Technical Field

[0001] The present invention relates to the technical field of puncture equipment, and in particular to a puncture frame and a puncture equipment. Background Art

[0002] Ultrasound imaging equipment can display the lesion area in the patient's body in real time, and guide the puncture needle to the target position of the human body under the guidance of the ultrasound imaging equipment to achieve cytological biopsy, histological biopsy, cyst aspiration and treatment, etc. Since the area displayed by the ultrasound probe is usually a plane, in order to ensure the accurate puncture of the puncture needle, a bracket is currently set on the ultrasound probe to keep the puncture needle on the ultrasound plane at all times. In this way, the puncture needle can always be displayed in the ultrasound imaging equipment, so that the doctor can adjust the insertion position and depth of the puncture needle according to the image.

[0003] The puncture frame includes a fixing frame for fixing the ultrasonic probe and a needle guide device for connecting with the fixing frame. The needle guide device is used for guiding the puncture needle to always keep the puncture needle in the ultrasonic image plane.

[0004] There are two needle insertion modes in the existing puncture frame. One is a closed structure, in which a hole is set on the puncture frame, and the puncture needle passes through the hole to enter the puncture frame; the other is an open structure, that is, a semi-open needle slot is set, and the puncture needle can enter from the side through the opening of the slot. The closed structure has good stability in use, but it is not easy to perform the insertion operation and is not conducive to fine-tuning the puncture position; the open structure is easy to put the needle into the needle slot and can easily fine-tune the direction of the needle, but due to its large degree of freedom, its stability is not as good as the closed structure, and the puncture needle is easy to deviate from the ultrasound image plane.

[0026] The present application is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present application. For the sake of simplicity, in the description of each implementation of the present application, the same or similar reference numerals are used for the same or similar device / method steps.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.

[0028] Figure 1 It is a schematic structural diagram of a puncture frame provided in an embodiment of the present invention when a closed guide channel is formed; Figure 2 This is a front view of the puncture frame provided in an embodiment of the present invention when forming a closed guide channel; Figure 3 It is a schematic structural diagram of a puncture frame provided in an embodiment of the present invention when an open guide channel is formed; Figure 4 1 is a front view of the puncture frame provided in the embodiment of the present invention when forming an open guide channel. Figures 1 to 4As shown, in the embodiment of the present invention, the puncture frame includes a clamp 1 and a needle guide device arranged on the clamp 1; the needle guide device includes a guide groove 3, the guide groove 3 includes a bottom plate 8, a first side wall 9 and a second side wall 4, and the notch of the guide groove 3 is provided with a locking block 5, and the locking block 5 can move between the first position and the second position; the locking block 5 rotates to the first position, the locking block 5 blocks the notch and forms a closed guide channel with the guide groove 3; the locking block 5 rotates to the second position, the locking block 5 moves out of the notch, so that the guide groove 3 forms an open guide channel. When the puncture frame is used, the clamp 1 is used to connect the ultrasonic probe, and then, according to the actual use requirements, the closed guide channel or the open guide channel of the puncture needle 7 is selected, and the switching of the two guide modes can be realized by turning the position of the locking block 5.

[0029] The first end of the locking block 5 is rotatably connected to the top end of the first side wall 9. When the locking block 5 is in the first position, the second end of the locking block 5 fits the inner surface of the second side wall 4. Specifically: the width of the locking block 5 is slightly larger than the width of the guide groove 3. When the locking block 5 moves from the second position to the first position, when the second end of the locking block 5 moves to the specified position, generally when the locking block 5 is perpendicular to the first side wall 9 and the second side wall 4, since the width of the locking block 5 is slightly larger, the second end of the locking block 5 applies a certain force to the second side wall 4, causing the second side wall 4 to deform away from the first side wall 9; the locking block 5 is continuously moved, the locking block 5 is inclined relative to the second side wall 4, the abutting force of the locking block 5 on the second side wall 4 disappears, and the second side wall 4 is deformed and reset. Finally, the locking block 5 moves to the first position, and its second end fits the inner surface of the second side wall 4. This structural manner not only facilitates the movement of the locking block 5 , but also enables the locking block 5 to be limited between the first side wall 9 and the second side wall 4 when reaching the first position, thereby making the closed guide channel have better stability.

[0030] In the embodiment of the present invention, the locking block 5 uses the first end as the rotation point to control the second end to rotate. In the closed guide channel state, the second end of the locking block 5 fits the inner surface of the second side wall 4. At this time, the locking block 5 and the guide groove 3 form a closed channel structure, that is, a closed guide channel. The puncture needle has good stability in the closed guide channel. However, the puncture needle cannot be separated from the closed guide channel during the puncture process, or the separation operation is complicated. Similarly, the first end of the locking block 5 is used as the rotation point, and the needle body of the locking block 5 is moved out of the guide groove 3, so that the notch of the guide groove 3 has no blocking structure. In this state, the guide groove 3 forms an open guide channel, and the side of the open guide channel is provided with an opening (i.e., a notch). During the puncture process, the puncture needle can be separated from the open guide channel through the opening, and the puncture needle separation operation is simple and quick.

[0031] In the embodiment of the present invention, the locking block 5 and the first side wall 9 are integrally formed, and the first end of the locking block 5 is connected to the top of the first side wall 9 through a bendable thin wall 51; the locking block 5 is moved between the first position and the second position by bending the thin wall 51. The locking block 5 and the guide groove 3 are manufactured by an integral injection molding process, which can optimize the product structure and reduce the manufacturing cost. In addition, the bending structure formed by the thin wall 51 facilitates the movement / rotation operation of the locking block 5. In addition, by providing a handle 6 on the locking block 5, it is further convenient to apply operation to the locking block 5.

[0032] like Figures 1 to 4 As shown, the height of the second side wall 4 is greater than that of the first side wall 9, and a bent portion 61 is provided on the handle 6; when the locking block 5 is in the first position, the second end of the locking block 5 and the bent portion 61 are both in contact with the inner surface of the second side wall 4. The second side wall 4 has a portion extending horizontally outward relative to the first side wall 9, so that the height of the second side wall 4 is higher than that of the first side wall 9, and the extended portion can abut against the bent portion 61 of the handle 6, which limits the movement of the handle 6 and the locking block 5, and prevents the locking block 5 from moving beyond the second position.

[0033] like Figure 1 and Figure 3 As shown, the needle guide device is connected to the clamp 1 through a rotating structure. The rotating structure can connect and fix the needle guide device and the clamp 1, and can adjust the angle between the needle guide device and the puncture plane. The specific embodiment provided by the present invention is: the rotating structure includes a first connecting seat 11, a second connecting seat 31 and a rotating shaft 2; the first connecting seat 11 is arranged on the outer wall of the clamp 1, the second connecting seat 31 is arranged on the guide groove 3, and the rotating shaft 2 is used to pass through the first connecting seat 11 and the second connecting seat 31 in sequence to realize the rotation connection between the two.

[0034] like Figures 1 to 4 As shown, the second connecting seat 31 is connected to the side of the bottom plate 8 away from the first side wall 9 and the second side wall 4, and the notch of the guide groove 3 is set in the direction away from the clamp 1. The notch of the guide groove 3 is located at the farthest distance relative to the clamp 1. During the puncture operation, the influence of the clamp 1, the ultrasonic probe and other devices on the puncture operation can be reduced. In addition, in the embodiment of the present invention, the needle insertion direction of the guide groove 3 is the same as the axial direction of the clamp 1, and the guide groove 3 has a certain depth along the needle insertion direction. Therefore, the entrance of the guide groove 3 is at a certain distance from the human skin. In this way, the interference of the human body on the entrance of the guide groove 3 can be reduced. For example, obesity causes excess skin and flesh tissue to bury the entrance of the guide groove 3.

[0035] In the embodiment of the present invention, the guide groove 3 may be in the shape of a square groove, a circular groove or any other shape, and may be used for biopsy needles, thyroid needles, PTC needles, particle implantation needles and other needles used for biopsy flow, aspiration and injection.

[0036] The embodiment of the present invention also provides a puncture device, which includes an ultrasonic probe and the above-mentioned puncture frame; the clamp is sleeved on the outer wall of the ultrasonic probe. The puncture device is provided with a position-variable locking block at the notch of the guide groove, and a closed guide channel or an open guide channel can be formed by moving the locking block. When performing a puncture operation, medical staff can select an appropriate puncture needle guiding method according to actual needs, and the product has high convenience and versatility.

[0037] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
