As shown in fig. 1, in a first aspect, an embodiment of the present application provides a connection structure of a puncture frame (for convenience of description, hereinafter referred to as connection structure 100), which relates to the technical field of medical apparatuses, and is mainly applied to an extracorporeal puncture frame, and is used for being matched with an ultrasonic probe to guide a puncture needle to puncture.

As shown in connection with fig. 1 to 3, the connection structure 100 mainly includes: a body 110, a slider 120, and a button 130.

Wherein, the body 110 defines a receiving cavity 113 having an insertion port 114, and defines a limiting space 117 for placing the ultrasonic probe, the sliding member 120 is slidably disposed in the receiving cavity 113, i.e., the sliding member 120 is capable of sliding in the receiving cavity 113, and the sliding member 120 defines an open cavity 121 capable of receiving a sensor for detecting the position of the ultrasonic probe on the body surface or in the body, so that the medical staff can more accurately position and collect the tissue sample of the patient.

One side of the slider 120 is provided with an elastic portion 122, and an end of the elastic portion 122 remote from the slider 120 is coupled to a cavity wall of the accommodating cavity 113. The button 130 is movably disposed through the body 110, at least a portion of the button 130 is disposed in the accommodating cavity 113 and is connected to a side of the sliding member 120 away from the elastic portion 122, that is, the elastic portion 122 and the button 130 are respectively disposed on two opposite sides of the sliding member 120 in the sliding direction.

Thus, when the button 130 is pressed, the button 130 drives the slider 120 to slide so that the open cavity 121 is aligned with the insertion port 114, at this time, the sensor can be inserted into the open cavity 121 through the insertion port 114, and when the button 130 is released, the elastic part 122 drives the slider 120 to reset so that the open cavity 121 is dislocated from the insertion port 114, so as to limit the sensor from sliding out of the insertion port 114.

For example, when the sensor is installed, the button 130 is pressed first, so that the button 130 drives the slider 120 to slide and compress the elastic portion 122 until the open cavity 121 is aligned with the insertion port 114, then the sensor is placed in the open cavity 121 of the slider 120 through the insertion port 114, and then the button 130 is released, so that the slider 120 is reset under the driving of the elastic portion 122, and the open cavity 121 is dislocated with the insertion port 114, at this time, the sensor is blocked by the edge of the insertion port 114 and cannot slide out from the insertion port 114, so that the installation process of the sensor is completed.

When the sensor is removed, the button 130 is also first pressed until the open cavity 121 of the slider 120 is aligned with the insertion port 114 to unblock the sensor from the edge of the insertion port 114, and then the sensor is removed from the open cavity 121, thus completing the removal process of the sensor.

In the related art, the puncture frame comprises a puncture frame body and a protective cover, wherein the puncture frame body is provided with a containing groove for placing a sensor, and the periphery of the protective cover is fixed at the position of the containing groove through screws for covering and protecting the sensor. However, when installing and dismantling the sensor, the screw needs to be screwed, and the process is time-consuming and laborious, resulting in lower installation efficiency and dismantling efficiency of the sensor, affecting the use experience.

Compared with the screwing mode, the connecting structure 100 provided by the embodiment enables the open cavity 121 of the sliding piece 120 to be aligned with the insertion port 114 or misplaced with the insertion port 114 by pressing and loosening the button 130, so that medical staff can conveniently install and detach the sensor, the convenience is higher, and the use experience is improved.

It should be noted that, the end of the elastic portion 122 away from the sliding member 120 is coupled to the cavity wall of the accommodating cavity 113, which means that the end of the elastic portion 122 away from the sliding member 120 may be fixedly connected with the cavity wall of the accommodating cavity 113, or may be detachably connected with the cavity wall of the accommodating cavity 113, for example, clamped, threaded, bonded, or interference fit, or may, of course, abut against the cavity wall of the accommodating cavity 113, so as to achieve sliding reset of the sliding member 120.

As shown in fig. 3, in one embodiment, the body 110 is provided with a through hole 115 communicating with the receiving cavity 113, the button 130 is provided at the through hole 115, and the sectional area of the button 130 is gradually increased in a direction approaching the slider 120 in a direction perpendicular to the moving direction of the slider 120.

Thus, when the button 130 moves to the preset position along the direction away from the elastic portion 122, the edge of the through hole 115 abuts against the circumference of the button 130, so as to limit the movement of the button 130, that is, play a role in preventing the button 130 from moving continuously, so that the slider 120 is prevented from shaking in the accommodating cavity 113 during the use of the connection structure 100, and the stability of the sensor after installation is improved.

Of course, for the above embodiment, a limiting post may be further disposed at the position of the through hole 115, and when the button 130 moves to the preset position along the direction away from the elastic portion 122, the limiting post abuts against the slider 120, which can also limit the slider 120 to move continuously, so as to improve the stability of the sensor after installation.

With continued reference to fig. 3, in one embodiment, the slider 120 is provided with a sliding portion 123, the cavity wall of the receiving cavity 113 is provided with a guiding portion 1131, and the sliding portion 123 is slidably connected to the guiding portion 1131.

In this embodiment, by the arrangement of the guiding portion 1131, when the button 130 is pressed or released, the sliding portion 123 can stably slide along the guiding portion 1131, that is, the guiding portion 1131 cooperates with the sliding portion 123 to play a role in guiding the sliding of the sliding member 120, thereby improving the stability and smoothness of the sliding member 120.

Further, the sliding portion 123 is a sliding rib, and the guiding portion 1131 is a guiding groove adapted to the shape of the sliding rib, and when the button 130 is pressed or released, the sliding rib can slide in the guiding groove, so that the sliding of the sliding member 120 is smoother and more stable.

Of course, the sliding portion 123 may also be a sliding groove, and the guiding portion 1131 is a guiding rib adapted to the sliding groove, when the button 130 is pressed or released, the sliding groove can slide along the guiding rib, so as to improve stability and smoothness of the sliding member 120 during sliding.

Still further, referring to fig. 3, a plurality of sliding portions 123 and guiding portions 1131 may be provided, respectively, and the plurality of sliding portions 123 may be disposed at intervals along a direction perpendicular to the sliding direction of the sliding member 120, and each sliding portion 123 is slidably connected to one guiding portion 1131.

It is easily understood that by providing the plurality of guide portions 1131 and the plurality of sliding portions 123, the stability and smoothness of the sliding member 120 during sliding can be further improved.

In one embodiment, the elastic portion 122 is an elastic arm, one end of which is connected to one side of the slider 120, and the other end of which abuts against the cavity wall of the accommodating cavity 113.

In this embodiment, since the elastic arm can store and release elastic potential energy, when the button 130 is released, the elastic arm can apply elastic force to the slider 120 to drive the slider 120 to slide and reset, so as to limit the sensor to slide out of the insertion port 114, thus reducing the installation steps of the sensor, and being more convenient for medical staff to use.

With continued reference to fig. 3, further, the elastic arm includes a connecting section 1221 and a bending section 1222, one side of the slider 120 facing away from the button 130 is provided with a avoiding groove 125, the connecting section 1221 is fixed on a groove wall of the avoiding groove 125, one end of the bending section 1222 is connected with the connecting section 1221, and the other end of the bending section 1222 abuts against a cavity wall of the accommodating cavity 113.

It will be appreciated that by providing relief groove 125, relief groove 125 can accommodate at least a portion of curved segment 1222 when open cavity 121 is aligned with insertion port 114, thereby reducing the footprint of slider 120 and spring 122 and improving compactness.

Meanwhile, due to the avoidance groove 125, at least part of the bending section 1222 can be accommodated in the avoidance groove 125, so that the bending degree of the bending section 1222 is increased, and the elastic force is increased, so as to meet the elastic resetting requirement of the slider 120. In addition, the curved section 1222 has a curved surface curved in a direction approaching the relief groove 125, which further increases the elastic force.

In another embodiment, the elastic portion 122 is a cylindrical spring, and the cylindrical spring is connected between the sliding member 120 and the cavity wall of the accommodating cavity 113, for example, the cylindrical spring is fixed between the sliding member 120 and the cavity wall of the accommodating cavity 113, or is abutted between the sliding member 120 and the cavity wall of the accommodating cavity 113, so that the same resetting effect as that of the elastic arm can be achieved.

As shown in fig. 2, in one embodiment, a plugging rod 124 is disposed on a side of the sliding member 120 facing away from the elastic portion 122, and a button 130 is provided with a plugging hole adapted to the plugging rod 124, and the plugging rod 124 is in interference fit with the plugging hole.

In this embodiment, since the plug rod 124 and the plug hole are mutually matched, and the plug rod 124 and the plug hole can be in interference fit, when the button 130 is installed, the plug rod 124 can be inserted into the plug hole to quickly complete the installation of the button 130, so that the convenience in assembling and disassembling the button 130 is improved.

In another embodiment, a screw is disposed on a side of the sliding member 120 facing away from the elastic portion 122, and the button 130 is provided with a threaded hole, so that the screw is inserted into the threaded hole by screwing the button 130, and the button 130 is also convenient to mount and dismount from the sliding member 120.

With continued reference to fig. 2, in one embodiment, the body 110 includes a fixing bracket 116, a mounting base 111, and a protective cover 112, the mounting base 111 is connected to the fixing bracket 116, the fixing bracket 116 defines a limiting space 117, the protective cover 112 is connected to the mounting base 111 to define a receiving cavity 113, and the protective cover 112 is detachable.

Illustratively, the mounting base 111 may be provided with a threaded hole 1111, the protecting cover 112 may be provided with a mounting hole, and the assembling of the protecting cover 112 and the mounting base 111 may be achieved by threading a screw portion of a screw through the mounting hole and the threaded hole 1111. Of course, the protection cover 112 may be connected to the mounting base 111 by a locking or fastening method.

In this embodiment, the protective cover 112 can protect the sensor, and facilitate the assembly of the slider 120, the button 130 and the mounting base 111. By arranging the fixing support 116 with the limiting space 117, the body 110 is conveniently sleeved on the ultrasonic probe.

As shown in fig. 1 and 5, further, the fixing support 116 includes a U-shaped structure 1161 and an arc-shaped buckle 1162, and one end of the arc-shaped buckle 1162 is hinged to the U-shaped structure 1161 and can enclose the U-shaped structure 1161 to form a limiting space 117.

Thus, when the connection structure 100 is assembled, the ultrasonic probe is placed in the limit space 117, and then the arc-shaped buckle 1162 is rotationally buckled, so that the assembly of the connection structure 100 and the ultrasonic probe is completed.

Therefore, through the arrangement of the arc-shaped buckle 1162 and the U-shaped structure 1161, the quick assembly of the connecting structure 100 and the ultrasonic probe is facilitated, and the assembly efficiency is improved.

As shown in fig. 4 and fig. 5, in one embodiment, a limit rib 1141 is disposed at an edge of a side of the insertion port 114 away from the elastic portion 122, and the limit rib 1141 extends along a direction close to the sliding member 120, so that when the sliding member 120 is driven by the elastic portion 122 to reset, the limit rib 1141 can abut against a surface of the sensor, thereby limiting the sensor in the open cavity 121 and preventing the sensor from sliding out, and thus, by the arrangement of the limit rib 1141, stability of the sensor after installation is improved.

In one embodiment, the size of the insertion opening 114 is larger than the size of the open cavity 121 in the sliding direction of the slider 120, facilitating the medical staff to insert the sensor into the open cavity 121 through the insertion opening 114, thereby reducing the installation time of the sensor and improving the installation efficiency.
