Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a vaginal puncture stand for pelvic ultrasonic interventional treatment. Background Art

[0002] A vaginal biopsy holder is a medical aid used in conjunction with ultrasound and other medical equipment. It has a wide range of applications in the treatment of pelvic gynecological disorders and reproductive medicine. It primarily assists the puncture needle in accurately locating and puncturing the target lesion for treatment or diagnosis. When used in conjunction with ultrasound and other medical equipment, a vaginal biopsy holder enables precise puncture positioning, minimizing errors and damage.

[0003] The current structure of the vaginal puncture frame is generally as described in the pelvic ultrasound interventional treatment positioning transmitter used in conjunction with the vaginal puncture frame disclosed in patent application number "201710509974.6", including a spring seat, a sleeve, a piston, a trigger mechanism, an elastic member, a needle seat and a puncture needle; the rear end of the spring seat is connected to the front end of the sleeve; the piston is movably sleeved in the sleeve; the outer surface of the front end of the piston is provided with a convex pin, and the inner surface of the rear end of the sleeve is provided with a matching groove, and the convex pin is detachably embedded in the groove; the groove is communicated with the outside, and the trigger mechanism can extend into the groove from the outside of the sleeve; the rear end of the elastic member is fixedly connected to the needle seat, and the front end passes through the piston and the sleeve and is fixedly connected to the spring seat; the front end of the needle seat is fixedly connected to the rear end of the piston; the needle seat, piston, sleeve and spring seat are all connected, the puncture needle passes through the spring seat, piston and sleeve, and the rear end is connected to the needle seat. The pelvic ultrasound interventional therapy positioning transmitter further includes a vaginal puncture frame, the rear end of which is connected to the front end of the spring seat, and the rear end of which is threadedly connected to the front end of the spring seat.

[0004] However, the vaginal puncture frame of this invention has a simple structure and requires a guide frame to be installed on the ultrasound probe. First, the ultrasound probe is pushed into the vagina, and a suitable puncture path and angle are selected. Then, the vaginal puncture frame is pushed into the vagina and its position is adjusted to correspond to the puncture point on the ultrasound image. This cannot achieve precise positioning of the puncture and is prone to accidentally injuring normal tissue around the puncture point.

[0005] Therefore, the present invention proposes a vaginal puncture stand for pelvic ultrasound interventional therapy to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a vaginal puncture frame for pelvic ultrasound interventional treatment, which is used to solve the problem that the vaginal puncture frame in the prior art cannot accurately position the puncture and is prone to accidentally injuring normal tissues around the puncture point.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] A vaginal puncture holder for pelvic ultrasonic interventional treatment includes a main body with a puncture needle guide groove provided longitudinally therethrough; the main body is composed of a guide portion, a fixing portion and a connecting portion in sequence along the longitudinal direction; the guide portion is cylindrical, and a guide slope is provided at the end of the guide portion, and a chamfer is provided on the guide slope; the fixing portion is composed of a central axis and two arc plates symmetrically arranged along the central axis, and the edges of the arc plates are arranged in a wavy shape; the connecting portion is cylindrical, and an anti-slip protrusion is connected to the connecting portion.

[0009] By adopting the above technical solution, the friction force can be increased during the connection process between the female puncture holder, the puncture device and the puncture needle, and it can also serve as a sign to remind that the female puncture holder is a disposable item, thereby avoiding cross-infection problems caused by repeated use, reducing the resistance during the use of the female puncture holder, improving smoothness, and avoiding harm to the human body.

[0010] Furthermore, the end of the connecting portion is fixedly connected with a threaded connection port, and the threaded connection port is connected to the puncture needle guide groove.

[0011] By adopting the above technical solution, the main body of the female puncture frame can be connected to the puncture device and the puncture needle through the threaded connection port.

[0012] Furthermore, a stent steel core is connected in the puncture needle guide groove.

[0013] By adopting the above technical solution, the main structure of the female puncture frame is made stable and reliable, and can provide sufficient supporting force to ensure stability during the puncture process.

[0014] Furthermore, the threaded connection port and the end of the bracket steel core are both chamfered.

[0015] By adopting the above technical solution, the operation of the puncture needle can be guided.

[0016] Furthermore, a clamping block is fixedly connected to the inner side of the end portion of the arc plate away from the central axis.

[0017] Furthermore, a plurality of positioning beams are fixedly connected between the two arc plates, and the positioning beams are fixedly connected to the central axis.

[0018] By adopting the above technical solution, the friction between the intracavitary ultrasound probe and the female puncture frame can be increased, thereby ensuring the stability of the connection of the intracavitary ultrasound probe.

[0019] Furthermore, a positioning column is fixedly connected to the same side of the guide portion and the positioning beam.

[0020] By adopting the above technical solution, it can be ensured that the vaginal puncture frame is tightly connected to the intracavitary ultrasound probe and that the position is accurate.

[0021] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0022] The utility model can place the intracavitary ultrasound probe directly into the vagina, close to the cervix and posterior fornix, so that the sound beam can penetrate the target tissue more directly. The puncture needle can perform the puncture operation under the real-time guidance of ultrasound, and the path and position of the puncture needle can be clearly seen during the puncture process, thereby achieving precise positioning, avoiding accidental injury to surrounding normal tissues, and improving the safety of treatment.

Obviously, the embodiments described are 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 making creative efforts shall fall within the scope of protection of the present invention.

[0030] In this application, terms such as "upper," "inner," "outer," and "middle" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to specific positions, or to their construction or operation in a specific position.

[0031] like Figure 1-3 As shown, a vaginal biopsy holder for pelvic ultrasound interventional therapy comprises a main body 1, with a puncture needle guide groove 8 extending longitudinally therethrough. The main body 1 is longitudinally composed of a guide portion 2, a fixing portion 3, and a connecting portion 4. The guide portion 2 is cylindrical, with a guide bevel at its end and a chamfered corner. The fixing portion 3 comprises a central axis 5 and two circular plates 6 symmetrically arranged along the central axis 5, with the edges of the circular plates 6 wavy. This reduces resistance during use of the vaginal biopsy holder, improves smoothness, and prevents harm to the human body. A retaining block 10 is fixedly attached to the inner side of the end of the circular plate 6 away from the central axis 5. The connecting portion 4 is cylindrical and has anti-slip protrusions 11 attached thereto. These increase friction during connection between the vaginal biopsy holder, the puncture device 14, and the puncture needle 15, and also serve as a reminder that the vaginal biopsy holder is disposable, preventing cross-infection from repeated use.

[0032] like Figure 3 As shown, the end of the connecting portion 4 is fixedly connected to a threaded connection port 12, which is arranged to extend through the puncture needle guide groove 8. The main body 1 of the female puncture holder is then connected to the puncture device 14 and puncture needle 15 via the threaded connection port 12. A support steel core 13 is connected within the puncture needle guide groove 8. This ensures that the main body 1 of the female puncture holder is structurally stable and reliable, providing sufficient support and ensuring stability during the puncture process. The ends of the threaded connection port 12 and the support steel core 13 are both chamfered.

[0033] like Figure 4 As shown, multiple positioning beams 7 are fixedly connected between the two arc plates 6. The positioning beams 7 are fixedly connected to the central axis 5, thereby increasing the friction between the intracavitary ultrasound probe 16 and the female puncture frame, ensuring the stability of the connection between the intracavitary ultrasound probe 16. Positioning posts 9 are fixedly connected to the same side of the guide portion 2 as the positioning beams 7. This ensures that the female puncture frame and the intracavitary ultrasound probe 16 are tightly connected and accurately positioned.

[0034] The working process of this utility model is:

[0035] First, a pelvic ultrasound examination is performed to determine the size, shape, and location of the lesion, and the patient is routinely disinfected to ensure a sterile state. Then, the main body 1 of the vaginal puncture frame is connected to the puncture device 14 and the puncture needle 15 through the threaded connection port 12. Then, an intracavitary ultrasound probe 16 is installed on the vaginal puncture frame through the arc plate 6. Then, the vaginal puncture frame is pushed into the vagina. The intracavitary ultrasound probe 16 can be directly placed in the vagina, close to the cervix and posterior fornix, so that the sound beam can penetrate the target tissue more directly, and the puncture needle 15 can perform the puncture operation under the real-time guidance of ultrasound.
