Description
Technical field
This utility model belongs to medical instruments field, is related to one kind and organizes suitable for human body surgery and Minimally Invasive Surgery
Blood coagulation with blood vessel and the ultrasound knife of cutting, specifically a kind of ultrasound knife torsion integration knob and are provided with the ultrasound of the knob
Knife.
Background technology
Modern medicine development is swift and violent, and ultrasound knife is widely used in clinical surgery operation, and ultrasound knife is super using high energy
Acoustic cavitation effect makes tumor tissue cell's film rupture, while high-energy ultrasound releases huge energy is quickly converted to heat energy, can picture
The same blood coagulation of true knife or the ultrasound wave of cutting inside of human body tissue or blood vessel.
Ultrasound knife currently used in the market is by main frame, shaft portion, handle portion, transducer portion and torque spanner portion
It is grouped into, shaft portion and transducer portion are Split type structure, and both are connected by nipple, first will when operation is used
Both get up in succession, and in order to protect nonexpondable transducer and ultrasonic knife bar, shaft portion and transducer portion are by having
Limiter amount is threadedly coupled, and this connection strength is completed by adnexa torque spanner.Doctor is before surgery, it is necessary to first connect ultrasonic knife bar
And transducer, torque spanner pass through knife bar, insert rotary handle endoporus in, transducer is held on the other hand, torsion is held on the other hand and is pulled
Handss, the strength of knife bar and transducer threaded connection is controlled by torque spanner.Operate and its 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, impact ultrasound knife performance, or connection strength is too quickly, twists into two parts ultrasonic knife bar or transducer.Every time
Operation consent will repeat the assembling again between apparatus, delay operating time.And torque spanner is easy to lose de-, makes
Into pollution, it is impossible to use, ultrasound knife knife bar and transducer is caused to connect, ultrasound knife cannot work.
Utility model content
The deficiencies in the prior art in view of the above, this utility model provides a kind of ultrasound knife torsion integration knob and sets
There is the ultrasound knife of the knob, when performing the operation using ultrasound knife, be easy to the connection of tool bit part and transducer portion.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of ultrasound knife torsion integration knob, it includes ratchet-gear wheel adapter sleeve (1), torsion knob (2) and encapsulated layer
(3), there are the flexure strip (5) of two or three or more, the outer surface of ratchet-gear wheel adapter sleeve (1) in the endoporus of torsion knob (2)
Multiple ratchets (4) are distributed with, into being forward distributed, into engagement shape, torsion knob (2) exists ratchet (4) for flexure strip (5) and ratchet (4)
Under certain steering external force clockwise effect, flexure strip (5) can take cunning along ratchet (4), and hear clear and melodious sliding sound of taking, otherwise
Torsion knob (2) certain counterclockwise rotation to external force effect under, flexure strip (5) then it is ratcheting live ratchet (4).
Step (7) is by back-off in elastic back-off (6) and torsion knob (2) endoporus on the ratchet-gear wheel adapter sleeve (1)
Connection.
Encapsulated layer (3) injection is encapsulated on torsion knob outer surface.
This utility model also provides a kind of ultrasound knife for being provided with ultrasound knife torsion integration knob, and it includes knife bar component
(I), Handleset (II) and transducer assemblies (III), the female thread of ultrasonic knife bar one end of knife bar component (I) central inner
(10) and the one end of transducer assemblies III external screw thread (11) by the limited strength threaded connection of ultrasound knife torsion integration knob；It is super
The ratchet-gear wheel adapter sleeve (1) of sound knife torsion integration knob is linked into an integrated entity by pin-and-hole (9) with ultrasound knife shaft portion (I)；
Ultrasound knife torsion integration knob is rotated with Handleset (II) by the stopper slot (12) arranged on ratchet-gear wheel adapter sleeve (1) and connected
Connect.
The beneficial remarkable result that this utility model has is：
Constant torque structure is integrated on rotary knob, has both ensured the constant screw thread of shaft portion and transducer portion
Connection strength, and without any part, do not change original mode of operation and volume yet, performing the operation, it is very convenient to use, while
The drawbacks of preventing single stubborn torque wrench adnexa from losing de- and polluting again, or can not find, and apparatus can not be used.
This utility model uses particularly convenient, it is to avoid again assembly manipulation is difficult for apparatus, reduces operating time, avoids in addition
Lose de- and pollute, it is impossible to use.
