Abstract
The utility model provides a matching sealing type trocar. The utility model is added with a sealing tube needle on the basis of the present trocar, and the sealing trocar is fixedly connected with a seat cap through the bottom of the needle core. The needle core is connected with a connective plug which can coordinate to slide and move along the core rod, and the connective plug and the seat cap are installed with the stretching type sealing sheath of the covering needle core. The sealing needle is connected with a needle seat by the connective plug, and the seat cap and the connective plug is matched to connect for the positioning. The utility model takes advantages of safe and convenient operation, saving the drug and apparatus without needing repeated sealing needle, extensive suiting range, in particular to playing the protection function of the coagulant-sensitive sufferer without affecting, which is a novel medical trocar.
Description
Technical field
This utility model relates to a kind of trocar in the medical apparatus and instruments.
Background technology
In known technology, the existing medical apparatus and instruments trocar mainly is made up of core pin, sleeve pipe, needle guard, Y type needle stand, isolating seal plug, connecting leg, interface tube and calparine cap, is exactly this structure as the scalp formula trocar.But the existing trocar need be used heparin fluid-tight pin in use repeatedly, envelope pin technology is complicated and difficulty is bigger, especially the anticoagulant autopath is restricted and to using comparatively inconvenience of remaining needle patient, if the envelope pin is improper or impact with normal saline and to put that let the acupuncture needle remain at a certain point assists the unobstructed potential danger that causes blood vessel embolism that has again.
Summary of the invention
This utility model is the above-mentioned technical problem that exists at the existing trocar, through the research of several repetition test, the technical scheme that is adopted is: on the basis of the existing trocar, design has increased the tube sealing pin, the tube sealing pin is connected by nook closing member bottom and interlocks the connection plug that can slide along the body of rod on the seat medicated cap, core bar of band recess, and being fitted with the telescopic sealing sheath of enclosure nook closing member on the medicated cap at Lian Sai and seat, institute consists of and cooperates the closed trocar that seals pin.Nook closing member adopts nonmetallic macromolecule medical material to make.During use, after with the retained needle puncture success, airtight connection of connection plug and needle stand of tube sealing pin.Treat that transfusion finishes, the advance seat medicated cap inserts in the needle cannula nook closing member and seals, and seat medicated cap and connection filled in is connected and locatees.Owing in needle cannula, inserted the airtight envelope pin of nook closing member, just do not need the reuse heparin liquid to seal pin repeatedly, can prevent the blood back blood coagulation effectively, the side effect of also having avoided heparin fluid-tight pin to bring, because nook closing member adopts the macromolecule medical material of nonmagnetic sheathed cable substance to make, remaining needle is not damaged patient and needle cannula again.Therefore; this utility model compared with prior art; has simple and safe operation; save medicine and utensil, do not need to seal repeatedly pin, be not subjected to the restriction of heparin liquid anticoagulation persistent period; can significantly reduce the plugging rate of remaining needle; applied widely,, be a kind of novel medical trocar especially to the also unaffected beneficial effect such as can play a protective role of anticoagulant autopath is arranged.
Description of drawings
Fig. 1 is this utility model embodiment concrete structure figure.
Fig. 2 is the johning knot composition that the new embodiment of this practicality seals pin.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail.
Embodiment as shown in Figure 1, this utility model comprises: needle stand 3, sleeve pipe 2, core pin, needle guard 1, isolating seal plug 4, connecting leg 9, interface tube 10 and tube sealing pin.It is characterized in that the seat medicated cap 8 that the tube sealing pin is connected and is with the female thread recess by nook closing member 6 bottoms, the company of wearing can be along the connection plug 5 of core bar slippage movingly on nook closing member 6 core bars, and the telescopic sealing sheath 7 that is fitted with enclosure nook closing member 6 on a connection plug 5 and a medicated cap 8 is formed.Be shaped on external screw thread on the connection cock body, the tube sealing pin is connected in the external oral area of needle stand 3 by its connection plug 5 external screw threads.When needing the envelope pin, advance seat medicated cap 8 makes nook closing member enter in the sleeve pipe 2 along the slippage of connection plug mesopore, and sleeve pipe 2 sealings, seat medicated cap 8 is foldable in seat medicated cap recess with nook closing member sheath 7, the recess female thread of seat medicated cap 8 and the external screw thread of connection plug 5 location that is connected, thus reach the purpose of sealing pin.
