[0027] The technical scheme of the utility model will be described clearly and completely in combination with specific embodiments, obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0028] As Figs. 1-2As shown, the utility model discloses a kind of oral cavity and maxillofacial hemangioma clamp, comprising: first clamping part 1, first clamping part 1 includes the first clamping rod 2 and first clamping ring 3 of being connected;Second clamping part 4, second clamping part 4 includes the second clamping rod 5 and second clamping ring 6 of being connected;Connecting assembly, connecting assembly is set on first clamping rod 2 and second clamping rod 5, and first clamping part 1 and second clamping part 4 are closed connection.By setting first clamping part 1 and second clamping part 4, two clamping parts include first clamping ring 3 and second clamping ring 6 respectively, and the accommodating cavity for accommodating oral cavity and maxillofacial hemangioma is in clamping ring, to greatly increase the clamping range, so as to clamp the entire oral cavity and maxillofacial hemangioma area completely, so that the blood flow in hemangioma body can be reduced to maximum, increase the drug concentration in tumor body, and it is favorable for drug to prolong the retention time of drug in tumor body, improve the effectiveness of treatment.Using clamping ring structure, annular design can increase the area of clamping area as far as possible, so that most of oral cavity and maxillofacial hemangioma body can be clamped;And annular design makes that the whole of clamp is smooth and round, avoids piercing tumor body, and safety is greatly improved.By setting first, second two clamping parts and connecting assembly, after two clamping parts are clamped respectively in oral cavity inside and outside tumor body, by adjusting connecting assembly, the automatic fixed clamping of two clamping parts can be realized, both can keep the stability of clamping state, and can reduce manpower.The two clamping parts of the utility model adopt split design, and are connected by connecting assembly, so that the flexibility of clamp is improved.

[0029] Specifically, first clamping part 1 and second clamping part 4 are oppositely arranged, in closed state, first clamping rod 2 and second clamping rod 5 abut, and first clamping ring 3 and second clamping ring 6 abut.By oppositely arranging first clamping part 1 and second clamping part 4, in closed state, the two abut, after clamping oral cavity and maxillofacial hemangioma, first clamping part 1 and second clamping part 4 abut respectively on the inside and outside two sides of oral cavity and maxillofacial hemangioma, and the abutment position is opposite to the position of two clamping rings, which forms greater compression on the face, so as to reduce or block the blood flow of hemangioma in the ring, prevent the drug from flowing to other parts of the body with blood, and ensure the blood concentration of hemangioma.

[0030] Specifically, first clamping ring 3 protrudes towards the side close to second clamping ring 6, and in closed state, first clamping ring 3 is embedded in the inside of second clamping ring 6 (not shown in the figure).The inner diameter of second clamping ring 6 is 0.5-2mm larger than the outer diameter of first clamping ring 3.By setting second clamping ring 6 slightly larger than first clamping ring 3, first clamping ring 3 is embedded in second clamping ring 6, and in closed state, first clamping ring 3 and second clamping ring 6 are no longer abut, but are coplanar and coincident.In use, first clamping ring 3 and second clamping ring 6 form misaligned clamping, which can not only ensure the clamping of hemangioma tumor, but also disperse the clamping force through misalignment to reduce the pain of patients, thereby improving the cooperation degree of patients.

[0031] Specifically, as shown in Figs. 1-2 The connecting assembly is two sets of connecting bolts 7 and connecting nuts 8, which are arranged at the end and middle part of the first clamping rod 2 and the second clamping rod 5 respectively; wherein the movable end of each set of connecting bolts 7 penetrates the second clamping rod 5 and the first clamping rod 2 in turn, and is fixed by the corresponding connecting nut 8 to close the first clamping part 1 and the second clamping part 4. By arranging two sets of connecting bolts 7 and connecting nuts 8, two sets of connecting members are formed, wherein each set of connecting member includes a connecting bolt 7 and a matching connecting nut 8, one set of connecting member is arranged at the end of the two clamping rods away from the clamping ring, and the other set of connecting member is arranged at the middle part of the clamping rod. By using the principle of lever, the connecting bolt 7 and the connecting nut 8 at the end of the clamping rod remain in a fastened state as the fulcrum of the lever, and by adjusting the fastening degree of the connecting nut 8 at the middle part of the clamping rod, the clamping force between the first clamping ring 3 and the second clamping ring 6 can be controlled to be in a moderate position. It should be noted that the above connecting assembly can also be a buckle or a magnetic body that cooperates with each other, and the utility model does not limit this.

[0032] Specifically, as shown in Fig. 2 The first clamping rod 2 is provided with a protruding part 9 at the middle part, and a long hole 10 is arranged in the protruding part 9. In the closed state, the connecting bolt 7 penetrates the long hole 10. Due to the complex structure of the oral and maxillofacial region and the large difference in tissue thickness from top to bottom and front to back, by arranging the protruding part 9 and the long hole 10 on the first clamping rod, the fixing point of the connecting bolt 7 and the connecting nut 8 at the middle part of the clamping rod can be arranged at different positions of the long hole 9, that is, the first clamping ring 3 can be deflected at a certain angle relative to the second clamping ring 6 and still be able to maintain a fixed clamping state. That is, the utility model can adjust the angle of the first clamping ring 3 and the second clamping ring 6 to adapt to the tumor of the oral and maxillofacial region at different positions, and is more flexible to use.

[0033] Specifically, one end of the two sets of connecting bolts 7 is fixedly arranged at the end and middle part of the second clamping rod 5. Compared with the design that the connecting bolt 7 penetrates the two clamping rods in turn, by fixing one end of the connecting bolt 7 on the second clamping rod 5, since the connecting bolt 7 is integrally arranged with the second clamping rod 5, when the hemangioma clamp is closed, only the two clamping parts need to be controlled, and the fixed end of the connecting bolt 7 does not need to be additionally controlled to be attached to the second clamping rod 5, which also avoids the connecting bolt 7 from falling off, and the operation is more convenient; and since the end of the connecting bolt 7 is fixed on the second clamping rod 5, the positions of the two are fixed vertically, so when the connecting nut 8 is tightened, the direction of the connecting bolt 7 will not deviate, so that the first clamping part and the second clamping part can stably maintain a deflected state at different angles, to ensure the clamping effectiveness of the hemangioma clamp.

[0034] Specifically, the outer diameter of the first clamping ring 3 and the second clamping ring 6 is 2-6 cm, and the ring width of the first clamping ring 3 and the second clamping ring 6 is 0.2-0.5 cm. The length of the first clamping rod 2 and the second clamping rod 5 is 3-5 cm. The size of the above hemangioma clamp is designed according to clinical experience, and different specific models of small, medium and large hemangioma clamps can also be set in the range, for example, the outer diameter of the first clamping ring 3 and the second clamping ring 6 of the small hemangioma clamp can be designed to be 2 cm, the ring width is 0.2 cm, and the length of the clamping rod is 5 cm.

[0035] Specifically, the first clamping part 1 and the second clamping part 4 are both hard structures, wherein the first clamping ring and the second clamping ring are provided with elastic rubber sleeves outside. By setting the two clamping parts to be hard structures, for example, made of stainless steel, the pressure of the clamp on the surrounding tissue of the hemangioma can be ensured during use. By setting the elastic rubber sleeves outside the clamping ring, the comfort of the clamp during use can be improved, and the patient experience can be improved.

[0036] The use process of the oral and maxillofacial hemangioma clamp of the utility model is as follows: first, the connecting bolts 7 and the connecting nuts 8 at the end of the clamping rod are fastened, and the connecting bolts 7 and the connecting nuts 8 in the middle of the clamping rod are loosened, so that the hemangioma clamp is in an open state; then observe the position of the oral and maxillofacial hemangioma, extend the first clamping ring 3 into the oral cavity to surround the hemangioma, and the second clamping ring 6 is tightly attached to the skin of the face outside; observe the size of the hemangioma to determine the fastening position of the connecting nut 8 of the middle part of the clamping rod on the long hole 10, when the hemangioma is small, the first clamping ring 3 can be deflected at a certain angle relative to the second clamping ring 6, then the connecting nut 8 of the middle part of the clamping rod is tightened to fasten, so that the first clamping ring 3 and the second clamping ring 6 form a clamping pressure on the surrounding tissue of the hemangioma to block or reduce the blood reflux, ensure the concentration of the drug in the tumor, and thus ensure the treatment effect. When the treatment is completed, loosen the connecting nut 8, take out the first clamping ring 3, then clean and disinfect the hemangioma clamp, finally tighten the connecting nut 8 to keep the hemangioma clamp in a closed state and then recycle and place it for next use.

[0037] The above is further described by specific embodiments, but it should be understood that the specific description herein should not be construed as limiting the essence and scope of the present application, and various modifications made by those skilled in the art after reading the above description are within the scope of the present application.
