A kind of trend of development.It is divided into many types in Minimally Invasive Surgery, in common minimal invasive surgical procedures, can has an operation to increase
Space, doctor usually will use trochar.Existing trochar is mostly that needle is combined in casing syringe and puncture, is led to
It crosses casing syringe and can be passed in and out for various surgical instruments and channel be provided, when using trochar, it is often necessary to by trochar to body
Interior pushing, but existing trochar, since trochar is mostly without handle, applies pushing process when exerting a force pushing
Power is very uneven, so that patient be made to be easy to appear discomfort.
Utility model content
The purpose of this utility model is to provide a kind of simple micro-invasive operating trochars of structure, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of micro-invasive operating trochar, including casing syringe, puncture needle, handle, internal thread part and cushion, the set
The right part of pipe syringe is set there are two side opening, the opening directions of two side openings on the contrary, and two side openings not in trochar
On the same position of cylinder, and the spacing between two side openings is 0.5-1cm, the right end of casing syringe and the edge of side opening
It is shiny surface structure；The left end of described sleeve pipe syringe is equipped with casing head, and the left end of casing head is equipped with handle attachment part, and handle connects
The diameter of socket part is greater than the diameter of casing head, and handle is connected on handle attachment part, and handle left-hand face is equipped with one layer of buffering
The inside of pad, handle attachment part is equipped with internal thread part；The right part of the puncture needle is main needle body, and the left end of puncture needle is syringe needle,
Syringe needle is equipped with external thread part；The handle and handle attachment part are formed by same material integrated injection molding, and handle is symmetrical junction
Structure, the edge of handle are round and smooth structure.
Further: the handle attachment part and casing head are formed by same material integrated injection molding.
It is further: to be fixed together by way of gluing between the cushion and handle.
Further: the external thread part and syringe needle are formed by same material integrated injection molding.
Further: the external thread part and internal thread part are used cooperatively.
Compared with prior art, the utility model structure is simple, easy to use, and the setting of the side opening of setting is so that casing
Even if syringe is blocked by bodily tissue structure, suction and flushing work can be still carried out by side opening；The edge of handle
For round and smooth structure, round and smooth structure can reduce the friction between handle and medical staff's gloves, and handle can be prevented medical care people
The gloves of member on hand scratch, so that the progress of operation is influenced, in addition, the setting of cushion, so that handle and medical staff's palm
The contact surface of contact is more smooth, and can for force when buffering is provided, thus when effectively slowing down pushing patient sense of discomfort, more
Be conducive to the progress of puncturing operation.

Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
A kind of micro-invasive operating trochar referring to FIG. 1-2, including casing syringe 1, puncture needle 2, handle 6, internal thread part
10 and cushion 7, the right part of described sleeve pipe syringe 1 sets that there are two side openings 3, and the opening direction of two side openings 3 is on the contrary, and two
A side opening 3 is not on the same position of casing syringe 1, and the spacing between two side openings 3 is 0.5-1cm, trochar
The right end of cylinder 1 and the edge of side opening 3 are shiny surface structure, and shiny surface structure can reduce casing syringe and bodily tissue
Between friction, conducive to puncture movement progress, even if in addition, the setting of side opening 3 so that casing syringe 1 by bodily tissue knot
When structure blocks, suction and flushing work can be still carried out by side opening 3；The left end of described sleeve pipe syringe 1 is equipped with casing head
4, the left end of casing head 4 is equipped with handle attachment part 5, and handle attachment part 5 and casing head 4 are formed by same material integrated injection molding,
The diameter of hand interconnecting piece 5 is greater than the diameter of casing head 4, is connected with handle 6 on handle attachment part 5,6 left-hand face of handle is equipped with
One layer of cushion 7, is fixed together by way of gluing between cushion 7 and handle 6, and the inside of handle attachment part 5 is equipped with
Internal thread part 10.
As shown in Figure 3-4, the right part of the puncture needle 2 is main needle body, and the left end of puncture needle 2 is syringe needle 8, is set on syringe needle 8
There is external thread part 9, external thread part 9 and syringe needle 8 are formed by same material integrated injection molding, and external thread part 9 and internal thread part 10 cooperate
