Description

Novel combined spinal-epidural anesthesia puncture kit

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a novel combined spinal-epidural anesthesia puncture kit.

Background

In human vertebral canal anatomy, a loose gap is formed between the ligamentum flavum and the dura mater, which is called an epidural space, and epidural anesthesia is to directly inject a medicament into the gap at one time or to carry out multiple administration through a catheter remained in the gap, so that the effect of maintaining long-term anesthesia is achieved.

The dura mater spinalis and the arachnoid membrane are directly and closely connected, and the puncture needle punctures layer by layer from the skin and reaches the epidural space after breaking through the ligamentum flavum; the needle is inserted further into the subarachnoid space after penetrating the dura mater and the arachnoid. Subarachnoid anesthesia involves injecting an anesthetic into the space.

In practice, the subarachnoid space is wide, and puncture administration (blind puncture, puncture under ultrasonic guidance and the like) is easy. Because the clearance of the epidural space is narrow, particularly, the epidural space of an old patient is difficult to puncture and reach, particularly, the epidural space is easy to pass through the deep space by mistake and enters the subarachnoid space, and the placing of the tube is difficult; in a comparison, if a balloon filled with water is provided, a piece of wet tissue is placed on the surface of the balloon, a water cavity in the balloon is a subarachnoid cavity, and a gap between the surface of the balloon and the wet tissue is an epidural cavity; the paper towel is directly pricked by a needle, and the paper towel is easy to be pricked into the water ball; but only the needle point breaks through the paper towel and stays on the surface of the water polo without breaking the water polo.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

Referring to fig. 1 to 5, the present invention provides an embodiment: the utility model provides a novel anesthesia puncture external member is united to lumbar vertebrae, includes arachnoid cavity of resorption pjncture needle 1, guide pjncture needle 2 and epidural puncture needle 3, 1 one end of arachnoid cavity of resorption pjncture needle with guide pjncture needle 2 is connected, epidural puncture needle 3 warp guide pjncture needle 2 cover is established on arachnoid cavity of resorption pjncture needle 1. The epidural catheter is characterized in that the subarachnoid cavity puncture needle 1 punctures the skin to the subarachnoid cavity, the cerebrospinal fluid can smoothly flow out after the puncture is successful, then the subarachnoid cavity puncture needle 1 is withdrawn to the point where the cerebrospinal fluid does not flow out, at the moment, the needle point of the subarachnoid cavity puncture needle 1 is withdrawn to the epidural cavity, the epidural puncture needle 3 is placed into the epidural cavity under the action of the guide puncture needle 2, then the subarachnoid cavity puncture needle 1 and the guide puncture needle 2 are withdrawn from the epidural puncture needle 3, and then the epidural catheter is placed into the epidural cavity through the epidural puncture needle 3, so that epidural administration or catheter placement can be performed.

With continued reference to fig. 1 and 4, the present invention provides a first embodiment of a subarachnoid puncture needle 1: still include first syringe adapter 4, first syringe adapter 4 includes adapter head 41 and U-shaped afterbody 42, adapter head 41 with U-shaped afterbody 42 is linked together, the terminal surface of subarachnoid cavity pjncture needle 1 is provided with first external screw thread 11, be provided with on the interior side wall of adapter head 41 with first external screw thread 11 meshes first internal thread 43 mutually.
