Description
Technical field
The utility model is related to a kind of medicine equipment for taking out calculus in human body, and specifically a kind of step-by-step movement is medical to be taken
Stone implement.
Background technology
It can use Minimally Invasive Surgery will be internal for kidney stone, the urethral calculus that can not be excreted using drug therapy
Calculus is taken out, and this minimally invasive stone dislodger for taking stone operation to use has two kinds：Lithotomy forceps and stone basket.Both differences are that the former adopts
Clamp calculus with binding clip and basket that the latter is constituted using many one metal wires extracts calculus, both common ground be its operating portion all
Be use be arranged on flexible pipe in can pull flexible shaft operation binding clip or basket action.Due to the small volume of binding clip or basket,
The scope and amplitude of motion are smaller, and direct pull flexible shaft operation is difficult to be accurately positioned, and excessive easily cause of movement range takes stone to lose
Miss, or even accidentally injure tissue.Chinese patent 2009203062998 discloses one kind《Claw-shaped stone extractor》, using scissors shank type
Operation handle, using the lever construction pull flexible axle being hinged, its movement range is adapted to artificial operation.But due to scissors shank type
Articulated structure itself there is larger error gap, and do not have to receive different resistances in lock function, operation in action process
Easily formation action shakes, takes the phenomenons such as stone landing for the influence of power, and the stability of action has much room for improvement.
The content of the invention
The purpose of this utility model is to provide a kind of accurate exquisiteness of simple in construction, easy to use, action, stability is good, subtract
The medical stone dislodger of step-by-step movement slipped up less.
The utility model is to solve the technical scheme that is used of technical problem：
The medical stone dislodger of step-by-step movement described in the utility model includes outer tube, the control stick being inserted into outer tube, sets
The stone extraction basket controlled in the lower end of outer tube and manipulated bar, the upper end of the outer tube is provided with stepping pusher, institute
Stating stepping pusher includes being fixedly connected on the handle of outer sleeve upper, the handwheel on handle and screwed pipe, the hand
Handle is by the train wheel bridge be arrangeding in parallel, lower plate and is fixedly connected on the framework that the side plate at train wheel bridge and lower plate two ends is constituted
It is fixedly installed on the connecting tube for accommodating overcoat tube end, train wheel bridge and lower plate and sets on structure, the lower surface of the lower plate
It is equipped with through hole, the through hole is coaxially disposed with connecting tube and the diameter of through hole is less than the internal diameter of connecting tube, described to pass through
The projection of oriented axis direction extension is set on the inwall of perforation, and the screwed pipe is slidably mounted in through hole, screwed pipe
Carried on outer wall on groove that is axially arranged and matching projection, the outer wall of screwed pipe and be provided with external screw thread, existed by thread set
Handwheel on screwed pipe is located in the space between train wheel bridge and lower plate, and the upper end of control stick inserts and is fixedly connected on screw thread
In the inner chamber of pipe.
After adopting the above technical scheme, the stone dislodger uses the stepping mechanism pull flexible axle that screw thread is pushed, its is simple in construction,
The accurate fine and smooth, stability of easy to use, action is good, takes stone one-time success rate high, advantageously reduces surgical error.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is Fig. 1 A-A sectional views.
Fig. 3 is Fig. 1 B-B sectional views.
Embodiment
As shown in figure 1, the medical stone dislodger of step-by-step movement described in the utility model includes outer tube 1, is inserted into outer tube 1
Control stick 2, the stone extraction basket 3 that the lower end and manipulated bar 2 for being arranged on outer tube 1 are controlled, outer tube 1 and control stick 2 are adopted
It is made of flexible materials such as silica gel, plastics, flexible and have certain elasticity, the opening and closing of stone extraction basket 3 when pull control stick 2
Action, captures and catches calculus, then taken out with outer tube 1.The upper end of the outer tube 1 is provided with stepping pusher,
The stepping pusher includes being fixedly connected on the handle of the upper end of outer tube 1, the handwheel 5 on handle and screwed pipe 6, institute
It is by the train wheel bridge 41 be arrangeding in parallel, lower plate 42 and the side for being fixedly connected on train wheel bridge 41 and the two ends of lower plate 42 to state handle
The connecting tube 7 for accommodating the end of outer tube 1 is fixedly installed on the frame structure that plate 43 is constituted, the lower surface of the lower plate 42,
Be provided through hole on train wheel bridge 41 and lower plate 42, the through hole be coaxially disposed with connecting tube 7 and through hole diameter
Less than the internal diameter of connecting tube 7, the projection 8 of oriented axis direction extension is set, the projection 8 has two on the inwall of the through hole
Block, axle center is symmetricly set on the inwall of through hole.The screwed pipe 6 is slidably mounted in through hole, on the outer wall of screwed pipe 6
With axially arranged and match the groove of projection 8, projection 8 is located in the groove of screwed pipe 6, is provided with the outer wall of screwed pipe 6
External screw thread, the internal diameter of through hole is more than the external diameter of screwed pipe 6, while the gap between the top of two projection 8 is less than the outer of screwed pipe 6
Footpath but the internal diameter for being more than screwed pipe 6, make projection 8 to be stuck in just in the groove of screwed pipe 6 and be unlikely to used and wear screwed pipe 6
Tube wall.
As shown in Figure 2 and Figure 3, by handwheel 5 of the thread set on screwed pipe 6 be located at train wheel bridge 41 and lower plate 42 it
Between space in, internal thread is provided with handwheel 5, the upper end of control stick 2 inserts and is fixedly connected in the inner chamber of screwed pipe 6.
In use, rotating handwheel 5, it is set to be moved axially on screwed pipe 6, the upper and lower due to handwheel 5 is to having train wheel bridge 41 and lower folder
