Abstract
The invention discloses a marrow puncture needle which is structurally characterized in that a puncture needle sheath is fixedly connected with a grain-shaped rotating body, a needle core, a limiting stopper, a needle rod and an arc needle seat are fixedly connected, and a clamping opening of the limiting stopper of the center of the grain-shaped rotating body is connected with the limiting stopper in a non-fixed and embedded mode. A telescopic positioner is connected with the grain-shaped rotating body by an inner spiral and an outer spiral, and the telescopic positioner is formed by connection of multiple sleeves through a spiral structure. Protruded grain-shaped lines on the surface of the grain-shaped rotating body increase friction force between a finger pulp and the rotating body. The needle rod between the limiting stopper and the arc needle seat extends whole length of the puncture needle, compared with a common puncture needle, contact area of the arc needle seat and a palm is increased, and the length of the puncture needle sheath is obviously shortened. When puncture is conducted, an operator rotates the telescopic positioner, the length of the puncture needle sheath is adjusted by spiral stretching of the sleeves, the palm of the operator ejects the arc needle seat, a thumb and an index finger tightly hold the grain-shaped rotating body to rotate needle entering, and the puncture needle sheath is completely exposed out of vision of the operator, so that stability and comfort of puncture are improved, and marrow dilution rate is reduced.
Description
Affiliated technical field
The present invention discloses a kind of marrow puncture needle, belongs to technical field of medical instruments.
Background technology
Marrow puncture needle commonly used mainly is made of stylophore, nook closing member, needle stand and localizer clinically at present, is connected by helical structure between localizer and stylophore.After regulating needle length by rotational positioner during puncture, palm withstands needle stand, and thumb and forefinger are held localizer vertical facial inserting needle.Nearer apart from piercing needle because of the palm finger on the one hand, the site of puncture fully can not be exposed to the operator visual field, the long probability that increases the bone marrow dilution of while stylophore, on the other hand because firmly the rotating screw structure is often loosening, after loosening, marrow puncture needle easily rocks, the smooth easy slippage of needle stand, little the making of needle stand and centre of the palm contact area lacks comfort when puncturing simultaneously, increases the probability of bone marrow aspiration failure.
Summary of the invention
To commonly use marrow puncture needle stability deficiency, comfort shortage, the little shortcoming in the operation visual field in order overcoming, to the invention provides a kind of marrow puncture needle, it is simple in structure, and is simple for production, the flow process that simplifies the operation, stability and the comfort of raising bone marrow aspiration.
The technical solution adopted for the present invention to solve the technical problems is: 1. this puncture needle is comprised of puncture stylophore, flexible localizer, stricture of vagina shape rotary body, nook closing member, stop, shank, arc needle stand, be fixedly connected with between puncture stylophore and stricture of vagina shape rotary body, be fixedly connected with between nook closing member, stop, shank and arc needle stand, stricture of vagina shape rotary body center stop bayonet socket is connected connection with the stop on-fixed.2. flexible localizer connects by internal and external screw with stricture of vagina shape rotary body, and flexible localizer is connected to form by helical structure by several sleeves, has the rotary extension function.3. the stricture of vagina shape line increase of stricture of vagina shape rotary body protrusion of surface refers to the frictional force between abdomen and stricture of vagina shape rotary body.4. the entire length that between stop and arc needle stand, shank extends puncture needle, with relatively arc needle stand and the increase of palm contact area of conventional puncture needle, the puncture stylophore obviously shortens.
The invention has the beneficial effects as follows: operator's rotary extension localizer during bone marrow aspiration, regulate puncture stylophore length by spiral expanding between sleeve, the arc needle stand is withstood in the centre of the palm, thumb and forefinger are held stricture of vagina shape rotary body rotation inserting needle, the puncture stylophore is exposed to the operator visual field fully and is difficult for rocking and slippage, improve comfort and the stability of puncture, reduce bone marrow dilution probability.

The specific embodiment
In embodiment as shown in the figure, be fixedly connected with between the puncture stylophore (1) of this marrow puncture needle and stricture of vagina shape rotary body (3), be fixedly connected with between nook closing member (8), stop (9), shank (10) and arc needle stand (11), stop (9) is connected 12 with the stop bayonet socket) between the chimeric connection of on-fixed, connect by the helical structure on-fixed between flexible localizer (4) sleeve (12).during bone marrow aspiration, at first the operator is placed in stop (6) in stricture of vagina shape rotary body (3) center stop bayonet socket (9), make nook closing member (8), stop (9), shank (10), arc needle stand (11) and puncture stylophore (1), stricture of vagina shape rotary body (3) on-fixed is integrally connected, and by the internal coiling (7) of flexible localizer (4) and the external spiral (2) of stricture of vagina shape rotary body (3), flexible localizer (4) is connected on stricture of vagina shape rotary body (3), operator's rotary extension localizer (4), regulate the suitable length of puncture stylophore (1) by the stretching motion of helical structure (5) between sleeve (6), arc needle stand (11) is withstood in the centre of the palm, thumb is held the vertical patient's surface of bone rotation of stricture of vagina shape rotary body (3) inserting needle with forefinger, flexible localizer (4) is hampered by the site of puncture soft tissue and prevents that inserting needle is excessively dark, extract nook closing member (8), locate to connect syringe bone marrow extraction liquid smear at the syringe interface (13) of stricture of vagina shape rotary body (3), need take off flexible positioning body (4) when running into the obese patient.
Claims (5)
1. a marrow puncture needle, is characterized in that being made of puncture stylophore, flexible localizer, stricture of vagina shape rotary body, nook closing member, stop, shank, arc needle stand.
2. be fixedly connected with between marrow puncture needle according to claim 1, puncture stylophore and stricture of vagina shape rotary body, be fixedly connected with between nook closing member, stop, shank and arc needle stand.
