Description
Technical field
The invention belongs to medical instruments field, relate to one and organize and blood be applicable to human body surgery and Minimally Invasive Surgery
The blood coagulation of pipe and a kind of ultrasound knife system of cutting.
Background technology
Modern medicine development is swift and violent, and ultrasound knife is widely used in clinical surgery operation, and ultrasound knife is to utilize high energy to surpass
Acoustic cavitation effect makes tumor tissue cell's film rupture, and high-energy ultrasound is released huge energy and is quickly converted to heat energy simultaneously, can picture
The same blood coagulation of true cutter or cutting inside of human body tissue or the ultrasound wave of blood vessel.
The ultrasound knife used in the market is by main frame, shaft portion, handle portion, transducer portion and torque spanner portion
Being grouped into, shaft portion and transducer portion are Split type structure, and both are to be connected by nipple, first will when operation uses
Both get up, in succession in order to protect nonexpondable transducer and ultrasonic knife bar, shaft portion and transducer portion to be by having
Limiter amount is threaded, and this connects strength and is completed by adnexa torque spanner.Doctor is before surgery, it is necessary to first connect ultrasonic knife bar
And transducer, torque spanner passes knife bar, inserts in the endoporus of rotary handle, and one holds transducer, and one holds torsion pulls
Hands, is controlled knife bar and the threaded strength of transducer by torque spanner.Operate and inconvenience.
Doctor forgets to use this torque spanner sometimes, and direct one holds knife bar, and one holds transducer, down to knife bar and
Transducer connects loosely, affects ultrasound knife serviceability, or it is too quickly to connect strength, twists into two parts ultrasonic knife bar or transducer.Every time
Operation consent will repeat the assembling again between apparatus, has delayed operating time.And torque spanner is easy to lose de-, makes
Become to pollute, it is impossible to using, cause ultrasound knife knife bar and transducer not to connect, ultrasound knife cannot work.
It addition, existing product is in use, case position arranges unreasonable, causes using for a long time, forefinger numbness and uncomfortableness,
Inconvenience is brought to operation.
Summary of the invention
The deficiencies in the prior art in view of the above, the present invention provides a kind of ultrasound knife system, when using ultrasound knife operation,
