Abstract
The invention discloses a nail bin component of a circular tube type binding instrument. The nail bin component comprises a nail bin, a nail push seat and a nail push sheet. The nail push seat and the nail push sheet are arranged in the nail bin in a sliding mode, and the nail push sheet is provided with at least one barb which is matched with the surface of the nail bin and used for limiting recover of the nail push sheet. The nail push seat is provided with a cutter, and the nail push sheet is connected at the far end of the nail push seat in a clamping mode. When the circular tube type binding instrument is used for binding, the nail push sheet is mutually fixed with the nail push seat in the movement direction of the binding instrument. The nail bin component has the advantages that the cutter can return to the nail bin after the binding is finished, and safety of a surgery is ensured. The nail push sheet is arranged outside the nail bin so as to play a role of preventing secondary percussion.
Description
Technical field
The present invention relates to the nail bin groupware of the tubular binding strument that a kind of surgical operation uses, belong to technical field of medical instruments.
Background technology
Tubular binding strument is the surgical instruments that is widely used in surgery reconstruction of digestive tract, put down in writing a kind of tubular binding strument as US Patent No. 5205459, formed by 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, adjusting nail anvil and nail bin position makes it near grip tissue also, then pull the trigger the assembly percussion nail is shaped, complete the connection of two sections tissues.
The doctor is after the complete tubular binding strument of percussion, and particularly tubular type hemorrhoid Binding Instrument, for " recovery stress " of preventing non-magnetic shim causes the nail shaping not tight, often can hold the percussion handle more than 30 seconds after percussion, and is good to guarantee the nail shaping.Lasting the exerting oneself of 30 seconds required great effort concerning the doctor very much, and may cause because the application of force is improper operative failure.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 impact, 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 be arranged on the ejector pin seat and the pushing slice of nail that interfix in nail bin, be provided with at least one on this pushing slice of nail and be used for limiting with the nail bin surface engagement agnail that pushing slice of nail resets.Although this patent provides the function of anti-secondary percussion, brings simultaneously a problem: the blade that namely is fixed on the cutting knife on the ejector pin seat is exposed to outside nail bin after bookbinding is complete, might produce the risk of its hetero-organization of injury.
The present invention quotes the content that above-mentioned patent is put down in writing as prior art.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the objective of the invention is to propose a kind of nail bin groupware of safe and reliable tubular binding strument.
Purpose of the present invention will be achieved by the following technical programs:
A kind of nail bin groupware of tubular binding strument, comprise nail bin and be slidably arranged in nail bin interior ejector pin seat and pushing slice of nail, be provided with at least one and nail bin surface engagement on described pushing slice of nail and be used for the agnail that the restriction pushing slice of nail resets, be fixed with cutting knife on described ejector pin seat, described pushing slice of nail is connected in the far-end of described ejector pin seat, and when described tubular binding strument is bound, described pushing slice of nail and ejector pin seat interfix on its direction of motion.
Preferably, the interface arrangment between described pushing slice of nail and ejector pin seat is the step clamping.
Compared with prior art, beneficial effect of the present invention is mainly reflected in: cutting knife can return in nail bin after bookbinding is complete, guarantees the safety of performing the operation; And pushing slice of nail is placed in outside nail bin after bookbinding is complete, 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 tubular binding strument of the present invention.
Fig. 2 is the schematic perspective view of nail bin groupware after bookbinding is complete of tubular binding strument of the present invention.
The specific embodiment
The present invention has disclosed a kind of nail bin groupware of tubular binding strument, as shown in Figure 1 and Figure 2, comprises nail barrel 11, is located at the nail bin 1 of nail barrel 11 far-ends and is arranged on nail bin interior ejector pin seat 2 and pushing slice of nail 3, is fixed with cutting knife 4 on described ejector pin seat 2.Consistent with prior art, be provided with at least one and nail bin 1 surface engagement on described pushing slice of nail 3 and be used for the agnail (not shown) that restriction pushing slice of nail 3 resets.Like this, pushing slice of nail is placed in outside nail bin after bookbinding is complete, has played the effect of anti-secondary percussion.The applicant discloses in the prior art fully, does not repeat them here.
Characteristics of the present invention are: described pushing slice of nail 3 is connected in the far-end of described ejector pin seat 2, and as shown in Figure 1, when described tubular binding strument is bound, described pushing slice of nail 3 interfixes on its direction of motion with ejector pin seat 2.As shown in Figure 2, after described tubular binding strument bookbinding is complete, can drive ejector pin seat 2 and move backward because the firing lock of tubular binding strument resets, and at this moment described pushing slice of nail 3 is stuck in by agnail and makes it without any motion on nail bin 1, described like this pushing slice of nail 3 breaks away from its direction of motion mutually with ejector pin seat 2, and the cutting knife 4 that is fixed on ejector pin seat 2 will return in 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 described pushing slice of nail and ejector pin seat is the step clamping, or the zigzag clamping.The present invention does not have concrete restriction to interface arrangment.All employing equivalents or equivalent transformation and all technical schemes of forming are within all dropping on protection scope of the present invention.
The present invention first with cutting knife and the fixed installation of ejector pin seat, then is encased in nail barrel when assembling 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 nail barrel.
Claims (2)
1. the nail bin groupware of a tubular binding strument, comprise nail bin and be slidably arranged in nail bin interior ejector pin seat and pushing slice of nail, be provided with at least one and nail bin surface engagement on described pushing slice of nail and be used for the agnail that the restriction pushing slice of nail resets, be fixed with cutting knife on described ejector pin seat, it is characterized in that: described pushing slice of nail is connected in the far-end of described ejector pin seat, and when described tubular binding strument is bound, described pushing slice of nail and ejector pin seat interfix on its direction of motion.
2. the nail bin groupware of tubular binding strument according to claim 1, it is characterized in that: the interface arrangment between described pushing slice of nail and ejector pin seat is the step clamping.
