Description

Technical Field

[0001] This invention belongs to the field of ultrasonic equipment technology, and relates to an adjustable puncture angle puncture frame structure and ultrasonic puncture equipment. Background Technology

[0002] Ultrasound-guided interventional diagnosis and treatment require a puncture frame for the ultrasound probe. Typically, the puncture needle is secured using the puncture frame, and the puncture is performed under the guidance of a medical ultrasound instrument. Compared to manual puncture, puncture guided by a puncture frame allows the needle to travel along a pre-set guideline on the ultrasound device, and the procedure is monitored on an ultrasound monitor, enabling precise attainment of the puncture target.

[0003] Traditional ultrasound probe puncture frames typically have a fixed puncture angle, allowing only punctures at specific angles. To provide multiple puncture angles, puncture frames with multiple puncture needle slots have recently appeared on the market, but they still cannot meet the diverse needs of clinical practice. Summary of the Invention

[0013] The support base opposite to the limiting post has multiple limiting grooves on one side surface;

[0014] The number of the plurality of limiting grooves is the same as the number of the plurality of puncture guide channels, so that when the puncture needle seat rotates, the limiting post cooperates with different limiting grooves to limit the puncture angle of the corresponding puncture guide channel.

[0015] Furthermore, one of the plurality of limiting grooves is constructed at the bottom of the rotating shaft movable groove, and the limiting groove is a U-shaped groove.

[0016] Furthermore, the first surface of the puncture frame is provided with a relief groove that allows the support to partially disengage from the first surface.

[0017] Furthermore, the plurality of puncture guide channels are staggered from each other, and the included angle formed by the longitudinal axes of any two of the puncture guide channels is the same.

[0018] Furthermore, the adjusting base is integrally formed with the puncture frame.

[0019] Furthermore, each of the puncture guidance channels includes two resilient tubes that define an elongated channel to accommodate the puncture needle;

[0020] The upper ends of the two segments form an opening, and the lower ends are connected;

[0021] A guide funnel is installed at the entrance end of the puncture guidance channel.

[0022] Furthermore, the first surface is provided with locking feet at both ends along its length.

[0035] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0036] This invention relates to an ultrasonic puncture device, comprising an ultrasonic probe 20 and a puncture frame structure body 10 detachably connected to the head 21 of the ultrasonic probe 20. Guided by the puncture frame structure body 10, a puncture needle is inserted into a target site within the patient's body detected by the ultrasonic probe 20.

[0037] Figures 1-4 The diagram shows a schematic of an adjustable puncture angle puncture frame structure. The adjustable puncture angle puncture frame structure includes a puncture frame 11 and a puncture needle seat 12 connected to the puncture frame 11 and capable of rotational adjustment. The puncture frame 11 is detachably connected to the ultrasound probe 20. During clinical use, the puncture needle seat 12 can be rotated relative to the puncture frame 11 as needed to adjust the corresponding puncture angle.

[0038] The ultrasonic puncture device employs a puncture frame 11 with at least two puncture guide channels 121, making it suitable for use with at least two types of puncture needles, thus improving the adaptability of the puncture device. For example... Figures 7-10 As shown, the present invention provides three puncture guidance channels 121, and the distances from the puncture points M, N, and P of the three puncture guidance channels 121 to the probe of the ultrasonic puncture device are 2mm, 1.5mm, and 1mm, respectively.

[0039] like Figure 5 As shown, the puncture frame 11 includes a first surface 117 having a first end 115 and a second end 116. The first surface 117 acts as a support. The puncture frame 11 is configured to be connected to the ultrasonic probe of the ultrasonic puncture device. The puncture frame 11 is generally made of plastic injection molding.

[0040] An adjustment base is provided on the first surface 117 of the puncture frame 11. The adjustment base can be integrally formed with the puncture frame 11, or it can be separately set and installed on the puncture frame 11.

[0041] The puncture needle seat 12 is rotatably mounted on the adjustment base. The puncture needle seat 12 is provided with multiple puncture guide channels 121. A limiting component is provided between the adjustment base and the puncture needle seat 12 to limit the puncture angle of each puncture guide channel 121 when it is in the working state.

[0042] Furthermore, in order to achieve the rotational adjustment of the puncture needle seat 12 on the adjusting base, the two side surfaces of the puncture needle seat 12 are provided with rotating shafts 123, and the adjusting base is provided with two opposing support seats 111. At the corresponding positions of the two support seats 111, there are rotating shaft movable grooves 114 that match the rotating shafts 123.

[0043] like Figure 6 As shown, the puncture needle hub 12 includes an adjustment end 124 and a needle hub end 125. A raised rib is provided on the upper surface of the adjustment end 124 to prevent slippage during rotational adjustment of the puncture needle hub 12. Multiple puncture guide channels 121 are constructed on the needle hub end 125, with an included angle between the longitudinal axes of each puncture guide channel 121. In use, according to clinical needs, a puncture needle is placed in the corresponding puncture guide channel 121, and the rotation of the puncture needle hub 12 is adjusted via the adjustment end 124 to adjust the puncture needle to a suitable puncture angle.

[0044] The puncture frame 11 includes a support base 111 connected to the first surface 117. The rotating shafts 123 respectively provided on both sides of the puncture needle seat 12 are limited in the rotating shaft movable grooves 114 on the support base 111 to realize the rotation adjustment of the puncture needle seat 12.

[0045] Furthermore, the limiting component includes a limiting post 122 disposed on at least one side surface of the puncture needle seat 12, and a plurality of limiting grooves disposed on one side surface of the support seat 111 opposite to the limiting post 122; wherein the number of the plurality of limiting grooves is the same as the number of the plurality of puncture guide channels 121, so that when the puncture needle seat 12 rotates, the limiting post 122 cooperates with different limiting grooves to limit the puncture angle of the corresponding puncture guide channel 121.

[0046] One of the multiple limiting grooves is located at the bottom of the rotating shaft movable groove 114, and this limiting groove is a U-shaped groove 118.

[0047] like Figure 4 , 5 As shown, the multiple limiting grooves also include two elastic grooves 119 disposed on both sides of the U-shaped groove 118. The upper part of the elastic groove 119 cooperates with the limiting post 122 to form an adjustment and positioning for the puncture angle.

[0048] The first surface 117 of the puncture frame 11 is provided with a relief groove that allows the support seat 111 to partially disengage from the first surface 117, thereby increasing the mechanical elasticity of the support seat 111.

[0049] Multiple puncture guide channels 121 are arranged in a staggered manner, and the included angle formed by the longitudinal axes of any two puncture guide channels 121 is the same.

[0050] Understandably, each puncture guide channel 121 includes two elastic tubes that define a narrow channel to accommodate the puncture needle; the upper ends of the two tubes form openings to facilitate the removal of the puncture needle, and the lower ends are connected; a guide funnel is provided at the entrance end of the puncture guide channel 121 to guide the puncture needle into the puncture guide channel 121.

[0051] Furthermore, in order to achieve a reliable connection between the puncture guide device 10 and the head 21 of the ultrasound probe 20, the first surface 117 is provided with locking feet 113 at both ends along the length direction. The locking feet 113 can be used to lock the puncture frame 11 and the ultrasound probe 20, which facilitates installation and disassembly.

[0052] In order to facilitate the quick placement of the rotating shaft 123 into the rotating shaft movable groove 114 when the puncture needle seat 12 is connected to the puncture frame 11, a guide port 112 is provided at the upper end of the U-shaped groove 118. The guide port 112 is a flared shape with a larger outer end and a smaller inner end.

[0053] Understandably, in order to facilitate the rotation and adjustment of the puncture needle seat 12, the two sides of the puncture needle seat 12 are designed in an arc shape, which can effectively ensure that there is no jamming during rotation.

[0054] When using the puncture frame structure body 10, it is secured to the ultrasound probe 20 via the locking feet 113. The doctor uses the ultrasound probe 20 to locate the patient's target site and selects a suitable puncture guide channel 121 based on the distance of the target site from the body surface. Then, the doctor inserts the puncture needle into the guide funnel of the puncture guide channel 121. The two tubes of the puncture guide channel 121 expand to accommodate the puncture needle. Depending on the specific situation, the puncture needle seat 12 is rotated and adjusted to a suitable angle. Guided by the puncture guide channel 121, the puncture needle reaches the patient's target site, completing the puncture procedure.
