Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a hard externally-matched rotatable auxiliary channel of an endoscope.
Background
With the improvement of medical level and the development of endoscope technology, more and more operations can be performed through an endoscope through a natural orifice of a human body, and the endoscope operation has the advantages of small wound, quick recovery, attractive appearance and the like. However, the operation of the endoscope is still limited, the current endoscope is mostly provided with a single operation channel, complex operation is difficult to realize, and the increase of the operation channel is beneficial to improving the application of equipment and improving the surgical excision effect. Researchers have bundled an auxiliary channel outside the soft gastroscope to improve the performance of Endoendoscopic Mucosal Resection (EMR) surgery. However, the hard endoscope has no related external equipment at present, the application range of the hard endoscope is wide, particularly in the field of urology, various transurethral hard endoscopes are all single operation channels, and the instruments are widely applied to transurethral urinary calculus lithotripsy and stone extraction, transurethral bladder tumor resection, transurethral prostate resection and other operations.
Transurethral cystectomy (TURBT) is the primary surgical treatment for non-muscle invasive bladder cancer. However, with the development of surgical equipment, the application of laser to transurethral cystocele monoblock resection (ERBT) may help to obtain better pathological specimens and to more accurately stage the pathology; reducing the incidence of bladder perforation; may reduce the secondary resection rate, reduce the recurrence rate, and possibly improve the prognosis of the patient. Because of these potential advantages, ERBT is gaining increasing attention. At present, the operation is mainly performed by using a single operation channel bladder endoscope, and is still limited by various aspects such as the position and the size of the tumor, the operation experience of an operator and the like. Therefore, an auxiliary channel is added on the basis of the original endoscope, which is beneficial to improving tumor exposure, improving operation refinement and excision integrity. Transurethral laser lithotripsy is a common treatment operation for treating vesical calculus and ureteral calculus, and because the ureteral cavity is narrow, calculus displacement is less when the ureteral calculus is broken more, but the vesical cavity is large, the mobility of calculus is larger when the calculus is broken, and the calculus displacement in the calculus breaking process can possibly cause the prolongation of operation time and the possibility of accidentally injuring the vesical mucosa by laser. If an auxiliary channel is arranged outside the original endoscope, one operation channel can be placed into an operation clamp to fix the calculus, and the other operation channel is placed into the laser optical fiber to break the calculus, so that the stone breaking efficiency and accuracy can be improved.
Rigid endoscopes are also widely used for many other disease diagnoses and treatments, and a single operating channel makes their use somewhat limited. In the prior art, a rigid endoscope with two operating channels is also available, but because two operating channels are usually fixedly arranged, for example, the inventor discloses a prior patent application with CN112674869A, the following technical problems can be caused in practical use: firstly, after the operation forceps are arranged in one operation channel to fix tissues, if the position of the operation channel cannot be changed, the other operation channel can only carry out cutting operation in the range of the fixed point, and the operation efficiency is low; secondly, in addition to the sharp separation operation such as cutting, the focal resection operation can separate the tissue by tension along the tissue boundary (blunt separation), and since the relative positions of the two fixed channels are constant, the tissues operated by the instruments in the two operation channels are fixed relative to each other, and the tension cannot be changed, so that the blunt separation is difficult to achieve.
