Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of constructing an arterial occlusion model, and particularly relates to a vascular ligation tool for constructing an animal middle cerebral artery occlusion model. Background Art
[0002] When conducting an experiment on a middle cerebral artery occlusion model, researchers need to separate the internal carotid artery, external carotid artery, and common carotid artery, and ligate some blood vessels. Conventional operations include using a glass microprobe or sharp-tipped forceps for blunt separation, and then using a sharp-tipped curved forceps to pass a ligature from the bottom of the blood vessel to the opposite side, and then using another pair of forceps to clamp it out and complete the ligation. However, due to the small size and thin wall characteristics of the blood vessels in mice, the above threading technique has several limitations: the coarseness of the glass microprobe or forceps may cause blood vessel rupture or nerve damage; it is difficult to pass the thread from the bottom of the blood vessel to the opposite side when separating the blood vessel from the nerve; it is difficult to find the thread end brought by the forceps, resulting in an extended operation time; and the blood vessel may be damaged during the process of pulling the thread. These limitations increase the complexity of the experimental operation, significantly reduce the speed and success rate of model construction, and thus lead to unnecessary waste of experimental resources. Content of the Utility Model
[0003] The utility model discloses a vascular ligation tool for constructing an animal middle cerebral artery occlusion model, which includes a holding part, a supporting part connected to the holding device, and a separating and threading part connected to the supporting part. A threading hole for a ligature is arranged on the separating and threading part; the separating and threading part is a flat arc-shaped rod.
[0004] Preferably, the supporting part is a supporting column. One end of the supporting column is a thick end, and the other end is a thin end. The thin end is connected to the separating and threading part, and the thick end is connected to the holding part.
[0005] Preferably, the flat arc-shaped rod is made of a metal material.
[0006] Preferably, the flat arc-shaped rod forms a 90° angle with the supporting part.
[0007] Preferably, a holding hole is arranged on the holding part.
[0008] Preferably, the number of the holding holes is two.
[0009] The technical solution provided by the utility model has at least the following technical effects:
[0010] The tool disclosed in this application can make the operation process smoother when performing vascular ligation by threading the ligature through the threading hole. This is because the separating threading part used is a flat arc-shaped rod, which can directly bypass the blood vessel, thereby driving the ligature to pass through the bottom of the blood vessel. Compared with the traditional method of using two forceps (one for feeding and one for receiving), this method is simpler, more efficient, and less likely to cause blood vessel damage.
[0011] In addition, the flat arc-shaped rod used in this application is arranged at the end of the support part and is thinner than a glass microprobe or forceps. This makes it easier and more convenient to separate blood vessels and nerves. Therefore, this application provides a more efficient, simple, and safe vascular ligation tool.

[0018] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features.

[0019] Referring to Figure 1 , this embodiment discloses a vascular ligation tool for constructing an animal middle cerebral artery occlusion model, which includes a holding part 1, a support part 2 connected to the holding device, and a separating and threading part 3 connected to the support part 2. A threading hole 4 for the ligation thread is provided on the separating and threading part 3.
[0020] Referring to Figure 1 , two holding holes 5 are provided on the holding part 1, mainly for the convenience of the hand to hold the holding part 1. This design not only improves the comfort of holding but also increases the stability of holding. The design of the holding holes 5 takes into account the natural shape of the hand. The human hand is usually in a C shape, and the position and shape of the holding holes 5 exactly match the natural shape of the hand. This enables the hand to hold more naturally and comfortably, reducing the fatigue of the hand.
[0021] Referring to Figure 2 , the separating and threading part 3 is a flat arc-shaped rod, which has an appropriate arc to facilitate its smooth passing under the blood vessel, avoiding unnecessary damage to the blood vessel. The flat arc-shaped rod is at a 90° angle to the support part 2, which is equivalent to a perpendicular state, facilitating the operation of the flat arc-shaped rod. The flat arc-shaped rod is made of a metal material and has good strength and durability, which can ensure the stability and reliability of the separating and threading part 3.
[0022] The support part 2 is a support column, one end of which is a thick end and the other end is a thin end. The thin end is connected to the separating and threading part 3, and the thick end is connected to the holding part 1. The main function of the support part 2 is connection.
[0023] When performing vascular ligation, passing the ligature through the threading hole 4 can make the operation process smoother. This is because the separating and threading part 3 used is a flat arc-shaped rod, which can directly bypass the blood vessel, thus driving the ligature to pass through the bottom of the blood vessel. Compared with the traditional method of using two forceps (one for sending and one for receiving), this method is simpler, more efficient, and less likely to cause blood vessel damage.
[0024] In addition, the flat arc-shaped rod used in this application is arranged at the end of the support part 2 and is thinner than a glass microprobe or forceps. This makes it easier and more convenient to separate blood vessels and nerves. Therefore, this application provides a more efficient, simple, and safe vascular ligation tool.
[0025] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
