Description

Technical Field

[0001] This utility model relates to the field of puncture frames, specifically an adjustable transperineal puncture guide. Background Technology

[0002] Most existing perineal puncture guides are non-adjustable. After the puncture needle passes through the puncture hole of the guide, there is still a distance between the puncture needle and the skin at the perineum. The puncture needle is not supported, and it is not only unstable during the puncture process, but also difficult to align the puncture position.

[0003] Therefore, we propose an adjustable transperineal puncture guide to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an adjustable transperineal puncture guide, including a mounting base for mounting on an ultrasonic probe and a plurality of needle groove units arranged in an array. The bottom needle groove unit is slidably connected to the mounting base, and adjacent needle groove units are slidably connected to each other. Each needle groove unit is provided with a puncture hole.

[0005] Preferably, the bottom of the needle groove unit is provided with an integrally integrated slider, the top of the needle groove unit is provided with a first sliding groove that matches the slider, and adjacent needle groove units are slidably connected through the slider and the first sliding groove. The top of the mounting base is provided with second sliding grooves at equal intervals, and the slider at the bottom of the bottom needle groove unit is slidably connected in the corresponding second sliding groove. The left side of the needle groove unit is provided with a third sliding groove, and the right side of the needle groove unit is provided with a slider. Adjacent needle groove units on the left and right sides are slidably connected through the slider and the third sliding groove.

[0006] Preferably, the needle groove unit has an integrally formed sleeve on one side facing the puncture hole that contacts the skin of the perineum, and the inner wall of the sleeve coincides with the inner wall of the puncture hole.

[0007] Preferably, the end of the puncture hole away from the sleeve is provided with a countersunk head.

[0008] Preferably, the slider is stepped, and the slider is provided with an anti-detachment part. Both the first slide groove and the second slide groove are provided with an installation port.

[0009] Beneficial effects

[0010] Adjustability and flexibility: The guide, through its slidingly connected needle groove units, allows for adjustment of the position of each needle groove unit according to the patient's specific condition before puncture, ensuring that the puncture needle can be more accurately aligned with the target location. This adjustability greatly improves the accuracy and flexibility of puncture.

[0011] Improved stability: Because the needle groove unit allows for close contact with the perineal skin (through the sleeve design) and can be adjusted to accommodate different patients' perineal shapes, the puncture needle receives better support during the procedure. This reduces movement during puncture and improves stability.

[0012] Optimized puncture effect: By adjusting the position of the needle groove unit, it can be ensured that the end of each sleeve can make close contact with the skin of the perineum, thereby optimizing the puncture path, reducing puncture resistance and discomfort, and improving the puncture effect.

[0013] User comfort: The design of the sleeve not only increases the contact area with the skin but also reduces patient discomfort by decreasing the direct contact area. This design makes the puncture process more humane and improves patient comfort. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 7An adjustable transperineal puncture guide is provided. The guide mainly consists of a mounting base 1 and multiple arrayed needle groove units 2. The mounting base 1 is designed specifically for ultrasonic probes to facilitate precise positioning and operation.

[0024] The bottom needle groove unit 2 is slidably connected to the mounting base 1, and adjacent needle groove units 2 are slidably connected to each other. The needle groove unit 2 is provided with a puncture hole 3. The bottom of the needle groove unit 2 is provided with an integrally integrated slider 4. The top of the needle groove unit 2 is provided with a first sliding groove 5 that matches the slider 4. The upper and lower adjacent needle groove units 2 are slidably connected through the slider 4 and the first sliding groove 5. The top of the mounting base 1 is provided with second sliding grooves 6 at equal intervals, and the slider 4 at the bottom of the bottom needle groove unit 2 is slidably connected in the corresponding second sliding groove 6. The left side of the needle groove unit 2 is provided with a third sliding groove 11, and the right side of the needle groove unit 2 is provided with a slider 12. The left and right adjacent needle groove units 2 are slidably connected through the slider 12 and the third sliding groove 11.

[0025] The sliders 4 are uniquely designed, featuring a stepped shape and an anti-detachment part 9. This design ensures the stability of the pin groove unit 2 after installation. Both the first and second slide grooves 5 and 6 have mounting ports 10, facilitating installation and disassembly. During installation, the user simply presses the mounting port 10 on the slide groove, utilizing the deformation capability of the anti-detachment part 9 to easily slide the slider 4 into the slide groove, completing the assembly.

[0026] This design allows the needle groove units 2 to slide back and forth relative to each other, thus enabling flexible adjustments based on the patient's specific condition.

[0027] Even more thoughtfully, each needle groove unit 2 has an integrated sleeve 7 positioned on one side, directly opposite the puncture hole 3. This sleeve 7 is designed to perfectly overlap with the inner wall of the puncture hole 3, and its relatively small contact area makes it more comfortable when in contact with the perineal skin, reducing patient discomfort. During the puncture, simply press the sleeve 7 gently against the perineal skin; due to the flexible sliding between the needle groove units 2, the end of the sleeve 7 can perfectly adapt to various perineal shapes, ensuring optimal puncture results.

[0028] Furthermore, to facilitate the guidance of the puncture needle, a countersunk head 8 is cleverly provided at the end of each puncture hole 3 furthest from the sleeve 7. This design not only improves the accuracy of the puncture but also makes the entire puncture process smoother and more efficient.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
