DETAILED DESCRIPTION

[0038] 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.

[0039] See also Figure 1-Figure 3 , which is a schematic structural diagram of a disposable V-shaped blood blocking clamp with a frame provided by the utility model.

[0040] As can be seen from the figure, the disposable V-shaped blood blocking clamp with frame provided by the utility model includes three components: a blood blocking clamp body 100, a support frame assembly 200, and a connecting shaft 300.

[0041] The disposable V-shaped blood vessel blood blocker with frame provided by the utility model is used for clamping the blood vessel 10 in surgical operations. The tissue around the blood vessel 10 is auxiliary supported by the support frame assembly 200 so that the blood blocker body 100 can clamp the blood vessel 10 to prevent blood from flowing out of the disconnected blood vessel 10.

[0042] The blood blocking clip body 100 includes a first clip 110, a second clip 120, and an elastic member 130;

[0043] The first clamping piece 110 and the second clamping piece 120 have the same structure and are both V-shaped. One end of the V-shaped portion of the first clamping piece 110 and the second clamping piece 120 is connected to a first clamping handle 140 and a second clamping handle 150 respectively.

[0044] The first clamp handle 140 and the second clamp handle 150 are arranged opposite to each other and are movably connected through a connecting shaft 300. The connecting shaft 300 passes through the first clamp handle 140 and the second clamp handle 150 and both ends are connected to the supporting frame assembly 200 respectively, so as to assemble the blood blocking clamp body 100 and the supporting frame assembly 200.

[0045] The blood blocking clip body 100 is integrally placed in the support frame assembly 200, and the support frame assembly 200 is used to provide auxiliary support for the tissue around the blood vessel 10;

[0046] The elastic member 130 is disposed between the first clamp handle 140 and the second clamp handle 150 so that the first clamp 110 and the second clamp 120 have a clamping force. The V-shaped ends of the first clamp 110 and the second clamp 120 respectively form a first V-shaped clamping groove 160 and a second V-shaped clamping groove 170 for clamping the blood vessel 10.

[0047] In actual application, after the scalpel cuts the skin tissue, the incision will be pulled open by the hook forceps to a certain operating space, and the entire framed V-shaped vascular blocking clamp will clamp the blood vessel that needs surgery to block blood flow. The support frame assembly 200 can assist in opening the cut tissue under the force of its own structural strength;

[0048] In this solution, the support frame assembly 200 is used to support the tissue around the blood vessel 10, which can solve the problem in the prior art that other tissues around the blood vessel block the blood vessel, making it impossible for the blood clamp to clamp the blood vessel;

[0049] Furthermore, the present solution adopts a V-shaped first clamp 110 and a second clamp 120. 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 110 and the second clamps 120 can form a first V-shaped clamping groove 160 and a second V-shaped clamping groove 170, 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 the two ordinary hemostatic clips or conventional double clamps in the prior art, reduce the operation time for the doctor, and prevent the dislocation of the blood vessel;

[0050] like Figure 3 In actual application, by applying force to the first clamp handle 140 and the second clamp handle 150, the first clamp handle 140 and the second clamp handle 150 can resist the elastic force of the elastic member 130 and approach each other, and the first clamp handle 140 and the second clamp handle 150 drive the first clip 110 and the second clip 120 to move away from each other, so that the first V-shaped clamping groove 160 and the second V-shaped clamping groove 170 at both ends of the V-shape of the first clip 110 and the second clip 120 are opened, and the opening and closing size of the first V-shaped clamping groove 160 and the second V-shaped clamping groove 170 is based on the size of the applied force, and the blood blocking clamp is in an open state at this time;

[0051] like Figure 2 When the force on the first clamp handle 140 and the second clamp handle 150 is released, the first V-shaped clamping groove 160 and the second V-shaped clamping groove 170 will be closed under the force of the rigid rebound of the elastic member 130. At this time, the blood blocking clamp is in a closed state, and can clamp the blood vessel 10 and form a first clamping point 111 and a second clamping point 121 respectively;

[0052] like Figure 6 By moving the blood vessel 10 along the length direction of the first V-shaped clamping groove 160 and the second V-shaped clamping groove 170, the straight-line distance between the first clamping point 111 and the second clamping point 121 can be lengthened or shortened.

[0053] 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.

[0054] Furthermore, in order to further improve the effect and reliability of the blood blocking clip, as Figure 4 The first clamping piece 110 and the second clamping piece 120 are respectively provided with a first clamping tooth portion 410 and a second clamping tooth portion 420 which are offset from each other on the inward surfaces at both ends of the V-shape. The first clamping tooth portion 410 and the second clamping tooth portion 420 can be offset and engaged with each other through the elastic pressing force of the elastic member 130.

[0055] In some embodiments of the present invention, Figure 4 , Figure 5The first clamping tooth portion 410 and the second clamping tooth portion 420 are both composed of a plurality of clamping teeth 411, and the plurality of clamping teeth 411 in the first clamping tooth portion 410 and the plurality of clamping teeth 411 in the second clamping tooth portion 420 are staggered and do not contact each other;

[0056] In this way, after the first clamping tooth portion 410 and the second clamping tooth portion 420 are closed, the clamping teeth 411 in the first clamping tooth portion 410 and the clamping teeth 411 in the second clamping tooth portion 420 are interlaced and engaged with each other without contacting each other.

[0057] On this basis, in order to further protect the clamped blood vessel 10, as Figure 5 The clamping teeth 411 are conical clamping teeth, and the surface of the clamping teeth 411 is arc-shaped and has no edges or corners, so that the blood vessel tissue can be effectively protected.

[0058] Furthermore, in the present solution, since the first clamp 110 and the second clamp 120 are of the same V-shaped structure, one end of each of which generates an elastic clamping force through the elastic member 130, the clamping force of the first V-shaped clamping groove 160 and the second V-shaped clamping groove 170 is the same, and in coordination with this, by using the first clamping tooth portion 410 and the second clamping tooth portion 420 that are offset from each other, the two cooperate to form an offset bite, thereby ensuring that blood flow can be blocked without damaging the blood vessel wall.

[0059] Specifically, the inner wall space of the support frame assembly 200 in this solution is larger than the blood blocking clip body 100, and the support frame assembly 200 can entirely contain the blood blocking clip body 100;

[0060] like Figure 7 The support frame assembly 200 adopts a split structure, which includes a first frame portion 210 and a second frame portion 220. The first frame portion 210 and the second frame portion 220 have the same structure and are both C-shaped. Both ends of the first frame portion 210 are respectively provided with connecting holes 211, and both ends of the second frame 220 are respectively provided with connecting pieces 221 corresponding to the connecting holes 211. The first frame portion 210 and the second frame portion 220 are assembled by connecting the connecting pieces 221 with the connecting holes 211.

[0061] The middle parts of the first frame portion 210 and the second frame 220 extend outward to form a first connecting lug 212 , and the first connecting lug 212 is provided with a first through hole 212 a for matching and connecting with the connecting shaft 300 .

[0062] The present solution does not limit the connection method between the connector 221 and the connecting hole 211. As an example, in this embodiment, it is preferred to insert the connector 221 into the connecting hole 211 and then use hot-melt welding to prevent it from falling off, thereby further improving the connection reliability.

[0063] The support frame assembly 200 of such a structure is connected with the first clamp handle 140 and the second clamp handle 150 in the hemostatic clip body 100 through the connecting shaft 300, thereby realizing the assembly of the support frame assembly 200 and the hemostatic clip body 100.

[0064] The first clamping handle 140 and the second clamping handle 150 have the same structure, and are preferably in a square box shape. Figure 1 The first clamping handle 140 and the second clamping handle 150 are symmetrically arranged, and both sides of the first clamping handle 140 extend outward to form symmetrical second connecting lugs 141, and both sides of the second clamping handle 150 extend outward to form third connecting lugs 151 corresponding to the second connecting lugs 141;

[0065] The second connecting lug 141 and the third connecting lug 151 are staggered inside and outside. The second connecting lug 141 is provided with a second through hole 141a. The third connecting lug 151 is provided with a third through hole 151a. The second through hole 141a and the third through hole 151a are on the same axis.

[0066] In coordination therewith, the connecting shaft 300 is inserted into the first through hole 212a, the second through hole 141a, and the third through hole 151a. The cross section of the connecting shaft 300 is in a D shape. The first through hole 212a and the third through hole 151a are D-shaped holes adapted to the cross section of the connecting shaft 300. The second through hole 141a is a circular hole having a diameter larger than the cross section of the connecting shaft 300.

[0067] By adopting the above technical solution, since the cross-section of the connecting shaft 300 and the first through hole 212a and the third through hole 151a are all D-shaped, the second clamping handle 150, the first frame portion 210 and the second frame portion 220 can rotate synchronously, that is, they cannot rotate relative to the connecting shaft 300; since the diameter of the second through hole 141a is a circular hole larger than the cross-section of the connecting shaft 300, the first clamping handle 140 can rotate along the connecting shaft 300.

[0068] In this example, the two ends of the connecting shaft 300 are preferably riveted and flanged to limit the axial movement of the first frame 210 and the second frame 220 relative to the connecting shaft 300 to achieve anti-slip; and preferably, two grooves are provided on the connecting shaft 300 corresponding to the positions of the second connecting lug 141 and the third connecting lug 151, and the grooves can accommodate retaining springs to be placed therein. A limiting space is formed between the two retaining springs, and the second connecting lug 141 and the third connecting lug 151 can be confined in the limiting space to limit the axial movement of the above-mentioned first clamping handle 140 and the second clamping handle 150 along the connecting shaft 300.

[0069] like Figure 8 ,like Fig. 9The first clamping handle 140 and the second clamping handle 150 of such a structure cooperate with the elastic member 130 , and the first clamping handle 140 and the second clamping handle 150 are respectively provided with a first groove 142 and a second groove 152 on the opposite contact surfaces for fixing the elastic member 130 .

[0070] In conjunction with it, Figure 1 The elastic member 130 is V-shaped and includes a first elastic piece 131 and a second elastic piece 132 . The first elastic piece 131 and the second elastic piece 132 are respectively disposed in the first groove 142 and the second groove 152 , and the first elastic piece 131 and the second elastic piece 132 are connected to one end close to the first clip 110 and the second clip 120 .

[0071] The clamping force of the entire blood-blocking clamp comes from the elastic member 130. The elastic member 130 is preferably made of a stainless steel sheet. The elastic member 130 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 142 and the second groove 152. At this time, the bending angle of the elastic member 130 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.

[0072] In order to further improve the reliability of the blood blocking clip, Fig.10 The outward surfaces of the first clamping handle 140 and the second clamping handle 150 are both provided with arc-shaped anti-skid grooves 143, and an anti-skid convex ridge 144 is provided at one end of the arc-shaped anti-skid groove 143 close to the first clamping piece 110 or the second clamping piece 120;

[0073] The arc-shaped anti-skid grooves 143 and the anti-skid ridges 144 play an anti-skid role, which is convenient for doctors to operate manually. By pressing the two arc-shaped anti-skid grooves 143 by hand, the blood blocking clamp is opened, and after releasing the hand, the blood blocking clamp is clamped.

[0074] Furthermore, if Figure 6 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 110 and the second clamp 120, and the first clamp block 101 and the second clamp block 102 are arranged in parallel, and an arc transition is adopted between the first clamp block 101 and the second clamp block 102 and the two ends of the V-shape of the first clamp 110 and the second clamp 120. When the V-shaped blood blocking clamp is required for maximum vascular surgery, the turning design of the first clamp block 101 and the second clamp block 102 here is conducive to preventing the blood vessel from slipping.

[0075] In order to further improve the convenience of operation of the blood blocking clip, the first frame portion 210 and the second frame portion 220 in the support frame assembly 200 cooperate with each other to form an auxiliary knotting structure;

[0076] like Figure 7A first hook 201 is provided at both ends of the first frame 210, and a second hook 202 matching with the first hook 201 is provided at both ends of the second frame 220. The first hook 201 and the second hook 202 at the same end are symmetrically arranged, and the two cooperate with each other to form a slot for fixing sutures.

[0077] In actual application, the sutures are first used to suture the upper and lower ends of the blood vessel 10 to be sutured. The upper suture is hung and fixed on the slot between the first hook 201 and the second hook 202 at the front end, and the lower suture is hung and fixed on the slot between the first hook 201 and the second hook 202 at the rear end, so as to pull the blood vessel to suture the entire circle of the blood vessel.

[0078] 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. The scope of protection of the utility model is defined by the attached claims and their equivalents.
