Experimental fracture molding clamp and using method thereof

Abstract

The invention discloses an experimental fracture molding clamp, comprising a first handle and a second handle; the first handle and a second ring clamping arm are integrally shaped, and the second handle and a first ring clamping arm are integrally shaped; the first handle and the second handle are hinged and installed through a connecting shaft, the front end of the first ring clamping arm is integrally shaped with a first clamp head, and the front end of the second ring clamping arm is integrally shaped with a second clamp head. By using an arc structure between the first ring clamping arm and the second ring clamping arm, the device can effectively stride over the stoppage at thick muscle of four limbs of a mouse; an injection hole on the second clamp head can effectively inject liquor in an injector to corresponding tissues after pinching off bone tissues, thereby avoiding additional troubles for changing clamp in injecting liquor and reducing use of unnecessary tools; therefore, the clamp can effectively reduce unnecessary operations in mouse fracture molding process, and has very high practicable value.

Description

technical field [0001] The invention relates to the technical field of fracture modeling, in particular to a fracture modeling forceps for experiments and a use method thereof. Background technique [0002] Fracture modeling refers to the manufacture of animal models used to study the healing of animal fractures. Traditional animal models mostly use rats or mice as experimental subjects, and generally use special modeling brackets for modeling, such as figure 1 It is a commonly used molding bracket, which includes a base 102, and the lower end of the base 102 is provided with a height adjustment nut 101, and the left and right sides of the base 102 are equipped with upper-layer steel plates 108 through columns 105 and nuts 106, and the outer sides of the columns 105 The limit sleeve 104 is sleeved at the end, and the lower end of the limit sleeve 104 is limited by the limit nut 103, and the limit sleeve 104 is installed through a connecting plate, and a center column 107 is ...

[0002] Fracture modeling refers to the manufacture of animal models used to study the healing of animal fractures. Traditional animal models mostly use rats or mice as experimental subjects, and generally use special modeling brackets for modeling, such as figure 1 It is a commonly used molding bracket, which includes a base 102, and the lower end of the base 102 is provided with a height adjustment nut 101, and the left and right sides of the base 102 are equipped with upper-layer steel plates 108 through columns 105 and nuts 106, and the outer sides of the columns 105 The limit sleeve 104 is sleeved at the end, and the lower end of the limit sleeve 104 is limited by the limit nut 103, and the limit sleeve 104 is installed through a connecting plate, and a center column 107 is installed in the middle of the connecting plate. And the lower end of the center column 107 is provided with a circular weight 111 (the circular weight 111 is generally a 500g weight), and the upper end of the base 102 is equipped with an anvil 109 through a lock nut 110 at the corresponding center column 107, using this device When making the model, the rat is first fixed on the anvil 109, and the center column 107 is used to drive the circular weight 111 to fall freely, thereby crushing the bone of the rat placed on the anvil 109 to realize fracture modeling. In practice, the operation is cumbersome, and the accuracy is not easy to control during the actual modeling process. After the modeling, multi-tool cooperation is required to inject the fracture site, so it is not conducive to popularization. If we can invent a precision that is easy to control, simple to operate, and easy to Such problems can be solved by using a new modeling tool that can greatly reduce the difficulty of injecting medicine into the fracture site after modeling. For this reason, we provide an experimental fracture modeling forceps and its use method
