Embodiment
The invention will be further described for explanation and embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 8, a kind of ventricle connection component of implanted artificial blood pump, including suture ring 1, suture ring seat
2nd, pivot pin 3 and clamp cam spanner 4, wherein, the clamp cam spanner 4 is arranged on the suture ring seat 2 by the pivot pin 3
On, the suture ring seat 2 is equipped with passes through suture 8 around its circumferentially disposed sewing hole 5, the suture ring 1, suture ring seat 2
Connection, the suture 8 pass through the sewing hole 5.
As shown in Figures 1 to 8, the suture ring seat 2 is equipped with the first mounting hole 6, and the clamp cam spanner 4 is equipped with
Second mounting hole 7.
As shown in Figures 1 to 8, the suture ring seat 2 is equipped with clamping part, and the clamping part is equipped with cam path, described
Clamp cam spanner 4 is arranged in the cam path.
As shown in Figures 1 to 8, the both sides of the clamping part are equipped with the clamp cam spanner 4.
As shown in Figures 1 to 8, the ventricle connection component further includes blood pump 22, and the blood pump 22 is connected with blood pump outlet
Pipe 9 and blood pump inlet tube 21, the blood pump inlet tube 21 are threaded through on the suture ring 1 and suture ring seat 2.
As shown in Figures 1 to 8, the clamp cam spanner 4 drives the suture ring seat 2 to clamp the blood pump inlet tube
21。
As shown in Figures 1 to 8, the blood pump inlet tube 21 and the suture ring 1 are interference fit.
A kind of ventricle connection component of implanted artificial blood pump provided by the invention, easy to operate, size is smaller, improves
Procedure efficiency and the difficulty for reducing implant surgery.
A kind of assembling process of the ventricle connection component of implanted artificial blood pump provided by the invention is：
The first step, as shown in Fig. 2, clamp cam spanner 4 and axis pin 3 are assembled together with suture ring seat 2 first, reuses seam
Zygonema 8 unites by a seam suture ring 1 and suture ring seat 2 as an entirety, becomes ventricle connector.During this, suture ring
Seat 2 forms ventricle connector together with 1 tight suture of suture ring, and sealing prevents blood leakage.
Second step, as shown in figure 3, being sutured the ventricle connector that the suture described in the first step is completed using suture 8
Ring periphery and heart apex 14 are closely stitched together, and sealing prevents blood leakage.Then by the endoporus of suture ring in the heart
Suitable hole is opened on point allows inlet tube 21 to be smoothly inserted into ventricle.
3rd step, as shown in figure 4, clamp cam spanner 4 is pulled maximum open position with hand, the blood pump of blood pump 22 is entered
Mouth pipe 21 is inserted into the hole of ventricle connector, by rotating blood pump along F directions（Manual pumps）22, until 9 turns of blood pump outlet
Move suitable surgery location to stop operating, then again turned to clamp cam spanner 4 in suture ring seat 2 with hand, with suture
The deformation force of ring seat 2 clamps blood pump inlet tube 21, so completes the positioning and clamping work of blood pump 22.Finally use suture
First mounting hole 6 and the second mounting hole 7 are fixed, clamp cam spanner 4 and suture ring seat 2 are fixed, to prevent clamp cam
Spanner 4 loosens.
How to ensure to seal the necessary function that anti-bleeding is ventricle connector, as shown in figure 5, when blood pump 22 is inserted into suture ring
1 and suture ring seat 2, complete positioning and clamping.At this time, the outside diameter of the perforate of suture ring 1 and blood pump inlet tube 21 is interference fit,
Since suture ring 1 is generally made of terylene cloth material and has certain elasticity, blood can be tightly embraced in location A when interference fit
Pumping intake piping 21, plays the role of the anti-bleeding of sealing.
Suture ring seat 2 and clamp the principle of blood pump inlet tube 21, as shown in fig. 6, being to utilize clamp cam spanner 4 by suture ring
2 crimps of seat, that is, clamp gap delta and maximum be at Fig. 6 positions, be at this time inserted into blood pump inlet tube 21, convex when clamping
When wheel spanner 4 pulls Fig. 7 positions, clamping gap delta can be in minimum value, suture ring seat 2 at this time and just clamp blood pump inlet tube 21
Firmly.
Suture ring seat 2 and clamp also another mutation of blood pump inlet tube 21, as shown in figure 8, being further added by one in left side
Clamp cam spanner 4, forms biconvex wheel spanner and blood pump inlet tube 21 is clamped.So chucking power meeting bigger, and can protect
Card one loosens, another still has clamping action.
A kind of ventricle connection component of implanted artificial blood pump provided by the invention, compact dimensions, radial dimension compare blood pump
It is small, axial width moderate dimensions.Greatly extend operative space.
The ventricle connection component and its assemble method of a kind of implanted artificial blood pump provided by the invention have the following advantages：
1. shortening operating time, implant surgery efficiency is improved.The present invention is easily adjusted artificial blood in suture and clamping process is done
The positioning of pump and convenient clamping, greatly shorten operating time and improve efficiency.
2. increase the operating space of implant surgery.Ventricle connector compact dimensions proposed by the present invention, required operating space
It is small, the operating space that doctor does implant surgery is added, facilitates surgical procedure, reduces operation risk.
3. the anti-bleeding function of outstanding sealing.The present invention proposes that ventricle connector is sewn onto on the apex of the heart using suture,
And suture ring does the anti-bleeding of sealing, the outstanding sealing completed in artificial blood pump implant surgery is done with inlet tube interference fit
Anti- bleeding requirement.
Above content is that a further detailed description of the present invention in conjunction with specific preferred embodiments, it is impossible to is assert
