Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a torsion locking device and an ultrasonic knife system using the torsion locking device.
Background
The ultrasonic knife is fully called as an ultrasonic cutting hemostatic knife, and is a novel ultrasonic treatment device applied to open and endoscopic surgical operations. The ultrasonic knife converts the electric energy into mechanical energy through the transducer, and an ultrasonic system in the handle amplifies the kinetic energy on the knife bar to cut tissues. The ultrasonic hemostatic cutter mainly utilizes three effects of mechanical impact, cavitation effect and thermal effect generated by high-frequency vibration to cut tissues and stop bleeding. Compared with the common surgical knife and other energy surgical equipment, the ultrasonic cutting hemostatic cutter has the advantages of high surgical accuracy, simple and convenient operation, small surgical wound area, no smoke, small bleeding amount, short surgical time, high postoperative recovery speed and the like, and is widely applied to colorectal surgery, gastric surgery, cholecystectomy, spleen surgery, myoma excision, holohuterectomy, thyroidectomy, adrenal gland excision, prostatectomy and the like.
The main mechanical parts of the existing ultrasonic knife mainly comprise an ultrasonic transducer and a waveguide rod with a tool bit. The ultrasonic transducer converts an ultrasonic frequency electric signal generated by a main machine of the ultrasonic knife into ultrasonic frequency mechanical vibration, and transmits the mechanical wave to the waveguide rod through the front end of the ultrasonic transducer. The mechanical wave propagates along the waveguide rod, and finally, the mechanical vibration energy of ultrasonic frequency is focused on the tip of the cutter head to act on the target tissue.
Since mechanical vibrations of ultrasonic frequencies tend to produce mechanical fatigue at the tool bit with multiple geometric deformations, the waveguide rod with the tool bit is set as a disposable consumable, while the transducer is set as an instrument with a certain number of times. The two are thus separated and require assembly prior to surgical use. In order to facilitate the assembly of the ultrasonic transducer and the waveguide rod, the existing ultrasonic knife is generally provided with a torsion locking device integrally formed with the ultrasonic knife. However, since the ultrasonic blade includes a plurality of components, manufacturing errors and material properties of the components are different, the torsion locking device is easy to fail due to overlarge torsion when the ultrasonic transducer and the waveguide are assembled, so that the phenomenon that the torsion locking device cannot be replaced and only the ultrasonic blade can be replaced integrally occurs, and unnecessary cost and operation time are increased. Meanwhile, the locking device integrated with the ultrasonic knife is inconvenient for a user to apply force, so that the user is inconvenient to operate when using the ultrasonic knife, and the assembly efficiency is low.

In this embodiment, in order to ensure the connection strength between the waveguide rod 4 and the ultrasonic transducer 3 and avoid the waveguide rod 4 from falling off from the ultrasonic transducer 3 during the operation, the waveguide rod 4 is screwed to the ultrasonic transducer 3. For example, a screw hole may be provided along the axial direction of the waveguide rod 4, a screw may be provided at the output end of the ultrasonic transducer 3, and the waveguide rod 4 and the ultrasonic transducer 3 may be screwed by screwing the screw into the screw hole. Instead of a threaded connection, the waveguide rod 4 and the ultrasound transducer 3 may also be snap-fit. In addition, in order to facilitate the hand-held ultrasonic knife system, a handle 5 is sleeved on the waveguide rod 4, and a finger ring which is convenient for a finger to pass through is arranged on the handle 5.
Because the waveguide rod 4 has a smaller rod diameter, the difficulty of directly rotating the waveguide rod 4 is high, the efficiency is low, and the waveguide rod 4 is easy to damage. In order to reduce the connection difficulty of the waveguide rod 4 and the ultrasonic transducer 3, realize the quick connection of the waveguide rod 4 and the ultrasonic transducer 3, avoid the damage of the waveguide rod 4 or the ultrasonic transducer 3 during connection, the ultrasonic knife system also comprises a torsion locking device which is arranged separately with the waveguide rod 4 and the ultrasonic transducer 3. Specifically, as shown in fig. 3, the torsion locking device comprises a locking wrench 1 and a thumb wheel 2, wherein the thumb wheel 2 is fixedly connected with a waveguide rod 4. In this embodiment, connecting holes are formed in the thumb wheel 2 and the waveguide rod 4, and the thumb wheel 2 and the waveguide rod 4 are fixedly connected by inserting a plug pin 6 into the two connecting holes.
