Abstract

A winding prevention type multifunctional high-frequency scalpel of an endoscope comprises a scalpel head (1) and a core pin (5). A rotating handle (8) is arranged at one end of the core pin (5), and one end of the scalpel head (1) is fixedly inserted into the core pin (5). The winding prevention type multifunctional high-frequency scalpel of the endoscope is characterized in that a liquid injection hole (2) is arranged in the scalpel head (1), one end of the liquid injection hole (2) is communicated with a liquid spraying hole at a scalpel tip of the scalpel head (1), the other end of the liquid injection hole (2) is communicated with a liquid injection connecting tube (6), the liquid injection connecting tube (6) extends out of the core pin (5) to be communicated with a liquid source, the core pin (5) is movably inserted in a slider (4) and can be driven to rotate relative to the slider (4) by the rotating handle (8), a conductive plug mounting sleeve (9) capable of rotating relative to the core pin (5) is sleeved at the other end of the core pin (5), a conductive plug (7) is fixed in the conductive plug mounting sleeve (9), one end of the conductive plug (7) contacts with one end of a conductive spring (10) in an abutted manner, the other end of the conductive spring (10) contacts with a conductive ring or conductive steel ball (11) in an abutted manner, and the conductive ring or conductive steel ball (11) slidably contacts with the scalpel head (1). The winding prevention type multifunctional high-frequency scalpel is simple in structure and flexible in operation, andcan reduce complications.

Description

technical field

[0001] The invention relates to a medical device, in particular to a high-frequency incision knife for excision of mucosal tissue under an endoscope, in particular to an anti-winding type multifunctional endoscope high-frequency incision knife. Background technique

[0002] As we all know, endoscopic submucosal dissection (ESD) is a method of mucosal resection for gastrointestinal lesions. ESD surgery is generally first to inject liquid into the submucosal layer of the lesion to bulge the tissue to be resected, then use a high-frequency incision knife and other instruments to cut along the edge of the raised lesion (circle cut), and then repeatedly inject the liquid under the mucosa and along the The submucosa is gradually peeled off the diseased tissue until the lesion is resected.

[0003] At present, clinically, before performing submucosal dissection, it is necessary to use other instruments (special endoscopic injection needles) to inject the mucosa to ...

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Such as Figure 1-7 shown.

[0032] An anti-winding type multifunctional endoscope high-frequency incision knife, including a knife head 1, a core rod 5, a slider 4 and a conductive plug 7, etc., such as figure 1 , 7 As shown, there is a liquid injection hole 2 on the cutter head 1, one end of the liquid injection hole 2 communicates with the liquid spray hole on the tip of the cutter head 1, and the other end directly communicates with the liquid injection connecting pipe 6 Or communicate with the liquid injection connecting pipe 6 through the liquid guide hole on the core rod 5, and the liquid injection connecting pipe 6 communicates with the liquid source (physiological saline). Through Hole L Type ( figure 2 ), pin type with through hole ( image 3 ), Straight type with through hole ( Figure 4 ), polygonal type with through hole (...
