Description

Technical Field

[0001] The present invention relates to the technical field of puncture devices, and particularly to a puncture rack and a puncture device. Background Art

[0002] Ultrasonic imaging devices can display the lesion area in a patient's body in real time. Under ultrasonic guidance, a puncture needle is guided to the target position in the human body to achieve cytological biopsy, histological biopsy, cyst aspiration and treatment, etc. Since the area displayed by the ultrasonic probe is usually a plane, in order to ensure the accurate puncture of the puncture needle, currently, a puncture rack is set on the ultrasonic probe, so that the puncture needle always remains on the ultrasonic plane, thereby enabling the puncture needle to always be displayed in the ultrasonic imaging device, and a doctor can adjust the puncturing position and depth of the puncture needle according to the image.

[0003] When using the puncture rack, it is necessary to first put a probe cover on the ultrasonic probe, and then fix the puncture rack on the ultrasonic probe with the probe cover. However, the materials and thicknesses of different probe covers are different, which will have a great impact on the fixation of the puncture rack. In order to overcome this technical problem, most current puncture racks choose to fix by clamping the outer periphery of the ultrasonic probe. After selecting an appropriate clamping force, it can fit most probe covers.

For the sake of simplicity, in the description of each implementation manner of the present application, the same or similar reference numerals are used for the same or similar device / method steps.

[0033] It should be noted that, without conflict, the implementation manners and features in the implementation manners of the present application can be combined with each other.

[0034] Figure 1 It is a schematic structural diagram of the puncture frame provided by the embodiment of the present invention; Figure 2 It is an exploded view of the puncture frame provided by the embodiment of the present invention; Figure 3 It is a schematic structural diagram of the back side of the frame body in the puncture frame provided by the embodiment of the present invention; Figure 4It is a schematic structural diagram of the locking pressure block in the puncture rack provided by the embodiment of the present invention; Figure 5 It is a schematic structural diagram of the back side of the puncture rack provided by the embodiment of the present invention. As Figures 1 to 5 shown, the puncture rack includes a rack body and a locking pressure block 21, and the locking pressure block 21 is detachably connected to the rack body; wherein, when the locking pressure block 21 is connected to the rack body, a card slot for clamping with the ultrasonic probe 4 is formed between the locking pressure block 21 and the rack body.

[0035] As Figure 1 and Figure 2 shown, the rack body includes a main body 1, a locking device 2 and a needle rack 3, and the main body 1 and the needle rack 3 are detachably connected. Among them, multi-angle puncture channels are provided on the needle rack 3, and a rack body with multi-angles is formed after the needle rack 3 is connected to the main body 1. When the rack body is connected to the ultrasonic probe 4, the back side of the main body 1, that is, the side away from the needle rack 3, is connected to the ultrasonic probe 4 through the locking device 2.

[0036] The puncture rack provided by the embodiment of the present invention can ensure the stable connection between the rack body and the ultrasonic probe 4, and at the same time, can optimize the structure of the locking device 2 for connecting with the ultrasonic probe 4 and the installation steps, which will be specifically described below.

[0037] As Figure 4 and Figure 5 shown, the locking pressure block 21 is rod-shaped, its first end is rotatably connected to the rack body, and its second end is detachably connected to the rack body, such as clamping; a card slot for clamping with the ultrasonic probe 4 is formed between the first side wall of the locking pressure block 21 and the outer wall of the rack body. With this structure, the locking pressure block 21 can take the rotating shaft 13 as the rotation point. When the second end of the locking pressure block 21 is in the open state, the puncture rack can be separated from the ultrasonic probe 4, and when it is in the locked state, the puncture rack and the ultrasonic probe 4 are firmly connected.

[0038] As Figures 3 to 5 shown, the figure shows the specific structures of the rotational connection and the clamping connection, that is, a rotating shaft 13 and a protruding lock block 14 are provided on the rack body; a rotating groove 22 is provided at the first end of the locking pressure block 21, and a lock hook 23 is provided at the second end; the rotating groove 22 is rotatably connected to the rotating shaft 13, and the lock hook 23 is clamped with the lock block 14. Among them, the connection or separation of the lock hook 23 and the lock block 14 realizes the detachable connection between the locking pressure block 21 and the rack body. As Figure 3 shown, two oppositely arranged vertical plates 15 are provided on the rack body, and both ends of the rotating shaft 13 are fixedly connected to the opposite sides of the two vertical plates 15; as Figure 4As shown, the first end of the locking pressing block 21 is provided with a bent portion, and the angle between the bent portion and the locking pressing block 21 is less than 180 degrees. The rotating groove 22 is arranged on the first side wall of the bent portion, and a limiting block 25 for abutting against the vertical plate 15 is arranged on the second side wall of the bent portion. The first end of the locking pressing block 21 rotates freely around the rotating shaft 13. By arranging the structure of the vertical plate 15 and the limiting block 25, when the locking pressing block 21 rotates to a certain angle, the limiting block 25 abuts against the vertical plate 15, so that the locking pressing block 21 cannot continue to rotate, thus playing a limiting role. Generally, the limiting angle is 90°. Through this limiting structure, the unrestricted free rotation of the locking pressing block 21 can be avoided, and the probability of their separation and detachment can be reduced.

[0039] As Figure 4 shown, the second end of the locking pressing block 21 is provided with a U-shaped curved rod 24, and the first free end of the curved rod 24 is connected to the second end of the locking pressing block 21; the locking hook 23 includes a support rod portion and a locking portion. The first end of the support rod portion is connected to the locking portion, and the second end is connected to the second free end of the curved rod 24. The U-shaped structure of the curved rod 24 can increase the elastic deformation amount of the second end of the locking pressing block 21, making it easier to complete the locking or unlocking operation of the locking hook 23.

[0040] The puncture rack provided by the embodiment of the present invention further includes a handle portion 26, and the handle portion 26 is fixedly connected to the second end of the support rod portion and the second free end of the curved rod 24. As Figure 4 and Figure 5 shown, when the locking pressing block 21 is in use, manually pressing the handle portion 26 can realize the position movement of the locking hook 23, and then complete the locking or unlocking operation of the locking hook 23. The structure of the handle portion 26 can further facilitate the detachable operation of the locking pressing block 21.

[0041] As Figure 3 shown, a positioning convex rib 12 is arranged on the outer wall of the frame body, and the first side wall of the locking pressing block 21 fits with the positioning convex rib 12 to form a clamping groove. When the locking pressing block 21 is connected to the outer wall of the frame body (i.e., connected to the back side of the main body 1), a clamping groove needs to be formed between the two. Therefore, there needs to be a certain interval between the locking pressing block 21 and the outer wall of the frame body. In this embodiment, the positioning convex rib 12 is arranged on the outer wall of the frame body, and the positioning convex rib 12 is in an arched structure. When the locking pressing block 21 fits with the frame body, a part of the locking pressing block 21 fits on the positioning convex rib 12, and the other part keeps a certain interval from the frame body, thus forming a clamping groove.

[0042] As Figure 3 and Figure 5As shown, the first end of the positioning rib 12 abuts against the side wall where the first free end of the curved rod 24 is located. The positioning rib 12 has a certain length. When the locking pressing block 21 fits with the frame body, the side wall of the curved rod 24 close to the positioning rib 12 just engages with it. The first end of the locking pressing block 21 is rotatably connected to the frame body, and the second end is clamped on the positioning rib 12 through the curved rod 24. The locking pressing block 21 is stably connected to the frame body, thereby avoiding random shaking of the locking pressing block 21 after locking and improving the locking stability.

As Figures 6 to 8 shown, the puncture device includes an ultrasonic probe 4 and the above-mentioned puncture frame; the ultrasonic probe 4 includes a groove 41 and a positioning plate 42. The frame body is clamped with the groove 41, and the positioning plate 42 is inserted into the card slot. When the ultrasonic probe 4 is connected to the puncture frame, the locking pressing block 21 is in an open state. Then, the main body 1 is clamped in the groove 41, and the positioning plate 42 is inserted into the arc portion of the positioning rib 12. Then, the locking pressing block 21 is locked. At this time, the positioning plate 42 is in the card slot and is pressed by the locking pressing block 21, and the puncture frame and the ultrasonic probe 4 are connected.

[0044] As Figure 3 and Figure 5 shown, a positioning block 11 is further provided on the frame body, and a positioning groove (not shown) for engaging with the positioning block 11 is provided on the ultrasonic probe 4. When the main body 1 is connected to the groove 41, the positioning block 11 is engaged in the positioning groove, making the connection between the main body 1 and the ultrasonic probe 4 more stable.

[0045] According to the embodiment provided by the present invention, a locking pressing block 21 is provided on the frame body. The locking pressing block 21 can form a card slot with the frame body, and the connection between the frame body and the ultrasonic probe 4 can be realized by using this card slot. The structure of the locking pressing block 21 in the frame body is simple and the operation is convenient, which is beneficial to the quick and stable connection between the puncture frame and the ultrasonic probe 4.
