DETAILED DESCRIPTION
[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.
[0032] See also Figure 1-Figure 4 , which is a schematic structural diagram of the disposable V-shaped blood blocking clip provided by the utility model.
[0033] As can be seen from the figure, the disposable V-shaped blood blocking clip provided by the utility model includes three components: a first clip 100, a second clip 200, and an elastic member 300.
[0034] The disposable V-shaped blood blocking clip provided by the utility model is used for clamping blood vessels in surgical operations to prevent blood from flowing out of the disconnected blood vessels.
[0035] The first clamp 100 and the second clamp 200 have the same structure and are both V-shaped. The first clamp handle 400 and the second clamp handle 500 are connected to one end of the V-shape of the first clamp 100 and the second clamp handle 500 respectively. The first clamp handle 400 and the second clamp handle 500 are connected by a movable connecting member 600, so that the first V-shaped ends of the first clamp 100 and the second clamp 200 respectively form a first V-shaped clamping groove 110 and a second V-shaped clamping groove 210 for clamping a blood vessel.
[0036] The elastic member 300 is disposed between the first clamping handle 400 and the second clamping handle 500 so that the first clamping piece 100 and the second clamping piece 200 have a clamping force;
[0037] The V-shaped surfaces at both ends of the first clamp 100 and the second clamp 200 are respectively provided with mutually offset first clamping teeth 700 and second clamping teeth 800. The elastic clamping force of the elastic member 300 enables the first clamping teeth 700 and the second clamping teeth 800 to be offset and engaged.
[0038] In this solution, a V-shaped first clamp 100 and a second clamp 200 are used. The V-shaped structure can not only provide a better operation field of view for the doctor, but also the two V-shaped first clamps 100 and the second clamps 200 can form a first V-shaped clamping groove 110 and a second V-shaped clamping groove 210, so that two parts of the blood vessel can be clamped at the same time, and two parts of the same blood vessel can be clamped at the same time to block blood flow, which can replace two ordinary hemostatic clips or conventional double clamps in the prior art, reduce the operation time for the doctor, and prevent blood vessel dislocation;
[0039] Furthermore, in the present solution, since the first clamp 100 and the second clamp 200 are of the same V-shaped structure, one end of each of them generates an elastic clamping force through the elastic member 300, so that the clamping force of the first V-shaped clamping groove 110 and the second V-shaped clamping groove 210 is the same, and in coordination with this, the first clamping tooth portion 700 and the second clamping tooth portion 800 are offset from each other, and the two cooperate to form an offset bite, so as to ensure that blood flow can be blocked without damaging the blood vessel wall.
[0040] like Figure 2In actual application, by applying force to the first clamp handle 400 and the second clamp handle 500, the first clamp 100 and the second clamp 200 can rotate around the movable connecting member 600 at a certain angle, so that the first V-shaped clamping groove 110 and the second V-shaped clamping groove 210 are opened to form a corresponding angle, and the blood blocking clamp is in an open state at this time;
[0041] like Figure 3 When the force on the first clamp handle 400 and the second clamp handle 500 is released, the first V-shaped clamp groove 110 and the second V-shaped clamp groove 210 will be closed under the force of the rigid rebound of the elastic member 300, and the blood blocking clamp is in a closed state at this time. It can clamp the blood vessel 10 and form a first clamping point 111 and a second clamping point 211 respectively;
[0042] like Figure 6 By moving the blood vessel 10 along the length direction of the first V-shaped clamping groove 110 and the second V-shaped clamping groove 210, the straight-line distance between the first clamping point 111 and the second clamping point 211 can be lengthened or shortened.
[0043] like Figure 6 In this way, the doctor can move the blood vessel 10 to be operated on in the ab direction according to the needs, so as to adjust the operation distance C of the blood vessel 10 to be operated on.
[0044] In some embodiments of the present invention, Figure 4 , Figure 5 , the first clamping tooth portion 700 and the second clamping tooth portion 800 are both composed of a plurality of clamping teeth 710 , and the plurality of clamping teeth 710 in the first clamping tooth portion 700 and the plurality of clamping teeth 710 in the second clamping tooth portion 800 are staggered and do not contact each other;
[0045] In this way, after the first clamping tooth portion 700 and the second clamping tooth portion 800 are closed, the clamping teeth 710 in the first clamping tooth portion 700 and the clamping teeth 710 in the second clamping tooth portion 800 are interlaced and engaged with each other without contacting each other.
[0046] On this basis, in order to further protect the clamped blood vessel 10, as Figure 5 The clamping teeth 710 are conical clamping teeth, and the surface of the clamping teeth 710 is arc-shaped and has no edges or corners, so that the blood vessel tissue can be effectively protected.
[0047] In some embodiments of the present invention, the first clamping handle 400 and the second clamping handle 500 have the same structure, and are preferably in a square box shape. Figure 1 The first clamping handle 400 and the second clamping handle 500 are symmetrically arranged, and both sides of the first clamping handle 400 extend outward to form symmetrical first connecting lugs 420, and both sides of the second clamping handle 500 extend outward to form second connecting lugs 520 corresponding to the first connecting lugs 420;
[0048] The first connecting lug 420 and the second connecting lug 520 are offset inside and outside, and are respectively provided with corresponding through holes 430. The movable connecting member 600 passes through the through holes 430 of the first connecting lug 420 and the second connecting lug 520 in sequence and is fixed to movably connect the first clamping handle 400 and the second clamping handle 500.
[0049] Furthermore, the present solution does not limit the structure of the movable connecting member 600, which can be determined according to actual needs, as long as the first clamp 100 and the second clamp 200 can stably rotate relative to each other without falling off. For example, the movable connecting member 600 is preferably made of a stainless steel tube, and the two ends of the stainless steel tube are riveted and flanging to achieve anti-detachment with the first clamp handle 400 and the second clamp handle 500.
[0050] like Figure 7 ,like Figure 8 The first clamping handle 400 and the second clamping handle 500 of such a structure cooperate with the elastic member 300. The first clamping handle 400 and the second clamping handle 500 are respectively provided with a first groove 410 and a second groove 510 on the opposite contact surfaces for fixing the elastic member 300.
[0051] In conjunction with it, Figure 1 The elastic member 300 is V-shaped and includes a first elastic piece 310 and a second elastic piece 320 . The first elastic piece 310 and the second elastic piece 320 are respectively installed in the first groove 410 and the second groove 510 , and the first elastic piece 310 and the second elastic piece 320 are connected to each other at one end close to the first clip 100 and the second clip 200 .
[0052] The clamping force of the entire blood-blocking clamp comes from the elastic member 300. The elastic member 300 is preferably made of a stainless steel sheet. The elastic member 300 is formed by bending the stainless steel sheet into an angle that meets the required clamping force. Its two ends are respectively against the first groove 410 and the second groove 510. At this time, the bending angle of the elastic member 300 is always in a compressed state, and under the tension rebound force of the spring sheet, the upper and lower clamps are prompted to bite each other.
[0053] In order to further improve the reliability of the blood clamp, Fig. 9 The outward surfaces of the first clamping handle 400 and the second clamping handle 500 are both provided with arc-shaped anti-skid grooves 440, and an anti-skid convex ridge 450 is provided at one end of the arc-shaped anti-skid groove 440 close to the first clamping piece 100 or the second clamping piece 200;
[0054] The arc-shaped anti-skid groove 440 and the anti-skid ridge 450 play an anti-skid role, which is convenient for doctors to operate manually. By pressing the two arc-shaped anti-skid grooves 440 by hand, the blood blocking clamp is opened, and after releasing the hand, the blood blocking clamp is clamped.
[0055] Furthermore, the first clamp block 101 and the second clamp block 102 are respectively provided at the two ends of the V-shape of the first clamp 100 and the second clamp 200, and the first clamp block 101 and the second clamp block 102 are arranged in parallel, and the first clamp block 101 and the second clamp block 102 are respectively connected to the two ends of the V-shape of the first clamp 100 and the second clamp 200 with an arc transition. When the V-shaped blood-blocking clamp is required to perform maximum vascular surgery, the turning design of the first clamp block 101 and the second clamp block 102 here is beneficial to prevent blood vessel slippage.
[0056] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
