Abstract
The present invention relates to an improved biological specimen breaker. The breaker adopts a built-in structure that a cutter head is hidden in a protection sheath so as to prevent normal tissues from being damaged in the process of breaking biological specimens. Meanwhile, the breaker also prevents a recovery bag from being damaged and prevents the sputtering of small specimens or tissue fluid in the process of breaking the biological specimen. Therefore, the present invention is safer and more reliable, and is convenient in use.
Description
Technical field
The present invention relates to a kind of surgical operating instrument, particularly the destroyer of broken biological sample under ESS.
Background technology
Endo-surgical is the Minimally Invasive Surgery of finishing by little otch, and this class operative incision is little, postoperative patient pain light, it is fast to recover, thereby has obtained application more and more widely.
But when implementing this type of operation,, can't take out, must enlarge otch, these biological samples are taken out, so just greatly reduce the superiority of endo-surgical by little otch if the biological sample of excision is too big; At this moment, need to adopt the biological sample destroyer that the bulk biological sample of excision is broken for the fritter biological sample, take out external.The cutter head of the destroyer of prior art all is to expose outside protective jacket, reach the destroyer of grinder, Chinese patent ZL97233972.8 under the GYNECARE board laparoscope of plate palace cutter, Johnson Co. etc. as homemade day loose plate palace cutter, doctor, these products have all reached the result of use of expection clinically.But also there are some problems in existing product in clinical use, and main problem is: need in the use to catch biological sample with operating forceps earlier, Yi Bian be pulled outwardly, Yi Bian cutting, it is convenient inadequately to use; Because cutter head exposes outside the protection sheath, causes the sputter of fine tissue or tissue fluid easily; And must extreme care when broken biological sample, with the antisitic defect normal structure; In addition, when in collection bag, handling the biological sample of excision,, scratch collection bag easily, cause the leakage of fine tissue or tissue fluid, cause infecting or the cancer cell diffusion because cutter head exposes outside the protection sheath.In order to overcome the above-mentioned shortcoming of prior art, need the destroyer of prior art be improved, the destroyer of biological sample in a kind of more safe and reliable processing body is provided, still do not have a kind of known biological sample destroyer at present and can reach this requirement.
Summary of the invention
Improved biological sample destroyer; comprise protection sheath (1), cutter head (2) and rotary main shaft (3); cutter head (2) is connected the far-end of rotary main shaft (3) or becomes one with the far-end of rotary main shaft (3); the centre bore of the centre bore of rotary main shaft (3) and cutter head (2) connects, and it is characterized in that described cutter head (2) is built in the protection sheath (1).
---the centre bore of above-mentioned rotary main shaft (3) and the centre bore of cutter head (2) connect, and link to each other with negative pressure source (4), form negative pressure region within protection sheath (1), near the cutter head (2).
---in the through hole (5) that the centre bore of above-mentioned rotary main shaft (3) and the centre bore of cutter head (2) form, can pass through surgical operating instrument.
---above-mentioned rotary main shaft (3) is gone up near having side opening (6) near the main shaft the cutter head.
The present invention's destroyer; owing to adopted cutter head to be hidden in the interior built-in structure of protection sheath; not only avoided in broken biological sample process damage to normal structure; also avoided simultaneously damage to the sample collection bag; and in the shattering process of biological sample, prevented the sputter of fine tissue or tissue fluid; more safe and reliable, easy to use.
Description of drawings
Fig. 1 is the structural representation of the present invention's improved biological sample destroyer.
Fig. 2 is the structural representation of the biological sample destroyer of the present invention's cutter head and integrated spindle axisization.
Among the above-mentioned figure, 1 is the protection sheath, and 2 is cutter head, and 3 is main shaft, and 4 is negative pressure source, and 5 is through hole, and 6 is near the side opening the main shaft cutter head, and 7 is surgery forceps, and 8 is biological sample, and 9 is gas tube, and 10 is collection bag, and 11 is peritonaeum, and 12 is bearing.
Specific embodiment
Embodiment 1: the rotary main shaft (3) by power drives drives cutter head (2) rotation that is installed in main shaft (3) front end; when surgery forceps (7) outwards drags biological sample (8); cutter head (2) with biological sample (8) fragmentation, and goes out external by the surgery clamp in protection sheath (1).Because cutter head (2) is built in the protection sheath (1); prevented effectively that not only cutter head (2) from damaging normal structure or collection bag because of the small error of operating; avoided the sputter of the fine tissue that in broken sample process, causes simultaneously, made the shattering process of biological sample safer.
Embodiment 2: in the present embodiment; cutter head (2) is the part of rotary main shaft (3); the front end that is about to rotary main shaft (3) manufactures the cutter head shape; and the centre bore of rotary main shaft (3) connected negative pressure source (4); when power drives rotary main shaft (3) rotates, drive cutter head (2) rotation because in protection sheath (1), cutter head formed negative pressure region near (2); biological sample (8) can be adsorbed near the cutter head (2), the biological sample of absorption (8) is external by cutter head (2) fragmentation and sucking-off.During clinical use, can earlier biological sample (8) be included in the collection bag (10), openend with the collection bag (10) that tightens up takes out from operative incision then, untie the openend of collection bag (10) then, in collection bag (10), insert gas tube (9), in collection bag (10), charge into carbon dioxide, collection bag (10) is heaved, insert the present invention's destroyer then, begin absorption and broken biological sample (8).When carrying out this operation, must guarantee the flow of the flow of aerating air of the interior carbon dioxide of collection bag (10) greater than the carbon dioxide of the present invention's destroyer sucking-off.
Should be noted that herein openly can replace with the identical structure of other effect that the embodiment that the present invention introduced simultaneously realizes unique structure of the present invention with the structure of explanation.Though preferential embodiment of the present invention is introduced in this article and is illustrated; but those skilled in the art know and know that these embodiment illustrate; those skilled in the art can make countless variations, improvement and replacement; and can not break away from the present invention; therefore, should be according to the next qualification protection scope of the present invention of the spirit and scope of appending claims of the present invention.
