Abstract
The invention discloses a duodenal papilla incision knife. A knife body is shaped like a long and thin strip, can freely penetrate through a biopsy hole of a gastroscope and is provided with a hollow wire penetrating channel, and one steel wire can be inserted into the wire penetrating channel; the front end of the knife body is provided with a section of a knife head, the front section of the steel wire penetrates out of the wire penetrating channel and then is embedded in the knife head, the knife head is supported at the front end of the knife body through the front section of the steel wire, and the steel wire can rotate to drive the knife head to rotate; the tail end of the knife head is provided with a wire pulling guide seat, and the wire pulling guide seat is provided with a wire feeding hole; the knife body is further provided with a thin metal wire in an embedded mode, the front section of the thin metal wire penetrates out of the front end of the knife body and then penetrates into the wire feeding hole, and the head end of the front section of the thin metal wire is embedded into the front end of the knife head. The duodenal papilla incision knife has the advantages of being novel in structure, more flexible in operation, higher in practicability and more ideal in clinical application effect.
Description
Technical field
The invention belongs to area of medical devices, relate to a kind of sphincterotomy cutter.
Background technology
nullThe cutting operation of vater's papilla is applicable to the diseases such as choledocholithiasis must carry out the patient of vater's papilla flesh incision，This Minimally Invasive Surgery difficulty is very big，It needs to insert until the duodenal site of this patient the incision knife head end of elongate strip form through the biopsy duct of the scopes such as duodenoscope，Then the filament being built on incision knife of pulling back on tail end is being cut，The head end shape making incision knife forms crescent cutter head，Vater's papilla flesh can be cut by this crescent cutter head，The operation of the programs such as the biliary tract stone extraction being thus easy to next step，But there is the incision knife head end of elongate strip form in actual clinical practice and enter after in patient's vater's papilla and there will be the problem that direction is not corresponding in this modus operandi，Namely crescent cutter head can not a step put in place with regard to corresponding with vater's papilla bile duct stenosis direction，And the position that the optimum orientation of vater's papilla bile duct stenosis is 10 ~ 12，Doctor is so needed to be adjusted back and forth solving.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of sphincterotomy cutter, the cutter head of its energy flexible sphincterotomy cutter rotates, the cutter head making incision knife can correspond on vater's papilla rapidly, and it has novel structure, it is more flexible to operate, practicality is higher, clinical application effect more preferably feature.
In order to achieve the above object, the present invention takes following concrete technical measures: a kind of sphincterotomy cutter, it is characterised in that
Cutter hub is elongated strip, and cutter hub freely can be walked in the biopsy hole of gastroscope, and what cutter hub was provided with a hollow wears a passage, wears a passage capable of being and inserts a steel wire；
The front end of cutter hub is provided with a parting tool head, and the leading portion of steel wire is imbedded this cutter head after a passage runs through from wearing, and cutter head is supported in the front end of cutter hub by the leading portion of steel wire, the rotation with dynamic cutter head of the rotational of steel wire；
The tail end of cutter head is provided with one and pulls a guide bracket, and this pulls a guide bracket and offers string silk hole；
Cutter hub is also embedding a fine wire, and the leading portion of this fine wire penetrates string silk hole from the front end of cutter hub after running through, in the front end of the leading portion head end embedment cutter head of fine wire；
Rotating rotation with dynamic cutter head by what control steel wire, the leading portion of fine wire rotates with the rotation of cutter head simultaneously, and now the leading portion of fine wire is in relaxed state；
By straining fine wire, fine wire part in embedment cutter hub is pulled back and is pulled drawing-down leading portion wiry simultaneously, and the leading portion of fine wire rapidly enters stringy and tense pulse state, being in the fine wire leading portion of stringy and tense pulse state to control cutter head and make arc-shaped bend, between cutter head and the fine wire of stringy and tense pulse of arc-shaped bend, combination forms crescent cutting knife.
The present invention rotates the rotation with dynamic cutter head by control steel wire, make cutter head can realize quickly location with the position of 10 ~ 12 on vater's papilla, after tension fine wire, combined the crescent cutting knife formed between cutter head and the fine wire of stringy and tense pulse of arc-shaped bend can the position of on vater's papilla 10 ~ 12 be cut, be thus more beneficial for entering the program of lower one biliary tract stone extraction.
The beneficial effects of the present invention is, it has novel structure, it is more flexible to operate, practicality is higher, clinical application effect more preferably feature.
Below in conjunction with drawings and Examples, the present invention is illustrated further.
Accompanying drawing explanation
Local combined connecting structure amplification profile when Fig. 1 is that in the present invention, fine wire is in non-stringy and tense pulse state.
Detailed description of the invention
As it is shown in figure 1, a kind of sphincterotomy cutter, it is characterised in that
Cutter hub 1 is in elongated strip, and cutter hub 1 freely can be walked in the biopsy hole of gastroscope, and what cutter hub 1 was provided with a hollow wears a passage, wears a passage capable of being piece steel wire 4 of insertion；
The front end of cutter hub 1 is provided with a parting tool head 2, and the leading portion of steel wire 4 is imbedded this cutter head 2 from wearing after a passage runs through, cutter head 2 is supported in the front end of cutter hub 1, the rotation with dynamic cutter head 2 of the rotational of steel wire 4 by the leading portion of steel wire 4；
The tail end of cutter head 2 is provided with one and pulls a guide bracket 21, and this pulls a guide bracket 21 and offers string silk hole；
Cutter hub 1 is also embedding a fine wire 3, and the leading portion of this fine wire 3 penetrates string silk hole from the front end of cutter hub 1 after running through, in the front end of the leading portion head end embedment cutter head 2 of fine wire 3；
Rotating rotation with dynamic cutter head 2 by what control steel wire 4, the leading portion of fine wire 3 rotates with the rotation of cutter head 2 simultaneously, and now the leading portion of fine wire 3 is in relaxed state；
By straining fine wire 3, fine wire 3 part in embedment cutter hub 1 is pulled back and is pulled the leading portion drawing and attenuating tinsel 3 simultaneously, and the leading portion of fine wire 3 rapidly enters stringy and tense pulse state, being in fine wire 3 leading portion of stringy and tense pulse state to control cutter head 2 and make arc-shaped bend, between cutter head 2 and the fine wire 3 of stringy and tense pulse of arc-shaped bend, combination forms crescent cutting knife.
