Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a device and method for fixing a thoracoscopic needle. Background Art

[0002] In clinical medical practice, when a patient has chest effusion or hydropneumothorax, the doctor will perform thoracentesis on the patient to extract the effusion or gas for examination. Thoracentesis is a technical means used clinically to diagnose and treat patients with pleural effusion (i.e. pneumothorax). It has the functions of extracting pleural effusion for testing, extracting pleural effusion and gas to relieve patient symptoms, extracting pus for pleural lavage to treat empyema, and injecting antibiotics and other drugs into the thoracic cavity. During this technical operation, the operator will connect the thoracentesis needle to the fluid extraction syringe or the drug-loaded syringe, and close the switch between the two to ensure a tight closure without air leakage.

[0003] During thoracentesis, a thoracentesis needle is required to extract fluid or gas from the patient's pleural cavity. During the entire operation, it is necessary to ensure that the needle tip of the thoracentesis needle is only in the thoracic cavity to prevent damage to important organs or blood vessels such as the heart and lungs. Medical accidents may occur if the patient is not careful during the operation. The invention with application number CN202322047661.7 discloses a thoracentesis needle that is easy for one person to operate. This thoracentesis needle uses a valve body to drive an internal rotary plate to open and close the surgical channel, avoiding the disadvantages of cumbersome storage, increased surgical operations, and increased number of complete thoracentesis. It also ensures simple operation for the operator. At the same time, due to the simple integrated structure, the needle body can be kept relatively fixed to the other parts of the device by tightening the threads. However, the thread tightening method of this device is not easy to get stuck when the threads are tightened too loosely, causing the needle body to loosen. However, if it is tightened too much, the needle body structure will be damaged. The overall structure is relatively complex and requires multi-stage assembly, which increases production costs. At the same time, the operation steps are relatively cumbersome and require two-handed operation, leaving room for further improvement. Summary of the Invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a device and method for fixing a thoracotomy needle to solve the above problem.

[0005] To achieve the above-mentioned purpose, a device for fixing a thoracoscopic needle is provided, comprising a U-shaped base, a U-shaped flip cover is fixedly connected to the upper middle part of the U-shaped base, a flip shaft is rotatably connected to the middle part of the U-shaped flip cover, a linkage bracket is fixedly connected to the middle part of the flip shaft, a needle body fixing clip is fixedly connected to the end of the linkage bracket close to the U-shaped flip cover, a third bending groove is provided in the middle part of the linkage bracket, and a bracket buckle is provided on both sides of the third bending groove in the inner middle part of the linkage bracket.

[0006] According to the device for fixing a thoracoscopic needle, first bending grooves are provided at the connection points on both sides of the U-shaped flap and the U-shaped base.

[0007] According to the device for fixing a thoracoscopic needle, a fixing tape and a suture hole are provided at the bottom of the U-shaped base.

[0008] According to the device for fixing a thoracoscopic needle, one end of the linkage bracket away from the needle body fixing clamp is fixedly connected to the U-shaped base.

[0009] According to the device for fixing a thoracoscopic needle, a second bending groove is provided at one end of the linkage bracket close to the U-shaped base. By being arranged on one side of the bending, the final bending angle can be limited while reducing the bending stress.

[0010] According to the device for fixing a thoracoscopic needle, a fixing card is provided at the middle part of the inner side of one end of the needle body fixing clip, and a T-shaped slot is provided at the middle part of the end of the needle body fixing clip away from the fixing card, and the outer depth of the T-shaped slot is greater than the end length of the fixing card, so that the end of the fixing card can be stuck in the T-shaped slot without exposing the end of the fixing card to the outside, and will not block the fixing card from passing through the slot body of the T-shaped slot when the fingers cover the position of the T-shaped slot, which is convenient for pinching and fixing with fingers.

[0011] According to the device for fixing a thoracoscopic needle, both ends of the U-shaped base are provided with a card slot, and both sides of the U-shaped flip cover are provided with a card slot corresponding to the card slot; According to the device for fixing a thoracoscopic needle, the U-shaped base is divided into two fixedly connected parts, the upper part, the U-shaped flip cover and the linkage bracket are an integrated structure, and all are made of polyvinyl chloride material.

[0012] According to the device for fixing a thoracoscopic needle, the distance between the first bending groove and the flip axis corresponds to the spacing between the second bending groove and the third bending groove, and a parallelogram structure can be formed.

[0013] A method for fixing a thoracotomy needle, comprising the following steps: S1. Before the procedure, determine the thoracentesis location based on the examination results and mark it; S2. During preparation, remove the instrument kit in a sterile environment and inspect it for leaks. After ensuring there is no contamination, open the kit and remove the thoracentesis needle and fixation device. S3. After inspecting the thoracoscopic needle and fixation device for defects, place the relevant instruments on the instrument table and perform preoperative disinfection preparations. S4. After disinfection, connect the thoracentesis needle to the corresponding tubing and perform the thoracentesis at the marked location. S5. After the thoracentesis is completed, the operator can fix the thoracentesis needle with one hand, pick up the edge of the device with the thumb and middle finger of the other hand, and pick the middle part of the U-shaped flap with the index finger, then the U-shaped flap of the fixing device can be separated from the U-shaped base; S6. When the U-shaped flap is turned up, the linkage bracket connected to the U-shaped flap through the turning shaft above the U-shaped base will be bent from the designated position under the restriction of the bending groove, forming a three-dimensional bracket structure. At this time, support the lower part of the U-shaped base with the ring finger and continue to exert force with the index finger, then the bracket buckles under the linkage bracket can be buckled with each other, and the unfolding and fixing of the three-dimensional bracket can be completed with one hand; S7. When the fixing device is unfolded and fixed, due to the parallelogram structure formed by the linkage bracket, the overall posture of the needle body fixing clip connected to the end of the linkage bracket is always parallel to the U-shaped base. At this time, move the fixing device, embed the thoracentesis needle fixed by the other hand into the U-shaped clamping groove of the needle body fixing clip, then pinch the end of the needle body fixing clip with the thumb and index finger, and make the fixing buckle into the T-shaped groove to fix the needle body, and then fix the U-shaped base on the affected area.

[0014] The above solution has at least one of the following beneficial effects: 1. The present invention is provided with a U-shaped base and a U-shaped flap, which cooperate with the linkage bracket and the needle body fixing clip. After the needle is inserted, the U-shaped flap can be opened with one hand. Under the limit of the turning shaft, the bending of the linkage bracket will cause the needle body fixing clip to remain parallel to the U-shaped base. When the bracket buckles are buckled with each other, the U-shaped groove of the needle body fixing clip can be clamped onto the needle body, and pinching the end of the needle body fixing clip can fix the needle body. The structure is simple and the operation is convenient, which enhances the practicability of the device.

[0015] 2. The present invention is provided with a linkage bracket. When the U-shaped flap is turned up, by using the setting of the bending groove, the linkage of the needle body fixing clip can be formed by determining its own bending direction. Cooperating with the bracket buckles, the effect of fixing immediately after folding can be achieved, and the unfolding and fixing operations can be completed with one hand, which enhances the practicability of the device.

[0020] A method for fixing a thoracic puncture needle, the method steps are as follows: S1. Before the operation, determine the thoracic puncture operation position according to the examination situation, and make marks for marking work; S2. When preparing, take out the instrument package in a sterile environment, check whether the instrument package leaks, and after ensuring no leakage and pollution, open the instrument package and take out the thoracic puncture needle and the fixing device inside together; S3. After detecting whether the thoracic puncture needle and the fixing device are defective, place the relevant instruments on the instrument table and perform the preliminary surgical disinfection preparation work; S4.

Under the limitation of the rotation axis 5, the bending of the linkage bracket 3 will cause the needle body fixing clip 4 to maintain a position parallel to the U-shaped base 1. When the bracket buckles 9 are buckled with each other, the needle body fixing clip 4 can be snapped onto the needle body. At this time, by squeezing the end of the needle body fixing clip 4, the needle body can be fixed. When the U-shaped flip cover 2 is flipped up, the linkage bracket 3 can, by means of the arrangement of the bending groove, form the linkage of the needle body fixing clip 4 by determining its own bending direction. In cooperation with the bracket buckles 9, the effect of being fixed immediately after flipping can be achieved, and the unfolding and fixing operations can be completed with one hand, with a simple structure and convenient operation.
