Description

Novel area is washed and is attracted and electricity congeals chamber mirror separating forceps of hemostasis function

Technical Field

The utility model relates to the field of medical equipment, concretely relates to novel chamber mirror separation pincers of suction and electricity congeals hemostasis function are washed in area.

Background

With the continuous development of the operation mode, the endoscope minimally invasive surgery gradually replaces a part of open operation modes due to the advantages of small trauma, quick recovery of patients, wide application range of the operation and the like, and is popular with hospitals and patients. In the endoscopic minimally invasive surgery, a plurality of endoscopic surgical instruments such as a monopolar ablation electrode, a plasma electric knife or an ultrasonic knife are used for cutting, separating or stopping bleeding of target tissues, and auxiliary instruments such as a separating clamp, a grasping clamp, a suction apparatus or a bipolar coagulation clamp are also used.

However, the existing laparoscopic instruments still have more defects:

firstly, the function of the operation instrument is too single, and the operation instrument can not deal with various emergency situations, for example, when tissue cutting separation is carried out through a main knife hole, an auxiliary knife hole channel needs to be arranged on the side edge to assist the operation of a separation forceps, a grasping forceps, a suction apparatus or a bipolar coagulation forceps, but the function of the current endoscope operation instrument used clinically is single, and the instrument needs to be replaced frequently in the operation process. For example, in the process of performing operations such as partial nephrectomy or cleaning of a paravascular lymph node, bleeding and bleeding of tissues and organs are easily caused, and at the moment, a suction irrigator needs to be replaced to perform blood suction and irrigation, so that a blood spot is found out; after the bleeding point is determined (namely after blood suction and flushing), the electrocoagulation separation forceps need to be replaced again for electrocoagulation hemostasis;

secondly, when a target tissue is cut and separated or stopped bleeding by using a single-pole ablation electrode, a plasma electric knife or an ultrasonic knife, a large amount of operation smoke is often generated, smoke is generally exhausted through an operation Trocar hole or an aspirator, the smoke generated in the process of electric cutting and electric coagulation cannot be treated by common separating forceps or grasping forceps, the operation visual field is seriously influenced by the smoke, and the operation efficiency is greatly reduced.

In summary, when a minimally invasive surgery, such as a renal cancer resection, a liver cancer resection, a pancreaticoduodenectomy, or a thoracic surgery, which is prone to bleeding and bleeding, is performed, separating forceps, grasping forceps, a flusher, or a suction apparatus having too single functions cannot meet the surgical requirements, and the surgical safety cannot be guaranteed. Therefore, the endoscope electric coagulation hemostatic separation forceps with the flushing and suction functions, which can clamp tissues, can be externally connected with an electric coagulation function, can flush and discharge smoke, and has the advantages of strong operation functionality, high safety factor and wide operation application range, is urgently needed to be designed.

The novel endoscope separating forceps with flushing suction and electrocoagulation hemostasis functions as claimed in claim 1, is characterized in that: the cutter bar (17) is of a hollow structure, a pull rod channel (14) and a flushing channel (16) are arranged in the cutter bar (17), and the connecting parts of the flushing channel (16) in the cutter bar (17) and the holding handle (26) are all of a closed structure.

9. The novel endoscope separating forceps with flushing suction and electrocoagulation hemostasis functions as claimed in claim 8, wherein: tooth-shaped convex structures are arranged on the clamping surface of the upper tool bit (11) and the clamping surface of the flushing channel (16); the two parts except the inner side tooth-shaped surface are coated with insulating protective paint.

10. The novel endoscope separating forceps with flushing suction and electrocoagulation hemostasis functions as claimed in claim 9, wherein: the pull rod (15) is protected by insulating materials except for the contact part of the electrode contact (221) and the pull rod shaft (13).
