Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of handle, and it belongs to parts in parts, especially the nasal sinuses clamp for sucking polypi in the medical calm, 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 handle 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 handle of wound.
The technical scheme in the invention for solving the above technical problem is: this handle comprises front hand grip and back handle, and front hand grip and back handle flexibly connect, and it is characterized in that: have cotter slot in described front hand grip upper end, have spring groove on back handle; Also be provided with the main body and the slide block of hollow, described main body and back handle welding; Slide block is installed in the endoporus of main body, also is welded with the slide block pin on described slide block, the cotter slot coupling of this slide block pin and front hand grip; In the spring groove of described back handle, spring is installed, and steel ball is installed on the top of this spring.Make thus and can realize Wicresoft and linear incision when this utility model cooperates with the nasal sinuses clamp for sucking polypi.
Slide block pin described in the utility model is connected in the cotter slot of front hand grip, can slide front and back by the switching of handle.
This utility model is provided with the main body female thread in described body front end, and the outer tube in the nasal sinuses clamp for sucking polypi is rotated.
This utility model is provided with the slide block female thread in described slide block rear end, can be connected with the attraction joint in the nasal sinuses clamp for sucking polypi.
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; Simultaneously, safe and reliable, and can dismantle with the nasal sinuses clamp for sucking polypi, convenient sterilizing can be stopped cross infection, and easy to operate.
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 front hand grip 1, back handle 2, main body 3 and slide block 4.Front hand grip 1 flexibly connects by arbor screw 5 with back handle 2, has cotter slot 11 in the upper end of front hand grip 1, has spring groove 21 on back handle 2; Main body 3 and slide block 4 are hollow structure, and promptly main body 3 and slide block 4 are through-hole structure; Main body 3 and back handle 2 welding, slide block 4 is installed in the endoporus of main body 3, on slide block 4, be welded with slide block pin 41, this slide block pin 42 mates with the cotter slot 11 of front hand grip 1, be that slide block pin 41 is connected in the cotter slot 11 of front hand grip 1, the switching by front hand grip 1 during use can be slided front and back; In the spring groove 21 of back handle 2 spring 6 is installed, the top of this spring 6 contacts with steel ball 7; Described steel ball 7 upper ends are positioned at the locating slot of the outer pipe connector sleeves of nasal sinuses clamp for sucking polypi, are used for the location of sheath.
During use, as long as the part of the sheath in this utility model and the nasal sinuses clamp for sucking polypi partly is connected with the attraction cutter head.And nasal sinuses clamp for sucking polypi and sheath part and attraction cutter head part are applied for a patent separately.
