Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically a kind of snare.
Background technology
Snare is a kind of conventional medical apparatus and instruments, is mainly used in the ligation of the ligation of the tract organs such as vermiform appendix is residual, gallbladder is residual, fallopian tube and rectum, sigmoid colon polyp.The snare of prior art comprises sleeve pipe and is placed in the snare draught line in sleeve pipe, one end of snare draught line is formed by knots tied a telescopic snare, snare is placed in outside sleeve pipe, and the other end of snare draught line is fixedly connected with the end of sleeve pipe, on sleeve pipe, away from one end of snare, is provided with and interrupts district.During use, fracture and interrupt district, snare is enclosed within focus, and firmly tension interrupts district, and snare is locked in focus, finally with scalpel, cut off snare draught line.But because snare draught line part to be cut is more tiny, and be again at patient's in-vivo procedures, so cut off this step more complicated of snare draught line with scalpel, need to consume many time, and when operation need very carefully, careless slightlyly will cause secondary injury to patient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of novel structure is provided, easy to operate snare.
To achieve these goals, the technical solution of the utility model is as follows: a kind of snare, comprise sleeve pipe and be placed in the snare draught line in sleeve pipe, one end of snare draught line is formed by knots tied a telescopic snare, snare is placed in outside sleeve pipe, the other end of snare draught line is fixedly connected with the end of sleeve pipe, on sleeve pipe, away from one end of snare, be provided with and interrupt district, described sleeve pipe is provided with cutting assembly near the inside, one end of snare, cutting assembly comprises an installing plate, two bar blades, one guide ring and a blade draught line, installing plate and guide ring are respectively on the relative inwall that is fixed on sleeve pipe, one end of two bar blades is overlapped and be hinged on installing plate, the other end launches to form respectively one " people " character form structure to both sides, the blade of two bar blades is oppositely arranged, stretch out outside sleeve pipe one end of blade draught line, the other end is divided into two Y-tracks through after guide ring, two Y-tracks are tied up respectively on the expansion end of two bar blades, snare draught line is arranged between two bar blades.
Adopt after technique scheme, this utility model compared with prior art, have the following advantages: this utility model snare novel structure, when being locked, snare only need draw the blade draught line that is placed in jacket exterior just can cut off smoothly snare draught line after focus, easy to operate, saved with scalpel and cut off this complex steps of snare draught line, saved operating time, alleviated sufferer painful, also avoided patient to cause secondary injury simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the external structure schematic diagram of this practical snare.
Accompanying drawing 2 is top views of the internal structure of this practical snare.
Shown in figure: 1, sleeve pipe 2, snare draught line 3, snare 4, interrupt district 5, installing plate 6, bar blade 7, guide ring 8, blade draught line 9, Y-track.
the specific embodiment
Below by drawings and Examples, this utility model is further elaborated.
As depicted in figs. 1 and 2: a kind of snare, comprises sleeve pipe 1 and be placed in the snare draught line 2 in sleeve pipe 1.One end of snare draught line 2 is formed by knots tied a telescopic snare 3, and snare 3 is placed in outside sleeve pipe 1, and the other end of snare draught line 2 is fixedly connected with the end of sleeve pipe 1, on sleeve pipe 1, away from one end of snare 3, is provided with and interrupts district 4.Sleeve pipe 1 is provided with cutting assembly near the inside, one end of snare 3, and cutting assembly is from sleeve pipe 1 end 0.5-1.0 centimetre.Cutting assembly comprises an installing plate 5, two bar blades 6, a guide ring 7 and a blade draught line 8.Installing plate 5 and guide ring 7 are respectively on the relative inwall that is fixed on sleeve pipe 1, and installing plate 5 is all vertical with the axis of sleeve pipe 1 with guide ring 7.One end of two bar blades 6 is overlapped and be hinged on installing plate 5 by bearing pin, and the other end launches to both sides respectively to form one " people " character form structure, and the opening surface of " people " font is to guide ring 7.The blade of two bar blades 6 is oppositely arranged.It is outer as operating side that sleeve pipe 1 is stretched out in one end of blade draught line 8, while specifically implementing, can on sleeve pipe 1 sidewall, open a duck eye, then by blade draught line 8 from duck eye stretches out sleeve pipe.The other end of blade draught line 8 is tied up respectively on the expansion end of two bar blades 6 through being divided into two Y-track 9, two Y-tracks 9 after guide ring 7.During concrete enforcement, can on the expansion end of two bar blades 6, bind respectively two ropes, then by two ropes from the bottom up through the son of twisting into a rope after guide ring 7, this strand has just formed described blade draught line 8.Snare draught line 2 is arranged between two bar blades 6, that is to say that snare draught line 2 passes between two bar blades 6.During use, only need draw blade draught line 8 operating sides that are positioned at outside sleeve pipe 1, two bar blades 6 just can be take bearing pin as axle center opposite direction rotating under the pulling of two Y-tracks 9, when snare draught line 2 is clamped by two bar blades 6, just can be cut off.
This utility model snare novel structure, when being locked, snare 3 only need draw the blade draught line 8 that is placed in sleeve pipe 1 outside just can cut off smoothly snare draught line 2 after focus, easy to operate, saved with scalpel and cut off snare draught line 2 these complex steps, saved operating time, alleviated sufferer painful, also avoided patient to cause secondary injury simultaneously.
The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content in description, must determine according to claim scope the scope of its protection.
