Abstract
The invention relates to a medical apparatus applying in operations of patients' paranasal sinus and throat; in current technique, between knife bit, external sheath components, and inner knife components could not be detachable, therefore inner knife components couldn't be drawn and cleaned and sterilized, thus leading to cross-infection among patients, also it isn't convenient for use as there is no compound spring installed between inner knife bit and knife internal tube. In said invention, between inner knife bit components and external sheath components is of detachable structure , and between knife internal tube and knife bit there is compound spring which can move from left to right and connected to knife bit.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of Foldable nasal sinuses bent cutter head uses when it mainly is suitable for treating a patient nasal sinuses and operation on larynx.
Background technology
Nasal sinuses tulwar head of the prior art, it mainly is made up of outer sheath assembly and interior cutter head assembly, but by can not dismantling between outer sheath assembly and the interior cutter head assembly, so, interior cutter head assembly just can't be pulled out and be carried out cleanse and disinfect, causes cross infection easily between patient.Simultaneously, do not have between cutter head and the interior cutter pipe cluster spring that can turn left and right is installed, so convenient inadequately when reality is used.Chinese patent 200510050095.9 discloses a kind of power-driven cutter head, but it can only be the cutter head dismounting, blade part in whole all can not be pulled out, so its cleanse and disinfect still has problems.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing deficiency in the prior art, and provides a kind of outer sheath assembly can separate with interior sheath assembly, and can bear the Foldable nasal sinuses bent cutter head of the power of turning left and right.
The present invention addresses the above problem the technical scheme that is adopted: this Foldable nasal sinuses bent cutter head comprises outer sheath assembly and interior cutter head assembly, be provided with outer pipe connector sleeves, slip cap, outer tube spring and outer tube outside in the sheath assembly, in interior cutter head assembly, be provided with in slip ring, shaft joint spring, shaft joint, adapter sleeve and the cutter and manage, it is characterized in that: be removable structure in described between cutter head assembly and the outer sheath assembly, and in cutter the pipe and cutter head between be provided with the cluster spring that can turn left and right, this cluster spring is connected with cutter head.
Cutter head assembly is meant between them to being connected movingly with removable structure between the outer sheath assembly in of the present invention.
Pipe is provided with an inner pipe joint in the cutter of the present invention, and an end of described cluster spring is welded on this inner pipe joint, the other end of cluster spring and cutter head welding.
Cluster spring of the present invention is formed by three layers, and every layer of spring formed by the coiling of lengthy motion picture shape metal, socket between every layer of spring, and the two ends of adjacent layer spring are by being welded to connect, and the coiling direction of adjacent layer spring is opposite.
Its angle of bend of tulwar head of the present invention is: 20 °～120 °.
The present invention compared with prior art, have the following advantages and effect: 1. reasonable in design, novelty, interior cutter head assembly becomes removable structure with outer sheath component design, makes interior cutter head assembly cleanse and disinfect easily, has avoided the cross infection between the patient; 2. between interior cutter pipe and cutter head, be provided with cluster spring, can turn left and right easily, be difficult for blocking and rupturing, easier the carrying out of feasible thus operation.

The specific embodiment
Referring to Fig. 1-Fig. 6, the present invention mainly is made up of outer sheath assembly I and interior cutter head assembly II, is removable structure between them, is to connect movingly in the present embodiment, outer sheath assembly I passes through adapter sleeve 10 and slip cap 3 and interior cutter head assembly II part movingly, and sealing ring 1 seals.
Outer sheath assembly I of the present invention comprises sealing ring 1, outer pipe connector sleeves 2, slip cap 3, outer tube spring 4, diversion post 5 and outer tube 6, outer pipe connector sleeves 2 adopts laser weld with outer tube 6, slip cap 3 slides in the pipe connector sleeves 2 outside, diversion post 5 adopts laser weld with outer pipe connector sleeves 2, outer tube spring 4 slip cap 3 and outside between the pipe connector sleeves 2, outer tube 6 is a bend pipe.
Its angle of bend of tulwar head of the present invention is: 20 °～120 °; Be 40 ° in an embodiment.
Cutter head assembly II comprises pipe 11, cluster spring 12, cutter head 13 and inner pipe joint 14 in slip ring 7, shaft joint spring 8, shaft joint 9, adapter sleeve 10, the cutter in of the present invention; Slip ring 7 can slide in shaft joint 9, and shaft joint spring 8 is connected with slip ring 7 and shaft joint 9, and adapter sleeve 10 is bonding with shaft joint 9, and with cutter in pipe 11 laser weld; One end of cluster spring 12 and cutter head 13 laser weld, the other end and inner pipe joint 14 laser weld that are fixed on the interior pipe 11 of cutter.
This cluster spring 12 is formed by three layers, and every layer of spring formed by the coiling of lengthy motion picture shape metal, socket between every layer of spring, and the two ends of adjacent layer spring are by being welded to connect, and the coiling direction of adjacent layer spring is opposite.Be that it is combined by outer spring 15, middle level spring 16, internal layer spring 17, every layer of spring forms by the coiling of lengthy motion picture shape metal, when the coiling direction setting of outer spring 15 is forward (Fig. 5), then the coiling direction of middle level spring 16 is oppositely (Fig. 6), and the coiling direction of internal layer spring 17 is identical with outer spring 15; In like manner, if when the coiling direction of outer spring 15 is reverse, then the coiling direction of middle level spring 16 is a forward, and the coiling direction of internal layer spring 17 is identical with outer spring 15; That is to say that the coiling direction of adjacent layer spring is opposite.
Socket between outer spring 15, middle level spring 16, the internal layer spring 17, and a cluster spring 12 is formed thus by laser weld in the two ends of the two ends of internal layer spring 17 and middle level spring 16 and outer spring 15 and middle level spring 16.
This cluster spring 12 can forward and backward stretching and contraction, simultaneously, because the coiling direction of adjacent layer spring is opposite, also can turn left and right.
During use, interior cutter head assembly II is inserted among the outer sheath assembly I, again the present invention is connected with medical science power mobile phone and locatees, get final product work.If need to clean and sterilization, as long as interior cutter head assembly II is pulled out from outer sheath assembly I.
