Intracavity probe cover

Technical field

The invention relates to the technical field of medical supplies, in particular to a double-layer water-fillable intracavity probe cover.

Background technique

Currently, prostate biopsy is generally divided into two types: transrectal puncture and transperineal puncture. Transrectal puncture requires enema preparation, and puncture at the lithotomy position is painful and risky for patients; transperineal prostate puncture is guided by an ultrasound probe, and the biopsy needle is punctured directly into the external prostate through the soft tissue of the perineum. Tissue cutting can specifically target the outer or inner glands for multiple times, avoiding intestinal injury, less pain and fewer complications.

When performing puncture operations, an intracavity ultrasound probe is needed. The ultrasound probe is placed in the human body, and image information is obtained by using the ultrasound probe. Medical staff locate the puncture position according to the image information to ensure that the puncture is in the correct position. However, due to the limitation of the range of movement of the intracavitary ultrasound probe, it is often impossible to locate the prostate in the best position, and thus the best ultrasound image cannot be obtained, and positioning deviation may occur, which may affect the accuracy of the test in severe cases.

detailed description

The following describes exemplary embodiments of the present invention with reference to the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and should be regarded as merely exemplary. Therefore, those of ordinary skill in the art should realize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Likewise, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

As shown in Figure 1-4, an intracavity probe cover includes a sleeve and a water injection pipe. The front port of the sleeve is closed, the rear port is an insertion port, and the sleeve includes an arched top surface 1 and a horizontal形的底面2;

The top surface 1 includes two superimposed films, the edges of the two films are sealed to form a water storage cavity between the two films, and the water storage cavity is connected to the water injection pipe 3.

The traditional probe cover cannot achieve contour expansion. When the image quality obtained by the intracavity probe is low, effective adjustment cannot be made due to the limited movement range of the head in the cavity. The intracavity probe cover provided by this embodiment is a disposable product, and has the advantages of safety and sanitation of the existing probe cover and avoiding cross-infection; in addition, it can also inject water into the water storage cavity during ultrasonic testing to make the cavity The contour of the inner probe cover expands outward. Take perineal prostatic puncture as an example. If the quality of the image acquired by the intracavitary probe is low, water can be injected into the water storage cavity. The intracavity probe cover expands and squeezes the prostate, thereby adjusting the prostate Position, the water storage cavity expands upward after water is injected. For example, the expansion range of the water storage cavity is 0-5mm. After the expansion of the water storage cavity, the prostate can be positioned to the best focal length, and the ultrasound image can be enhanced to achieve precise positioning.

As a preferred implementation of this embodiment, in order to optimize the structure of the product, the front end of the top surface 1 is in a hemispherical shape for closing the front port of the sleeve. The top surface 1 tends to have a smooth shape as a whole, with no edges or corners on it, which minimizes patient discomfort. The bottom surface 2 includes two superimposed films. The edges of the two films are sealed to form a accommodating cavity between the two films. The accommodating cavity is provided with a supporting plate arranged along the axial direction of the sleeve. The supporting plate is arranged on the bottom surface 2 and used for supporting the bottom surface 2 to ensure that it maintains a sleeve-like structure; further, the supporting plate may be an arc-shaped plate, that is, its cross-section is an arc. The curved surface of the curved plate is used to fit the probe in the cavity.
