Abstract

The utility model relates to a novel pleura cavity puncture needle, belonging to a medical apparatus field, comprising a needle point 1, a needle stalk 2 and a needle handle 3, characterized in that tail end of the needle point 1 is a blind end and provided with a miniature camera 4 for observing position of the puncture needle point 1 visually and accurately in a puncture process; and side surface of front end of the needle stalk 2 is provided with a side aperture 5, joint of the needle stalk 2 and the needle handle 3 is provided with a non-return valve 6, wherein the miniature camera 4 is connected with a data line 7 passing through the needle stalk 2 therein, and the tail end of the data line 7 is provided with a USB plug 8 for connecting a computer for imaging. The novel pleura cavity puncture needle is simple in structure and convenient in use, integrates puncture and imaging in one, can control position and depth of puncture effectively, and can prevent outside air from entering into pleura cavity thereby being favorable for maintaining balance of negative pressure in pleura cavity.

Description

Novel pleural space puncture needle

Technical field: this utility model belongs to medical instruments field, particularly a kind of novel pleural space puncture needle.

Background technology: in the clinical treatment activity, thoracentesis is a kind of basic skill operation, is used for internal organs focus biological tissue and gets inspection and pleural space aerofluxus, tapping etc.In piercing process, puncture needle need pass skin, subcutaneous tissue, muscle, multilayer tissues such as fascia, enter pleural space at last, because patient's age, height, body weight is had nothing in common with each other, the thickness of subcutaneous tissue and muscular fascia is also had nothing in common with each other, the degree of depth that in piercing process, is difficult to the assurance dynamics and thrusts, even under the mediation of X line, puncture successfully, also usually owing to inclined-plane inaccurate or that organize clot to stop up piercing needle, focus location carries out secondary puncture, after puncturing successfully, in aerofluxus tapping process, the medical worker needs repeatedly folder to close the conduit that is connected the needle handle place that punctures and enters pleural space to prevent ambient atmos, increased medical worker's workload, also brought unnecessary loss and misery simultaneously to the patient.

Summary of the invention: the purpose of this utility model is to provide a kind of collection puncture, images in one, can effectively control the position and the degree of depth of puncture, and can avoid ambient atmos to enter pleural space, help keeping the negative-pressure balancing of pleural space, novel pleural space puncture needle simple in structure, easy to use.

For achieving the above object, this utility model has been taked following technical scheme: this novel pleural space puncture needle, by needle point, pin stalk and needle handle constitute, the end of needle point is a cecum, and minisize pick-up head is installed, in piercing process, can be used to directly perceived, observe the position at needle tip place accurately, the side of pin stalk front end has side opening, and the pin stalk is provided with check valve with the junction of needle handle, can avoid ambient atmos to enter pleural space, help keeping the negative-pressure balancing of pleural space, minisize pick-up head connects data wire, and the data wire traveling is in the inside of pin stalk, the data wire end is provided with USB plug, is used for connecting the computer imaging.

This utility model, simple in structure, easy to use, collection punctures, images in one, can effectively control the position and the degree of depth of puncture, and can avoid ambient atmos to enter pleural space, helps keeping the negative-pressure balancing of pleural space.

Description of drawings: the utility model is described in further detail below in conjunction with accompanying drawing.

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

With reference to accompanying

drawing

1,1, needle point, 2, pin stalk, 3, needle handle, 4, minisize pick-up head, 5, side opening, 6, check valve, 7, data wire, 8, USB plug.

The specific embodiment: this utility model, constitute by needle point 1, pin stalk 2 and needle handle 3, the end of needle point 1 is a cecum, and minisize pick-up head 4 is installed, the side that pin obstructs 2 front ends has side opening 5, and pin stalk 2 is provided with check valve 6 with the junction of needle handle 3, and minisize pick-up head 4 connects data wire 7, data wire 7 travelings are in the inside of pin stalk 2, and data wire 7 ends are provided with USB plug 8.

When using this utility model, earlier USB plug 8 is connected on the computer, opens video, operation is punctured routinely, in piercing process, in conjunction with the image that computer presents, the position at close observation needle tip 1 place, puncture successfully after, as the need tapping, insert drainage tube, and the connection drainage bag gets final product.
