The specific embodiment
In order better to understand the technical scheme of this utility model, describe the embodiment that this utility model provides in detail below in conjunction with accompanying drawing.
This utility model embodiment provides a kind of location guide pin of fixing limbs foreign body; As shown in Figure 1, the location guide pin of this fixing limbs foreign body comprises: hollow needle 101, and the both sides of the front end of the needle point of said hollow needle 101 are provided with opening 102; The front end of said needle point also is equipped with a dilator 103; Be connected with steel wire 104 on the said dilator 103, said steel wire 104 passes said hollow needle 101, and exposes from the rear end of this hollow needle 101.This dilator 103 is used under the tension of steel wire 104 front end of said needle point is strutted from this opening 102, and preferably, said dilator 103 is spherosome or cone.
In addition, in other embodiment, as shown in Figures 2 and 3; The location guide pin of this fixing limbs foreign body also comprises the metallic pin 105 and trocar sheath 106 that matches; Wherein, said hollow needle 101 is sleeved in the said trocar sheath 106, and said metallic pin 105 also is sleeved in the said trocar sheath 106.Wherein, said metallic pin 105 is very tiny draw points
Through extremity foreign body position, B ultrasonic noinvasive guiding location, insert with foreign body position, location with metallic pin 105 earlier before the orthopaedic surgical operations operation, insert trocar sheath 106 along guide pin 105 then; At this moment guide pin 105 is outside in the sleeve pipe 106; Extract guide pin 105 then,, extract trocar sheath 106 then at the location guide pin that inserts the fixing limbs foreign body along trocar sheath 106 the insides; Under the guide pin stationary state of the location of fixing limbs foreign body; Upwards draw steel wire, the needle point of the location guide pin of fixing limbs foreign body expands to both sides to be opened, and forms fixing with foreign body in vivo.Accurately take out foreign body in the location with convenient operation.
More than the location guide pin of a kind of fixing limbs foreign body that this utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to this utility model embodiment; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to this utility model.
