Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a closed thoracic drainage trocar and a using method thereof. Background Art

[0002] The current structure design of the trocar is unreasonable. During the drainage process, first, the trocar is used for puncture, and then the drainage tube is inserted. The insertion of the tube and the puncture are carried out separately, which will inevitably cause the wound to come into contact with the outside world, bringing a risk of infection to the patient. Moreover, in order to ensure smooth drainage, the end of the existing drainage tube adopts a pig-tail structure, so that the drainage holes are located inside the pig-tail. Although it can drain smoothly, the pig-tail structure is not conducive to repeated insertion of the tube. The patient not only suffers great pain but also increases the clinical medical cost. Therefore, a closed thoracic drainage trocar and a using method thereof are proposed. Summary of the Invention

[0003] To solve the above at least one technical defect, the present invention provides a closed thoracic drainage trocar, including a drainage tube. A plurality of drainage grooves penetrating the inner wall are evenly opened on the outer wall at the bottom end of the drainage tube. A fixed valve is fixedly connected to the outer wall at the top end of the drainage tube. A three-way valve is fixedly connected to the top end of the drainage tube. An inner core is arranged inside the drainage tube. The inner core includes a puncture needle at the bottom end inside the drainage tube. The top end of the drainage groove is fixedly connected with a drainage fin. The bottom end of the drainage fin is fixedly connected with the top edge of the puncture needle. A connecting rod is integrally connected to the middle of the top end of the puncture needle. The top end of the connecting rod is fixedly connected with a piston located inside the top end of the three-way valve. The top of the piston is fixedly connected with a control ball handle.

[0004] Further, a sealing outer tube is arranged around the drainage tube. The top end of the sealing outer tube is fixedly connected to the outer wall of the drainage tube below the fixed valve. The bottom end of the sealing outer tube is fixedly connected with a transparent suction cup, and the inside of the sealing outer tube is evacuated.

[0005] Further, an annular control groove is formed between the piston and the control ball handle, and a buckle is clamped inside the control groove.

[0006] Further, the buckle includes a semi-circular clamping block one and a semi-circular clamping block two that fit the control groove. The ends of the semi-circular clamping block one and the semi-circular clamping block two are hinged together. The outer wall of the other end of the semi-circular clamping block one is hinged with an arc-shaped locking block. A locking groove is opened on the outer wall of the other end of the semi-circular clamping block two, and the inner wall of the arc-shaped locking block fits the locking groove.

[0007] Further, another port of the three-way valve is connected with an extension tube through a standard Luer connector. A rolling switch is arranged on the extension tube, and the end of the extension tube is connected with a drainage bottle.

[0008] Further, the inner diameter of the drainage tube is equal to the top diameter of the puncture needle, and the diameter of the connecting rod is smaller than the top diameter of the puncture needle.

[0009] Furthermore, a hard ring is provided on the inner wall of the bottom end of the drainage tube.

[0010] Furthermore, the outer wall of the drainage tube is provided with scales.

[0011] Furthermore, the drainage bottle is a disposable drainage bag.

[0012] A method for using a chest closed drainage puncture device is used for a chest closed drainage puncture device. Pre-sterilization: spraying medical alcohol on the adsorption surface of a transparent suction cup and the puncture area on the patient; fixing the suction cup: adsorbing the transparent suction cup on the puncture area on the patient; puncture operation: holding the control ball handle and pushing it forward to make the puncture needle pierce the central area of ​​the transparent suction cup and then pierce the patient, while observing the patient's condition, and at the same time, under the push of the transparent suction cup, the folds of the sealed outer tube are stacked together; the needle tip flap is opened: Holding the control ball handle in one hand and the fixed flap in the other, pull the piston out from the inside of the three-way valve to expose the control groove. At the same time, retract the puncture needle into the bottom end of the drainage tube. At the same time, the top end of the puncture needle supports the bottom end of the drainage flap. Under the action of the supporting force, the middle part of the drainage flap is bent outward to open the tissue around the drainage groove, making the drainage groove less likely to be blocked. Then clamp the buckle to the control groove and observe the patient's condition at the same time; Tape fixation: Use the adhesive strip to stick the fixed flap tightly and fix it, and reinforce the transparent suction cup at the same time. Beneficial Effects

[0013] Compared with the prior art, the top of the puncture needle in the present invention will squeeze the drainage flap, causing the middle part of the drainage flap to bulge outward to support the surrounding tissue. After the middle part of the drainage flap bulges outward, it can play a fixing role on the one hand, and on the other hand, it can prevent the drainage groove from being blocked, effectively avoiding the problem of poor drainage. At this time, the puncture needle is completely retracted into the interior of the drainage tube, which can effectively avoid secondary damage to the patient by the puncture needle, and the drainage and puncture operations can be completed at one time, which can reduce the patient's pain.

[0014] Spraying medical alcohol on the adsorption surface of the transparent suction cup for sterilization can also effectively improve the adsorption force of the transparent suction cup. The puncture needle pierces the middle of the transparent suction cup, and then punctures the patient. During the puncture, the entire puncture needle, drainage tube and the patient's wound are all in an environment isolated from the outside world, which can effectively reduce the risk of external bacterial infection.

Detailed implementation mode

[0027] Please refer to Figures 1 to 10 ; This embodiment provides a closed thoracic drainage puncture device. Referring to Figures 1 to 5 , it includes a drainage tube 1. A plurality of drainage grooves 101 penetrating the inner wall are evenly formed on the outer wall of the bottom end of the drainage tube 1. A fixed flap 103 is fixedly connected to the outer wall of the top end of the drainage tube 1. A three-way valve 104 is fixedly connected to the top end of the drainage tube 1. An inner core 2 is arranged inside the drainage tube 1. The inner core 2 includes a puncture needle 201 located inside the bottom end of the drainage tube 1. A drainage fin 102 is fixedly connected to the top end of the drainage groove 101. The bottom end of the drainage fin 102 is fixedly connected to the top edge of the puncture needle 201. A connecting rod 202 is integrally connected to the middle of the top end of the puncture needle 201. The top end of the connecting rod 202 is fixedly connected to a piston 203 located inside the top end of the three-way valve 104. A control ball handle 204 is fixedly connected to the top of the piston 203.

[0028] During specific implementation, the puncture needle 201 is inserted forward, and the traction and drainage fin 102 pulls the drainage tube 1 to move forward. When it is inserted to an appropriate position, the control ball handle 204 is pulled, so that the piston 203 moves outward from the inside of the three-way valve 104. At the same time, the connecting rod 202 pulls the puncture needle 201 and retracts into the inside of the drainage tube 1. At this time, the drainage tube 1 is fixed by the fixed valve 103. At the same time, the drainage tube 1 is also subject to the frictional force from the tissue. When the puncture needle 201 moves back, although the drainage tube 1 will move outward slightly, the amount of movement is not large. At the same time, the top of the puncture needle 201 will squeeze the drainage fin 102, causing the middle part of the drainage fin 102 to bulge outward and lift the surrounding tissue. After the middle part of the drainage fin 102 bulges outward, on the one hand, it can play a fixing role, and on the other hand, it can prevent the drainage groove 101 from being blocked, effectively avoiding the problem of unsmooth drainage. And at this time, the entire puncture needle 201 retracts into the inside of the drainage tube 1, which can effectively avoid secondary injury to the patient by the puncture needle 201, and the drainage and puncture operations can be completed at one time, reducing the pain of the patient.

[0029] Further, referring to Figure 6 , a sealing outer tube 3 is provided on the outer periphery of the drainage tube 1. The top end of the sealing outer tube 3 is fixedly connected to the outer wall of the drainage tube 1 below the fixed valve 103. The bottom end of the sealing outer tube 3 is fixedly connected with a transparent suction cup 301, and the inside of the sealing outer tube 3 is evacuated.

[0030] During specific implementation, when not in use, the setting of the sealing outer tube 3 enables the entire drainage tube 1 to be in a sterile vacuum environment, which can reduce contact with the outside world and lower the risk of infection of the patient by external bacteria.

[0031] When in use, the adsorption surface of the transparent suction cup 301 is sprayed with medical alcohol for sterilization, and at the same time, the adsorption force of the transparent suction cup 301 can be effectively improved. The puncture needle 201 pierces through the middle of the transparent suction cup 301, and then the patient is punctured. When puncturing, the entire puncture needle 201, the drainage tube 1 and the wound of the patient are all in an environment isolated from the outside world, which can effectively reduce the risk of external bacterial infection.

[0032] The adsorption surface of the transparent suction cup 301 is sprayed with anesthetic. When the drainage tube 1 pierces through the middle of the transparent suction cup 301, the sprayed anesthetic will be evenly distributed on the outer walls of the puncture needle 201 and the drainage tube 1, thereby reducing the pain of the patient.

[0033] Further, referring to Figure 2 earring Figure 4 , an annular control groove 205 is formed between the piston 203 and the control ball handle 204, and a buckle 4 is clamped inside the control groove 205.

[0034] In specific implementation, when pulling the control handle 204 to move the piston 203 outwards from the inside of the three-way valve 104, the buckle 4 is inserted into the control groove 205, with the top end of the buckle 4 supporting at the bottom of the control handle 204 and the bottom end of the buckle 4 supporting at the top end of the three-way valve 104. At this time, the piston 203 is limited inside the three-way valve 104.

[0035] Further, referring to Figures 7 to 10 , the buckle 4 includes a semi-circular block one 401 and a semi-circular block two 402 that fit into the control groove 205. The ends of the semi-circular block one 401 and the semi-circular block two 402 are hinged together. An arc-shaped locking block 403 is hinged on the outer wall of the other end of the semi-circular block one 401, and a locking groove 421 is formed on the outer wall of the other end of the semi-circular block two 402. The inner wall of the arc-shaped locking block 403 fits with the locking groove 421.

[0036] In specific implementation, when buckling the buckle 4, first press the semi-circular block one 401 into the control groove 205, then press the semi-circular block two 402 into the other half of the control groove 205, and then press the arc-shaped locking block 403 into the locking groove 421 to complete the buckling.

[0037] Further, another port of the three-way valve 104 is connected with an extension tube 5 through a standard Luer connector. A rolling switch is provided on the extension tube 5, and the end of the extension tube 5 is connected with a drainage bottle 6.

[0038] In specific implementation, both the extension tube 5 and the drainage bottle 6 are of the prior art.

[0039] Further, the inner diameter of the drainage tube 1 is equal to the top diameter of the puncture needle 201, and the diameter of the connecting rod 202 is smaller than the top diameter of the puncture needle 201.

[0040] In specific implementation, the diameter of the connecting rod 202 is smaller than the top diameter of the puncture needle 201, so that there is enough clearance between the outer wall of the connecting rod 202 and the inner wall of the drainage tube 1 for drainage.

[0041] Further, referring to Figure 5 , a rigid ring 105 is provided on the inner wall of the bottom end of the drainage tube 1.

[0042] In specific implementation, the bottom end of the drainage tube 1 can form an annular support through the rigid ring 105.

[0043] Further, scales are provided on the outer wall of the drainage tube 1.

[0044] In specific implementation, the insertion depth of the drainage tube 1 can be observed through the scales.

[0045] Further, the drainage bottle 6 is a disposable drainage bag.

[0046] In specific implementation, the drainage bottle 6 is a disposable drainage bag, which facilitates the integration into disposable medical consumables.

[0047] A method for using a closed thoracic drainage trocar, which is applied to a closed thoracic drainage trocar. Pre-sterilization: Sprinkle medical alcohol on the adsorption surface of the transparent suction cup 301 and the puncture area on the patient's body. Suction cup fixation: Adsorb the transparent suction cup 301 on the puncture area on the patient's body. Puncture operation: Hold the control ball handle 204 and push it forward, so that the puncture needle 201 pierces the central area of the transparent suction cup 301 and then penetrates into the patient's body. At the same time, observe the patient's condition. Under the push of the transparent suction cup 301, the sealing outer tube 3 folds and stacks together. Opening of the inner retracted needle fin: Hold the control ball handle 204 with one hand and the fixed valve 103 with the other hand. Pull the piston 203 out of the inside of the three-way valve 104 to expose the control groove 205. At the same time, retract the puncture needle 201 to the bottom inside of the drainage tube 1. The top of the puncture needle 201 supports the bottom of the drainage fin 102. Under the action of the supporting force, the middle part of the drainage fin 102 bends outward and opens to expand the tissue around the drainage groove 101, making the drainage groove 101 less likely to be blocked. Then clamp the buckle 4 to the control groove 205 and observe the patient's condition at the same time. Tape fixation: Fix the fixed valve 103 tightly with an adhesive tape and reinforce the transparent suction cup 301 at the same time.
