A kind of puncture outfit of band suture function, it includes the suturing assembly of puncture outfit and insertion puncture cannula, and the suturing assembly includes outer tube, push rod；The head of the outer tube has the gear with crotch, and the head of the gear crotch has syringe needle；The side opening of the syringe needle has the suture of dimension；The push rod head has the rack gear with the gear cooperation with crotch；The rack gear cooperates with the gear with crotch can be achieved syringe needle arcuate rotation.The push rod pushes after crotch is opened to be closed up again, and syringe needle is inserted into the symmetrical holes on puncture outfit casing tube head after passing through suture site, then opens suturing assembly, and syringe needle is separated with crotch is retained in suture the end of a thread in puncture outfit side wall.Realize the fascia suture in operation.The present invention has the advantages that simple structure and reasonable design, the pain for shortening operating time, reducing patient, improves procedure efficiency, is safe and reliable.
Description
Technical field
The present invention relates to surgical operating instrument technical fields, more particularly to a kind of puncture outfit of band suture function.
Background technique
The appearance of Minimally Invasive Surgery and there are a more than ten years in the extensive use of medical domain, Minimally Invasive Surgery has wound
Superiority small, pain is light, recovery is fast.Many past open operations have been replaced by intracavity operation now, and Minimally Invasive Surgery obtains
Great development and exploitation are arrived, endoscope-assistant surgery is received by more and more doctors and patient.Laparoscopic surgery must lead to
It crosses puncture outfit and establishes service aisle on stomach wall, surgical instrument is implemented to perform the operation by service aisle to patient.Puncture outfit is advised at present
Lattice are diameter 5mm-18mm, generally for the stomach wall puncture for being greater than 5mm, it is necessary to which peritoneal suture and fascia layer are to prevent notch bleeding
And reduce the incidence of incisional hernia.Traditional sewing method can not make small notch two due to lacking necessary guidance positioning means
The tissue of side is corresponding, it is difficult to reach ideal sewing effect.It need to be carried out when being sutured using fascia stitching unstrument complex
Operation.The working efficiency for affecting medical personnel in this way, extends operating time, increases the pain of patient, this is asked
Topic must be accounted for.
Summary of the invention
The purpose of the present invention is can not suture Minimally Invasive Surgery wound for existing puncture outfit.Design a kind of band suture function
Puncture outfit.
The technical scheme is that
A kind of puncture outfit of band suture function, it is characterised in that: it includes the suturing assembly of puncture outfit and insertion puncture cannula, institute
Stating suturing assembly includes outer tube 1, push rod 2；The head of the outer tube 1 is equipped with gear 3, is equipped on gear 3 and rotates with gear
Crotch 4, the head of the crotch is equipped with syringe needle 5；The suture 6 of dimension is coated in the side opening of the syringe needle 5；It is described
The head of push rod 2 has the rack gear 7 cooperated with gear 3；The rack gear 7 realizes the arcuate rotation of syringe needle 5 with the cooperation of gear 3.
There is the protrusion 8 matched with card slot on puncture outfit in the tail end rotary table of the outer tube 1, outer tube 1 can be fixed on
On puncture outfit, so as not to rotate；The inside of 1 outer tube is equipped with through slot, and push rod 2 is equipped with the limit matched with the through slot
Structure 9 can be such that push rod 2 is fixed in outer tube 1 and will not push through critical distance.
There is the card slot to match with outer tube on the outer profile of the push rod.
The head end of the outer tube 1 is equipped with the cylinder of protrusion；Gear is mounted on the cylinder of the protrusion；The crotch
Concentric rotation can be carried out by rotating gear.
The puncture cannula head end of the puncture outfit has symmetrical holes；The symmetrical holes are the small structure of outer imperial palace, and syringe needle can be made suitable
Benefit insertion is difficult to extract.
Beneficial effects of the present invention:
The present invention compared with prior art compared with, have the advantage that design rationally, structure is simple, suture can be effectively prevented
When secondary damage, solve the defect that puncture outfit does not suture function.The work for shortening operating time, improving medical worker
Make efficiency, the pain for alleviating patient, improve surgical quality.
Detailed description of the invention
Fig. 1 is schematic diagram of the three-dimensional structure.
Fig. 2 is outer tube and push rod assembling structure schematic diagram of the invention.
Fig. 3 is the A-A cross-sectional view of Fig. 2.
Specific embodiment
As shown in Fig. 1-3.
A kind of puncture outfit of band suture function, it includes the suturing assembly of puncture outfit and insertion puncture cannula, the suture
Component includes outer tube 1, push rod 2；
The head of the outer tube 1 has the gear 3 with crotch 4, and the head of the crotch 4 has syringe needle 5；The side of the syringe needle 5
Hole has the suture 6 of dimension, as shown in Figure 1；2 head of push rod has the rack gear 7 cooperated with the gear 3 with crotch；
The rack gear 7 cooperates with the gear 3 with crotch can be achieved syringe needle arcuate rotation；The pushing of push rod 2 makes gear 3 drive syringe needle 5
Rotation；The syringe needle 5 is inserted into the symmetrical holes of puncture outfit casing tube after passing through suture site, and suture the end of a thread stays in puncture outfit side wall
It is interior.There is raised 8(such as Fig. 2 matched with card slot on puncture outfit, 3) in the tail end rotary table of the outer tube 1, outer tube 1 can be consolidated
It is scheduled on puncture outfit, so as not to rotate；The inside of the outer tube 1 is equipped with through slot, and push rod 2 is equipped with and matches with the through slot
Bulge-structure and position limiting structure 9 can be such that push rod 2 is fixed in outer tube 1 and will not push through critical distance.It can be outside when specific implementation
The head end of pipe 1 is equipped with the cylinder of protrusion；Gear 3 is mountable on the cylinder of the protrusion；Crotch 4 can be by rotation gear
The concentric rotation of row.
Operation is when needing to suture puncturing hole, by the casing of suturing assembly insertion puncture outfit, according to patient's medical conditions and
Art formula need to adjust puncture outfit insertion depth, fix puncture outfit casing push suturing assembly push rod, by rack gear with
The cooperation crotch of gear will carry out circular motion.Meanwhile the syringe needle of gear crotch front end passes through and suture site insertion is needed to puncture
In the symmetrical holes of device casing.Upward pulling-pushing rod, gear crotch reset, since the symmetrical pore structure of puncture outfit casing tube is that outer imperial palace is small,
Syringe needle cannot be exited smoothly from collar aperture, and syringe needle and crotch separation, crotch reset to original state, and syringe needle then stays in puncture outfit set
In tube cavity, while the hole passed through on syringe needle with suture, the end of a thread of suture just stay in puncture outfit casing tube together with syringe needle
In chamber.It extracts puncture outfit and suturing assembly, two the end of a thread of suture is just taken out of together, tighten suture and knotted just
The fascia suture of puncture incision in Minimally Invasive Surgery can be achieved.
