Abstract
The utility model discloses a kidney lithotomy forceps belongs to medical instrument technical field, including claw beam and claw the top fixedly connected with bracing piece of claw beam, claw articulates on the top of bracing piece the circular -arc electric telescopic handle of both sides fixedly connected with of bracing piece, electric telescopic handle's the other end is articulated mutually with claw claw's inboard fixedly connected with a plurality of sucking disc be equipped with negative pressure generating device in the claw beam, negative pressure generating device is connected with the sucking disc through the breather pipe of fold form, the utility model has the advantages of reasonable design simply, convenient operation is getting the in -process of stone, and electric telescopic handle can drive claw and snatch the calculus, and labour saving and time saving, sucking disc can adsorb in the calculus, can prevent the calculus slippage, convenient and practical.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of kidney lithotomy forceps.
Background technology
The treatment that extracorporeal shock-wave lithotomy is urinary system calculus brings revolution, if but renal calculus merging renal function is poor, the situations such as stricture of ureter, still need to open surgery, China's County Hospital is now many based on open surgery, the most frequently used modus operandi of renal calculus is pyelolithotomy, the kidney stone forceps of current Clinical practice its take the plane that stone face is shallow band, by calculus in its gripping kidney, lithotomy forceps contacts little with calculus face, when particularly calculus is positioned at renal pelvis, it is often that calculus tip is exposed in renal pelvis or towards renal pelvis, pyelolithiasis surrounding space is limited, lithotomy forceps binding clip often difficulty crosses calculus diameter maximum, it is only capable of clamping calculus one end, calculus easily slips, sometimes for preventing calculus from slipping, with clamp energetically, a calculus part is caught broken, difficulty is brought to operation.
Summary of the invention
Technical assignment of the present utility model is a kind of kidney lithotomy forceps provided for above the deficiencies in the prior art.
This utility model solves its technical problem and be the technical scheme is that a kind of kidney lithotomy forceps, including claw beam and chela, it is fixedly connected with support bar on the top of described claw beam, described chela is hinged on the top of support bar, the electric expansion bar of arc-shaped it is fixedly connected with in the both sides of described support bar, described electric expansion bar can be selected for the electric expansion bar that model is SNT-01 that Nanjing Yong Nuo drive apparatus company limited produces, the other end of described electric expansion bar and chela are hinged, it is fixedly connected with several suckers in the inboard of described chela, it is provided with depression generator in described claw beam, described depression generator is connected with sucker by the breather of accordion.
The utility model has the advantage of: 1, this utility model reasonable in design is simple, easy to operate；2, this utility model is in the process taking stone, and electric expansion bar can drive chela to capture calculus, time saving and energy saving；3, this utility model is when taking stone, and sucker can be adsorbed in calculus, can prevent calculus from slipping, convenient and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of part A in Fig. 1.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described below.
nullAs depicted in figs. 1 and 2，A kind of kidney lithotomy forceps，Including claw beam 3 and chela 1，It is fixedly connected with support bar 2 on the top of described claw beam 3，Described chela 1 is hinged on the top of support bar 2，The electric expansion bar 6 of arc-shaped it is fixedly connected with in the both sides of described support bar 2，Described electric expansion bar 6 can be selected for the electric expansion bar that model is SNT-01 that Nanjing Yong Nuo drive apparatus company limited produces，The other end of described electric expansion bar 6 and chela 1 are hinged，It is fixedly connected with several suckers 4 in the inboard of described chela 1，It is provided with depression generator 7 in described claw beam 3，Described depression generator 7 is connected with sucker 4 by the breather 5 of accordion，During use，When chela 1 reaches the position of calculus，That opens chela 1 opens switch，Namely the retraction switch of electric expansion bar 6 is opened，Electric expansion bar 6 drives chela 1 to open，Then chela 1 is put into the outside of calculus，Again the Guan Bi of chela 1 is switched and open，Namely the elongation switch of electric expansion bar 6 is opened，Electric expansion bar 6 drives chela 1 to close，After capturing calculus，Then the switch of depression generator 7 is opened again，Sucker 4 can be adsorbed in calculus，Finally calculus is taken out.
