Description
Technical Field
The utility model belongs to the field of medical equipment, particularly, relate to a laser mucosa cutting tool bit for alimentary canal mucosa cutting.
Background
Endoscopic Submucosal Dissection (ESD) refers to an endoscopic minimally invasive technique for submucosal dissection of lesions > 2cm using various mucosal cutting tools. The technique can realize the whole excision of larger lesions and provide accurate pathological diagnosis staging. With the continuous development of endoscopic instruments, ESD has become the first choice for the treatment of early cancers and precancerous lesions of the digestive tract. In 2006, the clinical application of ESD in China began to be gradually popularized. Due to the great difficulty of the ESD technology, the development levels in various places are uneven.
Most mucosa cutting tool are high frequency electric surgical instruments at present, cause unexpected injury to patient's alimentary canal mucosa easily, and hemostatic effect is unsatisfactory, and the operation degree of difficulty is big, consequently needs one kind to make things convenient for medical personnel to operate, and the cutting tool that the operation risk is lower. The laser surgical instrument is considered to be an upgrading product of the high-frequency surgical instrument due to the excellent performances of high cutting efficiency, good hemostasis effect and the like. However, the existing laser surgical instrument is not suitable for the special requirements of the ESD operation, so that the shape and the structure of the cutter head of the laser surgical instrument need to be specially designed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem, consequently, provide a laser mucosa cutting tool bit for alimentary canal mucosa cutting.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
comprises a cylindrical cutter bar and a core rod extending out of the top end of the cutter bar; the top end of the core rod is connected with the bottom end of the boss; the boss comprises a boss cylinder positioned at the bottom and a spherical convex surface positioned at the top; the boss is made of quartz.
Further, the divergence angle of the laser emitted by the core rod after passing through the boss is 260-280 degrees.
Further, the maximum bending angle of the core rod is 150-160 degrees.
Further, the diameter of the cutter rod is 0.9-1.8 mm.
Further, the diameter of the core rod is 0.3-0.9 mm.
Further, the diameter of the boss is 0.9-1.8 mm.
Further, the length of the core rod is 0-1.6 mm.
Further, the height of the boss cylinder of the boss is 0.2-0.4 mm.
Compared with the prior art, the utility model discloses following beneficial effect has:
(1) the boss of the utility model is made of quartz, and the alimentary canal mucous membrane is cut by laser energy, thereby further avoiding accidental injury to the alimentary canal mucous membrane of a patient in the operation, having good hemostatic effect, high safety factor and higher cutting efficiency;
(2) the utility model discloses a flexible maximum angle of core bar is 150-160, and the pliability is good, can cut the different positions of disease alimentary canal in a flexible way, and the medical personnel of being convenient for operate, and can not obstruct the observation of endoscope.
