Abstract
Description
Technical Field
[0001] The invention relates to the technical field of surgical instruments, and in particular to a myocardial annular electric knife cutting system. Background Art
[0002] Hypertrophic cardiomyopathy is a common dominant hereditary disease with a prevalence of about 0.2-0.5% in the general population, of which about 70% require surgical treatment. Currently, the main surgical method is ventricular septal myectomy, which removes the hypertrophic myocardium, relieves left ventricular outflow tract stenosis and pressure difference, and restores heart function.
[0003] At present, the scalpels commonly used for ventricular septal myocardectomy in clinical practice are traditional sharp knives or small round knives. The main problem lies in the efficiency of the myocardial resection process, and it is not possible to remove the hypertrophic myocardium smoothly and efficiently. On the other hand, the myocardium removed by traditional scalpels is often in fragments, which significantly increases the operation time and extracorporeal circulation time, and also increases the risk of embolic events such as cerebral infarction caused by the lost myocardial fragments after the operation. In addition, traditional scalpels are sharp structures, which may damage the normal heart tissue structure during the process of entering and exiting the knife, increasing the risk of iatrogenic trauma. Finally, due to the length of the knife handle, it is currently impossible to perform surgical resection on patients with apical hypertrophy through a single aortic incision into the left ventricle.
[0004] Currently, some surgeons choose to use electric knives for cutting. However, the traditional electric knife head is linear and cannot control the cutting angle and depth well. In addition, since the electric knife head is relatively flexible, it may cause deformation of the knife head during the cutting process, affecting the progress of the operation. Summary of the invention
[0005] The main purpose of the present invention is to provide a myocardial annular electrosurgical cutting system to solve the above problems.
[0006] To achieve the above-mentioned purpose, the present invention provides a myocardial annular electrosurgical cutting system, comprising a detachably connected handle and a blade head; the handle comprises a hard hand-held portion and a plastic transition portion; one end of the hard hand-held portion is connected to the blade head, and the other end is connected to the plastic transition portion; the hard hand-held portion is provided with an electrosurgical control button and a light source and lens of an illumination imaging system; the main body of the blade head is in the shape of a hollow circular ring, and the electrosurgical control button is electrically connected to the hollow circular ring-shaped main body.
[0007] Furthermore, a connecting rod is provided on one side of the hollow circular main body, and a handle connecting buckle is provided on the connecting rod; a blade connecting buckle is provided on the end of the hard hand-held part away from the plastic transition part; the handle connecting buckle is connected with the blade connecting buckle.
[0008] Furthermore, an electrosurgical system connecting line and an illumination and imaging system connecting line are provided at one end of the plastic transition portion away from the hard handheld portion; the electrosurgical system control button is electrically connected to the electrosurgical system via the electrosurgical system connecting line; and the light source and lens of the illumination and imaging system are electrically connected to the illumination and imaging system via the illumination and imaging system connecting line.
[0009] Furthermore, the cutter head has multiple models.
[0010] Furthermore, the cutter head has three types, and the inner diameters of the main bodies are 5 mm, 10 mm and 15 mm respectively.
[0011] Furthermore, the knife handle has two models, and the lengths of the hard hand-held part are 30 cm and 50 cm respectively.
[0012] Furthermore, the hard handheld part is provided with an absorber connecting tube, and one side of the cutter head is provided with an absorber opening, and the absorber opening is connected to the absorber through the absorber connecting tube.
[0013] The present invention has the following beneficial effects:
[0014] 1. Compared with traditional scalpels, the use of electric knife can significantly improve the efficiency of myocardial resection and reduce the operation time;
[0015] 2. Electrosurgical resection will not produce tissue fragments, reducing the occurrence of postoperative embolic events;
[0016] 3. By designing a longer handle and different inner diameters of circular electrosurgical blades, it is possible to perform surgery on patients with long hypertrophy involvement and hypertrophy involving the apex, fully ensuring the length and depth of the surgical resection and reducing the use of apical incisions;
[0017] 4. The design of the ring-shaped electrosurgical knife can ensure that the electrosurgical knife head is stable and does not deform, while allowing the surgeon to easily adjust the depth and angle of the knife at any time according to the intraoperative situation and personal experience, so that the surgeon can clearly determine the depth and range of resection, increase the surgeon's control over the operation, and reduce the incidence of iatrogenic ventricular septal perforation;
[0018] 5. Due to its compatibility with the lighting imaging system, the circular electrosurgical unit can also be used for thoracoscopic ventricular septal myocardectomy;
[0019] 6. Compatible with the suction module, the present invention can conveniently absorb the smoke and finely chopped tissue blocks generated by electrosurgical cutting during surgery. BRIEF DESCRIPTION OF THE DRAWINGS
