Description

Minimally invasive fascia closer

Technical Field

The invention relates to the technical field of medical instruments, in particular to a minimally invasive fascia closer.

Background

In recent years, minimally invasive surgery with the advantages of small wound, quick recovery, high cure rate and the like has been developed rapidly, and laparoscopic surgery is used as a representative of minimally invasive surgery, and is widely applied to the field of surgical operations, involving a plurality of diseases and operations.

To accommodate closure of the incision at the abdominal wall puncture site in this field, surgical incisions have been sutured using fascia sealers. When the suture needle is used, the suture needle with the suture thread passes through the TPU film sheet, and when the suture needle is pulled out, the suture thread is extruded by the elastic liner layer, so that one end of the suture thread is limited on one wing plate, the suture thread can not exit along with the suture needle, and after the other end of the suture thread is led out of the body, the suture thread can be knotted under direct vision.

However, in clinical practice it has been found that often due to the thicker fat layer on the patient's abdominal wall, the greasy grease prevents the suture from being pinched by the TPU film sheet when the suture probe is pulled out, often resulting in suture failure.

Disclosure of Invention

The invention aims to provide a minimally invasive fascia closer which can be suitable for patients of various sizes, avoid the condition that suture lines cannot be clamped due to the fat layers of the abdominal walls of the patients, and improve the success rate of suture.

The technical scheme adopted for solving the technical problems is as follows:

The minimally invasive fascia closer comprises an introducer and a suture probe, wherein the introducer comprises a pull rod, the pull rod is hinged with two movable wing plates which are correspondingly matched, and each movable wing plate is internally provided with a TPU film piece; TPU film piece in every activity pterygoid lamina all includes TPU film piece and lower TPU film piece, goes up TPU film piece and presss from both sides between the TPU film piece down and is equipped with the clamp line piece, presss from both sides line piece middle part and is equipped with and sews up the probe and form complex pinhole, presss from both sides line piece along pinhole circumferencial direction and is equipped with a set of slot, and the slot is linked together with the pinhole, and the slot can form the cooperation with the seam.

The invention can also have another scheme:

the minimally invasive fascia closer comprises an introducer and a suture probe, wherein the introducer comprises a pull rod, the pull rod is hinged with two movable wing plates which are correspondingly matched, and each movable wing plate is internally provided with a TPU film piece; the TPU film piece in every activity pterygoid lamina all is equipped with the recess along transversely, and the recess is embedded to be equipped with presss from both sides the line piece, presss from both sides the line piece middle part and is equipped with and form complex pinhole with the suture probe, presss from both sides the line piece and is equipped with a set of slot along pinhole circumferencial direction, and the slot is linked together with the pinhole, and the slot can form the cooperation with the suture line.

Preferably, the wire clamping sheet in the two schemes adopts stainless steel or titanium alloy materials.

The invention has the beneficial effects that the suture probe with the suture thread is inserted into the movable wing plate and passes through the needle hole of the thread clamping piece, when the suture probe is pulled out, the suture thread is clamped by the groove, and even if the abdominal wall of a patient has a thick fat layer, the suture thread can be reliably clamped, thereby ensuring the success rate of the suture.
