Abstract
The utility model discloses an autogenous fat cell injection cannula which comprises an injector and a needle head installed on the injector. A needle hole used for injecting fat is arranged in the needle head, the needle point of the needle hole is closed, and at least two injection side holes which are arranged close to the needle point are formed in the side wall of the needle hole. According to the autogenous fat cell injection cannula, the needle point of the needle hole is closed, the injection side holes are formed in the side wall of the needle hole, and the flow area of the injection side holes is larger than the cross sectional area of the needle hole, so that the flow area of the injected fat is effectively increased, cells are prevented from being blocked, and the fat cells are injected more conveniently and rapidly.
Description
Technical field
This utility model belongs to technical field of medical instruments, and concrete is a kind of autologous fat injection cell sleeve pipe that is used for injection fat in the fat transplantation Packing Technique.
Background technology
Come from the refuse reclamation of the adipose cell after liposuction, the transplanting Packing Technique of autologous fat also more and more is subjected to extensive patients and asks beautiful person to pursue.Due to the autologous tissue that is the patient, transplanting is filled safe and effective due to autologous fat, usually is used for filling Facial Depression (caving in as depression, temples after wound), enlarges the bosom, fills buttocks etc.
Need after the autologous fat cell extraction with injector to inject in filling the position, due to adipose cell or adipose cell group granule large, be easy to stop up syringe needle, cause injecting and to operate inconvenience; Perhaps when pressure was excessive, syringe needle can separate with syringe, caused adipose cell directly to spray from syringe, caused waste, even caused the injection cell amount insufficient and affect filling effect.
Present autologous fat cell generally adopts syringe needle (12x38TW LB model) to be injected in and fills the position, although this syringe needle can satisfy the requirement of fat injection to a certain extent, also has three deficiencies:
1, the too sharp-pointed easy damaged blood vessel of syringe needle and tissue;
2, the pin hole that is arranged on needle tip very easily stops up;
When 3, injection pressure was excessive, syringe needle separated with syringe and causes adipose cell waste.
In view of this, this utility model is intended to explore a kind of autologous fat injection cell sleeve pipe, and this autologous fat injection cell sleeve pipe not only can satisfy the injection demand of adipose cell, and can prevent that cell from stopping up, and makes the adipose cell injection more convenient.
Summary of the invention
The technical problems to be solved in the utility model is to propose a kind of autologous fat injection cell sleeve pipe, this autologous fat injection cell sleeve pipe not only can satisfy the injection demand of adipose cell, and can prevent that cell from stopping up, make the adipose cell injection more convenient.
Realize above-mentioned technical purpose, autologous fat injection cell sleeve pipe of the present utility model, comprise syringe and the syringe needle that is arranged on syringe, be provided with for injection fat in described syringe needle and at the pin hole of needle point place's sealing, the sidewall of described pin hole is provided with at least two injection side openings that arrange near described tip positions.
Further, adopt screw connection structure to be connected between described syringe and syringe needle.
Further, described injection side opening is set to 4-6.
Further, described syringe needle is at the blunt circle in needle point place.
The beneficial effects of the utility model are:
Autologous fat injection cell sleeve pipe of the present utility model, by with pin hole in the sealing of needle point place, and a plurality of injection side openings are set on the sidewall of pin hole, the circulation area of a plurality of injection side openings is greater than the cross-sectional area of pin hole, namely can effectively increase the circulation area of injection fat, can prevent that cell from stopping up, make the adipose cell injection more convenient.
Description of drawings
Fig. 1 is the structural representation of this utility model autologous fat injection cell sleeve pipe embodiment;
Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment
As shown in Figure 1, be the structural representation of this utility model autologous fat injection cell sleeve pipe embodiment.The autologous fat injection cell sleeve pipe of the present embodiment, comprise syringe 1 and the syringe needle 2 that is arranged on syringe 1, be provided with in syringe needle 2 for injection fat and at the pin hole 3 of needle point place's sealing, the sidewall of pin hole 3 is provided with at least two injection side openings 4 that arrange near tip position, syringe 1 can adopt existing multiple syringe to realize, is not repeated.
Preferably, injection side opening 4 is set to 4-6, can either satisfy the injection circulation requirement of adipose cell, and can the structure of pin hole 3 not affected greatly.The injection side opening 4 of the present embodiment is set to 4, and on the sidewall that a group is distributed on pin hole 3 in twos.
The autologous fat injection cell sleeve pipe of the present embodiment, by with pin hole 3 in the sealing of needle point place, and a plurality of injection side openings 4 are set on the sidewall of pin hole 3, the circulation area of a plurality of injection side openings 4 is greater than the cross-sectional area of pin hole 3, namely can effectively increase the circulation area of injection fat, can prevent that cell from stopping up, make the adipose cell injection more convenient.
Further, adopt screw connection structure to be connected between syringe 1 and syringe needle 2, screw connection structure comprises the external screw thread port that is arranged on syringe 1 union joint and is arranged on syringe needle 2 tail ends is screw thread port, by adopting screw connection structure to be connected between syringe 1 and syringe needle 2, can effectively strengthen the bonding strength of syringe 1 and syringe needle 2, even under the excessive condition of injection force, syringe needle 2 can not separate with syringe 1 yet, prevents that adipose cell from spraying waste.
Further, syringe needle 2 adopts the syringe needle 2 of this structure at the blunt circle in needle point place, can effectively prevent syringe needle 2 disorganizes and blood vessel, is convenient to the patient and recovers.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, this utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
