Description
Technical field
The present invention relates to medical instruments field, more particularly to it is a kind of can avulsion sheath puncture guide.
Background technology
In modern medical service, drainage is that osculum is cut at the internal organs such as thoracic cavity, bladder, abdominal cavity by performing the operation mostly, then
Drainage tube is implanted into by incision site, the method is not only complicated, and great wound and certain disease are brought to patient
Pain is tormented, and want the change of illness state of Real Time Observation patient's incision site, in order to avoid the problem of cross-infection etc. occur newly.Therefore
A kind of new medical procedures are arisen at the historic moment to realize drainage --- guid needle is punctured, it includes covering sheath, is nested in the intrathecal pin of set
Core, after completing to puncture by nook closing member, internal nook closing member is taken out, outer cover sheath is left, and drainage tube then is penetrated into the intrathecal reality of set
Drainage tube is now implanted into, finally outer cover sheath is taken out.And in modern medical equipment, the rear end of most of drainage tubes is all swollen with one
Big joint, monitoring test is carried out for external other Medical Devices, therefore when using foregoing puncture guid needle, although can
So that drainage tube is implanted into thoracic cavity, bladder, the internal organs such as abdominal cavity by puncturing guid needle, but due to drainage tube rear end expand joint without
Method smoothly takes out outer cover sheath, and hence, limit the use of this kind of drainage tube, and it is certain to be that medical personnel located is brought
Puzzlement.
Therefore a kind of new puncture guid needle of offer is needed badly to solve the above problems.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of can avulsion sheath puncture guide, can be applied to various
The use of drainage tube.
In order to solve the above technical problems, one aspect of the present invention is：There is provided it is a kind of can avulsion sheath puncture
Guide, including cover sheath, be nested in the intrathecal nook closing member of set, it is overall in shaft-like, sheath both ends open is covered, rear end is expanded, by two valves
The sheath composition of flare, in the symmetrical both sides of the body of rod, is provided with groove, groove is provided with tearing port, connect along its length
The nearly body of rod, two valve sheathes sheath symmetric position close to each other are provided with a pair of buckles being mutually matched；The tip of nook closing member is solid
Body is expanded for what the sheath with set sheath matched in cone or three rhombohedreons, rear end.
In a preferred embodiment of the present invention, the direction in space and the direction one of body of rod upper groove between two valve sheathes
Cause, so that sheath is more prone to divide de- sheath.
In a preferred embodiment of the present invention, tearing port includes several apertures or threaded openings, if aperture, then
Small aperture on groove positioned at lever front end is bigger than the small aperture positioned at body of rod rear end, due to the aperture positioned at body of rod rear end
Close to sheath, and the small aperture of rear end is small and distribution is close so that when the buckle of sheath contacts with each other, the body of rod be more prone to by
Tear.
In a preferred embodiment of the present invention, the body that expands of nook closing member rear end is in round table-like, expands the shape and two valves of body
The shape of sheath matches.
In a preferred embodiment of the present invention, the tip of nook closing member protrudes from the front end of set sheath, because the tip of nook closing member is used
In puncture skin, therefore the length of set sheath is shorter than the length of nook closing member.
In a preferred embodiment of the present invention, buckle point pin thread and box, both are not in contact, if the shape of pin thread to
Outer protrusion, then the shape of box cave inward so that displacement is not likely to produce when both contact with each other, when pin thread is in contact with box
When, both inconsistent power can tear set sheath along its groove.
In a preferred embodiment of the present invention, the inner surface in sheath cross section is raised provided with several, and correspondence is in pin
The position that body is in contact with sheath cross section of expanding of core is provided with several second grooves so that nook closing member and set sheath coordinate it is close and
It is difficult for drop-off.
In a preferred embodiment of the present invention, the material of the set sheath and nook closing member is medical grade PP plastics or medical grade
ABS plastic.The material has good biocompatibility, physicochemical property, and allergy etc. is also easy to produce when being contacted with body fluid and tissue
Adverse reaction.
The beneficial effects of the invention are as follows：Simple in construction, cost of the invention is low, by covering the change of sheath structure so that the puncture
Guid needle is applied to various drainage tubes, even rear portion carries the drainage tube for expanding interface, and will be covered by the form of tear
Sheath takes out patient wound, and simple and easy to apply, wound is small, significantly reduces the ailing torment of patient.
