Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of linear anastomat suturing nail chamber structure.
Background technology
Linear seam cutting device is widely used in being used for wound suture, interior tissue suture and cutting in surgical operation, has
Two functions of suture and cutting, while wound suture is carried out, by unnecessary cutting tissue.Linear seam cutting device is generally comprised
Upper and lower two clamps, are oppositely arranged on the nail anvil and nail bin of upper and lower clamp front end, in nail bin and can simultaneously relative nail bin
Mobile ejector pin bar and cutting knife, transversely arranged in nail bin be provided with pushing slice of nail and suturing nail, ejector pin bar promotes ejector pin successively in order
Piece is simultaneously pushed suturing nail to nail anvil and is sutured, and cutting knife will be located at the tissue cut-out between nail bin and nail anvil.But market is existing
Linear cutting anastomat, cutting and suturing nail are all transversely arranged, but from for clinical application angle, after laterally suturing always without
Regulation keeps away the unstitched situation in top, causes bleeding, and what existing nail bin structure was all formed is all the nail of parallel arrangement, suture
When form parallel suture, have no idea for suture to form intersection point, so cause have forever a direction that bleeding occurs
Situation, brings operation risk, doctor to bring difficult treatment to patient.
Content of the invention
The shortcoming of prior art in view of the above, it is an object of the invention to provide a kind of linear anastomat suture nail bin
The front end of two parallel sutures can be coupled together, realize the suture of front end tissue, prevent bleeding in operation by structure.
For achieving the above object and other related purposes, the present invention provides a kind of linear anastomat suturing nail chamber structure, bag
Staple cartridge body is included, the staple cartridge body offers push broach groove along its length, cutter are installed in the push broach groove, described pushed away
One group of nail is each provided with the staple cartridge body of cutter groove both sides, is provided with one group of connection in the staple cartridge body in front of the push broach groove
Nail, is provided with nail pushing device in the staple cartridge body below the connection nail, and the nail pushing device upper end is provided with suturing nail mounting groove,
The nail pushing device rear portion is provided with ejection structure, and the cutter front portion is provided with the ejection part with the ejection respective outer side edges,
When the cutter move forward to nail pushing device, the ejection part promotes nail pushing device to move upwards by ejection structure.
Using said structure, between traditional two groups of parallel nail, be provided with one group of connection nail, the connection nail with
Two groups of nail front ends of push broach groove both sides form closure in front of push broach groove, and connection nail can be vertical with push broach groove, also may be used
To incline, the suturing nail in certain two groups of parallel nail is promoted by traditional pushing slice of nail, when using, two groups of parallel nail
Two groups of parallel sutures are correspondingly formed, and the connection nail for being located at push broach front of the slot is correspondingly formed the seam of a longitudinal direction or inclination
Zygonema, two parallel suture line front ends are coupled together, and form the suture of closure, so as to stitch the tissue in front of push broach groove
Close, prevent bleeding.
And the suturing nail connected in nail is promoted by nail pushing device, i.e., suturing nail is arranged in suturing nail mounting groove,
While cutter are pushed ahead, make nail pushing device release suturing nail upwards by the cooperation of ejection part and ejection structure, realize
The closure of connection nail inseam dowel, such structure are adapted with the operating habit of doctor.Easy to operate, not additional dynamic
Make.Wherein described fore-and-aft direction, be for operator, i.e., nail bin be oriented front.
As preferred：Two groups of nail of the push broach groove both sides are parallel with push broach groove, and the connection nail is at least one,
And, the both sides that connect nail two group nail respectively close to push broach groove both sides vertical with the push broach groove.
Connection nail may be disposed to the mode vertical with push broach groove, and wherein connection nail can be multiple, meet tissue seam
Close intensity requirement.
As preferred：Ejector pin groove is provided with staple cartridge body in front of the push broach groove, the ejector pin groove and the push broach groove
Connection, the nail pushing device is in the ejector pin groove, and can move up and down in the ejector pin groove.
During normality, nail pushing device is located at ejector pin groove lowest part due to Action of Gravity Field, when nail pushing device is cut when knife is promoted upwards
On the one hand motion, ejector pin groove also act as guide effect.
As preferred：The nail pushing device is that bulk, its outline are adapted with the connection nail, and the ejection structure connects
Nail pushing device rear lower is connected on, the ejection structure posterior end face is low early and high after inclined plane, the ejection part of the cutter front portion is
Low early and high after inclined plane.
Growing steadily for nail pushing device is realized by the inclined plane for cooperating, sewing effect is good.
As preferred：The ejection structure is voussoir or trapezoid block, and the ejection part is wedge shape.
As preferred：Finite place piece is set in the ejector pin groove, and the locating part is located at the nail bin of the ejection superstructure
In inner body wall, the locating part limits the distance that the ejection structure is moved up, while limit the ejection part moving forward
Distance.
Its range of movement is limited by locating part, hyperkinesia is damaged upwards to prevent nail pushing device.
As preferred：Just right in the middle part of the ejection part of the cutter and the ejection structure, the ejection structure is horizontal
Width of the width less than the nail pushing device.
As preferred：The connection nail is two, and two connection nail form splayed.
Two parallel sutures can equally be coupled together by the structure in suture, form the closure suture of front end.Should
Under structure situation, the shape of nail pushing device changes, but principle is constant, and the suturing nail in two connection nail is pushed away by same
Nail device is promoted, and the top of nail pushing device is also divided into splayed.
As preferred：The connection nail is obliquely installed relative to the push broach groove, and the both sides of the connection nail are leaned on respectively
Two groups of nail front ends of nearly push broach groove both sides.
Using incline by the way of can also realize closure suture, the structure of its nail pushing device with vertical when structure similar, simply
Appropriate inclination.
As described above, the invention has the beneficial effects as follows：Simple structure, use when, can be by two parallel sutures before
End couples together, and forms the suture of closure in front of push broach groove, so as to by the tissue apposition in front of push broach groove, prevent bleeding.
While cutter are pushed ahead, nail pushing device is made to release suturing nail upwards by the cooperation of ejection part and ejection structure, real
Now connect the closure of nail inseam dowel, such structure is adapted with the operating habit of doctor, simple to operate.
