[0002] Ultrasonic puncture probe is an important tool for interventional ultrasound. It is developed on the basis of ultrasound imaging to further meet the needs of clinical diagnosis and treatment. Its main function is to complete various biopsies, fluid extraction, puncture angiography, catheter drainage, blood transfusion, lesion injection, etc. under the monitoring and guidance of real-time ultrasound. It can avoid certain surgical operations and achieve the same effect as surgical operations.

[0003] The head of the ultrasonic puncture probe is provided with a puncture hole. Through the cooperation of the ultrasonic puncture probe and the puncture needle, puncture, drainage, biopsy, injection and other operations can be performed during the operation. Before puncturing, the traditional ultrasonic puncture probe will first perform an ultrasonic examination on the target tissue. When the ultrasonic puncture probe finds the position where the target tissue can be best displayed, the puncture needle is inserted from the puncture hole of the ultrasonic puncture probe into the target tissue for operation. The ultrasonic puncture probe needs to ensure that the puncture needle remains stable and motionless. When the ultrasonic puncture probe and the puncture needle are coordinated, there is a problem of poor stability of the fixed position of the puncture needle. These problems may increase the risk of surgery, reduce patient comfort, and have unsatisfactory surgical results. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the ultrasonic puncture probe and ultrasonic equipment provided by the embodiment of the utility model are: by providing a plug-in slot on the plug-in portion, and clamping the needle sleeve mounted on the puncture needle at the plug-in slot, the puncture needle can only perform puncture operations along the needle sleeve; wherein, because the force applied to the puncture needle is difficult to be completely along the puncture direction, part of the force in the non-puncture direction will produce a pressing effect on the inner wall of the needle sleeve, thereby increasing the relative friction between the outer wall of the needle sleeve and the inner wall of the plug-in slot. Secondly, when the puncture needle performs a puncture operation, the sliding of the puncture needle will cause the entire needle sleeve to have a tendency to displace along the puncture direction, and the relative friction between the outer wall of the needle sleeve and the inner wall of the plug-in slot will cause the needle sleeve to have a tendency to slide in the opposite direction of the puncture direction, and the two will offset each other, thereby making the fixed position of the puncture needle relatively stable. In addition, the integrated setting of the probe body and the plug-in part enables the needle sleeve to maintain a stable relative position to the ultrasonic puncture probe as a whole, so that when the ultrasonic puncture probe and the puncture needle are coordinated, the fixed position of the puncture needle maintains good stability, thereby reducing the surgical risk caused by the displacement of the puncture needle, reducing the pain caused by the displacement of the puncture needle to improve the patient's comfort, and ultimately obtaining a more ideal surgical effect.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0025] like Figures 1 to 3 As shown, the utility model discloses an ultrasonic puncture probe 1, including a probe body 11 and a puncture assembly 12, wherein a plug-in portion 111 is formed at one end of the probe body 11, and a plug-in groove 1111 is formed on the plug-in portion 111; the puncture assembly 12 includes a puncture needle 121 and a needle sleeve 122 sleeved on the puncture needle 121, and the needle sleeve 122 can be clamped in the plug-in groove 1111, and the puncture needle 121 is used to perform puncture operations along the needle sleeve 122.

[0026] By opening a plug-in slot 1111 on the plug-in portion 111, and clamping the needle sleeve 122 on the puncture needle 121 at the plug-in slot 1111, the puncture needle 121 can only perform puncture operations along the needle sleeve 122; wherein, since it is difficult for the force applied to the puncture needle 121 to be completely along the puncture direction, part of the force in the non-puncture direction will produce a pressing effect on the inner wall of the needle sleeve 122, thereby increasing the relative friction between the outer wall of the needle sleeve 122 and the inner wall of the plug-in slot 1111. Secondly, when the puncture needle 121 is puncturing, the sliding of the puncture needle 121 will cause the entire needle sleeve 122 to have a tendency to move along the puncture direction, and the relative friction between the outer wall of the needle sleeve 122 and the inner wall of the plug-in slot 1111 will cause the needle sleeve 122 to have a tendency to slide in the opposite direction of the puncture direction, and the two will offset each other, thereby making the fixed position of the puncture needle 121 relatively stable. In addition, the integrated arrangement of the probe body 11 and the plug-in portion 111 enables the needle sleeve 122 to maintain a stable relative position to the ultrasonic puncture probe 1 as a whole, so that when the ultrasonic puncture probe 1 and the puncture needle 121 cooperate, the fixed position of the puncture needle 121 maintains good stability, thereby reducing the surgical risk caused by the displacement of the puncture needle 121, reducing the pain caused by the displacement of the puncture needle 121 to improve the patient's comfort, and ultimately obtaining a more ideal surgical effect.

[0027] The plug-in slot 1111 can not only serve as a positioning guide for the puncture component 12, but also facilitate the replacement and removal of the puncture component 12, so as to achieve a quick separation of the puncture component 12 and the ultrasonic puncture probe 1 after the puncture operation is completed, and the puncture component 12 and the ultrasonic puncture probe 1 can be cleaned and disinfected as needed.

[0028] Further, see Figure 3 The needle sleeve 122 includes a needle sleeve body 1221 and a clamping section 1222 which are connected to each other. The diameter of the outer circle of the clamping section 1222 is larger than the diameter of the outer circle of the needle sleeve body 1221, so that the needle sleeve body 1221 can be inserted into the insertion groove 1111, and the clamping section 1222 is clamped with the insertion groove 1111.

[0029] First, when the puncture needle 121 is performing a puncture operation, since it is difficult for the force applied to the puncture needle 121 to be completely in the puncture direction, part of the force in the non-puncture direction will produce a pressing effect on the inner wall of the clamping section 1222, thereby increasing the relative friction between the outer wall of the clamping section 1222 and the inner wall of the plug-in slot 1111. Secondly, when the puncture needle 121 is performing a puncture operation, the sliding of the puncture needle 121 will cause the entire needle sleeve 122 to have a tendency to move in the puncture direction, and the relative friction between the outer wall of the clamping section 1222 and the inner wall of the plug-in slot 1111 will cause the clamping section 1222, i.e., the needle sleeve 122, to have a tendency to slide in the opposite direction of the puncture direction, and the two will offset each other, thereby making the fixed position of the puncture needle 121 relatively stable.

[0030] Furthermore, if Figure 1 and Figure 2 As shown, the plug-in portion 111 extends toward one side of the end of the probe body 11, and a plurality of plug-in slots 1111 are provided at intervals in the extension direction of the plug-in portion 111. The arrangement of the plug-in portion 111 can avoid blocking the ultrasonic detection area of ​​the probe body 11, thereby realizing the puncture function without affecting the ultrasonic detection function of the ultrasonic puncture probe 1. The arrangement of the plurality of plug-in slots 1111 can insert the puncture assembly 12 into the plug-in slots 1111 at different positions as required, making the position selection of the puncture needle 121 more flexible, so that the ultrasonic puncture probe 1 can adapt to different usage requirements and have better applicability.

[0031] Specifically, see Figure 1 , Figure 2 , Figure 4 and Figure 5 , the plug-in slot 1111 is arranged at one side edge in the width direction of the plug-in portion 111. The arrangement of the plug-in slot 1111 facilitates the installation and disassembly of the puncture assembly 12, and the orientation of the plug-in slot 1111 is the same as the puncture direction of the puncture needle 121, which facilitates the observation of information such as the puncture depth of the puncture needle 121, and is beneficial to the puncture operation of the puncture needle 121. In addition, when an ultrasonic detection component is also arranged in the plug-in portion 111, the arrangement of the plug-in slot 1111 can not only avoid blocking the ultrasonic detection area, but also avoid the ultrasonic detection component, which is convenient for the arrangement and routing of components inside the plug-in portion 111.

[0032] Furthermore, if Figure 4 and Figure 5 As shown, a positioning groove 1112 is provided on the plug-in portion 111, and the positioning groove 1112 is located on the side of the plug-in portion 111 facing the puncture direction, and the plug-in slot 1111 is located in the positioning groove 1112. The positioning groove 1112 can not only facilitate the processing and positioning of the plug-in slot 1111, but also reduce the processing difficulty of the plug-in slot 1111; the positioning groove 1112 can also form a larger open area near the plug-in slot 1111, so as to facilitate the observation and adjustment of the clamping fit between the puncture assembly 12 and the plug-in slot 1111.

[0033] Specifically, see Figure 1 and Figure 2 The side of the probe body 11 away from the positioning groove 1112 is a convex arc surface. This arrangement can make the probe body 11 fit the patient's skin better when in use, which can not only improve the accuracy of ultrasonic detection and puncture operations, but also improve the patient's comfort, so that the ultrasonic puncture probe 1 has a better product experience.

[0034] Furthermore, if Figure 1 and Figure 4 As shown, the ultrasonic puncture probe 1 further includes a connecting line 13 and a probe socket 14 , and the probe body 11 and the probe socket 14 are electrically connected via the connecting line 13 .

[0035] The connecting wire 13 and the probe socket 14 serve as transmission media to transmit information and current between the probe body 11 and the ultrasound host, so that the ultrasound detection function of the ultrasound puncture probe 1 can be used normally.

[0036] Specifically, see Figure 4 The probe socket 14 includes a socket body 141 and a plug 142 disposed on the socket body 141; the socket body 141 is used to be electrically connected to the ultrasound host through the plug 142. The plug 142 can form a relatively stable connection strength between the socket body 141 and the ultrasound host to ensure that the ultrasound puncture probe 1 and the ultrasound host can work normally after being connected.

[0037] In an alternative embodiment, Figure 4 As shown, the socket body 141 is provided with a locking knob 143 arranged opposite to the plug 142. The locking button 143 can control the locking state between the plug 142 and the ultrasound host. After the plug 142 is effectively connected to the ultrasound host, the locking button 143 can be rotated to lock the plug 142 to prevent the plug 142 from being separated from the ultrasound host and ensure that the ultrasound puncture probe 1 remains in a normal working state during use; when the ultrasound puncture probe 1 needs to be disassembled, it is only necessary to rotate the locking knob 143 again to put the plug 142 in an unlocked state, and the ultrasound puncture probe 1 can be separated from the ultrasound host by unplugging the plug 142.

[0038] The utility model also discloses an ultrasonic device, including an ultrasonic host and the ultrasonic puncture probe 1, wherein the ultrasonic host and the ultrasonic puncture probe 1 are electrically connected. The ultrasonic puncture probe 1 includes the structure and beneficial effects of the ultrasonic puncture probe 1 in the aforementioned embodiment. The structure and beneficial effects of the ultrasonic puncture probe 1 have been described in detail in the aforementioned embodiment and will not be repeated here.

[0039] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
