Description

Technical Field

[0001] The utility model relates to a basic microsurgery training device, in particular to an operating table for microsurgeons to perform vascular anastomosis training, and belongs to the technical field of medical teaching and training equipment. Background Art

[0002] Vascular anastomosis is one of the most basic skills for microsurgeons. This skill requires high operational requirements for doctors. To master the skill of vascular anastomosis, a lot of practical training is required. At present, the skill training of vascular anastomosis is generally carried out using experimental animals. If live animals are used, relevant applications must be filled out and animal experiment ethics review must be passed. The whole process is relatively cumbersome, and the acquisition of live experimental animals is also quite troublesome, which is not conducive to the development of skill training.

[0003] If silicone tubes or animal ex vivo blood vessels are directly used as simulated blood vessels for vascular anastomosis training, there is no need to go through tedious animal experiment ethics review, and simulated blood vessels are easier to obtain and more suitable for skill training. However, ordinary training operation tables lack effective devices to fix simulated blood vessels, which are prone to displacement during training operations and are inconvenient to operate. In addition, there is no blood flow inside the simulated blood vessels, and the arterial blood supply and venous blood return of the simulated blood vessels cannot be simulated. Therefore, the actual situation of the operation cannot be fully simulated, and the actual effect of vascular anastomosis cannot be objectively considered. It can only be subjectively evaluated by appearance inspection.

[0004] To this end, we have developed a microsurgical vascular anastomosis training operating table. By effectively fixing the simulated blood vessels and connecting them to pulsed water flow or constant water flow, the simulated blood vessels can be used on the vascular anastomosis training operating table to simulate the arteries and veins of living animals to perform simulation training operations of vascular anastomosis, and the actual effect of vascular anastomosis can be objectively evaluated. Utility Model Content

[0005] The utility model aims to provide a microsurgery vascular anastomosis training operation table, which is connected with a pulse water flow or a constant water flow for use, and can use simulated blood vessels on the vascular anastomosis training operation table to simulate the arteries or veins of living animals to perform simulation training operations of vascular anastomosis.

[0006] The specific technical solutions adopted by this utility model are as follows:

[0007] A microsurgical vascular anastomosis training operation table is provided with a horizontally arranged base plate; at the middle position of the front and rear of the top surface of the base plate, and slightly to the left, a fixed upwardly protruding fixing block is provided. The fixing block is provided with a left seat hole that penetrates horizontally from left to right. A left flat-tip needle is fixedly inserted into the left seat hole from left to right. The connecting seat and the needle tube of the left flat-tip needle are respectively exposed outward from the left and right sides of the fixing block; at the middle position of the front and rear of the top surface of the base plate, and slightly to the right, there is a concave sliding groove that horizontally penetrates through to the right side wall of the base plate. A slider that can slide horizontally left and right along the sliding groove is installed in the sliding groove. The upper part of the slider extends upward above the top surface of the base plate. A nut is fixedly embedded in the part of the slider within the sliding groove, and a lead screw that horizontally penetrates through the nut is threadedly connected to the nut. A socket is provided on the left side wall of the sliding groove. The left end head of the lead screw is rotatably clamped in the socket on the left side wall of the sliding groove through a chuck, thereby forming a lead screw that can rotate in place. The right end of the lead screw extends outside the right side wall of the base plate, and a rotating handle is fixedly connected to the right end head of the lead screw; the part of the upper part of the slider that extends above the top surface of the base plate is provided with a right seat hole that penetrates horizontally from right to left. A right flat-tip needle is fixedly inserted into the right seat hole from right to left. The needle tube and the connecting seat of the right flat-tip needle are respectively exposed outward from the left and right sides of the slider; the needle tubes of the left flat-tip needle and the right flat-tip needle are arranged oppositely at intervals from left to right above the top surface of the base plate. A simulated blood vessel that is horizontally arranged from left to right is also provided on the top surface of the base plate. The two ends of the simulated blood vessel are respectively fixedly sleeved on the needle tubes of the left flat-tip needle and the right flat-tip needle. This vascular anastomosis training operation table is also equipped with a liquid outlet pipeline. One end of the liquid outlet pipeline is connected to the connecting seat of the left flat-tip needle, and the other end is connected to an output end head.

[0008] The vascular anastomosis training operation table of the present utility model can effectively fix the simulated blood vessel. When performing vascular anastomosis training, after installing the simulated blood vessel, connect the liquid supply pipeline of pulsed water flow or constant water flow to the connecting seat of the right flat-tip needle, and place the output end head of the liquid outlet pipeline in a measuring cylinder. Then, the simulated blood vessel can be used to simulate the arterial blood vessel or venous blood vessel of a living animal. Then, vascular anastomosis training of cutting and suturing the simulated blood vessel can be carried out on this vascular anastomosis training operation table. After the training is completed, the actual effect of vascular anastomosis can be objectively evaluated by counting the flow rate of the incoming and outgoing liquids and monitoring the leakage situation of the anastomosis site. The right flat-tip needle of this vascular anastomosis training operation table is mounted on a slider that can be adjusted horizontally left and right. Thus, the distance of the simulated blood vessel anastomosis site can be manually adjusted to facilitate operation training, and at the same time, it is also conducive to making full use of simulated blood vessels of different lengths and saving consumables. This vascular anastomosis training operation table has a simple structure, is easy to operate, and has a low cost. Using it for microsurgical vascular anastomosis training does not require the use of living animal blood vessels, is convenient to implement, and is conducive to the development of skill training.

A section of simulated blood vessel 9 arranged horizontally from left to right is also provided on the top surface of the base plate 1. The two ends of the simulated blood vessel 9 are respectively fixedly sleeved on the needle tubes of the left flat-tip needle 3 and the right flat-tip needle 8. This vascular anastomosis training operation table is also equipped with a liquid outlet pipeline 10. One end of the liquid outlet pipeline 10 is connected to the connecting seat of the left flat-tip needle 3, and the other end is connected to an output end 11.

[0017] Further, the sliding groove 4 adopts an inverted T-shaped sliding groove or a dovetail sliding groove, and the shape of the slider 5 matches the shape of the sliding groove 4.

[0018] Further, the simulated blood vessel 9 adopts a silicone tube or an ex vivo blood vessel of an animal.

[0019] Further, the connecting seats of the left flat-tip needle 3 and the right flat-tip needle 8 both adopt connecting seats with external-threaded Luer connectors, so as to be quickly connected with the internal-threaded Luer ports of the liquid supply pipeline and the liquid outlet pipeline 10.

[0020] Further, the needle tube length of the right flat-tip needle 8 is greater than the needle tube length of the left flat-tip needle 3.

[0021] Further, two semi-circular counterbores 1.1 are provided at the front and rear edges of the base plate 1, and four I-shaped thumb tacks 12 are provided. When performing vascular anastomosis training, after placing the base plate 1 on the wooden tabletop, the four I-shaped thumb tacks 12 can be used to press on the wooden tabletop, and the edges of the handle parts of the I-shaped thumb tacks 12 are used to press tightly on the semi-circular counterbores 1.1 of the base plate 1, thereby fixing the base plate 1.

[0022] The usage method of this vascular anastomosis training operation table is as follows:

[0023] (1). Fix the base plate 1 on the wooden tabletop through the I-shaped thumb tacks 12, rotate the rotating handle 7.2 of the lead screw 7 to adjust the position of the right flat-tip needle 8, so that the distance between the left flat-tip needle 3 and the right flat-tip needle 8 matches the length of the simulated blood vessel 9, and then fix the two ends of the simulated blood vessel 9 on the needle tubes of the left flat-tip needle 3 and the right flat-tip needle 8 respectively.

[0024] (2). When it is necessary to use the simulated blood vessel 9 to simulate the arterial blood vessel of a living animal, connect the liquid supply pipeline of the arterial blood supply simulation device developed by the inventor to the connecting seat of the right flat-tip needle 8, and the arterial blood supply simulation device provides pulsed water flow for this vascular anastomosis training operation table. Place the output end 11 of the liquid outlet pipeline 10 in the measuring cylinder, and then the simulated blood vessel 9 can be used to simulate the arterial blood vessel of a living animal. Then, vascular anastomosis training of cutting and suturing the simulated blood vessel 9 can be carried out on this vascular anastomosis training operation table.

When it is necessary to use the simulated blood vessel 9 to simulate the venous blood vessel of a living animal, connect the liquid supply pipeline of the hanging high infusion bag to the connecting seat of the right flat-tip needle 8, and the infusion bag provides a constant water flow for this vascular anastomosis training operation table. Place the output end 11 of the liquid outlet pipeline 10 in the measuring cylinder, and then the simulated blood vessel 9 can be used to simulate the venous blood vessel of a living animal. Then, vascular anastomosis training of cutting and suturing the simulated blood vessel can be carried out on this vascular anastomosis training operation table.

[0026] (4). When performing vascular anastomosis training, the distance of the anastomosis of the simulated blood vessel 9 can be adjusted by adjusting the rotating handle 7.2 of the lead screw 7 to facilitate the operation training. After one operation is completed, the rotating handle 7.2 of the lead screw 7 can be adjusted to shorten the distance between the left flat-tip needle 3 and the right flat-tip needle 8, cut short the simulated blood vessel 9 to remove the anastomosis of one operation and then use it again. Repeating this way, the simulated blood vessel 9 can be utilized to the maximum extent and the consumables can be saved.

[0027] (5). After each training is completed, the conduction condition of the vascular anastomosis can be evaluated by counting the flow rate of the incoming and outgoing liquids, and the airtight condition of the vascular anastomosis can be objectively evaluated by monitoring the leakage condition of the anastomosis.

[0028] (6) By replacing the left flat-ended needle 3 and the right flat-ended needle 8 with different calibers and simultaneously matching with the simulated blood vessels 9 of the corresponding calibers, it is possible to simulate blood vessels of different sizes for training.
