Abstract

The utility model relates to a radio frequency therapeutic instrument multiple warhead anchor shapepinhead which comprises a needle cylinder for puncturing the needle cylinder and a needle stylet handle which is arranged in the needle cylinder. The utility model is characterized in that: the inner side of the needle stylet handle is provided with a needle stylet which consists of at least three independent metal elastic silk gathering heads and a needle pole, the gathering heads of the needle stylet automatically extend with an umbrella shape and form an anchor head whose diameter is 1.50-10.00 centimeters when gliding out of the nozzle of the puncturing thimble. The utility model can augment the energy, the temperature and the curing range of the radio frequency which is emitted by the radio frequency therapeutic instrument, to richly distribute the function of the radio frequency. The clinic test validates that the utility model greatly elevates the applying range of the radio frequency and in particular has marked curing effect to the bigger knubs(3-6 centimeters).

Description

Radio-frequency therapeutic equipment multiple warhead anchor shape syringe needle

The utility model relates to the accessory of medical apparatus and instruments, especially a kind of radio-frequency therapeutic equipment multiple warhead anchor shape syringe needle.

The electrode syringe needle is to be the new ideas syringe needle that cooperates radio-frequency therapeutic equipment to design, and it is mainly used in the elimination of in-vivo tumour.Common electrode syringe needle is made up of puncture casing and the nook closing member and the nook closing member handle that set within it.The electrode syringe needle is connected with radio-frequency therapeutic equipment by lead, the radio-frequency (RF) energy and the temperature of nook closing member end in the radio-frequency therapeutic equipment may command electrode syringe needle.During clinical operation, the puncture casing of electrode syringe needle is thrust patient's tumor locus, will be arranged on nook closing member in the puncture casing then and release and thrust tumor.Then, set best temperature, time, power and impedance,, make nook closing member end cancerous tissue albumen generation coagulation necrosis on every side, reach the therapeutic purposes of killing cancerous tissue by the nook closing member end emission high energy rf wave of radio-frequency therapeutic equipment to the electrode syringe needle according to the state of an illness.Existing electrode syringe needle is the single needle cored structure, and its radio-frequency (RF) energy, temperature and therapeutic domain are very limited, clinical proof, and its therapeutic effect can not be given full play to.

The purpose of this utility model is the deficiency that exists at above-mentioned electrode syringe needle, and a kind of radio-frequency therapeutic equipment multiple warhead anchor shape syringe needle that can increase radio-frequency (RF) energy, temperature and therapeutic domain is provided.

Radio-frequency therapeutic equipment multiple warhead anchor shape syringe needle of the present utility model, comprise: be provided with the syringe of puncture needle tubing and the nook closing member handle that sets within it, it is characterized in that: the nook closing member that is made of 3 independent metallic elastic silk head clusters and shank at least is set in the nook closing member handle, the head cluster of described nook closing member can be umbrella automatically when skidding off the puncture casing mouth of pipe launches, and can form the anchor head that diameter is 1.50～10.00CM.

Radio-frequency therapeutic equipment multiple warhead anchor shape syringe needle design principle of the present utility model is: the characteristic of utilizing the metallic elastic silk can launch automatically when breaking away from constraint, the head cluster that the metallic elastic silk constitutes only can be umbrella and launches skidding off puncture casing mouth of pipe rear, therefore its unfolded size is controlled by the operator fully, the length that head cluster skids off the puncture needle tubing mouth of pipe is few, and unfolded anchor head diameter range is just little; The length that head cluster skids off the puncture needle tubing mouth of pipe is many, and unfolded anchor head diameter range is just big.And after launching each independently metallic elastic silk end all will become can be with the electrode tip of the high energy rf wave output of radio-frequency therapeutic equipment emission.

Radio-frequency therapeutic equipment multiple warhead anchor shape syringe needle design science of the present utility model, structure is ingenious, reasonable, and it can increase the scope of energy, temperature and the treatment of radio-frequency therapeutic equipment emission radio frequency, gives full play to the function of radio-frequency therapeutic equipment.Clinical trial certificate, this multiple warhead anchor shape syringe needle improves the scope of application of radio-frequency therapeutic equipment greatly, and especially (3～6CM) have notable therapeutic effect to bigger tumor.

The concrete structure of this utility model radio-frequency therapeutic equipment multiple warhead anchor shape syringe needle by the following drawings and

Embodiment provides in detail.

Fig. 1 is a radio-frequency therapeutic equipment multiple warhead anchor shape needle head structure sketch map;

Fig. 2 is a radio-frequency therapeutic equipment multiple warhead anchor shape syringe needle deployed condition sketch map shown in Figure 1.

Embodiment: can be clear that from Fig. 1, the basic structure of radio-frequency therapeutic equipment multiple warhead anchor shape syringe needle is identical with common single needle core electrode syringe needle, comprise syringe 3, nook closing member handle 2 that is provided with puncture needle tubing 1 and the blanking cover 4 that is arranged on nook closing member handle 2 tail ends, nook closing member handle 2 is plugged in the syringe 3, nook closing member handle 2 inner chambers 5 are provided with umbrella nook closing member 6, and by blanking cover 4 sealings that are arranged on nook closing member handle 2 tail ends; Described umbrella nook closing member 6 is made of shank 7 and the head cluster 8 that is arranged on its end, and head cluster 8 is made of 5 independent metallic elastic silks; Be in axial sliding along puncture needle tubing 1 inner chamber during umbrella nook closing member 6 power effect outside nook closing member handle 2, the head cluster 8 of umbrella nook closing member 6 ends is when skidding off puncture casing 1 mouth of pipe 9, the metallic elastic silk of head cluster 8 can be umbrella automatically to launch, and can form diameter is the anchor head (see figure 2) of 1.50～10.00CM.The afterbody of umbrella nook closing member 6 is provided with the link 10 that is connected with radio-frequency therapeutic equipment.

Claims

1, a kind of radio-frequency therapeutic equipment multiple warhead anchor shape syringe needle, comprise: be provided with the syringe of puncture needle tubing and the nook closing member handle that sets within it, it is characterized in that: the nook closing member that is made of 3 independent metallic elastic silk head clusters and shank at least is set in the nook closing member handle, the head cluster of described nook closing member can be umbrella automatically when skidding off the puncture casing mouth of pipe launches, and can form the anchor head that diameter is 1.50～10.00CM.
