Abstract
The invention discloses an occlusion device for a linear excision anastomat for a surgical department. The occlusion device comprises a nail butting base, an assembly base, a nail butting base frame, an occlusion lead screw and a driving rod, wherein one end of the occlusion lead screw is connected with an occlusion knob, and the other end of the occlusion lead screw is provided with an occlusion nut in a movable mode; a driving pin is fixed on the occlusion nut; a first sliding chute matched with the driving pin is formed on the driving rod; two connecting rods are hinged on the nail butting base frame; an end of each connecting rod and the driving rod are hinged on a first pin shaft; the first sliding chute matched with the first pin shaft is formed on the nail butting base; a second pin shaft is also sleeved on the tail part of the nail butting base; and a second sliding chute matched with the second pin shaft is formed on the assembly base. By the occlusion device, the consistency of the occlusion height and inosculation height of apparatus on occlusion of physiological tissues is achieved, so the occlusion device can meet requirements of the physiological tissues with different thicknesses and ensures the surgical quality.
Description
Technical field
The present invention relates to a kind of surgery with the closing device of Linear cutting anastomat, belong to medical instruments field.
Background technology
At present, Linear cutting anastomat is a kind of medical apparatus and instruments that often uses when the physiological tissues such as digestive tract are performed surgical operation, but for stomach, when lung and intestinal tissue carry out cross-section identical excision, use existing Endo-GIA, there is following shortcoming: in the operation during closed compress tissue, balance closure before and after default price scissors realizes by apparatus, obvious stomach for different-thickness, lung, intestinal tissue, its counter-force to apparatus is different, because the apparatus front end is cantilever design, the apparatus rigidity is relatively poor, for thicker tissue, nail supporting base can upwarp distortion, makes front end coincide the height H change greatly, simultaneously also skew about meeting, cause the anastomosis staple cob webbing, the tissue that can't effectively coincide, impact operation quality is brought impact to operation safety; For identical different tissue, because individuality or histological difference, identical height is different in addition, in case selected apparatus, the shut height of prior art can't be adjusted, like this in clinical operation, might weigh tissue wounded, or it is highly bigger than normal to coincide, impact operation quality.Find that after deliberation these shortcomings mainly are owing to the design defect of surgery with the closing device of Linear cutting anastomat causes.
Summary of the invention
The purpose of this invention is to provide a kind of identical surgery that highly unanimously reaches the anastomosis staple forming quality in front and back closing device of Linear cutting anastomat that guarantees.
The technical scheme that realizes the object of the invention is: a kind of surgery closing device of Linear cutting anastomat, it comprises nail supporting base, assembly seat, the nail supporting base frame, closed screw mandrel and drive rod, one end of closed screw mandrel is connected with closed knob, the other end is equipped with closed nut movably, be fixed with drive pin on the closed nut, have the first chute that cooperates with this drive pin on the drive rod, be hinged with two connecting rods on the nail supporting base frame, one end of connecting rod and drive rod are hinged on the first bearing pin, have the 4th chute that cooperates with this first bearing pin on the nail supporting base, the afterbody of nail supporting base also is set with the second bearing pin, has the second chute that cooperates with this second bearing pin on the assembly seat.
Further, the afterbody of described drive rod is set with the 3rd bearing pin, has the 3rd chute that cooperates with the 3rd bearing pin on the nail supporting base.
Further, described closed nut and described nail supporting base frame are slidingly matched.
After having adopted technique scheme, realize the shut height of apparatus in closed physiological tissue and the concordance of the height that coincide, and can adapt to the requirement of the physiological tissue of different-thickness, guaranteed the operation quality.

The specific embodiment
Content of the present invention is easier to be expressly understood in order to make, and the below is according to specific embodiment and by reference to the accompanying drawings, and the present invention is further detailed explanation,
Shown in Fig. 1 ~ 3, a kind of surgery closing device of Linear cutting anastomat, it comprises nail supporting base 1, assembly seat 2, nail supporting base frame 3, closed screw mandrel 4 and drive rod 5, one end of closed screw mandrel 4 is connected with closed knob 7, the other end is equipped with closed nut 8 movably, be fixed with drive pin 9 on the closed nut 8, have the first chute 5-1 that cooperates with this drive pin 9 on the drive rod 5, be hinged with two connecting rods 6 by the 4th bearing pin 10 on the nail supporting base frame 3, one end of connecting rod 6 and drive rod 5 are hinged on the first bearing pin 11, have the 4th chute 1-1 that cooperates with this first bearing pin 11 on the nail supporting base 1, the afterbody of nail supporting base 1 also is set with the second bearing pin 12, has the second chute 2-1 that cooperates with this second bearing pin 12 on the assembly seat 2.
As shown in Figure 1, 2, the afterbody of described drive rod 5 is set with the 3rd bearing pin 13, has the 3rd chute 1-2 that cooperates with the 3rd bearing pin 13 on the nail supporting base 1.
As shown in Figure 4, described closed nut 8 is slidingly matched with described nail supporting base frame 3.
Operation principle of the present invention is as follows:
Put into the physiological tissue that will perform the operation in the apparatus of the present invention, rotating closed knob 7, drive closed screw mandrel 4 rotations, so that closed nut 8 is along the chute reach of nail supporting base frame 3, move by the drive pin 9 promotion drive rods 5 that are fixed on the closed nut 8, thereby drive two connecting rods 6 to lower swing, again because the cooperating of the second bearing pin 12 and the second chute 2-1, driving nail supporting base 1 can only move down abreast, physiological tissue is compressed to the identical height of requirement, shut height H is consistent before and after having guaranteed, so that coincideing, front and back highly kept concordance, because the self-locking performance of closed screw mandrel 4 and closed nut 8 can keep self-locking so that nail supporting base 1 presss from both sides on any position of closing physiological tissue downwards, adapted to physiological tissue's requirement of different-thickness again.
Above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
