Description

Technical Field

[0001] The present invention relates to the technical field of vascular clamping, and particularly relates to a non-invasive vascular clamping device for thoracoscopic surgery and an operation method thereof. Background Art

[0002] Thoracoscopic surgery uses modern imaging technology and high-tech surgical instruments and equipment to complete complex intrathoracic surgeries through chest wall trocars or small incisions, belonging to a new minimally invasive thoracic surgery technology. Generally, only 1 to 3 small 1.5-cm chest wall holes need to be made for this kind of surgery, and the situation inside the chest cavity can be projected onto a large display screen through a small medical camera, thus completing the surgery. The non-invasive vascular clamping device plays a crucial role in thoracoscopic surgery. The vascular clamping device usually consists of a vascular clamp forceps and a vascular clip. Classified by the usage method, the vascular clip can be divided into single-type and continuous-type. Classified by the structure, it can be divided into ordinary vascular clips and buckle vascular clips. The buckle vascular clip has a buckling device, with complete clamping and no slippage. Most are made of plastic materials and are a product gradually replacing traditional metal titanium clips. Its biocompatibility is better than that of metal titanium clips, and it uses a specially matched clip applicator forceps with a better feel. The vascular clip can be divided into three categories according to the material: titanium clips, medical polymer clips, and absorbable bio-clips. When using a vascular clip to clamp a vascular rupture, it is necessary to first place the vascular clip in the two jaws of the vascular clip forceps, and then use the two jaws of the vascular clip forceps to clamp and fix the vascular clip at the rupture of the blood vessel. However, when the traditional vascular clamping device is in use, the stability of the vascular clip placed in the two jaws of the vascular clip forceps is poor, and during the movement, the vascular clip is likely to fall off from the two jaws of the vascular clip forceps. Therefore, it is often necessary to repeatedly place the vascular clip into the two jaws of the vascular clip forceps, which will affect the efficiency of vascular ligation and ultimately affect the surgical efficiency. Moreover, the stability of the traditional vascular clip for clamping blood vessels needs to be improved, which will bring a relatively high surgical risk to the patient. Therefore, a non-invasive vascular clamping device for thoracoscopic surgery is needed to solve the above problems. Summary of the Invention

[0003] The main purpose of the present invention is to provide a non-invasive vascular clamping device for thoracoscopic surgery and an operation method thereof, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows: Non-invasive vascular clamping device for thoracoscopic surgery, including a vascular clamp component, on which two clamp jaws are symmetrically installed. The clamp jaws are composed of a connecting frame and an arc-shaped clamping plate. The arc-shaped clamping plate is fixedly installed at one end of the connecting frame. A first vascular clamp is installed at the inner end of one of the clamp jaws. The first vascular clamp is composed of a first clamping plate and a first clamping rod. There are several first clamping rods, all of which are fixedly installed at the inner end of the first clamping plate. A second vascular clamp is installed at the inner end of the other clamp jaw. The second vascular clamp is composed of a second clamping plate and a second clamping rod. There are several second clamping rods, all of which are fixedly installed at the inner end of the second clamping plate. The first vascular clamp and the second vascular clamp are both installed on the clamp jaws through several connecting buckles. The connecting buckle is composed of a base plate, an arc-shaped insertion plate, and an arc-shaped strip. There are four arc-shaped insertion plates, symmetrically and fixedly installed at one end of the base plate. There are four arc-shaped strips, respectively fixedly installed on the outer walls of the four arc-shaped insertion plates. Two fixing components are symmetrically and fixedly installed at the inner end of the second clamping plate. The fixing component is composed of a fixing block, an anti-disengagement plate, a base rod, a spring, a moving block, and a clamping block. The anti-disengagement plate is slidably installed in the fixing block. The base rod is fixedly installed at one end of the anti-disengagement plate. The spring is sleeved on the base rod. The moving block is fixedly installed at one end of the base rod, and both the moving block and the spring are located on one side of the fixing block. The clamping block is fixedly installed on the outer wall of the moving block.

[0005] Preferably, the vascular clamp component is composed of a connecting pipe, a connecting rod, and a connecting plate. The connecting rod and the connecting plate are both movably installed in the connecting pipe. There are two connecting plates, both of which are rotatably connected to the connecting rod through a pin shaft.

[0006] Preferably, the two connecting frames on the two clamp jaws are rotatably connected by a pin shaft and a connecting pipe. The connecting frame and the pin shaft for connecting the two connecting frames are both slidably installed in the connecting pipe, and the connecting frame is also rotatably installed on the connecting plate through a pin shaft.

[0007] Preferably, several mounting blind holes are opened at the inner end of the arc-shaped clamping plate on the clamp jaw, and an annular clamping groove is opened on the inner wall of the mounting blind hole.

[0008] Preferably, two through holes are symmetrically opened on the first clamping plate of the first vascular clamp. The through holes penetrate the first clamping plate inside and outside. A fixing clamping groove is opened on the inner wall of the through hole, and several first clamping grooves are evenly opened at the inner end of the first clamping plate.

[0009] Preferably, several second clamping grooves are evenly opened at the inner end of the second clamping plate of the second vascular clamp.

[0010] Preferably, the substrate and the arc-shaped insertion plate on the connecting buckle are both inserted into the installation blind holes formed at the inner ends of the arc-shaped clamping plates. The arc-shaped strip is clamped in the annular clamping groove formed on the inner wall of the installation blind hole, and the substrate is fixedly connected to the outer ends of the first clamping plate or the second clamping plate.

[0011] Preferably, the fixing block on the fixing component is fixedly installed at the inner end of the second clamping plate. An anti-detachment groove is formed in the fixing block, and a through hole is formed at the inner end of the fixing block. The through hole communicates with the anti-detachment groove.

[0012] Preferably, the anti-detachment plate on the fixing component is slidably installed in the anti-detachment groove. The base rod passes through the through hole, and the base rod can slide in the through hole.

[0013] The using method of the non-invasive blood vessel clamping device for thoracoscopic surgery includes the following steps: S1: During use, the first blood vessel clip and the second blood vessel clip need to be fixedly installed at the inner ends of the two arc-shaped clamping plates on the two clamping jaws of the clamp through the connecting buckle, that is, the substrate and the arc-shaped insertion plate on the connecting buckle are inserted into the installation blind holes formed at the inner ends of the arc-shaped clamping plates, and the arc-shaped strip is clamped in the annular clamping groove formed on the inner wall of the installation blind hole. At this time, the first clamping plate on the first blood vessel clip and the second clamping plate on the second blood vessel clip will respectively contact the inner ends of the two arc-shaped clamping plates on the two clamping jaws. S2: Then, the first blood vessel clip and the second blood vessel clip can be clamped at the break of the blood vessel through the blood vessel clip component, so as to ligate the break of the blood vessel. Before that, the blood vessel clip component needs to be connected to the handle of the blood vessel clamp, so that the operator can operate the clamping jaws through the handle and the blood vessel clip component. Then, the operator can put the blood vessel clip component and the clamping jaws into the patient's body, so that the two clamping jaws are respectively located on both sides of the blood vessel break. Then, the operator can pull the connecting rod in the connecting pipe through the handle, and the connecting rod will drive the clamping jaws to move through the connecting plate. Furthermore, the two arc-shaped clamping plates on the two clamping jaws will approach and clamp each other, and finally the first blood vessel clip and the second blood vessel clip are clamped at the break of the blood vessel. S3: When the first blood vessel clip and the second blood vessel clip are clamped at the break of the blood vessel, it is necessary to make the first clamping plate and the second clamping plate approach and clamp the blood vessel tissue. At the same time, make the first clamping rod push part of the blood vessel tissue to be stuck in the second clamping groove, make the second clamping rod push part of the blood vessel tissue to be stuck in the first clamping groove, and make the fixing component be stuck in the through hole and the fixing clamping groove. S4: When the fixing assembly enters the through hole, the anti-drop plate, base rod, movable block and clamping block are first limited by the through hole and move toward the fixed block. At this time, the spring is compressed by the movable block and the fixed block. When the fixing assembly is completely entered into the through hole and the clamping block is aligned with the fixed clamping slot, the clamping block is clamped in the fixed clamping slot under the elastic force of the spring. At this time, the first vascular clamp and the second vascular clamp are clamped at the rupture of the blood vessel. S5: Finally, the connecting rod is pushed by the handle to move in the connecting tube, thereby separating the two clamp jaws through the connecting plate. At this time, since the first vascular clamp and the second vascular clamp are clamped and fixed on the blood vessel by the fixing assembly, as the two clamp jaws are separated, the connecting buckle will be squeezed and deformed, and slowly moved out of the mounting blind hole and the annular groove. Finally, when the connecting buckle is completely moved out of the arc-shaped clamp plate, the first vascular clamp and the second vascular clamp will be left on the patient's blood vessel.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) By providing a vascular clamp consisting of a first vascular clamp and a second vascular clamp, the first clamping rod and the first clamping groove on the first vascular clamp and the second vascular clamp cooperate with the second clamping rod and the second clamping groove, which can achieve a better ligation effect on the vascular rupture, thereby making the vascular clamp more stable in clamping the blood vessel, thereby reducing the surgical risk of the patient; (2) By providing a clamp jaw consisting of a connecting frame and an arc-shaped splint, and providing a connecting buckle on the first vascular clamp and the second vascular clamp, the first vascular clamp and the second vascular clamp can be connected to the clamp jaw with better stability, so that when the first vascular clamp and the second vascular clamp are installed on the clamp jaw and moved, the first vascular clamp and the second vascular clamp are not likely to fall off from the clamp jaw, thereby ensuring the efficiency of ligation of the vascular rupture and the operation; (3) By setting up a fixing component, the connection between the first vascular clamp and the second vascular clamp can be made more stable, making it difficult for the first vascular clamp and the second vascular clamp to separate, thereby making it difficult for the first vascular clamp and the second vascular clamp to fall off the blood vessel, thereby further improving the effect of the vascular clamp composed of the first vascular clamp and the second vascular clamp on ligating the vascular rupture.

Embodiment 2:

[0024] As Figure 1-10As shown, the method of using a non-invasive vascular clamping device for thoracoscopic surgery includes the following steps: S1: During use, the first vascular clip 3 and the second vascular clip 4 need to be fixedly installed at the inner ends of two arc-shaped clamping plates 11 on two clamping jaws 2 of the clamp respectively through connecting buckles 5, that is, the base plate 30 and the arc-shaped insertion plate 31 on the connecting buckle 5 are inserted into the installation blind holes 12 opened at the inner ends of the arc-shaped clamping plates 11, so that the arc-shaped strip 32 is clamped in the annular clamping groove 13 opened on the inner wall of the installation blind hole 12.

Finally, when the connecting buckle 5 completely moves out of the arc-shaped clamping plate 11, the first vascular clamp 3 and the second vascular clamp 4 are left on the patient's blood vessel.

The using method of a non-invasive vascular clamping device for thoracoscopic surgery, characterized in that: It includes the following steps: S1: During use, the first blood vessel clip (3) and the second blood vessel clip (4) need to be fixedly installed at the inner ends of the two arc-shaped clamping plates (11) on the two clamping jaws (2) of the blood vessel clip through the connecting buckle (5), that is, the base plate (30) and the arc-shaped insertion plate (31) on the connecting buckle (5) are inserted into the mounting blind hole (12) formed at the inner end of the arc-shaped clamping plate (11), and the arc-shaped strip (32) is clamped in the annular card slot (13) formed on the inner wall of the mounting blind hole (12). At this time, the first clamping plate (14) on the first blood vessel clip (3) and the second clamping plate (19) on the second blood vessel clip (4) will respectively contact the inner ends of the two arc-shaped clamping plates (11) on the two clamping jaws (2). S2: Then, the first blood vessel clip (3) and the second blood vessel clip (4) can be clamped at the break of the blood vessel by the blood vessel clip assembly (1), so as to ligate the break of the blood vessel. Before that, the blood vessel clip assembly (1) needs to be connected to the handle of the blood vessel clip, so that the operator can operate the clamping jaws (2) through the handle and the blood vessel clip assembly (1). Then, the operator can place the blood vessel clip assembly (1) and the clamping jaws (2) into the patient's body, so that the two clamping jaws (2) are respectively located on both sides of the blood vessel break. Then, the operator can pull the connecting rod (8) in the connecting pipe (7) through the handle, and the connecting rod (8) will drive the clamping jaws (2) to move through the connecting plate (9). Further, the two arc-shaped clamping plates (11) on the two clamping jaws (2) will approach and clamp each other, and finally, the first blood vessel clip (3) and the second blood vessel clip (4) are clamped at the break of the blood vessel. S3: When clamping the first vascular clamp (3) and the second vascular clamp (4) at the break of the blood vessel, it is necessary to make the first splint (14) and the second splint (19) close to clamp the vascular tissue. At the same time, make the first clamping rod (15) push part of the vascular tissue to be stuck in the second card slot (21), make the second clamping rod (20) push part of the vascular tissue to be stuck in the first card slot (16), and make the fixing component (6) be stuck in the through hole (17) and the fixing card slot (18); S4: When the fixing component (6) enters the through hole (17), the anti - detachment plate (25), the base rod (26), the moving block (28) and the clamping block (29) will first be limited by the through hole (17) and move towards the fixing block (22). At this time, the spring (27) will be compressed by the moving block (28) and the fixing block (22). When the fixing component (6) completely enters the through hole (17) and the clamping block (29) is aligned with the fixing card slot (18), under the elastic force of the spring (27), the clamping block (29) will be stuck in the fixing card slot (18). At this time, the first vascular clamp (3) and the second vascular clamp (4) are clamped at the break of the blood vessel; S5: Finally, push the connecting rod (8) to move in the connecting pipe (7) through the handle, so as to separate the two clamp jaws (2) through the connecting plate (9). At this time, since the first vascular clamp (3) and the second vascular clamp (4) are clamped and fixed on the blood vessel through the fixing component (6), therefore, as the two clamp jaws (2) are separated, the connecting buckle (5) will be squeezed and deformed and slowly move out of the installation blind hole (12) and the annular card slot (13). Finally, when the connecting buckle (5) completely moves out of the arc - shaped splint (11), the first vascular clamp (3) and the second vascular clamp (4) are left on the patient's blood vessel.
