Embodiment 1

[0023] Embodiment 1. An intraspinal analgesic catheter placement system for the treatment of refractory cancer pain

[0024] The present invention provides an intraspinal analgesic catheter insertion system for treating refractory cancer pain, the insertion system includes a puncture needle 1 covered with a cannula 2 on the outside for skin or blood vessel puncture; The guide wire 3 built in the cannula is used to guide other entering devices; the vascular sheath 5 of the guide wire 3 can be built in; the expansion of the guide wire 3 can be built in the vascular sheath 5 The tube 4 is used to expand the passage to facilitate the insertion of the PICC tube 6; the PICC tube 6 that can be built into the vascular sheath 5 is placed in the blood vessel or spinal canal for sampling or medication; the puncture needle 1 includes The needle seat and the needle tube fixedly connected, the needle seat is hollow and communicated with the needle tube, the needle tube part is made of metal...

Embodiment 2

[0025] Embodiment 2. A method of using a neuraxial analgesia catheter placement system for treating refractory cancer pain

[0026] (1) Select the puncture point, routinely disinfect the drape, and perform local infiltration anesthesia on the puncture point;

[0027] (2) Make an incision of 3 mm with a sharp blade, and bluntly separate the subcutaneous tissue. Under the guidance of C-arm fluoroscopy, the puncture needle 1 covered with a cannula 2 is successfully punctured into the subarachnoid space, and the puncture needle 1 is pulled out. See unobstructed cerebrospinal fluid return;

[0028] (3) Insert the guide wire 3 through the cannula 2, withdraw from the cannula 2, insert the vascular sheath 5 and the dilation tube 4 through the guide wire 3, withdraw the guide wire 3 and the dilation tube 4, and inject iodine through the vascular sheath 5 1ml of albuterol confirmed that the head of the vascular sheath 5 was located in the subarachnoid space;

[0029] (4) Then insert ...

Embodiment 3

[0031] Embodiment 3. An application case of an intraspinal analgesic catheter placement system for treating refractory cancer pain

[0032] The inventor used the implanted system of the present invention to continuously pump morphine into a patient with advanced cancer pain, and the treatment effect was good. The specific operation is as follows:

[0033]The patient was female, 57 years old, the main cause was "self-reported intractable pain in the lower abdomen, pelvis, and lumbosacral area for June, which aggravated in February, and was admitted. She was diagnosed with cervical cancer one year ago and was given systemic chemotherapy and radiotherapy in the Department of Internal Medicine. Obstinate pain in the abdomen, pelvis, and lumbosacral area. The nature of the pain is continuous pain. The VAS score is 8-10 points. Ketone sustained-release tablets 320mg, the analgesic effect is not good, mild nausea, accompanied by severe constipation after taking the medicine. Examinat...

Abstract

The invention belongs to the technical field of medical treatment, and particularly relates to an intraspinal analgesia catheter implantation system for treating the intractable cancer pain. The implantation system comprises: a puncture needle sleeved with a sleeve; a guide wire which can arranged in the sleeve; a blood vessel sheath in which the guide wire can be arranged; an expansion tube which can be arranged in the blood vessel sheath and in which the guide wire is arranged; and a PICC tube which can be arranged in the blood vessel sheath; The intraspinal analgesia catheter implantation system adopts high-grade medical silica gel, has excellent biocompatibility, is suitable for medium and long term indwelling, adopts a three-way valve design, prevents cerebrospinal fluid backflow, reduces the vessel blocking rate, and greatly reduces the economic burden of patients; according to the invention, the intrathecal analgesia has the advantages of exact analgesic effect, rapid response, small side effect, and small dosage of an analgesic drug, which is only 1/300 of the oral dosage. The method is convenient and rapid to operate, definite in curative effect and small in adverse reaction, greatly relieves the economic burden of patients, and is suitable to apply to advanced cancer pain patients.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to an intraspinal analgesia catheter insertion system for treating refractory cancer pain. Background technique [0002] Pain is a painful experience with sensory, emotional, cognitive, and social components associated with actual or potential tissue damage. Cancer is one of the primary diseases that threaten human survival, and cancer pain (hereinafter referred to as "cancer pain") is one of the most common cancer-related symptoms. Cancer pain refers to the pain caused by the tumor itself or related diseases, including cancer-related pain, cancer treatment-related pain, and pain caused by other causes. According to statistics, about 25% of newly diagnosed cancer patients, 55% of cancer patients receiving treatment and 66% of advanced cancer patients have symptoms of cancer pain. Cancer pain not only affects the quality of life of patients, but also persistent and sev...
