Description

A kind of soft or hard bluk recombination scope

Technical field

The utility model belongs to the field of medical instrument technology, specific for a kind of soft or hard bluk recombination scope.

Background technique

Scope has concentrated traditional optical, ergonomics, precision machinery, hyundai electronics, mathematics, software etc. in one Detecting instrument usually has imaging sensor, optical lens, light source illumination, mechanical device etc., it can be through natural hole or warp The small notch done of performing the operation enters in human body.The position difference reached by scope is classified, and endoscope for ENT, oral cavity can be divided into Scope, dentistry scope, neural mirror, urethrocystoscope, resectoscope, laparoscope, arthroscope, nasal sinus mirror, laryngoscope etc..

Existing scope has hard mirror and two kinds of soft lens.Hard mirror is generally possible to preferably enter into the human body, but hard tube can increase Add the sense of discomfort of patient, or even cause patient muscle's spasm, to hold conduit tightly, is allowed to can smoothly enter into；The intubation of soft lens It can be effectively improved the experience of patient, but relatively difficult when entering human body, it is complicated for operation, the operating experience of medical worker is wanted Ask higher.In order to overcome deficiency existing for existing hard mirror and soft lens, occurs the scope that soft or hard matter combines on the market.

It is peeped as the Chinese patent of Publication No. CN201782744U discloses in a kind of soft or hard matter combined type bendable steering Mirror, it includes conduit portion, the steering tiller and pipe jointer for controlling guiding-tube bend, and the conduit portion includes hard tube and soft Pipe, hard tube cover outside hose, and the steering tiller includes taper knob, shank body lid, and the taper knob, shank body lid are cylinder Shape, taper knob cover outside shank body lid, and axial guidance and sliding block, guide rail and sliding block point are equipped between taper knob and shank body lid It is not fixed on taper knob or shank body covers, the hard tube is fixedly linked with taper knob, and the hose passes through the logical of taper knob center Hole is connected with an interface of pipe jointer and is fixed on interface, is equipped in hose and turns to channel and service aisle, turn to It is equipped in channel and turns to steel wire, the outer end of the hose is provided with hard sheath, and positioning is equipped in the steering channel in hose Casing is equipped with elastic tube in the hose between locating sleeve and hard sheath, turns to steel wire and passes through locating sleeve and elastic tube, One end is fixedly connected with hard sheath, and the interface that the other end passes through pipe jointer can control steering steel with what is covered positioned at shank body The flexible steering control valve connection of silk, the pipe jointer is located in shank body lid to be fixedly linked with shank body lid, pipe jointer Each passway for being covered respectively with shank body by respective hose connector of remaining interface connect.

The soft or hard matter combined type bendable steering endoscope, in clinical use, conduit portion enters human body urinary tract, it Hose bending is operated by handle afterwards, complete to check or is treated.The soft or hard matter combined type bendable steering endoscope, although operation letter It is single, it is easy to use, and can have a better effect, but there are still traditional ureteroscope hard intubations the problem of, it may be assumed that it is hard Pipe will increase the sense of discomfort of patient, or even cause patient muscle's spasm, to hold conduit tightly, being allowed to cannot when entering human body It can smoothly enter into urinary catheter.In addition, covering the structure outside hose using hard tube, the diameter of conduit entirety will increase, so that conduit exists When the patient of insertion children's urethra or ureterostenosis, the resistance being subject to is big, it is easier to cause the spasm of patient muscle, or to trouble The urethra of person causes centainly to injure.When in use, the part of flexible pipe extending hard tube is bent under the operation of handle, due to leading Pipe operator when being inserted into urinary catheter can't see internal situation, if the control that the length of flexible pipe extending hard tube is shorter and in handle When lower pressure is bent, it is easy to which the optical fiber to fracture in hose because bending radius is too small causes endoscope to damage.

The Chinese patent of Publication No. CN103393395B discloses a kind of bendable end type urine output of concertina type epitheca Guan Jing, it is made of endoscope and flexible sheath, the endoscope include endoscopic main body and with endoscopic main body successively The rigid section of connection, can curved segment and camera lens；The flexible sheath is cylindrical empty cardiac catheter, is set in the outside of rigid section, stretches One end of contracting sheath is connect with endoscopic main body；The endoscopic main body includes: handle, the control mechanism in handle, on handle Light guide bundles interface, water inlet interface and handle end eyepiece and focus adjustment knob；Including the control mechanism setting In control chamber in the handle of sight glass ontology, the control mechanism includes that the radius of gyration adjusts unit and deflection lens direction tune Save unit；It includes: spill spin block that the deflection lens direction, which adjusts unit, and the spill spin block is movably fixed on exchanger axis, One end of the spill spin block is equipped with adjusting knob；The side of the spill spin block, the exchanger axis is arranged in exchanger axis, the exchanger axis It is bonded with the rigid section；And line is adjusted, the both ends of the spill spin block are arranged in the line that adjusts, described in the adjustings line passes through Intersect after exchanger axis and be bonded and is arranged on the rigid section inner wall.

Be sequentially connected on the endoscopic main body of the Ureter mirror with flexible end of the concertina type epitheca equipped with rigid section, can Curved segment and camera lens are arranged flexible sheath outside rigid section, using position of the flexible sheath on rigid section, make can curved segment expose outside flexible sheath Or make can curved segment retraction stretch it is intrathecal.During entering human body, can curved segment retraction intrathecal, the rigid flexible sheath that stretches equally can Increase the sense of discomfort of patient, or even cause patient muscle's spasm, to hold conduit tightly, is allowed to that urinary catheter cannot be can smoothly enter into.Similarly, Using flexible sheath in the structure outside rigid section, integral diameter will increase, so that in insertion children's urethra or ureterostenosis Patient when, the resistance being subject to is big, it is easier to cause the spasm of patient muscle, or cause centainly to injure to the urethra of patient.

To sum up, the thin urinary catheter mirror that existing soft or hard matter combines is not only without solving to cause asking for patient's sense of discomfort even spasm Topic, and there is also outer diameter increase, the complicated problems of lens direction control.
