Operation incision anastomosis member, anastomosis assembly and cardiac surgery mechanical suturing device

Technical Field

The disclosure belongs to the technical field of surgical instruments, and particularly relates to an operation incision anastomosis member, an anastomosis assembly and a cardiac surgery mechanical suturing device.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

In recent years, open heart surgery has been widely developed in China, and has gradually developed towards minimally invasive surgery, endoscope and robot assistance. At present, in cardiac surgery, manual suture suturing is the most conventional operation, but the manual suture suturing can cause damage to the tissue edge of a cardiac incision and needle eye blood leakage, the tissue has large response to suture, the suturing operation time is long, the quality of the surgery is influenced, particularly, the suturing technology in thoracoscopic minimally invasive cardiac surgery has high requirements, the surgical suturing is time-consuming and difficult, and the development of the thoracoscopic cardiac surgery is seriously influenced due to the lack of a mechanical suturing device.

The existing mechanical anastomosis suturing devices applied to the surgeries of esophagus, lung, stomach and intestine, blood vessels and the like have various varieties and models, have the same principle, and have the advantages of simple, rapid, accurate and reliable operation, simple deep operation, closed or closed suturing or anastomosis and the like compared with manual suturing, and more importantly, the mechanical anastomosis suturing devices enable endoscopic surgery to be possible.

The inventors believe that existing mechanical stapling devices, while replacing the suture with absorbable staples, still result in the formation of staple eyes at the incised tissue. The heart surgery has the particularity of itself, the heart tissue is uneven, is comb-shaped mostly, and the thickness is inhomogeneous, and the incision is mostly straight line, and its content is blood to there is continuous pulsation, and it is difficult to get effects to look after moving or imitate the mechanical suturing device of intestines and stomach or lung, and the nail eye department easily takes place the blood leakage.

Disclosure of Invention

The present disclosure is directed to a surgical incision anastomosis member and a mechanical cardiac surgical suturing device, which can solve at least one of the above problems.

In order to achieve the above object, a first aspect of the present disclosure provides a surgical incision anastomosis member, including an arcuate support bar, two ends of the arcuate support bar are respectively connected with a pressing plate, the two pressing plates are oppositely disposed, opposite side surfaces of the pressing plates have conical protrusions, the arcuate support bar can provide an elastic force for hindering movement when the two pressing plates approach or depart from each other;

the arched supporting rod is connected with the lock catch, and the lock catch can lock the arched supporting rod after the two pressing plates press tissues to be sutured so as to limit the deformation of the arched supporting rod.

A second aspect of the present disclosure provides a cardiac surgery mechanical suturing device, including a plurality of surgical incision anastomosis members, which are arranged side by side and end-face-fitted, and fixedly connected.

A third aspect of the present disclosure provides a mechanical suture apparatus for cardiac surgery, including an operation incision anastomosis member and an acting member, the acting member has two headrests, the two headrests are respectively inserted into the fastening edges on the outer sides of the pressing plates, and the headrests can transmit the driving force of the acting member to drive the pressing plates to open and close.

The beneficial effects of one or more of the above technical solutions are as follows:

the combination of two pressing plates, an arched supporting rod and a lock catch is adopted in the heart surgery operation, the pressing plates can be used for pressing two incision inner membrane surfaces to be sutured, the inner membrane surfaces at two ends of an incision are matched, the pressing plates can be kept in a pressing state for a long time by matching of the arched supporting rods and the lock catch until tissue at an operation incision grows and heals into a whole, when the suturing effect is achieved, a suture line and a suture nail are not used, and the condition that blood leaks from a needle eye or a nail eye after the incision is sutured is avoided in the heart surgery operation.

The condition that the incision inner membrane surface is directly compressed by the compression plate and the conical protrusions is adopted, the length of an incision can be adjusted through the number of the surgical incision anastomosis pieces arranged side by side, the complex process of suture suturing is avoided, and the method is suitable for incision suturing operations with different lengths.

The cooperation of acting part and operation incision anastomosis spare is adopted, and the cephalic handle in the acting part inserts in the hem in the pressure strip outside, and this makes, after acting part drive pressure strip compresses tightly and accomplishes the locking, the separation that can and operation incision anastomosis spare of acting part, and the acting part need not remain in suture positions such as heart tissue.

Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

Example 1

It should be understood that, in this embodiment, the profile of the arch support is not necessarily a standard arch, i.e. the profile of the arch support is not necessarily a circular arc, as long as it is similar to the arch profile, and it is ensured that the two ends of the arch support are blocked by the elastic force when moving towards or away from each other.

It can be understood that, as shown in fig. 1, two lock pull rods are arranged in a staggered mode, two wedge-shaped surfaces of the wedge-shaped lock heads are arranged oppositely, and after the two pressing plates drive the end portions of the bow-shaped support rods to move oppositely to a certain degree, the two wedge-shaped lock heads can be buckled together to complete locking operation.

Example 2

Example 3

When the closing state is performed, the opposite surfaces of the lock catches 2 are touched to form a locking state. The operating forceps are also made into head handles 9 with different lengths according to the length of the operation incision anastomosis part.

Although the present disclosure has been described with reference to specific embodiments, it should be understood that the scope of the present disclosure is not limited thereto, and those skilled in the art will appreciate that various modifications and changes can be made without departing from the spirit and scope of the present disclosure.
