Abstract
The utility model provides a kind of suture tightening device, including is used as the incoming line of suture access location；For wind suture, can only single direction rotation spool；For the rotary part for driving spool to rotate；Suture for incoming line to be come out guides the guide rod to spool.In use, rotary part drives spool rotation, the line that four incoming lines come out is guided through guide rod after passing through, is wound on spool.Four suture length outside device constantly shorten, final to pull sticking patch accumulation, realize suture purpose.After suture, which is tightened to gap defect, to be sewn, rotate counterclockwise is threaded the core bar of head, core bar is separated with rotary part shell.Then together withdrawn from vitro together with rotary part and core bar.The suture tightening device that the utility model is provided can take in suture unnecessary in sewing process, while ensureing suture strength, it is to avoid suture is not compacted, so as to realize the therapeutic effect of intervention suture, safely and effectively.
Description
Technical field
The utility model is related to a kind of suture tightening device, intervenes and sutures for bicuspid valve, tricuspid valve, acleistocardia etc.
Field.
Background technology
For the intervention illness such as sutural treatment gap class defect or valve repair, existing sutural treatment has Mitralign
System (bicuspid valve sewing system), it mainly by pushing ligation set, is constantly tightened up suture, cut finally by interventional method
Break this two sutures, ligation set clamping the end of a thread, reaches fastening effect.
But, because the end of a thread is open, there is the risk that suture is released in Mitralign systems.
Utility model content
The technical problems to be solved in the utility model is in intervention sutural treatment, how to ensure suture strength, it is to avoid seam
Line is released.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide a kind of suture tightening device, and it is special
Levy and be：Including
It is used as the incoming line of suture access location；
For wind suture, can only single direction rotation spool；
For the rotary part for driving spool to rotate；
Suture for incoming line to be come out guides the guide rod to spool.
Preferably, the incoming line quantity is consistent with suture quantity.
Preferably, the spool is provided with annular groove.
Preferably, the spool periphery is provided with a spool tooth turned clockwise, and spool side can revolve counterclockwise provided with one
Turn the latch of 3-5 degree.
Preferably, the spool periphery is provided with the spool tooth of a rotate counterclockwise, and spool side can dextrorotation provided with one
Turn the latch of 3-5 degree.
Preferably, the rotary part inner core is provided with hollow screwed hole, screwed hole provided with carrying that a gap coordinates
The core bar of thread head, core bar top is threaded on screwed hole.
In use, rotary part drives spool to turn clockwise, the line that four incoming lines come out draws after passing through through guide rod
Lead, be wound on spool.Four suture length outside device constantly shorten, final to pull sticking patch accumulation, realize suture purpose.
After suture, which is tightened to gap defect, to be sewn, rotate counterclockwise is threaded the core bar of head, makes outside core bar and rotary part
Shell is separated.Then together withdrawn from vitro together with rotary part and core bar.
The suture tightening device that the utility model is provided can take in suture unnecessary in sewing process, ensure simultaneously
Suture strength, it is to avoid suture is not compacted, so as to realize the therapeutic effect of intervention suture.
Compared with prior art, the suture tightening device that the utility model is provided has the advantages that：
1st, tightening up for intervention suture is realized by rotating in vitro, is optimal sewing effect；
2nd, realize that unnecessary suture is collected after intervention suture by rotating in vitro, it is to avoid caused by the end of a thread is exposed thrombus
Accumulation and drift；
3rd, the risk come off in the absence of device, safely and effectively.
Brief description of the drawings
The suture tightening device front view that Fig. 1 provides for the present embodiment；
The suture tightening device top view that Fig. 2 provides for the present embodiment；
Fig. 3 is rotary part structural representation；
The suture tightening device operation principle schematic diagram that Fig. 4 provides for the present embodiment.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
The suture tightening device front view that Fig. 1 provides for the present embodiment, described suture tightening device includes：
Four incoming lines, the first incoming line 1 and the second incoming line 2 are located at side, are used as line A and line B access location；The
Three incoming lines 3 and the 4th incoming line 4 are located at opposite side, are used as line C and line D access location；Both sides incoming line is symmetrical arranged.
Spool 7, which is provided with annular groove, be easy to suture is regular to tighten up.
Rotary part 6, for driving spool 7 to rotate.
Two guide rods 5, are symmetrical arranged, and the line for both sides incoming line to be come out is guided to spool 7.
With reference to Fig. 2, the periphery of spool 7 is provided with the spool tooth 9 turned clockwise, and the side of spool 7 is provided with a latch 8.Latch 8 is
One can be with the movable part of rotate counterclockwise 3-5 degree.It can be seen that, because spool tooth 9 is into zigzag, when turning clockwise,
Pass through latch 8；During rotate counterclockwise, spool tooth 9 is blocked by latch 8.I.e. spool 7 can only turn clockwise.
With reference to Fig. 3, the inner core of rotary part 6 is provided with hollow screwed hole, places the core for being threaded head that a gap coordinates
Bar 61, core bar 61 top is threaded on screwed hole；When rotary part 6 rotates, the presence of core bar 61 ensures pair of rotation
It is neutral.
With reference to Fig. 4, in use, rotary part 6 drives spool 7 to turn clockwise, after the line that four incoming lines come out is passed through
Guide, be wound on spool 7 through guide rod 5.Four suture A, B, C, D length outside device constantly shorten, and final pull is mended
Piece is accumulated, and realizes suture purpose.After suture, which is tightened to gap defect, to be sewn, rotate counterclockwise is threaded the core bar of head
61, core bar 61 is separated with the shell of rotary part 6.Then together withdrawn from vitro together with rotary part 6 and core bar 61.
When the method by accessing rotation, unnecessary line is taken in into the present apparatus, the effect for tightening up stitching devices can be reached,
Meanwhile, further two lateral extents of suture in continuous tightening process, realizes the purpose of suture.
