Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of endoscope-assistant surgery lymph node biopsy pincers.
Background technology
Along with making rapid progress of surgical operation development, technology also improves and development continuous, and Minimally Invasive Surgery is the main direction of surgical operation development, because the continuous development of thoracoscope and laparoscopic surgery requires also constantly to promote for the apparatus of performing the operation; And the treatment of the Minimally Invasive Surgery of tumor also is the most important developing direction that minimally invasive surgery is learned, and is very high to the requirement of operating theater instruments.
Clinically, excision and the cleaning operation to lymph node is difficult relatively under the mirror of chamber.Lymph node change of shape under external force is unstable; Especially in operation because the external force effect is very easily broken, extruding conforms with broken lymphoid tissue possibly cause tumor cell generation micrometastasis or operating field plantation in the cancer patent lymph node.
It is at present, domestic that also not have a kind of apparatus be to be applied to carry out under thoracoscope or the peritoneoscope apparatus that lymph node biopsy or its hetero-organization carry out biopsy.
The utility model content
The purpose of this utility model provides a kind of endoscope-assistant surgery lymph node biopsy pincers that can conveniently extract or win lymph node.
For realizing above-mentioned purpose; The technical scheme that this utility model adopted is: a kind of endoscope-assistant surgery lymph node biopsy pincers; Comprise moving pincers handle and quiet pincers handle; Said quiet pincers handle is divided into handle portion, claw beam part and jaw part, and said moving pincers handle is made up of handle, moving claw beam and moving jaw, partly is provided with spacing hole at claw beam; Handle and moving claw beam are hinged, and moving claw beam and moving jaw are hinged, and on moving claw beam, are provided with the spacing preiection that matches in spacing hole, and moving claw beam and claw beam partly are interlockingly connected, and moving jaw and jaw partly are hinged; Handle and quiet pincers handle are hinged at handle portion.
Be provided with mutual interlock cutting teeth between said moving jaw and the jaw part.
Be provided with in said moving jaw and the jaw part and collect groove.
Said quiet pincers handle is a bending.
This utility model has the following advantages after adopting said structure:
1, the spacing preiection on the spacing hole of claw beam part and the moving claw beam; Make claw beam that the extreme position move left and right arranged, what make moving jaw dehisces limitedly, promptly is that very little otch all can put in and undergos surgery or win the detection thing; And very convenient, satisfied the requirement of Minimally Invasive Surgery.
2, adopt mutual interlock cutting teeth, it is firm to catch thing, and not hemorrhage.
3, adopt forniciform quiet pincers handle, avoid influencing the observation visual angle of chamber mirror, further facilitated the operation technique person.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further explain:
Fig. 1 is this utility model structure chart;
Fig. 2 is the moving jaw open configuration structure chart of this utility model;
Fig. 3 is the structural representation of moving jaw of this utility model and jaw part;
Fig. 4 is the A-A profile of Fig. 3.
Among the figure: 1 moving pincers handle, 11 handles, 12 moving claw beams, 121 spacing preiections, 13 moving jaws, 2 moving pincers handles, 21 handle portions, 22 claw beam parts, 221 spacing holes, 23 jaw parts, 3 cutting teeths, 4 collect groove.
The specific embodiment
Fig. 1,2, shown in 3 and 4; The endoscope-assistant surgery lymph node biopsy pincers of this utility model; Comprise moving pincers handle 1 and quiet pincers handle 2; Said quiet pincers handle 2 is divided into handle portion 21, claw beam part 22 and jaw part 23, and said moving pincers handle 1 is made up of handle 11, moving claw beam 12 and moving jaw 13, is provided with spacing hole 221 in claw beam part 22; Handle 11 is hinged with moving claw beam 12, and moving claw beam 12 is hinged with moving jaw 13, on moving claw beam 12, is provided with the spacing preiection 121 that matches in spacing hole 221, and moving claw beam 12 is interlockingly connected with claw beam part 22, and moving jaw 13 is hinged with jaw part 23; Handle 11 is hinged at handle portion 21 with quiet pincers handle 2.Between moving jaw 13 and jaw part 23, be provided with the cutting teeth 3 of mutual interlock.In moving jaw 13 and jaw part 23, be provided with and collect groove 4, two and collect groove 4 and formed a sealing and collect the chamber.Said quiet pincers handle 2 is a bending, avoids influencing the observation visual angle of chamber mirror, has further facilitated the operation technique person.
Above-mentioned spacing hole 221 can replace with stopper slot, and its effect is the same.
Operation principle: hold handle 11 and handle portion 21, handle 11 is inwardly pushed, drive moving claw beam 12 and move backward, the moving jaw 13 of pulling simultaneously upwards opens, and cutting teeth 3 alignings need be won thing; Handle 11 to extrapolation, is driven moving claw beam 12 and moves forward, and the moving jaw 13 of pulling simultaneously closes up downwards, has accomplished winning the cutting of thing.Very convenient.
Because the spacing preiection 121 on the spacing hole 221 of claw beam part 22 and the moving claw beam 12; Make claw beam 12 in limited position move left and right; What make moving jaw 13 dehisces also very limitedly, promptly is that very little otch all can put in and undergos surgery or win the detection thing, satisfies the requirement of the Minimally Invasive Surgery of knowing clearly.
The above is the preferred implementation of this utility model; Certainly can not limit the interest field of this utility model with this; Should be understood that; For those skilled in the art, the technical scheme of this utility model is made amendment or is equal to replacement, do not break away from the protection domain of this utility model technical scheme.
