Description
Technical field
The present invention relates to technical field of medical instruments, more specifically a kind of retrieving foreign bodies in vivo pin and get object space method.
Background technology
At present, when contingency appears in tiny foreign body, when residuing in human body, as shell fragment, wood flour, metal fragment etc., way traditional is at present: mainly take the mode of open surgery to take out.Operation consent needs leading CT examination to locate foreign body, then operates on tiny foreign body.This traditional approach has some deficiency following, and CT examination belongs to radioexmination, harmful; The otch of open surgery is comparatively large, hemorrhage more; If less foreign body retains in soft tissue, due to the easily movement when performing the operation of its position, operation often more difficult taking-up, foreign body can only be remained in vivo, patient often needs again to perform the operation thus causes larger tissue injury to cause further damage to patient, second: when tiny foreign body is more, when kind complexity, particularly when slag and scum; Performing the operation will be more serious to the damage of human body, and no matter the picking of a little is bring misery to patient, or all will further strengthen to the difficulty that doctor increases operation.
Summary of the invention
The otch that the first object of the present invention is to overcome open surgery in prior art is comparatively large, hemorrhage more technical disadvantages, and proposes a kind of retrieving foreign bodies in vivo pin, and it has and alleviates tissue injury and accurately convenient and swift.
Retrieving foreign bodies in vivo pin of the present invention, it comprises syringe needle that head is acute triangle, is positioned at the pin heart at middle part and is positioned at the needle body of afterbody, described syringe needle comprises needle point and is positioned at the inner rear of described needle point and is close to the insulant of the upper and lower inwall of described needle point, has nook closing member to extend into described needle body inner until withstand insulant; The flexible part of stretching out needle body is provided with in the front end of described nook closing member, cavity is formed between described flexible part and described needle body lower surface, the inwall of described cavity front end is glued with and gets thing net, between below the afterbody of described flexible part over top and described needle point, be provided with breach.
In technique scheme: described nook closing member is close on the lower surface of described needle body, is provided with nook closing member handle at the afterbody of described nook closing member, described nook closing member handle is circumscribed with the high frequency electric knife of standard specifications.
In technique scheme: be fixed with rotation needle handle on described needle body afterbody.
In technique scheme: described flexible partial head is fixed on described insulant.
In technique scheme: be coated with at described needle body inwall and be brushed with insulating coating.
In technique scheme: described thing net of getting is elastic insulatedly get thing net.
The otch that the second object of the present invention is to overcome open surgery in prior art is comparatively large, hemorrhage more technical disadvantages, and propose a kind of retrieving foreign bodies in vivo pin get object space method.
A kind of retrieving foreign bodies in vivo pin of the present invention get object space method, the method comprises the steps:
1., first foreign body in vivo is located, is verified the particular location of foreign body under B ultrasonic guides;
2., open the outer high frequency electric knife being connected on the standard specifications on described nook closing member handle, use needle point to be punctured to around foreign body, make needle body front end indentation, there aim at foreign body;
3., nook closing member handle is advanced to make flexible bend portions, during the super many foreign bodies size of the size of part to be bent, keep state now, the direction started to foreign body rotates needle handle, the connected thing net annular of getting of flexible part is made to wrap foreign body, the high frequency electric knife of standard of closure specification subsequently;
4., pull out nook closing member handle and make to get thing net and tighten up near needle body as far as possible, then exit needle body slowly.
The present invention has following technological merit: 1, the present invention adopts flexible part and gets the prepared advantage finding foreign body and conveniently take out foreign body of thing web frame design tool.2, the present invention adopts nook closing member structure to have the advantage alleviating tissue injury when taking out foreign body.Choosing 3, on integral material of the present invention has good promotion and application prospect with outstanding process small foreign body in operation.
