Abstract
The utility model relates to an inner knife head, belonging to one part of sinus suction polypus pincers; the inner knife head is mainly applied to sinus operations of human body; the inner knife head comprises an inner knife head body and is characterized in that: an inner pipe and a suction joint are also arranged, the inner pipe is welded with the inner knife head body, and the suction joint is welded with the inner pipe; the inner knife head body, the inner pipe and the suction joint which are all hollow structures are sequentially arrayed. The structure design of the inner knife head is rational, mini-wound and linear cutting can be realized by matching with the sinus suction polypus pincers, tearing and pulling are reduced, the alignment of the edges of the wound surface is neat, and the healing is rapid; meanwhile, the usage is safe and reliable, the cross infection is eliminated, and the operation is convenient.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of interior cutter head, and it belongs to parts in the nasal sinuses clamp for sucking polypi, mainly is applicable in the operation on nasal sinus of human body.
Background technology
In the prior art, the clamp for sucking polypi that is used for operation on nasal sinus mainly contains two kinds of structures, a kind of is to make improvements slightly according to concrete needs to form on the basis of common medical calm, as the patent No. be 952333821, name is called the Chinese utility model patent of " nasal sinuses attracts pincers ", and the patent No. is 2005201356560, name is called the Chinese utility model patent of " nasal polypus forceps ", all belongs to this class formation; And the wound of the nasal sinuses of this class formation when attracting forceps operation is big, is not suitable for the nasal endoscope Minimally Invasive Surgery, and can only be applicable to the open surgery of nasal sinuses.Another kind is electronic Cutting instrument for cervical intervertebral disc hyperplasia class, as the patent No. be 032308752, name is called the Chinese utility model patent of " the medical electronic Cutting instrument for cervical intervertebral disc hyperplasia mobile phone of through type ", but the electronic Cutting instrument for cervical intervertebral disc hyperplasia of the nasal sinuses of this class formation is the rotation cutting when using owing to it, so it is uncontrollable when operation, promptly the moment of each cutting has only 0.0075-0.002 second, faulty operation is irreversible, causes damage to sinus tissue easily; Simultaneously, owing to cut direction and basis cranii, socket of the eye cardboard, the optic nerve of Cutting instrument for cervical intervertebral disc hyperplasia are vertical, increased operation risk.And as parts in the nasal sinuses clamp for sucking polypi, can there be the deficiency of bringing because of general defect in existing interior cutter head equally.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, can cooperates with the nasal sinuses clamp for sucking polypi and realize the little interior cutter head of wound.
The technical scheme in the invention for solving the above technical problem is: cutter head comprises interior body of tool bit in this, it is characterized in that: pipe and attraction joint in also being provided with, described interior pipe and interior body of tool bit welding, attraction joint and interior sealing of tube; Interior body of tool bit, interior pipe and attraction joint are arranged in order, and interior body of tool bit, interior pipe and attraction joint are hollow structure.
Attraction joint described in the utility model is provided with external screw thread.
This utility model compared with prior art has the following advantages and effect: reasonable in design, and cooperate with the nasal sinuses clamp for sucking polypi and can realize Wicresoft and linear incision, reduce tearing and turn round and drag, the para-position of wound surface edge is neat, and healing is rapidly; Safe and reliable, and can dismantle with the nasal sinuses clamp for sucking polypi, convenient sterilizing can be stopped cross infection.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, this utility model mainly is made up of interior body of tool bit 1, interior pipe 2 and attraction joint 3.Wherein: interior pipe 2 passes through laser weld with interior body of tool bit 1, attracts joint 3 and interior pipe 2 to pass through laser weld; Interior body of tool bit 1, interior pipe 2 and attract joint 3 to be arranged in order, and interior body of tool bit 1, interior pipe 2 and attract joint 3 to be hollow structure, cutter head hole 11 in having on the body of tool bit 1 in promptly has inner orifice 21 on the interior pipe 2, attracts to have on the joint 3 to attract nipple orifice 31; And attract joint 3 to be provided with external screw thread 32, so that can be connected with handle portion when using.
During use, as long as this utility model partly is connected with sheath with handle portion in the nasal sinuses clamp for sucking polypi.And nasal sinuses clamp for sucking polypi and handle portion and sheath part are applied for a patent separately.
