Description

Multifunctional retractor fixator

Technical Field

The invention relates to the technical field of medical instruments, in particular to a multifunctional retracting fixator.

Background

Retractor holders are used in surgical procedures. The existing sharp instrument for pulling the channel membrane of the fixator has the defect that the channel membrane is not easy to be found after being punctured and falling into the abdominal cavity; when a small incision operation is performed, an extra assistant is needed to hold the endoscope, and the labor burden is increased. The existing external ring of the retractor fixator is not strong enough in clinical use, which causes the shape of the retracted wound to be irregular, and the operation is limited.

In order to increase the retraction strength of the outer ring, there are two schemes, one is to add hard wire materials such as steel wire in the hollow hole of the outer ring, and the second scheme is to hook the incision using the retraction fixer in two or four symmetrical directions by additionally using a metal rake hook to assist in retraction.

The existing endoscope fixing ring comprises an upper parallel ring, a lower parallel ring, a large ring, a small ring and a connecting rib, wherein the large ring is sleeved on a retraction fixer, and the small ring is used for fixing an endoscope. The fixing ring has the advantages of high manufacturing technology difficulty, low firmness, high difficulty in matching with a retractor fixer and possibility of loosening.

In view of the above drawbacks, it is desirable to design a multifunctional retracting fixture.
