The invention discloses an intraspinal anesthesia puncture guide system with an optical visualization function. The intraspinal anesthesia puncture guide system comprises an epidural needle body module, an optical tracking and positioning module and an image processing and displaying module. The epidural needle body module comprises a needle body and an optical probe, and the optical probe is fixed to the needle body and used for collecting images of the environment in front of the needle body. The optical tracking and positioning module comprises a positioning marker and an optical positioning camera, the positioning marker is fixed to the needle body, and the optical positioning camera is used for determining space pose information of the positioning marker. And the image processing and displaying module is connected with the optical probe and the optical positioning camera, and is used for generating an intra-spinal anesthesia puncture auxiliary image according to the image of the environment in front of the needle body and the spatial pose information of the positioning marker, and displaying the intra-spinal anesthesia puncture auxiliary image. According to the application, convenience is provided for epidural puncture through an optical visualization function, so that the success rate of epidural puncture is improved, and the operation difficulty and risk are reduced.

The invention discloses an epidural nerve releasing kit, and relates to the technical field of medical instruments. Comprising an epidural needle used for puncturing into the epidural space, a nerve releasing catheter entering the epidural space through the epidural needle, a locking connector matched with the nerve releasing catheter for medicine injection and an electrical stimulation assembly for conveying stimulation current to a pain part through the nerve releasing catheter. Through mutual cooperation of the epidural needle, the nerve releasing catheter, the locking connector and the electrical stimulation assembly, a doctor is assisted in completing a nerve releasing operation, and the operation efficiency is improved.

The invention discloses an intraspinal anesthetic needle puncture virtuality and reality combined teaching system, which relates to the technical field of medical teaching evaluation, and comprises the following steps of: 1, compiling an index definition library, a Chinese word matrix and a report template into a rule net version through unit and dimensional reasoning and equation and interval checking, and carrying out property test; 2, aligning and normalizing the multi-source sequence and the event according to a conversion chain, and packaging into a fact package containing a source, a formula and a unit; 3, generating a rendering plan based on the fact package, preposing word use and display precision, and pre-scoring; 4, constrained generation and reverse checking are carried out, minimum correction is carried out under the condition that a fact numerical value is not changed, and a consistency text and a final consistency score are output; 5, signing and issuing a gating and embedding a pedigree and a signature; in case of data, threshold or template change, calculating a change influence domain, re-rendering the influenced sentences, and outputting differences and auditing; consistency, traceability and verifiability of facts and characters are realized.

The invention discloses a telescopic anesthesia catheter, and relates to the technical field of medical instruments, the telescopic anesthesia catheter comprises a catheter body, and the catheter body is provided with a catheter wall made of a flexible material; a medicine cavity channel for injecting medicine is formed in the tube wall; a head end for inserting an epidural needle tube is formed on one side of the medicine cavity channel, and a tail end for injecting medicine is formed on the other side of the medicine cavity channel; the metal wire is connected into the medicine cavity channel and extends from the head end to the tail end in the length direction of the medicine cavity channel; the elastic expansion component is connected between the inner wall of the tube wall and the metal wire and is configured to be capable of contracting towards the inner side and expanding towards the outer side in the radial direction of the medicine cavity channel, so that the tube wall can move between a folded contraction state in which the tube wall is driven by the elastic expansion component to the inner side and an expanded expansion state in which the tube wall is driven by the elastic expansion component to the outer side; the aperture of the tube wall can be adjusted relative to the wound to block the gap between the wound and the tube wall.

An epidural needle with a mechanism to receive real-time feedback on the location of the epidural needle during insertion process of the epidural needle. In particular, the epidural needle includes a spring and a pair of needles coupled to a force-measuring sensor for a continuous measurement of the force at a tip of the epidural needle as the epidural needle is inserted. The spring is enclosed in a spring section between a lug section and a needle section. The lug section comprises the force-measuring sensor and the needle section comprises a needle to be inserted. The lug section, the spring section and the needle section are axially aligned along an epidural needle axis. A force is transmitted from the needle section through the spring of the spring section to the force-measuring sensor of the lug section.
