Microsurgery instrument with telescopic wedge type pedals

Abstract

The invention relates to a medical instrument used for microsurgery. The microsurgery instrument is composed of a handle outer sleeve convenient to hold with the hand, an inner sleeve with a wedge type pedal locking structure and different microsurgery instrument bodies; a thin-walled medical grade stainless steel tube is sleeved with a high-temperature-resistant nontoxic heat shrinking tube to manufacture the outer sleeve; the inner sleeve is manufactured by a thin-walled medical grade stainless steel tube, the tube wall at the front end of the inner sleeve is manufactured into 2-4 wedge typepedals, and an adjusting nut is arranged at the rear end of the inner sleeve. In the using process, a connecting rod of the needed microsurgery instrument body is inserted into the suitable depth from the front end of the outer sleeve, and the front end of the inner sleeve is inserted from the rear end of the outer sleeve, so that the wedge type pedals are inserted into the narrow gap between therear cylindrical end of the corresponding microsurgery instrument body and the inner side wall of the outer sleeve and fixedly locked. The microsurgery instrument is simple and elaborative in handlestructure and convenient to use and disassemble, the length of the medical instrument bodies can be adjusted freely so that the sharp ends can be inserted into the outer sleeve, the medical instrumentbodies are protected, and medical workers are prevented from being injured accidentally.

Description

technical field [0001] The invention belongs to a microsurgical instrument. Background technique [0002] Microsurgery is a major advance in modern medicine, and various advanced microsurgical instruments provide guarantees for accurate and successful operations. However, with the continuous advancement of microsurgical technology, the requirements for microsurgical instruments are also getting higher and higher. Taking micro-neurosurgery and micro-ear surgery as examples, the corresponding surgical instruments must be very fine and dexterous, easy to operate, and flexible. At present, most manufacturers can do the first two items, but the process and materials are different. However, most manufacturers fail to achieve flexible expansion and contraction. Microneurosurgery and micro ear surgery are similar in most micro instruments, such as various micro hooks, knives, needles, shovels, curettes and strippers. However, due to the different depths of the surgical site, mic...
