Abstract
The utility model provides a minimally-invasive heart valve ring suture traction device. The device is characterized by comprising a traction hook and a traction line, wherein the traction hook comprises an arc-shaped traction hook body, a cylindrical long protrusion is arranged at the center of the outer edge side of the traction hook body, the cylindrical long protrusion is connected with the traction line, and short protrusions are arranged on portions of the outer edge side of the traction hook body, which are located on two sides of the cylindrical long protrusion. The device has the advantages that percutaneous approaching is achieved; instrument fixation is achieved; the device and a suture can be in free sliding contact and can be effectively pulled by each other; no damage is caused to tissue inside thoraxes; the device is convenient to install.
Description
Technical field
This utility model relates to the traction apparatus of a kind of minimally invasive heart valve surgery art mesopetalum circumferential weld line.
Background technology
When carrying out the minimally invasive heart valve surgery, most of handle hole all is positioned at the right side thorax, and wherein thoracoscope enters thoracic cavity by near the perforate midaxillary line of right side, and the main operation hole is between the right side horizontal midclavicular line of the 4th intercostal and anterior axillary line.While being expert at Bicuspid valve or Tricuspid valve reparation, needing first to enclose at lobe ring place interrupted suture one, and all lobe circumferential weld lines are drawn and suspend in midair in order outward by main operation hole lead body, the lobe ring can be launched be convenient to like this exposure and the valve forming operation of structure under lobe.Specific locus (part lobe circumferential weld line blocks between valve and thoracic cavity camera lens) causes under the thoracoscope visual field having all the time part lobe circumferential weld line to block valve, has hindered the exposure of field of operation and the accurate operation of valve surgery.
Conventional drag hook can only enter from the main operation hole, due to limited space, can further affect on the contrary the operation technique in main operation hole.
Conventional drag hook needs surgical staff manually fixing, and this will increase surgical staff quantity, and poor stability, be not suitable for prolonged traction.
Summary of the invention
The technical problems to be solved in the utility model is the circumferential weld of the lobe for the minimally invasive heart valve surgery line traction apparatus that can not counteract operation technique.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide the traction apparatus of a kind of minimally invasive heart lobe circumferential weld line, it is characterized in that: comprise hook and draught line, wherein, hook comprises the hook main body of arc, there is the long projection of a cylindricality in the outer edge side central authorities of this hook main body, and the long projection of cylindricality is connected with draught line, are positioned at the outer edge side of hook main body on the part of the protruding both sides of cylindricality length and are arranged with short projection.
Preferably, the radian of described hook main body is π/3rad, and arc length is 3cm.
Preferably, the long protruding length of described cylindricality is 1cm.
Preferably, described short projection always has 6, and 3 described short projections are one group, and two groups of described short projections lay respectively at the long protruding both sides of described cylindricality.
Preferably, the length of described short projection is 0.5cm.
Preferably, described short projection reaches between any two described short projection and all equates with the spacing between the long projection of described cylindricality.
Preferably, a corner of described short projection is arc.
Preferably, the length of described draught line is 30cm.
This utility model provides the traction apparatus of a kind of minimally invasive heart lobe circumferential weld line, this device: 1, percutaneous approach; 2, apparatus is fixed; 3 with suture between not only can be free to slide and contact but also can effectively draw; 4, to thorax inner tissue not damaged; 5, install convenient.
The accompanying drawing explanation
The structural representation of a kind of minimally invasive heart lobe circumferential weld line traction apparatus that Fig. 1 provides for this utility model;
The structural representation that Fig. 2 is hook.
The specific embodiment
For this utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
As shown in Figure 1, the minimally invasive heart lobe circumferential weld line traction apparatus that this utility model provides is comprised of hook and draught line 1, and simple in structure, low to material requirements, generalization is strong.
In conjunction with Fig. 2, hook comprises the hook main body 4 of arc, and the radian of hook main body 4 is π/3rad, and arc length is 3cm, and radian length and annulus of mitral valve, tricuspid annulus are applicable to, and can play the effect that effective traction exposes field of operation.There is the long projection 2 of a cylindricality in outer edge side central authorities in this hook main body 4, and the length of the long projection 2 of this cylindricality is 0.5cm, and the long projection 2 of cylindricality is connected with draught line 1.The length of draught line 1 is 30cm, and the rear whole device of tractive draught line 1 is in the mechanics steady statue, can the generating means spin due to different thread tension differences, the runaway condition such as amesiality.At the outer edge side of hook main body 4, be positioned on the part of long protruding 2 both sides of cylindricality respectively be arranged with 3 short protruding 3, short protruding 3 length is 0.5cm, can play the effect of effective traction, also can separate the valve suture, prevents between suture being wound around cover line impact operation.A corner of short protruding 3 is arc, can avoid damaging thorax inner tissue.
Use step of the present utility model is:
Step 1, the device that this utility model is provided are put into the thoracic cavity, right side by the main operation hole;
Step 2, in appropriate location, thoracic cavity, right side with micro-wound percutaneous puncture deep thread catcher puncture, under the thoracoscope guiding, by draught line 1, by puncturing hole, tick external;
Step 3, will block at thoracic cavity camera lens and intervalvular part suture and be placed on hook, notice that suture is 6 short uniform distributions of protruding 3;
Step 4, tractive draught line 1, retract lobe circumferential weld line, and thoracoscope visual field mesopetalum ring valve is fully exposed, and draught line 1 end can be fixed on the extracorporeal surgery list by vascular forceps;
Step 5, complete the vascular forceps of after valve surgery operation, unclamping draught line 1 end, take out traction apparatus from the main operation hole.
