Specific embodiment

Below with reference to attached drawing, the utility model will be further described, it should be noted that following embodiment is with this Premised on technical solution, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is simultaneously It is not limited to the present embodiment.

As shown in figs 1-9, a kind of ultrasonic interventional therapy system, including puncture needle 1, puncture supporter 3 and location transmitters 2, institute Location transmitters 2 are stated for emitting the puncture needle 1, and are connected to the puncture supporter 3；The location transmitters 2 include outer tube 21, inner tube 22 and propulsion elastic component 23, said inner tube 22 is movably sheathed in the outer tube 21, and passes through the propulsion bullet Property part 23 connect；The rear portion of the outer tube 21 is equipped with card hole 211, and (in the present embodiment, the two sides at 21 rear portion of outer tube are equipped with card Hole), the outer surface of said inner tube 22 is equipped with bayonet lock 221 (bayonet lock 221 there are two accordingly, setting in the present embodiment), when the card When pin 221 is with inner tube activity to the position of card hole 211, the bayonet lock 221 can be caught in card hole 211, and work as the bayonet lock 221 It is stuck in the propulsion elastic component 23 in the card hole 211 and is in compressive state.

The working principle of above-mentioned ultrasonic interventional therapy system is: pulling inner tube in outer in-pipe, and bayonet lock is moved When moving the position of card hole, bayonet lock is because the elasticity of itself flicks and is stuck in card hole, to complete the locking to inner tube.Work as needs When being punctured, the bayonet lock is pushed to leave card hole, in the case where promoting the elastic force effect of elastic component, said inner tube drives the puncture Needle projects, and realizes and punctures.

Further, the inner wall of said inner tube 22 is equipped with internal screw thread 222, the outer wall of the puncture needle 1 be equipped with it is described interior The external screw thread 11 that screw thread 222 matches.The external screw thread of puncture needle and the internal screw thread of inner tube match, can be with by rotation puncture needle Position of the puncture needle in inner tube is controlled, realizes the accurate control and positioning for puncturing distance.

Further, the outside of the outer tube 21 is equipped with elastic trigger member 212 corresponding with 211 position of card hole.Pass through bullet Property trigger member press elastic trigger member when needing to puncture, can by bayonet lock from card hole to the direction of internal tube promote, Elastic trigger member automatically replies original position after the completion.

Further, cushion 213 is equipped between the outer wall front end of said inner tube 22 and the inner wall front end of the outer tube 21. The cushion can buffer the dump energy of inner tube when puncturing, and prevent inner tube from rebounding.

Further, the front end of the outer tube 21 be equipped with puncture supporter linkage section 214, the puncture supporter linkage section 214 it is interior Wall is equipped with groove 215；The rear end of the puncture supporter 3 is equipped with the puncture Holder joint 31 to match with the puncture supporter linkage section 214, The outer wall for puncturing Holder joint 31 is equipped with the protrusion 32 to match with the groove 215.In the present embodiment, the groove tool There are two, the protrusion is matched.When location transmitters are connected to puncture supporter, the puncture Holder joint of puncture supporter is inserted into The puncture supporter linkage section of the location transmitters, then rotational positioning transmitter is until the protrusion is caught in the groove and is Only, to realize screwing for location transmitters and puncture supporter.

Further, the cross section of the outer tube 21 is in regular hexagon, and inner tube 22 is located at the transversal of the part in outer tube 21 Face is in regular hexagon, is matched with the outer tube 21.The design can prevent inner tube from rotating in outer tube.
