Abstract
The invention discloses a galea blunt detacher special for a gastrointestinal endoscopy. The galea blunt detacher comprises a detaching head, a support post and an outer sleeve; one end of the support post is connected with the bottom of the detaching head, and the other end of the support post is connected with the outer sleeve; the lateral dimension of the detaching head is greater than the longitudinal dimension; lateral edges on the top surface of the detaching head are gradually lowered from two sides to the middle; at least one lateral edge on the top surface of the detaching head is provided with forward sawteeth. The galea blunt detacher is compact, simple and reasonable in structure and is easy and convenient to operate, the occurrence rate of complications such as perforation and bleeding is reduced and the safety and the operability of an operation are improved.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of detacher.
Background technology
Existingly peel off operation and meet apparatus complex structure, processing technology requires high, expensive, technology dependence is strong, adnexa, equipment performance are required high, complicated operation, time-consuming, in art, postoperative have a big risk and severe complication probability of happening high, cause can not be in clinical treatment extensively promoting.
Summary of the invention
The present invention aims to provide a kind of digestive endoscopy Special cap shape inactive drcollement apparatus, and structure is small and exquisite, simple, reasonable, simple to operation, reduces the incidence rate of complication such as boring a hole, hemorrhage, improves safety and the operability of operation.
For achieving the above object, the present invention realizes by the following technical solutions:
Digestive endoscopy Special cap shape inactive drcollement apparatus disclosed by the invention, comprise stripping head, support column and trocar sheath, described support column one end connects stripping head bottom, other end outer sleeve for connecting, the lateral dimension of described stripping head is greater than longitudinal size, the widthwise edge of stripping head end face is reduced to both sides gradually by middle part, and whole stripping head forms a flat cap-like structure, and at least one widthwise edge of stripping head end face is along being provided with sawtooth forward; Can monolaterally there is sawtooth, also can all have sawtooth in both sides.Flat cap shape stripping head structure, can guarantee to connect level accurate, avoids Musclar layer damage, effectively prevents that perforation from occurring, and toothed edge can increase peels off the incision dynamics that is so that blunt separation pathological changes mucosa smoothly reduces labor intensity, saves operating time.
Preferably, the lateral dimension of described stripping head is greater than the external diameter of trocar sheath.Make whole detacher be cap-like structure, facilitate the position of observing stripping head in art.Trocar sheath contributes to launch the visual field and tela submucosa, and muscularis propria is produced to certain protective effect, thereby effectively prevents generation hemorrhage or perforation.
Preferably, described support column has 4, is connected to the position of close four jiaos of stripping head bottom.
Further, described stripping head offers duct, and described duct connects its end face and/or transverse side from the bottom surface of stripping head.If while there is hemorrhage situation in stripping process, can stop blooding immediately by passing hole channel importing high-frequency hemostatic forceps, also can import injection, inject and peel off and can carry out simultaneously, simplify the operation, guarantee that operation cause is clear.Also can absorb water by passing hole channel, prevent front end hydrops.
Further, the external diameter of described trocar sheath bottom internal diameter and scope head end is suitable.Make the present invention to be directly enclosed within on digestive endoscopy and to send in body.
Preferably, the material of described stripping head, support column and trocar sheath is transparent medical elastic material.
Preferably, the material of described stripping head, support column and trocar sheath is plastics or macromolecular material.
Adopt plastics or macromolecular material elastomeric material to make, can reduce the damage to tissue.
Preferably, the connecting portion of described duct and support column and stripping head bottom is not overlapping.While making to import high-frequency hemostatic forceps and support column do not interfere, handled easily.
Preferably, the orthographic projection of described stripping head end face is rectangle or ellipse.
Preferably, what the front end end face of described sawtooth was passivity is planar, rather than sharp-pointed wire or point-like, can avoid the damage of sawtooth to flesh layer.
Digestive endoscopy Special cap shape inactive drcollement apparatus disclosed by the invention, structure is small and exquisite, simple, reasonable, simple to operation, the incidence rate that reduces perforation, the complication such as hemorrhage, improves safety and the operability of operation, with low cost, technological requirement is low, be convenient to batch production, meanwhile, the present invention also can coordinate and synchronize use with the general apparatus of scope, does not need additionally to add equipment.

Fig. 1 is front view of the present invention;
Fig. 2 is side view of the present invention;
Fig. 3 is top view of the present invention;
Fig. 4 is upward view of the present invention.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, digestive endoscopy Special cap shape inactive drcollement apparatus disclosed by the invention, adopt the transparent medical poisonless elastomeric materials such as plastics or macromolecular material to make, comprise stripping head 1, support column 2 and trocar sheath 3, stripping head 1 end face is rectangle or ellipse, be that its lateral dimension is greater than longitudinal size, support column 2 has 4, one end of 4 support columns 2 is connected to stripping head 1 bottom near the position of four jiaos, the other end outer sleeve for connecting 3 of 4 support columns 2, stripping head 1 end face widthwise edge is along being provided with sawtooth 11 forward, what the front end end face of sawtooth 11 was passivity is planar, it can be plane, inclined-plane or cambered surface.The lateral dimension of stripping head 1 is greater than the external diameter of trocar sheath 3, and trocar sheath 3 bottoms are cylindrical, and the head end external diameter of its internal diameter and conventional digestive endoscopy is suitable, makes trocar sheath 3 can firmly be enclosed within the head end of digestive endoscopy.2 pairs of stripping heads 1 of 4 support columns have good supporting role, avoid being to greatest extent subject to gastrointestinal motility and the phenomenon that affects operation occurs as existing detacher.Whole detacher can 360 degree all-directional rotations, operation freely, is easy to grasp, and not limit by the region of anatomy and artificial institute, makes operation easier, quick.
Further, stripping head 1 offers duct 12, and the entrance in duct 12 is positioned at the bottom surface of stripping head 1, its outlet is positioned at end face or the transverse side of stripping head 1, also can all offer outlet at end face and transverse side, the entrance and exit in duct 12 is all avoided support column 2, and it is not interfered mutually.
Flat cap shape stripping head structure of the present invention, can guarantee to connect a level accurate, avoids Musclar layer damage, effectively prevents that perforation from occurring, one side
Certainly; the present invention also can have other various embodiments; in the situation that not deviating from spirit of the present invention and essence thereof; those of ordinary skill in the art can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
