Percutaneous traction and puncture device

Abstract

The present invention relates to a percutaneous traction and puncture device. The percutaneous traction and puncture device comprises a traction needle, a percutaneous traction catheter, an extension rod and a spring; the traction needle is syringe needle shaped, the head of the traction needle is provided with a line hooking groove, and the tail of the traction needle is provided with a traction needle handle; the percutaneous traction catheter is cylinder-shaped with two ends opened for sleeving the traction needle, the tail of the percutaneous traction catheter is provided with a sleeve handle for holding and rotating to adjust directions, one side of the central section of the percutaneous traction catheter is provided with a traction rope placing groove through which a recycling line passes, the other side of the central section of the percutaneous traction catheter is provided with a groove for locking the extension rod, the top of the percutaneous traction catheter is provided with a spring placing groove for fixing the spring, and the side edge of the spring placing groove is provided with a fixing hole for fixing the extension rod; and one end of the extension rod is provided with an extension pipe movable hole, the other end of the extension rod is provided with a traction rope fixing hole and a suture traction port, one end of the recycling line is fixed to the traction rope fixing hole, and the extension rod rotates around the extension pipe movable hole and clamped to an outer wall of the percutaneous traction catheter. The percutaneous traction and puncture device has the beneficial effects that the percutaneous traction and puncture device is simple in structure and convenient to use, minimally invasive percutaneous puncture can be achieved, and traction force and directions can be easily controlled.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a device for percutaneously puncturing into a body cavity during an operation and guiding and pulling medical sutures in the body cavity. Background technique [0002] During surgery, especially laparoscopic surgery, it is often necessary to pull the organs or tissues in the body cavity in a specific direction to expand the surgical field of view and assist the surgical operation. Now clinically commonly used methods are to use retractors, clamps, and bare hands to perform corresponding traction. The newer method can fix medical sutures on specific tissue organs for traction. For example, during liver resection, medical sutures are sewed through a specific location near the liver tissue to be cut, and the sutures are pulled in a specific direction to assist in the completion of the operation. During the laparoscopic operation, due to the limitation of the operating equipment, t...

Problems solved by technology

During the laparoscopic operation, due to the limitation of the operating equipment, the operating instruments can only be operated through a few operating holes. If the traction of the tissue to be operated can be increased, it will have more auxiliary effects on the operation, but Under the current technology, the tissue can only be pulled and supported by instruments that can only be accessed through the operation hole

The current tissue organ traction operation under endoscopy has the following shortcomings: 1. It needs to use instruments for operation, which occupies the operating instruments, increases the difficulty of operation, and may need to increase the number of operation holes; , can only be pulled in one direction through the skin or through the operation hole. When the pulling direction needs to be changed, it needs to be punctured again, which increases the operation steps and damage; 3. The poor effect of tissue pulling will increase the difficulty of the operation
