Problems solved by technology

[0002] At present, minimally invasive puncture positioning under the guidance of B-ultrasound has been widely used in clinical practice. However, due to the unclear imaging of the relatively small puncture needle / rod used by B-ultrasound for minimally invasive techniques, it often leads to inaccurate puncture positioning. Accurate circumstances that left permanent scars on eloquence
With the development of medical technology, researchers have considered improving the B-ultrasound-guided puncture positioning device, such as: Chinese utility model patent, the patent application number is: 200520099123.1 The invention name is: "Navigation Needle", compared with it, The present invention achieves the same function by another method. The strong reflectivity of the beacon needle under ultrasound is poor, the clarity is not enough, and it is difficult to observe.

Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0010] According to Fig. 1, Fig. 2 can know, cutter head 5 and cutter bar 3 of the present invention are on the same horizontal line, cutter head 5 is connected with handle of a knife 6 by cutter bar 3, and balloon 1 is fixed on cutter bar 3, and balloon 1 It can be made of medical silica gel and rubber, and the distance between its edge and the cutter head 5 is fixed. The cutter bar 3 is connected with the handle 6, which is beneficial for externally connecting the treatment source. The distance between the two rear ends of the balloon 1 and the cutter head 5 is Fixed, the shape of the balloon 1 is circular, oval or irregular. The liquid injection tube 2 is attached on the cutter bar 3, and one end of the liquid injection tube 2 is inserted in the balloon 1, and the liquid injection tube 2 is sealed with the balloon 1.

Abstract

The invention discloses a saccule delomorphic puncture localizer, including cutter head, knife bar, water-filling saccule and water injection pipe. The saccule is mounted on the knife bar, and the distance between two sides of the saccule and the cutter head is changeless, the water injection pipe is attached to the knife bar, and inserted into saccule from the back of water-filling saccule to inject water to the saccule when needed. The invention is simple in structure and convenient to operate, it is effective to prevent penetration of partial histiocyte by mistake, decrease the difficulty and risk of the operation. The invention is suit for puncture positioning when doing intervened treating.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically relates to a balloon imaging puncture positioner, which is suitable for puncture positioning in minimally invasive surgical treatment under the guidance of gynecological ultrasound. Background technique [0002] At present, minimally invasive puncture positioning under the guidance of B-ultrasound has been widely used in clinical practice. However, due to the unclear imaging of the relatively small puncture needle / rod used by B-ultrasound for minimally invasive techniques, it often leads to inaccurate puncture positioning. The exact circumstances left permanent scars on eloquence. With the development of medical technology, researchers have considered improving the B-ultrasound-guided puncture positioning device, such as: Chinese utility model patent, the patent application number is: 200520099123.1 The invention name is: "Navigation Needle"...
