[0001] The present application relates to the technical field of experimental tooling, and in particular to a tooling for preparing an acute trauma model of a large animal. Background Art

[0002] In the inspection of medical devices, evaluating the healing performance of different wound repair materials is a crucial part. This involves the cross-integration of multiple disciplines such as materials science, biology, and medicine, aiming to find new dressing materials that can effectively promote wound healing, reduce infection risks, and relieve patients' pain.

[0003] Traditional animal trauma model preparation methods mostly use manual operations, such as using a scalpel or scissors to directly cut the skin. However, this method has the disadvantages of complex operation, long time consumption, difficulty in accurately controlling the size of the wound, and severe pain for the animals. It is also easy to introduce human errors during the operation, resulting in inaccurate and non-repeatable experimental results. Utility Model Content

[0004] In order to make up for the above deficiencies, the present application provides a tool for preparing an acute trauma model of large animals to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is:

[0010] Furthermore, the horizontal cutting mechanism includes a horizontal plate, two side plates, two raised blocks, two slide grooves and a horizontal knife.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0025] Example:

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A tool for preparing an acute trauma model of a large animal includes a block box 1, the interior of which is designed as a hollow structure, which cleverly provides sufficient installation space for an adjustment mechanism 4 and a horizontal cutting mechanism 5, thereby ensuring efficient operation and precise cutting of the tool.

[0027] See also Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 A tool for preparing an acute trauma model of a large animal, comprising a square box 1 with a handle 2 installed on the top and an annular cutting mechanism 3 installed on both sides of the outer wall, an adjustment mechanism 4 fixedly connected to the top of the square box 1, a horizontal cutting mechanism 5 fixed by bolts at the telescopic end of the adjustment mechanism 4, a grip opening is opened on the side wall of the handle 2, and a silicone block 21 is provided on the top of the grip opening; the annular cutting mechanism 3 comprises two threaded heads 31, two blades 32, two sliding grooves 33 and two locking rings 34; the adjustment mechanism 4 comprises a support plate 41, a battery 42 and two electric telescopic cylinders 43; the horizontal cutting mechanism 5 comprises a cross plate 51, two side plates 52, two protruding blocks 53, two sliding grooves 54 and a horizontal knife 55.

[0028] Among them, the handle 2 is an important part of the tooling. It not only provides the convenience of holding the tooling for the operator, but also enhances the comfort and stability of use through its special design. In this tooling, a grip is provided on the side wall of the handle 2. This design allows the operator to hold the handle more naturally and reduce hand fatigue caused by long-term operation. What is more considerate is that a silicone block 21 is also provided on the top of the grip. The silicone block 21 is a soft, non-slip material with a fine texture and a comfortable touch. When the operator holds the handle, the silicone block 21 can fit tightly to the palm, providing additional friction to prevent the handle from slipping during operation. This not only improves the safety of the operation, but also ensures the accuracy of the preparation of the trauma model.

[0029] Among them, the annular cutting mechanism 3 plays a vital role, which is responsible for forming a preliminary square incision on the animal skin. Two thread heads are fixed on both sides of the square box 1 respectively, which serve as guide rails for the blade 32 to slide, and also provide a rotation axis for the locking ring 34. The blade 32 is the core part of the annular cutting mechanism, and the locking ring 34 is used to lock the adjusted blade 32. They are responsible for the actual cutting work. When using the annular cutting mechanism 3, first adjust the position of the blade 32 on the thread head 31 according to the experimental needs. By rotating the locking ring 34, the blade 32 slides along the thread head 31 in the sliding groove 33 until the required cutting depth is reached. Then, the opposite surfaces of the blade 32 are attached to the two sides of the square box 1 to ensure the accuracy and stability of the cutting. Finally, the square box 1 is pushed to cut the skin through the handle 2, and cut twice horizontally and vertically, so that the blade 32 forms a preliminary square incision on the animal skin.

[0030] Among them, the adjustment mechanism 4 plays a vital role. It is responsible for controlling the up and down movement of the horizontal cutting mechanism 5 to adapt to the cutting requirements of different heights and depths. The support plate 41 is the main structure of the adjustment mechanism 4. It is fixed on both sides of the inner wall of the block box 1 to provide stable support for the entire adjustment mechanism 4. The support plate 41 has a flat surface and is used to install the battery 42 and the electric telescopic cylinder 43. The battery 42 serves as the energy supply of the adjustment mechanism 4 and provides the required electrical energy for the two electric telescopic cylinders 43. The electric telescopic cylinder 43 is the core power component of the adjustment mechanism 4, which controls the up and down movement of the horizontal cutting mechanism 5 through telescopic movement. When the cutting depth needs to be increased, the operator can control the telescopic end of the electric telescopic cylinder 43 to extend downward to make the horizontal cutting mechanism 5 descend; conversely, when the cutting depth needs to be reduced, the telescopic end of the electric telescopic cylinder 43 is controlled to be retracted upward to make the horizontal cutting mechanism 5 rise. In this way, the adjustment mechanism 4 can achieve precise control of the height and depth of the horizontal cutting mechanism 5 to ensure the accuracy and reliability of the preparation of the trauma model.

[0031] Among them, the horizontal cutting mechanism 5 is the key part for performing the actual cutting operation. The mechanism ensures horizontal skin excision through precise design and construction. The horizontal plate, as the main part of the horizontal cutting mechanism 5, carries the side plate 52 and the horizontal knife 55. The two ends of its surface are respectively connected to the telescopic ends of the two electric telescopic cylinders 43 by bolts, so that the horizontal plate 51 can move up and down under the drive of the electric telescopic cylinder 43. The two side plates 52 are respectively located on both sides of the horizontal plate 51 and are fixedly connected to the opposite ends of the horizontal plate 51 and the horizontal knife 55. Two slide grooves 54 are provided on the side wall of the side plate 52, and these slide grooves 54 cooperate with the protruding blocks 53 on the inner wall of the block box 1 to achieve the stable sliding of the horizontal cutting mechanism 5 in the block box 1. The horizontal knife 55 is the cutting tool of the horizontal cutting mechanism 5, and its sharpness and straightness are crucial to the cutting effect. The two ends of the surface of the horizontal knife 55 are fixedly connected to the side plates 52 to ensure a stable posture during the cutting process. When using the horizontal cutting mechanism 5 for cutting, firstly, the height of the horizontal plate 51 is adjusted by the electric telescopic cylinder 43 in the adjustment mechanism 4, so that the horizontal knife 55 reaches the required cutting depth. Then, the operator positions the tooling at the position where cutting is required, and uses the horizontal knife 55 to cut the skin.

[0032] The horizontal plate 51, the two side plates 52 and the horizontal blade 55 are made into a whole by an integrated molding technology. Such a design not only ensures the precise matching between the components and eliminates assembly errors, but also makes the entire mechanism more durable and not easy to deform or damage.

[0033] The working principle of the tooling for preparing large animal acute trauma models is as follows: when cutting the skin, the user operates the block box 1 through the handle 2, and slides and connects with the thread head 31 through the sliding groove 33, and then adjusts the position of the blade 32 on the thread head 31 until the desired cutting depth is reached. Then, by rotating the locking ring 34 and threading it with the thread head 31, the blade 32 is locked, and the user cuts twice horizontally and vertically, so that the blade 32 forms a preliminary square incision on the animal skin. The position of the blade 32 is restored, and the position of the horizontal cutting mechanism 5 is controlled by the adjustment mechanism 4. The height of the horizontal plate 51 is adjusted by the electric telescopic cylinder 43 in the adjustment mechanism 4, so that the horizontal knife 55 reaches the desired cutting depth. Then, the operator positions the tooling at the position where cutting is required, and uses the horizontal knife 55 to remove the skin.

[0034] It should be noted that the specific models and specifications of the blade 32, battery 42, electric telescopic cylinder 43, and horizontal knife 55 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0035] The power supply and principle of the battery 42 and the electric telescopic cylinder 43 are clear to those skilled in the art and will not be described in detail here.

[0036] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
