Description
This utility model relates to the medical instruments field of medical science, relates to a kind of multi-functional pleural space puncture needle particularly.
In the prior art, do biopsy of pleura clinically and extract hydrothorax, the method that adopts is to carry out with biopsy of pleura pin and thoracentesis needle respectively usually.Though this method has convenient feasible advantage, has following shortcoming: the one, the purposes of its pin is single, and the biopsy of pleura pin can only be used to take the pleura living tissue, carries out diagnostic test and can not be with this pin extraction hydrothorax, empyema; Thoracentesis needle can only be used to extract hydrothorax and can not be used to take the pleura living tissue, if patient had both needed to do biopsy of pleura, needs to extract hydrothorax again, then must gradation puncture.The 2nd, gradation is punctured, medical worker's troublesome poeration, and labor intensity is big, the painful big and required expense height of patient; The 3rd, often puncture time of delay diagnosis, treatment because of gradation, its disease can not in time be diagnosed and treat, be unfavorable for patient's health rehabilitation early.
The purpose of this utility model is the shortcoming that overcomes above-mentioned biopsy of pleura pin and pleura puncture needle, a kind of multi-functional pleural space puncture needle is provided, it can be applicable to biopsy of pleura, be applicable to again to extract hydrothorax, empyema, and easy and simple to handlely, laborsaving save time, little, the required expense of patient's misery is low.
Task of the present utility model is by the improvement design to existing biopsy of pleura pin and pleura puncture needle, and the two technical scheme that combines is dexterously realized.Its major technique feature is that the endoporus place leaves chamfering on an end annulus of the trocar (1), the other end is provided with needle handle (2), have the croze (6) that matches with hitching post (3) on the nook closing member on it, one end of pleura crochet hook (4) exposes outside it by the trocar (1), its end is provided with needle point, crochet hook (4) by its needle point place is provided with briar tooth (7), and the other end is provided with bolt handle (5), and the nook closing member of locating by bolt handle (5) is provided with hitching post (3).When take out pleura crochet hook (4) in the trocar (1), its needle handle (2) locates to connect an end of switching control pilot (8), and its other end connects sebific duct (10), and switching control pilot (8) is provided with turn-button (9).
Its technical characterictic is that the through-hole diameter of its switching control pilot (8) is 1.5～2.0mm.
This utility model lean on the needle body of its needle point to be provided with briar tooth, and the endoporus place on the annulus of the trocar one end leaves chamfering because the pleura crochet hook is established in employing in the trocar, the one end is provided with needle tip; And the needle handle (2) that takes out crochet hook rear sleeve pin locates to connect the structural design of switching control pilot and sebific duct, so that it has is reasonable in design, simple in structure, it both can puncture, get biopsy, can extract hydrothorax, empyema with it again.Simultaneously because its inserting needle, thus easy and simple to handle, time saving and energy saving, painful little, the required expense of patient is low, and make its disease in time obtain diagnosis and treatment, the rehabilitation of the person of having wholesome effects.Being suitable for hospitals at different levels popularizes.
Concrete structure of the present utility model has following embodiment and accompanying drawing to provide.
Fig. 1 is the biopsy sampling state profile according to the pleural space puncture needle that the utility model proposes.
Fig. 2 is the extraction hydrops state profile according to the pleural space puncture needle that the utility model proposes.(not drawing among the empty needle figure)
Fig. 3 is that the A of Fig. 2 is to view.
Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3 according to the pleural space puncture needle that the utility model proposes.
This pleural space puncture needle comprises the trocar (1), and the one end is circular; The other end is provided with needle handle (2), has the croze (6) that matches with hitching post (3) on the crochet hook nook closing member on it, and crochet hook (4) one ends pass the trocar (1) and expose outside it, and its end is provided with needle point and briar tooth (7); The other end is provided with bolt handle (5), after biopsy is taked in puncture, needle handle (2) in the trocar (1) is gone up an end that connects switching control pilot (8), which is provided with turn-button (9), the other end of switching control pilot (8) connects sebific duct (10), and sebific duct (10) locates to connect an empty needle can extract hydrops or empyema (not drawing among the figure).The endoporus place leaves a chamfering on the annulus of the trocar (1) other end, passes through when taking a sample in order to crochet hook (as Fig. 2, shown in Figure 3).Turn-button (9) on the switching control pilot among the figure (8) is in opening state, its work process is as follows: during use, puncture in the end insertion trocar (1) with pleura crochet hook (4) earlier, its pin enters behind the thoracic cavity briar tooth (7) and hooks up after the biopsy of pleura tissue takes out, locate to connect immediately switching control pilot (8) at its needle handle (2), sebific duct (10) connects an empty needle, forward turn-button (9) to parallel position and can extract hydrops with switching control pilot (8), empyema, because of an end of the trocar (1) is circular, so avoid in long period drawing liquid process, stabbing lung tissue, safe and reliable.Behind the drawing liquid turn-button (9) is closed (turn-button (9) and the perpendicular position of switching control pilot (8)), drawing liquid finishes and takes out the trocar (1) again, promptly finishes a work process.
This utility model is reasonable in design, simple in structure, easy and simple to handle, time saving and energy saving, and the painful little required expense of patient is low, and patient is willing to accept, and is suitable for hospitals at different levels and popularizes.
