Abstract

The utility model relates to a medical infrared direction meter for internal urethrotomy, which comprises an infrared generating and receiving circuit device, a control switch, an infrared transmitter, an infrared receiver and a display screen, wherein the infrared transmitter is composed of an outer tube, a convex lens, an infrared luminous tube and a connecting rod, and the infrared receiver is composed of an outer tube, an inner tube, a shielding tube, a shielding umbrella and an infrared receiving tube. During operations, the control switch is turned on, the infrared transmitter sends out parallel beams, after the infrared receiver inducts the beams, the beams are converted into electric signals to be displayed on the display screen, and a doctor can adjust the positions of the infrared receiver and an operation knife to operate according to display.

Description

A kind of medical internal urethrotomy infrared ray position finder

This utility model relates to surgical medical equipment.

Treating at present urethral stricture or atresia operation method commonly used clinically is the row internal urethrotomy, but, using the urethrostenosis or urethratresia atresia of urethra, particularly dislocation takes place and during out of line atresia of urethra in the broken ends of fractured bone of locking urethra, the problem that surgical doctor feels a delicacy about is can not be accurately directed, generally can only lean on the high light transillumination now, finger touch, methods such as seal wire guiding are carried out rough orientation.

The purpose of this utility model provides a kind of infrared ray position finder, utilizes RF transmitter to send collimated light beam, receives the location by infrared receiver, demonstrates accurate position on display screen, and the doctor can calibrate scalpel according to display position and undergo surgery.

This utility model is realized by following scheme: it includes infrared ray and takes place, receive parts such as electrical installation and gauge tap, it also includes RF transmitter, infrared receiver and display screen, RF transmitter is by outer tube, convex lens, infrared light emission pipe and connecting rod are formed, convex lens is contained in the front end of outer tube, in convex lens back focus fixed-site the infrared light emission pipe is arranged, connecting rod is contained in the rear portion of outer tube, power line is connected with the infrared light emission pipe by connecting rod, infrared receiver is by outer tube, fixed several infrared shield pipes of annular equidistant arrangement are formed between interior pipe and inner and outer pipes, infrared receiver tube and shielding umbrella are housed in the infrared shield pipe, infrared receiver tube is loaded on the shielded-plate tube rear portion, conical shielding umbrella is housed in the front portion of infrared receiver tube, on the end face of infrared receiver afterbody, be carved with the mark of this infrared receiver position of expression, display screen is made up of display panel and light emitting diode, with the same number of Light-Emitting Diode of infrared receiver tube by the correspondingly equidistant annular array in the residing position of homologous lines receiving tube, the residing position of the infrared receiver tube that is connected separately on display panel.During operation RF transmitter is inserted the proximal end of internal urethral orifice to the urethra broken ends of fractured bone through the bladder stoma mouth, infrared receiver per urethra collar extension is put into the distal end portion of the urethra broken ends of fractured bone, open gauge tap, RF transmitter sends the flat fire light beam, infrared receiver is sensed the relative position that changes the signal of telecommunication behind the light beam and demonstrate the urethra broken ends of fractured bone on display screen, the position of adjusting infrared receiver and scalpel according to the shows signal of display screen undergos surgery, for operation provides safety guarantee.
