Description
Technical field
This utility model belongs to medical instruments field, particularly relates to a kind of linear cutting anastomat.
Background technology
Disposable use linear cutting anastomat on existing market is a kind ofly can respectively squeeze into the staple that two rows intermesh on the both sides of tissue, and the tissue between staple line is carried out from disconnected apparatus simultaneously.In practice, likely can run into again the situation that former suture is sewed up again, but the linear cutting anastomat cutter that use in operation at present cannot be undertaken, from disconnected, to operation process, causing very large difficulty by having staple; And the material that the linear cutting anastomat staple of using in operation is at present used is pure titanium (material is softer), following requirements of operation staple is used titanium alloy material (material is harder with pure titanium ratio), but it is very painstaking that the ejector pin method of using disposable linear cutting anastomat is in the market squeezed into the staple of titanium alloy, be not easy to doctor's operation.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of linear cutting anastomat, make ejector pin in use procedure more laborsaving and can organize simultaneously and staple from disconnected.
For addressing the above problem, the technical scheme that this utility model adopts is as follows:
A kind of linear cutting anastomat, comprise upper cover plate, nail supporting base, lower cover, cover plate, middle clamp plate, handle pin, handspike, described upper cover plate is connected with described nail supporting base, described nail supporting base is fixedly connected with by described handle pin with described middle clamp plate, and described nail supporting base is provided with bracing frame and supports ailhead; Described handspike is arranged on described middle clamp plate and can on middle clamp plate, does linear slide; Described middle clamp plate is provided with cam and nail pushing plate parts, and described nail pushing plate parts comprise cutter and two symmetrical nail pushing plates, and described cutter are located at the centre of described two nail pushing plates, and described cutter are provided with a boss; Described middle clamp plate is provided with nail bin, and described nail bin is provided with medial launder; Also be provided with rolling bearing and shear blade, two ends, described rolling bearing axle center are fixedly connected on two nail pushing plate sidewalls, and described rolling bearing is arranged on described middle clamp plate and can on middle clamp plate, does straight-line rolling; Described shear blade is fixedly installed in described nail bin medial launder, corresponding with described cutter boss.
Preferably, described rolling bearing at least comprises 2.
Preferably, be also provided with flexible handle and cam pin, described flexible handle is located between described nail supporting base and middle clamp plate, and described cam is located at one end that described middle clamp plate is provided with handspike, and described cam is fixed on described middle clamp plate by described cam pin.
Compared to existing technology, the beneficial effects of the utility model are:
1, in this utility model, nail pushing plate becomes and slides as rolling under the effect of rolling bearing, has reduced the friction with middle clamp plate, makes ejector pin process more laborsaving;
2, this utility model utilizes shear blade and cutter to form scissor construction, becomes and cuts as cutting, and makes to organize cutting process more smooth;
3, this utility model utilizes shear blade and cutter to form scissor construction, can directly carry out, from disconnected, having strengthened the suitability of linear cutting anastomat, the upper use of being more convenient to perform the operation to staple in the past.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1, 2, this utility model relates to a kind of linear cutting anastomat, comprise upper cover plate 1, nail supporting base 2, lower cover 3, cover plate 4, middle clamp plate 5, handle pin 6, handspike 7, described upper cover plate 1 is connected with described nail supporting base 2, described nail supporting base 2 is fixedly connected with by described handle pin 6 with described middle clamp plate 5, and described nail supporting base 2 is provided with bracing frame 8 and supports ailhead 9; Described handspike 7 is arranged on described middle clamp plate 5 and can on middle clamp plate 5, does linear slide; Described middle clamp plate 5 is provided with cam 10 and nail pushing plate parts, and described nail pushing plate parts comprise cutter 11 and two symmetrical nail pushing plates 12, and described cutter 11 are located at the centre of described two nail pushing plates 12, and described cutter 11 are provided with a boss; Described middle clamp plate 5 is provided with nail bin 13, and described nail bin 13 is provided with medial launder; Also be provided with rolling bearing 14 and shear blade 15, described rolling bearing 14 two ends, axle center are fixedly connected on two nail pushing plate 12 sidewalls, and described rolling bearing 14 is arranged on described middle clamp plate 5 and can on middle clamp plate 5, does straight-line rolling; Described shear blade 15 is fixedly installed in described nail bin 13 medial launders, corresponding with described cutter 11 boss, forms scissor construction, during use, tissue or staple under the combined effect of cutter boss blade and shear blade blade from breaking.In preferred version, described rolling bearing at least comprises 2.Linear cutting anastomat is also provided with flexible handle 16 and cam pin 17, described flexible handle 16 is located between described nail supporting base 2 and middle clamp plate 5, described cam 10 is located at one end that described middle clamp plate 5 is provided with handspike 7, and described cam 10 is fixed on described middle clamp plate 5 by described cam pin 17.
