Embodiment 1

[0023] like Figure 1-3 As shown, a puncture sheath with a suturing function includes a sheath body 1 and a peritoneal stapler. The peritoneal stapler includes a rod-shaped hollow stapler body 11 with a diameter of 5-12mm, and a push rod 12 arranged in the stapler body 11; the head of the stapler body 11 has a separable head valve 13. There are two head petals 13, and the back of the head petals 13 combined is arc-shaped or conical. The middle part of the head flap 13 is pivotally connected to the head of the suturing device body 11, and the tail end shares a pivot to be connected to the head of the push rod 12; the two side walls of the suturing device body 11 are provided with suture needle grooves 16 inclined downwards, The suture needle 14 is disposed within the suture slot 16 . The suture needle groove 16 is a stepped hole, the suture needle 14 tail has steps, and a return spring 17 is arranged between the suture needle 14 steps and the suture needle groove 16 steps. Th...

Embodiment 2

[0026] like figure 1 , 5 , 6, a puncture sheath with a suturing function, which includes a sheath body 1 and a peritoneal stapler. The peritoneal stapler includes a rod-shaped hollow stapler body 21 with a diameter of 5-12 mm, and a push rod arranged in the stapler body 21 . The head of the stapler body 21 has a detachable head flap 24. There are two head petals 24, and the head is arc-shaped or conical after the head petals 24 are combined; connect. The push rod includes a push rod sleeve 22 and a push rod core 23, and the push rod core 23 is inserted in the push rod sleeve 22; the head of the push rod core 23 is pivotally connected with the head valve 24. A return spring 29 is arranged between the upper surface of the tail and the top of the inner cavity of the push rod sleeve 22 . There is an upward arc-shaped suture needle groove 26 inside the head valve 24, and a suture needle 25 matching the radian of the suture needle groove 26 is arranged in the suture needle gro...

Abstract

The invention discloses a puncture sheath with a suturing function. The puncture sheath is characterized by comprising a sheath body and a peritoneal stapler which is inserted into the sheath body. A rod-shaped stapler body of the peritoneal stapler is inserted into a laparoscopic surgical wound through the puncture sheath; a suturing needle on the stapler body or a head flap passes through the peritoneum; a suturing thread head is left on the head flap or the stapler body; the thread head is pulled out when the stapler body is pulled out; the wound suturing is achieved. The stretched head flap is capable of positioning the abdominal wall organism tissues and avoiding the suture missing, and avoiding damaging other organs and tissues due to the suturing. The puncture sheath has the advantages of being simple to operate, good in suturing effect, effectively preventing the secondary injury when the wound is sutured, and reducing the incidence of incisional hernia.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, in particular to a puncture sheath with a suturing function. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive surgical method, which makes many open operations in the past have been replaced by endovascular surgery, greatly increasing the surgical options. With the development of laparoscopic technology, laparoscopic surgery has been accepted by more and more doctors and patients. Laparoscopic surgery must establish a working channel on the abdominal wall through a puncture sheath (trocar), and then use special lengthened surgical instruments to complete the same steps as open surgery under TV monitoring to achieve the same surgical effect. At present, the diameter of the puncture sheath is 5mm-12mm. Generally, the peritoneum and fascia must be sutured to prevent incision bleeding and reduce the incidence of incisional hernia when poking hol...
