Abstract
This utility model relates to a kind of medical apparatus and instruments, especially a kind of operation high-frequency electrical lasso device.High-frequency electrical snare is used in a kind of operation, comprise lasso, drag-line, protecting pipe, slip ring, electrode and core bar, slip ring be provided with spring connect draw pin, draw pin vertically to stretch in core bar outer surface, the upper surface of core bar has scale, core bar is also processed with some detents drawing pin for clamping.The beneficial effects of the utility model are: the distance that lasso can be released according to slip ring reaches different width dimensions, thus can tackle calmly the pathological tissues of different size, improves the efficiency of operation.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of operation high-frequency electrical lasso device.
Background technology
Snare coordinates high-frequency electrical to the excision of various polyp and excess tissue under being mainly used in scope.The size of conventional snare lasso fixes, and the size of pathological tissues will be slightly less than the size of lasso, and such surgical effect is optimal.In fact, many times some patients can miss golden hour, cause pathological tissues to become much larger, once cut when not becoming, need to carry out at least 2 times, but when using snare for the 2nd time, the size of lasso just seems too large, will certainly affect surgical effect.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, a kind of operation high-frequency electrical lasso device is provided, the distance that lasso can be released according to slip ring reaches different width dimensions, thus can tackle calmly the pathological tissues of different size, improves the efficiency of operation.
This utility model solves the technical scheme that its technical problem adopts: a kind of operation high-frequency electrical snare, comprise lasso, drag-line, protecting pipe, slip ring, electrode and core bar, the connecting portion of drag-line and lasso is set with pipe sheath, one end of drag-line is fixedly connected with the tail end of lasso by pipe sheath, the other end is fixedly connected with the head end of protecting pipe, slip ring sleeve is contained on core bar and also can relatively moves axially by core bar, protecting pipe is inserted in core bar, the tail end of protecting pipe and electrode are fixedly connected on core bar, and the tail end of protecting pipe and electrode are electrically connected, described slip ring be provided with spring connect draw pin, the described pin that draws vertically stretches in core bar outer surface, the upper surface of described core bar has scale, core bar is also processed with some detents drawing pin for clamping.
Further, described protecting pipe is tightly locked on core bar by turncap.
Further, described detent is processed with three.Draw through clinical practice, the lasso of three different width dimensions can realize the excision of different size pathological tissues substantially.
The beneficial effects of the utility model are: the distance that lasso can be released according to slip ring reaches different width dimensions, thus can tackle calmly the pathological tissues of different size, improves the efficiency of operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of Fig. 1 ferrule portion.
In figure: 1. lasso, 2. pipe sheath, 3. drag-line, 4. protecting pipe, 5. turncap, 6. electrode, 7. slip ring, 8. core bar, 9. draw pin, 10. scale, 11. detents.
Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
As shown in Fig. 1 ~ Fig. 2, high-frequency electrical snare is used in a kind of operation, comprise lasso 1, drag-line 3, protecting pipe 4, slip ring 7, electrode 6 and core bar 8, drag-line 3 and the connecting portion of lasso 1 are set with pipe sheath 2, one end of drag-line 3 is fixedly connected with by the tail end of pipe sheath 2 with lasso 1, the other end is fixedly connected with the head end of protecting pipe 4, slip ring 7 is sleeved on core bar 8 and also can relatively moves axially by core bar 8, protecting pipe 4 is inserted in core bar 8, the tail end of protecting pipe 4 and electrode 6 are fixedly connected on core bar 8, and the tail end of protecting pipe 4 and electrode 6 are electrically connected, slip ring 7 be provided with spring connect draw pin 9, pin 9 is drawn vertically to stretch in core bar 8 outer surface, the upper surface of core bar 8 has scale 10, core bar 8 is also processed with three are drawn pin 9 detent 11 for clamping.
As shown in Fig. 1 ~ Fig. 2, protecting pipe 4 is tightly locked on core bar 8 by turncap 5.
Under the direct-view of endoscope, find pathological tissues, insert this utility model, while extroversion hauls pin 9, driven forward slip ring 7 opens lasso 1, selects to draw pin 9 to be connected in which detent 11 according to the size of pathological tissues, namely selects the lasso 1 being applicable to size, then tissue is entangled, pull back slip ring 7 to tighten up lasso 1 tissue is tightened up, connect high-frequency electrical cauterize tissue by electrode 7, play the effect of perfect cutting tissue.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
