Description

Puncture suture needle

Technical Field

The utility model relates to a surgical operation apparatus field, concretely relates to novel puncture suture needle.

Background

In the current clinical endoscopic surgery, if the peritoneum and the fascia layer are not sutured, the possibility of incomplete intestinal obstruction caused by the hernia of omentum or intestinal canal in the abdominal cavity or local adhesion is easily formed, the problems of puncture hole bleeding, puncture hole hernia and the like are often caused, and the pain of a patient is increased due to the occurrence of complications. In order to solve the problem, the inventor filed a prior application in 2016, application No. 201620970368.5, entitled novel utility model application of knot pusher to overcome the above problems, and further found that, in the existing suturing process, after the suture thread is inserted into the abdominal cavity by the suture needle, if the abdominal cavity wall of the patient is tighter than the clamping force of the silica gel sheet in the movable wing plate of the suturing device, the suture thread is easy to withdraw when withdrawing the suture needle, so that the subsequent suturing can not be completed, and the patient is further painful,

however, the present inventors have also provided a puncture suture needle with a detachable needle head, but the needle has a relatively high processing cost and a slightly complicated structure, so how to provide a puncture suture needle with a lower cost and a more easy operation becomes a problem to be solved by the present inventors.

Disclosure of Invention

The utility model provides a puncture suture needle aiming at the defects of the prior art, which comprises a puncture needle cylinder, a threading device and a thread pushing rod, wherein the threading device and the thread pushing rod are matched with the puncture needle cylinder; the wire pushing rod comprises a rear needle handle II and a wire pushing rod body connected to the rear needle handle II; adopt the puncture suture needle of this kind of structure, before the puncture, utilize the threading apparatus to reserve the stylolite in the cylinder for the puncture, after cylinder cooperation pusher inserts the abdominal cavity for the puncture, use and push away the line pole and push into in activity pterygoid lamina and the protective sheath middle space that the pusher corresponds with some stylolite, the utility model discloses the knot pusher body cooperation that applies for earlier with the inventor uses, and it is external to take out through the stylolite in the middle of pusher with activity pterygoid lamina and the protective sheath, realizes the mesh of sewing up in vitro, is applicable to among the minimally invasive laparoscopic surgery tissue and draws near and incision percutaneous closure.

The utility model discloses a concrete technical scheme is:

a puncture suture needle comprises a puncture needle cylinder, a threading device and a thread pushing rod, wherein the threading device and the thread pushing rod are matched with the puncture needle cylinder; the thread pushing rod comprises a rear needle handle II and a thread pushing rod body connected on the rear needle handle II,

the maximum diameter of the thread passing rod and the thread pushing rod body is smaller than the diameter of the hollow part of the needle cylinder for puncture; and the length of the needle cylinder is longer than that of the needle cylinder for puncture;

the front needle handle, the rear needle handle I and the rear needle handle II can be connected in a matching way;

the top end of the threading rod is provided with a wire hanging device which is a wire hanging ring or a wire hanging hook;

furthermore, a protective device can be arranged at the front end of the needle head, the protective device is a protective block which is made of elastic materials and is matched with the needle head, and a through hole with the same diameter as the needle rod is arranged in the center of the protective device; the front needle handle is made of transparent material.

Before puncture, firstly inserting the threading device into the needle cylinder for puncture, enabling the thread hanging device arranged at the top end of the threading rod to penetrate out of the needle head at the front end of the needle cylinder, at the moment, threading or hanging the suture thread on the thread hanging device, pulling the rear needle handle I of the threading device, observing the condition that the suture thread in the front needle handle moves along with the threading device, ensuring that the suture thread does not fall off, finally pulling the threading rod out of the needle cylinder for puncture, taking the suture thread out of the needle cylinder for puncture, puncturing the puncture suture needle threaded with the suture thread into the body through the adaptive thread end pusher, pushing the thread pushing rod body into the needle cylinder for puncture after puncture is finished, pushing the thread pushing rod body in the process, extruding and driving the suture thread to descend along with the thread, pushing a part of the suture thread into a gap between the movable wing plate of the thread end pusher and the protective sleeve, and ensuring that the part of the suture thread can be taken out of the body again along with the thread end pusher, and finishing the subsequent sewing.

In order to avoid that the needle part punctures medical care personnel during threading, the inventor designs the protection device, and after the protection device is sleeved on the needle, the thread hanging device can be exposed out through the central through hole of the needle, so that the operation of the medical care personnel is convenient;

in the use process, after the needle head of the puncture suture needle penetrates through the silica gel sheet in the movable wing plate of the knot pusher, the needle head can abut against the hard gasket on the movable wing plate, the suture line can not be pushed out when the line pushing rod pushes the line for preventing the needle head from being completely contacted with the hard gasket, the opening communicated with the needle head and the cavity of the needle rod is further arranged at the intersection of the needle head and the needle rod, the suture line can be smoothly pushed out when the line pushing rod pushes the line, the whole device is safer to use, and the puncture suture needle is suitable for tissue approximation and percutaneous closure of the incision in the minimally invasive endoscopic surgery.

To sum up, adopt the puncture suture needle of this kind of structure, before the puncture, utilize the threading apparatus to reserve the stylolite in the cylinder for the puncture, insert the abdominal cavity with cylinder cooperation pusher for the puncture after, use and push away the line pole and push into in the activity pterygoid lamina and the protective sheath space in the middle of the pusher corresponds with some stylolite, the utility model discloses the knot pusher body cooperation that applies for earlier with the inventor uses, takes out the stylolite in the middle of activity pterygoid lamina and the protective sheath in vitro through the pusher, realizes the purpose of sewing up in vitro, is applicable to among the minimally invasive laparoscopic surgery tissue and draws near and incision percutaneous closure.
