Summary of the invention

In order to overcome the deficiency that the microtrauma puncture angle can't accurately be controlled in the prior art, the purpose of this utility model is to provide a kind of B ultrasonic guided puncture positioner, and this device is not only simple in structure, easy to use, and puncture angle is easy to adjust, accurate positioning.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of B ultrasonic guided puncture positioner, it is characterized in that: but it comprises that a suit is fixed on the link on the Ultrasonic-B probe, be provided with locking member in this link one side, opposite side is fixed with pedestal, the first angular adjustment bar is locked in described pedestal through first locking piece, the second angular adjustment bar is locked in the fork-join portion of the first angular adjustment bar through second locking piece, the bulb of one positioning head body is matched with in the ball cup of the second angular adjustment bar other end, on this ball cup, be provided with the 3rd locking piece, the 3rd locking piece can be locked in the bulb of positioning head body in the ball cup of the second angular adjustment bar, offers the puncture pilot hole of several different-diameters on described positioning head body.

The described puncture pilot hole that is opened in the different-diameter on the positioning head body is 4.

This utility model has comprised that a suit is fixed on the link of Ultrasonic-B probe, the first angular adjustment bar, the second angular adjustment bar, a positioning head body and first locking piece, second locking piece, the 3rd locking piece, this utility model is by rotational angle adjusting rod and positioning head body, carry out the puncture angle adjustment, by locking piece is corresponding respectively each parts is carried out the position adjustments locking then.The puncture pilot hole of the different-diameter that is provided with on the positioning head body can satisfy the coupling of different model puncture needle.This utility model is simple in structure, easy and simple to handle, puncture angle is easy to adjust, accurate positioning.

Description of drawings

Below in conjunction with drawings and Examples this utility model is described further.

Accompanying drawing is a kind of structural front view of the present utility model.

The specific embodiment

In the accompanying drawings, a kind of B ultrasonic guided puncture positioner, it comprises that but a suit is fixed on the link 1 on the Ultrasonic-B probe, is provided with the locking member of being made up ofbolt 201 and anut 202couplings 2 in these link 1 one sides, link 1 and Ultrasonic-B probe can be carried out fixed-site bylocking member 2.

In the accompanying drawings, the opposite side at link 1 is fixedly welded withpedestal 3.

The firstangular adjustment bar 4 is assemblied in thepedestal 3, and first locking piece of being made up ofbolt 501 and anut 502couplings 5 is locked inpedestal 3.

As shown in drawings, the other end of the firstangular adjustment bar 4 is a fork-join portion.One end of the secondangular adjustment bar 6 is assemblied in the fork-join portion of the first angular adjustment bar 4.As shown in drawings, 7 pairs firstangular adjustment bars 4 of second locking piece of being made up of abolt 701 and anut 702 couplings are connected with the secondangular adjustment bar 6, and the secondangular adjustment bar 6 can be locked in the fork-join portion of the firstangular adjustment bar 4.

In the accompanying drawings, the other end of the secondangular adjustment bar 6 is aball cup 601, thebulb 801 of onepositioning head body 8 is matched with in thisball cup 601, thebulb 801 ofpositioning head body 8 can be locked in theball cup 601 of the secondangular adjustment bar 6 being provided with the3rd locking piece 9, the three locking pieces of forming by abolt 901 and anut 902coupling 9 on thisball cup 601.

As shown in drawings, on positioninghead body 8, offer thepuncture pilot hole 10 of four different-diameters, with the puncture needle of coupling different model.

When this utility model uses clinically, suit link 1 on Ultrasonic-B probe at first, and be fixed on Ultrasonic-B probe withlocking member 2, after determining the puncture target,, rotate the firstangular adjustment bar 4, the secondangular adjustment bar 6 and positioninghead body 8 at different parts, carry out the puncture angle adjustment, throughfirst locking piece 5,second locking piece 7, the3rd locking piece 9 its position is locked then, puncture needle passes thepuncture pilot hole 10 of corresponding diameter then, implements puncture.

Parts of the present utility model all repeatedly repeated disinfection use, have simple in structure, easy and simple to handle, puncture angle is easy to adjust, the advantage of accurate positioning.
