Problems solved by technology

During this process, the end of the flexible mirror will touch human tissue. If the operator manipulates the flexible mirror with too much force, it will cause damage to human tissue or even perforation
At present, the operation lacks the participation of the sense of touch, and the interaction force between the end of the flexible mirror and the tissue cannot be obtained, which brings risks to the operation

Abstract

The invention discloses a fiber bragg grating sensor and a flexible ureteroscope. The fiber bragg grating sensor comprises an elastic shell, a sensing head, a first mounting piece, a second mounting piece, a first optical grating used for measuring axial force and a second optical grating used for measuring transverse force. The sensing head is mounted at one end of the elastic shell; the first mounting piece and the second mounting piece are both installed in the elastic shell; the second mounting piece is located between the first mounting piece and the sensing head; the two ends of the first optical grating are installed on the sensing head and the first mounting piece respectively; the first optical grating penetrates through the second mounting piece; and the two ends of the second optical grating are installed on the first mounting piece and the second mounting piece respectively. The fiber bragg grating sensor can accurately detect the acting force at the tail end of the flexible ureteroscope and reduce the operation risk.

Description

technical field [0001] The invention relates to the field of urinary diseases, in particular to an optical fiber grating sensor and a flexible ureteroscope. Background technique [0002] In the field of urology, flexible ureteroscopic surgery has high application value. The flexible ureteroscope is inserted into the patient's urethra, from the urethra up to the bladder, then to the ureter, then along the natural bend of the ureter, and finally into the renal pelvis, first to observe the renal pelvis and then to observe each group of calyces from top to bottom. During this process, the end of the flexible mirror will touch human tissue. If the operator manipulates the flexible mirror with too much force, it will cause damage to human tissue or even perforation. At present, the operation lacks the participation of the sense of touch, and the interaction force between the end of the flexible scope and the tissue cannot be obtained, which brings risks to the operation. Conten...
