Background
With the development and continued maturation of laparoscopic technology, diagnostic and therapeutic laparoscopes are being used extensively in the surgical field. The types of surgical complications are increased more than ever due to the enlargement of the surgical field and the increase of the surgical difficulty. The surgical complications which are less frequent in the past laparoscopic surgery, namely Hernia at the puncture Site (TSH), are also increased gradually, and the safety problem of laparoscopic therapy is attracting attention.
At present, a fascia closer is generally used for suturing an incision in laparoscopic surgery, and a Chinese patent of a laparoscopic thread knot pushing and suturing device (publication No. CN 104434238B) discloses a fascia closer structure, which comprises a guide and a suturing probe, wherein the guide comprises a fixed sleeve, a pull rod and movable wing plates, the guide is inserted into a puncture hole when in use, the two movable wing plates are in a closed state, the pull rod is operated to open the two movable wing plates and to be positioned below the cortex of the incision, and then the suturing probe is penetrated for suturing.
When the existing fascia closer is used, the penetration position of a suture probe is not easy to judge, and the injury is caused to human tissues. And the movable wing panel is easily broken due to the operation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a wicresoft's manadesma closer, this closer can play spacing and guide effect to sewing up the probe when using to reduce the tissue damage, strengthen the stability of apparatus simultaneously.
The utility model provides a technical scheme that its technical problem adopted is:
the minimally invasive fascia closer comprises an introducer and a suture probe, wherein the introducer comprises a sleeve, a pull rod and two movable wing plates, the two movable wing plates can be opened or closed along with the lifting of the pull rod, the sleeve is provided with a guide hole, and the pull rod and the sleeve are locked through a locking pin; the bottoms of the two movable wing plates are respectively connected with an arc-shaped supporting wing plate, and when the movable wing plates are closed, the movable wing plates and the supporting wing plates stretch straight along the pull rod; when the movable wing plate is opened, the supporting wing plate is outwards propped out, so that the movable wing plate and the supporting wing plate form a triangular wing; the suture probe passes through the movable wing plate and then forms fit with the supporting wing plate.
Furthermore, the pull rod body is provided with an inclined positioning hole, and when the movable wing plate and the supporting wing plate are integrally formed into a triangular wing, the positioning hole is correspondingly matched with the guide hole.
Furthermore, an annular groove is formed in the periphery of the upper portion of the pull rod, a return spring is arranged in the annular groove, and the return spring enables the pull rod to reset after the locking pin is loosened.
Furthermore, the pull rod head is provided with a cylindrical operating handle, the operating handle is provided with a holding and pinching groove used for being matched with fingers, and anti-skidding threads are further arranged on the periphery of the operating handle.
Further, the outer diameter of the introducer is 10.2mm, and the introducer can be matched with a puncture outfit with the inner diameter of 10.8mm for use.
Further, the outer diameter of the suture probe is 1.25mm, and the inclination angle of the needle head of the suture probe is 16 degrees.
The utility model has the advantages that:
when the movable wing plate and the supporting wing plate are used, the movable wing plate and the supporting wing plate form a triangular wing integrally, and after the suture probe penetrates through the movable wing plate, the supporting wing plate blocks and limits the suture probe, so that the accuracy of instrument operation is improved; and can enhance the stability of the instrument.
And secondly, only when the triangular wings are completely unfolded, the positioning holes can correspond to the guide holes, so that the suture probe can be smoothly inserted, otherwise, the suture probe cannot be inserted, and misoperation is prevented.
When the triangular wing locking device is used, after the pull rod is lifted and locked, the return spring is compressed, and after the locking pin is loosened, the return spring is used for returning the pull rod, so that the stroke action of the triangular wing is changed, and the jumping of the triangular wing locking device in the use process is prevented.
And fourthly, a pull ring on the traditional introducer is changed into an operating handle with a holding and pinching groove, and the outer diameter of the whole introducer is adjusted to be 10.2mm, so that the introducer can be used in cooperation with the puncture outfit, and secondary friction between tissues and instruments is prevented.
And fifthly, changing the outer diameter of the suture probe and the inclination angle of the needle head to reduce the damage to the human tissue.
