Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical model technology, and in particular relates to a simulation model for vascular sheath stripping and ligation suturing. Background Technology
[0002] Medical models are medical simulation devices used or touched in medicine, including whole simulated human bodies, simulated human body parts, or simulated human body parts, as well as medical instruments that are necessary for medical use. These include: first aid skills training models, nursing skills training models, maternal and infant skills training models, diagnostic skills training models, human acupuncture models, and human anatomy models.
[0003] In today's medical environment and hospitals, doctors have strict qualification requirements, resulting in fewer opportunities for young doctors to perform surgeries, which hinders their growth and progress. Moreover, vascular sheath removal surgery places even stricter demands on doctors. In addition, senior surgeons need lifelong learning and continuous updating of their vascular sheath removal techniques. Therefore, we provide a simulation model of vascular sheath removal and ligation suturing to address the aforementioned problems. Utility Model Content
[0004] The purpose of this invention is to provide a simulation model for vascular sheath stripping and ligation suturing, which solves the problem of young doctors lacking surgical practice in the prior art by coordinating the first and second blood vessels.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a simulation model of vascular sheath stripping and ligation suturing, including a second blood vessel, a first blood vessel connected to the outer wall of the second blood vessel, a vascular sheath membrane fixedly wrapped on the outer walls of the first and second blood vessels, and the same lymph node fixedly connected to the inner walls of the second blood vessel and the first blood vessel that are close to each other.
[0007] By adopting the above technical solution, the second blood vessel and the first blood vessel are Y-shaped and have vascular sheaths on their surfaces. Furthermore, lymph nodes are connected between the second blood vessel and the first blood vessel. This tissue structure simulates the structure of a real lung.
[0008] The present invention is further configured such that multiple anti-slip patterns are arranged in a ring on the outer wall of the second blood vessel, and two adhesive strips are fixedly connected to the outer walls of both the second blood vessel and the first blood vessel.
[0009] By adopting the above technical solution, the adhesive tape can be adhered to the experimental table to fix the first and second blood vessels, thereby facilitating the trainees to conduct simulation training.
[0010] The present invention is further configured such that a first filling column is inserted into the second blood vessel, and a second filling column is inserted into the first blood vessel.
[0011] By adopting the above technical solution, the first and second filling columns are inserted into the second and first blood vessels to expand them, thereby preventing them from being flattened and deformed during storage.
[0012] The present invention is further configured such that the second blood vessel and the first blood vessel are Y-shaped, and the vascular sheath, the second blood vessel, and the first blood vessel are made of conductive materials that mimic the human body.
[0013] By adopting the above technical solution, the vascular sheath, the first blood vessel, and the second blood vessel are all made of bio-simulation materials with conductive properties. They can be cut and coagulated under high-energy surgical equipment, and can exhibit characteristics similar to human tissues such as separation, adhesion, blackening and charring, and odor release, making the touch realistic.
[0014] This utility model has the following beneficial effects:
[0015] This invention features a Y-shaped second and first blood vessel with a vascular sheath on its surface, and lymph nodes connecting the second and first blood vessels. This tissue structure simulates the structure of a real lung, allowing for training in lung inflation, vascular sheath stripping, and vascular ligation and suturing with realistic results, achieving excellent learning and training objectives. The second and first blood vessels are connected to an external blood supply connector via a blood inlet interface. The external blood supply connector is connected to a blood bag via a blood supply vessel and a blood control valve. The vascular sheath, first blood vessel, and second blood vessel are all made of bio-simulation materials with conductive properties, allowing for cutting and coagulation under high-energy surgical equipment. They exhibit characteristics similar to the separation, adhesion, blackening, charring, and odor release of human tissue, making them not only realistic in feel but also supporting the operation of basic surgical skills under real surgical instruments.
[0016] The second and first blood vessels of this invention are Y-shaped and have vascular sheaths on their surfaces. Lymph nodes are fixedly connected between the first and second blood vessels, which can well simulate the structure of a real lung. Moreover, the vascular sheath, the first blood vessel, and the second blood vessel are made of conductive biomimetic materials, which have a realistic tactile feel, thus enabling realistic skill operations.

They can be cut and coagulated under high-energy surgical equipment, and can exhibit characteristics similar to human tissues such as separation, adhesion, blackening and charring, and odor release.

Lymph nodes 3 are connected between the second blood vessel 6 and the first blood vessel 4. This tissue structure simulates the structure of a real lung and can be used for training such as inflating the lung, stripping the vascular sheath, and ligating and suturing blood vessels. The effect is realistic and can achieve a good learning and training purpose. The second blood vessel 6 and the first blood vessel 4 are connected to an external blood supply connector through a blood inlet interface. The external blood supply connector is connected to a blood bag through a blood supply vessel and a blood control valve.
[0032] The vascular sheath 1, the first blood vessel 4, and the second blood vessel 6 are all made of bio-simulation materials with conductive properties. They can be cut and coagulated under high-energy surgical equipment, exhibiting characteristics similar to the separation, adhesion, blackening and charring, and odor release of human tissue. This not only makes them feel realistic but also supports the operation of basic surgical skills under real surgical instruments. Furthermore, anti-slip texture 7 is set on the outer wall of the second blood vessel 6 to prevent slipping when gripped. Adhesive tape 5 can be attached to the experimental table to fix the first blood vessel 4 and the second blood vessel 6, thereby facilitating the trainee's simulation training.
