Description

Technical Field

[0001] The utility model relates to the field of adjusting devices, in particular to a fixing and adjusting device for a prostate puncture ultrasound probe. Background Art

[0002] Puncture surgery is generally used for biopsy of diseased tissue, ablation treatment, etc. It belongs to the field of minimally invasive surgery. It is a common minimally invasive surgical procedure in clinical practice. Under the guidance of medical imaging, the doctor punctures the puncture needle through the skin to the lesion area to establish a channel for biopsy or interventional treatment. It has the characteristics of less trauma, less pain, and faster recovery. At the same time, it also places high demands on the accuracy, stability and skills of the surgical operation.

[0003] At present, traditional puncture surgical equipment is usually a handheld ultrasound probe device, some of which are equipped with a universal cantilever, which can adjust and rotate the ultrasound probe within a certain range. This has certain advantages, but there are also problems such as the inability to hover at any position and the weight of the equipment needs to be borne entirely by the user. This places high demands on the user's physical and mental strength. At the same time, during the puncture surgery, the doctor usually needs to perform ultrasound scanning and parameter adjustment while holding the biopsy puncture needle in hand to insert it into the lesion site. The operation is cumbersome and inefficient.

[0004] In addition, the connection between the ultrasonic probe of traditional puncture surgical probe equipment and other components of the equipment mostly uses hand-tightened screws, which is not only inconvenient to install, but also has the risk of scratching the patient. At the same time, the space required for adjusting the universal cantilever is large, and the rotating part cannot perform radial displacement adjustment, so micro-adjustment cannot be achieved.

[0030] The applicant believes that existing prostate puncture ultrasound probes are difficult to operate by a single person. Furthermore, conventional puncture surgical probes present several challenges. For example, the ultrasound probe and rotating base, among other components, are often mounted using hand-tightened screws, which is not only inconvenient but also poses a risk of scratching the patient. When using a universal cantilever for adjustment, the weight of the mechanism itself must be borne entirely by the doctor's hand, resulting in a high workload. Conventional devices cannot be hovered during any adjustment, requiring the doctor to hold the mechanism in place, making operation inconvenient, time-consuming, and labor-intensive.

The probe can also be adjusted 360 degrees and hovered at any position through the cooperation of the universal ball head nut 405 and the deflection spring 406. At the same time, the rotation fixing seat 501 is connected to the probe rotation fixing mechanism 1 using a bayonet method, that is, the two components can be connected by just pressing once, which has the advantages of easy disassembly and assembly and simple operation.

[0040] like Figure 2-Figure 4 As shown, the probe rotation and fixing mechanism 1 includes a rotation seat 101 , a rotation limiting seat 105 , a rotation mounting seat 102 , a probe locking nut 104 and a wire fixing seat 103 .
