Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an implantation assembly, a stitching instrument and a stitching method.
Background
When treating a tissue tear, the surgeon may choose to suture the tear with a stapler. The stapler includes a piercing needle, a firing mechanism, and a plurality of implants connected by sutures. The doctor firstly punctures the tissue on one side of the split by using the puncture needle, then uses the firing mechanism to fire one implant to the rear side of the tissue, withdraws the puncture needle, punctures the tissue on the other side of the split, fires the other implant to the rear side of the tissue, and can tighten the split by tightening the suture after multiple punctures and firings of the implants.
There are two main types of existing implants, one is a non-metallic implant made of a non-flexible material (e.g., PEEK material) that is engaged by the tissue posterior wall by its particular shape and is held against the tissue posterior wall. However, the material of such implants is relatively stiff, and the more the implant rubs against the tissue posterior wall the more damage it does as the implant spends longer in the body. The other type is a flexible implant, such as a cylindrical implant woven by a suture, because the implant is soft, the damage to the tissue back wall is small, but the contact area with the tissue back wall is the circular outer surface of the cylinder due to the limitation of the diameter size of the cylinder, the contact area is small, and if the implant moves for a long time, the implant enters into a tissue pore generated by puncture and moves from the tissue back side to the front side, so that the anchoring is not firm, and meanwhile, the risk of pull-back tearing is caused to the punctured tissue pore again.
Disclosure of Invention

Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The implant assembly provided by the embodiment of the invention can be used for suturing cracks of tissues such as meniscus and the like.
As shown in fig. 1-3, the implant assembly comprises: the suture 02 and the flexible object sheets 01, the number of the flexible object sheets 01 on the suture can be one, two or more, and the flexible object sheets are divided according to the type of the wound to be sutured. The flexible object piece 01 can be woven through a line body according to a textile processing technology, the line body used for weaving meets requirements of biocompatibility and the like, and the flexible object piece 01 is suitable for the medical field, and the woven flexible object piece 01 is also suitable for the medical field, and is particularly suitable for stitching menisci. Since the knitted fabric is formed by knitting a linear body, it has a certain flexibility and can be curled in the longitudinal direction and the width direction. And the density of the thread body when weaving is controlled, the compactness of the flexible object sheet 01 can be ensured, and the flexible object sheet 01 has good toughness. Among them, the suture 02 is a suture 02 suitable for the medical field, and is applicable to suture of meniscus.
The surface of the flexible object sheet 01 can be rectangular, the thickness dimension of the flexible object sheet 01 is far smaller than the width and length dimensions, the width dimension is between the thickness dimension and the length dimension, and the length dimension is larger than the width dimension. The length direction of the opened flexible object sheet 01 and the tearing direction of the tearing opening can be the same, namely, the extending direction of the oppositely-penetrated suture 02 on the flexible object sheet 01 and the tearing direction of the tearing opening can be the same, and the suture can cover tissues on two sides of the tearing opening to a greater degree, so that all positions of the tearing opening are tightly closed.
A plurality of flexible pieces 01 may be sequentially inserted through the suture 02 at intervals. The thread 02 is used for penetrating two surfaces of the flexible object sheet 01 in the thickness direction of the flexible object sheet 01 for multiple times, and a penetrating path of the thread 02 on each flexible object sheet 01 is arranged along a first direction. The number of times that the stitches 02 can be penetrated through the flexible object sheet 01 is not limited, and the stitches can be penetrated through the flexible object sheet for multiple times. Only the stitches 02 are ensured not to overlap the perforations, and the edges of the flexible object sheet 01 with the stitches 02 do not break.
The flexible object sheet 01 has an initial state in which the flexible object sheet 01 is curled in a second direction into a curled shape, wherein in the curled shape, the shape of the flexible object sheet 01 in the length direction and the thickness direction is unchanged, and the width direction is changed from an original rectangular shape to a curled shape. The flexible sheet 01, in a rolled configuration, may be placed into a stapler to facilitate implantation and passage through a puncture in tissue. After the flexible sheet 01 is conveyed to the tissue posterior wall, the flexible sheet 01 may be stretched or not stretched after being bound, that is, the stretched shape is restored to a rectangular shape before being stretched. The flexible object piece 01 can be abutted against the back wall of the tissue by tightening the suture 02, and if the flexible object piece 01 is not completely opened at the moment, the flexible object piece 01 is tightened and retracted in the first direction, and two side edges of the flexible object piece 01 in the second direction can be driven to be gradually opened. And after the tensioning is continued, the expanded flexible sheet 01 is tightened and formed in the first direction to be hung on the tissue back wall.
As shown in fig. 4-7, when suturing the laceration by using the above-mentioned implantation assembly, a first puncture site is selected at one side of the laceration of the tissue, and after a first flexible piece 01 with a curled shape on the suture 02 is implanted into the back wall of the tissue by using the suturing device, the first flexible piece 01 is completely opened or not completely opened. After the first flexible piece 01 is implanted, the suturing instrument is withdrawn from the first puncture site, a second puncture site is selected on the other side of the tissue tearing opening, and the suturing instrument is used for implanting the second flexible piece 01 with a curled shape into the back wall of the tissue. When two flexible object sheets 01 are placed on the rear side of the rear wall of the tissue, the suture 02 is tensioned, after the suture 02 penetrating the flexible object sheets 01 is tightened, the flexible object sheets 01 are tightened in the first direction, the flexible object sheets 01 which are not completely opened can be uncoiled in the second direction and gradually opened, after the suture 02 is tensioned continuously, the flexible object sheets 01 can be tensioned and contracted to be formed in the first direction and tightly hung on the rear wall of the tissue, and the flexible object sheets 01 are ensured not to enter into the puncture hole of the tissue due to the increase of the tension through the size of the flexible object sheets 01 in the second direction and the strength of the flexible object sheets 01 after contraction, so that the opening of the crack is ensured to be closed.
The flexible object sheet 01 may have other regular or irregular shapes besides the rectangular shape.
The threading path of the suture 02 on the flexible object piece 01 may be arranged along the symmetry axis of the flexible object piece 01.
That is to say, in the flexible object piece 01 in the curled shape, the suture 02 is located at the middle position, the flexible object piece 01 parts at the two sides of the suture 02 are in bilateral symmetry, and after the suture 02 is tensioned, the same tightening effect can be generated on the flexible object piece 01 parts at the two sides, so that the flexible object piece 01 after being contracted still abuts against the puncture hole in a symmetrical mode, and uniform pressure is generated on tissues.
For one of the flexible object pieces 01, the stitches 02 can be penetrated through the flexible object piece 01 for 2n times, n is an integer greater than or equal to 1, the stitches 02 can penetrate through the flexible object piece 01 for the first time from the first side to the second side and penetrate through the flexible object piece 01 for the last time from the second side to the first side, and the penetrating and penetrating ends of the stitches 02 are located on the same side of the flexible object piece 01. The flexible object piece 01 is curled in the direction that the second surface faces the first surface to form an initial state, so that the parts of the stitches 02 led out from the front end and the rear end of the flexible object piece 01 are all positioned outside the curled shape of the flexible object piece 01, and the expanded flexible object piece 01 is prevented from interfering with the stitches 02 when the stitches 02 are tightened. For example, in this embodiment, the number of opposite-threading operations may be four, the thread 02 may first pass through the flexible object sheet 01 from the first surface to the second surface, then pass through the flexible object sheet 01 from the second surface to the first surface, then pass through the flexible object sheet 01 from the first surface to the second surface, and finally pass through the flexible object sheet 01 from the second surface to the first surface, after the threading is completed, the flexible object sheet 01 is curled in a direction in which the second surface faces the first surface to form an initial state, so that both ends of the thread 02 connected to the flexible object sheet 01 are located outside the curled shape.
The suture 02 comprises a branching part, the branching part comprises at least two branching units, the branching units comprise first ends and second ends, the first ends of the at least two branching units are connected, and the second ends of the at least two branching units are connected; at least two branching units penetrate through two surfaces of the flexible object sheet 01 in the thickness direction of the same flexible object sheet 01 for multiple times.
In another embodiment, as shown in fig. 9, at least two line-dividing units are arranged on the flexible object sheet 01. Specifically, in the length direction of the suture 02, the suture 02 is provided with a suture part, first ends of the same sides of the branching units in the branching parts are connected with each other, and second ends of the same sides of the branching units are connected with each other, that is, the line body of the suture 02 is divided into a plurality of independent branching units at the starting position of the branching part, the length of the branching units is greater than that of the flexible object piece 01 in the first direction, and the branching units and the flexible object piece 01 penetrate through each other and then are converged into one line body. The at least two branching units support the flexible object sheet more stably, the flexible object sheet 01 is not easy to incline, and the at least two branching units can fix the position of the suture 02 of the flexible object sheet 01 and only can be positioned in the branching parts without sliding on any position on the suture 02.
The flexible object piece 01 is in a flat tube shape, and the opening direction of the flexible object piece 01 is the second direction.
In yet another possible embodiment, as shown in fig. 10, flexible sheet 01 is no longer an open sheet structure, but is in the shape of a flat tube with ends joined end to end, i.e. closed in the first direction, the contact surface of closed flexible sheet 01 with the tissue back wall is a flat surface, and there is no contact of the end surface of flexible sheet 01 with the tissue, so closed flexible sheet 01 is softer and less traumatic to the tissue back wall than open flexible sheet 01. Similarly, as shown in fig. 11, the closed flexible sheet 01 may be connected by a two-way connection of at least two branching units.
The number of flexible pieces 01 threaded on the stitches 02 can be two, three, four or even more, depending on the case of different tears. In this embodiment, the number of the flexible pieces 01 is two, and the tear-off port is closed by anchoring one flexible piece 01 to each of both sides of the tear-off port.
The embodiment of the invention provides a stitching instrument which comprises the implant assembly. The tearing opening is sewn by the stitching instrument, so that the tearing opening can be closed more stably.
The suturing method provided by the embodiment of the invention comprises the following steps of:
s1, selecting a first puncture point on one side of the tissue tearing opening, and implanting a first flexible object sheet 01 in a curled shape into the rear wall of the tissue by using a stitching instrument.
A first puncture site on one side of the tear opening is defined through which a puncture needle of the stapler will pass leaving a small hole in the tissue. After passing through the tissue, the first flexible sheet 01 is implanted. In this case, the flexible material piece 01 is in a state before being stretched, i.e., the rolled shape in the width direction is restored to a rectangular shape before being rolled. As shown in fig. 4, the flexible object sheet 01 is hung on the tissue back wall in a mode of being vertical to the tissue back wall, wherein the suture 02 in the flexible object sheet 01 needs to be oriented towards the left side or the right side.
S2, withdrawing the suturing device from the first puncture point, selecting a second puncture point on the other side of the tissue tearing opening, and implanting a second flexible object sheet 01 in a curled shape into the back wall of the tissue by using the suturing device.
After implanting the first flexible article 01, the stapler is withdrawn, a second puncture site is defined on the other side of the tissue tear, and the tissue is punctured from the second puncture site to form a second aperture on the other side of the tissue tear. After the two flexible object sheets 01 are hung on the back wall of the tissue, the two flexible object sheets 01 can be inclined with each other, but the two flexible object sheets 01 are not contacted with each other. As shown in fig. 5, the stitches 02 of the second flexible object 01 are oriented to the left or to the right, and are in the same direction or in the opposite direction to the stitches 02 of the first flexible object 01.
Depending on the type of meniscal tear (direction of elongation of the tear) the two flexible panels 01 may be attached in a vertical or horizontal manner. As shown in fig. 8, if the flexible sheets 01 are horizontally arranged, the stitches 02 in the flexible sheets 01 need to be upward or downward, and the corresponding other flexible sheet 01 is in the same direction or opposite direction to the first flexible sheet 01, so that neither flexible sheet 01 can protrude out of the tissue back wall.
And S3, tightening the suture 02 to close the tearing opening.
Both flexible sheets 01 have been placed on the tissue posterior wall, but the flexible sheets 01 have not fully opened. The flexible piece 01 can be opened by tightening the suture 02. As shown in fig. 6, the shape in the width direction is gradually restored to its original shape.
Continued tightening of the sutures 02 closes the tissue tear, as shown in FIG. 7, which allows the flexible panel 01 to contract. By contraction, it is meant that the flexible sheet 01 contracts and bends along its length and tightly engages the tissue posterior wall. The size of the flexible object sheet 01 in the width direction and the strength of the flexible object sheet 01 after shrinkage are enhanced, so that the flexible object sheet 01 is ensured not to enter the tissue pore due to the increase of the tensile force. Meanwhile, the flexible object sheet 01 can be stably hung on the rear wall of the tissue through the two characteristics, and the tearing opening is ensured to be closed.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
