Abstract

The utility model provides a medical auxiliary devices, slidingtype puncture locator is including mounting and slider. The mounting comprises parts such as anti -skid rubber pad, base, universal joint, slide bar, scales, there are parts such as cylinder groove, cylinder ears groove, hasp on the slider. The syringe cylinder that has the pjncture needle can be fixed on the slider, along slide bar arbitrary slip from top to bottom to the accurate reading of slider position of reading out on the scale. The device can go into the accurate positioning of pin mark, needle angle, the inserting needle degree of depth when the puncture operation.

Description

Sliding type puncture localizer

Technical field

This utility model relates to a kind of medical auxiliary apparatus, specifically a kind of sliding type puncture localizer.

Background technology

Puncture puncture needle is thrust body cavity to extract secretions and chemically examine, and does contrast examination to body cavity injecting gas or contrast agent, or to a kind of Clinics of injection of medicine in body cavity.The difficult point of puncture procedure is that body surface enters pin mark location, needle angle location, depth of needle location, wherein depth of needle location particularly difficulty.Whether accurate Needle localization is, will be directly connected to the success or failure of operation.

The technology of current solution Needle localization problem has two classes: one is the graduated puncture needle of a kind of band of design, judges depth of needle after entering pin by the puncture needle scale stayed outside body surface; Two is the graduated puncture positioning devices of a kind of band of design, is fixed on by syringe on puncture locator, is determined into the pin degree of depth by scale.The former due to needle tubing too thin, scale can only be accurate to Centimeter Level, and millimetre-sized location still needs artificial judgement.The latter can read millimetre-sized scale on puncture locator, has better application prospect.But existing puncture locator or structure are too complicated, volume is too huge, or structure is too simple, location is accurate not.In addition, this fixation problem in body surface of puncture locator does not have a kind of easy way to solve yet.Still suitable puncture locator is not had at present in clinical practice application.

Summary of the invention

The purpose of this utility model be to provide a kind of structure simple, be of moderate size, the puncture locator of easy to operate, accurate positioning, to solve the problem.

The sliding type puncture localizer that this utility model provides, is made up of fixture and sliding part two parts.Fixture is connected and composed by antiskid glue cushion, base, Hooks coupling universal coupling, slide bar; Sliding part is made up of syringe groove, syringe ears groove, snap close three part.The circular arc corner that fixture base has pair of openings outside, the region during corner surrounds is formed into pin region.The protractor graduated disc that fixture base is formed by the graduation mark of divergent shape in addition.Antiskid glue cushion is bonded in below base, directly can contact with skin surface, prevents sliding type puncture localizer from moving on skin and causes displacement.Slide bar is connected with base by Hooks coupling universal coupling, and can relative to base to all directions skewed at any angle.Slide bar there is scale, sliding part reading at an arbitrary position can be read on scale.Utilize syringe groove, injector syringe and sliding part can combine by syringe ears groove securely, jointly slide up and down along slide bar.

The utility model has the advantages that: body surface can be carried out accurately and easily and enter pin mark location, needle angle location and the location of depth of needle.

Accompanying drawing explanation

Accompanying drawing 1 is schematic diagram of the present utility model, and in fig. 1,1 is base, and 2 is antiskid glue cushions, and 3 is Hooks coupling universal couplings, and 4 is protractor graduated discs, and 5 is slide bars, and 6 is scales, and 7 is sliding parts, and 8 is snap closes, and 9 is syringe grooves, and 10 is syringe ears grooves.Base (1), antiskid glue cushion (2), Hooks coupling universal coupling (3), protractor graduated disc (4), slide bar (5) form fixture jointly.Slide bar (5) there is scale (6).Sliding part (7) comprises snap close (8), syringe groove (9), syringe ears groove (10) three part.The injector syringe being connected with puncture needle can be fixed on sliding part (7) by syringe groove and syringe ears groove.Sliding part (7) can slide up and down along slide bar (5), accurately can be read the optional position at sliding part (7) place by scale (6).

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in detail as follows.

Determine at body surface and after labelling enters pin mark, sliding type puncture localizer base be placed in body surface appropriate location, make pin mark be positioned at base circular arc corner surround formed enter pin region, antiskid glue cushion and skin surface are fitted.One holds sliding type puncture localizer and prevents relative movement, to locate into pin mark.The injector syringe of connecting puncture needle is snapped in syringe groove, syringe ears groove, syringe is fastened on sliding part.Pull slide bar, by the rotation adjustment needle angle of Hooks coupling universal coupling.A hand-held sliding part, along sliding bar, makes puncture needle head contact body surface and enters pin mark position, scale reads and scale value before recording inserting needle.According to the puncture depth of needle of actual set, scale value when calculating inserting needle terminal on scale.Advance sliding part inserting needle, through inserting needle terminal scale value.The tight sliding part of trip lock buckle, carries out the operation of extracting bodily fluid or liquid medicine injection.After puncture procedure, open snap close, extract puncture needle, remove sliding type puncture localizer.Terminate puncturing operation.
