Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and more specifically, to a Y-shaped puncture needle seat for improving the patency of a guide wire. Background Art

[0002] Y-type puncture needle holder is generally used in medical treatment. It is a device that helps to fix the guide wire and ensures that the guide wire can smoothly enter deep tissues or blood vessels. The guide wire is used to guide and implant other instruments or devices, such as catheters, catheter electrodes, vascular stents, etc. In interventional surgery, the guide wire enters the body through the incision of the blood vessel or tissue, and is then pushed by the patient's own strength or other instruments to reach the treatment position or for examination.

[0003] In the related art, a puncture needle is used to puncture the patient's body, and then a guide wire is passed through the puncture needle into the body. For example, the patent with the prior art publication number CN217310507U provides a disposable Y-shaped arterial puncture needle. The device inserts the puncture needle body into the patient's body through the arrangement of the puncture needle body and the Y-shaped needle tail structure. A blood collection bag is provided at the tail end of the branch of the Y-shaped needle tail structure, and a diaphragm is provided in the Y-shaped tail end of the main path of the Y-shaped needle tail structure. After the arterial puncture is successful, the diaphragm blocks the blood from spraying outward, and the blood will flow into the blood collection bag, thereby keeping the surgical area dry and clean, and also protecting medical workers from the risk of occupational exposure.

[0004] Although the above-mentioned prior art solution can achieve the puncture effect through the setting of the puncture needle body and the Y-shaped needle tail structure, it still has the following defects: after the puncture needle enters the flesh, the inside of the needle tube will enter the flesh and blood tissue along with the blood flow, and the flesh and blood tissue will slowly accumulate at the needle head and block the needle head, affecting the advancement of the guide wire, causing the guide wire to be obstructed during its movement, affecting the intervention effect and efficiency.

[0005] In view of this, we propose a Y-shaped puncture needle seat for improving the patency of the guidewire. Utility Model Content

DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1 and Figure 2, a Y-shaped puncture needle seat for improving the patency of a guide wire, comprising a Y-shaped puncture needle tube 1;

[0029] The suction mechanism 4 is arranged at the other end of the suction pipe 3, and is used to provide power for suction.

[0030] Through the setting of the suction mechanism 4, if too much blood and flesh tissue accumulates inside the puncture needle 101, the suction mechanism 4 will generate a suction force inside the Y-shaped puncture needle tube 1, and the blood and flesh tissue inside the puncture needle 101 will enter the guide tube 2 through the suction force, and be collected by the blood bag 201, thereby improving the smoothness of the guide wire, achieving better puncture interventional treatment effects, and improving work efficiency.

[0031] Reference Figure 1 and Figure 3 A limiting ring plate 203 is fixedly arranged on the outer side of the other end of the guide tube 2, and a connecting ring 202 is threadedly connected to the outer side of the other end of the guide tube 2. A sealing gasket is arranged between the connecting ring 202 and the limiting ring plate 203, and a blood bag 201 is fixedly arranged on the other end of the connecting ring 202.

[0032] The outflowing blood and flesh enter into the blood bag 201 through the guiding tube 2 and are collected. The setting of the connecting ring 202 facilitates the disassembly and installation of the blood bag 201.

[0033] Reference Figure 1 , Figure 2 and Figure 3The other end of the Y-shaped puncture needle tube 1 is provided with a puncture needle 101, a handle 104 is fixedly provided on the outside of the Y-shaped puncture needle tube 1, a one-way air valve 102 is provided on the outside of the Y-shaped puncture needle tube 1, and a silicone plug 103 is inserted into one end of the Y-shaped puncture needle tube 1. The suction mechanism 4 includes a driving gear 401, and a lifting gear plate 403 is meshed on the outside of the driving gear 401. A connecting frame 404 is fixedly provided on the other side of the lifting gear plate 403, and a suction piston 405 is fixedly provided at the bottom end of the connecting frame 404. The suction piston 405 is slidably provided inside the suction tube 3, and support plates 406 are fixedly provided on both sides of the connecting frame 404. The bottom of the support plate 406 A telescopic rod 407 and a return spring 408 are fixedly provided at one end, and a support plate 406 is fixedly provided at the other end of the telescopic rod 407 and the return spring 408. A side plate 410 is fixedly provided on one side of the support plate 406, and a fixed outer frame plate 409 is fixedly provided between the side plates 410. The lifting gear plate 403 and the connecting frame 404 are slidably provided on one side of the fixed outer frame plate 409, and the fixed outer frame plate 409 is fixedly provided on the outside of the suction pipe 3. A short rod is fixedly provided through the middle of one end of the driving gear 401, and the short rod is rotatably provided between the side plates 410. A knob 402 is fixedly provided at one end of the short rod, and anti-slip grooves are provided on the outside of the knob 402.

[0034] The medical staff grasps the handle 104 with their hands and puts their thumbs on the outside of the knob 402 in the suction mechanism 4. The thumb moves downward to rotate the knob 402. The rotation of the knob 402 drives the driving gear 401 to rotate through the short rod. The rotation of the driving gear 401 allows the lifting gear plate 403 to rise. The lifting of the lifting gear plate 403 drives the connecting frame 404 and the suction piston 405 to rise. The suction piston 405 moves upward on the inner side of the suction tube 3 and generates suction inside the Y-shaped puncture needle tube 1, thereby drawing the blood and flesh accumulated inside and around the puncture needle 101 into the inside of the Y-shaped puncture needle tube 1 to achieve the effect of clearing the blockage.

[0035] Working principle: the puncture needle 101 is inserted into the patient's body, and the blood and flesh entering through the puncture needle 101 will enter the blood bag 201 through the diversion tube 2. The blood bag 201 can be installed at one end of the diversion tube 2 through the connecting ring 202 for going out, and it is also easy to disassemble, so that the operating room can be kept clean and tidy. The Y-shaped puncture needle tube 1 and the diversion tube 2 are transparent, and the medical staff can observe the internal conditions of the Y-shaped puncture needle tube 1 and the diversion tube 2 with the naked eye. If the inside of the puncture needle 101 is blocked, the medical staff grasps the handle 104 with his hand, puts the thumb on the outside of the knob 402 in the suction mechanism 4, and moves the thumb downward to rotate the knob 402. The rotation of the knob 402 drives the driving gear 401 to rotate through the short rod, and the rotation of the driving gear 401 allows the lifting gear plate 403 to rise. The lifting gear plate 403 drives the connecting frame 404 and the suction piston 405 to rise, and the suction piston 405 moves upward on the inner side of the suction tube 3. The Y-shaped puncture needle tube 1 generates suction force, so that the blood and flesh accumulated in the puncture needle head 101 are drawn into the Y-shaped puncture needle tube 1, and then collected by the blood bag 201 through the guide tube 2. When the lifting gear plate 403, the connecting frame 404 and the suction piston 405 are raised, the telescopic rod 407 and the return spring 408 are extended. After one suction work is completed, the finger leaves the knob 402, and the lifting gear plate 403, the connecting frame 404 and the suction piston 405 are lifted. It will return to its original position through the elastic force of the return spring 408, and the suction piston 405 will move downward. When the suction piston 405 descends, the gas inside the Y-type puncture needle tube 1 will be discharged from the one-way air valve 102 to prevent affecting the puncture effect. After cleaning the flesh and blood tissue around the puncture needle 101, the silicone plug 103 is removed, and the guide wire is inserted into the interior of the Y-type puncture needle tube 1 for use, so as to achieve better puncture interventional treatment effects and improve work efficiency.
