Abstract

The invention discloses a surgical operation stitching instrument, which comprises a nail anvil assembly and a nail bin assembly, wherein a cutter slot is arranged in the surface of the nail anvil assembly along the axis of the nail anvil; nails and a nail pushing sheet, which is abutted against the nails and is used for pushing the nails to move, are arranged in the nail bin assembly; at least two rows of nail forming slots are outwards symmetrically arranged towards the two sides in the nail anvil from the cutter slot; the distance from the bottoms of the outer-row nail forming slots to the nail anvil surface is bigger than the distance from the bottoms of the inner-row nail forming slots to the nail anvil surface; and the nail bin surface and the nail anvil surface are formed on the same plane. The surgical operation stitching instrument disclosed by the invention has the beneficial effects that the bottoms of the nail forming slots are gradually increased towards the two sides from the cutter slot, so that different nail forming depths can be obtained by using the same stitching instrument, and therefore, not only can bleeding of endothelial tissues be stopped well, but also blood can be sufficiently supplied to the overlying tissues. Besides, the surgical operation stitching instrument has good practicability.

Description

A kind of surgical suturing set

Technical field

The present invention relates to a kind of suturing mechanism of surgical suturing set, belong to technical field of medical instruments.

Background technology

Surgical stapler is to be used in the stitching of tissue, comprises nail-anvil assembly and nail bin groupware, and passes the cutting knife that is used for cutting off tissue between described nail bin.Be provided with two to three nails in nail bin groupware, be correspondingly provided with the nail forming tank on nail anvil, be organized between nail bin groupware and nail anvil and sew up by nail, initial tissue stitching instrument be nail anvil face (nail anvil and tissue contact surface) with nail bin face (nail bin and tissue contact surface) at grade, after stitching, because the stitching of two to three nails is highly identical, well close the blood effect although have, but after being organized in stitching, good blood confession can not be arranged, be unfavorable for the healing of wound.

Afterwards, a kind of novel stiching instrument has appearred, as a kind of stiching instrument of CN200710126615.9 announcement, in the situation that the nail forming tank degree of depth is consistent, by adjusting the distance between nail anvil face and nail bin face, perhaps by changing the height of pushing slice of nail, be embodied as the difference of sprig height, thereby in the situation that it is effective to guarantee to close blood, good blood confession also can be arranged, still, such complex structure, technology difficulty is large, and cost is high.

Summary of the invention

The objective of the invention is to propose a kind of effectively stitching and can provide the surgical suturing set of good blood confession again.

Purpose of the present invention will be achieved by the following technical programs:

A kind of surgical suturing set, comprise nail-anvil assembly and nail bin groupware, described nail anvil surface offers the cutting knife groove along its axis, be provided with nail in described nail bin groupware and follow closely mobile pushing slice of nail with the promotion that is used for of its butt, offer at least two nail forming tank by the outside lateral symmetry of cutting knife groove in described nail anvil, the distance of nail anvil face is arrived to the distance of nail anvil face in the bottom of outer nail forming tank greater than the bottom of interior nail forming tank, described nail bin face and nail anvil face are at same plane.

Preferably, described nail forming tank has three rows, and the molding degree of depth of nail forming tank is put discharged to effluxing to present to set up by interior.

Beneficial effect of the present invention is mainly reflected in: it is high that the degree of depth of only following closely forming tank by adjustment just can change final one-tenth sprig, and the degree of depth of nail forming tank is to both sides by the cutting knife groove and increases progressively shape, so only need to use one stiching instrument, just can obtain different nail forming heights, can not only make the interior layer tissue of suture site close blood good, can also make the outer tissue of suture site that good blood confession is arranged, good effect is played in patient's organization healing.

The specific embodiment

Technology provided by the invention can be used for surgical suturing set as shown in Figure 1 and Figure 2, comprises the open surgery stiching instrument of Wicresoft's closer and Fig. 2 of Fig. 1.

Consistent with prior art, comprise nail anvil 11 and nail bin groupware, be provided with in described nail bin groupware nail 15 and with its butt be used for to promote nail 15 pushing slice of nail that move 14, particularly as shown in Figure 3, also comprise in nail bin for the cutting knife that cuts off tissue, and offer at the center of nail anvil 11 for the cutting knife groove 13 of placing cutting knife.

As shown in Figure 7, in nail anvil 11 by cutting knife groove 13 laterally the both direction symmetry offer at least two nail forming tank, near cutting knife groove 13 be interior nail forming tank 17, close nail anvil 11 outer walls is outer nail forming tank 16.

With reference to Fig. 4-Fig. 7, described outer nail forming tank bottom 161 distances to nail anvil face 111 are the molding degree of depth of outer nail forming tank 16, and namely the outer nail molding degree of depth is H2; Described interior nail forming tank bottom 171 distances to nail anvil face 111 are the molding degree of depth of interior nail forming tank 17, and the interior nail molding degree of depth is H1.

After being organized in stitching, the remaining tissue after sewing up is excised, if outer nail molding depth H 1 is equal to or less than interior nail molding depth H 2, namely easily cause blood for not enough.So, the present invention lines up moldeed depth degree H2 at home and abroad greater than the interior moldeed depth degree H2 that lines up, like this, same as under stiching instrument in use, can obtain different nail molding depth H 1, H2, the tissue that can guarantee internal layer can well close blood, organizes and well blood confession outer field simultaneously, also is conducive to the healing of organizing.

In the present invention, distinguish separately at grade at nail anvil face 111 and nail bin face 121, during molding, both can closely connect, and help the stitching of stiching instrument.In the situation that do not change nail anvil face 111 and nail bin face 121 molding flats, the bottom of outer nail forming tank 16 is higher than the bottom of interior row's forming tank 17, specifically as shown in Figure 3.

Certainly, as the second embodiment of the present invention, as shown in Figure 9, also can be as required, follow closely forming tank and be set to three rows, be interior nail forming tank 17, the second nail forming tank 18 laterally by cutting knife groove 13 respectively, outer nail forming tank 16, at this moment, in order to reach the demand of well closing blood and abundant blood supply, the bottom of the nail forming tank that is arranged to both sides by cutting knife groove 13 is and increases progressively state, namely in the 171, second nail forming tank bottom 181, nail forming tank bottom, outer nail forming tank bottom 161 is and increases progressively shape.

The present invention still has numerous embodiments, and more rows' nail forming tank and anastomosis staple for example can be arranged.All employing equivalents or equivalent transformation and all technical schemes of forming are within all dropping on protection scope of the present invention.
