating shaft, so that the electric wire 8b between the rotating shaft 4a4 and the second sliding block 6b is ensured not to be inclined too much, and the second sliding block 6b and the electric wire 8b can move synchronously. First lead wire wheel 6d and second lead wire wheel 6e tightly the package clamp with electric wire 8b, when electric wire 8b drove first lead wire wheel 6d and second lead wire wheel 6e rotatory, first gear 6f and second gear 6g also can be together rotatory, the setting of first wheel of coming out is in order to guarantee that first lead wire wheel 6d and second lead wire wheel 6e can synchronous revolution, reduce the damage that causes electric wire 8b because skid, because second locking mechanism 6h and first locking mechanism 4b operate in step, so can guarantee more smoothly when electric wire 8b takes out, medical personnel's diagnosis and use have been made things convenient for, thereby above-mentioned problem has been solved.

Further, in order to solve the technical problem of how to prevent the electric wire 8b from moving back into the housing 2 through the wire leading mechanism 6 after the electric wire 8b is pulled out due to the certain distance between the wire leading mechanism 6 and the wire drawing and releasing mechanism 4, as shown in fig. 9-10:
