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 a kind of nail bin groupware of tubular binding strument of operation, belong to technical field of medical instruments.
Background technology
Tubular binding strument is the surgical instruments being widely used in surgery reconstruction of digestive tract, as US Patent No. 5205459 describes a kind of tubular binding strument, be made up of nail-head component and percussion assembly, the tissue that two sections of needs couple together is placed between the nail anvil of nail-head component and nail bin, adjustment nail anvil and nail bin position make it close and grip tissue, then pulling the trigger assembly percussion makes nail be shaped, and completes the connection of two sections of tissues.
Doctor is after the complete tubular binding strument of percussion, and particularly tubular type hemorrhoid Binding Instrument, it is not tight that " recovery stress " in order to anti-non-magnetic shim causes nail to be shaped, and often can hold percussion handle more than 30 seconds after firing, good to guarantee that nail is shaped.30 seconds continue firmly is required great effort concerning doctor very much, and improperly may cause operative failure because exerting a force.Because twice percussion process can cause excessive compression to nail, the good nail that makes originally to be shaped becomes deformity, and the security of mouth is sewed up in impact, carrys out risk to surgical band.
The applicant has applied for Chinese patent ZL201020664436.8 on December 16th, 2010, which disclose a kind of nail bin groupware with anti-secondary percussion insurance function, comprising nail bin and be arranged on the ejector pin seat interfixed in nail bin and pushing slice of nail, this pushing slice of nail being provided with the hangnail that at least one and nail bin surface engagement reset for limiting pushing slice of nail.Although this patent provides the function of anti-secondary percussion, bring a problem: the blade being namely fixed on the cutting knife on ejector pin seat is exposed to outside nail bin after bookbinding, likely can produce the risk of its hetero-organization of injury simultaneously.
Content described in above-mentioned patent is quoted as prior art by the present invention.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is the nail bin groupware proposing a kind of safe and reliable tubular binding strument.
Object of the present invention, will be achieved by the following technical programs:
A kind of nail bin groupware of tubular binding strument, the ejector pin seat comprising nail bin and be slidably arranged in nail bin and pushing slice of nail, described pushing slice of nail is provided with the hangnail that at least one and nail bin surface engagement reset for limiting pushing slice of nail, described ejector pin seat is fixed with cutting knife, 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 in its direction of motion.
Preferably, the interface arrangment between described pushing slice of nail and ejector pin seat is 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, guarantees the security of performing the operation; And pushing slice of nail is placed in outside nail bin after bookbinding, serve the effect of anti-secondary percussion.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of nail bin groupware when binding of tubular binding strument of the present invention.
Fig. 2 is the schematic perspective view of nail bin groupware after bookbinding of tubular binding strument of the present invention.
Detailed description of the invention
Present invention is disclosed a kind of nail bin groupware of tubular binding strument, as shown in Figure 1 and Figure 2, comprise nail barrel 11, be located at the nail bin 1 of nail barrel 11 far-end and the ejector pin seat 2 be arranged in nail bin and pushing slice of nail 3, and described ejector pin seat 2 is fixed with cutting knife 4.Consistent with prior art, described pushing slice of nail 3 is provided with at least one and nail bin 1 surface engagement and for limiting the hangnail (not shown) that pushing slice of nail 3 resets.Like this, pushing slice of nail is placed in outside nail bin after bookbinding, serves the effect of anti-secondary percussion.The applicant discloses in the prior art completely, does not repeat them here.
Feature of the present invention is: 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 in its direction of motion with ejector pin seat 2.As shown in Figure 2, after described tubular binding strument bookbinding, firing lock reset due to tubular binding strument can drive ejector pin seat 2 to move backward, and at this moment described pushing slice of nail 3 is stuck on nail bin 1 by hangnail and makes it without any motion, described like this pushing slice of nail 3 departs from its direction of motion mutually with ejector pin seat 2, and the cutting knife 4 be fixed on ejector pin seat 2 will return in nail bin 1, this prevents the generation that cutting knife 4 cuts the risk of its hetero-organization.
Interface arrangment between described pushing slice of nail and ejector pin seat is step clamping, or zigzag clamping.The present invention does not have concrete restriction to interface arrangment.All employing equivalents or equivalent transformation and all technical schemes formed, all drop within protection scope of the present invention.
The present invention, when assembling, first by cutting knife and the fixed installation of ejector pin seat, is then encased in nail barrel together; Then pushing slice of nail is snapped fit onto on ejector pin seat, finally nail bin is installed to 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, the ejector pin seat comprising nail bin and be slidably arranged in nail bin and pushing slice of nail, described pushing slice of nail is provided with the hangnail that at least one and nail bin surface engagement reset for limiting pushing slice of nail, described ejector pin seat is fixed with cutting knife, it is characterized in that: described pushing slice of nail is connected in the far-end of described ejector pin seat, described pushing slice of nail is provided with the hangnail of at least one and nail bin surface engagement; When described tubular binding strument is bound, described pushing slice of nail and ejector pin seat interfix in its direction of motion, after described tubular binding strument bookbinding, described ejector pin seat moves backward, described pushing slice of nail is stuck on described nail bin by hangnail, and described pushing slice of nail and described ejector pin seat mutually depart from its direction of motion.
2. the nail bin groupware of tubular binding strument according to claim 1, is characterized in that: the interface arrangment between described pushing slice of nail and ejector pin seat is step clamping.
