Abstract
The utility model provides an adjusting device of an endoscopic sheath instrument. The adjusting device comprises a lifting device, a steel wire channel and a control rotary knob, wherein the lifting device is located at the head of an endoscopic sheath, the steel wire channel is located in a sheath pipe, and the control rotary knob is located at a control part of an endoscope and comprises a gear and a rack. The gear is driven to rotate by rotating the rotary knob, the gear drives the rack and simultaneously drives a steel wire fixed on the rack, the steel wire is connected with the lifting device through the steel wire channel and drives the lifting device to swing at a certain angle, and the angle of a surgical instrument of an instrument channel can be adjusted. The adjusting device of the endoscopic sheath instrument has the advantages that the angle of the surgical instrument is fast and convenient to adjust, and the surgical instrument can swing to reach a required position for surgical operations.
Description
Technical field
This utility model belongs to endoscope's sheath field, especially relates to a kind of endoscope sheath apparatus adjusting device.
Background technology
Conventional cystoscope operating theater instruments and its material of hysteroscope operation apparatus be take rustless steel as main, and the operating theater instruments of stainless steel belongs to open apparatus, apparatus in use cannot endoscope forms sealing completely, and in operation process, endoscope carries out work by being inserted in the apparatus of sheath class.The body fluid producing in human body and operation process can pollute by endoscope, and postoperative endoscope must carry out disinfection.At present occurred that on the market a kind of endoscope carries out endoscope's sheath of totally-enclosed protection.Inside, sheath outside in endoscope.Because endoscope does not contact with anyone, what directly contact human body is disposible.Human body can not form pollution by endoscope yet simultaneously, reduces cross infection.So just can be so that endoscope, without sterilization, can form protective effect by endoscope.At utmost extend the service life of endoscope, disposible cost is lower than common sheath simultaneously, more easily by market, is accepted.
Along with the interior progress of peeping medical procedure, in endoscope detecting, can also directly perform the operation at present, this just requires to be provided with instrument channel in endoscope's sheath.The apparatus that is mainly used at present endoscopic surgery comprises the instrument of different pliers, shears and so on, when apparatus inserts after human body by instrument channel, difference along with lesions position, the apparatus inserting need to have certain angle swinging toward contact, sometimes also will add that certain rotation could adapt to more operation demand.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of endoscope sheath apparatus adjusting device, is especially applicable to regulating the operating theater instruments angle in endoscope's sheath instrument channel, to adapt to more operation demand.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Invent a kind of endoscope sheath apparatus adjusting device, comprise be positioned at endoscope's sheath sheath head lift device, be positioned at sheath pipe steel wire passage, be positioned at the control handle of endoscope's control section; Control handle comprises gear and tooth bar; Wheel and rack engagement; Steel wire one end is fixed on tooth bar, the other end by steel wire passage with lift device and be connected.
Described gear and tooth bar material are medical plastic.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, inside peep in operation apparatus angular adjustment convenient; Have simple in structurely, easy to maintenance, processing cost is low, production efficiency advantages of higher.
