Description

Technical Field

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

[0002] Ultrasound interventional surgery is a new technology developed based on ultrasound imaging. During the procedure, an ultrasound probe puncture stent is installed on the ultrasound probe. Then, under the precise guidance of the ultrasound probe puncture stent, the puncture needle can reach the lesion directly. It can perform surgical procedures such as aspiration, medication, and catheterization, as well as precise treatments such as microwave, radiofrequency, and laser energy. Unlike traditional surgical procedures, ultrasound interventional surgery does not require an incision, requiring only a fine needle puncture. Patients experience minimal pain and do not need hospitalization. It is relatively safe, simple to perform, and has high practical value.

[0003] Magnetic navigation sensors are required during magnetic navigation puncture surgery. Therefore, three types of brackets, namely, an ultrasound probe frame, a needle structure, and a magnetic navigation magnetic sensor bracket, need to be used simultaneously during the puncture surgery.

[0029] The magnetic sensor bracket and puncture bracket provided in the embodiment of the present invention have a simple structure, are easy to produce and manufacture, and facilitate quick disassembly and assembly of the sensor. The magnetic sensor bracket is installed on the puncture bracket, reducing the space occupied by the magnetic sensor bracket and the space required for installation. At the same time, both the sensor bracket and the puncture bracket are disposable, which can reduce the risk of infection. A detailed explanation is given below.

[0030] Figure 1 This is a schematic diagram of the structure of the magnetic sensor bracket provided by the embodiment of the present invention. Figure 1 As shown, the magnetic sensor holder 2 includes a sleeve 21, the first axial end of which serves as an insertion port. A snap-fit ​​structure 3 for connecting to the puncture holder is provided on the outer wall of the sleeve 21. The magnetic sensor holder 2 is connected to the puncture holder via the snap-fit ​​structure. The sleeve 21 is used to connect to the magnetic sensor, and the magnetic sensor holder 2 does not require intraoperative installation.

[0031] Figure 2 A cross-sectional view of a magnetic sensor bracket provided in an embodiment of the present invention. Figure 1 and Figure 2 As shown, the side wall of the sleeve 21 is provided with an opening 23, which penetrates the side wall of the sleeve along the axis of the sleeve. When the sleeve 21 is connected to the sensor, the sensor enters the sleeve 21 from the insertion port, causing the opening 23 to expand and the sleeve 21 to deform. The sensor is then tightened by the resilience of the sleeve 21. In an embodiment of the present invention, the inner diameter of the sleeve 21 is the same as or slightly smaller than the outer diameter of the sensor to which it is adapted. When the sensor is connected to the sleeve 21, the sensor is inserted into the sleeve 21 from the insertion port under the action of an external force. During the insertion process, due to the opening 23 on the wall of the sleeve 21, the opening 23 expands under the pressure of the sensor, thereby causing the sleeve 21 to deform. Due to the resilience of the sleeve 21, the sleeve 21 tightens the sensor inside, achieving the purpose of fixation. When removing the sensor, the sensor can be pulled out of the sleeve 21 with force. The magnetic sensor bracket 2 provided in the embodiment of the present invention has a simple structure and a certain elasticity, so that the sensor can be installed stably and the sensor can be easily and quickly assembled and disassembled.

[0032] like Figure 1 and Figure 2As shown, the magnetic sensor bracket 2 also includes a limit baffle 22, which is provided at the second port of the sleeve 21 and blocks the second port; the sleeve 21 is in the shape of a rectangular parallelepiped and includes four side walls, namely a first side wall, a second side wall, a third side wall and a fourth side wall; an opening 23 is provided on the first side wall of the sleeve, and a clamping structure 3 is provided on the outer wall of the second side wall; an extension portion 24 is provided at one end of the second side wall located at the second port of the sleeve; the extension portion 24 extends along the axial direction of the sleeve 21, and the limit baffle 22 is vertically connected to the extension portion 24. The limit baffle 22 in the sleeve 21 can prevent the sensor from passing through the sleeve 21. During the sensor installation operation, when the top of the sensor abuts against the limit baffle 22, it means that the sensor is installed in place. The limit baffle 22 not only serves as a limit, but also serves as a reminder that the installation is complete, which facilitates the rapid assembly of the sensor. Preferably, a gap is provided between the limit baffle 22 and the second end of the sleeve 21, which exposes the end portion of the sensor, that is, the sleeve 21 does not half-wrap the end of the sensor, thereby reducing interference with the signal.

[0033] Continue to refer Figure 1 and Figure 2 As shown in the figure, ridges 25 are provided on the inner walls of the second, third and fourth side walls of the sleeve 21 along the axial direction of the sleeve 21. When the sensor is installed in the sleeve 21, the outer wall of the sensor abuts against the top of the ridges 25. The ridges 25 structure can reduce the contact area between the inner wall of the sleeve 21 and the sensor, thereby reducing friction and facilitating the sensor insertion operation. In addition, the outer wall of the sensor is not entirely in contact with the inner wall of the sleeve 21, which can reduce interference with the signal.

[0034] Figure 3 A cross-sectional view of a raised block in a frame provided in an embodiment of the present invention; Figure 4 This is a cross-sectional view of the extension plate in the frame provided by the embodiment of the present invention. Figure 3 and Figure 4 As shown, in the embodiment of the present invention, the frame of the puncture bracket includes a clamp 1, and the magnetic sensor bracket 2 and the clamp 1 of the frame can be an integrated structure or a split structure. Among them, the integrated structure does not require assembly operation and is more convenient to use, while the split structure can improve the versatility of the magnetic sensor bracket 2 and the frame, and different models of magnetic sensor brackets 2 and frames can be combined to adapt to different models of ultrasound probes and sensors.

[0035] like Figure 3 and Figure 4In the structure shown, the frame and the magnetic sensor bracket 2 are separate structures, and the two are connected by a clamping structure 3; the clamping structure 3 includes a first clamping portion and a second clamping portion, the first clamping portion is connected to the outer wall of the sleeve, and the second clamping portion is connected to the outer wall of the clamp 1; the first clamping portion and the second clamping portion are clamped, thereby realizing a detachable connection between the magnetic sensor bracket 2 and the clamp 1.

[0036] like Figure 3 and Figure 4 As shown, in an embodiment of the present invention, the first clamping portion includes a protruding block 31, one end of the protruding block 31 is fixedly connected to the outer wall of the sleeve, and at least one extension plate 32 is provided at the end of the protruding block 31 away from the sleeve, and the extension plate 32 has a limited angle with the outer wall of the protruding block 31; the second clamping portion includes a slot 34, the slot 34 includes a panel 341, and a strip notch 342 is provided on the panel 341, and one end of the strip notch 342 is located at the notch of the slot 34; when the magnetic sensor bracket 2 and the clamp 1 are connected, the protruding block 31 is inserted into the strip notch 342, and the extension plate 32 is inserted into the slot 34.

[0037] In the clamp 1 and the magnetic sensor bracket 2, the first clamping portion and the second clamping portion can be designed as standard components, that is, any model of compatible clamp 1 and magnetic sensor bracket 2 includes the same first clamping portion and second clamping portion. Therefore, any model of clamp 1 can be connected to any model of magnetic sensor bracket 2, thereby improving the versatility of the clamp 1 and sensor with a split structure.

[0038] In the embodiment of the present invention, a fool-proof structure is provided in the clamping structure 3 , which can prevent the magnetic sensor bracket 2 from being installed in the wrong direction and facilitates the rapid assembly of the clamping structure 3 . Figure 5 This is a schematic diagram of the structure of the clamping structure in the frame provided by the embodiment of the present invention. Figures 3 to 5 As shown, this structure is one type of foolproof structure. Two extension plates 32 are provided on the raised block 31. One of the extension plates 32 has a cut surface 321 on the end away from the raised block 31. A retaining wall 343 is provided within the slot 34 to mate with the cut surface 321. When the magnetic sensor bracket 2 and the clamp 1 are connected, the extension plate 32 is inserted into the slot 34, and the cut surface 321 mates with the retaining wall 343. When the clamping structure 3 is connected, the extension plate 32 can only be smoothly removed and inserted into the slot 34 when the retaining wall 343 is aligned with the cut surface 321, thus preventing the magnetic sensor bracket 2 from being installed in the wrong direction.

[0039] In the embodiment of the present invention, the foolproof structure can also adopt another structural form. Figure 6 This is a schematic diagram of the structure of the clamping structure in the frame provided by the embodiment of the present invention. Figure 3 、 Figure 4 and Figure 6As shown, the first engaging portion includes two protruding blocks 31, each of which is provided with an extension plate 32, namely a first extension plate 322 and a second extension plate 323. The first extension plate 322 and the second extension plate 323 have different widths. The second engaging portion includes two slots 34, namely a first slot 344 and a second slot 345. The width of the first slot 344 is the same as the width of the first extension plate 322, and the width of the second slot 345 is the same as the width of the second extension plate 323. When the magnetic sensor bracket 2 and the clamp 1 are connected, the first extension plate 322 is inserted into the first slot 344, and the second extension plate 323 is inserted into the second slot 345. In this foolproof structure, the extension plate 32 can only be smoothly inserted into the slot 34 if the widths match.

[0040] Figure 7 This is a cross-sectional view of the groove in the frame provided by the embodiment of the present invention. Figure 3 、 Figure 4 and Figure 7 As shown, the side of the strip-shaped notch 342 facing the raised block 31 is provided with an inwardly concave groove 346, and the side of the raised block 31 opposite the groove 346 is provided with a raised bump 311. When the magnetic sensor bracket 2 and the clamp 1 are connected, the bump 311 is engaged with the groove 346. The connection between the bump 311 and the groove 346 acts as a limiter. In the absence of external force, the bump 311 and the groove 346 always remain engaged, thereby ensuring a stable connection between the extension plate 32 and the slot 34.

[0041] This embodiment also provides a puncture stent. Figure 8 Schematic diagram of the structure of the puncture stent provided by the embodiment of the present invention. Figure 8 As shown, the puncture bracket includes a frame body, which includes a clamp 1, a needle structure 4 and a magnetic sensor bracket 2. The puncture bracket is disposable and can simultaneously connect an ultrasound probe, a magnetic navigation sensor (or other sensor), and a puncture needle.

[0042] The magnetic sensor bracket 2 is connected to the frame. When in use, there is no need to reconnect the magnetic sensor bracket 2, thus saving installation time and eliminating the need to reserve space for installation. The magnetic sensor bracket 2 and the frame are disposable, eliminating the need for a dedicated magnetic sensor bracket 2, reducing costs. The need for cleaning also reduces the risk of infection, making the use of the magnetic sensor bracket 2 safer and more reliable.

[0043] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
