Description

A kind of medical puncture needle

Technical field

This utility model belongs to technical field of medical instruments, relates to a kind of Novel puncture needle particularly.

Background technology

The Diagnosis and Treat of a lot of disease needs to puncture to patient, and common puncture needle needle body does not have scale, because the experience of operator often can not hold the degree of depth of puncture during puncture, brings injury to patient; Sometimes also because of the reason of operator or the reason syringe needle meeting curving of material, make puncture unsuccessful, also can bring injury to patient, and add work difficulty to operator.

Summary of the invention

The purpose of this utility model is to provide a kind of medical puncture needle, and this puncture needle precisely effectively can control the weight that punctures, and avoids syringe needle curving, can also change puncture direction and angle freely.

The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: a kind of medical puncture needle, comprises inner core and overcoat, and overcoat has different size locating slot; Inner core comprises syringe needle and needle body, syringe needle is tapered, seamlessly transit with needle body, needle body has the latch corresponding with locating slot, latch and locating slot coordinate, and described needle body end has been threaded connection handle, handle has screw thread platform, overcoat has handle A, and handle A has tapped through hole, and handle and handle A pass through threaded engagement; It is characterized in that: described inner core is hollow; Syringe needle and the needle body of described inner core are that moveable hinge is connected, and syringe needle inserts needle body by seal wire and controls guiding by handle.

Described a kind of medical puncture needle, is characterized in that: described put scale outward.

During use, with inner core through overcoat, reserve puncture weight by latch and locating slot, or directly with the scale location put outward; Change puncture direction and angle can also be connected by syringe needle with the moveable hinge of needle body, arrive object accurately.

This utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, this utility model solves the deficiencies in the prior art, effectively can control the weight that punctures, avoid syringe needle curving, puncture direction and angle can also be changed freely, structure is simple, easy to use, reduce the generation of malpraxis, save time, alleviate the work difficulty of medical worker, increase work efficiency.

Fig. 1 is structural representation of the present utility model;

Labelling in figure: 1, inner core, 2, overcoat, 3, locating slot, 4, syringe needle, 5, needle body, 6, latch, 7, handle, 8, handle A.

Detailed description of the invention

Below in conjunction with accompanying drawing and preferred embodiment, to according to a kind of medical puncture needle detailed description of the invention, feature and the effect thereof that the utility model proposes, be described in detail as follows.

See Fig. 1, a kind of medical puncture needle, comprise inner core 1 and overcoat 2, overcoat 2 has different size locating slot 3; Inner core 1 comprises syringe needle 4 and needle body 5, syringe needle 4 is tapered, seamlessly transit with needle body 5, needle body 5 has the latch 6 corresponding with locating slot 3, latch 6 and locating slot 3 coordinate, and described needle body 5 end has been threaded connection handle 7, handle 7 has screw thread platform, overcoat 2 has handle A8, and handle A8 has tapped through hole, and handle 7 and handle A8 pass through threaded engagement; It is characterized in that: described inner core 1 is for hollow; The syringe needle 4 of described inner core 1 is with needle body 5 for moveable hinge is connected, and syringe needle 4 inserts needle body 5 by seal wire and controls guiding by handle 7.

Described a kind of medical puncture needle, is characterized in that: described overcoat 2 has scale.

During use, with inner core 1 through overcoat 2, reserve puncture weight by latch 6 and locating slot 3, or directly with the scale location on overcoat 2; Can also be connected with the moveable hinge of needle body 5 by syringe needle 4 and change puncture direction and angle, arrive object accurately.

This utility model solves the deficiencies in the prior art, effectively can control the weight that punctures, avoid syringe needle curving, can also change puncture direction and angle freely, structure is simple, easy to use, reduces the generation of malpraxis, save time, alleviate the work difficulty of medical worker, increase work efficiency.

The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to this utility model, anyly do not depart from technical solutions of the utility model content, the any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
