Abstract

The utility model provides a kind of thin spinal needle of cutting type needle point, including needle tubing, needle stand and connecting column, and needle tubing is equipped with graduation mark, and the needle point of needle tubing is cutting type, and needle stand is equipped with indicator hole corresponding with needle point cutting diagonal cut joint；Needle stand is equipped with anti-skidding grip part, and extends outward two groups of force wing plates close to needle stand and needle tubing junction, makes power for finger, in puncture process, in 3 hands of needle tubing, increases the stability of spinal needle；Importantly, 1 internal diameter of needle tubing is 0.5mm, long 9cm, through many years clinical verification, the probability having a headache after the lumbar anesthesia that the spinal needle of this bore causes is lower.The graduation mark of the utility model needle tubing judges depth of needle convenient for anesthetist, to increase the accuracy of anesthesia work.

Description

A kind of thin spinal needle of cutting type needle point

Technical field

The utility model belongs to medical anaesthetic apparatus field, and in particular to a kind of thin spinal needle of cutting type needle point.

Background technique

The medical instrument of subarachnoid anesthesia is mainly spinal needle, in existing spinal needle mainly with No. 22 spinal needles and No. 25 guiding spinal needles.No. 22 spinal needle internal diameters are thick, and wearing out arachnoid keeps cerebrospinal fluid leakage more, cause Headache, backache Incidence is big, and local damage is big；When No. 25 guiding spinal needles are punctured using nib type needle point, the power that is such as hampered needle tubing fractures risk Greatly, it is unobvious that sense is broken through when puncture, when with guidance needle, needle internal diameter is slightly big to tissue and ligament injury, as the certain partially thin patients of chance It is big directly to wear out arachnoid incidence.Clinically it is badly in need of wanting a kind of tissue damage small and the spinal needle of low complication at present.

Summary of the invention

Aiming at the deficiencies in the prior art, the utility model provides a kind of thin spinal needle of cutting type.

For above-mentioned purpose, technical solutions of the utility model are as follows:

A kind of thin spinal needle of cutting type needle point, including needle tubing, needle stand and connecting column, needle tubing internal diameter are 0.5mm, long 9cm, needle Pipe is equipped with graduation mark, and the needle point of needle tubing is cutting type, and needle stand is equipped with indicator hole corresponding with needle point cutting diagonal cut joint.

Above-mentioned needle stand is equipped with anti-skidding grip part, and extends outward two groups of force wing plates close to needle stand and needle tubing junction, Make power for finger, in puncture process, in 3 hands of needle tubing, increases the stability of spinal needle.

The utility model has the advantages that the utility model internal diameter is small, Headache, pain in the loins probability are substantially reduced；Using cutting type needle point, needle Length of tube is suitable for reducing anestetic needle to fracture risk, and it is obvious that when puncture breaks through sense, is not necessarily to local anaesthesia, prevents local anaesthetics from causing office Portion's swelling causes puncture needle merging epidural space just neural blood vessel not being caused to damage, and force wing plate increases inserting needle stability.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the enlarged drawing of part A in Fig. 1.

Fig. 3 is the enlarged drawing of part B in Fig. 1.

Fig. 4 is the sectional view of Fig. 2.

In figure, 1- needle tubing, 2- needle stand, 3- connecting column；11- graduation mark, 12- needle point, 21- indicator hole, the anti-skidding gripping of 22- Portion, 23- force wing plate, 31- connection cavity.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and examples.

As shown in Figures 1 to 4, a kind of thin spinal needle of cutting type needle point, including needle tubing 1, needle stand 2 and connecting column 3, on needle tubing Equipped with graduation mark 11, the needle point 12 of needle tubing 2 is cutting type, and needle stand 2 is equipped with indicator hole corresponding with the cutting diagonal cut joint of needle point 12 21；Needle stand 2 is equipped with anti-skidding grip part 22, and extends outward two groups of force wing plates 23 with 2 junction of needle tubing close to needle stand 2, can Make power for finger, in puncture process, in 3 hands of needle tubing, increases the stability of spinal needle；31 side of connection cavity of connecting column 3 Just other medical devices are connected.

Importantly, 1 internal diameter of needle tubing is 0.5mm, long 9cm, through many years clinical verification, what the spinal needle of this bore caused The probability having a headache after lumbar anesthesia is lower.

The graduation mark of needle tubing is equipped with mark every 1cm, depth of needle is judged convenient for anesthetist, to increase anesthesia work The accuracy of work.

There is an inclined edge in the front end of the needle tubing of the utility model, and anesthetist chooses vertebra gap, and anesthetist can use Directly enter puncture method or side enters puncture method and punctures into cavum subarachnoidale, then pulls out flexible conduit indwelling after cavum subarachnoidale Needle tubing is injected anaesthetic by flexible conduit.

The above content is the detailed descriptions for combining optimal technical scheme to do the utility model, and it cannot be said that utility model Specific implementation be only limitted to these, for made under the premise of not departing from the utility model thought it is simple deduction and replacement, all It should be considered as the protection scope of the utility model.

Claims

1. a kind of thin spinal needle of cutting type needle point, including needle tubing, needle stand and connecting column, it is characterised in that: needle tubing internal diameter is 0.5mm, long 9cm, needle tubing are equipped with graduation mark, and the needle point of needle tubing is cutting type, and needle stand, which is equipped with, cuts diagonal cut joint pair with needle point The indicator hole answered.

2. the thin spinal needle of cutting type needle point as described in claim 1, it is characterised in that: the needle stand of stating is equipped with anti-skidding gripping Portion, and two groups of force wing plates are extended outward close to needle stand and needle tubing junction, make power for finger.
