Description

Trachea retractor for minimally invasive thoracic surgery

Technical Field

The utility model relates to the field of medical equipment, concretely relates to trachea drag hook for minimally invasive thoracic surgery.

Background

In minimally invasive endoscopic surgery, trachea tissues mutually adhered in a human body cavity need to be grabbed and separated, and the electric coagulation hemostasis requirement is met in the grabbing process so as to facilitate smooth operation. The electrocoagulation pliers in the prior art only have the function of clamping or propping open the trachea, do not have the function of hooking and pulling, need to carry out hooking and pulling operation trouble through the electrocoagulation hook, and the electrocoagulation pliers prop open the trachea by an excessively small amplitude, resulting in a small visual field observed by a doctor. Therefore, the utility model provides a trachea retractor for minimally invasive thoracic surgery.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the electrocoagulation pliers among the prior art and only pressing from both sides tight or strut tracheal function, do not have the hook and draw the function, and electrocoagulation pliers struts tracheal angle undersize, leads to the less problem in the field of vision that the doctor observed.

In order to achieve the purpose, the utility model provides a tracheal retractor for minimally invasive thoracic surgery, which comprises an electric coagulation forceps body, wherein the electric coagulation forceps body comprises a sleeve pipe assembly and a handle assembly connected to one end of the sleeve pipe assembly; it is characterized by also comprising a hook binding clip component arranged at the other end of the casing component; the draw hook binding clip subassembly includes the pincers of installing on the thimble assembly, installs the pincers seat on the pincers and sets up the draw hook that is used for moving the trachea on the pincers.

Further preferably, the tail end of the clamp is provided with a connecting plate connected with the sleeve assembly; and nondestructive teeth are arranged on the contact surfaces of the forceps holder and the forceps holder.

Preferably, the sleeve assembly comprises a sleeve and a pull rod, wherein the pull rod is arranged on the forceps base, one end of the pull rod is movably connected with the connecting plate through a connecting pin, and the other end of the pull rod is connected with the handle assembly.

Further preferably, the handle assembly comprises a fixed handle, a movable handle movably mounted on the fixed handle and connected with the pull rod, and an electrocoagulation head mounted on the fixed handle and connected with the pull rod; the fixed handle is movably provided with a tong head rotary handle connected with the pull rod.

The utility model has the advantages that: by means of the draw hook, the function of hooking and pulling the trachea is added while the clamping function of the forceps jaws on the trachea tissue is kept, so that when the trachea needs to be hooked and pulled in the process of surgery, the cooperation of an electric coagulation hook is not needed, the draw hook can be directly used for hooking and pulling the trachea, and further the surgery operation is simpler;

when the trachea tissue needs to be stretched for observation, the end face of the drag hook can be contacted with the trachea tissue for stretching, the stretching amplitude of the trachea can be increased, and the visual field of a doctor is wider.
