Abstract

The utility model relates to a rotatable gasification resectoscope, which is composed of an endoscope, an inner endoscope sheath, an outer endoscope sheath, an obturator foramen device, an electric cutting device and an electric cutting ring, wherein, the end of the inner endoscope sheath is provided with an endotheca body with a lock slot; the outer side of an endotheca tube above the endotheca body is provided with a liner which is movably connected with the endotheca tube; a lock cap which locks the outer endoscope sheath and the liner is arranged outside the liner; the handle part of the obturator foramen device is provided with male pins which display the raising direction of a closing head of the obturator foramen device. The utility model, which is convenient for the electric cutting device to be locked in one of the endoscope sheathes, can indicate the raising direction of the closing head of the movable obturator foramen device, which facilitates operation.

Description

Rotatable vaporization resectoscope

This utility model relates to a kind of vaporization resectoscope.

Prostate hyperplasia, hypertrophy be in, the high common disease of elderly men sickness rate, endometriosis, uterine cavity foreign body, mucosa infection are also more general in the adult female, except that open excision or Drug therapy, adopt advantages such as the operation of vaporization resectoscope is easy and simple to handle because of it, expense is lower, effect is obvious, clinical practice more and more widely.At present the resectoscope that uses is formed by following five parts: the hard tube endoscope of ° viewing directional angle a.30, b. mirror sheath and movable obturator, c. TURP device, the TURP ring of many kinds of models of d., e. high frequency electric knife.There is following defective in they: when the TURP device is locked at the mirror sheath, can rotate with the mirror sheath, be not easy to locking; Scope sheath and epi mirror sheath can not relatively rotate; Movable obturator closes head and upwarps direction and can't determine.

The purpose of this utility model provides a kind of rotatable vaporization resectoscope that overcomes above-mentioned shortcoming.

For achieving the above object, this utility model is by the following technical solutions: it is made up of endoscope, scope sheath, epi mirror sheath and obturator, TURP device and TURP ring, the scope sheath is provided with the interior sheath body of groove with lock in its termination, the outside of the interior sheath pipe above interior sheath body is provided with the lining that flexibly connects with it, lining is provided with the lock nut of locking epi mirror sheath and lining outward, and the shank of obturator is provided with and shows that obturator closes the pin that head upwarps direction.

This utility model also can adopt following further technical scheme simultaneously:

Sheath and the socket of TURP device conical surface seal in described.

It also is provided with TURP and checks bridge.

The elastic device that TURP device handle connects is a torsion spring.

Owing to adopted technique scheme, behind the lock nut Locking bushing, the sheath body can screw the TURP device in gripping, and the epi mirror sheath can not rotate with the TURP device, also owing to be provided with lining, scope sheath and epi mirror sheath can relatively rotate, and are convenient to excise the different hyperplastic tissue in position, and the pin of the shank of obturator can show that obturator closes head and upwarps direction; Interior sheath and the socket of TURP device conical surface seal can be guaranteed water-tight; TURP is set checks bridge, utilize TURP inspection bridge under endoscope's direct-view, to do the state of an illness inspection when urethra is had any problem than being easier to insert when inserting; The elastic device that TURP device handle connects adopts torsion spring, has adjusted strength, is convenient to the general of active and passive type again.

The utility model is described in further detail below in conjunction with the enforcement of accompanying drawing:

Fig. 1 is the structural representation that inside and outside sheath of resectoscope and movable obturator connect together.

Fig. 2 is a passive type TURP device structural representation.

Fig. 3 is that TURP is checked the bridge construction sketch map.

Fig. 4 is 30 ° of viewing directional angle endoscope sketch maps.

Figure 10 is the sketch map that electricity coagulates ring ring head.

With reference to accompanying drawing 1,4.This utility model is by endoscope 26, the scope sheath, epi mirror sheath and obturator, TURP device and TURP ring 32 are formed, the epi mirror sheath is made up of epitheca pipe 13 and epitheca body 14, the scope sheath is made up of interior sheath pipe 11 and interior sheath body 18, interior sheath pipe 11 is inserted in the epitheca pipe 13, epitheca pipe 13 is provided with inlet opening 12, epitheca body 14 is provided with outlet valve 23 and water intaking valve 15, water intaking valve 15 links to each other with interior sheath pipe 11, outlet valve 23 links to each other with inlet opening 12, the outside of the interior sheath pipe above interior sheath body is provided with the lining 17 that flexibly connects with it, lining is provided with the lock nut 16 of locking epi mirror sheath and lining outward, and scope sheath and lining 17 are free to rotate, and interior sheath body 18 also is provided with locked groove 22.

Obturator comprises and closes 25, handle 20, the sheath lock 19 that cooperates with locked groove 22, is connected and closes 125 with the handle bar 24 of handle 20, be located at shank demonstration obturator and close 15 pins 21 that upwarp direction.

As shown in Figure 2, the TURP device comprise be responsible for 1, the conical surface sheath lock 2 that cooperates with locked groove 22, insulator 4, the mirror that is actively set on the person in charge 1 lock 5, endoscope 26 inserts in the TURP device and by mirror lock 5 and locks the back object observings, front hand grip 9 is fixed on the sheath head 10, back handle 8 is connected with insulator 4, front hand grip 9 also is connected by torsion spring 3 elasticity with back handle 8, and insulator 4 is provided with the tight device 6 of TURP ring lock, high-frequency electrical input hole 7.

As shown in Figure 5, above-mentioned epi mirror sheath also can not established epitheca pipe 13, is used under the situation that need not flushing continuously and makes TURP.

This utility model also can be provided with TURP and check bridge, as shown in Figure 3.TURP checks that bridge comprises sheath pipe 29, and the top of sheath pipe 29 is provided with closes 31, closes 29 center and is provided with the through hole 30 that communicates with sheath pipe 29, and TURP checks that bridge also is provided with sheath lock 28 and mirror lock 327.
