Description
Technical Field
The invention belongs to the field of medical instruments, and is used for suturing and closing sleeve holes in laparoscopic surgery.
Background
The laparoscope technology is widely applied to various surgical operations, is popular among doctors and patients, has delicate operation, small wound, small abdominal wall incision and quick recovery of post-operation physiology and psychology, and is the development trend of minimally invasive surgery.
In laparoscopic surgery, 3-5 small incisions of 0.5-1.2 cm are often needed to be made on the abdomen of a patient, a cannula is arranged, and the surgical operation is carried out through a cannula hole; one of the sleeves is used to place a laparoscope, typically located in the umbilicus; after the operation is completed, the incision of the umbilical sleeve hole cannot be automatically retracted due to no abdominal muscle covering, and the suture is necessary. The curved needle is generally used for direct suturing clinically, but for the suture with small diameter and deep position of the sleeve hole from the base part, certain technical difficulty is caused in operation, and particularly for patients with obesity, the suture is difficult to be sutured to the bottom of the sleeve hole. Therefore, some patients may develop postoperative hernia of the cannula hole clinically. The designed cannula hole suturing device is inserted into a cannula hole by utilizing the appearance similar to that of a cannula when the operation is finished, the lower section of the suturing device is unfolded with the bracket part by pulling the operating rod, and the plane of the upper end of the bracket can be tightly attached to and firmly grasp the peritoneum beside the hole; rotating a knob at the top end of the suturing device to screw out a round needle in the middle of the suturing device, wherein the round needle penetrates through abdominal wall tissues beside the hole and penetrates through a glue film of the bracket through peritoneum; at the moment, the top knob is rotated reversely, so that the round needle returns back into the suturing device body along the way, and the suture thread brought out by the needle point is firmly clamped and hung on the adhesive film of the bracket; when the bracket is folded, the suturing device is taken out from the sleeve hole, and the sutures passing through the abdominal wall base part at the two sides are also pulled out together; and (4) tightening the suture and stably knotting to complete the sewing of the sleeve hole from the deep base.
Disclosure of Invention
The sleeve hole suturing device consists of three parts:
first, the housing part: "lower round, middle square, upper gate" (see attached figure 1 in the description)
Lower circle part: the lower end is a hemisphere with the diameter of 1.2cm, which is convenient for being placed in the abdominal wall casing hole.
The middle part: the side length of the square columnar body is 1.2cm, the volume occupying the sleeve hole is increased, the square columnar body is enabled to be tightly attached to the wall of the sleeve hole, meanwhile, the space in the middle of the suturing device is increased, and the support frame and the rotary suturing device are favorably arranged.
The upper organ part: 1. wing rods on both sides of the top end: when the wing rods on the two sides face upwards, the support frames on the two sides are contracted in the shell through the linkage rods, so that the support frames can be conveniently inserted into the sleeve holes; when the wing rods at the two sides are pulled downwards, the support frames at the two sides can be unfolded outwards to form a plane frame with 90 degrees, the plane frame is attached with a glue film, and the two sides of the frame are provided with the glue films with inward sawteeth. The suturing device is lifted upwards, and the two sides of the suturing device are tightly attached to the peritoneum beside the sleeve hole like a drag hook.
2. A top knob: the knob is arranged at the top of the screw rod, and when the knob rotates leftwards, the screw rod can drive the gears at the two sides to rotate, so that the circular needle fixed on the gear is screwed out of the shell, penetrates through abdominal wall tissues and pierces through a glue film at the horizontal part of the support frame; when rotated to the right, the double-sided circular needle may be rotated back into the housing.
Two, movable support frame part
The middle shell of the seaming device is internally provided with a support frame (please refer to attached figure 1 in the specification), a wing rod at the top end of the seaming device is pulled downwards, the support frame extends out of the shell and is supported to form a triangle, and the horizontal part of the support frame is right-angled with the shell. The surface of the horizontal part frame is attached with a glue film, and the two sides of the frame are provided with the glue films with inward sawteeth, so that the glue films are easy to attach and cling to the peritoneum. When the circular needle penetrates the adhesive film and retreats, the elastic force of the adhesive film can firmly clamp the suture line penetrated by the needle. The triangle formed by the support frame also has the function of isolation and protection, so as to prevent the round needle from hurting other tissues in the abdominal cavity. When the wing rod is pulled upwards, the supporting frame can be recovered into the shell of the seaming device, and when the seaming device is pulled out, the threads clamped on the adhesive film at the two sides are also taken out of the body.
Thirdly, rotating the circular needle part
The middle part of the suturing device is provided with a pair of circular suturing needles, the tail parts of the needles are symmetrically fixed on a pair of gears respectively (refer to the attached figures 2 and 3 of the specification), and the circular suturing needles are designed to rotate 120 degrees to be screwed out of the shell part to pierce the horizontal rubber membrane part of the support frame. Namely: when the knob at the top of the suturing device is rotated leftwards, the screw can drive the gears at the two sides to rotate, so that the circular needle is screwed out, penetrates through abdominal wall tissues and pierces through a glue film at the horizontal part of the support frame; when rotated to the right, the double-sided circular needle can be rotated back into the stapler housing. The other characteristics of the rotary circular needle are as follows: the needle tip section is designed with a notch which faces the needle tip direction. When the thread is hung at the notch of the needle point, the thread moves along with the needle when the needle is inserted, and the thread is separated from the needle when the needle is withdrawn. Two small barbs are arranged at the head end of the thread, and the thread moves along with the needle when the needle is inserted; the thread is separated from the needle when the needle is withdrawn, and the agnail of the thread can hook the glue film.
The invention has the beneficial effects that: compared with the prior art, the invention comprises a sewing needle, a shell and a movable support frame; operating wing rods to drive the supporting frame to open towards the two sides of the shell; the sawtooth on the surface of the support frame bites the part to be sutured; and the part to be sutured is closed to the shell; firstly, rotating a screw rod in the forward direction, driving a sewing needle to be screwed out of a shell by the screw rod, penetrating abdominal wall tissues to be sewn and puncturing an adhesive film; then the screw rod is rotated reversely, the sewing needle is driven to leave the adhesive film and return to the shell; the barb line is hung on the adhesive film and is taken out of the body along with the adhesive film; finally, the barbed lines which penetrate through the parts to be sewn on the left side and the right side are connected and sewn after the barbed lines are connected; the whole sewing process is rapid and convenient, and the barb thread penetrates out from the bottom of the part to be sewn, so that the problems of difficult sewing and incomplete sewing in the conventional sewing process are solved.
