Description
Technical field
The invention belongs to medical endoscope auxiliary facilities field, especially relates to mechanical grip mechanism of a kind of lightweight endoscope.
Background technology
Endoscope is a pipe being equipped with light, and it can enter gastric or enter in body through other natural hole by direct oral cavity.Utilize endoscope to see in the diagnosis and treatment of routine, be therefore widely used the pathological changes that X-ray can not show.Along with the development of endoscope and the demand of Minimally Invasive Surgery, the stereo endoscope that can manifest 3-D view obtains increasing application.Stereo endoscope, as intervention means new in medical diagnosis applications, in use to inside of human body three-dimensional imaging, can provide sufferer information more accurately for doctor, avoid the maloperation of surgical.Stereo endoscope is compared with conventional endoscope, and owing to adding more optical element and image processing elements, therefore weight has a larger increase.In current operation process, endoscope manually holds mirror by medical personnel to operate, when the major surgery that the time that runs into is longer, hold mirror work for a long time can make to hold mirror personnel and produce feeling of fatigue and occur holding the situation of mirror shakiness, now just need replacement to hold mirror personnel, otherwise just can affect operation observing effect.
Chinese patent " endoscope clamping manipulator " (publication number 102293626A) proposes a kind of endoscope clamping manipulator structure, comprises horizontal rotary mechanism, luffing mechanism, elevating mechanism and free-wheeling system.By the operation of control system, the adjustment of endoscope's four degree of freedom can be realized, instead of manual operation.But there are the following problems in this invention:
1, device structure arranges too complicated:
1), relate to Self-rotation structure in this patent, by gear driven, endoscope completes rotation.But along with the improvement of this body structure of endoscope, turn increase such as Inlet and outlet water valve component, outer fiber passage etc., cause endoscope's overall volume to increase, outside line increases.Now carry out rotation again and will relate to more exterior line, it is very inconvenient to use.On the other hand, endoscope is through improvement in a few years, and the concordance that part is observed in its front end is higher, therefore no longer needs from transferring further adjustment.
2), in this patent elevating mechanism, luffing mechanism, horizontal rotary mechanism respectively adopt a motor and speed reducer assembly, cause Whole Equipment parts too much.On the other hand, above-mentioned adjustment can not be carried out simultaneously, and therefore arranging too much motor also can increase equipment cost and damage probability.
2, instrumentation space is little:
Pitching yaw in this patent and control motor device thereof are placed in circular base, cause in circular base for the space that other medical apparatus and instruments are reserved is less.When to need 3 kinds or more surgical apparatuses to operate simultaneously simultaneously, just can be restricted because operative space is little.
3, device security protectiveness is poor:
As can be seen from description and the accompanying drawing of this patent, the leading screw of its elevating mechanism and attached gear etc. thereof are all outside exposed, and the growth along with service time just can overstock dust, not easy to clean.Simultaneously once be infected with other pollutant such as body fluid, also descending operation performance can be affected.On the other hand, the driven gear in horizontal rotary mechanism is also naked being exposed on the external, and clamps other objects possibly in its rotation process, once clamp the pipeline of other armarium, consequence is hardly imaginable.
Summary of the invention
The problems such as the problem that the invention will solve is, provides mechanical grip mechanism of a kind of lightweight endoscope, and can solve the device structure existed in prior art complicated, apparatus headspace is little, security protection difference.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is:
Mechanical grip mechanism of a kind of lightweight endoscope is provided, comprises chassis, horizontal rotary mechanism and lifting luffing mechanism; Described horizontal rotary mechanism is positioned on chassis, and described lifting luffing mechanism is bearing in the edge of horizontal rotary mechanism; Described horizontal rotary mechanism comprise be connected with chassis by bearing annular rotary table, to be positioned at annular rotary table inner and be installed on gear wheel on bearing, with the pinion of gear wheel engaged transmission and horizontally rotate motor; Described lifting luffing mechanism comprises motor controling part, lifting unit and pitching portion; Described motor controling part comprises lifting pitching motor and Worm and worm-wheel gearing, endoscope's holding ring that described lifting unit comprises the leading screw be connected with described Worm and worm-wheel gearing, the leading screw outer tube being wrapped in leading screw outside and is connected with leading screw; Described pitching portion comprises pitching base and is positioned at the worm sector of chassis interior, and worm sector is connected with described Worm and worm-wheel gearing simultaneously; Described each mechanism is all electrically connected with the control system controlling each mechanism action.
Further, described lifting luffing mechanism is supported on the edge of described annular rotary table, and can with annular rotary table horizontally rotate and synchronous axial system.
Further, described bearing adopts ceramic balls.
Further, described control system is adjust the sound control regulator of each mechanism action or the Multifunctional pedal device by each mechanism action of foot-operated control adjustment by Voice command.
Further, described control system comprises the sensing mechanism be located in described each mechanism and each sensing mechanism is sent the device that signal processs and displays.
The advantage that the invention has and good effect are:
1, hand mirror operation can be substituted, save human cost, avoid the malpractice that tired operation causes simultaneously.
2, adopt leading screw as elevating mechanism, instead of the rack-and-pinion of overseas equipment, the motion mode of its helical rotation steadily and can realize self-locking, to be avoided in operation, because deadweight causes sight glass change in location, also can preventing because of power-off or the other reasons danger making sight glass drop suddenly out of control.Leading screw is wrapped in leading screw outer tube simultaneously, laying dust can be avoided or by humoral pollution.
3, elevating function and pitching function adopt same group of motor and worm and gear assembly to control, and greatly reduce equipment volume and device fabrication cost, reduce device damage probability simultaneously.
4, be elevated luffing mechanism and the Electric Machine Control part that horizontally rotates is positioned at annular rotary table ipsilateral penumbra, the farthest space of release circular disk, reserve larger working place for other operating theater instruments participate in operation.
5, the gear wheel in horizontal rotary mechanism is placed in annular rotary table inside, avoids the danger be involved in by other armarium pipelines in rotary course in exposed situation outside.Bearing simultaneously in horizontal rotary mechanism have employed ceramic balls, difficult drop-off, not easily gets rusty simultaneously.
6, pitching function drives endoscope to realize by worm gear, and we consider the needs of luffing angle in practical application here, are made by worm gear fan-shaped, thus ensure that minimizing of pitching base volume, further reduce the volume of whole clamping device.Worm sector can realize the self-locking in endoscope's pitching process simultaneously, avoids the endoscope occurring controlling because of power-off or equipment fault appearance to topple over danger.
7, the invention also can be provided with sound control regulator, and operative doctor with language commander adjustment or can change sight glass position;
8, the invention also can be provided with Multifunctional pedal switch, can be controlled adjustment by foot-operated or changed sight glass position, eliminates in operation and operates doctor and the inconvenience of holding mirror doctor and linking up;
