Description

Technical Field

[0001] This utility model relates to the field of ultrasound medical technology, and in particular to a novel puncture device. Background Technology

[0002] A puncture device, also known as an ultrasound probe puncture frame, puncture guide, or puncture guide, is a device that uses an ultrasound probe to guide a puncture needle to a target location in the body under ultrasound guidance, enabling procedures such as cytological biopsy, histological biopsy, cyst aspiration, and treatment.

[0003] For example, Chinese utility model patent (CN217066533U) discloses an ultrasound interventional puncture device for imaging ultrasound medical use, which describes: "including a support plate; a first U-shaped bracket, the first U-shaped bracket being fixedly installed on the support plate; a first fixing mechanism, the first fixing mechanism being disposed on the first U-shaped bracket."

[0004] However, when not in use, the puncture needles in the above-mentioned devices are mostly exposed by hanging on the rings, which makes it easy for impurities to adhere to the surface of the puncture needles and cause contamination. At the same time, personnel may accidentally touch the puncture needles during the operation of the above-mentioned devices, which may lead to infection risks. Therefore, this application proposes a new type of puncture device. Utility Model Content

[0025] As described in the background art, when the puncture needle in the above-mentioned device is not in use, it is mostly exposed to the outside by simply hanging it with a hanging ring, which makes it easy for impurities to adhere to the surface of the puncture needle and cause contamination. At the same time, personnel may accidentally touch the puncture needle during the operation of the above-mentioned device, which may lead to the risk of infection.

[0026] To solve this technical problem, this utility model provides a novel puncture device for use in ultrasonic medical puncture;

[0027] The device includes a support frame 1, an ultrasound intervention head assembly 2 at one end of the support frame 1, a storage box 3 at the other end of the support frame 1, a stud 4 rotatably connected inside the storage box 3, guide posts 10 symmetrically fixed inside the storage box 3 and outside the stud 4, a mounting base 11 slidably connected between the two guide posts 10, the mounting base 11 being threadedly connected to the stud 4, and a puncture needle body 12 placed inside the mounting base 11.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1:

[0033] Please refer to Figure 1-5 A novel puncture device includes a support frame 1, an ultrasound intervention head assembly 2 is provided at one end of the support frame 1, a storage box 3 is fixed at the other end of the support frame 1, a stud 4 is rotatably connected inside the storage box 3, guide posts 10 are symmetrically fixed inside the storage box 3 and outside the stud 4, a mounting base 11 is slidably connected between the two guide posts 10, the mounting base 11 is threadedly connected to the stud 4, a puncture needle body 12 is placed inside the mounting base 11, and the puncture needle body 12 is slidably connected to the mounting base 11.

[0034] By controlling the rotation of the stud 4, it is convenient to move the puncture needle body 12 upward, thereby making it convenient to pick up the puncture needle body 12. In order to facilitate the rotation of the stud 4, a drive component is provided at the lower end of the stud 4 and at the bottom of the storage box 3.

[0035] Specifically, the drive assembly includes a first spur gear 6, a first spur gear 6 is fixed at the lower end of the stud 4 and located at the lower end of the storage box 3, a reduction motor 7 is fixed at the bottom end of the storage box 3 and located outside the first spur gear 6, and a second spur gear 8 is fixed at the output end of the reduction motor 7, and the second spur gear 8 is meshed with the first spur gear 6.

[0036] In order to seal the storage box 3 and provide a closed storage environment for the puncture needle body 12, the outer side of the storage box 3 is provided with a first L-shaped cover 13 and a second L-shaped cover 14. When the stud 4 rotates and drives the mounting base 11 to move upward through the guide post 10, thereby driving the puncture needle body 12 to move upward for easy removal of the puncture needle body 12, in order to drive the first L-shaped cover 13 and the second L-shaped cover 14 to separate synchronously and thus release the seal of the storage box 3, the upper and lower ends of the inner side of the first L-shaped cover 13 and the second L-shaped cover 14 are fixed with limit guide rods 15. All four limit guide rods 15 are slidably connected to the storage box 3. A linkage component is provided between the first L-shaped cover 13 and the second L-shaped cover 14 and outside the stud 4.

[0037] Specifically, the linkage assembly includes a worm gear 5, a worm gear 5 fixed on the outside of the stud 4 and inside the storage box 3, a first screw 16 and a second screw 17 rotatably connected inside the storage box 3 and outside the worm gear 5, a first L-shaped cover 13 threadedly connected to the first screw 16, a second L-shaped cover 14 threadedly connected to the second screw 17, a first worm 18 fixed on the outside of the first screw 16 and inside the storage box 3, and a second worm 19 fixed on the outside of the second screw 17 and inside the storage box 3. Both the first worm 18 and the second worm 19 are meshed with the worm gear 5.

[0038] Example 2:

[0039] The novel puncture device provided in Example 1 has been further optimized, specifically, as follows: Figure 3-4 As shown, in order to protect the ends of the first screw 16 and the second screw 17 that extend to the outside of the storage box 3, protective sleeves 20 are fixed to the outside of the first L-shaped cover 13 and the second L-shaped cover 14, respectively. The two protective sleeves 20 are located outside the first screw 16 and the second screw 17. In order to further protect the drive assembly, a protective seat 9 is fixed to the bottom of the storage box 3 and outside the first spur gear 6 and the second spur gear 8, so that when the first screw 16, the second screw 17 or the drive assembly moves, it can be effectively prevented from contacting external objects and affecting the stability of the movement.

[0040] All of the above electrical components are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail here.

[0041] The novel puncture device provided by this utility model is used as follows: When medical staff operate the ultrasound intervention head assembly 2 to examine the patient's body, the storage box 3, the first L-shaped cover 13 and the second L-shaped cover 14 provide a closed environment for storing the puncture needle body 12, effectively blocking external impurities and personnel from contacting the puncture needle body 12, thereby greatly reducing the risk of contamination or infection of the puncture needle body 12 and effectively maintaining the medical hygiene of the puncture needle body 12;

[0042] When the puncture needle body 12 needs to be retrieved, simply control the start-up reduction motor 7 to drive the second spur gear 8 to rotate. The meshing of the second spur gear 8 with the first spur gear 6 drives the stud 4 and worm gear 5 to rotate. When the stud 4 rotates, it drives the mounting base 11 to move upward through the guide post 10, causing the puncture needle body 12 to gradually move upward. At the same time, when the worm gear 5 rotates, the meshing of the worm gear 5 with the first worm 18 and the second worm 19 drives the first screw 16 and the second screw 17 to rotate synchronously. This facilitates the synchronous separation of the first L-shaped cap 13 and the second L-shaped cap 14 through the guide rod 15, thus facilitating the gradual release of the seal on the storage box 3 during the upward movement of the puncture needle body 12. When the puncture needle body 12 has finished moving upward, the first L-shaped cap 13 and the second L-shaped cap 14 have also separated synchronously, making it convenient for medical personnel to retrieve the puncture needle body 12.
