Abstract
The utility model discloses a kind of type self-destroyed tissue-fetching bag, comprise collecting bag, elastic component, trocar sheath, handle and pull bar; The opening end of described collecting bag is provided with locking passage; Described elastic component one end is arranged in locking passage, is formed support the uncovered annular of collecting bag when collecting bag is opened; The other end of described elastic component is located in trocar sheath, afterbody cylinder lever connecting rod; Described handle is arranged on the afterbody of trocar sheath; Also comprise the agnail being arranged on incline direction on outer sleeve inner wall cannula exit toward the outside.This utility model arranges incline direction agnail outwardly at outer sleeve inner wall, also do not fill before getting tissue, collecting bag contracts in trocar sheath, because agnail is the guide channel being equivalent to a formation taper turned forward, therefore can very successfully pushing drawing rod, the head of collecting bag and elastic component is released, and has performed the operation, collecting bag is pulled back after trocar sheath, because collecting bag expands, will inevitably hang on agnail, damage self-destruction thus, can not reuse.
Description
Technical field
This utility model relates to a kind of type self-destroyed tissue-fetching bag.
Background technology
Need the operation of excising organ or tissue to be generally abdominal in surgical operation, along with popularizing of Minimally Invasive Surgery, the organ excised under how taking out Minimally Invasive Surgery and tissue become more and more urgent, have occurred thus getting thing bag product.
Existing thing bag bag mouth of getting opens and is separated with tightening device, complicated operation, and production technology is also more numerous and diverse; And trocar sheath is connected with outdoor handle and many adopts glue to fix, safety is with firm not, easily comes off.As Chinese patent literature 2013200015563 disclosed " one gets thing bag ", it comprises sterile gloves and silk thread, and sterile gloves comprises palm portion and finger part, and aseptic receiving removes finger part, only retains palm portion, and silk thread is tied in sterile gloves part.Such inadaptability in structure is in Minimally Invasive Surgery.As Chinese patent literature 2010102257731 disclosed " Novel endoscope object taking bag and delivery system ", comprise flexible pouch, elastic yarn, union joint, slide block.Elastic yarn can move ground through the through hole on the opening of flexible pouch.Elastic yarn can pass the through hole of slide block with moving, slide block can move along elastic yarn, although this structure can be put into get thing bag and open in vivo get thing bag, it is more difficult to take out, and do not have enough storages to take out the space of tissue, operate also convenient not.
More crucial a bit, in order to avoid infecting, gets thing bag and must guarantee it is disposable article, but existing thing bag of getting all not having self-destroying function, and lawless person cannot be stoped to reuse.
Utility model content
The purpose of this utility model be to provide a kind of can the type self-destroyed tissue-fetching bag of self-destruction, to guarantee to get thing bag for disposable medical instrument.
The technical scheme realizing this utility model object is a kind of type self-destroyed tissue-fetching bag, comprises collecting bag, elastic component, trocar sheath, handle and pull bar; The opening end of described collecting bag is provided with locking passage; Described elastic component one end is arranged in locking passage, is formed support the uncovered annular of collecting bag when collecting bag is opened; The other end of described elastic component is located in trocar sheath, afterbody cylinder lever connecting rod; Described handle is arranged on the afterbody of trocar sheath; Also comprise the agnail being arranged on incline direction on outer sleeve inner wall cannula exit toward the outside.
The afterbody of described pull bar arranges draw ring.
Described handle is fixed by lock banking stop and trocar sheath.
On the inner ring of described lock banking stop, uniform close arranges lock tooth.
Have employed technique scheme, this utility model has following beneficial effect: (1) this utility model arranges incline direction agnail outwardly at outer sleeve inner wall, so in use, also do not fill before getting tissue, collecting bag contracting is in trocar sheath, because agnail is the guide channel being equivalent to a formation taper turned forward, therefore can very successfully pushing drawing rod, the head of collecting bag and elastic component is released, collecting bag is opened, and performed the operation, collecting bag is pulled back after trocar sheath, because collecting bag expands, will inevitably hang on agnail, damage self-destruction thus, can not reuse.
(2) this utility model is opened by elastic component and tightens up storage bag mouth, and this design is ingenious, and owing to opening and tightening device integrated design, can reduce doctor's operation technique, lowers operating time, reaches the object alleviating patient suffering.
(3) be provided with the disconnecting prevention structure locking dentation between handle of the present utility model and trocar sheath, can be good at specifying with trocar sheath, avoid stickers such as using glue.
(4) pull bar afterbody of the present utility model arranges draw ring, operation of being more convenient for.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the A-A schematic diagram of Fig. 2.
Attached number in the figure is:
Collecting bag 1, elastic component 2, trocar sheath 3, handle 4, pull bar 5, draw ring 6, lock banking stop 7, lock tooth 71.
Detailed description of the invention
(embodiment 1)
See Fig. 1 to Fig. 3, the type self-destroyed tissue-fetching bag of one of the present embodiment, the opening end comprising collecting bag 1, elastic component 2, trocar sheath 3, handle 4, pull bar 5, draw ring 6 and lock banking stop 7. collecting bag 1 is provided with locking passage; Elastic component 2 one end is arranged in locking passage, is formed support the uncovered annular of collecting bag when collecting bag 1 is opened; The other end of elastic component 2 is located in trocar sheath 3, afterbody cylinder lever connecting rod 5; Handle 4 is arranged on the afterbody of trocar sheath 3; Trocar sheath 3 inwall is arranged incline direction toward the outside sleeve pipe 3 export agnail.The afterbody of pull bar 5 arranges draw ring 6.Handle 4 is fixed by lock banking stop 7 and trocar sheath 3.As shown in Figure 3, on the inner ring of lock banking stop 7, uniform close arranges lock tooth 71.
Under the original state used, collecting bag 1 is all positioned at trocar sheath 3, and doctor one only holds handle 4, a hand operated pull bar 5, first trocar sheath 3 head is stretched into the position that human body needs to take out tissue, then pushing drawing rod 5, thus elastic component 2 stretches out from trocar sheath 3, and form annular, collecting bag 1 is opened, after taking tissue, can pull bar 5, collecting bag 1 is set back in again in trocar sheath 3, abandons.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
