Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of device that is applied to multi-angle fixed traction line in single hole thoracoscope Wicresoft pulmonary surgery.
Background technology
Thoracoscopic operation is carried out in early 1990s, through vicennial development, has been widely used in diagnosis and the operative treatment of thoracic surgery various diseases at present.Wherein thoracoscope lobectomy of lungs treatment I, II phase nonsmall-cell lung cancer and lung benign lesion, its safety and efficacy is affirmed to have the advantages such as wound is little, recovery is fast, postoperative pain is light, shoulder connecting portion function effect is little.Thoracoscope has identical Wicresoft's effect too aspect the treatment of pulmonary's benign disease.
The course that thoracoscope pulmonary surgery approach has experienced thoracoscopic operation, three holes, single operation hole (two holes), single hole (unique hole) under auxiliary incision changes, more and more Wicresoft, become more meticulous.Having reached at present single hole at the thoracic surgery center of minority is under unique hole, to carry out pulmonary surgery operation under thoracoscope, has further reduced otch quantity, has alleviated postoperative pain, has reduced operation wound, has embodied the huge superiority of Wicresoft.
But because the operation otch of single hole thoracoscope pulmonary of Wicresoft position operation is fixed and unique, be subject to the restriction of incision site and size, there is many drawbacks, the links of impact operation: first, thoracoscope and various operating theater instruments must pass in and out jointly from unique hole, and the angle that operates various apparatuses in art is often collided limited each other; The second, viewing angle is limited, and open chest surgery or three hole thoracoscopic operations can expose to all directions tractive lobe of the lung position and the structure of required understanding, and under single hole thoracoscope, operation just cannot so be followed one's bent; The 3rd, for cutting off, blood vessel and bronchial angle are more single, cannot resemble three hole thoracoscopies or open breast from suitable angle through target, then cut off; The 4th, carry out bronchovascular resection under single hole time to the fixing difficulty of draught line, for example, when the formula of tucking inside the sleeve resection and anastomosis is bronchial, coincide if adopt to be interrupted, various knotting lines fixedly can not get good arrangement, tend to tied up in knots each other, the carrying out of impact operation, even coincide unsuccessfully.
Above drawback causes the difficulty of thoracoscope pulmonary surgery under single hole to increase; only just can be completed by veteran doctor at veteran thoracic surgery center; how to solve these drawbacks; make thoracoscope Minimally Invasive Surgery operation under single hole push domestic grass-roots unit to, better benefiting patient becomes problem in the urgent need to address.
Summary of the invention
For the operating defect of single hole, need to design special apparatus and explore special operation skill and can address the above problem, the lymph node biopsy pincers that for example design pulmonary traction pliers, the dragline type of dragline type solve that the apparatus gateway of causing in single hole is blocked, collision phenomenon mutually; For example special skill: adopt draught line to overlap blood vessel, bronchus in operation, be beneficial to passing of cutting device to different direction tractives, guarantee the corresponding structure of safe cut-out; For example in blood vessel bronchus is rebuild, the ingenious of draught line fixed.But in the design of above-mentioned all solution single hole operating defects, all relate to the processing of numerous draught lines, and how to make the relation of these draught lines in order, be unlikely to allow numerous draught lines mutually tangle, be knotted into for primary problem; Direction of draw angle how to adjust draught line has also directly affected whether well visual area exposes, whether smoothly cutting device passes target texts.Therefore this utility model provides the draught line fixture in a kind of single hole thoracoscope pulmonary Minimally Invasive Surgery, and it can make the relation of draught line in order, adjusts the orientation angle of draught line.
This utility model provides a kind of draught line fixture being applied in single hole thoracoscope Wicresoft pulmonary surgery, and it comprises U-shaped becket and the telescoping tube of Metallic rod, intervallum spring; One end of the U-shaped becket of intervallum spring is connected with Metallic rod by the first connector, and the other end is connected with telescoping tube by the second connector, and telescoping tube is made up of more than 2 hollow pipe; Head and the tail end of its adjacent hollow pipe are socketed successively; The terminal position of hollow pipe arranges plastic hook.
The U-shaped becket of intervallum spring refers to by multiple springs successively interval and connects the many U-shaped beckets that metal tube forms, it is interrupted respectively the multiple springs of configuration between the semi-circular structure of U-loop, so both can guarantee the semi-ring form of U-loop, make this device meet intrathoracic structure, be just in time stuck in thoracic cavity; Ensure again certain elasticity, suitably enlarge bolt interval, conveniently inserts thoracic cavity.
In this utility model, the tail end of described Metallic rod arranges annulus, facilitates tractive, contributes to this device relatively fixing in thoracic cavity.。
In this utility model, described the first connector and the second connector are alligator clamp structure.
The first connector is alligator clamp structure, this fixture is outside thoracic cavity time, make Metallic rod with annulus take the alligator clamp structure of this connector as axle, acutangulate and stick together with above-mentioned U-loop the first half, need to insert in thoracic cavity time, need artificially Metallic rod firmly to be equalized, insert rear relieving, the effect of alligator clamp makes thoracic wall clamping outside Metallic rod and thoracic cavity, is able to device relatively fixing in thoracic cavity.
The second connector is alligator clamp structure, this fixture is outside thoracic cavity time, make telescoping tube take the alligator clamp structure of this connector as axle, acutangulate and stick together with above-mentioned U-loop the latter half, need to insert in thoracic cavity time, need artificially effective plastic hollow power to be equalized, insert rear relieving, the effect of alligator clamp makes thoracic wall clamping in plastic hollow pipe and thoracic cavity, is able to device relatively fixing in thoracic cavity.
The beneficial effects of the utility model are: its apparatus structure is simple; be skillfully constructed; can make draught line in order; prevent that numerous draught lines is wound around mutually, it can adjust the orientation angle of draught line simultaneously, facilitates the exposure of visual area; it makes the cutting device in thoracoscopic lobectomy of lung under single hole can pass smoothly target; perform the operation more simple, more easily move towards basic unit, benefit patient.
