Description
Technical field
The present invention relates to the field of medical instrument technology, especially a kind of circular anastomosis with 3D nail slot structure resist-nailed seat
Device.
Background technique
Stapler be medically use substitution manual suture equipment, main operational principle be using titanium nail to organize into
Row detachment is coincide, and stapler is similar to.According to the scope of application difference, can be divided mainly into skin stapler, alimentary canal (esophagus,
Stomach and intestine etc.) circular staplers, rectum coinciding equipment, circular hemorrhoid anastomat, anastomat for circumcision, blood vessel anastomat, hernia coincide
Device, lung stapler etc..
Existing disposable round or anorectal anastomat sewing work is completed by suturing nail, the suturing nail in nail bin
Stress is advanced in the nail slot of resist-nailed seat to be bent so that opposite skin histology is sutured, resist-nailed seat follow closely the arrangement of slot with
Form plays a key role the correct forming of suturing nail.Inside and outside existing circular staplers are carried out by nail slot to resist-nailed seat
Circle is staggered, and to improve haemostatic effect, such as Authorization Notice No. is CN203598003U, and authorized announcement date is in May, 2014
21, the patent of entitled " resist-nailed seat of stapler ", the corresponding two nail slots of same suturing nail were in staggered row on the resist-nailed seat
Column, the dislocation of two nail pins can effectively avoid intermediate crossbeam when forming, and suturing nail shapes latter two nail pin Heterogeneous Permutation and is conducive to
The clamping of tissue, haemostatic effect is good after coincideing, but the anastomosis staple of the structure is all the Type B nail of 2D plane, and Type B nail is easy to appear
Non-uniform situation is sutured, healing effect is influenced.
Summary of the invention
In order to overcome the shortcomings of that existing 2D plane Type B nail be easy to cause suture uneven, the present invention provides one kind to have
3D follows closely the circular staplers of slot structure resist-nailed seat, and resist-nailed seat is arranged to intersect nail slot structure, and titanium nail edge is allowed to intersect nail slot bending
Intersect at 3D curved surface and forms.
The technical solution adopted by the present invention to solve the technical problems is: a kind of circle with 3D nail slot structure resist-nailed seat
Stapler is provided with inside and outside two railway spike slot circles on resist-nailed seat including being provided with the nail bin of titanium nail and be provided with the resist-nailed seat of nail slot,
Every railway spike slot circle by several nail slot groups constitutes, follow closely slot group be uniformly arranged using resist-nailed seat center as the center of circle, each nail slot group by
The preceding nail slot and rear nail slot being staggered are constituted, and preceding nail slot and rear nail slot are arranged in parallel, and the trailing flank of preceding nail slot and rear nail slot
Leading flank in same straight line.
Further, the nail slot group inside and outside resist-nailed seat on two railway spike slot circles is arranged in parallel.
Further, nail slot both ends are provided with the arc groove with titanium nail outer wall cooperation.
Further, the bottom surface of preceding nail slot and the distance between the top surface of rear nail slot are a=0.2 ~ 0.5mm.
Further, nail slot group is provided with 14 ~ 16 groups.
The invention has the advantages that resist-nailed seat is arranged to intersect nail slot structure, allow anastomosis staple along intersection nail slot bending
At 3D curved surface intersect form, be conducive to control tissue it is blocked up when tension, it is ensured that suture safety；And 3D nail is than 2D staple number of columns
Lack, can be reduced the quantity for staying in anastomosis staple in human body, has the function that reduce foreign matter stimulation, to mitigate patient suffering.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is partial enlarged view at B in Fig. 1；
Fig. 3 is suture titanium nail schematic diagram of the invention.
1. resist-nailed seat in figure, 2. follow closely slot groups, follow closely slot before 3., and slot, 5. arc grooves, 6. titaniums nail are followed closely after 4..
Specific embodiment
As shown in Figure 1,3, a kind of circular staplers with 3D nail slot structure resist-nailed seat, the nail including being provided with titanium nail 6
The resist-nailed seat 1 of slot is followed closely in storehouse with being provided with, and inside and outside two railway spike slot circles is provided on resist-nailed seat 1, every railway spike slot circle is by several nails
Slot group 2 is constituted, and nail slot group 2 is uniformly arranged using 1 center of resist-nailed seat as the center of circle, and each nail slot group 2 is by preceding 3 He of nail slot that is staggered
Nail slot 4 is constituted afterwards, and preceding nail slot 3 and rear nail slot 4 are arranged in parallel, and the trailing flank of preceding nail slot 3 with follow closely the leading flank of slot 4 afterwards same
Straight line, the nail slot group 2 inside and outside resist-nailed seat 1 on two railway spike slot circles are arranged in parallel, and the both ends of preceding nail slot 3 and rear nail slot 4 are provided with
The arc groove 5 of 6 outer walls cooperation is followed closely with titanium, nail slot group 2 is provided with 14 ~ 16 groups.Nail slot group 2 on traditional resist-nailed seat 1 is followed closely by two
Slot is alternatively arranged composition on the same line, follows closely with getting after nail bin cooperation in the 2D plane of B font, but easily occurs suturing not
Uniform phenomenon, the resist-nailed seat 1 are staggered by the two nail slots that will be followed closely in slot group 2, and nail slot both ends are equipped with the outer wall with titanium nail 6
The arc groove 5 of cooperation, being squeezed in titanium nail 6 by nail bin has good guiding function in bending process, because of preceding nail slot 3 and rear nail slot
4 are staggered so that forming after titanium nail 6 in both ends intersect 3D structures, facilitate control tissue it is blocked up when tension, really
Suture safety is protected, and the structure being staggered can reduce the number of the arrangement of titanium nail 6, it is fewer than traditional 2D titanium 6 quantity of nail, it can subtract
The quantity for staying in titanium nail 6 in human body less has the function that reduce foreign matter stimulation, alleviates the pain of patient to a certain extent.
It, can will as shown in Fig. 2, bottom surface of preceding nail slot 3 and the distance between top surface of rear nail slot 4 are a=0.2 ~ 0.5mm
The setting of slot interval is followed closely, and can guarantee the cooperation intensity of nail slot group 2 and titanium nail 6, to improve the sewing effect to wound.
Described above to be merely exemplary for the purpose of the present invention, and not restrictive, those of ordinary skill in the art understand,
In the case where not departing from spirit and scope as defined in the appended claims, many modifications, variation or equivalent can be made, but all
It will fall within the scope of protection of the present invention.
