Abstract
The invention provides a guiding device used for being mounted at the front end of a medical anastomat to guide the anastomat into a human body. The guiding device is provided with a spiral body formed by strip-shaped guiding pieces in a surrounding mode, the spiral body is provided with a far end with a small diameter and a near end with a large diameter, the spiral body is wrapped by a flexible film which is provided with a traction end close to the far end, and the traction end penetrates out of the near end from a cavity in the spiral body. After the anastomat is guided into the human body, the guiding device can be taken out conveniently and can not exacerbate uncomfortableness of a patient.
Description
Technical field
The present invention relates to technical field of medical instruments, relate in particular to for the anastomat guiding being entered the guiding device of human body.
Background technology
Tubular binding strument is a kind of surgical instruments that tubular type is organized seaming and cutting operations that is widely used in, and is comprised of nail-head component and the percussion assembly of circle; The tubular type tissue that two sections needs are coupled together is placed between the nail anvil and nail bin of nail-head component, adjusts the distance of nail anvil and nail bin and comes grip tissue gradually, and then operation percussion assembly is shaped nail, completes the connection of two sections tissues.
In the operation technique of reality, there is the tubular binding strument of two kinds of operations to enter pipeline more difficult, be respectively low rectal operation and gastric bypass operation.The first low rectal operation, employing be that diameter is the tubular binding strument of 33 millimeters nail bins, need per anum to perform the operation.Because anus is a flesh opening, its diameter of normal condition is less, the major diameter apparatus is inserted into anus more difficult.The second gastric bypass operation, employing be that diameter is the tubular binding strument of 25 millimeters nail bins, need enter small intestinal and perform the operation.Be the digester tube of human body due to small intestinal, inwall has a lot of mucosas, and tubular binding strument is larger due to end face, and sufficiently oily due to the reasons in structure surface, walks in small intestinal easily to the mucosa injury.
The prior art that addresses the above problem at present is the several assistive device that is set in tubular binding strument nail bin groupware periphery that U.S. Patent application US20090204108 and US20110114698 disclose, nail bin groupware that can the tubular Binding Instrument of aimming circle enters human body and passes intestinal, can lay down this assistive device from nail bin groupware after it arrives the precalculated position of performing the operation, not affect the subsequent operation of tubular binding strument.These assistive devices can help the doctor that the head of Binding Instrument is successfully put into preposition, but this assistive device need use larger power to tear hauling-out at present, and easily accidental injury tissue and experience are not good.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of guiding device, it is after the guided anastomosis device enters human body, and conveniently self-fitting device front end takes out, and can not add heavy patient's discomfort.
For achieving the above object, guiding device of the present invention, the front end that is used for Medical stapler enters human body with the guided anastomosis device, described guiding device has guiding piece by strip around the spirillum that forms, described spirillum has the less far-end of diameter and the larger near-end of diameter, described spirillum is coated with fexible film, and fexible film has traction end near described far-end, and the cavity of described traction end in described spirillum extends described near-end.
As a further improvement on the present invention, the cross section of described guiding piece comprises internal layer and skin for staggered stacked two-layer parallelogram sturcutre.
As a further improvement on the present invention, described fexible film has elasticity, is strutted by elasticity in the time of outside being coated on spirillum.
As a further improvement on the present invention, described spirillum near-end is connected with and pulls part.
As a further improvement on the present invention, in two parallelogram sturcutres on the cross section of described guiding piece, be acute angle away from the drift angle of internal layer and outer field overlapping.
As a further improvement on the present invention, described fexible film original state is cylindrical shape.
As a further improvement on the present invention, described composition internal layer is identical with outer field parallelogram sturcutre.
Compared with prior art, guiding device of the present invention after the guided anastomosis device enters human body, can conveniently take out and can not add heavy patient's discomfort.

The specific embodiment
The present invention is described in detail below in conjunction with each embodiment shown in the drawings; but should be noted that; these embodiments are not limitation of the present invention; those of ordinary skills are according to these embodiments institutes work energy, method or structural equivalent transformation or substitute, within all belonging to protection scope of the present invention.
See also shown in accompanying drawing 1 to 6, guide body 100 is comprised of hard material, its cross section is the two-layer parallelogram structure that is crisscross arranged, comprise internal layer 101 and outer 102, the drift angle away from internal layer 101 and outer 102 overlapping on this internal layer 101 and outer 102 parallelogrames that form is acute angle.This guide body 100 can pull on part 200 around stacking, forms the whole spirillum 300 that is truncated cone-shaped, has cavity in spirillum 300.The less part of these spirillum 300 1 end diameters is far-end 301, and the part that diameter is larger is near-end 303.At this moment, the skin 102 that is in top guide body 100 is coated on internal layer 101 of its lower one deck guide body 100.Complete identically if form internal layer 101 and the parallelogram sturcutre that forms skin 102, the outer surface smoother of spirillum 300 can the scratch human body.
In use, guiding device 500 is arranged at the front end of anastomat (not shown), thereby the guided anastomosis device enters the assigned address of human body.The dilatory part 200 that pulls is pulled out the passage that spirillum 300 is in layer reserved in the self-fitting device to far-end 301 from near-end 303.After spirillum 300 was pulled out, fexible film 400 lost support, and pull traction end 401 this moment again, and the passage of reserving in described fexible film 400 self-fitting devices is pulled out.
Use guiding device of the present invention, because the special structure setting of guiding piece conveniently is stacked into spirillum, and pulls when pulling part in inside, facilitate despiralization.Guiding device of the present invention after the guided anastomosis device carries out operative site, can conveniently take out, and when taking out because guiding device self-fitting device is inner, can not add heavy patient's discomfort.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and in the situation that do not deviate from spirit of the present invention or basic feature, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, therefore is intended to include in the present invention dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limit related claim.
In addition, be to be understood that, although this description is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should make description as a whole, and the technical scheme in each embodiment also can through appropriate combination, form other embodiments that it will be appreciated by those skilled in the art that.
