Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, products, or devices.

[0035] See also Figure 1 A puncture fixing and regulating device provided in an embodiment of the present invention comprises: a probe fixing component 1 and a puncture regulating component 2. The puncture regulating component 2 is connected to one end of the probe fixing component 1. The probe fixing component 1 is used to install and fix an ultrasonic probe 3. The puncture regulating component 2 comprises: a connecting frame 21, a puncture needle direction regulating structure 22, a puncture needle propulsion structure 23 and a puncture needle 24. The connecting frame 21 is connected to one end of the probe fixing component 1. Specifically, through holes are respectively provided on the connecting frame 21 and the probe fixing component 1, and the connecting frame 21 and the probe fixing component 1 are connected by threaded connectors such as bolts passing through the through holes. The puncture needle direction regulating structure 22 is connected to the connecting frame 21. The puncture needle propulsion structure 23 is connected to the puncture needle direction regulating structure 22. The puncture needle 24 is arranged on the puncture needle propulsion structure 23. The puncture needle direction regulating structure 22 is used to drive the puncture needle propulsion structure 23 and the puncture needle 24 to rotate to a specific angle so that the puncture needle 24 is in a target direction.

[0036] The puncture fixing and regulating device provided in the embodiment of the present invention is connected to the puncture needle propulsion structure 23 by setting the puncture needle direction regulating structure 22, and the puncture needle 24 is set on the puncture needle propulsion mechanism 23, so that the puncture direction of the puncture needle 24 can be accurately regulated. Users such as doctors can use the puncture needle direction regulating structure 22 to drive the puncture needle propulsion structure 23 and the puncture needle 24 to rotate to a specific angle so that the puncture needle 24 is in the target direction. In summary, the user can accurately adjust the puncture direction of the puncture needle 24 by controlling the puncture needle direction regulating structure 22, ensure that the puncture needle 24 can be aligned with the predetermined puncture point, and improve the accuracy of the puncture direction.

[0037] In addition, the user can also control the advancement and retreat of the puncture needle 24 through the puncture needle propulsion structure 23 to adjust the puncture depth and reduce the risk of over-puncture or under-puncture. In addition, the puncture needle 24 is made of, for example, a high-hardness, low-traumatic material in the prior art, and is precisely processed to ensure its sharpness and strength, so that it can smoothly penetrate the target tissue structure and reduce damage to surrounding normal tissues.

[0038] Specifically, Figure 1-4 As shown, an axial hole 214 is provided on one end of the connecting frame 21 away from the probe fixing assembly 1. The puncture needle direction control structure 22 includes: a rotating shaft 221, a gear 222, a rack 223, a housing 224 and a first adjusting member 225. The rotating shaft 221 is inserted into the axial hole 214, and the rotating shaft 221 can rotate relative to the connecting member 21. The puncture needle propulsion structure 23 is connected to the rotating shaft 221 and can rotate with the rotating shaft 221. The gear 222 is sleeved and fixedly connected to one end of the rotating shaft 221. The rack 223 meshes with the gear 222 to form a gear transmission. The housing 224 is covered outside the gear 222 and the rack 223, and is connected to the other end of the connecting frame 21, and a first threaded hole 2241 is provided on the housing 224. The first adjusting member 225 has a first screw 2251 matched with the first threaded hole 2241 and a first adjusting portion 2252 connected to one end of the first screw 2251. The first adjusting member 225 is threadedly connected to the first threaded hole 2241 through the first screw 2251, and the other end of the first screw 2251 is connected to the rack 223. Specifically, the other end of the first screw 2251 is connected to the rack 223 by, for example, a threaded connection, and forms a movable connection, that is, when the first screw 2251 rotates, the rack 223 does not rotate. Among them, when the first adjusting member 225 rotates relative to the first threaded hole 2241, the first adjusting member 225 can drive the rack 223 to move in the housing 224, further drive the gear 222, the rotating shaft 221 and the puncture needle propulsion structure 23 to rotate, and finally the puncture needle 24 rotates to the target direction.

[0039] In this embodiment, the puncture needle propulsion structure 23 is connected to the rotating shaft 221, so that the puncture needle direction control structure 22 can control the rotation direction and angle of the puncture needle propulsion structure 23 and the puncture needle 24. The rotating shaft 221 is fixedly connected to the gear 222, so that the rotating shaft 221 can rotate with the gear 222, and the first adjustment member 225 of the puncture needle direction control structure 22 is connected to the rack 223 through the first threaded hole 2241 on the housing 224, and the rack 223 is meshed with the gear 222, so that when the first adjustment member 225 rotates relative to the first threaded hole 2241, it can drive the puncture needle propulsion structure 23 to rotate, thereby regulating the puncture direction of the puncture needle 24. Specifically, when the user rotates the first adjusting member 225, since the first screw 2251 of the first adjusting member 225 is threadedly connected with the rack 223, the rack 223 moves upward or downward under the action of the first screw 2251, thereby driving the gear 222 to rotate clockwise or counterclockwise. When the gear 222 rotates clockwise, the rotating shaft 221 drives the puncture needle propulsion structure 23 to rotate toward the direction approaching the probe fixing assembly 1; when the gear 222 rotates counterclockwise, the rotating shaft 221 drives the puncture needle propulsion structure 23 to rotate away from the probe fixing assembly 1.

[0040] Furthermore, the thread lead angle of the first screw 2251 and the first threaded hole 2241 is less than or equal to the friction angle. In this way, when the thread lead angle is less than or equal to the friction angle, the first screw 2251 and the first threaded hole 2241 will form a self-locking structure, which can ensure that after the puncture needle 24 is adjusted to a specific position, the direction of the puncture needle 24 remains stable after the user lets go and will not rotate automatically. This design effectively prevents the direction of the puncture needle 24 from changing automatically, simplifies the mechanical structure, and realizes the self-locking function.

[0041] In another embodiment of the present invention, Figure 3-6As shown, the housing 224 is also provided with an opening 2243. A first pin 211, a second pin 212 and a third pin 213 are provided on the side of the connecting frame 21 adjacent to the housing 224. The puncture regulating assembly 2 also includes a locking structure 25, specifically, the locking structure 25 includes: a locking block 251 and a tension spring (not shown in the figure). The locking block 251 is provided with a pin hole 2511, and the locking block 251 is sleeved on the first pin 211 through the pin hole 2511, and the locking block 251 can be equivalent to the rotation of the connecting frame 21. When the locking block 251 abuts against the second pin 212, one end of the locking block 251 adjacent to the gear 222 can abut between two adjacent gear teeth of the gear 222 through the opening 2243; a fourth pin 2512 is provided on the end of the locking block 251 away from the pin hole 2511. The two ends of the tension spring are respectively connected to the third pin shaft 213 and the fourth pin shaft 2512 and are in a tension state.

[0042] The opening 2243 on the housing 224 allows the locking block 251 to pass through the housing 224 and directly contact the gear teeth of the gear 222, so that the locking block 251 can be clamped between two adjacent gear teeth of the gear 222 when it abuts against the second pin shaft 212, thereby fixing the gear 222 and preventing the gear 222 from rotating. In the absence of other external forces, the gear 222 is locked, and the direction of the puncture needle 24 is finally locked. By setting the second pin shaft 212, the locking block 251 is blocked in an appropriate position, so that the locking block 251 will not rotate when locking the gear 222, thereby enhancing the stability of the locking. The fourth pin shaft 2512 of the locking block 251 is connected to the third pin shaft 213 via the tension spring. The tensioned state of the tension spring provides the necessary elastic force for the locking block 251, ensuring the close contact between the locking block 251 and the gear teeth of the gear 222. The locking block 251 can be clamped between two adjacent gear teeth of the gear 222, thereby enhancing the locking stability.

[0043] Specifically, the end of the locking block 251 that contacts the gear 222 may be a rectangular or trapezoidal cross section, so that it can be effectively engaged between two adjacent gear teeth of the gear 222. When using the locking structure 25, the user can rotate the locking block 251 to a position abutting against the second pin 212, and abut one end of the locking block 251 between two adjacent gear teeth of the gear 222, so that the gear 222 is in a locked state, thereby fixing the puncture direction of the puncture needle 24, and achieving accurate and stable puncture direction. When the puncture direction of the puncture needle 24 needs to be adjusted again, press the end of the locking block 251 away from the gear 222 to unlock the gear 222. At this time, the user can rotate the first adjusting member 225 to drive the gear 222 to rotate again to adjust the puncture direction of the puncture needle 24.

[0044] Furthermore, if Figure 4 and Figure 5 As shown, the shell 224 is provided with a through hole 2244, and an angle indicator 2242 is provided on the outer surface of the shell 224 adjacent to the through hole 2244, which provides a user with an intuitive angle reading, and facilitates the rapid and accurate adjustment and confirmation of the puncture direction of the puncture needle 24. Specifically, the angle indicator 2242 is provided with an angle scale, and its angle range is, for example, -90° to 90°, or even 0-90°, or other suitable ranges, which can be set according to actual needs, and the embodiment of the present invention is not limited thereto. Each scale on the angle indicator 2242 corresponds to a rotation angle of the puncture needle 24. Furthermore, a pointer 2211 is provided on the one end of the rotating shaft 221, and the pointer 2211 extends out of the shell 224 and is located in the indication range of the indicator plate 2242. The angle value indicated by the pointer 2211 corresponds to the angle of the puncture needle 24, so that the pointer 2211 can directly indicate the current angle of the puncture needle 24 on the angle indicator plate 2242, which is convenient for the user to make precise adjustments and also provides the user with an intuitive angle reading, which can conveniently, quickly and accurately adjust and confirm the puncture direction of the puncture needle.

[0045] Furthermore, if Figure 7 and Figure 8As shown, an escape groove 215 is also provided at one end of the connecting frame 21 away from the probe fixing assembly 1, which can provide sufficient activity space for the puncture needle propulsion structure 23. The rotating shaft 221 is rotatably connected to the shaft hole 214 on both sides of the escape groove 215. The puncture needle propulsion structure 23 includes: a support member 231 and a second adjustment member 232. The support member 231 is installed on the rotating shaft 221 and is located in the escape groove 215, and a second threaded hole 2311 is provided on the support member 231. The second adjustment member 232 has a second screw 2321 matching the second threaded hole 2311 and a second adjustment portion 2322 connected to one end of the second screw 2321, and the second adjustment member 232 is threadedly connected to the second threaded hole 2311 of the support member 231 through the second screw 2321. The puncture needle 24 is connected to one end of the second screw rod 2321 away from the second adjusting portion 2322 and passes through the second threaded hole 2311 .

[0046] Specifically, a through hole may be provided on the rotating shaft 221, and the support member 231 passes through the through hole on the rotating shaft 221 and is welded to the rotating shaft 221, so as to realize a fixed connection between the support member 231 and the rotating shaft 221. In addition, the rotating shaft 221 and the support member 231 may also be an integrally formed structure, which may be specifically configured according to actual conditions, and this embodiment does not limit this.

[0047] The puncture needle propulsion structure 23 provided in the embodiment of the present invention can move with the rotation of the rotating shaft 221 in the avoidance groove 215, thereby providing the puncture needle 24 with a multi-angle puncture direction. When puncture is required, the user can rotate the second adjustment part 2322 of the second adjustment member 232, thereby driving the puncture needle 24 to move downward to complete the puncture. By setting the puncture needle propulsion structure 23, the user can accurately control the puncture depth of the puncture needle 24, and when the puncture needle 24 reaches the required puncture depth, due to the limitation of the second adjustment member 232, the puncture needle 24 is fixed at the required puncture depth, thereby enhancing the accuracy and stability of the puncture. When the puncture is completed, the user can reversely rotate the second adjustment part 2322 of the second adjustment member 232, thereby driving the puncture needle 24 to move upward, so that the puncture needle 24 is away from the patient's skin.

[0048] Furthermore, if Fig. 9As shown, the connecting frame 21 is provided with a clamping groove 216 and a first connecting hole 217 at one end adjacent to the probe fixing assembly 1, the connecting frame 21 is clamped at one end of the probe fixing assembly 1 through the clamping groove 216, the one end of the probe fixing assembly 1 is provided with a second connecting hole 11, and the first connecting hole 217 of the connecting frame 21 is connected to the second connecting hole 11 at the one end of the probe fixing assembly 1. Specifically, the first connecting hole 217 of the connecting frame 21 is connected to the second connecting hole 11 at the one end of the probe fixing assembly 1 by bolts, thereby realizing the connection between the probe fixing assembly 1 and the puncture regulating assembly 2.

[0049] like Fig.10 As shown, another embodiment of the present invention further provides an ultrasonic puncture system, which includes the puncture fixation control device and the ultrasonic probe 3 described in any of the above embodiments. The ultrasonic probe 3 is, for example, a mature ultrasonic probe in the prior art, and its specific structure is not repeated here. The ultrasonic probe 3 is installed on the probe fixing assembly 1, so as to provide the user with real-time internal tissue imaging, assist the user in accurate positioning and navigation, and ensure that the puncture needle 24 accurately reaches the target area. Among them, the probe fixing assembly 1 is made of hard plastic with a certain elasticity, and the probe fixing assembly 1 is composed of two U-shaped structures. When the ultrasonic puncture system is used, the two U-shaped structures are connected by bolts or the like to fix the ultrasonic probe 3. Furthermore, the ultrasonic puncture system also includes an ultrasonic probe sterile protective cover (not shown in the figure), which is arranged outside the ultrasonic probe 3 and between the probe fixing assembly 1 and the ultrasonic probe 3. By arranging the ultrasonic probe sterile protective cover between the probe fixing assembly 1 and the ultrasonic probe 3, a sterile environment is provided for the ultrasonic probe 3, preventing the probe surface from being contaminated by microorganisms, and reducing the risk of intraoperative infection. Secondly, by preventing the probe from directly contacting contaminants and reducing the frequency of cleaning and disinfection, the ultrasonic probe sterile protective cover helps to extend the service life of the probe.

[0050] Specifically, the probe fixing assembly 1 is closed and tightly surrounds the outside of the sterile protective cover of the ultrasound probe; the probe fixing assembly 1 has an auxiliary clamping effect on the sterile protective cover of the ultrasound probe. Before puncture, the user wraps the sterile protective cover of the ultrasound probe around the ultrasound probe 3, and then closes and fixes the two U-shaped structures of the probe fixing assembly 1 around the ultrasound probe 3, so as to select a suitable puncture path according to the ultrasound image.

[0051] Furthermore, an adhesive coating (not shown) with a certain adhesive ability is also provided inside the ultrasound probe sterile protective cover. The adhesive coating provides additional adhesive force, which helps to fix the position of the ultrasound probe sterile protective cover on the ultrasound probe 3 and reduce sliding or displacement during use.

Under the premise that the technical features do not conflict, are not contradictory, and do not violate the purpose of the present invention, the technical solutions of the various embodiments can be arbitrarily combined and used in combination.
