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
In treating tissue tears, the surgeon may choose to suture the tear using a stapler. The stapler includes a needle, a firing mechanism, and a plurality of implants connected by a suture. The doctor uses the puncture needle to puncture the tissue at one side of the split, then uses the firing mechanism to fire one implant to the rear side of the tissue, withdraws the puncture needle, punctures the tissue at the other side of the split, fires the other implant to the rear side of the tissue, and after multiple punctures and the firing of the implants, the split can be tightened by tightening the suture.
There are two main types of implants available, a non-metallic implant made of a non-flexible material (such as PEEK material) that, by its particular shape, comes into contact with the tissue posterior wall, hanging against it. However, the material of such implants is harder, and the more the implant rubs against the tissue posterior wall, the more damaging the tissue posterior wall as the implant is in the body for longer periods of time. The other is a flexible implant, such as a cylindrical implant woven by suture, because the implant is softer, the damage to the rear wall of the tissue is small, but the contact area between the implant and the rear wall of the tissue is limited by the diameter size of the cylinder, namely the circular outer surface of the cylinder, the contact area is small, if the implant moves for a long time, the implant enters into a small hole of the tissue generated by puncture and moves from the rear side of the tissue to the front side, and the risk of pulling back and tearing the small hole of the punctured tissue again when the anchor is not firm is caused.

Detailed Description
The technical solutions of the present invention will be clearly and completely described in connection with the embodiments, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The implantation component provided by the embodiment of the invention can be used for suturing tissue cracks such as meniscus and the like.
As shown in fig. 1-3, the implant assembly includes: the number of the flexible object sheets 01 on the suture line can be one, two or more, and the suture line 02 and the flexible object sheets 01 are divided according to the type of wound to be sutured. The flexible object sheet 01 can be formed by weaving the wire body according to a weaving processing technology, the wire body used for weaving meets the requirements of biocompatibility and the like, the flexible object sheet 01 is suitable for the medical field, and the flexible object sheet 01 after weaving is also suitable for the medical field, in particular for the suture of meniscus. Since the yarn is woven from the yarn body, the yarn has a certain flexibility, and can be curled in the longitudinal direction and the width direction. And the density of the wire body during knitting is controlled, so that 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 medical field, and can be used for suture of meniscus.
The surface of the flexible sheet 01 may be rectangular, and the thickness dimension of the flexible sheet 01 is much smaller than the width and length dimensions, the width dimension being between the thickness dimension and the length dimension, and the length dimension being greater 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, that is, the extending direction of the opposite-penetrating suture line 02 on the flexible object sheet 01 and the tearing direction of the tearing opening can be the same, and the suture line can cover tissues at two sides of the tearing opening to a greater extent, so that each position of the tearing opening is tightly closed.
A plurality of flexible sheets 01 may be threaded onto the suture 02 at sequentially spaced intervals. The suture thread 02 is used for carrying out multiple times of threading on two sides of the flexible object sheet 01 in the thickness direction of the flexible object sheet 01, and the threading path of the suture thread 02 on each flexible object sheet 01 is arranged along the first direction. The number of times that the suture 02 can be used for putting on the flexible object sheet 01 is not limited, and the suture can be put on for many times. Only the perforation of the suture 02 is ensured not to be overlapped, and the edge of the flexible object sheet 01 which is perforated by the suture 02 is not damaged.
The flexible sheet 01 has an initial state in which the flexible sheet 01 is curled in a second direction to a curled shape, wherein in the curled shape, the shape of the flexible sheet 01 in the length direction and the thickness direction is unchanged, and the width direction is changed from the original rectangular shape to the curled shape. The flexible sheet 01 in the rolled shape can be placed into a stapler to facilitate implantation and passage through a puncture in tissue. After the flexible sheet 01 is delivered to the tissue back wall, the flexible sheet 01 may or may not be stretched after being bound, i.e., the curled shape in the width direction returns to the rectangular shape before curling. The tensioning suture 02 can be used for abutting the flexible object sheet 01 on the tissue rear wall, and if the flexible object sheet 01 is not fully opened at the moment, the flexible object sheet 01 is tightened and retracted in the first direction, and two side edges of the flexible object sheet 01 in the second direction can be driven to be gradually opened. After the tension is continued, the opened flexible object sheet 01 is tightened and formed in the first direction and is hung on the rear wall of the tissue.
As shown in fig. 4-7, when the above-mentioned implantation assembly is used to suture the tear, a first puncture point may be selected on one side of the tissue tear, and after the suture 02 is implanted into the tissue back wall by using the suture device, the first flexible sheet 01 is fully or not fully opened. After the first flexible object sheet 01 is implanted, the stitching instrument is withdrawn from the first puncture point, a second puncture point is selected at the other side of the tissue tearing opening, and the stitching instrument is used for implanting the second flexible object sheet 01 with a curled shape into the rear wall of the tissue. When two flexible object pieces 01 are placed on the rear side of the tissue rear wall, the tensioning operation of the suture 02 is carried out, after the suture 02 penetrating through the flexible object pieces 01 is tightened, the flexible object pieces 01 are tightened in the first direction, the incompletely opened flexible object pieces 01 can be uncoiled in the second direction and gradually opened, after the suture 02 is continuously tensioned, the flexible object pieces 01 can be tensioned, contracted and formed in the first direction and tightly hung on the tissue rear wall, and the size of the flexible object pieces 01 in the second direction and the strength of the contracted flexible object pieces 01 are enhanced to ensure that the flexible object pieces 01 cannot enter a puncture hole of the tissue due to the increase of tensile force, so that the crack opening is closed.
The flexible sheet 01 may have a rectangular shape, but may have other regular or irregular shapes.
The threading path of the suture thread 02 on the flexible object sheet 01 can be arranged along the symmetry axis of the flexible object sheet 01.
That is, in the flexible object sheet 01 having a curled shape, the suture thread 02 is located at the middle position, the flexible object sheet 01 portions at two sides of the suture thread 02 are bilaterally symmetrical, and after the suture thread 02 is tensioned, the same tightening effect can be generated on the flexible object sheet 01 portions at two sides, so that the contracted flexible object sheet 01 still abuts against the puncture hole in a symmetrical form, and uniform pressure is generated on tissues.
For one of the flexible object sheets 01, the suture 02 can be threaded for 2n times, n is an integer greater than or equal to 1, the suture 02 can be threaded through the flexible object sheet 01 for the first time from the first surface to the second surface, and threaded through the flexible object sheet 01 for the last time from the second surface to the first surface, and the penetrating and penetrating ends of the suture 02 are positioned on the same side of the flexible object sheet 01. The flexible object sheet 01 is curled in the direction of the second surface towards the first surface to form an initial state, so that the parts of the suture lines 02 led out from the front end and the rear end of the flexible object sheet 01 are all positioned on the outer sides of the curled shape of the flexible object sheet 01, and the unfolded flexible object sheet 01 and the suture lines 02 are prevented from interfering when the suture lines 02 are tightened. For example, in this embodiment, the number of times of threading may be four, the suture thread 02 may first pass through the flexible object sheet 01 from the first face to the second face, then pass through the flexible object sheet 01 from the second face to the first face, then pass through the flexible object sheet 01 from the first face to the second face, finally pass through the flexible object sheet 01 from the second face to the first face, and after threading is completed, the flexible object sheet 01 is curled with the second face to the first face to form an initial state, so that both ends of the suture thread 02 segment connected with 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 a first end and a second end, 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 are used for carrying out multiple times of wearing on the two sides of the flexible object sheet 01 in the thickness direction of the same flexible object sheet 01.
In another possible embodiment, as shown in fig. 9, at least two branching units are provided on the flexible sheet 01. Specifically, in the length direction of the suture thread 02, the suture thread 02 is provided with a suture thread part, the first ends of the same sides of the thread branching units in the thread branching part are connected with each other, the second ends of the same sides are connected with each other, that is, the thread body of the suture thread 02 is divided into a plurality of independent thread branching units at the beginning of the thread branching part, the length of the thread branching units is greater than that of the flexible object sheet 01 in the first direction, and the thread branching units are assembled into a thread body after being worn by the flexible object sheet 01. The flexible object sheet 01 is supported more stably by the at least two branching units, and is not easy to incline, and the at least two branching units can fix the position of the suture 02 where the flexible object sheet 01 is located, can only be located in the branching part, and cannot slide at any position on the suture 02.
The flexible object sheet 01 is in a flat tubular shape, and the opening direction of the flexible object sheet 01 is in a second direction.
In yet another possible embodiment, as shown in fig. 10, the flexible sheet 01 is no longer in an open sheet-like structure, but is in a flattened tubular shape by end-to-end connection, i.e. is closed in the first direction, the contact surface of the closed flexible sheet 01 with the tissue back wall is a flat surface, there is no contact of the end surface of the flexible sheet 01 with the tissue, and thus the closed flexible sheet 01 is softer and less damaging to the tissue back wall than the open flexible sheet 01. Similarly, as shown in fig. 11, the enclosed flexible object sheet 01 may be connected by at least two branching units in a putting-on mode.
The number of the flexible object sheets 01 to be worn on the suture 02 can be two, three, four or even more according to the situation of different tearing slits. In this embodiment, the number of the flexible sheets 01 is two, and the tear is closed by anchoring one flexible sheet 01 on each side of the tear.
The suture device provided by the embodiment of the invention comprises the implantation assembly. By using the stitching instrument to stitch the tearing opening, 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 at one side of a tissue tearing opening, and implanting a first flexible object sheet 01 in a curled shape into a tissue rear wall by using a stitching instrument.
A first puncture site is defined on one side of the tear seam through which a needle of the stapler passes leaving a small hole in the tissue. After penetrating the tissue, the first flexible sheet 01 is implanted. The flexible sheet 01 is in a state before being stretched, that is, the stretched state, that is, the curled shape in the width direction is restored to the rectangular shape before being curled. As shown in fig. 4, the flexible sheet 01 is hung on the tissue back wall in a form of being perpendicular to the tissue back wall, wherein the suture line 02 in the flexible sheet 01 is required to be oriented to the left or the right.
S2, withdrawing the stitching instrument from the first puncture point, selecting a second puncture point at the other side of the tissue tearing opening, and implanting a second flexible object sheet 01 with a curled shape into the rear wall of the tissue by using the stitching instrument.
After the first flexible object sheet 01 is implanted, the stitching instrument is retracted, a second puncture point on the other side of the tissue tearing opening is determined, the tissue is punctured from the second puncture point, and a second small hole is formed on the other side of the tissue tearing opening. After penetrating the tissue, the second flexible object sheet 01 is implanted, and 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 relative to each other, but the two flexible object sheets 01 are not contacted with each other. As shown in fig. 5, the suture 02 of the second flexible object 01 is required to be oriented leftwards or rightwards, and the suture 02 of the first flexible object 01 is oriented in the same direction or opposite direction.
Depending on the type of meniscus tear (direction of extension of the tear) two flexible sheets 01 can be hung up in a vertical or horizontal manner. As shown in fig. 8, if the flexible object sheets 01 are laid out horizontally, the suture lines 02 in the flexible object sheets 01 need to be upward or downward, and the other flexible object sheet 01 is the same as or opposite to the first flexible object sheet 01, and neither flexible object sheet 01 can emerge from the tissue back wall.
And S3, tensioning 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 are not fully expanded. The flexible sheet 01 can be opened by tightening the suture 02. As shown in fig. 6, the shape in the width direction gradually returns to the original shape.
Continued tightening of suture 02 closes the tissue tear, as shown in FIG. 7, allowing flexible sheet 01 to contract. The contraction means that the flexible sheet 01 is contracted and bent along the length direction and is tightly hung on the rear wall of the tissue. By the dimension of the flexible material sheet 01 in the width direction and the strength enhancement of the flexible material sheet 01 after shrinkage, it is ensured that the flexible material sheet 01 does not enter into the tissue aperture due to the increase of the pulling 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 closed.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
