Example 1

The iodine particle implanter comprises a handle, a gun body and a storage, wherein one end of the gun body is fixedly connected with the handle, the other end of the gun body is provided with a mounting groove, the mounting groove is detachably connected with the storage, one side of the gun body is fixedly connected with an implantation gun head, an implantation passage is arranged in the implantation gun head, the implantation passage penetrates through the gun body, a push rod is arranged on one side, far away from the implantation gun head, of the gun body, one end of the push rod is inserted into the implantation passage, the implantation passage is communicated with the mounting groove, and the bottom of the storage is inserted into the implantation passage, so that iodine particles placed in the storage can enter the implantation passage. The side wall of the gun body is provided with a magnifying lens which is aligned with the joint of the implantation passage and the mounting groove.

Specifically, the magnifying lens is a convex lens or a fresnel lens.

In the process of implanting the iodine particles, the number of the iodine particles entering the implantation passage, namely the number of the iodine particles entering the patient body through the implantation passage in the current case, can be observed through the magnifying lens, so that the number of the iodine particles implanted into the patient body can be conveniently controlled, and the operation can be conveniently and smoothly performed.

Specifically, one end of the handle is fixedly connected with the gun body, and the other end of the handle is provided with a holding ring.

Furthermore, a transparent block is arranged in the gun body and covers the joint of the implantation passage and the mounting groove. The transparent block has the function that one side of the transparent block far away from the magnifying lens is simultaneously contacted with the implantation passage and the mounting groove, so that the condition of the joint of the implantation passage and the mounting groove can be observed through the transparent block.

As shown in fig. 1-3, an expanding structure is arranged at one end of the push rod away from the gun body. When in use, the expansion structure is pushed to drive the push rod to move towards the gun body, so that part of iodine particles in the storage are pushed along the implantation passage and finally enter the patient. The expanding structure can prevent the push rod from completely entering the implantation passage while reducing the pressure of the push rod on the hands of a doctor, so that the push rod is prevented from penetrating the implantation passage and stabbing tissues in a patient.

Further, the end of the implantation gun head, which is far away from the gun body, is gradually contracted so as to facilitate the implantation gun head to be placed into the patient.

During the operation, the iodine particles in the accumulator fall down and enter the implantation channel under the driving of gravity because the accumulator is in an inverted state. When the number of the iodine particles meets the operation requirement, the pushing rod is used for pushing the iodine particles in the implantation channel into the patient, and in the process, the side wall of the pushing rod is used for blocking the opening of the storage device, so that the residual iodine particles in the storage device are prevented from continuously entering the implantation channel.

Example 2

An iodine particle implanter as shown in fig. 4-5, which differs from embodiment 1 in that:

the side wall of the gun body is provided with a protecting cover which is covered on one side of the magnifying lens far away from the implantation passage. The protective cover is opened in the operation process to expose the magnifying lens, so that the joint of the implantation passage and the mounting groove can be clearly observed through the magnifying lens, and the number of iodine particles entering the implantation passage can be calculated. After the counting of the iodine particles is completed, a protective cover is used for shielding the amplifying lens so as to block the radiation of the iodine particles and reduce the harm of the iodine particles to medical staff.

After the operation is finished, the protective cover is used for blocking the magnifying lens, so that the magnifying lens is effectively prevented from being scratched accidentally, and the service life of the instrument is prolonged.

Specifically, one end of the protecting cover is hinged with the gun body, and the other end of the protecting cover is detachably connected with the gun body. When the protecting cover is opened, the protecting cover is not completely separated from the gun body, so that the amplifying lens can be shielded in time, and the protecting cover can be prevented from being lost.

One end of the restorer is abutted with the expanding structure, and the other end is abutted with the side wall of the gun body. The function of the restorer is that when the quantity of iodine particles in the current implantation channel is insufficient, the pressure on the push rod is gradually released, the restoring structure drives the push rod to move towards the direction away from the implantation gun head, the push rod is far away from the storage, and then the residual iodine particles in the storage can continuously enter the implantation channel. And (3) calculating the number of the iodine particles in the implantation channel again, and pushing the pushing rod again to push the iodine particles in the implantation channel into the patient body after the number of the iodine particles meets the operation requirement.

Further, one side of the gun body far away from the implantation gun head is fixedly connected with a guide tube, the implantation passage penetrates through the guide tube, and the push rod penetrates through the guide tube through the implantation passage. The guide tube serves to limit the movement direction of the push rod.

The foregoing is merely a specific embodiment of the application and other modifications and variations can be made by those skilled in the art in light of the above teachings.
