Description

Technical Field

[0001] The utility model relates to the field of medical equipment, and more specifically to a detachable superficial lesion ultrasonic body surface positioning device and an ultrasonic probe. Background Art

[0002] For surgical operations on superficial lesions, the current goal is to completely remove the lesions while minimizing the number of surgical incisions. This requires ultrasound doctors to accurately locate the lesions before surgery, especially for those lesions that are located deeper and cannot be detected by surgical palpation.

[0003] At present, ultrasound doctors usually use the following method to locate superficial lesions: move the probe to the edge of the lesion, then press the center of the probe with a finger, then remove the probe and mark the pressed position on the body surface with a pen;

[0004] During such an operation, the probe exerts pressure on the skin and subcutaneous tissue during the examination, or causes the lesion to shift. When the probe is removed, the squeezing disappears, and the positional relationship between the skin surface and the deep lesion changes, resulting in a difference between the lesion edge location and the actual location. In addition, finger pressure positioning is not accurate enough for smaller positioning because the finger contact area is large and the skin cannot be pressed accurately vertically. This will lead to an increase in the surgical incision and worsening of the patient's injury. Utility Model Content

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] First embodiment:

[0025] A detachable superficial lesion ultrasonic body surface positioning device, such as Figure 1 As shown, it includes a telescopic clamp 1, which is detachably connected to the side wall of the ultrasonic probe 8. A sleeve 2 is provided on the telescopic clamp 1, and a pressing pen 3 is detachably connected inside the sleeve 2. The pressing pen 3 is an existing press-type gel pen on the market. When pressed, the pen tip is exposed for marking and positioning, and can be retracted into the device by pressing again, without affecting the scanning of the ultrasonic probe 8.

[0026] like Figure 2 and Figure 3 As shown, the telescopic clamp 1 includes a fixed tube 101, which is arranged in the horizontal direction. Sliding grooves 4 are provided at both ends of the fixed tube 101. The sliding grooves 4 are provided along the length direction of the fixed tube 101. A clamping claw 102 is slidably arranged in the sliding groove 4. A spring 5 is also arranged in the sliding groove 4. One end of the spring 5 is connected to the bottom of the sliding groove 4, and the other end is connected to the clamping claw 102. The clamping claws 102 are respectively abutted against the two sides of the ultrasonic probe 8. Under the rebound action of the spring 5, the device is clamped on the ultrasonic probe 8 by the clamping claws 102 to achieve fixation. The elastic force of the two springs 5 ​​is the same. The fixed tube 101 will be located in the middle of the ultrasonic probe 8. The telescopic clamp 1 can adapt to ultrasonic probes 8 of different widths.

[0027] The two ends of the spring 5 can be fixed by glue or welding, or a tension spring with barbs at both ends is used, and the clamping jaw 102 is fixed by the spring 5 to prevent it from falling off.
