Memory alloy detachable hemostatic forceps device

Abstract

The invention provides a memory alloy type separable hemostatic forceps device, comprising: a collet, including a rotating forceps head and a fixed forceps head connected by a memory alloy wire, and a tail pipe fixed with a connecting part of the rotating forceps head and the fixed forceps head; The assembly includes a first sleeve with a tail pipe inserted at the end, a push rod passing through the inside of the first sleeve and used to push the chuck, a liquid nitrogen exchange bin arranged at the front end of the first sleeve, and a The liquid nitrogen circulation pipe on the upper and lower sides of the inner wall of a set of pipes and connected with the liquid nitrogen exchange chamber, the restriction ring arranged at the end of the liquid nitrogen exchange chamber, and the first coil wound around the liquid nitrogen circulation pipe arranged between the restriction ring and the push rod. Electric heating wire; and a pliers assembly, including a second sleeve formed by a hollow section at the front end for inserting the tail pipe after use and a solid section arranged behind the hollow section, and a second sleeve arranged at the position of the tail rod and attached to the first sleeve. The second heating wire of the inner wall of the hollow part of the two sleeves. The invention has the advantages of low cost, simple principle, convenient use and good hemostatic effect.

Description

technical field [0001] The invention relates to a hemostatic forceps, in particular to a memory alloy type separable hemostatic forceps device. Background technique [0002] Minimally invasive surgery refers to surgery that causes minimal trauma to the human body during surgery, and is various types of surgery that use laparoscopy or tiny incisions for treatment. Traditional surgical incisions are particularly large, and at the same time, due to the extensive separation of tissues, more muscles, blood vessels and corresponding nerves are damaged, which is likely to cause complications. Compared with traditional surgery, minimally invasive surgery has the characteristics of smaller wound, less pain, faster recovery, shorter hospital stay and less bleeding, which greatly reduces the inconvenience and pain caused by surgery to patients. [0003] With the development of modern technology, abdominal surgery has successfully shifted from traditional surgical laparotomy to minimal...

Problems solved by technology

During the operation, the doctor needs to clamp the blood vessels next to the tissue for a long time with ordinary hemostats. When the blood supply is blocked, it is easy to cause fatigue and pain in the fingers, palms, wrist joints and shoulders of the doctor.

Moreover, for multiple bleeding points, multiple traditional hemostats need to be used, which greatly occupies a limited incision space, which is very unfavorable for surgical operations and reducing patient injuries
