Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is used to excise the medical operation suction cutter of nasal polyp and paraphyte in a kind of specifically nasal sinuses videoendoscopic surgery.
Background technology
The medical apparatus and instruments of special use is a medical operation suction cutter when carrying out the nasal polyp resection operation at present under nasal endoscope.At present the employed medical operation suction cutter of hospital since exist can not autoclave sterilization, apparatus gets rusty easily, normal saline and defectives such as the turnover from same conduit of excision thing, trivial operations, not only cause the cross infection of pathogenic bacteria easily, motor is short service life, doctor's labor intensity increases, operating time prolongs, and wound surface is wayward, main is that patient's bleeding is many, pain is strong, increases the fear to operation, causes affecting adversely the early treatment.
The utility model content
At above-mentioned deficiency of the prior art, this utility model provides a kind of medical operation suction cutter, both but autoclave sterilization, apparatus were difficult for getting rusty, motor long service life, normal saline pass in and out from different conduits with the excision thing, make again cut coverage be easy to control, simple to operate, get a clear view, go out advantage such as insufficiency of blood.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of medical operation suction cutter comprises main body, is assemblied in toolbox, electric machine assembly that is connected with main body and the connection controller that links to each other with motor on the main body.
Described main body comprises engagement coupling assembly, transmission component, holds knife assembly and feed liquor Control Component.In the engagement coupling assembly engaging-piece cover, engaging-piece spring and engaging-piece bearing (taper) are arranged, partly insert motor in the main body, opening power, motor rotates and drives planetary reduction gear, by planetary reduction gear moment is passed to the engagement coupling and partly drive travelling gear in the transmission component, travelling gear is connected in to connect on the hollow splined shaft and has driven the transmission component part, cutter rotated and starts working in transmission component made, and the engaging-piece telescopic spring is realized the engagement between motor part and the engaging-piece bearing.Be characterized in the installation of described motor and planetary reduction gear in the enclosure, the output of decelerator connects engagement component.Motor and main body are split-type structural, when sickle uses, motor are inserted in the main body; During sterilization, motor is taken out in main body, need not carry out disinfection, avoid motor and decelerator to get rusty, be corroded, ensure patient safety, health, prolong the service life of motor and decelerator, reduced the repair rate of sickle motor and decelerator.
Described medical operation suction cutter, motor housing be provided with a hasp and with the step of snap fit, when motor inserted main body, the engaging-piece spring was compressed, hasp is stuck on the step automatically.When motor takes out in main body, push hasp, hasp breaks away from step, and the elastic force of engaging-piece spring outwards moves motor, can take out, and loads and unloads very convenient, fast.
Described medical operation suction cutter, feed liquor is spigot joint to be provided with on controller towards liquid pump, press feed liquor control handgrip, promote the feed liquor control spring, open the passage of feed liquor on spigot joint, normal saline just from feed liquor spigot joint by interior cutter outer wall and outside space between the cutter inwall enter in the body cavity and clean.After cleaning finished, sewage pipe in the interior cutter excreted through discharge opeing is spigot joint.Be characterized in that input duct separates with Drainage pipe, prevent the courses of infection normal saline in the drain, the Drainage pipe space is bigger than input duct space simultaneously, blocking pipe when preventing that cut substrate from discharging.
Described medical operation suction cutter, when travelling gear was worked in the transmission component, the flexible promotion of automatic adjuster spring sealing ring can be regulated the gap between the cone bearing automatically, plays sealing function, prevents discharge liquor access instruments inside, causes that apparatus gets rusty, corrodes.
Described medical operation suction cutter, hold knife assembly and be made up of lock cutter spring, lock cutter gland and lock cutlery-type stainless steel pearl etc., pin lock cutter gland toward pusher, lock cutter spring is compressed, lock cutlery-type stainless steel pearl glides, and selects suitable cutter to insert and holds in the knife assembly.After treating that cutter inserts, unclamp lock cutter gland, lock cutter spring is replied, and cutter can use.
Adopt technique scheme, the beneficial effect that brings to this utility model is: but autoclave sterilization, soaking disinfection, rotating speed height, be difficult for getting rusty, simple to operate, get a clear view, cut coverage is easy to control, go out characteristics such as insufficiency of blood, for medical industry provides a novel operation sickle.

The specific embodiment
Below by embodiment, and, the technical solution of the utility model is described in further detail in conjunction with Figure of description 1.
Medical operation suction cutter, comprise main body 4, can insert main body electric machine assembly 23, be assemblied in the toolbox 28 on the main body.Electric machine assembly 23 is built-in with motor 1 and the planetary reduction gear 13 that is connected with motor 1.Main body comprise engagement coupling assembly 24, with mesh transmission component 25 that coupling assembly 24 matches, be connected with transmission component 25 hold knife assembly 26 and feed liquor Control Component 27.Pressing hasp 2 will mesh with engagement coupling assembly 24 in the electric machine assembly 23 insertion main bodys 4.Engagement coupling assembly 24 comprises that the engaging-piece that is engaged on planetary reduction gear 13 output shafts overlaps 14, overlaps 14 engaging-piece spring 15 that is connected and engaging-piece bearings 16 with engaging-piece.Travelling gear 5 loose joints in engaging-piece bearing 16 and the transmission component 25, travelling gear 5 interconnects with bearing 6, travelling gear 5 leading portions are fixed in and connect on the hollow splined shaft 7, and travelling gear 5 rotates to drive and connects hollow splined shaft, and cutter 21 left-right rotation are started working in making.Automatic adjuster spring 9 freely stretches and makes cone bearing 8 regulate the gap automatically, makes sealing ring 17 sealings simultaneously, prevents to excise the thing pollution and stops up apparatus and pipeline.Hold knife assembly 26 and comprise lock cutter spring 10, lock cutter gland 11 and lock cutlery-type stainless steel pearl 12, press lock cutter gland 11, lock cutter spring 10 is compressed, lock cutlery-type stainless steel pearl 12 glides, selecting suitable toolbox 28 to insert holds in the knife assembly 26, unclamp lock cutter gland 11, the cutter spring 10 that contracts is replied, and cutter can use.Feed liquor Control Component 27 comprises feed liquor control spring 18, feed liquor spigot joint 19 and feed liquor control handgrip 20, press feed liquor control handgrip 20, feed liquor control spring 18 compresses backward, feed liquor spigot joint 19 is open-minded, and the space in normal saline enters between cutter 21 outer walls and outer cutter 22 inwalls enters in the body cavity to be washed.After cleaning finished, sewage excreted through discharge opeing interface 3 from the interior pipe of interior cutter 21.End of operation unclamps feed liquor control handgrip 20, and feed liquor control spring 18 is replied, and feed liquor spigot joint 19 is closed.
