Description

Particle implantation microphone connector

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to particle is implanted and is used mike needle connector.

Background

The Mick TP needle is also called a radioactive particle implantation needle, consists of a needle tube and a needle seat, is matched with a radioactive particle implantation protective gun for use, implants radioactive iodine-125 particles into tumors in a human body puncture mode, utilizes low-energy rays continuously released by the iodine-125 particles to limitedly kill diseased tissues and protect normal tissues. The iodine-125 particles have long half-life period, can continuously and effectively kill cells, and meanwhile, the radiation particle implantation operation is short, can be completed under the condition of local anesthesia, is favorable for the acceptance and subsequent rehabilitation of patients, and is widely applied to the treatment process of middle and late stage tumor patients.

However, the needle seat of the currently used mike needle has small aperture, can not be directly connected with an injector, and can not be used for needle administration or deep anesthesia, thereby limiting the application scene of the mike needle.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of the prior art, and providing a particle implantation microphone connector which can directly connect a microphone and an injector and realize local deep anesthesia.

In order to achieve the purpose, the technical scheme is as follows:

a particle implantation microphone connector comprises a connecting end, a needle seat, a needle body and a needle point, wherein the connecting end is of a hollow funnel structure and is used for being connected with a syringe and used for needle administration or deep anesthesia; the tail part of the needle base is connected with the connecting end, and the head part of the needle base is provided with a circular recess matched with the mike needle sheath, so that the needle body of the connector and the mike needle sheath are ensured to be positioned in concentric circles; the tail part of the needle body is coated inside the needle seat, the outer diameter of the needle body is smaller than the inner diameter of the needle sheath of the mike needle, and the needle body can be inserted into the needle sheath of the mike needle; the needle point is arranged at the head of the needle body.

As another preferred scheme of the utility model, the connecting end and the needle seat are made of acrylonitrile-butadiene-styrene plastic and are connected through integral forming.

As another preferred scheme of the utility model, the diameter of the connecting end port is 2-4 mm to adapt to the syringes of different specifications.

As another preferred proposal of the utility model, the needle body is made of stainless steel, the length is 18-22 cm, and the diameter is 1-2 mm.

As another preferred scheme of the utility model, the needle point is the inclined plane, and length is 3mm, more is favorable to the discharge of injection medicine.

Compared with the prior art, the utility model provides a microphone connector for particle implantation has following gain effect:

the utility model provides a particle is implanted and is used mike needle connector carries out under the prerequisite that the particle was implanted and is used the scene not influencing mike needle, through linking to each other it with the syringe, has increased medicine injection function, carries out local anesthesia for the doctor and provides new method, the clinical operation of being convenient for more.
