Detailed description of the invention
Please refer to Fig. 1 to Fig. 3, the invention provides a kind of purse-string suture device with anvil structure, particularly disposable automatic purse-string suture device.
The purse-string suture device of described band anvil structure comprises: operating mechanism, comprises the first end and the second end that are oppositely arranged; Upper nail bin box 1, is connected with first end; Lower nail bin box 2, is connected with the second end; Nail anvil 3, is connected with the second end, and nail anvil 3 comprises body 4, and body 4 comprises the surface 5 of upper and lower two arcs, is provided with multiple nail forming tank 6 on each surperficial 5.Preferably, nail forming tank 6 comprises the groove in B font, thus suturing nail can be shaped to B font.Preferably, multiple nail forming tank 6 lines up side.Preferably, upper nail bin box 1 and lower nail bin box 2 are provided with wiring hole, for installing stitching thread.Preferably, upper nail bin box 1 is provided with wiring hole 20.
During use, in upper nail bin box 1 and lower nail bin box 2, suturing nail is installed, when by driving the suturing nail in upper nail bin box 1 and lower nail bin box 2 to the operation of operating mechanism to the direction percussion of nail anvil 3, the end of the suturing nail of pulling the trigger out contacts with the surface 5 of nail anvil 3, and be bent into closed shape (such as B font etc.) along nail forming tank 6, thus more firmly by fixing for suturing nail organizationally, tighten up the support that pocket provides strong, staple difficult drop-off for sewing up rope.Further, because nail anvil 3 has the surface 5 of upper and lower two arcs, thus, two layers of tissue separately can be sewed up separately simultaneously, solve suturing nail corresponding when sewing up in prior art through double-layered structure so that two layers of tissue staple problem together.
Visible, owing to have employed technique scheme, use suturing nail molding effect of the present invention to stablize, grab charge-coupled knitting firmly, monolayer organization can be realized and sew up, avoid the series connection that double-layered structure is sewed up.
Preferably, nail anvil 3 also comprises the fixed guide bonding part 7 of T-shaped, and one end of fixed guide bonding part 7 is connected with body 4, and lower nail bin box 2 is provided with nail anvil fixed part 8, and fixed guide bonding part 7 is locked in nail anvil fixed part 8.Like this, fixed guide bonding part 7 is installed on nail anvil fixed part 8, can realizes fixing the installation of nail anvil 3.
Preferably, nail anvil fixed part 8 has holddown groove 9, the sidewall of holddown groove 9 is formed with lock hole 10, and fixed guide bonding part 7 is arranged in holddown groove 9, and fixed guide bonding part 7 comprises the locking projection 11 snapped in lock hole 10.In this embodiment, after fixed guide bonding part 7 loads nail anvil fixed part 8 holddown groove 9, the locking projection 11 of fixed guide bonding part 7 snaps in the lock hole 10 of nail anvil fixed part 8, thus the installation of nail anvil 3 locking.
Preferably, purse-string suture device also comprises nail bin 12, is provided with a nail bin 12 in upper nail bin box 1 and lower nail bin box 2.Be placed with suturing nail in nail bin 12, nail forming tank 6 is evenly distributed on the position near the peripheral curved surface of nail anvil 3 head, keeps corresponding with the nail position of depositing suturing nail of nail bin 12.Preferably, the front of nail bin 12 becomes arc shape, to be consistent shape with the cambered surface of nail anvil 3.
Preferably, purse-string suture device also comprises the pushing block that the suturing nail for promoting in nail bin 12 moves to nail anvil 3 direction.Like this, by pushing block, just suturing nail being pulled the trigger, and evenly form B font by nail forming tank 6 and fix, more firmly tightening up for sewing up rope the support that pocket provides strong organizationally by fixing for suturing nail, and suturing nail difficult drop-off.Further, pushing block embeds nail bin inside together with suturing nail.
Preferably, operating mechanism comprises the first arm 13 and the second arm 14, first arm 13 and the second arm 14 hinged formation X-shaped structure, upper nail bin box 1 is connected with one end of the first arm 13, lower nail bin box 2 is connected with one end of the second arm 14, and the other end of the first arm 13 and the other end of the second arm 14 are all shaped to operating grip 15.In one embodiment, the first arm 13 is connected by bearing pin 19 pivotly with the second arm 14, forms jaw between the first arm 13 and described one end of the second arm 14.When operating operating grip 15, jaw can be made to open or close.
Preferably, operating mechanism also comprises insurance 16, is connected with the first arm 13 and the second arm 14.Only when opening insurance 16, during ability normal operating operating grip 15, jaw can be made to open or close, thus improve safety of the present invention.
