Abstract

The present disclosure relates to an ultrasonic probe used in a medical instrument for ultrasonic diagnosis, and the ultrasonic probe includes a strain relief having a structure for preventing a cable from being damaged by twisting or sharp bending.

First claim

1 . An ultrasonic probe comprising:
a case to accommodate an ultrasonic transceiver; a cable to connect the ultrasonic transceiver and a main body of a medical instrument; and a strain relief provided outside the case to prevent breakage of the cable, wherein the strain relief is formed in a truncated conical shape and includes a passage through which the cable is capable of passing, and the strain relief includes portions having at least two truncated conical shapes divided perpendicular to a central axis of the strain relief.

2 . The ultrasonic probe according to claim 1 ,
wherein two adjacent portions among the portions having the at least two truncated conical shapes of the strain relief are rotatable with respect to each other at a predetermined angle.

3 . The ultrasonic probe according to claim 1 ,
wherein a portion having a fixed end of the strain relief among the portions having the at least two truncated conical shapes of the strain relief is rotatable with respect to the case at a predetermined angle.

4 . The ultrasonic probe according to claim 2 ,
wherein when a free end of the strain relief is rotated by more than the predetermined angle, a torsional force is first applied to a portion adjacent to the free end among the two adjacent portions, and a torsional force is later applied to a portion adjacent to a fixed end of the strain relief among the two adjacent portions.

5 . The ultrasonic probe according to claim 1 ,
wherein when a free end of the strain relief is rotated, a torsional force is first applied to a portion adjacent to the free end among the portions having the at least two truncated conical shapes, and a torsional force is later applied to a portion adjacent to a fixed end of the strain relief.

6 . The ultrasonic probe according to claim 1 ,
wherein the passage is provided asymmetrically inside the strain relief so that the strain relief is capable of being bent to one side.

7 . The ultrasonic probe according to claim 6 ,
wherein an end of the passage on a fixed end side of the strain relief is provided to deviate from a center of the strain relief.

8 . The ultrasonic probe according to claim 6 ,
wherein the passage is provided such that a central axis of the passage is spaced from a central axis of the strain relief by a certain distance.

9 . The ultrasonic probe according to claim 1 ,
wherein the passage includes a plurality of recesses provided on a side wall of the passage so that the strain relief is bent in multiple steps.

10 . The ultrasonic probe according to claim 1 ,
wherein the strain relief includes a reinforcing member provided at one side of the passage so that the strain relief is capable of being bent to one side.

11 . An ultrasonic probe comprising:
a case to accommodate an ultrasonic transceiver; a cable to connect the ultrasonic transceiver and a main body of a medical instrument; and a strain relief provided outside the case to prevent breakage of the cable, wherein the strain relief includes a passage through which the cable is capable of passing, and a reinforcing member provided at one side of the passage so that the strain relief is capable of being bent to one side.

12 . The ultrasonic probe according to claim 11 ,
wherein the strain relief is formed in a truncated conical shape, and the strain relief includes portions having at least two truncated conical shapes divided perpendicular to a central axis of the strain relief.

13 . The ultrasonic probe according to claim 12 ,
wherein two adjacent portions among the portions having the at least two truncated conical shapes of the strain relief are rotatable with respect to each other at a predetermined angle.

14 . The ultrasonic probe according to claim 12 ,
wherein a portion having a fixed end of the strain relief among the portions having the at least two truncated conical shapes of the strain relief is rotatable with respect to the case at a predetermined angle.

15 . The ultrasonic probe according to claim 13 ,
wherein when a free end of the strain relief is rotated by more than the predetermined angle, a torsional force is first applied to a portion adjacent to the free end among the two adjacent portions, and a torsional force is later applied to a portion adjacent to a fixed end of the strain relief among the two adjacent portions.
