Abstract
The utility model discloses a particles distributor, which comprises a magazine, a location mechanism, a propellant mechanism and a centre, and is characterized in that the magazine is arranged in the cassette in a sliding coordination and the cassette is arranged in the shell; the magazine is provided with a plurality of particle storage holes that store the particles and are arranged at the equal distance; and the centre arranged on the shell can be penetrated into the needle guide hole on the shell and the cassette and the particle storage hole on the magazine. The utility model has a compact structure and is able to fill the particles into the magazine on the protection platform, thereby effectively preventing the left-over particles. Additionally, the utility model realizes the continuous distribution of the particles, improves the efficiency and prevents the pollution.
Description
Technical field
This utility model relates to a kind of medical appliance, is that the miniature particle of a kind of implantation slow release medicine and radioactivity lays device in the micro particle of diseased region.
Background technology
At present, medical circle has been used particle implant surgery therapy in a large number in clinical treatment.Radioactive particle or slow releasing pharmaceutical particle are implanted near in the pathological tissues or corresponding position in patient's body with the method for not operating on through puncture needle.To realize the close-range treatment and the reaction of pathological tissues.The dosage that had so not only guaranteed to treat the accurate of target position but also can significantly reduce medicine.Reduced the treatment error effectively, avoided the injury of medicine non-pathological tissues.Overcome the influence of paying effect that pharmaceutical quantities causes greatly.Simultaneously because the doctor can use modern all radiography means that patient's pathological tissues is checked.And can utilize computing technique to duplicate the pathological tissues three-dimensional image.Make the treatment plan that drug particle is implanted through accurate Calculation.Can guarantee to destroy pathological tissues with minimum doses, the most effective therapeutic effect, to greatest extent, protect normal structure to greatest extent, this kind Therapeutic Method is not operated on, and has only the pin hole wound, has both made things convenient for the doctor to perform the operation, and is beneficial to wound healing again.Alleviate working doctor intensity, reduced the painful of patient and spending, increased the treatment success rate.Therefore be subjected to extensive patients and doctor's extensive welcome.But because the particle of implanting between being used to organize is general more small, the doctor is the single very difficulty of picking up in operation, and loss very easily comes off.As use radioactive particle, there is not effective protection also easily the doctor to be produced radiation injury.
Summary of the invention
The purpose of this utility model is for providing radioactive particle or slow releasing pharmaceutical implant surgery a kind of micro particle to lay device, can assisting a medicine accurately to implant diseased region and can make the doctor avoid radiation damage again.
The purpose of this utility model is achieved in that a kind of micro particle lays device, comprises magazine, detent mechanism, propulsive mechanism and thimble, and its magazine is contained in the cartridge clip, and it cooperates for being slidingly matched, and cartridge clip is contained in the shell; Magazine is provided with the particle storage holes of some storage micro particles that are equally spaced; Thimble can be applied in the guide pinhole and the particle storage holes on the magazine on shell and the cartridge clip.Described propulsive mechanism is a spiral propeller, and an end of milled screw and propeller support body is for being threaded, and the small end of milled screw is arranged in the axial hole of magazine one end.Described detent mechanism is the pellet shot from a slingshot detent mechanism, and the housing of pellet shot from a slingshot detent mechanism and cartridge clip be for being threaded, and the steel ball of billiard mechanism engages with taper hole on the magazine.The rail plate composition surface that magazine and cartridge clip reciprocatingly slide is square or triangle or pentagon or hexagon.Described magazine side is provided with some location taper hole that the steel ball with the pellet shot from a slingshot detent mechanism matches, and the spacing of adjacent positioned taper hole is consistent with the storage holes spacing that stores particle.The cartridge clip that is connected with spiral propeller is loaded in the shell, and between the two for movingly, shell is provided with the holding screw of tightening cartridge clip.Described cartridge clip, magazine, shell are made with radiation proof material.
In the operation preliminary preparation, can install on protecting stand with the micro particle that plan is implanted lay the device cartridge clip through disinfectant.Magazine can be prepared a plurality of.After the storage holes of magazine was all packed micro particle into, again the cartridge clip propeller of packing into, when the particle implant surgery arrived the link of cloth particle, as long as the assistant lays device with particle and delivers in the hands, the doctor just can lay continuously.Particle in a cartridge clip lays and finishes, and can change the outfit immediately that another is full of the cartridge clip of particle, continues to lay, and can not influence the carrying out of operation.In a word,, realize that particle lays continuously before operation, saved operating time greatly, improved operation efficient, thoroughly stopped the particle loss that comes off, prevented drug contamination effectively because this utility model can be loaded on micro particle in magazine, the cartridge clip in advance.
Description of drawings
Fig. 1 is this utility model sketch map;
Fig. 2 is cartridge clip and propelling thereof, detent mechanism sketch map.
The specific embodiment
Further specify this utility model below in conjunction with drawings and Examples.
Micro particle lays device and is made up of shell 1, cartridge clip 2, magazine 3, thimble 5, spiral propeller 6, pellet shot from a slingshot detent mechanism 7.Referring to Fig. 1.Cartridge clip 2 is installed in the shell 1, its composition surface is a rectangle, but the cartridge clip opposite shell is slided.Shell is provided with the holding screw of tightening cartridge clip.Magazine 3 is housed in the cartridge clip, both can slide neatly, its composition surface that matches is square, magazine 3 is provided with plurality of particles storage holes 4, the spacing of adjacent two particle storage holes equates, the outer surface of magazine is provided with the location taper hole of pellet shot from a slingshot detent mechanism steel ball, and is equidistant between adjacent two localized taper holes, and its distance equates with the spacing of adjacent two particle storage holes.The pellet shot from a slingshot detent mechanism is made up of housing, spring and steel ball, referring to Fig. 2.Steel ball engages with taper hole on the magazine 2 during the location, and housing and cartridge clip are for being threaded, and roll-shell can be adjusted the strength of the spring pushing steel ball of pellet shot from a slingshot detent mechanism.The inner end of magazine 3 is provided with the axial hole, and the little axle of the step axle of milled screw end is arranged in this hole.Spiral propeller 6 is made up of the support body of milled screw and spiral propeller, and an end of milled screw and the support body of spiral propeller is for being threaded.The other end of support body and cartridge clip 2 are fixing.Rotate milled screw, cartridge clip can be advanced and retreat.Item pin 5 can lay radioactive particle to the precalculated position by guide pinhole on housing and the cartridge clip and the particle storage holes on the magazine.This utility model can be selected in conveniently in advance, radioactive particle is stored in the magazine under the condition of safety, can lay continuously in the operation, saves operating time.Improve efficient, stopped the radioactive particle loss that comes off, prevented pollution.
