Problems solved by technology

Its shortcomings such as Figure 5 The shown stainless steel outer tube (5) and stainless steel middle tube (3) are equipped with lighting optical fiber. When epoxy glue is cured, the epoxy glue expands, so that the sapphire window plate fixing seat (2) and the stainless steel middle tube (3) The welds between the tubes are squeezed by external force, which leads to the weld opening, and the air leakage probability of the rigid tube endoscope increases
[0009] The technical problem to be solved in this patent is: the domestic hard tube endoscope is easy to leak air and water, and cannot be sterilized by high temperature

Abstract

According to the high-temperature-resistant hard-tube endoscope, the sapphire diaphragm and the sapphire diaphragm fixing base are sealed in a braze welding mode, then a welding piece is welded to the inner hole wall of the stainless steel middle tube in a laser sealing mode, and the hard-tube endoscope produced through the technology can resist 134 DEG C high-temperature sterilization more than 2000 times.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, and in particular relates to a high temperature-resistant hard tube endoscope. The hard tube endoscope produced by adopting the technology can satisfy the high temperature sterilization for more than 2000 times. Background technique [0002] In today's world, minimally invasive surgery has become the development direction of various fields of surgical medicine. Minimally invasive surgery is more and more widely used due to its advantages of less damage to patients, less pain for patients during surgery, and shorter postoperative recovery time. The development of any minimally invasive surgery is inseparable from the rigid endoscope. Rigid tube endoscope is welcomed by patients and surgeons for its advanced technology, convenient application, product diversification and specialization. At present, cystoscopy, hysteroscopy, laryngoscopy, sinusoscopy, laparoscopy, arthroscopy, etc. have ...
