It is equipped with hanging ring 30.
In the use of the present invention, being entered by the opening on skin intraperitoneal, sewing work is carried out to internal wound, is led to
The curved shape that control mechanism changes regulating mechanism is crossed, to realize that suturing mechanism enters and the change of work angle controls, with suitable
The variation of wound suture angle, the control line 8 in 7 wall of deformed casing, one end is answered to connect 7 front end of deformed casing, the other end passes through
Deformed casing 7 is connected with positioning pipe 4, when sliding the sliding in sliding slot 2 of positioning device 3, control line 8 is pulled to slide together, and
8 front end of control line be fixedly connected with 7 front end of deformed casing, then can change length of the control line 8 in deformed casing 7, and the side
7 wall of deformed casing can be compressed, deformed casing 7 will bend at this time, and the control line 8 being pulled is equivalent in camber line
A piece straight line, other 8 length of control line also accordingly change, so the initial length of control line 8 and sliding positioning device 3 are in sliding slot
Position in 2 should all reserve appropriate surplus.Sliding positioning device 3 is pressed to the axle center of control handle and is slided, to adjust position
It sets, when pressing, positioning push plate 5 compresses compression spring 6 and loses to be hindered with the mantle friction of 2 upper lateral part of sliding slot, in people
It is freely slidable under control, it pulls corresponding control line 8 to move, behind position and good angular adjustment, unclamps the pressure of hand, compression spring
6 restore to the original state, and upward positioning push plate 5, positioning push plate 5 hinders the freedom of sliding positioning device 3 with the friction on 2 top of sliding slot
Displacement is realized and is positioned after adjusting.In the present embodiment, uses four control lines 8 and is arranged in the wall of deformed casing 7, you can
The shape adjustment of four angles of control, two control line 8 whiles is facilitated to adjust, moreover it is possible to realize with more angle changes, in wall
The interior confusion that can reduce control line 8, when device it is more preferably regular, reduce other interference, control line 8 can be also set to deformation set
The rational position on surface in or beyond pipe 7.
After work angle and position are set, sewing work is carried out to internal wounds, suturing mechanism, which uses, is similar to staple
Principle suture connection carried out to wound, the front end of working column 10 is directed at the wound that need to be sutured, 11 work of control microwave heating ring
Make, individual microwave heating is carried out to reach different temperature, without influencing whether to the memorial alloy 17 in stitching devices 15
Other internal organs, while filling with insulation material in collagen shell 16, heat-barrier material can be that receive heat-insulated soft felt of base etc. soft
Thermal coefficient it is low can be used for clinical medical material, slow down heat outside transmission and diffusion, collagen shell 16 plays guarantor
Shield acts on, and reduces or eliminates rejection of the human body to stitching devices 15.At different temperature, difference is presented in memorial alloy 17
Shape need the state of two shapes of memorial alloy 17, i.e. closed state and openning shape in suture and disassembly process
State makes the port of memorial alloy 17 be closed at one temperature, carries out grafting suture to wound and is kept for a period of time, another
At one temperature, memorial alloy 17 is made to open port, it is easy to disassemble.The existence time of collagen shell 16 should be greater than week of taking out stitches
Phase.Stitching devices 15 between two limiting slots 14, by the transverse shear stress of accessory plate 19 at port, increase outermost end in column
The friction of stitching devices 15 and limiting slot 14 avoids directly being extruded, and accessory plate 19 and axis are in an angle, in being convenient to
The stitching devices 15 in face add to outermost end, if by the vertical extruding of a holddown spring 18, when the stitching devices of outermost end
15 due to deformation the limitation of unrestricted position slot 14 and when being detached from, before the latter stitching devices 15 do not supplement up, compress bullet
Spring 18 is the outlet that can be blocked between limiting slot 14, influences the continuous operation of suture.
The both sides of wound are apart from each other be not easy to directly to rely on stitching devices 15 to carry out suture connection when, it is auxiliary by suturing
Help device that wound both sides are sutured connection again after.Two suction discs 21 touch the both sides of wound, and booster air pump 29 is evacuated, suction disc
21 be cavity structure, and surface is provided with equally distributed through-hole 22, and air pump 29 makes to generate negative pressure, surface and wound in suction disc 21
Both sides fitting, make suction disc 21 that the both sides of wound be sucked at this time, starter and the absorption of suction disc 21 act on simultaneously, in cylinder 26
Gas be extracted simultaneously, push rod 27 decline, while drive two suction discs 21 it is adjacent to each other, that is, drive wound both sides mutually lean on
Closely, in order to which the suture of stitching devices 15 connects.In the present embodiment, gas-guide tube 28 is in working column 10, deformed casing 7, operation
1 inside of handle is passed through to be connect with external air pump 29, reduces pipeline.
