Abstract

The invention relates to a minimally invasive surgical instrument for implanting the artificial chordae through the apex cordis for repairing the mitral regurgitation. The minimally invasive surgical instrument comprises clamp forceps, a catheter and a flanged joint which are connected in sequence, as well as an opening-closing pull rod, a locking push rod and a puncture guide wire, wherein the clamp forceps are round-head clamp forceps, and comprise a movable clamp forceps part, a fixed clamp forceps part and a fixed clamp forceps base, the movable clamp forceps part is provided with a bending guide hole realizing axial inlet and radial outlet, and the fixed clamp forceps part is provided with a radial V-shaped through groove; the puncture guide wire can sequentially penetrate through the flanged joint, the catheter, the fixed clamp forceps base, the bending guide hole of the movable clamp forceps part, and the radial V-shaped through groove of the fixed clamp forceps part, and penetrates out from the radial V-shaped through groove of the fixed clamp forceps part; the locking push rod sequentially passes through the flanged joint, the catheter and the fixed clamp forceps base to reach the radial V-shaped through groove of the fixed clamp forceps part. The minimally invasive surgical instrument is small in size, compact in structure, and easy to operate in surgeries, therefore, the operation time is greatly shortened, the operation efficiency and safety are improved, the operation wound is small, the operation is safe and convenient, and good operation effects are achieved.

Description

The Minimally Invasive Surgery apparatus of mitral incompetence is repaired through apex of the heart implantable artificial chordae tendineae

Technical field

The present invention relates to medical apparatus and instruments, particularly relate 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 big, risk is high, especially for latter stage at end, the patient of heart failure pooling function mitral incompetence is difficult to tolerance surgical operation, thus the operation that Wicresoft repairs mitral incompetence now clinically has very big demand. The Wicresoft of existing application and clinic repairs mitral incompetence technology and mostly exists abroad, does not also have the domestic Wicresoft with independent intellectual property right to repair Bicuspid valve technology. External technology withSystem, MOBIUS system and DS1000 system etc. are main product, and they have respective defect.System induction system distance, needing 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, but success rate is relatively low, and vacuum suction capture systems is likely to result in serious losing blood. And DS1000 system is also because the reason such as expensive exists certain defect.

Summary of the invention

The purpose of the present invention, it is simply that in order to solve the problems referred to above, it is provided that 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, present invention employs techniques below scheme: a kind of Minimally Invasive Surgery apparatus repairing mitral incompetence through apex of the heart implantable artificial chordae tendineae, including 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 including active clamp, fixing clamp and fixation clamps holder, the curved guide hole that active clamp has axially to enter, radially goes out, fixing clamp has radially 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 direction V-type groove of fixing clamp and pass from the radial direction V-type groove of fixing clamp; Described locking push rod passes through the radial direction 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.

The present invention is 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 pressing from both sides face hurtless measure toothrow, effectively catch, puncture seal wire and artificial cords bends and passes mitral leaflet via the curved guide hole within active clamp and carries out chordae tendineae reconstruction, perform the operation easy to use, and safe and reliable, cost obtains corresponding reduction.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram of the present invention;

Fig. 2 is the sectional structure schematic diagram of the present invention;

Fig. 3 is local (the when clamp opens) perspective view of the present invention.

Detailed description of the invention

Referring to Fig. 1, coordinate referring to Fig. 2, Fig. 3, the micro-plane operating theater instruments repairing mitral incompetence through apex of the heart implantable artificial chordae tendineae of the present invention, including 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 including active clamp 11, fixing clamp 12 and fixation clamps holder 13, the curved guide hole 14 that active clamp therein has axially to enter, radially goes out, fixing clamp has radially V-type groove 15. Puncture seal wire 6 to pass through bump joint, conduit, fixation clamps holder, the curved guide hole of active clamp, the radial direction V-type groove of fixing clamp and pass from the radial direction V-type groove of fixing clamp; Locking push rod 5 passes through the radial direction V-type groove of bump joint, conduit, the fixing clamp of fixation clamps holder arrival. Medial surface at active clamp and fixing clamp is respectively equipped with hurtless measure toothrow 16.

The switchable general surgical operating instrument handle of bump joint 3 in the present invention.

Folding pull bar 4 front end is connected with connecting pin 7, and connecting pin 7 is arranged in chute 8.

The present invention can pass through bump joint 3 and transfer general surgical device handle; Handle has two kinds of functions:

1. control folding pull bar 4, it is achieved apparatus folding;

2. control locking push rod 5 realizes seizure and the locking of 6 to puncture seal wire.

Adjustable cramp 11 top has curved guide hole 14, communicates with shell 2, bump joint 3; Puncturing seal wire 6 guides artificial cords through bump joint 3 via curved guide hole 14, reaches active clamp 11 and presss from both sides face place with fixing clamp 12, thus passing perpendicularly through mitral leaflet.

Fixing clamp 12 front end has radially V-type groove 15, promotes locking push rod 5 can catch and lock the puncture seal wire 6 through mitral leaflet.

Mitral valve tissue will not be caused wound by the hurtless measure toothrow 16 in the present invention when catching mitral leaflet, and makes smooth mitral valve leaflet be easier to be captured.

The present invention can install limit base when transferring follow-up general surgical operating instrument handle, pulls the destruction not resulting in apparatus during apparatus.
