Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to an implantation device for internal radiotherapy.

Background

Tumor radiotherapy is a local treatment for tumors using radiation. The radiation includes alpha, beta and gamma rays generated by radioactive isotopes, and x-rays, electron beams, proton beams and other particle beams generated by various x-ray therapeutic machines or accelerators. About 70% of cancer patients require radiation therapy in the course of cancer treatment, and about 40% of cancers can be cured by radiation therapy. The role and position of radiotherapy in tumor treatment are increasingly prominent, and the radiotherapy has become one of the main means for treating malignant tumors.

Radiotherapy includes both internal and external radiotherapy, which is brachytherapy in which a radioactive source is placed directly into the tissue to be irradiated or into the natural cavity of the body.

When the implantation operation for treating the malignant tumor in the bile duct and the pancreas is performed, the guide wire 1 is mostly used, and the bile duct and the pancreas are longer, the position of the malignant tumor is deeper, and the radiation source is difficult to accurately and directly place at a patient position by the existing implantation means.

Disclosure of Invention

Based on the above mentioned problems in the background art, the present invention provides an implantation device for internal radiotherapy, which is used to solve the problem that the existing implantation means is difficult to accurately and directly place the radioactive source on the patient.

The technical scheme adopted by the invention is as follows:

the utility model provides an implant device of usefulness of putting internally, includes pusher and implanter, the pusher includes pushing head, sleeve pipe and top, pushing head and top are all installed in sheathed tube both ends, the guiding hole has all been seted up to pushing head, sleeve pipe, top and implanter, set up on the implanter and place the chamber, the implanter has seted up a plurality of through-holes in placing the chamber and having corresponded the position, the closing cap is installed in the open end of placing the chamber to the implanter.

On the basis of the scheme, the invention also improves the following steps:

further, the implanter comprises an implant body and a cover body, the placing cavity is formed in the implant body, a T-shaped fixture block is arranged on the cover body, a first T-shaped slot matched with the T-shaped fixture block is formed in the implant body, a traction wire is fixedly mounted on the T-shaped fixture block, a containing slot corresponding to the cover body is formed in the inner wall of the top head, and a second T-shaped slot is formed in the containing slot. The split type design of the implanter can also draw the cover body into the accommodating groove through the traction wire after the implanter is placed into the guide wire, so that the implant body is separated from the guide wire, and the guide wire does not need to be drawn out for continuous use.

Furthermore, one end of the first T-shaped slot is provided with a limiting block. The cover body is limited by the limiting block, and the cover body is prevented from being extruded and moved by the ejector in the implantation process.

Furthermore, an inclined plane is arranged at one end, far away from the top, of the implant body. The design through the inclined plane is favorable to reducing the propelling movement resistance when implanting, avoids better implanting the ware into.

Furthermore, one end of the top head, which is close to the implanter, is provided with a conical surface. The conical surface can make smooth transition between the implanter and the top head, and avoid the damage to human body caused by the protrusion of one end of the top head when implanting.

Furthermore, a first threading hole is formed in the plug, and the traction wire penetrates through the first threading hole. The traction wire is guided through the first threading hole, and the traction wire and the guide wire are prevented from interfering with each other to influence use.

Further, the pushing head is provided with a connector at one end, the sleeve is sleeved on the connector, the pushing head is provided with an L-shaped groove and a second threading hole, an L-shaped clamping block is clamped in the L-shaped groove, the traction wire penetrates through the second threading hole, and one end of the traction wire penetrating through the second threading hole is fixedly mounted on the L-shaped clamping block. The traction wire is pulled through the L-shaped clamping block, so that the cover body can be prevented from sliding and separating due to the fact that the traction wire is triggered during pushing.

Furthermore, a wire groove is formed in the L-shaped clamping block, the free end of the traction wire is located in the wire groove, and a limiting clamp is mounted at one end of the L-shaped clamping block of the traction wire. One end of the traction wire is located in the wire slot, the position of the limiting clamp is selected according to requirements, and the traction wire can be better fixed.

Furthermore, the pushing head is provided with a liquid injection hole, water can be injected into the sleeve through the liquid injection hole, and the guide wire is convenient to draw out.

The invention has the beneficial effects that:

put into the seal wire before the art, put into the radiation iodine particle and place the intracavity and fixed closing cap, locate the seal wire with pusher and implanter cover on, then promote the implanter through the pusher and remove to focus department, it takes out the seal wire to keep the fixed pulling seal wire of pusher to keep when arriving the focus to wait to implant the ware, implant the ware and keep static breaking away from the seal wire under the blockking of pusher, take out the pusher and make the implanter stop in focus department, high durability and convenient use, can be better implant the focus with the implanter.
