Description
Technical field
The present invention relates to a kind of operating theater instruments, particularly relate to a kind of operation on urinary system or various initiative, minimally heart surgery, also have non-invasive routine inspection.
Background technology
Along with the development of science and technology, the apparatus in modern surgical operation also gets more and more, and operating theater instruments can well help doctor to complete operation, improves convenience and safety.At present, independent flexible ureteroscope and rigid ureteroscope is had respectively in the world.Rigid ureteroscope is easy to operate, conveniently can arrive renal pelvis by ureter, as Chinese patent: " a kind of Combined rigid ureteroscope (CN201929938U) ", comprise rigid ureteroscope body and be sleeved on the tubulose mirror sheath outside mirror body tube, fit tightly between the initiating terminal of mirror sheath and described mirror body tube, the rear end of mirror sheath is provided with retaining mechanism, be provided with tight lock part between mirror body tube and operating portion, retaining mechanism matches with described tight lock part and rigid ureteroscope and tubulose mirror sheath is locked or are got loose.But due to the inflexibility of rigid ureteroscope front end, direction can not be regulated after it enters renal pelvis to enter each group of renal calices and to carry out various Diagnosis and Treat; Although flexible ureteroscope front end unidirectional or multidirectional wide-angle can bend, turns to, be difficult to enter renal pelvis and renal calices through ureter, although renal pelvis and renal calices can be entered under the guiding of x-ray, x-ray to doctor and patient trauma larger.For the Main way that the ureteroscope having soft and rigid performance concurrently is research and development now.
Summary of the invention
The invention provides a kind of structure simple, have the advantage of soft lens and rigid scope concurrently, and can bend the apparel construction adapted in kidney, easy to use, safety is high, greatly alleviates the ureteroscope of patient's pain of injury; Solve the ureteroscope that exists in prior art or be soft or be rigid scope, the technical problem of malfunction.
Above-mentioned technical problem of the present invention is solved by following technical proposals: a kind of ureteroscope, comprise mirror pipe, mirror pipe is connected with mirror tube body, imaging system and illuminator is provided with in mirror pipe, imaging system connects with the observation section on mirror tube body, illuminator connects with the Lighting Division on mirror tube body, it is characterized in that: described mirror pipe comprise connect successively end head, bending section and insertion section, the end of insertion section is connected with mirror tube body, described insertion section is soft mirror pipe, and mirror tube body is provided with the bending operation portion controlling bending section; In mirror pipe, be provided with first passage, in mirror tube body, be provided with second channel, first passage is communicated with second channel and forms multiplex passage, in multiplex passage, be provided with dismountable support bar or operating theater instruments.When the multiplex passage that first passage and second channel are formed, one end of multiplex passage is opened in the end head of mirror pipe, the other end of multiplex passage is opened on mirror tube body, in multiplex passage during grafting support bar, due to the bar that support bar is rigid, when support bar is positioned at mirror pipe, mirror pipe becomes hard tube, possess enough rigidity and toughness, be conveniently inserted in kidney.Due to human kidney complex structure, now support bar can be exited by mirror pipe, mirror pipe loses rigidity and the toughness of support bar, become flexible pipe, mirror pipe now utilizes bending operation portion to control the bending of mirror pipe according to kidney Nei Zhi road again, meets operation and uses needs, when finding the position needing operation, can in multiplex passage insertion instrument, multiplex passage now uses as instrument channel.Thus to achieve ureteroscope both can be soft lens also can be hard mirror, according to no operational phase, selected different hardness.Simple to operate, use safety.Soft mirror pipe refers to that mirror pipe is soft, can adopt the manufacture of the material such as medical polyurethane or medical PU.
The optical frames imaging system of imaging system can be fibre scope imaging system also can be prism composition or all the other known imaging systems, same illumination channel can adopt cold light source or light guide bundles form or all the other known forms.As preferably, described imaging system comprises the imaging band be arranged in mirror pipe, image transmission optical fibre is provided with in imaging band, imaging band is connected with the observation panel on mirror tube body, described illuminator comprises the illumination channel be arranged in mirror pipe, in illumination channel, be provided with optical fibers, illumination channel is connected with the light guide bundles interface on mirror tube body.Illumination channel is two both sides being positioned at imaging band, better for imaging band throws light on, imaging can be made more clear, facilitate operator to perform the operation.
As preferably, the end of described support bar is provided with Access Division, the card-tight part coordinated with Access Division is provided with in the end of mirror tube body, described Access Division comprises a kidney-shaped card adapter plate, Access Division offers draw-in groove, described card-tight part is provided with the mounting hole coordinated with Access Division, is provided with the projection coordinated with draw-in groove, outside card-tight part, is provided with set lever in the upper end of mounting hole.Be provided with Access Division support bar and mirror tube body fixed in the end of support bar, when support bar is inserted in multiplex passage, support bar and mirror tube body can be locked, then form rigid ureteroscope, convenient and swift during operation.After card-tight part coordinates with Access Division, rotational lock handle, because draw-in groove and protruding cooperation make both locking.
As preferably, the two ends of described bending section are connected with end head and insertion section respectively by adapter ring, bending section is made up of snake bone and the bending skin be socketed in outside snake bone, cable wire solderless wrapped connection fixture is provided with in one end that bending section connects with end head, on cable wire solderless wrapped connection fixture, solderless wrapped connection has cable wire, and two free ends of cable wire are fixed in bending operation portion.Snake bone structure is simple, flexibly bending, handled easily, and by bending operation, portion pulls cable wire, thus drives bending section angle of bend, adapts to the labyrinth requirement in kidney.
As preferably, described bending operation portion comprises thumb wheel, and thumb wheel is connected with cable wire fixture, cable wire fixture is fixed with two free ends of cable wire, cable wire fixture is fixed on slide, and slide is positioned at mirror tube body, is provided with locking connector between thumb wheel and cable wire fixture.Thumb wheel band running wire kinematic mount, thus pull the two ends of cable wire, the closing end of cable wire is fixing on the bends, by pulling the free end of cable wire, controls the angle of bend of bending section.
As more preferably, described cable wire fixture comprises top shoe and sliding block, the outer surface of slide connects with the inwall of mirror tube body, dead axle is provided with at the center of the side of slide, two installed surfaces be parallel to each other are offered in the both sides of dead axle, top shoe and sliding block lay respectively on installed surface, and upper and lower slide block is fixed with the end of cable wire; Dead axle is socketed with thumb wheel and interiorly takes turns, interior wheel is provided with two shifting blocks, and two shifting blocks are positioned at the two ends of taking turns same diameter, and upper and lower slide block offers fluting, slot with installed surface to offer direction vertical.Two shifting blocks of inside taking turns lay respectively on top shoe and sliding block, by the interior rotation taken turns, make sliding block adverse movement on take-up housing, thus pull the two ends of cable wire to allow bending section bend an angle, meet the requirement of operator.
