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 an optical fiber grating sensor and a flexible ureteroscope. The optical fiber grating sensor includes: an elastic housing, a sensing head, a first mounting part, a second mounting part, a first grating for measuring axial force and A second grating for measuring lateral force; the sensing head is installed at one end of the elastic housing, the first mounting part and the second mounting part are installed in the elastic housing, and the second mounting part is located at the first Between the mounting part and the sensing head, the two ends of the first grating are installed on the sensing head and the first mounting part respectively, the first grating passes through the second mounting part, and the two ends of the second grating The ends are installed on the first mounting part and the second mounting part respectively. The fiber grating sensor can accurately detect the force at the end of the flexible ureteroscope, reducing the risk of surgery.

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...
