Abstract
The invention relates to an anastomat for surgical department. The anastomat comprises a casing, a center rod, a push pipe and a nail pushing sheet, wherein the head part of the push pipe is fixedly connected with the bottom surface of the nail pushing sheet, the top of the casing is provided with a nail cabin, suture nails are contained in the nail cabin, the center rod passes through the push pipe and can slide along the push pipe, the center rod extends out of the casing and is in an integral structure, and a nail butting seat is connected with the center rod through a D-shaped fixing hole. The anastomat has the advantages that the structure is simple, the positioning is accurate, the striking stability is high, and the anastomat cutting effect of the anastomat can be ensured; the assembly is convenient, and the use is safe and reliable.
Description
Technical field
The present invention relates to a kind of surgical anastomat.
Background technology
Anorectal anastomat, as the common tool in a kind of surgical operation, is widely used in coincided with human body tissue in operation process, particularly rectum distal site, is applicable to the suspention of the interior prolapse of rectal mucosa of anal canal or interior prolapse of hemorrhoid.Anorectal anastomat can reduce the suture time of tissue, improves suture strength, has reduced operating difficulty, has effectively protected the suture of pipe tissue, has improved operation quality, can significantly improve the healing effect of suture.
Existing medical surgery anastomat, can generally comprise housing, center-pole, ejector sleeve and pushing slice of nail with reference to Fig. 1, and ejector sleeve head and pushing slice of nail bottom surface are fixed together, and pushing slice of nail top is provided with nail bin, and nail bin is in-built suturing nail.Center-pole packs in ejector sleeve and can slide along ejector sleeve, and center-pole stretches out outside housing, and head is equipped with nail supporting base, and nail supporting base position is corresponding with nail bin.During operation, after the tissue wait performing the operation is drawn in nail bin cylinder cavity completely, screw anastomat, pull the trigger.Pushing slice of nail is close to nail supporting base, and suturing nail is correctly shaped.Nail supporting base is welded in center-pole end, bears the suturing nail required percussion force that is shaped, and percussion force is generally larger.Existing anastomat center-pole is to adopt Split type structure, as shown in Figure 2, by locating shaft 21 ' and screw rod 22 ', by pin 23 ', is formed by connecting.The concordance of this Split type structure assembling is poor, during percussion, can cause closure between suturing nail and nail supporting base not exclusively, to affect suturing nail and be shaped, and the identical and cutting effect in operation process is exerted an influence, and organizes hemorrhage while causing closure.
In addition, being connected between the nail supporting base of the anastomat of above-mentioned Split type structure and center-pole is achieved in that as shown in Figures 2 and 3, center-pole afterbody is pressed in nail supporting base center hole, by both position degree requirements of assurance such as frock clamps, the depth of parallelism of the assurance flat place of center-pole milling and nail supporting base is carried out laser spot welding after requiring.Because the end of center-pole is hierarchic structure, can produce larger loss like this, and center-pole is in assembling process, due to multiple bearing, there is accumulation position error, easily make nail supporting base and locating shaft location inaccurate, thereby cause nail bin hole dislocation on nail supporting base and nail bin, affect suturing nail and be shaped.
Summary of the invention
The object of this invention is to provide that a kind of center-pole is simple in structure, percussion stability is high, can guarantee the surgical stapling of anastomat osculating effect.
Technical scheme of the present invention is: a kind of surgical anastomat, comprise housing, center-pole, ejector sleeve and pushing slice of nail, ejector sleeve head and pushing slice of nail bottom surface are fixed together, and case top is provided with nail bin, and nail bin is in-built suturing nail, center-pole also can slide along ejector sleeve through ejector sleeve, center-pole stretches out outside housing, and nail supporting base is fixed on the end of center-pole, and nail supporting base position is corresponding with nail bin, it is characterized in that, center-pole is integrated.
Described center-pole is pressed into nail supporting base centre bore, and the two is fixed together by lock-screw, and nail supporting base position is corresponding with nail bin, and nail supporting base centre bore is " D " shape, " D " shape structure of center-pole end for matching with nail supporting base centre bore.
The invention has the beneficial effects as follows, adopt the integrated structure of center-pole, simple in structure like this, registration, percussion stability is high, can guarantee anastomat osculating effect.And easy to assembly, safe and reliable.Adopt " D " shape centre bore and the semi-circular projection mode that is connected, can reduce the wastage, the plane in " D " shape is as spline plane, and so, nail supporting base and nail bin are located completely, have guaranteed the correct shaping of suturing nail, and the stability of performing the operation is further promoted.

The specific embodiment
As shown in Figure 1 and Figure 4, surgical anastomat of the present invention, comprises housing 5, center-pole 2, ejector sleeve 4 and pushing slice of nail 6, and ejector sleeve 4 heads and pushing slice of nail 6 bottom surfaces are fixed together, pushing slice of nail 6 tops are provided with nail bin 3, nail bin 3 is in-built suturing nail, and center-pole 2 is through ejector sleeve and can slide along ejector sleeve, and center-pole 2 stretches out outside housing 5, the end of nail supporting base 1 welding and center-pole 2, nail supporting base 1 position is corresponding with nail bin 3, it is characterized in that, center-pole 2 is integrated.
As shown in Figure 1, Figure 4 and Figure 5, center-pole 2 is pressed into nail supporting base centre bore 11, and the two is fixed together by lock-screw, and nail supporting base 1 position is corresponding with nail bin 3, nail supporting base centre bore 11 is " D " shape, the semi-cylindrical hill of center-pole end 21 for matching with nail supporting base centre bore.Nail supporting base 1 please refer to Fig. 6 with the assembling of center-pole 2, after coordinating with the semi-cylindrical hill of center-pole end, fixes by lock-screw " D " shape centre bore of nail supporting base, reduced on the one hand the use of material, plane in semicircle can limit center-pole rotation on the other hand, improve the fitness between nail supporting base and center-pole, thereby nail supporting base and nail bin are located completely, guaranteed the correct shaping of suturing nail, the stability of operation is promoted greatly.
