Detailed Description
The following detailed description of the staple pushing and suturing structure for an endoscopic puncture suturing device will be provided with reference to the accompanying drawings, which are provided for illustration and are not intended to limit the scope of the invention. The invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings.
Example 1
As shown in fig. 1 to 4, the staple pushing and suturing structure for a laparoscopic puncture stapler of example 1 includes a staple pushing rod 10, staples 20, a puncture cone 30, a return spring 40, a guide block 50, and a connecting portion 60. The nail pushing rod 10 is of a U-shaped metal structure, two ends of the U-shaped metal structure are bent, and the end of the bent shape is a needle point 11. As shown in FIG. 4, the staple 20 has curved surfaces 21 on both sides facing the abdominal cavity, and the smooth curved surfaces 21 reduce the probability of adhesions. The staple 20 has dovetail slots 22 and flats at the bottom to engage the cannula, the arrangement of the dovetail slots 22 not only facilitating the engagement of the cannula in the initial position, but also the design to engage the abdominal wall during use. The front end of the suturing nail 20 is of a conical surface structure, the taper of the conical surface structure is 15-30 degrees, and the conical structure is designed to be in transition fit with the nail pushing rod 10 to puncture the abdominal wall. The suturing nail 20 has a small volume, designed to be 10mm3～40mm3The implantation amount is small during operation, and the probability of adhesion is reduced. The suturing nail 20 is internally provided withA central through hole 23 is arranged for accommodating the nail pushing rod 10 to pass through, a front end outlet 26 of the central through hole 23 is positioned at the front end of the stitching nail 20, and the aperture of the front end outlet 26 is larger than the tip diameter of the needle point 11. The staple 20 has circular holes 24 on both sides for attachment of a suture. The puncture cone 30 is fixed to the connecting part 60, the guide block 50 is wound around the outer wall of the connecting part 60, and both ends of the U-shaped metal structure are engaged with the inclined surfaces of the guide block 50. And the return spring 40 is arranged between the nail pushing rod 10 and the connecting part 60. FIG. 1 shows the staple pusher suture assembly in a starting position where the curved shape of the ends of the U-shaped metal structure engage the angled surfaces of the guide block 50 and the needle tip 11 passes through the central through hole 23 in the staple 20 and exposes the front outlet 26. in the starting position, the staple 20 is positioned in the housing (piercing tube) of the stapler and the dovetails 22 of the staple 20 engage the inner walls of the housing. In this embodiment, the puncture awl 30 includes a connection arm 31 and a puncture awl body 32, the connection arm 31 is fixedly connected to the connection portion 60 by a fastener, in this embodiment, the guide block 50 and the connection portion 60 may be designed as separate components or as an integral structure, and the invention is not limited in particular. In the initial position, the staple 20 is at a distance H from the connecting arm 31 of the puncture cone 301，H1Less than 5 mm. As shown in FIG. 2, when the staple is pushed out through the fascia, the distance between the tip of the staple and the attachment arm is H2，H2The design is 5-15mm, which can ensure effective suture of incision. The nail pushing and suturing structure of the embodiment is mainly realized by means of the bending design of the nail pushing rod and the inclined plane of the guide block, when the nail pushing rod is pushed forwards, the nail pushing rod is propped open by the guide block, and when fascia is broken through, the needle point is 5-15mm away from the incision edge, namely, the suturing nail position is 5-15mm away from the incision edge. In this embodiment, the needle point of pushing away nail stick 10 is the metal material, compares in plastics needle point sharper, passes behind the peritoneum, sew up the nail and stay in the abdominal cavity, and the needle point withdraws from under return spring's cooperation, has avoided the risk that sharp position of sewing up the nail harms the tissue. To facilitate the penetration of the front end of the nail pushing rodCross sew up nail 20, central through-hole 23 is the bell mouth structure by rear end entry to front end exit design, the rear end aperture of bell mouth structure is greater than the front end aperture hole structure of bell mouth structure, the rear end aperture of bell mouth structure is greater than the front end aperture of bell mouth structure, so the design is also convenient for the nail pushing rod to withdraw from sew up nail 20.
The material of the suturing nail and the material degradation time of the suturing nail meet requirements of fascia healing time of 14 days and the requirement that the suturing nail is degraded in priority to the suturing nail, firstly, the connection strength of the suturing nail and the suturing nail can meet the requirement that more than 16N (abdominal wall tension) can be maintained within 14 days, and secondly, the risk that the suturing nail falls into an abdominal cavity due to degradation of the suturing nail in priority to degradation of the suturing nail can be avoided. The suturing nail material is PGA, PLGA5050 or PGLA, and the suturing thread material is PDO or PGCL.
The staple pushing suturing structure of the present embodiment is assembled into a piercing stapler as shown in FIG. 5. Before the puncture stitching instrument is used, the puncture cone and the sleeve are matched and assembled, and the taper of the central through hole of the stitching nail plays a role in guiding the nail pushing rod to penetrate into the stitching nail. When the suturing nail is in operation, the nail pushing handle is pushed, the nail pushing rod is forwards unfolded and pushed under the action of the guide block, when the suturing nail is pushed to the fascia position, the needle point is 5-15mm away from the edge of an incision, when the suturing nail completely enters the abdominal cavity, the nail pushing rod rebounds under the action of the handle and the spring, the tail of the suturing nail is larger than the size of the nail pushing rod, the suturing nail slips from the nail pushing rod, the suturing nail is pulled and attached to the abdominal wall under the action of the suturing thread, at the moment, the plane part of the dovetail groove of the suturing nail is attached to the abdominal wall, the arc-shaped surface deviates from the abdominal wall, the suturing nail is conveniently and correctly placed, the wire outlet part is in a plane, the nail pushing rod is avoided, and the suturing thread is wound from the outer side of the central hole.
It is obvious to those skilled in the art that the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the specific implementation of the present invention is not limited by the above-mentioned manner, and various insubstantial modifications made by the method concept and technical scheme of the present invention are within the protection scope of the present invention.
