Abstract

The radiotherapeutic particle implanting gun is used for implanting radiotherapeutic particle into body of cancer patient. It includes a gun body, a handle, a particle gun capable of being inserted into the gun body, an implanting needle and a push rod. The gun body consists of a particle bin seat, a front cover plate, a back cover plate, an implanting needle pinch plate, and a push rod guiding tube. The implanting needle has a central hole and a conic tail hole, and is fitted to the push rod guiding tube. The particle bin includes a casing, a spring and a mandril inside the casing, and a particle storing holder screwed to the casing. The mandril under the action of the spring may be pushed to the bottom of the particle storing holder and the push rod may be pushed to implant the particle into the disease focus of the patient. The radiotherapeutic particle implanting gun may be used to implant over hundred particles.

Description

A kind of radiotherapeutic particle implanting gun

Technical field

The present invention relates to material is implanted to technical field of medical instruments on the human body, especially relate to radioactive particle is implanted to medical apparatus and instruments on the human body.

Background technology

China is implanted to the interior radiotherapy technology of human body therapy tumor generally in clinical practice with radioactive particle at present, but must lean on import mostly for implantation instrument, these apparatuses cost an arm and a leg, domestic for this reason existing people is developing this type of apparatus, as China's utility model patent disclosed " implanting the visual implanting gun of treatment tumor between the seed source tissue ", notification number CN2524773Y, it is a kind of succedaneum preferably, it is with the radioactive particle of packing in the source of bank savings rotating disk, the enclosing cover shielding cover board, rotate source of bank savings rotating disk, numbering on the shielding cover board is aimed at, with sending the source pin particle to be gone out hole, source implant into body from source of bank savings rotating disk along rifle body upper channel with the numbering on the source of bank savings rotating disk; The source of bank savings of this rotating disk form is packed into and is sent particle and all need repeatedly rotate source of bank savings rotating disk, uses trouble.

Summary of the invention

The objective of the invention is provides a kind of radiotherapeutic particle implanting gun in order to overcome the deficiency of above-mentioned prior art, makes when packing radioactive particle into, can disposable continuous placement more than ten, and when human body is implanted, also can release continuously, thereby make simple to operate much easier.

For achieving the above object, technical scheme of the present invention is such: a kind of radiotherapeutic particle implanting gun, the handle that comprises the rifle body, is fixedly connected with the rifle body, can insert particle storehouse in the rifle body and implant needle, push rod, front and rear cover plate, the implant needle buckle that is fixed in the front shroud front that said rifle body fixes by the particle storehouse seat at middle part, with particle storehouse seat and be fixed on the front shroud and the pusher catheter pusher catheter rear portion anterior and that be fixed on the back shroud of passing the implant needle buckle constitutes; Be perforation in the middle of the said implant needle, the hole of afterbody is tapered, matches with the pusher catheter front portion, can be socketed in outside the pusher catheter, and the implant needle buckle on implant needle afterbody and the rifle body is interlockingly connected; The storage particle folder that said particle storehouse comprises housing, the intravital spring of shell and push rod, is spirally connected with housing, wherein push rod can push up to bottom land at the storage tank of the effect lower edge of spring storage particle folder, on the nearly bottom land of storage particle folder, have through hole, push rod can pass the particle that this through hole will store in the particle folder along pusher catheter and stretch out outside the implant needle always, implants patient's focus.

During use, as long as will store the particle folder screws out from the housing of particle storehouse, particle alignment is packed in the storage tank of storage particle folder, filling ten can screw in the housing of particle storehouse storage particle folder fixing, then the particle storehouse is injected on the particle storehouse seat on the rifle body, particle is close under the effect of spring and push rod, implants patient's focus by one one of push rod, and that storage particle storehouse can be joined is a plurality of, replaceable storage particle storehouse in the formality.

Owing to adopted technique scheme, a kind of radiotherapeutic particle implanting gun of the present invention has simple in structure, characteristics easy to use, but one-time continuous is loaded onto particle, also can release continuously when human body is implanted, and it is convenient to change the particle storehouse, and a formality can be implanted up to a hundred radioactive particles to patient.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Accompanying drawing is a structural representation of the present invention.

Among the figure: 1, handle, 2, the push rod shelf, 3, push rod, 4, pusher catheter afterbody, 5, back shroud, 6, the rifle body, 7, storage particle folder, 8, push rod, 9, housing, 10, particle storehouse, 11, particle storehouse seat, 12, front shroud, 13, implant needle buckle, 14, implant needle, 15, the pusher catheter front portion, 16, through hole.

The specific embodiment

Shown in accompanying drawing, a kind of radiotherapeutic particle implanting gun of the present invention, the handle 1 that comprises rifle body 6, is fixedly connected with the rifle body, can insert particle storehouse 10 in the rifle body and implant needle 14, push rod 3, the front and

rear cover plate

12,5 that said rifle body 6 fixes by the particle storehouse seat 11 at middle part, with particle storehouse seat, be fixed in the implant needle buckle 13 on the front shroud 12 and be fixed on the front shroud 12 and pass the pusher catheter anterior 15 of implant needle buckle 13 and the pusher catheter rear portion 4 that is fixed on the back shroud 5 constitutes; In the middle of the said implant needle 14 is perforation, and the hole of afterbody is tapered, matches with pusher catheter front portion 15, can be socketed in outside the pusher catheter front portion, and the implant needle buckle on implant needle afterbody and the rifle body is interlockingly connected; The storage particle folder 7 that said particle storehouse 10 comprises housing 9, the intravital spring of shell and push rod 8, is spirally connected with housing, wherein push rod can push up to bottom land at the storage tank of the effect lower edge of spring storage particle folder, on the nearly bottom land of storage particle folder, have through hole 16, push rod 3 can pass the particle that this through hole will store in the particle folder along pusher catheter and stretch out outside the implant needle always, implants patient's focus;

For ease of the interim placement of push rod when carrying out implant procedure, on back shroud, also be fixed with push rod shelf 2.
