In the application of ultrasonic interventional puncture, the most important is a puncture frame of an ultrasonic probe besides various ultrasonic probes. Generally, in the ultrasonic intervention operation, firstly a couplant is coated on the surface of a transducer of an ultrasonic probe, then an ultrasonic probe sleeve is covered on the ultrasonic probe, and finally a puncture frame is fixedly arranged on the surface of the ultrasonic probe through the probe sleeve. Therefore, the ultrasonic probe can be completely covered and isolated, and the ultrasonic probe is prevented from being polluted in the operation process. However, since the covering parts of the ultrasonic probe sleeve and the ultrasonic probe are generally regular rectangles, and the appearance of the ultrasonic probe is generally a relatively round and irregular shape, the ultrasonic probe sleeve can be wrinkled in different degrees when covering the surface of the ultrasonic probe, and meanwhile, the ultrasonic probe sleeves produced by different manufacturers are different in thickness.

In addition, the screw is easily rusted even after a long time use, which is extremely disadvantageous in a severe medical environment. In addition, because the buckle fixed mode is accomplished through the deformation of elastomeric element when the installation, consequently need exert certain power when installation or dismantlement puncture frame, the elastomeric element deformation process produces very big extrusion frictional force with ultrasonic probe surface simultaneously, can produce the damage of certain probability to ultrasonic probe surface. Moreover, in the general ultrasonic operation process, the work of installing the puncture rack is completed by assistant doctors with low experience or strength (such as female doctors), so the use experience of the doctors is poor.

In addition, in the puncture carriage for a probe according to the related art, there is also a problem that the puncture carriage can be repeatedly used to cause cross interference.

Detailed Description

The invention will be described in detail below with the aid of exemplary embodiments with reference to the accompanying drawings.

The basic construction of a probe piercing carriage assembly according to the present invention is described in detail below, first with reference to fig. 1.

Fig. 1 illustrates the basic construction of a probe piercing rack assembly according to the present invention. In the illustrated embodiment, the probe-piercing carriage assembly may include a piercing carriage 100 and a probe 200, wherein the piercing carriage 100 is securely affixed to the surface of the probe 200 by an attachment means. In the illustrated embodiment, the probe 100 is an ultrasound probe. By mounting the puncture holder 200 on the ultrasound probe, the puncture needle can be guided to a target site of a human body under ultrasound guidance. It is to be understood that although the present invention has been described with reference to an ultrasound probe as an example, the probe 200 may be any other probe, such as an infrared probe, without departing from the spirit and scope of the present invention. Furthermore, although the arrangement of the present invention is particularly effective in the case of intracavity probes, it is to be understood that probes according to the present invention may also be extracavity probes without departing from the spirit and scope of the present invention.

Figures 2 and 3 schematically illustrate perspective and cross-sectional views, respectively, of a piercing carriage in the probe piercing carriage assembly of figure 1. Fig. 4 and 5 show in detail a perspective view of the hook and tab of the attachment means of the piercing frame.

Referring to fig. 2 to 5, the puncture stand 100 may include a stand body 1 and an attachment device. In the illustrated embodiment, the attachment means includes a first hook 11 and a second hook 12 provided on the frame body 1, and the attachment means further includes a tab 2, as clearly shown in fig. 5, the tab 2 including a catch 221 and a step catch 231. According to the exemplary embodiment shown in fig. 2 and 3, the first and

second hooks

11 and 12 are provided on the frame body 1 of the puncture frame 100, and the catch 221 and the stepped catch 231 are connected to the first and

second hooks

11 and 12 in use so as to firmly fix the probe. It is also conceivable that the catch 221 and the step catch 231 are provided on the rack body 1, and the rack body 1 provided with the catch 221 and the step catch 231 is connected with the catch 221 and the step catch 231 provided on another fixing device in use so as to firmly fix the probe. The term "in use" refers to a state in which the hook and the tab are fixed together to firmly fix the probe, that is, a state in which the probe 200 is assembled with the rack 100 to form a probe rack assembly.

Preferably, the catch 221 and the first hook 11 are fixed to each other by integral forming, in such a way as to reduce the assembly processes associated with the assembly of the catch 221 and the first hook 11. However, it is also possible to provide that the catch 221 and the first hook 11 are fixed to each other by a fastener, or that the catch 221 and the first hook 11 are fixed to each other by welding and adhesion. It should be noted that the fixing manner of the catch 221 and the first hook 11 is not limited as long as the fixing therebetween can be achieved.

As shown in fig. 5, preferably, the ladder buckle 231 is shown as a flat band. However, it is contemplated that the stepped buckle 231 may have other cross-sectional shapes than a belt shape, such as a square, a circle, or other irregular shape, as long as the stepped buckle 231 can perform the release prevention locking function as described in detail below in cooperation with the second hook 12. The anti-release locking function provided according to an embodiment of the present invention will be described in detail below with reference to fig. 2 to 7.

As shown in fig. 5 and 6, the stepped buckle 231 is alternately provided on one of its side surfaces with a plurality of first stopper surfaces 2312, which are shown as substantially horizontal surfaces, and a plurality of first inclined surfaces 2311, which are shown as inclined surfaces at acute angles thereto. It should be noted that, in this case, the step buckle 231 is provided with the first inclined surface 2311 uppermost in the radial direction on the side surface thereof where the first stopper surface 2312 and the first inclined surface 2311 are provided, so as to facilitate initial penetration of the step buckle 231 into the second hook 12. Wherein the term "radial direction" refers to the direction relative to the extension direction (axial direction) of the carrier body when the mounting is completed.

In addition, as shown in fig. 7, the second hook 12 may be provided with a catching hole 112 through which the stepped buckle 231 moves and a resilient piece 111 disposed in the catching hole 112. The resilient tab 111 is somewhat flexible to accommodate movement of the step buckle 231. In the illustrated embodiment, the resilient tab 111 is provided with a second inclined surface 1111 and a second stop surface 1112 that cooperates with the first stop surface 2312.

According to an exemplary embodiment, the second stop surface 1112 is a substantially horizontal surface similar to the first stop surface 2312, and the second chamfer 1111 is a chamfer at an acute angle to the second stop surface 1112. Preferably, the angle formed by the first inclined surface 2311 and the first stopper surface 2312 is substantially the same as the angle formed by the second inclined surface 1111 and the second stopper surface 1112, so that the step buckle 231 can be slid along the striking plate 11 with a small force.

According to the above configuration, when the step buckle 231 is pushed in the fastening direction in which the probe is fastened in the buckle position hole 112, the first inclined surface 2311 of the step buckle 231 pushes the second inclined surface 1111 of the resilient piece 111 provided in the hook 12, thereby elastically and flexibly deforming the resilient piece 111 having flexibility. As the stepped buckle 231 continues to move in the tightening direction within the buckle position hole 112, the first inclined surface 2311 is pushed away from the second inclined surface 1111. At this time, since the force applied by the first inclined surface to the elastic sheet 111 is released, the elastic sheet 111 is reset, and the first stop surface 2312 is engaged with the second stop surface 1112. The step catch 231 is prevented from moving in the release direction to release the probe due to the blocking action of the second stop surface 1112 against the first stop surface 2312. In this way, according to the puncture rack 100 provided by the present invention, when the attachment device attaches the probe, the attachment device is only allowed to move in the tightening direction (the direction in which the probe is tightened) and, at the same time, the attachment device is prevented from moving in the releasing direction (the direction in which the probe is released), thereby realizing the release prevention locking function for the probe.

Further, by providing a plurality of first inclined surfaces 2311 and a corresponding plurality of first stop surfaces 2312 on the side surface of the step buckle 231, the step buckle 231 can be engaged with the second stop surface 1112 on the resilient piece 111 at a plurality of locking positions corresponding to the plurality of first stop surfaces 2312 to achieve the above-described release-preventing locking function. In this way, the degree of tightness of fit of the pull buckle 2 and the probe 200 is adjusted by providing a plurality of locking positions, so that the self-adaptive capacity during installation of the puncture rack is provided.

It is contemplated that various modifications may be made to the foregoing embodiments without departing from the scope and spirit of the present invention. For example, the stepped buckle 231 may be provided with a first slope 2311 and a first stopper surface 2312 on more than one side surface thereof. It should be noted that when the first slope 2311 and the first stopper surface 2312 are provided on more than one side surface of the stepped buckle 231, the arrangement of the first slope 2311 and the first stopper surface 2312 on the respective side surfaces should be synchronized. Further, it is also conceivable that the first and

second slopes

2311 and 1111 are configured in other manners as long as the engagement of the first and

second slopes

2311 and 1111 enables the step buckle 231 to move in the tightening direction within the buckle position hole 112 with a small force, for example, the first and

second slopes

2311 and 1111 may be provided in a smooth arc shape. Likewise, it is also contemplated that the first and second stop surfaces 2312 and 1112 could be otherwise configured, for example, the first and second stop surfaces 2312 and 1112 could include grooves and protrusions, respectively, to further ensure the anti-release locking function described above.

As shown in fig. 5, according to an embodiment of the present invention, the attachment means may comprise a hoop 21 that can be wrapped around the probe, which hoop 21 is flexible to enable plastic deformation to some extent, so as to be able to better adapt to the shape of various probes. According to an exemplary embodiment, the hoop 21 is connected to the frame 1 by means of a snap 221 and a step 231, wherein the hoop 21 is arranged to bulge in a radial direction from the lower surface of the frame 1 to be able to tightly wrap the probe when the attachment device is assembled. Preferably, the flexible hoop 21 is provided with rupturing means operable to rupture the hoop 21. In the embodiment shown in the figures, the breaking means is shown as a breaking line 211, wherein the stiffness of the hoop 21 at this breaking line 211 is smaller than the stiffness of the hoop 21 at the remaining positions. In this way, after the puncture rack 100 is used, the anchor ear 21 can be broken by breaking the wire 211, so that the attachment device cannot be mounted for the second time, thereby avoiding the risk of cross-infection due to repeated use of the puncture rack. Preferably, the attachment means may comprise a pull handle 24 connected to the break line 211, by means of which pull handle 24 the operation of the breaking means can be easily achieved.

To facilitate the operation of the attachment device, according to an exemplary embodiment, the tab 2 of the present invention may further comprise a first platform 22 and a second platform 23, wherein the catch 221 is provided on the first platform 22 and the step buckle 231 is provided on the second platform 23, and the hoop 21 is provided between the first platform 22 and the second platform 23, whereby the connection of the flexible hoop 21 with the catch 221 and the step buckle 231 may be better achieved and the operation of the attachment device may be optimized. Specifically, when attaching the puncture frame 100 of the present invention to the probe 200, the buckle 221 and the first hook 11 can be first fixedly fastened (in the case that the buckle 221 and the first hook 11 are integrally formed, this step can be omitted), then the hoop 21 disposed on the tab 2 is covered on the surface of the probe and the probe is wrapped, and then the stepped buckle 231 and the second hook 12 disposed on the frame body 1 are locked in cooperation to achieve the purpose of firmly mounting the puncture frame 100 on the surface of the ultrasonic probe for the puncture operation. In this way, the ease and efficiency of assembly of the lancing mount 100 with the probe 200 is greatly improved compared to adjusting the attachment of the lancing mount 100 with the probe 200 from the position of the catch 221 and the position of the step catch 231, respectively, when in use.

The above-described embodiments should not be construed as limiting the scope of the invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
