AI Technical Summary
Existing nerve block techniques are difficult to effectively analgesia of multiple nerves or plexus because anesthetics are difficult to take into account all nerve branches.
A plexus analgesic catheter was designed to extend the anesthetic to each nerve by adding cotton catheters to the front end of the catheter, using the permeability of cotton, thereby achieving analgesia of multiple nerves or plexus.
Through this catheter, anesthetics can effectively penetrate each nerve, achieving effective analgesia for multiple nerves or plexus, solving the problem of poor analgesia effects in the prior art.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field, in particular to a nerve plexus analgesia catheter. Background Art
[0002] With the popularization of the ERAS concept, another major task of clinical anesthesia is how to accelerate the patient's postoperative recovery and avoid complications. Among them, low opioid and nerve block combined with general anesthesia is an effective means of industry consensus. However, nerve block analgesia has some technical difficulties.
[0003] Nerve trunk block can be achieved by indwelling a catheter. Normally, a plastic catheter is placed near the nerve trunk, and anesthetics are pumped through the catheter to achieve continuous analgesia. However, this process is generally effective for a single nerve, but for multiple nerves or plexus blockade, the anesthetic may not be able to take into account all nerve branches, resulting in poor results. For this reason, we designed a plexus analgesia catheter. Utility Model Content
[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.
[0005] The utility model aims to provide a plexus analgesia catheter, which is convenient for extending and penetrating anesthetics into each nerve touched by a guide wire, thereby achieving analgesia for multiple nerves or plexuses.
[0006] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:
[0007] A plexus analgesia catheter comprises a tube body, one end of which is fixedly connected with a cotton guide wire.
[0008] As a preferred solution of the plexus analgesia catheter described in the utility model, the outer wall of the catheter body is provided with scale lines to facilitate marking the position of the liquid in the catheter.
[0009] As a preferred embodiment of the plexus analgesia catheter described in the utility model, one end of the cotton guide wire extends into the interior of the tube body, so that the drug solution in the tube body can diffuse into the cotton guide wire and gradually soak the cotton guide wire.
[0010] As a preferred embodiment of the plexus analgesia catheter described in the utility model, the cotton guide wire is coated with biological glue on the outside, and the biological glue is combined with an extrusion process to make the cotton guide wire in a hard state, which is conducive to catheterization.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The utility model cooperates with the tube body and the cotton guide cord, and adds a section of cotton guide cord to the front end of the analgesic catheter. Through the penetration of cotton, the anesthetic is extended to penetrate into each nerve touched by the guide cord, thereby achieving analgesia for multiple nerves or nerve plexuses. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] In order to more clearly illustrate the technical solution of the implementation of the utility model, the utility model will be described in detail below in combination with the drawings and detailed implementation. Obviously, the drawings described below are only some implementations of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative labor. Among them:

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0019] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.
[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0021] See also Figure 1-3 The utility model provides a plexus analgesia catheter, comprising a tube body 1, wherein the outer wall of the tube body 1 is provided with scale lines 3 for marking the position of the liquid in the catheter.
[0022] One end of the tube body 1 is fixedly connected to a cotton guide wire 2, wherein one end of the cotton guide wire 2 extends into the interior of the tube body 1, so that the liquid medicine in the tube body 1 can diffuse into the cotton guide wire 2 and gradually soak the cotton guide wire 2. The outside of the cotton guide wire 2 is coated with biological glue, and the cotton guide wire 2 is made hard by an extrusion process combined with the biological glue, which is convenient for catheterization.
[0023] When in use, the length of the cotton guide wire 2 is retained as required, and the excess part is cut off. In this device, the outside of the cotton guide wire 2 is coated with biological glue, and the cotton guide wire 2 is in a hard state through biological glue and extrusion processing, so that it is convenient to have the same hardness as the tube body 1, which is conducive to catheterization (retaining the cotton guide wire 2 near the target nerve. One end of the cotton guide wire 2 is located in the tube body 1, and the drug solution diffuses to the cotton guide wire 2 through the tube body 1 and gradually soaks the cotton guide wire 2. The drug solution only needs to reach the position of the cotton guide wire 2, and does not require a very high flow rate. It only needs to use the cotton to guide the drug solution forward.
[0024] During the specific operation, first use ultrasound or other imaging equipment to puncture above the target plexus and ensure that the puncture path passes through all the nerves that need to be blocked (such as Figure 3 ), when the puncture needle reaches the target, the analgesic catheter body 1 with a cotton guide wire 2 at the front end is inserted. When the cotton guide wire 2 reaches the front end of the puncture needle, the puncture needle is withdrawn, and the cotton guide wire 2 remains near the target nerve. Then the catheter body 1 is fixed and connected to an analgesic pump or other analgesic device.
[0025] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
