Medical personal can accurately puncture the focus by using the utility model so that the treatment time is shortened, and the pain of patients is lightened.

Description

Ultrasonic guide puncture apparatus

This utility model belongs to medical apparatus and instruments, particularly with the supporting guiding piercing device of Ultrasound Instrument.

Along with the development of China's medical industry, utilize the pathological changes of ultrasonic guidance puncture diagnosis and treatment human internal organ and tissue, more and more be subjected to the attention of medical institutions.At present, domestic hospital adopts will make the puncture supporter bonding and be fixed in method on the ultrasonic probe, both influence the probe outward appearance, use inconvenience again, and can not adapt to the requirement of selecting the operation of different size puncture needle for use, bring inconvenience and will bother to the medical worker.

The purpose of this utility model is to provide a kind of being sandwiched in outside the probe, and can adjust the ultrasonic guidance piercing device of puncture needle needle angle.

This utility model comprises clamping, angular adjustment and inserting needle three parts that lead.This device adopts U type support to be clamped on the Ultrasonic-B probe outside, and the inserting needle guiding mechanism is loaded on the graduated tile, by the adjusting to the graduated tile corner, can adjust the needle angle and the degree of depth of puncture needle neatly, makes puncture needle accurately hit lesions position.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is that the A of Fig. 2 is to revolved view.

Fig. 4 is Fig. 3 " B-B " cutaway view.

Describe concrete solution of the present utility model in detail below in conjunction with accompanying drawing.

As shown in drawings, this device is clamped on the support 4 in the Ultrasound Instrument probe outside for U-shaped, and support 4 one side guides are surrounded by pressing plate cover 1 outward, and pressing plate cover 1 selects soft material to make; Be shaped with a screw at support 4 opposite side pressing plates middle part, be rotary with bridge screw 7 in the screw, be fixed with round clamp 6 in the end of bridge screw 7, the round clamp 6 outer round clamp covers 5 that are surrounded by, round clamp cover 5 selects soft material to make. Be fixed with support plate 9 at support 4, scale plate 8 is actively coupled by screw 2 with support plate 9, sector at support plate 9 has arc groove, be shaped with the readable graduation mark that goes out angle on the scale plate 8, the arc groove that lock-screw 3 passes on the support plate 9 is connected with scale plate 8, unclamp lock-screw 3 and can regulate rotational angle, screw then and can be fixed in required angle position.

Small end at graduated tile 8 is shaped on perpendicular support plate 13, has the axial needle tray that some degree of depth do not wait on the periphery of needle stand 10, and the degree of depth of needle tray and width just are the diameter of each puncture needle; The central authorities of needle stand 10 have shoulder hole, and spring 11 is housed in the hole, and needle ingot shaft 15 passes spring 11, screw in the screw on the support plate 13, and the needle stand 10 outer needle stand covers 12 that are with are opened an axial groove on the tube wall of needle stand cover 12; Groove width is bigger slightly than maximum specification puncture needle diameter.Have two mutually perpendicular straight troughs on needle stand 10 and end face that support plate 13 engages, riveting has two alignment pins 12 on support plate 13, terminates in respectively in the straight trough of needle stand 10 ends, plays the role of positioning.

This utility model is simple in structure, and is easy to operate, and can select the puncture needle specification flexibly for use according to the diagnosis and treatment needs, makes the puncture needle inserting needle accurate, made things convenient for the medical worker, also alleviated patient's misery.

Embodiment: metalworks such as the support of this device, graduated tile, needle stand, needle stand cover, needle ingot shaft all adopt rustless steel (as: 2Cr13), and pressing plate cover and round clamp cover adopt rubber or plastics; 10 °-50 ° of graduated tile adjustable-angle scopes, the outer needle tray number of needle stand is 4, it is orthogonal that the end face that needle stand engages with support plate is opened two grooves, and at 45 with these face two relative needle tray centrages.According to diagnosing and treating the puncture needle that needs are selected different size for use, specification has 0.7mm, 0.8mm, 0.9mm, 1.4mm, 2.0mm etc., and the needle tray size on the needle stand is corresponding with it.
