Abstract
The utility model relates to a rotary knife anvil subassembly of a binding instrument for a surgical operation, which is a rotary ablation device and comprises a nail anvil cap, a nail anvil ring, a pullback spring and a knife anvil, wherein one end of the pullback spring is fixed on the nail anvil ring, one end is fixed at the inner side of the outer wall of the knife anvil, the knife anvil is fixed on the nail anvil ring and the inner wall of the knife anvil is provided with two holes which are rotated by an abdication pullback spring. The utility model has the advantages that a rotary cutting function is realized, the resistance of cutting tissues is reduced effectively, wounds stretched by the tissues caused by cutting are reduced, the tissue cutting is ensured safely and the binding force needed by an operation is reduced.
Description
Technical field
This utility model relates to the cutter anvil assembly of a kind of surgical operation with Binding Instrument, is in particular a kind of swivel knife anvil assembly of binding device for surgery.
Technical background
The stitching of surgical operation wound surface, the general means such as manual needlework are sewed up, gluing, slide fastener, Binding Instrument that adopt, wherein Binding Instrument is as operating wound surface suture instrument, more and more adopted by surgical operation, the cutter head of the binding device for surgery of prior art is in to wound face feeding bookbinding, its ring-like cutting knife is a straight-line feed, not only the surgeon need apply sizable strength and finish cutting, and cause the unnecessary cutting tissue of wound face unclean easily, cause actual bodily harm for the person of undergoing surgery.For this reason, on the cutter anvil, done a lot of improvement abroad mostly, but as ring-like amputation knife anvil, or on the cutter anvil, add the platform level; Also some improves on cutter, as ring-like blade being designed to zigzag at interval.But in the utilization of reality, all can not solve the unclean problem of unnecessary cutting tissue of the excessive and wound face of the application of force at all.
Summary of the invention
The purpose of this utility model is exactly the rotary cutter that the less binding device for surgery of a kind of unnecessary tissue that can thoroughly remove the wound face and the application of force is provided for the above-mentioned defective that solves prior art.
The purpose of this utility model realizes by following technical solution.
A kind of swivel knife anvil assembly of binding device for surgery, its cutter anvil assembly is the rotation device for excising, and the cutter anvil assembly includes nail-anvil cap, pin anvil ring, extension spring, cutter anvil, and an end of extension spring is fixed on the pin anvil ring, one end is fixed on cutter anvil outer wall inboard, and the cutter anvil is fixed on the pin anvil ring; The hole that two extension spring rotations of stepping down are arranged on the cutter anvil inwall.
Advantage of the present utility model is: 1, realize the rotation cutting function; 2, effectively reduce the resistance that cuts off tissue; 3, reduce because of what cut-out caused and organize tensile wound; 4, safety and reliability ground guarantees to cut off tissue; 5, reduce the bookbinding power of performing the operation required.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

The specific embodiment
Shown in Fig. 1-2, this utility model cutter anvil assembly is the rotation device for excising, and the cutter anvil assembly includes nail-anvil cap 1, pin anvil ring 2, extension spring 3, cutter anvil 4, and an end of extension spring 3 is fixed on the pin anvil ring 2, one end is fixed on cutter anvil 4 outer wall inboards, and cutter anvil 4 is fixed on the pin anvil ring 2; The hole 5 that two extension spring rotations of stepping down are arranged on cutter anvil 4 inwalls.Cutter anvil outer exterior wall has spacing block set 6, is provided with the groove 7 that cooperates with cutter anvil spacing block set on pin anvil ring 2, and groove 7 tops are provided with all annular rotary stopper scrobicular rings 8, and pin anvil ring 2 is connected with cutter anvil 4 outer walls.Run into cutter anvil 4 when cutting knife is advancing after, to pusher, simultaneously, the projection of cutter anvil 4 breaks away from the groove 7 of pin anvil ring, enters into scrobicular ring 8 cutter anvil 4.Cutter anvil 4 produces rotation under the effect of extension spring 3.
Or shown in Fig. 3,4, described cutter anvil 4 inwalls bottom is fixed on the pin anvil ring 2; Pin anvil ring 2 is connected with cutter anvil 4 outer walls.When cutting knife advancing and amputation knife anvil 4 after, cutter anvil 4 outer walls produce rotation under the effect of extension spring, inwall maintains static.
In addition to the implementation, this utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of this utility model requirement.
