Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an ultrasonic probe suspension device. Background Technology

[0002] An ultrasonic probe is a device that emits and receives ultrasonic waves during ultrasonic testing; it is also known as an ultrasonic detector or ultrasonic probe. In an ultrasonic imaging system, it is a core component used to emit and receive ultrasonic waves and convert the signals into a visual image. After use, the ultrasonic probe needs to be suspended and retracted.

[0003] The existing device achieves automatic probe reset by winding the probe circuit around the two disc spring seats, but the following problems still exist in actual operation:

[0004] 1. During the automatic retraction of the disc spring seat, the spring force is mainly relied on. In actual operation, when the spring releases energy quickly, it will generate a large impact force on the connected object. Therefore, when the operator releases the hand, the disc spring seat may cause the probe to collide with the insertion port used to limit the probe, which may result in damage or even destruction of the probe.

[0005] 2. In order to facilitate the movement of the suspension device, the existing device is fixed on the bracket. However, in actual operation, the bracket occupies a large area and is quite high. This can obstruct personnel movement and cause the device to be easily damaged by collisions. Utility Model Content

[0006] To address the aforementioned issues, the present invention aims to provide an ultrasonic probe suspension device that solves the problem of the probe easily colliding with the probe storage base during automatic retraction in existing devices.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An ultrasonic probe suspension device includes a probe storage base for storing the probe, a winding mechanism fixed to the top of the probe storage base for automatically storing the probe wire, and a fixing mechanism located on one side of the winding mechanism for fixing the winding mechanism; the winding mechanism includes a protective storage box fixed to the top of the probe storage base, a circumferentially rotatable winding roller horizontally installed inside the protective storage box, an automatic winding assembly located above the winding roller inside the protective storage box, and a pair of speed reduction drive assemblies symmetrically arranged between the automatic winding assembly and the winding roller. The automatic winding assembly includes a fixed rod horizontally fixed above the winding roller inside the protective storage box, a circumferentially rotatable rotating sleeve rod horizontally installed inside the protective storage box and covering the fixed rod, and several disc springs spaced along the length of the fixed rod and fixed at both ends to the fixed rod and the rotating sleeve rod respectively; each set of reduction drive assembly includes a rack ring fixedly sleeved at one end of the rotating sleeve rod and a reduction gear fixedly sleeved at the corresponding side end of the winding roller and meshing with the rack ring; the diameter of the rack ring in each set of reduction drive assembly is smaller than that of the reduction gear.

[0009] More preferably, the winding roller is also symmetrically fixed with limiting discs at both ends, and the two limiting discs are covered with an anti-wear layer on the side close to each other.

[0010] More preferably, the fixing mechanism consists of four suction cups respectively fixed to the four corners of one side of the protective storage box.

[0011] More preferably, the probe housing is surrounded by an elastic rubber layer.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, by meshing between a rack ring with a smaller diameter and a reduction gear with a larger diameter, when the disc spring drives the rack ring to rotate through the rotating sleeve, the reduction gear drives the take-up roller to rotate at a slower speed, thereby reducing the winding speed of the line fixed on the take-up roller, thus alleviating the degree of collision between the probe and the probe storage seat when the probe retracts, and minimizing the possibility of damage or even destruction caused by the probe colliding with the probe storage seat;

[0014] 2. In this utility model, the device is fixed by four suction cups, which reduces the area occupied by the device and avoids obstructing the movement of people as much as possible. On the other hand, fixing it by suction cups can also prevent the bracket from tilting or the device from falling and breaking due to collisions, thus improving the safety when using the device.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] An ultrasonic probe suspension device includes a probe storage base 1 for storing the probe, a winding mechanism 2 fixed to the top of the probe storage base 1 for automatically storing the probe wire, and a fixing mechanism 3 located on one side of the winding mechanism 2 for fixing the winding mechanism 2. The winding mechanism 2 includes a protective storage box 21 fixed to the top of the probe storage base 1, a circumferentially rotatable winding roller 22 horizontally installed inside the protective storage box 21, an automatic winding assembly 23 located above the winding roller 22 inside the protective storage box 21, and a pair of speed reduction drive assemblies 24 symmetrically arranged between the automatic winding assembly 23 and the winding roller 22. The automatic winding assembly 23 includes... The package includes a fixed rod 231 horizontally fixed above the take-up roller 22 inside the protective storage box 21, a rotating sleeve rod 232 rotatably mounted horizontally inside the protective storage box 21 and covering the fixed rod 231, and several disc springs 233 spaced along the length of the fixed rod 231 and fixed at both ends to the fixed rod 231 and the rotating sleeve rod 232 respectively; each set of reduction drive assembly 24 includes a rack ring 241 fixedly sleeved at one end of the rotating sleeve rod 232 and a reduction gear 242 fixedly sleeved at the corresponding end of the take-up roller 22 and meshing with the rack ring 241; the diameter of the rack ring 241 in each set of reduction drive assembly 24 is smaller than that of the reduction gear 242.

[0025] When using this device, the probe's wiring is fixed to the take-up roller 22. When the probe is needed, it is taken out of the probe storage seat 1 and pulled down. At this time, the probe's wiring drives the take-up roller 22 to rotate. Under the meshing action of the rack ring 241 and the reduction gear 242, the rotating sleeve 232 rotates in the opposite direction. At this time, the disc spring 233 is gradually tightened. After use, the probe is released. At this time, under the action of the disc spring 233, the rotating sleeve 232 rotates, thereby driving the take-up roller 22 to wind up under the action of the rack ring 241 and the reduction gear 242, so that the probe's wiring is wound on the take-up roller 22.

[0026] As a possible implementation of this solution, preferably, the take-up roller 22 is also symmetrically fixed with limiting discs 221 at both ends, and the two limiting discs 221 are covered with an anti-wear layer 222 on the side close to each other; in this device, the probe's circuit is located between the two limiting discs 221, and the distance between the two limiting discs 221 is equal to the diameter of the circuit, so that when the take-up roller 22 takes up the probe circuit, the circuit is wound into a disc-shaped structure, so as to avoid the occurrence of the circuit tangling during the winding process as much as possible.

[0027] As a possible implementation of this solution, preferably, the fixing mechanism 3 consists of four suction cups 31 respectively fixed at the four corners of one side of the protective storage box 21; by setting the four suction cups 31, the protective storage box 1 and the probe storage seat 1 can be fixed to the side wall of the table, the side of the baffle, etc., which can adjust the position of the probe according to the doctor's personal habits, making it convenient to operate, and can also achieve convenient movement.

[0028] As a possible implementation of this solution, preferably, the probe storage base 1 is surrounded by an elastic rubber layer 11; the setting of the elastic rubber layer 11 can further reduce the collision between the probe and the probe storage base 1 when the probe is stored in the probe storage base 1, and further extend the life of the probe.

Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
