Description
Technical Field
The utility model relates to the field of vascular suturing, in particular to a novel vascular connector assembly for 3D printing.
Background
3D printing (Three Dimensional Printing) is a rapid prototyping technology, the principle is that powder plastic or metal and other adhesive materials are utilized, layering is carried out according to a certain thickness through layering software according to different process requirements by a three-dimensional solid model, so that a three-dimensional digital model is converted into a plurality of two-dimensional plane models with very thin thickness, then certain processing is carried out on the data, processing parameters are added, numerical control codes are generated, each thin layer is continuously processed in a plane processing mode under the control of a numerical control system, and the thin layers are bonded to form the technology of forming a real object.
With the rapid development of society, economy and science, vascular lesions caused by various diseases and vascular trauma caused by various external causes are becoming more common, and emergency operation is often required for vascular repair or vascular anastomosis. The vascular suturing technique is one of basic skills and necessary skills of vascular surgeons, but the success rate of vascular suturing is increased by more repeated training, sometimes the successful suturing is not satisfactory without blood leakage, 1 or more remedial suturing hemostasis is needed, sometimes the vascular injury at the anastomotic site is aggravated, the suturing is failed, and the suturing is needed to be carried out after the reconditioning. The blood vessels spread over the whole body, some blood vessels are deep, and the exposure operation is not easy, so that the anastomosis difficulty is increased. An excessively long anastomosis time during surgery means an excessively long ischemia time of the distal tissue, resulting in tissue cell ischemia necrosis and a more serious ischemia reperfusion injury after patency. These problems have been plagued vascular surgeons, and have also threatened the life safety of the patient, affected the recovery time of the patient, increased the number of hospitalization days and the cost of surgery, etc.
At present, the problem needs to be solved urgently, the improvement of the suturing technology is a method, but long-term repeated exercise is needed, the learning period is long, the grasping degree of each doctor is different, and the suturing completion degree is not stable enough. If a connecting device is used for anastomosing blood vessels simply and conveniently, the study difficulty is low, the time period is short, the suture stability is strong, the operation time and the remote tissue ischemia time can be greatly reduced, the success rate of the operation is improved, the operation complications are reduced, the quick recovery of patients is promoted, the hospitalization time is shortened, the hospitalization cost is reduced, and the medical insurance burden is lightened.
Disclosure of utility model
The utility model aims to provide a novel 3D printing vascular connector assembly so as to solve the problems that the existing vascular suturing operation is difficult and the suturing completion degree is unstable.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a novel vascular connector subassembly is printed to 3D, includes communicating pipe and solid fixed ring, communicating pipe has the intercommunication mouth more than two, is close to the tip of intercommunication mouth all has and is used for installing gu fixed ring's annular protrusion.
Preferably, the communicating pipe is of a straight pipe structure and is provided with two communicating ports.
Preferably, the communicating pipe is of a three-way pipe structure and is provided with three communicating ports.
Preferably, the diameter of the annular protrusion is 1mm larger than the diameter of the communication port.
Preferably, the width of the fixing ring is 1mm, and the inner diameter is equal to the diameter of the annular protrusion.
Preferably, the communicating tube and the fixing ring are prepared in a 3D printing mode.
The principle and beneficial effect of this technical scheme:
The outer wall of the vessel communicating vessel is equal to the diameter of the inner wall of the vessel, the port of the communicating vessel can be conveniently inserted into the fracture of the vessel, the annular bulge is wrapped by the elasticity of the vessel by a circle slightly larger than the vessel to prevent blood from overflowing, the fixed ring with the equal diameter of the inner diameter and the annular bulge is matched with the annular bulge, the communicating vessel can be well prevented from falling off to fix the vessel, because the operation of simply sleeving and moving the fixed ring is simple, the technique can be mastered by simple exercise, the requirement on a vessel suture doctor can be reduced, the completion degree is improved, the labor cost is reduced, and more patients can be healed.
