Absorbable tissue closed fixing device

Abstract

The invention relates to an absorbable tissue closed fixing device, and belongs to the field of medical instruments. The device is made of a biological absorbable material, the device is composed of abase plate 1, a puncture needle 2 and a reverse spine 3, the puncture needle 2 is arranged on the base plate 1, the angle between the base plate 1 and the puncture needle 2 is 45 degrees to 90 degrees, the reverse spine is arranged on the puncture needle 2, and the angle between the reverse spine 3 and the sharp end direction of the puncture needle 2 is greater than or equal to 135 degrees. According to the device, the device is used for sewing up a skin soft tissue wound and potential lacuna and fixing soft tissues and bones during an operation. The device is simple to operate, the influenceof blood supplying on the marginal tissue of the wound is small, the healing time of the wound is short, and the device is made of the biological degradable / biological absorbable material, so that the device is capable of being gradually degraded in a human body and absorbed by the human body.

Description

technical field [0001] The invention relates to a surgical suturing instrument, in particular to an absorbable tissue closure fixer, which belongs to the field of medical instruments. Background technique [0002] Suture fixation of skin and soft tissue is one of the most commonly performed procedures in surgery. Whether it is direct vision surgery with large incisions or various endoscopic surgeries, the currently commonly used tissue suturing methods have their own disadvantages: ①. Although the direct vision surgery has a long incision, a large field of view, and easy suture operation, it is time-consuming and expensive. The remaining skin scar is long, which seriously affects the appearance and even affects the movement function of the joint; ②. In order to reduce the incision scar left in the skin and soft tissue as the surgical approach, it is necessary to make the skin and soft tissue incision as small as possible in the concealed part, but it will Increase the diffi...

Whether it is direct vision surgery with large incisions or various endoscopic surgeries, the currently commonly used tissue suturing methods have their own disadvantages: ①. Although the direct vision surgery has a long incision, a large field of view, and easy suture operation, it is time-consuming and expensive. The remaining skin scar is long, which seriously affects the appearance and even affects the movement function of the joint; ②. In order to reduce the incision scar left in the skin and soft tissue as the surgical approach, it is necessary to make the skin and soft tissue incision as small as possible in the concealed part, but it will Increase the difficulty of suturing deep tissues away from the incision, especially for obese patients, often need to extend the incision or make another incision at the deep tissue that needs to be sutured to facilitate exposure and suturing; ③, sneak cavity, endoscopic surgery The operation of suturing and knotting in small incisions such as subcutaneous soft tissue filling is also very complicated and inconvenient, and doctors need to practice for a long time before they can operate proficiently; ④. Lifting and fixing of skin and soft tissue in wrinkle removal surgery (must be sutured with periosteum) It is not strong enough and reliable, and the sutures are often torn off due to gravity, and the effect cannot last; ⑤, tendon reattachment after osteotomy (referring to: after the bone attached to the tendon is removed, the reattachment of the tendon to the retained bone) is extremely difficult, and it should be caused Weakened muscle tone and strength

CN103519857A (Patent No., the same below) discloses a three-dimensional structure of absorbable metal closing nails in the body and the disclosed tissue closing clips of CN204562278U can be completely absorbed by the human body, but the two nail legs of the closer nail (clip) U-shaped must be worn. The skin and soft tissue on both sides of the wound can be closed, and the tissue damage at the wound edge is large, which can easily affect the blood supply of the wound edge and affect wound healing

CN100556373C discloses a kind of laparoscopic surgery suturing staple, manufactures barb at one end or both ends of U-shaped nail, meanwhile U-shaped nail arm is pressed with anti-slip lines, the purpose is to prevent U-shaped nail from being damaged by the elastic recovery force of clamped tissue. Slipping occurs under action, but affected by the size of the U-shaped nail, the barb at the end, and the opening degree of the clamp head of the surgical suturing forceps, when suturing the skin, the tissues on both sides of the surgical incision must be pulled toward the incision, and the two ends of the incision must be closed. The incision can only be closed with surgical suturing forceps when the tissues are close to a certain degree, which is labor-intensive and inconvenient when suturing deeper tissues
