[0002] Ultrasound puncture and catheterization is a routine technique in critical care medicine, and is often used for rapid volume expansion and fluid replacement, critically ill patient rescue, central venous pressure monitoring, parenteral nutrition, chemotherapy drug infusion, and temporary pacemaker placement. The current PICC and CVC ultrasound puncture and catheterization, and difficult blood gas collection, usually use the transverse axis needle insertion method, and are often used with a puncture guide needle holder (sterile consumables). At present, there are the following problems: 1. The guide needle holder must be used in conjunction with a specific brand of color ultrasound machine, and is used with a probe with a connection base. Ordinary superficial probes cannot use the guide needle holder because they have no connection base at the transverse axis, which affects the efficiency of catheterization in critical care; 2. In the implementation of puncture and catheterization techniques that do not use a guide needle holder, such as difficult blood gas collection, it is often necessary to use a marker pen to mark the patient's skin after ultrasound positioning, and the ultrasound coupling agent and 75% alcohol for disinfection will remove the mark after marking, which seriously affects the accuracy of puncture and hinders aseptic operation.

[0023] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.
[0024] The utility model discloses a laser-guided puncture and tube placement rack device for an ultrasonic probe, which comprises a main body, wherein the main body comprises a non-adjustable rack, an adjustable rack and a rotating shaft, wherein the non-adjustable rack and the adjustable rack are connected via the rotating shaft, wherein the intersection of the non-adjustable rack and the adjustable rack is provided with the rotating shaft, wherein the non-adjustable rack and the adjustable rack are placed opposite to each other to form a rectangle, wherein the non-adjustable rack and the adjustable rack both have a small extension at one end of the short side of the rectangle, wherein the device further comprises a fixing screw, wherein the fixing screw is installed on the small extension, and wherein one end of the non-adjustable rack has a fixing groove.
[0025] As a preferred embodiment of the utility model, the device also includes a guide needle frame base, which is installed on the outside of the non-adjustable frame, parallel to the ultrasonic fan scanning surface, and can be connected to a fixed guide needle frame.
[0026] As a preferred embodiment of the utility model, the device further comprises a laser fixing frame, the laser fixing frame is installed on the outside of the adjustable frame, and the laser fixing frame can hold a detachable laser.
[0027] As a preferred embodiment of the present utility model, the device also includes a transverse axis needle guide frame base, which is installed on the outside of the non-adjustable frame and located at the short side of the rectangle, and can be connected to a fixed guide needle frame.
[0028] As a preferred embodiment of the present utility model, the main body is made of 3D printed nylon material.
[0029] As a preferred embodiment of the utility model, the non-adjustable frame is clamped on the ultrasonic probe through the fixing groove, the rotating shaft rotates, the device adjusts the fixing screws to make the four walls of the device fit with the ultrasonic probe, and the main body is fixed on the ultrasonic probe through the adjustment frame.
[0030] In a specific embodiment of the utility model, the main body is formed by connecting a non-adjustable frame and an adjustable frame through a rotating shaft, and the basic structures include a guide needle frame base, fixing screws, a laser fixing frame, and a detachable laser. The non-adjustable frame is clamped on the superficial probe through a fixing groove, and the rotating shaft is rotated to adjust the fixing screws and the adjusting frame so that the main body is fixed on the superficial probe. The guide needle frame or the laser can be fixed according to the operation situation.
[0031] The main structure is 3D printed using nylon material, and the base of the guide needle holder is integrated with the puncture holder, so that the base is parallel to the ultrasonic fan scan surface. When in use, the puncture holder is clamped on the superficial probe, and the fixing screws are adjusted to ensure that the four walls of the puncture holder fit the probe, and the longitudinal axis (fan scan surface) is parallel to the long end of the puncture holder. The probe surface is evenly coated with coupling agent and covered with a sterile bag. Select a guide needle holder with a suitable angle, connect it to the base and fix it on the puncture holder, and complete puncture and catheterization through ultrasound guidance; when the guide needle holder is not in use, a small laser can be installed on the puncture holder, and the puncture site can be found through ultrasound positioning, and the site can be marked with a laser.
[0032] The utility model adds a base parallel to the short end, and the guide needle holder can be combined therewith, so that longitudinal axis puncture under ultrasound guidance becomes possible, thereby increasing the function of the instrument.
[0033] The puncture frame is made of 3D printed nylon material, which can fit well with the superficial ultrasound probe, and is resistant to high temperatures of 140 degrees, corrosion, and can be sterilized by heat and plasma. Because it is wrapped in a sterile plastic cloth during use, it can also be simply wiped with ethanol and soaked for disinfection, which is convenient and quick.
[0034] It can be combined with the common sterile needle guide holders on the market to perform external and internal ultrasonic puncture, which improves the selectivity and application rate and is more suitable for difficult CVC and PICC vascular puncture and catheterization in critical care departments.
[0035] The puncture stand and the bracket can be used together or separately. It is easy to disassemble and firmly engage, avoiding excessive operations that affect the sterile area and improving the operation quality.
[0036] The laser is designed for extravascular needle insertion, which is more user-friendly for operation in narrow parts of the body (such as the neck and near the clavicle). The external needle insertion method also facilitates vascular puncture and examination for blood gas analysis in difficult patients.
[0037] Nylon material is light and convenient, has good elasticity, and can fit the ultrasound probe better by adjusting the fixing screws, avoiding damage to the probe by metal materials. Nylon material can withstand high temperatures of 140°C and can be sterilized using conventional hospital disinfection methods such as hot pressing, plasma, and ethylene oxide. 3D printing technology can be used for modeling and production with higher precision.
