Abstract
The utility model discloses a novel myeloid biopsy needle and belongs to the technical field of medical apparatus and instruments. The novel myeloid biopsy needle consists of a needle tubing, a needle core and a handle. The needle core is fixedly connected with the handle; the needle tubing is connected with the handle in a mode that concave and convex bayonets are embedded; the tail end of the needle tubing of the biopsy needle is provided with one deep concave bayonet and one shallow concave bayonet; and the front end of the handle is provided with one convex bayonet. When the bone marrow biopsy is carried out, firstly, the convex bayonet is arranged in the deep concave bayonet, the needle core is exposed out of the biopsy needle tubing, the needle is convenient to enter, the convex bayonet is regulated into the shallow concave bayonet after being fixed, and the needle core is retracted into the needle tubing. A sufficient space is reserved for the biopsy and the needle core does not need to be totally pulled out. The operation process is simplified. The stability and the success rate of puncturing are improved.
Description
Affiliated technical field
This utility model discloses a kind of novel myeloid biopsy needle, belongs to technical field of medical instruments.
Background technology
Clinical myeloid biopsy needle commonly used mainly is made up of needle tubing, connecting portion, nook closing member, handle at present, and nook closing member is connected with handle, connects through concavo-convex bayonet socket between needle tubing, connecting portion, handle.When bone marrow biopsy, earlier needle tubing, nook closing member, handle are connected, extract nook closing member after fixing, connecting portion is connected between needle tubing and the handle, complicated operating process, the biopsy success rate is on the low side, and it is painful to increase patient's body and mind.
Summary of the invention
Use the myeloid biopsy needle complicated operating process always in order to overcome, the shortcoming that the biopsy success rate is on the low side, this utility model provides a kind of novel myeloid biopsy needle.This myeloid biopsy needle is simple in structure, and is simple for production, and the flow process that simplifies the operation improves the stability and the success rate of puncture.
This utility model solves the technical scheme that its technical problem adopted: this novel myeloid biopsy needle is made up of needle tubing, nook closing member, handle, and nook closing member is fixedly connected with handle, is connected through the embedding of concavo-convex bayonet socket phase between needle tubing and handle.Dark, shallow two the recessed bayonet sockets of biopsy needle needle tubing tail end band; Convex clip mouth of handle front end band; Earlier the convex clip mouth is placed dark recessed bayonet socket during bone marrow biopsy, nook closing member is exposed to the biopsy needle tubing and is convenient to inserting needle, the convex clip mouth is adjusted in the scrobicula bayonet socket after fixing again; Nook closing member bounces back in the needle tubing, for biopsy leaves adequate space and need not to extract fully nook closing member.
The beneficial effect of this utility model is: regulate the position of nook closing member in needle tubing through the evolution of handle front end convex clip mouth between dark recessed bayonet socket of needle tubing tail end and scrobicula bayonet socket during bone marrow biopsy; Need not to extract fully nook closing member; The flow process that simplifies the operation improves the stability and the success rate of puncture.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Fig. 1 is a utility model myeloid biopsy needle needle tubing sketch map.
Fig. 2 is a utility model myeloid biopsy needle nook closing member sketch map.
Shown in the figure: 1. needle tubing, 2. needle tubing tail end, 4. dark recessed bayonet socket, 3. scrobicula bayonet socket, 5. nook closing member, 6. convex clip mouth, 7. handle.
The specific embodiment
In embodiment as shown in the figure, earlier nook closing member (5) is inserted needle tubing (1) and handle front end convex clip mouth (6) is placed the dark recessed bayonet socket (4) of needle tubing tail end (2) during bone marrow biopsy, nook closing member (5) exposes from needle tubing (1); Gripping handle (7) inserting needle, fixing back is returned and is removed nook closing member (5), and convex clip mouth (6) is placed scrobicula bayonet socket (3); Nook closing member (5) bounces back in the needle tubing (1); Gripping handle (7) inserting needle places dark recessed bayonet socket (4) with convex clip mouth (6) after pulling out pin again, and myeloid tissue is extruded.
