Description
Technical field
The present invention relates to field of medical technology, especially a kind of tissue for surgical work closes instrument.
Background technique
Surgery intervention operation is needed in tissue penetration or notch.Such as it is typically just worn including puncture needle through thoracoscopic operation
Thorn tissue is simultaneously inserted into conduit to keep the opening state of aperture, surgical device could by be intubated enter target position under tissue into
Row operation.It further include especially careful sharp valve repair through thoracoscopic cardiac surgery.The operation is needed from patient's intercostal
Aperture intervention reaches the heart outer wall of patient, then forms aperture by puncturing heart outer wall, is inserted into conduit to keep aperture to beat
Open state, the cavity that the channel that intervening equipment is formed by conduit reaches in heart treat the position that heart has damaged.
It is minimally invasive through the relatively traditional surgical operation of thoracoscope surgery intervention operation, because it generally only requires out one
The opening or point of puncture of very little.However these small openings are to be difficult closed, but also are in patient's body.It is sealed by suture
It closes these openings and compares traditional surgical operation and want complicated very much, it is time-consuming and long, and cannot be guaranteed that tissue closing is complete.If group
It knits closing not exclusively, will lead to internal haemorrhage or infection.
Existing heart closed front instrument on the market, such as the patent of invention " Tissue of Publication No. US8764795B2
Closure device and method ", it is mentioned that technology form circle using being coupled multiple anchor hooks with suture
Circle, to provide the service aisle of surgery intervention operation, after the completion of surgery intervention operation, suture assembles multiple anchor hooks to group
It knits and is closed.In practice, it has been found that the anchor hook that the instrument uses will cause certain damage to tissue, the other instrument size
It is larger, it need to be conveyed by the conduit of 30F or more, this can bring biggish wound to patient.
In view of the above drawbacks, it is necessary to design the new tissue closing instrument of one kind to solve the above problems.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of tissue closing instrument.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of tissue closes instrument, including flexible knitted body, and the knitted body includes distal end umbrella and proximal end umbrella,
Wherein the umbrella cover part of the distal end umbrella and the umbrella cover part of proximal end umbrella are the hollow structure of middle opening, in the distal end umbrella
The hollow structure of hollow structure and proximal end umbrella is staggered, and passes through company between the umbrella bottom point of distal end umbrella and the umbrella bottom point of proximal end umbrella
Socket part connection.
As a preference, choked flow film is provided on the knitted body.
As a preference, implantation material system of the knitted body using nitinol alloy wire etc. with shape memory function
At.
As a preference, the choked flow film is hot-melted, is sticked using outer layer and internal layer eptfe film
It is made after conjunction processing.
As a preference, the choked flow film is the structure for coating the inside and outside wall of entire knitted body and being close to knitted body.
As a preference, the choked flow film is the umbrella cover portion for coating the umbrella cover inside and outside wall of proximal end umbrella and being close to proximal end umbrella
Point, the choked flow film is in open hollow structure as the umbrella cover of proximal end umbrella.
As a preference, the knitted body is absorbable using polylactic acid or polycaprolactone or polybutylcyanoacrylate etc.
Implantation material is made.
As a preference, the choked flow film is made of polyester or mylar suture.
As a preference, the choked flow film is close to the umbrella cover inner wall of proximal end umbrella, the umbrella of the choked flow film and proximal end umbrella
Face is equally in open hollow structure.
As a preference, the choked flow film is close to the umbrella cover of proximal end umbrella and the umbrella cover inner wall of distal end umbrella, the resistance
It is in open hollow structure as stream film and the umbrella cover of the umbrella cover of proximal end umbrella and distal end umbrella.
As a preference, the knitted body may be deformed to the cylinder of transport status, can mention for surgery intervention operation
For service aisle.
As a preference, the distal end umbrella and proximal end umbrella of the knitted body are respectively positioned at envelope by surgery intervention operation
Close the two sides of target area tissue.
The beneficial effects of the present invention are: needs of the tissue closing instrument for operation, using being mutually staggered on knitted body
, the distal end umbrella that both ends open is hollow and proximal end umbrella match, a hollow service aisle can be formed when conveying shape,
To provide service aisle for surgery intervention operation, the operation of surgery intervention operation, and the super-elasticity of knitted body itself are not influenced
Make it strut or compress to be accommodated into lesser conduit to be conveyed, therefore can reduce the damage to patient, when surgery is intervened
After operation, the shape memory function of knitted body makes braiding physical efficiency become predetermined shape, the both ends of knitted body from transport status
Umbrella cover can be fitted in the two sides of tissue, to be closed by the choked flow film built in knitted body to puncturing hole or notch, the device
The closed process of tool will not cause to damage to tissue.
