Description

Technical Field

[0001] This utility model belongs to the field of side-hole catheter technology, and specifically relates to a side-hole catheter for interventional surgery. Background Technology

[0002] A side-port catheter is a medical catheter with side holes in its wall. These side holes allow for lateral delivery and drainage of substances. They are made of various materials, possess good flexibility and biocompatibility, and the position of the side holes can be flexibly adjusted during operation. They have wide clinical applications, primarily used for the precise delivery of drugs and contrast agents in interventional procedures; for drainage therapy, to fully drain accumulated fluid and pus; and for nutritional support, delivering nutrient solutions to patients through the side holes, providing effective support for disease diagnosis and treatment.

[0003] When traditional catheters are used with syringes and other auxiliary instruments mounted on their surfaces, the process of removing and replacing these instruments mid-operatively is quite troublesome due to the threaded connection, which hinders the quick replacement of these instruments and may potentially affect the operation. Utility Model Content

[0004] The purpose of this invention is to provide a side-hole catheter for interventional surgery, which has the advantage of enabling quick assembly and disassembly of auxiliary instruments on the catheter surface.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a side-hole catheter for interventional surgery, comprising a catheter, one end of the surface of the catheter having a hole, the other end of the catheter being fixedly connected to a connecting shell, a fixing shell being slidably connected to the surface of the connecting shell, and a sealing ring being fixedly connected to the center of the interior of the fixing shell.

[0006] The above technical solution allows the guidewire and microcatheter to easily enter the vascular branch, and the sealing ring is used to seal the connection between the syringe and the catheter to prevent leakage.

[0007] The present invention is further configured such that upright plates are adhered to both sides of the connecting shell, and two sets of spring push rods are bolted inside the upright plates.

[0008] The above technical solution is adopted: the spring push rod is used to push the positioning block to be positioned inside the housing.

[0009] The present invention is further configured such that the piston ends of the two sets of spring push rods are bolted together with positioning blocks, and the fixed shells are glued to both sides, and the positioning blocks are detachably connected to the fixing blocks.

[0010] By adopting the above technical solution, the positioning block and the locking shell can fix the position of the fixed shell and the connecting shell.

[0011] The present invention is further configured such that mounting plates are adhered to both sides of the connecting shell, and a rotating rod is fixedly connected inside the mounting plate.

[0012] The above technical solution is adopted: the rotating rod is used for the rotation of the flip plate.

[0013] The present invention is further configured such that a flip plate is rotatably connected to the surface of the rotating rod, and torsion springs are sleeved at both ends of the surface of the rotating rod, and both ends of the torsion springs are connected between the flip plate and the mounting plate through spring fixing members.

[0014] The above technical solution is adopted: a torsion spring is used to drive the rotating flip plate to reset.

[0015] The present invention is further configured such that a clamping plate is glued to one end of one side of the flip plate, a rubber pad is glued to the inner wall of the clamping plate, and Velcro is glued to both sides of the clamping plate.

[0016] Using the above technical solution: when the flip plate rotates, it will cause the clamping plate to clamp onto the surface of the syringe, thereby fixing the syringe and the catheter together. The rubber pad is used to prevent the syringe from slipping when it is clamped and fixed. When two sets of clamping plates clamp onto the surface of the syringe at the same time, the corresponding two sets of Velcro will stick together to prevent the syringe from falling off.

[0017] In summary, this utility model has the following beneficial effects:

[0018] When the syringe tip is passed through the sealing ring and pushed forward, the fixed shell moves downward on the surface of the connecting shell. During this downward movement, because the sides of the retaining shell are beveled and made of smooth tempered glass, the retaining shell presses against the positioning block, causing the positioning block to move using a spring-loaded rod. When the retaining shell continues to move to the appropriate position, the spring-loaded rod pushes the positioning block to be positioned inside the retaining shell, thus fixing the connection between the fixed shell and the connecting shell. During the movement, the retaining shell pushes one end of the flip plate, causing the flip plate to rotate on the rotating rod surface. When the flip plate rotates, it causes the clamping plate to clamp onto the surface of the syringe, thus fixing the syringe and the tubing together. The rubber pad is used to prevent the syringe from slipping when it is clamped and fixed. When both sets of clamping plates clamp onto the surface of the syringe at the same time, the corresponding two sets of Velcro will stick together to prevent the syringe from falling off. When the syringe is removed, because the sides of the retaining shell are beveled, the fixed shell can be pulled up. The torsion spring is used to drive the rotated flip plate to return to its original position, achieving the effect of quick assembly and disassembly of the syringe and tubing.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1:

[0025] refer to Figure 1-4 A side-hole catheter for interventional surgery includes a catheter 1, one end of the surface of the catheter 1 has a hole 2, the other end of the catheter 1 is fixedly connected to a connecting shell 301, a fixing shell 302 is slidably connected to the surface of the connecting shell 301, and a sealing ring 303 is fixedly connected to the middle of the interior of the fixing shell 302.

[0026] Furthermore, upright plates 304 are bonded to both sides of the connecting shell 301, and two sets of spring push rods 305 are bolted inside the upright plates 304.

[0027] Furthermore, the piston ends of the two sets of spring push rods 305 are bolted together with positioning blocks 306, and the fixed shell 302 has clips 307 glued to both sides, and the clips 307 and positioning blocks 306 are detachably connected.

[0028] Furthermore, mounting plates 308 are glued to both sides of the connecting shell 301, and rotating rods 309 are fixedly connected inside the mounting plates 308;

[0029] Furthermore, a flip plate 311 is rotatably connected to the surface of the rotating rod 309, and torsion springs 310 are sleeved on both ends of the surface of the rotating rod 309. Both ends of the torsion springs 310 are connected between the flip plate 311 and the mounting plate 308 through spring fixing members.

[0030] Furthermore, a clamping plate 312 is glued to one end of one side of the flip plate 311, a rubber pad 313 is glued to the inner wall of the clamping plate 312, and Velcro 314 is glued to both sides of the clamping plate 312.

[0031] Brief description of usage: When the syringe tip is passed through the sealing ring 303 and pushed forward, the fixing shell 302 will move downward on the surface of the connecting shell 301. During the downward movement, because the two sides of the retaining shell 307 are beveled and made of tempered glass, which is relatively smooth, when the retaining shell 307 presses against the positioning block 306, the positioning block 306 will move using the spring push rod 305. When the retaining shell 307 continues to move to the appropriate position, the spring push rod 305 will push the positioning block 306 to be positioned inside the retaining shell 307, thereby fixing the connection between the fixing shell 302 and the connecting shell 301. Furthermore, during the movement, the retaining shell 307 will push the flip plate 31. 1. At one end, the flip plate 311 rotates on the surface of the rotating rod 309. When the flip plate 311 rotates, it will drive the clamping plate 312 to clamp the surface of the syringe, thereby fixing the syringe and the catheter 1 together. The rubber pad 313 is used to prevent the syringe from slipping when it is clamped and fixed. When both sets of clamping plates 312 clamp the surface of the syringe at the same time, the corresponding two sets of Velcro 314 will stick together to prevent the syringe from falling off. When the syringe is removed, since the two sides of the retaining shell 307 are inclined, the fixing shell 302 can be pulled up. The torsion spring 310 is used to drive the flip plate 311 to reset after rotation, which achieves the effect of facilitating quick assembly and disassembly of the syringe and the catheter 1.
