1-3 , which are preferred embodiments of the present invention.

The dual-probe handheld ultrasonic diagnostic instrument includes a body 101, wherein a host for wireless communication with an external display terminal is arranged inside the body 101. The host serves as a control center and can process data, etc. A convex array probe 201 and a linear array probe 301 are arranged at both ends of the body 101, respectively. The convex array probe 201 is used for ultrasonic scanning of the abdomen, heart, and small organs, etc., and the linear array probe 301 is used for ultrasonic scanning of the body surface and blood vessels, etc. The convex array probe 201 and the linear array probe 301 are electrically connected to the host, respectively. The data scanned by the convex array probe 201 and the linear array probe 301 are directly transmitted to the host for processing, and then transmitted by the host to the display terminal for display.

The body 101 is flat, and two sides of the body 101 form a gripping side 102 for a user to grip. Along the direction from the end to the middle of the body 101, the gripping side 102 is curved inwardly in an arc shape.

The dual-probe handheld ultrasound diagnostic instrument provided above has a convex array probe 201 and a linear array probe 301 arranged on the body 101, which can meet the needs of ultrasound scanning of different parts to be scanned; a host is arranged in the body 101, and the data of ultrasound scanning by the convex array probe 201 and the linear array probe 301 can be processed in the host, and then transmitted to the display terminal for display via wireless communication, which is easy to use.

The convex array probe 201 has a convex array end surface 202 that abuts against the scanning part. Along the extension direction between the two hand-holding sides 102 of the body 101, the convex array end surface 202 is a curved surface with the middle portion protruding outward.

The end of the body 101 is provided with a detachable convex array shell, and a convex array end face 202 is formed on the convex array shell; a plurality of concave longitudinal notches 203 and a plurality of concave transverse notches 204 are provided on the convex array end face 202, and the longitudinal notches 203 and the transverse notches 204 respectively pass through the edges of the convex array end face 202; the plurality of longitudinal notches 203 and the transverse notches 204 are respectively staggered and connected and arranged in a grid shape on the convex array end face 202.

Since the probe needs to apply coupling agent on the part to be scanned when performing ultrasonic scanning, the coupling agent is often squeezed and thinned during the movement of the probe. In this way, the coupling agent needs to be repeatedly applied, which is cumbersome. By providing the transverse notches 204 and the longitudinal notches 203 arranged in a grid shape on the convex array end face 202, the coupling agent will be embedded in the transverse notches 204 and the longitudinal notches 203 during the movement of the convex array end face 202 against the human body. Since the transverse notches 204 and the longitudinal notches 203 pass through the edge of the convex array end face 202, the convex array end face 202 will not completely squeeze the coupling agent and thin it, and the coupling agent will continue to be embedded in the transverse notches 204 and the longitudinal notches 203, thereby improving the accuracy of ultrasonic scanning.

A lateral swing plate is provided at the end of the body 101, and the lateral swing plate swings up and down along the bending direction of the convex array end surface 202 with the middle thereof as the swing center; the convex array shell is sleeved on the outer periphery of the lateral swing plate and is engaged and connected with the lateral swing plate.

In this way, after the convex array end face 202 abuts against the part to be scanned, during the squeezing movement, the lateral swing plate can swing up and down along the bending direction of the convex array end face 202, and then the convex array end face 202 can swing, so that the convex array end face 202 can abut against a larger area of the part to be scanned, thereby greatly improving the accuracy of ultrasonic scanning.

The outer periphery of the end of the body 101 is provided with a first step ring facing the convex array shell and arranged around the outer periphery of the body 101, and the first step ring is covered with a first elastic layer; the bottom of the convex array shell has a convex array abutment surface arranged facing the first step ring, and the convex array abutment surface is fixedly abutted on the first elastic layer.

The first elastic layer can limit and position the swing of the convex array shell, and when there is no resisting pressure, the convex array shell is driven to automatically reset.

Along the direction from the convex array abutting surface to the first step ring, the thickness of the first elastic layer gradually increases, thereby strengthening the function of the first elastic layer in driving the convex array housing to reset.

The linear array probe 301 has a linear array end face 302 that abuts the scanning part. The linear array end face 302 is flat along the extension direction between the two hand-holding sides 102 of the body 101. An arc-shaped convex strip 303 is protruded from the middle of the linear array end face 302, and the arc-shaped convex strip 303 is extended between the two hand-holding sides 102 of the body 101.

A detachable linear array shell is provided at the end of the body 101 , and a linear array end face 302 is formed on the linear array shell; a plurality of recessed guide notches 304 are provided on the arc-shaped convex strip 303 , and the guide notches 304 are arranged to bend and extend along the width direction of the arc-shaped convex strip 303 and pass through the edge of the arc-shaped convex strip 303 .

In this way, when the linear array end surface 302 abuts against the part to be scanned, and in the process of pushing the linear array end surface 302 to move, the coupling agent is prevented from being completely squeezed out and thinned, and the coupling agent can be embedded in the guide notch 304 to ensure the accuracy of ultrasonic scanning.

Two end side surfaces are formed on the body 101 between the two hand-holding sides 102 and are arranged opposite to each other; the end of the body 101 has an end swing plate, which swings up and down between the two end side surfaces with the middle thereof as the swing center; the convex array shell is sleeved on the outer periphery of the end swing plate and is engaged and connected with the end swing plate.

In this way, after the linear array end face 302 abuts against the part to be scanned, during the extrusion movement, the end swing plate can swing up and down between the two end sides, and then the linear array end face 302 can swing, so that the linear array end face 302 can abut against a larger area of the part to be scanned, thereby greatly improving the accuracy of ultrasonic scanning.

The outer periphery of the end of the body 101 is provided with a second step ring facing the linear array shell and arranged around the outer periphery of the body 101, and the second step ring is laid with a second elastic layer; the bottom of the linear array shell has a linear array abutment surface arranged facing the second step ring, and the linear array abutment surface is fixedly abutted on the second elastic layer.

The second elastic layer can limit and position the swing of the linear array housing, and when there is no resisting pressure, the linear array housing is driven to automatically reset.

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.
