Abstract
A pelvis needle inserting guiding device is characterized in that two arc rods and a sleeve transversely fixed at one ends of the vertical arc rods are included, the other ends of the two arc rods are hinged together, and a spring is connected between the two arc rods. Compared with the prior art, the pelvis needle inserting guiding device has the advantages that a needle can not be deviated easily when being inserted, and safety is achieved.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments.
Background technology:
Pelvis is threaded a needle without special guiding apparatus at present, and operation technique is with patient's experience, and conventional front side entry point is selected from the above 2～4cm place of anterior superior iliac spine, goes out the inboard that pin mark is selected from offside posterior superior iliac spine or slightly biased posterior superior iliac spine, squeezes into iron hammer from front to back.Because the ilium wall is smooth, be offset easily during inserting needle, thereby damage enteric cavity, blood vessel, nerve etc., cause threading a needle unsuccessfully.
Summary of the invention:
Goal of the invention of the present utility model is not easy when being to provide a kind of inserting needle to be offset, the pelvis puncture guider tool of safety.
This utility model be achieved in that comprise two bows, wherein the other end of sleeve, two bows of an end is hinged laterally to be fixed on vertical bow, is connected with spring between two bows.
During use, along hinged two bows are pulled open, making wherein, the inner outlet of a sleeve faces toward the above 2～4cm place of anterior superior iliac spine, the interior side outlet of another sleeve is facing to the inboard of side posterior superior iliac spine or slightly biased posterior superior iliac spine, make two bows relatively close, the axis of two sleeves is on the same straight line, and then pelvis being threaded a needle imports in the sleeve, squeezes into iron hammer from front to back.Under the guide effect of sleeve, pelvis is just threaded a needle and can be pierced in another sleeve from a sleeve wherein, has guaranteed that pelvis threads a needle successfully.
Here, in order to guarantee to locate, the axis of two sleeves is on the same straight line, be provided with detent mechanism at two bows, detent mechanism comprises the connecting rod that is arranged on the bow, is arranged on the locating rod between two connecting rods of two bows, and locating rod is connected to connector between two connecting rods.During use, bow is positioned at the sufferer place after, two connecting rods are pulled open, then by connector locating rod is fixed between two connecting rods.Because after locating rod is fixed between two connecting rods, the position of bow is just fixing, and the axis that is fixed on the sleeve on two bows just is on the same straight line, people just can thread a needle pelvis exactly and pierce in another sleeve from a sleeve wherein, have guaranteed that pelvis threads a needle successfully.
Here, use for convenient, connector is hinged or bayonet socket, and locating rod one end is hinged on wherein on the connecting rod by hinged, is provided with bayonet socket at another connecting rod, and the other end of locating rod is connected on the bayonet socket of another connecting rod.
Compared with the prior art this utility model is not easy when having inserting needle to be offset, the advantage of safety.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is user mode figure of the present utility model.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments this utility model is done and is described in further detail:
As shown in the figure, this utility model comprises the bows 1 of two approximate 1/4 circles, wherein the other end 3 of sleeve 2, two bows 1 of an end is hinged laterally to be fixed on vertical bow 1, and 1 of two bow are connected with spring 4.
Be provided with detent mechanism at two bows 1, detent mechanism comprises the connecting rod 5 that is arranged on the bow 1, is arranged on the locating rod 6 of 5 on two connecting rods of two bows 1, locating rod 6 is connected to the connector of 1 on two connecting rods.
Connector is hinged 7 or bayonet socket 8, and locating rod 6 one ends are hinged on wherein on the connecting rod 1 by hinged 7, are provided with bayonet socket 8 at another connecting rod 1, and the other end of locating rod 6 is connected on the bayonet socket 8 of another connecting rod 1.
Here, bow 1 is fixed on the medium position of sleeve 2.Like this, bow 1 just is not easy to run into human body.Prevented that bow 1 from causing the axis of two sleeves 2 not to be located along the same line because running into human body.
