[0023] Reference Figure 1-3 The figure shows a preferred embodiment of the present invention.

[0024] Wireless dual-plane intracavitary ultrasound diagnostic instrument is used for ultrasound scanning in the cavity, such as rectal biopsy, or prostate scan in urology, or perineal prostate puncture for pathology, etc.

[0025] The wireless dual-plane intracavitary ultrasonic diagnostic instrument includes a body 100 for a doctor to hold. The front part of the body 100 extends forward to form an insertion section 101 inserted into the cavity. The insertion section 101 is in the shape of a round rod. When intracavitary scanning is required, the doctor directly holds the body 100 and inserts the insertion section 101 into the cavity.

[0026] A control panel is provided in the body 100. The control panel has a wireless communication component for wireless communication with the outside. The control panel serves as the control center of the entire ultrasonic diagnostic instrument. The control panel receives data and transmits the data wirelessly to an external mobile terminal or control center.

[0027] The front end of the insertion section 101 has a spherical front end head 102. A convex array probe 301 and a linear array probe 302 are provided on the front part of the insertion section 101. The convex array probe 301 is arranged around the outer periphery of the insertion section 101, and the linear array probe 302 is arranged along the axial extension of the insertion section 101. The convex array probe 301 and the linear array probe 302 are electrically connected to the control board respectively, and the outer surface of the insertion section 101 is exposed. Along the axial direction of the insertion section 101, the convex array probe 301 is arranged between the front end head 102 and the linear array probe 302.

[0028] The wireless dual-plane intracavitary ultrasonic diagnostic instrument provided above can perform ultrasonic scanning in the cavity using the convex array probe 301 and the linear array probe 302 after the insertion section 101 is inserted into the cavity. The convex array probe 301 is arranged in a circular shape, and the linear array probe 302 is arranged axially along the insertion section 101. In this way, ultrasonic scanning in multiple axial and circumferential positions can be achieved with high scanning accuracy.

[0029] The outer periphery of the rear portion of the insertion section 101 is sleeved with a rubber ring 202 that moves along the insertion section 101 , and the outer periphery of the rubber ring 202 extends outward to form an elastic annular sheet 200 ; when the insertion section 101 is inserted into the cavity, the annular sheet 200 abuts against the skin outside the cavity.

[0030] When performing intracavitary scanning, as the insertion depth of the insertion section 101 increases, the annular sheet 200 moves backward along the insertion section 101. When the insertion section 101 reaches the position, the annular sheet 200 covers the skin. In this way, the annular sheet 200 can play a shielding role to prevent some gases in the cavity from directly spraying outward, and play a positioning role. When the doctor's hand leaves the body 100, the insertion section 101 may slide outward. In this way, when the doctor holds the body 100 again, the insertion depth of the insertion section 101 can be located according to the position of the annular sheet 200.

[0031] The annular sheet 200 is arranged to tilt forward along the outward extension direction of the adhesive ring 202. In this way, when the insertion section 101 reaches the position, the doctor can press the annular sheet 200 with his hand to deform the annular sheet 200 and bend and tilt backward.

[0032] The inner ring surface of the rubber ring 202 is sleeved on the outer circumference of the insertion section 101, and the inner ring surface of the annular sheet 200 is butted against the outer ring surface of the rubber ring 202; the outer ring surface of the rubber ring 202 is provided with a plurality of elastic sheets 203 extending forward, and the plurality of elastic sheets 203 are arranged at intervals in the circumferential direction of the rubber ring 202; along the direction from back to front of the insertion section 101, the outer end of the elastic sheet 203 is inclined toward the outer circumference of the insertion section 101, and the outer end of the elastic sheet 203 abuts against the outer circumference of the insertion section 101.

[0033] By setting the elastic sheet 203, the elastic sheet 203 is arranged obliquely toward the insertion section 101 along the forward direction of the insertion section 101, so that when the annular sheet 200 moves backward along the insertion section 101, the elastic sheet 203 will not be aligned and move to cause restriction. When the annular sheet 200 needs to be moved forward along the insertion section 101, the movement of the annular sheet 200 will be restricted due to the abutment restriction of the elastic sheet 203. In this way, when the annular sheet 200 moves to the set position for positioning, when the insertion section 101 slips outward, the annular sheet 200 will not move forward, thereby ensuring its stable position.

[0034] The outer ring surface of the rubber ring 202 is provided with an operating ring 201 extending backwards. The operating ring 201 surrounds the outside of the insertion section 101 , and a deformation gap is provided between the operating ring 201 and the outer periphery of the insertion section 101 .

[0035] When the intracavitary ultrasonic diagnostic instrument is finished using, or when the annular sheet 200 needs to be moved forward along the insertion section 101, the operating ring 201 can be pressed downward to deform. Since the operating ring 201 is connected to the outer surface of the rubber ring 202, the compressed deformation of the operating ring 201 will pull the rubber ring 202 to deform. The deformation of the rubber ring 202 pulls the elastic sheet 203 away from the insertion section 101 and swings outward, so that the elastic sheet 203 is separated from the abutment against the insertion section 101, thereby facilitating the rubber ring 202 to move forward.

[0036] The outer end of the elastic sheet 203 extends horizontally toward the axial direction of the insertion section 101 to form an abutting sheet 204 abutting against the outer periphery of the insertion section 101. The abutting sheet 204 is in the shape of an arc sheet. By providing the horizontally extending abutting sheet 204, the abutting area between the elastic sheet 203 and the outer periphery of the insertion section 101 is increased, and the abutting sheet 204 can guide the movement of the rubber ring 202 during its movement.

[0037] A metal ring piece 400 is embedded inside the rubber ring 202, and the metal ring piece 400 is arranged around the outer periphery of the insertion section 101; a plurality of front pieces 401 arranged at intervals extend forward from the front end of the metal ring piece 400, and the plurality of front pieces 401 are arranged around the outside of the insertion section 101; the plurality of front pieces 401 are aligned with the plurality of elastic pieces 203, and the front pieces 401 are embedded in the elastic pieces 203; the front pieces 401 and the metal ring piece 400 are bent.

[0038] When the squeezing operation ring 201 is deformed, the rubber ring 202 is deformed, and as the metal ring piece 400 is squeezed, the front piece 401 also rises, so that the front piece 401 can pull the elastic piece 203 to rise and break away from the abutment against the insertion section 101.

[0039] The rear end of the metal ring piece 400 extends backward to form a plurality of spaced rear edge pieces 402, which are arranged around the outside of the insertion section 101; the rear edge pieces 402 are embedded in the operating ring 201. Thus, when the operating section is squeezed, the rear edge pieces 402 are also compressed and deformed, and the metal ring piece 400 is deformed accordingly, thereby causing the front edge piece 401 to deform.

[0040] Of course, the elastic deformations of the front edge piece 401, the metal ring piece 400 and the rear edge piece 402 are all elastic deformations, and they will return to their original state when the external force is eliminated.

[0041] The rear edge piece 402 and the metal ring piece 400 are bent to facilitate the elastic deformation of the metal ring piece 400 by the rear edge piece 402 .

[0042] An annular groove is provided in the middle of the insertion section 101 for the outer end of the elastic sheet 203 to be embedded in. In this way, when the intracavitary ultrasonic diagnostic instrument is not needed, the annular sheet 200 can be moved to the middle of the insertion section 101, and the elastic sheet 203 can be abutted against the annular groove to achieve the middle positioning of the annular sheet 200.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
