Abstract
The utility model relates to a unilateral suture nail bin of a cutting anastomat, which belongs to the technical field of medical instruments and comprises a bin body and a sliding part, wherein the bin body is provided with a push knife groove and a plurality of nail outlet holes, and the nail outlet holes are distributed along the push knife groove; the sled can be configured in a cartridge body that contains staples on either the left or right side of the pusher slot and includes a cam member for firing the staples and a guide member. The utility model discloses only be equipped with the anastomosis nail in the unilateral of the storehouse body, only can carry out the unilateral during the use and sew up to can remain the tissues such as blood vessel of opposite side.
Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to nail storehouse is sewed up to unilateral of cutting anastomat.
Background
The existing various staplers and anastomats work on the same principle as the stapler. Namely, two rows of staggered staples are implanted into the tissue by percussion, and the tissue is cut and closed by double-row crossed staples, so that the suture is tight and the leakage is prevented.
The cutting anastomat is matched with a nail bin which is a disposable article for use. The nail bin comprises a bin body and a sliding part, and the bin body is provided with a push knife groove and a nail outlet hole. A sled can be configured in the cartridge body, the sled including a cam member for firing the staples and a guide member.
The sled of prior staple cartridges is provided with cam members on both the left and right sides of the guide member. Therefore, the existing cutting anastomat can be used for suturing on both sides, and only one side of the anastomat needs to be sutured for partial conditions (for example, when the living liver is transplanted for cutting the liver, the length of the blood vessel of a donor is limited), the blood vessel on the other side is reserved, the using amount of the artificial blood vessel is reduced, the risk is high after the artificial blood vessel is used, thrombus easily grows, anticoagulation is needed, and the medicine is taken for a long time; moreover, vascular prostheses are expensive.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a nail storehouse is sewed up to unilateral of cutting anastomat, can be used to carry out the unilateral to the cutting tissue under special circumstances and close.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the single-side sewing nail bin of the cutting anastomat comprises a bin body and a sliding part, wherein the bin body is provided with a push knife groove and a plurality of nail outlet holes, and the nail outlet holes are distributed along the push knife groove;
the sled can be configured in a cartridge body that contains staples on either the left or right side of the pusher slot and includes a cam member for firing the staples and a guide member.
Wherein the cam member includes a first cam wedge and a second cam wedge arranged side-by-side and at an interval.
Further, the slider is integrally manufactured.
Wherein, nail outlet holes are arranged on both sides of the push-knife groove.
Or the left side or the right side of the knife pushing groove is provided with a nail outlet hole, and the nail outlet hole and the anastomosis nail are positioned on the same side.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses only be equipped with the anastomotic nail in the unilateral of the storehouse body, only can carry out the unilateral during the use and sew up to can remain the tissue such as blood vessel of opposite side, ensure the usability of surplus tissue.
Drawings
FIG. 1 is a schematic view of the first embodiment of a cartridge body;
FIG. 2 is a schematic view of the structure of the slider;
fig. 3 is a schematic structural view of the cartridge body in the second embodiment.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.
Example one
As shown in fig. 1 and 2, the single-sided suture nail magazine of the cutting stapler disclosed in the first embodiment includes a magazine body 1 and a slider 2, the magazine body 1 is provided with a pusher slot 11 and a plurality of nail outlet holes 12, and the plurality of nail outlet holes 12 are arranged along the pusher slot 11. In the present embodiment, as in the prior art, nail outlet holes 12 are distributed on both sides of the push broach slot 11, but staples are only installed on the left side or the right side of the push broach slot 11.
The slides 2 can be arranged in the cartridge body 1. The sled 2 comprises a guide member 21 and cam members for firing staples, the guide member 21 being provided with cam members on the left and right sides. The cam member includes a first cam wedge 22 and a second cam wedge 23 arranged side-by-side and spaced apart. The slider 2 in this embodiment is manufactured integrally.
In use, the cartridge is mounted on a cutting stapler and staples mounted on either the left or right side are fired as the sled 2 is linearly translated through the cartridge body 1 to form finished staples in tissue on a single side.
Compared with the prior art, the stapling nail is only arranged on one side of the staple box, so that only tissue on one side is sutured, and tissues such as blood vessels on the other side are reserved.
Example two
The difference between this embodiment and the first embodiment is: as shown in fig. 3, in the present embodiment, nail outlet holes 12 are distributed on the left side or the right side of the knife pushing groove 11, and the nail outlet holes 12 are located on the same side as the staples.
Of course, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and that such changes and modifications are intended to be included within the scope of the appended claims.
