Problems solved by technology

It is disclosed that this patent mainly solves the problem that when the puncture rod is pulled out from the incision of the one-way valve, the incision is easy to roll up in the direction of pulling out (commonly known as "turning the skin")
However, there is no report about the puncture device that can solve the problem of expanding the scope of surgical operations and avoiding the congestion of extra-abdominal instruments while maintaining the stability of intra-abdominal pressure.

Embodiment 3

[0038] The usage method of the single-hole laparoscopic puncture device in Example 2 of the present invention:

[0039] After routine surgical treatment of the patient, insert a single-hole laparoscopic puncture device in Example 2 into the umbilicus, take out the inner core from the pressurized cap, insert the laparoscopic instrument, and carefully exit the single-hole laparoscopic puncture device, the surgeon applies force to both sides between the other end of the first semicircular outer casing body and the other end of the second semicircular outer casing body (such as Figure 4 ) Separate the two ports and remove the outer casing. After the outer sleeve is removed, the outer sleeve body automatically closes the first semicircular outer sleeve body and the second semicircular outer sleeve body under the action of the return torque of the torsion spring. When the surgical instrument is withdrawn, the operator applies force to both sides between the other end of the first ...

Abstract

The invention relates to a special puncture outfit for a single-pore peritoneoscope. The puncture outfit comprises a pressurizing cap, a sealing cap, a liner core and an outer sleeve, wherein the outer sleeve comprises an outer sleeve body and an outer sleeve inward-extending part; the outer sleeve body consists of a first semicircular outer sleeve body and a second semicircular outer sleeve body; one end of the first semicircular outer sleeve body is connected with one end of the second semicircular outer sleeve body through a torsion spring; and the outer sleeve inward-extending part consists of a first half-cone outer sleeve inward-extending part and a second half-cone outer sleeve inward-extending part. The outer sleeve body of the conventional peritoneoscope puncture outfit has an integrated sleeve-shaped structure, and the outer sleeve body of the puncture outfit of the single-pore peritoneoscope consists of the two semicircular outer sleeve bodies. The special puncture outfit for the single-pore peritoneoscope provides convenience for dismounting the outer sleeve, thereby enlarging the operation operating range, avoiding crowding of apparatus outside an abdominal cavity and providing convenience for operation under the condition that the intra-abdominal pressure is stable.

Description

【Technical field】 [0001] The invention relates to a trocar, in particular to a trocar dedicated to single-hole laparoscope. 【Background technique】 [0002] With the development of the application of minimally invasive techniques in the field of general surgery, on the premise of ensuring safety and achieving the same curative effect, it has become a consensus goal to adopt less invasive diagnosis and treatment methods. Since traditional laparoscopic surgery requires multi-point puncture on the body surface and the insertion of lighting systems and surgical instruments, multiple surgical scars will be left on the body surface. In order to further reduce trauma and reduce the occurrence of related complications, the Umbilical single port laparoscopic surgery (E-NOTES) came into being. In short, E-NOTES is to produce pneumoperitoneum through umbilical foramen, insert a puncture cannula with multiple operating channels, and introduce surgical instruments and lighting equipment ...
