Detailed description of the invention
The embodiment of utility model is described by particular specific embodiment below, and person skilled in the art scholar the content disclosed by this description can understand other advantages and effect of utility model easily.It should be noted that the forward mentioned by this utility model, oppositely, is when knife bar assembly 1 is connected with transducer, to screw as forward, pulls down as oppositely.
Embodiment
As shown in Figures 1 to 4, this utility model provide a kind of for ultrasound knife connect twist structure, comprise knife bar assembly 1 and be set in the knob body 2 outside knife bar assembly 1, in this example, knife bar assembly 1 comprises inner sleeve 12 and is connected to the union joint 14 at inner sleeve 12 rear portion, inner sleeve 12 is enclosed within outside ul-trasonic irradiation bar 11, inner sleeve 12 overcoat has trocar sheath 13, inner sleeve 12 and ul-trasonic irradiation bar 11 are connected to haircut, and same bearing pin 17 passes perpendicularly through trocar sheath 13, inner sleeve 12 and ul-trasonic irradiation bar 11; Union joint 14 overcoat limited location sleeve pipe 15, is threaded limit casing 15 with union joint 14.Elastic supporting mechanism 16 kink is outside limit casing 15, and two ends are against on limit casing 15 and union joint 14 respectively.
Trocar sheath 13 outer wall is circumferentially provided with at least two stop parts, is 4 projections 18 in this example, and is uniformly distributed along trocar sheath 13 circumference, protruding 18 with trocar sheath 13 integrated injection molding, and with trocar sheath 13 outer wall rounding off.2-8 etc. can be set in other embodiments, knob body 2 is provided with and corresponding with stop part twists part, twist in part and stop part two kinds of parts, at least one parts have elasticity, as long as namely when two kinds of parts compress mutually, having a kind of parts elastic deformation can occur, can certainly be all that elastic material is made; When rotating forward knob body 2, twisting part and being pressed on stop part, when torsion is greater than preset value, twists part and cross stop part and depart from stop part; When rotating backward knob body 2, stop part blocks twists part, limits it and rotates.
The direction that the height of protruding 18 rotates forward along knob body 2 is increased gradually, is formed and twists the arcwall face or inclined plane that part compresses.Stop part cross section is triangle or wedge shape, twists part and knob body 2 is one-body molded, and one-body molded convenient for production, stabilized structure not easily drops.
Knob body 2 offers and protruding 18 corresponding windows 21, window 21 is provided with 4 cantilevers 22 along knob body 2 circumference, and this cantilever 22 is twists part, and the free end of this cantilever 22 inwardly stretches into the inner chamber of knob body 2, and near or be pressed on knife bar assembly 1 outer wall.The free end of cantilever 22 corresponds to the low one end of projection 18, and the other end corresponds to the high one end of projection 18, and when rotating backward knob body 2, one end that stop part is high is blocked and twisted part.
In other embodiments, twisting part can for being arranged on the block on knob body 2 inwall, trocar sheath 13 outer wall arranges outstanding parts or recess coordinates with block, or twist part to be formed by knob body 2 inwall is outwards recessed, stop part is be arranged on the projecting part on trocar sheath 13 outer wall, as long as meet its torsional requirements, when rotating forward knob body 2, this face that compresses of twisting part and stop part is inclined plane, can cross stop part when torsion is greater than certain value.
When knife bar assembly 1 is connected with transducer, to screw as forward, pull down as oppositely; As shown in Figure 5, rotate forward in knob body 2 process, cantilever 22 compresses protruding 18 and drives knife bar assemblies 1 together to rotate and realize and the spinning of transducer, when torsion is greater than preset value, there is reversible elastic deformation in projection 18 or cantilever 22, cause crossing protruding 18 and produce suddenly the release of moment, go round and begin again.So can ensureing the excessive threaded connector 14 that causes that do not screw or exert oneself will be caused to rupture because of the difference of people when connecting, damaging apparatus.As shown in Figure 6, when taking knife bar assembly 1 and transducer apart, cantilever 22 is directly against on protruding 18 can not cross protruding 18, and rotates simultaneously.This structure directly stubborn access node structure is arranged on apparatus originally with it, make it have torque spanner function and don't with taking off or extra installation, the situation that can not drop, easy to operate.
As mentioned above, the beneficial effects of the utility model are: meeting torque requiremnt, when not damaging apparatus, on structure assembly to apparatus itself will be twisted, have on the one hand torque spanner function and don't with taking off or extra installation, the situation that can not drop, ensures the normal connection of ultrasound knife.Structure is simple, and avoid being connected and stained appliances by external tool, doctor is easy to use, is not easy to make mistakes.
This utility model provides a kind of ultrasound knife simultaneously, comprise housing, be arranged on the trip gear on housing, also wrap above-mentioned for ultrasound knife connect twist structure, also comprise the mechanisms such as the transducer be threaded with ul-trasonic irradiation bar 11, these mechanisms all belong to prior art, clearly can express, therefore in this utility model, omitting accompanying drawing by describing.
Any person skilled in the art scholar all under the spirit and category of utility model, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that utility model discloses, must be contained by the claim of utility model.
