Detailed description of the invention
Further describe the present invention below in conjunction with specific embodiment and accompanying drawing.
A kind of needle set puncture fixed point orientation protector as described in Fig. 1-6; it comprises handle 1,6; and with these handle 1,6 corresponding connections and for pushing out the needle set guide plate 2,7 of puncture place vital tissue organ; on this needle set guide plate 2,7, correspondence is provided with the passage 3,8 for puncture needle is led, and the free end of this needle set guide plate 2,7 is obtuse.
This invention is fixed a point by needle set guide plate 2,7, then leads by 3,8 pairs of puncture needles of the passage on needle set guide plate 2,7, makes this utensil have the effect of fixing point of puncture position, puncture direction; Also can puncture place vital tissue organ be pushed out by this needle set guide plate 2,7, simultaneously, the free end of this needle set guide plate 2,7 is obtuse, can effectively avoid the puncture channel damage of vital tissue organ around, easy to use, safe, humanization designing and practical; In addition, adopt this utensil only to need a people to operate and do not need assistant to assist to push puncture place vital tissue organ on one side.
Operator and patient's relative position relation during because of work, angle β 1, β 2 between described handle 1,6 and described needle set guide plate 2,7 all need be to 90 °～135 °, the setting of this angle is associated in patient concrete use location with it with utensil, adopt corresponding β 1, β 2 angles in different use locations, with handled easily personnel's use, humanization designing; Meanwhile, by the setting of this angle β 1, β 2, hand-held utensil of handled easily person pushed puncture place vital tissue organ, and the operation of puncturing, laborsaving saving time, and do not need as broken with hands by operator or assistant in the past or other accessory is pushed.
Described passage 3,8 is groove or manhole, its concrete shape can that is to say that the concrete condition of needle set guide plate determines according to the concrete condition of utensil carrier, the guiding that this passage 3,8 is mainly used for puncture needle, avoid puncture needle vital tissue organ to patient in piercing process to cause damage simultaneously, therefore, this shape is except being groove or manhole, also can adopt other such as special-shaped through hole, diamond hole, more specifically, also can be U-shaped groove, semi-circular recesses, V-type groove etc.
Concrete; one embodiment of the present invention as shown in Figure 1, Figure 2; this needle set puncture fixed point orientation protector comprises handle 1; and that be connected with this handle 1 and for pushing out the needle set guide plate 2 of puncture place vital tissue organ; on this needle set guide plate 2, be provided with the passage 3 for puncture needle is led, and the free end of needle set guide plate 2 is obtuse.
Handle 1 in this embodiment is platy structure with needle set guide plate 2 and makes, and described passage 3 is along described needle set guide plate 2 length direction settings.Wherein, needle set guide plate 2 is formed by the direct blanking of platy structure, and handle 1 is batched and formed by platy structure, then handle 1 and needle set guide plate 2 are welded to connect, and polishes smooth.Certainly, structure being set and also can adopting other mode with the connected mode of needle set guide plate 2 of handle 1, such as handle 1 is stainless steel bar etc., connected mode is mechanical bolt or screw connection etc.It is one fan-shaped that described needle set guide plate 2 is specially, and its fan-shaped angle δ is 8 °～20 °, and its fan-shaped large end is connected with described handle 1, and fan-shaped small end is free end.The size that arranges for fan-shaped angle δ is associated in the concrete use location of human body with utensil, adopt corresponding δ angle in different use locations, when puncturing in human body lower jaw position, this fan-shaped angle δ should adopt low-angle, such as 8 °, 10 ° etc., with handled easily personnel's use.As shown in Figure 2, described fan-shaped large end and fan-shaped small end are circular-arc, are damaged by this needle set guide plate 2 with vital tissue organ around avoiding puncture channel.Described passage 3 is groove, and when use, puncture needle is close in this groove, and groove play the guiding role, so just avoided puncture channel around vital tissue organ damaged by this puncture needle.Be provided with many passages 3 in sector structure at described platy structure in as Fig. 2, be specially 3 grooves, and there is angle excursion between every passage 3, such as being 5 °, 8 ° equal angles between adjacency channel 3, for operator's operation of puncturing from different directions.
In this practical application, the shape that described needle set guide plate 2 also can adopt other is such as rectangle of surrounding rounding arc etc., and the quantity of passage 3 also can be determined by the layout of needle set guide plate 2 or specifically puncture direction or service condition.
Fig. 3, Fig. 4, Fig. 5, Fig. 6 illustrate another embodiment of the present invention, and it combines with the operating forceps in medical apparatus and instruments and be one-body molded.Particularly, described handle 6 comprises the first handle 61, the second handle 62 that are articulated in one, described needle set guide plate 7 comprises corresponding connection with this first handle 61, second handle 62 and integrated the first needle set guide plate 71, the second needle set guide plate 72, the cross section of this first needle set guide plate 71, the second needle set guide plate 72 is all style of the shoe and this style of the shoe plane is oppositely arranged, described passage 8 comprise be combined into manhole and the first semi-circular recesses 81, the second semi-circular recesses 82 on described the first needle set guide plate 71, the second needle set guide plate 72 respectively.
On current known medical operating pincers, transform, needle set guide plate 7 using the front end of medical operating pincers as this utensil, on this needle set guide plate 7, that is to say the first needle set guide plate 71, in the style of the shoe plane of the second needle set guide plate 72, correspondence is established the first semi-circular recesses 81, the second semi-circular recesses 82, this first semi-circular recesses 81, the second semi-circular recesses 82 combines a manhole, this manhole is as the passage 8 for puncture needle guiding, when use, by the needle set guide plate 7 on this operating forceps, the vital tissue organ of puncture place is pushed out and located, and close up operating forceps, again puncture needle is passed through by the first semi-circular recesses 81, the passage 8 that the second semi-circular recesses 82 combines is deeply to concrete position, to reach fixing point of puncture position, the effect of puncture direction.
The technical scheme above embodiment of the present invention being provided is described in detail, applied principle and the embodiment of specific case to the embodiment of the present invention herein and set forth, the explanation of above embodiment is only applicable to help to understand the principle of the embodiment of the present invention; , for one of ordinary skill in the art, according to the embodiment of the present invention, in detailed description of the invention and range of application, all will change, in sum, this description should not be construed as limitation of the present invention meanwhile.
