Description

Technical Field

[0001] The utility model belongs to the technical field of intracavitary probes, and more specifically, relates to a short intracavitary probe suitable for cranial surgery. Background Art

[0002] The use of intraoperative ultrasound guidance during intracranial tumor resection can accurately locate the lesion in real time, assist in determining the tumor's physical properties, clarify its boundaries, and provide evidence for tumor perfusion and differentiation between benign and malignant tumors. The use of intraoperative ultrasound has, to a certain extent, improved the resection rate of brain tumors, thereby improving prognosis.

[0003] Based on the above, the inventors have discovered the following problems: the probes commonly used in cranial surgery are mostly convex array or micro-convex array probes. Due to the size of the bone flap and the depth of the surgical cavity after bone flap removal, sometimes the probe cannot contact the brain tissue through the bone flap opening, resulting in incomplete imaging or even no imaging.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a short intracavitary probe suitable for cranial surgery is provided, in order to achieve the purpose of having more practical value. Utility Model Content

Then, the rotating member is rotated, and the rotation of the rotating member through the inclined thread groove can drive the connection port to contract, thereby fixing the extension rod. Then, the surface of the extension rod is covered with a sterilization sleeve, and then it is placed in the surgical cavity for imaging. Through the above design, the length of the extension rod can be quickly adjusted, thereby facilitating the probe to contact brain tissue for imaging.
