Abstract
Repair a Minimally Invasive Surgery apparatus for mitral incompetence through apex of the heart implantable artificial chordae tendineae, comprise clamp, conduit and bump joint that order is connected, and folding pull bar, locking push rod and puncture seal wire; Clamp is round end clamp, and comprise active clamp, fixing clamp and fixation clamps holder, the curved guide hole that active clamp has axially to enter, radial direction goes out, fixing clamp has radial V-type groove; Puncture seal wire can pass through bump joint, conduit, fixation clamps holder, the curved guide hole of active clamp, the radial V-type groove of fixing clamp passing from the radial V-type groove of fixing clamp; Locking push rod passes through the radial V-type groove of bump joint, conduit, the fixing clamp of fixation clamps holder arrival.This utility model apparatus is small, compact conformation, and operation technique is simple, and highly shortened operating time, improve procedure efficiency and safety, operation wound is little, safe ready, can reach better surgical effect.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly relates to a kind of Minimally Invasive Surgery apparatus repairing mitral incompetence through apex of the heart implantable artificial chordae tendineae.
Background technology
In the prosthesis for the treatment of mitral incompetence, traditional surgery wound is large, risk is high, particularly for patient's very difficult tolerance surgical operation of heart failure pooling function mitral incompetence in latter stage at end, thus there is very large demand to the operation of Wicresoft's reparation mitral incompetence clinically now.Existing application and clinical Wicresoft repair mitral incompetence technology and mostly exist abroad, also do not have the domestic Wicresoft with independent intellectual property right to repair Bicuspid valve technology.External technology with
system, MOBIUS system and DS1000 system etc. are main product, and they have respective defect.
system induction system distance, need to wear out interatrial septum, catch Bicuspid valve and need the long period and expensive, although MOBIUS system is through the apex of the heart, induction system is shorter, and success rate is lower, and vacuum suction capture systems may cause serious losing blood.And DS1000 system is also because there is certain defect in the reason such as expensive.
Utility model content
The purpose of this utility model, exactly in order to solve the problem, provides a kind of Minimally Invasive Surgery apparatus repairing mitral incompetence through apex of the heart implantable artificial chordae tendineae.
In order to achieve the above object, this utility model have employed following technical scheme: a kind of Minimally Invasive Surgery apparatus repairing mitral incompetence through apex of the heart implantable artificial chordae tendineae, comprise clamp, conduit and bump joint that order is connected, and folding pull bar, locking push rod and puncture seal wire; Described clamp is round end clamp, and comprise active clamp, fixing clamp and fixation clamps holder, the curved guide hole that active clamp has axially to enter, radial direction goes out, fixing clamp has radial V-type groove; Described puncture seal wire can pass through bump joint, conduit, fixation clamps holder, the curved guide hole of active clamp, the radial V-type groove of fixing clamp passing from the radial V-type groove of fixing clamp; Described locking push rod passes through the radial V-type groove of bump joint, conduit, the fixing clamp of fixation clamps holder arrival.
The medial surface of described active clamp and fixing clamp is respectively equipped with hurtless measure toothrow.
This utility model compared with prior art, there is following positive effect: reasonable in design, left ventricle is entered through the apex of the heart, the friction with mitral leaflet can be strengthened by folder face hurtless measure toothrow, effectively catch, puncture seal wire and artificial cords bend via the curved guide hole of active clamp inside and pass mitral leaflet carries out chordae tendineae reconstruction, performs the operation easy to use, and safe and reliable, cost obtains corresponding reduction.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model;
Fig. 3 is local of the present utility model (when clamp opens) perspective view.
Detailed description of the invention
See Fig. 1, coordinate see Fig. 2, Fig. 3, the Minimally Invasive Surgery apparatus repairing mitral incompetence through apex of the heart implantable artificial chordae tendineae of the present utility model, comprises clamp 1, conduit 2 and bump joint 3 that order is connected, and folding pull bar 4, locking push rod 5 and puncture seal wire 6.Clamp 1 is round end clamp, and comprise active clamp 11, fixing clamp 12 and fixation clamps holder 13, the curved guide hole 14 that active clamp wherein has axially to enter, radial direction goes out, fixing clamp has radial V-type groove 15.Puncture seal wire 6 can pass through bump joint, conduit, fixation clamps holder, the curved guide hole of active clamp, the radial V-type groove of fixing clamp passing from the radial V-type groove of fixing clamp; Locking push rod 5 passes through the radial V-type groove of bump joint, conduit, the fixing clamp of fixation clamps holder arrival.Hurtless measure toothrow 16 is respectively equipped with at the medial surface of active clamp and fixing clamp.
The switchable general surgical operating instrument handle of bump joint 3 in this utility model.
Folding pull bar 4 front end and connecting pin 7 are connected, and connecting pin 7 is arranged in chute 8.
This utility model to be transferred general surgical device handle by bump joint 3; Handle has two kinds of functions:
1. control folding pull bar 4, realize apparatus folding;
2. control locking push rod 5 realize to puncture seal wire 6 seizure and locking.
Adjustable cramp 11 top has curved guide hole 14, communicates with shell 2, bump joint 3; Puncture seal wire 6 guides artificial cords to pass bump joint 3 via curved guide hole 14, reaches active clamp 11 and presss from both sides face place with fixing clamp 12, thus pass perpendicularly through mitral leaflet.
Fixing clamp 12 front end has radial V-type groove 15, promotes locking push rod 5 and can catch and lock the puncture seal wire 6 through mitral leaflet.
Hurtless measure toothrow 16 in this utility model can not cause wound to mitral valve tissue when catching mitral leaflet, and smooth mitral valve leaflet is more easily captured.
This utility model can mounting limit seat when transferring follow-up general surgical operating instrument handle, pulls the destruction can not causing apparatus during apparatus.
