Its using method is: pull trigger 6 earlier and promote the interior positioning needle 5 of nail casket by positioning needle saddle 9, tissue is enclosed between nail supporting base 1 and the nail casket 2, advance nail casket guide card 13 that the nail casket is compressed tissue to nail supporting base simultaneously, after finishing this sealing and compressing operation, trigger resets, and then pulls the trigger 6 drive nail pushing device guide cards 7 interior titanium nail of percussion nail casket forward, titanium is followed closely passed tissue, and act on nail supporting base, as the stapler of common usefulness tissue is stitched together.The function of following closely casket here is to hold titanium nail, nail pushing device and positioning needle, usually require the nail casket not reuse, after crossing once, the nail casket that promptly will more renew is again operated, therefore require to be easy to dismounting between nail casket and the nail casket guide card, simultaneously, in order to sew up accurately, to require again to follow closely and want and accurately to locate after casket 2 is contained on the nail casket guide card 13.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of accurate localized surgical linear anastomat quick-changing type of nail casket that can make and follows closely the casket positioner when changing the nail casket fast.
The technical scheme that addresses the above problem is (referring to implementing illustration): this utility model is provided with the elbow (8) that opening makes progress at frame arm (11) front end, the rear wall that the elbow front end upwards bends body is provided with linear nail supporting base (1), the nail casket guide card (13) that is in transmission connection with rear portion trigger (6) is housed on the frame arm, nail casket guide card front end is equipped with nail casket (2), it is characterized in that: described nail casket (2) is sandwiched between two walls (13a) of nail casket guide card front end, elbow (8) bottom surface is provided with the linear guiding lug, nib or the groove (8a) of fore-and-aft direction, nail casket (2) bottom surface is attached on elbow (8) bottom surface movingly, and be provided with the elbow bottom surface on described guiding lug, nib or groove (8a) the convex-concave groove or the fin (2a) that close of scarf mutually.
Further scheme of the present utility model is: two walls (13a) that described nail casket guide card (13) front end is provided with are parallel to each other, and are sandwiched in that mutual convex-concave phase scarf closes connection between nail casket (2) sidewall between the nail casket guide card two parallel walls and nail casket guide card wall (13a) internal face.
During pilot nail casket (2), can be inserted between two walls (13a) of nail casket guide card front end, when being inserted into the end, when making nail casket (2) bottom surface be attached on elbow (8) bottom surface, the groove of nail casket bottom surface or fin (2a) promptly can cooperate to guiding lug, nib or groove (8a) convex-concave with the front and back on the elbow bottom surface, play left and right sides positioning action, when pulling trigger and make nail casket guide card drive the nail casket to advance, the nail casket can advance along lead lug, nib or groove (8a) of linear.
After the further scheme of this utility model nail casket inserts between the nail casket guide card two parallel walls and since between nail casket two side and the nail casket guide card wall internal face convex-concave mutually scarf close, therefore can play positioning action to following closely casket better.
This utility model can make the nail casket realize Fast Installation, and is located fast in Fast Installation, thereby guarantees to realize more accurately sewing up function.

The specific embodiment
This example is provided with the elbow 8 that opening makes progress at frame arm 11 front ends, the rear wall that the elbow front end upwards bends body is provided with linear nail supporting base 1, the nail casket guide card 13 that is in transmission connection with the rear portion trigger is housed on the frame arm, be provided with two parallel wall 13a at nail casket guide card 13 front ends, two parallel wall 13a elasticity are clamped the location convex surface 13b elasticity that is provided with on nail casket 2, the two parallel wall internal faces and are embedded in the concave surface 2b that is provided with on nail casket 2 two sides.
During pilot nail casket 2, be inserted between the two parallel wall 13a, and clamped by two parallel wall elasticity, after being inserted into the end, nail casket bottom surface cooperates with the guiding lug, nib convex-concave of elbow 8a bottom surface, convex surface 13b elasticity on the two parallel walls embeds in the concave surface 2b of nail casket two side, thereby will follow closely the casket location, and can advance along the guiding lug, nib 8a on the elbow when operation.
Referring to Fig. 5, Fig. 6, two wall 13a of this example nail casket guide card 13 front end settings are parallel to each other, nail casket 2 sidewalls with the convex-concave embedding structure mutually of nail casket guide card wall 13a internal face are: described nail casket guide card wall 13a is provided with from the downward open-minded seam 13c of top edge, nail casket 2 sidewalls are provided with the positioning convex 2c that can insert this seam that slits downwards, the positioning convex bottom is connected with the seam bottom interference fit of slitting, and this routine positioning convex 2c bottom and the seam 13c bottom of slitting all are the circle of enlarged-diameter.
When this example will be followed closely casket 2 and be inserted between the two nail casket guide cards 13, the positioning convex 2c on its sidewall can enter the open-minded seam 13c of nail casket guide card wall, be inserted into the end after, the rounded bottom elasticity of positioning convex embeds the rounded bottom of the seam that slits, interference fit connection between the two.
The above; it only is preferred embodiment of the present utility model; be not that this utility model is done any pro forma restriction; every foundation technical spirit of the present utility model all still belongs to the protection domain of technical solutions of the utility model to any simple modification, equivalent variations and modification that above embodiment did.
