Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an ultrasonic puncture fixation device and its puncture-guided ultrasonic system. Background Technology

[0002] Pathological puncture is a commonly used interventional diagnostic and treatment method in clinical practice. In the past, during interventional procedures, operators could choose to perform puncture directly without image assistance or with CT or MR imaging assistance. However, the above methods are prone to various puncture accidents and increase the difficulty of puncture operation because the operator cannot observe the relative position of the needle and the target area in real time during the puncture process.

[0003] Therefore, ultrasound, which enables real-time imaging, has been gradually adopted in clinical practice for assisted puncture. By observing the ultrasound images during the procedure, doctors can adjust the needle path in real time, effectively reducing puncture accidents and improving the success rate. However, current ultrasound equipment has certain limitations. Because it relies on the operator's constant adjustments, the ultrasound probe must be held in one hand, while other operations are performed with the other. When procedures requiring both hands are needed, an assistant is required, significantly limiting clinical efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems and provide an ultrasonic puncture fixation device and its puncture-guided ultrasound system. The ultrasonic probe and puncture needle hub can be integrated into the ultrasonic puncture fixation device and then positioned on the skin of the operating area through a skin adhesion mechanism.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1

[0042] This embodiment provides an ultrasonic puncture fixation device, such as... Figures 1 to 16 As shown, the device includes a probe mounting base 11 for mounting an ultrasound probe 2. The probe mounting base 11 includes a detection end that faces the skin of the operating area during use. The detection end has a detection port 16, through which the ultrasound probe 2, mounted on the probe mounting base 11, can be exposed to emit ultrasound waves into the operating area. The probe mounting base 11 includes a skin adhesion mechanism and a puncture needle holder mounting mechanism. The skin adhesion mechanism is used to adhere to the skin to fix the probe mounting base 11 to the operating area, and the puncture needle holder mounting mechanism is used to mount a puncture needle holder 4.

[0043] The usage method is as follows:

[0044] S1. Apply an appropriate amount of sterile coupling agent to the ultrasonic probe 2, and wrap the probe with a disposable sterile probe protective sleeve, and tighten the disposable sterile probe protective sleeve.

[0045] S2. Insert the packaged ultrasound probe 2 into the puncture frame;

[0046] S3. Align the detection port 16 of the probe mounting base 11 with the skin of the operating area, start the ultrasound probe 2, and move the probe mounting base 11 for ultrasound positioning before puncture.

[0047] S4. After determining the puncture location, install a disposable puncture needle holder 4 at a suitable angle, hold the probe mounting base 11, and attach the skin adhesion mechanism to the skin to fix the probe mounting base 11 and the ultrasound probe 2.

[0048] S5. The puncture needle 5 is inserted through the guide hole 43 of the puncture needle seat 4.

[0049] S6. Operation complete. Withdraw the puncture needle 5 and apply local pressure with a cotton swab.

[0050] S7. After applying pressure to stop the bleeding according to the standard procedure, remove the skin adhesive device, remove the probe mounting base 11, clean the operating area, and apply appropriate bandaging and covering.

[0051] S8. Remove the ultrasound probe 2 and the puncture needle seat 4. After removing the protective cover of the ultrasound probe 2, the assistant cleans the ultrasound probe 2 to prepare for the next interventional procedure.

[0052] The specific operating procedures and order of the above usage methods are for reference only and are not required to be performed in this way.

[0053] In one implementation, such as Figures 1 to 16 As shown, the probe mounting base 11 also includes two mounting ends, located on either side of the detection end. Each mounting end is equipped with a skin-adhesive mechanism, which includes a movable adhesive plate 12. The movable adhesive plate 12 is hinged to the mounting end and has a contact surface for contacting the skin. A skin-friendly adhesive patch 17 is provided on the contact surface for adhesion to the skin. The hinge axis of the movable adhesive plate 12 is parallel to the contact surface, allowing the movable adhesive plate 12 to rotate towards or away from the skin. The number of movable adhesive plates 12 is not limited and can be set according to actual needs. For example, one movable adhesive plate 12 can be provided on each of the two mounting ends, or multiple movable adhesive plates 12 can be provided on each end. Preferably, the movable adhesive plates 12 are symmetrically arranged on the two mounting ends. When using, first peel off the protective paper on the skin-friendly adhesive patch 17, then bring the skin-friendly adhesive patch 17 of the movable adhesive plate 12 into contact with the skin, and then gently press the movable adhesive plate 12. When removing it, you also need to gently peel off the movable adhesive plate 12.

[0054] In one implementation, such as Figures 1 to 16 As shown, both mounting ends of the probe mounting base 11 are provided with buckles 121, and the movable adhesive plate 12 is provided with a hinge shaft 122. By snapping the hinge shaft 122 into the buckles 121, the movable adhesive plate 12 and the probe mounting base 11 can be hinged.

[0055] In one implementation, such as Figures 1 to 16As shown, the probe mounting base 11 also includes a plug-in end located between the two mounting ends. The plug-in end has a T-shaped slot 15, which is mainly composed of mutually perpendicular horizontal grooves 151 and vertical grooves 152. The end of the vertical groove 152 furthest from the horizontal groove 151 communicates with the detection port 16. The ultrasonic probe 2 is installed inside the T-shaped plug 21, which is mainly composed of mutually perpendicular horizontal head sections 211 and vertical head sections 212. The horizontal head section 211 is used to insert into the horizontal groove 151, and the vertical head section 212 is used to insert into the vertical groove 152. The end of the vertical head section 212 furthest from the horizontal head section 211 has a mounting port 213, through which the ultrasonic probe 2 can be inserted. A cable groove (not shown in the figure) should be reserved at the mounting port 213 to facilitate the insertion of the cable 22 into the vertical head section 212. The T-shaped slot 15 and the T-shaped plug 21 form a locking mechanism. Preferably, a gap is reserved between the mounting port 213 and the ultrasonic probe 2 for using a sterile probe protective sleeve for the ultrasonic probe 2. The ultrasonic probe 2 + protective sleeve and the mounting port 213 are relatively fixed by friction. The gap is about 0.5mm, which can prevent the ultrasonic probe 2 and the mounting port 213 from being too tightly connected, which would prevent the sterile environment from being protected.

[0056] In one implementation, such as Figures 1 to 16 As shown, the probe mounting base 11 also includes a opposite end, located opposite the insertion end. The puncture needle seat mounting mechanism includes an in-plane puncture needle seat socket 13 and an out-of-plane puncture needle seat socket 14. Both the in-plane puncture needle seat socket 13 and the out-of-plane puncture needle seat socket 14 include insertion blocks, with hemispherical recesses 19 on both sides of the insertion blocks. The insertion blocks are used for insertion into the insertion slot 41 of the puncture needle seat 4. The hemispherical recesses 19 are used for the hemispherical protrusions 42 in the insertion slot 41 of the puncture needle seat 4 to achieve positioning. The in-plane puncture needle seat socket 13 is mounted on the opposite end, and the out-of-plane puncture needle seat socket 14 is mounted on one of the mounting ends. The movable adhesive plate 12 on the mounting end where the out-of-plane puncture needle seat socket 14 is mounted has a through-hole 18 for the puncture needle 5 to pass through, and preferably also allows the out-of-plane puncture needle seat socket 14 to pass through. Of course, the through-hole 18 can also be set on the movable adhesive plate 12 on the other installation end. It doesn't mean that it can't be set, it just means that it's not needed.

[0061] S2. Insert the packaged ultrasound probe 2 into the puncture frame;

[0062] S3. Align the detection port 16 of the probe mounting base 11 with the skin of the operating area, start the ultrasound probe 2, and move the probe mounting base 11 for ultrasound positioning before puncture.

[0063] S4. After determining the puncture location, install a disposable puncture needle holder 4 at a suitable angle, hold the probe mounting base 11, and attach the skin adhesion mechanism to the skin to fix the probe mounting base 11 and the ultrasound probe 2.

[0064] S5. The puncture needle 5 is inserted through the guide hole 43 of the puncture needle seat 4.

[0065] S6. Operation complete. Withdraw the puncture needle 5 and apply local pressure with a cotton swab.

[0066] S7. After applying pressure to stop the bleeding according to the standard procedure, remove the skin adhesive device, remove the probe mounting base 11, clean the operating area, and apply appropriate bandaging and covering.

[0067] S8. Remove the ultrasound probe 2 and the puncture needle seat 4. After removing the protective cover of the ultrasound probe 2, the assistant cleans the ultrasound probe 2 to prepare for the next interventional procedure.

[0068] The specific operating procedures and order of the above usage methods are for reference only and are not required to be performed in this way.

[0069] In one implementation, such as Figures 1 to 16 As shown, it also includes an ultrasound host 3. The ultrasound probe 2 is connected to the ultrasound host 3 via a cable 22. The ultrasound information collected by the ultrasound probe 2 is transmitted to the ultrasound host 3.

[0070] In one implementation, such as Figures 1 to 16 As shown, the ultrasound probe 2 is a single linear array high-frequency probe. The ultrasound probe 2 contains a vibration unit and a receiving unit, and is connected to the ultrasound host 3 via cable 22. Specifically, the ultrasound probe 2 is a 128-element 10-14.0MHz linear array probe, with 32 physical channels for image transmission. The width of the ultrasound probe 2 is 3cm, the maximum detection depth is 40mm, the minimum detection depth is 20mm, and it uses a global focusing mode. The parameters of the ultrasound probe 2 above are reference values ​​and do not imply that only these parameters can be used.

[0071] In one implementation, such as Figures 1 to 16As shown, the ultrasound host 3 includes a host casing 31, a management motherboard, an ultrasound motherboard, and a power supply. The management motherboard, ultrasound motherboard, and power supply are installed inside the host casing 31. The ultrasound probe 2 is electrically connected to the ultrasound motherboard via a cable 22. The host casing 31 has an extension hole for the cable 22 to extend through. The management motherboard is electrically connected to the ultrasound motherboard. The ultrasound signal from the ultrasound probe 2 is processed by the ultrasound motherboard and then transmitted to the display terminal via the management motherboard. The power supply provides power to the management motherboard and the ultrasound motherboard. The host casing 31 has a power switch 32 and a heat dissipation hole 33. The power switch 32 is electrically connected to the power supply.

[0072] Specifically, the main unit casing 31 can be made of plastic, and the whole unit adopts an integrated sealed waterproof design.

[0073] The ultrasonic mainboard mainly consists of an ultrasonic signal receiving unit, a processing unit, and an output unit. It is responsible for organizing, converting electrical signals to digital signals, and optimizing signals from the ultrasonic probe 2. The processed data is then transmitted to the display terminal via the management mainboard.

[0074] The management motherboard includes a data transmission module and a software module. The data transmission module can operate wirelessly, transmitting processed ultrasound data to a mobile display terminal via Wi-Fi. It also receives user commands to adjust ultrasound parameters on the display terminal software, thus performing image transmission and adjustment functions. The software module runs the device's own management program, coordinates data interaction between the data transmission module and the ultrasound motherboard, and manages the normal operation of the power supply.

[0075] The power supply mainly consists of a battery and a wireless charging module. Considering the application environment, the whole system adopts a sealed and waterproof design. The device uses wireless charging to replenish power, and the battery can be a lithium battery or other conventional batteries.

[0076] In one implementation, such as Figures 1 to 16 As shown, a maintenance port is provided at one end of the main unit casing 31, and a sealing cover 34 is detachably installed on the maintenance port.
