Problems solved by technology

[0002] Puncture and fistula surgery, drainage surgery, and laparoscopic surgery, which require percutaneous puncture to establish a working channel, are performed in clinical treatment. At present, ordinary surgical instruments such as puncture needles, dilators, and working sheaths are traditionally used. Since the various instruments are not integrated, that is, they do not form a whole device, the deviation of the puncture depth and the expansion depth often occurs, causing complications, and the deviation of the insertion depth of the working sheath and the puncture depth often occurs, resulting in the failure of the establishment of the working channel or Fistula drainage failure, etc.

Embodiment 1

[0021] Percutaneous drainage or percutaneous fistula

[0022] First, the puncture needle consists of a needle core, a needle sheath, and a detachable syringe interface. Under the guidance of medical images (such as ultrasound, CT, X-ray, etc.), the puncture target (such as dilated renal pelvis, renal calyx, dilated bile duct, gallbladder, etc.) Bladder abscess, effusion, etc.) for puncture, pull out the puncture needle core, after the liquid sucked through the detachable syringe interface or X-ray contrast confirms that the puncture is successful, insert the safety guide wire from the needle sheath, remove the detachable With the syringe interface, fix the needle sheath, hold the needle sheath in one hand to keep the needle sheath fixed, and hold the innermost channel expansion tube along the guide wire and the needle sheath to expand the puncture channel with the other hand. The left port of the expansion tube reaches the needle sheath Stop the expansion when the tube body ma...

Embodiment 2

[0024] Laparoscopic surgery that requires percutaneous puncture to establish a working channel (such as percutaneous nephrolithotomy, percutaneous cholangioscopic surgery, cholecystoscopy, arthroscopy, etc., thoracoscopic surgery, etc.).

[0025] First, the puncture needle consists of a needle core, a needle sheath, and a detachable syringe interface. Under the guidance of medical images (such as ultrasound, CT, X-ray, etc.), the puncture target (such as dilated renal pelvis, renal calyx, dilated bile duct, gallbladder, etc.) Joints, pleural cavity with effusion, etc.) for puncture, pull out the puncture needle core, after the liquid sucked through the detachable syringe interface or X-ray contrast confirms that the puncture is successful, insert the safety guide wire from the needle sheath, remove the detachable Type syringe interface, fix the needle sheath tube, hold the needle sheath tube with one hand, keep the needle sheath tube fixed, and hold the innermost channel expans...

Abstract

The invention provides a multi-purpose percutaneous puncture channel construction and ostomy drainage device, which is composed of a needle sheath tube, a needle core, a detachable syringe interface, a guide wire, a multi-layer channel expansion tube, a working sheath tube and a drainage tube , the left end of the needle core has a needle core handle, the inner hole of the needle core handle is provided with a ring groove, the ring groove coincides with the left end of the detachable syringe interface and the left end of the needle sheath, the needle core is inserted in the needle sheath tube, detachable The syringe interface is tightly slidably arranged on the left end of the needle sheath, the right end of the needle sheath is provided with a convex ring, the innermost channel expansion tube is arranged outside the needle sheath, and its right end is connected with the convex ring, and the outermost channel A working sheath is also provided on the outside of the expansion tube, and a handle is provided at the left end of the working sheath. The inner diameter of the working sheath is consistent with that of the adjacent multi-layer channel expansion tube. Compared with the prior art, the device can reduce surgical complications, improve the success rate of surgery, reduce the labor intensity of medical personnel, and has good versatility and can be used for minimally invasive surgical treatment of various diseases.

Description

1. Technical field [0001] The invention relates to a manufacturing technique of surgical instruments, in particular to a multi-purpose percutaneous puncture tunnel construction and ostomy drainage device. 2. Background technology [0002] Puncture and fistula surgery, drainage surgery, and laparoscopic surgery, which require percutaneous puncture to establish a working channel, are performed in clinical treatment. At present, ordinary surgical instruments such as puncture needles, dilators, and working sheaths are traditionally used. Since the various instruments are not integrated, that is, they do not form a whole device, the deviation of the puncture depth and the expansion depth often occurs, causing complications, and the deviation of the insertion depth of the working sheath and the puncture depth often occurs, resulting in the failure of the establishment of the working channel or Fistula drainage failure, etc. This invention interlocks the mechanical structure of th...
