Abstract
The utility model discloses a medical oncology interventional therapy needle. The medical oncology interventional therapy needle comprises a base. A cannula is arranged on the base. A puncture needle is sleeved with the cannula, a sealing thin film is arranged below the puncture needle, and an alcohol cotton layer is arranged on the bottom surface of the base. A negative pressure suction layer is arranged on the outer side of the puncture needle, and a main puncture pipe is arranged at the center of the puncture needle. A plurality of auxiliary puncture pipes are arranged between the main puncture pipe and the negative pressure suction layer. Each auxiliary puncture pipe penetrates through the negative pressure suction layer through an arc-shaped channel to be connected with the outside of the puncture needle. The heights of all the arc-shaped channels are different from the height of a port of the outer wall of the puncture needle, the top of the main puncture pipe and the tops of the auxiliary puncture pipes are respectively provided with a silicon gel sealing plug, and the interior of the main puncture pipe and the interiors of the auxiliary puncture pipes are respectively provided with a one-way valve. According to the medical oncology interventional therapy needle, the defects in the prior art can be overcome, the effect of one-time puncture multi-position therapy is achieved, the influence of hydrops around tumor tissue on therapy in the therapy process is reduced, and sanitation in the whole therapy process is guaranteed.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of Internal Medicine-Oncology interventional therapy needle.
Background technology
When tumour patient is carried out to expectant treatment, it is a kind for the treatment of means of commonly using that puncture gets involved.Existing interventional therapy needle only considers in design and to be easy to puncture and to prevent the aspects such as cross infection, ignored interventional therapy needle problem easy to use how after puncturing successfully.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of Internal Medicine-Oncology interventional therapy needle, can solve the deficiencies in the prior art, realize the effect of one-time puncture many places treatments, reduced the tumor tissues impact of hydrops on treatment around in therapeutic process simultaneously, guaranteed to treat omnidistance health.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
An Internal Medicine-Oncology interventional therapy needle, structure comprises base, is provided with sleeve pipe on base, is socketed with puncture needle in sleeve pipe, and the below of puncture needle is provided with sealing film, and the bottom surface of base is provided with alcohol swab layer; Puncture needle arranged outside has negative pressure absorbing layer, the center of puncture needle is provided with main puncture tube, between main puncture tube and negative pressure absorbing layer, be provided with several secondary puncture tubes, each secondary puncture tube is connected with the external world of puncture needle through negative pressure absorbing layer by a curved channel, all curved channels are all different from the height of the interface of puncture needle outer wall, the top of main puncture tube and secondary puncture tube is provided with silica gel sealing plug, and the inside of main puncture tube and secondary puncture tube is provided with unidirectional valve.
As preferably, described inside pipe casing is provided with rubber damping ring, rubber damping ring and puncture needle interference fit.
As preferably, between described base and sleeve pipe, be provided with universal drive shaft.
The beneficial effect that adopts technique scheme to bring is: the skin close contact of base of the present utility model and site of puncture, alcohol swab layer carries out disinfection to skin surface on the one hand, can also absorb the liquid oozing out from puncture wound in addition, keep exterior clean.Sleeve pipe is for fixing puncture needle, and what sleeve pipe can be according to interventional therapy by universal drive shaft need to adjust puncture angle.Under the effect of rubber damping ring, the piercing process of puncture needle is subject to damping force, can improve the accuracy of medical worker's puncture position, the injury of avoiding rocking of puncture needle to cause patient.Negative pressure absorbing layer use with to the hydrops of site of puncture with ooze out body fluid and clear up in time, reduce the impact on interventional therapeutic effect.Main puncture tube and secondary puncture tube have formed three-dimensional area for treatment, as required, use seal wire to carry out interventional therapy to diverse location, without the position that changes puncture needle, have reduced the injury to patient.Unidirectional valve can be avoided backflowing of the medicine for the treatment of position and patient's body fluid itself.Silica gel sealing plug has from close property, can keep the gnotobasis of puncture needle inside, and silica gel sealing plug has also played the effect of damping to the seal wire penetrating in addition, improves the accuracy of penetration depth and position.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a specific embodiment of this utility model.

In figure: 1, base; 2, sleeve pipe; 3, puncture needle; 4, alcohol swab layer; 5, negative pressure absorbing layer; 6, main puncture tube; 7, secondary puncture tube; 8, curved channel; 9, silica gel sealing plug; 10, unidirectional valve; 11, sealing film; 12, rubber damping ring; 13, universal drive shaft.
The specific embodiment
With reference to Fig. 1-2, structure of the present utility model comprises base 1, is provided with sleeve pipe 2 on base 1, is socketed with puncture needle 3 in sleeve pipe 2, and the below of puncture needle 3 is provided with sealing film 11, and the bottom surface of base 1 is provided with alcohol swab layer 4; Puncture needle 3 arranged outside have negative pressure absorbing layer 5, the center of puncture needle 3 is provided with main puncture tube 6, between main puncture tube 6 and negative pressure absorbing layer 5, be provided with several secondary puncture tubes 7, each secondary puncture tube 7 is connected with the external world of puncture needle 3 through negative pressure absorbing layer 5 by a curved channel 8, all curved channels 8 are all different from the height of the interface of puncture needle 3 outer walls, main puncture tube 6 is provided with silica gel sealing plug 9 with the top of secondary puncture tube 7, and main puncture tube 6 is provided with unidirectional valve 10 with the inside of secondary puncture tube 7.
It should be noted that described sleeve pipe 2 inside are provided with rubber damping ring 12, rubber damping ring 12 and puncture needle 3 interference fit.
In addition, between described base 1 and sleeve pipe 2, be provided with universal drive shaft 13.
Operation principle of the present utility model is: the skin close contact of base 1 of the present utility model and site of puncture, alcohol swab layer 4 carries out disinfection to skin surface on the one hand, can also absorb the liquid oozing out from puncture wound in addition, keeps exterior clean.Sleeve pipe 2 is for fixing puncture needle 3, and what sleeve pipe 2 can be according to interventional therapy by universal drive shaft 13 need to adjust puncture angle.Under the effect of rubber damping ring 12, the piercing process of puncture needle 3 is subject to damping force, can improve the accuracy of medical worker's puncture position, the injury of avoiding rocking of puncture needle 3 to cause patient.Negative pressure absorbing layer 5 use with to the hydrops of site of puncture with ooze out body fluid and clear up in time, reduce the impact on interventional therapeutic effect.Main puncture tube 6 and secondary puncture tube 7 have formed three-dimensional area for treatment, as required, use seal wire to carry out interventional therapy to diverse location, without the position that changes puncture needle 3, have reduced the injury to patient.Unidirectional valve 10 can be avoided backflowing of the medicine for the treatment of position and patient's body fluid itself.Silica gel sealing plug 9 has from close property, can keep the gnotobasis of puncture needle 3 inside, and silica gel sealing plug 9 has also played the effect of damping to the seal wire penetrating in addition, improves the accuracy of penetration depth and position.
