Pneumoperitoneum-free peritoneoscope suspending type abdominal wall puncture device

Abstract

A pneumoperitoneum-free peritoneoscope suspending type abdominal wall puncture device comprises a sleeve (1) and a plurality of supporting arms (3) arranged on the sleeve (1) in a central radial shape. A deformation portion (2) is connected to an end portion of the sleeve (1), and the supporting arms (3) are connected to the deformation portion (2). One end of each of pull ropes (4) is fixed on an end portion of the supporting arms (3), lugs (5) with rope holes (6) are arranged on the sleeve (1) away from the deformation portion (2), and the other end of each of the pull ropes (4) passes through the rope holes (6) in the lugs (5) and are fixed to the outer portion of the abdominal wall. A supporting surface is provided after the supporting arm (3) is opened, and a barrel-shaped space is formed after the supporting arm is suspended, so that enough surgical fields are provided during the surgery. The supporting arm (3) of the puncture device is inserted from a cut of the abdominal wall and is opened gradually, so that it does not need to perform puncture and suspension using the Kirschner pin, thereby avoiding the secondary trauma, and alleviating traumatic pains of patients.

Description

technical field [0001] The invention relates to a laparoscopic surgical instrument, in particular to a gas-free laparoscopic suspension abdominal wall puncture device which does not need to inflate the inside of the abdominal cavity and only relies on mechanical lifting to lift the tympanic cavity. Background technique [0002] With the progress of the economy and society, patients have more and more urgent requirements for minimally invasive surgery, due to CO 2 Pneumoperitoneum can be secondary to complications such as hypercapnia, air embolism, and blood stasis, which limits its application in children with immature tissues and organs, pregnant women, and elderly patients with underlying diseases. Pneumoperitoneum-free laparoscopy uses external mechanical tension to provide operation space for surgery, does not rely on artificial pneumoperitoneum, and reduces CO 2 Complications related to pneumoperitoneum, so that patients who have indications for minimally invasive surg...

AI Technical Summary

Problems solved by technology

[0004] The invention solves the defect in the prior art that the use of Kirschner needles to penetrate the abdominal wall for abdominal wall suspension is easy to cause secondary trauma to the patient, and provides a pneumoperitoneum-free laparoscopic suspension type abdominal wall puncture device, which uses a support arm to make an incision from the abdominal wall Enter and stretch in the abdominal cavity to support from the inner surface of the abdominal wall to prevent secondary trauma to the abdominal wall

[0005] The present invention also solves the defect that the partial suspension of the abdominal wall to form a wedge-shaped tent roof in the prior art will affect the surgical field, and provides a pneumoperitoneum-free laparoscopic suspension type abdominal wall puncture device, which can form a barrel after the support arm is stretched Shaped larger space, so that the operation has enough surgical field

[0006] The present invention also solves the defect that the suspension method in the prior art is easy to block the handle operation of the laparoscopic instrument and affects the normal operation, and provides a pneumoperitoneum-free laparoscopic suspension type abdominal wall puncture device, which adopts scattered traction The pulling rope is pulled, and at the same time, the pulling rope outside the abdominal wall is expanded through a part with an enlarged size. The pulling rope is fixed on the bracket above the plane of the abdominal wall to prevent the pulling rope from being blocked by the handle of the instrument.
