Problems solved by technology

It also often causes the wires at the solder joint between the transducer and the cable to fall off or break, making it impossible to use normally
Although only the cable is damaged, the transducer and the cable must be sent together for repair, which is costly and delays the operation time

Abstract

The invention discloses an ultrasonic transducer separable slip-ring type cable comprising a front cover, a main shell, a piezoelectric transducer chip and a cable body, wherein the front end of the front cover is provided with an inner ring electrode and an outer ring electrode; the cable body is composed of an insulating tube and four electric wires arranged inside the insulating tube; a live line of a power supply is connected with the anode of the piezoelectric transducer chip, and a zero line of the power supply is connected with the cathode of the piezoelectric transducer chip; and a control signal anode line is connected with the inner ring electrode, and a control signal cathode line is connected with the outer ring electrode. The ultrasonic transducer separable slip-ring type cable is improved in that middles of all the electric wires in the cable body are connected in a plugging way of slip-ring sockets and slip-ring plugs, and the slip-ring sockets and the slip-ring plugs can circumferentially rotate; and the slip-ring sockets can be fixedly connected with the rear end of the main shell. The ultrasonic transducer separable slip-ring type cable has the main purposes and advantage that the cable body cannot be wound in the process that a surgical operator precisely and conveniently finishes a surgery through repeatedly regulating a control knob. The ultrasonic transducer separable slip-ring type cable is also very simple in mounting and dismounting, and the maintenance costs of a transducer and the cable body are reduced.

Description

technical field [0001] The invention relates to the technical field of medical surgical instrument ultrasonic knife, in particular to a detachable sliding ring cable for an ultrasonic transducer. Background technique [0002] Ultrasonic knife is the necessary surgical equipment for laparoscopic technology. By converting electrical energy into mechanical energy, no current passes through the patient's body. It can cut and coagulate at the same time, and it integrates cutting, coagulation, grasping and separation. The cutting speed is fast, the hemostatic effect is good, the operation is simple, safe and convenient, which can greatly shorten the operation time, reduce the blood loss and blood transfusion of patients, thereby reducing complications and operation costs. Ultrasonic knife is mostly used in fine surgical operations, and more and more used in various endoscopic operations, such as: laparoscopy, prostatectomy, cystoscopy, hysteroscopy and other operations, in lapa...
