Description

Technical Field

[0001] The utility model relates to the technical field of modeling forceps, and more specifically, to a skin and soft tissue modeling forceps. Background Art

[0002] Critical bone defects caused by infections, traumas, tumors, etc. have always been a major challenge in the field of orthopedics, and this difficult problem has brought new treatment hopes. However, in order to effectively verify the effect of bone tissue engineering materials in promoting bone tissue regeneration, an accurate animal bone defect model is required. Currently, traditional animal bone defect modeling methods mainly rely on the experience of surgeons, resulting in inconsistent sizes of the modeled defects, which not only affects the measurement results of the newly formed bone volume after surgery, but may also lead to errors in the evaluation of bone repair effects and even experimental failures. The research on soft tissue diseases also faces similar challenges. Soft tissue injuries may be caused by factors such as overuse, metabolic abnormalities, and vascular changes, leading to soft tissue micro-injuries, which in turn cause pain, swelling, and decreased motor ability. Animal models play a key role in the research of soft tissue pathophysiology and the exploration of treatment plans.

[0003] In experiments, surgical operations such as partial resection are commonly used methods to create soft tissue defects to simulate soft tissue diseases. Generally, modeling forceps are required. Due to the inconsistency of the operations of experimental personnel, differences may occur in the position, size, and dimensions of the modeled defects, which affects the subsequent experimental observations and result comparisons.

[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a skin and soft tissue modeling forceps.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A skin and soft tissue modeling forceps includes two forcep handles. The ends of the two forcep handles are rotatably connected through a hinge shaft. Lower forcep jaws and upper forcep jaws are respectively arranged at the ends of the two forcep handles located at the hinge shaft. Bottom plates are fixedly connected to the ends of both the lower forcep jaws and the upper forcep jaws. Circular cutter heads in a semi-circular arc shape are arranged at the ends of both the lower forcep jaws and the upper forcep jaws. The bottom ends of the circular cutter heads are fixedly connected to the peripheries of the bottom plates.

[0007] By adopting the above technical solution, when in use, hold the pliers handle by hand, align the upper jaw and the lower jaw with the modeling part. At this time, grip the pliers handle tightly. Under the action of the hinge shaft, the upper and lower jaws gradually approach until they abut. Release the pliers handle, and the tissue is smoothly excised, and the modeling is completed, realizing the preparation of a semi-circular tissue defect model, reducing the difference in the size and dimensions of the excised tissue. During the excision process, the excised tissue is filled into the space formed by the bottom plate and the circular cutter head, ensuring the smooth filling and excision of the excised tissue, and solving the problem of the effective storage of the excised tissue and the separation from the modeling part in practical applications.

[0008] The present utility model is further configured as: a first arc-shaped baffle is provided on the surface of one of the bottom plates, and a second arc-shaped baffle is provided on the surface of the other bottom plate. The second arc-shaped baffle is provided with a slot for the first arc-shaped baffle to be inserted. The first arc-shaped baffle and the second arc-shaped baffle are respectively disposed at the ends of the lower jaw and the upper jaw, and the two side walls of the second arc-shaped baffle are attached to the inner side wall of the circular cutter head.

It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively

[0019] As shown in the figure, a skin and soft tissue modeling pliers includes two plier handles 1. The ends of the two plier handles 1 are rotatably connected through a hinge shaft 2. Lower jaws 3 and upper jaws 4 are respectively arranged at the ends of the two plier handles 1 located at the hinge shaft 2. Bottom plates 5 are fixedly connected to the ends of the lower jaws 3 and the upper jaws 4. Circular cutting heads 6 in the shape of a semi-circle are arranged at the ends of the lower jaws 3 and the upper jaws 4. The bottom ends of the circular cutting heads 6 are fixedly connected to the circumferences of the bottom plates 5

[0020] When in use, by holding the plier handle 1 by hand, align the upper jaw 4 and the lower jaw 3 with the modeling part. At this time, hold the plier handle 1 tightly. Under the action of the hinge shaft 2, the upper and lower jaws 3 gradually approach until they abut. Release the plier handle 1, and the tissue is smoothly excised, and the modeling is completed, realizing the preparation of a semi-circular tissue defect model, reducing the difference in the size and size of the excised tissue. During the excision process, the excised tissue is filled into the space formed by the bottom plate 5 and the circular cutting head 6, ensuring the smooth filling and excision of the excised tissue, and solving the problem of the effective storage of the tissue after excision and the separation from the modeling part in practical applications

[0021] A first arc-shaped baffle 7 is arranged on the surface of one of the bottom plates 5, and a second arc-shaped baffle 8 is arranged on the surface of the other bottom plate 5. The second arc-shaped baffle 8 is provided with a slot for inserting the first arc-shaped baffle 7. The first arc-shaped baffle and the second arc-shaped baffle are respectively placed at the ends of the lower jaw 3 and the upper jaw 4. The two side walls of the second arc-shaped baffle are attached to the inner side walls of the circular cutting head 6. Through the first arc-shaped baffle 7 and the second arc-shaped baffle 8, during the tissue cutting process, an effective blocking effect is exerted on the tissue, solving the problem that the cutting tissue is extruded excessively due to the lack of blocking during the cutting process, which affects the modeling size

[0022] Both bottom plates 5 are provided with ejection holes 9. After the tissue resection is completed, through the ejection holes 9, the tissue excised inside the circular cutter head 6 can be conveniently ejected, facilitating the detachment of the excised tissue.

[0023] The pliers handle 1 is arranged in an arc shape, and its outer surface is provided with friction lines 10 to ensure the friction force between the hand and the pliers handle 1, achieving an anti-slip effect and facilitating use.

[0024] The inner surfaces of the two pliers handles 1 are respectively provided with a first elastic sheet 11 and a second elastic sheet 12. The end of the first elastic sheet 11 is provided with a groove, and the end of the second elastic sheet 12 abuts against the end of the inner surface of the first elastic sheet 11. The end of the second elastic sheet 12 is also provided with a convex block 13 inserted into the groove. When performing the resection work and gripping the two pliers handles 1, the first elastic sheet 11 and the second elastic sheet 12 are deformed. After releasing the pliers handle 1, under the elastic force of the first elastic sheet 11 and the second elastic sheet 12, the two pliers handles 1 can automatically rebound, facilitating operation and use.
