Abstract
The invention relates to a medical instrument, in particular to a medical snare. The medical snare comprises a loop, a stay rope, a protective sleeve, a sliding ring, an electrode and a core bar, wherein the protective sleeve is firmly locked on the core bar by virtue of a rotary cap; a guide head is arranged at the head end of the loop; the guide head is integrally molded with the loop; the guide head is of a D-shaped structure; an anti-sliding structure is arranged outside the loop; and the anti-sliding structure is formed by distributing a plurality of insulating coils. Since the anti-sliding structure is arranged outside the loop and the anti-sliding structure is formed by distributing the plurality of insulating coils, the snare disclosed by the invention is integrally rough, so that an anti-sliding effect is achieved and the medical snare is easier to hold a tissue for cutting.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, especially a kind of medical snare.
Background technology
Snare coordinates high-frequency electrical to the excision of various polyp and excess tissue under being mainly used in scope.When conventional snare operates, the process that lasso entangles pathological tissues there will be the situation organizing slippage, needs to carry out repeatedly lasso, and the operating time is long, affects surgical effect.Urgent clinical needs want a kind of safe and efficient and anti-skidding medical snare to substitute the snare of existing routine.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of medical snare, its safety easy to use, and can avoid when entangling pathological tissues organizing slippage.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of medical 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 protecting pipe is tightly locked on core bar by turncap, the head end of described lasso has guide head, described guide head and lasso one-body molded, the structure of guide head is alphabetical D type, anti-skid structure is provided with outside described lasso, described anti-skid structure is arranged by multiple insulated coil and forms.
Further, the spacing distance between two insulated coils is 2 ~ 3mm.
The invention has the beneficial effects as follows: be provided with anti-skid structure outside the present invention is trapped, the multiple insulated coil arrangement of anti-skid structure forms, and makes snare entirety become coarse, reaches anti-slip effect, more easily entangle tissue cutting.
Accompanying drawing explanation
Below in conjunction with accompanying drawing embodiment, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the enlarged drawing of Fig. 1 ferrule portion.
In figure: 1. anti-skid structure, 2. lasso, 3. pipe sheath, 4. drag-line, 5. protecting pipe, 6. turncap, 7. electrode, 8. slip ring, 9. core bar, 11. covered wires, 21. guide heads.
Detailed description of the invention
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to the present invention instead of limitation of the invention further are described.
As shown in Fig. 1 ~ 2, a kind of medical snare, comprise lasso 2, drag-line 4, protecting pipe 5, slip ring 8, electrode 7 and core bar 9, drag-line 4) with the connecting portion of lasso 2 on be set with pipe sheath 3, one end of drag-line 4 is fixedly connected with by the tail end of pipe sheath 3 with lasso 2, the other end is fixedly connected with the head end of protecting pipe 5, slip ring 8 is sleeved on core bar 9 and also can relatively moves axially by core bar 9, protecting pipe 5 is inserted in core bar 9, the tail end of protecting pipe 5 and electrode 7 are fixedly connected on core bar 9, and the tail end of protecting pipe 5 and electrode 7 are electrically connected, protecting pipe 5 is tightly locked on core bar 9 by turncap 6, the head end of lasso 2 has guide head 21, guide head 21 is one-body molded with lasso 2, the structure of guide head 21 is alphabetical D type, anti-skid structure 1 is provided with outside lasso 2, anti-skid structure 1 is arranged in order by multiple insulated coil 11 and forms.
Spacing distance between two insulated coils 11 is 2 ~ 3mm.If the spacing distance between two insulated coils 11 is less than 2mm, arranges too close, then can affect cutting effect; If be greater than 3mm, then skidproof effect can be affected.
Under the direct-view of endoscope, find pathological tissues, insert the present invention, by the guide-localization of guide head 21 to tissue, driven forward slip ring 8 is opened lasso 2 and is entangled tissue, pull back slip ring 8 to tighten up lasso 2 tissue is tightened up, connect high-frequency electrical cauterize tissue by electrode 7, play the effect cut and organized.Owing to being provided with anti-skid structure 1 outside lasso 2, organizing not easily slippage when cutting and organizing like this, can not cutting effect be affected.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, must determine its technical scope according to right.
