Description
Technical Field
The invention relates to a large wound blood vessel suturing device, and belongs to the technical field of medical instruments.
Background
With the development of medical science and technology, minimally invasive precision therapy is more and more concerned by more doctors and patients. Interventional therapy can minimize the actual trauma to non-focal areas of a patient while treating a targeted focal area. Is friendly to the overall treatment process and outcome, and therefore intervention is being required and accepted by an increasing number of patients. Interventional procedures are typically performed by puncturing a blood vessel to introduce a sheath and then advancing the catheter. Therefore, how to treat the wound caused by vascular puncture is a subject to be studied. In some operations requiring a large sheath and a large-diameter delivery system, such as an aortic stent, transcatheter aortic valve replacement and percutaneous mitral valve treatment, a blood vessel puncture wound is large (the outer diameter of the sheath is usually up to 21F, namely more than 7 mm), and how to close the blood vessel wound in a minimally invasive manner is a problem facing clinical practice at present.
The currently commonly used blood vessel suturing device is prolade (chinese patent No. CN1654016A) of yapei corporation, and the principle of the blood vessel suturing device is to form a suture line loop at a blood vessel wound through a puncture needle with a thread and tie and fix the suture line loop, although a large wound of the blood vessel can be sutured effectively, more than 2 suturing devices are usually needed to be used, and the operation is repeated more than twice, which causes complicated and difficult operation process. Secondly, the crossing angle between the suture lines formed by the two suturing devices needs to be controlled within a certain range, the too large angle easily causes stenosis, and the too small angle affects the suturing effect, so that a balance needs to be found between controlling the suturing effect and preventing restenosis, and the operator needs to have subjective experience and the capability of controlling operation errors.
Chinese patent No. CN210931590U discloses a large-caliber blood vessel interventional therapy suture device, which adopts a double-needle set to realize two times of suture by one-time operation so as to simplify the suture operation and achieve the effect of effective suture. According to the invention, two leading bases are arranged in a containing cavity body inserted into a vascular catheter side by side, an ellipsoidal dividing block is arranged between the two leading bases, the dividing block can rotate along the circumferential direction of the cross section of the catheter under the action of a driving device, so that the two leading bases are separated or closed to control the distance between the leading bases and control the distance between two suture lines, however, the arrangement of the dividing block and the driving device thereof can make the inserted vascular catheter become thicker, a larger left wound is left after suturing, and the suturing effect is influenced; the structure is too complex, so that the production and quality control of the instrument are troublesome and the performance of the instrument is unstable. In addition, because the center of the device is provided with the dividing block and the traditional system, the device is difficult to arrange a central lumen, so that the device is inserted into a vascular wound without a guide wire, the guide is difficult, and the guide wire cannot be reserved after the device is used for suturing the vascular wound, so that the device cannot intervene again if the suturing fails.
Chinese patent No. CN101897606A discloses another commonly used blood vessel suturing device (Angioseal) for hemostasis from the intravascular and extravascular clamping wounds by forming a sandwich structure using small spacers, but this device can only be applied to interventional procedures for small vessel wounds (below 8F).
Therefore, there is a need in the art to design a blood vessel suturing device that can conveniently and effectively suture a large blood vessel wound through one-time operation, and has a relatively simple structure, more stable performance and can suture after a suturing failure.

A large wound blood vessel suture device comprises a main body tube 1, an operating handle 2, a puncture needle 3, a suture 7, a bridge wire 4, a leading base 5 and a transmission mechanism 6 (shown in figure 1).
Main part pipe fitting 1 is the main part skeleton texture of whole device (like fig. 2), for the hard framework that macromolecular material or metal material made, for connecing leading base 5, pjncture needle 3, operating handle 2 to provide to support fixedly, main part pipe fitting 1 includes: the device comprises a main body pipe column 1-0, a conical guide pipe 1-1, a central guide cavity 1-2, a side lever 1-3, a guide pipeline 1-4, a base accommodating groove 1-5 and a plurality of pipe cavities 1-6. The main body of the middle section of the main body tubular column 1-0 is tubular, the cross section is circular or elliptical, the front end is a soft conical conduit 1-1, the function is to insert the whole suturing device into a vascular wound, the rear end is provided with two side rods 1-3, the side rods 1-3 are used for hooking the side rods 1-3 by fingers of both hands and operating the handle 2 for injection and suturing when the operation is convenient. The center of the main body pipe column 1-0 is provided with a central guide cavity 1-2, the front end of the central guide cavity is opened at the front port of the conical guide pipe 1-1, and the rear end of the central guide cavity is opened at the side of the main body pipe fitting 1. The blood guide channel 1-4 is a tiny pipeline positioned on the main body pipe fitting 1, the front end opening is positioned on the side surface of the main body pipe fitting 1 at the rear end of the base accommodating groove 1-5, the rear end opening is positioned on the side surface of the main body pipe fitting 1 close to the side lever 1-3 and used for indicating the insertion depth of the main body pipe fitting 1 into the blood vessel, when the blood flows in the blood guide channel 1-4, the front end opening of the blood guide channel 1-4 and the base accommodating groove 1-5 are prompted to enter the blood vessel cavity, the insertion depth of the whole suturing device into the blood vessel is enough, and subsequent operation can be carried out. The base accommodating grooves 1-5 are two hollow grooves formed in two sides of the front section of the main pipe fitting 1 and used for accommodating the connecting and leading base 5, so that the connecting and leading base 5 is stored in the connecting and leading base in a non-working state, and can extend out of the base accommodating grooves 1-5 in a working state. The main body pipe fitting 1 also comprises a plurality of tiny pipe cavities 1-6 for accommodating 4 puncture needles 3, 2 guide bases 5 and a transmission mechanism 6.
The operating handle 2 is in a front end cylindrical shape, a tail end round ball or an oval ball structure which is positioned at the rear end of the main body pipe fitting 1 and is detachably connected with the main body pipe fitting 1, and the front end of the operating handle is connected with four puncture needles 3. In operation, by pushing the operating handle 2 forward so that it is entirely close to the main body tube 1 to push the puncture needle 3, a sufficient forward force is generated to the puncture needle to penetrate the blood vessel and abut against the introduction hole 5-12 of the introduction base 5 to finally form a suture circuit.
The puncture needle 3 is a straight metal thin needle, and the rear end is connected with the operating handle 2. The puncture needles 3 respectively run in the pipelines of the tiny lumens 1-6 of the main body pipe fitting 1, can move back and forth along the pipelines and cannot shake. The rear end of the fine pipeline is opened at the rear end of the main body pipe fitting 1, the front end of the fine pipeline is opened at the side hole at the rear end of the leading base 5 of the main body pipe fitting 1, the puncture needle 3 is pushed forwards, the puncture needle 3 extends out along the side hole (namely a guide mechanism) at the front end of the fine pipeline and accurately reaches the leading holes 5-12 of the leading base 5, and the connection of the suture line 7 and the bridging line 4 is realized. The puncture needles 3 are provided with two groups, one group comprises a puncture needle 3-1 with suture and a puncture needle 3-2 without suture. The sewing thread 7 is a high polymer material thread. In the puncture needle 3-1 with suture, the front end of the suture is connected with a short stick needle 7-1, the stick needle 7-1 comprises a pointed cone at the front end and a suture sleeve 7-2 at the rear end; the front end of the needle is a pointed cone, and the rear end of the pointed cone is provided with a suture sleeve 7-2. The pointed cone can puncture the blood vessel and is inserted into the sleeve I4-1 of the bridgewire 4 to realize the connection of the suture 7 and the bridgewire 4. The suture sleeve 7-2 is detachably connected with the puncture needle 3-1, when the suture 7 is connected with the bridge wire 4 through the pointed cone, the suture sleeve 7-2 is separated from the puncture needle 3-1, and the suture 7 is also separated from the puncture needle 3-1 but connected with the bridge wire 4, because the connecting force between the suture 7 and the bridge wire 4 is far larger than that between the suture sleeve 7-2 and the puncture needle 3-1. The puncture needle 3-2 without suture is provided with a pointed cone at the front end, and the pointed cone can be connected with the sleeve II 4-2 at the other end of the bridge wire 4, so that the bridge wire 4 is firmly connected to the puncture needle 3-2. The two ends of the bridge wire 4 are provided with a sleeve I4-1 and a sleeve II 4-2, and the middle part of the bridge wire 4-3 made of high polymer material is arranged in the middle. The front end of the suture 7 is connected with a puncture needle 3-1 through a short stick needle 7-1, and the suture at the far end is preset with a fisherman knot 7-21 and is wrapped on the puncture needle 3-2 without the suture. The above structure design of the puncture needle 3, the suture 7 and the bridge wire 4 enables the suture 7 to automatically form a loop knot suture wound after the puncture needle 3 punctures into a blood vessel and exits from the blood vessel, as shown in fig. 4: the puncture needle 3-1 with the suture line connects the suture line 7 with the bridge thread 4 through the short stick needle 7-1 and then is separated from the suture line loop, the puncture needle 3-2 without the suture line is connected with the bridge thread 4 through the sleeve II 4-2, after the puncture needle 3 integrally exits from the main body pipe fitting 1, the bridge thread 4 is pulled out of the blood vessel by the puncture needle 3-2 without the suture line, and the suture line is pulled into the blood vessel to form a loop, meanwhile, as the fisher knot 7-21 at the far end of the suture line is wrapped on the puncture needle 3-2 without the suture line, the puncture needle 3-2 without the suture line takes the bridge thread 4 to penetrate out from the center of the fisher knot 7-21, so that the coil enters from one puncture needle port and penetrates out from the other puncture port and automatically forms a thread knot outside the blood vessel, and the knot can be knotted by tensioning.
The connecting and guiding base 5 comprises a connecting and guiding base part 5-2, a rotating shaft 5-3 and wing parts 5-1 arranged on two sides of the connecting and guiding base part 5-2. The connecting and leading base 5 is arranged in a base accommodating groove 1-5 of the main body pipe fitting 1 and is connected with the main body pipe fitting 1 through a rotating shaft 5-2, the connecting and leading base 5 is rotated to about 90 degrees, so that the side wing part 5-1 can simultaneously extend out of an opening of the accommodating groove 1-5, and the connecting and leading base 5 and the main body pipe fitting 1 are in a cross state. The rotation is driven by a transmission mechanism 6 provided in the main body tube 1. The two side wing parts 5-1 of the guide base 5 are both provided with guide holes 5-12, and the guide holes 5-12 penetrate through the two side wing parts 5-1. Two sleeves 4-1 and 4-2 of a bridging line 4 are detachably arranged in the connecting and leading holes 5-12, the bridging line passes through the two connecting and leading holes 5-12, and a middle section 4-3 of the bridging line is arranged in a conical conduit 1-1 at the front end of the connecting and leading base 5. The two lead bases 5 are respectively arranged in the two base accommodating grooves 1-5 and provide fixing force for the connection of the two groups of puncture needles and the two lines.
