Description

Tumor intervention therapeutic device

Technical field

The utility model relates to the field of medical instrument technology, specifically tumor intervention therapeutic device.

Background technique

Tumor disease is once made a definite diagnosis, and generally in mid-term or advanced stage, the body of patient is tormented very weak at this time, such as The chemotherapy or radiotherapy that fruit carries out the surgical operation of tumor resection again and comes one after the other, side effect is very big, is easy to injure patient Body it is basic, it is extremely disadvantageous to the recovery of patient, so centering late tumor patient using most wide therapeutic modality is at present Interventional therapy, it is not necessarily to operate on, damages small, Small side effects, restores fast advantage, deep to be liked by doctor and patient.

But be exactly common universal injection puncture needle due to the tumour interventional therapy needle of the prior art, it is main to wrap Needle handle and needle body two large divisions are included, on the one hand, since the integral form of needle handle is more short and small, carrying out carcinoma intervention for patient Inconvenience grip when treatment, it is careless slightly, it is easy to cause cross-infection, the difficulty of work is increased to medical staff, is also existed The labor intensity of medical staff is added somewhat to, on the other hand, when interventional treatment operation, doctor is usually the thumb of the right hand Finger, index finger and middle finger pinch needle handle operation, and the differences such as disease sites and muscle strength of different patients intervene required when puncturing Power it is different, exert a force it is excessive is easy to wear out illing tissue or other internal organs, exert a force it is too small will increase that intervention punctures when Between, increase the pain of patient, in another aspect, the length due to needle body is longer, intervention is difficult to realize fine fine tuning, institute when puncturing To need a kind of novel tumor intervention therapeutic device.

Utility model content

The purpose of this utility model is to provide tumor intervention therapeutic devices, on the one hand it can utilize the palm of medical staff Force, facilitates being affectedly bashful and operating for interventional therapy needle, is on the other hand able to achieve the fine tuning to interventional therapy needle paracentesis depth, makes Medical needle more accurately acts on disease sites, increases the precision of interventional therapy.

The utility model to achieve the above object, is achieved through the following technical solutions:

Tumor intervention therapeutic device, including needle handle and needle body, the needle handle include shank body and handle cap, the lower end of the shank body Equipped with the circular hole cooperated with needle body, the upper end of the shank body is equipped with bearing mounting blocks, is equipped with axis on the bearing mounting blocks It holding, the rotation on bearings is connected with lead screw, and movable block is equipped on the lead screw, and the movable block is slidably connected with shank body, The movable block is fixedly connected with needle body, and first gear is fixedly connected on the lead screw, and the handle cap includes force section and consolidates Determine portion, the force section is fixedly connected with fixed part and shank body respectively, and short axle, the short axle are rotatably connected on the fixed part On be fixed with second gear, the second gear is engaged with first gear.

The outside of the force section is in spheroid shape, and the outer surface of the force section is equipped with anti-skid chequer.

The shank body is equipped with strip hole, and the side of the strip hole is equipped with size graticule.

The prior art is compared, the utility model has the beneficial effects that:

After finding the position that suitable intervention punctures, the force section of palm and interventional therapy device connects medical staff Touching is exerted a force using the palm of medical staff, facilitates being affectedly bashful and operating for interventional therapy needle, when the head of shank body passes through skin After surface layer and corium, with the help of the equipment such as B ultrasound or CT, the thumb wheel second gear of medical staff passes through gear Transmission drives lead screw rotation, so that movable block be driven to move down, it is able to achieve the fine tuning to interventional therapy needle paracentesis depth, So that medical needle is more accurately acted on disease sites, increases the precision of interventional therapy.
