Abstract

The utility model relates to an anvil, in particular to an anvil for binding machine, and relates to the medical equipment technical field. The utility model is characterized in that the cutting surface of the anvil is a triangle concave with the top of the triangle positioned downward. The design as above makes the lancet can not touch the anvil before the tissue is cut, which ensures that the outside force made by the surgeon is used only for cutting the tissue. When the lancet reaches the bottom of the triangle concave (i.e. the top of the triangle), the surgeon can easily break the anvil and ensure that the tissue is cut off completely. Compared with the prior anvil shaped like a Chinese character ''ji'', the utility model achieves the step-by-step effect in the cutting process, and the surgical effect of simultaneous cutting off of both the tissue and the anvil.

Description

Binding Instrument cutter anvil

Technical field

This utility model relates to a kind of cutter anvil, and especially a kind of Binding Instrument cutter anvil belongs to technical field of medical instruments.

Technical background

Surgical binding instrument is to use in the operation of surgical staplings such as gastrointestinal, anorectal, and its application target is a kind of advanced operating theater instruments as end-to-end anastomosis.What it adopted is the principle that is similar to stapler, in use, anastomosis staple is pushed by the tissue that coincide, and anastomosis staple is bending forming under the nail anvil effect, and inner simultaneously ring-like cutter cuts off excess tissue and cutter anvil, realizes that the smooth of tissue coincide.The existing cutter anvil that is installed in the Binding Instrument mostly is the cutter anvil of ", and cutter need cut off the cutter anvil when cutting and organizing together, is used for guaranteeing to be organized in this process being completely severed.Just brought following problem thus: cut off in the tissue in operation, the cutter anvil of traditional " need be simultaneously severed, and that is to say that the doctor wants simultaneously tissue, cutter anvil both to be cut off.This mode is concerning the doctor who implements operation, and the strength that needs is very big, tends to occur repeatedly exert oneself in the percussion process, has influenced the progress of operation, has also increased patient's misery.

Summary of the invention

The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of Binding Instrument cutter anvil is provided.

The purpose of this utility model realizes by following technical solution:

Binding Instrument cutter anvil, wherein, the cutting position of cutter anvil is the triangular shape recess, and the top of triangle is down.

The purpose of this utility model also can further realize by following technical measures:

Above-mentioned Binding Instrument cutter anvil, wherein, the degree of depth of described triangular shape recess is less than the maximum cutting distance of Binding Instrument.

Further, above-mentioned Binding Instrument cutter anvil, it is installed in the linear type Binding Instrument or above the side side type Binding Instrument.

Advantage of the present utility model is: by adopt the facet of triangular shape recess, make be organized in be cut before, cutter can't touch the cutter anvil, have guaranteed that the operative doctor externally applied forces only is used to cut and organize.After the bottom that cutter march to triangular notch was the top of triangle, the doctor is the amputation knife anvil easily, and guaranteed that tissue is cut fully.Compare traditional " cutter anvil, this utility model can reach incremental effect to cutting process, allows doctor's gas that needn't go to great pains just can reach the surgical effect that tissue and cutter anvil cut off simultaneously.

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.

Description of drawings

Fig. 1 is the profile of this utility model facet.

Among the figure: 1-cutter anvil; The 2-recess.

The specific embodiment

Binding Instrument cutter anvil as shown in Figure 1, wherein: the facet of cutter anvil 1 is a triangular shape recess 2, and the top of triangle is down; And the degree of depth of triangular shape recess 2 is less than the depth capacity of cutter cutting.This cutter anvil 1 is particularly useful for linear type Binding Instrument or side side type Binding Instrument.

Use this Binding Instrument cutter anvil, after finishing the bundle pocket, tissue places the opening part of the recess 2 of cutter anvil 1.When operation proceeds to cutting in the time of the stage, the doctor pulls the trigger handle, the cutter of Binding Instrument inside are pushed out, before the tissue that is in sheets is cut off, the blade of cutter can't touch cutter anvil 1, like this, the doctor just can all be used to strength cut and organize, and need not be comprehended the state of cutter anvil 1 before cutting fully at tissue.Because the facet of cutter anvil 1 is a triangular shape recess 2, and the top of triangle down, its degree of depth is cut distance less than maximum, so after tissue was cut fully, blade just began tangential cutter anvil 1.As shown in Figure 1, the bottom that cutter march to triangular notch 2 is after the top of triangle, and the doctor who implements operation gets final product light amputation knife anvil 1, and the tissue that also further guaranteed to be in sheets simultaneously is cut fully.Compare traditional " cutter anvil, this utility model can produce incremental effect for cutting process, allows the doctor that the implements operation strength that needn't cost a lot of money also can cut off tissue and cutter anvil simultaneously, guarantees that surgical effect successfully.

In addition to the implementation, this utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in this utility model scope required for protection.

Claims (2)

1, Binding Instrument cutter anvil is characterized in that: the cutting position of cutter anvil is the triangular shape recess, and the top of triangle down.

2, Binding Instrument cutter anvil according to claim 1 is characterized in that: the degree of depth of described triangular shape recess is less than the maximum cutting distance of Binding Instrument.
