Abstract
The utility model discloses a nail bin assembly of a circular pipe type nailing instrument, which comprises a nail bin as well as a nail pushing seat and a nail pushing slice which are arranged in the nail bin in a sliding mode, wherein at least one barb matched with the surface of the nail bin for limiting the reset of the nail pushing slice is arranged on the nail pushing slice, a cutter is fixedly arranged on the nail pushing seat, the nail pushing slice is connected on the far end of the nail pushing seat in a clamping manner, and the nail pushing slice and the nail pushing seat are mutually fixed in the movement direction when the circular pipe type nailing instrument is used for nailing. The nail bin assembly of the circular pipe type binding instrument has the beneficial effects that the cutter can return in the nail bin after the nailing is finished so that the safety of operations is ensured; and the nail pushing slice is placed outside the nail bin so as to play the role of secondary strike prevention.
Description
Technical field
This utility model relates to the nail bin groupware of the tubular type binding appearance that a kind of surgical operation uses, and belongs to technical field of medical instruments.
Background technology
The tubular type binding appearance is the surgical instruments that is widely used in the reconstruction of digestive tract operation; Put down in writing a kind of tubular type binding appearance like U.S. Pat 5205459; Is made up of nail-head component and percussion assembly, the tissue that two sections needs are coupled together is placed between the nail anvil and nail bin of nail-head component, and adjustment nail anvil and nail bin position make it near grip tissue also; Pull the trigger the assembly percussion then nail is shaped, accomplish the connection of two sections tissues.
The doctor is after percussion finishes the tubular type binding appearance, and particularly tubular type hemorrhoid Binding Instrument for " recovery stress " of preventing non-magnetic shim causes the nail shaping not tight, often can held the percussion handle tight in one's hands more than 30 seconds after the percussion, and is good to guarantee the nail shaping.30 seconds lasting exerting oneself required great effort concerning the doctor very much, and may cause operative failure because of the application of force is improper.Because twice percussion process can cause excessive compression to nail, make the good nail of original shaping become lopsided, the safety of mouth is sewed up in influence, comes risk to surgical band.
The applicant applied for Chinese patent ZL201020664436.8 on the 16th in December in 2010; Wherein disclosed a kind of nail bin groupware with anti-secondary percussion insurance function; Comprise nail bin and the ejector pin seat and the pushing slice of nail that interfix that are arranged in the nail bin, this pushing slice of nail is provided with at least one and the nail bin surface engagement is used to limit the agnail that pushing slice of nail resets.Though this patent provides the function of anti-secondary percussion, bring a problem simultaneously: the blade that promptly is fixed on the cutting knife on the ejector pin seat is exposed to after bookbinding finishes outside the nail bin, might produce the risk of its hetero-organization of injury.
The content that this utility model is put down in writing above-mentioned patent is quoted as prior art.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is the nail bin groupware that proposes a kind of safe and reliable tubular type binding appearance.
The purpose of this utility model will be achieved through following technical scheme:
A kind of nail bin groupware of tubular type binding appearance; Comprise nail bin and the ejector pin seat and the pushing slice of nail that are slidingly arranged in the nail bin; Said pushing slice of nail is provided with at least one and the nail bin surface engagement is used to limit the agnail that pushing slice of nail resets; Be fixed with cutting knife on the said ejector pin seat, said pushing slice of nail is connected in the far-end of said ejector pin seat, and said pushing slice of nail and ejector pin seat interfixed on its direction of motion when said tubular type binding appearance was bound.
Preferably, the interface arrangment between said pushing slice of nail and the ejector pin seat is the step clamping.
Compared with prior art, the beneficial effect of this utility model is mainly reflected in: cutting knife can return in the nail bin after bookbinding finishes, and guarantees the safety of performing the operation; And pushing slice of nail is placed in after bookbinding finishes outside the nail bin, has played the effect of anti-secondary percussion.
Description of drawings
Fig. 1 is the schematic perspective view of nail bin groupware when bookbinding of this utility model tubular type binding appearance.
Fig. 2 is the schematic perspective view of nail bin groupware after bookbinding finishes of this utility model tubular type binding appearance.
The specific embodiment
This utility model has disclosed a kind of nail bin groupware of tubular type binding appearance, like Fig. 1, shown in Figure 2, comprises nail tube 11, is located at the nail bin 1 of nail tube 11 far-ends and is arranged on ejector pin seat 2 and the pushing slice of nail 3 in the nail bin, is fixed with cutting knife 4 on the said ejector pin seat 2.Consistent with prior art, said pushing slice of nail 3 is provided with at least one and nail bin 1 surface engagement and is used to limit the agnail (not shown) that pushing slice of nail 3 resets.Like this, pushing slice of nail is placed in after bookbinding finishes outside the nail bin, has played the effect of anti-secondary percussion.The applicant discloses in the prior art fully, repeats no more at this.
The characteristics of this utility model are: said pushing slice of nail 3 is connected in the far-end of said ejector pin seat 2, and is as shown in Figure 1, and said pushing slice of nail 3 interfixed on its direction of motion with ejector pin seat 2 when said tubular type binding appearance was bound.As shown in Figure 2; After said tubular type binding appearance bookbinding finishes; Because the firing lock of tubular type binding appearance resets and can drive ejector pin seat 2 and move backward, and at this moment said pushing slice of nail 3 is stuck in by agnail and makes it not have any motion on the nail bin 1, and said like this pushing slice of nail 3 breaks away from its direction of motion with ejector pin seat 2 each other; And the cutting knife 4 that is fixed on the ejector pin seat 2 will return in the nail bin 1, has so just prevented that cutting knife 4 from cutting the generation of the risk of its hetero-organization.
Interface arrangment between said pushing slice of nail and the ejector pin seat is the step clamping, or the zigzag clamping.This utility model does not have concrete restriction to interface arrangment.All employing equivalents or equivalent transformation and all technical schemes of forming all drop within the protection domain of this utility model.
This utility model earlier with cutting knife and the fixed installation of ejector pin seat, is encased in the nail tube when assembling then together; Then pushing slice of nail is snapped fit onto on the ejector pin seat, at last nail bin is installed to the pushing slice of nail far-end and nail bin is fixedly connected with the nail tube.
Claims (2)
1. the nail bin groupware of a tubular type binding appearance; Comprise nail bin and the ejector pin seat and the pushing slice of nail that are slidingly arranged in the nail bin; Said pushing slice of nail is provided with at least one and the nail bin surface engagement is used to limit the agnail that pushing slice of nail resets; Be fixed with cutting knife on the said ejector pin seat, it is characterized in that: said pushing slice of nail is connected in the far-end of said ejector pin seat, and said pushing slice of nail and ejector pin seat interfixed on its direction of motion when said tubular type binding appearance was bound.
2. the nail bin groupware of tubular type binding appearance according to claim 1 is characterized in that: the interface arrangment between said pushing slice of nail and the ejector pin seat is the step clamping.
