Description

Technical Field

[0001] This utility model relates to the field of ultrasonic puncture devices, specifically to an extracorporeal prostate examination puncture device. Background Technology

[0002] Prostate cancer is a malignant tumor that typically occurs in the epithelial cells of the prostate gland ducts. Due to its high incidence, prostate cancer has become a serious global health problem. The 2012 China Cancer Annual Report showed that prostate cancer ranked sixth in incidence among male cancers in China and ninth in cancer-related deaths. Prostate ultrasound examinations utilize the rectal method, where an ultrasound probe is inserted into the rectum to perform transverse or longitudinal scans of the prostate. While the rectal examination method is widely used in medicine, it has the following drawbacks:

[0003] First, the ultrasound probe moves back and forth and rotates left and right in the rectum, which will rub against the inner wall of the rectum and damage the rectal tissue. The rotating ultrasound probe rubs against the rectal wall, causing discomfort to the patient. At the same time, the ultrasound probe compresses the rectal tissue and cannot obtain accurate images.

[0004] Secondly, the movement of the ultrasound probe can compress the rectum, causing changes in the image, which is not conducive to observation and diagnosis.

[0005] Furthermore, before examining the next patient, the ultrasound probe needs to be thoroughly cleaned to avoid cross-infection, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides an external prostate examination puncture device that scans the prostate gland externally at the perineum, reducing trauma to the patient. To achieve the above objectives, this invention is implemented through the following technical solution:

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] like Figures 1 to 9 As shown in the figure, this embodiment discloses an external prostate examination puncture device, including an external ultrasound probe 2 and a puncture frame 1.

[0030] See Figures 3 to 4The puncture frame 1 includes a base, a target block 3, a fixing plate 4, an elastic reset member, and a clamping plate 5. The fixing plate 4 is detachably mounted on the base. The base and the fixing plate 4 cooperate to clamp the external ultrasound probe to fix the puncture frame 1 on the external ultrasound probe. The first end of the clamping plate 5 is rotatably connected to the base. The clamping plate 5 can be rotated to adjust the distance between the second end of the clamping plate 5 and the base. The elastic reset member drives the second end of the clamping plate 5 to tend to move closer to the base, so that the clamping plate and the base cooperate to clamp the target block 3 inserted between the clamping plate 5 and the base. By rotating the clamping plate 5 to release the target block 3, the target block 3 can be removed from between the clamping plate 5 and the base. The target block 3 is provided with at least one row of puncture holes 16 (preferably, 19 puncture holes with a spacing of 2.5 mm). The puncture frame 1 can be quickly assembled and disassembled from the external ultrasound probe 2, and the target block 3 can be removed separately for cleaning.

[0031] In the specific structure, the first end of the clamping plate 5 is rotatably connected to the base via a horizontal rotating shaft 6. In this embodiment, the elastic reset element is a torsion spring 7, which is sleeved on the rotating shaft 6. The first end of the torsion spring 7 is connected to the clamping plate 5, and the second end is connected to the base. A handle 8 is provided on the side of the second end of the clamping plate 5 facing away from the base. Grasping the handle 8 and pulling the clamping plate 5 towards the side facing away from the base causes the clamping plate 5 to rotate, increasing the gap between the second end of the clamping plate 5 and the base. This facilitates the insertion of the target block 3 between the clamping plate 5 and the base. Releasing the handle 8 causes the clamping plate 5 to return to its original position and approach the base under the action of the torsion spring 7, thereby clamping the target block 3. In other embodiments, the handle 8 can also be positioned at other locations on the clamping plate 5. In other embodiments, the elastic reset element can also be a spring sheet, a tension spring, etc. The two ends of the spring sheet or tension spring are respectively connected to the clamping plate 5 and the base. When the target block 3 is inserted between the clamping plate 5 and the base, the spring sheet or tension spring provides the clamping plate 5 with the force required to hold the target block 3.

[0032] The base includes a central vertical plate 9, side vertical plates 10, and a horizontal plate 11. The central vertical plate 9 extends to the side opposite to the clamping plate 5 to form the side vertical plate 10. The side vertical plate 10 is detachably connected to the fixing plate 4 by fasteners. Preferably, the side vertical plate 10 is connected to the fixing plate 4 by screws 17. The central vertical plate 9 and the fixing plate 4 are spaced apart and opposite to each other, and the two cooperate to clamp the external ultrasound probe 2.

[0033] A horizontal plate 11 extends from the side of the central vertical plate 9 near the clamping plate 5. Two first pivot seats 13 are provided on the horizontal plate 11, and two second pivot seats 12 are provided on the side of the clamping plate 5 near the central vertical plate 9. A pivot 6 passes through the two first pivot seats 13 and the two second pivot seats 12. A first groove 14 is provided on the top surface of the horizontal plate 11, and a second groove 15 is provided on the side of the clamping plate 5 near the central vertical plate 9. The two ends of a torsion spring 7 are respectively fixed to the first groove 14 and the second groove 15. The target block 3 is placed between the clamping plate 5 and the central vertical plate 9 and clamped by the torsion spring 7. Pulling open the clamping plate 5 allows for quick removal of the target block 3. The positions of the first groove 14 and the second groove 15 are not limited to those shown in the figure. Preferably, the two first pivot seats 13 are connected to the central vertical plate 9, making the first pivot seats 13 more stable and robust.

[0034] The external ultrasound probe 2 includes a housing 21 and a cover plate 22. The scanning head 23, PCB board 24 and flexible flat cable 25 are installed in the cavity formed by the housing 21 and the cover plate 22. The PCB board 24 is used to control the scanning head 23, and the flexible flat cable 25 is used to connect the PCB board 24 and the power line 29.

[0035] The external ultrasound probe 2 is L-shaped, including a horizontal part 26 and a vertical detection part 27. The scanning head 23 is located in the detection part 27. The horizontal part 26 can be used as a handle for hand operation or fixed on a conventional puncture target frame.

[0036] A puncture channel 28 is provided on the outer side or in the middle of the detection section 27. The central vertical plate 9 of the puncture frame 1 is placed in the puncture channel 28. The fixing plate 4 is located outside the detection section 27 of the external ultrasound probe 2. The fixing plate 4 is locked to the side vertical plate 10 with screws. The fixing plate 4 and the central vertical plate 9 cooperate to clamp the detection section 27 of the external ultrasound probe 2. In this embodiment, the detection angle of the external ultrasound probe 2 is between 60° and 120°.

[0037] The external ultrasound probe 2 can be a single-plane scanning probe ( Figure 8 It can also be a dual-plane scanning probe ( Figure 5 The single-plane scanning probe is a convex array type with a puncture channel 28 on the outer side, and its ultrasound frequency is between 1MHz and 5MHz. The dual-plane scanning probe is a linear array type with a puncture channel 28 in the middle, and its ultrasound frequency is between 1MHz and 6MHz.

[0038] The puncture frame has a simple structure, is easy to disassemble and assemble, and is convenient for thorough cleaning. The target block is easy to install and remove, and can be powerfully cleaned. All parts of the puncture frame are reusable, with no disposable consumables, thus resulting in low operating costs.
