Abstract

The invention discloses a drainage device for safe puncture. The drainage device comprises a drainage tube as well as a puncture body and a guide wire which can be accommodated in the drainage tube, wherein the puncture body is further provided with a cylindrical protective sleeve; and the puncture body can be collected in the protective sleeve when the guide wire is drawn back, and is taken out from the drainage tube together with the guide wire. According to the drainage device for safe puncture, a puncture function is added on the basis of the drainage tube; a design of a cutter blade of the puncture body reduces the pain degree of a patient to the greatest extent; puncture is facilitated; a user draws the puncture body through the drainage tube interior from the front end of the drainage tube after the puncture and performs follow-up operation; and the design of the protective sleeve further guarantees the puncture stability, and the cutter blade can also be collected into the protective sleeve so as to prevent the drainage tube from being cut by the cutter blade.

Description

A kind of safe puncturing drainage apparatus
Technical field
The present invention relates to a kind of medical sanitary apparatus, relate in particular to a kind of safe puncturing drainage apparatus.
Background technology
No matter drainage tube is in operative process, or in post-operative treatment or rehabilitation course, is all the most frequently used device.In the use of drainage tube, modal problem is exactly coming off of drainage tube.In order to address this problem, developed drainage tube in the fixture of body surface at present, but this fixture not only cost is high, install complicatedly, also can increase wound, cause that wound surface stress even infect.But no matter whether use this fixture, once drainage tube comes off, prior art is difficult to realize secondary puncture, and drainage tube is again implanted and located.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of safe, easy to operate safe puncturing drainage apparatus that puncture implants drainage tube that passes through.
Technical scheme: for achieving the above object, a kind of safe puncturing drainage apparatus of the present invention, comprises drainage tube and can be contained in puncture body and the seal wire in drainage tube.
Puncture body of the present invention comprises the tool rest being connected with seal wire one end, and the blade that is arranged on tool rest another side.
Described blade is that front end is the sphenoid shape of blade, toward rear end thickness, becomes gradually greatly, and this design can reduce the pain of patient in piercing process, and puncture incision is little, is beneficial to healing.
As a further improvement on the present invention, the blade of described blade forms cambered surface at front end, in piercing process, can cut as required.
For convenient, seal wire is pulled out, described seal wire end is also provided with handle.
For safer operating environment is provided, prevent that blade cuts bad drainage tube when seal wire and puncture body are taken out from drainage tube tail end, described puncture body is also provided with a protective sleeve, this protective sleeve is tubular, one end opening of described protective sleeve is connected and installed with spiral cover by spiral, and the other end has the hole of passing through for seal wire; Described spiral cover have for described blade by so that be accommodated in the opening in protective sleeve; Described tool rest is spacing in protective sleeve by described spiral cover, is provided with shaft-like connector to realize the rotation of blade between blade and tool rest.When misfit with opening the position of blade rotation, spiral cover plays position-limiting action, facilitates blade punctures as in patient body; When the position of blade rotation is identical with opening, be seal wire rearward to be drawn to realize blade is taken in protective sleeve.The internal diameter of protective sleeve external diameter of the present invention and drainage tube is identical or be slightly less than the internal diameter of drainage tube.
As further optimization of the present invention, described spiral cover outer surface is provided with stopper slot, and the shape of described stopper slot is similar to blade cross section.When the position of blade rotation coincide with this stopper slot, blade can embed in stopper slot, can arbitrarily not rotate, and has further guaranteed the stability puncturing.
Puncture body of the present invention and seal wire are that metal material is made, and protective sleeve is also made for metal material, preferably take traditional stainless steel material as main.Utilize the advantage of metal material to be: reusable, sterilization can coordinate new drainage tube to use later; Metal material is convenient coordinates the B ultrasonic location of puncture, and raising degree of accuracy, has also reduced patient's misery.
Beneficial effect: safe drainage system of the present invention has increased puncture function on the basis of drainage tube, the insert design of puncture body reduces patient's distress level as far as possible, convenient puncture, after puncture, user is extracted from drainage tube front end puncture body out by seal wire through drainage tube is inner, carries out subsequent operation.The design of protective sleeve has further guaranteed the stability of puncture, also can prevent that blade from cutting bad drainage tube by blade being taken in protective sleeve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of seal wire of the present invention, puncture body and protective sleeve;
Fig. 3 is the using state figure of blade income protective sleeve;
Fig. 4 is the structural representation of spiral cover of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Please refer to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of safe puncturing drainage apparatus of the present invention, comprises drainage tube 1 and can be contained in puncture body 2 and the seal wire 3 in drainage tube 1.Seal wire 3 ends are also provided with handle 7.
In the present embodiment, puncture body 2 comprises the tool rest 4 being connected with seal wire 3 one end, and the blade 5 that is arranged on tool rest 4 another sides.Blade 5 is that front end is the sphenoid shape of blade 6, toward rear end thickness, becomes gradually large.The blade 6 of blade 5 forms cambered surface at front end.
Puncture body 2 is also provided with a protective sleeve 8, and this protective sleeve 8 is tubular, and an end opening of protective sleeve 8 is connected and installed with spiral cover 9 by spiral, and the other end has the hole 10 of passing through for seal wire 3; Spiral cover 9 have for blade 5 by so that be accommodated in the opening 11 in protective sleeve 8; Tool rest 4 is spacing in protective sleeve 8 by spiral cover 9, is provided with shaft-like connector to realize the rotation of blade between blade 5 and tool rest 4.Spiral cover 9 outer surfaces are provided with stopper slot 12, and the shape of stopper slot 12 is similar to blade 5 cross sections.
Puncture body of the present invention, seal wire and protective sleeve are all that metal material is made, convenient sterilizing, and position under B ultrasonic.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
