[0023] The embodiments of the present application will be further described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0024] As shown in the accompanying Figure 1 to the accompanying Figure 5 As shown:

[0025] Example one: the utility model provides a surgical hemostatic clamp device, including clamping cylinder 1, be equipped with the clamping plate 2 of sliding connection in clamping cylinder 1, the vertical section of clamping plate 2 is '' U '' type, when clamping plate 2 moves towards clamping cylinder 1, the '' U '' type vertical section on clamping plate 2 is close to each other, the front end of clamping plate 2 is connected with mounting box 3, and mounting box 3 is equipped with the clamping part 4 of opposite extension, and the vertical section of clamping part 4 is rectangle, oval and triangle;

[0026] Pulling assembly, pulling assembly is located in clamping cylinder 1, and different positions are realized in clamping cylinder 1 by pulling assembly driving clamping plate 2.

[0027] It needs to be explained that by setting clamping plate 2 with ductility in clamping cylinder 1, when clamping plate 2 slides towards clamping cylinder 1, the two ends of clamping plate 2 can be close to each other, thereby driving clamping part 4 to be close to each other to clamp the bleeding part of patient, clamping part 4 is detachably connected in mounting box 3 through matching plate 6, and the vertical section of clamping part 4 is rectangle, oval and triangle, so that different clamping parts 4 can be replaced, different models of clamping part 4 can be installed according to the bleeding port of patient, so as to improve the stability of clamping, and under the connection of pulling assembly, the clamping force can be adjusted, so as to improve the flexibility of hemostatic clamp.

[0028] The vertical section shape of clamping part 4 includes but is not limited to rectangle, oval and triangle, and also can be other shapes, as long as clamping can be realized on blood vessel after clamping plate 2 is close to each other, different models of clamping part 4 can be set to be adjusted flexibly according to the bleeding position and bleeding state of patient.

[0029] In the embodiment, clamping cylinder 1 is composed of a rectangular column and a cylindrical column, the inside of clamping cylinder 1 is hollow, and clamping plate 2 is slidably arranged in the rectangular column in clamping cylinder 1.

[0030] It should be noted that the clamping cylinder 1 is composed of a rectangular column and a cylindrical column, the hole diameter in the cylindrical column is smaller than the hole diameter inside the rectangular column, so that the clamping plate 2 is blocked when moving to the cylindrical column, thereby avoiding the clamping plate 2 from being pulled out of the clamping cylinder 1.

[0031] In this embodiment, the clamping plate 2 is composed of a stainless steel sheet, the vertical section of the "U" shape has elasticity, and the included angle between the two is an acute angle in the free state, and the included angle is between 15 degrees and 20 degrees.

[0032] It should be noted that the included angle between the two is an acute angle in the free state, and the included angle is between 15 degrees and 20 degrees, which allows the two clamping arms of the clamping plate 2 to move closer to each other when moving inside the clamping cylinder 1, thereby allowing the clamping portion 4 to clamp the blood vessel.

[0033] In this embodiment, the mounting box 3 is fixedly connected to the end of the clamping plate 2, respectively, the opposite surfaces of the two mounting boxes 3 are provided with a placing groove 5, the top of the clamping portion 4 is provided with a matching plate 6, and the matching plate 6 is inserted into the placing groove 5.

[0034] In this embodiment, the matching plate 6 is symmetrically provided with a movable connecting positioning pin 7, the positioning pin 7 is provided with a reset spring 8, and when the matching plate 6 is inserted into the placing groove 5, the positioning pin 7 extends out of the mounting box 3.

[0035] It should be noted that after the matching plate 6 is inserted into the placing groove, the positioning pin 7 extends out of the mounting box 3 under the elastic force of the reset spring 8, thereby achieving the fixation of the clamping portion 4, and also achieving the detachable installation between the clamping portion 4 and the clamping plate 2, so that different clamping portions 4 can be selected according to the patient's condition.

[0036] In this embodiment, the number of clamping portions 4 on one hemostatic clip is two, and the opposite surfaces of the clamping portions 4 are provided with spaced-apart anti-skid portions 9.

[0037] It should be noted that the anti-skid portions 9 can effectively prevent the clamping portion 4 from sliding after being fixed on the blood vessel, thereby improving the clamping stability of the bleeding position of the patient.

[0038] In this embodiment, the pulling assembly includes a driving rod 10, a sliding rod 11, a pull rope 12, and a clamping hook 13, the driving rod 10 is located in the clamping plate 2 and in the arc-shaped portion of the "U" shape, the left and right side plates of the rectangular column of the clamping cylinder 1 are oppositely provided with limiting holes 14, and the sliding rod 11 is symmetrically connected to the two sides of the driving rod 10 and extends out of the limiting hole 14.

[0039] It should be noted that by setting the limiting hole 14 in the clamping cylinder 1, the sliding rod 11 can move in the limiting hole 14, thereby controlling the movement of the clamping plate 2 in the clamping cylinder 1.

[0040] In the embodiment, the number of the pull ropes 12 is two, one end of the pull rope 12 is fixedly connected to the end of the extended sliding rod 11, the clamping hook 13 is connected to the cylindrical sidewall of the clamping cylinder 1, and the pull rope 12 can be wound on the clamping hook 13 to be tightly wound.

[0041] It should be noted that when the pull rope 12 is continuously pulled out of the clamping cylinder 1, the clamping plate 2 connected at the other end moves in the clamping cylinder 1, and when the clamping part 4 is fixed to the bleeding site of the patient, the pull rope 12 can be wound on the clamping hook 13 to be tightly tied, thereby ensuring that the position of the clamping part 4 is fixed, and the medical staff does not need to hold the hemostat clamp to clamp it all the time.

[0042] As can be seen from the above, when the bleeding site of the patient needs to be hemostatic, the hemostat clamp is taken out, the clamping part 4 is placed at the bleeding site of the patient, when the clamping part 4 is not suitable, the positioning pin 7 is moved to be separated from the installation box 3, so that the matching plate 6 can be taken out from the placing groove 5, at this time, the connected clamping part 4 can be taken down, the clamping part 4 has multiple models, and different clamping parts 4 can be installed according to the bleeding site of the patient.

[0043] When the installation is completed, the pull rope 12 is pulled, the pull rope 12 is fixedly connected with the sliding rod 11, the sliding rod 11 moves in the limiting hole 14, the clamping plate 2 moves in the clamping cylinder 1, the two clamping arms of the clamping plate 2 are driven to approach each other, thereby the two clamping parts 4 approach each other, the bleeding site of the patient is clamped and blocked, when the clamping is completed, the pull rope 12 is wound on the clamping hook 13, the position and clamping force of the clamping part 4 are fixed, and the movement of the clamping part 4 is prevented, thereby the clamping of the bleeding wound of the patient is realized.

[0044] The embodiments of the utility model are given for example and description, although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary, and cannot be understood as the limitation of the utility model, and the ordinary skilled in the art can change, modify, replace and transform the above-mentioned embodiments within the scope of the utility model.
