DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-7 The present invention is described in further detail.

[0029] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] See also Figure 1-7 As shown, a combined hemostatic clip is shown, including a hemostatic clip body 1, which is made of a new type of degradable magnesium metal material, and the magnesium metal material includes: 1.5-6% Zn, 0.01-0.1% Si, one or more of the elements such as Mn, Fe, Cu, Ti, Ni, Al, etc., and the rest is Mg. During preparation, the magnesium alloy material is rolled into a plate with a thickness of 0.5mm to 5.0mm in the form of alternating hot and cold, and then the hemostatic clip body 1 is processed on the 0.5mm to 5.0mm plate using laser cutting equipment.

[0031] The hemostatic clip body 1 includes a first clamp arm 1a and a second clamp arm 1b which are integrally connected. The first clamp arm 1a and the second clamp arm 1b are both arc-shaped and arranged in a V-shape. The first clamp arm 1a and the second clamp arm 1b can swing around a first direction and move relatively close to each other. The first direction is perpendicular to the plane where the hemostatic clip body 1 is located. Anti-slip corrugations 20 are also provided on the inner side of the first clamp arm 1a and the second clamp arm 1b, respectively. The anti-slip corrugations 20 can prevent the first clamp arm 1a and the second clamp arm 1b from sliding relative to each other on the blood vessel. The outer ends of the first clamp arm 1a and the second clamp arm 1b are also provided with protrusions 21 for cooperating with an applicator. The applicator is a prior art and is used to take and place the hemostatic clip.

[0032] In this embodiment, combined with Figure 1-2 As shown, the two sides of the hemostatic clip body 1 are respectively provided with first elastic bodies 2, and the two first elastic bodies 2 are also V-shaped, and the two are fixed to the hemostatic clip body 1 through the cooperation of the pin shaft and the pin hole. Among them, the first elastic body 2 is made of a polymer material with good elasticity, and the polymer material can be one of polydioxanone polyester, para-dioxanone, polyglycolic acid, polyglycolide (PGA), and polyglycol carbonate material. The first elastic body 2 includes two first elastic arms 2a connected in one piece, and the two first elastic arms 2a are respectively and correspondingly arranged on the first clamp arm 1a and the second clamp arm 1b, and the extension direction of each first elastic arm 2a is the same as the extension direction of the corresponding clamp arm.

[0033] When the doctor operates the hemostatic clip body 1, he may retract or open the first clamp arm 1a and the second clamp arm 1b multiple times according to the progress of the operation. After the deformation, the first clamp arm 1a and the second clamp arm 1b can be quickly restored under the drive of the two first elastic arms 2a. In this way, the doctor can adjust the first clamp arm 1a and the second clamp arm 1b multiple times according to the needs of the operation to better clamp the blood vessel, effectively improving the doctor's surgical accuracy and efficiency; at the same time, the two first elastic bodies 2 can also limit the hemostatic clip body 1 from both sides to prevent the first clamp arm 1a and the second clamp arm 1b from being relatively misaligned when clamping the blood vessel.

[0034] In this embodiment, if Figure 3-4 As shown, a first connecting portion 1c is integrally arranged between the first clamping arm 1a and the second clamping arm 1b, an arc-shaped first groove 3 is opened on the inner side of the first connecting portion 1c, and limiting blocks 5 are respectively arranged on both sides of the groove of the first groove 3 of the first connecting portion 1c, and a second elastic body 4 is arranged in the first groove 3. The second elastic body 4 is a V-shaped energy storage spring, which includes two integrally connected second elastic arms 4a, one end of the two second elastic arms 4a connected to each other is in conflict with the groove wall of the first groove 3, and one end of the two second elastic arms 4a away from each other is in conflict with the two limiting blocks 5 respectively.

[0035] When the doctor uses the hemostatic clip body 1, the second elastic body 4 can achieve continuous elastic squeezing of the first connecting portion 1c and the two clamp arms through the cooperation of the limit block 5 and the first groove 3, which can not only further improve the restoring force of the hemostatic clip body 1, but also due to the presence of the second elastic body 4, the first clamp arm 1a and the second clamp arm 1b will not be too close to each other, which can prevent both from causing damage to the blood vessels.

[0036] In this embodiment, the first groove 3 has two ports 3a at both ends, and the two ports 3a are arranged along the first direction. The first elastic body 2 has two ports 3a and is respectively disposed on the two sides of the hemostatic clip body 1. The first elastic body 2 also includes a second connecting portion 2b integrally disposed between the two first elastic arms 2a, and the two second connecting portions 2b are respectively shielded on the two ports 3a, and the two side portions of the two second connecting portions 2b opposite to each other are respectively provided with limiting grooves 6, and the two side portions of the second elastic body 4 are respectively embedded in the two limiting grooves 6.

[0037] In this way, the two first elastic bodies 2 can cooperate with the two clamp arms and limit the second elastic body 4 in the first groove 3, thereby preventing the second elastic body 4 from detaching from the first groove 3 during the deformation process and affecting its elastic extrusion on the two clamp arms; at the same time, the two first elastic bodies 2 can be linked with the second elastic body 4 through the limiting groove 6, further improving the elastic force of the hemostatic clip body 1.

[0038] In this embodiment, if Figure 3 and Figure 6 As shown, the end of the first clamp arm 1a is provided with a hook 7, and the hook 7 has a hook groove 7a, and the end of the second clamp arm 1b is provided with a second groove 22, and a first spring 23 is provided in the second groove 22. A clamp block 8 is connected to the first spring 23, and the clamp block 8 can be extended and retracted under the elastic force of the first spring 23 and relatively engaged with the hook groove 7a. When the first clamp arm 1a and the second clamp arm 1b are relatively close or relatively separated, the clamp block 8 can be smoothly embedded in the hook groove 7a or separated from the hook groove 7a, which greatly facilitates the doctor's operation of the hemostatic clip and improves the doctor's surgical efficiency.

When the first clamp arm 1a and the second clamp arm 1b are relatively brought close together, the doctor can engage the plurality of first locking teeth 10 and the plurality of second locking teeth 12 at different positions according to the needs of the operation, so that the clamping distance between the first clamp arm 1a and the second clamp arm 1b can be adjusted to clamp blood vessels of different diameters, thereby effectively improving the accuracy of the operation.

When the locking plate 9 is inserted into the locking groove 11, the doctor can drive the locking plate 9 to rotate through the first driving member 13 and keep the first locking tooth 10 away from the second locking tooth 12 appropriately, so as to avoid the first locking tooth 10 and the second locking tooth 12 from interfering with each other during the process of the locking plate 9 being inserted into the locking groove 11.

[0041] Specifically, the first driving member 13 includes a driving groove 13a opened at the outer end of the first clamping arm 1a, a driving rod 13b slidably arranged in the driving groove 13a, a second spring 13d sleeved on the driving rod 13b, and a first transmission rod 13c connected to the lock plate 9 and perpendicular to the lock plate 9. The driving groove 13a is connected to the mounting groove 24, and the two ends of the second spring 13d are respectively connected to the driving rod 13b and the groove wall of the driving groove 13a. The sliding direction of the driving rod 13b is perpendicular to the extension direction of the rotation axis of the lock plate 9. The inclined surfaces of the driving rod 13b and the first transmission rod 13c that are close to each other are matched, and the mutually matched inclined surfaces are respectively inclined along the direction from the driving rod 13b to the first transmission rod 13c toward the direction away from the lock plate 9. In this way, when inserting the locking plate 9 into the locking slot 11 , the doctor can squeeze the first transmission rod 13 c by operating the driving rod 13 b, thereby driving the locking plate 9 to rotate and relatively separating the first locking tooth 10 and the second locking tooth 12 , so as to facilitate the locking plate 9 to go deeper into the locking slot 11 .

[0042] In this embodiment, the lock plate 9 is hinged to the mounting groove 24 through a hinge shaft 25.

The first lock tooth 10 and the third spring 26 are located on the same side of the lock plate 9.

[0043] When the driving rod 13b is pressed, the driving rod 13b approaches and pushes the first transmission rod 13c, and the first transmission rod 13c pushes the first plate body 9a to rotate, and the first plate body 9a drives the second plate body 9b to rotate and makes the first locking tooth 10 appropriately away from the second locking tooth 12, so that the lock plate 9 can be smoothly inserted into the lock groove 11; after the insertion is completed, the driving rod 13b is released, and the driving rod 13b is reset under the action of the second spring 13d, and the first plate body 9a is reset under the action of the third spring 26 and drives the second plate body 9b to rotate, and the multiple first locking teeth 10 are tightly engaged with the multiple second locking teeth 12 driven by the second plate body 9b.

The second transmission rod 17 and the locking rod 18 have an inclined surface matched with each other at one end surface close to each other, and the end of the locking rod 18 away from the second transmission rod 17 can be inserted into the locking hole 16 or separated from the locking hole 16. A second driving member 19 for pulling the second transmission rod 17 is also provided on the lock plate 9.

[0045] The side of the second transmission rod 17 is provided with a matching groove 28, and a groove wall of one side of the matching groove 28 matches with an end face inclined surface of the locking rod 18, and the two matching inclined surfaces are respectively inclined in the direction from the second transmission rod 17 to the locking rod 18 toward the direction close to the locking rod 18. When the locking plate 9 is inserted into the locking groove 11, the second driving member 19 can pull the second transmission rod 17, and the second transmission rod 17 lifts the locking rod 18 through the matching of the inclined surface of the locking rod 18, so that the locking rod 18 is inserted into the locking hole 16, thereby realizing the relative locking between the first clamp arm 1a and the second clamp arm 1b, and effectively avoiding the lateral relative displacement between the first clamp arm 1a and the second clamp arm 1b to affect the clamping effect of the two on the blood vessel.

[0046] In this embodiment, if Figure 6-7 As shown, the second driving member 19 includes a driving plate 19a arranged on a side of the locking plate 9 away from the first locking tooth 10, and a slot 19b opened on the driving plate 19a, the slot direction of the slot 19b is opposite to the slot direction of the lock slot 11, and a mating head 29 is provided at one end of the second transmission rod 17 away from the locking rod 18, and a gap 19c for accommodating the mating head 29 is provided between the driving plate 19a and the locking plate 9.
